Falls are the most serious health problems in elderly population. They are a major cause of premature death, physical injury, immobility, psychosocial dysfunction, and nursing home placement. To reduce the alarming rate of falls and related excessive mortality and morbidity, efforts must be made to detect persons at risk of falling and to prevent or reduce the frequency of falls. To facilitate such approaches, it is essential to find the cause of falling (and under what conditions) of the elderly and the factors that are associated with risk of falling. This study was aimed at designing interventions that minimize risk of falling by ameliorating contributing factors while maintaining or improving patient's mobility.

This paper analyzes: (1) the effects of the population growth in the regions in which the campuses are located (2) the economic effects (3) the social and cultural effects 94) the linkage effects between university and regional community. It is found that the campuses have various effects on the regional community through the human capitals, economic and cultural factors, and educational program. In particular local campuses have substantial impacts on regional economy. Two local campuses have been found to have more regional income effects than manufacturing and service industries do. Thus, it is necessary that the growth of linkage mechanism with universities and induced consumption expenditure by universities should be constructed in the region having local campuses. In order to increase these effects on regional development, much attention should be given to the regional development aspect from university authorities, students, professors, and residents. Also from the national policy point associated with material-moving policy and capital mobility policy in relation to the universities should be estabilished.

Starch gel electrophoresis was used to estimate the degree of genic variation and genetic relatedness among twelve populations of the Cat-Sanke(Elaphe diene) in Korea. Out of the 17 loci examined 9 loci (Mdh-2, Ldh-1, Ldh-2, Idh-1, Idh-2, Adh, Aco-3, ep, Got-1) were monomorphic with identical mobility in all populations, 4 loci (Pgm, Mpi, Pept-1, Got-2) were nearly identical with minor allele frequency differences, and 4 loci (Mdh-1, Fgi, Est-2, 6psd) showed moderate variation. Levels of genic variation were similar to those found for other reptilian species. The mean genetic similarity value(S) among twelve populations is 0.966. Chechu population was slightly remote genetically from the mainland populations.

Focusing on the hermeneutic instability of a key word of Paradise Lost, "wander," this study attempts to situate John Milton's early modern epic in the longue $dur{\acute{e}}e$ historical transition from seignorial to capitalist mode of production, especially the displacement and reorganization of producer population, a corollary of early phase of modernization. The historic experience of vagrancy and its normalization, and the concomitant shift of the primary human sociability from given to voluntary bonds, I suggest, shape and inform Milton's early modern rewriting of the Biblical story of the fall and his revising of the heroic epic romance into a plebeian romance of a wandering, companionate couple. While building on the critical consensus on this poem's deliberate distancing from the tradition of classical epic and chivalric romance, this essay argues that Milton re-appropriates and re-channels the aspirational aspect of chivalric wandering, or mobility, for his plebeian heroes, a companionate conjugal couple. The hermeneutic instability of the word wander, this essay suggests, captures the duality of the historic experience of vagrancy, both the tragic experience of displacement and the liberational and uplifting dimension of that experience.

As environmental pollution has become severe due to the rapid increase in pollutant generation in the air, measurement, collection, and analysis of atmospheric environment information plays an important role. However, it is difficult to measure the high-resolution and real-time atmospheric environment of the cities and tourist spots with high population mobility only by measuring equipment of stationary measuring stations. Therefore, this paper proposes a portable atmospheric environment measurement system for real-time measurement and monitoring of atmospheric environment information. The proposed system is a portable client with a low-power wireless communication method. It is possible to reliably transmit and receive the measured data through a multi-threaded server to monitor the trend of pollutants in the air in real-time.

In 2005, the selection of 10 innovation cities was completed, and since 2013, public institutions began relocating to innovation cities. As a policy aimed at promoting balanced regional development, there were significant expectations from the regions. However, although the population moving to innovation cities has increased, it remains to be seen how much inflow is from the capital region and what spatial characteristics exist nationwide. Therefore, this study aims to analyze whether the innovation cities are fulfilling their roles by examining the patterns of inflow from the capital region and the spatial characteristics, and to reassess the policy direction for future innovation cities. We utilized the Microdata Integrated Service (MDIS) provided by Statistics Korea from 2013 to 2021. For the data collection reasons, we focused on analyzing the three cities. The results showed that in the initial stages of innovation city development, there was a significant influx of population from the capital region, leading to some effects on population dispersion and balanced regional development. However, over time, a phenomenon emerged where more people started to move back to the capital region, indicating a problematic trend. Furthermore, the Gyeongbuk Innovation City and Gwangju-Jeonnam Innovation City showed similarities in terms of reasons for migration, age of householder, and number of household members. However, the Gyeongnam Innovation City exhibited distinct characteristics compared to the other two cities. While the reasons for this phenomenon may be diverse, the current situation suggests that the goal of achieving "balanced national development" has reached its limits. Therefore, urgent measures need to be taken for improvement that take regional characteristics into account. Furthermore, in designing the second phase of the public institution relocation plan is required to avoid repeating the same issues and ensure a more thoughtful approach.

New developments in IT already impact wide segments of a young and mobile population. It is evident that applications of information technology can be of equal benefit to the aged and the disabled. `Eye-Gaze'(EGI) technology was designed for people with paralysis in the upper body. There is a compeling need for a dedicated Korean Language interface for this system. The purpose of this study is to research 'Barrier Free' software using a control group of the mobility impaired to assess the Eye-Gaze Interface in the context of more conventional input methods. TheEGI of this study uses Quick Glance System of Eye Tech Digital Systems. The study will be evaluated on criteria based upon the needs of those with specific disabilities and mobility problems associated with aging. We also intend to explore applications of the Eye-Gaze Interface for English and Japanese devises, based upon our study using the Hangul phonology.

Background: Neurodynamic mobilization is divided into slider mobilization and tensioner mobilization. However, movement direction in neurodynamic mobilization has been overlooked in neurodynamic exercise program. Objective: To examine the effect of movement direction in neurodynamic mobilization on upper limb mobility and pain. Design: Quasi-experimental study Methods: Twenty-two adults positive for neurodynamic test for the median nerve were recruited for participation in this study. Twenty-two subjects were allocated to the applied neurodynamic mobilization at limited side group (ANTLS, n=7), the applied neurodynamic mobilization at contralateral limited side group (ANTCLS, n=7), and the applied neurodynamic mobilization at bilateral side group (ANTBS, n=8). Before the intervention upper limb limited was measured neurodynamic test for the median nerve, pain was measured using visual analogue scale (VAS), movement direction in neurodynamic mobilization was applied to each group, and then re-measured using neurodynamic test for the median nerve and VAS. Differences the Intra-groups before and between the intergroups after intervention were analyzed. Results: In the ANTLS and ANTBS groups, a statistically significant increase in ROM and decrease in VAS score in the population before and after intervention were indicated. Statistically significant differences in VAS and ROM from before to after intervention were found among the ANTLS, ANTCLS, and ANTBS groups. Conclusions: The results of the present study indicate that movement direction in neurodynamic mobilization must be considered within the limits of its selected range of the neurodynamic exercise program.

In this paper, the design requirements was produced by analyzing domestic and foreign regulations of the vertical takeoff and landing site required to operate the urban air mobility (UAM) system in Korea and the size of the take-off and landing pads were defined, and the configuration of vertiport was proposed. First, for the metropolitan area with high population density, pilot locations of the vertical take-off and landing site were selected based on the demonstration routes suggested by the Ministry of Land, Infrastructure and Transport and analyzed the characteristics of each location and determined the number of possible installations of vertiport by measuring each site. After that, variables necessary for the operation of the vertical takeoff and landing area were set, and the hourly, daily, monthly aircraft operating cycle, the number of acceptable people, and efficiency were calculated according to the number of simultaneous operation and the number of stand. Finally, using CATIA, the configurations of the virtual vertiport was created by applying the design requirements.

In this paper, locations of vertiports were selected and evaluated to operate urban air mobility (UAM) in the Seoul metropolitan area. Demand data were analyzed using the data from the survey of commuting population and were marked on a map using MATLAB. To cluster the data, the K-means algorithm function built in MATLAB was used to identify the center of the cluster to as the location of vertiports, and using the silhouette technique, the accuracy and reliability of the clustering were evaluated. The locations of the selected vertiports were also identified using satellite maps to ensure that the locations of the selected vertiports were suitable for the actual vertiport location, and, if the location was not appropriate, final vertiports were selected through the repositioning process.
