This study started why do consumers use the counterfeit goods. We executed the pretest through the depth interview, and made an purchase motivation scale, useful benefit factor and cost factor scale of counterfeit goods. We found out having the recognition difference of China consumers with Korea about these. The results is as follows. First, A counterfeit motivation appeared to the recognition difference appeared in a ostentation, economical efficiency and self-satisfaction factor with korea and china consumers. Second, counterfeit useful benefit factor organized to a personal significantly and economic benefit and the recognition difference appeared. Third, Counterfeit good useful cost composed to the personal good-quality, economic and social image of cost factors, and the recognition significantly difference appeared to all of cost factors with Korea and China consumers. These results are helpful for a depth understanding about the counterfeit use behavior, and will be utilized for the public campaign to reduce such behavior.

Recently social commerce has become an issue in E-commerce. It was made in purpose to seek the satisfaction of consumers plan to shop attempts to boost use of social commerce. Social commerce motives and benefits and loss factors are examined the impact of purchase satisfaction. Statistical analysis was performed using the multiple regression analysis. The results were as follows. First, economic incentives and hedonic motivations and opportunistic motivation factor had a significant effect on purchase satisfaction. Second, the benefits are psychological factors and price benefits had a significant effect on purchase satisfaction. Third, the more it feels less sense when using social commerce and economic losses, as used to feel less discomfort were higher purchase satisfaction. Finally, it was confirmed that the greater the relative benefit factors influence than the loss factor. This study is significant in that it provided meaningful data from the viewpoint of a consumer who uses social commerce sites.

태양광발전 시스템의 성능 평가는 신뢰할 수 있는 데이터의 취득 및 분석을 통하여 발전성능을 제시할 수 있다. 발전성능에 영향을 미치는 요인으로는 일사량과 온도 등의 환경적인 요인, 시스템 구성에 따른 기술적인 요인에 의해 결정될 수 있다. 특히, 시스템 구성에 의해 결정되는 기술적인 요인은 태양전지 모듈의 어레이 손실 및 BOS의 자체 손실 등을 분석하여 전체 시스템의 발전성능을 분석하여 그 성능을 평가할 수 있다. 본 논문에서는 기 설치된 태양광발전 시스템에서 취득된 데이터를 통하여 용량별, 지역별에 따른 태양광발전 시스템의 성능 분석과 손실 원인을 분석하였다. 분석결과 시스템의 성능은 환경적인 요인과 기술적인 요인에 의해 발전성능이 달라진다는 것을 확인할 수 있었다. 본 논문의 결과는 향후 태양광 발전 시스템의 성능의 기준을 제시하는 연구를 위한 사전연구로써 유용한 자료가 되리라 믿는다.

Recently commercialized network are getting more and more popular, bringing dramatic change to the market. We can predict the future of the E-commerce. The ongoing E-commerce and SNS （Social Networking Services）related E-commerce are increasing greatly both in Korea and China. This research tries to focus on Chinese consumers using E-commerce. The study has four findings. Firstly, the E-commerce consumers consider four factors including price, convenience, products and website, which affect the sellers' integrity. Secondly, E-commerce will affect sellers' integrity. Third, there are 4 factors which affect the sellers' integrity: service, price, products and the information. Fourth, the factors which affect the integrity of sellers are the value, happiness and practical. This study want to give some hints to the E-commerce in the overseas market in China.

Establishment of practicalization technologies is becoming more important as dissemination of domestic PV system has been increased. To improve performance through PV system optimization, this paper presents loss factors analysis of PV system based on results of field operational test. Also, as simulation results are compared with actual operational ones, the main loss factors of PV system due to performance degradation are reviewed.

This study was to investigated why consumers buy counterfeit luxury goods, and to address questions about what was used. To this end, benefits consumers experience using counterfeit or what is profit? In addition, experience using counterfeit what is lost or dissatisfied? Based on the results of previous studies on the use counterfeit motivation, loss of use, benefits, and behavioral factors associated with motivation to learn using these counterfeit goods, benefits, and loss factor, each counterfeit product attitude and purchase intention was affects. First, the motivation for using counterfeit display, economics, satisfaction, usefulness, respectively. Counterfeiting in the attitude demonstrated motivation and quality had a significant impact. The economics of buying a counterfeit, satisfaction and quality significantly affected the motivation. Second, counterfeit benefits and economic benefits, personal benefits factor, respectively. Counterfeit goods on the attitude factor has significant effect personal benefit. Purchase of counterfeit goods, the economic and personal benefits also had a significant impact. Third, the loss factor counterfeit personal loss, quality loss, material loss, and social factors were lost. Attitude toward counterfeits were no significant factors that affect. The social cost of buying a factor had a significant impact. These findings on the behavior of consumers with counterfeit deep understanding helps. In addition, to reduce the future use of counterfeit campaign gives data that can be exploited.

This study sought to confirm the impact of analytical methods and behavioral economic theory factors on decision-making when making chartering decisions in the dry bulk shipping market. This study on chartering decision-making model was began to verify why shipping companies do not make rational decision-making and behavior based on analytical methods such as freight prediction and process of alternative selection in the same market situation. To understand the chartering decision-making model, it is necessary to study the impact of behavioral economic theory such as heuristics, loss aversion, and herding behavior on chartering decision-making. Through AHP analysis, the importance of the method factors relied upon in chartering decision-making. The dependence of the top factors in chartering decision-making was in the following order: market factors, heuristics, internal factors, herding behavior, and loss aversion. Market factors, heuristics, and internal factors. As for detailed factors, spot freight index and empirical intuition were confirmed as the most important factors relied on when making decisions. It was confirmed that empirical intuition is more important than internal analysis, which is an analytical method. This study can be said to be meaningful in that it academically researched and proved the bounded rationality of humans, which cannot be fully rational, and sometimes relies on experience or psychological tendencies, by applying it to the chartering decision-making model in the dry bulk shipping market. It also suggests that in the dry bulk shipping market, which is uncertain and has a high risk of loss due to decision-making, the experience and insight of decision makers have a very important impact on the performance and business profits of the operation part of shipping companies. Even though chartering are a decision-making field that requires judgment and intuition based on heuristics, decision-makers need to be aware of this decision-making model in order to reduce repeated mistakes of deciding contrary to market situation. It also suggests that there is a need to internally research analytical methods and procedures that can complement heuristics such as empirical intuition.

Multiple regression equation was derived for estimation of slump loss in ready mixed concrete and usefulness of the equation was verfied by field test. Factors affecting slump loss were examined and analyzed for transport distance and transport time of ready mixed concrete. The analysis showed that wait and discharge time of ready mixed concrete in job site caused difficulty in the slump control. To determine the influence of the other factors such as mix proportion, temperature of concrete, and dosage of admixture, experimental tests were performed. Generally, there was no significant difference in slump loss according to cement content and initial slump level. For one retarder, more slump loss was found, but difference according to dosage of admixture was not recognized.
