This study grasped problems and properties of rural tourism through Cooperative Tourism Development Model Project, so it provided to develop network program and to indicate long-term development direction. This study area was Gubyung-Areum village in Boeun-gun, Chungcheongbuk-do. This village has superior natural landscape and rich area theme. Also, this village was chosen in Areum Village Revitalization Project in 2002, infrastructure full equipment was achieved. Gubyung-Areum village is administering buckwheat flower festival and experience program by Bo-Eun County Office help to change the farm stay village to the rural experience village. But, there were some problems to operate in experience program. So that Chungcheongbuk-do Provincial Government Republic of Korea is propelling Cooperative Tourism Development Model Project for coping these problems from 2007.12.31 to 2008.9.30. This study is going to develop tourism network program that take advantage of enough area resources grasping problem of Gubyung-Areum village through propulsion of Cooperative Tourism Development Model Project. This study present Developing Strategies for Gubyung-Areum village through investigation, analysis and operation process.

This study examines the restoration project of Sokkuram, and introduces its preliminary plans by the architect Pai Ki Hyung. The restoration project started in 1958 with an inquiry committee of the restoration project, and was completed in 1964. Despite having undergone extensive repair work under Japanese supervision from 1913 and 1923, the repair work caused water leakages inside Sokkuram, and regular cleaning work that began in 1933 caused a lot of damage to the sculpture. In result of the surveys, the top priority of this project was to protect the sculptures inside Sokkuram by improving the environment of the cave. At that time, the architect Mr. Pai participated as a head of the fourth field surveyors to plan the restoration project and to design the preliminary plans. He proposed the installation of a double dome structure to prevent further water leakages on the concrete addition that was built up around the grotto by the Japanese. However, in 1961, the Cultural Heritage Committee of Korea examined the plans of Mr. Pai and immediately rejected them. The factors of the rejection were the omitting of entrance design, system of new double dome structure that presses the existing structure, and these changes that had to be made outside of the drainage plans. The repair work of Sokkuram began in 1961, and the main construction was building double dome structure and entrance installation. In this we realize that Mr. Pai's double dome structure plans were very important key concept of this project. This study attempts to demonstrate the double dome installations that Mr. Pai initially proposed, which ultimately remains as emblematic factors of Sokkuram's legacy.

The mentalis muscle is a paired muscle originating from the alveolar bone of the mandible. This muscle is the main target muscle for botulinum neurotoxin (BoNT) injection therapy, which aims to treat cobblestone chin caused by mentalis hyperactivity. However, a lack of knowledge on the anatomy of the mentalis muscle and the properties of BoNT can lead to side effects, such as mouth closure insufficiency and smile asymmetry due to ptosis of the lower lip after BoNT injection procedures. Therefore, we have reviewed the anatomical properties associated with BoNT injection into the mentalis muscle. An up-to-date understanding of the localization of the BoNT injection point according to mandibular anatomy leads to better injection localization into the mentalis muscle. Optimal injection sites have been provided for the mentalis muscle and a proper injection technique has been described. We have suggested optimal injection sites based on the external anatomical landmarks of the mandible. The aim of these guidelines is to maximize the effects of BoNT therapy by minimizing the deleterious effects, which can be very useful in clinical settings.

Galaxy clusters are known to be very bright in X-ray and contain a large number of X-ray point sources within the X-ray emission. However, due to the fluctuations of the X-ray emission, it is very difficult to detect faint X-ray sources and to extract accurately the photometric properties of the X-ray point sources in galaxy clusters. In addition, the most X-ray telescopes show spatially varying point spread function (PSF) and suffer from severe vignetting. The Chandra Archival Survey of Galaxy Clusters project is a wide-area ($\sim40deg^2$) survey of serendipitous Chandra X-ray sources in galaxy cluster fields, containing ~58,000 X-ray point sources in ~800 Chandra ACIS observations of ~600 galaxy clusters. This project aim to investigate the density environmental effects on the physical properties of the X-ray point sources, comparing physical properties of the X-ray point sources in galaxy clusters to those in typical fields. To utilize the sensitivity and detection probability of the X-ray point sources in galaxy clusters, we perform extensive Monte-Carlo simulations. In this poster, we compare the detection probability of the X-ray point sources in galaxy clusters to that of typical fields, and discuss quantitatively the difference between them.

This study examines the Gyeongju Seokguram Grotto restoration project (1961-1962) by architect Kim Chung Up (1922-1988) and introduces the documents he wrote at the time of planning. The study highlights Kim's Plan attempt to adopt Buckminster Fuller's idea of the Geodesic Dome, while inheriting the architect Pai Ki Hyung's previous design plan which was nullified. As Seokguram Grotto's water leak and deterioration issues have been brought up, the four-times survey was carried out by experts team between 1958 and 1960, under Ministry of Education's direction. Pai designed an initial restoration plan based on the survey's result, which was a double-dome structure with a concrete film on the outer periphery as a way to protect Seokguram Grotto in January 1961. However, as drawbacks, such as the heavy load of the concrete dome, and non-installation of entrance hall, have been indicated in the review process, the Cultural Properties Committee rejected the plan. Subsequently, Kim was appointed as the supervisor of the second restoration project. Kim drew up a process management schedule to be implemented from August 1961 to December 1963 and designed the conception plans for the second restoration design. This study analyzes Kim's Plan by examining sketches, site plans, floor plans, and sections. Kim planned to maintain the idea of the double-dome structure proposed by Pai while applying Buckminster Fuller's idea of the Geodesic Dome. Kim planned to lighten the dome structure by applying a steel-frame Geodesic Dome so that the dome structure could be supported by its own. The study is expected to reclaim the omitted parts from Seokguram Grotto's historical description and Kim's careers.

고체 추진기관이 노즐마개에 의해 외기와의 교환이 완벽히 차단된다면, 구조적 안정성은 제작초기 조건인 내부조성간의 잔류반응(Post Cure, Migration etc.), 그리고 자유공간 내의 산소(또는 산화방지제)와 습기(제습제)와의 반응에 종속된다. 이로부터 발생하는 혼합형 고체추진제의 기계적 특성은 매우 복잡하며, 추진기관은 발사직전까지 일교차/년교차의 끊임없는 열하중을 받게 된다. 본 연구에서는 고체 추진기관의 제조공정인 성형오븐에서 출고 후 저장안정화까지의 거동을 고체추진제의 열유변학적 단순특성을 적용하여 신속하게 산출할 수 있는 방법을 제시하였다. 이를 위해 온도제어 가능한 Endurance Test 장치를 고안 제작하였으며, 추가적으로 점진적 응력과 변형율 증가에 따른 비선형 특성도 검토한다.

본 연구에서는 다양한 산업에서 계면활성제로 적용되는 AOT를 HTPB/AP 고체추진제에 적용하였다. AOT는 음이온 계면활성제 중 하나로, 해외에서는 AOT가 추진제의 소화특성을 유도한다고 보고된 사례가 있다. 본 연구에서는 이러한 AOT를 적용한 고체추진제를 제조하였고, 물성과 연소특성을 고찰하였다. AOT를 적용한 추진제는 연소 시 일정 압력에 도달하게 되면 연소속도가 급격히 떨어지는 특성을 나타내며, 물성 특성에서도 밀도와 경도가 일반 HTPB/AP 추진제에 비하여 낮게 나타난다.

최근 건설 산업은 IT기술의 발전과 함께 새로운 기류를 맞고 있다. 컴퓨터를 이용한 다양하고 신속한 정보 및 지식관리가 이루어지고 있으며 사용자간 의사소통도 활발하게 이루어지고 있다. 이미 시공단계의 정보들을 처리해 주는 PMIS와 사용자들의 업무 노하우를 공유하는 수단인 KMS와 같은 시스템이 현장에 적용 되어 활용되고 있고, 최근에는 전자매뉴얼(IETM)로 대변되어지는 생애주기 전반의 법, 행정 절차제공자에 관한 연구로 범위가 확장되고 있다. 그러나 도시재생사업과 같은 대규모 건설사업의 경우 사용주체와 용도에 따라 주요 기능이 역동적으로 변화되는데 이 역동성은 전자매뉴얼 고유의 역할을 제한하기도 하고 기존의 시스템들과 경계를 모호하게 하기도 한다. 이에 본 연구에서는 경력 실무자들을 대상으로한 설문과 인터뷰, 건설프로젝트의 특성 분석을 통하여 건설분야 전자매뉴얼이 갖추어야 할 요소들과 설계 전략을 규정하고 이를 토대로 도시재생사업의 적용예를 통해 법과 행정절차 제공자라는 개발취지에 적합한 전자매뉴얼 개념 모델을 제시한다.
