The modal spilt for road has been increased, but, for railroad it has been decreased from 17.2%(1990) to 6.3%(2006). It is important to study on improving competition for railroad transportation so that freight transport industry for railroad which is getting to decrease in Korea will be increased. The objective of this study is to analyze the competitiveness of railroad transport compared with road by providing a high-speed railway. The indicators representing the competitiveness of railroad transport are determined. The main influenced factors for mode choice include transport cost, transport time, level of service. Precisely, three commodities type, container, cement, steel, are analyzed.

This study focuses on the analysis of purchased items' relationship occurred by consumers' purchasing behavior observed in on-line shopping mall based on social network analysis. In order to find relational characteristics of each item for establishing marketing strategy, we apply three definitions of centrality in network, which are degree centrality, betweenness centrality, and closeness centrality in the purchased items' network. Thus, the research results provide the criteria for selection of market segmentation variables. Furthermore, the details of case has been introduced to validate the analyzed results in terms of marketing strategy, and supporting evidences are provided accordingly.

There are index adjustment method and item adjustment method in estimation methods for price fluctuation rate of public constructions. A relevant regulation has put item adjustment method as a principle, but in most construction, contract sum adjustment has been made by index adjustment method. Hence, this study, by figuring out width and causes of the gap between index adjustment method and item adjustment method through direct comparative analysis, solved inequality caused by difference between them and suggested a rational way against irrationality of each method. For building operations of public housing construction, a detailed fluctuation rate by index adjustment method and item adjustment method of construction cost elements of the same construction, that is, direct material cost, direct labor cost and historical construction cost was estimated to analyze difference between two adjustments and establish its cause. Across the analysis, it was found that fluctuation rate by item adjustment method was estimated lower than that by index adjustment method and difference between methods for estimating fluctuation rate of quotation unit price and application of index unrelated to construction type and construction nature are main causes of the difference. This study has a significance in that, for smooth contract sum adjustment between contracting parties, it practically proved the real difference between adjustment methods by conducting comparative analysis of the difference in direct correspondence way.

The survey guideline of forest products statistics suggests a certain type of standard to aggregate production amount of each item such as dry bracken, raw dates, cracked nuts, It does not, however, give any information about transition ratios, which would apply to convert weights of fresh bracken into dry one, or cracked nuts into the non-cracked. This has been one of the main factors which would make the statistics unreliable. The purpose of this study is to examine the aggregation realities and to put forward some proposals to improve forest products statistics with transition ratios. Targets of this study are 10 forest products that are strongly related to the mentioned problems. With the calculated transition ratios and some assumptions the changing rate of the official statistics of 2004 production amounts ranged from -41% to 474% for the 10 subjects. The suggested figures for transitions are based only on one-year analysis results. Therefore more periods are required to improve the accuracy and the reliability, and this study would be a good starting point.

Regional specialty products should be representative of the regional characteristics for a long time, this was not done for geographical research. This study examines current the regional specialty products on 12 web-site of the cities counties in 2013 and the products registered on the Tosan(土産) category from old Jiriji(古地理誌) in Chungcheongbuk-do. Futhermore, the study analyzed periodical change and regional distribution characteristics of regional specialty products. Major findings are as Follows. First, current the regional specialty products types are 4 products(crops, marine products, forest products, livestock products) and 3 manufactures (processed food, handicraft, cosmetic products). Among the regional specialty products, various crops and processed food were distributed in all the regions. Second, the traditional products types are 5 products(crops, marine products, forest products, livestock products, mineral products) and 1 manufactures(handicraft) that registered on the old Jiriji in the Joseon Dynasty period. The jujube, ginseng and honey were cultivated in the most regions. Third, the traditional products types are 4 products except for marine products and 1 manufactures(handicraft) that registered on the old Jiriji in the period of Japanese colonial rule. Its total item numbers of the regional specialty products are greatly decreased, but items of handicraft relatively increased in the Danyang and Goesan regions. Finally, regional analyzing of current local items shows that there are only a few regional specialty products(18 items) that have historical traditionality.

앞으로의 국제사료곡물 시세 및 국내 주요 단미사료 시세에 큰 변동은 없을 것 같다. 만약 곡물 시세를 변동시킬 만한 요인이 있다면 현재 강세를 보이고 있는 강류사료 가격의 여하와 소련의 구매량과 구매시기, 미국의 주산지 기상조건 및 그 외 곡물 수출국가의 수출여력과 수요국가의 수요도 여하에 따라 결정지어 질 것으로 전망된다. 그리고 관세제도의 변경실시로 옥수수, 수수, 타피오카 이외의 품목은 관세가 부과되므로 특히 고열량사료인 우지 등의 수입이 어렵게 되었다. 또 배합사료 가격안정기금 확보를 위한 수입사료 부담금적립 등의 문제가 있겠으나 전반적으로 밝은 전망이다. 이러한 때를 놓치지 말고 우리 축산인 모두가 서로 협력하여 축산업의 안정적 발전을 위하여 총매진해야 겠다.

본 논문은 유비쿼터스 사회의 도래에 대비하여 국내 소출력 무선 산업의 현황파악을 목적으로 2006년도 상반기에 실시한 설문조사 결과를 제시하고 있다. 조사된 주요결과에 의하면, 국내 소출력 시장에서는 중소업체(평균종업원 수: 14명)가 대부분 기기를 제조하고 있지만, 무선마이크 또는 모형비행기 등의 일부 품목에서는 수입제품이 큰 비중을 차지하고 있으며, 제도개선 측면에서는 인증절차의 단순화에 대한 요구가 많았다.
