There has been a growing number of research about children's development indicators and child well-being indicators. After the Convention on the Rights of the Child (CRC) and concluding observations on the second report of Korea, the effort to monitor and measure children's rights and the use of child rights indicators has increased within policy and academic research. However, few indicators provide a realization of children's rights. The purpose of this paper was to analyze children's own perceptions of their rights and to develop a children's rights index to measure children's rights. In this study, a children's rights index was developed from 38 indicators categorized into nine components and four domains (survival rights, development rights, protection rights, and participation rights) to measure children's rights. Data were gathered from 17,000 elementary and middle school children and their parents in 16 cities. The survey revealed significant differences in the children's rights index by region and age group. There was also a correlation between the economic circumstances of both households and communities and the children's rights index. In the light of the findings, it is suggested that there is a need to increase public investment on children and to raise awareness of children's rights in order to improve children's rights and to decrease disparity.

This study examined the overall effect size of the batterer intervention programs aimed at reducing violent behavior. This study calculated the 18 results and the 115 effect sizes of 11 theses published from 2000 to 2017 in Korea. It was demonstrated that the effect of an offender's program on the change in violent behavior was significant at both the practical and treatment level. The effect size was high in the order of control behavior, emotional violence, and physical violence. The effects of dependent variables other than violence were also researched. The batterer program positively changed the participant's attitudes in terms of sex-role and partner violence. Furthermore, it decreased the level of anger and depression, and enhanced self-esteem and communication skills thus increasing satisfaction in marital relationships. In addition, this study examined the factors that influence the effect of the offender's program in terms of the decrease of violent behavior. Upon analysis, it was examined that the moderating effect was great in the approach model and counsel form. More specifically, it was revealed that the feminist-cognitive behavioral models had a greater effect than the compromise model or single model. In terms of counsel forms, group counseling formed only of male offenders had greater effect than couples treatment group. Based on these findings, this study discussed the practical means for increasing the effect of batterer intervention programs.

Many patients with dizziness present with a symptom pattern that does not reveal the cause by neurotologic diagnostic approaches. In such cases, the physician frequently diagnoses psychogenic dizziness. Psychogenic dizziness is not characterized by true vertigo, and occurs in combination with other psychiatric symptom cluster. One out of two to four patients with dizziness are psychogenic dizziness. But there are few concern about this including clinical practice and study in Korea. I wrote this paper to increase concerning and attending to this for psychiatrists in Korea. I reviewed etiology including biological and psychological relations between dizziness and psychiatric disorder(especially anxiety), diagnostic approaches of, characteristics of dizziness of various psychiatric disorders related to, and the treatment of psychogenic dizziness. I also briefly reviewed the central and peripheral dizziness for psychiatrists. I suggest psychiatrists and clinicians in the psychosomatic field in Korea to acknowledge, concern, and attend to psychogenic dizziness. In turn, it will be helpful to well treat the patients with psychogenic dizziness.

This study focuses on the ICT literacy, the perceived value of ICT utilization, and the perceived use of ICT environment as the factors influencing the activation of ICT using classes, in order to identify how these differences affect intended use of ICT. A total of 3,942 high school teachers participated in the survey. Two factor analyses were conducted to verify and check the validities of measurement items for independent and dependent variables. With the research questions, a multiple regression analysis was implemented to verify the predictive power of the independent variables on the teachers' ICT utilization. All the independent variables set in the research issue had a significant influence on the intended use of ICT, which is a dependent variable. ICT utilization was found as the most influential variables followed by the perceived value of ICT utilization, the affective domain of ICT literacy, and the psychomotor domain of ICT literacy, the cognitive domain of ICT literacy, and the perceived use of ICT environment. In order to enhance teachers' ICT utilization in school settings, teachers should understand the educational value of ICT utilization and recognize its necessity and importance.

In this paper, we propose a method for finding feature subsets that are effective for classification in an input dataset by using a multi-agent reinforcement learning method. In the field of machine learning, it is crucial to find features suitable for classification. A dataset may have numerous features; while some features may be effective for classification or prediction, others may have little or rather negative effects on results. In machine learning problems, feature selection for increasing classification or prediction accuracy is a critical problem. To solve this problem, we proposed a feature selection method based on reinforced learning. Each feature has one agent, which determines whether the feature is selected. After obtaining corresponding rewards for each feature that is selected, but not by the agents, the Q-value of each agent is updated by comparing the rewards. The reward comparison of the two subsets helps agents determine whether their actions were right. These processes are performed as many times as the number of episodes, and finally, features are selected. As a result of applying this method to the Wisconsin Breast Cancer, Spambase, Musk, and Colon Cancer datasets, accuracy improvements of 0.0385, 0.0904, 0.1252 and 0.2055 were shown, respectively, and finally, classification accuracies of 0.9789, 0.9311, 0.9691 and 0.9474 were achieved, respectively. It was proved that our proposed method could properly select features that were effective for classification and increase classification accuracy.

While universities are making every effort to improve the housing welfare of university students by establishing new dormitories, the construction of school dormitories has intensified the conflict with other certified real estate businesses on the basis of their right to survival. Thus, it is necessary to analyze the causality in the conflict to coherently understand the conflict between these stakeholders. To do so, this study conducted a survey questionnaire on certified real estate businesses in the vicinity of private universities with dormitories in the metropolitan area. This study targeted licensed real estate brokerage agencies that conclude rental contracts in view of different stances, and control the real estate rental market by controling their conflict. Investigated the influence relationship between universities and licensed real estate brokerage agencies in relation to construction of private university dormitories and the effect of this conflict on management performance of licensed real estate brokerage agencies, and analyzed the relationship among relevant variables to see if their dormitory recognitions have a moderating effect. In addition to analyzing the causality of conflict level (perceived conflict, expressed conflict), conflict management, conflict outcome, and management performance, the study also verified the moderating effect of perception on dormitory and the mediating effect of conflict management. The results showed that conflict level had a negative (-) effect on conflict management, while the perceived conflict and conflict management of the conflict level had a negative (-) effect on the conflict outcome. In the relationship between perceived conflict and conflict outcome, conflict management had a complete mediating effect while expressed conflict had a partial mediating effect. Lastly, the perception of university dormitories did not have a moderating effect for the influence of conflict management on conflict outcome.

Due to COVID-19, user instruction programs could not be conducted face-to-face, and the sessions have been moved online. The present study attempted to investigate how online user instruction influences the information literacy ability of college students. The study randomly selected college students (N=50) who completed online user instruction sessions and college college students (N=50) who did not complete them among freshment who went to to college in 2020 to measure their information literacy abilities. For this study, a tool for measuring information literacy abilities was developed by referring to several previous studies. The measurement results were analyzed by the independent samples t-test, and significant differences were found between students who completed online user instruction sessions and those who did not. The findings of the study have confirmed that it is effective in enhancing library users' information literacy abilities to provide user instruction online under the COVID-19 situation, and even in post-COVID 19 times, which helps them appropriately utilize the characteristics of digital libraries. The information literacy measurement tool used in the present study was developed to evaluate online information literacy, and thus contributed to the extension of the literature of digital information literacy and user instruction. The present study provided practical implications for how academic libraries will promote information services to cope with environmental changes in which contact-free (untact) services are obliged.

The purpose of this study is to investigate the effect of gardening programs using vertical gardens on helplessness, depression, and self-esteem in patients with chronic mental disorders. This study was applied to 21 patients with chronic mental disorder who were admitted to the rehabilitation hospital of E Hospital in Seoul from June to October 2018. The group was treated as an experimental group (N = 21) 5 times a week. For 20 weeks, each session lasted 30 minutes. Patients in the experimental group programmed 4 sessions of general occupational therapy, which combined treatments to improve cognition and training, and 1 session of a horticultural program using a vertical garden. Helplessness, depression, and self-esteem were evaluated for pre and post evaluation of the horticultural program. After completing the program, the average score of helplessness in the experimental group decreased by 0.91 points from 47.38 to 46.47, and there was a statistically significant change (p=0.043). The mean score of depression in the experimental group was 9.23 before and after 9.08, which was statistically significant (p = 0.035). The average score of self-esteem in the experimental group increased by 3.14 points from 27.99 to 31.13 at a statistically significant level (p = 0.001). This result suggests that a gardening program using vertical gardens has an effect on helplessness, depression, and self-esteem in patients with chronic mental disorders. And this means that long-term plans and effective programs for recovery from chronic mental disorders to the community are needed. With a horticultural work program using a vertical garden, the helplessness of the mentally impaired in a closed treatment space is restored, and such treatment space needs to be increased.

The pilot project for type diversification of self-sufficient support center that convert the centre corporation into social cooperative was introduced in 2015. That aimed to increase the number of participants of self-sufficient programmes and to create more jobs for the working poor through expanding the center's autonomy of usage of budget and arrangement of self-sufficient programmes. This study analyzed the organization transmitting processes and changes of the centers took part in the pilot project, then aimed to suggest the improvement schemes to be helpful for reinforcing positive efforts and removing obstacles in the process converting. The results show that converting into social cooperative is a choice for the sustainability of the centers led by surroundings rather than self-initiated plan. There are some positive changes that are increasing the enterprising spirit and obligation of the center staff. Further more, the cooperation with other community organizations is enhanced based on achieving regional recognition, and support of local governments and the opportunity for new businesses are expanded. However, these are very limited in the regions where social economy is undeveloped. Eventually, we should seek the development schemes of the pilot project considering the reduction of the number of participants in self-sufficient programmes and decreasing of their ability to work, even if some positive aspects are revealed.
