1970년부터 2002년까지 전국을 조사한 자료 중 외래도입어중인 M. salmoides가 포함된 군집을 대상으로 공존성 및 종간상관성에 대하여 논의하였다. 총 7,192개의 조사지역에서 M. salmoides가 포함된 군집은 46군집, 공존하는 어종은 72종으로 나타났다. 공존성이 높은 종은 Z. platypus, O, bidens, H. eigenmanin, S. japonicus coreanus의 순이었다. 종집단간 공존도는 M. salmoides - Z. platypus 집단, M. salmoides - C. auratus 집단, M. salmoides 집단을 포함하고 있는 군집내에서 7종이 그룹화되었다. M. salmoides가 포함된 군집내에서 O. bidens와 Z. platypuswlqeks 등 7개 종집단은 종간 상관성이 매우 높았으며(p<0.01), L. macrochirus와 C. cuvieri 집단 등 11개 종집단은 종상관성이 다소 높은 것으로 나타났다(p<0.05). 한국의 하천이 점차 호수성하천으로 변화된다고 볼 때, M. salmoides 집단의 조절대책이 필요하다. On the fish community including Micropterus salmoides population, introduced species in Korea, interspecific association through coexistence by presence-absence among species populations were discussed from the year of 1970 to 2002. In the total of 7,192 sampling stations in Korea, the community including Micropterus salmoides population were confirmed at 46 sampling sites, and coexistent fishes were 72 species. Fish species having high coexistence rate were Zacco platypus, Obsarlichthys bidens, Hemiculter eigenmanni and Squalidus japonicus coreanus populations in the order of their number. A association indices values between population were in the order of Micropterus salmoides-Zacco platypus, Micropterus salmoides-Carassius auratus, and Micropterus salmoides-Hemiculter eigenmanni population. Judging from the dendrogram according to association indices between species population, 7 species populations were clustered in the community including M. salmoides population. Being based on association values among species population in the community including M. salmoides population, 11 species population pairs including Lepomis macrochirus -Carassus cubieri etc. showed somewhat high significance (p < 0.05), and 7 species population pair including Zacco platypus-Obsarlichthys bidens etc. represented higher association among species population (p < 0.01). With the increasing of lake- river in Korea, it keenly need to take a regulation program of the Micropterus salmoides population.

Objectives : There is a increasing need to recruit and retain more psychiatrists who can plan and implement organized programs to work with chronic mentally ill patients in community settings. The aim of study is to discover what training is currently in place to prepare psychiatrist for work in "community" or "public" settings. Methods : Survey questionnaires were mailed to 85 residency training directors and 10 leaders of community mental health in 2005. Response rate was 75%. Results : Academic seminar about community mental health were not administered to residents in 63% of training hospitals. Forty one out of 64 training hospitals had community mental health rotation programs, Community mental health center (50%) and day hospital (36%) were the most common type of programs. Few general hospital had affiliation with community mental health programs. The amount of time for clinical rotation varied from less than three months part time to 6 months fulltime, with most frequent form of one day per week for three month in second or third year of psychiatry residents. Conclusion : Further steps are needed to improve residency training curricula and to encourage well qualified psychiatrist to choose careers in community psychiatry.

This paper presents a primary study for a new method of enhancing measurement using impedance analysis method, which is widely used for structure health monitoring. Many of skyscrapers, bridges, tunnels, which have been built up several years, and nearly reached their operating life due to aging crack, material deterioration, and so on. therefore, the health monitoring technique has obtained considerable attention. The goal of this research is to show basic information to evaluate structural health condition using piezoelectric sensors. The piezoelectric materials have various merits. It is easy to shape various forms and can be embedded on the materials more conveniently. Moreover, the excitation frequency can be changed and the piezoelectric sensors cost less. All these features make the piezoelectric-based system applicable to structural healthy monitoring. This work presents a study for the development of a practical and quantitative technique for assessment of the structural health condition by piezoelectric impedance-based technique associated with longitudinal wave propagation. To estimate the damage condition numerically, we suggest the evaluation method Cov (Covariance) and CC (Correlation Coefficient) in this paper.

본 연구에서는 부력저항용 영구앵커의 거동을 시공단계별로 구분하여 분석한다. 즉, 앵커의 두부에 하중계를 설치하여 앵커축력을 계측하였으며, 이 계측결과를 토대로, 앵커축력의 손실, 건물자중의 증가 및 외적조건 변화에 따른 앵커의 거동을 분석하였다. 영구앵커는 초기인장력에 비하여 Jacking Free시 인장력이 약 7% 정도 감소하며, 최종인장력은 약 15%정도 감소한다. 한편, 앵커의 초기인장력은 외력이 작용하지 않아도 PC 강선의 relaxation, 주입재 및 지반의 creep 등의 내적요인에 의하여 비선형적으로 감소되어 1차 수렴치에 도달하게 된다. 1차 흙되메우기 작업 기간동안 앵커축력은 흙되메우기에 따른 횡방향 토압이 증가 및 상부구조물의 자중증가로 인하여 감소된다. 그러나, 흙되메우기 작업이 중단된 기간동안 되메우기한 흙의 이완현상으로 횡방향 토압이 감소되며 이로 인하여 앵커축력이 증가하게 된다. 그리고, 되메우기한 흙속으로 지하수가 유입되어 부력이 증가하게 되므로 앵커축력은 증가하게 된다. 이때 앵커축력은 1차 수렴치까지 회복하게 된다. The behavior of permanent anchors for buoyant resistance is investigated at each construction stage. The prestressed anchor forces were measured by load cells which were attached to anchor head. On the basis of instrumentation, the loss of anchor force and the behavior of anchor by increment of structure weight and change of external condition were investigated. Prestressed anchor force at jacking free is decreased by about 7% than initial prestressed anchor force and decreased by about 15% finally. Although external forces does not act on the substructure, initial anchor force is decreased nonlinearly due to relaxation of PC strand and creep of grouting materials and soils. Also, anchor force was converged at the first convergent value. When first backfill was performed, anchor force was decreased due to increment of lateral earth pressure and superstructure weight. But, anchor force grew gradually during the period of breaking backfill by lowering of lateral earth pressure due to relaxation of soils. When groundwater inflowed into backfill soils, anchor force is slowly increased by uplift force below mat foundation. At that time, anchor force is recovered by the first convergent value.
