The main purpose of these studies was the improvemen of nutritional supply and of the future physical coditions. The two groups which were regional difference were chosen and research for the nutritional status of elementary school students. The nutritional status of lunch-box between one elementary School of 98 students in the 6th year grade(hence-forward it was called "A-Group"), located at the center of Masan City, being provided the milk and the other elementary School of 134 students in the 6th year grade(hence-forward it was called "B-Group"), located in the small farm and fishing villages of Kusan-myun, Euichang-kun, Kyungnam province, were seweyed from the period of Nov. 20, 1986 to Dec. 4, 1986 and conclusion were as follows: 1. Nutritional status of lunch-box 1) It is indicated that in the case of A-Group, the nutirtional intake except animal protein and vitamin A were lower than the Recommended Daily Allowances of Korenas and in the case B-Group, was also lower than except vitamin A respectively and especially in both groups, the percentage of Fe was lowest and intended difference between A Group and B was that B-Group in the intake of calorie, fat, Ca, Fe and etc were lower than A-Group. 2) The total calorie-intake was short of the extent to approx. 83.8% as compared to the RDA. On the viewpoint at ratio of intake of caloric nutrients, A-Group appeared to be 69.5 : 16.5 : 14 and B-Group, 77.5 : 19.5 : 13 in order carbohydrate, protein and fat. As a result of the above ratio, B-Group depended upon carbohydrate as a staple food more than A-Group. It can be considered that the total calorie-intake is short, and that the amount of lunch-box was greatly insufficient for taking optimal nutrition. 3) Calorie, carbohydrate, vitamin B, and niacin were taken nutrition from a staple food and protein from at similar ratio of staple and subsidiary food and fat, Fe, vitamin A, vitamin B1, adn vitamin C were mainly taken from a staple food. It was indicated that B-Group was higher at the supply-ratio by a staple food than A-Group. 3. The realities of improvement of physical conditions The improvement of physical conditions of the two groups were lower in accordance with Korea Children's Growth Standard, but B-Group was inferior to A-Group. 4. Seeing that the total intake of nutrition being taken at lunch time was lower as campared to the RDA intakes between the two Groups were remakably different, a lot of efforts should be made to improve the calorie-intake for the purpose of the farm and fishing villages. For balanced intake of nutrition, selection of foods and various cooking ways are important, therefore, throughout the expansion of the lowest stratum of elementary schools for milk-supply, high-quality protein, fat, Ca, vitamin B2 and etc should be supplied to the growing students. That can narrow the gaps of the intake of nutrition and physical condition between the students who live in cities and the students who live in the country.

전북지역 자동차산업 입지는 1990년대 초반 양적성장단계에 접어든 완성차업체의 저렴한 생산공간 확보전략과 정부의 선도기업 입지에 의한 지역균형발전 개발정책에 의해 이루어졌다. 그 결과 부품산업의 기반 없이 완성차업체가 입지한 후 부품 및 소재업체가 입지하는 반대되는 발전 패턴을 취하고 있기 때문에 취약한 지역산업의 구조적인 문제점을 보이고 있다. 우선, 지역 부품산업의 계층적인 구조가 정립되지 않아 효율적인 분업생산체제를 갖추지 못하여 많은 부품을 외부지역에 의존하고 있다. 그리고 대부분의 부품업체는 특정 완성차업체에 전속되어 있으며, 지역 부품산업의 대부분은 단순 임가공을 필요로 하는 저부가가치 업종으로 이루어져 있다. 마지막으로, 다른 지역에 비해 상대적으로 연관산업의 집적도가 낮아 기업유치 경쟁력이 낮은 문제점 등을 가지고 있다. 자동차산업을 지역산업으로 특화시켜 지역경제발전을 도모하기 위해서는 연관산업의 공간적 집적을 이루어 생산과정의 유연화를 창출해야 할 것이다. 최근 자동차산업은 적기조달방식과 모듈생산의 진전으로 완성차업체와 부품업체간의 지리적 근접성이 중요한 입지결정 요인으로 작용하고 있으며, 모듈생산방식은 기존의 공장에서 시도되기 보다는 새롭게 개발된 공장에서 주로 시도되고 있는 것으로 나타나고 있다. 따라서 지역단체는 우호적인 기업환경의 조성과 적극적인 기업유치전략을 통해 모듈화된 부품공급이 가능하도록 집적화된 산업단지의 육성을 도모해야 할 것이다.

본 연구에서는 총 유입 (1,100 mm)의 반 정도가 강우로부터 유입되었고, 나머지는 관개로부터 유입되었다. 유출은 총 유출량의 반 정도(47${\sim}$54%)가 배수에 의한 유출이였으며, 식물의 성장을 위한 증발산량이 40${\sim}$46%이었다. 지표배수의 경우 강우에 의한 유출과 중간낙수가대부분을 차지하였다. 인과 질소의 영양물질 수지는 유입수의 대부분은 시비로부터 공급되고(78${\sim}$96%),대부분의 유출은 식물체생산(86${\sim}$94%)으로 발생되었으나, 지표배수를 통한 영양물질의 손실량(6${\sim}$l2%)도 많은 부분을 차지하였다. 시비량의 차이는 지표배수를 통한 영양물질 손실과 수확량에 적은 영향를 미치는 것으로 보아 낮은 시비량적용만으로는 영양물질 유출을 감소시키기에는 큰 효과를 기대할 수 없다. 순배출부하량의 분석결과 논농사는 일반적인 강우량의 범위에서 오염물질배출원 보다는 수질 보호의 순기능이 있는 것으로 나타났다. 지표배수를 통한 영양물질 손실의 감소는 지표배수를 줄임으로서 효과를 기대할 수 있다. 담수심을 줄여 관개수를 절약하고, 논뚝에서 물꼬의 높이를 증가시키고, 강제배수를 최소화 하는 방법들은 지표배수를 저감하기위한 대안으로 제안된다. 이러한 영농방법은 물 절약과 수질 보호가 가능하지만, 영농방법의 변화는 수확량에 영향을 줄 것이라 생각되며 더 많은 연구를 필요로 할 것으로 판단된다.

This study is focused on forecasting the future of tole-democracy. Many Scholars expect that internet provides technological space needing realizing the tole-democracy or deliberate democracy. Especially in Korea, this expectation is higher than other nations because of political corruption and inefficiency. Therefore internet is intended to considering as new technologies reforming political process. In 16th the general election period, many candidates established home page and used as election campaign tool. And a little of home pages is payed attention to among voters. In spite of using internet as political medium, many political communication researchers have a doubt that internet will realize ideal direct democracy. It's reason is that internet is open and anonymous space. At anonymous space, communication participators is tended to be irresponsible and non-serious. Therefore it is hard that cyber-politics will be ideal type of democracy. In this context, this paper analyzed how pauicipators communicate with others at cyber bulletin board establishing candidate's home pages. Main research questions is how do discussions at cyberspace fulfill the conditions of deliberate democracy. Therefore, concrete questions include; who are participators at candidate's cyber bulletin board; which pattern do they communicate; what is the theme of communication; which effects do the anonymous character of cyberspace influence. To that purpose, this study conducted content analysis on 4,210 written matters at 82 cyber bulletin boards of candidate's home page establishing during 16th the general election period. It can be found that cyberspace in Korea still is not deliberate democracy space and not will be. Firstly, discussion patterns at cyber bulletin board is "candidate with supporters communication space. To be exact, it is said that candidate's home page is "the space of self-convincing among supporters." Secondly, the main themes of discussion are simple emotional expressions; "I support you!" "fighting" "Be vigor" etc. By contrast, real political contents'-central or local political matters - is relatively few. In the mode of expression, real political messages are more positive, logical than simple expressions, candidates private matters. Especially this characteristic will make cyberspace as "mutual slander space" consolidating anonymous characteristic of cyberspace. finally, Cyberspace in Korea still is not real "public sphere" realizing deliberate process. Therefore to be real public sphere, it is needed to participant's ethical maturity and political citizenship. In conclusion, it is difficult that cyberspace will reconstruct the Athene's Agora. On the contrary, Cyberagora will like to be irrespectable area fulfilling the sweeping. Making the deliberate space, technological possibility and ethical condition will have to be balanced together.

The persent study aims at finding out a means of prevention cool spell damages on the hilly areas. The irrigation plots of 24 hour stored water warm water way and warm water plots, cool water way are respectively established to find out water temperature and influnce on the growing rice plants. The results obtained are summed up as follows. 1. Warm water areas consisted of $5 m^2 Q=0.93 1{\ell}/sec$, V=31 cm/sec, S=1/1, 000, L=81.6m, B=5cm, h=6cm, t=4min 33sec, drops=9 areas, are constructed to help the water temperature of $14.5^{\circ}C$ rise to that of $21.6^{\circ}C$. This indicates lower temperature than $23^{\circ}C$ of critical water temperature in irrigation facilities by $1.45^{\circ}C$ and than $26.2^{\circ}C$ of balanced water temperature of Seoul arears by $4.6^{\circ}C$. But this does not give much influance on rice plant cultivation. 2. The rising of water temperature is influened according to the temperature, solar radiation but the water temperature changes according to the heat absorption of organized materials, weather and terraces. The difference of water temperature could be found in the first growing stage. 3. Through the warm water way of water rises to the temperature of $21.6^{\circ}C$ which also rises to the temperature of around $30^{\circ}C$ in the paddy field of submerged irrigation. The rice plants are comparatively free from prolonged cool damage, reproduction abstructive damage. 4. The water temperature in rice field in proportion to temperature influence of weather condition but the water temperature approaches to that of weather in the days of later growing stage and water temperature become lower than the air temperature in the fruit stage. 5. The water in the submreged field is $10^{\circ}C$ warmer than in the warm water way during the first growing stage period but the water temperature in the warm water way is warmer in the later growing stage period. The cool water of $14.5^{\circ}C$ is warmed to $30.1^{\circ}C$ and rice plants cultivation is free from other damages. 6. The 12% increased production or 570.98kg/10a is made cool water plot by rising the temperature of water from $14.5^{\circ}C$ to $21.6^{\circ}C$ making the water run through warm water way. 7. The damage inflicted by the cool water irrigation during the first growing stage period is the obstruction of peak tillering stage and the obstruction of heading the later growing stage period and the obstruction of fruiting and number of panides per fill.

This study was carried out to investigate the intake patterns of health food according to the kind of disease of the elderly aged over 60 years living in the Chuncheon area. This study was conducted by using a questionnaire from December 1999 to the March 2000. The data was analyzed using a SPSS program. The results were summarized as follows : The poorer the self- perceived health condition, the lower the level of activity of daily living(ADL) and instrumental activities of daily living(IADL) were the higher. the frequency score of health food intake. The incidence of disease, such as arthritis(44.7%), hypertension(18.8%), digestive diseases(17.1%), diabetes(10.5%) were found to be higher. than other chronic diseases among the elderly. The frequency score of health food intake was not significantly different according to self-perceived health status, disease status, or the level of ADL and IADl.. The must important source of information for health food intake was the recommendation of friends and relatives(68.7%). Twenty eight point two percent of the elderly considered health foods to be effective, however 8.3% of the elderly considered them to be ineffective. The elderly with chronic diseases had taken health floods in the descending order of neuralgia-arthritis, hypertension, digestive disease, diabetes. The elderly with digestive diseases, diabetes, renal disease, neuralgia- arthritis and respiratory disease were inclined to habitually take health floods once or twice per year. Intake of Korean traditional folk food was as high as intake of registered health food and Chinese tonic medicine. The most frequently taken health food was tonic medicine, which is fo11owed by pumpkin, ginseng products, herbal tea formula with black goat, deer antler and Kye-so-ju. Intakes of health food such as tonic medicine, blood of the deer, royal jelly, aloe were found to be higher among the elderly with chronic diseases such as diabetes, hypertension, and digestive disease. However, intakes of ginseng products, deer antler, pumpkin, herbal tea formula with black goat and Kye-so-ju were found to be higher among the healthy elderly. The elderly with neuralgia-arthritis had taken sixteen kinds of health foods. From these results, a wide consumer education program should be developed to convince people of the importance of well-balanced diet and to choose proper health foods according to the elderly's health conditions. Also, comprehensive and scientific research into Korean traditional folk foods are needed for the correct use.

Cooking practice is keenly related to not only the betterment of family health but to the improvement of dietary life. Cooking is a kind of practical skill and one is skill in it by repeated practice. The aim of cooking practice in school is to fix cooking method practically and scientifically, to acquire cooking skill. To achieve this aim there are many unrecognized or unsolved problems in the first-line schools. The problems and efficient ways of cooking practice in the middle and high school are as follows； 1. The aim of cooking practice： It should be first of all remembered that the practice is so practical that the knowledge and skill of cooking should be related to the future domestic life. Second, the practice should be able to serve the communal and national life by scientifying and improving life. 2. The content of the practice： First, it should be so arranged step by step that the content of each year should not be repeated. Second, the ratio of Korean cooking practice should be increased and the material of the practice should be chosen in consideration of the peculiarity of the community, seasons and economical problems so that it may be applied to the very day life. Third, to improve dietary life, the practice should be a way of the simplification of dietary life, of the nutritional efficiency. Forth, for the betterment of physical condition of the family the practice should involve balanced dietary plans and dietary therapy. 3. Teaching method： First, the practice should be scientific and comprehensive in consideration of not only cooking skills but also knowledge of nutrition. Second, micro-class system should be adopted, and practice labor should be allotted each student to develop cooperative attitude and the sense of responsibility. Third, in addition to the practice conducted in a body, comparative cooking, applicable cooking and experimental ability and the content of the text. Fourth, teachers should let the students examine and find problems by bringing them to a focus on the basis of theory. 4. Administration method： First, the practice schedule should be planned that a class has practices at least more than twice a semester. Second, two hours of class should be continued without cessation after beforehand survey and theory study. Third, facilities and utensils for practice should be enlarged. That is, cooking practice rooms, tools, utensils should be prepared. Fourth, enough cost of practice should be secured. The above mentioned points show the present situation and problems with which cooking practice teaching is confronted. In order to normalize cooking practice teaching, the first-line schools should give the above mentioned problems their careful consideration and improve the present situation so that efficient, creative, practical cooking practice will be possible.
