Functional brain imaging techniques have been used to diagnose psychiatric disorders such as dementia, depression, and autism. Recently, these techniques have also been actively used to study hearing loss. The present study reviewed the application of the functional brain imaging techniques in auditory research, especially those focusing on hearing loss, over the past decade. EEG, fMRI, fNIRS, MEG, and PET have been utilized in auditory research, and the number of research studies using these techniques has been increasing. In particular, fMRI and EEG were the most frequently used technique in auditory research. EEG studies mostly used event-related designs to analyze the direct relationship between stimulus and the related response, and in fMRI studies, resting-state functional connectivity and block designs were utilized to analyze alterations in brain functionality in hearing-related areas. In terms of age, while studies involving children mainly focused on congenital and pre- and post-lingual hearing loss to analyze developmental characteristics with and without hearing loss, those involving adults focused on age-related hearing loss to investigate changes in the characteristics of the brain based on the presence of hearing loss and the use of a hearing device. Overall, ranging from EEG to PET, various functional brain imaging techniques have been used in auditory research, but it is difficult to perform a comprehensive analysis due to the lack of consistency in experimental designs, analysis methods, and participant characteristics. Thus, it is necessary to develop standardized research protocols to obtain high-quality clinical and research evidence.

Objectives: The proportion of those working beyond 53 hours a week in 2018 has reached 16.8% of the total number of workers in the Republic of Korea (Statistics Korea, 2018). Although there are many studies that have dealt with the correlation of long working hours and increasing risk of work-related health problems, studies dealing with the factors impacting work-related health problems of workers according to their working hours are few. This study aims to ascertain factors impacting work-related health problems of workers based on their working hours through thorough research on their work environment. Methods: Necessary factors for this study were extracted from 'the 4th Korean Working Conditions Survey to analyze details on normal characteristics and work environments used for the study analysis, work hours, and health problems related to work. Results: The results are as follows: First, men showed a greater probability of exposure to work-related health problems than did women, especially in the 50s age group, which showed the highest potential for health problems from work among age groups. Second, service providers and sales professionals showed a higher probability of work-related health problems. Third, for the work environment, health problems at work related to vibration, noise, chemical and poison exposure, exhaustion, pain, standing position, and repeated motion showed a higher probability if the work hours are long. Conclusions: This study suggests that the minimization of overtime labor would prevent work-related health problems and diseases, improve the well-being of workers, and decrease the negative impact on workers in the subject area.

Purpose: The purpose of this study was to analyze the trends and characteristics of infection-related patient safety incident reporting before and during the coronavirus disease 2019 (COVID-19) pandemic in Korea, and to provide basic data for preventing infection-related patient safety incidents and improving their management. Methods: A cross-sectional analysis of secondary national data (Patient Safety Reporting Data) was conducted. In total, 517 infection-related patient safety incidents reported from 2018 to 2021 were analyzed. Changes in the number of reports before and during the COVID-19 pandemic and differences in variables related to infection-related patient safety incidents were analyzed using the chi-square test and independent t-test in SPSS 29.0. Results: This study found that infection-related patient safety incidents decreased during the COVID-19 pandemic compared to before the pandemic. Furthermore, incident-related characteristics, such as the type of healthcare organization, severity of harm, and post-incident actions, changed during the COVID-19 pandemic. Conclusion: The many changes in the infection control system and practices during the COVID-19 pandemic may have contributed to a decrease in the reporting of infection-related patient safety incidents. It is hoped that longitudinal studies on patient safety incidents related to the pandemic and analytical studies on factors influencing patient safety incidents will continue to be conducted to prevent and improve patient safety incidents.

This study aims to examine the formation of Japanese Social Welfare Studies based on Michel Foucault's Genealogical perspective related with power-knowledge relationships. Namely, this study reveals that Japanese Social Welfare Studies has been built through interactions of power-knowledge relationships in the context of scholars' individual experience and social circumstances. For the study, 40 literary works of Japanese Social Welfare Studies written by 26 authors have been selected to construct the resourceful main data. From the main data, 671 concepts have been abstracted and shortly introduced in 3 parts: authors' individual experiences, social circumstances related with Social Welfare Studies, and composed contents of Social Welfare Studies. The resulted Genealogy of Japanese Social Welfare Studies from the categorization is emerged and analyzed as follows: 1) scholars' individual experience and dichotomous formation of Social Welfare Studies, 2) missionary's activities and development of social welfare, 3) searching essence of social welfare and formation of scholars' genealogy, 4) prosecution of wars including ups and downs of economy and social welfare, and 5) expansion of social welfare and enlarging of Social Welfare studies.

Objectives We will provide basic information on bee venom clinical tests and aid the practical use of bee venom in such tests, through examination of RCT research related to bee venom that was reported domestically. Methods We collected 365 articles on Bee venom study result from the OASIS system using the Keyword 'bee venom, apitoxin, apitherapy, bee sting'. The initially selected theses were primarily screened for clinical research. Out of these, case studies and non randomized controlled trial (non-RCT) were ruled out. As a result, 39 studies of randomized controlled trial (RCT) research were chosen as the subjects of study. Results RCT research related to bee venom was first presented in 2003, and 39 studies have been published until 2012. 18 studies were tests to confirm the effectiveness of bee venom, 7 studies were comparisons between SBV and BV, and 13 studies were comparisons with other types of treatment. Research conducted through appropriate randomization methods were 20 studies, and inappropriate randomization methods were used in 19 studies. In therms of Jadad score, 12 studies received 4~5 points, 15 studies received 1-3 points, and 12 studies received zero point. Conclusions In order to assure good quality RCT research, appropriate guidelines should be provided, and proper evaluation standards should be established. In-depth study is needed concerning the difference of responses to treatment according to the types of treatment received. A standardization of treatment should be reached as a result.

This study examines the factors related to university students' positive beliefs about the consequences of maternal employment. A total of 338 university students in Seoul, Gyeong-gi, and Kyungnam area provided information about their socio-economic background, parents' employment history, achievement motivation, and gender egalitarian attitude. A two-way analysis of variance showed significant interaction effects of gender and grade on positive beliefs about the consequences of maternal employment. Multiple regression analyses by gender indicated that factors related with university students' positive beliefs about the consequences of maternal employment may differ by gender. For male students, grade, and socio-cultural gender egalitarian attitude were significantly related to positive beliefs about the consequences of maternal employment. For female students, grade, family monthly income, mother's employment during elementary school, and achievement motivation were related with positive beliefs about the consequences of maternal employment.

The purpose of this study was to investigate the role of anxiety in mediating the influence of family of origin characteristics on subsequent relationship processes. Using Bowenian theory as a foundation, this study examined the causal relationships among gender, religion, family of origin-fusion, intimacy, intimidation, personal-trait-anxiety, couple open communication and relationship satisfaction. Results of the path analysis indicated that: (a) gender, religion, family of origin-fusion, and family of origin-intimidation were directly related to personal-trait-anxiety, (b) personal-trait-anxiety was directly related to couple open communication and not related to relationship satisfaction, (c) couple open communication was directly related to relationship satisfaction, and (d) family of origin factors were not directly related to couple open communication and relationship satisfaction; rather, as it was expected, indirect associations, through the mediation of anxiety, were found. The results generally support Bowen's intergenerational process theory, which asserts that anxiety is the mediator of the process. Limitations of the current study and suggestions for further research were discussed.

Purpose The purpose of this study focused on adopting production systems in cognitive psychology to improve the extraction process of persuasive design characteristics for healthcare-related mobile applications. Design/Methodology/Approach A research approach with four stages was developed. We developed and updated the evaluation guideline for persuasive design characteristics (PDC). We tried to summarize and analyze each of 28 PDC and prepared related production rules. Verification process for both guideline approach and production system approach were performed. Top one hundred apps from both medical category and health and Fitness category were selected and evaluated by two approaches. By comparing the results of the two approaches, we tried to explain the improvement and reliability of introducing the production system in the PDC extraction process. Findings Based on the updated guideline for healthcare-related mobile applications, a production system in cognitive psychology was developed. By comparing the PDC extraction results by two approaches, production system showed a better improvement for evaluation precision and efficiency for decision-making process. The findings of this study can be used for researchers and app developers to apply production system to analyze, evaluate, and develop better healthcare-related apps with persuasion.

The purpose of this study was the development of a scale to assess the daily hassles of school age children. The subjects were 398 third and sixth grade children selected from elementary schools in Seoul, Inchon, Taejon, Kwangju and Pusan. Instruments included a questionnaire composed of a 96-item Daily Hassles Coping Scale, demographic questions, a 27-item Children's Depression Inventory, the 42-item Han & Yoo Daily Hassles Scale for Children, and a 30-item Children's Behavior Check List for mothers. Mean, %, ${\chi}^2$, Cramer's V, Cronbach's ${\alpha}$, factor analysis and Pearson's r were used for data analysis. 82 items from the 96-item Daily Hassles Coping Scale were selected through the item discriminant method. (Cramer's V discriminant coefficients ranged from .36 to .79). Five factors were extracted from the lst and 2nd factor analyses. Subscales were "parent-related," "friend-related I," "study-related," "friend-related II," and "teacher-related" stress. Criterion validity of the 82-item scale was confirmed through significant correlations with the Children's Depression Inventory (r=.55) and the Han & Yoo Daily Hassles Scale for Children (r=.22). Internal consistency of this scale was high, including internal reliability of subscales. These results confirm this scale as a valid and reliable measure of daily hassles of school age children.

The relationships of maternal childrearing behaviors and peer experiences to children's self-esteem were examined with a sample of 433 5th- and 6th-grade elementary school students (236 boys and 197 girls) and their mothers. Children answered the questionnaires on peer experience (victimization by peers and peer aggression) and self-esteem, and their mothers answered the questionnaires on maternal childrearing behaviors. Maternal warmth was significantly related to children's self-esteem both in boys and girls. The warmer their mothers, the higher the children's self-esteem. Maternal permissiveness/nonintervention was related to self-esteem only in boys; the more permissive/nonintervention the mothers, the lower the boys self-esteem. Peer experiences (victimization by peers and peer aggression) were significantly related to self-esteem both in boys and girls; the more victimization by peers and peer aggression, the lower their self-esteem. Maternal warmth was related to victimization by peers only in girls; the warmer the mothers, the less victimization by peers experienced by girls. The effect of maternal warmth on self-esteem was mediated by victimization by peers for girls, which indicates that maternal warmth doesn't have a direct influence but an indirect influence on victimization by peers of children. Victimization by peers was related to peer aggression both in boys and girls. The more victimization by peers they experienced, the more peer aggression they showed.
