  • This paper considers service deployment and priority optimization for multiple service-oriented applications sharing reusable services, which are deployed as multiple instances in the cloud. In order to handle variations in the workloads of the multiple applications, service instances of the individual reusable services are dynamically provisioned in the cloud. Also service priorities for each application in a particular reusable service are dynamically adjusted. In this paper, we propose an analytic performance model, based on a queueing network model, to predict the expected sojourn times of multiple service-oriented applications, given the number of service instances and priority disciplines in individual reusable services. We also propose a simple heuristic algorithm to search an optimal number of service instances in the cloud and service priority disciplines for each application in individual reusable services. A numerical example is also presented to demonstrate the applicability of the proposed performance model and algorithm to the proposed optimal decision problem.

  • Objective: This paper discusses how service design is related to two well-known disciplines, interaction design and cognitive systems engineering, which are applied to the design of software, websites and mobile phones, and the design of control room of nuclear power plants and cockpit control, respectively. Background: Service design has been spotlighted recently due to its promisingness to service industry. Successful cases of service design are widely shared among designers. Service design, however, is treated as practice rather than a discipline. Method: It was discussed that it is important to consider the interaction between customers and services as in interaction design, and some domains are complex enough and have functional limitation as in cognitive systems engineering. Results: Models and design tools of the disciplines are introduced and applied to service design practices. Conclusion: It was concluded that service design has the characteristics of both interaction design and cognitive systems engineering.

  • Humanity's sustainability issues have long been discussed, and the World Commission on Environment and Development (WCED) in 1987 proposed the concept of sustainable development and became a global issue. In September 2015, we announced the latest goals for sustainable development at the UN's 70th General Assembly to address social problems and achieve mature economic growth. In order to achieve social, economic and environmental sustainability goals, parallel development of various disciplines is required. However, existing disciplines are limited in supporting sustainable development due to inherent nature. This study proposes to revitalize service science research as a way to overcome limitations of existing studies, and suggests that sustainable development goals can be achieved through convergence with service science and existing disciplines. Modern economic societies need the evolutionary development of individual disciplines because the paradigm shifts from the existing tangible environment to the intangible environment, the boundary between industries is dismantled, and the boundaries between disciplines disappear. In particular, sustainable development goals require a convergent approach, so convergence service science research is useful. In this study, we analyze economics, business administration, pedagogy, sociology which are representative of related to sustainable development and suggest the necessity of introduction of service science. Through this study, the development of service science and interdisciplinary research in existing academic fields will be activated.

  • Recently, M/G/1 priority queues with a finite buffer for high-priority customers and an infinite buffer for low-priority customers have applied to the analysis of communication systems with two heterogeneous traffics : delay-sensitive traffic and loss-sensitive traffic. However, these studies are limited to M/G/1 priority queues with finite and infinite buffers under a work-conserving priority discipline such as the nonpreemptive or preemptive resume priority discipline. In many situations, if a service is preempted, then the preempted service should be completely repeated when the server is available for it. This study extends the previous studies to M/G/1 priority queues with finite and infinite buffers under the preemptive repeat-different and preemptive repeat-identical priority disciplines. We derive the loss probability of high-priority customers and the waiting time distributions of high- and low-priority customers. In order to do this, we utilize the delay cycle analysis of finite-buffer M/G/1/K queues, which has been recently developed for the analysis of M/G/1 priority queues with finite and infinite buffers, and combine it with the analysis of the service time structure of a low-priority customer for the preemptive-repeat and preemptive-identical priority disciplines. We also present numerical examples to explore the impact of the size of the finite buffer and the arrival rates and service distributions of both classes on the system performance for various preemptive priority disciplines.

  • Since the service organizations have been moving towards digitization across the world, there is a wide range of technological innovations that have been integrated within the service firms, especially in banking services. As such, Internet banking is one of the innovative services that have reshaped the traditional banking activities, particularly in Bangladesh. In line with this, the research is designed to examine the Internet banking adoption based on five variables: perceived usefulness, perceived ease-of-use, trust, social influence, and perceived enjoyment, and the study also explores differences among respondents on these study variables based on gender and academic disciplines. The study has selected university students as study samples as they are the prospective customers to use Internet banking. Sample size in the research is 300, and a well-designed questionnaire was distributed to collect data. SPSS is used for statistical analysis. The research used ANOVA test to capture any difference on variables based on gender and academic disciplines. The findings indicate that male students in business have more intention to adopt Internet banking and preference for ease-of-use than female students, and business students will be more favorably inclined to adopt Internet banking service than students in other academic disciplines.

  • This study analyzes the past and present of service science research as a central discipline that will lead a new economy and society, and presents a guide for future research. In the 21st century, service research has developed into a new discipline that is different from the existing service studies. Service science is a discipline that collectively refers to all research related to services. This study analyzes this development process and suggests the direction of future service science research. First, we analyze the research before the birth of service science, an early model of service studies. And the early research on the birth of service science is analyzed. Through this process, the service science framework that expanded and developed the initial service science is analyzed. We introduce each field of service science, which is a new innovation of the existing academic system from a modern perspective, and analyzes the structure of the service philosophy that is the basis of independent academic fields. And we suggest the future direction of service science research. The direction of paradigm innovation research of existing individual disciplines is presented first. As an example, innovation from existing business administration to service business administration is introduced. We also suggest a new economic and social system research direction that requires the convergence of multiple academic fields. Finally, we present a direction for multidimensional, broad-based convergence research. We suggest that the future of service science can be the process of reverting back to integration and convergence, centered on humans and the world, of the disciplines that have continued to diverge in the history. We present a model in which all disciplines are reintegrated into service science as the Eastern and Western spirits converge.

  • This paper introduces the Korea Citation Index (KCI) and also some macro statistics of KCI. KCI started service since 2008 by the National Research Foundation of Korea (NRF), but the data has been gathered from 1998. Our findings are as follows: heavy reliance on books in humanities, but papers as the main reference in all other disciplines. Impact factor is an increasing trend in all disciplines. Social science has the highest impact factor among all fields. In some fields even in science and engineering areas, there are more KCI papers than Korean JCR papers and impact factors of the KCI are higher than JCR. As for the distinction between nationally and internationally fields or journals, some disciplines in social science are clearly nationally oriented. NSE journals listed in both KCI and JCR, however, are not clear in terms of impact factor, but clear in terms of the numbers of papers.

  • The purpose of this study is to examine the direction of the students' satisfaction improvement by comparison of related disciplines of undergraduate management information systems (MIS) majors. MIS is one of the academic disciplines that have become important as the demand for manpower for new industries in the 4th industrial revolution. We surveyed 3rd and 4th grade undergraduate students in the departments of management information systems, business administration (BA), computer engineering (CE) of C university. The results revealed that the students' satisfaction was influenced by the ability of the professor, the curriculum development, and the curriculum operation factors. Especially, it was found that the curriculum operating factors among the three departments had greater effect on the students' satisfaction. If the education environment is improved considering curriculum operating factors and the administrative and service factors and that are important in the CE departments, it will be helpful for the students' satisfaction improvement of MIS.

  • Objective: To analyze the characteristics and trends of scientific publications on thyroid ultrasound (US) from 2001 to 2020, specifically examining the differences among disciplines. Materials and Methods: The MEDLINE database was searched for scientific articles on thyroid US published between 2001 and 2020 using the PubMed online service. The evaluated parameters included year of publication, type of document, topic, funding, first author's specialty, journal name, subject category, impact factor, and quartile ranking of the publishing journal, country, and language. Relationships between the first author's specialty (radiology, internal medicine, surgery, otorhinolaryngology, and miscellaneous) and other parameters were analyzed. Results: A total of 2917 thyroid US publications were published between 2001 and 2020, which followed an exponential growth pattern, with an annual growth rate of 11.6%. Radiology produced the most publications (n = 1290, 44.2%), followed by internal medicine (n = 716, 24.5%), surgery (n = 409, 14.0%), and otorhinolaryngology (n = 171, 5.9%). Otorhinolaryngology and internal medicine published significantly more case reports than radiology (p < 0.001, each). Radiology published a significantly higher proportion of publications on imaging diagnosis (p < 0.001 for all) and a significantly lower proportion of publications on biopsy (p < 0.001 for all) than the other disciplines. Publications produced by radiology authors were less frequently published in Q1 journals than those from other disciplines (p < 0.005 for internal medicine and miscellaneous disciplines and < 0.01 for surgery and otorhinolaryngology). China contributed the greatest number of publications (n = 622, 21.3%), followed by South Korea (n = 478, 16.4%) and the United States (n = 468, 16.0%). Conclusion: Radiology produced the most publications for thyroid US than any other discipline. Radiology authors published more notably on imaging diagnosis compared to other topics and in journals with lower impact factors compared to authors in other disciplines.

  • Product development and marketing that appeal to consumer emotions are important as shown by a variety of product and service industries that integrate fashion and arts into product design and marketing through collaboration. This study attempted to analyze the patterns in the collaborations of fashion and arts across industry disciplines. A total of 278 collaboration cases reported in news articles were collected from internet databases. Cases were categorized into 5 disciplines of fashion-fashion, arts-arts, fashion-arts, fashion-other industries, and arts-other industries, with each category analyzed in frequency distribution and collaboration type along with related partner and industry characteristics. Collaborations with other industries were observed more than internal ones, and individuals (rather than firms) were more involved in collaborations. Though the collaboration characteristics were different by partner category and sub-category, by individual or firm, and by related industries, a variety of collaborations integrating fashion and arts into product design and development, a new brand launching, product line extension, and co-marketing were observed across product and industry disciplines. The study also described fashion and arts that were integrated into consumer life styles.
