철골 구조물에서, 보-기둥 접합부의 설계와 구조해석은 건물 전체의 안정성 확보와 경계성에 큰 요인으로 작용한다. 일반적인 보-기둥 접합부의 해석은 완전한 강접합이나 핀 접합으로 가정하여 수행하고 있으나 실제적으로는 휨에 대하여 어느 정도의 강성을 갖고 있는 반강접 접합부가 자주 적용되고 있다. 이 연구에서는 비선형 구조해석 프로그램인 ADINA에 적용하여 반강접 접합부의 강성을 밝혀내며, 7가지 형태로 분류된 접합방법에 대해 강성을 비교 분석하고 실험결과로 검증하여 ADINA의 적용방법의 제시와 함께 그 타당성을 입증하였다. The conventional analysis and design of steel frameworks usually carried out under the assumption that the connections joining the beams to the columns are either fully rigid or ideally pinned. In practice, the most steel frames have been composed of the semi-rigid connections because the most connections exhibit a certain degree of flexibility under loads. In this research, the prediction of rotational stiffness of semi-rigid connection using common structural analysis program, ADINA(Automatic Dynamic Incremental Nonlinear Analysis) can be performed, without carrying out experiment or analytical model. The comparison of rotational rigidity about for seven types of connection was shown, also, the connection types using both angle and end-plate, are testified by test data and analytical model.

The effect of different temperature, salinity and pH on survival rate of Urechis unicinctus's swimming embryo was examined to develop the method for the efficient seed production. In addition to, this study was designed to investigate the possibility of pollutant marker diagnosis of marine pollutions by the change in different temperature, salinity and pH. Treatment was carried out whit different temperature (5˚C, 10˚C, 17˚C, 20˚C, 25˚C,), salinity(0‰, 10‰, 20‰, 30‰, 34‰, 40‰) and pH(4, 6, 7.2, 8.2, 9.2, 10). All the swimming embryo of the temperature experiment was survived within all experiment section, but the others experiment were not. At the temperature-shock and tolerance experiment ranging from 5˚C to 25˚C the survival rate was occurred: 75%, 95%, 100%, 100%, 50%, at the ph-Shock experiment ranging from 4 to 10, the survival rate was occurred: 0%, 50%, 85%, 100%, 60%, 0%, at the pH-tolerance experiment ranging 4 to 10 the survival rate was occurred : 0%, 75% 90%, 100%, 80%, 0%, and at the salinity-shock experiment ranging from 0% to 40% the survival rate was occurred : 0% 10% 90% 95% 100% 0% , at the salinity-tolerance experiment ranging from 0% to 40% , the survival rate was occurred : 0% 0% 90% 100% 100% 0%. These results suggest, that the survival rate of larvae of Urechis unicinctus was the highest at 17˚C, 34%. pH8.2 and this Urechis unicinctus could be live at the zone of euryceious and zone of euryhalines

These days, the underwater excavation and the piling work have been commonly used to reclaim land and to build a breakwater. As the piling work generates high underwater sound pressure in all direction, various kinds of marine organisms are largely affected even if they live a long distance from the piling work. Therefore, this paper describes the relationship between the behavior of abalone(Haliotis discus hannai) of 50cm long and the environmental noise level with vibration due to the piling work. We have separated the research into two parts. The one is continuance impact, the other is intermittent impact. The following are the results obtained from the present investigation: Comparing 0.5cm/sec vibration with 50dB noise and 0.9cm/sec vibration with 60dB, the previous one show a faster reaction speed than the later one. Futhermore the later one showed that pulling up on their shell, in order to avoid the epidemic, moving around, small organisms are included to hide under big organisms, alerting posture. However we couldn't find a consistent standard in our research.

This study was performed to characterize the seasonal fluctuation of water quality and sediment environment from April, 2001 to November, 2001 in Gamak bay. Which was a productive area, but recently its fisheries conditional have been deteriorated because of increasing waste-water from municipal area, industry and autochthonous pollution by farm industry. In the survey of seawater quality, DO and COD concentrations were lowest in bottom layer at summer, but DIN and DIP contents were higher than those in surface layer. Eutrophication indices mean that eutrophication area move from south to north entrance via northern-west inner area with seasonal change from summer to autumn. In the survey of sediment environment, ignition loss(IL), chemical oxygen demand(COD), DIN and Dip were in the range of 3.8~15.7%, 10.3~60.6mg/g-dry, 5.053~1.810mg/ℓ and 0.065~0.324mg/ℓ , respectively. COD in sediment were highest at winter and spring. And, they were higher than sediment standard in the south inner area, which mean heavily polluted conditions with organic constituents.

This study was coducted to describe the distribution and appearance pattern of macrobenthos in Kamak Bay, the southern coastal of Korea. Sampling was perfound seasonally using Van Veen grab(0.1㎡) from April 2001 to December 2001. A total of 22 macrobenthic species occured: Bivalvia accounted for 12 species(55%), and Mollusca 5 species(23%). The mean density of macrobenthos was 153.9ind./㎡, a major dominant species were a Bivalvia, Paphia undulata(28.3ind./㎡), and a Cirripedia, Chthamalus challengeri(5ind./㎡), which frequency occur in the costral area. These species showed very low density at station 1 in the Kamak Bay.

한국판 소아 양극성장애 설문지 2.0(Child Bipolar Questionnaire 2.0)의 신뢰도 및 타당도 연구

Objectives : The Child Bipolar Questionnaire 2.0 (CBQ 2.0) is a rapid screener with a Core Index subscale of symptom dimensions frequently reported in childhood-onset bipolar disorder (BD) and scoring algorithms for DSM-Ⅳ BD, with and without ADHD, and the proposed Narrow, Broad, and Core phenotypes. This report provides preliminary data on the reliability and validity of the CBQ 2.0-Korean version. Methods : Core Index subscale to effectively predict diagnostic classification by structured interview was assessed using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version-Korean Version (K-SADS-PL-K). Test-retest and inter-rater reliabilities of the CBQ 2.0 were assessed. Correlation of Korean Child Behavior Checklist (K-CBCL) with CBQ 2.0-Korean version was performed. Results : The CBQ 2.0 screening algorithms performed with a specificity of 66.7% and a sensitivity of 94.7% in classifying subjects with K-SADS-PL-K diagnosis of BD vs. no BD. The Core Index subscale had “good” agreement with K-SADS-PL-K diagnosis (Kappa=0.676) in identifying BD, ADHD-only, and no diagnosis. Conclusion : This preliminary data is from a sample derived from the child and adolescent psychiatric clinics, further validation is needed with community based samples in which childhood-onset BD is rarer and diagnoses more diverse. The CBQ 2.0-Korean version shows potential for rapid and economically feasible identification of possible childhood-onset BD cases as defined by DSM-Ⅳ criteria as well as by alternate disease phenotypes.

This study was carried out to produce the seeding of the larvae and juvenile of black sea bream, Acanthopagrus schlegeli in terms of artificial hatching, feeding behavior and growth rate in each factor. Total length of black sea bream larvae hatched was 2.57±0.35mm and after 50 days, total length was 22.08±3.74mm, 49.7% in survival rate. This research was conduced to confirm the effect of tributyltin and 2,4-dinitrophenol on the sex differentiation in Black Sea bream, Acanthopagrus schlegeli. Fish were reared of oral administration of tributyltin at 0.05, 0.5, 5㎍/g and 2,4-dinitrophenol at nominak concentration of 0.05, 0.5, 5, 50㎍/g diet from 156 days to 185 days after hatching. In the process of the differentiation until 156 days after hatching, gonads were composed testis. In contrast, 185 days after hatching, testis were composed of a number of spermatogonia and sperm duct. The female in the control in which sex differentiation of Acanthopagrus schlegeil was normally conducted was 100%. The experimental unit of estradiol-17β, it was 100% in 0.05㎍/g diet concentration, which was similar to the sex ratio of the control. And it was 100% in 0.5㎍/g diet concentration. In each experimental unit with 5, 50㎍/g diet concentrations, every individuals of them differentiated to males. About the experimental unit of tributyltin, the females were 100%, 100%, 100%, 100% and 100% in 0.05㎍/g, 0.5,㎍/g, 5㎍/g and 50㎍/g diet concentrations, respectively. About the experimental unit of 2,4-dinitrophenol, the males were 100% tn 0.05, 0.5, 5, 50㎍/g diet concentrations, respectively.
