In this paper a numerical method is presented to solve singularly perturbed two points boundary value problems for second order ordinary differential equations consisting a discontinuous source term. First, in this method, an asymptotic expansion approximation of the solution of the boundary value problem is constructed using the basic ideas of a well known perturbation method WKB. Then some initial value problems and terminal value problems are constructed such that their solutions are the terms of this asymptotic expansion. These initial value problems are happened to be singularly perturbed problems and therefore fitted mesh method (Shishkin mesh) are used to solve these problems. Necessary error estimates are derived and examples provided to illustrate the method.

The purpose of this study is to develop an evaluation index for evaluating the economic value of libraries. To this end, a preliminary evaluation index was derived from analyzing a total of approximately 60 domestic and foreign papers that examined the value of libraries. Based on the derived preliminary evaluation index, 11 experts were selected and the final evaluation index was developed by conducting the Delphi survey for 3 times. The final evaluation index consists of four evaluation areas, such as the economic value of the public library, economic revitalization, manpower development and job creation, and the improved investment value, seven evaluation items, and 22 evaluation indices. In the future, it will be necessary to conduct research to measure the economic value of public libraries.

Purpose - This paper's purpose is to investigate how foreign ownership and innovation affect firm value. Design/methodology - Firm innovation is defined as operational efficiency, which is calculated by adopting data envelopment analysis (DEA). Additionally, R&D intensity is included as a measure of innovation in the analysis. We used firm-level data from manufacturing companies in Korea. The sample comprised 3,753 firm-year observations for every year in the period 2003-2017. Findings - We found that foreign ownership and innovation are positively related to firm value (Tobin's Q). Foreign ownership moderates innovation's contribution to firm value, implying that foreign ownership may enhance the value relevance of firm innovation. In addition, we found that firm innovation partially mediates the relationship between foreign ownership and firm value. Originality/value - This highlights the important role of foreign investors' monitoring; wherein foreign investors enhance firm value by facilitating firm innovation. Our results suggest that foreign ownership can be crucial for innovation and may serve to address weak ownership structures.

Due to the growing importance of ESG management, various studies have been conducted to explore the relationship between ESG performance and corporate value. The purpose of this study is to investigate how a company's ESG performance impacts its corporate value. The research findings indicate that there is difficulty in explaining the relationship between ESG performance of Korean IT companies and firm value in a straightforward manner. However, the results demonstrate that companies with higher profitability, higher foreign ownership, and higher R&D expenditure tend to have a positive impact of ESG ratings on corporate value. Based on these results, we can infer that Korean IT companies can enhance their corporate value by increasing R&D investments to develop innovative products that improve profitability. Additionally, attracting higher foreign investments can also positively influence ESG performance and subsequently increase corporate value. Acknowledging these factors can help companies realize the significance of ESG performance in elevating their overall corporate value.

This study aims to examine the moderating effects of environmental friendly attitudes between perceived value and loyalty in ecotourists. A total of 210 valid questionnaires were collected from visitors to Saemangeum and Sihwaho during 7 days. The functional value, social value, and emotional value were identified as dimensions of perceived value from factor analysis. Results from regression analysis revealed that emotional value and social value positively influenced loyalty. Moreover, environmental friendly attitudes were found to moderate the relationship between loyalty and emotional and social values. The findings suggest that policy makers and practitioners consider environmental friendly attitude and perceived values in making ecotourism programs to sustain ecotourism destinations.

In this study, we assessed college students' consumption values with regard to a seaweed functional food, and compared differences between the respondents' purchasing intentions and their educational levels. A self-administered questionnaire was designed and distributed to college students in Daegu/Kyungbook province. A total of 288 questionnaires were collected, and the total response rate was 96.0%. The results demonstrated that purchasing intention influenced all five consumption values. The high purchasing intention (HPI) group evidenced greater functional value, social value, emotional value, conditional value, and epistemic value than was observed in the low purchasing intention (LPI) group. However, individuals' educational levels, as related to food, influenced only the functional value and epistemic value. These results demonstrate that college students' consumption value in terms of seaweed functional foods is affected by purchasing intentions and educational experience.

Purpose - Many variables are needed for brand loyalty such as brand attitude, brand attachment, brand love and brand commitment. Thus, we should manage these all variables successfully for strong and differentiated brand equity. This study aims to identify the process of how the brand value propositions affect the brand attitude and brand attachment. This study specially conceptualizes that not only utilitarian value and hedonic value influence the brand attitude but also hedonic value influences the brand attachment. This study focuses on the moderating role of consumer involvement such as cognitive involvement and affective involvement in the causal relationships among brand value propositions, brand attitude, and brand attachment. Research design, data, and methodology - The five hypotheses were proposed and tested in this study. Three hypotheses were about the relationship among the brand value propositions(utilitarian value and hedonic value), brand attitude, and brand attachment. The other two hypotheses were about the moderating effect on consumer involvement in the causal relationships among brand value propositions, brand attitude, and brand attachment. Research data were collected from the students of universities located in Daejeon-Si and Chungchungnam-Do. For the purpose of test the hypotheses empirically, the 208 responses were used. We utilized SPSS18.0 for statistical analysis such as reliability test, factor analysis, and regression analysis. Results - The results show that the utilitarian value and hedonic value have influence on the brand attitude positively. The results also show that the hedonic value has influence on the brand attachment positively. We found that there is a moderating effect on the cognitive involvement in the relationship between the utilitarian value and the brand attitude. However, there is no moderating effect on the affective involvement in the relationship between the hedonic value and brand attachment. In Summary, 4 of 5 hypotheses in this study were supported and 1 hypothesis was not supported. We should identify the reason why the hypothesis 5, the moderating effect of the affective involvement in the relationship between the hedonic value and brand attachment, was rejected in this empirical analysis. Conclusions - Both the utilitarian value and the hedonic value that propose a brand are important for brand attitude. Specially, the hedonic value is important for brand attachment. Companies should provide the consumers with both the utilitarian value and the hedonic value in a balanced way for their favorable brand attitude and strong brand attachment. In the retail industry, the balance between the utilitarian value and the hedonic value is important in that there are many product brands and store brands providing consumers with various benefit and values. Also, there are possibilities that the causal relationships among brand value propositions, brand attitude and brand attachment are moderated by consumer involvement such as cognitive involvement and affective involvement. Companies should understand and consider consumer involvement for their efficient and effective brand management decision making.

This aim of this study is to support the value criteria that citizen evaluate themselves it when they found modern heritages in their town. To understand the changing of value criteria for the cultural heritage, we have to begin from early 20 century that were, however, diversified after 80's. As a result, early they evaluated with the architectural and aesthetic value mainly, after they evaluated with the social-cultural value and academical value, and nowadays they try to include the economical value and educational value. So this study rearranged and divided that value with the preservation and using value. The preservation value include the historical value, aesthetic value, social-cultural value and academical value, and the using value include the economical value and educational value. The criteria, however, don't have the equal importance, This study try to redefine relative importance score with paired comparison. As a result, Historical value is proved that most important criteria, but aesthetic value got the score lower than social-cultural value, and similar with academical values. And in using values, economical value and educational value got the low score. It means that if some researcher insist about the importance of economical value, it should evaluate lower than preservation values. This study insist that we have to include diversified values and that values have relatives score. Actually, now we mostly evaluate with the architecture and aesthetic values about modern heritage, so we are losing a lot of modern heritage. If we include the diversified values, social-cultural, academical and educational value, we can conserve our important modern heritage and revitalizing town with tourism of historical heritage.
