The aim of the study is to implement a factor analysis of the determinants of pricing in a state-regulated competitive market using economic and mathematical modelling methods and to develop ways to improve the pricing environment of the market under study. The purpose of the work defines the main objectives: (i) to investigate the features of the competitive model of the Ukrainian flour market; (ii) to analyse the current price conjuncture of the flour market and the dynamics of the main determinants of pricing; (iii)to develop ways of improving the price situation on the flour market on the basis of the factor analysis on the results of economic and mathematical modelling. In order to ensure the reliability and validity of the research results, the following methods were applied: the logical-dialectical method of scientific knowledge in the study of the main theoretical aspects of flour market functioning, the method of logical generalisation and synthesis, comparison, factor analysis, correlation and regression analysis, the graphical method, etc. It has been shown that pricing in a state-regulated competitive market has its own characteristics. For example, in the flour market the price of goods cannot be influenced by producers (sellers) by any methods, therefore determinants of pricing by indirect influence have been taken into account. The five-factor power model of wheat flour price has been constructed. It was substantiated that the price of wheat flour in Ukraine is mostly influenced by consumer price index (0.92 %). The received complex model of wheat flour price may be used also for medium-term forecasting and working out the ways of price formation optimization in the flour market.

Changes in consumer purchasing patterns due to construction of large Western-style commercial buildings and introduction of new purchasing methods in South Korea in the 1990s led to a gradual decline in traditional markets. Under such a new environment, Yukgeori market, one of Korea's exemplary markets, has continued to develop and survive, while maintaining the traditional market form of Korea, both physically and operationally. Therefore, to find the characteristics of spatial configurations supporting the revitalization of traditional market, we deduced social attributes of spaces in street network of Cheongju city and the neighborhood including Yukgeori market by calculating the depths of nodes in the network using analysis models based on space syntax. The results illustrated that long street with the function to attract people and acts as a bridge of traffic and communication between highly modernized commercial area and traditional market can lead to continuous win-win development of both areas and the revitalization of traditional market through the promotion of social activities in the market. We expect that sound and sustainable development of contemporary cities, which lost tradition, will be achieved through the results of this study.

The trend towards forming economic blocs coupled with global economic arrangements such as DDA and FTA increase pressure on the liberalization of the agricultural sector. South Korea is taking part in the DDA negotiations. Once the DDA negotiations are implemented, the extent of liberation of the agricultural market is expected to be wider and timing of market opening is sooner than those effects of the UR agricultural agreement. A reduction in tariff rates and the government subsidy will follow, accordingly. However, many analysts in the agricultural sector express deep concern over a negative development in local agricultural market as demonstrated in China where the local market was dominated by imported agricultural products. This study aimed to investigate progress that China made in favor of the agricultural industry, including environment-friendly agricultural policy, and suggest ideas to drive the development of the agricultural industry in a better direction in Korea by comparing the two countries.

This study was to examine the degree of market orientated effort by hospital type and size,. and analyzed the moderating effect of environments between market orientation and it's performance. First, there was no significant differences by hospital type, such public hospital, university hospital, and private hospital. However, the orders of market orientation implementation was university hospital. private hospital, and public hospital This finding suggest that university hospital and public hospital, should be market-oriented, or customer-oriented more now, relatively. Second, there were no significant differences in marketing as management policy by hospital types, i.e. public, university or private sector hospitals. However, as to the intensity of the implementation of the market-oriented approach, private hospitals came first, followed by the university hospitals, then the public ones. This finding suggests that university and public hospitals should be more market or customer oriented to compete in the market. Third, only the competitive environment does active moderating roll on hospital performance. The competitive environmental factor forces the organization to be more market oriented. This means the more you are positively situated in the competitive environment, the more you are looking for a market oriented approach. You become more aware of the value of customers and you become more focused on the customer satisfaction and thus become more patient oriented in every facet of decision making. And market oriented hospitals recognize the importance of utilization of high tech medical treatment skills and equipment in patient care. Fourth, according the analysis, market oriented effort gives more influence on hospital performance than the environmental factors. This means that the market oriented effort should become a culture of the hospital which seeks to out distance themselves from its competitors.

Recently, T-Commerce is emerging to provide new services, with the proliferation of digital broadcasting services. However, T-Commerce market and TV home shopping market are being classified as a legal policy on other markets, such as regulated in the service of live broadcasts. The factor that has inhibited activation T-Commerce related to the lack of appropriate institutions and legal systems in the market, despite the environment with the digital broadcasting service is being spread. We were performed conjoint analysis. For this analysis, we select attributes as a quality attractive factors that significantly affects the satisfaction of TV based shopping customers through previous studies. The results showed that the TV-based shopping customers are important to think 'Responsive', 'Playfulness', 'Live broadcast', 'Convenience' and 'Bidirectional' in the order. The 'Responsive' and 'Live broadcast' of such attributes are served as possible only in TV home shopping, because these attributes don't service due to legal and institutional regulations in T-commerce market. The cluster analysis result also showed that TV shopping consumers are more important to think 'Responsive', 'Playfulness', 'Live broadcast' than 'Convenience' and 'Bidirectional', except one of the classification clusters. If real-time broadcast service is impossible because of the legal and institutional regulations, it seems to require the expansion of the services linked the terrestrial broadcasting to the activating T-Commerce market.

Deregulations and market practices in power industry have brought great challenges to the system planning area. In particular, they introduce a variety of uncertainties to system planning. New techniques are required to cope with such uncertainties. As a promising approach, probabilistic methods are attracting more and more attentions by system planners. In small signal stability analysis, generation control parameters play an important role in determining the stability margin. The objective of this paper is to investigate power system state matrix sensitivity characteristics with respect to system parameter uncertainties with analytical and numerical approaches and to identify those parameters have great impact on system eigenvalues, therefore, the system stability properties. Those identified parameter variations need to be investigated with priority. The results can be used to help Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs) perform planning studies under the open access environment.
