Along with the rapid emergence of the Internet and e-commerce, online auctions are hitting the spotlights. The inconveniences found in off-line auctions, such as time and place restriction and limited number of items, are solved in the online auction. However, not so many auction sites have integrated auction information systems, which monitor the present status of auctions, resulting in greater inconvenience for the online auction users. Moreover, there is no auction site that suggests the appropriate starting or closing price that is useful for users when they make, their bids, What the online auction users need is an auction system that can solve such problems. This study is purported for solving the problems by designing and implementing a real time auction system that applies the comparison search functions and the agent functions. In other words, an integrated database system using a bidder-oriented agent for providing information is built so that the users can search and compare the information on the item they are interested in and make a faster and more accurate purchase. Also the appropriate starting and closing prices are offered to the sellers and bidders through the integrated system for a closer and more accurate comparison and analysis of the prices. For future work, the product recommendation service, which accurately reflects the bidding patterns, and the methods for studying the multi bidding pattern will be applied to the suggested system to realize a real time auction information system that supports CRM(Customer Relationship Management) .

SOA는 하나의 시스템이 아니며 다양한 서비스를 제공하기 위한 다양한 시스템이 SOA개념 하에 서로 유기적으로 연계되어 있다. 이러한 SOA를 실현하는 미들웨어이며, 분산된 서비스 컴포넌트의 효율적인 통합을 실현하는 ESB는 BPEL 혹은 솔루션 벤더의 자체적인 표준을 따르는 프로세스 매니저와 연동해 프로세스 기반의 통합을 지원한다. 기업 차원에서 볼 때, 안정적인 SOA를 기반으로 BPM을 구축하면 BPM이 보다 민첩하고 유연해지며, 여러 부서와 위치에 걸쳐 BPM을 보다 쉽게 확장할 수 있고, 기본 IT 시스템의 변화에 보다 탄력적으로 대응할 수 있다. 또한, 프로세스에 필요한 일부 서비스를 거래 파트너에 아웃소싱할 수 있고, 회사의 고유한 프로세스를 내외부의 신규 고객에게 서비스로 제공할 수 있는 새로운 비즈니스 모델을 만들 수 있다. 이런 비즈니스 프로세스를 운영하면서 서비스에 대한 품질과 각 프로세스에 대한 관리를 효율적으로 하기 위하여 본 논문에서는 EERP (End to End Resource Planning)을 적용하여 QoS를 보장하고자 한다. EERP는 SO(Service Oriented)-SCM이나 SO-CRM과 같은 엔터프라이즈 환경에서의 내부, 외부의 리소스들을 최적화 하며, 프로세싱에 사용되는 각 리소스들을 실시간으로 감시하며 QoS를 보장하는 매커니즘을 통하여 최적화한다. 이를 기반으로 본 논문에서는 이러한 EERP QoS 구조를 제시한다.

According to the development of service industry recently, the use of call taxi service is increased to use a taxi more comfortably. But related firms hesitate to construct a call center on account of enormous expense of constructing. Hence we developed the system that can minimize expense of constructing a call center which use a cellular phone. The proposed system is different from the existing call system of using a terminal method. we designed by applying UML(Unified Modeling Language) the system that can integrate and manage operations of customer management, driver management, order management and settlement of accounts etc. more efficiently using CTI(Computer Telephony Integration). Then the designed system is constructed by using Visual Basic 6.0. For implementing CTI more effectively, calling number of customer is received in PC using CID that is commercialized and then the customer's information is retrieved in the Database in real-time. The system proposed in this paper is possible to construct at low expense, can improve customer service level through an efficient customer management solution.

Due to the nature of teenage students' common tendency of being drawn to consumption conformity engendered by popular trends, and further expanding their unique collectivist culture, this study presumes that middle and high school female students as well have an influential factor that creates their distinctive trait. This study is intended to investigate the students' personal characteristics and effects of social reference groups, and further scrutinize how these influences transcends to deviant make-up behaviors. A total of 297 subjects, middle and high school female students, participated in a survey, using questionnaires focused primarily on the degrees of color makeup and the influences imposed by classmates. The findings of the study are as follows. First, regarding makeup behavior displayed by middle and high school female students, social self-esteem had positive influence on innovation and peer pressure. Second, perceived visibility conversely had negative impacts on innovation and peer pressure. This indicates that if perceived visibility is at a salient level, this already signifies lack of innovation. Third, makeup innovation and peer pressure demonstrated by middle and high school students all showed positive influence on their makeup behaviors. Additionally, peer pressure, in comparison to innovation, had greater influence on makeup behaviors, which indicates that peer pressure play a great role in makeup behavior of middle and high school students. Fourth, makeup behaviors showed strong impacts on makeup satisfaction and rendering deviant behaviors, which indicates that a new direction and perspective regarding middle and high school students' makeup behavior is critical.

The current research was conducted to examine the factors that affect outsourcing performances, and further investigate whether a discrepancy in performance exists between the medical institutions and hotel service institutions. The study surveyed both medical and hotel administrators for approximately two months, who managed outsourcing tasks. Total of 325 responses out of 350 distributed were collected. However, due to inadequate responses, six responses were excluded, amounting to total of 319 (155 medical institutions, 164 hotels) valid responses included in the final analysis. First, the informal outsourcing relationships between representatives of outsourcing service seekers and providers did not appear to have significant effects in terms of the levels of trust in neither medical institutions nor hotel industries. However, the relationships affected outsourcing degrees exclusively in medical institutions, showing the disparity between the two service institutions. This was explained due to the continuing long term efforts required to establish an informal relationship in medical institutions. Second, communication was shown to have positive effects on levels of trust in both medical institutions and hotel industries. This indicates a prominent outsourcing trait that emphasizes the significance of mutual cordial communication that contributes to establishing positive relationships. Third, opportunistic behavior of the outsourcing service providers appeared to negatively affect the levels of trust as well as outsourcing degrees for both medical and hotel industries. Therefore, opportunistic behaviors were found to have more tendencies to causing tension and discomfort rather than creating a relationship based on mutual credibility or conviviality. Fourth, the effect of service infrastructures on the level of trust did not appear to be significant on medical institutions, while showing positive influence on hotel industries. Additionally, service infrastructures were found to positively influence the outsourcing performance levels for both sectors. Fifth, trust between outsourcing service seekers and providers did not appear to have noticeable impact on the outsourcing degrees for either institution. On the contrary, trust appeared to have positive impacts on performance for both institutions. This further indicates that, when engaging in outsourcing, strengthening relationships through mutual partnership with outsourcing entities rather than establishing contractual relationships leads to improving the reciprocal trust, which in turn improves work results. Lastly the outsourcing degree of service seekers appeared to have positive impact on the outsourcing performance for both medical institutions and hotel industries, indicating the causal relationship between the affectability of outsourcing degrees and the following performance results.

Lately, new influentials have secured a large number of volunteers on social networks due to vitalization of various social media. There has been considerable research on these influential people in social networks but the research has limitations on location information of Location Based Social Network Service(LBSNS). Therefore, the purpose of this study is to propose a spatial detection methodology and application plan for influentials who make comments about diverse social and cultural issues in LBSNS using spatial statistical analysis methods. Twitter was used to collect analysis object data and 168,040 Twitter messages were collected in Seoul over a month-long period. In addition, 'politics,' 'economy,' and 'IT' were set as categories and hot issue keywords as given categories. Therefore, it was possible to come up with an exposure index for searching influentials in respect to hot issue keywords, and exposure index by administrative units of Seoul was calculated through a spatial joint operation. Moreover, an influential index that considers the spatial dependence of the exposure index was drawn to extract information on the influential areas at the top 5% of the influential index and analyze the spatial distribution characteristics and spatial correlation. The experimental results demonstrated that spatial correlation coefficient was relatively high at more than 0.3 in same categories, and correlation coefficient between politics category and economy category was also more than 0.3. On the other hand, correlation coefficient between politics category and IT category was very low at 0.18, and between economy category and IT category was also very weak at 0.15. This study has a significance for materialization of influentials from spatial information perspective, and can be usefully utilized in the field of gCRM in the future.
