The purpose of this study examines difference of cunsumer satisfaction by expected selection attribute of wedding dress and bride make-up. It is looking into influencing variables in consumer satisfaction, and is supplying real information to wedding market. The subjects of this study were 241 women getting married within one year of Daegu. The data were analyzed by using frequency, mean, the standard deviation, ANOVA, duncan test, correlation analysis, cross-analysis. Conclusion obtained from the results and discussions of the research are as follows: 1) In the attribution of expected selection according to occupation, blue-collar women are concerned about cost factor but they are low content with the perceptual satisfaction factor. 2) When selecting places for wedding dresses and wedding make-up, in the attribute of expected selection about the number of visiting the shop for wedding dresses and make-up, people who visit over 7 dress shops are highly interested in the appearance fancy degree, advertisements effect factors. But they are concerned with advertisements effect factor, cost factor in the perceptual satisfaction factor about wedding dress. Besides, the more they get chances to visit many dress shops, they are concerned with advertisements, cost factors, and satisfied with both the effect of advertisements and appearance factor degree in the attribution of expected selection about wedding make-up. 3) In the attribution of expected selection about the cost of wedding dresses and make-up, the lower the cost paid, people are interested in price factor. Furthermore, in the attribution of expected selection about the wedding dress and make-up cost, those who spent over 150 million Won are interested in quality, others influence factor, and the case of less than 120~150 million Won, people are highly interested in the appearance fancy degree, advertisements effect factor, and the women are satisfied with the advertisement effect factor in the perceptual satisfaction factor of wedding make-up.

The purpose of the study is to examine the effects of economic factors on depression among the Korean Elderly. In detail, this study is convergence study conducted to understand the moderating effect of economic support from children in the relationship of total cost of living and Depression. For this purpose, this study used the 3,392 Korean elderly from 2015 Korean Welfare Panel Data. As a results, total cost of living of the elderly had a significant effect on depression. Also, the relationship between total cost of living and depression among the elderly was buffered by economic support from children. In other words, the higher economic support from children, the less negative effect of total cost of living on depression. Based on the results, this study discussed that economic factors should be considered as a major factor to reduce depression of the elderly.

The purpose of this study was to explore the consumer responses such as willingness to pay premium and purchasing cost for fair trade coffee as an ethical product while considering the treatment effect of consumer knowledge. First, the levels of consumer knowledge, willingness to pay premium and purchasing cost were presented. Then, the influencing factors on willingness to pay premium and purchasing cost of fair trade coffee were analyzed by applying the treatment effect model. From the results, first, the level of willingness to pay premium was high and consumers having purchasing experience of fair trade coffee spent 9,923 won at once, while less than half of the consumers knew the fair trade coffee. Second, consumer knowledge, ethical judgement, perception of price value, education level and pocket money significantly influenced to willingness to pay premium, while consumer knowledge, information evaluation, importance of fair trade criteria and level of education significantly influenced to purchasing cost for fair trade coffee. Especially, consumer knowledge of fair trade coffee was an important influencing factor for willingness to pay premium and purchasing cost indirectly as well as directly. Thus, this study might provide some useful information for consumers to choose the ethical behavior and the related companies to create effective promoting strategies for ethical products.

We performs the cost-benefit analysis, an economical analysis technique, to measure the effect of a shared public supercomputer. The costs of two given alternatives, to share the public supercomputer in a national center and to employ their own supercomputers in the organizations under the necessity, will be estimated and compared for decision making. In the case of sharing, we can simply predict the cost based on the results of the previous public supercomputer. The cost of individual introduction, however, is almost unpredictable since it has a remarkable variability due to the required system performances, locations, human factor, and so on. Accordingly, an objective and valid method to estimate the cost of individual cases will be proposed in this research. Finally, we analyze the economic effect of operating public supercomputer by comparing the sharing cost with that of the individual employs. The results of analysis confirms that the sharing public supercomputer will reduce the operational cost about 10.3 billion won annually compared with the individual introduction. Accordingly, it is expected that the sharing public supercomputer will bring a considerable economical effect.

Smartphone is becoming as a core device of mobile environment. The purpose of this study is to investigate the factors affecting customer's buying decision on smartphone. Based on prior studies and cases, this study identifies network effect, switching cost, function, design, brand, after service, price as affecting factors of customer's buying decision on smartphone. It also aims to investigate the relationship between network effect/switching cost and re-purchasing. Result shows that network effect brand, after service are significantly related to customer's buying decision on smartphone by device types, but switching cost, function, design, price are not. Network effect also was found to be significantly related to the re-purchasing. The result of this study may provide a guideline of supply strategy with smartphone suppliers.

The cost incurred by voltage sag effect in power networks has always been of important concern for discussions. Due to the environmental constraints, fossil fuel shortage crisis and low efficiency of conventional power plants, decentralized generation and renewable based DG have become trends in recent decades; because DGs can reduce the voltage sag effect in distribution networks noticeably; therefore, optimum allocation of DGs in order to maximize their effectiveness is highly important in order to maximize their effectiveness. In this paper, a new method is proposed for calculating the cost incurred by voltage sag effect in power networks. Thus, a new objective function is provided that comprehends technical standards as minimization of the cost incurred by voltage sag effect, active power losses and economic criterion as the installation and maintenance costs of DGs. Considering operational constraints of the system, the optimum allocation of DGs is a constrained optimization problem in which Lightning Attachment procedure optimization (LAPO) is used to resolve it and is the optimum number, size and location of DGs are determined in IEEE 33 bus test system and IEEE 34 bus test system. The results show that optimum allocation of DGs not only reduces the cost incurred by voltage sag effect, but also improves the other characteristics of the system.

Although the corporate governance plays a crucial role in protecting shareholder wealth, the effect of corporate governance on cost of debt is unclear. On one hand, the corporate governance reduces asymmetric information between corporate and external investor including debtholder leading to a decreasing in cost of debt financing. On the other hand, bondholders require higher rate of return for an improvement corporate governance. Hence, this study aims to investigate the relationship between the mechanism to improve corporate governance namely board effectiveness and the cost of debt in an emerging market. As we aim to explore the relationship between cost of debt and board effectiveness, we select corporation in Thailand as our sample because the businesses in Thailand are major debt-financing. Hence, our sample include listed firm in Stock Exchange of Thailand between 2007 and 2016. Our main findings support the sub-optimal investment hypothesis in that improved board effectiveness is associated with higher cost of borrowing. In addition, we find that the number of board member-board size, the number of board meeting, and the percentage of non-executive on audit committee play are positively associated with the cost of debt financing. Furthermore, we perform two-stage-least square (2SLS) to ensure that our results are far from endogeneity issue.

This paper proposes the cost analysis on the energy efficient equipment when this equipment is participated in the demand-side bidding. Conventional demand-side bidding is exercised through load re-distribution. However if this load reduction is exercised by the use of high efficient equipment, its effect will be assumed to be more economical. This paper analyses this cost-benefit effect of high efficient equipment in the demand-side bidding.

The purpose of this study is to analyze the technical efficiency and its determinants for Korean Apiculture farming by using from door to door and e-mail inquiry data. The analysis was implemented through the Cobb-Douglas stochastic frontier production function (SFPF) model including the technical inefficiency effect model for cross-sectional data. To measure the SFPF model, honey production was used for a dependent variable, and for input variables labor cost, preventive cost, material cost, feeding cost, depreciation cost were used. Farmer's age, farmer's career, farming scale, full-time or half-time firm and movement or fixed firm variables were used to measure the inefficiency effect model. The average technical efficiency on apiculture farming in Korea is estimated to be 0.8112. It means that there were technical inefficiency of about 18.88% in Korea apiculture farming. In this study there are some suggestions which could increase the technical efficiency of Korean apiculture farming.
