  • The objective of the study is to investigate factors affecting consumers' purchase intention toward imported organic agricultural products. To accomplish the goal of the study a consumer survey was administered for randomly selected households residing in capital area. Results show that the more consumers trust a safety of domestic products and a certification system, the less they purchase the imported products. In addition, it is demonstrated that educated consumers are relatively less reluctant to imported organic agricultural products. Finally, an improvement of domestic certification system, decrease of price of environmentally friendly agricultural products, and aggressive promotion are required to enhance the competitiveness of the domestic environmentally friendly agricultural products.

  • There is a consensus in the field of vehicular network security that public key cryptography should be used to secure communications. A certificate revocation list (CRL) should be distributed quickly to all the vehicles in the network to protect them from malicious users and malfunctioning equipment as well as to increase the overall security and safety of vehicular networks. Thus, a major challenge in vehicular networks is how to efficiently distribute CRLs. This paper proposes a CRL distribution method aided by terrestrial digital multimedia broadcasting (T-DMB). By using T-DMB data broadcasting channels as alternative communication channels, the proposed method can broaden the network coverage, achieve real-time delivery, and enhance transmission reliability. Even if roadside units are not deployed or only sparsely deployed, vehicles can obtain recent CRLs from the T-DMB infrastructure. A new transport protocol expert group (TPEG) CRL application was also designed for the purpose of broadcasting CRLs over the T-DMB infrastructure.

  • Background : The prevalence of the chronic metabolic disease is increasing due to the aging society. Therefore, Korean Society of Health-system Pharmacists (KSHP) has a specialty pharmacist system to improve the professionalism of pharmacists. The purpose of this study is to suggest the difference between specialty pharmacist and non-specialty pharmacist with regards to their knowledge, delivery of information on medication, service provision, and job satisfaction. Methods : An online survey research was conducted for hospital pharmacists. The reliability of the questionnaire items was presented using Cronbach's ${\alpha}$ test. The t-test or ANOVA analysis was used for evaluating differences in continuous variables. Results : A total of 171 pharmacists responded to the questionnaire, and 87.7% of the respondents were aged less than 30 years (76.6%) and four-year graduates (86.0%). Typically, 108 (63.2%) were candidates for the pharmacist's specialty certificate, and the remaining 63 (36.8%) were not enrolled. Considering the field of specialty with overlapping, the total number of certificated patients was 140 (26.3% of the total of 532 in 2016). The results of the reliability analysis of the specific questionnaire showed that the Cronbach's ${\alpha}$ value was over 0.78. There was no significant difference in customer directionality between the two groups. However, there was a significant difference (p<0.05) with respect to overall knowledge about the treatment process, drug efficacy, and side effects, information about medicines and adverse drug reactions, and in providing appropriate information to medical staff including patients and physicians. Conclusions : The pharmacist with specialization showed a positive result of self-evaluation of items such as knowledge about drugs, communication of information on medications, and service provision, compared to other pharmacists, and the result was in correlation with the numbers of specialization. There was no difference in job satisfaction related to working environment. Henceforth, it is hypothesized that there is a necessity for continuous improvement in the working environment to suit the purpose of the pharmacy specialist system.

  • In a fiercely competitive environment, quality is a key factor that enables dashboard camera makers to maintain their competitive advantage. Quality affects consumer satisfaction, brand loyalty, and firm performance. Therefore, to remain competitive, it is important that manufacturers maintain product quality that meets consumer expectations. To this end, it is necessary to investigate customer preferences and product performance in terms of product quality and to properly allocate resources to improve the quality level such that the firm can maintain a competitive advantage. In this paper, we proposed the various ways in which manufacturing firms can determine which quality dimensions need improvement in order to secure competitiveness. To this end, we analyzed a case study of Urive to develop a quality improvement strategy through importance performance competitor analysis (IPCA). Urive's IPCA results showed that 14 quality dimensions, namely performance, size, price, ease of use, country of origin, manufacturer, brand, product certificate, warranty, distribution channel, market share, reliability, durability, and conformance, were not absolutely competitive compared with those of Mando, Inavi, and Finevu. In terms of color, Urive had an absolute competitive advantage over Mando, but not Inavi and Finevu. Urive's appearance was more competitive than Mando's, but not Inavi's and Finevu's. In terms of advertisement and serviceability, Urive was absolutely less competitive than Mando and Inavi, but had a competitive advantage over Finevu. Therefore, it is necessary to put resources and time as the first priority for performance, reliability, and durability, which have a large performance difference in common among the three brands. The quality dimensions in which resources and time need to be put in second place are price and ease of use, which have a large performance difference in common among the two brands.
