논에 설치한 유아등에 채집되는 멸구류를 비전문가들도 쉽게 동정할 수 있도록 인터넷에서 운영할 수 있는 하이퍼텍스트 기반의 검색표를 개발하였다. 그리고 정확성 검정을 위해 곤충 동정 경험이 없는 12명의 대학생을 대상으로 그 효용성을 평가하였다. 그 결과, 흰등멸구의 동정 정확성은 56%에서 83%로 증가하였고, 애멸구의 동정 정확성은 47%에서 80%로 증가하였다. 그러나 벼 멸구의 동정 효율을 높이는데는 충분하지 못한 것으로 나타났다.

A field case study was performed to investigate the effect of shallow ponding in paddy field on irrigation water requirement of direct seeded rice. In addition, an economic analysis was made to see the effect of no-till direct seeded rice on cost reduction. A field study was performed at a 2.1ha paddy field in Kimjae city, Chonbuk province from 1991 to 1999. Various direct seeding methods such as dryland seeding, wetland seeding, and no-till wetland seeding were introduced. Then, cost reductions due to the direct seeding and no-till were calculated. In addition, to investigate the effect of shallow ponding on irrigation water requirement, field measurements such as irrigation water volume, drainage water volume, rainfall depth, and ponding depth, were made at a 40a plot within the same area in 1988 and 1990. The results of the shallow ponding study showed that the irrigation water depth, rainfall, and the drainage depth were 379mm, 458mm, and 448mm in 1988 growing season, and 274mm, 819mm, and 736mm in 1990, respectively. The shallow ponding irrigation method saved irrigation water by about 20% with higher yield compared with the traditional method. The economic analysis showed that won \640,000 per ha can be saved by direct seeding due to no nursery cost, and \1,220,000 per ha due to no-till and no nursery cost. The yields ranged 540 to 640 kg per 10a during the study period with an average of 590kg per 10a. If these cropping techniques with no-till direct seeding and shallow ponding depth for rice cropping prove to be advantageous with further study, they can be adopted for the most of the paddy fields in Korea.

유휴논토양에서 reed canary grass를 재배하였을 때 액상구비의 단기간(3년간) 시용효과를 조사하였으 며, 그 결과를 요약하면 다음과 같다. 1. 모든 예취빈도에서 1993년의 건물수량이 다른 재배년도보다 많았다. 2. 액상구비의 시용수준별 평균 건물수량은 3회 예취구의 360 kg 수준에서 13.10 ton , 4회 예취구의 360~480 kg 수준에서 12.50~12.83 ton 5회 예취구의 450~600 kg 수준에서 12.52~

유휴 논 토양을 이용하여 reed canarygrass를 재배하였을 때, 건물 수량에 미치는 무기태 질소의 단기 시용효과를 조사하여 건물 생산효융이 높은 경제적 시비수준파 척정 예취빈도를 추정하려고 하였다. 1. 모든 예취빈도에서 1993년의 건물 수량이 다른 재배년도보다 유의하게 많았다. 즉, 3회 예취구에서 는 시비수준 평균 14.40 ton , 4회 예취구에서는 13.88 ton , 5회 예취구에서는 15.98 ton 을 나타내었다. 2. 시비수준

학제간 연구의 방법과 필요성이 절실한 가운데 감성과학에 대한 철학적 배경을 논의하고 탐구하는 일은 매우 의의있는 일이라 생각된다. 전통적으로 서구사상에서 인간의 인식능력은 감성과 이성이라는 이분법으로 나뉘어 온 터에 그것에 관한 전체적인 모습은 그 상호관계를 모색하는 일에서 찾아져야 할 것이다. 특히 이성의 감성화나 감성의 이성화를 통한 접근이 가능한 데, 이는 ‘감성적 인식의 학’이 어떻게 이루어지는가의 문제이다. 가성적 인식은 논리적 인식에 비해 저금한 것으로 여겨져 왔으나 여태가지 논리적 인식이 수행하지 못했던 세계인식의 폭을 유비적 관계에서 확장하고 보완하는 역할을 한다. 칸트적인 맥락에서 미적 판단 혹은 감성적 판단은 논리적·개념적 판단을 보충한다. 공통감에 근거를 둔 인문학의 지평에서 감성의 문제를 자연현상의 관찰에 토대를 둔 과학적 객관성에까지 높이되, 아울러 그 한계를 지적하는 일이 중요하다고 하겠다.

Soengyo-jang has some characteristics as the most great house, the special functions, and the non-regional type of house form. And it has constructed continuously for two centuries by many owners in the different generations, It needs a special research method ; which are consist of a) comprehension of background information from documents and oral instructed materials, b) pursuit of design process through the building survey, and c) theoretical interpretation about 'collectivism'. From the results of this research, it is revealed that the architectural purpose of this house was constructing 'a great manor'. At first phase, it had been a single ordinary house, at second, it had expanded to a complex including many housing clusters, and finally became to expand its dwelling territory into whole village. Its expansion was progressed by the four collecting phases of which were building, building cluster, group of clusters, and topological setting. Main design elements operated in each of collecting phases ; they were partial element of <Ondol+Floor>, exterior spaces of <Madang>, a linear building of <Haenglang>, and a pavilion of (Hwalleajeong>. The last two elements were also powerful datum.

One of the main purposes of architectural history is the analysis of existing designs in order to find laws and orders of certain types, while space planning emphasizes the generation of design. In this study, relational space planning methodology is used to generate Chosun upper-class housing prototypes based on 'Yaejae' logic model. During the Chosun Dynasty era in Korea, Confucianism was the ruling ideology for its society. The patio type house was the main upper-class housing type during the Chosun Dynasty, and it can be viewed that space planning was heavily influenced by the law of 'Yaejae' in Confucianism. The logic of 'Yaejae' can be interpreted as relationships between spaces. Relational space planning methodology that reasons through constraint propagation is used to generate prototypes. Prototypes are compared in order to verify actual applications of the logic into space planning.
