This study examines the Gyeongju Seokguram Grotto restoration project (1961-1962) by architect Kim Chung Up (1922-1988) and introduces the documents he wrote at the time of planning. The study highlights Kim's Plan attempt to adopt Buckminster Fuller's idea of the Geodesic Dome, while inheriting the architect Pai Ki Hyung's previous design plan which was nullified. As Seokguram Grotto's water leak and deterioration issues have been brought up, the four-times survey was carried out by experts team between 1958 and 1960, under Ministry of Education's direction. Pai designed an initial restoration plan based on the survey's result, which was a double-dome structure with a concrete film on the outer periphery as a way to protect Seokguram Grotto in January 1961. However, as drawbacks, such as the heavy load of the concrete dome, and non-installation of entrance hall, have been indicated in the review process, the Cultural Properties Committee rejected the plan. Subsequently, Kim was appointed as the supervisor of the second restoration project. Kim drew up a process management schedule to be implemented from August 1961 to December 1963 and designed the conception plans for the second restoration design. This study analyzes Kim's Plan by examining sketches, site plans, floor plans, and sections. Kim planned to maintain the idea of the double-dome structure proposed by Pai while applying Buckminster Fuller's idea of the Geodesic Dome. Kim planned to lighten the dome structure by applying a steel-frame Geodesic Dome so that the dome structure could be supported by its own. The study is expected to reclaim the omitted parts from Seokguram Grotto's historical description and Kim's careers.

This study introduced the compact grouting method that can be used for improving soft ground and restoring buildings with unequal subsidence. The pump used in the traditional compact grouting method is a system that injects one hole each, which reduces the construction efficiency, and the analog injection method manually manages the construction by field workers, making it difficult to manage consistent quality. Pump and quality control system were developed to solve problems in existing construction. Since field supervisor determines amount of injected materials by using analog equipment and controls manually, it is difficult to manage consistent quality of construction. Therefore, the quality control system was developed in order to solve that problem. The quality control system consists of automatic mixing system of injection materials, multiple simultaneous injection pumps, and injection management monitoring system. Performance of the quality control system was verified through on-site testing, and ground improvement performance was verified through quality testing after testing and testing of the compact grouting method. Therefore, it is expected that the integrated quality control system developed will improve the quality assurance and efficiency and stability of construction at sites where construction and quality verification are difficult.

Objectives: While employed mothers' use of maternity and parental leave has increased, the contexts that facilitate or hinder mothers' leave policy use have been under examined. The purpose of this study was to explore mothers' experiences of using maternity and parental leave. Method: Twenty-two mothers with young child under age three participated in this study. Results: All 22 mothers used maternity leave and 12 mothers used parental leave. Three main themes were identified: different experiences of maternity leave, experiences of parental leave, and skepticism about the leave policy but with some hope that it will improve. Regarding the mothers' experiences of maternity leave, the mothers thought that maternity leave was easily accessible but some mothers still felt guilty for using maternity leave. They also prepared for their work gap before the leave to avoid harming their colleagues. Accessibility to parental leave varied according to the characteristics of the organizations (i.e., family-friendly organization culture, supportive supervisor) and family contexts (i.e., availability of child care from family members, financial issues). The mothers perceived that while parental leave helps working mothers coordinate their family and work life, it is not as accessible as maternity leave in Korea. They suggested extending the maternity leave duration and improving accessibility to parental leave. Conclusions: These findings suggest that policy support is warranted to help employed mothers with young children remain in the workforce. This study also has implications for supporting employed mothers' work and family life.

In this paper, we propose a clustered algorithm that possible more efficient user distinction within clustering using context-aware attribute information. In typically, the data provided to classify interrelationships within cluster information in the process of clustering data will be as a degrade factor if new or newly processing information is treated as contaminated information in comparative information. In this paper, we have developed a clustering algorithm that can extract user's recognition information to solve this problem in using K-means algorithm. The proposed algorithm analyzes the user's clustering attributed parameters from user clusters using accumulated information and clustering according to their attributes. The results of the simulation with the proposed algorithm showed that the user management system was more adaptable in terms of classifying and maintaining multiple users in clusters.

This study was to verify the effect of the supervisor's abusive supervision on turnover intention and the mediating role of emotional stress and work engagement in the process. The online survey was conducted on 317 employees and the data were analyzed through SPSS Macro and bootstrapping. The results are as follows: the correlation between abusive supervision, emotional stress, work engagement and turnover intention was confirmed to be statistically significant, and dual mediating effect of emotional stress and work engagement was statistically significant. This study showed meaningful results on the path of the abusive supervision and turnover intention. Further studies with longitudinal method and in-depth studies on factors influencing pathways will be needed to verify substantially the dual mediating effect.

This paper propose a clustered algorithm that possible more efficient COVID-19 disease learning prediction within clustering using context-aware attribute information. In typically, clustering of COVID-19 diseases provides to classify interrelationships within disease cluster information in the clustering process. The clustering data will be as a degrade factor if new or newly processing information during treated as contaminated factors in comparative interrelationships information. In this paper, we have shown the solving the problems and developed a clustering algorithm that can extracting disease correlation information in using K-means algorithm. According to their attributes from disease clusters using accumulated information and interrelationships clustering, the proposed algorithm analyzes the disease correlation clustering possible and centering points. The proposed algorithm showed improved adaptability to prediction accuracy of the classification management system in terms of learning as a group of multiple disease attribute information of COVID-19 through the applied simulation results.

Purpose: The purpose of this study was to understand the effects of infection control fatigue and social support on burnout among nurses during the Coronavirus Disease 2019 (COVID-19) pandemic. Methods: This study is a descriptive survey study designed to confirm the effects of nurses' infection control fatigue and social support on burnout among nurses during the COVID-19 pandemic. The collected data were analyzed using frequency, percentage, mean, standard devia analyzed using frequency, percentage, mean, standard deviation, independent t-test, One-way ANOVA, Scheffe test, Pearson's correlation coefficient, and stepwise multiple regression analysis using SPSS Statistics 26.0. Results: An analysis of the correlations between fatigue from infection control, social support, and burnout showed a positive correlation between burnout and fatigue from infection control (r=.39, p<.001), and a negative correlation between burnout and social support (r=-.29, p<.001). Conflict and lack of support due to uncertain circumstances (β=.51, p<.001), support from supervisor's (β=-.22, p<.001), and experience of infection management education during the previous 1year (β=-.15, p=.007) were identified as the factors that influenced burnout among nurses, and explained 39.0% of the variance in burnout. Conclusion: The results of this study demonstrate that fatigue from infection control and social support influence burnout levels among nurses, which suggests the need to establish a new kind of work culture. Additionally, the findings call for the development and implementation of interventional programs that can reduce fatigue from infection control and increase social support for nurses.

One of the organizational characteristics in the modern society is the emphasis placed upon individual autonomy in an effort to promote and develop each member's morale as well as the efficiency in personnel management. Therefore, it can be understood that the importance of "Self" is recognized in work places and the leadership of supervisors and each member's self-management and control are also emphasized, leading to establishment of the "Self-leadership" concept. In this study, the effect of the Transformational Leadership of the supervisors on the subordinates' Self-leadership was analyzed and the causal factor of organizational support in the relationship between Transformational Leadership and Self-leadership was defined. A survey was conducted with 182 security officials at the National Assembly and the following results were obtained. First, Transformational Leadership had a positive effect on Self-leadership and the Transformational Leadership of the supervisors had a statistically significant impact on the organizational support awareness. Furthermore, organizational support showed a statistically significant mediator effect in the relationship between the Transformational Leadership of the supervisors and the Self-leadership of the subordinates. Finally, future directions in regard to the personnel management system were suggested.
