Drosophila Sog and vertebrate Noggin play important roles during development. They function as antagonists against BMP4 signaling and induce neural ectoderm during embryogenesis. They are also engaged in appendage formation by inhibiting BMP4 signaling during late development. To understand further functions of Sog, Supersog, which is a more potent form of Sog, and Noggin BMP4 antagonists during development, I performed the molecular genetic analysis using Drosophila embryogenesis and wing formation as assay systems. In cellular blastoderm embryos, Sog inhibited Dpp signaling, Drosophila BMP4 signaling, whereas Supersog or Noggin did not block Dpp signaling. During wing formation, Sog inhibited Sax type I receptor of Dpp signaling whereas Noggin inhibited Tkv type I receptor of Dpp signaling. However, Supersog inhibited both Sax and Tkv type I receptors. These results suggest that functions of BMP4 antagonists are developmental stage dependent and indicate that each BMP4 antagonist inhibits BMP4 signaling by blocking different BMP4 receptors.

본 연구는 지속가능한 개발을 위한 컴팩트시티형 도시개발의 기본전략과 계획요소를 도출하여 개발제한구역내 도시들의 개발사업들을 분석하고자 하였다. 분석을 통해 얻은 결과는 다음과 같다. 첫째, 20세기 후반부터 선진국들은 컴팩트시티를 지속가능한 도시개발의 기준으로 삼고, 세부적인 도시개발계획을 추진하였다. 둘째, 이와 같은 지속가능한 컴팩트시티형 도시개발은 지속가능한 개발과 컴팩트시티 이론을 바탕으로 하며, 이 개발계획을 도시공간, 도시환경, 도시커뮤니티, 도시관리로 구분하여 계획요소를 도출하였다. 이를 바탕으로 개발제한구역 내 적용가능한 요소를 산정하고 컴팩트시티와의 관련 유형으로 분류하였다. 셋째, 과천, 의왕, 하남의 개발제한구역 내 다수의 개발계획들을 지속가능한 컴팩트시티형 도시개발과 비교해본 결과 유사점과 한계를 볼 수 있다. 이에 본 연구에서 분석한 바를 고려하여, 앞으로 개발제한구역 내 도시개발사업에 있어서 지속가능한 컴팩트시티형 도시개발의 정책적인 반영이 필요하다.

This study analyzed the attitude and effect of middle-age women on wearing girdles. Through this examination, we investigated types of girdles worn by middle-age women and compared and analyzed characteristics among types. By identifying middle-age women's need to wear girdles, this study enables effective development of girdles for middle-age women. Middle-age women's types of wearing girdles were analyzed according to three types of women wearing girdles: hate type, wearing preference type and inconvenience acceptance type. The hate type woman is frustrated with wearing a girdle because it impedes blood circulation, digestion, and causes fatigue. The wearing preference type woman wears a girdle to feel psychological satisfaction and self-confidence and thinks that wearing a girdle pushes the abdomen and supports the hip (hip-up effect). Women strongly agreed that body shape is made beautiful and the silhouette of the lower body is made beautiful by wearing a girdle. The inconvenience acceptance type of woman thinks it is inconvenient to wear a girdle, but nevertheless is satisfied with wearing a girdle. Based on findings of this study, development of girdles considering body shapes of middle-age women, development of soft materials and improvements facilitating dressing methods are needed.

With the development of digital technology and the advent of the concept of well-being, kitchen will be worked as the center of housing and turn into multi-functional space. So a research is requested to consider the users' needs for kitchen based on their life characteristics. The purpose of this study is to find out housing lifestyles, and to search and analyze users' needs for kitchen planning according to their lifestyles. And then plans for kitchen design are suggested. The findings are as follows. (1) Housing lifestyles of users living in apartment are categorized into the type of network and trial & development, pursing the new environment and technology, the type of high quality and convenience, seeking the way to make housework easy and comfortable, the type of housework oriented and the type of unspecification. (2) The type of network and trial & development requests home automation, confrontation layout of counter-top, the type of high quality and convenience requests enlargement of kitchen space, the newest appliance and kitchen island, the type of housework oriented requests the efficiency of space utilization with a counter-top style table, and the type of unspecification asks space for study and office work. All of the types have needs for water use space, larger storing space and a Kimchi refrigerator.

In machining with cutting tool inserts having complex chip groove shape, the flow, curl and breaking patterns of the chip are different than in flat-face type inserts. In the present work, an effort is made to understand the three basic phenomena occurring in a chip since its formation in machining with groove type and pattern type inserts. These are the initial chip flow, the subsequent development of up and side curl and the final chip breaking due to the development of torsional and banding stresses. In this paper, chip flow angle in a groove type and pattern type inserts. The expression for chip flow angle in groove type and pattern type insets is also verified experimentally using high speed filming techniques.

This study analyzed the perception types of women over the age of 60 in regards to attitude and the effect of wearing brassiere. In addition, it was also to provide the basic data demand for the development of a brassiere for elderly women. Q methodology was used for this study. Analyze the data using the QUANL pc program. Type 1 was the nipple cover non-preferred type. Type 1 thought brassiere has uplifting effect, but is uncomfortable and only worn when going out. Type 2 was a function-oriented preference type. They wore a brassiere for beauty and psychological satisfaction. The brassiere push-up the breast and enhanced volume. Type 3 was the pursuit of vibration reducing and beauty type. The brassiere reduced breast vibration and kept armpits comfortable. The brassiere was worn for beauty. In the future, the actual development of brassieres for elderly women should be investigated for wearing sensation and satisfaction.

The purpose of this study was to develop the strategy on activation of village by forest healing. Researcher conducted the questionnaire survey for forest healing village development to classify the mountain's characteristics by the three factors(linkage resource, program, facilities). In result, village characteristics were divided into two types: single element outstanding type(resource), complex element outstanding type(resource+program, resource+facilities). The development of forest healing village have to focused on the forest healing service recipient and mountain village characteristics. In conclusion, relationship between forest healing recipient and mountain characteristics was as follows: single type (resource) - public; complex type (resource+program) - chronic disease, social vulnerable people; complex type (resource+facilities) - severe disease. The detailed guideline for forest healing village needs to be established according to the mountain characteristics.
