The purpose of the study is to develop the indicator and scale for evaluating the service environments of archives and to assess the physical service environments of National Archives of Korea (NAK), and then to suggest the alternatives to improve the current service environments on the basis of the results of evaluation. To achieve the purpose, the study designed three research phases: first, to develop the indicator and scale to measure the current service environments by merging universal design indicators and various standards of NAK for establishing facilities and environments on the basis of the barrier-free authentication indicators; second, to evaluate the current service environments of NAK with the newly developed scale; finally to suggest alternatives to improve the current environments on the basis of the evaluation findings. The study found that current service environments of NAK have critical limits on the areas and facilities to provide direct archival information services to users such as reference service desks, showrooms, education rooms, seminar rooms, etc. On the basis of the results, the study suggested the alternatives and further studies for making barrier-free service environments of archives.

The robot has recently emerged as a factor in the daily lives of humans, taking the form of a mechanical pet or similar source of entertainment. A robot system that is designed to co-exist with humans, i.e., a coexistence-type robot system, is important to be "it exists in various environments with the person, and robot system by which the interaction of a physical, informational emotion with the person etc. was valued". When studying the impact of intimacy in the human/robot relationship, we have to examine the problems that can arise as a result of physical intimacy(coordination on safety in the hardware side and a soft side). Furthermore, We should also consider the informational aspects of intimacy (recognition technology, and information transport and sharing). This paper reports the interim results of the research of a system configuration that enhances the physical intimacy relationship in the symbiosis of the human and the robot.

This study was to investigate the dffects of a color reversal visual perceptual training program on spastic cerebral palsied children's figure-ground discrimination disabilities and to investigate the difference between the control group and experimental group. Subjects of the study were composed of children with spastic cerebral palsy whose age varied from five to seven years old, whose I.Q. was over 70 and whose P.Q. was over 70. Implication of this study can be summarized as follows; First, Perceptual training and speech training programs should be emphasized to improve the preparative ability of spastic cerebral palsied children. Problems of perception cerebral palsied children are concerned with figure-ground discrimination disability. Second, Though it was demonstrated that color reversal visual perceptual training program can be effective through the prestudies and this study, more researches should be made to apply this kind of theory in real education environments. More interest in different color forms for training of cerebral palsied children should be taken. Third, Reprecations of the study should be considered with modified group identities(age, I.Q., P.Q.).

Purpose : The purpose of this study was to identify the effects of circuit class training on the performance of locomotor tasks in chronic stroke. Methods : The study included 45 patients with chronic stroke randomly divided into experimetal group and control group. Both groups participated in exercise classes three times a week for 8weeks. The experimental group had 10 workstation of circuit class designed to improve walking. The control group practiced fitness exercises by equipment in health center. Walking performance was assessed by measuring walking speed(timed 10-meter walk and TUG), GAITRite analysis and peak vertical ground reaction force through the affected foot during walking. Results : The experimental group demonstrated significant improvement(p<.05) compared with the control group in 10-meter walking and vertical ground reaction force after training. The experimental group showed significant improvements in the walking velocity and cadence by GAITRite system(p<.05). Conclusion : Task- oriented circuit class training leads to improvements in locomotor function in chronic stroke. Further studies are necessary to occur in usual environments to improve walking performance.

Breast cancer is the most frequently diagnosed cancer primarily affecting women and negatively impacting the individuals, families, and the health care system. Despite the well-known benefits of exercise for breast cancer survivors, rate of physical activity declines during adjuvant therapy and may not return to pre-diagnosis levels. In addition, low levels of adherence to exercise have been observed in this cohort. The challenge is to identify strategies that are effective in promoting exercise adherence. Several of the studies use social cognitive theory as a theoretical framework to design exercise interventions that encourage adherence. Within and without this framework, they have implemented interventions within the home and gym-based environments. Strategies used to encourage adherence to exercise programs and which are readily implemented in most situations have included distribution of print materials and pedometers, as well as recommendation from the oncologist. Other strategies that may be less feasible have included provision of trainers, gym memberships, regular phone-calls, and psychologist-lead stress management sessions.

In this paper, we investigate physical layer security for multiple decode-and-forward (DF) relaying underlay cognitive radio networks (CRNs) with fixed transmit power at the secondary network against passive eavesdropping attacks. We propose a simple relay selection scheme to improve wireless transmission security based on the instantaneous channel information of all legitimate users and the statistical information about the eavesdropper channels. The closed-form expressions of the probability of non-zero secrecy capacity and the secrecy outage probability (SOP) are derived over independent and non-identically distributed Rayleigh fading environments. Furthermore, we conduct the asymptotic analysis to evaluate the secrecy diversity order performance and prove that full diversity is achieved by using the proposed relay selection. Finally, numerical results are presented to verify the theoretical analysis and depict that primary interference constrain has a significant impact on the secure performance and a proper transmit power for the second transmitters is preferred to be energy-efficient and improve the secure performance.

The purpose of this study is to identify the homelike design characteristics of elderly housing facility. To investigate what the preference of physical design characteristics are, interview was done by unstructured questionnaire to 30 middle aged and middle income group housewives living in Seoul. It was identified that preferred homelike physical characteristics of the houses were composed of 4 themes, housing types, building appearences and garden, floor plan and natural and social environments of its location. Their desirable housing standard was amenity which is the highest level of home environment. In their later life, they wanted to live in vicinity of Seoul to enjoy cultural benefits of the city and active outdoor activities in sunny, natural suburban environment. They liked a spacious, clean and bright color with natural material furnishings. Each architectural design expression of 4 themes was suggested.

Among the building types in which behavioral issues play, the largest role are institutional environments. Such setting share a number of important characteristics ; they serve specific population (e.g. the ill, the elderly , '||'&'||' inmates) : they are directed toward specific social behavioral objectives(e.g medical care, education , '||'&'||' rehabilitation); and they are "Total institution" in which residents spend all of there time. The basic concepts and theories of environment-behavior studies are of direct relevance in understanding such social institutions. In this study, I have examined the relationships between waiting and the specific conditions of the hospital experience. More specifically, this is a study of visitors (outpatient) within the context of the hospital , and the physical setting designated for their use in the outpatient waiting room. Environment behavior studies, with its commitment to individual behavior and the physical environment might well be a particularly way by which a study of waiting rooms can demonstrate the power of this approach and its integrative among disciplines.

Compared with traditional itinerary planning, intention-oriented itinerary recommendations can provide more flexible activity planning without requiring the user's predetermined destinations and is especially helpful for those in unfamiliar environments. The rank and classification of points of interest (POI) from location-based social networks (LBSN) are used to indicate different user intentions. The mining of vehicles' physical trajectories can provide exact civil traffic information for path planning. This paper proposes a POI category-based itinerary recommendation framework combining physical trajectories with LBSN. Specifically, a Voronoi graph-based GPS trajectory analysis method is utilized to build traffic information networks, and an ant colony algorithm for multi-object optimization is implemented to locate the most appropriate itineraries. We conduct experiments on datasets from the Foursquare and GeoLife projects. A test of users' satisfaction with the recommended items is also performed. Our results show that the satisfaction level reaches an average of 80%.

Recent improvements on the quality, fidelity and availability of biometric data have led to effective human physical activity detection (HPAD) in real time which adds significant value to applications such as human behavior identification, healthcare monitoring, and user authentication. Current approaches usually use machine-learning techniques for human physical activity recognition based on the data collected from wearable accelerometer sensor from a single wearable smart device on the user. However, collecting data from a single wearable smart device may not provide the complete user activity data as it is usually attached to only single part of the user's body. In addition, in case of the absence of the single sensor, then no data can be collected. Hence, in this paper, a continuous HPAD will be presented to effectively perform user activity detection with mobile service infrastructure using multiple wearable smart devices, namely smartphone and smartwatch placed in various locations on user's body for more accurate HPAD. A case study on a comprehensive dataset of classified human physical activities with our HAPD approach shows substantial improvement in HPAD accuracy.
