The purpose of this study was to examine the differences of self-confidence and satisfaction level in teaching home economics between home economics majored teachers(HET) and other subject majored teachers(OST). The subjects of this study were 192 home economics teachers randomly selected from 96 middle schools all over the country. The data was collected from 16, september to 12, October, 1996, and was analyzed with descriptive statistics, crosstables, and t-test using SAS program. The major finding were as follows: 1) In general, home econimics is taught mostly by OST in boy' middle school. 92% of OST is employed in boy' middle school and 89.13% of them is employed in private boy' middle school. 2) OST had less in-service experiences than HET on sixth revised curriculum, and had lower recognition than HET on the goal, content, teaching method, evaluation of home economics. 3) There were significant difference on the level of self-confidence and satisfaction in teaching home economics between HET and OST.

Railway noise barrier is generally used with welding of joint rail for railway noise reduction in our country. In this study, method for performance evaluation of railway noise barrier using insertion loss was suggested in case of without having noise measurement results before barrier installation. For this, railway noise measurements were performed in commercial high-speed railway site which has railway noise barrier. As a noise level before noise barrier installation, predicted noise level were used. From this method the performance evaluation for railway noise barrier were performed accurately and efficiently.

FFU are used increasingly by the microeleceronics industry to provide clean recirculating air for the fabrication of integrated circuits and laminar flow air. There may be several hundred ffu in a large cleanroom, covering 100% of the ceiling area. Hence, there is of often knowledge in the inside and outside of the country the flu give rise to noise & vibration trouble to microelectronics industry. Noise ＆ Vibration control for satisfication about noise ＆ vibration criteria in TFT-LCD factory cleanroom be in need of exact noise & vibration data of accurence from utility & equipment that can be exert a bad influence upon cleanroom. In this pater, hence we found out noise and vibration properities of ffu by using experimental method. And, we performed noise ＆ vibration analysis about noise it vibration level in cleanroom using semiempirical method for quantative approach about noise ＆ vibration level in cleanroom.

This paper presents how Digital Knowledge Ecosystem such as "Govi Nena" (translates as agriculture intelligence) can be used to provide a more effective and practical solution to eliminate the inefficiencies in agricultural markets and achieve higher productivity and price stability. In order to establish the framework to analyze the system, this paper uses a set of hypothetical scenarios faced by value chain actors based on a review of the literature, established knowledge and recent developing country experiences. The scenario analysis reveals that "Govi Nena" enables farmers to make effective production decisions, deepens the level of value chain integration, and enhances the level of welfare for the society as a whole.

One of the prerequisites for the improvement of the teaching of mathematics in our country is an improved curriculum-one which takes account of the increasing use of mathematics in science and technology and in other areas of knowledge and at the same time one which reflects recent advances in mathematics itself. In the new curriculum of mathematics, we have found the problems to teach the concept of sets at secondary level. The idea of a set is the most fundamental one in mathematics. So, this thesis contains the studies of the systematic analysis of sets in dealing with the traditional textbook. The scope of the work is limited to the fundamental ideas, and so it merely touches on the topics of the Concpets, Operations, Cardinal Numbers, Application of Logic, one-to-one Correspondence, Probability and so on. It provides only the essentials, definitions, proofs and some example which are already known and understood in their traditional context. It also presents at the appropriate stages the concepts required (illustrated by examples) in a much clearer fashion than classical teaching does. To compete a study of the sets covered in the textbook of each year, greater detail is needed at the appropriate level.

Environmental monitoring program is investigated based on Atomic Energy Law and foreign country radiation monitoring programs on low-and intermediate level radioactive waste disposal site. It is anticipated that the number of radiation measurements and samples will be higher than those of NPP's. The radiation monitoring program on LLW disposal site should be well prepared reflecting PA, site characteristics and regulation.

This study is a measurement of effectiveness to a job process for the hospital information system (HIS) used in the hospital industry. Using the effectiveness scale that I developed in the questionnaire of the ISO9241-11 quality model, I measured the importance level of HIS and its significance on a job practices in the large general hospitals within the country. The questionnaire showed that the importance level of domestic HISs was highest in the system used by staffs(mean=3) and to reduce a job process and increase the efficiency of work.

E.U(Europe Union) and I.S.O(International Standard Organization) have promoted environmental problems from an individual enterprise level to international level. E.U have practiced E.M.A.S(Environment Management Audit Scheme), they have explained environmental information to local residents by an environmental statement and they have introduced verification system by identification person. One year later, I.S.O have published ISO 14000 series by environmental audit in 1996. Modem enterprise must go well with profitability and sociality. Environmental accounting was appeared in order to agree with profitability and sociality. Environmental accounting is to solve environmental problems, to protect natural resources, to measure effect of environment, and to transmit information of environment. Accountability's theory must be based social fairness and systemic legality. We need the accountability in order to system of Environmental accounting. But the conception of environmental accounting and accountability are not defined in our country. Therefore the purpose of this study is to established the relation of environmental accounting and accountability.

The Geumsan is contiguous to Daejeon and population is decreasing every year. Consequently, the population influx, and securing source of revenue dimensional geographic and environmental benefits of the establishment of a pensions plan for the rural life style pensions research. The result is that Geumsan has a convenient traffic circumstance geographically and is a clean area as the high-level area of solid water system. Also, Geumsan forms the mountainous area whose sea-level elevation reaches to 2.5 times of the Chungcheongnam-do. Consequently, Geumsan has a suitable environment for locating many kinds of pensions like the riverside village style, the mountain village style and the villa style, the country style, the cafe style, experience style, theme style etc. So, Geumsan is found to be a suitable area to host 'rural life style' pensions, because it has wide area, small population and nice environmental conditions.
