Purpose - Compared with the past when customers regarded a price factor as one of the most important criteria when choosing a retailer as a shopping destination, they seem to show different attitudes toward retailers in recent. This research, therefore, aims to explore how Korean customers respond to the CSR business activities provided by retailers. Research design, data, and methodology - The authors have developed the 6 hypotheses based on the literature review and adopted the 4 hypotheses after removing the 2 hypotheses through discriminant validity analysis. Results - Amongst the 4 hypotheses selected, H1 (community support), H3 (environment protection) and H6 (trading with unethical suppliers) related to a retailer's CSR business practices are accepted, whilst H4 (product issues) is rejected. Surprisingly, Korean customers are not interested in a product safety issue, when deciding a shopping store. Conclusions - Rather than emphasizing cheaper prices to attract new customers or maintain existing ones, it is demonstrated through the research that retailers have to pay their attention to their CSR activities. For a retailer's CSR practices, the retailer's social role has become more important than ever before, from a customer's point of view.

The aims of this study are to investigate two main problems for the hypothetico-deduction method and to develop a scientific inquiry model to resolve these problems. The structure of this scientific inquiry model consists of accounts of the context of discovery and justification that the hypothetico-deduction holds as two main problems : 1) the heuristic flaw in the hypothetico-deduction method is that there is no limit to creating hypotheses to explain natural phenomena; 2) Logically, this brings into question affirming the consequent and modus tollens. The features of the model are as follows: first, the generation of hypotheses using an analogical abduction and the selection of hypotheses using consilience and simplicity; second, the expansion phase as resolution for the fallacy of affirming the consequent and the recycle phase as resolution for modus tollens involving auxiliary hypotheses. Finally, we examine the establishment process of Copernicus's Heliocentric Hypothesis and the main role of the history of science for the historical invalidity of this scientific inquiry model based on three examples of If/and/then type of explanation testing suggested by Lawson (International journal of science and Mathematics Education, 2005a, 3(1): 1-5) We claim that this hypotheticho-deduction process involving abduction approach produced favorable in scientific literacy rising for science teacher as well as students.

This work studies the variability of flatfish sales revenue. The theoretical analysis draws functions for equilibrium price and quantity using expectation hypotheses. The functions include unpredictable phenomenon with dummy variable and GARCH. The equilibrium function, using adaptive expectation hypothesis, contains the independent variables of supply and demand, while the equilibrium function, embodying rational expectation hypothesis, includes only the independent variables of supply side, because the demand side disappears by the information extraction process theoretically, if economic subjects build the expectation rational. The empirical analysis shows: the variability of flatfish production has a spillover effect on the variability of revenue with the adaptive expectation hypothesis. In the case when the model has a rational expectation hypothesis, the variability of flatfish production has a spillover effect on the revenue (the mean equation of GARCH model). This study indicates that there is the variability in flatfish production and sales revenue, and the spillover effect between them. The result can help to build of the rational system for the fishery income stability.

As the generalization of using computer and the internet, most people, who would decide the acceptance of new information technology (IT), may consider the current systems which have been used so far. The objective of this study was to analyze the relationships between technology acceptance model (TAM) and the switching costs which may incur during switching from the current system into another on. For this purpose, this study suggested the hypotheses, in which continuity cost and setup cost, two types of switching costs in IT adoption, would influence perceived usefulness and perceived ease of use respectively. Moreover, the moderation effects of system types, hedonic system and utilitarian system, on the relationships between switching costs and TAM, were also suggested as the hypotheses. In order to prove the validity of the hypotheses, two groups were surveyed. Before surveying, to the one group who were believed to be a user of 'Cyworld', a new blog service, Naver Blog, was introduced. Similarly, to another group, Google Docs was introduced. The analysis by Partial Least Square (PLS) approach showed that most hypotheses in this study were statistically supported.

The performance of scientific researchers has been studied from a number of different aspects, mostly in developed countries. This paper attempted to identify salient factors influencing scientific performance at individual level in a developing country. A model describing the productivity and performance of scientific researchers was developed. Four hypotheses were derived from the model; i) the degree of diversity of a researcher will affect the degree of his scientific performance, ii) the degree of dedication will affect the degree of his performance, iii) the degree of research pressure will affect the degree of his performance, and iv) the degree of satisfaction will affect the degree of his performance. Data were collected through questionnaires responded by 48 researchers from two research organizations. The results of data analysis supported the hypotheses in part. Specifically, diversity measured by the number of research areas was related to the productivity of research reports (p<0.05); research pressure influenced the average number of research papers (p<0.05). The results of hypothesis testing of the satisfaction showed mixed directions according to the indicators. Even though the results of data analysis did not support the hypotheses unanimously, probably due to the limitation of sample size, most of the descriptive analysis indicated that the direction of hypotheses in developed countries seemed to be similar in developing country too. However, more research efforts are needed to verify the research findings of developed countries in developing countries.

This study investigates the impacts of nuclear energy consumption on environmental quality from a different perspective by focusing on carbon dioxide (CO2) emissions, ecological footprint, and load capacity factor. In this context, the South Korea case, which is a leading country producing and consuming nuclear energy, is investigated by considering also economic growth, and the 1997 Asian crisis from 1977 to 2018. To this end, the study employs the autoregressive distributed lag (ARDL) approach. Different from previous literature, this study proposes a load capacity curve (LCC) and tests the LCC and environmental Kuznets curve (EKC) hypotheses simultaneously. The analysis results reveal that (i) the LCC and EKC hypotheses are valid in South Korea; (ii) nuclear energy has an improving effect on the environmental quality; (iii) renewable energy does not have a significant long-term impact on the environment; (iv) the 1997 Asian crisis had an increasing effect on the load capacity factor; (v) South Korea has not yet reached the turning point, identified as $55,411, where per capita income improves environmental quality. Overall, the results show the validity of the LCC and EKC hypotheses and prove the positive contribution of nuclear energy to South Korea's green development strategies.

The purpose of this research is to propose a program for teaching and learning effective problem-solving for gifted students based on abductive inference. The role of abductive inference is important for scientific discoveries and creative inferences in problem-solving processes. The characteristics of creativity and abductive inference were investigated, and the following were discussed: (a) a suggestion for a new program based on abductive inference for creative outcomes, this program largely consists of two phases: generative hypotheses and confirmative hypotheses, (b) a survey of the validity of a program. It is typical that hypotheses are confirmed in phases through experiments based on hypothetic deductive methodology. However, because generative hypotheses of this hypothetic deductive methodology are not manifest, we maintained that abductive inference strategies must be used in a Creative Teaching-learning Program for gifted science students.

The purpose of this study is in investigating the tax clients for their relationship with tax preparers and the general levels of characteristics for the taxation objects, and establishing significant relationships of the two major factors-satisfaction factors and characteristics of the clients-on the satisfaction of the clients. The results of this study will provide an important basic data required for rational management of tax clients. A total of 20 sub-hypotheses were used, which can essentially be summarized into the following three major statements. The hypotheses investigation results can be summarized as below. First, as for the characteristic factors of the preparer, the taxation knowledge factor and the client satisfaction factor were found to be in a significant median positive relationship, and the experience factor and the client satisfaction factor were found to be in a relatively less significant relationship. Second, the factor on the relationship with the preparer and the client satisfaction factor were all found to be in a highly significant positive relationship. Third, in order to measure the characteristics of the taxation objects, relationships between potential tax reductions factor, probability of taxable income adjustments factor, and the client satisfaction factor were analyzed, and they were found to have positive relationships of relatively high significance. Fourth, the average for the client satisfaction factor by industry was found to be the highest for the manufacturing industry, followed by wholesalers and retailers. Other sectors showed little deviation from the average of 4.9, but this factor was not statistically significant. Fifth, the average difference examination of the satisfaction levels for the clients with or without experience of taxable income adjustments showed that those without experience of taxable income adjustments had higher satisfaction levels. Sixth, 12 study hypotheses had been proposed in order to investigate the relationship between the client satisfaction factors and the client satisfaction levels according to the characteristics of clients. Among the 12 sub-hypotheses, except for the study hypothesis of investigating the relationship between the tax preparer's taxation knowledge and the client's satisfaction levels according to the experience of taxable income adjustments, 11 study hypotheses were all not adopted.
