We consider a two-fare, two-period airline seat capacity allocation problem where consumers may choose different options in purchasing an airline ticket. A consumer may decide to wait for reopening of the same fare class ticket which is originally intended to buy, or may buy a different fare class ticket within the same period, if the originally requested fare is unavailable. We investigate the impact of the consumer buying behavior on the optimal solutions and the expected revenue.

Objectives: The purpose of this study was to investigate the differences of capacity of local health organization to regional characteristics and the influence of organizational capacity on organizational performance. Methods: The study used the secondary data for 160 local public health organizations from $5^{th}$ Community Health Plans and 2009 Community Health Survey. The collected data were analyzed using one-way ANOVA and multiple regression analysis. Results: Work force and budget showed differences in regional size and elderly population rate. And consumer satisfaction and health care utilization showed differenced in work force and budget. The regression model with total number of employee, number of registered nurses, number of doctors and budget against consumer satisfaction was statistically significant (F=14.70, p=<.001), and number of registered nurses was identified as a factor influencing consumer satisfaction. This model also explained 20.5% of service satisfaction. The regression model for consumer satisfaction was statistically significant (F=45.98, p=<.001), and total number of employee nurses was identified as a factor influencing health care utilization. This model also explained 53.1% of utilization. Conclusions: The findings of this study imply that organizational capacity as work force and budget should be increased to improve the organizational performance as consumer satisfaction and health care utilization.

This study was carried out to understand the consumer complaining behavior of rural women leaders and to identify variables affecting complaining behavior. 403 samples were collected from the rural women leaders in rural areas by mailed questionnaire from June 1 to June 20 in 1996. The data was analyzed by frequency, percentage, mean, chi-square, F-test, correlation, regression using SPSS/PC＋ program. Most of rural women leaders experienced consumer dissatisfaction and damage, but they mainly took private complaining behavior. The rate of the non-complaining behavior was 20.1%. They recognized that consumer dissatisfaction and damage was due to external attribution. The results showed that the most influential variables for the consumer complaining behavior of rural women leaders were age and consumer capacity. The older they were and the more consumer capacity they had. the more active complaining behavior was taken.

Consumer Portal is defined as "a combination of hardware and software that enables two-way communication between energy service provider(ESP, like KEPCO) and equipment within the consumer's premises". The portal provides both a physical link(between wires, radio waves, and other media) and a logical link(translating among language-like codes and etiquette-like protocols) between in-building and wide-area access networks. Thus, the consumer portal is an important, open public shared infrastructure in the future vision of energy services. In this paper, we describe a new methodology for local communication and computer network capacity design of consumer portal, and also presents capacity calculation method using a network system limitation factors. By the approach, we can check into the limitations of existing methods, and propose an improved data processing algorithm that can expand the maximum number of the networked end-use devices up to $30{\sim}40$ times. For validation, we applies the proposed methode to our real system design. Our contribution will help electrical power information network design.

According to consumer's washing behavior, the washing efficiency of three different types of washing machines-pulsator, agitator, and drum was studied. Their detergency, rinsing efficiency, and the degree of fabric damage, tangle, and wrinkle were evaluated. The results showed that efficient washing capacity was different from the specified capacity of washing machine. Detergency and rinsing efficiency frere apparently decreased when more than 50% of capacity was loaded in washing machine of pulsator type, and 80% for agitator or drum types. They were also affected by detergent adding methods, and decreased in the order of water-detergent-washing load> washing load-detergent-water> washing load-water-detergent. Rinsing efficiency was significantly improved when the rinsing temperature was set above washing temperature. In addition, it was revealed that detergency, fabric damage, wrinkle, and tangle were highly correlated. The relationships between detergency and tangle were different for different types of washing machine. Positive relationships were found for agitator and drum types, whereas negative for pulsator type.

This study analyzes the comsumer complaints that are listed on bulletin board (or Q & A page) of mobile game sites in order to search for comsumer problems in the contents of mobile games. This analysis includes 3,664 cases of complaints on 17 mobile game sites. The finding indicates that they can be categorized into 10 types of complaints: game errors, how to play, game quality, game capacity, fee inquiry, excessive fees, lack of information, refund, unfulfilment of promises, game support. The problems with the game itself account for 54.8% of total complaints, and unsatisfaction from game fees and others take up 25.5% and 19.7% respectively. Therefore, we suggest that first, the quality of mobile games and consumer education be improved, second, information about game fees be provided to consumers more sufficiently in a proper manner, and lastly pertinent regulations on consumer damages compensation and adhesion contracts be established.
