The Korea Coast Guard(KCG) is the only comprehensive maritime administrative agency in Korea that performs various tasks taking place in the ocean, including rescue operations, disaster management, policing, Drug and smuggling crackdown, responding to Response to invasion of maritime territory, environmental conservation, and maritime security. It is vital to inform the public of the role and mission of KCG as the only comprehensive maritime administrative agency in Korea. However, most citizens, excluding residents of the coastal and island areas, have little knowledge of the security administration services of the KCG due to lack of exposure. This study reviewed the KCG's public relations(PR) organization and current status using KCG promotional materials, diagnosed the actual conditions of KCG's PR, and suggested ways to improve public relations activities through a questionnaire survey of public relations personnel. Through literature research and questionnaire survey, the KCG's public relations status was estimated and the measures to enhance publicity was derived as follows: strengthening the PR organization by reinforcing the personnel in charge of PR, improving customized promotion by clarifying the promotion strategy according to the promotion target, enhancing job training for PR personnel, and increasing the interest and support of commanders and internal members in charge of PR work.

The purpose of this study is to examine the status of RDA adoption in Korea and the perception of university librarians on RDA adoption. For this purpose, the adoption status of two libraries that adopted RDA among domestic libraries was analyzed. In addition, interviews were conducted with eight university librarians, and narrative responses related to the adoption of RDA were collected and analyzed. As a result of the interview survey, the research participants recognized that the concept of RDA is very difficult and abstract, there are few implementation cases where RDA is applied, and that it would be very difficult to adopt RDA due to the personnel and budget conditions of the local library. The RDA adoption method recognized by the research participants is to improve RDA awareness, conduct RDA education, prepare guidelines for constructing hybrid bibliographic records when RDA is adopted, operate an RDA pilot institution, and establish a performance model. In addition, research participants need coordination with companies for implementation, prefer to change a specific point in time rather than batch retroactive conversion, discover success stories, establish RDA-related online channels, build and utilize national authority DB, and use the national budget and system support. In this study, based on the research results, a plan to adopt RDA for university libraries in Korea was presented.

The purpose of this study is to examine the perception of librarians on the role of public libraries related to disasters. For this purpose, the study conducted an online survey for librarian. The survey is composed of 34 questions, including the questions asking librarians' perceptions about the roles of public libraries related to the disasters derived from literature review. The research results are as follows; First, although librarians were not well aware of the roles of public libraries related to disasters, they generally supported the necessity of the role and evaluated the benefits of the role highly. Second, librarians recognized the necessity of the role of the library in the following order of importance; psycho-emotional support for citizens who have experienced disasters; cooperation with disaster support agencies; disaster shelter; disaster information service; archiving disaster experiences of residents; outreach services; community support. Third, librarians recognized that psycho-emotional support services for residents suffering from disasters were the most necessary and beneficial to residents. Fourth, librarians' perceptions of disaster-related library roles changed based on their position and the type of library they belong to. On the basis of these results, the research discussed and suggested what roles each public library should play and what services it should plan, and how it should be implemented during the disaster.

This study was aimed at exploring the parenting experience of fathers in single parent families as well as comprehensively determining their parenting experiences and the various parenting resources and support systems that have emerged in the process. The subjects were five divorced fathers who had not remarried and had been raising their children on their own. This qualitative case study involved data collect through in-depth interviews. The inter-case analyses derived two topics, five categories, and 17 concepts related to the issues of interest. The results indicated, that, first, there was "psychological confusion in the early stages of parenting" because of the sudden onset of this responsibility after divorce. Second, in the parenting experience, the fathers felt that "family survival was at stake". Third the support systems that the fathers had in raising single parent families were "social resources" made available through workplaces, acquaintances, institutions, and the government. Such systems also took the form of "family resources" including brothers and parents. An "internal resource" was the presence of children along with psychological sources of support, such as responsibility and the satisfaction experienced by the fathers through parenting. This study, uncovered the reality, resources, and support systems of fathers in single families. It is meaningful in that it will serve as a basis for supporting practical measures and educational interventions for fathers in single-parent households.

In this study, radiation exposure doses were measured in the course of clinical practice of radiation workers, radiological technologists in the radiation-related worker group, and preliminary-radiological technologists who were classified as frequent visitors. Radiological technologists who worked in the radiation area of C University Hospital in Incheon for a year from January 2021 and 121 students who completed clinical practice at the same medical institution from July 1 to August 31 were the subjects of the study. The nominal risk factor based on ICRP 103 was used to evaluate the probability of side effects due to the exposure dose to the lungs, which are organs at risk of damage due to radiation exposure dose. During the clinical practice period, radiology students, who were classified as frequent visitors, had a surface dose of 0.98 ± 0.14 mSv and a deep dose of 0.93 ± 0.14 mSv. In other words, 6.7 per 1,000,000 for shallow dose and 6.4 per 1,000,000 for deep dose were found to have side effects due to exposure to the lungs. This is a value in terms of exposure dose in one year. Considering that the radiation (science) education course is 3 or 4 years, systematic management and attention to prospective radiation workers who are going to clinical practice are required, and the stochastic effect of radiation In relation to this, it is considered that it will be used as basic data for radiation safety management.

In this study, the recognition of child abuse and neglect (CAN) and reporting attitudes of general dentists and pediatric dentists in Korea were estimated. A survey was conducted among dentists working at clinics or university hospitals, including interns and residents at dental hospital training institutions. The questionnaire, consisting of 32 questions and detailed questions, subdivided into 'general characteristics of respondents', 'CAN', 'CAN report', 'laws to CAN', 'countermeasures against CAN'. The survey was conducted using a messenger, and 176 respondents' answers were analyzed. The recognition of CAN showed high scores in the order of physical abuse, neglect, and emotional abuse. The positive attitude toward reporting CAN had a higher score than the negative attitude. Of the total respondents, 19 said they reported child abuse, and 18 said they were suspected of child abuse but hesitated to report it. Among the laws related to CAN, the protection measures for CAN reporters and the protocol for CAN showed low awareness. Since then, they have wanted to know how to find abused children and how to deal with them in education. This study is expected to be used as data to improve dentists' awareness and consciousness of CAN in the future.

The AERMOD model was the most used, accounting for 89.0%, based on the analysis of the environmental impact assessment reports published in the Environmental Impact Assessment Information Support System (EIASS) between 2021 and 2022. The mismatch of versions between AERMET and AERMOD was found to be 25.3%. There was the operational time discrepancy of 50.6% from industrial complexes, urban development projects between used in the model and applied in estimating pollutant emissions. The results of applying various versions of the AERMET and AERMOD models to both area sources and point sources in both simple and complex terrain in the Gunsan area showed similar values after AERMOD version 12 (15181). Emissions are assessed as 24-hour operation, and the predicted concentration in both simple and complex terrain when using the variable emission coefficient option that applies an 8-hour daytime operation in the model is lowered by 37.42% ~ 74.27% for area sources and by 32.06% ~ 54.45% for point sources. Therefore, to prevent the error in using the variable emission coefficient, it is required to clearly present the emission calculation process and provide a detailed explanation of the composition of modeling input data in the environmental impact assessment reports. Also, thorough reviews by special institutions are essential.

The purpose of this study was to investigate attitudes toward aging and depression among elderly welfare facility users. For this purpose, a questionnaire-based survey was conducted with 280 elderly participants in the facilities of 15 institutions in Gyeonggi-do. In total, 258 data points were used for analysis. The measuring instruments used an attitude scale and depression scale for aging. The results of this study are as follows. First, there was no difference in attitude toward aging and depression among elderly welfare institution users by gender. Second, attitudes toward aging among elderly welfare facility users were also assessed according to final educational background. Positive attitudes in general (lack of depression) and positive attitudes toward aging were found to be higher with a higher rate of final academic completion. Third, attitudes toward aging were assessed according to experience with welfare facilities among the elderly, and it was found that depression has a significant impact on perceptions of physical change caused by aging. As a result, even when attitudes toward aging are generally negative, an elderly person cannot be judged to be depressed because this is highly related to final academic completion. Therapists working in welfare facilities for the elderly are more likely to have negative attitudes toward aging and depression when the number of facilities used is lower.

This study was carried out to determine agronomic and genetic characteristics of the production process in tropical yams(Dioscorea alata L.). To make clear the possibility of cultivation of tropical yams in the Suwon area, the growth of the aboveground parts and the enlargement of tuber of Dioscorea alata, were investigated. The aboveground parts of the plants whose sprouted mother tuber were planted in late April were grown slowly until the 70-days after planting and grown rapidly after. From about 50-days after plantation, total length of vines slowly decreased due to the burning of the branch vines of lower modes. With regard to the branching progressed to 4th for the solo yam and to 6th for purple yam. The secondary branches tended to grow better. When the formation of daughter tubers was observed at the 50-days after planting, their enlargement was very slow. The rapid growth of tubers began at the 40-days and continued to the 90-days. General components such as protein, fiber, and lipid were higher in D. opposita rather than in D. alata. Hardness of D. alata was 2696.2 while that of D. opposita was 4946.9. Lightness of D. alata was 73.99, being higher than that of D. opposita.

Research using AI and big data is also being actively conducted in the health and medical fields such as disease diagnosis and treatment. Most of the existing research data used cohort data from research institutes or some patient data. In this paper, the difference in the prediction rate of survival and the factors affecting survival between breast cancer patients in their 40~50s and other age groups was revealed using health insurance review claim data held by the HIRA. As a result, the accuracy of predicting patients' survival was 0.93 on average in their 40~50s, higher than 0.86 in their 60~80s. In terms of that factor, the number of treatments was high for those in their 40~50s, and age was high for those in their 60~80s. Performance comparison with previous studies, the average precision was 0.90, which was higher than 0.81 of the existing paper. As a result of performance comparison by applied algorithm, the overall average precision of Decision Tree, Random Forest, and Gradient Boosting was 0.90, and the recall was 1.0, and the precision of multi-layer perceptrons was 0.89, and the recall was 1.0. I hope that more research will be conducted using machine learning automation(Auto ML) tools for non-professionals to enhance the use of the value for health insurance review claim data held by the HIRA.
