This experiment was carried out to analyze, compare, and examine the effect which pasteurizing temperature (LTLT: 65℃/30minutes, HTST: 72-75℃/15seconds, 82℃/25seconds and UHT: 135℃/2seconds) in industrial pasteurizing method of milk affected to form volatile carbonyl compounds, flavor components of market milk, by TLC and GLC, and to search fundamental data for the flavor of market milk. The results obtained were summarized as follows: 1. The volatile carbonyl compounds identified by TLC, only 3 components of formaldehyde, acetaldehyde and acetone were detected in raw milk. But formaldehyde, acetaldehyde, acetone, and propionaldehyde were identified in pasteurized market milk, besides unidentified components were present. 2. The analytical results by GLC, no heated raw milk was the most abundant in 70.26% of acetaldehyde, and was consisted of 27.28% of formaldehyde, 2.46% of acetone. 3. In the market milk pasteurized by low temperature long time at 63℃ for 30minutes, the volatile carbonyl compounds was consisted of 69.97% of acetone, 14.92% of acetaldehyde and 3.23% of formaldehyde, and 8.01% of 2-heptanone and 3.87% of propionaldehyde, not present in raw milk, were produced. 4. The market milk pasteuized by high temperature short time at 72-75℃ for 15seconds was consisted of 51.18% of actaldehyde 17.19% of acetone, 14.57% of propionaldehyde, 8.37% of formaldehyde and 3.98% of 2-heptanone, and 2.62% of diacetyl, 1.19% of n-pentaldehyde and 0.90% of n-butryraldehyde were produced unlike the market milk heated at 63℃. 2-heptanone (19.99%) in market milk pasteurized at 82℃ for 25seconds was suddenly increased in comparision with the market milk pasteurized at 72-75℃ for 25seconds. Acetaldehyde (54.64%), n-butyraldehyde (1.73%), n-pentaldehyde (2.06%) and diacetyl (2.78%) also were slightly increased. However, formaldehyde (1.99%), acetone (8.87%) and propionaldehyde (7.92%) were shown the decreased tendency. 5. The market milk pasteurized by ultra high temperature at 135℃ for 2seconds was contained of 57.69% of acetone, 27.47% of acetaldehyde, 11.17% of 2-heptaneone, 2.08% of formaldehyde and 1.59% of propionaldehyde, and a trace amount of n-butyraldehyde, diacetyl and n-pentaldehyde were generally similar to those of market milk heated at 63℃ in component pattern.

Socio-cultural transition and the change of life styles in the early stages of 20C had been affect the styles of contemporary architecture. The development of house form in recent times is based on the formative period of contemporary architecture. This paper intends to comprehend the compositional principles of contemporary dwelling house, based on historical and contemporary conception of style. When we consider a style as the ontological reality, it can be possible to describe the style in formal and spatial aspects. In this paper, a style is interpreted in the view point of typological approach and the frame of interpretation is organized into three categories, mass, facade and element.

문화도시의 조성은 새로운 것을 만드는 것이 아니라, 지역주민의 삶 속에 있는 문화적 맥락을 찾아 활성화시 키고 가치를 부여하는 것에서 출발되어야 한다. 문화의 내용은 예술ㆍ종교ㆍ전통ㆍ사회처럼 고도로 형식화 되고 제도화된 형태로부터 자유분방하기 이를데 없는 일상적인 삶의 형태에 이르기까지 다양하게 펼쳐져 있 다. 문화의 다양하고 복잡한 내용을 삶의 장소에 반영하기 위해 영역간 소통을 위한 상보적 개념과 사람들의 장 소에서의 움직임과 공간의 인식성을 높여주기 위한 연속성 개념을 도입하였다. 대상지역의 도시문화는 가로공간 중심으로 형성되어져 왔다. 이를 통합한 문화단지로 발전시키기 위해 기존 종교시설의 오픈스페이스 활용, 기존 건물의 리노베이션 그리고 상징적 문화복합센터의 건립을 통한 단지재 생이 필요하다. 본 연구에서는 시설 전환을 위한 기획의 과정과 방법, 이이디어를 발전시키는 단계 그리고 전환설계의 방법을 제시하였다. Urban culture and religion do not have separate societal roles ; rather, they are complex elements and combine with the existing organization of modern paradigm. By doing so, they are able to maintain the identity and context of the city and conversion as the continued space of the new urban culture. This study is carried out by the next three staged. ㆍContemplation on the relationship and social roles between urban culture and religion. ㆍConsideration on continuity, conversion concept, characteristic deduction and architectural application. ㆍFinding new possibilities through culture complex center with the features applied.
