The multisector model is designed to analyze and forecast structural change in industrial output, employment, capital and relative price as well as macroeconomic change in aggregate income, interest rate, etc. This model has 25 industrial sectors, containing about 1,300 equations. Therefore, this model is characterized by detailed structural disaggregation at the sectoral level. Individual industries are based on many of the economic relationships in the model. This is what distinguishes a multisector model from a macroeconomic model. Each industry is a behavioral agent in the model for industrial investment, employment, prices, wages, and intermediate demand. The strength of the model lies in the simulating the interactions between different industries. The result of its simulation will be introduced in the next paper. In this paper, we only introduce the structure of the multisector model and the coefficients of the equations. The multisector model is a dynamic model-that is, it solves year by year into the future using its own solutions for earlier years. The development of a dynamic, year-by-year solution allows us to combine the change in structure with a consideration of the dynamic adjustment required. These dynamics have obvious advantages in the use of the multisector model for industrial planning. The multisector model is a medium-term and long-term model. Whereas a short-term model can taken the labor supply and capital stock as given, a long-term model must acknowledge that these are determined endogenously. Changes in the medium-term can be analyzed in the context of long-term structural changes. The structure of this model can be summarized as follow. The difference in domestic and world prices affects industrial structure and the pattern of international trade; domestic output and factor price affect factor demand; factor demand and factor price affect industrial income; industrial income and relative price affect industrial consumption. Technical progress, as measured in terms of total factor productivity and relative price affect input-output coefficients; input-output coefficients and relative price determine the industrial input cost; input cost and import price determine domestic price. The differences in productivity and wage growth among different industries affect the relative price.

The Uniform Customs and Practice for Documentary Credits (UCP) is a set of rules on the issuance and use of letters of credit. Historically, the commercial parties, particularly banks, have developed the techniques and methods for handling letters of credit in international trade finance. This practice has been standardized by the ICC (International Chamber of Commerce) by publishing the UCP in 1933 and subsequently updating it throughout the years. The ICC has developed and moulded the UCP by regular revisions, the current version being the UCP600. This latest version, called the UCP600, formally commenced on 1 July 2007. During the revision process, notice was taken of the considerable work that had been completed in creating the International Standard Banking Practice for the Examination of Documents under Documentary Credits (ISBP), ICC Publication 745. This publication has evolved into a necessary companion to the UCP for determining compliance of documents with the terms of letters of credit. It is the expectation of the Drafting Group and the Banking Commission that the application of the principles contained in the ISBP, including subsequent revisions thereof, will continue during the time UCP 600 is in force. This paper focuses on documents including various certificates, Packing List, Weight List, Beneficiary's Certificate, Analysiis, Inspection, Health, Phytosanitary, Quantity and Quality Certificates, Courier Receipts, Shipping Advice etc. and suggests some implications in the field.

The level of ICT in the country affects economic performance as a basic infrastructure that has a significant impact on the competitiveness of the country. With the proliferation of globalization, ICT-related economic activities such as electronic trade are becoming more active, and the importance of ICT in the country is increasing. This study sought to analyze the impact of ICT level on the economic performance of the nation by subdividing it into three dimensions: accessibility, usage, and utilization skill. In particular, we sought to find ways to effectively resolve the digital divide between developed and developing countries by analyzing the difference in economic impact of ICT level. Furthermore, we tried to verify whether the government regulation and firm's nature of competitive advantage in the international markets play a moderating role in the economic impacts of ICT in the country. As a result of panel analysis with data collected from ITU, WEF and World bank national ICT level has consistently significant influence on economic growth in terms of access and usage. In addition, it was confirmed that the competitive advantage of companies in developed countries and the government regulation in developing countries have a significant moderating effect on the relationship between ICT level and economic growth.

Human history shows diverse strategies for survival and prosperity. This study introduces the concept of the expansion of wealth as a key to explain choice and behavior of political entities. American scholar, -Bruce Bueno de Mesquita-, offers theoretical grounds for this concept in that the cores of selectorate theory is settled. The political entity consists of two groups, -the winning coalition that has power to replace leader and non-winning coalition that has not. Leaders implement policies serving for the welfare of winning coalition in return for their loyalty. Both internal problems caused by demographic changes and external ones of climate changes, epidemic disease, or invasion compel leader and winning coalition to adopt policies of expansion that they believe may lead to the acquisition of wealth needed to counter those problems. The process starts by occupying one spot where other entities reside and then connecting it to its own. The line between spots functions as a foothold to form a new line to other spots. By repeating this process, a space is created in which new laws and orders are instated. In the early stage of expansion, war is hardly avoidable. Once finished successfully, the political circumstance tilts to encourage economic activities in order to generate national revenues to strengthen political power of winning coalition. However, as scale of economic activities grows, so does political power of civic classes in production and trade. To gain financial support required to run the political entity, delegation of power or bestowing autonomy to non-winning coalition is inevitable. Thus, expansion is not the ultimate solution, only to prolong the political survival if succeed. Maritime power came to attractive option when overland expansion had become obstructed. It offered much greater advantages in terms of political risks and financial burdens in exploring new regions of precious commodities than overland expansion. Each political entity around world have been, for the first time in human history, connected by maritime means since 15th century. It is worthy of noting that land conditions propelled people out to sea. Political and economic situations created opportunities to exploit geographical position in pursuit of wealth. In the 21st century, we witness the operation of international winning coalition that presides over the rules of expansion. Competing for market is synonymous to the expansion in this era, the cause and aim of it has not been changed though. Energy and dollars are key factors of expansion since the end of the 2nd world war. No matter what the forms and conditions change, naval power is still the most relevant means for expansion as it retains unique characters of maneuver, flexibility, continuity, display and projection of power. The strategy for using naval power should be in line with two different approaches for expansion: Approaches to the international winning coalition by making contribution to world order, and approaches to the non-international winning coalition by enhancing military diplomatic activities. The former will serve our share of winning coalition while the latter will open chances to acquire further prosperity.

The continuous deployment of Urban Traffic Information System (UTIS) in Korea has increased the need for developing more practical applications utilizing the standard functions of UTIS facilities installed on urban arterials beyond its basic applications like gathering traffic data and providing traffic information. The UTIS-based bus signal priority may be one of UTIS-based applications meeting such demands. However, the studies on BSP have not been sufficient for actual field deployment in terms of theories and algorithms so that there have been few actual installations on real urban arterials. Thus, this study was aimed at developing a UTIS-based bus priority signal system and evaluating its effectiveness through a field study. To this end, this study presents the system development processes by dividing the UTIS-based bus priority signal system into hardware and software. In addition, the positive effectiveness of the UTIS-based bus priority signal system was verified through a field application test which was conducted at Gyeonggi Global Trade High School intersection.

Over the last 10 years, the fight against occupational diseases of semiconductor workers led by SHARPS(the Supporters for the Health And Rights of People in the Semiconductor industry, NGO) has accomplished considerable achievements, especially in the legal and institutional aspects. First, the court and the government accepted the claims that 24 injured workers respectively filed, recognizing their 10 types of diseases as occupational illness. The court not only expanded the list of work places and diseases that it recognized, but also presented more progressive logic of recognition. The most remarkable achievement among them is the case ruled by the Supreme court in July, 2017. In terms of 'worker's right to know', which is the most important factor in preventing occupational diseases, there have been significant legislative bills, court rulings and government guidelines. The revised bill of the Industrial Safety and Health Act to strengthen workers' rights to know and to introduce the pre-review system on trade secret is currently under review by the National Assembly. The court recently ruled that the government should disclose its inspection results on safety and health management at semiconductor factories. The ministry of labor has drawn up internal guidelines to more actively open its safety and health data to public. This study looks over recent developments in such rulings, bills and guidelines and then, analyzes their implications, laying the groundwork for future actions for worker health in the electronic industry.

It is essential to connect the railroads between South and North Korea in order to the implementation of the Eurasia initiatives and prepare for the normalization of the economic cooperation between south and north Korea as well as the unification. This study provides the strategy to establish the rail logistics network for the normalized trades between south and north Korea, and the accommodation of the logistics demands to China and Russia. The alternative routes were designated and the costs for the rehabilitation were estimated, and suggested the priority for the investment. The Trans-China Rail is prior to the Trans-Siberia Rail in terms of the utility for the logistics and the political value. In connection to the TSR, it is desirable to pass the Seoul-Gyeonggi area where the demand is greater than the other area. This route is limited by the restriction in the capacity, then the Gyeonggi Ring Rail route may be necessary.

There has been a need to update the current Codex nutrient reference values (NRVs) which had been established following the Helsinki Consultation in 1988. The main purposes of NRVs are to help consumers compare the nutrient content of different food products and estimate the usefulness of a food product in terms of its percentage contribution to the overall healthful diets. The establishment of Codex NRVs for labelling purposes is intended to facilitate the goals of protecting consumers' health and ensuring fair practices in food trade. When revising the Codex NRVs several issues are needed to discussed, which are: 1) Consideration of population groups whether to have one set of NRVs for general population or to have several sets of NRVs for each population groups, 2) Determination of scope of nutrients such as what nutrients to include and what reference values to choose and 3) Development of principles for establishing NRVs such as the selection of suitable reference values among many including recommended intake/recommended dietary allowances, estimated average requirement and upper levels to extract NRVs. This paper will discuss the above issues and the inputs and efforts that the Korean Nutrition Society had put into to carry out the project, "International Collaboration on the Revision and Addition of the Codex Nutrient Reference Values for Food Labelling Purposes," and to ascertain relevant scientific principles and evidences that are utilized for establishment and revision of the Codex NRVs.

Piracy is the enemy of the human race. Pirates commit acts of murder, robbery, plunder or other villainous deeds at sea, cruelly against humanity. The Republic of Korea(ROK), as a big maritime country, is obliged to suppress piracy under international treaties it ratified, including the UN Convention on the Law of the Sea and the two 1988 Conventions against maritime terrorism The Korean government is recently taking a positive attitude towards the regional cooperation which is necessary for the suppression of piracy in the waters of Southeast Asia In spite of the effects of international cooperation to prevent piracy, it is recently on an increasing trend every year. Such circumstances may have a bad effect on the sound development of world economy by means of trade at sea as well as treat to the safety of crews and safe operation of ships. This paper aims to suggest the countermeasures against piracy in terms of criminal law, civil law and international law in order to secure safe operation of vessels at sea.
