Physical Web과 Eddystone은 하나의 통합된 어플리케이션에서 URL을 통해 각각의 서버에서 서비스를 구현하는 방식으로 단 하나의 어플리케이션으로 작동할 수 있다. 하지만, 각 BLE 디바이스의 역할을 위해서는 BLE 디바이스에 맞는 어플리케이션이 따로 존재해야만 한다. 이를 극복하기 위해 BLE 디바이스 컨트롤 서버를 통해 각 제조사와 Beacon을 연동하고 통합된 어플리케이션을 지원하기 위한 새로운 플랫폼이 필요하다. 이는 Beacon의 서비스를 위한 Push(Broadcasting)와 관리를 위한 Pull(Connection)을 모두 담당하게 해야 되며, 특히 Pull과 같은 경우에는 권한을 통해서 관리가 가능해야 한다. 이를 위해 BLE 통신에서 새롭고 안전한 통신 프로토콜이 필요하다. 이에 본 논문은 Physical Web 및 Eddystone 기반의 BLE 디바이스 컨트롤 서버에서 보안이 적용된 기기 제어를 위한 BLE 통합 인증 시스템을 제안한다.

As Internet protocol and wireless communications have developed, the number of different types of mobile services has increased gradually. Existing priority-computing schemes cannot satisfy the dynamic requirements of supporting multiple services in future wireless communication systems, because the currently used factors, mainly user priority, are relatively simple and lack relevancy. To solve this problem and provide the desired complexity, dynamic behavior, and fairness features of 3G and beyond 3G mobile communication systems, this paper proposes a novel cross-layer dynamic integrated priority-computing scheme that computes the priority based on a variety of factors, including quality of service requirements, subscriber call types, waiting time, movement mode, and traffic load from the corresponding layers. It is observed from simulation results that the proposed dynamic integrated priority scheme provides enhanced performance.

This study aims to examine the effect of integrated health and welfare(IHW) services on medical use and medical expenses in Korean Veteran Hospitals. Data on the volume of medical use and medical expenses were collected from two patient groups of 5 Veterans' Hospitals: the beneficiary group who has received IHW services and the non-beneficiary group who has not. Each group was composed of 265 patients respectively. The results of the study revealed that the volume of home nursing services, home rehabilitation services, ambulatory services have increased significantly, whereas the average length of stay, number of using emergency services, and average medical expenses have decreased after receiving integrated health services in the beneficiary group. In contrast, the non-beneficiary group showed much more increase both in the volume of inpatient and outpatient services, as well as the average medical expenses, compared to those of the beneficiary group. This results imply that the provision of IHW services have positive impacts on the enhancing the effectiveness of the medical resources utilization for the veteran patients.

Purpose : This study examined the effects of an integrated management program on physical function, cognitive function, and depression in patients with subacute stroke. Methods : A nonequivalent control group design was adopted. The participants were assigned to either the experimental group (n=20) or control group (n=23). The experimental group received an 8-week integrated management program and standard rehabilitation service (i.e., physical therapy and occupational therapy), while the control group received the standard rehabilitation service only. Physical function was measured as gait speed and balance ability using the Berg Balance Scale (BBS). Cognitive function was measured with neuro-behavioral cognitive status examination (NCSE), and depression was measured using the Beck Depression Inventory-II (BDI-II). Repeated measure ANOVA was used to determine changes in physical function, cognitive function, and depression over 8-weeks. Results : The interaction between group and time was significant, indicating that the experimental group showed improvement in gait speed, balance ability, cognitive function (linguistic ability, linguistic memory, reasoning), and a decrease in depression compared to the control group. Conclusion : These results indicate that the integrated management program developed herein was beneficial in restoring physical function, cognitive function, and depression in subacute stroke patients.

The purpose of the study is to establish priorities in integrated medicine policy. Delphi method was used in conducting a survey on integrated medicine specialists regarding the policies of integrated medicine and actions. For specialists in integrated medicine, total 17 persons selected included scholars who performed minimum one study on integrated medicine, medical staff who performing integrated medical service at institutions that implemented integrated medical care or those who were involved in creating or implementing policies on integrated medicine. The first Delphi-method survey conducted from Apr. 14 through 18, while the second survey was carried out from Apr. 21 through 25. To prioritize the policies based on the results of the mini Delphi-method survey, Analytic Hierarchy Process(AHP) was performed for 15 persons answered to mini Delphi-method from May 2 through 16, 2014. From the Delphi-method survey, four policies and 16 actions were obtained. AHP showed the first priority placed on 'Building the Infrastructure of Industrialization in the Integrative medicine' of the 4 policies and 'Developing new diagnostic and treatment instruments' was given the highest priority of the 16 actions. For implementation of integrated medicine policy, the 4 policies and the 16 actions found in this research require government support and should be urgently implemented according to its priority.

This paper describes an integrated navigation strategy for the autonomous service robot PSR. The PSR is under development at the KIST for service tasks in indoor public environments. The PSR is a multi-functional mobile-manipulator typed agent, which works in daily life. Major advantages of proposed navigation are as follows: 1) Structured control architecture for a systematic integration of various software modules. A Petri net based configuration design enables stable control flow of a robot. 2) A range sensor based generalized scheme of navigation. Any range sensor can be selectively applied using the proposed navigation scheme. 3) No need for modification of environments. (No use of artificial landmarks.) 4) Hybrid approaches combining reactive behavior as well as deliberative planner, and local grid maps as well as global topological maps. A presented experimental result shows that the proposed navigation scheme is useful for mobile service robot in practical applications.

Due to the development of information technology, Convergence and Creative Economy became hot issues. For example, products become more intelligent and services are likely to be connected and integrated around core services or provided as bundle solution. Meanwhile products and services are integrated in the context of mutual supplementation, which leads to Servitization of Products and Productization of Services in many industries. Previous studies have addressed Convergence with different terms and definitions such as Convergent, Multicategory Multifunctional Product, Clouding Service, Bundle and so on from one perspective such as consumers, suppliers or technology according to a wide range of academic approaches. Thus, this study attempted to suggest the most typical convergence products released in the convergence environment and categorize those products. Furthermore, this study has pointed out the problems in the New Product Development Framework discussed in the studies on marketing by taking the situation of the public sector into account and then suggested "New Service Development Framework in the Public Sector" that are different from traditional e-Gov. approach basically and will enable the government to create public information service and provide them to enterprises or citizens. It also emphasized the importance of Business Conceptualization Stage in the framework; argued that there is a necessity of an integrative study from the perspective of technology on the basis of the approach from the perspective of marketing and Policy such as a study of consumer behaviors, design and marketing channel and Policy Integration for the development and dissipation; and furthermore suggested the cases-the development/Diffusion of Transportation Card Service in Seoul and CFC (Call for Collaboration) in Singapore-in order to verify the framework. There is a need to supplement New Service Development Framework so it is able to reflect the distinct characteristics of the public sector from the academic perspective and be used as practical guidelines for SI (System Integration) business to shift into IT Service business. Last but not the least, this study has suggested the limitations and the directions for the future studies.
