The purpose of this study is to understand the experiences of adults after leaving the care of the institution. To accomplish this purpose, we have collected various data from participants who left child care institution more than five years ago and analysed these data through qualitative data analysis method. The results showed that three key themes namely, "isolation-helplessness", "being chained to their past", and "marching towards a better future". "Isolation-helplessness" is divided into "becoming a real orphan" and "fighting alone the unsupported". "Being chained to their past" are composed of "institution, a hometown that one needs to leave", "being marked as a institutionalized person" and "scars and marks". Lastly, "marching towards a better future" are grouped into "taking advantage of institutional experience", "helping each other", "drawing a fine picture of their future happiness" and "moving ahead sweeping aside all difficulties". Lastly, this study suggested political and practical measures to enhance wellbeing of adults that have left the institutional care.

We attempted to confirm the current status of the use of mobile phones by soldiers, especially SNS, in today's situation where the use of mobile phones is completely allowed, and to reach an agreement for the use of functional SNS in military life. To this end, 189 students at the Korea Army Academy at Yeongcheon were measured for SNS use motivation and life satisfaction, and the relationship between each sub-variable of SNS use motivation and satisfaction was analyzed. As a result, 3 out of 4 motives for using SNS had nothing to do with satisfaction, and rather, among the sub-variables, the pursuit of status showed a negative correlation with satisfaction. Therefore, the use of SNS to search for information or ideas should be encouraged. In addition, these findings prove that the vague belief that allowing SNS will increase the satisfaction of soldiers is not reasonable, suggesting that a careful approach is required to utilize functional SNS in the military.

This study employs Lacan's psychoanalytic approach to reinterpret the images of others and teachers that influence the process of self-formation within the teaching profession as students enter a university of education Seventy-four first- and second-year students majoring in science education at the College of Education from three regions across the country participated in this study, which was conducted using Lacan's L schematic as a representative theoretical framework. Through qualitative analysis and a word cloud analysis, it was confirmed that the students developed perceptions of the teaching profession based on somewhat fictitious and unrealistic teacher images, while others actively intervened in the process of career decision-making. In addition, although parents or teachers mainly occupied the realm of the Other, it was found that they failed to appropriately fulfill the role of the Other, in that they should have corrected the fictional image of teachers. Accordingly, it is necessary to recognize the limitations of ego-psychological career education that can deepen fixations on distorted self-images and, therefore, seek a new career education and counseling model through a psychoanalytic approach.

Recently, the emergence of a variety of devices to be able to access web have brought many technological changes in the field of web development. However some web sites are still operating with a focus on computers, especially exclusive and slow developing job training related web sites which utilize a User Interface that targets only PCs. In this paper, we propose the job training management system which has a menu configuration and functions to be applied to a variety of devices, and also an applicable technologies for training students to access more easily. Finally, we evaluated its efficiency by applying the implemented system in the actual field.

In order to determine the protein requirements of the Korean rockfish Sebastes schlegeli six isocaloric diets containing crude protein level from 20\%\;to\;60\%$ were fed to two groups of fish, small and large size, with the initial average body weight of 8 g and 220 g respectively. White fish meal was used as a sole protein source. Daily weight gain, daily protein retention. daily energy retention, feed efficiency, protein retention efficiency and energy retention efficiency were significantly affected by the dietary protein content (p< 0.05). The growth parameters (that is, daily weight gain, daily protein retention and daily energy retention) increased up to $44\%$ protein level with no additional response above this point. The protein requirements were determined from daily weight gain using two different mathematical models. Second order polynomial regression analysis showed that maximum daily weight gain occurred at $56.7\%\;and\;50.6\%$ protein levels for the small size group and the large size group, respectively. However the protein requirements, determined by the broken line model, appeared to be about $40\%$ for both groups. Nutrient utilization also suggested that the protein requirements of both groups were close to $40\%$. When daily protein intake was considered, daily protein requirements per 100g of fish, estimated by the broken line model, were 0.99g and 0.35g for the small and large size groups respectively. Based on these results, a $40\%$ dietary crude protein level could be recommended for the optimum growth and efficient nutrient utilization of the Korean rockfish weighing between 8g and 300g.

This study is a research based on an existing analysis that peak values of unit hydrograph are variant according to rainfall intensity in a watershed. Differently from the fundamental assumption that an unit hydrograph is time-invariant in a watershed a variant unit hydrograph to rainfall intensity by storms is defined and applied into rainfall events, which produces out runoff hydrograph for an examination. Peak flow and time to peak of unit hydrograph used for an application are obtained from the relation equation with rainfall intensity developed by a previous study reviewed, and its shape is made by Nash unit hydrograph which is determined by the peak values. For the purpose of a comparison an invariant unit hydrograph is defined as Nash model obtained from averaged peak values of unit hydrograph which is derived by 26 rainfall storms. Peak flow and time to peak of flood hydrograph developed respectively by variant unit hydrograph with rainfall intensity and an averaged unit hydrograph are compared to those of the observed hydrograph. With comparing both hydrographs calculated by averaged unit hydrograph and revised unit hydrograph to observed hydrograph it is shown the peak flow and time to peak of hydrograph calculated by time-invariant unit hydrograph revised in this study are closer to those of observed hydrograph than those calculated by averaged unit hydrograph.

This study was to examine whether musically talented adolescents' passion and achievement goals influence their deliberate practice. Of the musically talented adolescents surveyed from two arts high schools in Seoul, Korea, 597 completed and returned the questionnaires. Their average age was 17.4 years. Paired t-test on musically talented adolescents' passion(i.e., harmonious passion, and obsessive passion) and achievement goals(i.e., mastery goals, performance-approach goals, and performance-avoidance goals) indicated that harmonious passion were higher than obsessive passion. Mastery goals were higher than performance-approach goals. And performance-approach goals were higher than performance-avoidance goals. Independent t-tests were measured between high and low deliberate practice(DP) groups. High DP group showed higher harmonious and obsessive passion, and mastery and performance goals than low DP group. It was also found that two types of passion(i.e., harmonious and obsessive) positively influenced on deliberate practice via mastery goals.

The purpose of this study is to compare the differences in aboveground flora and underground flora between a forest road and a forest edge and to clarify each characteristic through ecological approach to a forest road. The study site was the forest planted with Pinus koraiensis and Abies holophylla, and located at an altitude of 45m($36^{\circ}36'23''N127^{\circ}21'45''E$). The width of the forest road is 3.2m. This research set the forest edge within the areas 5m away from the forest road and also conducted a survey on vegetation 5 times from september 2006 to August 2007. In addition, it installed thirty six quadrats to make an analysis of reclaimed soil seed bank. Soil amounting to 600$cm^3$ was collected from each quadrat using soil samplers(100$cm^3$),which was preserved in low temperature refrigeration for a month. Soil was thinly strewed evenly on trays and watered every four or five days; then, this research did experiment for six months until no more germination took place. Through this process, this research identified species and counted the number of germinating individuals by using emerging seedlings. The research result showed that on the whole, the similarity index between aboveground flora and underground flora was low. The correlation coefficient between the aboveground flora vegetations both on the forest road and on its edge was found to be 0.36, showing a correlation with each other(p<0.05). On the other hand, the correlation coefficient between underground flora vegetations through the analysis of reclaimed soil seed bank was 0.20, showing no correlation with each other(p>0.05). As the survey result of naturalized plants, there existed 7 species of naturalized plants on the forest road in case woody plants were included, showing 11.11% naturalization rate and 2.61% urbanization index(UI). On the other hand in case woody plants were not included among the naturalized plants, the naturalization rate on the forest road was 12.50% while the naturalization rate on the edge of the forest was 9.09%.
