컨테이너 보안 장치(CSD)는 컨테이너의 문 안에 장착되어 센서를 통해 컨테이너의 문이 비정상적으로 열리는 것을 탐지하는 장치다. 이러한 CSD 장치는 컨테이너의 보안성을 제공하는 장치이기 때문에 도청이나 위조와 같은 공격에 안전해야할 뿐만 아니라 복제 되어서도 안된다. 만약 복제된 CSD를 탐지할 수 없다면, CSD는 공격자에 의해 불법적으로 복제되어 정상적인 목적과는 다른 용도로 사용되어 질 수 있다. 본 논문에서는 이러한 복제된 CSD를 탐지하기 위한 정책 기반 복제 탐지 메커니즘을 제안한다. 또한 실제 구현 결과를 통해 제안하는 기법을 검증 및 평가한다.

In this paper, we consider multi-item inventory management. When managing a multi-item inventory, we coordinate replenishment orders of items supplied by the same supplier. The associated problem is called the joint replenishment problem (JRP). One often-used approach to the JRP is to apply a can-order policy. Under a can-order policy, some items are re-ordered when their inventory level drops to or below their re-order level, and any other item with an inventory level at or below its can-order level can be included in this order. In the present paper, we propose a method for finding the optimal parameter of a can-order policy, the can-order level, for each item in a lost-sales model. The main objectives in our model are minimizing the number of ordering, inventory, and shortage (i.e., lost-sales) respectively, compared with the conventional JRP, in which the objective is to minimize total cost. In order to solve this multi-objective optimization problem, we apply a genetic algorithm. In a numerical experiment using actual shipment data, we simulate the proposed model and compare the results with those of other methods.

The Customs Administration, unlike other administrative service, should respond to constantly changing external environment. The Customs has to actively adapt itself to government policy changes, economic changes and international environment changes to facilitate the flow of trade logistics and maintain trading relations wi th other countries. The purpose of this paper is to explain policy directions of the Korea Customs Service which enforces various policies related to tariff and non-tariff barrier elimination for the trade liberalization while the Korean government is pursuing FTAs on a multi-track basis. This paper aims to seek ways to apply FTA policies to the Korean society and economy in a smooth manner. First of all, this paper examines changes in Customs administration brought by the proliferation of FTAs to such areas as FTA negotiations, import/export management, duties and taxes collection, drawback reduction/exempt ion of duty application area of preferential tariff rate and country of origin management. Then, the paper sets FTA missions of "supporting Customs Administration to lead the new trend of free trade environment" after analyzing the environment changes. To achieve the FTA mission mentioned above, the KCS designated 4 strategies and 40 implementation tasks. The 4 strategies are named "4C Strategies" taking initial letters from Client-oriented, Customized procedures, Cooperation and Constitution. "4C" also refers to Foresee(strategies to foresee the successful establishment of FTA policies) or For C(Customer or Customs). The KCS will continue to create new tasks through various channels and monitor their implementation process, and to help FTA regime successfully take root in Korea.

This study is to develop a performance analysis model for SMEs.Based on similar performance indicators through previous studies, performance indicators for SMEs were rewritten.Through the Korean Journal Citation Index (KCI), 75 related data were classified and a comprehensive SME performance analysis model was developed.Performance analysis was divided into two axes and classified into tables.The horizontal axis is the spatial performance range, which is divided into three areas: performance management by department/function, integrated performance management for the entire organization, and governance performance management requiring policy feedback. The vertical axis is subdivided into short-term, mid-term, and long-term by time and growth stage, and is divided into three parts: technical performance according to technological input, economic performance as organizational performance, and social performance for policy utilization. Then, performance indicators were mapped to each column. As a result of the survey, 28% of technical performance was analyzed as a result of frequency analysis, and performance indicators were organized into five categories: IT, R&D, certification, patent, and innovation. Economic performance was divided into 29%, BSC, HRD, logistics, production quality management, financial support, asset management, etc. 6 categories, social performance 43%, ESG, marketing, export, policy support, consulting, cooperation, etc. 7 categories.Limitations of the study include the narrowness of the survey that derived only performance indicators despite being a meta-analysis, and the performance model was mapped and classified according to growth stage and support period.however Insufficiency of validity due to lack of evidence, performance indicators were developed, but there were limitations in utilization for practical use.

Purpose - The purpose of this paper is to improve last mile delivery capability and ensure customers' satisfaction by approaching an analytic hierarchy process(AHP) and identifying criteria framework to determine locations of last mile delivery centre(LMDC). Research design, data, and methodology - Traffic congestion and emission policy in cities are barriers of last mile delivery in dense areas. The urban consolidation centre(UCC) cannot increase last mile delivery efficiency in dense cities because of their space and traffic limitation. In this paper, we develop a case to improve last mile delivery efficiency and to ensure customers' satisfaction by concentrating on LMDC. In addition, AHP has been applied to identify criteria framework and determine LMDC locations. The weighted priorities are derived from parcel delivery industry experts and have been calculated using Expert Choice software. Results - The framework criteria have assisted decision makers to place LMDC in a dense area to enhance customer's satisfaction with last mile delivery service. Conclusions - AHP has provided ranking framework criteria of LMDC potential for parcel delivery industry. The LMDC helps by improving last mile delivery efficiency to final destination amids conditions of CO₂ emissions, traffic congestion, and pollution problems. It especially concerns delivery service activities when delivering parcels to customers rather than UCC.

The purpose of this study is to measure the productivity of fisheries in China's coastal areas (including inland and marine fisheries) and to analyze the factors influencing the development of fishery economy in each province by comparing regional differences. The input indicators used for efficiency analysis are fish farms, ships and staff numbers, and the output indicators are fish catch and net income. In this paper, we used six years of data from 2013-2018 and DEA-Malmquist index was used to analyze the efficiency of coastal fisheries production in 11 areas of China's coast. According to the analysis from 2013 to 2018, the fishery output efficiency in China's coastal areas has improved to some extent, but most provinces and regions are characterized by technological progress, and the technological efficiency still needs to be further improved. The conclusion can provide reference for the development planning and policy measures of regional fishery industry in China's coastal areas.

This study focuses on analyzing the economic effects and probes the necessity of establishing a customs free zone at the Port of Busan. It first considers the economic effects of establishing a customs free zone at the Port of Busan, then suggests policy prescriptions for introducing and operating the free zone system and improving the logistics functions of the Port. The timeline of this study is focused on 2007, when all of Busan Port will operate as a customs free zone and the first stage of the New Busan Port and distribution parks will be built and opened for operation. The regression analysis, which was conducted using the inter-industry relations table(input-output table data), provided a quantitative prediction on the effects of making Busan Port into a customs free zone. Regarding the impact of a free zone system on the domestic and regional economy, this research found that the impact of a customs free zone on domestic industries and the regional economy once the customs free zone is established throughout all of Busan Port would be highly positive. The positive economic effects on the domestic and Busan regional economy might be further strengthened if the value-added logistics function of Busan Port could be supplemented by effective linking to the hinterlands.
