This study aimed to identify services and social and leasure programs that will be needed for helping senior residents to be aging healthfully and comfortably in the university-based continuing care retirement community (UBRC). This study conducted case study targeting three representative university-based CCRCs in the east area of United States such as Oak Hammock (OH) at Florida state, Kendal at Lexington (KL) and The Collonades (C) at Virginia state. There were three types of services in the UBRC, which were meal services, healthcare services, and personal services. Those services were different from the level of care such as independent living, assisted living, nursing home and memory care. Meal services and personal services were very similar among three UBRC, whereas healthcare services of OH were higher level of quality and diversity than the others. The social and leisure programs were categorized in-house programs, university outreach program and intergenerational programs between residents and students attending to related university. In-house programs and university outreach program were almost similar among three UBRC, whereas intergenerational programs of OH were well organized and actively operated than the others. This study results are expected to provides essential information for the development of Korean style services and programs of university-based CCRCs in the future.

As the fast development of information technology (IT), abundant attractive alternatives have showed up and challenged to the traditional information technology (IT). Cloud services, the hottest representative among these alternatives, has attracted the attention from all walks of life. Considering the diversity of cloud services, this study attempts to find out the important factors affected on individual's switching intention from incumbent IT to cloud services mainly based on two-factor theory (switching enablers and switching inhibitors) and explore the direct influences of these factors on individual's switching intention. According to our findings, individual's switching intention to cloud services is not only positively influenced by switching enablers but also negatively influenced by switching inhibitors. All the switching enablers in this study (perceived omnipresence, perceived collaboration support and perceived compatibility of cloud services) have positively significant influences on individual's switching intention as well as the switching inhibitors (usage habit of incumbent IT and perceived risk of cloud services) have negatively significant influences on individual's switching intention. It's noteworthy that satisfaction of incumbent IT has insignificant influence on individual's switching intention in this study. Moreover, as we expected, both social influence and personal innovativeness have significant influences on the generation of individual's switching intention.

Community Wireless Networks define the next generation wireless services. Multimedia usages for financial services over community Wireless LAN (WLAN) based mesh networks require link stability. Several new services are being proposed for multimedia over WLANs. Portable Internet Services are implemented by several wireless carriers to proliferate their customer base. However, these services are still expensive and require a central telecom/wireless carrier whose monopoly and preference defines the availability of new services. Our research project identifies the usage of these critical services in public places over the financial services backbone architecture to provide efficient easy-to-use and economical services to their customers and merchants without being dependent on the central wireless carrier. The user connects to the network using his regular WLAN NIC using the Mesh Router/Bridge interconnectivity and obtains the needed multimedia and financial services from the ATM-AP Gateway, In our proposed scenario, the ATN AP-MR use AODV protocol and MR-MC is based on 802.11g/a/b IEEE standard. We use multi path routing protocols for reducing the congestion over a particular route. We demonstrate the results of our simulations and test-bed outcome to evaluate link failure rate and oversubscription factors to eliminate network congestion and non-availability of the critical financial services.

Machine-to-Machine(M2M) refers to technologies allowing both wireless and wired systems to communicate with other devices. The enhancement of wireless technologies and the reduced cost of wireless connection have contributed toward the development of M2M market. M2M market currently focuses on public sector services, As M2M can offer scalable and flexible services, M2M services are expected to be applied in various fields. However there are still some doubts on whether the demand for M2M services will be increased. This study investigates the feasibility of M2M services from the perspective of operators. Operators evaluate that M2M services will show high marketability but low profitability in general. In addition, operators predict that M2M services will show both marketability and profitability in the area of car maintenance, insurance, telematics, home and office security, shop floor maintenance, and real-time locating services for children protection. This study may offer some ideas of M2M business models based on empirical feasibility studies.

Web Services have been utilized in a wide variety of applications and have turned into a key technology in developing business operations on the Web. Originally, Web Services can be exploited in an isolated form, however when no single Web Service can satisfy the functionality required by a user, there should be a possibility to compose existing services together in order to fulfill the user requirement. However, since the same service may be offered by different providers with different non-functional Quality of Service (QoS), the task of service selection for Web Service composition is becoming complicated. Also, as Web Services are inherently unreliable, how to deliver reliable Web Services composition over unreliable Web Services should be considered while composing Web Services. In this paper, we propose an approach on a QoS-aware Web Service selection for reliable Web Service composition. In our approach, we select and classify Web Services using Decision Tree based on QoS attributes provided by the client. Service classifier will improve selection of relevant Web Services early in the composition process and also provide flexibility to replace a failed Web Services with a redundant alternative Web Services, resulting in high availability and reliability of Web Service composition. We will provide an implementation of our proposed approach along with efficiency measurements through performance evaluation.

Objectives: This paper describes an experience of implementing seamless service trials online and offline by adopting Internet of Things (IoT) technology based on near-field communication (NFC) tags and Bluetooth low-energy (BLE) beacons. The services were provided for both patients and health professionals. Methods: The pilot services were implemented to enhance healthcare service quality, improve patient safety, and provide an effective business process to health professionals in a tertiary hospital in Seoul, Korea. The services to enhance healthcare service quality include healing tours, cancer information/education, psychological assessments, indoor navigation, and exercise volume checking. The services to improve patient safety are monitoring of high-risk inpatients and delivery of real-time health information in emergency situations. In addition, the services to provide an effective business process to health professionals include surveys and web services for patient management. Results: Considering the sustainability of the pilot services, we decided to pause navigation and patient monitoring services until the interference problem could be completely resolved because beacon signal interference significantly influences the quality of services. On the other hand, we had to continue to provide new wearable beacons to high-risk patients because of hygiene issues, so the cost increased over time and was much higher than expected. Conclusions: To make the smart connected hospital services sustainable, technical feasibility (e.g., beacon signal interference), economic feasibility (e.g., continuous provision of new necklace beacons), and organizational commitment and support (e.g., renewal of new alternative medical devices and infrastructure) are required.

In the new era of IoT, a deeper and richer understanding of consumer characteristics is required to accelerate the acceptance and popularization of different types of smart home services (e.g., hedonic or utilitarian smart home services). In the current research, self-regulation systems are considered one of the consumer characteristics. Therefore, this research examines the role of consumers' regulatory focus (promotion focus vs. prevention focus) in their responses to smart home services, particularly when they are not familiar with the services. Specifically, this research examines whether consumers' attitudes toward utilitarian/hedonic smart home services differ according to their regulatory focus, particularly when they are not familiar with the services. The results indicate that consumers who are not familiar with smart home services have more favorable attitudes toward hedonic smart home services when they are promotion-focused (vs. prevention-focused). In contrast, there is no significant difference in their attitudes toward utilitarian smart home services between promotion- and prevention-focused consumers. Our findings imply that regulatory focus may be an effective marketing and segmentation tool in promoting new smart home services and facilitating low-familiarity consumers' receptiveness to the services.

The importance of trade in services has been increasing day by day, but the research on it is insufficient so far in terms of basic information, statistics, influence, industrialization and so on. To foster of professional trader in services, we need curriculums, textbooks and training centers like academy or college in advance. We have well developed curriculums for trade in goods since 1960's in Korea, so we can transfer the trade in goods' curriculum to trade in services. There are some differences between trade in goods and trade in services basically, but we can borrow a lot of idea from trade in goods in terms of basic framework like international economics, international business and international commercial transactions. This study propose the basic framework for trade in services' curriculum. First, trade in services economics handle the basic concept, statistics, characteristics, theories etc. Second, trade in services business treat the global companies to expand their business to global market, so characteristics of service companies, marketing plan and strategies and so on. Third, international commercial transaction of trade in services concentrate for procedures and contracts in terms of formation, implementation and finish of contract. Finally, Services industries can be a future strategic industry to any contries, so there are some national and corporates' strategy for expanding their business. This study acts on the initial idea for curriculums of trade in services, so I am looking forward to many criticism and development from another researchers to develop the model curriculums and textbook for education of specialized trader in services.

The purpose of this study is to determine the level of recognition of home care services and to provide basic data for implementation of home care services. Data collection was carried out between December 2004 and January 2005 by surveying 88 nurses and 40 physicians working at a general hospital and 28 physicians working at different clinics in the Seoul metropolitan city area. The results of this study were as follows: 1. Home care services were recognized by $94.2\%$ of nurses, $77.5\%$ of physicians and $92.9\%$ of clinic physicians. The main sources of information for most of them were medical and nursing journals. 2. The percentages of staff regarding find home care services as necessary for the institutions were $88.6\%$ of nurses, $74.4\%$ of physicians and $57.1\%$ of clinic physicians. All of them anticipated that home care services would maintain 'continuous care' and 'long-term patient care'. 3. The percentages of staff willing to refer their patients to home care were $95.5\%$ of nurses, $100\%$ of physicians and $87.1\%$of clinic physicians. However, only $7.1\%$ of clinic physicians were willing to refer actively. 4. Most nurses and physicians replied that a majority of test-related services is suitable for home care services. However, among medication-related services, intravenous injections were not suitable for home care services. Among treatment-related services, most nurses and physicians replied that Levin tube feeding, oral and nasal suction, simple dressing, perineal care, and enema were suitable for home care services, but incision and drainage, and tracheostomy tube change were not suitable for home care services. In conclusion, for the implementation of hospital-based home care services, it is necessary to educate nurses and physicians on the present condition and precedent at other hospitals.
