Spiritual direction is not a product created and developed by an individual, but a historical product that includes the church, believers, society, and the contexts of the times. Among the social changes related to spiritual direction, this study pays attention to monasticism and the Reformation. Focusing on these two social changes, this study analyzes the social dimension of spiritual direction indicated by the occurrence and change of spiritual direction and discusses its meaning. Around the time Christianity was officially recognized by the Roman Empire, monasticism began its long history, and Athanasius spread his ideal of monastic life and at the same time pursued the unity of the church and the monastic movement. Through this process, spiritual disciplines and educational models interacted and changed. During the Reformation period, Protestantism began to form new spiritual education and training. The Catholic Church pursued renewal through new concepts and practices of spiritual direction. Spiritual direction is being formed and recognized as a means of helping the spiritual life of individual Christians. The origin and change of spiritual direction mean that spiritual direction can be understood and applied differently reflecting the contexts and situations due to social interaction. Also, it should not be overlooked that spiritual direction can act as a cause of integration or division of the Korean Protestant churches.

The purpose of this study was to provide a foundation for the methods of stretching in sports activities. The subjects were normal adults, the applied exercise was dynamic and static stretching and the research methods were measuring the jump height and muscle activity during jumping with subsequent data comparison and analysis. Twenty normal adults were randomly divided into 2 groups, and each group performed dynamic or static stretching. Jump height and the vastus lateralis and gastrocnemius muscle activities were measured during jumping, which was performed immediately before and after stretching. Statistical analysis was performed using an analysis of covariance. The results indicated that dynamic stretching was more effective than static stretching with respect to both jump height (p<.05) and muscle activity of the vastus lateralis (p<.05). Consequently, it was believed that dynamic stretching should be applied as a warm-up exercise for athletes who need to build and maintain high muscle strength.

This study was designed to examine the effects of weight reduction programme(WRP) for obese primary school students on serum lipid level. This research used non-equivalent control group non-synchronized design that was conducted on two groups comprising 5th and 6th graders: an experimental group that received 12-week long WRP that combines diet, exercise and behavior modification therapy and the control group that did only rope-jumping. The collected data were analysed using ${\chi}^2$-test, t-test, ANOVA, Pairwise Comparsons by SPSS 18.0 Programme. It was proven that the WRP of this study was effective in lowering the total cholesterol(F=4.21, p=.049) and triglyceride(F=4.25, p=.049). WRP may be used as a basis for further studies that may be conducted after intervening the motivation level of the study subjects.

The purpose of this study were a two-fold: (1) to analyze event and phase of handspring salto forward stretched with turn; (2) to know the differences in the kinematic variables between two groups. A Kwon3D program served for the estimation of this study. The group was divided into three National representative and three well-trained calisthenics in this study. The results of this study revealed that (1) the forward somersault performance was increased when duration time in the air was long during the salto forward stretched that the duration time of Handspring is short, the pressure at takeoff is high, the stride is large, and hands are supporting on the ground quickly; (2) comparing the angular movement of anterior and posterior y axis and vertical z axis, the angular movement of right and left $\times$ axis was higher during the performance. As a result, the national representative players showed better performance in Handspring salto forward stretched with turn.

The authors examined the patterns and various ranges of mandibular movements in TMJ lock closed patients in the frontal, sagittal and horizontal plane pre-end post-treatment. And the author obtained the following results. 1. In the frontal plane, the patterns and ranges of mandibular movement of the patients were very irregular and small before treatment. But after the treatment, the patterns were similar to the typical shield shape of the normal subjects. And the velocity of opening and closing was improved after the treatment. 2. In the sagittal plane, the mean amount of maximum mouth opening was 27.0±4.0mm before treatment and 44.0±5.4mm after treatment. And there was statistically significant improvement(p<0.005). The patterns of the movement were very irregular and small before treatment, but were similar to the shape of "Posselt's envelope of motion" after the treatment. The velocity of opening and closing was improved after the treatment 3. In the horizontal plane, the mean amount of maximum laterotrusion was 8l2±2.5mm in the affected side and 6.7±2.2mm in the non-affected side before treatment. There was a significant difference between the sides(p<0.05). After the treatment, the mean was 10.4±2.6mm in the affected side and 8.9±2.3mm in the non-affected side and there was no significant difference between the sides(p>0.05). There was no significant difference in the mean amount of maximum protrusion between the before and aftertreatment(p>0.05), but the patterns of the movements were improved.

The activity of an antimicrobial peptide, protegrin-1, on the well-aligned lipid bilayer deposited on a thin coverglass plate was investigated by $^2H$ solid-state NMR spectroscopy. Orientational distribution and molecular motion in the lipid bilayer were determined from $^2H$ solid-state NMR spectrum. Reorientational motion of lipid molecules in the vacuum-dried state was found to be small but their orientational distribution was not able to be determined. As storage times were longer, the order of the alignment of lipid molecules in the lipid bilayer and percentages involved in the toroidal pore structures increased. We found that much longer time is required to get the equilibrium state of the peptide-lipid mixture under our experimental condition for investigating the action of the antimicrobial peptide like protegrin-1 on the lipid bilayers deposited on the thin coverglass plates.
