This paper introduces a method for extracting subtitles from lecture videos through a Korean morpheme analyzer and classifying video categories according to the extracted morpheme information. In some cases incorrect information is entered due to human error and reflected in the characteristics of the items, affecting the accuracy of the recommendation system. To prevent this, we generate a keyword table for each category using morpheme information extracted from pre-classified videos, and compare the similarity of morpheme in each category keyword table to classify categories of Lecture videos using the most similar keyword table. These human intervention reduction systems directly classify videos and aim to increase the accuracy of the system.

This study aims to analyze the impact of names on stress and self-esteem, comparing before and after renaming. A survey was published and conducted on a renaming club website for the period from 1 April 2013 to 31 May and there were 161 participants. The invitation to survey was limited to members who had changed their names at least six months before the survey and the impact was measured by comparing before and after the first renaming. For the analysis of the data, frequency analysis, t-test, one-way ANOVA and correlation analysis were performed. As a result, the level of stress caused by one's name was lowered after renaming, and one's self-esteem significantly went up compared to before renaming. Therefore, the stress from one's name is believed to affect one's self-esteem, and the study shows that there is a negative correlation as the lower the stress from one's name becomes, the higher one's self-esteem goes up. Therefore, this study is considered to be able to contribute to reducing stress caused by names, as it has proved that the self-esteem increases and the level of stress is lowered after renaming.

Present study investigated the effects of poverty and poverty-co-factors in childhood. The effect of poverty status was measured by needs-income ratio. It compared its effect on children's socio-emotional development with that of poverty proxy variables such as recipient of public assistance, financial stress, subjective perception about social class, residence in public housing. It also examined the effects of poverty-co-factors after poverty status were controlled. Results show that poverty status has a more consistent negative relationship with socio-emotional development than other proxy variables. However, the relationship between them disappeared after poverty-co-factors were controlled. Findings from the present study suggest that targeted efforts for decreasing poverty-co-factor risks should be made along with financial support.

This study is about a strategy to analyze learning activities in an intelligent learning system. To this end, the conceptual definition of the intelligent learning system and the type of learning using the intelligent learning system were analyzed. The learning types were presented as individual, adaptive, competency-based, and blended learning, and although there are some differences, most of them have similar characteristics. In addition, learning activity analysis is based on data such as mouse clicks, keyboarding, and uploads generated by the system. Through this, basic analysis such as viewing time and number of uploads can be performed. However, more diverse learning analysis is needed for personalization and adaptation. It can judge not only learning attitude and achievement level, but also metacognitive level and creativity level. However, since the level of metacognition includes complex human cognitive activities, the teacher's intervention is required in the judgment of the intelligent learning system.

This study aimed at understanding the experience in deciding for childcare of unmarried lone mother and searching for intervention methods through in-depth examination of the essence of the experience. To achieve this, the Colazzi analysis of phenomenological research was applied. The subjects of study were 7 unmarried lone mothers in early age of the twenties and thirties, who resided in an institution for unmarried lone mothers. An in-depth interview was held individually with them with question of "What is the experience in deciding for childcare as a unmarried lone mother" twice on the average from Nov. 2003 to Feb. 2005. The results found that a unmarried lone mothers' experience in childcare meant 'resurrection' through analyzing 22 themes and 7 theme clusters(confusion due to pregnancy, harsh feeling for reality suffering alone, feeling of love for a baby, mental conflict about childcare, decision toward childcare, firm in decision, hope for resurrection). Although the results of this study have the limitation of generalization due to phenomenological study, it will contribute to accepting and understanding mother-and-child families as one type of family rather than regarding them as being difficult or alienated in family and society, to recognizing the need of taking back their rights, and to suggesting intervention methods for unmarried lone mothers.

The purpose of this study is to verify the feasibility of a model, based on the Theory of Planned Behavior (TPB), that predicts the intention of a problem gambler to abstain from gambling. In order to investigate attitudes toward gambling abstinence, subjective norms, perceived behavior control, and intentions to abstain from gambling, we surveyed 100 problem gamblers who used community-based service centers. Furthermore, we analyzed by the structural equation model whether attitude toward gambling abstinence, subjective norms, and perceived behavior control can influence the intention to abstain from gambling. The analysis of the study model revealed that the most powerful predictor of the gambling abstinence intention is perceived behavior control, followed by a positive attitude toward gambling abstinence. In contrast, subjective norms did not show a significant influence on intentions for gambling abstinence. Based on these results, we propose cognitive-behavioral interventions to improve attitudes and self-efficacy toward gambling abstinence in order to help problem gamblers recover. In other words, continuous support and coping-skills training are needed to reinforce the belief that people can recover from a gambling problem, and information and education on problem gambling to improve positive attitudes can also be helpful. Therefore, it is possible to consider not only the treatment of gambling problems, but also to provide preventive interventions centering on the addiction management institution.

The purpose of this study was to develop the Post-bereavement Growth Inventory(PBGI) for the elderly and to evaluate its validity. The items for developing PBGI were compiled from a literature search, content validity review, and a preliminary survey. A main survey of 308 widowed persons(aged 60+) was conducted. The results were as follows. First, an exploratory factor analysis revealed six factors of the PBGI. The results of the confirmatory factor analysis supported a five-factor structure for the final 24 scale items of scale. Second, in terms of concurrent validity, the PGBI compared favorably with the "Personal Growth" scale from The Hogan Grief Reaction Checklist (HGRC: Hogan and Schimdt, 2001). Third, the results of contrast group validity tests demonstrated that the group scoring in the upper 30% on the scales of Psychological Well-being (PWB, Ryff and Keyes, 1995) and the Grief Reaction Inventory (GRI: Remondet and Hansson, 1987) showed a significantly higher degree of post-bereavement growth (PBG) than the group scoring in the lower 30%. Fourth, Cronbach's ${\alpha}$ values for the five factors were between .649-.856 and .907 overall, indicating high internal consistency. Finally, education had the most significant influence on PBG. All results indicated the high validity of the PBGI. The findings from this study could provide the rationale for practical interventions from a growth-oriented perspective for widowed persons, as well as an objective assessment tool for practitioners in clinical areas.
