This paper proposes a heuristic optimal solution of multicommodity transportation problem. The proposed algorithm has 3 steps. First the proposed algorithm transforms multicommodity transshipment problem to a general transportation problem, but if the problem is a multicommodity transportation problem, it is not transformed. And the multicommodity is disassembled to a single commodity. Second if it is a multicommodity transportation problem, the algorithm selects the minimum cost according to commodity, on the other hand if it is a multicommodity transshipment problem, the algorithm directly selects the minimum cost based on demand area. And the algorithm assigns carloadings to be satisfied the supply and demand quantity. The algorithm repeats these processes until a given demand quantity is satisfied. Last if it has a condition that is able to reduce the transportation expense, the proposed algorithm controls the assignment quantity of the initial value that got from the step 2. The proposed algorithm was applied to two multicommodity transportation problem and three multicommodity transshipment problem and it got more good result than an existing linear programming method.

Having ahead the Korea-US FfA come into effect by beginning of the 2012, the interest to U.S. trade law has been highly increased. The abuse of U.S. antidumping measures, especially, have been alleged by many developed countries, that's why it need to be studied. For initiating antidumping investigation, the scope of "subject merchandise" has to be determinated. But there is no regulation about the term "subject merchandise(or product under consideration)" on WTO Antidumping Agreement as well as U.S. Antidumping Law. U.S. antidumping law defines domestic like product as "a product that is like, or in the absence of like, most similar in characteristics and uses with, the article subject to an investigation under this title". Thus, the reference point from which the like product analysis begins is "the article subject to an investigation". The Department of Commerce should interpret the subject merchandise in accordance with customary rules, beginning with its ordinary meaning. The note of caution is that the DOC generally exercises 'broad discretion to define and clarify the scope of an antidumping investigation in a manner which reflects the intent of the petition. This paper investigates the survey scope of product in U.S. antidumping law through related regulations and cases. In addition, it was carefully examined because the scope of subject merchandise has effect on antidumping duty order.

This paper is to understand what effects the introduction of IFRS(International Financial Reporting Standard) will have on legacy AIS(Accounting Information System) and how to minimize the problems of that. In order to meet that purpose, we have to recognize the difference between K-GAAP(Korea-Generally Accepted Accounting Principles) and K-IFRS(Korea-International Financial Reporting Standards) first. And then we try to find out what effects the difference between K-GAAP and K-IFRS will have on the legacy AIS. In order to avoid the disorder When K-IFRS will be introduced to the company, new functions have to be added to existing system in proper manner and some existing functions should be changed correctly according to K-IFRS. And CIO(Chief Information Officer) should have to make a careful decision what is the better solution between in-house development and outsourcing for developing new system.

인터넷 경매란 전자상거래 방식의 일종으로, 웹사이트를 통해 사이버거래 장소에서 구매자와 판매자간에 다양한 경매방식을 적용하여 물품의 경쟁매매가 이루어질 수 있도록 하는 서비스이다. 현재 국내외 인터넷 경매 사이트는 경매의 성격 보다 쇼핑몰에 경매를 부과한 형태의 복합적인 특징을 가지고 운용되고 있다. 이로 인해 가격을 기준으로 입찰 참여 및 경매 완료를 진행하기에는, 다소 현실성이 떨어진다는 문제를 내포하고 있다. 따라서, 본 논문은 구매하고자 하는 상품에 대하여 현재 진행 중인 경매의 상황을 예측 및 판단하여 구매자에게 경매 정보를 제공함으로써 합리적으로 물품의 구매를 도울 수 있는 알고리즘을 제시하고, 예측 알고리즘을 구현한 경매 예측 에이전트와 사용자의 패턴을 기록하고 상품구매, 입찰 등을 대리하는 에이전트들로 구성되는 에이전트 기반 경매 시스템을 소개한다.

Since the late 1990s, mixed-use apartment, armed with high qualities and large scales with a high ratio of TFA(Total Floor Area) have been continuously provided accommodating exclusive community facilities along with high-tech securities, not to mention excellent skyline view. However, especially in mid-small cities, there have been only a few supplies. As a result, none of the mixed-use housing provided by high-end brands has ever been built in non-metropolitan area. But constructors couldn't plan the projects which aims to build the mixed-use apartment in local city, because they couldn't get the basic data or advanced research for feasibility analysis. Therefore, to suggest the useful price for mixed-use apartment supply project of local city, the PSM(Price Sensitivity Method) widely used for determining the price preferences as a market research tools has been applied. As analysis results, the estimated price of mixed-use apartment is 10.8% higher than general apartment, and mixed-use apartment has lower price sensitivity than general apartment. As price determinants, the age, education level and family size influence on UTP in significant level. It is expected that these research findings can be applied for establishing the solid marketing strategy of mixed-use apartment development project in local city.

The purpose of this study is to explore the convergence sector of the spatial information industry based on the business transaction data of spatial information companies and to predict the market size of the industry using the Seemingly Unrelated Regression(SUR) model. The convergence part of spatial information industry, which cannot be identified in the Spatial Data Industry Survey, was analyzed by exploring keywords related to spatial information using the business DB of Korea Enterprise Data (2010-2019). The convergence of spatial information businesses mainly appeared in the business relationship between the value chain between Seoul and Gyeonggi Province. The convergence business has the largest sales in the value chain 2 (utilization, service) & 3 (convergence), and also the convergence in the value chain 1 (production, construction) & 2, 2 & 3 stages has doubled in 2019 compared to 2010. In 2019, the total sales of the spatial information industry based on the Statistical Korea were announced at about 8 trillion won, but in this study, the total sales of the spatial information industry were estimated at 28 trillion won considering convergence activities. Finally, when scenario 1 (0.38% population growth, 2020-2024) and 0.07% (2026-2030) were applied using the SUR model to predict the expected market size of the industry, sales decreased by -0.37% to 0.069% in 2025 and 2030 by respectively. When scenario 2 (average wage growth 1.2%) was applied during the same period, sales in the industry increased by 2.326% to 12.185%. In other words, the sales in the spatial information industry depends on Labor, Total Factor Productivity, and Capital Productivity so it is necessary to additional research on policy development and alternatives of enhancing each productivity.

As information technology of constructional area develops recently, web-based on-line system is rapidly increasing to provide information on diverse constructional materials so as to enhance productivity of constructional business and to reduce cost. Since the constructional materials information provided by these systems, i.e., quality, specification, etc are not standardized, however, the staffs on the constructional site suffer considerable difficulties in using materials information when acquiring information on specific materials, e.g., using diverse information systems or repeating similar jobs. Thus, this research typified information items of constructional materials on the basis of GDAS and designed multi system model to control integrated information on constructional materials. This system can efficiently control and utilize materials information by supporting automatic classification of constructional materials to which OmniClass Part-22 and UNSPSC are applied, conditional complex retrieval of materials information, real-time automatic embodiment of electronic catalog and retrieving/controlling RFID.
