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.

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.

고전력수용가포털(Consumer Portal)은 소비자의 다양한 장치들과 광역 네트워크, 그리고 에너지서비스사업자(ESP: 한전 등)의 서비스 애플리케이션 플랫폼을 연결하는 물리적 링크이자 논리적 결합으로, 전력서비스 체계에서 소비자-공급자 간 정보교환과 서비스 거래를 담당하는 양방향 통신의 핵심 인프라로서 포털이다. 전력수용가포털(Consumer Portal)의 성공적인 설계와 개발을 위해서는 효율성, 경제성, 확장성을 고려한 네트워크 설계가 선행되어야 한다. 그러나 전력수용가 포털의 네트워크 설계에 필요한 네트워크 용량 설계 모델링에 대한 공학적 연구는 아직 부족한 실정이다. 본 논문에서는 전력수용가포털의 네트워크 설계에 필요한 네트워크 용량 설계 모델링 방법을 논하고 실제 구축 중인 시스템에 적용하였다. 그 결과 기존 네트워크 설계방법의 문제점을 파악하고, 개선하여 네트워크의 최대수용 단말기의 수를 $30{\sim}40$배 증대시킬 수 있는 데이터 수집 알고리즘을 개발할 수 있게 되었다.

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.
