Over the last decade, the field of supply chain management (SCM) and e-business has received an enormous amount of attention from practitioners and academicians. However, little has been known about how and to what extent small- to medium-sized enterprises (SMEs) are implementing SCM initiatives and e-business practices. This paper proposes a comprehensive research model and presents the survey results of these practices of SMEs located in Wisconsin and illinois, U.S., In terms of competitive strategy and priority, value chain activity priority, supply chain and e-business integration focus, SCM best practices implementation focus and challenges, and business performance. The analysis reveals several valuable insights into how SMEs should run their businesses in today's volatile, rapidly changing customer economy.

Because of the limited fossil resources and the need to avoid emissions and toxic waste the future energy supply will be based on a large portion of renewable energies: wind-, solar-, biomass- and geothermal energy. Focus is on the utilization of wind energy coming from onshore- and offshore-sites. Generating electricity from wind is state of the art and feeding large amounts of wind power into the electrical grid will create some additional problems. Suggestions concerning energy storage will be made and the problem of power quality is discussed.

Global variables can be read or modified by any part of the program, making it difficult to remember or reason about every possible use. Sometime it has tight couplings between some of other variables, and couplings between variables and functions. The main focus of this paper is to use call graph and the control flow analysis to design a model from where we generate the test cases for testing global variables.

Traceability has been held as an important factor in testing activities as well as model-driven development. Vertical traceability affords us opportunities to improve manageability from models and test cases to a code in testing and debugging phase. This paper represents a vertical test method which connects a system test level and an integration test level in testing stage by using UML. An experiment how traceability works to effectively focus on error spots has been included by using concrete examples of tracing from models to the code.

Models of South-North Korean economic integration have the problem of circular reasoning. While many studies argue that South-North Korean economic integration would contribute to alleviate security risks in the Korean peninsular, they emphasize the success of any economic model of inter-Korean economic integration is subject to favorable geo-political and security environment. It is a failure in distinguishing between goals and constraints. After identifying three major goals of South-North Korean economic cooperation, this study shows the trilemma among the goals; they are 1) formation of a complete economic community, 2) maintaining independent sovereignty of the two Koreas, 3) promotion of mutual economic interests. The trilemma suggests that it is theoretically impossible to achieve the above three goals at the same time. Only two goals are achievable simultaneously. This study argues that the most practical option is to pursue the combination of goals 2) and 3) considering the complex political and security environment around the Korean peninsular. Recognizing that North Korea is the least developed country in the Northeast Asia region, South Korea's initiatives for inter-Korean economic cooperation should focus on assisting industrialization and integration of the North Korea economy into the Northeast Asian regional production sharing structure. In view of the 'flying geese model' of the sequential industrialization in the region, the least developed economic status of North Korea can partially be explained by its failure to participate in the production network in the region as well as lack of effective implementation of appropriate industrial policy. Therefore, promotion of industrialization of North Korea should be the immediate goal of economic cooperation between North and South Korea. It is an interesting fact that North Korea has rapidly expanded its apparel exports in recent years. It could mean that the North Korean economy is actively responding to the dynamics of international comparative advantage structure, although the production activities are limited to exports to China since the closure of the Gaesung Industrial Complex. The recent increase in apparel export is a starting point for incorporating the Easy Import Substitution fulfilling both domestic and neighboring regional demand of North Korea. It could help integrate North Korea's industry into the production network of Northeast Asia. An immediate policy implication is that the economic cooperation between the two Koreas should focus on facilitating this process and supporting North Korea's industrial policy through South Korea's contribution of capital, technology, and service intermediary inputs.

The purpose of this study is to examine the relationship between internal corporate, supplier, and customer integrations for domestic SMEs on non-financial and financial performance through SCM performance such as flexibility and reduction of uncertainties. To this end, data was collected on 286 SMEs in Korea, and the structural relationships between SCM integration level, SCM performances, and management performance were analyzed. As a result of the analysis, first, it was found that the SCM integration level had a significant positive effect on the flexibility and reduction of uncertainties, which are SCM performances. Second, the flexibility and reduction of uncertainties showed significantly positive effects on the non-financial performance of the companies, but did not directly affect the financial performance positively. Third, the non-financial performance was found to have a positive effect on the financial performance. In addition, the SCM integration level did not have a direct effect on the financial and non-financial performance, but it was found that it affected management performance by mediating the flexibility and reduction of uncertainties, which are SCM performances. That is, although the SCM integration level did not directly affect financial and non-financial performance, it was confirmed that it affects management performance by mediating SCM performances, flexibility and uncertainty reduction. In other words, it was confirmed that the SCM integration level directly or indirectly affects SCM performances and overall management performance. These results imply the necessity to focus on competency in the supply chain management area according to the SCM performance expected by SMEs, and the step by step approaches to the expected effects. In a situation where prior SCM related studies have not been able to present SCM performances and management performance of SMEs that are relatively lacking in their capital and SCM construction capabilities, the findings of this study could suggest the importance of SCM integration from the perspective of SMEs. In addition, from the viewpoint of SMEs, this study suggested that a sequential approach for performance measurement is required (SCM performance → management performance) in relation to the performance factors to be established through SCM.

전자산업의 소형화와 경량화 추세에 맞추어 최근 집적 칩(IC)이나 패키지를 적층시키는 삼차원 집적화(3D integration) 기술 개발은 차세대 핵심기술로 중요시되고 있다. 본 연구에서는 삼차원 집적화 공정 기술 중 하나인 초박막 실리콘 웨이퍼 연삭(grinding)공정이 웨이퍼 표면에 미치는 영향에 대해서 조사하였다. 실리콘 웨이퍼를 약 $30{\mu}m$과 $50{\mu}m$ 두께까지 연삭한 후, 미세연삭(fine grinding) 단계까지 처리된 시편을 건식 연마(dry polishing) 또는 습식 애칭(wet etching)으로 표면 처리된 시편들과 비교 분석하였다. 박막 웨이퍼 두께는 전계방시형 주사전자현미경과 적외선 분광기로 측정하였고, 표면 특성 분석을 위해선 표면주도(roughness), 표면손상(damage), 경도를 원자현미경, 투과정자현미경 그리고 나노인덴터(nano-indentor)를 이용하여 측정하였다. 표면 처리된 시편의 특성이 표면 처리되지 않은 시편보다 표면주도와 표면손상 등에서 현저히 우수함을 확인 할 수 있었으나, 경도의 경우 표면 처리의 유무에 관계없이 기존의 벌크(bulk)실리콘 웨이퍼와 오차범위 내에서 동일한 것으로 보였다.

장기적인 경기침체가 지속되고, 환경의 변화가 급격하게 발생하는 오늘날, 기업이 환경에 어떻게 대처하는가는 그 기업의 매우 중요한 과제가 되었다. 본 연구는 최근 그 중요성이 부각되고 있는 수요부문 환경의 풍요성과 동태성이 만족, 신뢰, 결속 등과 같은 유통경로 시스템의 성과에 어떠한 영향을 미치는지 발견하는 것을 그 목적으로 하고 있다. 특히 본 연구는 기존 연구와는 달리 유통경로 시스템의 수직적 통합 수준에 따라 환경의 영향이 어떻게 달라지는지를 규명하는데 그 구체적인 목적이 있다. 이와 같은 목적으로 기업형 유통경로 시스템(우유 회사와 보급소), 계약형 유통경로 시스템(치킨 프랜차이즈 본부와 가맹점), 전통형 유통경로 시스템(화장품 회사와 거래 전문점)을 대상으로 설문조사를 실시하였으며, 조절변수 회귀분석을 수행한 결과 환경의 풍요성은 유통업체의 만족, 신뢰, 결속을 강화시킨 반면, 동태성은 약화시켰고, 수직적 통합의 수준은 이러한 영향을 더욱 강화하는 역할을 하였다.
