Social medicine is recognized as one of medical specialties in many countries. However, social medicine has never been formally introduced to Korea, presumably because the term and its principles were not accepted for some years in the past in American medicine, which has strongly influenced Korean medicine. This paper describes the origins and evolution of social medicine and briefly discusses contemporary social medicine in Korea. Social medicine was initiated in France and Germany in 1848. Since then, it has expanded globally and developed in diverse ways. Included in core principles of social medicine is that social and economic conditions have important effects on health and disease, and that these relationships must be subjected to scientific investigation. The term 'social medicine' is rarely used in Korea, but many of its subject matters are incorporated into preventive medicine which, besides prevention, deals with population health that is inescapably social. However, the Korean preventive medicine directs little attention to the basic concepts and principles of social medicine, upon which systematic development of social medicine can be based. Thus, it is necessary to supplement the social medicine contents of preventive medicine through formalizing the linkages between the two fields. One way of doing so would be to change the title of 'preventive medicine' course in medical colleges to 'preventive and social medicine,' as in many other countries, and to adjust the course contents accordingly.

There has been increasing number of patients with asthma, rhinitis, and conjunctivitis due to the atmospheric pollution and global warming. In this study, we investigated daily observed number of pollens to establish a standardized method for the impact analysis of the climate changes on the number of daily pollens in Korea. Daily observed allergenic pollens of trees, weeds, and pine were analyzed during the period of 1998 to 2010 (except 2006) in Seoul, Busan, Daegu, Gwangju, Gangneung, and Jeju. They increased in large cities including Seoul during the last 12 years and the long-term trend may continue in the future. Daily concentration or amount of pollens was highly correlated with weather variables. Positive correlation was found between air temperature and the pollens although different relationships existed for different locations. Chill days were utilized to estimate the length of the flowering or pollen period. The pollen period of trees was shorter in the field when the winter temperature was low. This approach may be utilized to determine the quantitative change in length of the pollen season in the future.

The purpose of this study was to understand the process and investigate basic theory of fatigue experience of shift work nurses. The present study adopted grounded theory methodology on fatigue of shift work nurses. The participants for this study were 15 shift work nurses who were in the age of 25 to 35, the clinical experience of 2 to 14 years and the work department of ICU. ER. ward and delivery room. The data were collected from 2000 to 2003 by using interviews and observations. The contents of the interviews were tape-recorded and were drawn through repeated method. And then were analyzed into the concept, subcategories, and categories with the open coding process and axial coding was done to identify the relationships of the concepts and categories according to the paradigm models. The core category generated, which was a central phenomena of the exhaustion process. The causal condition is change events. The central condition of exhaustion were sorted as physical discomfort, decreasing vigor, psychological instability, feeling of sleeping desire, changing face impression and being heavy body. The intervening condition were discovered as social$\cdot$ psychology$\cdot$physical resist and positive$\cdot$negative interaction strategies. The consequences of the fatigue process is the short term exhaustion relief and long term residual exhaustion. The fatigue process of this study was 'break through exhaustion' of change event-exhaustion-resist-resolve intervention-adaptation. This study offers better understanding on fatigue process of shift work nurses and may facilitate more appropriate interventive strategies to support, information and knowledges according to fatigue process.

Firms can make scale of economy and scope of economy by internalizing and using new advanced technology and knowledge from technology cooperation network, decrease risk and cost with partner firm of technology cooperation network, and increase market advantage of product & strengthen firms' position in the market. Due to the advantages of technology cooperation network, the related studies have focused on the positive effect of technology cooperation network. However, the related studies investigating the relationship between technology cooperation network and firm performance have only examined the role of technology cooperation network. Safeguarding mechanism, relationship learning, and relationship performance are categorized into the process of technology cooperation network, and this categorization is applied as resources, capability, and performance by resource based view. The empirical results are reported as belows. First, relationship specific investment and relationship capital positively affect on relationship learning as capability. Second, information sharing, common information understanding, and relationship specific memory development positively affect on long-term orientation, but information sharing has no impact on efficiency and effectiveness. Third, relationship specific investment positively affects on relationship capital and efficiency and effectiveness have positive effects on long-term orientation. Applying technology cooperation network in asymmetric technology dependency with resource based theory, this study suggested the importance of both safeguarding and relationship learning by investigating the relationship among safeguarding, relationship learning, and relationship performance. And it is worthy that this study investigated how firms' behavior change affects relationship performance in the relationship of technology cooperation partner.

The purpose of this study was to investigate a reliability and validity of the Korean version for measuring tool the job embeddedness of dental hygienists. The survey was modified and revised to fit into Korean culture. A survey was conducted with 274 dental hygienists in dental clinics. The data was used for the analysis of the study, using PASW Statistics 18.0 and IBM SPSS AMOS 7.0. The factor analysis showed that the job embeddedness of the dental hygienists was composed of three elements, namely 'organization fit', 'job connectivity', and 'personnel relationships'. The validity of the model examined by a confirmatory factor analysis satisfied most of the relevant requirements. All of the factors had the conceptual reliability and variant extracted index above the minimum requirements, ensuring reliability and concentrated validity. The Cronbach's alpha shows a good reliability. In conclusion, it was proven that dental hygienist's job embeddedness measurement tool has high validity and reliability. Further, this study could be used to improve dental hygienist's long term working, and the growth stage of dental clinic.

China holding the world largest shale resources, has been trying to develop their domestic shale gas fields mainly with its NOCs. Chinese shale industry looks likely to have high potential to grow in the future, considering the eager support of Chinese government and the rapid development of relevant technologies by NOCs. However, there are opposite opinions as well that Chinese shale gas could not play a positive short-term results because of the complexity of structural geology, inadequacy of water resources and related infrastructure. Recently, Korean companies began to be interseted in Chinese shale gas industry, because of the special relationships with Korean industries in terms of geographic proximity and better opportunities due to the early phase of shale gas business in China. In this study, it was tried to help those companies looking out of future Chinese shale gas industry that surveying current status and problems of Chinese shale gas industry and relevant industries and investigating some trials and policies driven by China government. As a result, the various and long-term problems in Chinese shale development were reviewed and the active supports and polices of Chinese government, NOC's trials for establishments of their independent technologies and the cooperation with foreign companies or M&As were also investigated.

The purpose of this study is to investigate the relationships between physical factors, economic factors, and cultural factors of tourism gentrification (TG) in urban areas. Based on the results of an empirical analysis, we provide the basic theory and practical implications of the relationship between tourism phenomena and city image. This study used a questionnaire for residents of the Jeju area. From September 1, 2018, to October 3, 2018, the survey was conducted in Nuemori Street, Yeongdong Street, Gucheong Eup, and Moon Town. Thus, we use 479 samples for analysis out of 500 samples obtained. This study produced two important results. First, the physical, economic, and cultural factors of tourism gentrification have significant effects on cognitive image and emotional image. Second, economic factors have statistical significance in cognitive image and emotional image. These results and implications can be useful for practical implications of the theoretical implications of tourism gentrification and regional specialization promotion policies. In addition, from the economic point of view, what should be considered is that development-centered area development can have a negative impact on urban image. Despite these research results, there are limitations in the research, such as cross-sectional studies and short-term studies, and we look forward to a longitudinal study in the future from a long-term perspective.

We have examined dynamic relationships among water-efficiency, economic growth, electricity generation, and $CO_2$ emissions in Korea using various time-series analysis methods for 1990-2014. While previous studies have been limited to economic growth, $CO_2$ emissions, and electricity generation, this study contributed to explain the relationship between existing variables and water-efficiency. We find that the four variables reach a balanced state in the long run through short-term adjustment, $CO_2$ emissions and economic growth are responsible for water efficiency, and that $CO_2$ emissions, economic growth and water efficiency are the causes of electricity generation. The long-term impact coefficient estimates on water-efficiency show that the increase in electricity generation and the decrease in $CO_2$ emissions increase water-efficiency. Although economic growth has increased water-efficiency, moreover, we have identified an inverted U-shaped relationship between economic growth and water-efficiency, which suggests that economic growth above a certain level reduces the rate of increase in water-efficiency.

In South Korea nowadays, Among the married immigrant women in Korea, the proportion of long-term residents living in Korea for more than 10 years is increasing continuously(48%), while the proportion of short-term residents who are under 5 years is decreasing(16%). However, Korean language education and related research in the Marriage and Immigration Women's Center are still focused on the initial immigrants. Therefore, we should classify married immigrant women according to their stay time in Korea, so that Korean language education and teaching materials need to be more diversified. This study focuses on married immigrant women with intermediate and advanced Korean proficiency and chooses a catalogue of Chinese characters idioms to explore the possibility and educational value of using Chinese characters Idioms in Korean education. According to the research results, Chinese characters idiom education can help married immigrant women in Korean language learning and information acquisition, interpersonal relationships and life attitudes, cultural understanding and social adaptation, child rearing and learning guidance. This is the important part of Korean language education that needs to be guided by married immigrant women. Based on this, 130 Chinese characters idioms in Korean language education and textbook development centered on married immigrant women were selected and catalogue edited in four stages. It is hoped that the results of this study will serve as a reference for Korean language education research and textbook development for married immigrant women in the future.

The purpose of this study is to review person-centered care models and the scientific evidence for the impact of person-centered care in U.S. nursing homes, and to analyze the applicability of person-centered care for Korean long-term care system. The most commonly recognized person-centered care models were Eden Alternative, Green House, and Wellspring model. The core components of the three models were autonomy, close relationships, homelike environment, and staff empowerment. Thirty eight empirical studies including 10 model testing studies and 28 studies to examine the impact of person-centered care interventions indicated generally positive outcomes in terms of residents, family, and staff/organization level. The authors analyzed the current situation in the Korean long-term care system with respect to the specific core constructs of person-centered care, and proposed applicable models and practical suggestions in consideration of Korean context. Lastly, future considerations regarding policy and research were discussed.
