본 연구는 도시공원의 식생경관을 보전하여 도시의 개성과 아름다움을 창조, 유지, 관리할 수 있도록 하기 위한 기초적인 연구로써, 도시공원의 식생경관이 주변의 건축물 등과 조화를 이룰 수 있도록 개발을 유도할 수 있는 방안을 모색하고자 하였다. 광주공원의 식생경관을 대상으로 CAD에 의한 시각 시뮬레이션 응용방법에 의한 분석은 앞으로 시각 시뮬레이션 방법이 식생경관을 보전 할 수 있는 객관적인 판단 근거를 제시할 수 있는 가능성을 보여주었다. 그러나, 본 연구와 같이 근거리의 식생경관을 분석할 경우는 수목의 위치, 수목의 성상, 식생구조 등이 매우 중요한 요소로써 인식되고 있다. 따라서 분석작업의 효육을 높이고 컴퓨터의 활용효과를 높이기 위해서는 대상지에 대한 면밀한 조사방법과 수목의 표현방법, 그리고 상세한 자료입력방법에 대한 지속적인 연구가 필요한 것으로 사료된다.

This study presents a sociocultural study of 'traditional' as well as contemporary dietary construtions among Seoulites. It also represents the first interdisciplinary study of food between nutritional science and anthropology in Korea. This study was performed a case study based on in- depth interviews with those who were born around the Japanese occupation period and raised in Seoul experiencing radical social changes modern Korean history. The participants were mostly in their late sixties and very knowledgeable of 'traditional' foods of Seoul and the ways they were made and consumed. This interview data show the historicity of foods were used and understood differently in past and represented different understandings of, for instances, 'nature' and 'culture' of Seoulites. This study not only provides new approaches to food study but also identifies the common ground on which an interdisciplinary study of food between nutritionists and anthropologists can develop.

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.
