Objectives : The goal of this study was to investigate the effect of Moutan Cortex as antidepressant in forced swimming test(FST) model. Methods : The expressions of corticotropin-releasing Factor(CRF), c-Fos and tyrosine hydroxylase(TH) were measured with immunohistochemical method at paraventricular nucleus (PVN), locus coeruleus(LC) and ventral tegmental area(VTA). Results : The duration of immobility in the forced swimming test was significantly decreased in the Moutan Cortex 100 mg/kg treated group in comparison with the control group(p<0.01). CRF and c-Fos expressions at PVN were decreased in the Moutan Cortex 100mg/kg treated group in comparison with the control group. But only the expression of c-Fos was shown the significance(p<0.05). TH expressions at LC and VTA were significantly decreased in the Moutan Cortex 100mg/kg and 400mg/kg treated group in comparison with the control group(p<0.001). Conclusion : According to the results, Moutan Cortex has the antidepressant effect by showing the reduced immobility through the reduction of c-Fos expression at PVN and the reduction of TH expression at LC and VTA.

Purpose : The purpose of this study was to investigate the performance level of functional independence of the stroke patient. Methods : In order to find out the functional independence of stroke patient, 160 peoples, 80 peoples in a large city and 80 peoples in small-to-medium sized city, were questioned. Result : The results of this study were as follows: 1. Functional independence level due to social factor; The comparison of functional independence level between two groups showed significant difference in educational level, religion, family member, vocation, and medical fees(P<.05). However, the two groups did not show significant difference in spouse. 2. Functional independence level due to environment factor; The comparison of functional independence level between two groups showed significant difference in place of residence and residental environment(P<.05). However, each group did not show significant difference. Conclusion : These results suggest that realization of stable housing, educational level, various physical activities, and diversified family members is essential. Also, stable environment and social satisfaction are needed to maintain and improve the health of patient.

This study used the questionnaire method to find out the golf factor comparison and purchase inclination according the golfers' demographic characteristics. The golf factor comparison according to the Gyeongnam golfers' demographic characteristics was performed with cross analysis and $X^2$ verification, the purchase inclination with T verification and analysis of variance. And the Golfs' factor relation according to total income was performed with cross analysis and $x^2-test$. The golfers' demographic characteristics showed a significant difference in gender, educational background and occupations. The participation purposes of playing golf for men were as a hobby, relations and business. And the participation purposes of playing golf for women were as a hobby and health. The higher age was, the more the golf career was for both men and women. In the factor of marital status, unmarried people play for a hobby and married people play for better relations and business. In the factor of gross income, male golfers varied in the gold career and monthly playing times. Female golfers varied in the golf career. Regardless of gender, the higher the income was, the more the golf career was. In the comparison of buy behavior according to the golfers' demographic characteristics, male golfers showed a significant difference in ostentation and fashion according to the monthly purchase of golf-wear. The group that spends more on the monthly purchase of golf wear was higher than the group that spends less on the monthly purchase of golf wear. Unmarried golfers showed more ostentation tendency that married golfers.

The results of stand and field testing of a combustion chamber for a heavy-duty 150 MW gas turbine are discussed. The model represented one of 14 identical segments of a tubular multican combustor constructed 1:1 scale. The model experiments were executed at a lower pressure than that in a real gas turbine. Combustion efficiency, pressure loss factor, pattern factor, liner wall temperature, flame radiation, fluctuating pressure and NOx emission were measured at partial and full loads for both model and on-site testing. The comparison of these items in the stand and field test results led to has the development of a method of calculation and the improvement of gas turbine combustors.

To better estimate the non-Gaussian extreme wind pressures for high-rise buildings, a data-driven revised Hermitetype peak factor estimation model is proposed in this papar. Subsequently, a comparative study on three types of methods, such as Hermite-type models, short-time estimate Gumbel method (STE), and new translated-peak-process method (TPP) is carried out. The investigations show that the proposed Hermite-type peak factor has better accuracy and applicability than the other Hermite-type models, and its absolute accuracy is slightly inferior to the STE and new TPP methods for non-Gaussian wind pressures by comparing with the observed values. Moreover, these methods generally overestimate the Gaussian wind pressures especially the STE.

The Bayes factors with improper noninformative priors are defined only up to arbitrary constants. So it is known that Bayes factors are not well defined due to this arbitrariness in Bayesian hypothesis testing and model selections. The intrinsic Bayes factor and the fractional Bayes factor have been used to overcome this problem. In this paper, we suggest a Bayesian hypothesis testing based on the intrinsic Bayes factor and the fractional Bayes factor for the comparison of two lognormal variances. Using the proposed two Bayes factors, we demonstrate our results with some examples.

This study provides a basis for the development of lesson plans and teaching programs associated with the appearance in the adaptation of interpersonal relationships. This study was analyzed adolescents' body comparison and body satisfaction related in the adaptation of interpersonal relationships, and the effectiveness of self-esteem mediation. The survey was conducted among 587 adolescents in Gwangju. The data was analyzed using SPSS ver. 19.0 for Windows: frequency, means, factor analysis, Cronbach's ${\alpha}$, t-test, analysis of variance, Pearson correlation analysis, and regression analysis. The results indicated that body comparison and body satisfaction effected the adaptation of interpersonal relationships among adolescents consequently, it is necessary to develop lesson plans and teaching programs related to awareness, and improve appearance. A body comparison with similar aged people did not affect self-esteem; however, it is necessary to improve body satisfaction because it affects self-esteem. Self-esteem was also the mediating role between the adaptation of body satisfaction and interpersonal relationships, sub-factors, adaptation of relationships with friends, adaptation of relationship with teachers, adaptation of relationships with parents. It is important that body satisfaction and self-esteem is key factor in planning training programs, and improving the capacity of adolescents adaptation of interpersonal relationships.

The power comparison techniques have implemented power measurements, in which a power comparator is used to balance ac against a dc power obtained from known values. The developed power standard system using the comparison techniques consists of dc sources, ac source, control switches, resistive voltage dividers, resistive shunts and a power comparator. The total uncertainty of the power standard system was proved by analysis of the component instruments. Its expanded(k=2) uncertainty is evaluated to be less than 30 uW/VA at unit power factor and 42 uW/VA at power factor 0.5

In this paper, we develop the Bayesian multiple comparison procedure for the normal model. The procedure which we suggest is based on the fractional Bayes factor of O'Hagan (1995). We apply our procedure to normal populations, when noninformative prior is assumed to the model parameters. We derive explicit form of Bayes Factors when the number of populations is greater than 3. A famous data is analyzed by the proposed procedure. For this example, the suggested method is straightforward for specifying distributionally and to implement computationally, with output readily adapted for required comparison.
