This study was performed to identify the significant variables affecting Follow-up after psychiatric consultation in General medical units and the trends of psychiatric consultation at the Hallym University hospital in Chunchon. Subjects of this study were 107 patients from April 1, 1998 to August 31, 1998, who were referred for psychiatric consultation during hospitalization. The results were as follows ; 1) Referral rate of General medical units was 7.5% and ordered Gastroenterology, Cardiology, nephrology, Other part. 2) The rate of total follow-up was 58% and the rate of No-follow-up was 42%. 3) In the cases of referral timing over admission 8th days, the days hospitalized after consultation performed were lengthened, significantly. 4) Common reasons for no follow-up of consultation were 'early- discharge' and 'patient's unwillingness to psychiatric reconsult. 5) Significant variables affecting follow-up were 'treatment recommendation', 'concordance with psychiatric drug recommendation', 'concordance with laboratory recommendation', 'total days hospitalized', 'Days hospitalization after consult was performed' and 'referral reason'.

Purpose: We evaluated the short and long-term changes of intraocular pressure (IOP) and studied its risk factors in pseudoexfoliation (PEX). Methods: A total of 40 eyes that had been newly diagnosed with PEX from January 1, 1995 to December 31, 2007 were included in this study. Age, gender and accompanying systemic disease were recorded. In addition, the age, gender, number of antiglaucoma eye drops, history of cataract operation, and history of systemic disease were evaluated as risk factors for IOP elevation during the follow-up periods. Pre and post cataract operation IOP was checked to evaluate the effect of the cataract operation on IOP. Results: The risk factors for IOP elevation in patients newly diagnosed with PEX were old age and female gender. After treatment, a long follow-up period and number of eyedrops were risk factors for IOP elevation. The cataract operation had a one year IOP control effect, especially in cases where the pre operative IOP was greater than 21 mmHg. Over the long term, however, the IOP control effect of cataract surgery could not be determined. Conclusions: IOP increased as result of increased patient age. Phacoemulsification was a protective factor for IOP elevation and may be a good method for short-term IOP control.

Acetylene-ethylene($C_2H_2-C_2H_4$) assay was carried out to find the heterotrophic nitrogen-fixing activities and distribution of nitrogen fixers in eleven different soil series which are located in Kyeonggi province. Following are the summaries of this study. 1. Acetylene-reducing activities were higher in Gwanghwal, Mangyeong and Buyong series which are derived from fluviomarine deposite than in Yeongsan, Hamchang and Pyeongtack series which are observed from continental alluvial plain. The lowest activities are observed in Yecheon, Hoegog, and Jisan series which are situated in local valley region. 2. Estimated amouts of $N_2$ per annum fixed by $N_2$-fixing heterotrophs were about 3.2kg in fuluvio marine soils, 2.6kg in continental alluvial plain and 2.0kg/10a in local valley region, respectively. 3. Azotobacter and Beijerinckia were not detected in any of the ten different soil series except in Pyeongtaeg series. However, Clostridia, anaerobic nitrogen fixer, was detected in order of ${\times}10^2$. It is assumed that these population are not enough to contribute to the nitrogen supply by the biological fixation in paddy soil. 4. For the assesment of heterotrophic nitrogen fixation in paddy soil, it must be presumed that aerobes, anaerobes and phototrophs which can grow on nitrogen free media may greatly contribute for the asymbiotic netrogen fixation.

핵 및 방사능전 상황에서 방사선에 의한 인명피해를 줄이기 위한 방안으로서 유개호에 자철석이 포함된 중량 콘크리트의 적용 가능성을 확인해보았다. 이에 본 연구에서는 자철광 콘크리트의 방사선 차폐효과를 분석하기 위하여 감마선원을 사용하여 차폐실험을 진행하였고 실험조건과 동일한 몬테칼로 모델링도 하였다. 그 결과 자철광의 함량이 증가할수록 감마선에 대한 차폐효과가 향상됨을 확인할 수 있었다. 향후 자철광 콘크리트가 군사적 목적의 시설물에 적용될 경우 방사선 차폐 측면에서 효과를 얻을 수 있을 것이라 기대한다. The purpose of this research is to analyze the gamma ray shielding effect of heavy concrete containing magnetic aggregate and to confirm the applicability to the military protective facilities. In general, a military concrete structure protects combatants from bullets, and also it provides some radiation shielding. In this research, experiments were conducted using a Cs-137 source to check the gamma ray shielding effect. In addition, the Monte Carlo N-Particle(MCNP) modeling was applied to evaluate the gamma ray shielding effect of a military structure. As a result, as the concrete thickness increased, the shielding performance improved according th the linear attenuation law. With that, as the ratio of magnetic aggregate was increased, gamma ray shielding performance was also improved. Therefore, this research verified that the application of magnetic aggregate concrete to military facilities for radiation shielding purposes would be useful.

웹 서비스 코레오그라피를 이용한 자동 웹 서비스 컴포지션 시스템

이상규,한상용,Lee, Sang-Kyu,Han, Sang-Yong 한국정보처리학회 2008 정보처리학회논문지D Vol.15 No.1

웹 서비스와 SOA(Service Oriented Architecture)의 확산으로 웹 서비스 컴포지션의 대한 관심도 점차 커져가고 있다. 최근에는 보다 동적이고 지능적인 SOA 환경의 구축을 위해서 자동 웹 서비스 컴포지션에 대한 연구가 활발하게 진행되고 있다. 하지만, 아직까지 자동 웹 서비스 컴포지션에 관한 완전한 해결책은 제시되지 못하고 있으며, 기존의 연구에서는 여러 가지 문제점을 드러내고 있다. 문법적인 정보 기반의 자동 컴포지션은 잘못된 의미 연결로 인하여 컴포지션의 정확성을 떨어뜨린다. 또한 대부분의 연구에서는 추상적인 컴포지션 결과를 만들어내기 때문에, 실제로 실행하기는 어려움이 있다. 본 논문에서는 이러한 문제점들을 개선하기 위하여 웹 서비스 코레오그라피 기반의 자동 웹 서비스 컴포지션 시스템을 제안하고 있다. 제안하는 시스템에서는 컴포지션의 정확성을 향상시켰고, 보다 구체적인 컴포지션 결과를 만들어낼 수 있다. Web Services composition has gained a considerable attention because of the widespread use of the Web Services and SOA. Recently, various researches on automatic Web Services composition are on going to realize more dynamic and intelligent SOA environments. However, there is no complete solution for automatic Web Services composition now and previous researches have several problems. Automatic composition based on syntactic information has low correctness through incorrect semantic linking. Moreover, many researches make an process as the result of composition which is hard for actual execution. In this paper, improved automatic Web Services composition based on Web Services choreography is proposed. In this system, the correctness is improved and the result of composition is more concrete process.

이상규,서장선,고재영,Lee, Sang Kyu,Suh, Jang Sun,Ko, Jae Young 한국토양비료학회 1987 한국토양비료학회지 Vol.20 No.1

The aerobic heterotrophic bacteria in the histosphere associated with grasses (Gramineae, Caryphyllaceae, Crucifereae) and rice cultivars in saline and reclaimed saline paddy soils were varied with species and rice cultivars. The fraction of aerobic heterotrophic $N_2$-fixing bacteria to the total aerobic heterotrophic bacteria were averaged to eighteen percent in the histosphere of grasses and rice. Acetylene reducing activity of these bacteria were ranged from 1 to 24 n mole/tube/hr. Most of the bacteria strains were predominated of hydrogen utilizing bacteria. The majority of these bacteria were closed to Pseudomonas, Azospirillum, Klebsiella and Agrobacter.
