SCM 경쟁력 재고는 기업 내의 부문별 또는 개별기업 내부의 한정된 개선 노력이 외부의 부문 또는 기업에서의 활동과 연계되어 전체의 최적화가 되지 않으면 그 성과가 극히 제한적일 수 밖에 없다. 따라서 히든 코스트(hidden cost)의 발견 및 유통물류의 최적화에 박차를 가하는 것이 현실이다. 본 연구는 순 물류로 진행한 유통 경로 상에서 만약 역 물류가 발생할 경우 순물류 비용이외 공차(empty driving)로 인한 역물류의 히든 코스트를 최소화하는 모형을 통해 물류이익을 최대화 할 수 있는 방안을 찾기 위해 노력하며 결국 순물류와 역물류상의 유통상의 비용과 이익의 쌍대성에 기초하여 Pull, Push 시스템을 이용한 최적 시스템 모델화를 수행하여 효율적인 물류비용 산정의 방법을 모색한다.

The Korean logistics industry has grown with the development of domestic industries. The industry plays an important role in national and regional economic growth, and the government has continued policy efforts to foster the industry. This study analyzes the competitiveness of the regional logistics industry and its contribution to the regional economy. Location coefficients are used to analyze local specialization in each logistics industry. The value-added rate, GDP contribution, value-added induction coefficient, and net value-added income of regional logistics industries are analyzed using a regional input-output table. As a result, the logistics industry is found to have net value-added income and competitiveness in some regions, and there is no relationship between the location coefficient and the value-added contribution of the regional logistics industry. Seoul, Incheon, Gyeonggi, Busan, and Jeju have the competitiveness of each logistics industry. In addition, we identified the regions where the logistics infrastructure is well developed and those in which it needs to be supported. The regions where the logistics industry has developed require policies for making high value-added by logistics activity, and regions with insufficient growth need to support the development of the logistics industry by investing human resources and capital that can meet the local demand.

Since 2000, e-commerce has been increased continuously in its quantity and quality. The growth of e-commerce has resulted in some diversities of distribution channels, and its characteristics of not-spot trading and limited market scale has urged the on-line market to play a role of assistance to off-line market. e-Commerce causes not only the flow of forward logistics, but also that of reverse logistics with every purchasing, which is a very critical factor to hesitate for consumers to purchase the products as well as increase the price of the products. Concern about the reverse logistics by sellers and buyers influences the level of price and purchasing activity of consumers. This study firstly is to lift the awareness of the efficient control of reverse logistics with reviewing the recent change of logistics environment and phenomena of reverse logistics. Secondly we find the factors generating the reverse logistics and look into its questions, and thirdly offer not only the ways to minimize the phenomena of reverse logistics, but also a efficient control system for reverse logistics. We additionally aim to contribute to prevent the price of the products from rising and raise the customers' satisfaction through minimizing the phase of reverse logistics.

The Hunchun area is the only development and opening line in Jilin Province and the Changchun-Jilin-Tumen Developmental Plan area, and as a hub area for regional logistics, promoting the logistics competitiveness of the Hunchun area is an important factor in promoting economic development in the Northeast region. The purpose of this study is to derive the factors for activating logistics competitiveness in Hunchun area by applying SWOT analysis and to present them to policy-makers by drawing priority of factors for promoting logistics competitiveness in Hunchun area through AHP survey of Chinese and Korean logistics experts. According to the analysis, the weighting was high in order of opportunity factors and strength factors, and the priority was high in order of factors such as promotion and expansion of One Belt, One Road policies, active support through national policies, construction of international logistics center cities, construction of logistics centers, and supply of bulk cargo. Finally, from a comprehensive perspective, this study presented policy implications such as SO Strategy (Strength-Occupancy Strategy) and ST Strategy (Strength-War Strategy) focusing on the strengths of the Hunchun Region for the strategy of strengthening the logistics competitiveness of the Hunchun area.

This research is aimed to identify the building factors and deriving the importance of each factor for establishing the smart distribution center in the fourth industrial revolution era. The research methodology used CFPR(Consistent Fuzzy Preference Relations) to effectively extract expert knowledge. Research has shown as principle factors that "Service" is the first factor to be considered as 0.271, followed by "Infra(Warehouse)"(0.254), "Information System"(0.247), and "Equipment"(0.228). And as detailed factors, "Reliability" showed the highest importance as 0.091, followed "Visibility of Information System"(0.076), "Space Advancement"(0.075), "Location"(0.074) and "Satisfaction of service"(0.073). This study has implications in that it has presented an establishment direction for the smart distribution center.

Recently, the rankings of Korean container ports in terms of container handling cargo volume were plunged down due to the emerging Chinese ports. The efficient container ports strategies which increase container port competitiveness were requested. In this respect, it is urgently required to draw out constituent factors for Port Logistics, weigh these factors, and finally focus on improving the suggested factors. The aim of this paper is to evaluate weight and priority values for 'inner consisted factors' and 'outer requested factors' of port logistics by using the AHP(Analytic Hierarchy Process) method. As for the analysis regarding the inner consisted factors, the results were shown as follows: a storage and handling system (0.288) as the first rank; an information system of port logistics (0.210) as the second rank; an inland intermodal system (0.189) as the third rank; a ship's entering and departuring system (0.184) as the fourth rank, and a ship's berthing system (0.129) as the fifth rank. In terms of analysis regarding outer requested factors, the results came out as follows: a logistics cost (0.360) as the first rank; a port service (0.128) as the second rank; a connectivity (0.118) as the third rank; a hinterland condition (0.116) as the fourth rank; an convenience (0.106) as the fifth rank; a regional center (0.095) as the sixth rank, and an availability (0.077) as the seventh rank. For analyzing the priorities changes in constituent factors, the comparison of results between the year 2007 and the year 2011 was done. As the results, among inner consisted factors, 'information system of port logistics' was ranked first in the year 2007 while 'a storage and handling system' became the most important factor in the year 2011. Among the inner consisted factors, however, the logistics cost was the important factor in 2007 and 2011, respectively.

To provide scientific information for processing of value-added products from onion, volatile flavor compounds were compared in onions harvested in 6 regions, such as Muan (Jeonnam), Buan (Jeonbuk), Andong (Gyeongbuk), and 3 regions of Gyeongnam around Changnyeong (Yueo, Jangma, Seongsan). A total of 51 compounds were detected in samples by solid phase microextraction (SPME)/GC/MSD and they consisted mainly of sulfur-containing compounds (20), aldehydes (4), ketones (5), esters (11), aromatic hydrocarbons (4), nitrogen containing compounds (2), and miscellaneous compounds (5). The sulfur-containing compounds were the major compounds with ranges of $62.6{\sim}80.3%$ of total volatiles, regardless of harvested regions. The amounts of 5 sulfur containing compounds known as having antioxidant activity (2,4-, 2,5-dimetylthiophene, 2-vinyl-1,3-dithiane, 5-methoxy thiazole, and 3,5-diethyl-1,2,4-trithiolane) were the highest in Andong and followed by Yueo, Jangma, Buan, Seongsan, and Muan. However, onions from Buan region had the highest amounts of 5 sulfur-containing compounds known as having anticarcinogenic activity ((Z)-, (E)-methyl propenyl disulfide, (Z)-, (E)-propenyl propyl disulfide, and di-2-propenyl disulfide), followed by Yueo, Andong, Jangma, Seongsan, and Muan.
