Objectives: This study is based on Public Care Service for Chronic Diseases in Incheon Metropolitan City featuring Health-Point Service. It is objective to evaluate whether the service could improve self-management ability of hypertension and diabetes patients. Methods: The knowledge about diabetes and hypertension, which can be improved by educational intervention, is considered as one of the most important factor for self-management ability. While the education service have been conducted, 194 patients who have been diagnosed as hypertension and diabetes within 3 months were included. They completed questionnaires two times within 4 months period, which give information about the knowledge, service registration and education experiences. For further inspection, 396 patients who had been diagnosed formerly were studied by cross-sectional analysis. Results: Regardless of service registration or educational intervention, there wasn't statistically meaningful difference between the initial and the follow-up assessments on the knowledge. However, when investigating formerly diagnosed patients, educated patients had better knowledge on hypertension compared with non-educated patients and registered patients, educated patients had the better knowledge on diabetes compared with non-registered patients, non-educated patients. Additionally, analyzing each questions, educated patients got higher grades in questions about definition of hypertension, diabetes managements which they can practice in daily lives. Conclusions: It is probable that long-term service registration and education experiences could improve the knowledge and self-management ability.

Purpose: This is a retrospective secondary data analysis study based on real-world data to analyze the level of nursing care needs of patients in a comprehensive nursing care service ward, and identify factors influencing nursing needs. Methods: Study participants included patients admitted to two comprehensive nursing care service wards at a tertiary general hospital located in Gyeonggi-do, Korea. After obtaining permission from the health and medical information team of the target hospital, data were collected from their electronic medical records. Nursing care needs were measured using seven items on nursing activity and four items on daily living activities developed by the National Health Insurance Service (NHIS). The collected data were analyzed using the SPSS version 29.0 with frequency and percentage, mean and standard deviation, minimum and maximum values, t-test, ANOVA, Pearson's correlation coefficients, and multiple linear regression. Results: The level of nursing care needs of patients in comprehensive nursing care service wards was found to be higher for patients with pressure sores (β=.33), older patients (β=.26), patients who underwent procedures (β=.15), patients with present guardians (β=.15), and patients with more comorbidities (β=.10). The total explanatory power was 51.0%. Conclusion: It is necessary to accurately identify patients' nursing care needs and provide nursing care according to priority by considering the characteristics of patients in comprehensive nursing care service wards.

Existing wireless access (mobile) routers are based commonly on the network address and port translation (NAPT) technique which permits simultaneously sharing a subscriber's connection to the network with multiple users. However, the NAPT architecturally makes the users invisible on the network side, thus becoming a user-oriented connection technique. In this paper, we propose a novel service provider-oriented unlicensed nomadic access relay station (WiNNERS) for helping wireless broadband network service providers to make their business more lucrative by accommdating unlicensed band users as subscribers into their network. The WiNNERS offers service providers the capability to directly manage each of the unlicensed band users at the network side. This direct management allows the service providers to flexibly and simply handle QoS, access control, and billing for each user. In order to distinguish each of the unlicensed band users the WiNNERS constructs a virtual tunnel from each user's terminal to the network access router using connection identifiers which is defined for service flow management within the WiBro system, Consequently, our proposed service provider-oriented relay station can be included into the WiBro network system with minimum modifications.

IT skills might be just a product for people without disabilities; however it can be "another sense" that is able to give the disabled the same social abilities as non-disabled people. Library services are necessary to help disabled people have access to information. The effectiveness of the library services for the disabled depends on the level and the size of library. If 10% of the total domestic population couldn't participate in their social activities, it must be a huge individual at the same time national loss. This paper will look into supporting technologies and services for the reading disabled through literature researches and visiting domestic and international libraries. Based on this analysis, this paper suggests development plans for enhancing domestic situation. We are sure that our suggestions can contribute to give a long-term service development strategy for improving the reading disabled people's information accessibility.

The current Navigation System for the Visually Impaired Person has a short and limited communication distance and can't receive enough information from Visually Impaired Person to assist directly. In addition, because the path is dangerous and incomplete for the Visually Impaired Person, moving with White Stick is still inconvenient and dangerous. To solve this problem we implement communication that can send and receive video, voice, location information between the Visually Impaired Person's Smart Portable Navigation System Development and assistant's PC.

With the rapid development of the Internet of Things(IoT) technology recently, multi-access edge computing(MEC) is emerged as a next-generation technology for real-time and high-performance services. High mobility of users between MECs with limited service areas is considered one of the issues in the MEC environment. In this paper, we consider a vehicle edge computing(VEC) environment which has a high mobility, and propose a task migration algorithm to decide whether or not to migrate and where to migrate using DQN, as a reinforcement learning method. The objective of the proposed algorithm is to improve the system throughput while satisfying QoS(Quality of Service) requirements by minimizing the difference between queueing delays in vehicle edge computing servers(VECSs). The results show that compared to other algorithms, the proposed algorithm achieves approximately 14-49% better QoS satisfaction and approximately 14-38% lower service blocking rate.

Purpose : This study can provide various implications for the franchisors to expand activities related to franchise support or to develop andoperate an education program for foodservice franchise owners. Research design, data, and methodology : For those purpose, first, the literatureand literature related to the competency of domestic franchise owner were collected and reviewed through the Korea Education and Research Information Service (RISS). Second, the questionnaire was prepared based on the theoretical basis prepared through previous studies. Based onthe foodservice franchise owner's competency model presented by Kim & Lee (2019b), 13 franchise owner's competencies were marked with both 'What is' levels and 'What should be' levels. Therefore, the total questionnaire consists of 26 questions. Third, questionnaires were distributed and collected. This study used data from 55 surveys which were gathered from foodservice franchise owners in Seongnam-si. SPSS 25.0 was used to analyze the collected survey data. Descriptive and frequency analysis were conducted to analyze the demographic characteristics of the study subjects. Next, we conduct a t-test to analyze the difference between the level of 'What is' competencies by the franchise owners and the level of 'What should be' competencies. Descriptive statistics were used to derive the priorities of the 'What should be' competencies. The Locus for Focus model was used to derive the priorities of the required competencies. Result : Four competencies of team leadership, teamwork and cooperation, customer service, technical·professional·managerial expertise were found to be the first to be developed. Conclusions : The conclusions of this study are as follows. First, teamwork and cooperation competnecy, and team leadership competency, which are derived from the core competencies of foodservice franchise owners, are among the leadership competencies required as managers of organizations. Second, customer service competency and ttechnical·professional·managerial expertise competency derived from the core competencies of restaurant franchise owners belong to the job competencies. Third, the results of this study suggest that the foodservice franchisors will be able that will serve as a baseline to support the foodservice franchisors and franchise owners for sustainable mutual growth by encouraging their will and encouraging them to create results.
