In the e-commerce, the conversion into the multi-media is the important issue. According to the research by Nielsen Korea, the 83% of customers who purchase the products in the e-commerce utilize multi-channel to buy the products such as mobile and online [3]. Thus, to effectively implement online advertising, marketers should understand the customers' path [15] in the multi-channel. The study of the multi-site activities plays an important role to predict customers' purchase [28]. To explain the e-commerce site visit activities of customers, we have developed research model in terms of the online advertising. This research model is based on the study of Moe and Fader [23]. There are two types of composition in the research model. First, general site visit as an exploratory search have net effect on the shopping site visit because customers could acquire or develop information on the e-commerce site via online advertising. Secondly, the e-commerce site visit as a goal-directed search cause threshold of the e-commerce site visit because customers could achieve their goal. When the threshold is increased, the probability of a shopping site visit is decreased and vice versa. Thus, we have investigated the impact of customers' previous visit activities (general site visit and shopping site visit) on the next e-commerce site visit in terms of dynamic view. Research data was provided by Cheil World Wide. This panel data include mobile and online log data of panelists from Jan. 2013 to March 2013. As the results, the customers' e-commerce site visit on the online media would decrease the probability of e-commerce site visit because these visit activities increase the threshold of e-commerce site visit. This result is similar with the previous study [23]. Otherwise, since e-commerce site visit on the mobile media decrease the threshold, the customers' probability of e-commerce site visit would increase In summary, the site visit activities on the mobile could improve the probability of e-commerce site visits.

Purpose - This study aims to clarify through which process asset specificity and supplier development project (SDP) affect performance. Cooperation, partnership, the level of information exchange, and the importance of information sharing are considered significant variables as mediators related to the process. Finally, the performance formation model of the supply chain through asset specificity and supplier development project would be suggested as being a result of this study. Research design, data, and methodology - Data collection was as follows: questionnaires were distributed to 250 companies that have business ties with H Company. The empirical study to test our hypothesis was based on statistical analysis (using SPSS 19.0 and AMOS 19.0). The hypothesis of this paper is that the asset specificity and supplier development project variables have positive effects on the following variables: mediators such as cooperation and partnership (reliability and dependence); and the cooperation and partnership variables have a positive effect on the following variables: level of information sharing, the importance of information sharing, and level of information sharing; the importance of information sharing has a positive effect on supply chain performance. We tested our hypothesized model utilizing path analysis with latent variables. Results - First, it was found that asset specificity has significant positive effects on cooperation (H1), reliability (H2), and dependability (H3). Second, it was proved that the level of comprehension on the purpose of SDP has positive effects significantly on cooperation (H4), reliability (H5), and dependability (H6). Third, the hypotheses related to cooperation were all significantly accepted. The relationships of cooperation with the level (H7) and importance (H8) of information sharing were significant. Fourth, the hypotheses related to reliability were all significantly accepted. The relationships of reliability with the level (H9) and importance (H10) of information sharing were significant. In terms of dependability, however, the hypotheses were partially accepted. The effect of dependability was significant on the importance of information sharing (H12), but insignificant on the level of information sharing (H11). Finally, the causal relationships from the level of information sharing to SCM performance (H13) and from the importance of information sharing to SCM performance (H14) were both significantly accepted. Conclusion - First, with rapid changes in the business environment, enterprises should acquire the right information to properly implement SCM. For successful SCM, firms should understand the supplier development project. Second, asset specificity and the level of comprehension on SDP have significant effects both on cooperation and partnership (reliability and dependability). Third, mediators such as cooperation, reliability, and dependability significantly affect the level and importance of information sharing. Fourth, the level and importance of information sharing have significant impacts on SCM performance. This paper makes a meaningful contribution to further the understanding of how SDP affects SCM performance. Finally, successful SCM performance is achieved by information sharing through a collaborative environment and partnership (confidence & dependence) rather than by investing only in setting up an information system.

This study engaged food-service industry workers in Busan (casual dining restaurants and buffets) to investigate the moderating effect of job satisfaction on the influence of emotional labor on turnover intention and job burnout. To accomplish the goal of this study, the statistical programs SPSS 21.0 and AMOS 21.0 were employed for frequency analysis, factor analysis, reliability, and confirmatory factor analysis of responses from f 278 respondents. An examination was conducted to prove the hypothesis based on a structural equation model. There are two sub factors of emotional labor, surface acting and deep acting. According to the result of this study, surface acting has a positive influence (+) on job burnout (exhaustion) while deep acting has a negative influence(-). In addition, job burnout showed a positive influence (+) on turnover intention. It has been revealed that job satisfaction has a moderating effect on the path from deep acting to job burnout. Having considered that job burnout of food-service workers in Busan was related to deep acting, one of sub factors of emotional labors, promoting deep acting appears to be the way of reducing both job burnout and the number of people with turnover intention. Therefore, it is necessary for restaurant owners and CEOs to implement employee training and improve employee benefits in order to promote the deep acting of their employees.

According to previous research, the reason why Design-Build(hereinafter "DB") outperforms Design-Bid-Build(hereinafter "DBB") in terms of cost is due to less change orders(hereinafter "COs"). However, if biddropping was low for DBB resulting into increasing COs, then it would be wrong to conclude that DB is superior due to less COs. Therefore, in order to confirm such misjudgment, the attempt to comprehensively analyze biddropping, COs and delivery method was made as previous methods had analyzed either the relationship between delivery method and COs, or biddropping and COs. This research uses path analysis, which simultaneously compares effect sizes on COs according to delivery method and biddropping based on the project type, and validated the mediator effect. The research proved that DB outperforms DBB due to less COs cannot be validated as biddropping caused a mediator effect by intervening between the delivery method and COs for specific project types. Therefore, the mechanism of delivery method acts on COs through biddropping was established. Also, the identity of biddropping was investigated in a different perspective from previous research. Based on this result, this research is expected to help determine a delivery method by considering the mediator effect of specific projects and evaluate performance.

Technology based civilization has made a sustained advancement, resulting in economic growth and material prosperity. The outcome was the beginning of environmental destruction. Especially, in regard to construction, it has been recognized as a key culprit for pollution. As such, the construction industry has recently shown interest in the environment, as it has been applying environment friendly method of construction and reducing wastes. As the number of old common housing increases in our country, reconstruction and remodeling are implemented as a means of improvement. However, it can be said that remodeling is the inevitable option because of cost and environmental problems associated with reconstruction. As part of its feature, remodeling work is preceded by removal work. And, removal work inevitably creates construction wastes. Treatment of wastes that takes into consideration environmental aspects is important and for this, removal work that is based on environment friendly remodeling to ensure selective separation must be implemented. Yet, a removal work based on environment friendly remodeling has a lower level of output compared to existing methods. Because remodeling work by its nature has a post construction work which proceeds after it, securing work efficiency is important as the removal work is a critical path activity. Thus, the present study improves the work process of a removal work that is based on environment friendly remodeling so that it becomes a work process that includes work efficiency. For this, as a case study, old common housing has been selected, and a TACT process has been developed which is based on data acquired from environment friendly removal work. And, this study develops an optimal TACT process which is based on environment friendly remodeling by conducting a simulation for a 15 floor apartment.

This paper examined the evolution and development strategies of Young-deung Festival holding in Chindo since 1978. The Young-deung Festival is a representative event tourism in Korea. The water between Hoidong and Modo in Chindo, a small islet 2.8km off the coast, part to reveal a path 40m wide as a result of the moon influence on the tides. This phenomenon is called “young-deung-sal”on the Chindo. This event began on a small scale highlighting the treasury of traditional folkfore and shamanism peculiar to these islands, various cultural resources, and local place attraction such as young-deung-sal. But, in the early 1990s, with the introduction of systematic management and a variety of programs, the small village festival has steadily evloved in the scale aspects of the program, budget, profit, and the number of visitors participating in festival. In addition, the period of festival was prolonged for three days and visitors from other provinces have steadily increased, in particular visitors from Seoul and Gyoungkee have steadily increased. In order to develop the Young-deung Festival, the followings should be done: creation of local image through place attraction, private organization in supporting festival, adoption of management techniques for the local economic activites, and extension of linkage with tourists places around Chindo, target visitor marketing through a continuous visitor survey.

To examine how usage of social network services(SNS) can affect users' satisfaction through their involvement to SNS. This study first explored the usage motives on the SNS by reviewing previous studies which are from the perspectives of usage and gratification theory. The structural equation modeling(SEM) approach was used to validate the model and Lisrel was used to analyze 306 data which were collected from college students who have SNS using experiences. The results showed that the motives of information seeking and self-expression have no significant influence on affective involvement to SNS and other hypotheses were all accepted. In order to investigate the relationship of usage motives-involvement-satisfaction between different genders, path analysis in male group and female group were done respectively. The results showed that in the case of male group, the motivation of information seeking, entertainment, and self-expression have positive effect on affective involvement, while only the entertainment motive can increase the cognitive involvement. In the case of female group, socializing motive and entertainment motive have positive effect on both affective involvement and cognitive involvement, but the information seeking motive and self-expression motive can not influence the formulation of emotion in SNS.

Relationship marketing has been dealt with as an effective strategy for customer loyalty in prior research. It seems to be essential that organizations should make efforts to develop successful relationship between the organizations and the customers. However, a customers' voluntary efforts are also needed to strengthen the relationship meaningfully. Relationships are built on the foundations of mutuality. In other words, customers' efforts are necessary for relationship development, as well as an organization's efforts. Hereby, the role of customers for the development of a relationship with an organization has been overlooked in previous research so far. This study applied the Self-Determination Theory (SDT) to explain the role of customer motivation in developing customer relationship. Thus, the author chose customers who have experienced medical service recently as survey participants. Then, this paper verified the path relationships between self-determination factors (autonomy, perceived competence, relatedness) and relational factors(shared responsibility, commitment, relationship retention). It suggested that role of customers is inevitable in developing the relationship. In conclusion, this research has several implications on relationship marketing. For service providers, they should understand that the customer's perceived self-determination can improve tangible and intangible performance in relationship development.
