The purpose of this study was to compare the effect of tetracycline HCL, Citric acid and PrefGel applied on the root surfaces that planed with periodontal curret with Roto bur. In this study, 20 extracted teeth with advanced periodontal disease were used. The teeth were root planing with periodontal curette and Roto bur. Following root planing, each agents was burnished on the prepared root surface for 3 minutes to find opened dentinal tubules. And then, each specimens were investigated using scanning electron microscope. Amount of remained cementum by loss of tooth substance index and the number of opened dentinal tubules were evaluated to each specimens The results were as follows. 1. Groups treated with periodontal curette were almost seemed no removed. Other groups treated with Roto bur showed partially opened dentinal tubule orifices. 2. Loss of tooth substance index were compared between groups. There was no statistically difference between periodontal curette groups. Between Roto bur groups was alike. But there were statistically differences between periodontal curette and Roto bur groups. 3. At comparing with various root conditioning agents, Tetracycline HCL group took statistically higher than Citric acid and PrefGel in opened dentinal tubules. On the other hand, there was no statistically difference between Citric acid group and PrefGel group. As a result of this study, groups treated with Roto bur showed more cementum removed than groups treated with periodontal curette. In a treatment for regeneration of periodontal tissue, it was regarded that Roto bur should be used and that Tetracycline HCL would be more effective as chemical root conditioning agent.

Duodenal diverticulitis is a rare complication of the duodenal diverticulum. Its rarity is due to the relatively large diameter of the duodenum, which makes the intraluminal flow of sterile liquid duodenal contents fluent. Additionally, nonspecific signs and symptoms of duodenal diverticulitis make it very difficult to diagnose properly. We describe a patient presenting with abdominal pain, nausea, and leukocytosis, with diverticulitis of the third portion of the duodenum caused by the impaction of a foreign body, who was diagnosed and treated with enteroscopy.

Underground facilities are closely related to city safety, and since 1996, South Korea has been carrying out a computerization project for underground facilities under the supervision of the Ministry of Land, Infrastructure and Transport. Although the underground facility DB built through the underground facility computerization project is being built and managed by 161 local governments across the country, there is a need for a reliability evaluation plan for the already built DB. Therefore, in this study, the definition of the DB layer of the underground facility information integration and utilization system was investigated to derive the criteria for determining the reliability of the underground facility DB. 9 properties commonly included in the 7 underground facility layers were identified, and reliability was evaluated for exploration classification, installation date, and pipe quality. It was derived as a property. Considering the influence of the derived attributes on the quality of underground facilities and the development of surveying technology, the indicators were quantified and problems were analyzed through application. Evaluation criteria was adjusted through problem analysis, and the adjusted evaluation criteria was applied to the previously established underground facility DB of local governments. The result of the study is to prepare a quantitative evaluation plan by reviewing various attribute information included in the computerization performance of underground facilities. It will be possible to improve the efficiency of DB management work. In order to use it as an index for managing underground facilities in the future, it is judged that institutional analysis for the introduction of the quality rating system for underground facilities along with additional application is necessary.

선적용 컨테이너를 활용한 해외 건축물의 환경,친화적 특성에 관한 연구 -자원절약 영역을 중심으로-

본 연구는 국내에서 선적용 컨테이너를 활용한 건축 시 올바른 친환경적 건축 자원절약을 위한 기초적 인식 자료로 제공되는 것이 목적이다. 이 연구에서는 해외의 컨테이너 건축물들의 친환경과 관련된 형태, 구조, 기능, 재료 등의 특성을 파악하고, 선적용 컨테이너가 자재로써 건축물에 사용됨에 있어, 특히 형태, 구조, 기능, 재료 등의 특성들의 연관관계 속에서 자원절약, 환경오염 및 훼손의 문제 등을 함의한 친환경성의 요인들을 파악하려했다. 국내에서 발표된 선행연구들에서 나타난 중복된 다수의 컨테이너 건축물의 특성들을 3R 개념(재활용, 재사용, 절감)과 연관해 9개의 주요특성(가변성, 모듈성, 견고성, 신속성, 경제성, 친환경성, 이동성, 집단성, 구조·조합성)으로 함축하여 분류했고, 이를중심으로 컨테이너건축 사례로 선정한 해외 건축물 9개를 3종의 건축 유형으로 구분하여 각 사례의 주요 특성들과3R 개념의 친환경성과의 상관관계를 분석하였다. 분석결과 건축물에 컨테이너를 활용하는 것은 3R 개념 중 ‘reuse’의 영역에서 가장 높은 지속가능한 친환경적 순환 가치를 나타내고 있었고, 컨테이너 특성 중 직접적인 ‘친환경성’을제외한 나머지 8개의 영역에서도 모두 친환경적 순환가치에 비중 높은 영향 관계에 있음을 나타냈다. 결론으로 선적용 컨테이너의 건축 활용 시 지속가능한 자재활용 순환주기의 실현을 위해 중고 해운컨테이너 사용, 조립·해체를 고려한 비변형 설계원칙 마련, 시공 시 모듈을 해치거나 ISO 규격을 변경하는 행위의 자제, 과도한 이질 재료와의 혼용사용 자제 등을 통해 가능한 것으로 나타났다. 해외에 비해 국내 컨테이너건축을 위한 친환경적 인식이 아직 부족하다. 국내에서도 컨테이너의 친환경적 활용을 위한 기술적 여건이 시급히 마련되어야 할 것이다. This study aims to provide a basic data for utilizing architecture containers in Korea in order to use and save environmental resources. It explores not only to examine the morphological, structural, functional, and material properties associated with eco-friendly containers in the foreign countries but also to focus mainly on the eco-friendly utilization and interrelation among several architectural ones(including the degradation of landscape). The characteristics of architecture shown in the precedent studies are classified into the nine types(Flexibility, Speed, Transportation, Modularity, Economic, Efficiency, Associativeness, Sturdiness, Environment-Friendly, Mixed Structures) related to 3R concepts(recycle, reuse, reduce), and then analyzed the nine overseas architectures by categorizing them into the three types of container. The analysis shows that the reuse takes the more advantage among the 3R concepts. Furthermore, this makes it clear what there is an direct or indirect relation with the eco-friendly container. Additionally, the other eight types except the Environmental Friendliness are identified as the important factors for the cycle of resources in terms of sustainable use in the construction plans, architectural design, assembling and dismantling. In Korea, the knowledge of container construction is still incomplete compared to that of foreign countries. Therefore, it’s environmental use should be settled properly in the nearest future.

강승모(Seung Mo Kang),Hamada Abdelmotalib,고동국(Dong Guk Ko),박외철(Woe-Chul Park),임익태(Ik-Tae Im) 대한기계학회 2015 大韓機械學會論文集B Vol.39 No.11

본 연구에서는 서로 다른 항력 모델이 원추형 유동층 연소기 내의 수력학적 특성과 열전달 현상에 미치는 영향에 대해, 입자상 유동에 대한 분자운동론을 적용한 오일러-오일러 모델을 사용하여 수치해석적으로 연구하였다. Gidaspow 항력 모델과 Syamlal-O’Brien 항력 모델에 대해 유입 공기의 속도와 입자의 크기를 변화시키면서 연소기 내의 압력강하나 베드 팽창률 및 벽과 베드 사이의 열전달 계수의 변화를 조사하였다. 그 결과 베드의 팽창률은 속도가 증가함에 따라 커졌으며 압력강하는 속도의 증가에 따라 감소하였다. 벽과 베드 사이의 열전달 계수는 유입 속도가 증가하면 증가하고 입자의 크기가 증가하면 감소하는 것으로 나타났다. 베드의 팽창률이나 압력 강하와 같은 수력학적 특성은 항력 모델에 큰 영향을 받지 않았으나 열전달 계수는 항력 모델에 따라 차이가 나타났다. In this study, wall to bed heat transfer and hydrodynamic characteristics in a conical fluidized bed combustor was investigated using computational fluid dynamics method. A two-fluid Eulerian-Eulerian model was used with applying the kinetic theory for granular flow(KTGF). The effects of the two drag models, Gidaspow and the Syamlal-O"Brien model, different inlet velocities(1.4Umf~4Umf) and different particle sizes on the hydrodynamics and heat transfer were studied. The results showed that the hydrodynamic characteristics such as bed expansion ratio and pressure drop were not affected significantly by the drag models. But the heat transfer coefficient was different for the two drag models, especially at lower gas inlet velocities and small particle sizes.
