We analyze $MAP_1,\;MAP_2$/G/1 finite queues with service scheduling function dependent upon queue lengths. The customers are classified into two types. The arrivals of customers are assumed to be the Markovian Arrival Processes (MAPs). The service order of customers in each buffer is determined by a service scheduling function dependent upon queue lengths. Methods of embedded Markov chain and supplementary variable give us information for queue length of two buffers. Finally, the performance measures such as loss probability and mean waiting time are derived. Some numerical examples also are given with applications in telecommunication networks.

Recent development of information technologies produces a lot of community services. Social Network Service is one of the community services on the world wide webs. In the Social Network Service, a user can register other users as friends and enjoy communication through a virtual message. Previous researches show a few social service methods using manually generated tagging. However, the manual social tagging is not widely used in many social network services. Moreover, they do not consider ubiquitous computing environment. We propose a recommendation method for social service using contexts in ubiquitous environment. Our method scores documents based on context tags and social network services. Our social scoring model is computed by both a tagging score of a document and a tagging score of a document that was tagged by a user's friends.

Purpose: In this study consumers' preference for housing for elderly people was analyzed as well as the recognition by elders of silver town facilities, and their preference for service provided by silver town. The study was done to provide basic data for the development of silver town facilities that are low in cost and high in efficiency. Methods: A sample research was used in this study to analyze the understanding of old age, silver town, and service preference. Results: First, interest and intention to live in silver town was very positive, however low cost was also preferred and that is quite different to current silver towns of Korea. Second, women have more understanding of, requests for, and intention to move into silver town facilities than men. Women's demands for silver town facilities must be reflected in the development strategy of silver towns. Third, the most important part of activating silver town facilities is price strategy. Government political support is required in order to keep silver town move-in costs affordable. Fourth, silver towns must function as total service complex towns. Conclusion: This study is meaningful as efficient operation of silver town is suggested rather than facility degradation to achieve price reduction. This result is important to the development of silver towns based on consumer preference, as it suggests a development direction that is focused on securing differentiated services and programs.

As online services become more and more popular due to the development of IT, non-face-to-face transactions are continuously increasing rather than face-to-face transactions. The personal identity proofing service(PIPS) based on the alternative method of the resident registration number is used for the purpose of confirming the identity of the other party on the Internet. However, in the case of the current PIPS, the personal information of the PIPS user is excessively provided to the online service provider. As a result, privacy problems of online users, shortage of choice of information providing options, and lack of differentiation of authentication methods are becoming problems. Therefore, this paper proposes a method to improve the PIPS based on the current resident registration number alternative method and to provide a method to differentiate the provision of excessive personal information. In the proposed method, we analyze trends and current status of overseas online PIPS in order to provide a method of providing differentiation of personal information and proposes an effective improvement method applicable to domestic.

Purpose: This study aimed to confirm the mediating effect of work-life balance organizational culture in the relationship between work-life balance and quality of nursing service for clinical nurses. Methods: Participants included 224 nurses from four hospitals located in D city. Data was collected from 3 to 21 August 2020 using a self-report questionnaires. Descriptive statistics, t-test, one-way ANOVA, Scheffé test, and Pearson's correlation coefficient were used for analysis. The mediating effect was assessed by Baron and Kenny's three-step hierarchical regression analysis and bootstrapping methods. Results: There were significant relationships between work-life balance and work-life balance organizational culture (r=.45, p<.001), work-life balance and quality of nursing service (r=.18, p=.005), and work-life balance organizational culture and quality of nursing service (r=.34, p<.001). Also, work-life balance organizational culture (β=.32, p<.001) showed a total mediating effect on the relationship between work-life balance and quality of nursing service.

In recent years, research at the Environmental Microbial and Food Safety Laboratory (EMFSL), Agricultural Research Service (ARS) has focused on the development of novel image-based sensing technologies to address agro-food safety concerns, and transformation of these novel technologies into practical instrumentation for industrial implementations. The line-scan-based hyperspectral imaging techniques have often served as a research tool to develop rapid multispectral methods based on only a few spectral bands for rapid online applications. We developed a newer line-scan hyperspectral imaging platform for high-speed inspection on high-throughput processing lines, capable of simultaneous multiple inspection algorithms for different agro-food safety problems such as poultry carcass inspection for wholesomeness and apple inspection for fecal contamination and defect detection. In addition, portable imaging devices were developed for in situ identification of contamination sites and for use by agrofood producer and processor operations for cleaning and sanitation inspection of food processing surfaces. The aim of this presentation is to illustrate recent advances in the above agro.food safety sensing technologies.

In the present emerging global economy, as the focus is shifted from manufacturing to service sector, the efficiency of service operations is crucial for the county's sustainable growth and development. As one of the fastest growing service sector industries in South Korea, the call center has become an inevitable part of customer service for most companies. Despite of the strategic importance of the call center, there has been no empirical study on the efficiency of call center service operations in the literature. The main purpose of this study is to evaluate the technical efficiency of call center services so as to not only identify the current status of call center service operations, but also suggest ways to improve service operations efficiency. For this purpose, we apply a non-parametric efficiency measurement method, DEA (Data Envelopment Analysis), to domestic call centers in order to compare their relative efficiency. Based on DEA evaluations, we provided specific directions for the inefficient call centers to possibly improve their operation efficiencies. It is expected that the measurement methods suggested in this study can be applied to various issues such as service KS certification, service operations management, and the productivity analysis of service personnel.
