Holding conventions and exhibitions are deemed as a highly valued-added services. The conventions and exhibitions industry (CEI) contributes to the development of the region in which the venues are located by creating jobs, boosting the local economics, attracting dollars and increasing tax incomes. At the same time, the international awareness of the region rises after holding an international exhibition or convention. This study investigated the effects of outsourcing services quality that employed by corporations organizing conventions and exhibitions on business performance and customer satisfaction of organizing corporations. It was found that many convention organizing corporations relied on outsourcing services for the most of the process. Given that the staff members of outsourcing companies serve as the major source of services for events, the quality of their services has much effects on the business results of hiring corporations. In this study, major factors influencing the service quality and the importance of the service quality were addressed. And the ideas for effective method for controlling the outsourcing sources were also suggested for hiring corporations and outsourcing companies.

Today, many organizations, including venture companies, are focusing on attention on securing and attracting talented people, and on the job satisfaction of their members. However, many organizations, including venture companies, lack understanding of work-family interaction. This study was conducted to investigate the interactions between work and family. Specifically, this study aims to verify the mediating effects of paternal involvement in child care, specifically effects on influences of autonomy at work over satisfaction at work for Dual-income married man living in Gyungbuk province, whose spouse is also working. In order to achieve the aim, I conducted survey from August 29 to September 22 in 2014, targeting married man living in Gyungbuk province, and collected data were analysed using SPSS 20.0. Characteristics of each factors were analysed through frequency and descriptive statistic analysis, and correlation, causal relation, and mediating effects of factors were analysed through correlation analysis and hierarchial analysis. The summary of this study is as follows. First, satisfaction at work for married man showed positive relations with all the sub factors of autonomy at work and paternal involvement, which are housekeeping activities, cognitive fulfillment counselling, life style counselling, and leisure activity participation. Second, satisfaction at work for married man appears to be affected by autonomy at work, life style counselling, leisure activity participation, monthly income, and occupation. Also, in relationship between autonomy at work and satisfaction at work, life style counselling and leisure activity participation, that are sub factors of paternal involvement, appeared to be partially mediating. Therefore, in order to improve the job satisfaction of men, it is necessary not only to increase job autonomy, but also to improve the job satisfaction by preparing ways to parenting involvement.

Mobile phone-related industries have been mainly concentrated on attracting the new customers and increasing the market share such as for the aggressive marketing activities, but it is the time to find an effective strategy to preserve existing customers since the mobile phone market had already reached the saturation. In this study, the properties of mobile phone that influence on the choice of handset and telecom company were analyzed. General properties of respondents were explored and the mobile phone properties were grouped by common factors. And analyzed the effect of factors on customer satisfaction with structural equation model. 10.4% of respondents are used their handset more than two years and 48.7% wanted to purchase other manufacturer's handset if they repurchase mobile phone. These results might come form the fact that the life cycle of mobile phone become shorter by the heating competition in mobile phone market and, to some degree, the influence of smart phone which recently become globally popular. Four factors, 'Hardware Quality', 'Practicality', 'Convergence Functions' and 'Level of Awareness', are induced from the mobile phone properties. In Structural Equation Model analysis, 'Hardware Quality' and 'Practicality' have significant and positive effects on Customer Satisfaction. But, 'Awareness' such as brand and trend appeared quite less influence on the customer satisfaction.

To identity the composition and ratio of the sex pheromone in the asiatic leafroller, Archippus breviplicanus (Walsingham), which is a major pest on apple leaves, and to develop a monitoring system using this sex pheromone, abdominal tips of their virgin female during the calling period were extracted and analysed. The GC/GC-MS analysis revealed the following three compounds; (E)11-tetradecenyl acetate (E11-14: Ac), (Z)11-tetradecenyl acetate (Z11-14: Ac), and tetradecyl acetate(14: Ac) with the ratio of 56:22:22. Electroantennogram (EAG) assay was also conducted to examine biological activity of the components. The three components evoked significantly higher responses than hexane or air but there was no significant differences between the mixtures made by components. Field trapping experiments for determining the optimum blend, seasonal fluctuation and the optimum amount for male attracting were carried out over 4 years from 1997 to 2000. Although male moths were attracted to 8:2 and 7:3 between E11-14: Ac and Z11-14: Ac, their 7:3 blend was found to be the most effective. Archippus breviplicanus appears to occur three times a year in Korea. The optimum amount for monitoring was found to be 1mg per trap. 14: Ac, the third component, did not show synergistic effect on male moth attraction.

Sunflower, selected as a trap plant that can be controlled by attracting Ricania spp. adults via attraction has the highest attractiveness during the preoviposition period. Considering the ecological characteristics of Ricania spp., adults are distinguished by the preoviposition and oviposition periods and the attractiveness of sunflower to Ricania spp. adults was 91.4~95.2% higher than that of blueberry during the preoviposition period. On August 20, when Ricania spp. adults entered the oviposition season, sunflower attractiveness was low at 9.8~11.6% owing to preference for tree species. Based on the result of the selection of systemic chemicals that could be used concomitantly with sunflower, all chemicals, except etofenprox, showed a high controlling effect of over 90%, and among them, dinotefuran showed the highest insecticidal rate of 95.8%. The systemic chemicals acetamiprid, dinotefuran, thiamethoxam, and imidacloprid persisted for 13 days (survey period). Therefore, the concomitant use of sunflower and systemic chemicals can reduce the density of Ricania spp. entering farmlands and their populations in surrounding habitats, which are expected to help in stabilizing the ecosystem.

Recently, as the income level of consumers increases, interest in tourism products has increased, competition among tourist destinations has been fierce. Storytelling ads are drawing attracting attention as one of the ways to establish differentiated positioning for tourism products. This study investigates the role of the involvement of tourism activity in the storytelling ads effects, and examines the effects of the attitude toward storytelling ads on tourist destination commitments, visit intention and SNS WOM (word-of-mouth) intention. This study also empirically tests the role of mental simulation in the relationship between storytelling ads attitudes and visit intention. A total of 255 usable responses were obtained from a sample of 270 consumers aged 18 or older in South Korea. Following the two-stage approach of model validation, measurement validity of each construct appearing in the structural model and hypothesized structural paths were tested. The findings show that all hypotheses are supported except H3 that posits the impact of attitude toward the storytelling ads on visit intention and mental simulation showed a moderate effect on the relationship between ads attitude and visit intention in the case of rational appeal. This study suggests that the production of storytelling ads of tourist destinations can be effective strategy to improve regional competitiveness and increase visit and SNS WOM intention.

There is an increasing need to foster new industries at the local level. This study aims to analyze the spatial patterns of new industries in Korea from 2007-2017 and to figure out its determinants of agglomeration in 2017. Through this study, it is found that new industries are unevenly distributed around Seoul Metropolitan Area(SMA). The regional disparity between SMA and non-SMA is prominent. Furthermore, new industries represent a strong spatial positive autocorrelation, showing a strong concentration on a few regions in Korea. This study explores the determinants on agglomeration of new industries with spatial statistical model. From the results of spatial error model, it is indicated that the number of graduate students, the ratio of technology based start-ups, and the number of elementary, middle, and high schools have a significant effect on new industries. In addition, the specialization and the diversity of industrial structure on knowledge-based manufacturing industries and knowledge-based service industries have been statistically significant. This study provides implications that non-SMA needs policies with respect to attracting talented people, developing human resources, and improving regional environment in order to improve regional competitiveness in promoting new industries.

In a situation where there is excessive competition among logistics centers due to the low price of logistics centers for attracting freight volume, the conditions provided by the logistics centers are similar. Therefore, in order to determine the logistics center, we want to find out what kind of differentiated service the shippers desire, as well as what level of service they want in addition to al ow price. There are currently no studies about the service quality of logistics centers. The components of the service quality of the logistics center were extracted by applying them to the logistics center based on the existing service quality theory. Factor analysis revealed five dimensions of service quality: tangibility, reliability, empathy, assurance, and know-how. It was found that service quality had a statistically significant influence on customer satisfaction, from the investigation of the causal effect relationship. In addition, 'Know-How' among these factors has more influence on customer satisfaction, so it is important to accumulate differentiated 'Know-How' only in logistics centers.

Recently, DVC (Distributed Video Coding) is attracting a lot of research works since this enables us to implement a light-weight video encoder by distributing the high complex tasks such as motion estimation into the decoder side. In order to improve the coding efficiency of the DVC, the existing works have been focused on the efficient generation of side information (SI) or the virtual channel modeling which can describe the statistical channel noise well. But, in order to improve the overall performance, this paper proposes a new scheme that can be implemented with simple bit operations without introducing complex operation. That is, the performance of the proposed scheme is enhanced by using the fact that the Wyner-Ziv (WZ) frame and side information are highly correlated, and by reducing the effect of virtual channel noise which tends to be clustered in some regions. For this aim, this paper proposes an efficient pixel-domain WZ (PDWZ) CODEC which effectively exploits the statistical redundancy by using the code conversion and Gray code, and then reduces the channel noise by using the bit interleaver. Through computer simulations, it is shown that the proposed scheme can improve the performance up to 0.5 dB in objective visual quality.

Formal net charges, bond populations, atomic orbital coefficients, energy components and conformation of dimethyl-2,2-dichlorovinylphosphate have been studied theoretically by using the CNDO/2 molecular orbital calculation method in attempt to describe the reactivity and the stability of the molecule. From the analysis of rate equation, molecular orbital calculations and identification of the hydrolysis products, 2,2-dichloroacetaldehyde and dimethylphosphoric acid, a mechanism of the hydrolysis of dimethyl-2,2-dichlorovinylphosphate(DDVP) has been proposed. The hydrolysis of DDVP proceeds through the mechanism of nucleophilic addition, typical Micheal reaction in basic media. Therefore, it appears probable that the attack by strong nucleophile, hydroxide ion occurs at the increased positive charge $C_2({\alpha})$ atom of a staggered conformation due to the inductive effect (-)I>(+)R of 2,2-dichlorovinyl, electron-attracting group. And then, the hydrolytic scission involves the $C_2({\alpha})-O_3$, ${\pi}-anti-bonding\;orbital({\pi}^*)$ in the subsequent reaction in aqueous solution.
