Background & Objectives: Recently, problems such as in-school violence of teenagers, gang fight, habitual drinking, smoking, running away from home and group isolation can be regarded as the most fundamental causes of teenagers' deviation. It is said that such fundamental causes are originated from their home, the base for the psychological and behavioral development. Methods: In this study, the data for 3,188 students studying in the 3rd grade at middle school, which have been obtained from the second year survey for the panel of the 2nd grade students in 2004 by to Korea Youth Panel Survey, have been used for the analysis of the study. Results: According to the result of the study, there seems to be no difference between two genders for differences of average values. Regarding the analysis of correlation coefficients between such related variables as domestic violence, self-control, self-worth, self-trust and family relationship (sociability), and teenagers' deviation, When variables increase, teenagers' deviation decreases. Regarding the relationship between domestic violence and teenagers' deviation, physical violence is more related than lingual violence. The relationship between self-control and teenagers' deviation is the highest. By studying the deviation of teenagers exposed to domestic violence and carrying out the regression analysis, physical violence influences, teenagers' deviation was greater. As self-control, self-worth and family relationship(sociability) increase, teenagers' deviation decreases. Regarding the analytic results of this study, the experience of domestic violence seems to influence teenagers' deviation greatly. Among various types of domestic violence, physical violence is analyzed to influence teenagers' deviation greatly. Self-control, self-worth and family relationship(sociability) increase, teenagers' deviation decreases. Conclusions: In order to prevent teenagers' deviation and decrease the second conviction rate, it is necessary to provide a method of decreasing the domestic violence. It is necessary for schools and local communities to provide social support for teenagers.

In the international businesses human resource elements acquired in different countries might have different values in varied industries due to the different quality of education and experiences in the original countries. Using selection models to evaluate expected values in earnings equation of human resource elements such as education and experiences etc. acquired in sending countries, system equations are expanded to examine also the values of science and engineering degrees in technology jobs with selectivity bias correction. This paper used the US census survey data of 2015 on earnings, academic degrees, occupations etc. The US has long maintained the policy of accepting more STEM workers than any other countries and helped maintaining own technological leadership. Assuming per capita GDP gap between the sending country and the US downgrades immigrant human resource quality, it rarely affects occupational selection but depresses earnings on average by two or more years' worth of education. Immigrant quality index in the sense of GDP gap appears to be a valid tool to assess the expected earnings of the worker with. Engineering degrees increase significantly the probability of selecting not only engineering jobs but also general management jobs, as well as increasing the expected earning additionally over nine years'worth of education. Getting a technology job is additionally worth about four years of education. Economics and business degrees are worth additionally almost six years of education but humanities degrees depress expected earnings. Since years after immigration does not very fast enhance earnings capacity, education level and English language ability might be more useful criteria to expect better future earnings by.

This study analyzed private pension dependency of Korea and U.S. households using the most recent dataset of two countries. For this purpose, 2013 Korean Retirement and Income Study(KReIS) of national pension research institute in Korea and 2013 SCF(Survey of Consumer Finances) of FRB in U.S. were used. The private pension dependency was defined as the proportion of private pension wealth among total financial wealth in each household and tobit model was used to investigate determinants of private pension dependency of the two countries. After controlling for other factors, household income and net worth, age, educational attainment, and health status of householder were crucial determinants of private pension dependency for both countries. Householder's age, educational attainment, and health tend to increase the private pension dependency in Korea and U.S. However, household income and net worth affected the private pension dependency opposite direction. The private pension dependency increased with high level of income and net worth in Korea, while it decreased with high level of income and net worth in U.S. Results of this study provide useful implications for future pension system and policy in Korea.

In this paper, three-dimensional neutronic calculations were performed in order to calculate the dependency of CRW on the temperature of fuel and moderator and the moderator void. Calculations were performed using the known MTR_PC computer codes in the core configuration 61 of TRR. The dependency of CRW on the fuel temperature in the range of $20-340^{\circ}C$ and the moderator temperature of each control rods were studied. Based on the positions of the control rods, the calculations were performed in three different cases, named case A, B and C. By the results, the worth of each control rods increases by increasing of the coolant temperature in all methods, however, the total CRW is somewhat independent of the fuel temperature. In addition, the results showed that the variation of CRW versus density depends on the positions of the control rods and the most change in CRW in the coolant temperature, $20-100^{\circ}C$ (279 pcm), belongs to SR4. Finally the effect of void on CRW was studied for different void fraction in coolant. The most worth change is about $2 for 40% void fraction related to SR1 and SR3 in case B. For 40% void fraction, the total CRW increases about $7.5, $6 and $7 in cases, A, B and C, respectively.

The purpose of this study is to confirm the productivity of housework empirically by analyzing the newspaper articles during the financial aid from the IMF. During this period, Korean Households expenses. And Korea government also wanted to share the burden of overcoming the currency crisis with households. Theoretically, Home economists has approved the productivity of housework as it increases the worth of wage by reducing cost of labor reproduction. So this article try to verify the productivity of housework by analyzing if there was public demand of housework as a means of reducing expenses during the IMF regime, based on newspaper articles. The major findings that are derived from the study are as follows : First, during the IMF regime, Households and housewives were described as an agent of overcoming economic crisis in newspaper articles. Second, households were required to substitute money expenses for housework to cut expenses. These results show that housework has worth as a productive labor and contribute to society and households as it increases the worth of wage and deceases the cost of living.

The purpose of this study is to examine, according to sex and grade, the relationship and difference between mothers' parenting attitudes and self-perceived competences of their children. 197 children of the 4th through the 6th grade were selected from an elementary school in Daejeon area. We used the Perceived Competence Scale for Children (Harter, 1982) to measure their self-perceived competence and the Mother's Parenting Attitudes Scale (1990, Lee & Park) to measure parenting attitudes of their mothers. Major findings are as follows: First, there were significant differences in the children's self-perceived competence according to their perception of parental warmth and control. Children with more perception of parental warmth and consistent control considered themselves higher in cognitive and social competences and in self-worth. Boys perceived higher mother's consistent control and positive participation in parenting-attitudes than girls. Girls perceived themselves higher than boys in global self-worth. Next, Out of the three grades the 4th graders indicated more perception of attachment, authoritarian control, and positive participation in parenting attitudes. There was statistically no difference in self-perceived competences of children according to their grades. Finally, there were correlations between mothers' parenting attitudes and perceived competences of their children. Children with more perception of parental warmth, attachment, positive participation, and consistent control showed higher level of physical competence, social competence, and global self-worth.

Recently, a CANDU digital reactivity computer system (CDRCS) to measure the worth of the liquid zone controller in a CANDU-6 was developed and successfully applied to a physics test of refurbished Wolsong Unit 1. In advance of using the CDRCS, its measureable reactivity range should be investigated and confirmed. There are two reasons for this investigation. First, the CANDU-6 has a larger reactor and smaller excore detectors than a general PWR and consequently the measured reactivity is likely to reflect the peripheral power variation only, not the whole core. The second reason is photo neutrons generated from the interaction of the moderator and gamma-rays, which are never considered in a PWR. To evaluate the limitations of the CDRCS, several tens of three-dimensional steady and transient simulations were performed. The simulated detector signals were used to obtain the dynamic reactivity. The difference between the dynamic reactivity and the static worth increases in line with the water level changes. The maximum allowable reactivity was determined to be 1.4 mk in the case of CANDU-6 by confining the difference to less than 1%.
