Seventeen compounds (1 - 17), ${\beta}$-sitosterone (1), lupenone (2), arborinone (3), ${\beta}$-sitosterol (4), lupeol (5), epi-lupeol (6), taraxerol (7), betulinic acid (8), 24R-methyllophenol (9), germanicol (10), hexatriacontane (11), nonacosan-1-ol (12), benzoic acid (13), tetradecyl(E)-ferulate (14), di(2-ethylhexyl) phthalate (15), trilinolein (16) and monopalmitin (17), were isolated from the methylene chloride-soluble fraction of the cork of Euonymus alatus Sieb. The structures of these compounds were elucidated on the basis of spectroscopic evidence. Compounds 6, 11, 13 and 14 were isolated for the first time from this plant. Compound 4 showed moderate cytotoxic activity with an $IC_{50}$ value of 6.22 ${\mu}M$ in HL-60 cell line. Compound 9 exhibited moderate cytotoxic activity with $IC_{50}$ values of 63.31, 15.45, 15.14 and 21.72 ${\mu}M$ in four kinds of human cancer cell lines, Jurkat T, HeLa, HL-60 and MCF-7, respectively. Compound 17 showed moderate cytotoxic activity with an $IC_{50}$ value of 70.71 ${\mu}M$ in Jurkat T cell line. In addition, compounds 2, 3, 14 and 16 exhibited weak antioxidant activity with $IC_{50}$ values of 151.76, 170.79, 137.46 and 139.37 ${\mu}M$, respectively.

Measurements of accelerometer levels transmitted from the floor in commercials truck shipments were carried out transportation of 300 Kg-load from Gyungbu Highway(Waegouan-Seoul) to 88 Highway(Gwangju-Daegu). Different characteristics were observed the values measured the vibration levels with directions in the two Highway's as a function of road condition and truck speed. The results showed that the vibration levels of the Gyungbu Highway is much higher than those of the 88 Highway. A following analysis on the obtained values was used to get the acceleration spectral density (ASD) and power spectral density (PSD). For the entire transit route, the results showed that the level of vibration to vertical direction was significant effects for damaging the products carried compared to other directions such as longitudinal and transverse. This paper provides an updated history of measured characteristics of vibration levels for highways using mainly in domestic area.

The purpose of this study is to provide an instrument of architectural programming in dwelling and facilities design for the mentally retarded. To do this the normal daily life activities have been analyzed and find the living characteristics who live in mental rehabilitation facilities. Generally, mentally retarded people have below IQ.75, and their normal daily life and social adjustment have some problem. Additionally, multiple disability existence and the difference of disability level have great difference in their living activities depend on person. For this research, People who live in 4 rehabilitation facilities in Daegu, Kyungbuk were investigated. It is particularly necessally space organization for sever retardation and multiple disability children, mild or moderate retardation children and adults to analyze their behavior of moving, stool, meal, and living in a group.

Purpose. The purpose of the study was to identify the mediating effects of nursing competency between transformational leadership and organizational commitment of nurses in hospitals. Method. Data were collected from 204 nurses in 3 hospitals and analyzed using descriptive statistics, Pearson' correlation coefficient, and hierarchial multiple regression with the PASW 21.0. Results. There were positive relationships among all three variables, transformational leadership, nursing competency and organizational commitment. There was a mediating effect of nursing competency between transformational leadership and organizational commitment. Conclusion. The results of the study indicate that strategies which could enhance the nursing competency of nurses should be developed by mangers in hospitals. Further study is needed on other factors which may influence nurses' nursing competency and organizational commitment especially in hospitals.

The purpose of this study was to examine the effect of consumption values on well-being attitude and the effect of well-being attitude on well-being oriented behavior. This study administered a questionnaire survey to adults between 10s and 60s who lived in Seoul, Daegu, and Kyungbuk region. Data collected from 285 respondents were analyzed by descriptive statistics, t-tests, ANOVA tests, factor analyses, and structural equation modeling (SEM). The model of the study was tested by structural equation modeling and the results of SEM revealed positive effects of social value and functional value on well-being attitude and positive effect of well-being attitude on well-being oriented behavior. The results of t-tests and ANOVA tests showed that there were significant differences in consumption values, well-being attitude, and well-being oriented behavior among marital status, age, educational level, and income level groups.

Multinomial logistic regression is probably the most popular representative of probabilistic discriminative classifiers for multiclass classification problems. In this paper, a kernel variant of multinomial logistic regression is proposed by combining a Newton's method with a bound optimization approach. This formulation allows us to apply highly efficient approximation methods that effectively overcomes conceptual and numerical problems of standard multiclass kernel classifiers. We also provide the approximate cross validation (ACV) method for choosing the hyperparameters which affect the performance of the proposed approach. Experimental results are then presented to indicate the performance of the proposed procedure.

The purposes or this study were to compare and analyze the differences between the elderly in their own home and those in facilities in terms of their self-esteem, death anxiety, depression level and psychological characteristics. The subjects were the 386 elderly over 55 living in home and in facilities, free or paid. They had no physical or cognitive disabilities and were living in Daegu city, Kyungbuk and Kyungnam province. There were significant differences in self-esteem, death anxiety, depression level and the path to depression between the two elderly groups with the elderly in facilities showing negative aspects of psychological characteristics. The problems of caregiving for the elderly should be covered by social welfare.

The purpose of this study was to examine the relationship between the attitude towards well-being and life satisfaction, to investigate the effect of healthy lifestyle and attitude towards well-being on life satisfaction, and to explore the differences in well-being lifestyle factors, well-being attitude, and life satisfaction against demographic variables. This study gave a questionnaire survey to adults between the ages of 10 and 60 who lived in the Seoul, Daegu and Kyungbuk regions of South Korea. Data collected from the 285 respondents was analyzed using descriptive statistics, correlation, t-tests, ANOVA, factor analyses, and regression analysis. The lifestyle for well-being was categorized into four areas, social welfare oriented activity, use of environmentally friendly products, self-esteem enhancement, and sports activity. Three of these factors were significantly correlated with the attitude towards wellbeing. The results of the regression analysis suggested that healthy lifestyle and attitude towards well-being affected people's life satisfaction.

Objectives: The main purpose of this study is to analyze the importance of the rotatory factor in PNF pattern. In this article has to analyze and clarify the importance of the rotatory factor in PNF pattern by comparing the general concepts, facilitation technics, and neuroscience of muscle spindle, etc. Methods: This is a literature study with books. Results : There is close relationships between the pattern in PNF and rotatory factor. PNF pattern is priorily made up the diagonal and spiral pattern. the rotatory factor influences and guides from the start to end in the pattern. Conclusions : Rotation component is most important of the three component that one flexion or extension, abduction or adduction and rotation. It is that provide longer muscle length and stimulate the muscle spindles.
