While recent economic stagnation has left consumers dispirited, rapid growth has been seen in the domestic coffee industry recently. With the growth in coffee consumption, a tremendous increase in the number of specialty coffee shops has been seen in the domestic coffee market. The expectation that markets specializing in coffee will continue to grow for a long time will cause existing enterprises to expand their shops and increase the rate of entry of new shops. Intense competition in the domestic coffee market will force companies to create a competitive advantage through differentiated marketing strategies. This paper focuses on how the shopping value and repatronage intention of customers using coffee shops is affected by service quality. Moreover, this paper intends to examine the service quality that is critical for the successful management of relationships and the values that are important to consumers. For these purposes, the discriminative effect of service quality on shopping value was analyzed and the effect of utilitarian and hedonic value on repatronage intention was reviewed. The results of this study are detailed below. First, interaction and outcome quality can positively affect the hedonic value, whereas environment quality is not meaningful for utilitarian value. Considering the relative effect on utilitarian value outcome, the effect of outcome quality is greater than that of interaction. This result shows that the role of outcome quality is most important for improving utilitarian value. Second, outcome and environment quality positively affect hedonic value; however, interaction quality does not meaningfully increase hedonic value. These results indicate that customers recognize hedonic value on the basis of their evaluation of the service outcomes and the background to delivery service. In particular, it was revealed that the relative effect of outcome quality on hedonic value is greater than that of environment quality. Third, both utilitarian value and hedonic value had a positive effect on repatronage intention. The relative influence of the hedonic value is that the shopping value affects the repatronage intention more than the utilitarian value. These results mean that customers recognize coffee shops as spaces for satisfying utilitarian and hedonic values, and they place more importance on the benefits of the emotional experience than functional needs. Finally, this study suggests that output quality is more important than other service factors, and the results of this paper give some implications to the coffee shop industry that customers seek utilitarian needs based on economic value and place more weight on hedonic value, such as that offered by relationship media.

기업경쟁력의 중요한 결정요인의 하나는 제조부문의 관리능력이다. 제조부문을 효과적으로 관리하기 위하여는 기업전략에 부응하는 효과적인 제조전략의 수립과 실행이 요청된다. 본 논문에서 제기한 연구문제는 기업의 경쟁력을 높이기 위해 어떤 제조전략을 채택해야 하는가 였다. 이에 관련하여 본 논문에서 발견된 사실은 이러하다. 첫째, 생산관리자가 기업의 경쟁전략에 부응키 위하여 적극적으로 효과적인 제조전략을 수립하고 실행할 때 경쟁력은 증가하는데, 여기서 제조전략의 주 내용은 공장집중화이다. 둘째, 공장의 집중화는 효과적인 제조전략이다. 특히 소수의 과업에 촛점을 맞추는 것이 중효한데 이를 위해서 생산관리자는 단기적 성과에 집착하지 말고 장기적인 관점에서 어떤 과업에 촛점을 두어 집중화할 것인지를 판단하여야 한다. 또한 수동적으로 최고 경영자나 타 부문의 관리자의 요구에 응하지 말고 적극적으로 전략적 의사결정에 참여하여 공장의 과업을 결정하여야 한다. 본 연구의 의의는 제조전략의 변수로 지적되어 온 공장집중화에 관해 그 유효성을 실증적으로 검증하였다는 데에 있다. 또한 우리나라 제조업의 실무자들 및 최고경영자에게 실용적인 참고가 될 것이다.

Home service networked systems require a high-availability service with a proactive and practical fault management. However, as the system complexity grows, it is not easy to meet the requirement. Moreover, user may want to pay no attention to a sequence of complex or nervous maintenance jobs for system fault managements. Therefore, the home service networked systems must have self & remote fault management capability with a minimal human intervention for meeting high-availability requirement of the integrated systems that consist of the networked appliances or devices. In this paper, we present an autonomic healing utility equipped with a remote self-managing mechanism in order to both increase the availability of home service networked systems and decrease the maintenance cost.

This study is to investigate the compulsive use of the social media platform, YouTube. For this purpose, this study built a research model that considered how the personality trait perspective(agreeableness, conscientiousness, neuroticism, extraversion, openness) and the use motivation perspective(utilitarian, hedonic and social use motivations) work together to explain compulsive use of YouTube. The survey method was used for this paper, and data from a total of 165 were used for the analysis. And structural equation model was used to analyze the data. The results of this empirical study is summarized as followings. First, both agreeableness and conscientiousness have a negative effect on compulsive use of YouTube. Second, utilitarian use motivation has a negative effect on compulsive use of YouTube. The results of this study are meaningful in that it not only alerts YouTube users to the risks of compulsive YouTube use, but also helps them to develop self-management strategies.

This paper proposes a simple control chart method which can be practically used for asymmetric process data where the distribution is unknown. If we use the Shewhart type control charts which are based on normality assumption for the asymmetric process data, the type I error could increase as the asymmetry increases and the effectiveness of control chart to control variation decreases. To solve such problems, this paper suggests to calculate the control limits based on the quartiles. If we obtain the control limits by such quartile method, the type I error could decrease and it looks much more practical for asymmetric distributed process data.

수질오염총량관리제는 오염원에 대한 농도규제 방식에서 탈피하여 수계전체의 환경용량을 감안하여 원하는 목표수질을 유지하기 위해 허용할 수 있는 오염총량을 해당 배수구역에 할당하고 초과량은 적정수준으로 삭감토록 하는 광범위한 유역관리 기반의 수질정책이다. 금강수계에서는 1차 수질오염총량관리 기본계획($2004{\sim}2010$)하에 시행계획 및 이행평가가 진행 중에 있으나, 시행초기부터 현재에 이르기까지 제도정착을 위한 현안 문제점들이 제기되어 왔다. 지자체간 갈등을 줄이고 지역균형발전과 광역적 수질관리정책을 합리적으로 수행하기 위해서는 제기되어온 문제점들이 해결되어야 한다. 본 연구에서는 합리적인 오염배출부하량 산정을 위하여 2007년 청주시의 모든 동단위 오염원자료를 구축하고 오염부하량을 배출특성을 분석하였다. 또한 강우배출특성을 적용하기 위하여 하수 발생유량 실측자료와 오염원자료에 반영된 자료를 기초로 산정한 하수발생유량을 비교분석 하였다. 청주시 지역의 강우배출특성을 고려하여 보다 과학적이고 합리적인 방법으로 오염부하량을 산정함으로써 현상을 보다 정확히 반영하여 수질오염총량관리 시행상의 실용적인 오염부하량 산정 방안을 모색하고자 한다.

Recently, a few major construction companies in Korea have a growing interests to the risk management system, and they are trying to apply it to their construction projects. However, the existing methodologies to be applied to the foreign public projects are not proper to the construction environments due to its adaptabilities, that has one time process and heavily depends on personal judgement. The purpose of this paper is to propose a risk response process in consideration of the residual risks, which would be more adaptable and practical in the construction environment, overcoming the current obstacles to be mentioned above. This process has systematic repeat process until the residual risks go down to the risk thresholds based on the efficiency of specific response strategy.

구조물의 건전도를 평가하기 위하여 계측된 데이터로부터 구조물의 동특성 변화를 분석하여 손상정도를 추정하는 방법이 많이 사용되고 있다. 최근, 다점 측정된 가속도 데이터로부터 구조물의 고유진동수 및 모드형상을 추출하고 이를 초기값과 비교하여 손상탐지를 실시함으로써 손상위치 및 손상정도를 추정하는 기법이 활발히 연구되고 있다. 그러나 이러한 방법을 실제 적용하기 위해서는 계측시스템 구축에 많은 비용이 소요되며, 손상탐지를 위한 해석과정이 복잡하기 때문에 실시간에 가깝게 유용한 정보를 거주자에게 제공하는데 한계가 있다. 따라서 본 연구에서는 실용적인 계측유지관리 시스템을 구축할 수 있도록 구조물의 손상도에 따른 동적특성의 변화를 사전에 예측하여 실제 계측된 동적특성에 대한 관리 한계치를 제공하는 방안을 제시하고자 한다.

콘크리트 구조체공사의 가장 큰 영향을 미치는 것은 거푸집공사이며, 구조체공사의 합리적 관리는 거푸집공사의 작업생산성에 관한 기초자료를 확보함으로써 가능하다. 본 연구에서는 거푸집공사의 과학적 관리기반을 구축하기 위하여, 구조체 기준층을 대상으로 작업측정을 하여 유로폼공법, 재래식 거푸집공법 등 주요공법의 생산성을 도출하였다. 또한, 거푸집공사의 주요 작업인 조립, 해체, 운반등 단위 공정의 소요작업 품을 산출함으로써, 작업개선을 위한 실용적인 자료를 제시하였다. 마지막으로 거푸집 면적이 생산성과 상관관계가 매우 높다는데 착안하여 소요작업품을 예측할 수 있는 상관관계식을 유도함으로써, 공정관리 및 기능공의 수급예측이 가능토록 하였다.
