This study proposes proportions of functional areas in the ward of general hospitals, which are derived from 5 big university hospitals in order to establish the ward area standard for hospital design. The results of this paper are as follows. First, functional areas of hospital ward are composed of bedroom area, nursing area, training area, service area, and common area. Of course common area can be divided into first common area and secondary common area. The first common area(inter departmental common area) includes lobbies, elevator lobbies, corridors, restroom, and mechanical shafts. The secondary common area means the common area within special department such as ward or radiology department. Second, a standard method of calculating ward areas has been proposed: the standard is based on the center line of the wall between functional areas. Third, the proportions of 6 functional areas in ward are suggested.

Purpose: The purpose of the study was to compare level of functional independence and its correlates among community-dwelling older adults in rural areas between South Korea and the United Sates. Methods: The study employed a comparative and correlational design. Data were collected from 198 community-dwelling older adults in rural areas (South Korea=100, & US = 98). Functional independence, cognitive function, obesity and general characteristics were measured. Results: From both countries, approximately fifteen percent of older adults living independently had cognitive problems without any treatments. Among Korean older adults functional independence was associated with a number of chronic diseases and aging while in the United States the participants had a negative correlation with obesity and aging. Conclusion: For Korean older adults in rural areas, nurses should focus on monitoring older adults' abilities to manage chronic illness and designing self-management programs while in the United States the focus should be on healthy lifestyle programs about exercise and diet to increase functional independence.

Amongst various analytic methods of internal structure of city, the factor analysis method which uses O-D matrix data has some merits and characteristics compared to other methods. 1) It is possible to find one certain interaction and flow pattern between traffic zones with in a city through reanalyzing O-D data which is too complex to grasp specific meaning or pattern of flow systems. 2) It can be easily visualized the traffic flow pattern by using adequate graphic techniques, and also can clarify the functional areas whose interaction linkages are significantly strong enough between each other. In this study, the taxi traffic O-D data between 42 traffic zones in Kwang-ju city was reanalyzied by varimax rotated factor analysis methods. As a result, four factors that have significant level factor loading (over 0.5 ) and factor score (over 1.0) were sorted out. so to speak four different functional areas were clarified in Kwang-ju city, of the West, the East, the south, and the North functional areas whose interaction linkages are significantly strong enough between each other. In the study, the taxi traffic O-D data between 42 traffic zones in Kwang-ju city was reanalyzied by varimax rotated factor analysis methods. As a result, four factors that have significant level factor loading (over 0.5) and factor score 9over 1.0) were sorted out. so to speak four different functional areas were clarified in Kwang-ju city, of the West, the East, the South, and the North functional area, then these four functional areas are almost coincided with citizen's general conception of community division and administrative district. Accordingly the factor analysis methods using traffic data seems to proved to be very accurate and useful analytic instruments for analyzing flow pattern and clarifying functional areas of city, and believed to provide basic informations and criteria for practical urban land use planning and transportation planning.

On the basis of morphological and functional studies, it is now established that there exist multiple motor representation areas in the frontal lobe of subhuman primates. Recent development of analysis on cerebral critical organization in human subjects, utilizing novel techniques of PET and MRI, provides evidence of corresponding motor areas. Each area has its unique sources of inputs from the thalamus and from other parts of the cerebral cortex. To understand functional roles of these multiple motor areas, it is necessary to study neural activity while subjects are performing a variety of motor tasks. In view of high accuracy in spatial and temporal resolution, the analysis of single cells in relation to specific aspects of motor behavior remains to be a powerful research technique. It is with this technique that a number of novel concepts on functional roles of multiple motor areas have been proposed.

Although the availability of home care rehabilitation services have been greatly increased since community-based rehabilitation was introduced to Korea, there is still a dearth of studies investigating the performance level of ADL (activities of daily living) for the physically disabled in the rural areas. The purposes of this study were to investigate the ADL performance level of disabled persons living at home in the rural areas of Wonju city, Korea, using FIM (functional independence measure) and to identify the specific areas of the ADL to be trained or evaluated by physical therapists or occupational therapists. 298 disabled people were interviewed by 10 physical therapy students. Analysis of the interviews indicated: 1) Forty seven point seven percent of the respondents were elderly-disabled persons whose ages were 61 years old or above, and 69.5% of respondents has the history of chronic disability period of 5 years or more. 2) FIM score of bathing, and stairs climbing showed severe dependent trend 3) FIM scores of self-feeding, urination, defecation, and comprehension ability were mildly dependent. These results revealed that functional evaluation/treatment for discharging from hospitals to the rural areas should be emphasized on the specific ADL performance areas such as bathing, and stairs climbing.

본 연구는 지방지역에서 주간선도로 및 보조 간선도로의 기능을 수행하도록 규정된 일반국도의 수행기능을 통계적 방법으로 유형화하고, 각 유형별 교통특성 규명에 의한 일반국도의 적정 설계기준을 제안하였다. 전국의 도로망에서 일반국도가 수행하는 기능은 크게 3가지로 유형화할 수 있음을 통계적 방법으로 검증하였으며, 각 유형별 도로 구간의 교통특성 조사 결과, 당초 간선도로로 건설된 일반국도가 그 역할을 충분하게 수행하지 못하는 것으로 판단할 수 있었다. 이러한 문제점의 개선 대안으로 일반국도가 간선도로로서의 역할을 수행할 수 있도록 기능별 설계기준의 차별화와, 목표통행속도 개념을 반영한 부속시설 정비 기준을 제안하였다.

Purpose: In this study, we provide a way to assess even a slight effect of exercise on trunk-muscle activity. Materials and Methods: Seven healthy male participants (mean age, 24.7 ± 3.2 years; height, 171.2 ± 9.8 cm; and weight, 63.8 ± 11.9 kg) performed 15 sets of an exercise with 20 repetitions of 90° hip and right-knee flexion while lying supine. The exercise intensity was measured using the 10-point Rating of Perceived Exertion Scale after the first and 15th sets of exercises. Although cross-sectional areas and functional T2 mapping using ultrafast imaging (fast-acquired muscle functional magnetic resonance imaging, fast-mfMRI) have been proposed for imaging to evaluate exercise-induced muscle activity in real time, no previous studies have reported on the evaluation of trunk-muscle activity using functional T2 mapping. As a method for assessing trunk-muscle activity, we compared functional T2 mapping using ultrafast imaging (fast-mfMRI) with cross-sectional areas. Results: Although the muscle cross-sectional areas were increased by the exercise, there was no significant difference at rest. On the other hand, for all sets, the changes in T2 were significant compared with those at rest (P < 0.01). These results demonstrate that T2, calculated from fast-mfMRI images can be used to detect even a small amount of muscle activity induced by acute exercise, which was impossible to do with cross-sectional areas. Conclusion: Fast-mfMRI, which can also display functional information with detailed forms, enabled non-invasive real-time imaging for identifying and evaluating the degree of deep trunk-muscle activity induced by exercise.

While the competitiveness of small and medium sized cities has become important for balanced development at the national scale, they have experienced continuous decline in population and employment, particularly those in non-capital regions. In addition, some of small and medium sized cities have been classified into shrinking cities that have declined due to their long-term structural reasons. To address these issues, a regional approach, by which a hub city and its surrounding small and medium sized cities can collaborate has been suggested. Given this background, the purpose of this study is to identify and delineate hub cities and their impact areas by using travel data as a functional network index. This study uses a centrality index to identify the hub cities of small and medium sized cities and Markov-chain model and cluster analysis to delineate regional boundaries. The mean first passage time (MFPT) generated from the Markov-chain model can be interpreted as functional distance of each region. The study suggests a methodological approach delineating the boundaries of regions incorporating functional relationships of hub cities and their impact areas, and provides 59 hub cities and their impact areas. The results also provide policy implications for regional spatial planning that addresses appropriate planning boundaries of regions for enhancing the economic competitiveness of small and medium sized cities and ensuring services for shrinking cities.

Purpose: This study examined the dynamic peak plantar pressure under the foot areas in those with a functional leg length inequality. Methods: The dynamic peak plantar pressure under the foot areas in an experimental group with a functional leg length inequality (n=20) and a control group (n=20) was assessed a using the Mat-Scan system (Tekscan, USA). The peak plantar pressure under the hallux, 1st, 2nd, 3-4th and 5th metatarsal head (MTH), mid foot, and heel was measured while the subject was walking on the Mat-Scan system. Results: The experimental group had significantly higher peak plantar pressure under all foot areas when the dynamic peak plantar pressure in the short leg and long leg sides was compared. The control group had a significantly higher peak plantar pressure under the 1st, 2nd, 3-4th, and 5th MTH when the dynamic peak plantar pressure in the short leg and long leg sides were compared. The experimental group showed a significantly larger difference in the dynamic peak plantar pressure under the hallux, 1st, 2nd, 3-4th and 5th MTH, mid foot and heel than the control group. Conclusion: A functional leg length inequality leads to an increase in the weight distribution and dynamic peak plantar pressure in the side of the short leg.

This review provides a comprehensive overview of brain imaging studies of the brain-gut interaction in functional gastrointestinal disorders (FGIDs). Functional neuroimaging studies during gut stimulation have shown enhanced brain responses in regions related to sensory processing of the homeostatic condition of the gut (homeostatic afferent) and responses to salience stimuli (salience network), as well as increased and decreased brain activity in the emotional response areas and reduced activation in areas associated with the top-down modulation of visceral afferent signals. Altered central regulation of the endocrine and autonomic nervous responses, the key mediators of the brain-gut axis, has been demonstrated. Studies using resting-state functional magnetic resonance imaging reported abnormal local and global connectivity in the areas related to pain processing and the default mode network (a physiological baseline of brain activity at rest associated with self-awareness and memory) in FGIDs. Structural imaging with brain morphometry and diffusion imaging demonstrated altered gray- and white-matter structures in areas that also showed changes in functional imaging studies, although this requires replication. Molecular imaging by magnetic resonance spectroscopy and positron emission tomography in FGIDs remains relatively sparse. Progress using analytical methods such as machine learning algorithms may shift neuroimaging studies from brain mapping to predicting clinical outcomes. Because several factors contribute to the pathophysiology of FGIDs and because its population is quite heterogeneous, a new model is needed in future studies to assess the importance of the factors and brain functions that are responsible for an optimal homeostatic state.
