  • Purpose - A lot of preceeding studies have focused on the pains that might be felt in spending money, that is an important role in getting psychological safety. Money and social resources can be all for consumers, and they are likely to form a substituting relationship with one another. Being motivated by the idea that spending money for others can come with joy if one's objective is accomplished by social support, this paper aimed to explore the mediating role of the perceived money importance and gratitude in the relationship between social support and pleasure in spending for other-gift. Research Design, Data, and Methodology - In this empirical study, the experimental group is expected to receive social support while the control group is composed of those who are usually indulged in reminiscences of their sweethearts. From the college students, 160 experiment participants were selected and 80 participants of them were assigned to control group as well as to experimental group respectively at random. Empirical study for each of the two groups was performed respectively by means of questionnaire survey. Experimental group data and control group data were combined together to be used for testing hypotheses. Linear structural equation model in Amos was used to verify the hypotheses, and Bootstrap was also used to examine whether there were the mediating roles of the perceived money importance and gratitude or not. Results - From the empirical study, following conclusions could be drawn: First, social support of others makes one perceive the importance of money less; Second, social support of others makes one perceive gratitude to others; Third, less perceived importance of money and gratitude to others can make one feel pleasure in spending for other-gift; and Fourth, less perceived importance of money and gratitude to others can partially mediate the effect of social support from others on the pleasure in spending for other-gift. Conclusions - The outcomes of this study might offer theoretic and managerial implications as follow: Even though many hitherto studies have asserted that spending money usually comes with pains, this study discovered that social support might reduce perceived the importance of money but make others feel gratitude and, thus, one would feel joy in spending money to buy gift for others, and made a contribution to the progress of the theory of pleasure in spending for other-gift. This paper also made contributions toward the development of emotion marketing theory by showing that the effect of social support on the pleasure in spending for other-gift could be partially mediated by the perceived the importance of money and gratitude to others. Based on the above conclusions, it may be affirmed that marketers should help consumers perceive the importance of money less, and help feel gratitude to others by pointing up the support of others to consumers in an attempt to accelerate spending for other-gift.

  • This study was conducted to build a structural equation model explaining factors that affect hemodialysis patients' quality of life to test the goodness of fit of the model and identify directly and indirectly significant paths. To accomplish this, 230 patients receiving hemodialysis registered at study hospitals in G Metropolitan City and M City were randomly selected, and 201 were used in the final analysis. Data were collected using a self reporting questionnaire from February 1 to March 31, 2014. SPSS WIN 18.0 was used for descriptive statistics and correlation analysis of the general characteristics and for reliability analysis of the research tools. In addition, AMOS 18.0 was used for confirmatory factor analysis of latent variables, to determine the goodness of fit of the hypothetic model, and hypotheses testing. The results of this study were as follows: the fit of the modified model was 41.32, GFI = .96, AGFI = .92, RMR = .04, NFI = .96, CFI = .91 and TLI = .95. Twelve out of the 22 research hypotheses that were improved and improved were statistically significant. The results indicated that hemodialysis patients' quality of life was influenced directly by self-efficacy, depression, and self-care behavior, and indirectly by sleep disturbance, stress, fatigue, and family support. These variables explained 58.6% of the variation in quality of life. Overall, these findings suggest that nursing interventions for hemodialysis patients require strategies for managing patient depression and for increasing self-efficacy and self-care behavior to improve quality of life.

  • In franchise business, exclusive sales territory (sometimes EST in table) protection is a very important issue from an economic, social and political point of view. It affects the growth and survival of both franchisor and franchisee and often raises issues of social and political conflicts. When franchisee is not familiar with related laws and regulations, franchisor has high chance to utilize it. Exclusive sales territory protection by the manufacturer and distributors (wholesalers or retailers) means sales area restriction by which only certain distributors have right to sell products or services. The distributor, who has been granted exclusive sales territories, can protect its own territory, whereas he may be prohibited from entering in other regions. Even though exclusive sales territory is a quite critical problem in franchise business, there is not much rigorous research about the reason, results, evaluation, and future direction based on empirical data. This paper tries to address this problem not only from logical and nomological validity, but from empirical validation. While we purse an empirical analysis, we take into account the difficulties of real data collection and statistical analysis techniques. We use a set of disclosure document data collected by Korea Fair Trade Commission, instead of conventional survey method which is usually criticized for its measurement error. Existing theories about exclusive sales territory can be summarized into two groups as shown in the table below. The first one is about the effectiveness of exclusive sales territory from both franchisor and franchisee point of view. In fact, output of exclusive sales territory can be positive for franchisors but negative for franchisees. Also, it can be positive in terms of sales but negative in terms of profit. Therefore, variables and viewpoints should be set properly. The other one is about the motive or reason why exclusive sales territory is protected. The reasons can be classified into four groups - industry characteristics, franchise systems characteristics, capability to maintain exclusive sales territory, and strategic decision. Within four groups of reasons, there are more specific variables and theories as below. Based on these theories, we develop nine hypotheses which are briefly shown in the last table below with the results. In order to validate the hypothesis, data is collected from government (FTC) homepage which is open source. The sample consists of 1,896 franchisors and it contains about three year operation data, from 2006 to 2008. Within the samples, 627 have exclusive sales territory protection policy and the one with exclusive sales territory policy is not evenly distributed over 19 representative industries. Additional data are also collected from another government agency homepage, like Statistics Korea. Also, we combine data from various secondary sources to create meaningful variables as shown in the table below. All variables are dichotomized by mean or median split if they are not inherently dichotomized by its definition, since each hypothesis is composed by multiple variables and there is no solid statistical technique to incorporate all these conditions to test the hypotheses. This paper uses a simple chi-square test because hypotheses and theories are built upon quite specific conditions such as industry type, economic condition, company history and various strategic purposes. It is almost impossible to find all those samples to satisfy them and it can't be manipulated in experimental settings. However, more advanced statistical techniques are very good on clean data without exogenous variables, but not good with real complex data. The chi-square test is applied in a way that samples are grouped into four with two criteria, whether they use exclusive sales territory protection or not, and whether they satisfy conditions of each hypothesis. So the proportion of sample franchisors which satisfy conditions and protect exclusive sales territory, does significantly exceed the proportion of samples that satisfy condition and do not protect. In fact, chi-square test is equivalent with the Poisson regression which allows more flexible application. As results, only three hypotheses are accepted. When attitude toward the risk is high so loyalty fee is determined according to sales performance, EST protection makes poor results as expected. And when franchisor protects EST in order to recruit franchisee easily, EST protection makes better results. Also, when EST protection is to improve the efficiency of franchise system as a whole, it shows better performances. High efficiency is achieved as EST prohibits the free riding of franchisee who exploits other's marketing efforts, and it encourages proper investments and distributes franchisee into multiple regions evenly. Other hypotheses are not supported in the results of significance testing. Exclusive sales territory should be protected from proper motives and administered for mutual benefits. Legal restrictions driven by the government agency like FTC could be misused and cause mis-understandings. So there need more careful monitoring on real practices and more rigorous studies by both academicians and practitioners.

  • Although an association of Kawasaki disease (KD) with infectious agents has been suggested, none have been proven to cause KD. In this case study, we present a case of KD with concurrent onset of influenza and Mycoplasma pneumoniae (MP) infections. A 27-month-old boy presented with prolonged fever, cough, and rhinorrhea. During the initial testing, influenza A infection was identified, and he was treated with oseltamivir. Despite the antiviral therapy, the fever persisted, and he had cervical lymph node enlargement, bilateral conjunctival injection, fissured red lips, strawberry tongue, and erythematous skin lesions on the Bacillus Calmette-$Gu{\acute{e}}rin$ vaccination site. Thus, the patient was diagnosed with KD and was treated with intravenous immunoglobulin (IVIG). The result of the initial antimycoplasma immunoglobulin M (IgM) antibody testing and was positive, and an increased IgM titer from baseline was found in a repeat test. We reviewed the hypotheses on pathogens known to be associated with KD and the etiology of KD. Based on our findings, we suspect that symptoms of KD and coronary artery lesions can occur from various infections besides those caused by Mycoplasma species and influenza viruses.

  • Purpose - This study investigated the effects of consumers' selection criteria for environment-friendly agricultural products on purchase intention and the effects of consumers' attitudes and the reliability of environment-friendly agricultural products on purchase intention by using the theory of planned behavior. Subjective norms of variables of behavioral intention, attitudes toward behavior and control of the behavior were used to create selection criteria, consumers' attitudes and reliability of environment-friendly agricultural products. The study investigated the effects of consumers' selection criteria, attitudes, and reliability of environment-friendly agricultural products on purchase intention constructing models and hypotheses of mediation and moderation between selection criteria for agricultural products and purchase intention by consumers' attitudes and reliability. Research design, data, and methodology - The findings were as follows: first, consumers' selection criteria for environment-friendly agricultural products had a significantly affirmative influence upon purchase intention. Health was the most important factor of selection criteria convenience was more important than quality and familiarity was next. Consumers' attitudes and trust had a significant influence on purchase intention. Second, testing showed that consumers' attitude and trust partially mediated selection criteria: sub-factors and purchase intention were important in selection criteria. Third, testing showed that consumers' attitude and trust had a significant moderation effect between selection criteria and purchase intention. In the test of the moderation effect between sub-factors of selection criteria and purchase intention, consumers' attitude had a significantly positive influence upon health, convenience, and familiarity, and had no significant influence upon quality and purchase intention. Consumers' trust had no significant influence upon health, convenience, and quality. Results - The study provided several theoretical implications: first, an empirical analysis was undertaken with selection criteria for environmental-friendly agricultural products, consumers' attitude, and trust to investigate subjective norms, attitude toward behavior and control of behavior based on the theory of planned behavior. Second, this study investigated both the mediation effect and moderation effect of consumers' subjective norms on attitudes toward behavior, the mediating effects of perceived behavior control and changes of behavioral intention depending upon size and direction of the variables. This study also provided several practical implications. Conclusions - First, consumption of environment-friendly agricultural products did not increase despite rapid increase of production therefore, promotion of consumption and distribution was needed considering the supply and demand of the products. Second, definite standards for selection criteria were suggested to build up consumers' attitude and trust. Consumers' attitude could be improved by factors including the brand of environment-friendly agricultural products, consistent quality, solving physiological problems caused by adverse effects of environmental problems, supplementary approaches, treatment of adverse effects by eating food, and the development and supply of products in accordance with changes of lifestyle. Finally, consumers' demand for sub-factors of selection criteria could be much higher than health, convenience, and quality of the products. Therefore, a process was needed that could continuously check consumers' needs for the products. Limitations were described at the end of the study.

  • The purpose of this study is to analyze the factors affecting cooperation between industry and public research institutes, in addition to the effects of cooperation between them; on technological and economic performance of firms. Based on existing research relating to the factors affecting industry-university-research institutes cooperation and the relationship between them and firm performance, this study selected the competence of government-funded research institutes, R&D capabilities and organizational characteristics of firms, and support of government and local governments; as factors influencing cooperation between industry and public research institutes. This study sets seven hypotheses on the relationship between the factors promoting industry-public research institute cooperation, technological performance and economic performance. A questionnaire survey was used to collect data for hypothesis testing and 116 questionnaires were completed and used in this research. The PLS-MGA was used as a method for hypothesis testing. In the analysis results, we found that the competence of government-funded research institutes, organizational characteristics of firms, and the support of government and local governments have a positive impact on cooperation between industry and public research institutes. We also found that the collaboration between industry and public research institutes, positively affects firms' technological performance. In addition, we found that the technological performance of a firm, positively affects a firms' economic performance. On the other hand, firms' R&D capabilities have no significant effect on cooperation between industry and public research institutes, and industry-public research institute cooperation does not directly affect the economic performance of firms.

  • This study was designed to develop and test a model of the theoretical structure of factors influencing womens’ attitudes toward menstruation, specifically, premenstrual discomfort or pain, negative affect, disability and role acceptance. The conceptual framework was built through a review of the literature. For the purpose of testing the model, data were collected from April to June, 1992 with the use of Menstrual Distress Questionnaire, Menstrual Attitude Questionnaire, Sex Role Acceptance Scale. Data analysis was done with the SPSS PC/sup +/ for descriptive statistics and PC-LXSREL 7.13 for covariance structure. The study subjects consisted of 320 women college students in 2 three-year nursing junior colleges and 1 department of nursing of a college of medicine. The mean age of the subjects was 19, the mean age at monarch was 13.7, the mean menstrual cycle was 29.7 days and the mean menstrual duration was 5.3 days. The amount of menstrual discharge was moderate and the menstrual cycle variability was within 3 days. The score for pain, negative affect and disability were higher during the perimenstrual period than intermenstrual period. The fit of the hypothetical model with the six paths and the empirical data was high [X²(df=4)=. 57 (P=.966), GFI =.999, AGFI =.997, RMR=.008]. The hypotheses were supported on acceptable level of significance. 1) The higher the pain and negative affect, the stronger the disability. 2) The higher the pain, negative affect and disability, the more negative the attitudes toward menstruation. 3) The lower the women's role acceptance, the more negative the attitudes toward menstruation. The model was supported by the empirical data, and thus these results may help nurses and nursing scientists to understand and support these phenomena of womens’ health experience.

  • Purpose - The purpose of this research is to investigate the effect of ex ante governance mechanisms that can be exercised by franchisers on franchise contract compliance and various relationship outcomes. There are many previous studies on control mechanisms in inter-firm relationship, however, most studies focus on ex post governance mechanisms and identify the effects of behavior control and outcome control on performances. Based on transaction cost theory and agency theory, this study defines the ex ante governance mechanisms of franchisers as contractual completeness and extra contractual incentives. The author have examined the two ex ante control mechanisms on contract compliance, recontract intention, multi-shop running intention and opportunistic behaviors of franchisee. Research design, data, and methodology - In this study, 137 questionnaires of food and beverage franchise stores were collected through a specialized research company. The reliability and validity of the variables were analyzed using SPSS 18.0 and AMOS 18.0 programs and hypotheses were verified through the structural equation modeling. Results - As a result of hypothesis testing, contractual completeness and extra contractual incentives have a positive effect on the contract compliance of the franchisee. It is shown that franchisee's contract compliance has a positive effect on recontract intention and multi-shop running intention and has a negative effect on opportunistic behaviors. Conclusions - This study examines the ex ante governance mechanisms such as contractual completeness and extra contractual incentives, which is relatively rare compared to ex post governance mechanism in B2B relationship. According to the results of this research, these two tools can be used as ex ante control mechanisms for franchise headquarters to use their franchisees. In addition, franchisee's contract compliance affects various relationship outcomes between franchisor and franchisees.
