윤규석,김덕언,최태열 대한감염학회 1993 감염 Vol.25 No.1

An immunotyping of 27 strains of Chlamydia trachomatis isolated from patients with non-gonococcal urethritis or pelvic inflammatory diseases in Korea was achieved in dot-enzyme linked immunosorbent assay (dot-ELISA) with monoclonal antibodies. Monoclonal antibodies were produced with standard techniques by immunization of Balb/c mice and fusion with SP 2/0 myeloma cell. Seven type-specific (D,E,F,H,I,J,L₂), 2 subspecies-specific (B-complex, C-complex) and species-specific (HMC 1-1) monoclonal antibodies were used for immunotyping. Immunotyping of 12 control strains and 27 clinical strains isolated in Korea was studied by using dot-ELISA. Species-specific (HMC 1-1) monoclonal antibody reacted with all control strains and 27 isolated. Subspecies-specific (B-complex) monoclonal antibody reacted with B/HAR-36, Ba/Aphach-2, D/UW-3Cx, E/Bour, LGV type Ⅰ/440, LGV type Ⅱ/CDC control strains and 19 isolates. Type-specific monoclonal antibody of D was reacted with D/UW-3/Cx control strain and 10 isolates. E type-specific monoclonal antibody racted with E/Bour control strain and 6 isolates. F type-specific monoclonal antibody reacted with 5 isolates. Three isolates which racted with subspecies-specific monoclonal antibody didn't react with any type-specific monoclonal antibodies. Subspecies-specific (C-complex) monoclonal antibody reated with A/HAR-13, C/CDC, H/UW-43/Cx, J/UW-36/Cx control strains and 2 clinical isolates, but the isolates did not react with any type-specific monoclonal antibodies. One of 27 clinical isolates reacted with any type-specific monoclonal antibodies. One of 27 isolates reacted with species-specific (HMC 1-1) monoclonal antibody didn't react with any other subspecies-and type-specific monoclonal antibodies. In conclusion, the major immunotypes of C.trachomatis from urogenital system in Korea were D, E and F, and dot-ELISA with monoclonal antibody may contribute for immunotyping as a simple and specific technique.

Generally, the pile foundation is used in the form of the group pile. Pile foundations used in coastal structure, power transmission tower, and abutment are considered as active piles that are affected by the lateral load. So in this paper, we conducted a model test on the sand ground with 3×3 arrangement by changing the relative density and the spacing ratio of group pile. The result of the study is following : In group piles, as the displacement of top is increasing, the lateral load capacity also increases. In group piles, when the relative density is constant, as the spacing ratio is increasing, the lateral load capacity increases. When the spacing ratio is constant, as the relative density is increasing, the lateral capacity load increases. The efficiency of group pile is increasing as the spacing ratio increases. And the efficiency of long group piles is constant, but the efficiency of short group piles is decreasing as the relative density increases. In the case of short group piles, the limit pile spacing ratio didn't appear. But in the case of long group piles, the limit pile spacing ratio is observed about 5D.

실시간 분산 환경 감시를 위한 TMO 모델의 연구

정윤석,김태완,장천현 건국대학교 산업기술연구원 2005 건국기술연구논문지 Vol.30 No.-

We need an additional monitoring tool to observe a TMO model-based system because the conventional tools ae not based on the monitoring concept. Some studies have been conducted to develop a monitoring tool. But it is hard for them to support a distribued monitoring because they did not use a data sharing and delivery mechanism provided by the TMO model. To solve this problem, in this paper, we propose a TMO monitoring model which the TMO model and a monitoring concept are combined in. The model is composed of some components to support monitoring, and it guides the middleware to take all the monitoirng functions. Thus, a user can get monitored data provided by the middleware without any efforts. In addition, in this paper, we propose the MODS and MDC which are mechanisms to share or deliver the monitored data in distributed environments. These can resolve problems with conventional data stores used by the legacy monitoring tools, and provide a fundamental data management scheme to monitor several systems in distributed environments. The TMO monitoring model, MODS, and MDC can be used for a TMO system monitoring, performance evaluation, and monitoring tool development.

Objective : Allergic rhinitis is one of the most common diseases in the field of otorhinolaryngology. Correct diagnosis for allergic rhintis is important for its optimal management. Many stuides have been reported for the diagnosis with allergens. This study was performed to identify the relationship between MAST. the skin test, and the nasal provocation test. We attempted to find an appropriate diagnostic method for finding causative allergens. Method : We reviewed the medical records of patients with allergic rhinitis symptoms and physical findings from August 2001 through July 2002 at Inha University Hospital. We selected 197 patients who were examined with MAST, the skin prick test, and the nasal provocation test. The relationship between these tests was detremined with SPSS (Ver 10.0). Results : There was a significant correlation between MAST and the skin prick test (F<.05). There were also significant correlations between MAST and the nasal provocation test, and between the skin prick test and the nasal provocation test(F<.05). Conclusion : MAST might be a useful diagnostic method for finding causative allergens, especially in children and patients with skin hypersensitivity and other skin disorders.

광고 대행사와 제작사의 사회연결망 분석 : 광고 대행사의 소유형태와 규모가 거래관계에 미친 영향

홍석민,윤태일,이기홍 한국방송광고공사 2005 광고연구 Vol.0 No.66

이 연구는 광고시장개방이 한국 광고산업에 실질적으로 미치는 영향을 규명하기 위해서, 2002년 산업자료를 바탕으로 대행사와 방송광고 제작사 사이의 거래연결망을 분석해보았다. 특히 사회연결망 분석(Social Network Analysis; SNA)의 틀을 원용하여, 광고 대행사의 소유형태(다국적 대행사 대 국내 대행사) 및 규모(상위권 대행사 대 중위권 대행사)에 따라 연결망에 차이가 있는가를 통계적으로 검증해 보았다. 분석결과 다국적 대행사가 국내 대행사보다, 그리고 상위권 대행사가 중위권 대행사보다 거래연결망의 구조 자체가 더 밀도가 높고 다양하여 효율적인 것으로 나타났다. 또, 이들 대행사의 중앙성(centrality) 지표가 높아 제작사와의 거래연결망에서 더 중심적인 위치를 차지하는 것으로 밝혀졌다. 특히 중앙성 지표에 대한 대행사의 소유형태와 규모 사이의 상호작용 효과는 연결정도 중앙성, 사이 중앙성, 위세 중앙성 3가지 지표 모두에서 나타났다. 또 중앙성 지표가 높은 대행사일수록 방송매출액, 순위, 종업원 수, 1인당 취급액 등의 기업성과 관련 지표에서도 우수성을 나타냈다. 이러한 분석결과에 대한 이론적 실무적 함의와 국내 광고산업의 경쟁력 제고를 위한 제언사항을 논의했다. Prior studies regarding Korea’s advertising industry have almost exclusively examined practitioners’ perceptions of changes in the advertising industry as global advertising agencies launched business in Korea. This study on Korea’s advertising market, however, used a unprecedented approach by looking into the relationship between advertising agencies and advertising production companies through the framework of social network analysis. It tested if there existed significant difference by ownership(global vs. local) and size(the largest 10 agencies vs. the rest) in maintaining business networks. Results from this study indicate that the global advertising agencies show stronger network density and centrality, more diversification, and more efficiency than the local advertising agencies in terms of inter-organizational relationship. Additionally, the interaction effect existed between the ownership and the size of advertising agencies by centrality index. Finally, the higher centrality index among agencies is, the higher billing and ranking are. The end of the paper offers further theoretical and practical implications of the analyses and suggestions to improve Korean advertising agencies’ business performance.
