  • Any business activities may have impact on environment to a certain extent. Enterprises must find appropriate approaches to measure the impact on these environmental aspects, which can be used as the basis to direct enterprises' efforts to improve the environmental impact. The method used to evaluate significant factors in life cycle assessment standards is the one most commonly used by enterprises in general to measure environmental impact. By this method, the decisive factors of each environmental aspect are given scores according to the preset scoring standard of the organization. The scores are added up for each aspect and ranked to assess major environmental aspects. The drawback of this assessment method, that is, it ignores the degree to which each of these factors affects the environment, results in poor credibility. Therefore, this study attempts to solve some qualitative problems by applying to fuzzy theory, in particular, by identifying appropriate fuzzy numbers through fuzzy sets and membership function. Moreover, the study seeks to obtain a crisp value in the process of defuzzifization in order to make up for the shortfall of the original method in dealing with relative weight of decisive factors and thus increase its applicability and credibility. The department of light production of an electronics company is used as an example in this study to measure environmental aspects by employing both the traditional significant factor method and the fuzzy environmental impact assessment model proposed in this study. Based on verification and comparison of results, the model proposed in this study is more feasible as it reduces partiality in decision-making by taking the relative weights of decisive factors into consideration.

  • This study systematically compared two hybrid deterministic/Monte Carlo transport codes, ADVANTG/MCNP and MAVRIC, in solving a difficult shielding problem for a real-world spent fuel storage cask. Both hybrid codes were developed based on the consistent adjoint driven importance sampling (CADIS) methodology but with different implementations. The dose rate distributions on the cask surface were of primary interest and their predicted results were compared with each other and with a straightforward MCNP calculation as a baseline case. Forward-Weighted CADIS was applied for optimization toward uniform statistical uncertainties for all tallies on the cask surface. Both ADVANTG/MCNP and MAVRIC achieved substantial improvements in overall computational efficiencies, especially for gamma-ray transport. Compared with the continuous-energy ADVANTG/MCNP calculations, the coarse-group MAVRIC calculations underestimated the neutron dose rates on the cask's side surface by an approximate factor of two and slightly overestimated the dose rates on the cask's top and side surfaces for fuel gamma and hardware gamma sources because of the impact of multigroup approximation. The fine-group MAVRIC calculations improved to a certain extent and the addition of continuous-energy treatment to the Monte Carlo code in the latest MAVRIC sequence greatly reduced these discrepancies. For the two continuous-energy calculations of ADVANTG/MCNP and MAVRIC, a remaining difference of approximately 30% between the neutron dose rates on the cask's side surface resulted from inconsistent use of thermal scattering treatment of hydrogen in concrete.

  • Traditional Industries were planning the major role for Taiwan's economy. However, we need to face the competition from developing countries. Moving manufacturing department to other low salary countries, such as China, can only temporarily release some limited pressure. The final and complete solutions are to equip on R&D, refine techniques, improve management capabilities, upgrade business, and reform physique. Currently there are some ERP systems on the market; however, they are designed for common purpose and difficult to introduce into industry. The expensive price is another factor to make them be popular. In this research we will Object Oriented, Visual Modeling, ER Model and Windows Environment to develop an Integrated Management System for Sports Requisites Industries (IMSSRI). We will integrate all information from all departments such as development, business, material administration, manufacture, shipping, and financial. When development people construct the all modules, components, cutting molds, materials and accessories, IMSSRI will calculate all needed materials and cost for each product. This cost will be used for quotation to report to our customers. When customers confirm the order, system will transfer all necessary materials into Material Administration System. IMSSRI can generate manufacturing forms and material raw lists for manufacture department. All related information such as stocking, returning goods, material requesting, and material returning can be integrated so we can control all details of the whole enterprise. Through the help of this system, we hope we can save man-power, reduce human mistakes, raise management capabilities for tradition manufacturing industries and create another possibility of eternal operating for Taiwan's Industries.

  • Angiogenesis is crucial for solid tumor growth. By secreting angiogenic factors, tumor cells induce angiogenesis. However, targeting these angiogenic factors for cancer therapy is not always successful, suggesting that other factors may be involved in tumor angiogenesis. This work shows that 25 protein spots were differentially expressed by two-dimensional gel electrophoretic analysis when HepG2 cells induced endothelial cell differentiation to tube in vitro, and most of them were upregulated. Twenty-one proteins were identified with MALDITOF-MS, and the other four were identified by LTQ-MS/MS. Keratins were identified as one class of these upregulated proteins. Further study indicated that the expression of keratin 17 in cultured endothelial cells is likely microenvironment regulated, because its expression can be induced by HepG2 cells and bFGF as well as serum in culture media. Increased expression of keratins in endothelial cells, such as keratin 17, may contribute to the angiogenesis induced by HepG2 cells.

  • Alzheimer's disease(AD) is a geriatric dementia that is widespread in old ages. In the future AD will be the largest problem in public health service. From old times, much medicines have been used for treatment of dementia, but there is no medicine having obvious effects. AD is one of brain retrogression disease. So we studied on herbal medicine that have a relation for brain retrogression. From old times, in oriental medicine, senile disease such as dementia and AD is treated by exclusion of Tan(痰). But Vascular Dementia(VsD) is due to YuXue(瘀血). So in recent studies, Hua Xue Hua Yu(活血化瘀) medicine is used for precautionary and medical treatment. We studied on the effects for anti-Alzheimer in pCT105-induced neuroblastoma cell lines by Hyeolbuchukeo-tang(HCT). As the results of this study, in HCT group, the apoptosis in the nervous system is inhibited, the repair against the degeneration of Neuroblastoma cells by CT105 expression is promoted. These results indicate that HCT possess strong inhibitory effect of apoptosis in the nervous system and repair effect against the degeneration of neuroblastoma cells by CT105 expression.

  • This paper aims to stretch the technology acceptance model (TAM) approach by investigating a clothes rental network. One of the understudied geographies of the world economy is the large-scale international trade in clothes, which are consumed by Chinese consumers. An online (www.sojump.com) survey was conducted by including 303 Chinese respondents. Structural equation modeling (SEM) was used to test the proposed hypothesis. The results indicated that external influence has a significant impact on the perceived ease of rental. Furthermore, consumers' perceived ease of rental influences the attitude towards renting, and perceived ease of rental plays a complete mediating role between them. However, external influence has no significant impact on perceived usefulness, and consumers' perceived usefulness has no impact on rental intention. In addition, attitude towards renting works as an indispensable mediation between perception and behavior. This study highlights the role of perception, attitude, behavior on clothes rental, and provides guidance and suggestions for clothes rental platform.

  • In the current economic downturn, it is easy for consumers to be emotional and regret their fashion product purchases. The purpose of this paper was to understand the effect of customer regret on the dissatisfaction and repurchase intention of fashion consumers in China, which is the world's largest fashion trading country. A total of 275 participants were recruited from a Chinese online survey system (www.sojump.com). The SPSS 22.0 statistical package was used for various data analyses. This study conceptualized the positive relationship between customer regret and dissatisfaction and the negative relationship between dissatisfaction and the repurchase intention of fashion goods. The findings indicated that customer regret could be categorized into two distinct types, chosen and forgone regrets. Chosen regret had a greater effect than forgone regret on dissatisfaction. The negative influence of dissatisfaction on repurchase intention was weak in consumers with a high level of regret-solving effort. The results of this study will help fashion businesses retain their customers, thus gaining long-term and repurchase economic value for the fashion industry.
