As people make efforts on accident prevention, the number of accidents has decreased over the years, however the number of fatal major industry accidents has rather increased, which resulted in the increase of the number of deaths in total. Under these conditions, there is an attempt to introduce and perform the safety vocational education system as a means for preventing major industry accidents. Therefore, in this paper, we analyse vocational education of manufacturing industry from the safety's point of view and suggest the efficient techniques measuring and managing each safety management. Proposed techniques show that the specification on safety determines weight through the managers of firms and each process is suggested by using SN ratio.

In manufacturing industry of the modem industrial society, people increasingly become concerned the awareness of safety increasingly although they have regarded production the most important factor. Even though, as people make efforts on accident preventions, the number of accidents is decreasing, fatal major industry accidents are rather thanincreasing so that the number of deaths has not decreased. Under these conditions, there is an attempt to introduce and perform the process safety management system as a means for keeping from major industry accidents. However, it leaves to be desired on the methods of measuring process safety in the general manufacturing industry, while it is available to do that in the chemistry industry. Therefore, in this paper, we analysis processes of manufacturing industry in safety point of view and suggest the technique efficiently measuring and managing each process. Proposed the technique shows that the specification on safety determines AHP weight through the managers of firms and each process is suggested by using normalized matrix.

This study aims to analyze the influence of psychological capital on organizational performance and to verify the moderating effect of emotional intelligence and the mediating effect of positive mood. The results of an analysis are as follows: First, the influence of psychological capital is higher in job satisfaction than in OCB. Second, the moderating effect of emotional intelligence is recognized in psychological capital and organizational performance. In particular, job satisfaction shows a higher moderating effect than OCB does. Third, no direct effect of psychological capital on OCB is recognized while an indirect effect of psychological capital on OCB through positive mood is recognized. Thus, it is judged that the results of this study would be effectively utilized as a means of motivation for growing individuals and achieving organizations'goals by emphasizing the importance of psychological capital and psychology and systematically managing psychological phenomena according to individual differences.

Due to the rapid growth of Internet, means of communication with customers in a traditional customer support environment such as telephone calls are being replaced by mainly e-mail in a Web-based customer support system. Although such a Web-based support is efficient and promises potential benefits for firms, including reduced transaction costs, reduced time, and high quality of support, there are some difficulties associated with responding to many types of customer's inbound e-mails appropriately. As many types of e-mail are received, considerable attention is being paid to methods for increasing the efficiency of managing and responding e-mails. This research proposes an intelligent system for managing customer's inbound e-mails in organizations by applying case based reasoning technique for responding to various customers' inbound e-mails more effectively. In this approach, a case is represented as a frame-typed data structure corresponding to an inbound e-mail, keywords, and its reply e-mail. In the retrieval procedure, keywords and affinity set is developed to index a case, and then the case is represented as a vector, a case vector. Also, cosines value is calculated to measure the similarity between a new inbound e-mail and the cases in the case base. In the adaptation procedure, we provide several adaptation strategies to adapt and modify the retrieved case. The strategies guide to make an outbound e-mail using product databases, databases for customer support, etc. Additionally, the Web-based system architecture is proposed to implement our methodology. The proposed methodology and system will be helpful for developing more efficient Web-based customer support.

본 논문에서는 마케팅에서 주로 적용되는 CRM(Customer Relationship Management)의 군집분석 방법을 활용하여 콘텐츠 서비스를 이용하는 고객들을 서비스 패턴에 따라 세분화(Segmentation)하고, 군집별로 미디어 서버의 자원을 차별적으로 할당하여, 기업의 수익성을 높이기 위한 새로운 정책을 제시하였다. 새로운 서비스 정책의 구현을 위해 첫째, 고객 데이터에 대해 군집분석 중에서 K Means Method를 적용하여 고객들의 서비스 패턴 (총 사이트 방문 횟수, 서비스 종류, 서비스 이용 기간, 지불금액, 평균 서비스 시간, 사이트 방문 당 서비스 요금)과 수익에 대한 기석도 둥을 분석하였다. 고객들은 수익에 대한 기여도에 따라 4개의 군집으로 분류되었다. 둘째, 군집별로 미디어 서버 자원을 할당하는 알고리즘인 CRFA(Client Request Filtering Algorithm)를 제시하였다. CRFA 는 고객이 속한 군집의 자원 한도 내에서 승인제어를 실시하는 기능을 수행하였다. 분석된 결과에 의하면 CRFA를 적용하였을 때 기업의 네트워크 비용은 감소하고 기업의 수익에 기여도가 높은 군집에 속한 고객들의 수락률이 높아졌음을 알 수 있었다.

오늘날 이메일은 사회적으로 널리 사용되는 보편적인 통신수단이 되었다. 공공기관에서 기관 내 의견 교환은 물론 외국과의 교류와 통상문제, 타 기관이나 기업, 단체 등과의 관계에서 중요한 통신 수단으로 쓰이고 있다. 또한 전자 정부를 지향하는 추세에서 이메일은 국민과 접촉하는 일차적인 수단이 되고 있다. 그러나 우리나라는 아직 이메일을 공식적인 기록으로 인정하고 있지 않고 이메일 관리를 위한 어떤 지침도 제공하고 있지 않다. 이메일은 전자 기록의 한 형태이며 공공 업무를 위해 사용되었다면 기록으로서 획득되고 관리되어야 하고, 획득 관리하기 위해서는 필요한 메타데이터 요소를 규정하는 것이 필수적이다. 따라서 본고의 최종적인 목적은 이메일 기록의 획득 시 확보해야할 메타데이터 요소를 제안함으로써 우리나라 이메일 기록관리의 기초를 제공하는데 있다.

This study seeks to identify elements of spatial planning for areas surrounding children's parks in order to improve child safety. It will identify different aspects of child safety and extract elements of safety planning for the areas surrounding children's parks from a literature review of both domestic and international research. The study classifies the space between one's residence and the children's park as either a "means of access", such as pedestrian walkways and streets, or a "boundary", which consists of the entrance, exit, and fences; then, the derived safety planning elements were categorized in accordance with this classification. In order to ensure the validity of the planning elements, an expert survey was conducted of environment planners who specialize in the palnning and designing of residential area as well as government employees who are in direct charge of managing children's parks. The survey findings were as follow. First, the pedestrian walkway(means of access) near the park is the most crucial factor in regards to the safety of children, followed by the entrance and exit(boundary), fency(boundary), and streets (means of access), in descending order of importance. Thus, improving the safety of the pedestrian walkway should be considered first and foremost, and it should precede improving the surrounding streets. Second, an investigation of the need for safety devices near the children's park showed that securing visibility, through the installation of an illegal parking prevention device, is imperative. Illegal parking near children's parks poses a grave risk to pedestrian safety and demands immediate action. Furthermore, a section of streets within 300m of the park entrance should be designated as a children protection zone, in addition to the designation of school zones near elementary schools.

웹 서비스의 활용 범위가 커지고 실제적인 구현사례가 늘어감에 따라, 웹 서비스 품질모델을 현실적으로 적용할 수 있는 방법에 대한 중요성이 커지고 있다. 웹 서비스 품질을 일관성있게 유지하기 위해서는 웹 서비스 품질보증에 대한 방안이 연구되어야만 한다. 웹 서비스 보증이란 웹 서비스의 품질수준을 일정수준이상으로 유지하기 위한 행위들의 총체를 의미하며, 이를 위해 웹 서비스 품질보증자란 새로운 개념의 관계자가 국제기구에서 웹 서비스 표준으로 새롭게 제시되었다. 웹 서비스 품질보증자는 웹 서비스 사용자들의 품질요구사항을 수렴하여, 웹 서비스 제공자가 일정 품질수준이상의 웹 서비스를 제공할 수 있도록 감시한다. 웹 서비스 제공자와 사용자 그리고, 품질보증자는 웹 서비스 수준을 관리하기 위해 서비스 수준을 측정하여 그 결과에 따라 페널티와 인센티브를 부여하는 SLA(Service Level Agreement) 방식을 적용할 수 있다. 하지만, SLA에서는 서비스 사용자와 제공자가 같은 서비스 항목에 대해 일대일로 대응한다는 전제를 가지고 있어서, 다수사용자와 공공성, 그리고 제3자 관리와 같은 웹 서비스 프레임워크에는 적합하지 않은 점들이 존재한다. 따라서, 웹 서비스에 SLA를 적용하기 위해서는 웹 서비스의 이러한 특성들을 반영한 새로운 보증기법이 필요하다. 본 논문에서는 품질 기대수준을 표현하기 위해 웹 서비스 품질 위탁보증수준이라는 새로운 개념을 제시하고자 한다. 이는 각 사용자의 각 품질항목별 품질기대수준의 최대치라 할 수 있으며, 웹 서비스 품질관계자에게 일관성있는 품질 뷰를 제공한다. 본 논문에서는 이를 이용해 각 품질관계자가 보다 쉽게 일정 수준이상의 품질수준을 유지할 수 있는 방안에 대해 제시하고자 한다.
