This study is based on Degree of Recognition and AHP surveys for experts, this study investigates changes in the demand of seafarers in response to changes in the shipping industry environment in which Maritime Autonomous Surface Ships(MASS) emerge according to the application of the fourth industrial revolution technology to ships, and it looks into changes in seafarers' skills. It also analyzes and proposes a plan for cultivating seafarers accordingly. As a result of Degree of Recognition and AHP analysis, it is analyzed that a new training system is required because the current training and education system may cover the job competencies of emergency response, caution and danger navigation, general sailing, cargo handling, seaworthiness maintenance, emergency response, and ship maintenance and management, but jobs such as remote control, monitoring diagnosis, device management capability, and big data analysis require competency for unmanned and shore based control.By evaluating the importance of change factors in the duties of seafarers in Maritime Autonomous Surface Ships, this study provides information on seafarers educational institutions response strategies for nurturing seafarers and prioritization of resource allocation, etc. The importance of factors was compared and evaluated to suggest changes in the duties of seafarers and methods of nurturing seafarers according to the introduction of Maritime Autonomous Surface Ships.It is expected that this study is meaningful as it systematically derived the duties and competency factors of seafarers of Maritime Autonomous Surface Ships from a practical point of view and analyzed the perception level of each relevant expert to diagnose expert-level responses to the introduction of Maritime Autonomous Surface Ships.

In previous Cost-of-Illness (COI) studies, the economic impact of lost leisure time of patients has been mostly underexplored. Furthermore, few studies have focused on chronic or severe diseases, thereby inadequately addressing the segment of self-care patients who do not fall into the categories of inpatients or outpatients. In the present study, we used a comprehensive approach to calculate the annual cost of leisure loss, incorporating factors such as employment status, self-care options, and total period of leisure activity disruption. This required analyzing data from various sources, including health and labor statistics, and applying methods to accurately assess the leisure time lost due to food poisoning. The findings showed that the annual cost of leisure loss for South Korean patients with food poisoning is significant, amounting to approximately 784.5 billion KRW (702.8 million USD, USD/KRW : 1128.34). This study revealed that overlooking self-care patients and not accounting for the affected time in addition to treatment time and employment status significantly underestimated these costs. This study highlights the importance of considering a wider range of factors, including self-care, employment status, as well as the entire affected period, in assessing the societal impact of diseases such as food poisoning. These findings provide valuable insights for policymakers and healthcare professionals to understand the broader economic implications of illness and allocate healthcare resources more effectively.

Recreation forests are in the spotlight as the place for personality development, mind and body comfort, companionship, and environment education in forests and valleys. Visitors to recreation forests have been on the increase along with booming in recreation forest building since 1988. Recreation forests are being categorized according to some features such as regional and environmental condition. Recreation forests, however, have not met the expectations of some visitors who want to take a rest with calmness due to the influence of the 5-day-work-week system, increasing interest in rest, leisure, and well-being, and users converge during weekends, summer, and the tourist season. In order to improve visitors' satisfaction efficiently, this study surveyed the level of satisfaction in each cluster based on the precedent study which had classified 85 national or public recreation forests in Korea into clusters. Questionnaires were distributed properly to each cluster and, of the 1,132 questionnaires collected, 1,015 were valid and used for analysis. Reliability of questionnaires and statistical validity of the model were verified. As a result, there are meaningful differences in the ranking of independent variables which affect the level of satisfaction according to clusters. Variables in rest and fatigue recovery have the strongest influence on the level of satisfaction in the clusters of potential factor, internal activation factor, and mixed potential capacity factor. In the use performance and visiting condition factor cluster, appropriateness of visit cost is most influential and, in the education cluster, connectivity with tourist attractions around it is most affective. These results can provide priority in services and maintenance of recreation forests for improving the level of satisfaction and differentiate the distribution of resources according to clusters.

The purpose of this study is to provide preliminary data for political measures to minimize the variations by understanding the regional variations and trends of hospital services for heart diseases, and analyzing the factors that could occur any variations. The various data collected from nation-wide inpatient services conducted separately by small region show that there have been some differences in income level, supply of medical resources, standardized rate of hospitalization by sex and age, health level in the residence, and the length of stay per head. Then it indicated that the number of special medical equipment per 10,000 people and the rate of vigorous physical activity have the highest influence over the regional variations in using hospital services. On the other hand, the number of sick-beds per 10,000 people, the number of special medical equipment, and the present smoking rate have significant degree of influence on the length of stay per head. Thus, it is imperative for the authorities to set aside health promoting policies and to distribute the medical resources equitably throughout the country and to enhance the accessibility of local residents to the health care services.

A balanced regional development has a great meaning of economics in the fact that the People could enjoy the equal level of lift everywhere in the country by reducing the income disparity and economic productivity between regions, however as the our country was given Preponderance of economical power and development to the metropolitan area centering around Seoul due to a factor of politics, social structure as well as a national economic policy centering around a rapid economic growth, the unbalanced regional growth gave rise to great hindrance to a national development. Especially, the unbalanced 9rowth between regions gave rise to a sense of alienation to a citizen in a special region as well as a distortion of an effective resources distribution. therefore it was deepen a social discord to hinder the unity of the people due to always coming to involve social ,political affairs. The major contents of this study is to clarify relations between the economic growth and the balanced regional development to form a concept of a national development, and this thesis made disparities in population and convenient facilities between regions through change of convenient facilities of life, economic growth, and population between regions an analytic object to concrete the studies. Also, this thesis made a whole countw land an analytic object of spatial sphere. and it made a unit of ten years when the five-year economic development plan was achieved from the year 1962 to 2001 an otject of the time range of studies.

This study was conducted to identify and compare the needs of the integrated by local government, and to provide basic data for the provision of integrated care services. This is a secondary data analysis study using data from 10,299 elderly people living in 17 local governments who participated in the '2017 National Survey on the Aged People in Korea'. The difference in medical needs, daily living support needs, and social activity support needs were 2.4, 6.0, and 2.0 times higher in the highest regions than in the lowest regions. In addition, the size of the medical needs group, welfare needs group, and integrated care needs group varied by region. Through this study, it was confirmed that the level of integrated care needs varied by region. Therefore, in order to efficiently provide the services at the national level, it is necessary to accurately assess the needs of the aged in each local government, and accordingly, prioritize and identify available resources within the care service and appropriate allocation.

This study is an attempt to deduct environmental uncertainties facing next-generation convergence services, in four areas including customer, technology, service provider and regulation. We assess the level of residual uncertainty with regard to key environmental uncertainty factors, and conduct a scenario planning analysis. Based on the results of this analysis, we provide suggestions on market entry strategy for providers of this next-generation convergence service. The strategic assessment of six scenarios developed in this study, each with two levels of residual uncertainty (alternate futures and a range of futures) resulted in two key success factors (KSF), namely, customer demand trends and easing of advertising restrictions. Four types of strategic scenarios were then discerned, for each of which we present response capabilities that may be required of service providers, along with strategic suggestions. The results of this study are rich in implications for both policy-makers and regulators seeking ways to create and stimulate a convergence service market and prospective providers of next-generation convergence services, as they provide concrete tips related to market entry strategy, including efficient resource allocation, types of market entry and time-frames for entry.

산업화에 따른 온실가스 배출량 증가는 심각한 기후변화의 요인으로 작용하여 우리나라를 포함한 전세계는 이에 대응하고자 노력하고 있다. 지구온난화 및 엘리뇨 현상 등으로 인하여 가뭄, 홍수, 한파, 혹서 등의 재해와 기상이변이 속출하고, 최근 우리나라의 경우 매년 가뭄이 발생하고 있어 이에 대한 대책이 시급한 실정이다. 이에 가뭄의 대처방안에 대한 관심이 증대 되었고, 가뭄을 정량적으로 하는 연구들과 기후변화에 따른 가뭄 취약성 평가에 대한 연구들이 진행 되었다. 가뭄의 취약성 평가는 기후변화에 따른 가뭄 저감을 위한 목적에 따라 평가목적, 평가방법, 필요한 정보, 과정의 설계 불확실성에 대한 고려 등이 달라진다. 취약성 평가의 목적은 크게 기후영향평가, 적응정책의 자원배분을 위한 취약부문 및 지역 파악, 적응정책 개발을 위한 적응 대안 분석으로 나눌 수 있다. 취약성 평가의 목적이 취약성 유발요인에 관한 정보를 제공하여 어디에 적응 대책에 필요하고 효과적일 수 있는지 파악하는데 도움을 주는 것이라면, 취약성 결정요인에 대한 분석을 명료하고 상세하게 수행하는 것이 중요하다. 본 연구에서는 기후변화에 따른 농업용수의 취약성 평가지표를 개발하기 위하여 국내 외 취약성 평가 지표를 분석, 국내 농업기상 및 농업용수 등 관련 자료(1981 ~ 2015)의 조사 현황을 고려하여 취약성 평가지표(강우량, 증발산량, 경지면적, 저수용량, 용수로 통수능력, 수요량, 하천평수위)를 제시하고 국내 농업기상 및 농업용수 등 관련 자료의 조사 현황을 고려하여 대상지구인 충북 진천 무수 관개지구에 취약성 지표를 적용하였다. 강우의 증가는 가뭄 취약성에 긍정적 영향을 나타냈고, 증발산량의 증가는 부정적인 영향을 나타냈다. 경지면적의 감소는 소비수량이 증가하므로 가뭄 취약성에 긍정적인 영향을 나타냈고, 저수 용량의 감소는 홍수조절능력의 저하로 인해 부정적인 영향을 끼치고, 하천 홍수위의 변화는 가뭄에 영향을 미치는 요소 중의 하나로 홍수위가 높아지면 가뭄에 부정적인 영향을 나타냈다. 가뭄 취약성 지표들을 각각의 가중치를 합산한 결과, 1981년~2015(5년 분할) 무수지구의 가뭄 취약성 평가는 분석을 시작한 1981년부터 2015년 까지 안전과 우려가 반복 되는 것으로 나타났다. 연구대상지구의 농업기상 및 관련 자료들의 조사 기간이 길면 빈도별 신뢰성이 높아진다. 따라서 자료의 누적은 정확한 기후변화에 대한 이수 및 치수 취약성 평가 지표개발 및 평가 능력을 높여 줄 수 있을 것으로 판단된다.

This study aims to empirically measure K-pop fans' content and the extent of online activities. To achieve the purpose of the study, the researchers identify the statistically significant online activities that determine the intensity of fan attachment toward K-pop artists. Further, the research confirms the relative importance of various meaningful online activities. Consequently, we can develop the K-pop Online Activity Index (KOAI) model and apply it to this index model empirically for each respondent. We found that the model consists of five online activities of K-pop fans: whether joining the fan club or not, whether paying per view V live+ or not, whether watching VODs associated with artists or not, the degree of fan club writing, the degree of watching a lot on YouTube to improve the value of my artists. This study has practical significance in that it allows K-pop marketers to improve their marketing performance by providing content that will enable them to more efficiently and effectively allocate marketing resources to various online activities to get fan responses. It allows accumulating academic knowledge to understand the behavior in the field of online behavior for K-pop fans.
