Church is one of organizations recognized not as corporation but as private association and therefore its identity and possession of properties must be confirmed by the general theories of the civil law in relation not to corporation but to private association. Different from corporation, the internal relations of private association is primarily regulated by the articles of association. When there is no article of association, ordinary resolution and provisions for incorporated association in the civil law are applied by inference. As for the debt of private association, all the members own it in a quasi-joint manner (article 275 and 278). For the last 50 years, the judicial precedents of the Supreme Court has permitted the partition of church for the Protestant church and ruled that the relationship of properties at the time of partition is the joint ownership by church members at the time of partition. This ruling is different from that of corporation and ordinary principles of law. However, a new judicial precedent (the Supreme Court, 2006. 4. 20, 2004다37775) prescribes that different from corporation, the partition of private association is not allowed. Thus, in order to settle the dispute of private association, the Supreme Court changes its traditional standpoint of allowing partition into denying it. This ruling seems to reflect the necessity of settling dispute above all.

Patients with schizophrenia have thinking disorders such as delusion or hallucination, because they have a deficit in the ability which to systematize and integrate information. therefore, they cannot integrate or systematize visual, auditory and tactile stimuli. In this study, we suggest a virtual reality system for the assessment of cognitive ability of schizophrenia patients, based on the brain multimodal integration model. The virtual reality system provides multimodal stimuli, such as visual and auditory stimuli, to the patient, and can evaluate the patient's multimodal integration and working memory integration abilities by making the patient interpret and react to multimodal stimuli, which must be remembered for a given period of time. the clinical study showed that the virtual reality program developed is comparable to those of the WCST and the SPM.

A two-phase Large Eddy Simulation(LES) has been conducted to investigate breakup and atomization of a liquid jet in a cross turbulent flow in a rectangular duct. Gas-droplet two-phase flow was solved by a coupled Eulerian-Lagrangian method which tracks every individual particles. Effects of liquid breakup models, sub-grid scale models, and a order of spatial discretization was investigated. The penetration depth in cross flow was comparable with experimental data by varying breakup model and LES scheme. SMD(Sauter Mean Diameter) distribution downstream of jet was analyzed.

This study was carried out to investigate the epidermal structure and types of stomata on the upper and lower surfaces of the leaves in six species and one variety belonging to Korean Crassulaceae. The shape of epidermal cells was polygonal, isodiametric, or elongated. The cell wall was thick, sinuous or deeply sinuous. The subsidiary cell wall was thin or mostly arched. The cytolith-containing cells were found in Orostachys japonicus. The distribution of stomata was more on the upper surface than on the lower surface in the leaves of O. japonicus and Sedum sarmentosum. The stomata in the other species were less on the upper surface than on the lower surface, and stomatal size was different in each species. The great majority of stomatal types was the helico-eumesogenous type. This type was subdivided into two, parahelico-eumesogenous type and diahelico-eumesogenous type by us on the basis of the angle of division of guard mother cell and the long axis of the last-formed subsidiary cells. Sometimes allelo-eumesogenous type as well as aniso-eumesogenous type was found. The tetra-eumesogenous type with four mesogenous subsidiary cells was rarely observed. It was observed that the varieties of aniso-eumesogenous type with one to three subsidiary cells and one helix of subsidiary cells were developed by the secondary division of subsidiary cells of aniso-eumesogenous stoma. The compound shape of helico-eumesogenous stomata was found. Five new kinds of stomatal types were observed as follows; the helico-tetra-eumesogenous type, the coallelohelico-eumesogenous type, the cohelico-allelo-eumesogenous type, the duplotetra-eumesogenous type, and the aniso-euperigenous type. These types were reported here in the vascular plants for the first time.

Background:Several reports have suggested that cytokine alterations could be related to the pathophysiology of schizophrenia. In this study, we measured plasma level of interleukin-12(IL-12), a proinflammatory T helper 1(Th1) cytokine and transforming growth factor-${\beta}1$(TGF-${\beta}1$), an anti-inflammatory Th3 cytokine before and after antipsychotic treatment in schizophrenic patients. Methods:The plasma concentrations of IL-12 and TGF-${\beta}1$ were measured by using quantitative ELISA in 23 schizophrenic patients and 31 normal controls at admission and 8 weeks later. The psychopathology was measured by Brief Psychiatric Rating Scale(BPRS). Results:IL-12 and TGF-${\beta}1$ levels were significantly higher in schizophrenic patients than in controls before treatment. At the 8 week of treatment, the TGF-${\beta}1$ levels returned to control values, while IL-12 levels were not significantly changed. There were no significant correlations between the changes of BPRS scores and the changes of IL-12 or TGF-${\beta}1$ levels in schizophrenic patients. Conclusion:Cytokine abnormalities in schizophrenia might be involved in the pathophysiology of the illness. It is possible that TGF-${\beta}1$ plays an important role in the schizophrenia.

Objectives : The hypothesis that the brain is a nonlinear dynamical system exhibiting deterministic chaos has offered new perspectives to the investigation of information processing in the brain of schizophrenic patients. It seemed worthwhile to estimate nonlinear measures of the electroencephalogram (EEG) in positive and negative schizophrenics, because nonlinear measures might serve as indicators of the specific brain function in schizophrenia according to specific psychopathologies. Method : Previous studies which estimated the chaoticity in the brain of schizophrenia with nonlinear methods recorded the EEGs at limited electrodes, so we tried to record EEGs from 16 channels for nonlinear analysis in 8 positive and 9 negative schizophrenics and 8 healthy control subjects. We employed a new method to calculate the nonlinear invariant measures. For limited noisy data, this algorithm was strikingly faster and more accurate than previous ones. Results : Our results showed that the patients with negative schizophrenia had lower the first positive Lyapunov exponents ($L_1$) than the positive schizophrnics and control subjects at $T_3$ lead. Positive symptoms were positively correlated with $L_1$ in $C_3,\;O_1$ leads, and negatively correlated with $C_4$ lead. Conclusion : These results suggest that if clinical variables such as psychopathology or neuroleptic medications would be well controlled, the nonlinear analysis of the EEGs in patients with schizophrenia seems to be a useful tool in analyzing EEG data to explore the neurodynamics.

In this study, we attempted to determine the precise patterns of protein synthesis during the second cleavage in mouse. F1 hybrid 2-cell embryos showing a highly synchronized cell cycle and outbreed ICR strain 2-cell embryos were used. The patterns of protein synthesis during the second cleavage showed the sequential changes in the F1 hybrid and ICR strain 2-cell embryos. Moreover, we examined the effects of mitotic and transcriptional inhibitors such as colcemid and a-amanitin on the protein synthesis in the late 2-cell embryos of ICR strain. Treatment of colcemid (0.1mg/ml) blocked the second cleavage, but did not affect on the change of protein synthesis. However, treatment of a-amanitin induced the synthesis of two set of polypeptides without affecting on synthesis of other proteins and cleavage. It thus seems that the appearance of a-amanitin-sensitive proteins may be not involved in the second cleavage. Therefore, these results indicate that the second cell cycle in mouse embryos appears to be regulated at post transcriptional level, presumably independent on the expression of embryonic genome. 본 연구는 생쥐 배아의 2세포기 분열과정중 단백질 합성양상과 단백질합성에 미치는 colcemid와 $\alpha$-amanitin의 영향을 조사하였다 이를 위하여 체내 수정된 ICR strain의 2세포기 배아와 매우 일치된 초기배아 분열양상을 보여주는 체외 수정된 F1 (C57BL x CBA) hybrid 2세포기 배아를 사용하였다. 두 종류의 2세포기 배아에서 단백질 합성은 분열단계에 따라서 매우 일치된 변화를 보여 주었다. 또한 유사분열 억제제인 colcemid (0.1mg/ml)의 처리는 2세포기 배아분열을 억제하였으나, 단백질 합성에는 아무런 변화를 주지 못하였다. 그리고 후기 2세포기 배아에 전사 억제제인 a-amanitin (100mg/ml)을 처리하였을 때 세포분열이나 다른 단백질의 합성에는 아무런 영향이 없이 단지 두개의 단백질의 합성만을 유도하였다. 이는 아마도 a-amanitin의 stress효과에 기인하는 것으로 추측된다. 따라서 생쥐 2세포기 배아의 분열과정은 배아게놈의 유전자 발현과는 무관하게 이미 합성되어 존재하는 mRNA에 의하여 조절되는 것으로 사료된다.

A new fragmentation model, called the GRS (the generation model of weathered residual soils) model, was proposed in this study, This model could identify the formation of a residual soil. This model is based on the phenomena that as the soil was weathered more highly, soil particles were smaller and pores were more expanded simultaneously. The possibility of fragmentation, $P_F,$ which was based on the fractal theory, was introduced in this model. There were some fundamental notions in the GRS model that soil particles were generated as the rock is fragmented, and the fragmentation of the rock was performed step by step. The $P_F,$ of the rock was not constant at each fragmentation steps. As a result of application on the GRS model, there were more residue where $P_{Fi}s$ were small at any particle size. There was a S-shape of PSD curve at the concave shape of $P_{Fi},$ and the PSD curve goes to a gaped graded curve at the convex shape of $P_{Fi}.$ The shape of PSD curve was concave in the case of small $P_{Fi}s.$ The value of $P_{Fi}$ increased with the coefficient of uniformity $(C_u)$ and the fragmentation fractal dimension $(D_r),$ but had no relation with the coefficient of gradation $(C_C)$.

The effects of X-irradiation on the mitotic activity, the chromosome aberration and the DNA synthetic pattern in synchronized human kidney cells treated with 5-AU were measured in the present experiment. When 5-AU was added, mitotic activity was markedly suppressed. After removal of the cells from the chemical, its activity proceeded synchronouly and reached peaks at hours 10. In 5-AU+100R groups, it was observed the X-ray caused mitotic delay, the irregularity of the time when mitotic peak appeared and the inhibiton of mitotic activity. In the control group, chromosome aerrations per cell was 0.030, whereas 0.147 in 5-AU treated group. In 5-AU+100R and 5-AU+200R groups, chromosome aberrations per cell were 0.583 and 0.669 respectively and the average chromosome aberrations per cell per R was 0.0035. 5-AU increased the frequency of labeled metaphases together with labeling intensity, and this is thought to be due to the accumulation of cells by 5-AU at S stage. On the contrary, X-ray decreased the labeling intensity and the frequency of labeled metaphases.

본 연구에서는 정신분열증 환자들이 정서상태를 개념화하고 얼굴표정을 통하여 타인의 정서 상태를 판단하는 과정을 정상인과 비교하였다. 연구1에서는 만 19세-46세의 정신분열병 환자 19명에게 정서 관련 형용사 15개로 구성된 105개의 형용사 쌍에 대하여 유사성을 평정하도록 하여 MDS로 분석한 결과, 쾌/불쾌와 각성의 두 차원이 일관되게 보고되고 있는 정상집단과는 달리 정신분열병 집단의 자료에서는 쾌/불쾌 차원만이 뚜렷하게 나타나고 각성 차원은 얻어지지 않았다. 연구 2에서는 다양한 정서를 표현한 얼굴 사진 28개를 정신분열병 환자 30명과 대학생 31명에게 제시하고 각 사진의 인물이 경험하고 있는 내적 상태를 쾌/불쾌와 각성의 두 차원에 대하여 각각 7점 척도로 평정하도록 한 결과 정신분열병 집단은 대학생 집단에 비하여 쾌/불쾌 차원에서는 보다 긍정적으로 평정하는 경향이, 각성 차원에서는 상대적으로 낮게 평가하는 경향을 나타냈다. 특히 부정적이고 각성 수준이 높은 내적 상태를 표현하는 사진 자극에 대하여 정신분열병 환자 집단이 각성수준을 과소평가하는 경향이 두드러지게 나타났다. 이와 같은 결과를 종합하여 볼 때, 정신분열병 환자들은 정서상태의 개념화 과정에서 각성 차원에 대하여 상대적으로 낮은 민감도를 보이고 있으며, 특히 부정적인 정서상태를 표현하는 얼굴들에 대란 판단에서는 각성 차원을 과소평가하여 높은 각성수준을 나타내는 표정과 낮은 각성수준을 변별하는데 어려움을 보이는 것으로 해석될 수 있다. 본 연구의 결과는 정신분열병 환자들은 자율신경계의 높은 각성 수준으로 인하여 각성 수준을 더 높일 가능성이 있는 자극을 회피하는 경향이 있다는 Mednick의 가설과 일관되는 결과로 이들의 각성 수준에 대한 낮은 민감도는 방어적인 회피성향의 지속에 따른 둔감화의 결과로 해석될 수 있다. 효과는 GSR를 비롯한 자율신경계지표에서 잘 반영되었다.^2$=.792가 되었다. 설명되는 누적분산값은 67.18%였다.주관적 평가의 결과와 객관적 평가 결과를 이용해 마직물의 태를 평가하는 산출식을 제시하였다. 태 평가치의 경우 16가지 특성치를 모두 넣는 방법과 stepwise 방법, 또 Kawabatark 사용한 순차적 군 회귀법의 세가지 방법의 회귀식 중 16가지 특성치를 모두 넣는 방법의 결정계수가 가장 높았다.tosterone농도는 107.7$\pm$12.0 pmol／l이었고, 남성의 타액내 농도는 274.2$\pm$22.1 pmol／l이었다. 이상의 결과로 보아 본 연구에서 정립된 EIA 방법은 RIA를 대신하여 소규모의 실험실에서도 활용할 수 있을 것으로 사려된다.또한 상실기 이후 배아에서 합성되며, 발생시기에 따라 그 영향이 다르고 팽창과 부화에 관여하는 것으로 사료된다. 더욱이, 조선의 ${\ulcorner}$구성교육${\lrcorner}$이 조선총독부의 관리하에서 실행되었다는 것을, 당시의 사범학교를 중심으로 한 교육조직을 기술한 문헌에 의해 규명시켰다.nd of letter design which represents -natural objects and was popular at the time of Yukjo Dynasty, and there are some documents of that period left both in Japan and Korea.
