Purpose: We report here on two cases of calcific tendinitis at the origin of the common extensor tendons of the forearm. Materials and Methods: A 42 year-old female complained of left elbow pain and flexion contracture. After obtaining the simple radiographs and MRI, surgical excision of the calcific deposits was done under the diagnosis of calcific tendinitis. A 25 year-old female complained of right elbow pain and a limited range of motion. Simple radiographs showed a calcific deposit just distal to the lateral epicondyle, and then she was managed with extracorporeal shock wave therapy. Results: The pain disappeared completely and both patients regained a full range of motion after treatments. Conclusion: Calcific tendinitis at the origin of the common extensor tendons of the forearm should be included in the differential diagnosis of the lateral elbow diseases that cause pain and a limited range of motion.

Users are provided infrastructure such as CPU, memory, network, and storage as IaaS (Infrastructure as a Service) service on cloud computing environments. However storage instances cannot support the maximum storage capacity that SQL servers can use, because the capacity of instances provided by service providers is usually limited. In this paper, we propose a method of securing mass storage capacity for SQL servers by sharing network disks with limited storage capacity. We confirmed through experiments that it is possible to secure mass storage capacity, which exceeds the maximum storage capacity provided by an instance with Amazon EBS on Amazon EC2 Windows environments, and it is possible to improve the overall performance of the SQL servers by increasing the disk capacity and performance.

This paper, in order to minimize the ground waiting time of an Air tanker, the queuing theory, that is, a queue that calculates the waiting time under single-server and multi-server situations, was used in the study. Since the national budget and resources are limited, the unlimited increase of the logistics support service team is limited. Therefore, the number of logistic support service teams that can adaptively control the ground waiting time according to the wartime preparation stage or war environment was calculated. The results of this study provide a stipulated standard for calculating the optimal number of air tanker logistic support service teams of the Air Force, providing a basis for the logistical commander to assign logistic support service teams to each stage from peacetime to wartime.

IoT (Internet of Things) systems are based on heterogeneous hardware systems of different types of devices interconnected each other, ranging from miniaturized and low-power wireless sensor node to cloud servers. These IoT systems composed of heterogeneous hardware utilize data sets collected from a particular set of sensors or control designated actuators when needed using open APIs created through abstraction of devices' resources associated to service applications. However, previously existing IoT services have been usually developed based on vertical platforms, whose sharing and exchange of data is limited within each industry domain, for example, healthcare. Such problem is called 'data silo', and considered one of crucial issues to be solved for the success of establishing IoT ecosystems. Also, IoT services may need to dynamically organize their services according to the change of status of connected devices due to their mobility and dynamic network connectivity. We propose a way of dynamically composing IoT services under the concept of WoT (Web of Things) where heterogeneous devices across different industries are fully integrated into the Web. Our approach allows developers to create IoT services or mash them up in an efficient way using Web objects registered into multiple standardized horizontal IoT platforms where their resources are discoverable and accessible. A Web-based service composition tool is developed to evaluate the practical feasibility of our approach under real-world service development.

Although the telecommunications service industry has become a basic infrastructure component of the information and communication technology (ICT) industry, it is now losing its reputation as a cash cow due to achieving a saturation of service subscribers, especially in South Korea. With the exception of improving network speeds, network operators are experiencing difficulties in creating new innovations. Therefore, new innovations for the telecommunications service industry should be identified in conjunction with government policies for industry promotion. To examine the innovative capabilities of a specific industry, innovation system theories were used as a framework for research. However, existing innovation systems are limited with regard to explaining the openness of relationships and user participation which are general properties of the ICT industry. Moreover, as sources of innovative activity, additional values such as financial support and collaboration are more appropriate. This study presents a new innovation system based on innovation values. We analyze the telecommunications service industry and prioritize the importance of telecommunication policies within South Korea. An in-depth interview with experts based on the innovation system framework is conducted first. Next, innovation factors derived from the interview are applied within an analytic hierarchy process (AHP), leading to a prioritization of innovation factors for the telecommunications service industry.

The present study, first, reviews theoretically previous studies about the concept and quality of services as well as tools to measure the quality. Second, it reviews theoretically previous studies about the concept and quality of special services as well as tools to measure the quality. According to the results of reviewing previous studies on service quality, it is considered that the variance among several researchers concerning the measurements of service quality is affected significantly by factors such as the procedures of data collection and analyses utilized in the studies. In addition, the fact that dimensions are different, or some dimensions are not independent, is highly likely to be based on the unique characteristics of business categories, in addition to research procedures. Accordingly, when measuring service quality in future studies, it may be desirable to adapt measuring tools partially for the characteristics of each service category, and to generalize the adjusted tools over the specific category. Especially studies on the quality of special service have been carried out in limited scope so far. Thus, it is required to develop and refine comprehensive and appropriate criteria and detailed questions to measure the quality of fashion education service. Furthermore, studies are necessary with regard to relations among relevant factors such as customers' satisfaction and perception on education service quality after they experience the services.

This paper introduces a prototype smart home environment that is built in the research building to demonstrate the feasibility of a robot-assisted future home environment. Localization, navigation, object recognition and handling are core functionalities that an intelligent service robot should provide. A huge amount of research effort has been made to make the service robot perform these functions with its own sensors, actuators and a knowledge base. With all complicated configuration of sensors, actuators and a database, the robot could only perform the given tasks in a predefined environment or show the limited capabilities in a natural environment. We started a smart home environment for service robots for simple service robots to provide reliable services by communicating with the environment through the wireless sensor networks. In this paper, we introduce various types of smart devices that are developed for assisting the robot in the environment by providing sensor and actuator capabilities. In addition, we present how the devices are integrated to constitute the smart home environment for service robots.

The growth of Bandung's tourism industry has had a massive impact on the hotel sector. Most tourists visiting Bandung are domestic tourists and tend to be modest spenders fitting the profile of a mid-market (2/3 star) hotel guest. As competition has increased mid-market hotels have come under pressure from upmarket (4/5 star) and budget hotels committed to cutting prices. There is also competition with the mid-market hotel sector, which means that the 2/3 star hotels have to keep innovating in order to remain competitive. This study uses the Service Quality framework to describe customer expectations and identify gaps in hotel services. A questionnaire survey of 105 local tourists who had stayed in 2/3 star hotels in Bandung showed that the most important dimension is responsiveness, following by reliability, assurance, tangibles and empathy. Thus we conclude that local tourists' primary expectations are that hotels will deliver the service they have promised, be responsive to guests' needs and comply with service standards. Furthermore, these findings validate the earlier prediction that comparing 2/3 star hotel with 5/4 start hotel, the customers are having preliminary knowledge on facilities limitation and friendliness. Tourists using 2/3 star hotels tend to be prepared to accept limited facilities and less friendly staff service.
