This study has been aimed at figuring out the fact that four kinds of body type grouped according to the tilting of scapular of upper extremity and ilium of low extremity showed the mobility increase for joint parts and the limitation. When we make a thrapy plan which should be comprehensive and general in preventative management and therapy. For the sake of patients who have spinal disabilities including low back pains, it is required for many joints distributing among upper and lower extremity to have hypermobility and hypomobility based on regulation. So, this study was conducted to establish a standard for the effective pattern of hypermobility or hypomobility. I hope that the result of this study can help support the practics of physical therapy as a part of scientic method. Especially I think it will be able to be conductive to those who major in physical therapy on the arthrogenic region.

Biomass is one of the most competitive renewable energy resource and can be used for heating for rural applications. A economic assessment was made of biomass heating, using the tool BIOH2000 from $RETScreen^{\circledR}$ International Clean Energy Decision Support Centre. For a 260kW heating system for 50 farm houses, the assessment showed a very promising results. Internal rate of return was $19.7\%$ and year-to-positive cash flow was 5.1 years. Relative price of biomass over fossil fuel significantly affected the economic feasibility of the project. Heating demand was directly related to annual demand of biomass and economic feasibility. Relative cost of distribution pipe over the total initial costs also affected the economic feasibility of the project. The economic feasibility was expected to be improved by the probable greenhouse emission reduction credit and reduction of initial costs through utilizing existing heating system for peak or back up heating system.

In this study, a new earth retention system has been developed and introduced. This system is a self-supported earth retaining wall without struts. The new earth retention system consists of connected double H-pile and wale. This system provides a larger spacing of support, economical benefit, construction easiness, good performance and safety. This paper explains basic principles and mechanism of self-supported earth retaining wall. In order to investigate applicability and safety of this system, numerical analysis was performed. The finite differential method program, FLAC3D is used. The predicted performances of this system were presented and discussed.

As technology advances rapidly, emergency medical dispatching systems must also advance. Optimal emergency medical dispatching requires the courage to practice medicine at dispatch. Modern emergency medical dispatch provides appropriate resource responses with the use of an (Advanced Medical priority Dispatch System(AMPDS) in U.S.A. The AMPDS is a systematic protocol for all aspects of the dispatch process. Based on the AMPDS chief complaint list, we initiated a basic design on pre-arrival instruction protocol and completed the scripted pre-arrival instruction protocol, using Cardiopulmonary resuscitation(CPR) protocol. Implementation of this study creates computerized emergency medical dispatching system for future enhancements, such as the AMPDS.

In this paper, we studied into a qualitative research to see mathematical understanding of preschool and kindergarten's teachers such as feeling attitude, parents' concern, difficulty of math teaching in kindergarten field, teacher's role, type of feed back, beauty of math, relationship of real life, and self philosophy of math education. We selected 10 teachers whose career was 7~10 years. Because this research way is qualitative, we can new aspect that teacher want to break their ignorance for math. Moreover, they would like to learn about math practicality, application, and beauty from art in professional training. Therefore we assert that fusion math lecture would support in the professional training for teacher, preschool or kindergarten's president training, and remuneration training.

Terrace deposits are often encountered in portal areas and tunnels with low overburden. They are challenging to excavate considering their great mechanical and spatial heterogeneity and a very high stiffness contrast within the ground. Terrace deposits are difficult to characterize, considering that samples for laboratory testing are almost unfeasible to obtain, and laboratory tests may not be representative due to scale effects. This paper presents the approach taken for their characterization during the design stage and their posterior validation performed during construction. Lessons learned from several tunnels excavated on terrace deposits on the Bogota-Villavicencio road (central-east Colombia), suggest that based on numerical simulations, laboratory testing and tunnel system behaviour monitoring, an observational approach allows engineers to optimize the excavation and support methods for the encountered ground conditions, resulting in a more economic and safe construction.

This paper investigates the potential of a hybrid model which combines the least squares support vector machine (LSSVM) and an improved particle swarm optimization (IMPSO) techniques for prediction of concrete compressive strength. A modified PSO algorithm is employed in determining the optimal values of LSSVM parameters to improve the forecasting accuracy. Experimental data on concrete compressive strength in the literature were used to validate and evaluate the performance of the proposed IMPSO-LSSVM model. Further, predictions from five models (the IMPSO-LSSVM, PSO-LSSVM, genetic algorithm (GA) based LSSVM, back propagation (BP) neural network, and a statistical model) were compared with the experimental data. The results show that the proposed IMPSO-LSSVM model is a feasible and efficient tool for predicting the concrete compressive strength with high accuracy.

For Video on Demand(VoD) servers, a design of an efficient scheduler is important to the support a large number of clients having various playback speeds and receiving rates. In this paper, we propose the scheduling algorithm to handle establishing deadlines and selection using the earliest deadline first. To establish deadlines and selections, the period of the receiving rates for each client is located between the over-max receiving rate and the over-playback rate. To avoid video starvation and the buffer overflow of each client, the proposed algorithm guarantees providing the admission control. Because of establishing deadlines and selection, period of each client receiving is between one over max receiving rate and one over play back rate. Using Virtual Buffer in server, scheduling load is reduced. The efficiency of the proposed algorithm is verified using a Petri Net_Based simulation tool, Exspect.

Nowadays, domestic hospital business is under the great threat from the environmental changes caused by the entrance of foreign hospitals and the technical changes related to information systems. In such a situation, to enhance the competitive edge of a hospital, it is needed to set up a competitive strategy and to construct an efficient information systems to back up the competitive strategy. If the hospital information systems(HIS) is consistent with a competitive strategy backing up, the competitive force of a hospital will be enhanced. For this respect, the influence of the competitive strategy and HIS construction environments on the performance of HIS was examined. The results suggested that if a HIS should be newly constructed or should be restructured, it is necessary to select construction environments of HIS such as physical environments, development methods and development tools to support functional strategy effectively based on the competitive strategy adopted by a hospital.

In order to mass-customize clothes, it is essential to take into account individual body shape using computerized 3D body models. This paper describes the development of an interactive body model that can be altered to match individual body perimeter, postures and depth for the purpose of computerized pattern making. Construction of the body model requires the extraction of necessary points, adjustment of coordinate points, linking of points by spline curves, control of section lengths and selectability of various hip types. Front to back depth of the model is adjusted by scaling ratio. We had a great result for controlling perimeter, posture and depth of body shapes. The results support the adaptability and potential usefulness of the posture and depth adjustable body model.
