Purpose: The purpose of this study was to evaluate the correct use of inhalers and to examine the patients characteristics affecting correct use of inhalers in patients with obstructive pulmonary disease. Method: Subjects were 280 patients with obstructive pulmonary disease who visited the internal pulmonary outpatient departments in 2 university hospitals in Korea. Inhaler use of each patient was assessed using a checklist recommended by the National Asthma Education and Prevention Program Expert Panel. Result: Most subjects used a DPI or MDI. The overall mean score of correct use was 72.09. Most subjects responded they knew well how to use their inhalers. Most frequent error was 'not fully exhaling before inhalation'. A younger age, higher educational level, living with family, and awareness of inhaler use were significantly associated with correct use of inhalers. Conclusion: The findings of this study showed that most of patients were unable to use inhalers correctly even though they had prior educational experiences. Regular assessing of inhaler use and adequate inhaler education considering patients characteristics by nurses are needed.

This research investigates the factors influencing price sensitivity in fashion products. This study incorporates three essential variables, which were likely to influence price sensitivity: the subjective shopping value of consumers, objective purpose of use, and social situation according to the shopping companions of consumers. A sample of young adult consumers (who had purchase experience of fashion products during the last six-months) was surveyed using a self-administered questionnaire. A 3-way ANOVA was used to evaluate the data. The results show that the utilitarian shopping value of consumers was more sensitive in price than the hedonic shopping value and a self-using purchase was more sensitive in price than a gift-giving purchase. In addition, a correlation effect was significant between the purpose of use and social situation. In addition, the correlation effect among all of the three variables was also significant.

In the urban area where rapid suburbanization trend continues, the role of mixed use building is controversial. It is argued that the mixed use building is an effective tool to recover residential function of urban core(urban regeneration). It is also argued that the building is a cause of serious urban problems, such as congestion, public service shortages. The fundamental purpose of this study is to examine the role of mixed use building in terms of urban growth management in Seoul. For this purpose, data of mixed use building from 1981 to 2007 are collected and analysed. The results show that most of mixed use buildings are located in either sub-centers or population losing areas, rather than traditional urban core. Therefore, it is hard to accept that the two controversial arguments. The mixed use building noncore areas in most cases. However, it dose help to increase population inflow in non-core areas. it is difficult to accept the public service assertion which states that super-high rise mixed use building causes public service congestion, because the building is built in population losing or demand decreasing area. Based on these findings this study suggests some policy alternatives such as urban service boundary or concurrency program to management urban growth.

The purpose of this paper is to examine some difficulties in water management of agricultural reservoirs in Korea, for there are approximately more than 15,000 reservoirs which are now being utilized for the purpose of irrigation, along with the much amount of expenses and labors to be invested against droughts and floods periodically occurred. Recently, the effective use of water resources in the agricultural reservoirs with a single purpose, is becomming multiple according to the alterable environment of water use. Therefore, the task to allocate agricultural water rationally and economically must be solved for the multiple use of agricultural reservoirs. On the basis of the above statement, this study aims at suggesting the rational method of water management by introducing an optimal technique to allocate the water in an existing agricultural reservoir rationally, for the sake of maximizing the economic effect. To achieve this objective, a reservoir, called "0-Bongje" as a sample of the case study, is selected for an agricultural water development proiect of medium scale. As a model for the optimum allocation of water in the multi-purpose use of reservoirs a linear programming model is developed and analyzed. As a result, findings of the study are as follows : First, a linear programing model is developed for the optimum allocation of water in the multi-purpose use of agricultural reservoirs. By adopting the model in the case of reservoir called "O-Bongje," the optimum solution for such various objects as irrigation area, the amount of domestic water supply, the size of power generation, and the size of reservoir storage, etc., can be obtained. Second, by comparing the net benefits in each object under the changing condition of inflow into the reservoir, the factors which can most affect the yearly total net benefit can be drawn, and they are in the order of the amount of domestic water supply, irrigation area, and power generation. Third, the sensitivity analysis for the decision variable of irrigation which may have a first priority among the objects indicate that the effective method of water management can be rapidly suggested in accordance with a condition under the decreasing area of irrigation. Fourth, in the case of decision making on the water allocation policy in an existing multi-purpose reservoir, the rapid comparison of numerous alternatives can be possible by adopting the linear programming model. Besides, as the resources can be analyed in connection with various activities, it can be concluded that the linear programing model developed in this study is more quantitative than the traditional methods of analysis. Fifth, all the possible constraint equations, in using a linear programming model for adopting a water allocation problem in the agricultural reservoirs, are presented, and the method of analysis is also suggested in this study. Finally, as the linear programming model in this study is found comprehensive, the model can be adopted in any different kind of conditions of agricultural reservoirs for the purpose of analyzing optimum water allocation, if the economic and technical coefficients are known, and the decision variable is changed in accordance with the changing condition of irrigation area.
