The purposes of this study are to classify farm area and to develop farm system by region. The factor analysis was used as a main analysing tool to approach these purposes in this study. The farming of Kyung-Ju area in cropping sector is classified into 11 cropping systems. The distribution of specialized regions is very distinctive by the cropping systems. The specialized regions resulted from this analysis are different by factor. An efficient means to raise agricultural competitive power is to realize farm specialization by region according to productivity factor.

An improving example for traditional rapid mix system was studied in the base of mechanisms of alum coagulation. Local status of the major water treatment plants was also investigated and evaluated for upgrading these plants. A new design and operating criterium for rapid mix system was proposed to velocity gradient, G of $1,000-1,500sec^{-1}$ and detention time, t of 1 sec from the results of experiments and literature reviews. Comparing the present rapid mix system to this criterium, apparent difference existed between them. In this study, for improving Seongnam water treatment plant, a design criterium of velocity gradient, and detention time was set to $1,100sec^{-1}$, 1 sec, respectively. A new rapid mix system adopted the nozzle injection countcurrently cross the inlet pipe to the whole area. The injection velocity was 17m/s, nozzle diameter was 1.0mm, and number of nozzle was 70. The new modified system without running present four 75 HP agitators was able to improve water quality(based on sedimentation effluent) by 15-35% and to reduce electrical energy by 98%.

철근 콘크리트 구조물은 여러가지 복합적인 원인으로 균열이 발생한다. 이러한 균열은 내구성의 저하와 일체식 구조물의 외관을 손상시킬 뿐 아니라 철근이 공기중이나 해수에 노출되어 철근의 부식으로 콘크리트 구조물에 치명적인 구조적 문제를 야기시킨다. 본 연구에서는 서해안 A 항만 건설현장 케이슨 구조체의 일부 균열현상에 대하여, 유한요소법을 이용 Computer Modelling을 하고, 제작 및 진수, 예인, 가거치 등 시공단계별 구조해석을 통해, 균열발생원인을 규명하고, 올바른 시공법을 제안하였다.

국제합작투자는 선진국의 다국적기업들이 국제경영활동을 수행하는 대표적인 기업조직형태의 하나로 최근 학자들의 활발한 연구대상이 되고 있다. 특히 조직행동론적인 관점에서 합작투자의 합리적인 근거인 합작성(jointness)을 구성하고 있는 합작특질들과 합작기업의 성과간에 상관성 규명을 위해 이론적인 논의가 계속되고 있다. 本稿에서는 업종별 세가지 사례를 통해 한미합작선의 공통기여 특질이 한국측 합작선은 자본, 미국측 합작선은 지식을 통해 대미 합작투자가 이루어지고 있음을 밝혔다. 본 연구에서 살펴본 사례들은 縣案問題로 대두되고 있는 한미기업차원은 물론, 한국기업의 당면과제인 기술이전 문제와 미국 시장확보 및 급변하는 세계 기업환경에 대처 할 수 있는 효율적인 국제합작투자 전략의 대안마련에 一助가 될 수 있을 것이다.

This study has tried to illuminate a shocking phenomenon, the import liberalization of agricultural products in the aspect of Consumer consciousness. It has been applied that Table Analysis by using computer programming for instance-MINITAB, and Correlation Analysis and Multiple Regression Analysis, things like that. The results of this study are as follows; 1. Comparing domestic and imported stuffs, Comsumers came to awareness that domestic products superior to foreign's in the cases of the degree of freshness, taste and pollution damage, in the meanwhile, inferior to the cases of price and wrapping. Food self-supplyment is considered as one of the most important things of all, moreover, by most comsumers and health food and conventional food are favored by high class people. 2. Bying imported stuffs could clearly be fatal blow to our agriculture is fully recognized among consumers, what is more, there would only be doomed to our agriculture, too. 3. The most mass-purchasing imported stuffs by consumers illustrates in order; Beef, Banana, Coffee and Tabacco etc. The most significant elements why consumers buy foreign product is that the prices of them are relatively lower than those of ours. Besides, the next causes lies to non-producing stuffs and curiosity. 4. It must've been generally conceived by most consumers that Open-the-market-policy has been progressed for USA's repression and our monopolistic capital. Therefore, they demand that our market should be contained against unadviciable wave, moreover, keep paying attention to the policy how it will work to protect Korean agriculture. 5. Consumer attitude toward buying imported agricultural products is double-faced, Never-buy occupied only 24.4 % among respondents, but overwhelming respondents say non-producing stuffs can be obtained selectively. In this case, however, never-buy-movement would be backed by consumers in proportion to their educational background. 6. Various consumer minds surrounding Open-the-market-situation, in the end, has been analized econometrics through eleven variables to approach accurate fulfillments.

The main goal of this research was to develop a Golf course planning Methodology in terms of use and preservation of natural resources which consider balance of Ecosystem. This study suggested the necessity of analysis of natural resources in the development site prior to its planning. The analysis will give a benefits both the profits of private enterprise and national interests for reuse of natural resources. Study site was planned region of Kyungpook Country Club, which located near Weagwan. In connection with this study, natural resources which will reuse in the planning stage and soil status in the development site were analyzed.

The purpose of this study is to establish more rational and practical planning theory for amusementpark. It analyze and considerate the fluctuation of the people who come and use a Tong-Ch'on amusementpark. The results drawn from this research work are as follows ; There are considerable correlation between use fluctuation and some factors. The factors are season (spring, summer, autumn) as a time, temperature, cloud amount, duration of sunshine, weather (rainy day) as a climate and date (weekday, holiday) as a social system. The important variables are temperature, cloud amount, duration of sunshine and date (week day, holiday) to estimate the user of amusementpark. I can reduce the following two types of regression models. 1. () 2. () Y ; Number of User TEM ; Temperature CLO ; Amount of cloud SUN ; Duration of Sunshine WI ; Weekday W3 ; Holiday Those model is inorder to estimate the user for management of Tong-Ch'on amusementpark and use on the computation of facility size for reconstruction. Besides the amusementpark, city park and outdoor recreation area could estimate of user throuth this method. But, I am not sure about the regression models because I didn't apply the regression models to the other amusementpark, city park or outdoor recreation area. Therefore, I think that this problem needs to study in the future.

This study has been attempted to find out how the learning with the introduction of the physical environmental variant in earth science teaching-learning scene in high school can be approached to the goals of science education. And it also aims to seek for an effective teaching method of earth science education. The effectiveness of learning between two groups has been compared: the experimental group and the control group. According to the result of this research, the effectiveness of learning of the experimental group in the science branch of high school has been much higher than the control group while in the humanities branch, the effectiveness between the two groups is not conspicuous. In conclusion, the result of introducing suitable environmental variant into teaching-learning scene enhances the effectiveness of learning, and can be one of the desirable approaches to science education.
