The hacking threats made against the Korea Hydro & Nuclear Power(KNDP) and the leakage of critical information on nuclear power safety raised the public awareness on the importance of protecting and managing national infrastructure necessary for sustaining the state and society. Cyber security activities and relevant institutions in the ROK, however, are still insufficient, because of which there is a possibility that similar incidents would reoccur and cause serious damages. Hence, a grave and direct threat is posed to the national security of the ROK. In this thesis, I would like to give my analysis and assessment on the recent cyber intrusions against infrastructure at home and abroad, measures established in response and their implementation, and the deficiency of the existing infrastructure protection system ; and lastly propose measures to reinforce infrastructure protection of the ROK.

The purpose of this study was to keep the Security Control Center, which operates under a shift system, uninterrupted during the COVID-19 virus epidemic. Security facilities responding to cybersecurity threats are essential security facilities that must be operated 24 hours a day, 365 days a day in real time, and are critical to security operations and management. If security facilities such as infectious disease epidemic, system failure, and physical impact are closed or affected, they cannot respond to real-time cyberattacks and can be fatal to security issues. Recently, there have been cases in which security system facilities cannot be operated, such as the closure of facilities due to the COVID-19 virus epidemic and the availability of security systems due to the rainy season, and other cases need to be prepared. In this paper, we propose a plan to configure a security system facility as a multiplexing facility and operate it as an alternative in the event of a closed situation.

This study choose the Criteria by conducting survey questionnaire of expertise, ANP analysis, and reviewing literature to samples of School Zone in a synthetic and reasonable way. It draws the estimating factors including a variety of existing aspects (user, facility, operation and management, and education and institution) from the analyses and applies ANP to reflect the decision making process. The results show as follows: first, first level of weights presents proportion of 'facility' and 'user' takes 65% of total weights. It implies that the facility protects children from obstacles is the top priority of the settings. second, the second level of weights present similar importance with the first level. Facility management, road to school, surroundings, safety facility, decelerating facility hold approximately 72% of overall levels. This indicates that improving and repairing surroundings, and safety and decelerating facility are the first priority to consider. These estimating indicators will be properly utilized to rationally appoint prevention zone with reflecting various factors and social class.

This study aimed to investigate the positive and negative appraisals of care work held by care workers in elderly care facilities and to analyze the mediating effect of care worker's appraisals of care work on the relationship between job environment and service quality. For the purpose of the study, the data were collected from 298 care workers by using non-random and purpose sampling method. The results of the study showed job environment was a significant predictor in explaining in the variances of care work appraisal and service quality. In addition, care worker's positive and negative appraisals of care work were statistically significant mediators in the association of between job environment and service quality. Finding of the study indicated that service quality could be improved by not only improving job environment but also strengthening care worker's positive appraisal of care work. Finally, based on the findings of the study, implications and limitations of the study were discussed.

Accidents involving deaths of children and pedestrians continue to occur in child protection zones, also known as school zones. Over the three years from 2019 to 2021, 11 child deaths occurred in school zones in Korea. In December 2022, a fatal accident occurred among an elementary school student in a school zone near an elementary school in Gangnam-gu, Seoul. In April 2023, an accident occurred in which an elementary school student died in a school zone near Seo-gu Middle School in Daejeon and an elementary school in Yeongdo-gu, Busan. Until recently, child deaths continued to occur on sidewalks in child protection zones. It is time to closely review the status of safety facilities installed in school zones and related regulations. We investigated and analyzed the current status of safety facilities and related regulations installed on sidewalks in child protection zones in Korea, and identified matters necessary for institutional improvement regarding safety facilities for sidewalks in child protection zones.
