Purpose: Previous evaluation studies of the visiting nursing program explained an average change of the participants' health status, without considering socio-ecological characteristics and their impacts. However, these factors must affect individual health problems and lifestyles. For effective and appropriate community based programs, the Geographical Information System(GIS) can be utilized. GIS is a computer-based tool for mapping and analyzing things that happen on earth, and integrates statistical analysis with unique visualization. The purpose of this study was to evaluate visiting nursing care and to advocate the usefulness of planning and evaluating visiting nursing programs using Exploratory Spatial Data Analysis(ESDA) with GIS technology. Methods: One hundred eighty-four elderly participants with cerebrovascular risk factors who lived in 13 areas of one community received visiting nursing care. The data analyzed characteristics of pre-post change and autocorrelation by ESDA using GIS technology. Results: Visiting nursing care showed an improvement in the participants' lifestyle habits, and family management ability and stress level, while the improvements were different depending on the regions. The change of family management ability and stress level correlated with neighborhoods (Morgan's I=0.1841, 0.1675). Conclusions: Community health providers need to consider the individual participant's health status as well as socio-ecological factors. Analysis using GIS technology will contribute to the effective monitoring, evaluation and design of a visiting nursing program.

Owing to our rapidly aging society, accessibility evaluation to enhance the ease and safety of access to indoor and outdoor environments for the elderly and disabled is increasing in importance. Accessibility must be assessed not only from the general standard aspect but also in terms of physical and cognitive friendliness for users of different ages, genders, and abilities. Meanwhile, human behavior simulation has been progressing in the areas of crowd behavior analysis and emergency evacuation planning. However, in human behavior simulation, environment models represent only "as-planned" situations. In addition, a pedestrian model cannot generate the detailed articulated movements of various people of different ages and genders in the simulation. Therefore, the final goal of this research was to develop a virtual accessibility evaluation by combining realistic human behavior simulation using a digital human model (DHM) with "as-is" environment models. To achieve this goal, we developed an algorithm for generating human-like DHM walking motions, adapting its strides, turning angles, and footprints to laser-scanned 3D as-is environments including slopes and stairs. The DHM motion was generated based only on a motion-capture (MoCap) data for flat walking. Our implementation constructed as-is 3D environment models from laser-scanned point clouds of real environments and enabled a DHM to walk autonomously in various environment models. The difference in joint angles between the DHM and MoCap data was evaluated. Demonstrations of our environment modeling and walking simulation in indoor and outdoor environments including corridors, slopes, and stairs are illustrated in this study.

This paper explores into the potential contribution of welfare science and technology(WST) to meeting the challenges of ageing. Drawing on the literature about gerontechnology, this paper considers the application of scientific knowledge for welfare of an aging population. WST for the improvement of the daily functioning of the elderly people can not only prevent, delay or compensate for the declines or impairments of coginitive and physical functions (by assistive technology) but also enhance personal ability to overcome problems either by supporting the person's abilities (by supportive technology) or by changing the environment (by public welfare technology). This paper draws attention to a paradigm change in the conceptualization of disability and its ramifications for the role of technology and aging. A range of approaches such as Barrier-Free design, Universal Design points to new directions of WST in which products and services are devised to improve the quality of life for all people, and hence enhancing the socio-economic vitality. It is suggested that the future of welfare science and technology will be based in large measure on its goal to reduce or prevent individual and structural lag in the relationships between people and their environments. Addressing issues of the broader physical and social environment will emphasize the goal of prevention and the view that environmental needs for aging population are changing over time.

The existing smart farm technology has been systematized for the mass production rather than the consumer. There are many problems such as economical aspect to apply to actual rural environment due to aging. The purpose of this study is to apply smart farm technology based on the applicability of population aged in rural areas. Due to the heat wave, the crops in general greenhouse cultivation facilities suffered from damage such as sunlight damage. To minimize such damage, adjust the temperature and humidity environment or install a light-shielding film. However, the workers in the rural areas are aging and the elderly who are farming alone have a lot of difficulties in doing so. In the case of people with weak physical strength, there is a danger that they may lead to safety accidents when carrying heavy loads. In this paper, we propose 'Smart Palm capable of automatic transportation function', applying small smart vehicles that follow workers to existing smart farms to improve and prevent these problems. It is a smart farm that performs the control functions of the existing smart greenhouse environment, installs the rail for each trough, and has a vehicle that follows the worker. The smart app can directly control the greenhouse and the vehicle remotely manually.

This study aims to design, develop the impact of a high school course in practical problem- focused teaching plan which will enable students to deal with an aging society, and prepare well for the aging by looking at issues the elderly face. This study set a target of analyzing the 2007 revised curriculum manual to develop instructor-led teaching and learning plans for 'Successful aging preparation'. Five common subjects were reframed on a practical problem basis through factor analysis of preliminary research regarding aging education for teenagers and the 2007 revised curriculum and textbooks of Technology Home Economics, and Human Development. The practical problem was 'What do we need to do to Successfully live an independent life in aging?', and the subjects studied to answer this question were the aging society and population changes. the nature of the elderly, aging preparation, care of the elderly, and welfare services for the elderly. These five subjects were grouped under the main categories of The Aging Society. Understanding the Elderly, and aging Preparation. The ultimate objective of the lessons was, through critical reasoning, to inquire into the causes of current problems the elderly face so that teenagers can understand aging societies and the elderly, and prepare for a Successful aging. Another objective was to seek reasonable alternatives for teenagers as they prepare for Successful and independent aging, and increase their problem-solving abilities in choosing the best course of action by considering the ripple effect of consequences of each of those alternatives. The practical problem-teaching lesson plans consisted of five classes on practical reasoning instruction. This study suggests that new high school curricula should include lessons on preparation for aging so that students can deal successfully with our aging society.

Application of WBAN technology in medical field facilitates the prevention of diseases by collecting the vital signs remotely. It also enables to prevent the accidental emergency situation in advance plus long-tem monitoring of patients with chronic diseases such as heart diseases, hypertension, or the elderly and infirm. For emergency patients, major vital signal information collected by the 'Sensing' should have the top priority and such information should be transferred as promptly as possible without competition. In addition, when an emergency occurs to a patient, a priority mechanism is necessitated for a urgent message to get through to the final destination. However, LR-WPAN IEEE 802.15.4 technology does not consider such emergency message handling features. To deal with aforementioned issues, the IEEE 802.15.4 super frame protocol structure has been designed for stable transfer of emergency information in WBAN environment in this study, and alternation to super frame structures have been made, allowing GTS(Guaranteed Time Slot) can be used first at CFP (Contention Free Period) by reserving the resources in advance and prioritize the emergency signals. NS-2 has been utilized for the performance test and analysis.
