This paper aims to investigate the moderating effects of strength and opportunity factors between entrepreneurship of food service franchisor's CEO and performance in hood service franchise. For analyzing the relationship of them, the entrepreneurship factors categorized with organizational risk taking, innovativeness, and proactiveness from previous researches(Khandwalla, 1977; Miller, 1983; Miller, 1983). Also, strength and opportunity factors classified into detailed subfactor by confirmatory factor analysis. As a result, we found some statistically significant effects between the strength and opportunity factors and entrepreneurship factors, and they sequentially affects to performance. This result means that strength and opportunity factors have a role as a moderating variables. That is, as a presented with previous research, there is verified that entrepreneurship is caused by organizational risk taking, innovativeness, and proactiveness. Also, strength and opportunity factors significantly affect to business performance. Some guidelines for practicing potential food service franchise as a result of this would include; first of all, it is important to support the potential food service franchise consulting approach for some competitive advantage; secondly, effective governmental support programs for food service franchise should be developed for positive impacts of according to these results.

The purpose of this research is to identify new service opportunities for enhancing driving safety of intra-city buses based on driving behavior analysis. Service opportunity identification involves finding target customers of service (to whom), motivations for service (why), service contents (what), and service delivery process (when, where). This paper presents an analysis of driving behaviors using the operational data of intra-city buses in conjunction with traffic accident data and drivers' driving history data. This paper also presents four identified service opportunities based on the data analysis results. This research would contribute to enhancing driving safety of intra-city buses in Korea and serve as a basis for developing new services for driving safety enhancement.

Among service industries of knowledge based economic era, the roles of educational service field are becoming more important and standard of educational service makes a direct effect on economic development and social growth. Therefore, accurate measurement of service quality is the most important assignment and the measurement of the service quality remains difficult assignment. So, this researcher classified quality attributes applying weighted value and found potential satisfaction level(PSL) and potential customer demand improvement index(PCDI) for trainees participating in national manpower business so as to suggest measurement of service quality and easiness of use and then, calculated satisfaction position and opportunity cost by quality factor with Taguchi's loss fraction. And, improvable satisfaction level was measured, opportunity cost by degree of customer dissatisfaction was quantitatively measured, and a model that can indicate with economic factors was suggested. In addition, methodology of measuring quality cost that can be reduced by quality improvement and direction of strategic decision-making for deciding items to be improved preferentially were suggested with qualitative index that can indicate the degree of customers' dissatisfaction by loss.

This paper deals with a denial of service is about without permission knocking off service, for example through crashing the whole system. Another definition is that denial of service is seeing to that someone don't get what they paid for. The Network Denial of service Attack Detection System designed and implemented through suggested algorithm can detect attacking from the outside among denial of service attacks. It shown that designed system gives the system administrator the opportunity to detect denial of service attack.

This paper proposes the hybrid heuristic method to apply the opportunity time to solve the vehicle routing and scheduling problem with time constraints(VRSPTW). The opportunity time indicates the idle time which remains after the vehicle performs the unloading service required by each customer's node. In this proposed heuristic, we add the constraints to VRSPTW model for the opportunity time. We also obtain the initial solution by applying the cost evaluation function to the insertion strategy considering the opportunity time. In addition, we improve the former result by applying the opportunity time to the tabu search strategy by swapping the customer's node. Finally, we suggest the construction strategies of initial routing which can efficiently acquire the nearest optimal solution from various types of data in terms of geographical condition, scheduling horizon and vehicle capacity. Our experiment show that our heuristic can get the nearest optimal solution more efficiently than the Solomon's I1 heuristic.

This study analyzes the amendment history of Educare Law of Infants and Children, the Equal Employment Opportunity Law, and Employment Insurance Law, and also examines the present status of the employer-supported child care service through secondary analysis of other policy studies. The three laws concerning employer-supported child care can be said to hold in itself two main concepts: employers' obligations to provide child care, and government's financial support and administrative management. In terms of the first concept, laws have been amended to enlarge the number of enterprises legally-responsible for child care service and to relieve the financial burden from them. In terms of the second, laws have been amended to gradually extend the magnitude of government's financial support and to establish the systematic administrative management. Approximately a half of the policy target enterprises, however, is not complying the laws. In addition, employer-supported child care centers are only occupying less than 1% of the whole child care market. Thus, this study evaluates the current employer-supported child care service system and suggests several principles for its improvement.

With the advent of electric power systems moving from a vertically integrated structure to a deregulated environment, calculating reactive power service charges has become a new and challenging theme for market operators. This paper examines various methods for reactive power management adopted throughout various deregulated foreign and domestic markets and then proposes an innovative method to calculate reactive power service charges using a reactive power market in a wholesale electricity market. The reactive power market is operated based on bids from the generating sources and it settles on uniform prices by running the reactive OPF programs of the day-ahead electricity market. The proposed method takes into account recovering not only the costs of installed capacity but also the lost opportunity costs incurred by reducing active power output to increase reactive power production. Based on the result of the reactive OPF program, the generators that produce reactive power within the obligatory range do not make payments whereas the generators producing reactive power beyond the obligatory range receive compensation by the price determined in the market. A numerical sample study is carried out to illustrate the processes and appropriateness of the proposed method.

We, then, try to find the relationships among service quality, customer satisfaction and repurchase intentions. The results of empirical study show that five attributes(responsiveness, empathy, reliability, accuracy and tangible) are identified as key factors of service quality. Customer satisfaction has also significant effect on repurchase intentions.

초고속인터넷은 지상파방송, 케이블 TV, 위성방송에 이어 또 다른 미디어로 부각되기 시 작 하였다. 특히 통신과 방송이 융화되는 환경 하에서 IP-TV 서비스는 통신사업자나 방송사 업자에게 매우 중요한 중심 매체로 등장 되었고, 접속기술, 네트워크 기술, 동영상 압축기술등 기술의 발전은 더 이상 기술적인 요인이 IP-TV 서비스 활성화의 장애 요인으로 작용하지 않게 되었고, 서비스를 위한 장비 및 단말가격의 급격한 가격하락은 사업의 성공 가능성을 더 높여 주게 되었다. IP-TV 서비스는 보다 양질의 멀티미디어 서비스를 원하는 고객의 수요와 신규 고객을 유치하고 가입자를 Lock-in 시키며, 타 통신 사업자의 고객을 자사 고객으로 전환시키고자 하는 차별화 전략의 일환으로 통신사업자들이 적극적으로 도입하고 있다. 특히 망 진화에 따른 차세대 초고속인터넷 서비스 기술인 VDSL이나 Advanced 케이블모뎀을 이용 DVD 급 고화질의 IP-TV 서비스가 시작되면서 ARPU를 증대 시키고 다양한 수익원 개발의 일환으로 인터넷 접속서비스 외에 부가가치를 창출 할 수 있는 Killer Service로서 주목을 받고 있다. IP-TV 서비스는 가입자망의 진화 와 밀접하게 연관되어 전개되는 서비스로 Post-ADSL에 대한 예측과 IP-TV 서비스에 대한 설문조사 결과를 토대로 하여 예측 한 바에 의하면 Post-ADSL 가입자는 2005년 300만 명에서 2006년 480만으로 증가하고 2009년 1,024만 명에 이를 것으로 전망되고, IP-TV 서비스 가입자도 2005년 36만 명에서 2006년 88만으로 증가하고 2009년 382만 명으로 증가하는 것으로 예측되었다.
