Purpose : This study compared the cost-effectiveness ratio of physical therapy in health centers and home physical therapy, two physical therapy methods for home-bound stroke patients, and clarified the economic validity regarding the effect of home physical therapy. Methods : To measure and compare the cost and effectiveness of the two physical therapy methods for stroke patients, subjects were recruited based on in-hospital and home physical therapy. Among the entire data collected, 82 and 90 participants were selected for in-hospital and home physical therapy, respectively. To measure costs, regarding both in-hospital and home physical therapy, direct cost and indirect cost for patients, family, medical institutes, and the government were measured. In addition, activities of daily living were measured in both methods to measure their effectiveness. Through collected data, the cost-effectiveness and incremental cost-effectiveness ratios were analyzed. Results : Based on the analysis of cost-effectiveness, home physical therapy showed lower cost-effectiveness than in-hospital physical therapy. Furthermore, the incremental cost-effectiveness ratio also showed a difference, which implied home physical therapy could have high effectiveness compared to cost. Conclusion : Based on these results, home physical therapy could be considered as an alternativeto other methods of physical therapy, for home-bound stroke patients. In addition, the result of thisstudy contribute by providing evidence that home physical therapy offers economic benefits and canbe more effective in treating home-bound patients when policy decisions are made to establish a home physical therapy system.

Purpose: The aim of this study was to demonstrate that non-participation of physical therapists on the political decision-making committee results in invasion of their interests. Methods: To demonstrate the effects, we analyzed the change of medical insurance score decided by the Health Insurance Policy Deliberation Committee between 2001 and 2012 years, focusing on medical examination as the interest of the participation group and physical therapy cost as interest of the non-participation group. Results: Total medical insurance cost increased by 23.72%, on average. Medical examination cost increased by 23.90% and 37.66% in medical examination for new and established patients, respectively. However, physical therapy cost was reduced by 5.01%. The medical examination cost for physical therapy without medical checkup increased by 2.62%. Conclusion: This study shows that the physical therapy cost, related on the interest of the non-participative group in the Health Insurance Policy Deliberation Committee, rather decreased while the total medical insurance cost increased.These findings demonstrate the invasion of the non-participative group on the Health Insurance Policy Deliberation Committee. Thus, aggressive participation in political decision-making committee is necessary in order to protect and increase rights and interests of Korean physical therapists.

When physical distribution cost can be correctly measured, its management can also be efficient. Thus the primary objective of the study is to develop systems for measuring correctly physical distribution cost. The systems have two aspects : the One is the consumption of the resourses(materials, labor service, the other services), the other is the creation of physical distribution services(transportation, storage, cargo, packing, distribution conversion, management). By measuring the cost through the systems, the commoditization of the physical distribution services is possible and measurement of the cost and revenue can also be reasonable ,which makes its management efficient.

This paper aims to determining the optimal capacity of Pusan port in view point of Container Physical Distribution cost. It has been established a coast model of the container physical distribution system in Pusan port is composed of 4 sub-systems and in-land transport system. Cargo handling system, transfer & storage system and in-land transport system, and analyzed the cost model of the system. From this analysis, we found that the system had 7 routes including in-land transport by rail or road and coastal transport by feeder ship between Pusan port and cargo owner's door. Though railway transport cost was relatively cheap, but, it was limited to choose railway transport routes due to the introducing of transport cargo allocation practice caused by shortage of railway transport capacity. The physical distribution ost for total import & export container through Pusan port was composed of 4.47% in port entring cost, 12.98% in cargo handling cost, 7.44% in transfer & storage cost and 75.11% in in-land transport cost. Investigation in case of BCTOC verified the results as follows. 1) The optimal level of one time cargo handling was verified 236VAN (377TEU) and annual optimal handling capacity was calculated in 516, 840VAN(826, 944TEU) where berth occupancy is $\rho$=0.6 when regardless of port congestion cost, 2) The optimal level of one time cargo handling was verified 252VAN (403TEU) and annual optimal handling capacity was calculated in 502, 110VAN (803, 376TEU) where berth occupancy is $\rho$=0.58 when considering of port congestion cost.

The purposes of this study were to investigate children's prosocial behavior by age and sex and to examine the relationship between children's prosocial moral reasoning and prosocial behavior by costs and types of tasks. The subjects were 300 3th-and 6th-graders enrolled in elementary schools in Seoul. The revised form of Prosocial Moral Dilemmas including costs and types of tasks was used. The tasks of prosocial behaviors included time-cost tasks, money-cost tasks and physical strength-cost tasks. For data analysis, the paired t-test, two-way ANOVA, and Pearson's Correlations were used. Major findings were as follows; (1)There was age difference in children's prosocial behavior. 6th-graders performed at a higher level than 3th-graders. Sex differences weren't significant. In low- and high-cost tasks and in time-, money-, and physical strength-cost tasks, there were (2) Scores on high-cost behavior tasks were higher than on low-cost tasks. (3) Children's prosocial moral reasoning was positively related to prosocial behavior; in low- and high-cost tasks, and in time-, money-, and physical strength-cost tasks.

The purpose of this study was to explore whether there is a point within the range of physical impairment after which the cost of home care exceeds the cost of nursing home care among the elderly who require long-term care. The provision of long-term care for the elderly is a major health policy issue, in part due to the aging of the American population and dramatic increase in health care costs. The framework for this study was guided by Pollak's(1973)model of costs of alternative care settings for the elderly. This study used a retrospective, descriptive correlational design. Physical impairment was measured by the modified Index of Activities of Daily Living(Katz et al. 1963). Cost of care was measured by the average cost per patient per day. The sample for this study included 67 patients receiving long-term care at home from the Long-term Home Health Care Programs (LTHHCPs) and 67 patients receiving long-term care in nursing homes. Data were collected on patient characteristics. including activities of daily living and cognitive impairment. and on the number of physician visits. emergency room visits. and hospitalization from the patient records. For each patient. Medicaid cost data for home care services/or nursing home services were collected from the financial department of each home care agency or nursing home. The living costs and informal care costs were estimated for home care patients. The results indicated that the home care sample and the nursing home sample were similar in terms of gender. ethnic background. and marital status. The elderly patients in the home care sample were: however. younger and less physically impaired than those in the nursing home sample. The hypotheses of this study were supported: For elderly persons with physical impairment scores below 12(possible range of 0 to 14), cost of care was lower in home care than in the nursing home care setting. However, for elderly persons with physical impairment scores above 12. the cost of care was higher in home care than in the nursing home care setting. Thus. in this sample for elderly patients with extreme physical impairment, the cost of home care exceeded the cost of nursing home care.

As the utilization of microservice architectural style in diverse applications are increasing, the microservice deployment cost became a concern for many companies. We propose an approach to reduce the deployment cost by generating an algorithm which minimizes the cost of basic operation of a physical machine and the cost of resources assigned to a physical machine. This algorithm will produce optimal resource allocation and deployment location based on genetic algorithm process.

Purpose: This study attempts to find the effects of water-based exercise performed on stroke patients in their physiological cost index and static and dynamic balance. Methods: The subjects were 30 stroke patients, who were randomly divided a water-based exercise group and a land-based exercise group, each with 15 patients. Both exercises ware performed 3 day per week, for 40 minutes a day, for a period of eight weeks. Results: The Water-based exercise group showed a decreased physiological cost index compared to the land-based exercise group, with the physiological cost index of the water-based exercise group decreasing, while the land-based exercise group, showing a significant decrease. Water-based exercise increased static and dynamic balance capacity better than land-based group, showing a significant difference and better efficiency of water-based exercise when compared to land-based exercise. Conclusion: From the result of the study, we found that water-based exercise is more effective in improving PCI and static and dynamic balance capacity. Through this study, training in water-based stroke patients could use cardiovascular endurance and buoyancy and the vortex, as an effective treatment that can enhance the growth and voluntary participation in the range of the patient's own movement the thought is, in consideration of the changes in the physiological cost index due to the difference in the ground and water, and should establish a training program that matches the purpose.

PURPOSE: This study aimed to determine the effect of active trunk training in the sitting position on balance and energy consumption in early stroke patients. METHODS: The subjects of this study were twenty four early stroke patients were recruited and randomly divided into two groups; experimental group (n=12) and control group (n=12). The subjects in the experimental group participated in active trunk training (20 min) and conventional physical therapy (20 min) five times a week for four weeks. The control group conducted general balance exercise (20 min) and conventional physical therapy (20 min) five times a week for four weeks. The outcomes were assessed using the Berg balance scale, Timed up and go test and energy cost and physiological cost index. RESULTS: Both groups showed a significant increase in their Berg balance scale and significant decrease in their Timed up and go test score, and energy cost and physiological cost index (p<.05). Compared to the control group, the experimental group experienced a greater increase in the Berg balance scale (p<.05) and a larger decrease in the timed up and go test score, and energy cost and physiological cost index (p<.05). CONCLUSION: We suggest that active trunk training in the sitting position may be effective in improving balance and energy consumption in early stroke patients. Thus, active trunk training is important for such patients. Further studies are needed to better understand the effectiveness of trunk training in early stroke patients.

In this study, as part of a research on the development of economical high-performance concrete with high strength and high quality, the physical properties of high-performance concrete were analyzed by substituting a certain amount of low-cost domestic silica fume exempted from the re-importation type distribution structure of the domestic production and the existing high-priced silica fume distribution structure. Performing tests to identify the physical properties of the fresh and hardened concrete and durability analogy of the concrete which use low-cost domestic silica fume and imported silica fume, the chloride ion penetration resistance test result showed that the strength difference between the low-cost silica fume and the imported silica fume is not big but the strength of the low-cost silica fume was measured higher than the imported silica fume. The chloride ion penetration resistance of all variables was measured as "very low". Since the low-cost domestic silica fume can be used as a high-performance admixture of concrete, the results suggest that it is possible to produce a more economical high-performance concrete.
