The Internet banking service, through which customers process their banking-related works, was introduced in July 1997. The service has since spread quickly, and as of the end of June 2000, just one year after its introduction into Korea, its subscribers numbered 1.23 million people. This figure is ten times larger than the 120,000 subscribers recorded over the six months period up to the end of 1999. In addition, since the end of June 2000, subscriptions on average increase by more than 10,000 a day, and by the end of December 2000, it is expected to pass the 3 million mark. There has been no empirical study conducted on the invigorated Internet banking's status and its services. Therefore, this research is designed to conduct a survey on the Internet banking service status, to conduct actual transactions from the viewpoint of customers and then make a empirical evaluation of it. This will indicate directions for improvement and development of the domestic Internet banking service. We have evaluated ten areas of the Internet banking service including financial service, customers service, users'convenience, and system safety. As of the end of June 2000, 18 out of 20 commercial domestic banks are providing an Internet banking service, and we have conducted evaluations of all these banks. The evaluation is divided into ten categories with 100 points as a maximum score. These are then classified into six grades AAA, AA, A, BBB, BB and B. The outcome of this evaluation was featured in the major domestic journals, and the banks, acknowledging the value of the report, declared that they would adopt it as their criteria for evaluation.

화재로 인한 인명 피해를 줄이기 위해, 화재 대피용 방연마스크에 대한 관심과 보급이 증가하고 있다. 하지만 시중에 유통되는 방연마스크의 성능 인증 여부와 일반인들이 방연마스크를 적절하게 착용할 수 있는지에 관한 조사가 충분하지 않기 때문에, 방연마스크가 화재 현장에서 피난안전성을 실제로 높일 수 있는지 판단하기가 쉽지 않다. 본 연구는 방연마스크에 대한 일반 사용자의 인식 현황 및 사용 경험을 조사하고, 교육 필요성을 분석하였다. 또한 국내에서 유통 중인 방연마스크 제품들이 국내외 성능 기준에 따라 인증되고 있는지 조사하였다. 아울러 실험을 통해 방연마스크의 착용 신속성 및 활동 편의성을 평가하였다. 235명의 응답자 중 방연마스크를 실제 사용해 본 응답자는 22%에 그치고, 23%는 방연마스크를 모름에도 불구하고, 93%의 응답자는 방연마스크가 화재 피해를 줄일 수 있다고 기대했다. 국내에서 유통 중인 54개의 방연마스크 중 약 41%의 제품이 성능 인증을 받지 않은 것으로 조사 되었다. 국내외 다양한 성능 기준들 중에서 ASTM E 2952 및 KFIS 024만 방연마스크의 착용 신속성을 30초 이내로 규정하고 있다. 그런데 4가지 형태의 방연마스크를 대상으로 착용 신속성을 실험한 결과, 후드형 방연마스크와 자급식 방연마스크는 30초 이내로 착용하기 어려운 것으로 나타났다. 정화식 방연마스크에 비해 자급식 방연마스크를 착용하면, 의사소통의 어려움과 심리적/물리적 불편감을 더 많이 느끼는 것으로 나타났다. 한편, 방연마스크의 착용 교육을 받은 경우, 착용 시간은 약 19%, 오착용 횟수는 약 89% 감소하여, 적절한 착용 교육과 훈련이 매우 중요하다는 것을 확인할 수 있었다.

As there is no case study with current status, measurements or description on the state of actual site of rural area only, the delivery of actual conditions about such an area is significantly limited. The purpose of this study is to pinpoint issues with housing conditions of low-income family with disabled members in the rural area. For such a purpose, 25 households of disabled people have been visited for interview, on-site research and survey, of which results are summed up in this paper as following: First, average monthly income of such family turned out to be KRW 480,000, most of which is from the government subsidy. High ratio of such families has resided in a house with average size of approximately 56m2 for about 24 years. Secondly the most needed maintenance work with top priority was for the toilet, and many of the interviewees expressed their discomfort about small size of their bathrooms and inconvenient facilities therein. Thirdly, most of such houses had too high thresholds that posed danger and inconvenience. Such thresholds had average height of 13cm, which can be considered as completely inconsiderate of disabled users. Fourth issue was that these people needed safety handle that will enable them to stand up or to be in the standing posture in the living room and bedroom where they spend most of their time. Fifthly, they wanted finishing materials with waterproof functionality as well as replacement of finishing materials and wallpaper which were too old and caused hygiene issues. As these issues represent, current housing for disabled people in the rural area turned out to be poor and risky space rather than the place where difficulty of individual situation can be resolved or their disability can be complemented. Thus it can be determined that now is the time to arrange the solutions for such housing difficulties and to establish customized housing plan to ensure safety and convenience.

Maintenance of power distribution facilities is a significant subject in the power supplies. Fault caused by deterioration in power distribution facilities may damage the entire power distribution system. However, current methods of diagnosing power distribution facilities have been manually diagnosed by the human inspector, resulting in continuous pole accidents. In order to improve the existing diagnostic methods, a thermal image analysis model is proposed in this work. Using a thermal image technique in diagnosis field is emerging in the various engineering field due to its non-contact, safe, and highly reliable energy detection technology. Deep learning object detection algorithms are trained with thermal images of a power distribution facility in order to automatically analyze its irregular energy status, hereby efficiently preventing fault of the system. The detected object is diagnosed through a thermal intensity area analysis. The proposed model in this work resulted 82% of accuracy of detecting an actual distribution system by analyzing more than 16,000 images of its thermal images.

In this paper, in order to reduce the electrical disaster such as electrical fire at traditional markets, we need to develop the circuit breaker which is able to monitor the power status of electrical equipments. Therefore, for solving the those problems, we developed the detection censor(ZCT, CT) and equipment of data analysis and transmission. The detection censor and equipment is able to monitor the electrical equipments condition(over current, leakage current, arc, etc.). We constructed Test-Bed for testing reliability of the circuit breaker and obtained certification. And we tested the over current, leakage current and arc under the normal condition. This paper will be used to the data for development an cabinet panel which is able to monitor the actual loads.
