After being kept in bonded areas and bonded logistics warehouses, the level of information sharing and progress confirmation on the process until the cargo is released is insufficient, resulting in disputes and legal disputes related to unauthorized and illegal delivery of cargo. This study attempted to present the introduction of standard electronic documents as a way to solve problems such as delivery practices raised in the delivery of existing imported cargo and legal disputes related to unauthorized illegal delivery among import-related entities. The service provider who manages the bonded warehouse/logistics center in the hinterland of Busan New Port and the shipper service user who use the service were classified into two groups, and a survey was conducted to analyze the difference in perception between the two groups. As a result of the analysis, both groups judged that the introduction of standard electronic documents was necessary, and showed high expected effects in preventing and reducing erroneous shipments and preventing and improving unauthorized and illegal shipments. Discussions between related organizations, related parties, and subjects are needed first to introduce standard electronic documents of the entry and warehouse management system, and the actual participation of related entities such as service providers and service users will play a very important role in establishing the system.

Port industry has achieved a remarkable growth with a help from increase in container shipment and above all, transshipment that reflects international competitive power of Port industry amounts to 36% of the national harbor shipment. Therefore, this study speculates the impact of Port industry on national economy using the inter-industry relation table. As it considers the reason why international competitive power in Port facilities decreased as absence of investment, it is to present an effective investment plan for Port industry. Though Port industry as one of main national key industries play an important role in production of national economy, it has been evaluated as having relatively less importance. And when Port industry is managed independently, relying on foreign countries without improvement, price increase due to improper agreement of foreign enterprises and problems relating to securing safe transportational vehicles will have tremendous impact on national economy. And they should try to create added-value and support re-export of the exported and imported shipment through their processing and packaging by making Port zones bonded area. production of national economy, it has been evaluated as having relatively less importance.

This study is to clarify regional structure and connection of international physical distribution through clearance depot of Cheongju customs of inland location. The trade of clearance depot of Cheongju customs industrial characteristics reflects of territorial hinterland. As origins and destinations of freight as exports and imports region, territories of Cheongju customs trade mainly with Japan, China, and USA. Origin and destination of freight of Cheongju customs territory are hinterland and foreland of Incheon International Airport and Busan port. In case of export, foreland of Busan port is board, and in case of import, the hinterlands of Incheon International Airport and Busan port are similar. Clearance depot of inland-located Cheongju is construct by the advantages of rapidness and inexpensive cost. And the kind of freight and system of physical distribution of each enterprise show different characteristics. For each export and import freight, each shipper corporation has its own physical distribution system, and structure of international distribution is classified into export pattern of bonded industry and bonded warehouse. Again the patterns of bonded warehouse are distinguished free on board price system with division of labor in base of production in overseas, free on board price system, and cost-insurance-freight with division of labor in base of production in overseas. These Phenomena are caused by transaction between headquarter and its overseas corporation, initiative freight handling of export corporation, choice of inexpensive cost, and international convention.

A flat-jointed bonded-particle model (BPM) has been proved to be an effective tool for simulating mechanical behaviours of intact rocks. However, the tedious and time-consuming calibration procedure imposes restrictions on its widespread application. In this study, a systematic approach is proposed for simplifying the calibration procedure. The initial relationships between the microscopic, constitutive parameters and macro-mechanical rock properties are firstly determined through dimensionless analysis. Then, sensitivity analyses and regression analyses are conducted to quantify the relationships, using results from numerical simulations. Finally, four examples are used to demonstrate the effectiveness and robustness of the proposed systematic approach for the calibration procedure of BPMs.

Although the port distripark concept and its development policy have been introduced since almost twenty years, there is no visible results of the policy. Specifically, the level of value-added logistics using transhipment cargo is too low. In this paper, we mainly focus on the causes of the policy failure of port distripark's value added activities in terms of conceptual as well as practical or functional. Definitely, the study reviews the concept of port distripark compared to industrial park or bonded factory. The study also analyzes the differentiation of port distripark and port hinterland. The study generats that the problem or error that may occur when port hinterland is identified with the port distripark. Last but not least, the limitations of value added logistics is generated on the study. We examined in depth whether the already well known value added activity of port distripark is really activities that add 'value'.

In this study, for purpose of searching for measures to lower the logistics costs which is one of the most difficulties for the small-medium sized manufacturers in Pusan and Kimhae, those manufacturers were surveyed with questionnaire about the facts in the export logistics costs, difficulties related to the costs, and measures they thought for lowering the cost. Taking account of findings from the survey, the comprehensive measures of saving the export logistics costs were to be proposed. In the surveyed manufacturers, the problems they thought over export logistics costs lied in short logistics information and transportation-related difficulties in cargo and distribution, insufficient standardization in packaging and the shortage of material handling equipments in unloading. In transportation, frequent non-fulfillment of in-time shipment, cost increase including over consumption of transportation time due to traffic jam, and the biased heavy use of inland transportation were pointed out as problems. In customs clearance, logistics information, and marine insurance, addressed were complexity in custom clearance and bonded transportation procedures, and the shortage of software and hardware to construct logistics information system.
