The purpose of this study is to investigate the problem on safety and health training system in Occupational Safety and Health Act(OSHA) and to find countermeasures to improve it in the construction industry. The questionary survey was done on aiming at tracing the legal drawbacks of safety and health training system. The questionary was prepared to target on site workers, management supervisors, and safety supervisors in various construction sites. After analyzing the answers from the survey, realistic and optimal countermeasures on derived problems were proposed. These should be included on the next revision of OSHA.

Recently fluoridation has often been considered as a method to maintain the concentration of fluoride in the drinking water at level adequate to be able to help protect children having decayed teeth. The benefits of fluoridation can be verified to compare the occurance rates of decayed tooth in the areas fluoridated and not fluoridated. Jainhae and Chongju have already fluoridaed the drinking water, and it was known that fluoridation could protect tooth-decaying effectively. The reduction rate of decayed teeth was estimated to be about 50~60 per cent. In the present study, a questionary survey to about sixty four hundred inhabitants of Taejon was carried out to grasp the opinions of citizens for fluoridation. According to the results, 75 per cent of the respondents agreed to the fluoridation. About 49 per cent and 44 per cent of them wanted that the fluoridation should be enforced after a questionary survey and after the decision of a specialist group in the institutes concerned respectively. About 71 per cent of them agreed to 5 per cent-rising of water fee for the fluoridation. The anual cost reguired for fluoridation in a large city was estimated to be about 500 won per capital therefore its economic effect is very large.

Number of duck and its breeding facilities have been steadily decreasing for financial and social issues in Korea. Therefore, the 'turning point' for duck industry is strongly demanded. In this study, the questionary survey was carried out to provide backgrounds for developing policy and technology for duck breeding farms. The questionary survey aimed to investigate the information of operation strategy of farm, ventilation, cooling and heating. The total number of survey respondents was 74. In case of facility type, 55.4% of respondents stated they used greenhouse type, 31.3% for winch-curtain type, and 2.7% for windowless type (mechanically ventilated facility). More than 85% of the facilities were using 'natural ventilation', it meant that these situation can restrict the not only environmental control but also the supply policy for 'smart farm' of the Government. 44.6% used the combination of the cross-ventilation method and roof-ventilation method for ventilation operation in summer season, and 31.1% followed only the cross-ventilation method. In case of winter season, 36.5% used the cross-ventilation method, and 33.3% used the combination of cross and roof-ventilation, method. For the ventilation strategy, about 86.5% depended on farmer's experience. In case of heating and cooling, 79.7% were using kerosene heater for winter season, and 43.2% were using mist-spray for summer season, respectively. More than 75% stated that cooling and heating strategies were based on farmer's experience. From the analyses of the survey results, a few proposals for developing policy and technology for duck breeding farm was suggested.

This paper makes a trial to build the model of car-following in the state of starting to stable driving on the basic of driver's knowledge that is easily characterized by linguistical cognition. There are three main steps in building the model. Firstly, each driver's rule of three testees is studied in linguistical experssion by the interview and questionary surveys that are repeated once a day for ten days. Secondly, quantification of the linguistical expression is investigated by driving experiments that includes the questionary survey to the testee in the test vehicle, and the membership functions of variables of rule are obtained. Thirdly, implicaton and composition of fuzzy inference is made by Max-Min Methods and defuzzification by gravity method. It can be said that the proposed model of car-following based on driver's knowledge is practically allpicable to the estimation of drivering of car-following on trunk roads in urban area.

The Major inspection is a ship inspection which is executed voluntarily for tankers by Major oil companies(hereinafter it is called "Major").

Thus, even though Major inspection is executed voluntarily, it is more important one than any other inspection for ship's crews and owner because it is closely related to the business profit of shipping company. In this study, authors suggested the improving measures after checking the problems concerned with Major inspection through status analysis. For the status analysis, authors carried out a questionary survey and interview with the interested parties, such as tanker crews, persons in charge of shipping company and inspectors, as well as studied the related literature and statistics data.

A questionary survey was conducted to investigate citizen's attitude to treatment facilities of municipal solid waste in Miryang during 8. June of 1998 and 22 June of 1988. Collection effiencies was 86.7%, as 260 individuals of the 300 individuals. The survey showed that 43.0% of answers recognized seriousness of problem of the waste treatment and 33.1% of respondents concerned about recycle of organic waste. 40.8% of total answers said that they most hated landfill site among waste treatment facilities, and most citizens wanted as much distant as possible from waste treatment facilities. It was investigated that the greater part of respondents wanted the greatest compensation. About 58% of respondents was opposed to complete waste treatment facilities. 36.2$ among answers wanted establishment of waste treatment facilities in an industrial complex or an industrial area. The majority of respondents was willing to increase recycle rate and recognized seriousness of landfill site security.

In this research a questionary survey was implemented to investigate how elementary school students in $3^{rd}-6^{th}$ grade understood articles or terminology using electromagnetic wave technology in contemporary culture. Also, part of students who had participated in questionnaire survey was interviewed 2 times for each 20 minute personally to investigate students＇ perceptions about some household articles in their every day life using electromagnetic wave technology. As a result, first, elementary school students had pretty higher perceptions of the artificial satellite provided in their curriculum and the technology of electromagnetic wave released from cartoons, computer games or advertisements. Second, because they were concerned about appearances of household articles, they perceived some household articles in their every day life with conceptions of electricity or visual mechanism.

This research was conducted to suggest a policy plan for intensive major course in recurrent education system of KNAC. A survey was answered by students, graduates, field professors and (full-time) professors. The results are summarized as follows; 1. In the item of educational operation system, there were some differences in preference among 4 examinee groups. Students preferred 'semester system', graduates and field professors did 'once per week system', and professors 'cyber+centralized training system'. 2. As entering time, students and graduates preferred 'immediately after graduation'. However, field and full-time professors preferred '1 to 3 years after graduation' that became reality. 3. As board and lodging, all examinee groups wanted 'dormitory in college'. Students and graduates were open to pay educational expenses as a level of national colleges. 4. As a curriculum, the most preferred subject by all groups was 'major field technique', which was followed by 'marketing/sale' and 'farm management' in the order of preference.
