한국 고유의 전통적 목조 건축양식에 의해 지어진 한옥은 가옥형태의 다양화 및 친환경 주택에 대한 선호도 증가에 따라 관심이 증가하고 있다. 이에 맞추어 한옥 대중화의 일환으로 다양한 연구가 진행 중에 있다. 이러한 연구들 중 하나의 성과로 한옥의 3차원 정보교환을 위한 개방형 BIM연구에서 IFC-XML을 이용한 한옥부재 라이브러리와 개방형 BIM 기반 브라우징 모듈이 개발되었다. 중립 포맷인 IFC에는 형상정보와 XML링크정보를 담고, XML에는 파라메트릭 정보를 담아 이종 BIM 도구들간의 정보교환이 가능하게 되어 한옥설계를 지원할 수 있는 환경을 제공하였다. 하지만 XML을 통해 한옥부재를 제작하려면 이에 관한 전문 지식을 가진 전문가가 코딩을 해야 하며, 하드 코딩방식으로 코딩되기 때문에 한옥 개별부재 하나를 코딩하는데도 수많은 시간이 소요된다. 이를 개선하기 위해 본 연구는 코딩에 대해 지식이 없는 비전문가를 대상으로 하는 IFC-XML 자동구축시스템 개발을 목적으로 한다. 본 연구를 통해 비전문가도 자동구축시스템을 이용하여 각종 한옥 부재를 XML로 구축할 수 있다. 따라서 전문가의 도움 없이 개방형 BIM기반 3차원 한옥 부재 라이브러리의 지속적인 구축을 기대할 수 있을 것이다. Han-ok, which is built according to the traditional Korean wooden architecture, is receiving increasing attention because of increasing preference for diverse house types and environmentally-friendly houses. Accordingly, various studies are in progress as part of popularizing Han-oks. As one of the accomplishments of these studies, in open BIM study for 3D information exchange of Han-ok, a Han-ok member library using IFC-XML and an open BIM-based browsing module have been developed. It provides environment that enables data exchange between different BIM tools by containing geometry data and XML link data in IFC, which is a neural format, and parametric data in XML, to supports Han-ok design. However, to produce Han-ok members with XML, a specialist with expertise must perform coding, and it takes a long time for coding one member of Han-ok because of the hard coding method. To improve this issue, this study aims to develop an IFC-XML Automatic Description System for non-experts who do not have knowledge in coding. This study will enable non-experts to create various Han-ok members by in XML by using the Automatic Description System. Therefore, we can expect to continue building 3D Han-ok member library based on open BIM.

The purpose of this study is to support han-ok design for supply and popularization of han-ok using parametric design, To achieve this, represent design knowledge of han-ok components based on parametric rules on the basis of modeling principles and geometric association of han-ok to use various computer environment. This is realized to extract design DNA of shape and non-shape through meta modeling that be able systemically to describe information. In addition, construct the 3D Parametric model of han-ok component using this knowledge.

본 연구의 목적은 정신지체 학생의 구강건강 실태 및 치아우식 활성도를 평가하여, 학생들의 구강건강 증진을 위해 필요한 교육 방안을 모색하고, 실제적인 구강건강 관리 향상을 위한 기초 자료를 마련하고자 하는 것이었다. 광주광역시 소재 S 정신지체특수학교 유아부부터 고등부까지의 학생을 대상으로 조사를 실시하였다. 구강건강실태를 평가하기 위한 구강검사는 213명에 대해 시행하였으며, 치아우식활성도 검사는 197명에 대해 시행하였다. 치아우식활성도 평가를 시행한 197명의 정신지체 학생 중 우식활성이 고도인 학생은 33명(16.77%)으로 나타났으며, 13세 이하가 그 이상의 연령에 비해 치아우식활성도가 높았다. 치아우식활성도의 경중도와 치은염 유무와는 관련성이 없는 것으로 나타났다. 정신지체 장애학생의 치아우식활성도 경중과 치아우식경험지수와의 상관성을 평가한 결과, 치아우식활성도가 증가할수록 우식경험치율과 우식경험치지수가 높은 양상을 보였으며, 특히 유치의 경우 우식경험유치율 및 우식경험유치지수는 치아우식활성도와 높은 상관성을 보였다. The purpose of this study is to evaluate oral health status, caries-inducing bacterial activity of the mental retardation students, and developing motivation method for improving oral hygiene management by clarifying the relationship between caries- inducing bacterial activity and oral health status of mental retardation students. Caries experience indices, caries susceptibility test, gingival health evaluation, and oral hygiene management and oral health survey were performed. Results were as follows: 1. The DMFT index of disabled students(12 years) was 2.07. 2. The gingival inflammation was occurred more frequently in older ages. 3. There also was a high positive correlation between caries incidences and the results of caries-inducing bacterial activity test especially in deciduous teeth. This result suggested that the Dentocult SM mutans test as a caries activity test is a reliable method for measuring the status of dental caries in mental retardation students. Because it would motivate the mental retardation students to care more actively for their oral hygiene if they learn how much dental caries-inducing bacteria are living in their mouth by observing the bacterial colony on the cultured test strip, it can become a possibly efficient educational tool for the mental retardation students.

This study was carried out to determine therapeutic the effect of ozonated water therapy on bovine pododermatitis. In addition, bactericidal effect of ozonated water on etiological agent of bovine pododermatitis was examined. The pathohistological examination for the pododermatitis, according to application with ozonated water and ozone ointment was investigated. Thirty healthy cattle were divided two groups(each of 15) : control group (povidone group), treatment group (ozone solution group). Various parameters were evaluated in terms of the lameness score, swelling score, lesion score, WBC count, neutrophil count, pathohistological finding, and antimicrobial action. The decrease of lameness and lesion score were shown in hoof lesions on 14 days after application of ozonated water. Significant decrease of swelling was shown in hoof lesions on 14 days 1 Corresponding author after application of ozonated water(p < 0.01). In hematological findings, WBC count revealed values within normal range. The number of neutrophils was slightly higher than that of normal, however, this was improved on 14 days after application of ozonated water. In pathohistological findings, recovery was rapid macroscopically and microscopically in the treatment with ozonated water on the hoof lesions and ozonated water was effective. In antimicobial action, bactericidal effect was observed in treatment with ozonated water on the hoof lesions and ozonated water was effective.

The colorectal carcinoma shows the highest incidence of cancer death in Korea. The colorectal carcinomas are diverse in their carcinogenesis, as some progress from polypoid adenoma to carcinoma while others occur de novo, or combined de novo and adenoma to carcinoma sequence. The searchs for the early biomarker of the colorectal carcinoma are important not only for the early detection of the cancer but also for the effective treatment. Brain type glycogen phosphorylase (BGP) is a kind of fetal isoenzyme frequently expressed in the various carcinoma, such as gastric carcinoma, renal cell carcinoma and colorectal carcinoma. In this study, the expression of BGP was evaluated in the colorectal carcinoma, normal appearing mucosa adjacent to the carcinoma and aberrant crypts foci (ACF) by immunohistochemistry using 70 cases of colorectal carcinoma. The results were as follows. 1. The BGP was expressed in 91.4% of 70 cases of colorectal carcinoma. 2. The expression rate of BGP accoarding to the location of the carcinoma was not different. 3. Seventeen percent of the colorectal carcinoma occurred by the polypoid adenoma-carcinoma sequence, while 60% of the cases occurred from de nove and 22.9% from combined polypoid adenoma-carcinoma sequence and de nove. 4. The BGP was expressed in 91.4% of normal mucosa adjacent to the carcinoma, while in 17.1% of normal mucosa for apart from the carcinoma. The BGP expressed in the above results suggest that the colorectal carcinoma arsie more frequently in de novo than polypoid adenoma-carcinoma sequence, which suggest that the pathogenesis of coloretal carcinoma in Korean might be different from that of western people. And the expression pattern of BGP in the colorectal mucosa could be early biomarker of carcinoma and the immunohistochemical stain for the expression of the BGP might be used for the early detection of the colorectal carcinoma.

Mathematical model based on the kinetic aspect of the intermittent aeration system with continuous inflow (IASWCI) was developed. This model is a dynamic model dealing with the overall relationship between biomass concentration and contaminants in a reactor and a dynamic model dealing with the behaviors of biomass and substrate in a reactor within one cycle time of the process. That is, the proposed model predicts the time dependent microbial cell, substrate and nitrogen concentrations. The verification showed that the experimental result from a lab-scale facility could be successfully simulated and predicted by the model. The estimation of kinetic parameters were calculated from interpretation of the experimental data by means of respirometric method of activated sludge behavior in the batch reactors. This model is useful for further understanding of biological wastewater treatment kinetics by intermittent aeration system and may serve as a valuable design aid for practicing engineering.
