This study is to discusses the relevance of social welfare in Freud's psychoanalytic theory. The results of the study are as follows. First, psychoanalytic theory details the client's family history and personal history to help them identify the characteristics of the problem they have today. At this time, social workers actively listen to clients and try to get various information.Second, when used in psychoanalytic techniques, the resistance of the client can be interpreted and analyzed to help the client maintain friendly relationships with the client.Third, psychoanalytic theory can properly apply the client's current state of mind by understanding the potential conflicts or emotions that exist in the client's unconscious mind. Fourth, during the process of intervention, social workers need to deal well with the client's transition response. This process allows social workers to observe the effect of reducing the stimuli that can cause nervousness in clients.In conclusion, all the techniques of interpretation used in psychoanalytic theory are, after all, techniques that help social workers improve clients' insight into their problems and help clients solve their psychological problems themselves. The psychoanalytic theory is widely applied in social welfare.

This study examined the value of the old roads and roadscapes as modern assets. Topographic maps of the two years (1916 and 1919, which were produced by the Japanese Government-General of Korea) and the digital topographic map produced in 2017, were analyzed. The total amount of roads that have survived for the past 100 years are located in 108 places and total 26.32km. After examining the remnants of the roads in YeongDo, the type of scenery experienced along the roads were classified into nine kinds. The place where a sequential scenery experience takes place due to the survival of the past, the experience is based on the transition of historical scenery, not the scenery of the present time. A new model that can preserve, manage and plan this scenery is required. Therefore, we propose a new landscape model that elevates the concept of gaze from a spatial concept to a spatiotemporal concept. Based on this model, we propose a conservation criterion of the landscape viewed on the road as a viewpoint. As a modern asset for the next 100 years of YeongDo, it is necessary to understand and preserve the meaning of the landscape and roadside scenery as a transit landscape network. The remnant of roads from 100 years ago suggests that the scenery on the road was has been maintained, and it is the historical landscape of the YeongDo area. Through the landscape conservation plan proposed in this study, it is expected that the historical roads and their landscape will be positioned as a modern asset and an aspect of local heritage, and the future conservation and management of the roads and roadscapes will continue.

This study aims to investigate the transition of the game rating system in Korea and to search for problems and improvement measures in the era of IARC game grade review. IARC(International Age Rating Coalition) is an International Classification Alliance, with 37 member organizations from 6 countries. In addition, IARC grants participating store-fronts autonomy to review game ratings. The method of deliberating games in Korea is proceeding with direct review by rating system and deliberation by IARC's own classification system. The problem of the rating system of the game is that the civilian becomes the subject, it relies on the questionnaire, and its side effects are caused by its own classification system. IARC guidelines can be developed to improve the game rating system, education on penalties and ratings for game developers, and management of participating front-stores. In conclusion, it may be dangerous to delegate rating authority to open market, and it is necessary to construct a discussion forum for ratings, including government and industry, game developers, users, and parents of under-age gamers. It is necessary to create a rating system for the game environment in Korea.

According to the United Nations Convention on the Law of the Sea (Article 94), the flag state must fulfill its overall role to ensure maritime safety and operate the ship inspection system as a related measure. The Korean government (Ministry of Ocean and Fisheries) has implemented policies for reducing marine accidents to promote maritime safety; however, the target goal has not been achieved. The ship inspection system is a measure to prevent marine accidents, and for the effective operation of the system, a sufficient understanding of the origin of the ship inspection system is required. In this study, the trend of the international ship inspection system was identified by analyzing ship inspection system origins and the history of the system's paradigm shift. The recent international ship inspection system paradigm confirms international standardization and the active safety management of ship companies are becoming increasingly prominent. Based on this, the introduction of the 'PDCA cycle-based self-inspection system' is presented to the current domestic ship inspection system. This is a new type of inspection system that establishes the roles of interested parties based on the basic philosophy of the ISO 9000 series to improve the ef ectiveness of maritime safety. Additionally, the necessity for a non-face-to-face ship inspection system has emerged because of the COVID-19 pandemic. Hence, the transition to a 'mobile application-based ship inspection system' is proposed to accommodate the rapid development of information communications technology.

Objective: Cage rearing has critical implications for the laying duck industry because it is convenient for feeding and management. However, caging stress is a type of chronic stress that induces maladaptation. Environmental stress responses have been extensively studied, but no detailed information is available about the comprehensive changes in plasma metabolites at different stages of caging stress in ducks. We designed this experiment to analyze the effects of caging stress on performance parameters and oxidative stress indexes in ducks. Methods: Liquid chromatography tandem mass spectrometry (LC/MS-MS) was used to determine the changes in metabolites in duck plasma at 5 (CR5), 10 (CR10), and 15 (CR15) days after cage rearing and traditional breeding (TB). The associated pathways of differentially altered metabolites were analyzed using Kyoto encyclopedia of genes and genomes (KEGG) database. Results: The results of this study indicate that caging stress decreased performance parameters, and the plasma total superoxide dismutase levels were increased in the CR10 group compared with the other groups. In addition, 1,431 metabolites were detected. Compared with the TB group, 134, 381, and 190 differentially produced metabolites were identified in the CR5, CR10, and CR15 groups, respectively. The results of principal component analysis (PCA) show that the selected components sufficiently distinguish the TB group and CR10 group. KEGG analysis results revealed that the differentially altered metabolites in duck plasma from the CR5 and TB groups were mainly associated with ovarian steroidogenesis, biosynthesis of unsaturated fatty acids, and phenylalanine metabolism. Conclusion: In this study, the production performance, blood indexes, number of metabolites and PCA were compared to determine effect of the caging stress stage on ducks. We inferred from the experimental results that caging-stressed ducks were in the sensitive phase in the first 5 days after caging, caging for approximately 10 days was an important transition phase, and then the duck continually adapted.

This study was attempted to identify the current status of education of gerontological nursing at nursing colleges across the country and to check whether 19 senior nursing competencies suggested by the American Association of Nursing Colleges are reflected in the courses. The subjects of this study were 198 nursing education institutions accredited by KABONE, and each university's website, department homepage, university handbook, admission-related information, curriculum table, and syllabus were collected and analyzed through an internet search engine. The collected syllabus and the most recent curriculum table of the elderly nursing course were checked and analyzed using SPSS 23.0. The current status of gerontological nursing management was presented by calculating the frequency and percentage, and the educational contents presented in the syllabus were analyzed based on 19 geriatric nursing competencies presented by AACN. 185 institutions (93.43%) operated the geriatric nursing subjects, 98 institutions (49.49%) offered theory subject, and 84 institutions (42.42%) offered both theory and practice. In the case of compulsory majors, 52.92% had the most, 27.84% for the first semester of the 4th year, and 53.54% for 2 credits. As a result of analyzing the lesson plan, communication-related educational competency was included in 40% of cases. As AACN gerontological nursing competency 'effective information provision ability for the elderly', 'ethical and non-coercive decision-making', 'care without restraint', 'safe and effective transition across levels of care' was not included in the education content. In conclusion, gerontological nursing education has been focused on disease, and effective information provision capabilities including communication with the elderly need to be reflected.

After industrialization in the past, the automobile industry has continued to grow centered on internal combustion engines, but is facing a major change with the recent 4th industrial revolution. Most companies are preparing for the transition to electric vehicles and autonomous driving. Therefore, in this study, topic modeling was performed based on LDA algorithm by collecting 4,002 domestic papers and 68,372 overseas papers that contain keywords related to CASE (Connectivity, Autonomous, Sharing, Electrification), which represent future automobile trends. As a result of the analysis, it was found that domestic research mainly focuses on macroscopic aspects such as traffic infrastructure, urban traffic efficiency, and traffic policy. Through this, the government's technical support for MaaS (Mobility-as-a-Service) is required in the domestic shared car sector, and the need for data opening by means of transportation was presented. It is judged that these analysis results can be used as basic data for the future automobile industry.
