Cleft lip, cleft palate, cleft lip and palate are the most common congenital anomalies in cranio-orofacial region. These anomalies lead to esthetic problem as well as to difficulties in feeding and speech and also to chronic infection of upper airway and to disturbance of jaw growth during growing up. Especially, some difficulties during feeding make parents to be confused and puts infants in dangerous position. But these difficulties can be controlled by proper feeding methods according to pattern of cleft lip and palate. Among these feeding methods, feeding appliance is the most safe and relatively easy to manufacture. Early wearing of this appliance makes cleft lip and palate infants to a normal feeding and weight gain. As a member of team approach for the treatment of cleft lip and palate, a pediatric dentist should solve the feeding problems which cleft lip and palate infants and its parents are confronted and help in receiving further treatment.

In order to understand the influence of colours on the urban design of a city, a portion of the central Chung-Ju was chosen as the study area, and three cases were researched as colours. These surveyed colours are analysed in their hue, value and chroma. It was necessary to determine the colours of 272 buildings exterior in all in order formulate the findings presented in this study. The result of this study can be briefly summerised as the following ; 1) The trends in the use of colour turn out like this ; 55.3% of the building were Y(yellow), YR(yellow-green), R(red) Family in Hue, abour 33.9% of them were within 8.0-8.9 and 26.6% were within 7.0-7.9 on the value scale, and about 48.5% of them were within 1.0-1.9, 2.0-2.9 and 3.0-3.9 on the chroma scale. 1) For case 1 on the exterior colours of buildings, about 57.8% were Y and YR family in Hue, about 53.7% were 8.0-8.9 and 7.0-7.9 in Value, and about 49.6% of them were within 1.0-3.9 in chroma. 2) For case 2 on the exterior colours of buildings, about 52.4% were Y and R family in Hue, about 65.1% were 7.0-8.9 in Value, and about 46% were 1.0-2.9 in Chroma. 3) For case 3 on the exterior colours of buildings, about 55.7% were Y and YR Family in Hue, about 72.1% were 7.0-8.9 in Value, and about 31.1% were 2.0-2.9 in Chroma. In summary, the colours of the building surveyed in central Chung-Ju can be characerized as Y, YR, R, N family in Hue, 7.0-7.9, 8.0-8.9 in Value registered in 1.0-1.9, 2.0-2.9, 3.0-3.9 in Chroma. The observed exterior colours show a tendency toward Yellow in Hue, High in Value and low in Chroma. Generally, the majority of the colours is light rather than strong in tone.

To obtain a large amount of VU-4 calmodulin (115, Lys to Ile). VU-4 calmodulin gene with Ptac promoter (680 bp) was cloned into a plasmid, pUC18. Newly cloned pUC18/VU-4 was transferred into E. coli UT481. The plasmid isolated from cell extracts of the transformed E. coli was analyzed by restriction mapping and yielded the expected restriction endonuclease map with BamHI and EcoRI. Calmodulin was detected by Western blot analysis using chemiluminescence protocol and the estimated expression level was 60 pmole calmodulin/mg protein. Calmodulin was purified from the E. coli cell extracts by Ca^(2+)-dependent chromatography on a phenyl-Sepharose column. The purified calmodulin was identified as a mutant VU-4 calmodulin by SDS-PAGE and methyltransferase substrate test.

정책변동의 지연과 한계에 관한 연구 : 농어촌구조개선사업을 중심으로 The Case of the Farming and Fishing Restructuring Program in Korea

이준수,최흥석 한국정책학회 2003 韓國政策學會報 Vol.12 No.4

본 논문은 개방 농업 시대를 맞아 우리 나라 농촌부문의 경쟁력 저위 문제의 해결을 위해 총 67조원 규모로 1992년부터 시작된 농어촌구조개선사업의 정책 변동 양태와 정책 변동 지연 및 한계 현상의 원인에 대한 고찰이다. 본 논문은 분석의 도구로 시스템 다이내믹스 이론을 활용하였다. 우선 농어촌구조개선사업은, 전략적 측면의 경우, 양적인 인력관리 면에서는 인력의 진입단계관리 위주의 정책에서 퇴출장벽관리 강화의 방향으로, 질적인 인력관리 면에서는 개별 영농 기술 교육위주 정책에서 종합경영능력 교육 강화의 방향으로 정책이 변동되어왔다. 그리고 운영적 측면의 경우, 집권적 운영 통제 방식으로부터 개별 농경 주체를 통한 분권적 정보·환경 대응력 강화를 지원하는 방식으로 정책이 변동되어왔다. 그런데, 이 사업은 초기부터 대규모성, 구조조정성격, 자금지원위주, 정치성, 시기적 급박성 등의 독특한 성격을 가지고 출발했기에, 이로 인해 기존 정책의 경로의존성과 관성을 강화시켜 정책의 올바른 변동을 지연시키는 결과를 낳았다. 더욱이, 인력정책 주체 입장에서는 통제가 어려운 관련 변수들 - 국제 농산물 협정, 토지 정책 등 - 의 영향을 받아, 전략적 측면에서는 농업인력 퇴출장벽 제거의 한계상황에, 운영적 측면에서는 직접적·집권적 정책 개입 수단으로의 회귀가 촉진되는 한계상황에 직면하게 되었다. This study investigates the reason for ineffectiveness and delay in the implementation of the farming restructuring program in Korea. It uses system dynamics as the main analytical tool. Policy learning occurred so as to change the focus of the program at the strategic, as well as operational, level as it became evident that the program did not work as intended. As to the strategic level, the program initially focused on improving the quality of human resource entering into farming, but later on changed its emphasis to encourage farmers to exit the farming industry while trying to enhance managerial capacity of remaining farmers. At the operational level, the program sought decentralization in an effort to utilize local information and to strengthen adaptability to environmental changes. However, the policy learning was bounded to be slow and quite limited. The change of the program focus was slow because of the inertia and path-dependence, which in turn results from certain characteristics of the program such as massiveness, politicization, urgency, and so on. The extent of program change was quite limited because of some uncontrollable variables such as regulatory provisions of international agricultural agreements, the structure of land use, and traditional values concerning farming.

프레임분석을 통한 수자원 갈등 각 이해집단의 의미구성 이해 : 한탄강댐 건설 사례를 중심으로 the focus on the case of the river Hantan Dam construction

주경일,최흥석,주재복 서울대학교 행정대학원 2003 行政論叢 Vol.41 No.4

본 연구는 최근 부각된 사회갈등 중에서 정부에 의해 국가적 수준에서의 해결 과제로 지정되어 그 심각성 정도가 공인된 바 있는 한탄강댐 건설을 둘러싼 사회갈등문제를 인지 프레임의 시각에서 접근하였다. 사회갈등문제에 접근할 때 문제해결의 객관적 해답과 조건의 존재를 가정하고 이의 발견에만 초점을 두어 온 기존의 접근방식과는 차별화된 시각이 보완적으로 공유되어야 한다고 생각했기 때문이다. 또한, 사회갈등문제를 해결하기 위한 시발점이 갈등 현안을 둘러싼 각 이해집단들의 인식 속에 자리한 집단 해석적 정향의 체계적 이해에서부터 발원되어야 한다는 믿음 때문이기도 하다. 분석 결과, 한탄강댐 건설 갈등의 각 이해집단들은 댐 갈등의 의미를 이해하고 이에 대응하기 위해 서로 상이한 4가지 차원의 상위 갈등 프레임을 형성하고 있었으며, 각 차원 내에서도 각자의 입자에 따라 역시 상이한 프레임 내용들을 구축하고 있음을 알 수 있었다. 결국, 이러한 분석 작업들은 각 이해집단들의 현안 이슈에 대한 근본적 해석정향과 바람직한 갈등관리방식에 대한 태도 및 상대방에 대한 인식, 평가 등을 알 수 있게 함으로써 갈등 당사자간 상호 이해 합의형성 구축의 기초 자료로서, 또 3자에 의한 효과적인 중재절차의 개발에 있어서 그 유용성이 크다고 생각한다. This study approached social conflict around the river Hantan Dam construction as problems of state level in recent social conflicts in terms of cognitive frame. When we approach social conflicts, we usually try for the objective resolution and condition of the problem. But we need to share the different approach from this try now. Namely we need to understand systemically collective interpretive orientations which embedded in stakeholder groups' cognitions on the social conflict problems. According to this study and analysis, each stakeholder group around the river Hantan Dam construction constructed the different four dimension meta-frame to make sense the meaning of Dam conflicts, and also constructed the different frame contents in the each side of dimensions according to stakeholder group's position. Finally, this results imply as fundamental date for consensus-building among stakeholder groups and the organizing effective mediation-procedure because we understand the stakeholder groups' basic interpretive orientations about the present issues and the way of thinking of desirable conflict management systems, the characterizations of the other side by this results.

We evaluated CT findings of the small cell carninoma, which presented as a solitary pulmonary nodule at the periphery of the lung parenchyma. Of pathologically-proven 45 patients with small cell carcinoma, 10 patients was included in this study, who had a solitary, peripheral lung nodule at distal portion of the subsegmental bronchus. We retrospectively reviewed clinical data and CT findings including size, location, margin, enhancement pattern, lymph node enlargement, metastasis. Peripheral small cell carcinomas were 22.2%(10/45). All masses had well-defined margin and lobulated margin was seen in 7 patients. Mean diameter was 3.8cm (2.5-7.0cm). Enhancement pattern were homogeneous in 3 cases and inhomogeneous in seven. Calcification or air-bronchogram was not present, and focal cavitation was seen in one case. In five, only lung mass was present, and lung mass with lymph node enlargement was seen in one. distant metastasis without lymph node enlargement was noted on two patients and another two patients showed lymph node enlargement and distant metastasis. Peripheral small cell carcinoma is not rare(22.2%). Most frequent CT finding is a well-defined, lobulated mass with inhomogeneous enhancement, these findings would be helpful in differentiating small cell carcinoma from other neuroendocrine tumors when differentiataion is difficult cytologically.

The aim of this study is to identify the data traffic capacity of 3G mobile communication networks, especially of cdma2000-1X networks. Three-layered ON/OFF traffic model is used to describe the dynamics of data traffics and the process of data transmission such as packet scheduling. We construct a simulator fully incorporating packet handling process of cdma2000-1X data network as well as three-layered ON/OFF traffic model describing the behavior of source data traffics. To get influence of traffic parameters on performance measures, the extensive simulations were performed for several data sets which are obtained from real trace data or previous studies. The experimental results show that the engineered throughput satisfying QoS criteria is approximately 20% of total capacity. Finally, some proposals to improve the system capacity are followed.
