University dorm basically provides basic housing functions to students, however, it is very important in a sense that it provides students with various functions such as information exchange, cultural experience and learning environments as well. Additionally, continuous effort to improve users' satisfaction and living environments are needed due to the fact that physical environments of dorm facilities have higher impact on students. However, Many students are not satisfied with the physical environment of university dorms and also there is lack of systematic information whereas various functions are required by students. Therefore, the main objective of this research is to suggest the direction of FM services in order for improving students' satisfaction on the university dorm facilities in Korea. Precedent studies regarding the satisfaction or performance evaluation of dorm facilities have been extensively analyzed to extract the dissatisfaction factors that scored below the middle 50%. Secondly, for satisfaction improvement, Korean Standard for Facility Management(KS_FM) have been matched with those extracted dissatisfaction factors to suggest the direction of FM services by rules and regulations review and best practice studies. This research will be useful for university dorm facility managers in planning strategic FM and providing effective FM services to students.

The rational finite element method is different from the standard finite element method, which is constructed using basic solutions of the governing differential equations as interpolation functions in the elements. Therefore, it is superior to the isoparametric approach because of its obvious physical meaning and accuracy; it has successfully been applied to the isotropic elasticity problem. In this paper, the formulation of rational finite elements for plane orthotropic elasticity problems is deduced. This method is formulated directly in the physical domain with full consideration of the requirements of the patch test. Based on the number of element nodes and the interpolation functions, different approaches are applied with complete polynomial interpolation functions. Then, two special stiffness matrixes of elements with four and five nodes are deduced as a representative application. In addition, some typical numerical examples are considered to evaluate the performance of the elements. The numerical results demonstrate that the present method has a high level of accuracy and is an effective technique for solving plane orthotropic elasticity problems.

Image fusion is a technical method to integrate the spatial details of the high-resolution panchromatic (HRP) image and the spectral information of low-resolution multispectral (LRM) images to produce high-resolution multispectral images. The most important point in image fusion is enhancing the spatial details of the HRP image and simultaneously maintaining the spectral information of the LRM images. This implies that the physical characteristics of a satellite sensor should be considered in the fusion process. Also, to fuse massive satellite images, the fusion method should have low computation costs. In this paper, we propose a fast and efficient satellite image fusion method. The proposed method uses the spectral response functions of a satellite sensor; thus, it rationally reflects the physical characteristics of the satellite sensor to the fused image. As a result, the proposed method provides high-quality fused images in terms of spectral and spatial evaluations. The experimental results of IKONOS images indicate that the proposed method outperforms the intensity-hue-saturation and wavelet-based methods.

This current research investigated whether job stress mediates the relationship between physical environment and safety behavior of members in organization. Furthermore, we hypothesized that safety climate functions as moderator between physical environment-job stress link. In order to examine the hypotheses, 870 employees in various fields of companies were sampled. Using structural equation modeling(SEM), we conducted moderated mediation model analysis which cab elaborately test the significance of our hypotheses. The results showed that job stress mediated the link between physical environment and safety behavior of members. Moreover, the relationship between physical environment and job stress was moderated by safety climate. The implications and limitations of our study and suggestions for future research were discussed.

The proportion of the aged people in Korea has increased rapidly by more than 7% in 2000. A survey says that the changing rate from the aging society to the aged is the highest among the OECD countries. The prevalence rate of the aged population is on the increase. Chronic diseases such as arthritis and strokes limits their body's functions and activities of daily living. It is necessary that functional training. ADL training and continuous treatment be provided by Physical or Occupational Therapists. Discontinuance of treatment can cause the aged people to be in a bed state. The aged people need a variety of home care services at their convenience. Occupational and Physical therapist should play a major role in providing the rehabilitation-base home care services. Further they are expected to contribute to the extension of health care services such as home care and nursing home programs.

[ ($1{\to}3$) ], ($1{\to}4$)-${\beta}$-D-glucans(${\beta}-glucans$) are a major component of the cell walls of grasses as a component of the cereal endosperm and aleurone cell walls. Although ${\beta}-glucans$ exist in all cereals, their concentration is highest in oats and barley. Genetic and environmental differences are found in total ${\beta}-glucan$ content. Both oats and barley ${\beta}-glucans$ have cholesterol-lowering effects. This suggests possible use as food additives. Structural characterization of ${\beta}-glucan$ is important because structure can influence physical and physiological properties. In this review, ${\beta}-glucans$ of barley and oats are discussed in details including structure, chemical and physical properties, and nutritional implications. The use of barley and oat products as well as ${\beta}-glucan$ as a food additive continues to increase. This can provide an additional market for barley and oats, thus increasing the value of the crops.

Because of a recent trend of the open and globalized world economy, international trade is getting bigger and there is a trade competition among many countries, resulting in competition between harbor industries. Therefore, as hub-port development of China, Japan and Taiwan is more actively progressing than any other times, Korea should prepare a powerful management system to take the initiative over them. Above all, a new recognition of the governmental officers in charge of political management about hub-port industry and early development of the northeast hub-port are needed. To maximize its distinctiveness from competitive ports, port sale should be actively managed. As well, as port functions are diverse, accompanied site development should be prepared. In conclusion, in order to improve functions of a port and develop the port as a general complex of physical distribution, the government should encourage the accompanied site development and support preparation of a customs-free area and a general system of physical distribution.

The purpose of this study was an determine whether elastic band on treadmill training might effect the chest expansion and pulmonary function of the 20's men. 40 subjects with experimental group(male: 20) and control group(male: 20) was participated in experiment. During four weeks, each group participated thirty minutes for three times per week. Subjects were assessed using pre-value and post-value measurement chest length(chest length for resting, chest expansion) and pulmonary function(forced vital capacity, forced expiratory volume at one second, FEV1/FVC, peak expiratory flow, vital capacity, tidal volume, expiratory reserve volume, inspiratory reserve volume) by the CardioTouch 3000S(BIONET, USA). These findings suggest that experimental group can be used to improve chest expansion, pulmonary function than control group. In comparison of both groups, post-test was more improved in experimental group. In conclusion, experimental group helped improving function of pulmonary volume and respiratory muscle, and thus it indicates that the functions will be more improved through the continued respiratory exercise program.

The bubble size distribution is critical information to understand sound propagation and ambient noise in the ocean. To estimate the bubble size distribution in a bubbly water, the sound attenuation has been only in the conventional acoustic bubble sizing method without considering the sound speed variation. However, the effect of the sound speed variation in bubbly water cannot be neglected because of its compressibility variation. The sound attenuation is also affected by the sound speed variation. In this paper, a coherent acoustic bubble sizing inverse technique is introduced as a new bubble sizing technique with considering sound speed variation as well as the sound attenuation. This coherent sizing method is theoretically verified with the bubble distribution functions of single-size, Gaussian, and power-law functions. Its numerical test results with the coherent acoustic bubble sizing method show good agreement with the given bubble distributions.
