The development of IT technology that has come to symbolize the fourth industrial revolution, the introduction of online government, and the change in environment has caused radical changes in record management. Most public institutions under the government make use of information systems that are objects of information protection such as electronic document system, document management system, and Onnara system. Further, protection and access control of record information through physical environment and electronic system in a user-centered record management environment is an essential component. Hence, this study studies how professional records management professionals in public institutions recognize safe protection and access management of record information, deriving areas that require improvement and providing a discussion and suggestions to bring about such improvement. This study starts by examining laws and policies on information protection in Korea, analyzing items on access control to compare them with laws and policies, as well as the current situation on records management and derive implications. This study is meaningful in that it aims to substantialize records management by suggesting areas of improvement necessary for the protection and management of record information in public institutions and providing professionals with tangible authority and control.

This study examined the effects of song-based group music therapy on the exercise stress and positive psychological capital of youth soccer players. Eighty youth soccer players were assigned to either a song-based music therapy group or a control group. For the analysis of the effects of song-based group music therapy, the Exercise Stress scale and the Athlete Positive Psychological Capital scale were administered before and after the intervention. The collected data were analyzed using an independent sample t test and paired t test. The results were as follows. First, the experimental group showed a significantly lower posttest score on the exercise stress measure than the control group (p < .01). The control group showed a significant increase from pretest to posttest on the exercise stress measure (p < .05). Second, the experimental group scored significantly higher at posttest than the control group on the positive psychological capital measure (p < .01). The control group demonstrated a statistically significant decrease from pretest to posttest on the positive psychological capital scale (p < .05). The results suggest that song-based group music therapy is an effective treatment method that lowers exercise stress and raises positive psychological capital of youth soccer players.

The purpose of this study is to compare junior high school students' conceptual changes about force and motion and their interest in science between a group with the instruction including sports experiential learning activities and a group with traditional instruction. In addition, for a group with sports experiential learning activities, students' conceptual changes and interest were examined according to the degree of their sports-experience before the instruction.The subject was 7th-grade students(N=82), and they were divided into two groups: experimental group and control group. The conceptual changes were positive in both groups. In the multiple choice questions the experimental group students(20.0%) were more positively changed than the control group students(17.2%). The number of students who responded with the right explanation increased 26.7% in the experimental group and 10.4% in the control group. The interest of the control group was significantly increased in the topic dimension(p<0.05). The interest of the experimental group was significantly increased in the experiential activity and the communicative activity(p<0.05). Students who had much sports-experience showed the most positive changes. Moreover the interest of these students was especially increased in internal motive, receptive activity, experiential activity, and communicative activity.

Individuals with problematic hypersexual behavior (PHB) evince the inability to control sexual impulses and arousal. Previous studies have identified that these characteristics are related to structural and functional changes in the brain region responsible for inhibitory functions. However, very little research has been conducted on the functional connectivity of these brain areas during the resting state in individuals with PHB. Therefore, this study used functional magnetic resonance imaging devices with the intention of identifying the deficit of the functional connectivity in the executive control network in individuals with PHB during the resting state. Magnetic resonance imaging data were obtained for 16 individuals with PHB and 19 normal controls with similar demographic characteristics. The areas related to the executive control network (LECN, RECN) were selected as the region of interest, and the correlation coefficient with time series signals between these areas was measured to identify the functional connectivity. Between groups analysis was also used. The results revealed a significant difference in the strength of the functional connectivity of the executive control network between the two groups. In other words, decreased functional connectivity was found between the superior/middle frontal gyrus and the caudate, and between the superior/middle frontal gyrus and the superior parietal gyrus/angular gyrus in individuals with PHB. In addition, these functional Connectivities related to the severity of hypersexual behavior. The findings of this study suggest that the inability to control sexual impulses and arousal in individuals with PHB might be related to the reduced functional connectivity of executive control circuits.

The purpose of this study is to confirm the effect of the young generation's Fairness perception on the hopelessness at the present time when the hopelessness of the future that young generation is experiencing is growing with social interest. This study examined the mediating effects of the perceived control and moderating effect self-esteem between the fairness perception and the hopelessness of the young generation. For this purpose, the self-reporting data of 313 young people in their 20s and 30s were collected. The results were as follows: First, fairness awareness was positively correlated with perceived control and self-esteem, and the hopelessness was negatively correlated with fairness awareness, perceive control and self-esteem. Second, perceived control mediated between fairness perception and the hopelessness, Third, self-esteem moderated the relationship between the fairness perception and the hopelessness. The high self-esteem group showed little change in hopelessness due to fairness perception while the low self-esteem group showed a big change in hopelessness due to fairness perception, which means that high self-esteem plays a role in alleviating hopelessness when fairness perception is low. The results of this study can be used as basic data to plan ways to improve mental health and quality of life.

The purpose of the present study is to examine effects of anger expression and perceived emotional competence on school anger in adolescents. The participants were 304 high school students (134 males, 170 females). They were administered the anger-related subscales (anger-out, anger-in, and anger control) of the Korean Version of the State-Trait Anger Expression Inventory (STAXI-K), the Korean Version of Trait Meta-Mood Scale (K-TMMS), and the Korean Version of School Anger Inventory(SAI-K). The results showed that school anger positively correlated with anger-out and anger-in, and negatively correlated with anger control and perceived emotional competence. Neither interaction effects of anger-out and perceived emotional competence nor interaction effects of anger-in and perceived emotional competence on school anger were significant. On the contrary, interaction effects of anger control and perceived emotional competence on school anger were significant. The results of post-hoc analysis revealed that the effect of anger control on school anger was significant in the case of high perceived emotional competence but not significant in the case of low perceived emotional competence. Based on these results, it was suggested that psychological programs designed to reduce school anger in adolescents need effective measures to enhance not only anger control skills but also perceived emotional competence.

This study examined the influences of participation in the free semester on school life satisfaction and interest in classes and whether the effect persisted longitudinally. The participants were students from middle schools located in large cities: 451 students in the experimental group and 466 students in the control group. Only the students of the experimental group participated in the free semester. The data were collected at the end of the free semester for three years, and the results are as follows. First, the school life satisfaction of students in the experimental group was significantly higher than those in the control group until the second year but not in the third year. Second, there was no difference in interest in the main subject classes between the experimental and control groups until the third year. Third, students' interest in art and sports classes in the experimental group was significantly higher than those in the control group until the second year but not in the third year. These findings suggest that long-term planning and management of the institution rather than short-term introduction is required for the continuous effects of the free semester.

This paper examines a simultaneous determination of corporate control mechanisms, and its effects on firm performance. The corporate control mechanisms considered include the following; insider shareholding, institutional shareholding, the board of directors, dividend policy, and capital structure. This paper applies a simultaneous equation methodology and investigates the interdependence among the corporate control mechanisms. In the first part, the paper finds that firm-level variations of control mechanisms are large across time although average variations are relatively small. These variations are related to one another, which is confirmed by Granger causality test based on dynamic panel autoregression model. More specifically insider shareholding, institutional shareholding and outside director ratio cause each other. With regard to interdependence among the control mechanisms, 2SLS(two stage least squares) regression results show that insider shareholding and institutional shareholding are substitutes while institutional shareholding acts as complements to the ratio of outside members in the board of directors. Then in the second part, the paper examines the relationship between firm performance and corporate governance. Firm performance, measured by Tobin's Q, has a positive association with leverage ratio while that has a negative relation to outside director ratio. This suggests that there may be a room for reforming corporate governance in Korea. Specifically it is necessary to enhance the independence of the outside directors.
