This study examined whether game usage would alleviate players' aggressive tendencies. Other game-related variables, psychological care factors (adaptive game use tendency, game self-efficacy, and life self-efficacy), and psychological problem factors (loneliness and depression) were controlled for determination of the effect. We drew on the catharsis theory from therapeutic psychology literature to explain how game usage contributes to the alleviation of aggressive tendencies. Over two weeks data were collected from 918 participants online. The results indicated that gaming activity had a significant effect on aggression. Higher levels of game and life self-efficacy, as well as adaptive game use tendencies, decreased the degree of aggression. Likewise, higher levels of loneliness and depression reduced the degree of aggression. Results and implications are discussed.

Draft is defined as an unwanted local cooling of the human body caused by air movement. It is a serious problem in many ventilated or air conditioned buildings. Often draft complaints occur although measured velocities in the occupied zone maybe lower than prescribed in existing standards. Purpose of this study is to clarify the evaluation of thermal comfort based on temperature and air velocity in winter. Experiments were performed in an environmental chamber in winter. Indoor temperature and air velocity was artificially controlled. The experiments were performed to evaluate temperature conditions and air velocity conditions by physiological and psychological responses of human. According to physiological responses and psychological responses, it was clear that the optimum air velocity is about 0.15 m/s and 0.30 m/s.

Self is well·expressed by clothing, so self-image can be an effective variable for conducting clothing·behavior studies. But there ate some problems in clothing and self-image researches. This paper will be a clue to discuss these problems. The contents of this study are as follows. (1) The notion of self-image is compared with self-concept, and according to this work, self concept comprehends the evaluative properties in addition to self-image illustration. In tai.; part, the problem in translating the terminologies, 'self-concept' and 'self-image', are also discussed. (2) The aspects of self-image are explored, thus physical and social-psychological aspects are determined. (3) Two sub-dimensions of self-image ate recommended relating to clothing researches: actual versus ideal and intrinsic versus phenomenal. (4) Some comments for future studies ate added. It is needed to investigate the relationships of other social- psychological variables and self-image in clothing department.

There are various methods of proving a proposition. Among these, 'mathematical induction' is treated in school mathematics weightly. But many students have difficulty with the proof by 'mathematical induction'. To solve this problem, analysis needs to be attempted in various aspects This study attempts to compare the teaching methods of 'mathematical induction' in South and North Korea and to acquire the implication. In fact, many differences between South and North Korea are found. These differences are caused by epistemological and psychological premise. Therefore this study investigates the epistemological and psychological aspects in North Korea and compares the textbooks in South and North Korea. Through this study, some implications are found. First, the sequence of introducing the 'mathematical Induction' needs to be considered. Second, the rich context of applying the 'mathematical induction' is needed. Finally, disagreement between curriculum and textbook in South Korea needs to be reconsidered.

The purpose of this study is to examine a theoretical framework for the interactions of learning in a small group setting of mathematical problem solving. Many researchers already have described the theoretical background for the small group settings in problem solving. However, most of the literatures merely have reported findings of achievement and rising of test scores. They ignored the observation of process taken during the small group work and have not determined how various psychological, social and academic effects are created. As results of the study, two types, mutual collaboration and asymmetric collaboration, of interactions are observed as the interactions of learning, which are conceived as the cores of authentic mathematical activities.

This study was conducted to examine the influence of the psychological health of the released offenders on their adaptation to community. Researchers analyzed the survey data of 216 participants who received joint marriage support from the Korea Legal Protection and Welfare Corporation. The results showed that the education level, marriage status, and monthly income were having a positive influence on the community adaptation of the released offenders, and the higher the depression and inter-personality among the risk factors of psychological health, the more negative the community adaptation. A higher sense of self-esteem, a psychological health protection factor, has a positive effect on community adaptation while reducing the influence of risk factors, depression and inter-personality. In sum, high self-esteem can contribute to increasing social life satisfaction after release from prison, promote risk factors to positive life changes, suppress negative situations and increase the possibility of successful community adaptation. Although this study confirmed that self-esteem is the most important factor among psychological factors for successful community adaptation of inmates, it will require relevant follow-up research and multi-disciplinary support because psychological factors alone cannot solve the problem.

Recently, as the domestic job problem has become serious, government ministries are investing a lot of budgets to encourage startups by prospective entrepreneurs. What is important to the success of startups is the recognition of various startup opportunities before starting a startup, and the experience through trial. However, in reality, prospective entrepreneurs recognize and seek various startup opportunities through support such as startup education and initial commercialization funds through various government supported projects, but it is difficult to actually start a business. Previous studies have revealed that the recognition of entrepreneurial opportunities affects entrepreneurial intentions by various variables such as gender, but research is insufficient on what kind of black box exists between the recognition of entrepreneurial opportunities and entrepreneurial intentions. The purpose of this study is to emphasize the importance of positive psychological capital as a major method for improving the entrepreneurial intention, and to analyze exploratorily whether positive psychological capital plays a mediating role between the recognition of entrepreneurial opportunities and the entrepreneurial intention. As a result of the study, it was confirmed that the recognition of startup opportunities affects the intention to start a business, and positive psychological capital has a mediating effect between the recognition of the startup opportunity and the intention to start a business. This means that positive psychological capital is important in order to lead to actual entrepreneurial intentions after recognizing a startup opportunity. Therefore, in order to revitalize the startups of prospective entrepreneurs in the current startup ecosystem, it is necessary to prepare a plan to improve the recognition of startup opportunities and positive psychological capital.

Purpose: This study aimed to investigate the effects of various factors on smartphone addiction according to types of risk groups among middle school students. Methods: Data of 223 students were collected from February 1st to 22nd of 2020. The collected data were analyzed through t-test, χ² test, correlaton coefficients, and multiple regression analysis. The smartphone addiction scale was used to classify the participants into two groups; 18.8% (n=42) of the total respondents were categorized as the addiction risk group and 81.2% (n=181) were categorized as the general population group. Results: The factors associated with the students in the high risk group were grade (t=3.89, p=.036) and religion (F=3.79, p=.044). In the high risk group, psychological anxiety (β=.39, p=.005) and relapse of internet addiction (β=.38, p=.006) explained 46.0% of smartphone addiction, while in the normal risk group, relapse of internet addiction (β=.42, p<.001), psychological anxiety (β=.22, p=.004), tolerance of internet addiction (β=.17, p=.007), and academic stress (β=.14, p=.027) explained 51.0% of smartphone addiction. Conclusion: In order to prevent smartphone addiction in middle school students, a more specific nursing intervention is needed that can reduce psychological anxiety and relapse of internet addiction. It is clear that urgent measures need to be taken for the highly addicted students such as academic counseling.

Background: Bell's palsy produces a complex problem that involves not only facial motor weakness, but also psychiatric issues. However, the relationship between facial neuromotor system impairment and psychological adjustment has not been well understood. Methods: We have performed psychological evaluations in patients with acute unilateral Bell's palsy within 2 weeks after onset. Thirty patients with Bell's palsy (10 men, 20 women) were included, who were diagnosed by neurologic examination, electrophysiologic study and/or brain MRI. We measured facial motor scale of impairment (House-Brackmann, HB scale) and psychosocial adjustment [Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI)] at the time of initial presentation and 1 month after diagnosis. Results: The age of the enrolled patients ranged from 16 to 80 years. The mean grade of initial and follow up HB scale were 3.87 (SD: 0.63, range 2~5) and 1.77 (SD: 1.10, range 1~5). The mean score of initial and follow up BAI, BDI were 11.93 (range; 0 to 47, SD: 9.65, very low anxiety), 14.73 (range; 0 to 41, SD: 9.21 minimal depression) and 7.5 (range; 0 to 36, SD: 8.58, very low anxiety), 9.33 (range; 0 to 30, SD: 8.19 minimal depression). There was positive correlation between improvement of HB scale and improvement of BAI and BDI score. Conclusions: Bell's palsy is associated with the psychological problems such as depression and anxiety, and the improvement of motor symptom is associated with the improvement of these psychological problems.
