Objectives : This study evaluated knowledge structure and its effect factor by analysis of co-author and keyword networks in Korea's preventive medicine sector. Methods : The data was extracted from 873 papers listed in the Journal of Preventive Medicine and Public Health, and was transformed into a co-author and keyword matrix where the existence of a 'link' was judged by impact factors calculated by the weight value of the role and rate of author participation. Research achievement was dependent upon the author's status and networking index, as analyzed by neighborhood degree, multidimensional scaling, correspondence analysis, and multiple regression. Results : Co-author networks developed as randomness network in the center of a few high-productivity researchers. In particular, closeness centrality was more developed than degree centrality. Also, power law distribution was discovered in impact factor and research productivity by college affiliation. In multiple regression, the effect of the author's role was significant in both the impact factor calculated by the participatory rate and the number of listed articles. However, the number of listed articles varied by sex. Conclusions : This study shows that the small world phenomenon exists in co-author and keyword networks in a journal, as in citation networks. However, the differentiation of knowledge structure in the field of preventive medicine was relatively restricted by specialization.

The study attempts to analyze the impact of firm's risk on capital structure in the context of seasonal and non-seasonal businesses. We use two independent variables namely credit risk and systematic risk and one dependent variable to explore this connection. Sugar sector is taken as seasonal while the textile sector as non-seasonal businesses. The panel data of twenty-five firms from each sector are taken ranging for the period of 2012 to 2019 which has been retrieved from their annual reports for empirical analysis of the study. The results reveal the negative impact of credit risk on capital structure in both types of businesses. Increasing (decreasing) one point of credit risk causes a decrease (increase) leverage ratio by 0.27 points for seasonal while increasing (decreasing) one point of credit risk causes to decrease (increase) leverage by 0.15 points for non-seasonal businesses. Furthermore, the study shows positive impact of systematic risk on leverage ratio in non-seasonal business and no impact in seasonal business. Any increase (decrease) in the systematic risk causes an incline (decline) leverage ratio by 2.68 units for non-seasonal businesses. The study provides a guideline to managers for risk management in businesses. The research focusses on theoretical as well as managerial and policy implications on risk management in businesses.

이 연구의 목적은 가나의 농촌지도사업과 농업기술의 국제협력시스템의 현황과 방향을 탐색하는 것이다. 향후 농촌지도사업의 역할은 지금까지 해 오던 것과는 매우 다를 것이다. 농업기술시스템의 촉진자로서의 농촌지도의 역할은 민간부분의 증가와 함께 증가될 것이다. 공공 농촌지도사업은 민간 부분에서는 농민들의 다양한 요구에 부응할 수 없기 때문에 계속적으로 그 중요성이 증가할 것이다. 향후 이러한 변화와 함께, 가나의 농촌지도시스템에서 내적인 개혁은 도전에 직면하게 될 것이다. 국제협력시스템은 외부의 이해당사자와 농촌지도사업의 파트너십을 형성하는데 중요한 역할을 할 것이다. 종자산업으로부터 나타난 혁신은 역동적이고 시스템적인 과정이었다. KAFECI는 그러한 변화가 2-3년안에 일어난다면 이러한 변화를 유연하게 받아들여야 한다. 기술이전과 전파의 도구나 틀은 다양한 사회경제적인 배경속에서 공동의 목적을 향해 도전하는 혁신적인 플렛폼으로서 발전되어져야 한다.

Two dominant phenomena in modern world; population ageing and digitalization, have led public sector organizations to heavily rely on B2C(Business-to-Consumer) mobile applications. Yet, fatal concerns and complaints have often been raised by the mobile application users, notably from social welfare sector. With the continual expansion of digital landscape as well as the growth of life expectancy, usage of mobile applications has become prevalent across the stakeholders involved in social welfare sector. 'Smart Long-Term Care (SLTC)', inter alia, is a primary example of such mobile applications, designed to support Long-Term Residential Care (LTRC) service. The main goal of SLTC is to serve more convenient and practical LTRC service for both caregivers and care receivers. To examine user satisfaction of SLTC mobile application, this study investigates existing challenges and means to improve user satisfaction. Hence, we conducted this study using two methods: in-depth interview and topic modeling. Interestingly, two research outcomes commonly indicated that 5 factors (stability, accessibility, usefulness, responsiveness, and ease of use) were found significant in affecting user satisfaction of SLTC. Our findings suggest that the aforementioned factors can be seen as potential causes of the genuinely low user satisfaction. Eventually, this work will be a stepping-stone to elevate the overall quality level of LTRC service along with the user satisfaction degree of SLTC mobile application.

Corporate social responsibility (CSR) is of increasing interest to both industry practitioners and academics because of increasing public awareness of environmental, economic and social sustainability. The last decade witnessed a large number of studies on the development of CSR principles and the implementation of CSR in various industries such as the mining industry, oil industry and food industry. However, there is limited number of CSR studies focusing on the construction industry. Considering the critical role the construction industry plays in achieving economic, social and environmental sustainability, it is imperative to extend the current CSR research to the construction sector. This paper provides a critical review of literature related to corporate social responsibility in construction context. A special focus is placed on the current practice adopted by the industry to be socially responsible. A research agenda is set up to tackle this critical issue.

Data plays an ever greater part in the tourism industry. While the platform-based sharing of open public data, private-sector intermediary platforms, and the use of social media to understand consumer trends are already well recognized, more potential for innovation exists in sharing private data among organizations in Smart Tourism Destinations. Research into the factors enabling and hindering coopetition in this kind of data sharing platforms is still in the nascent stage of development. Our case study of Sapporo, a major Japanese city endeavouring to create itself as a Smart Tourism Destination, sheds light on the initial approaches to involve organizations to such a data sharing agreement. Founding on seven interviews with ten participants of Sapporo Smart City project organization (SARD), we derived enablers and impediments that promote coopetition in data sharing as part of Smart Tourism Destination development. We also present practical recommendations and future research opportunities for such initiatives.
