웹을 이용한 클라이언트-서버 데이타베이스 시스템은 웹의 서비스 능력과 데이타베이스 시스템의 데이타 관리 기능을 상호 보완적으로 통합함으로써 인터넷과 같은 대규모 환경에서 데이타베이스 업무 환경을 구축하는 데 매우 적합한 것으로 알려져 있다. 데이타베이스 통로는 이러한 통합의 가장 핵심적 구성 요소이다. 본 논문에서는 먼저 클라이언트-서버 데이타베이스 응용을 위한 데이타베이스 통로의 고려사항으로서, 고성능 실행구조, 응용 프로그램 개발 환경, 그리고 상태 및 트랜잭션 관리에 대해 기술하고, 이어서 UniSQL/X용 데이타베이스 통로인 UniWeb 2.0의 설계와 구현에 대하여 소개한다. UniWeb 2.0은 CGI 응용 서버 방식을 채택하여 다양한 플랫폼을 지원하고, 고성능 그리고 확장성을 제공한다. 또한 프로그래머가 HTML 문서에 SQL/X문장이 포함된 Tcl 스크립트를 끼워 넣을 수 있도록 하여 응용 프로그램 개발 생산성을 향상시키고 있다. UniWeb 2.0은 여러 웹 페이지에 걸친 상태 와 트랜잭션을 지원하고 있다.

채팅을 이용, 이성교제를 하고 있는 네티즌이라면 채팅의 깊은 뜻을 제대로 파악하고 있을 것이다. 그렇다고 채팅이 꼭 유희만을 위한 것은 아니다. 기존의 각종 동호회에게 채팅은 친목도모의 중요한 방법으로 정착되었고, 전화를 대신하는 매체로의 이용도 가능하다. 또 업무상 간단한 정보를 주고받고, 회의의 한 방법으로 사용말 수도 있게 되었는데 본 논문에 다뤄질 "사이버 러브" 시스템은 기존의 단순한 텍스트 위주의 대화식 채팅 시스템이 아닌 새로운 캐릭터를 이용한 이 채팅 시스템은 이용자가 서로 사이버 캐릭터를 이용하여 가상 공간에서의 만남을 갖도록 해주며 최상의 음성 전송을 통해 대화를 주고받을 수 있도록 하고, 각종 이벤트를 통해 재미를 주어 쉽게 이용할 수 있도록 하였다. 또한 가상공간을 상품화 하여 특정 업체를 홍보함으로써 광고수익 효과를 누리고자 한다.

This study was conducted to determine the association between quality of sleep (QOL) and the general characteristics, the health-behavioral factors, and the occupational characteristics of firefighting officers. The survey was conducted in October 2016 with a self-administered questionnaire using the Pittsburgh Sleep Quality Index (PSQI) developed by Pittsburgh University, targeting 600 male firefighting officers working at five fire stations in D city. As a result, the QOL of the study subjects measured by the PSQI revealed 13.2% to be good, and 86.8% to be poor. In relation to general characteristics and health habits, the rate of the group who had poor quality sleep was significantly higher in those with a lower subjective health status, in the non-smoking group, and in the low sleep-quality group, compared to the good sleep-quality group. For occupational characteristics, the rate of those with poor quality sleep was significantly higher in groups such as the fire suppression group, the shift work group, the hard physical labor group, the group with a lower sense of satisfaction in their work, and in the group classed as unfit for the job but who were not considering quitting their jobs, compared to their respective counterparts. Multiple regression analysis revealed factors of influence with explanatory powers of 24.4% for subjective health status, alcohol use, subjective quality of sleep, career, job position, and physical labor. The results of this study suggest that the quality of sleep for firefighting officers is significantly related to general characteristics, health-behavioral characteristics, and occupational characteristics.

The aim of this paper is to extend the TOPSIS(Technique for Order Preference by Similarity to Ideal Solution) to the fuzzy environment for solving the disaster recovery priority decision problem in credit bureau business information system. In this paper, the rating of each information systems and the weight of each criterion are described by linguistic terms which can be expressed in trapezoidal fuzzy numbers. Then, a vertex method is proposed to calculate the distance between two trapezoidal fuzzy numbers. According to the concept of the TOPSIS, a closeness coefficient is defined to determine the ranking order of all information systems. The combination between the fuzzy set and TOPSIS brings several benefits when compared with other approaches, such that the fuzzy TOPSIS require few fuzzy judgements to parameterization, which contributes to the agility of the decision process, it does not limit the number of alternatives simultaneously evaluated, and it does not cause the ranking reversal problem when a new alternative is included in the evaluation process. This paper is demonstrated with a real case study of a credit rating agency involving 9 evaluation criteria and 9 credit bureau business information systems assessed by 6 evaluators, and provide the systematic disaster recovery framework for BCP(Business Continuity Planning) to practitioner. Finally, this paper show that the procedure of the proposed fuzzy TOPSIS method is well suited as a decision-making tool for the disaster recovery priority decision problem in credit bureau business information system.

CM services have been increasingly practiced over the two decades in the Korean construction industry, and recent efforts focus on further development in advanced CM capabilities and expansion to overseas market. However, there has been lack of holistic research to investigate current status and future direction of CM industry in Korea. In this context, the purposes of this study are 1) to analyze current status of Korean CM industry in terms of owners, market, CM firms, contracts, and work scopes, 2) to define different types of CM practices, and 3) to propose growth models for Korean CM firms based on the defined CM project types. An extensive literature review and statistical analysis of 2012 CM contracts were performed in order to analyze the CM status. Based on the analyses, ten different CM types are defined, and growth paths of CM firms are illustrated. Implications and lessons learned during the statistical analysis and workshops are briefly introduced as well.

The aim of this study is to evaluate quality of the bibliographic records for DVDs owned by the domestic university libraries and to suggest how to improve the problems as a result of the evaluation. In order to conduct this study, the previous studies related to the topic were analyzed, and then, four regions of quality evaluation standard including accuracy of inputting, observance of regulations related to cataloging, perfection of expressions and consistency of structure were established. And the quality evaluation was made on total 100 records of the lists for DVDs from 10 university libraries. As a result, several types of errors were discovered in the quality evaluation and some solutions were suggested to improve quality of cataloging records for DVDs by interviewing with catalogers in the domestic university libraries.

The construction industry in Korea has seen significant improvements in quality management techniques, driven by the dramatic development of new technology through Manhattanization and enlargements, but compared with technical development, the level of building quality improvement is still lagging behind. In the meantime, as the interest in construction quality soars due to changes in user consciousness, the level of quality that is being demanded is rising. The government has reinforced quality systems by implementing responsible supervision requirements and granting overseas companies permission to enter the supervision business in Korea, and private sector companies also are attempting quality improvement through quality assurance approaches like the preliminary qualification screening system and ISO 9000 series. But currently, building constructions are done only according to the construction specifications of project owners, whose design, materials and construction methods are already decided, and do not leave any necessity or opportunity for technical developments for the quality improvement of contractors. Therefore, in this study, a work process and system improvement plan for payment regulations is proposed, with which contractors can secure quality voluntarily in the building construction phase.
