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.

Smoke masks have attracted great interests and have been supplied widely for the improvement of the safety during fire evacuation. However, there is not sufficient research on the practical utility, certification status and easy-donning about commercial smoke masks, therefore it is difficult to determine the actual usefulness of the smoke masks. In this study, we conducted a survey on users' perceptions and experiences about the smoke masks, and investigated the status of certification of 54 commercial smoke masks. We also performed donning tests and examined degrees of discomfort for 4 types of the smoke masks. Although 22% of 235 respondents had experienced the smoke masks before the test, and 23% of the respondents did not know the smoke masks, 93% of the respondents expected that the smoke masks could protect users from fire smokes and toxic gases. It was found that 41% of the commercial smoke masks did not certify according to domestic or overseas performance standards. Most certification standards have not effectively regulated maximum wearing time for the smoke masks. Only ASTM E 2952 and KFIS 024 had specific standards for the maximum wearing time of 30 s. As a result of donning tests for 4 types of smoke masks, the wearing time of the hood-type mask and self-contained smoke mask exceeded 30 s, therefore these types of smoke masks might increase the required safe evacuation time. On the other hand, it was also found that short education about the donning could reduce the wearing time by 19% and numbers of improper wearing by 89%.

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.

The dental accidents and disputes among Korean dentists have been on the increase with time. The main purpose of this study is to figure out the actual status of the dental accidents and malpractice disputes based on a questionnaire survey. The findings showed that 64.8% of respondents had been experienced the dental accidents, and 52.9% of respondents had been locked into the disputes. Within 5 years from the start of dental practice, the nearly half of the dentists responded the experience of the dental accidents and disputes. The amount of compensation for dental accidents and disputes wereindentalimplant, prosthodontics, and oral surgery treatments in descending order. The highest incident type was wrong process/treatment/procedure problem in clinical process/procedure.

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.

The purpose of this study is to establish the training standards for HF of aviation maintenance reflecting the growing relevance of aviation maintenance technicians' ability to perform their work for the safety and efficiency of airline operation. For this purpose, previous studies on the concept of human factors were examined, and the HF training standards of the advanced international aviation bureaus such as the International Civil Aviation Organization(ICAO), Federal Aviation Administration(FAA) and European Aviation Safety Agency(EASA) were compared with the operational technical standards of Korea Aviation Safety Law. In addition, the actual status of human factors education and training were examined for Korea's two full service carriers (FSC) and four of the low cost carriers (LCC). The study results revealed that Korea's human factors education and training standards were weak compared with international standards, and that most airlines were not able to systematically implement human factors education and training. These results complement the existing problem of training standards for aviation maintenance human factors in Korea and support the development of a standard model of the training course for aviation maintenance human factors which meets international standards.

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.
