In this paper, we suggest a new backorder policy for stockout which is occurred in each regional distribution centers of distribution chain for capital-goods product. In backorder process of backorder policy, minimize expected stockout through the balancing-division module, and has occured stockout is backordering through the emergency supply from central distribution center and regional distribution center. Simulation tests show that our backorder policy is on the decrease of backorder cost and improvement of customer service. Our backorder policy has two important benefit. First, customer service level is improved by realization of minimum stockout. Second, the backorder process by allowance of the same level supply is to decrease system operating cost.

The reverse transcriptase polymerase chain reaction (RT-PCR) was used for the detection of bovine coronavirus (BCV) in fecal samples by using reverse transcriptase and two primers which flanked M gene sequence of 407bp. RT-PCR detected bovine coronavirus specifically, but did not detect mouse hepatitis virus (MHV), transmissible gastroenteritis virus (TGEV), and bovine rotavirus (BRV). The M gene sequences of MHV are homologus to that of BCV, but minor differences exist in the primer regions, preventing annealing of the primers. Detection of BCV using RT-PCR was compared with ELISA and the agreement of BCV detection by RT-PCR and ELISA was 95.3%. RNA detection in positive clinical specimens was significantly better by PCR than immunological detection of BCV by ELISA.

The purpose of this study is to consolidate the position of Kunsan Port as a Hub-port in Northeast asian region with the development of Kunsan port's hinterland. To accomplish the purpose, this paper firstly reviews the concept and function of port's hinterland literally. Next, We attempt to grasps the trends of port logistics service in this region, and to cope with this trends, study the previous researches of logistics platform(LP). Based upon the study, We find out the main factors of improving efficiency in port logistics, and build the model of logistics strategy with such factors as (1) Environment (2) Marketing (3) Logistics Chain and (4) Logistics community. And in order to applicate the model, we analyze the current situation of Kunsan port and port's hinterland. Finally, we provide the logistics strategies in Kunsan port's hinterland.

Avian adenoviruses are diverse group of pathogens and recently hydropericardium hepatitis syndrome (HHS) Is an important, emerged disease of poultry. Particularly 2-3 weeks old age broilers increased mortality ranging from 20-30% and brown native chicken 3-7 weeks sudden onset with mortality 20-50%, typically development secondary infection. The infection chicken shows liver enlarged, pale and straw- colored fluid is present in the sac surrounding the heart. Histopathological positive samples have necrotic foci and basophilic intranuclear inclusion bodies in the hepatocytes and polymerase chain reaction (PCR) was useful for detect the fowl adenovirus (FAV) associated with HHS.

버추얼 커뮤니티(Virtual Community)와 이를 모바일 환경에 응용한 모바일 커뮤니티(Mobile Community)에 관련된 학술적, 산업적 연구는 다양한 분야에서 활발하게 진행되고 있다. 그러나 현재의 모바일 커뮤니티 연구는 사회적 네트워크 서비스 (Social Network Service)에 치중되어 있기 때문에 모바일 커뮤니티를 비즈니스 환경에 접목하려는 시도는 미흡한 실정이다. 본 논문에서는 모바일 비즈니스 환경에 커뮤니티 개념을 도입하고 모바일 비즈니스 커뮤니티 서비스라는 새로운 가치를 창출할 수 있는 가치 사슬(Value Chain) 및 서비스 모델을 제안한다.

With the emergence of new digital technologies into a supply chain, it is essential for companies to incorporate these technologies in managing their supply chains. However, various challenges have been identified in digital supply chain management, especially when it comes to its assessment. There are no universally agreed measurements for the performance of digital supply chain management within the research community so far. This paper explores an option of using user experience as one of possible measurements. Therefore, three different focus-group discussions were held and later analyzed with a qualitative content analysis. The subscription-based video on demand service, Netflix was used as an example in those discussions. Due to the fact that Netflix provides a digital product as a streamline service, user experience is critical for the company. Especially, user experience with a recommender system and related privacy issues have become significant for a company to retain existing customers and attract new customers in many fields. Since the recommender system and related privacy issues are parts of a digital supply chain, user experience can be one of appropriate measurements for digital supply chain management. This study opens a new perspective for research on performance measurements of digital supply chain management.

The firms aim to acquire services and costs advantage from logistics outsourcing strategy. But it is very important to select optimum service provider. A checklist of the criteria for the evaluation of service providers follows : service quality, low cost, logistics information system, service network, financial stability, investments in plant and equipment, management attitude and lookout for the future strategic fit, cultural and psychological barriers etc. Also, a 8-step implement of logistics outsourcing strategy will be of help for maximizing benefits of logistics outsourcing. It follows : 1-step : logistics environment analysis, 2-step : check service provider availability, 3-step : logistics outsourcing determinant analysis, 4-step : select of optimum service provider, 5-step : contract with optimum service provider, 6-step : identify of remaining barriers, 7-step : performance of logistics outsourcing, 8-step : evaluation.

Supply chain management can be defined as an information system that connects the inside and outside of a company. Its purpose is to systematically and strategically manage the flow of information, resources and services to improve the long-term performance of the entire organization, including individual companies connected to the supply chain, and the quality of service provided to customers. The ultimate goal of SCM is to create synergy through organic integration of supply and demand based on cooperation and collaboration with stakeholders in the supply chain. This study is based on the hypothesis that the company's management performance will improve as the level of SCM improves. Most of the previous studies dealt with the relationship between corporate performance and SCM in the IT area. In this study, research was conducted through human capacity with IT system. The causal relationship was demonstrated, and there was a difference in the perception of the results of this study depending on whether or not smart factories were consulted in the era of the 4th Industrial Revolution. There is a need to examine the links between management's value chain and its causal relationship.
