This study measures patients' meal satisfaction according to the type of operation (self-operation and contract operation) and identifies improvement areas. A survey was conducted using 183 contract operation patients and 60 self-operation patients receiving general meals. The mean score for satisfaction for the whole sample was 3.42 (self-operation = 3.51; contract operation = 3.39), and self-operation satisfaction was significantly higher than contract operation satisfaction. Mean scores were 2.98 for food, 3.26 for menu composition, 3.57 for sanitation, 3.78 for distribution meal services, and 3.50 for menu information. Self-operation showed a higher satisfaction level than the contract operation in food and menu composition. The ccontract operation showed a higher level of satisfaction than self-operation in sanitation, distribution meal services, and menu information. In terms of feeling dissatisfaction with meal services, both groups showed the highest dissatisfaction with food and menus, and both groups agreed on food and menus that required the greatest improvement. Based on the results, contract operation managers should develop and apply menus considering their preferences. Dietitians of self-operation strengthen communication between meal service staff and patients by carrying out periodic and systematic service education on self-operation.

We describe the Ubiquitous Healthcare Service(UHS) architecture, a new service-provision architecture, covering the basic concept, component and their roles and the service-provision mechanism. A UHS provides services in two phases, a service composition phase in which Healthcare Service Elements (HSEs) are combined on the basis of Healthcare Service Agents (HSAs), and a Healthcare Service emergence phase in which a new HSA is obtained on the basis of the history usage of HSEs and HSAs. A UHS can handle various types of HSEs, representing web services, resources about healthcare domain. The establishment of UHS technologies on networks will provide various services within ubiquitous-computing environments.

In this paper, we proposed the next generation mobile convergence service business model creation methodology. In order to establish such a business model creation methodology framework, we first introduce the service model based on our previous research results on next generation mobile convergence services. The service model contains several components such as infrastructures, operations, and provision of services that are indispensible for providing the next generation mobile services. Finally, by adding service and value flows to the developed service model, we propose the next generation mobile services business model creation methodology. To achieve this objective, we first derive necessary components of business model including actors, their relationships, and roles. In addition, we propose service composition methodology for creating new mobile services and its corresponding business models.

Open Decision Support System(DSS) is an automated and transparent system that is built to be shared both within and across organizations. The open DSS has been thought to be a set of decision components that are communicating through Web protocols. These characteristics intuitively invite the Web services concepts, which are currently one of the new trends in network-based business services. However, web services still are not active enough to be autonomous, and to provide for composing functionalities. These lead to the motivation on building a sophisticated web service to contain these features and to utilize web services on behalf of the user. This paper aims to propose a new concept of Meta Web Service, a web service-based open DSS. Decision modules in a dynamic and open DSS can be viewed as a web service. The Meta Web Service understands the users problem statement with ontology, performs web service discovery, web service composition, and automatically generates codes for composite web service execution. A prototype of example web service has been developed to show the feasibility of the proposed idea.

Integration systems help users consume services more effectively. However, previous integration systems can only enable predefined service cooperation to satisfy users, which is difficult to achieve user-centric service composition in dynamic environments. Therefore, in this paper, a dynamic service integration system is proposed to automatically combine services based on usage history. With this system, services can be dynamically composed to meet users' needs and information can be flexibly transited among heterogeneous services.

The Web Services descriptions such as DAML-S/OWL-S, BPEL4WS and WSMF focusing on the functional aspects of Web Services have limitations for the representation of the conceptual and semantic capabilities of Web Services, although WSMF is based on ontology and can represent the goal of Web Services. This paper proposes the new description formalism based on the competence ontology that can represent both functional and semantic aspects of Web Services. This paper also presents the integration and the composition of Web Services by means of Data Mediator(D-Mediator) and Control Mediator(C-Mediator) to mediate compositional in compatibility between heterogeneous Web Services.

The Cassava(Manihot esculenta Crantz) is a tropical root crop, originally from Amazonia, that provides the staple food of an estimated 800 million people worldwide. It belongs to the family Euphorbiaceae which also includes rubber (Hevea brasiliensis) and castor bean (Ricinus communis). Among tropical crops, rice, sugarcane, maize and cassava are the most important sources of calories for human consumption. Problems in the propagation of cassava are virus diseases and low rates of seed germination. So we tried to optimize protocols for mass production of somatic embryo amenable to large-scale vegetative propagation of Cassava. After in vitro eight-week culture of leaves of Cassava, the medium which contained the 2,4-D, BAP and IBA showed the highest callus induction rate, embryogenesis callus formation rate and somatic embryo formation in Cassava culture. In the medium with GA₃ and myo-inositol, shoots were most vigorously regenerated from somatic embryos of Cassava. Our experiments confirmed that in vitro growth and multiplication of plantlets could depend on its reaction to the different medium composition, and this micropropagation techniques could be a useful system for healthy and vigorous plant production.

In order to overcome such limits of hotel sales, the role of hotel public section, such as eating and drinking facilities, is very important. Moreover, city hotels increase the value of public section by providing various event for citizens as well as and services for banquet. Since Jeju has urban hotels and resort hotels mixed together, their Plane types and area composition based on the characters of customers using the public section are different from ones of other cities. The purpose of this study is to provide basic material for the qualify improvement of the luxury resort hotels in Jeju. We examine the tendency of the systematic Plane composition of the Public sections which take different types of customers, such as Jeju people and tourists, into consideration, analyzing the plane types and the area composition of the luxury resort hotels in Jeju. The study shows that the public part of hotels always had great impact on hotels sales depending on the compositions of plane and area.

As one of the challenges providing sufficient Social Overhead Capital (SOC), such as cultural and sports facilities, installing small libraries and remodeling old public libraries are crucial to provide local community a public space and specialized services. In order to achieve such objectives, those libraries need to designate special themes while operating and providing services. In this study, we sought to find the relationship between the specialized themes and the spatial composition of the library. For this purpose, we investigated the specialized themes, spaces, services, spatial composition of program, and external environment. Analysis results showed that those libraries need to coordinate various areas according to the respective themes as well as categorization for its specialization subjects in order to stimulate activities of the libraries and to increase the usage rates. In addition, we have identified that a variety of spaces, such as thematic experience zones, are needed to improve the libraries' performance.
