Hazard Analysis Critical Control Point (HACCP) system application is expanded to food chain from farm to table to supply safe livestock products with consumers in Korea. The objectives of this study were to analyze the HACCP operating conditions in butcher shops and to suggest for better HACCP implementation. We analyzed the HACCP inspection reports for butcher shops implemented by the Korea Livestock Products HACCP Accreditation Service from 2007 to 2009 and from 2010 to 2012 to compare the rate of HACCP non-compliances. The overall rate of non-compliances was higher in 2010~2012 than 2007~2009. The current inadequate HACCP operating level was directly related with the business size. Ninety-nine percent of the butcher shops were very small business with under 10 employees in Korea, and these small-sized businesses usually had great difficulties in implementing HACCP due to lack of technical expertise and financial resources. To overcome the obstacles and to facilitate more effective HACCP application and operation in butcher shops, government should play a leading role in developing flexible and simplified HACCP-based system which merges both the pre-requisite and HACCP principles.

본 연구에서는 특정 D 광역시를 대상으로 생활폐기물 처리과정에 대한 역물류(Reverse logistics: RL)네트워크를 구성하고 이를 효율화하기 위한 방법론을 개발했다. 현재 D 광역시에 속한 8개 기초자치단체들은 각 기초자치단체별로 자체적인 RL네트워크를 구성하여 생활폐기물을 처리하고 있다. 그러나 현재와 같은 방법은 운영상의 비효율적인 측면이 있으며, 이를 개선하기 위해 새로운 개선방안을 마련했다. 사례연구에서는 D 광역시 8개 기초자치단체에서의 운영자료를 기초로 하여 기존운영방식과 개선방안에 대한 비교분석을 실시하였으며, 그 결과 개선방안이 기존운영방식보다 더 효율적이라고 분석되었다.

Concerns about food safety continue to rise and under this situation, governments of some countries have reinforced their regulations more strictly for food safety. In order to prevent food safety incidents or, at least to minimize the impact, the preparedness is very important. As a consequence of this, traceability system has become an essential tool for food safety. Recently, it requires more prevention-based food safety control system. One of the most generally used systems for food safety control is Hazard Analysis and Critical Control Point (HACCP). Both traceability and HACCP systems can be integrated through Electronic Product Code (EPC) Sensor Network technologies which have four value propositions. In this paper, we will introduce the concept of product and process traceability system (P2TS) through the integration of three systems to improve food safety management. The final aim is to find out the added values of the P2TS.

With the diffusion of the Internet, firms try to electronically collaborate with their partners in order to cut costs and gain profits. This, electronic Partnership, called 'Collaborative IT' is quite popular between large purchase enterprises and small-to-medium sized sub-contractors. This study investigates such relations. This study proposes three groups of research variables-interorganizational relationship, collaborative IT activity, and firm performance. the interorganizational relationship consists of trust, commitment, and asymmetry of commitment. Collaborative IT activity is composed of information sharing and workflow integration. The ultimate dependent variable is firm performance. It is hypothesized that the relationship factors influence the level of collaborative IT activity, while the latter in turn affects the firm performance. The relationship factors nay also directly affect the dependent variable. In addition, collaborative IT motive, as a moderating variable, may influence the causal relationship. By means of survey, ore hundred and eighty-two responses were obtained. Most sample companies are small-sized, in the manufacturing sector. The analysis of data reveals that both trust and commitment positively affects the level of collaborative IT activity, while asymmetry of commitment has negative effects. The workflow integration is significantly related with firm performance. Information sharing, however, has no signific3nt effects. Furthermore, asymmetry of commitment shows reverse relationship with firm performance. Collaborative IT motive works as a moderating variable between information sharing and firm performance. Finally, workflow integration is believed to mediate between relationship factors and firm performance.

Background: It is well known that the distribution of therapeutic materials is very complex. However, it is not easy to demonstrate the concrete problems caused by distribution channels empirically. The purpose of this study was to investigate the differences in the price of therapeutic materials according to the type of purchasing agency and the way in which medical institutions purchase therapeutic materials. Methods: This study compared the claimed prices and the maximum allowable prices for the items of therapeutic material used for general spinal surgery. Results: Ilsan Hospital, which purchased directly without a purchasing agent, had the lowest claimed prices, followed by a large professional purchasing agency, a foundation-related purchasing agency, and a general purchasing agency. In addition, the difference between the claimed prices and the maximum allowable prices according to the purchase type was larger in the expensive treatment materials, and in the case of the lower price treatment materials, it tended to converge to the maximum allowable prices. Conclusion: National health insurance spending for therapeutic materials are to be affected by the distribution channels of them. We proposed several ideas to rationalize the expenditure such as classification of therapeutic materials on the basis of price or other criteria.

'협업 네트워크'는 가상기업, 동태적 공급망, 전문가 가상 커뮤니티 등을 포함하는 새로운연구 분야로서 협업 네트워크 조직(CNO)의 생성과 운영에 초점을 둔 모델링 언어가 필요한상황이다. 본 논문은 모델 자체의 표현력과 정보시스템의 구현 용이성을 모두 높인, CNO 대 상의 아키텍처 모델링 언어(CAML)를 제안하기 위한 것이다. CAML은 모델 기반 아키텍처 (MDA)에 입각해서 메타 모델과 도메인 모델을 통합하고 자크만 프레임워크에 입각해서 데이터, 프로세스, 링크, 참여자, 사건, 목적 등의 여러 초점을 통합할 수 있게 한 것이다. 공급망 문제의 모델링과 모델 변경 영향 분석을 통해 CAML의 유효성을 검토하였다.

일본의 관세 및 세관행정은 매우 보수적이었으며 사회안전 및 국민 안전확보와 무역원활화 가운데 사회안전 및 국민안전확보 측면을 강조해 왔으며, 최근에는 지적재산권 침해물품에 대한 문제를 중요한 과제로 인식하고 있다. 이에 반해서 우리나라의 경우는 통관간소화를 추진하는 과정에서 수출입 신고내용과 물품의 일치여부를 검사비율이 현저하게 낮아져 수입업자가 악용할 수 있는 여지를 두고 있다. 이러한 가운데 일본의 관세 및 세관행정의 변화는 우리나라에게 어느 정도 시사점을 제시하고 있다고 보여진다. 따라서 본 논문에서는 일본의 관세 및 세관행정에 대한 변화에 대한 시사점을 도출하고 이러한 일본의 변화에 대한 우리나라의 대응방안을 제시하였다.

In deriving the economic order quantity (EOQ) formula, it is tacitly assumed that the buyer has to pay product price while receiving the product from the supplier. However, as a marketing policy, some suppliers permit a delay in payments to the buyers to increase demand for the product they made. Credit transactions would have a positive effect on both suppliers and buyers. For a supplier who offers trade credit, it is an effective means of price differentiation to increase the demand for the product. Availability of opportunity to delay the payment in buyer effectively reduces the cost of holding stocks and therefore, the buyer has a lot of price options to choose his sales price for a customer. Since the buyer's order is affected by the customer's demand, the problems of determining the sales price and EOQ are interdependent and must be solved simultaneously. From this perspective, this paper evaluates the problem of determining the optimal sales price and EOQ for the buyer at the same time when the supplier allows a delay in payments for the product whose demand is represented as a function that decreases linearly with the sales price. For the analysis, it is also assumed that inventory is exhausted not only by customer's but also by decay.

A power-saving mechanism for smartphone devices is developed by analyzing the features of data that are received from Internet of Things (IoT) sensors devices to optimize the data processing policies. In the proposed GreenIoT architecture for power-saving in IoT, the power saving and feedback mechanism are implemented in the IoT middleware. When the GreenIoT application in the power-saving IoT architecture is launched, IoT devices collect the sensor data and send them to the middleware. After the scanning module in the IoT middleware has received the data, the data are analyzed by a feature evaluation module and a threshold analysis module. Based on the analytical results, the policy decision module processes the data in the device or in the cloud computing environment. The feedback mechanism then records the power consumed and, based on the history of these records, dynamically adjusts the threshold value to increase accuracy. Two smart living applications, a biomedical application and a smart building application, are proposed. Comparisons of data processed in the cloud computing environment show that the power-saving mechanism with IoT architecture reduces the power consumed by these applications by 24% and 9.2%.
