This study of elderly households living conditions to determine the overall status in the housing environment is to understand. To this end, the stage of elderly as a framework to target living consciousness, living space composition, housing Environment composition of elderly households with a comprehensive understanding and analyzes were employed. For this research is a survey conducted on senior citizens(over 60) in Busan, Korea. The major findings are as followings; In the living consciousness, the elderly households showed high perception of dependency but the age of the elderly increases, depends on the parent to the child. Also depending on the aging of the elderly considered health more important than economic conditions. The requirements for living space composition, most respondents prefer to stay in the same place where they currently reside. Move into the new housing was also identified. It was recognized that elderly households not only required living in co-residential space with their families, but also the necessity for individual space. The home environments composition, health care and social welfare support services appears overall the elderly of stage. The age of the elderly increases, a strong demand for care and support service were identified. Health activities in leisure and social activities and social activities, as age increased mainly done by the convenience of public transportation has been identified that are important.

As web service technologies are widely used, there have been many efforts to develop approaches for recommending appropriate web services to users in complex and dynamic service environments. In addition, for the effective development of service mashups, service recommender systems that are specialized for service composition have been developed. However, existing service recommender systems for service mashups are not effective at recommending services in a personalized manner that reflect developers' preferences. To deal with this issue, we propose an approach that recommends services based on the similarities between mashup developers who have developed similar service mashups. The proposed approach is then evaluated by using the mashup data retrieved from ProgrammableWeb. The evaluation results clearly show that the proposed approach is an effective way of improving service recommendations compared to the traditional user-based collaborative filtering algorithm.

Purpose: The purpose of this study is to reduce loneliness through a systematic review by analyzing the effectiveness, composition and method of non-face-to-face services on the elderly living in the local community. Methods: From June 11 to 15, 2021, related papers were searched using six databases: Ovid-Medline, Ovid-Embase, Cochrane library, KISS, Koreamed, and RISS. Two authors independently assessed the quality of selected studies and data was synthesized. Results: Non-face-to-face services promoted loneliness and social isolation, social support and quality of life, other emotional responses, attitudes and usability, and diet and exercise. As the composition and method of services are being tried in various ways, it is necessary to develop a comprehensive service using ICT to provide systematic intervention to the elderly in the local community. Conclusion: Reflecting the difficulties in implementing face-to-face services due to COVID-19, it is expected to be used as basic data for developing comprehensive non-face-to-face services that meet the major needs of the elderly people and maintain the continuity of care.

The advance in Service-Oriented Architecture (SOA) and web services has led to the development of new types of a system in which heterogeneous service components can connect and compose to solve a complex business problem. In the SOA, even though these service components are valid in their functionality, there is a need to test their behaviors when those services are composited. In recent years, WS-BPEL has received a wide acceptance as a means of integrating distributed service components. To test the composite service, the existing testing techniques have been focused on the functional features based on the WS-BPEL process. However as SOA approach is applying to real-time software development, the performance of composite service becomes one of important issues. This paper proposes a technique to the performance testing of a composite service with WS-BPEL extension which combined with the concept of aspect. Our WS-BPEL extension has been made towards annotating aspect component which is measuring the response time of the composite service. This paper also explains the procedure of performance testing with on-line transaction system. Our technique can apply to choose an adequate component in service composition with considering the performance among several candidate web service components.

Recently the web service area is rapidly growing as the next generation IT paradigm because of increase of concern about SOA(Services-Oriented Architecture) and growth of B2B market. Since a service discovery through UDDI(Universal Description, Discovery and Integration) is limited to a functional requirement, it is not considered an effect on frequency of service using and reliability of mutual relation. That is, a quality as nonfunctional aspect of web service is regarded as important factor for a success between consumer and provider. Therefore, the web service selection method with considering the quality is necessary. This paper suggests the agent-based quality broker architecture and selection process which helps to find a service providing the optimum quality that the consumer needs in a position of service consumer. A theory of agent is accepted widely and suitable for proposed system architecture in the circumstance of distributed and heterogeneous environment like web service. In this paper, we considered the QoS and CoS in the evaluation process to solve the problem of existing researches related to the web service selection and used PROMETHEE(Preference Ranking Organization MeTHod for Enrichment Evaluations) as an evaluation method which is most suitable for the web service selection among MCDM approaches. PROMETHEE has advantages that solve the problem that a pair-wise comparison should be performed again when comparative services are added or deleted. This paper suggested a case study with the service composition scenario in order to verify the selection process. In this case study, the decision making problem was described on the basis of evaluated values for qualities from a consumer's point of view and the defined service level.

Pediococcus pentosaceus SA131 was isolated from jeotgal, is the bacteriocin producer against bovine mastitis pathogens, Streptococcus uberis E290, Enterococcus gallinarum E362, and Staphylococcus epidermidis ATCC 12228. The medium composition for pediocin SA131 production by P. pentosaceus SA131 was optimized using response surface methodology. Component of medium was studied as carbon source (glucose, fructose, lactose, glycerol, sucrose, maltose, and mannitol), nitrogen source (beef extract, yeast extract, peptone, malt extract, and tryptone), mineral and surfactant ($MgSO_4$, $KH_2PO_4$, $(NH_4)_2SO_4$, $MnSO_4$, NaCl, sodium acetate, and Tween 80). Through one factor-at-a-time experiment, glucose, fructose, yeast extract, malt extract, NaCl, $MgSO_4$, and Tween 80 were determined as the good ingredient. The effects of major factors for pediocin SA131 production were investigated by two-level fractional factorial designs (FFD). By a $2^4$ FFD, fructose, yeast extract, and $MnSO_4$ were found to be the important factors for the bacteriocin production. Subsequently, a $2^3$ central composite design (CCD) was adopted to derive a statistical model for optimizing the composition of the fermentation medium. The estimated optimum composition for the production of pediocin SA131 by P. pentosaceus SA131 was as follows; 0.13% fructose, 1% glucose, 1.8% yeast extract, 2.58% $MnSO_4$, 0.2% NaCl, and 0.2% Tween 80. The pediocin production under optimized medium was increased to 1,000 AU/mL, compared to the 400 AU/mL in MRS medium.

Web services are being recognized as the efficient way to integrate the distributed applications on the web based on the web standards such as SOAP, WSDL and UDDI. Recently, BPEL4WS is suggested as a standard integration model language for web services to integrate them efficiently. The recent studies of web service integration are focused on the comparability among the services, process identification and tracing, and automation, However, little or no effort has been dedicated to the reusability, extensibility on the business process integrated services and how to allocate the services dynamically, So, in this paper, we propose how to increase the reusability and extensibility of integrated structure when services are integrated using BPEL4WS, and how to allocate and use the services dynamically. Also, we propose the framework of the composition of web services for the efficient use of suggested integrated structure.
