The present study was designed to be link a part of the research on the investigation on daily life and consciousness of the longevous people in Korea, and to investigate the health conditions, and the attitude on disease and suffering of longevous people in the past. 1. By the health conditions of longevous people between 40 and 60 years, ""very good"" showed the highest figure of 71.0%, followed by ""ordinary"" (21.6%). Consequently it is found that 92.6% of total longevous people surveyed maintained the good health conditions above ordinary. 2. Of the experiences of disease and/or injury after 60 years of longevous people, ""never"" showed the highest figure of 74.7%, while ""had"" showed the only 22.6% of total longevous people surveyed. 3. Of the details of disease and/or injury after 60 years of longevous people. ""digestive disease"" showed the highest figure of 32.6%. followed by ""apoplexia cerebri & hypertensions""(14.0%) and ""heart disease""(14.0%), and followed by ""respiratory disease""(12.3%). 4. Of the experiences of suffering between 40 and 60 years of longevous people, ""never"" showed 53.7% of total longevous people surveyed, while the frequency of suffering decreased in the order of ""once""(22.7%), ""2 times""(15.8%) and ""3 times""(4.7%). By the details of suffering between 40 and 60 years of longevous people. ""family life"" showed the highest figure of 85.1%, followed by ""business""(10.1%). 5.

This study is attempted to analyze the horticultural farm management in the plastic houses by the types of enterprise combination. For this sudy, three horticultural areas were selected, which areas have respectively the different types of enterprise combination with the identical terms of the socioeconomic environment. In three sample areas, 110 house-holds of farming horticultural crop in the plastic film houses are surveyed through interview by farm households. The major findigs of this study are summarized as follows: (1) The majority of farms in sample areas tenanted the paddy land for horticultural crop farming in the plastic film houses, and the size of tenure is less than 0.3ha in which the farms can cultivate horticultural crop with the family labor. (2) The farms in the sample areas have cultivated the horticultural crop for long time. As a result the three selected areas have no difference of technology level of farming horticultural crop in the plastic film houses. (3) There are various types of enterprise combination in the sample areas, which are specialized by individual area as follows: A. In chojeon, to cultivate the cucumber first and the water -melon next, or the sweet melon twice and the water-melon in the vinyl-house. B. In Duckui, to cultivate the green pepper in the vinyl-house. C. In Danmock, to cultivate the cucumber first and the sweet melon next, or the cucumber first and the red pepper for seeds next in the vinyl-house. (4) Horticultural crop farming doesn't repersent economics of scale, where capital can't be substituted for labor, because capital and labor are constantantly inputed per one vinyl-house (150 Pyung) for horticultural crop faming . So the most important factor to determine the farm size of horticultural crop farming is family labor holdigns. (5) The quantity of production resources inputed for horticultural crop farming in the plastic film houses is found to make widely a difference according to the types of enterprise combination and make no difference among three areas. (6) In the case of cultivating only one horticultural crop, horticultural net income has turned out to be negative. So the farms of cultivating horticultural crop in the vinly-houses have various types of enter prise combination in order to ensure their horticultural incoe. It is found that horticultural net income per one viny-house (150 pyung) doesn't increase, although the size of farming horticultural crop increases. It is also found that these farms ensure the horticultural returns to family labpr sufficiently, but that its net income rate is low. (7) The determiant of horticultural farm size is family labor holdings. If they extend the size which can't be cultivated by their family labor holdings, net income decreases because hired labor increases. When they cultivate horticultural crop with man and his wife labor, optimum size is as follows: A: In the case of the green pepper, 6 vinyl-houses can be cultivated. B: In the case of the cucumber first and the water-melon next, or the cucumber first and the sweet melon next,6 vinyl-houses can be cultivated. C: In the case of the cucumber first and the red pepper for seeds next,2 vinyl-houses can be cultivated. D: In the case of the sweet melon twice and the water-melon next, 8 vinyl-houses can be cultivated.

In this paper, the behavior of single and pile groups under lateral load are studied through laboratory experiment. Model piles were made of brass pipe with outer diameters of 28.6mm, which are laid in loose, medium, dense sand of zigzag arrangement. The test results are as follows. As the increasing of relative density, the maximum bending moment is increased. The point of maximum bending moment on single pile measured at 5∼8B(diameter of pile) depth from surface, and group piles measured at 5∼l1B. The bending moment obtained by this experiment similiar with the one obtained by the Chang's theory.

The plant export is as not the export of machinery but machine system bearing technique and know-how. The plant export means export of equipments and techniques in need of materialization of the importers project and maintaining and enlarging the importer's business. Therefore, the plant export is the comprehensive export industry to be composed of the compound factor's, that proves very significant to both sides of importer and exporter from a view point of production method having productive function which is not the raw materials and the ultimate consumer's goods. Therefore, while the plant export has a big value added and an high productive effect, the plant export neccessitate not only the skill of a high order and accumulated experiences but also a large sun of funds. In view of the fact that the plant export have the distinquishing feature above mentioned, the six developed countries which are the united state of America, west Germany, France, Italy, Japan have occupied 70-80% of the world's plant export. Compared with it, Korea's actual records of the plant export are still in significant, in particular, the plant export's ability in fields of engineering and machinary is still in a really early stage. But the Korea's plant export contract amount had been rapidly increased to $877 millions at the end of June,1978 since exporting the textile plant of 1 million to Parkistan in 1973. Though the Korea's plant export is still under insignificant stage, the plant export might be a business with a blight future. This article, firstly, is to inquire into the meanings of plant export, a technical subject, a world's trend and plant expert strategy and supporting policy in the main Developed Countries. Secondly this article has searched the device for improvement of expert through the study of problems which Korean policies of plant export have confronted. A conclusion, writer intended to present the followings for the perspectives of export policy. Firstly, In order to enlarge the productive foundation of plants and to establish the harmonious supply system it needs to aceelate the heavy chemical industrization of domestic industries, and to promote and to specialize the main items of plant industries. Secondly, in order to improve the technology, which is lower than that of the advanced countries, it is necessary to be active in the introctuction of technology and the promotion of manufacturing level of technicians. Thirdly, plant industries being large scope in unit dealings and it's period being lengthy, it needs to enlarge the plant industries, and to specialize and to enlarge the engineering and other soft ware part. Fourthly, it needs the positive export activities through the consolidation and enlargement of supporting system as monetary, tax system and insurance. Finally, it needy the active support of the governmental level as embassies and legations for the strenghening of acceptance competition and the acceptance of large scale projects from foreign states.

이 연구의 목적은 일시적인 서키트 웨이트트레이닝과 일반적인 웨이트트레이닝에 따른 면역 반응의 변화를 분석하여 지질대사를 촉진하면서도 안전한 중량운동의 유형을 규명하는 것이었다. 건강한 20대 남자 대학생 9명을 대상(22.8 ± 2.6세)으로 72시간 이상 공복상태에서 set 사이에 거의 휴식 없이 수행하는 서키트 웨이트트레이닝과 set 사이에 1분의 휴식과 운동기구사이에 3분의 휴식을 취하는 일반적인 웨이트트레이닝을 일시를 달리하여 각각 수행하게 하고 운동전과 운동 직후, 회복기 30분에 각각 10㎖의 혈액을 채취하여 T₃cell, NK cell에 대하여 분석했다. 연구의 결과 서키트 웨이트트레이닝과 일반적인 웨이트트레이닝은 운동 중과 회복기 30분의 면역반응(T₃cell, NK cell)에서 유의한 차이를 보이지 않았다. 하지만 서키트 웨이트트레이닝이 일반적인 웨이트트레이닝보다 면역계에 대한 운동반응에 더 큰 것으로 나타났지만 회복기 30분에는 모두 안정시 수준으로 회복했다. 결론적으로 운동 중과 회복기의 지질대사를 촉진하여 체지방 감소를 촉진하고 골격근의 대사율을 높여서 궁극적으로 비만을 해소하기 위하여 기존의 낮은 강도의 유산소성 운동과 함께 웨이트트레이닝을 실시해야 하는데 서키트 웨이트트레이닝과 일반적인 웨이트트레이닝 모두 안전한 것으로 나타났다. The purpose of this study was to investigate the impact of acute weight training pattern on immune responses. Nine healthy male college students(22.8 ± 2.6yrs) performed circuit weight training without rest and regular weight training with 1 min rest between sets and 2 min rest between exercise machines in different occasion with 12 hr fasting. Blood samples of 10㎖ were drawn at resting, immediately after exercise, and 30 min recovery and analyzed The results of this study was as following. There was no significant differences between circuit weight training and regular weight training in immune responses to exercise. Although the circuit weight training showed somewhat higher immune responses to exercise, the levels of T₃ cell and NK cell in both training methods returned to resting value after 30 min rest. As conclusion, both circuit weight training and regular weight training seemed safe to combine with low intensity aerobic exercise for managing obesity.

韓國 近代 技術敎育에 미친 日本의 影響

金振淳,金秉觀 충남대학교 1992 論文集 Vol.15 No.1

This study investigated Japanese influence upon the modern industrial education during the last Yi Dynasty(1876-1910) and Japan governance period(1910-1945) in Korea. The main findings of the study were summarized as follows: 1) From the year of 1876 to 1910 the government of Yi Dynasty put much effort to start modern industrial education and to train young people to be good technicians and craftsmen. But the effort had not much succeeded, because of the contemptuous thought of practical vocation of people and the influence of foreign countries' power. 2) In the period of Japanese colonial rule. Japanese policy for industrial education forced down the skill grade of industrial manpower of Korea. Their policy was that the Japanese could become engineer and technician through higher education, on the other hand the Korean could become only lower craftsmen through lower education. 3) Especially in 1930's Japanese monopoly capital flowed over to Korea, and the ruling government established vocational schools which trained lower technicians functioning between Japanese capital and Korean labor. 4) After China-Japan War outbroke in 1937, it was difficult to import engineers and technicians from Japan. Therefore a college of engineering was established in 1938, but the fields of education was very limited to mining or machinery sectors. 5) The above mentioned facts had become one of the reason why Korean should be dependent upon Japan in industrial technology.
