        The need for an intelligent information-based ship accident prevention and control system for various marine accidents is very clearly emerging. As it is a variety of marine accidents, the causes are diverse. Therefore, it can be said that it is very important to prevent these marine accidents and their causes in advance. Therefore, a study was conducted on an intelligent information-based ship safety management decision support system that provides information necessary for decision-making at sea and land through an integrated management device for ships that informs safety-related risks in real-time ship operation. In the future, we intend to pursue the development of a system that can aim for safer and more economical ship operation by linking it to navigation instruments through the evaluation and analysis of AI, IoT, and big data.

        This study tried to suggest a systematic improvement plan to prepare a civil safety insurance operation and management system by reviewing the operation and management status of civil safety insurance, which is operated and managed by each local government autonomously. In this study, the problems of the current civil safety insurance were analyzed by dividing them into the lack of systematic management of insurance items, overlapping coverage between insurance items, and deviations in compensation limits. As a systematic improvement plan, it was suggested to secure the systemic management of guarantee items, standardize compensation standards, prepare an integrated operation and management system, and provide financial support for local governments with poor financial independence. Since the problems and improvement plans for the civil safety insurance analyzed as described above are formed by exchanging and receiving a complex mutual influence, the institutional improvement plan for the operation and management system of the civil safety insurance is not only a specific part of the study, but also comprehensively current citizens. Based on the results derived from the analysis of safety insurance, it is concluded that alternatives must be found.

        최근 건설시장에 4차 산업혁명기술의 급속한 확산과 도입, 적용이 트랜드로 부각되고 있다. BIM 기술은 4차 산업혁명 기술의 근간을 이루는 다차원 정보체계이다. 이러한 정보기반체계를 활용한 하천분야도 유지관리를 위한 현행화 방안 등 적극적인 연구검토가 되고 있다. 최근 하천 전문가들의 하천분야 BIM도입 효과에 필요성을 반영하여 적극적인 연구와 현행화 작업을 해야 된다. 그리고 첨단기술을 반영한 시설물 유지관리 정보체계를 활성화하고 관리계획 수립 및 운영을 위해서는 다양한 정보체계를 구축하기 위한 도구 및 지원소프트웨어의 개발이 반드시 필요할 것으로 전망된다. 하천시설의 유지운영을 위한 연구로 기본적으로 기존 도면자료를 이용하여 3차원 정보모델을 구축하고 이를 활용한 손상을 점검하고 정보화하며 보수보강을 위한 자료로 활용토록 하는 것이다. 이는 기존 도면방식에 없는 정보체계를 하천시설물을 3D 모델링과 함께 유지관리정보를 속성으로 구축하는 방법을 연구하여 유지운영을 위한 점검, 손상 관리를 보다 효과적이고 활용성이 높은 관리방안을 제시하고자 하였다.

        Total organic carbon (TOC) will replace chemical oxygen demand (CODMn) as an effluent water quality standard in public sewage treatment works (PSTWs) from 2021 in Korea. To ensure effective control of TOC in the effluent, investigation was carried out into TOC levels and sewage treatment operation factors in five target PSTWs using anaerobic-anoxic-aerobic (A2O) processes, media, membrane, and sequencing batch reactor (SBR) technologies. TOC removal efficiencies appeared to be 93-96% on average. As a fraction of TOC, biodegradable dissolved organic carbon (BDOC) was reduced from 64% in the influent to 9% in the effluent in these PSTWs. During the investigation, biological treatment processes were applied flexibly for operation factors such as HRT, SRT, MLSS, F/M ratios and BOD volume loads, based on the influent characteristics and design conditions. As a result, we suggest efficient operating conditions in PSTWs by evaluating relationships between TOC removal and operation factors.

        본 연구는 외부 관광객이 많은 인천광역시 월미공원을 대상으로 지역주민과 외부 관광객 사이의 공원 운영과 관리에 대한 인식 차이를 조사 분석함으로써 공원 이용 활성화와 효과적인 운영관리 방안을 모색하기 위해 수행되었다. 자료 수집은 2009년 5월 1일부터 4일간 총 222명의 공원 방문객을 대상으로 현지설문조사를 통해 이루어졌다. 조사결과, 방문횟수 및 목적, 보완 시설물 등에서 지역주민과 외부 관광객 간 차이를 보였으며, 두 집단 모두 인근 관광지에 대한 인식이 공원 이용만족도에 영향을 미치는 것으로 인식함에 따라 공원 구역 내뿐만 아니라 주변지역의 운영 관리에도 만전을 기해야 할 것이다.

        With the foundation of the WTO in 1995, the era of boundless and unlimited competition between many of the countries around the world has begun. In order to elevate the competitiveness in the international market, we have incorporated the QMS and the EMS system, establish by the International Standardization Organization, and the process has been operated under the authorization. However, many Korea companies' separate enforcement of the QMS and the EMS system is causing the dissipation of the labor force and the invested capital. As we can see through studying the contents on this paper, the number of documents has been reduced down to 54% (From 139 of them to 64 of them), and the conflict and the chaos that could have happened between the documents has been prevented. Its' outcome is attributed to the foundation and the embarkation on the Integrated Management Systems of the KS, QMS, and EMS. Not only that, it has also reduced the waste elements up to greater than 40%.

        DESIGNIN AND OPERATION OF DIGITAL EVIDENCE MANAGEMENT SYSTEM APPLYING COMPUTER FORENSICS AND ELECTRONIC CERTIFICATION Digital evidence will be used as a term, which means the electronic form of information which is necessary to confirm or prove the factum of all kinds of behaviors committed through the devices which have data processing ability including computer. It is expected that there will be the increase of legal conflicts surrounding electronic commerce activities as well as the increase of cyber crimes, as the number of Internet users are getting bigger. In order to solve the problems of conflicts derived from electronic commerce, the factum of electronic commerce activities must be confirmed. In order to confirm the factum of electronic commerce activities, the evidence is prerequisite. Almost all evidences relating to the electronic commerce activities exist in digital form. For the reason that the digital evidence can be easily damaged and changed, special management is required to collect, analyze, and preserve the digital evidence. In order to meet this requirement, this study proposes a basic model of digital evidence management system applying computer forensics and electronic authentication.

        The purposes of this study were to : (a) investigate overall operating conditions of university residence hall foodservice, (b) compare them by the management systems. Questionnaires were hand delivered and mailed to 73 foodservice managers. A total of 56 were usable; resulting in 76.7% response rate. The survey was conducted between October, 1998 and May, 1999. Statistical data analysis was completed using the SAS/Win 6.12 for Descriptive Analysis, 2-test. Sixty-four percent of the foodservice operations were 'self-operated'; 23% were 'contracted'; and 13% were 'rented'. Eighty-three percent of operations provided 'single menu'; forty-six percent of foodservice operations with 'partially self-service'; and forty-one percent with 'complete self-service'. Forty-four percent of overall foodservice operations provided 1,000-2,000 meals per day; thirty-one percent provided less than 1,000 meals per day, and twenty-four percent provided more than 2,000 meals per day. The highest meal price was 1,950 won and the lowest was 700 won with average of 1,295 won. The mean number of employees was 12.2; the number of working hours was 59.7 hours per week.
