자동차 부품기업은 재료비의 비중이 제조원가의 $70\%$이상 차지할 정도로 부품자재의 조달과 공급이 중요한 영역이며, 완성차를 제조하기 위한 공급망관리에 있어서 필수적인 분야라고 할 수 있다. 본 연구는 국내 자동차부품기업을 대상으로 공급망관리(SCM) 기능이 요구되는 부품조달 및 공급을 위한 자동차 부품업체간의 전자상거래를 활성화하기 위한 목적으로 전자조달(e-Procurement) 기업정보포탈(EIP) 시스템의 프로토타입 을 제안하였다. 제안된 e-Procurement EIP 시스템은 완성차 제조를 위하여 부품을 공급하는 1자 공급업체를 중심으로 2차 공급업체와의 부자재 및 MRO, 소모성 자재를 중심으로 하고 있으며 정보의 통합화를 위하여 중소기업간의 협업 프로세스의 개선, 안전한 XML 전자문서의 교환, 구매 일정관리 및 커뮤니티 형성, 부가서비스 기능 둠을 제공함으로써 부품기업간의 효율적인 협업체제 구죽 및 업무 신속성과 업무처리비용을 절감할 수 있다.

This study was conducted to investigate the quality characteristics of tofu (soybean curd) prepared with the addition of Enteromorpha intenstinalis powder (EIP). The moisture, crude ash, carbohydrate, crude protein, and crude lipid contents of the EIP were 6.04%, 24.09%, 39.68%, 28.25%, and 1.94%, respectively. The yield rate of the tofu did not differ significantly according to the level of added EIP, however there was a significant decrease in pH and a significant increase in acidity. The L and a values of the tofu color were decreased as the amount of EIP in the formulation increased, whereas the b values was increased. Furthermore, hardness and brittleness were significantly increased as the level of EIP increased. In terms of overall acceptability, the preferred tofu samples were the control and that of tofu mixed with 0.2% EIP addition group.

What kinds of environmental adaptation did people during the Chosun era take when climate change due to drought was perceived and natural disasters occurred? Research hypotheses is 'More environmental improvement projects were conducted when climate disasters were experienced than rituals for rain calling. In this study, frequency samples for Rituals for Rain (RR, 祈雨祭) defined as abnormal climate of drought, Climate Disaster(CD) and Environmental Improvement Projects(EIP) were extracted from "Chosunwangjoshillok(朝鮮王朝實錄)". The analysis among RR, CD, and EIP were studied for a regression model. Research hypothesis was statistically tested. RR took placed the order of Sejong(世宗), Sukjong(肅宗) and Youngjo(英祖), while climate disasters were extracted under the Jungjong(中宗), Sungjong(成宗) and Taijong(太宗). EIP were most active under Youngjo(英祖), Sungjong(成宗) and Taijong(太宗). During the former part of the Chosun dynasty, abnormal climate was more seriously considered than climate disasters, while the opposite pattern was shown during the latter part. In a regression analysis between EIP and CD, the equation of EIP = 0.632CD was determined. As a test result, the study hypothesis the entire Chosun dynasty was dismissed. However, it is possible to statistically support that more EIP were conducted in order to adapt to the climate change during the latter part of the dynasty when climate disaster were experienced.

Korean government has promoted nationwide Eco Industrial Park (EIP) project to recycle by-products and wastes in industrial park since 2010. However, the corresponding management is insufficient to support the project. Considering the efficiency and effectiveness, GIS-based management can be an alternative of the current status. This study has focused on the construction of recycling network based on EIP using GIS approach. Two industrial parks located in Gyeonggi province were selected as study sites. GIS-based spatial location analysis was performed to determine the optimal location of recycling company, and to identify linkage of one manufacture to the other manufacturers based on the types of waste. Also, the optimal network for recycling of waste heat was established. Finally, the feasibility of the current GIS-based recycling network was established by performing benefit-cost analysis.

An water-reuse network design has drawn attention as a systematic method of reducing fresh water usage and increasing water-using efficiency. The final goal of an eco-industrial park(EIP) is accomplishing industrial sustainability and constructing water-reuse network can be a solution. When designing water-reuse network connecting various processes which consume water, the water pinch technology can be used frequently, since it simultaneously minimize freshwater usage and wastewater discharge. In this research water pinch technology is applied to develop an effective water-reuse network in an EIP. Three scenarios based on different reusing strategies were developed. The results show that the final water-reuse network can reduce the total fresh water usage more than 30%, while the water expenses decrease by 20%. It can be concluded that water pinch technology is an effective tool to optimize water-reuse network among different industrial facilities.

Adaptive Random Testing through Iterative Partitioning(IP-ART) is one of Adaptive Random Testing(ART) techniques. IP-ART uses an iterative partitioning method for input domain to improve the performances of early-versions of ART that have significant drawbacks in computation time. Another version of IP-ART, named with EIP-ART(IP-ART with Enlarged Input Domain), uses virtually enlarged input domain to remove the unevenly distributed parts near the boundary of the domain. EIP-ART could mitigate non-uniform test case distribution of IP-ART and achieve relatively high performances in a variety of input domain environments. The EIP-ART algorithm, however, have the drawback of higher computation time to generate test cases mainly due to the additional workload from enlarged input domain. For this reason, a revised version of IP-ART without input domain enlargement needs to improve the distribution of test cases to remove the additional time cost. We explore three smoothing algorithms which influence the distribution of test cases, and analyze to check if any performance improvements take place by them. The simulation results show that the algorithm of a restriction area management achieves better performance than other ones.

The Adaptive Random Testing(ART) aims to improve the performance of traditional Random Testing(RT) by reducing the number of test cases to find the failure region which is located in the input domain. Such enhancement can be obtained by efficient selection algorithms of test cases. The ART through Iterative Partitioning(IP-ART) is one of ART techniques and it uses an iterative input domain partitioning method to improve the performance of early-versions of ART which have significant drawbacks in computation time. And the IP-ART with Enlarged Input Domain(EIP-ART), an improved version of IP-ART, is known to make additional performance improvement with scalability by expanding to virtual test space beyond real input domain of IP-ART. The EIP-ART algorithm, however, have the drawback of heavy cost of computation time to generate test cases mainly due to the virtual input domain enlargement. For this reason, two algorithms are proposed in this paper to mitigate the computation overhead of the EIP-ART. In the experiments by simulations, the tiling technique of input domain, one of two proposed algorithms, showed significant improvements in terms of computation time and testing performance.

This study assesses the strategy and performance of Eco-industrial Park (EIP) initiative implemented by Korea Industrial Complex Corporation (KICOX) with the support of Ministry of Trade, Industry and Energy (MOTIE), Korea since 2005 to 2013 and recommends future directions. After the concept of EIP based on industrial symbiosis (IS) is introduced, the background and implementation procedure of the EIP initiative are described. Then, economic and environmental achievement was assessed. During the project periods (2005-2013), 449 industrial symbiosis project were explored, among which 296 projects have been implemented. Among (Of these 296 projects,) them, 244 projects have been completed in which 118 projects have been commercialized which shows 48% commercialization rate of the completed projects. Through these commercialized projects, around 311.1 billion won/year of economic benefits and reduction of waste by-products of 828,113 tons/year, wastewater of 215,517 tons/year, reduction in energy consumption of 250,475 toe/year and GHG emission reduction of 1,107,189 $tCO_2/year$ were achieved. This results confirmed that EIP initiative based on industrial symbiosis can enhance eco-efficiency of industrial parks and harmonize economy and environment. However, there are obstacles like absence of interagency coordination and cooperation, laws and institutional barriers, increased demand for local governments, funding for project investment. Thus, to utilize EIP initiative as a strategic tool for competiveness and environmental management of industrial parks, it needs intergovernmental collaboration and interdisciplinary approach to lower barrier in implementation.
