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.

We present a new MDA-based Mobile-IPv6 multicast routing algorithm for wirelese service operators to offer Mobile-IP over IMT-2000 service under IMT-2000 network by taking advantage of the existing infrastructure for IMT-2000 multimedia application services. The extended IMT-2000 system architectures use an PDSNs (i.e. IWFs), and the home network (i.e. Internet) backbone and intermediate network are composed of ATM entities. A key feature of the new protocol is the use of MDA(Multicast Delivery Agent) to reduce delivery path length of the multicast datagram. We show that proposed protocol is efficient in terms of various performance measures such as multicast traffic load, multicast related handoff, and average routing length when we implement it using the Mobile-IPv6. Particularly, the number of tunneling and average routing length of datagram are reduced relatively, the multicast traffic load is also decreased.

Faster, safer and cheaper mailing of the postal matter is essential for surviving in the competitive market of home-delivery service. In the past, the domestic delivery business has been nu by only a few number of companies. But more and more number of companies including medium size ones are participating in the business, and the competition is getting severe. This paper proposes a method to select the optimal location of mail distribution centers that minimally connect the local mail centers of some major cities in Korea using the Steiner Tree theory, which is about connecting a finite number of points with a minimal length of paths and has been used in the distribution system optimization and optimal routing of the transmission lines of the electric power system. By using Steiner Tree theory in finding the best location of the postal delivery hub, we may expect the reduction of transportation cost and the increase of profit, resulting in acquiring the superior position in the competitive delivery business. It is expected that we may use the Steiner Tree theory in finding the best location of the electric power substation for the nott higher EHV(extreme high voltage) transmission network.

The purpose of this study was to estimate the influence of the determinants for home meal replacement (HMR) purchase frequency before and after COVID-19. Multinomial logistic regression was applied to the 2018~2020 Consumer Behavior Survey for Food data from the Korea Rural Economic Institute (KREI). Gender, age, number of households, monthly income, use of eating out, delivery and takeout order service, HMR food safety concern, the frequency of cooking at home, grocery shopping, and eating alone were applied as the explanatory variables to explain HMR purchase frequency. The results are as below. Compared to the previous year, the growth rate of HMR purchase frequency in 2020 was relatively high, indicating that the COVID-19 outbreak acted as a catalyst. Unlike in 2018 and 2019, there was no statistical difference in the HMR purchase frequency between single- and multi-person households in 2020, with indicating multi-person households began to emerge as one of the major HMR consumption groups. Unlike 2018, the 2020 HMR purchase frequency showed a statistically positive relationship with those of grocery shopping and eating alone. There was a positive relationship between the frequency of eating out/food delivery orders and HMR purchases. The more often cooking at home occurred, the less HMR food was purchased.

The purposes of this research were 1) to investigate the characteristics of the meal service participants; 2) to evaluate the food service utilization of the elderly; 3) to identify major factors that affect food service satisfaction of the participants in Chungchongbuk-Do. For doing this, 309 subjects were selected and the survey research method was adopted. The characteristics of the meal service participants were similar to the characteristics of general elderly population in Korea. The public assistant recipients were under representative in this sample, that is, most of elderly people who participated in meal service consisted of non public assistant recipients. It meant that meal service was not provided to low-income elderly people. The health status of the elderly people was stable to be able to attend to the meal service organizations. The most important reason to use a meal service was to see their friends. It showed that meal services played an important role to provide support systems to the elderly people in community. Thus, meal services should be provided to the elderly people with social services. In order to analyze the factors influencing food service satisfaction, multiple regression analysis was employed. The results showed that physical activity, contact with friends who met in meal service program, and the number of social services were the important variables to predict meal service satisfaction in this study. These findings contributed to a better understanding of developing a meal service planning. Several improvement strategies were recommended to provide effective meal services. First, socio-economical characteristics of the elderly should be considered to provide appropriate services. Second, meal services should be provided to the elderly people with social services. Third, home delivery meal services should be available to the home-bound elderly.

As the various A/V devices and home networks are delivered to users, home networks are changing to an entertainment network. It is expected that the required network bandwidth and the amount of usage of media content in home entertainment networks will be increased. Although the access networks and home networks becoming a high speed network, there remains the problems for QoS-guaranteed media content transfer in home networks. Also, in the home network, there can be network traffic caused by applications like video conferencing, video telephone, and VoIP(voice over IP) as well as inner network traffic of home network. Since media content transfer requires the real-time delivery, it is very important and basic requirement that is to transfer media content to A/V device user wants while keeping the media quality. Even though there are many middleware protocol for home networking, they provide basic device discovery and control or simple functions for QoS-guaranteed media content transfer that are not enough to provide QoS-guaranteed media transfer service that user wants. Thus, in this paper, we propose the technique based on UPnP(universal plug and play) protocol for QoS-guaranteed media content transfer in the home network. The proposed technique is compatible with UPnP and can be used with UPnP as additional functions. In this paper, we utilize VideoLAN application to verify the proposed technique. We add the additional modules that support the proposed technique's function to VideoLAN and we verify the its functions through various test scenarios.

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.

Purpose: This study was designed to define the roles, tasks, and activities of home visiting nurses aimed at enhancing the quality of nursing care under the long-term care insurance regulation for the elderly introduced on July 1, 2008 in Korea. Methods: A review of domestic and foreign literature was used to formulate the proposed roles, tasks, and activities of visiting nurses, which were subsequently modified and complemented by the agreement of home visiting nurse experts and acceptance of 127 nurses. Data was collected from 04 June - 17 September 2008 and analyzed concerning frequency and percentile using SPSS ver. 15.0. Results: The established functions of home visiting nurses were direct nursing service provider, case manager, patient educator, decision maker, care coordinator, and research worker. These functions involved 27 different tasks and 167 activities. Conclusion: The roles, tasks, and activities of visiting nurses, established based upon the guidelines of the Long-term Care Insurance Act for the elderly, were verified for their applicability by nurses involved in home care delivery. These parameters will provide a useful tool in developing an assessment to enhance the quality of home-based care for the elderly in Korea.

Hospice Care is the best way to care for terminally ill patients and their family members. However most of them can not receive the appropriate hospice service because the Korean health delivery system is mainly be focussed on acutly ill patients. This study was carried out to clarify the situation of hospice in Korea and to develop a hospice care delivery system model which is appropriate in the Korean context. The theoretical framework of this study that hospice care delivery system is composed of hospice resources with personnel, facilities, etc., government and non-government hospice organization, hospice finances, hospice management and hospice delivery, was taken from the Health Delivery System of WHO(1984). Data was obtained through data analysis of litreature, interview, questionairs, visiting and Delphi Technique, from October 1998 to April 1999 involving 56 hospices, 1 hospice research center, 3 non-government hospice organizations, 20 experts who have had hospice experience for more than 3 years(mean is 9 years and 5 months) and officials or members of 3 non-government hospice organizations. There are 61 hospices in Korea. Even though hospice personnel have tried to study and to provide qualified hospice serices, there is nor any formal hospice linkage or network in Korea. This is the result of this survey made to clarify the situation of Korean hospice. Results of the study by Delphi Technique were as follows: 1.Hospice Resources: Key hospice personnel were found to be hospice coordinator, doctor, nurse, clergy, social worker, volunteers. Necessary qualifications for all personnel was that they conditions were resulted as have good health, receive hospice education and have communication skills. Education for hospice personnel is divided into (i)basic training and (ii)special education, e.g. palliative medicine course for hospice specialist or palliative care course in master degree for hospice nurse specialist. Hospice facilities could be developed by adding a living room, a space for family members, a prayer room, a church, an interview room, a kitchen, a dining room, a bath facility, a hall for music, art or work therapy, volunteers' room, garden, etc. to hospital facilities. 2.Hospice Organization: Whilst there are three non-government hospice organizations active at present, in the near future an hospice officer in the Health&Welfare Ministry plus a government Hospice body are necessary. However a non-government council to further integrate hospice development is also strongly recommended. 3.Hospice Finances: A New insurance standards, I.e. the charge for hospice care services, public information and tax reduction for donations were found suggested as methods to rise the hospice budget. 4.Hospice Management: Two divisions of hospice management/care were considered to be necessary in future. The role of the hospice officer in the Health & Welfare Ministry would be quality control of hospice teams and facilities involved/associated with hospice insurance standards. New non-government integrating councils role supporting the development of hospice care, not insurance covered. 5.Hospice delivery: Linkage&networking between hospice facilities and first, second, third level medical institutions are needed in order to provide varied and continous hospice care. Hospice Acts need to be established within the limits of medical law with regards to standards for professional staff members, educational programs, etc. The results of this study could be utilizes towards the development to two hospice care delivery system models, A and B. Model A is based on the hospital, especially the hospice unit, because in this setting is more easily available the new medical insurance for hospice care. Therefore a hospice team is organized in the hospital and may operate in the hospice unit and in the home hospice care service. After Model A is set up and operating, Model B will be the next stage, in which medical insurance cover will be extended to home hospice care service. This model(B) is also based on the hospital, but the focus of the hospital hospice unit will be moved to home hospice care which is connected by local physicians, national public health centers, community parties as like churches or volunteer groups. Model B will contribute to the care of terminally ill patients and their family members and also assist hospital administrators in cost-effectiveness.

The aims of this study were to investigate usage status, menu preference, quality evaluation and satisfaction of home-delivered meal box for children from low-income families in Chungcheongbuk-do, Korea. A total of 320 children and their guardians who had received home-delivered meal boxes participated in 2015. A total of respondents (62.2%) were children and teenagers, and 37.8% were guardians. The 47.7% of children and 43.8% of guardians were using the home delivery service more than one year. Most of the children and guardians answered 'eat almost', 'eat all meals' served meal box, 75.3%, 81.8%, respectively. After receiving the meal box at home, 35.2% of children consumed meals within 1~2 hours, whereas 32.8% of the guardians were ate within 2~6 hours. It was founded that 'throw away leftovers' was the highest and followed 'give it others' in a way to treat leftovers. The results of preference survey on meats, seafood, showed that 'chicken nugget' (4.07) and 'stir-fried fish cake with vegetable' (3.63) were the highest points for children, whereas 'grilled LA beef ribs' (3.98) and 'stir-fried anchovies' (3.72) were the highest point for guardians. 'Seasoned leaves marinated in soy sauce' was the highest preference among vegetables and another dish for respondents. Frozen products were the most preferred types of meal boxes on the menu. In the quality evaluation of home-delivered meal box, although satisfaction with service and packaging of the meal box were high, the satisfaction of food quality was relatively low.
