With the arrival of 3rd generation cellular networks it is expected that a lot of new cellular services will be available to the mobile users like video calling, location based services etc. Similarly MBMS is one such service which is targeted for 3G mobile users for viewing talk shows, live sport events etc. One shall view this service like a small portable T.V being carried by the mobile user. The user watches the programs of his liking by joining if he wishes. In this paper we focus on the possible UTRAN architectures to provide MBMS service within UMIS networks. The paper primarily focuses on the requirement aspect, notification aspect and the mobility aspect. The paper lists many options for notifications and elaborates on them in terms of pros and cons. In the end the paper conclude with an UTRAN architecture for MBMS service which meets the requirements of this service as well as makes minimum changes to the existing UTRAN architecture while attempting to save terminal power for this service.

In an upcoming ubiquitous era, humankind will live in a ubiquitous space, where everything is connected through communication network. In this ubiquitous space, a ubiquitous robot, which can be used by anyone for any service through any device and any network at anytime and anywhere in a u-space, is expected to be required to serve seamless and context-aware services to humankind. In this paper, we introduce the ubiquitous robot, and define three components of the ubiquitous robot. The first one is "SoBot" which can be connected through the network in anywhere with environment recognition function and communication ability with human. The second one is "EmBot" which is embedded into environments and mobile robots and has localization and certification function with sensor fusion. The last one is "Mobile Robot" which serves overall physical services. This paper also introduces KAIST ITRC-Intelligent Robot Research Center that pursues the implementation of the ubiquitous robot.

With the ever-increasing frequency of public sector and smalls-cale industries going live on the internet in developing countries, their security of which, while crucial, is often overlooked in most cases. This is especially true in Government services, whilst essential, are poorly monitored if at all. This is due to lack of funds and personnel. Most available software which can help these organizations monitor their services are either expensive or very outdated. Thus, there is a need for any developing country to develop a networking monitoring system. However, developing a network monitoring system is still a challenge and expensive and out sourcing network monitoring system to third party is a security threat. Therefore, in this article we propose a method to anonymize network logs and outsource networking monitoring system to third-party without breach in integrity of their network logs.

Recently, SDN and NFV technology have been developed actively and provide enormous flexibility of network provisioning. The future network services would generally involve many different types of services such as hologram games, social network live streaming videos and cloud-computing services, which have dynamic service requirements. To provision networks for future services dynamically and efficiently, SDN/NFV orchestrators must clearly understand the service requirements. Currently, network provisioning relies heavily on QoS parameters such as bandwidth, delay, jitter and throughput, and those parameters are necessary to describe the network requirements of a service. However it is often difficult for users to understand and use them proficiently. Therefore, in order to maintain interoperability and homogeneity, it is required to have a service abstraction layer between users and orchestrators. The service abstraction layer analyzes ambiguous user's requirements for the desired services, and this layer generates corresponding refined services requirements. In this paper, we present our initial effort to design a Smart Service Abstraction Layer (SmSAL) for future network architecture, which takes advantage of machine learning method to analyze ambiguous and abstracted user-friendly input parameters and generate corresponding network parameters of the desired service for better network provisioning. As an initial proof-of-concept implementation for providing viability of the proposed idea, we implemented SmSAL with a decision tree model created by learning process with previous service requests in order to generate network parameters related to various audio and video services, and showed that the parameters are generated successfully.

This study conducted a survey of residents living in senior housing in the outskirts of Tokyo metropolitan area where the demand for senior housing is rising. The study examined their motives for moving into senior housing, criteria for housing selection, and their degree of satisfaction with living in senior housing. The analysis results are as follows. First, the majority of respondents gave reasons for moving into senior housing such as wanting to live with more comfort and freedom and not wanting to live with their spouse any longer. Second, in choosing conditions their senior housing, the respondents put priority on the credibility of a management company, and they also valued easy accessibility to the place. In addition, they wanted the environment to be suitable for a stroll. Third, as for the degree of satisfaction with the living facilities, the respondents expressed dissatisfaction with kitchen and storage areas most frequently. This suggests that it is necessary to consider the physical characteristics of elderly people when planning senior housing by securing kitchen facilities that support independent living and provide more storage space. Fourth, in terms of the level of satisfaction with residential services, the respondents were quite content with their consulting services, response to their complaints, and the surrounding environment. However, they were less satisfied with events organized by the management company, or the in-house medical service.

Mankind has been attempting to live a happy and safe family life in a residential space. Due to the advent of the mobile phone in the 1990s and the smart phone in the 2000s, when the information and communication age came, human life has been innovatively changed. The revolution of human civilization led to the Neolithic Revolution and the Iron Age, followed by a smart phone revolutionizing human life, and the revolution faces with the era of info-communication, smart phones became a daily life and the fourth industrial revolution. The fourth industrial revolution is an era of info-communication technology (ICT), creating a new paradigm across human life through technological developments such as artificial intelligence (AI), IoT, big data, mobile, and cloud. The smart home is actively researched in a direction to support the overall human life as a representative future residential culture paradigm. However, the study considering the needs according to the lifestyle, functional characteristics of each living space and human lifestyle of the Phono Sapiens era where smart phones live like daily life was relatively insufficient. In addition, research on smart home service design should be considered from the apartment residential space planning stage. Therefore, this study has significance in suggesting the direction of research on human-centered smart home service design considering the characteristics of each living space and resident's life-style in the smart phone era.

Objectives: The challenge of an increasing elderly population has coupled with everpresent social concerns in Korea. A major problem in health center for the frail older people is that medical, healthcare, and welfare services are often fragmented in terms of providers and settings without appropriate coordination. The purpose of this study was to investigate the need of health center-based integrated healthcare services and its related factors for the elderly. Methods: A total of 110 elderly people who had visited at a county Health Center were interviewed using a self-administered questionnaire from November to December, 2005. The questionnaire consists of five domains according to the Program of All-inclusive Care for the Elderly. Results: Respondents had high need (total mean score with the 5-point Likert-type sacle: 3.67) of health center-based integrated healthcare services including home visiting service (mean: 4.08), chronic disease care service (mean: 4.06), and transportation service (mean 4.05). According to the results of hierarchical multiple regression analysis, among three regression models the magnititude of the variance of full model that is explained by the need of welfare-domain service was significantly larger than two reduced model. Income was a significant variable in increasing the need of health care and welfare services. Conclusions: This study suggests that the health center-based integrated healthcare services for the elderly must be continuously developed and provided for the health promotion and improved the quality of life of the elderly who live in rural area in Korea.

This study was conducted as a survey to find out middle-aged persons's housing preferences for a future elderly housing and to grasp background characteristics of persons influencing the preferences and the effect of elderly's aging situations on the changes of their preferences. A sample of 300 middle-aged people was selected purposely from parents of university students living in Gwang-ju city. Questionnaires were administered to parents by students and analysed with SPSS Windows 10 program. Middle-aged persons's housing preferences were differed according to elderly's aging situations, in the case of healthy situation, they tended to prefer to stay present house without their children in irrespective to couple or single, whereas in the case of unhealthy situation, they tended to prefer to live with their children. and couples showed preferences for planned housing for the elderly and singles showed preferences for elderly housing facilities with care services. The most important characteristics of elderly housing among middle-aged people was a places where they can enjoy leisure and provide home-help services, located in the suburbs. Also middle-aged persons were likely to prefer to a green spaces such as garden, path for walking, and madang for the elderly housing. Needs for community care services (NCCS) were required above the average. Among the items of NCCS, a visiting medical examination was the most demanding, and a visiting nursing services, a emergency calling bell, and home repairs were sequently followed in the level of needs. The characteristics of the elderly housing which preferred to and needs for community care services were influenced by middle-aged persons's age, gender, subjective evaluation of economic abilities, tenure status, the cost of living, and the size of housing. This findings suggests that it must to be considered to develop various types of the elderly housing depending on socioeconomic status.
