The purpose of this research is to study the middle and high school student’s value on the family life of the contemporary society. The data for this study has been collected for 808 students of kangwon-do by Liert-scale Type questionnaire. The data were processed by SPSS-X Program. Frequency, Percentage, Mean, Standard Deviation, One-way ANOVA, Pearson’r coefficient, Step-wise multiple regression and Cronbach’coefficient have been calculated and analyzed. The Summary of this research is described as follows. Firstly, the overall average of value of family life was 3.25 points which reflected more or less modern tendency. Secondly, significant difference in the student’s value of family life affected by environmental variables were such as sex(P<.001) school years(P<.001) group(P<.01). Thirdly, the overall average of the student’s interest in the home economics was 3.74 points which reflected heigher tendency, Significant difference in the student’s interest in the home economics according to environmental variables were such as sex(P<.001) school years(P<.05), living standard(P<.01), residential area(P<.001). Fourthly, the student’s overall interest in the home economics and their view on the family life were correlated as follows; Spare time(r=-1.3), parents-children(r=.12) relatives and neighbors(r=0.8) show lower correlation and household work(r=.07) show higher correlation. Fifthly, the area which has closest correlation with the value on the family life was the value on family economics, whereas is has been shown that the field with least correlation was the area of supporting the spare time. Sixthly changes that affect the student’s value of the family life were such as sex (${\beta}$=.43), school years(${\beta}$=.18), group(${\beta}$=.15) and interest degrees(${\beta}$=-.12). These whole explanatory power was 21%.

The purpose of this study was to investigate an association between anxiety, cellular phone addiction and adjustment to college life in undergraduate students using structural equating model (SEM). This study was verify whether adjustment to college life mediated the relationship between anxiety and cellular phone addiction. Participants of this study were 479 undergraduate students in Gwangju city in accordance to convenience sampling. SPSS 15.0 was employed for descriptive statistics, Pearson correlation coefficient, calculation for cronbach's ${\alpha}$ coefficient, exploratory factor analysis. Also, AMOS 7.0 was employed for confirmative factor analysis and path analysis of casual relation among variables and effect. The results of this study can be summarized as follows. First, anxiety had a negative effect on adjustment to college life and adjustment to college life had a negative effect on cellular phone addiction. Second, anxiety had a positive effect on cellular phone addiction. Third, it was founded that adjustment to college life partially mediated the relationship between anxiety and cellular phone addiction.

This study was conducted to confirm the mediating effect of self-esteem and social support in the relationship between life stress and depression in middle-aged men. Data analysis was performed using the SPSS/WIN 25.0 program, t-test, ANOVA, pearson's correlation coefficient, SPSS Process Macro (Model 4), and bootstrapping approach. As a result of this study, when considering the effect of self-esteem, a parameter in the relationship between life stress and depression, the direct effect of life stress on depression was .49. Considering the effect of social support as a parameter, the direct effect of life stress on depression was .50. That is, when the parameters were not considered, life stress decreased compared to the overall effect of .62 on depression. Through this, it was confirmed that self-esteem and social support had a mediating effect in the relationship between life stress and depression.

The purpose of this study was to clarify tile tendency of differences in housing values and life style of high school students in Chonbuk province. Data were collected through questionnaires from 1015 high school students living in Chonbuk province, and were analyzed by SPSS program using percentage, mean and standard deviation. Data were verified by t-test, One-way Anova, Scheffe's multiple range test, Pearson's correlation coefficient as well. The findings of this study were as follows; There were more significant differences in housing values and life style by demographic variables than housing characteristic variables. And correlation between housing values and life style differed significantly Most of students showed higher value in location of housing, while as life style showed higher value in type of life style along with PC. On the basis of this result,. it can be suggested that it is necessary to have the right understanding about housing values and life style of high school students for correct guidance of housing education.

The purpose of this study was to clarify the relationship between life style and housing satisfaction of high school students. This is the investigation of which 1015 high school students live in Chonbuk province. In this statistical analysis, SPSS program was utilized to calculate percentage, mean and standard deviation. Also. these materials were verified by t-test, one-way ANOVA, Pearson's correlation coefficient. The main results of this study were as follows. There was a significant difference between life style and housing satisfaction, according to demographic variables and housing characteristic variables. The entire life style has been appeared high type of a along with PC. Most of students has been appeared high in health and security of housing. Also, correlation of life style and housing satisfaction showed significantly. On the basic of these results, it can be suggested : It is necessary to have the righteous understanding about life style and housing satisfaction, of high school students for advisable guidance of housing education. It needed to continue diversified researches considering spread of life style 'with PC' and enough awareness of health and security in housing satisfaction.

In the recent day, fatigue life prediction techniques play a major role in the design of components in the ground vehicle industry. Full scale durability testing in the laboratory is an essential of any fatigue life evaluation of components or structure of the automotive vehicle. Component testing is particulary important in today's highly competitive industries where the design to reduce weight and production costs must be balanced with the necessity to avoid expensive service failure. Generally, 3-axis durability testing device is used to carry out the fatigue test. In this paper, The operation software for simultaneously driving 3-axis vibration testing device is developed and the displacement of the 3-axis actuator is separately calibrated by LDT Moreover, the input and output data are displayed in windows of PC controller with real time.

This study was done to develop an euthanasia attitude scale. Subjects who participated in the study were a convenience sample of 234 Korean nurses. Data were collected through a survey over a period of three months. The analysis of the data was done using SPSS PC for descriptive statistics, factor analysis and Cronbach's Coefficient Alpha. Initially 63 items were generated from interview data from eighteen nurses and from a literature review. This preliminary scale was analyzed for a reliability and validity. The results are as follow: 1, Crombach's Coefficient alpha for the 19 items was .8804. 2. Factor analysis was done in order to confirm construct validity and four factor were extracted from the results. These contributed 56.6% of the variance in the total score. 3. Each factor was labled 'qualify of life', 'respect of life, 'client's right', 'medical ethics'. The author suggests that this scale could be used in assessing the attitude of Korean nurses toward euthanasia.

The present work presents analysis results of the core design optimizations for an annular, prismatic High Temperature Gas-cooled Reactor (HTGR) with passive decay-heat removal features. Its thermal power is 100 MW_t and the operating temperature is 850 ℃ (1123 K). The neutronic calculations are done for the core with heterogeneous distribution of fuel and burnable poison particles (BPPs) to flatten the reactivity swing and power peaking factor (PPF) during the reactor operation as well as for control rod (CR) insertion into the core to restrain a small excess reactivity less than 1$. The next step of the study is done for evaluation of core reactivity coefficient of temperature.
