Objectives: Despite its advantages, it is not yet common practice in Korea for researchers to investigate disease associations using spatio-temporal analyses. In this study, we aimed to review health-related epidemiological research using spatio-temporal analyses and to observe methodological trends. Methods: Health-related studies that applied spatial or spatio-temporal methods were identified using 2 international databases (PubMed and Embase) and 4 Korean academic databases (KoreaMed, NDSL, DBpia, and RISS). Two reviewers extracted data to review the included studies. A search for relevant keywords yielded 5919 studies. Results: Of the studies that were initially found, 150 were ultimately included based on the eligibility criteria. In terms of the research topic, 5 categories with 11 subcategories were identified: chronic diseases (n=31, 20.7%), infectious diseases (n=27, 18.0%), health-related topics (including service utilization, equity, and behavior) (n=47, 31.3%), mental health (n=15, 10.0%), and cancer (n=7, 4.7%). Compared to the period between 2000 and 2010, more studies published between 2011 and 2020 were found to use 2 or more spatial analysis techniques (35.6% of included studies), and the number of studies on mapping increased 6-fold. Conclusions: Further spatio-temporal analysis-related studies with point data are needed to provide insights and evidence to support policy decision-making for the prevention and control of infectious and chronic diseases using advances in spatial techniques.

Crowdfunding is a novel method for funding from many individuals using web based platform often in return for products or equity. It allows individual entrepreneurs to create diverse products and services. This thesis elaborates a theoretical foundation for identifying the factors that must have motivated the funders in sponsoring crowdfunding projects. Based on the motivation theory, the proposed research model is constructed with intrinsic and extrinsic motivations from relevant literatures. We also examined how different crowdfunding modes ('Keeping It All' and 'All or Nothing') moderate the proposed research model. Based on the survey from various crowdfunding service providers in Korea, this empirical study found that continuous participation in crowdfunding is positively correlated with factors such as enjoyment, familiarity, agency credibility and reward, while peer-influence shows negative correlation. Furthermore, moderating effects of funding modes significantly affect continuous participation. These empirical results contribute insights on the emerging phenomenon of crowdfunding from funders' perspectives and shed lights more on the ways that the actions of platform providers may affect their ability to receive entrepreneurial financing.

Main airports in the Intra-Asian market have faced competition not only to attract China-bound transshipment cargoes but also to be hub airport in same region. In spite of such a importance, the previous research has been short of evaluation of airport competitiveness. Implication of the previous research has mainly been focused on evaluation of airport critical factor service qualify and efficiency. The aim of this paper is to present critical points that affect airport competitiveness using an algorithm based on reversed fuzzy evaluation and senario method. The results of senario analysis and reversed fuzzy evaluation shows that Incheon international airport needs to enhance service level of 7% as a result of senario analysis and service level of 5% and brand equity level of 10% at the same time as a result of reversed fuzzy evaluation analysis, to ensure competitiveness in same region.

As popultations expand and economies develop, increasing competition for limited available water resources is occurring among many water users. This has brought greater attention to water allocation with legal and institutional constraints. This paper develops a optimal water allocation methodology to basinwide water resources allocation, which ensures that scare water resources are allocated among competing water users. The methodology need to be based on optimization technique to allocate water resources due to an extended scaled of river basin. The recommended model is developed to accomplish economic efficiency, equity and sustainability objectives. The appropriate case study is tested with various existing water right system allocation model and the recommended model. The result shows the applicability of model to the complex hydrologic system with legal and institutional constraints.

The purpose of this study was to examine the effects of perceived fit and brand transfer on extension evaluation in luxury fashion brands. The instrument for this research was a self-administered questionnaire based on a previously developed scale. The variables addressed in this scale included perceived fit, brand value for both parent brand (clothing) and extension brand (home line), extension brand association, and purchase intention of the product in extension brands. The participants in this research comprised of 215 female consumers between the ages of 19 and 51 demographically distributed nationwide. Data were analyzed by descriptive statistics, paired t-test, factor analysis, and regression analysis via SPSS 12.0. Findings showed that brand value consisted of two factors: cognitive and hedonic value in luxury fashion brands. Parent brand value was significantly related to perceived fit with a positive effect on brand association and hedonic value in extension brands. With respect to brand transfer, cognitive value of the parent brand increased the extension brand's cognitive value, while hedonic value of the parent brand increased the extension brand's hedonic value. In addition, purchase intention of the product in the extension brands was determined by the perceived fit and hedonic value of extension brands. This study also discusses the managerial implications for marketers in developing effective luxury brand extensions into new product categories, which leads to a synergy effect in building brand equity in the luxury fashion market.

This study examines the factors affecting Korean firms' adoption of maternity protection practices. From a neo-institutional perspective, we argue that firms adopt institutionally legitimized practices mainly for their legitimacy concern rather than technical efficiency. Analysis of data from Establishment panel survey reveals that firms which belong to public sector, has received foreign investment, bench-mark leading firms, or have HR department are more actively adopting maternity protection practices and are showing lower level of decoupling between model and reality. These results imply that legitimacy concern matters among Korean firms in terms of adopting maternity protection practices. We propose that it is important for government agencies to take institutional factors into account when they try to promote maternity protection policy among firms in dealing with the problems of low fertility and gender equity.

The relationship of information flow and market price formation are central to the basic tenets of financial economics. Whereas information is usually treated as being either public or private(monopolistic), most empirical studies focus on the price effects of public announcements. More recent research has centered more on the role of private information, such as insider trading, in efficient pricing and whether such trading increases investor welfare. Typically, 'insider trading' refers to an officer that trades in his/her company's shares. Insider trading, however, also refers to anyone who generates private, albeit costly, information concerning a stock's fundamental value. Normally, such insider activity is more difficult to ascertain. One way in which negative information is revealed is through short-selling activity, especially the monthly short-interest positions reported by the national stock exchanges. Diamond and Verrecchia(1987) provide a theoretical paradigm that predicts a negative price adjustment upon announcement of n company's monthly short interest, if the short interest displays an unusual increase and is correlated with negative information that is not yet public. Empirical studies of the short-run, negative price effect predicted by Diamond and Verrecchia find mixed results. One explanation is that the time period studied is too short for the market to absorb the informational content of these announcements. One reason is that these announcements are an ambiguous signal that requires more individuals and time to collect and act on the same information before full revelation occurs or before the implicit information becomes publicly known. This 'long delayed reaction' also serves as a motivation for related research on the wealth effect of mergers, share repurchases, and initial equity offerings in which long-run performance differs from the initial, short-run reaction to such announcements or offerings.

This paper examined the roles of academic libraries in open access journal publishing in terms of monetary supports for publication. As a result, many academic libraries have participated in the cooperative programs such as COPE(Compact for Open-Access Publishing Equity) and $SCOAP^3$(The Sponsoring Consortium for Open Access Publishing in Particle Physics) for authors to publish their research in open access journals. Also, 13 academic libraries in North America have set up the campus-based open access author funds individually. Most of academic libraries in participating COPE did not fund for research that have been published in the hybrid open access journals. In addition to publication funds, academic libraries provided authors or scholarly societies with such services as copyright negotiation, technological supports of the publication process, and the dissemination of open access publications.
