The purpose of this study is to investigate factors that explain the degree of need for community welfare services designed for the residents of Wonju City. For this purpose, we identify five categories of community welfare services : employment no income supporting programs, residence supporting programs, public health programs, family programs and welfare facilities for enhancing quality of life. The data come from 234 adults living in Wonju city, Major findings can be summarized as follows. Firstly, we find that participants are well aware of needs for community welfare service, and that the degree of need for public health services is the highest among the five types of welfare programs. Secondly, we find differential effects of the individual factors such as predisposing, enabling, and need, and the community factors such as quality of environmental facilities which make daily lives convenient, and residential region. Particularly, environmental facilities appear to have a strong association with high needs for the majority of welfare services. Finally, differences between urban and rural areas are still observed. These results suggest that the responsibility of Wonju city for providing diverse and adequate welfare services should be emphasized. Priorities for welfare policies based on the empirical data are also taken into consideration in the process of developing community welfare policies.

Purpose: This study identifies the relative importance of the sub - factors of initial services and continuous services using AHP (Analytic Hierarchy Process) method, and calculates the competitive index for the detailed factors. The purpose of this paper is to propose the establishment of long - term and short - term management strategy for expansion of business of food service franchise, franchisors, long - term and win - win relationship with franchisees, and rationalization of operating system. Research design, data, and methodology: The population for the survey is 92 franchisees in 46 foreign brands and 46 domestic brands in the Seoul metropolitan area (Seoul / Gyeonggi / Incheon). The survey was conducted from July 1 to August 31, 2018 through the survey agency with a telephone interview and a surveyor's direct visit. A total of 100 questionnaires were collected, but a total of 92 parts were used for analysis except 8 parts that were considered to contain false information. Using the AHP method, relative importance and competitiveness index were calculated for the details of initial services and continuous services. Results: The results shows continuous services were significantly higher for both foreign brand franchises, domestic brand franchises, and overall than initial services, This suggests that the continuous services of the affiliated franchisors has a higher relative importance than the initial services. Among the continuous services, brand reinforcement and promotion were significantly higher for both foreign brand merchants and domestic brand franchises. This can be regarded as the most important factor in brand reinforcement and promotion when selecting a food service franchisors. Conclusions: In the Standard Terms and Conditions governed by the Fair Trade Commission, the franchisors should increase the fairness by creating manuals for supporting services, especially after opening, and regularly checking whether the supporting services have been carried out like manuals since the establishment of franchisees. In addition, the Brand Strengthening and Public Relations Committee (tentative name) jointly participated by the franchisors and franchisees for the purpose of strengthening and promoting the brand, suggesting a system for transparent and efficient execution of the brand reinforcement and promotion budget and monitoring afterwards.

In the future, the ubiquitous computing environment will provide users with context-aware services, intelligently interacting with omnipresent resources and surrounding environments at any location and time. Therefore, the ubiquitous computing environment requires context-aware applications in order to gather and analyze context information in various situations. However, existing context-aware applications have mainly focused on providing services and adapting themselves to users based on user related contexts. But this environment requires not only user related contexts but also Quality-of-Service (QoS) related contexts. In this paper we propose a frame-work for supporting user-oriented QoS in ubiquitous environments. The proposed approach adopts a semantic ontology and a neural network algorithm in order to reason about explicit and uncertain contexts. We also show the possibility of applying the framework to real environments such as collaborative engineering service, automobile maintenance service and ubiquitous home service.

As the rapid incensement of the number of internet users has occurred recently, many multimedia application services have been emerging. To improve quality of service, traffic can be suggested to be classified with priority in EPON(Ethernet Passive Optical Network), which is supporting the multimedia application services. In this paper, multimedia application services treat bandwidth classifying device in serving both delay sensitive traffic for real-time audio, video and voice data such as VoIP(Voice over Internet Protocol), and nonreal-time traffic such as BE(Best Effort). With looking through existing mechanisms, new mechanism to improve the quality will be suggested. The delay performances and packet losses of traffic achieved by supporting bandwidth allocation of upstream traffic in suggested mechanism will be analyzed with simulation.

Collaborative and distributed engineering web services are emerging as a viable alternative to the traditional design and engineering process automation. Existing approaches have limitations in supporting long-running engineering transactions, automatic engineering process orchestration and choreography, synchronous and asynchronous conversation, and geometric abstraction for transmission and sharing. In this paper, we present a process-centric engineering web service methodology to overcome these limitations by utilizing BPEL-based (Business Process Execution Language) process templates and coordination broker-based conversation support. This paper discusses the synchronization of engineering web services which can be either peer-centric or process-centric to support long-running engineering transactions and conversation. The process orchestration and choreography broker works as a service dispatching and aggregation mediator for executing process templates, which enables the individual activity or the engineering process to dynamically select and invoke one of the alternative web services through the run-time process brokering. Further, the paper presents how to support collaboration over the running process using conversation policy.

This study was conducted to examine the present state, types of services, difficulties, education programs, motivation, satisfaction and attitude of hospice volunteers and also to suggest supporting programs for the volunteer. For these purposes, a questionnaire was distributed among the 200 hospice volunteers in ten hospice organizations in Daejeon and Chungcheong province. In this research, 85.5% of the respondents were women and most of them were housewives in their forties and fifties. The majority of hospice volunteers had an education background of more than high school. Christianity (94%) was the dominant religion of volunteers. Among the service area of the hospice, emotional caring, such as listening closely and establishing empathy were the most frequently done by the respondents and the next one was spiritual care. Hospice volunteers who had started with altruistic motivation show more dynamic activities in emotional, spiritual, physical caring and so on, than those with non-altruistic motivation. Most of the respondents expressed that they felt a hospice volunteer was valuable. However they had a hard time to overcome the sorrow coming from sharing empathy with the dying patients. Those who had started with altruistic motivation usually took part in two times per a week and had more positive attitude. Volunteers who had been working more than five years showed better attitude than those who had been working less than three years. The longer the voluntary services, the more positive attitude experienced by volunteers. Hospice volunteers encountered the most considerable difficulty with lack of background knowledge and their actual capability. Insufficiency of time was the next reason for the considerable difficulty of the hospice volunteer. On the other hand, those who served more than twice per week replied that lack of background knowledge and their capability were the least considerable difficulty. Insufficiency of time was the reason of difficulty for male volunteers, as well as for females under thirty and those in their forties and fifties respectively. Generally most of the hospice volunteers (70%) were satisfied with their services and they usually satisfied with physical caring, spiritual caring, hospice's family caring. The less difficulty in voluntary services, more satisfaction for the volunteers in the end. There is a positive correlation between a attitude of the hospice volunteer and frequency of voluntary services while the volunteers' difficulty affect negatively their attitude as well as the frequency of voluntary services. Most of the hospice volunteers want to have more education about basic skills, volunteer's attitude and role, spirituality, the way of attending on the hospice and so on. Most of them considered discussion and sharing different cases as the most effective method. They also wish to had more supporting programs for the hospice volunteers(in the order of their needs) such as regular events, newsletters, personal concern, social meetings among the volunteers, insurance and minimum expenses. Based on the study results, more programs should be run in order to activate the voluntary services regardless of their gender and education background. A continuous practical supporting policy and education programs are required in order to provide special education and training courses considering every field of voluntary services. Expanding the role of the volunteers allows them more opportunities to take part in voluntary services and th activate participation. It is necessary to establish a new hospice system as a part public medical system, which can not only facilitate the voluntary services for a hospice but also enhance professional hospice volunteers. Finally, experts are needed to operate the voluntary services effectively.
