This study was to investigate the differences of functional health status and medical service experience and needs between general and vulnerable older people in community. This study is a cross-sectional descriptive research. The data obtained through direct visit surveys from November to December 2016. The target population of the study was older people over 65 years old, the final study subjects were 444 older people residing in one district of Seoul. The chi-square test was conducted to confirm the difference in their functional health areas and medical service experiences, and the necessity of medical service utilization in accordance to the social class. In the experience of abnormality in functional health, the vulnerable older people had higher experience in cognitive function, nutrition, hydration, pain, and falling than the general older people. The rate of experience of using medical service to solve the cognitive function problem for general older people was 31.9%, higher than that of the vulnerable older people. In contrast, the medical service utilization needs of the vulnerable older people in the pain management category was significantly higher than that of the general older people. In setting policy of public medical service programs for general and vulnerable older people in community may be differentially developed based on this study. In order to improve the medical accessibility of the vulnerable older people, public medical institutions should be actively supported to overcome obstacles to medical use due to economic barriers.

The Multi-access Edge Computing (MEC) paradigm equips network edge telecommunication infrastructure with cloud computing resources. It seeks to transform the edge into an IT services platform for hosting resource-intensive and delay-stringent services for mobile users, thereby significantly enhancing perceived service quality of experience. However, erratic user mobility impedes seamless service continuity as well as satisfying delay-stringent service requirements, especially as users roam farther away from the serving MEC resource, which deteriorates quality of experience. This work proposes a deep reinforcement learning based service mobility management approach for ensuring seamless migration of service instances along user mobility. The proposed approach focuses on the problem of selecting the optimal MEC resource to host services for high mobility users, thereby reducing service migration rejection rate and enhancing service availability. Efficacy of the proposed approach is confirmed through simulation experiments, where results show that on average, the proposed scheme reduces service delay by 8%, task computing time by 36%, and migration rejection rate by more than 90%, when comparing to a baseline scheme.

This study is a methodological approach to the study of a customer experience-based Tuberculosis(TB) management service design for a local public medical institution, with the application of the service design process by the Design Council in the UK. This study designed a TB management service for a local public medical institution using the service design method which identifies and resolves TB management-related problems based on experiences of medical personnel of TB facilities as well as of TB patients. To design a TB management service for the whole process from hospitalization to discharge and then to cooperation with local communities, a team was formed with 12 TB management-related personnel. The team went through the four phases of service design process: Discover, Define, Develop and Deliver. In addition, the TB management service based on customer experience was developed that included eight services related to processes from hospitalization to discharge and cooperation with local communities. According to the study results, a service design methodology was found to be considerably effective in developing a service program that takes into account an overall circumstance of various relevant personnel as well as patients. It is suggested that further studies use a service design methodology in developing various health management service programs in need of improvement of work efficiency among relevant personnel as well as providing the best satisfaction for customers by identifying hidden needs based on their experiences.

Objectives : To examine the factors associated with the use of the prenatal care services provided by the Ministry of Gender Equality and Family by married migrant women in Korea. Methods : We employed data from the 2015 Nationwide Multiculturale Family Survey. We selected 19- to 39-year-old married immigrant women with children aged 5 years or less for the study (N=1,579). We included four predisposing factors, six enabling factors, and two need factors based on the Andersen's Health-care Utilization Model. Results : Only one third of married immigrant women(31.6%) used prenatal care service and 45.9% of them reported prenatal care service needs. Area of residence, country of birth, and Korean language proficiency were significantly associated with prenatal care service use. Further, age, country of birth, length of time in Korea, household income, and discrimination experience were significantly associated. Conclusions : Findings suggest the need to develop strategies to improve accessibility to prenatal care service use especially for married immigrant women from developing countries, low-income families, having poor Korean language proficiency or having discrimination experience.

A study on what kind of problems young consumers experience in buying and using mobile phone services with a comprehensive and consumers oriented perspective is needed. Through this acknowledgement, we investigated (i) the degree of consumer problems that young consumers experience in purchasing and using mobile phone services, and (ii) the related variables that affect experiences of this consumer problem. The parents of the teenagers were also included in the survey because they experience the same problems young consumers' experience in buying and using mobile phone services. Data were gathered through an internet survey (www.embrain.com) and a total of 699 samples from 350 parents and 349 youths using mobile phone services were analysed. The results are as follows. First, the teenagers and parents' experience level of young consumers' problems were generally high experiencing similar kinds of problems. Second, parents experienced more young consumers' problems than the teenagers in buying and using mobile phone services, especially in misuse and abuse of the phones. Third, among the teenagers, the monthly usage fee music or game usage, the number of changes in mobile phone service operators, the number of replacement mobile phones and the gender had a significant effect on consumers' problems of mobile phone services. Among the parents, the monthly usage fee, music or game usage, confirmation of the bill, and the gender of their child were significant consumer problems.

The purpose of this exploratory study was to analyze nursing role conceptions and test the relationships between nursing role conceptions and professional commitment among selected Korean nurses. Data were obtained from a convenience sample of 262 practising nurses of varying positions, education, and experience. The total sample represents a response rate of 93 percent. Subscales of Nursing Role Conceptions (Pieta, 1976) were used to measure professional, service, and bureaucratic role conceptions 1 the tool to measure professional commitment was developed by the investigator. The results of this study were as follows. 1. Professional role conception and service role conception were positively related(normative r＝ .61 : categorical r＝ .64). Bureaucratic role conception scores(32.6$\pm$4.97) were higher than professional and service role conception scores. 2. Experience was positively related to bureaucratic professional categorical role conception(r＝ .17, p＜ .01), and negatively related to bureaucratic professional role discrepancy(r＝- .12, p＜ .01). There was no relationship between experience and service role conception. This study also showed that nurses who had longer experience tended to have higher role conceptions on all three subscales. 3. Nurses with a master's degree had significantly higher professional and bureaucratic role conceptions scores. Bacealaureates graduates had the lowest bureaucratic categorical role conception scores ; associate nurses had the lowest professional categorical role conception scores. 4. Nursing supervisors and head nurses had significantly higher bureaucratic categorical role coneption scores, whereas they had lower bureaucratic normative and professional role conception scores. 5. Age and experience were positively related to professional commitment (r＝ .24, r＝ .28). Hierarchical multiple regression analyses showed that the combination of nursing role conceptions explained greater variance in professional commitment pair of the variables alone. Further research employing dynamic designs is needed to execute rigorous tests of causal models of nursing role conceptions and professional commitment. The findings of this study suggest that antecedents and moderating variables of nursing role conception and professional commitment need to be explored for further theoretical. specification and empirical evaluation.

The purpose of this study was to propose a "user experience (UX)-centered product development process" so that the product design development process using the service design process can be systematized and used in practice. In a situation in which usability research on office phones is lacking compared to general home phones, this study expands to a product-based service design point of view rather than simple product development, intending to research ways to provide user experience value through office phone design in smart office. This study focused on extracting UX-centered user needs using the service design process and developing product design that realizes user experience value. In particular, the service design process was applied to systematically extract user needs and experience value elements in the product development process and to discover ideas that were converged with product-based services. For this purpose, the "Double Diamond Design Process Model," which is widely used in the service design field, was adopted. In addition, a product design development process was established so that usability improvement plans, user experience value elements, and product-service connected ideas could be extracted through a work-flow in which real users and people from various fields participate. Based on the double diamond design process, in the "Discover" information collection stage, design trends were identified mainly in the office phone markets. In the "Define" analysis and extraction stage, user needs were analyzed through user observation, interview, and usability survey, and design requirements and user experience issues were extracted. Persona was set through user type analysis, and user scenarios were presented. In the "Develop" development stage, ideation workshops and concept renderings were conducted to embody the design, and people from various fields within the company participated to set the design direction reflecting design preference and usability improvement plans. In the "Deliver" improvement/prototype development/evaluation stage, a working mock-up of a design prototype was produced and design and usability evaluation were conducted through consultation with external design experts. It is meaningful that it established a "UX-centered product development process" model that converged with the existing product design development process and service design process. Ultimately, service design-based product design development process was presented so that I Corp.'s products could realize user experience value through service convergence.
