In Japan, a lot of elderly housing types have been developed in order to meet various needs of the older person and the change of social situations. Elderly housings can be divided into three categories elderly housings for healthy older persons, elderly care homes for the healthy and elderly care facilities for the unhealthy. Elderly housings include public and private rental housings. Sometimes they can be designated only for the elderly. Elderly care homes for the healthy elderly include full fee charging elderly housing, elderly homes, low fee charging elderly homes and care houses. Elderly care facilities for the unhealthy elderly consist of full fee charging elderly care homes, group homes for the dementia, elderly health facilities, nursing homes, elderly hospitals, and so on. However "elderly care facilities" have been proved not to be efficient for the delivery of elderly welfare services nor satisfactory to the frail older person. Therefore, based on the concept of the "Normalization", daily services have been provided for the elderly in order that they can live at their own home in the community for themselves. As a result, Japan aims not only to reduce elderly welfare expenses but also to increase elderly users' satisfaction. Emphasis on non-institutionalization and in-home services, regional characterization, harmony between Hard and Soft, user oriented services, substantiality, universal design and so on are sought for the sake of those goals.

The modern transportation and mobility sector is expected to encounter high penetration of Electric Vehicles (EVs) because EVs contribute to reducing the harmful emissions from fossil fuel-powered vehicles. With the prospective growth of EVs, sufficient and convenient facilities for fast charging are crucial toward satisfying the EVs' quick charging demand during their trip. Therefore, the Fast Electric Vehicle Charging Stations (FECS) will be a similar role to gas stations. In this paper, we study a charging scheduling problem for the FECS with solar photovoltaic (PV) and an Energy Storage System (ESS). We formulate an optimization problem that minimizes the operational costs of FECS. There are two cost and one revenue terms that are buying cost from main grid power, ESS degradation cost, and revenue from the charging fee of the EVs. Simulation results show that the proposed scheduling algorithm reduces the daily operational cost by effectively using solar PV and ESS.

Background : As parking problem caused by increasing owner-driver and patients concentrating to a general hospital is becoming one of the dissatisfactions in medical care. It is time that a general hospital should solve the parking problem in a desirable way. The purpose of this survey is to let the clients understand the basic motivation of the pay parking and develop the better parking system. Methods : Clients of a tertiary care hospital in Chon-ju were surveyed by means of a questionnaire. All in all, 193 subjects answered the questionnaire. Results : In relation to previous experiences, 39.6% of the subjects experienced inconvenience with confused parking lot and the shortage of parking space. Under the current parking system, the subjects who felt the available parking space was enough were more than those who didn't 62.7% of the subjects answered that they could find the parking lot easily. 33.2% of the subjects mentioned that it was not easy to drive in the parking area ; The reasons were pointed out the shortage of space, disordered parking, and insufficient guide. 12.8% of the subjects satisfied with the current administering system of parking lot. The outpatients were more affirmative than the admitted patients about the charging system. As for the parking fee, 64% of the subjects answered that it is expensive, and 89.5% of the subjects thought imposing of parking fee is irrational. Conclusion : To say as a whole, the basic purpose of the charging system are more or less accepted. However, the management details like parking facilities and payment method are dissatisfactory, so it is necessary to improve the management system. It is also noted that the inpatients showed more negative attitude than the outpatients with the charging system. To secure a more convenient parking, the parking system should be considered in relation to the information service, kind guidance, improve facilities, personnel cooperation, fix outpatient scheduling system, etc.

As Internet usage widely grows, online content services such as newspaper, magazine, music, game and movie are provided with a fee-based subscription. Many content services providers consider charging a usage fee into its service provisions as one of the Internet business models for increasing revenue. There are customer resistances to adopting the fee-based service provision on the Web. Previous research in information systems (IS)has focused on the analysis of adoption of information technology or systems in the individual ororganization level. No principle research has been carried out on the user adoption behavior of online content services provisions. As users actively access content services on the Web, it needs to explore user adoption behavior in different settings. Many IS researcher have employedquantitative approaches, even though they deal with the process of user behavior regarding the information technology or system. In this study, we attempt to discover how customers adopt the fee-based provision of online content services by employing grounded theory, one of the principal qualitative research methods.

Arguments against charging fees for use of recreational forests and parks generally rest on the assumption that the public sector has the responsibility to provide as many recreational opportunities as it can to all visitors in Korea. The entrance fee in recreational forests allowed some governmental resource management agencies to keep a portion of user fees generated on-site, instead of returning all revenue to the general treasury. Funded primarily through entrance, activity, parking, and mountain villa-use fees, this legislation has been successful in reducing the maintenance backlog for participating agencies. However, it is unclear what effect user fees might have on visitors attending interpretive programs and the benefits that agencies might receive from implementing this policy. From this point of view, this study is a similar case at the Visitor Center and Species Restoration Center at Jirisan in terms of fee-based field trips to the places. In this research, two hundred twenty-three visitors at the Visitor Center and Species Restoration Center at Jirisan National Park answered questions about their trips from 2005 to 2006. Results indicted that the ecoguide not only increased visitor's appreciation of the resource, but also enhanced their perceptions of the Korean National Park Service (KNPS) fee policies.

Background : Because of introduction of nationwide health care system in 1989 and the improvement of socioeconomic status of population the number of outpatient visiting university hospital has good facilities and manpower has increased. So the waiting time for medical service at university hospital are lengthened. Particularly outpatients complain that waiting for prescribed drugs at pharmacy depart are long. Reducing waiting time at pharmacy depart door-to-door delivery system that the patients applying for door-to-door delivery receive prescribed drug at home without waiting at pharmacy depart were studied. The objective of this study is to analysis the opinion of outpatients for door-to-door delivery system, to study the appropriateness of adopting the system and to produce ideal model for the system. Method : Outpatients waiting drug at pharmacy depart were questioned about door-to-door delivery system. to find the factors affect utilizing the system the logistic regression was used. Result : 83.3% of the patients want to utilize the system without charging, and 72.9% of the patients want to utilized system with charging. 68.3% of patients with charging want to use this system because of long waiting time at pharmacy depart. 50% of patients who do not want to use door-to-door do not use this system because of incorrect delivery. The affecting factors to utilize the system were sex, waiting time, fee. Conclusion : The model for door to door delivery system. 1. door-to-door personnel reside in hospital and the patient want to utilize the system apply for the delivery with charging. 2. The applied drugs dispense at spare time. 3. Delivery company gathers drug at appointed time and delivers. 4. The delivery fee is 2,000-3,000 won. 5. To prevent from loss and changing the drug the name of patient on packet are printed and drug packet are sealed. 6. The company submit the confirm sheet which are written that the patient received drug correctly to hospital. 7. The delivery time of drug is reserved for the convenience of receiving.

User fees have been employed by libraries as far back as the mid-1800s in both United States and England. By the late 1800s and early : 1900s, the charging of user fees for some library products and services had become a reality in many public and academic libraries. Yet the practice has created controversy when computer-aided reference service began to charge especially in the publicly funded libraries. There are two extream arguments on library reference service fees : one is for and the other is against. most fee o n.0, pponents base their stand on morality. They argue that charging fees for any service is wrong because it violates the user's right of access to information and regard it as an act of decrease human life chances as well as an act of censor. But those who favour fees argue that it is necessary to separate the rhetoric from the reality and to distinguish what libraries are from what they do. The study revealed that library has two options. One is strict free of charge and the other is charging for selected library services. Whatever options the library may take, library had to decide an overall reference service policy. The level and scope of service, audience, necessary fund (who and how) and many other physical and metaphysical things must be considered. However, the first option will necessary be to limit services while there is no loss of traditional philosophical service element. Yet, if to provide a wide range of choices and to create conditions more hospitable to competition from the private information sector and for better evolutional selection, the second option(fee-based service) gives more benefit to the users while there is a loss of fundamental service philosophy.

The purpose of this research is to valuate the economic value of the arboretum which will be provided in Multifunctional Administrative City by estimating citizens' willingness to pay with double-bounded dichotomous choice contingent valuation method, and to provide the basic information necessary for designing and managing it for the future by identifying the types of the variables affecting the WTP. It was found that respondent's average WTP for arboretum was \23,508, and when this figures applied to all the Seoul citizens aged between 20 and 59, the economic value of it was \157,000,000,000. The variables affecting the amount of WTP were visit intention, variety seeking tendency, level of income and environmental attitude. However, environmental attitude negatively affected the amount of WTP. Average WTP for the entrance fee was \5,090, and both variety seeking tendency and visit intention were influencing factor affecting the amount of WTP. Respondents were taking charging entrance fee for granted because most of arboretums are commercial. It can be expected that much of maintenance cost will be covered from the entrance fee.
