Purpose: This study was carried out to substantiate the application process of activity-based costing on the current cost of hospital home care (HHC) service. The study materials were documents, 120 client charts, health insurance demand bills, salary of 215 HHC nurses, operating expense, 6 HHC agencies, and 31 HHC nurses. Method: The research was carried out by analyzing the HHC activities and then collecting labor and operating expenses. For resource drivers, HHC activity performance time and workload were studied. For activity drivers, the number of HHC activity performances and the activity number of visits were studied. Result: The HHC activities were classified into 70 activities. In resource, the labor cost was 245￦per minute, operating cost was 9,570￦ per visit and traffic expense was an average of 12,750￦. In resource drivers, education and training had the longest time of 67 minutes. Average length of performance for activities was 13.7 minutes. The workload was applied as a relative value. The average cost of HHC was 62,741￦ and the cost ranged from 55,560￦ to 74,016￦. Conclusion: The fixed base rate for a visit in the current HHC medical fee should be increased. Exclusion from the current fee structure or flexible operation of traveling expenses should be reviewed.

This study aimed to compare the bioactive compounds in Centella asiatica (C. asiatica) cultivated in a smart farm and a field and their effects on human keratinocyte cells. C. asiatica was collected in Jeju-do, Korea, and cultured in a smart farm and a field. The main bioactive compounds in the two differentially cultured C. asiatica were identified, and their activation in keratinocytes were assessed. Amplification and sequencing of the internal transcribed spacer (ITS) DNA in the nucleus and psbA-H DNA in the chloroplast were performed for species analysis. A comparison of DNA of plants reported in the NCBI GenBank was performed. The ITS DNA and psbA-H DNA sequences of C. asiatica cultivated in a smart farm and a field were consistent with No. MH768338.1 and No. JQ425422.1, respectively. Analysis of the triterpenes was performed using high performance liquid chromatography (HPLC) and as a result, C. asiatica cultured in a smart farm had more triterpenes than those cultured in a field. The effects of C. asiatica grown in a smart farm on cell proliferation and scratch recovery in HaCaT cells were greater than those grown in a field. These results suggest that C. asiatica cultivated in a smart farm can be effectively utilized as a health functional food.

Purpose: The purpose of this study was to propose optimal hospitalization fees for nurse staffing levels and to improve the current nursing fee policy. Methods: A break-even analysis was used to evaluate the impact of a nursing fee policy on hospital's financial performance. Variables considered included the number of beds, bed occupancy rate, annual total patient days, hospitalization fees for nurse staffing levels, the initial annual nurses' salary, and the ratio of overhead costs to nursing labor costs. Data were collected as secondary data from annual reports of the Hospital Nursing Association and national health insurance. Results: The hospitalization fees according to nurse staffing levels in general hospitals are required to sustain or decrease in grades 1, 2, 3, 4, and 7, and increase in grades 5 and 6. It is suggested that the range between grade 2 and 3 be sustained at the current level, the range between grade 4 and 5 be widen or merged into one, and the range between grade 6 and 7 be divided into several grades. Conclusion: Readjusting hospitalization fees for nurse staffing level will improve nurse-patient ratio and enhance the quality of nursing care in hospitals. Follow-up studies including tertiary hospitals and small hospitals are recommended.

Objectives: Because recently hospital had to faced with financial hardship, we have to have more effective hospital management. The purpose of this study was to reduce loss costs of the hospital through the systematic management of medical supplies and increase operational efficiency. Methods: The team was composed of outpatient nursing staff, medical record administrator, nurses in medical insurance, medical computer center, dermatologists for this study. We surveyed for 114 people including outpatient nursing staff, nurse aids, medical assistant, physician assistant. Pre-survey period was 2013.03.11 ~ 03.30(2 weeks), and post-survey period was 2013.09.03 ~ 09.17(2 weeks). Result: We improved this way through the computational improvement, conservation campaigns, inventory management, staff training, replaced by low-cost medical supplies. The finding of this study were as follows: Comparing before and after the activity of outpatient nursing staff's degree of knowledge, performance, economic consciousness, the degree of knowledge, performance was increased, but there was no significant change in economic consciousness. Performance of Married person is higher than the unmarried, In addition, the high-position people were more the degree of knowleage, economic consciousness. After activity, correlation of goods and treatment, examinations is increasing, but statistically there was no mean. Conclusion: This study revealed that knowledge in a short period of activity, but also can improve, perform the same change in behavior is not easy. This one shows the intensive training required to sustained and systematic behavioral changes, such as changes in behavior, perform rituals to help the economy. Expensive medical supplies to replace a similar effect as the cost of materials just to have a lot of cost savings. Therefore, more medical supplies change is necessary to develop alternative treatment and cost cutting.

This study uses Korea's equity fund-related data ranging from Jan. 2002 to Apr. 2010 to analyze the existence of cross-subsidization among funds managed by the same management company. The findings are as follows: i) a transfer of performance outcome is confirmed to move from low-fee funds to high-fee funds, meaning that management companies tend to maximize their own interest than investors' return. And such a tendency has been strengthened since 2008. ii) young funds overperform old funds, iii) funds with high returns in the previous quarter perform better than funds with low return in the same period. These results suggest that in order to protect investors, it is necessary to conduct close monitoring on transactions that might undermine the benefits of investors and comprehensive evaluation on the capability of management companies.

Cloud Computing allows application providers seamlessly scaling their services and enables users scaling their usage according to their needs. In this paper, using queuing game model, we present service scheduling schemes which are used in software as a service (SaaS). The object is maximizing the Cloud Computing platform's (CCP's) payoff via controlling the service requests whether to join or balk, and controlling the value of CCP's admission fee. Firstly, we treat the CCP as one virtual machine (VM) and analyze the optimal queue length with a fixed admission fee distribution. If the position number of a new service request is bigger than the optimal queue length, it balks. Otherwise, it joins in. Under this scheme, the CCP's payoff can be maximized. Secondly, we extend this achievement to the multiple VMs situation. A big difference between single VM and multiple VMs is that the latter one needs to decide which VM the service requests turn to for service. We use a corresponding algorithm solve it. Simulation results demonstrate the good performance of our schemes.

Turn-key and CMF(CM for Fee) have been selected as procurement paths of large public projects in Korea. However, recently, researches and discussions on CMR(CM at Risk) have been popular as the Korean government seeks for alternative procurement paths to enhance the performance. In the CMR projects, the part who is responsible for construction management should predict and control the potential risks for guaranteeing benefits. In this research, CMR projects in which a general contractor plays the role as CMr is mainly analyzed. We give attentions to risk management during construction process given that subcontractors, main parts in this phase, work in various ways and thus more chances for faults exist. In this case, CMr manages risks to control the procedure of project. So, potential risk factors can constitute the database, and that database can be matched to following activity. And construction manager can forecast measures of risk using the result of matching. This chain of activities increase efficiency in roles of CMr on CMR(CM at Risk). Furthermore this study will propose one of the solution of Construction Management Module.
