  • The purpose of this paper is to study the possibility of practical use of gasoline-methanol mixed fuel as an alternative fuel of gasoline engines in the light of engine performances and harmful exhaust emissions as well as mixings and separations of the mixed fuels. When the methanol of 99.8% purity is mixed with super or regular gasoline available on the market today, the experimental results obtained without modifying carburetor in this study are as follows; 1.The separation ratio depends upon the gasoline-methanol mixing ratio only, regardless of fuel temperature and fuel additives for preventing separation of phase. 2.The critical absorption ratio is affected by the gasoline-methanol mixing ratio, its temperature and the quantity of fuel additives. 3.Concerning the distillation temperature, the initial point of all sorts of fuels is almost same,but 10% point and 35-60% point of mixed fuels are lower than those of gasoline only. 4.In case of throttle valve opening set, engine output using the mixed fuels is decreased compared to gasoline, but thermal efficiency is increased as a consequence of decreasing specific energy consumption. 5.In case of fixed load test, thermal efficiency is increased at low engine speed even under low part-load as well as under comparatively high part-load including full load. 6.CO and NOx emissions are reduced remarkably with the mixed fuels.

  • This paper attempts to provide a way to improvement in trade & commerce between Korea and Russia, analyzing the influence of the circumstances of the Russian economy on economic relations between the two countries. The study briefly reviews the current situation of the Russian economy, and tries to examine the strong points to be considered as leverage for cooperation and the weak points to be overcome. Previous studies have determined that the Russian economy has unlimited potential for growth, because it is endowed with abundant resources, and has a government willing to reform for the opening of the economy, as well as high-quality labor. However, the economic structure is vulnerable to impact of the worldwide financial crisis. It is not possible to overlook its institutional fragility and vulnerability such as a corrupt bureaucracy or a relatively large black market. These undesirable factors may not only undermine the basis of Russia economy but also a hindrance to economic cooperation by increasing economic uncertainty. This paper attempts to analyze comprehensively the socio-economic factors that influence the open-economy of Russia, and to illustrate strategies for improvement in trade and commerce through the viewpoint of Korean firms that are already in business or are trying to enter in the near future. Some measures to improve their economic cooperation are suggested at the end.

  • The purpose of this study is to analyze the process of lots-subdivision within the block of Gaeksa at Dongnae-bu under the rule of Japanese Imperialism. Gaeksa of the old government office was the sanctuary that symbolized the sovereignty. Therefore it was naturally a main object of demolition and then the site was converted to other purpose. And Gaeksa was not only converted into the elementary school and the public market but the historic site also processed to break down for opening the road through Japanese Occupation of Korea. The main reasons of lots-subdivision were the transfer from state property to private ownership and the urban development project. Needless to say, the particular major reason was derived from the intention of Japanese Imperialism to destroy the traditional urban. As a result, Gaeksa can not be recognized the traces of today and contributes to the demolition of the remaining ancient building. Finally the deformed urban structure was left over from destroyed building.

  • Agro-fishing villages of agriculture and fishery are suffering deepening gap with urban areas due to depreciation from their products market opening pressure. They are facing problems of decreasing and aging population, poor settlement environment, etc. and losing their vitality for their low productivity and lack of young labor force. These issues of agro-fishing villages of agriculture and fishery are divided in so various items and classes that it is plausible to approach in a way to connect each issue in a small frame of each by selecting sub topics according to each item and each class rather than to solve the issues in a large frame. Chungchungnam-do is approaching the issues through 3 agro innovations(agro fishery, agro fishing villages, agro fishing people) in local government level and Durae enterprises are solving local problems through the self supporting residents' community business by utilizing local resources. This study is to draw clues and solutions to vitalize agro fishery villages through community businesses by detailed reviews and research on cases of Durae enterprises' characteristics and their vitalizations and provide a new alternative plan to agro fishery villages losing their vitality and demolishing their communities.

  • The paper chooses four trade competitiveness assessment indices to compare the international competitiveness of Computer and Information Service(C&IS) trade between South Korea, China and Japan. The results show that the competitiveness of China is the strongest, Japan secondary and Korea the weakest among the three countries. However, the competitiveness of Korea can be promoted the most quickly and it has exceeded Japan according to TC and NXRCA indices. Meanwhile, there was still a huge gap between the three countries and the two world strong countries-India and Ireland. The main findings of empirical research on influencing factors show that domestic market demand and trade opening degree are the two most important factors influencing the competitiveness of three-country C&IS trade. At the same time, improving the utilization of C&IS and realizing good interaction of C&IS trade and electronic information, communication and other relevant and auxiliary industries can also contribute to the competitiveness improvement.

  • With the opening in construction market, more diversified and internationalized construction culture is imported, but the level of our construction culture and policy is still not met the international standards. For example, there is a difference in the liquidated damages at delay due to the reason of builder imputation during the public construction project comparing the international standards like damages. It may lead to the potential claim. In this study, via comparing and analysis on the relevant international standards and extension expense for terms of work, actual compensation is selected, and improvement of liquidated damages like damages is presented.

  • Purpose - This study was conducted under the assumption that brand A, a store of company Z of Pangyo, with a new store at Pangyo station is targeting the Bundang-gu area of the newly developed city of Seongnam. Research design, data, methodology - As a result of demand forecasting using geometric series models, an extrapolation of past trends provided the coefficient estimates, without utilizing regression analysis on a constant increase in children's wear, for which the population size and estimated parameter were required. Results - Demand forecasting on the basis of past trends indicates the likelihood that sales of discount stores in the Bundang area, where brand A currently has a presence, would fetch a higher estimated value than that of the average discount store in the country during 2015. If past trends persist, future sales of operational stores are likely to increase. Conclusions - In evaluating location using the simple weighting model, Seohyun Lotte Mart obtained a high rating amongst new stores in Pangyo, on the basis of accessibility, demand class, and existing stores. Therefore, when opening a new counter at a relevant store, a positive effect can be predicted.
