1 108/1 水環系 洪貞伶 助理教授 期刊論文 發佈 Impacts of combined land-use and climate change on streamflow in two nested catchments in the Southeastern United States , [108-1] 摘要:Stream restoration aims to improve hydrologic, geomorphic, and ecological processes and provides an opportunity for ecological design in an urban context. Urban stream restoration and stormwater management involve conventional and low impact development strategies that may employ ecological engineering techniques. Urban flood-risks may increase rapidly due to the combination of land-use and climate change. This is a major research frontier because the changes are poorly understood, especially for the combined impacts of climate and land-use change in small catchments. Climate and land-use change may affect hydrologic systems in a complex, non-linear, and non-additive manner. Streamflow simulation models can measure the relative magnitude of land-use and climate change on hydrologic response to precipitation events. Based on a simulation model calibrated with instrumental rainfall and streamflow data, this study compares simulated urban stormflow response to projected land-use and climate change in two highly urbanized catchments in Columbia, South Carolina, USA, using the U.S. Environmental Protection Agency (EPA)’s Storm Water Management Model (SWMM). Runoff responses for moderate-magnitude storms are contrasted using three land-use change scenarios with differing imperviousness and three climate-change scenarios. Land-use effects on runoff were proportionally greater in the smaller of the two catchments. At the headwater and downstream gauges, a warm/wet climate-change scenario caused larger increases than land-use changes in peak discharges and total event runoff volumes from late spring to early fall. The maximum monthly increase in peak discharge and total runoff volume from all simulations of climate change was for the warm/wet climate scenario in both catchments. However, the combined climate and land-use change scenario produced a 117.9% increase in peak discharge, a slightly (up to 8.6% in September) greater increase in peak discharge than the sum of changes from the individual scenarios (82.6% from climate change and 26.7% from land-use change) at the headwater gauge for the far term (2045–2074). These results suggest a complexity and nonlinearity of the impacts of combined land-use and climate change on hydrological processes, and have implications for stream restoration projects, integrated climate-impact assessments, urban planning, and policy decisions related to storm runoff and water quality.
2 107/1 水環系 洪貞伶 助理教授 期刊論文 發佈 An automated algorithm for mapping building impervious areas from airborne LiDAR point-cloud data for flood hydrology , [107-1] 摘要:Buildings, as impervious surfaces, are an important component of total impervious surface areas that drive urban stormwater response to intense rainfall events. Most stormwater models that use percent impervious area (PIA) are spatially lumped models and do not require precise locations of building roofs, as in other applications of building maps, but do require accurate estimates of total impervious areas within the geographic units of observation (e.g. city blocks or sub-watershed units). Two-dimensional mapping of buildings from aerial imagery requires laborious efforts from image analysts or elaborate image analysis techniques using high spatial resolution imagery. Moreover, large uncertainties exist where tall, dense vegetation obscures the structures. Analyzing LiDAR point-cloud data, however, can distinguish buildings from vegetation canopy and facilitate the mapping of buildings. This paper presents a new building extraction approach that is based on and optimized for estimating building impervious areas (BIA) for hydrologic purposes and can be used with standard GIS software to identify building roofs under tall, thick canopy. Accuracy assessment methods are presented that can optimize model performance for modeling BIA within the geographic units of observation for hydrologic applications. The Building Extraction from LiDAR Last Returns (BELLR) model, a 2.5D rule-based GIS model, uses a non-spatial, local vertical difference filter (VDF) on LiDAR point-cloud data to automatically identify and map building footprints. The model includes an absolute difference in elevation (AdE) parameter in the VDF that compares the difference between mean and modal elevations of last-returns in each cell. The BELLR model is calibrated for an extensive inner-city, highly urbanized small watershed in Columbia, South Carolina, USA that is covered by tall, thick vegetation canopy that obscures many buildings. The calibration of BELLR used a set of building locations compiled by photo-analysts, and validation used independent building reference data. The model is applied to two residential neighborhoods, one of which is a residential area within the primary watershed and the other is a younger suburban neighborhood with a less-well developed tree canopy used as a validation site. Performance results indicate that the BELLR model is highly sensitive to concavity in the lasboundary tool of LAStools® and those settings are highly site specific. The model is also sensitive to cell size and the AdE threshold values. However, properly calibrated the BIA for the two residential sites could be estimated within 1% error for optimized experiments. To examine results in a hydrologic application, the BELLR estimated BIAs were tested using two different types of hydrologic models to compare BELLR results with results using the National Land Cover Database (NLCD) 2011 Percent Developed Imperviousness data. The BELLR BIA values provide more accurate results than the use of the 2011 NLCD PIA data in both models. The VDF developed in this study to map buildings could be applied to LiDAR point-cloud filtering algorithms for feature extraction in machine learning or mapping other planar surfaces in more broad-based land-cover classifications.
3 109/2 水環系 蔡孝忠 副教授 期刊論文 發佈 Predicting Rapid Intensification Events Following Tropical Cyclone Formation in the Western North Pacific Based on ECMWF Ensemble Warm Core Evolutions , [109-2] 摘要:When the environmental conditions over the western North Pacific are favorable for tropical cyclone formation, a rapid intensification event will frequently follow formation. In this extension of our combined three-stage 7-day Weighted Analog Intensity Pacific prediction technique, the European Centre for Medium-range Weather Prediction ensemble predictions of the warm core magnitudes of pre-tropical cyclone circulations are utilized to define the Time-to-Formation (35 knots) and to estimate the Likely Storm Category. If that category is a Typhoon, the bifurcation version of our technique is modified to better predict the peak intensity by selecting only Cluster 1 analog storms with the largest peak intensities that are most likely to have under-gone rapid intensification. A second modification to improve the peak intensity magnitude and timing was to fit a cubic spline curve through the weighted-mean peak intensities of the Cluster 1 analogs. The performance of this modified technique has been evaluated for a sequence of western North Pacific tropical cyclones during 2019 in terms of: (i) Detection time in advance of formation; (ii) Accuracy of Time-to-Formation; (iii) Intensification stage prediction; and (iv) Peak intensity magnitude/timing. This modified technique would provide earlier guidance as to the threat of a Typhoon along the 15-day ensemble storm track forecast, which would be a benefit for risk management officials.

6 109/2 管科系 張紘炬 教授 期刊論文 發佈 Associations Between Lifestyle Factors and Reduced Kidney Function in US Older Adults: NHANES 1999–2016 , [109-2] 摘要:Objective: This study aimed to evaluate the associations between lifestyle factors and the estimated glomerular filtration rate (eGFR) levels in older adults by analyzing the United States National Health and Nutrition Examination Survey data (1999–2016). Methods: A total of 10,052 eligible participants were divided into two groups: reduced eGFR group (eGFR < 60 ml/min/1.73 m2 ) and normal group (eGFR ≥ 60 ml/min/1.73 m2 ). The primary factors were physical activity, alcohol consumption, smoking, and comorbidities. Results: Multivariable analysis revealed that older age, proteinuria, cardiovascular disease, diabetes, hyperuricemia, and hypertension were significantly associated with higher odds of reduced kidney function. Sufficient physical activity, current alcohol consumption, and being a current smoker were significantly associated with lower odds of reduced kidney function. However, subgroup analysis by sex revealed that the effects of proteinuria, current alcohol consumption, and sufficient physical activity were sex-specific. Conclusion: Several risk and beneficial factors for reduced kidney function in adults aged 65 and above in the United States were identified, but some of them might be sex-specific. Further studies are warranted to confirm these findings in other populations and countries

8 109/2 資工系 葛煥昭 教授 期刊論文 發佈 Coverage-Aware Recharging Scheduling Using Mobile Charger in Wireless Sensor Networks , [109-2] 摘要:Energy recharging in wireless rechargeable sensor networks (WRSNs) has acquired much attention in recent years. In literature, many recharging path construction algorithms have been proposed. Most of them considered that all sensors are equally important and designed algorithms to increase the number of recharged sensors or decrease the path length of the mobile charger. However, different sensors have different coverage contributions. Recharging the sensors with larger coverage contribution can achieve better surveillance quality. The proposed recharging scheduling algorithm is divided into three phases, including the Initialization, Recharging Scheduling and Path Construction Phases. In the second phase, this paper proposed two recharging scheduling algorithms, namely the Cost-Effective (CE) algorithm and Cost-Effective with Considerations of Coverage and Fairness (C2F) algorithm. The proposed two algorithms construct paths for the mobile charger and select the recharging sensors based on the higher weight in terms of larger coverage contribution and smaller path cost. Performance results show that the CE and C2F algorithms yield better performance in terms of the fairness of recharging, recharging stability and coverage ratio, as compared with the existing studies.
9 109/2 日本政經所 小山直則 副教授 期刊論文 發佈 CPTPPとRCEPへの参加動機としての潜在輸出額の推計 ―日本、米国、英国、中国、台湾の事例を中心に― , [109-2] 摘要:日本を含む11カ国のCPTPPは、2018年12月30日に発効した。また、2019年2月1日には、日本と欧州連合(EU)の日EU経済連携協定が発効した。2017年1月、米国トランプ大統領はTPPから離脱する一方、中国は2020年11月にCPTPP参加への前向きな検討を表明した。中国は2020年11月15日に、中国を含む15か国の地域的な包括的経済連携協定(RCEP)に署名した。英国は、2020年1月31日にEUを離脱したが、日本と日英EPAを2020年10月に署名した。日英EPAは、2021年1月1日に発効した。さらに、英国は、2021年2月1日にCPTPPへの参加を正式に申請した。いわゆるメガFTAへの参加に意欲的な国とそうでない国の違いをどのようにして分析すればいいであろうか? 本稿の目的は、50カ国のペア・パネルデータを用いて、総輸出額を重力モデルによって推計し、その予測値と実現値との差から潜在輸出額を推計することにある。本稿では、日本、米国、英国、中国、台湾に注目し、これらの5カ国の潜在貿易額を推計し、メガFTAへの参加動機について分析したい。CPTPP、RCEP、EUなどのメガFTAへの輸出の潜在貿易額の大きな国は、貿易費用を低下させることにより、輸出を拡大させることができると予測できるため、メガFTAへの参加が促進されると推測できるであろう。 本稿の主要な結果は、以下のとおりである。第一に、日本、米国、英国は、EUとの通商条約によって総輸出を拡大させる可能性が高いことがわかった。第二に、中国は、CPTPPやRCEPに参加することによって、輸出を拡大させる可能性が高いことが分かった。台湾について、頑健な結論が得られなかった。
10 109/2 化學系 王三郎 教授 期刊論文 發佈 Production of Sucrolytic Enzyme by Bacillus licheniformis by the Bioconversion of Pomelo Albedo as a Carbon Source , [109-2] 摘要:Recently, there has been increasing use of agro-byproducts in microbial fermentation to produce a variety of value-added products. In this study, among various kinds of agro-byproducts, pomelo albedo powder (PAP) was found to be the most effective carbon source for the production of sucrose hydrolyzing enzyme by Bacillus licheniformis TKU004. The optimal medium for sucrolytic enzyme production contained 2% PAP, 0.75% NH4NO3 , 0.05% MgSO4 , and 0.05% NaH2PO4 and the optimal culture conditions were pH 6.7, 35 ◦C, 150 rpm, and 24 h. Accordingly, the highest sucrolytic activity was 1.87 U/mL, 4.79-fold higher than that from standard conditions using sucrose as the carbon source. The purified sucrolytic enzyme (sleTKU004) is a 53 kDa monomeric protein and belongs to the glycoside hydrolase family 68. The optimum temperature and pH of sleTKU004 were 50 ◦C, and pH = 6, respectively. SleTKU004 could hydrolyze sucrose, raffinose, and stachyose by attacking the glycoside linkage between glucose and fructose molecules of the sucrose unit. The Km and Vmax of sleTKU004 were 1.16 M and 5.99 µmol/min, respectively. Finally, sleTKU004 showed strong sucrose tolerance and presented the highest hydrolytic activity at the sucrose concentration of 1.2 M–1.5 M.
11 109/2 機械系 劉昭華 教授 期刊論文 發佈 AgCl-based selective laser melting photocatalytic module for degradation of azo dye and E. coli , [109-2] 摘要:An innovative 3D printing procedure for producing a highly porous AgCl/Ag0 photocatalyst was developed and tested for its stability and degradability of azo dye (Orange II) and bacteria (Escherichia coli). The AgCl/Ag0 photocatalytic module was fabricated through selective laser melting (SLM), in which the AgCl powder was stacked in a thin layer (approximate average thickness of 30 μm) on a platform and melted by a high-power laser beam layer by layer until the 3D module was created. The melting process may cause AgCl to transform into other compounds, which may, in turn, reduce the activity of photocatalysts; for this reason, the optimal laser power and scanning speed for constructing an SLM module were investigated; they were determined to be 26 W and at 385 mm/s. This photocatalytic module effectively degraded azo dye and sterilized E. coli. The degradation of azo dye was performed under visible and UV light irradiation, and the degradation kinetics was first-order reactions. Furthermore, the azo dye degradability (95%) of this photocatalyst module persisted for five cycles in our experiment. The sterilization of E. coli was accomplished within a 135-min test, and the degradation kinetics was also first-order reactions. The photocatalytic module fabricated through SLM not only exhibited the ability to degrade contaminants in the water but also had durability and reliability after repeated use.
12 109/2 外交系 游雅雯 助理教授 期刊論文 發佈 在野黨的選舉策略與優勢政黨的敗選:伊斯蘭黨與2018年馬來西亞國會選舉的實證研究 , [109-2] 摘要:馬來西亞自1957年獨立以來,國民陣線(國陣)長期執政,並維持競爭式威權體制逾61年,直到2018年5月才首次政黨輪替。目前探討馬來西亞競爭式威權體制為何垮台的既有文獻指出:馬來西亞都市化的趨勢以及馬哈迪因素造成執政菁英分裂為兩大解釋國陣敗選之可能原因。本文結合政黨政治與族群投票的理論視角,主張伊斯蘭黨的政黨目標改變亦是導致國陣敗選的關鍵因素之一。具體而言,伊斯蘭黨的政黨目標從「追求官職」轉向「追求政策」—伊斯蘭黨為了推動伊斯蘭化政策,退出了過去二十年所加入的在野聯盟,因為民主行動黨時常與其因伊斯蘭議題發生衝突。結果伊斯蘭黨自立門戶之後,反倒成功吸引了那些先前對於伊斯蘭黨與民主行動黨結盟有所疑慮的馬來穆斯林選民。因此,本文假設伊斯蘭黨的參選將會對國陣的選舉表現造成影響。為了驗證這個假設,本文利用馬來西亞半島(西馬)165個國會選區在2018年國會選舉的資料進行量化分析。實證結果顯示,當伊斯蘭黨候選人與國陣候選人在同一國會選區競選時,國陣候選人會獲得較少的選票支持。
13 109/2 電機系 李揚漢 教授 期刊論文 發佈 Proposed Model for Performance Analysis of Fourth-generation Mobile Wireless Communication System , [109-2] 摘要:Both long term evolution (LTE) and IEEE 802.16m technologies have the advantages of a high transmission rate and wide transmission bandwidth, and they play essential roles in modern mobile wireless communication systems. The information transmission processes between mobile users and base stations inevitably involve some propagation losses. The losses include shadow fading loss due to blocking by buildings and obstacles and the Doppler effect caused by the relative motion of base stations and mobile users, and these effects result in signal fading at the receiver terminals. To maintain good system performance and service quality, the selection of a suitable modulation format is necessary when wireless signals are transmitted. Different traffic services have their own requirements of service quality. On the basis of the specifications of the IEEE 802.16m and LTE systems, we study their performance when the system parameters are varied. The system parameters include the system bandwidth, the transmitting powers of the base station and mobile, the antenna heights, the orthogonal frequency division multiplexing (OFDM) parameters, and the system load. We also analyze the system performances of the system bit error rate and block error rate (BER) due to the effects of path loss and noise.
14 109/2 資圖系 林雯瑤 教授 期刊論文 發佈 Effects of open access and articles‑in‑press mechanisms on publishing lag and first‑citation speed: a case on energy and fuels journals , [109-2] 摘要:Since the birth of first ever one in 1665, academic journals have long been recognized as one of the important formal channels for scholarly communication. Followed by the introduction of electronic journal, scholarly communication with significant reformation steps into a brand new era after singing the same old tune for hundreds years. It is therefore interesting to see how the electronic format affects time efficiency of communication via academic journals. In this study, differences on the time of communication between articles published under the open access (OA) model and in the article in press (AIP) format will be analyzed based on the characteristics of publication lag and first-citation speed. The correlation of publication lag and first-citation lag to the journal evaluation indicators will also be explored. A total of 24,176 journal articles collected from 64 journals indexed in the JCR Energy and Fuel field, one of the hot research topics recently, are selected as research objects. Publication and first-citation lags of these articles are calculated separately based on the submission date, revised date, accepted date, publication date, and month of the first-citation occur. Results demonstrate that the OA mechanism can influence the lag of publication, but it does not form a citation advantage. The AIP mechanism affects citation speed but is not significantly related to publication lag. It can be seen that OA and AIP mechanisms contribute to the efficiency of scholarly communication at different stages.
15 109/2 數學系 張玉坤 教授 期刊論文 發佈 Explore the Effects of Pharmacological, Psychosocial, and Alternative /Complementary Interventions in Children and Adolescents with Attention-Deficit/Hyperactivity Disorder: Meta-regression Approach , [109-2] 摘要:Background Till now, there have been various therapies for attention-deficit/hyperactivity disorder (ADHD), but the previous meta-analysis of ADHD efficacy remains unclear. This study aims to systemically meta-regress the effect sizes of psychostimulant pharmacotherapy (methylphenidate and lisdexamfetamine), non-stimulant pharmacotherapy (atomoxetine and alpha-2 agonists), psychosocial therapy (parental behavioral therapy [PBT]), combination therapy (psychostimulant plus PBT), and alternative/complementary interventions to determine the right treatment for ADHD. Methods We searched various ADHD interventions from the MEDLINE and PubMed databases (National Center for Biotechnology Information) between January 1, 1980 and July 30, 2018. Following the metaanalysis of random effects, the meta-regression analyses were used to explore factors potentially influencing treatment efficacy. The confounding variables included type of treatment, type of study, age, type of symptom scale used, and year of publication. Results A total of 107 trials (N = 9883 participants) were included. After adjustment, compared to the psychostimulant therapy (28 trial, 2134 participants), non-stimulant pharmacotherapy (28 trials, 4991 participants) and alternative/complement intervention (25 trials, 1195 participants) were less effective by the effect sizes (ES) of -0.384 (p = 0.004) and -0.419 (p = 0.028) respectively. However, compared to psychostimulant, PBT (19 trials, 1122 participants; ES = -0.308, p = 0.095) and combination of psychostimulant and PBT (7 trials, 441participants; ES = -0.196, p = 0.209) did not differ significantly. Conclusions Psychostimulant therapy surpassed non-stimulant pharmacotherapy and alternative/complement intervention. Psychostimulant therapy, PBT, and combination of psychostimulant therapy and PBT appear to be similar in efficacy according to this meta-regression.

17 109/2 會計系 郭樂平 教授 期刊論文 發佈 Ambitious corporate climate action: Impacts of science-based target and internal carbon pricing on carbon management reputation-Evidence from Japan , [109-2] 摘要:Under national climate change countermeasures, some Japanese firms have set science-based targets (SBT) for carbon emission to achieve the goal of keeping global warming below 2°C. Some scholars proposed that by implementing an internal carbon pricing (ICP) strategy, firms can prepare themselves for the uncertainties of external carbon pricing in advance. Can Japanese firms effectively utilize these practical carbon management tools (strategies) (i.e., SBT and ICP) to enhance their carbon management reputation (CMR)? CMR can be regarded as an important indicator of low-carbon competitiveness in future international trade. So far, this topic has never been explored. Based on this perspective, this study focuses on the period of 2016–2019 after the Paris Agreement went into effect. The full samples consist of 1,994 Japanese firms using ordinal logistic regression. The empirical results indicate that, overall, Japanese sample firms which set SBT or implemented ICP strategy have better CMR, but the odds ratio (OR) of setting SBT is higher than that of ICP on enhancing CMR. Besides, implementation of both SBT and ICP approaches can create a significant complementary or additional effect on the improvement of CMR for only firms in high carbon emission industries (HCEI). The practical implication of this study is that HCEI’s managers are advised to adopt both SBT and ICP mitigating climate change risk in an ever-evolving regulatory. Further, it is not cost-effective for non-high carbon emission industries (NHCEI) to implement both SBT and ICP simultaneously. Instead, priority setting SBT will be more appropriate for NHCEI in improving CMR. How should firms’ managers of different carbon emission attributes effectively utilize SBT and/or ICP to enhance their CMR in Japan? The aim of this study is to fill related evidences.
18 109/2 企管系 吳坤山 教授 期刊論文 發佈 The association between fear of coronavirus disease 2019, mental health, and turnover intention among quarantine hotel employees in China. , [109-2] 摘要:During the coronavirus disease 2019 (COVID-19) pandemic, quarantine hotel employees face a higher risk of infection while they host quarantine guests from overseas. This is the first research to empirically investigate the psychological effects of operating a quarantine hotel on its employees. The empirical results indicate that heightened fear of COVID-19 leads to adverse mental health issues for quarantine hotel employees and confirm that depression, anxiety, and stress have a significant influence on turnover intention. These findings contribute to the extant knowledge base by uncovering the role of mental health in employee turnover intention. Based on the results, implications are presented for practitioners.
19 109/2 企管系 吳坤山 教授 期刊論文 發佈 Leader-member exchange fosters nurse's job and life satisfaction: The mediating effect of job crafting , [109-2] 摘要:This study aims to evaluate the effects of leader-member exchange (LMX) on job and life satisfaction among nurses in China and to examine the mediating effect of individual and collaborative job crafting between LMX and job and life satisfaction. The study recruited 263 nurses who worked in hospitals in Zhejiang province, China. A set of self-administered questionnaires were used to measure the variables of LMX, job crafting, job and life satisfaction. The data was analyzed using the partial least square structural equation modelling (PLS-SEM). The results reveal that LMX has a significant positive influence on job crafting and job satisfaction. Collaborative job crafting has a significant positive influence on the job satisfaction of nurses, whereas individual job crafting does not. Moreover, LMX will affect job satisfaction and life satisfaction through a partial mediating effect of both individual and collaborative job crafting. Finally, the article discusses the academically and practical implications, and also provide some suggestions and directions for the future research.
20 109/2 學動組 王豐家 助理教授 期刊論文 發佈 Mechanisms of mindfulness for professional golfers: the mediating role of basic psychological needs , [109-2] 摘要:The relationship between mindfulness and well-being and ill-being has been demonstrated to a great extent. In sports, the fulfillment of individuals’ basic psychological needs depends mostly on support from others, such as that from a coach in a sports team context. However, a possible way for individuals to fulfill their basic psychological needs is by enhancing mindfulness rather than depending on others. Therefore, building on SDT and mindfulness, this study examines the mediating effect of basic psychological needs on mindfulness to predict subjective vitality and athlete burnout in professional golfers. The participants were 120 golfers (47% females), with a mean age and golf experience of 22.28 and 9.48 years, respectively. The association between mindfulness and subjective vitality was partially mediated by the need for autonomy and relatedness. By contrast, the association between mindfulness and burnout was partially mediated by the need for competence and relatedness, thus supporting our mediation analysis. Overall, the study highlights mindfulness as a potential mechanism to ensure the fulfillment of basic psychological needs in golf training, which could enhance golfers’ subjective vitality and reduce the occurrence of burnout.

22 108/2 未來學所 鄧建邦 教授 期刊論文 發佈 Labor Migration from Southeast Asia to Taiwan: Issues, Public Responses and Future Development , [108-2] 摘要:Purpose This paper is mainly focused on labor migration from Southeast Asia to Taiwan, showing a route of south–south mobility and discussing the causes of migrant workers in Taiwan, the issues faced by migrant workers as well as public response to migrant workers. Design/methodology/approach Besides a literate review on the topic of migrant worker researches in Taiwan, the data for this research was also based on qualitative interviews and observations conducted both in the fieldwork in Taiwan and in Indonesia between June and August during the summer of 2018. Findings The transnational mobility let many migrants from Southeast Asian countries to Taiwan end up losing their cultural capital and “make money” instead. For these migrants, they have experienced a downward social mobility of class through transnational mobility. Research limitations/implications Because of the chosen research approach, the research results may lack generalizability. More migrant laborers from various origin countries were encouraged to include for further research. Practical implications Labor migration cases from Southeast Asia to Taiwan could very well serve as good examples in the carrying out of a reflection on the limit of focusing on social science only inside nation-states in order to push a forward thinking on the transnationalization of social inequality. Originality/value This paper calls attention to the close linkage between transnational mobility and social inequality. It showed how the transnationalization of social inequality could get new faces through the new waves of labor migration.
23 109/2 化學系 鄧金培 副教授 期刊論文 發佈 Efficient small toxic gaseous molecule scavengers in metal-defective graphene: A density functional analysis , [109-2] 摘要:The adsorption property of small toxic gaseous molecules (SO2, SO3, H2S, and N2O) with metal/hexa-vacancy defective graphene (denoted as HDG-M, M: Fe2+, Co2+, Ni2+, Cu2+, and Zn2+) was determined by density functional theory. The results of these calculations show that the Fe2+ ion has the best and Cu2+ the worst absorption ability to capture all of the above toxic gases with selected adsorption orientation. These results can provide useful information for the application of the designed HDG-M adsorbents in food science and ecosystem monitoring.
24 109/2 化學系 王三郎 教授 期刊論文 發佈 Bio-processing of marine chitinous wastes for the production of bioactive prodigiosin , [109-2] 摘要:Recently, microbial prodigiosin (PG) has received much attention due to its numerous beneficial applications. The aim of this study was to establish the bioprocessing of marine chitinous wastes (MCWs) for the cost‐effective preparation of PG. Of the MCWs, demineralized shrimp shell powders (de‐SSP) were found to be a potential source of carbon/nitrogen (C/N) for PG production by bacterial fermentation using Serratia marcescens strains. Further, PG scale‐up production was in‐ vestigated in a 15 L bioreactor system, and the highest yield (6200 mg/L) was achieved during fer‐ mentation using 5 L of a novel‐designed culture broth that included 1.60% C/N sources (a de‐SSP/ca‐ sein ratio of 7/3), 0.02% K2SO4, and 0.05% K2HPO4, with an initial pH of 6–7. Fermentation was con‐ ducted in the dark at 27.5 °C for 8.0 h. This study was the first to report on the utilization of shrimp wastes for cost‐effective, large‐scale (5 L/pilot) PG production with high productivity (6200 mg/L) in a short cultivation time. The combination of 0.02% K2SO4 and 0.05% K2HPO4 was also found to be a novel salt composition that significantly enhanced PG yield. The red compound was purified and confirmed as PG after analyzing its HPLC profile, mass, and UV/vis spectra. The purified PG was then tested for its bioactivities and showed effective anticancer activities, moderated antioxi‐ dant activities, and novel anti‐NO effects.
25 109/2 電機系 蔡奇謚 教授 期刊論文 發佈 Manipulation Planning for Object Re-Orientation Based on Semantic Segmentation Keypoint Detection , [109-2] 摘要:In this paper, a manipulation planning method for object re-orientation based on semantic segmentation keypoint detection is proposed for robot manipulator which is able to detect and re-orientate the randomly placed objects to a specified position and pose. There are two main parts: (1) 3D keypoint detection system; and (2) manipulation planning system for object re-orientation. In the 3D keypoint detection system, an RGB-D camera is used to obtain the information of the environment and can generate 3D keypoints of the target object as inputs to represent its corresponding position and pose. This process simplifies the 3D model representation so that the manipulation planning for object re-orientation can be executed in a category-level manner by adding various training data of the object in the training phase. In addition, 3D suction points in both the object’s current and expected poses are also generated as the inputs of the next operation stage. During the next stage, Mask Region-Convolutional Neural Network (Mask R-CNN) algorithm is used for preliminary object detection and object image. The highest confidence index image is selected as the input of the semantic segmentation system in order to classify each pixel in the picture for the corresponding pack unit of the object. In addition, after using a convolutional neural network for semantic segmentation, the Conditional Random Fields (CRFs) method is used to perform several iterations to obtain a more accurate result of object recognition. When the target object is segmented into the pack units of image process, the center position of each pack unit can be obtained. Then, a normal vector of each pack unit’s center points is generated by the depth image information and pose of the object, which can be obtained by connecting the center points of each pack unit. In the manipulation planning system for object re-orientation, the pose of the object and the normal vector of each pack unit are first converted into the working coordinate system of the robot manipulator. Then, according to the current and expected pose of the object, the spherical linear interpolation (Slerp) algorithm is used to generate a series of movements in the workspace for object re-orientation on the robot manipulator. In addition, the pose of the object is adjusted on the z-axis of the object’s geodetic coordinate system based on the image features on the surface of the object, so that the pose of the placed object can approach the desired pose. Finally, a robot manipulator and a vacuum suction cup made by the laboratory are used to verify that the proposed system can indeed complete the planned task of object re-orientation.
26 105/2 財金系 聶建中 教授 期刊論文 發佈 企業社會責任之於公司經營績效受企業規模大小不同之變化影響 , [105-2] 摘要:近些年來,企業社會責任(CSR)已成為一門顯學,廣泛受到學術界、實務界、或是政府部門之所重視,CSR更已成為多數企業作為企業規劃經營之策略與企業長期發展目標的主軸;然而,企業規模之大小,對善盡CSR之成效展現恐有不同。本研究旨在進行CSR對企業經營績效(CFP)之影響,是否會受到企業規模大小之不同而有所差異之探討。利用天下雜誌所提供的2007年至2014年「天下企業公民TOP50」獎項調查結果作為CSR指標,並以台灣經濟新報所提供之間台灣上市、櫃公司資料進行實證觀察。本研究有別於以往文獻純以線性角度探討CSR及CFP關係,研究方法運用González, Teräsvirta, & van Dijk(2004, 2005)所發展之縱橫平滑移轉迴歸模型(PSTR),以企業規模大小作為門檻變數,進行非線性角度的CSR對CFP之影響在不同資產規模下的變化探討。研究首先確認CSR與CFP兩者之間存在著非線性之關係。再進一步發現,在評比樣本中,總資產在新台幣32,591,000元與33,983,000元之間時,CSR對CFP呈現顯著負向影響。然而,當企業規模總資產在新台幣32,591,000元之下或33,983,000元之上時,CSR則對CFR之影響,呈現顯著的正向影響。研究推論,小型企業善盡CSR,有機會增加企業形象的建立以及曝光率,進而強化CFP;大型企業若善盡CSR,在一定的社會認知基礎上,將可更增加企業聲譽,進而更有機會增強消費者對該企業及其所提供商品及勞務的信心,CFP也因此提升。然而,研究所得企業規模總資產在兩門檻值之間的中型企業,由於社會認知度尚且不足,即便投入較多資本在CSR上,不但未能讓CFP提升,反倒有可能因為對於CSR的過多投資,而侵蝕到企業原本的經營獲利,使CFP不致增加、反倒減損。
27 108/1 財金系 聶建中 教授 期刊論文 發佈 The Asymmetric Contagion Effect from the U.S. Stock Market around the Subprime Crisis between 2007 and 2010 , [108-1] 摘要:This study employed Enders and Siklos asymmetric co-integration frameworks, including the momentum threshold autoregressive (M-TAR) and logistic smooth transition co-integration (LSTC) models, to investigate whether contagion effects had existed in international stock markets by using the changes in the asymmetric co-integration relationships between the U.S. S&P 500 Index and a total of 23 markets in Asia, Europe, and America during the subprime crisis. The main findings demonstrated that the subprime crisis did not reinforce co-movement trends between the S&P 500 Index and these stock markets, by the application of the Engle-Granger (1987) symmetric co-integration test. However, with the application of the asymmetric co-integration frameworks, both MTAR and LSTC showed there existed contagion effects between them in the aftermath of Lehman Brothers’ bankruptcy in 2008; transition speeds between these two regimes also substantially increased in the LSTC during the financial crisis. Only the Chinese market was not affected by the U.S. market during this crisis; only an interdependence effect existed between the U.S. and China. The subprime crisis determined the degree of contagion, depending on the financial linkage to the U.S. market, which further demonstrates the differences in the causes and influence between the subprime crisis and other financial crises in emerging markets
28 107/2 航太系 馬德明 教授 期刊論文 發佈 Design, Manufacturing, and Flight Testing od an Experimental Flying Wing UAV , [107-2] 摘要:This paper presents the design, manufacturing, and flight testing of an electric-powered experimental flying wing unmanned aerial vehicle (UAV). The design process starts with defining the performance requirements including the stall speed, maximal speed, cruise altitude, absolute ceiling, and turn radius and speed. The wing loading and associated power loading are obtained based on the defined performance requirements. The wing area, UAV mass, and power requirements are determined from the endurance and payload requirements. The power requirement determines the motor size. Aerodynamics and stability designs are obtained based on the selected airfoil and obtained wing area. After completing the design, the UAV is manufactured using composite materials. The UAV is equipped with an AXi 4130/20 kv305 brushless motor and a Pixhawk flight control board. Its total weight is 8.6 kg. Flight tests were conducted to evaluate the UAV’s performance and dynamic characteristics and to demonstrate the success of the design.
