The landscape architecture construction cost estimation includes the repeated calculation and updating. Thus, it is time-consuming, and one of the jobs which needs to be automated first. In Korea, the IBM compatible personal computer(PC) is the most widely used one in the landscape architecture firms. However, the software for landscape architecture construction cost estimation is not being used in the PC environment. Therefore, the purpose of this study is to develop the software which can be used to automate the calculation for the landscape architecture construction cost estimation, and runs in the IBM compatible personal computers(PC). The clipper '88 summer is one of the DBMS software packages, and it has many commands and functions and functions which reduces program lines and makes the programing efficient, especially in the programing work whose total source code lines do not exceed over 10,000 lines. So, it was used in this study. The software developed in the this study was tested using the real data, and it was found that it can be efficiently used in the following jobs. They are: (1) to calculate exactly and rapidly. (2) to use resources repeatedly. (3) to print out the results. (4) to store data files for the future use. The software, as discussed in this paper, reduces the time and efforts to be spent in the calculation for the landscape architecture construction cost estimation compared with the traditional approach using the pocket calculator.

The purpose of this paper is to investigate the structure of cost-sharing for oriental medical services in the national health insurance. Out-of-pocket payment in ambulatory oriental medical care is a co-payment of KRW3,000 up to total expenses of KRW15,000, and co-insurance rate of 30% thereafetr. The empirical analysis based on medial claims data shows that the frequency of medical claims for outpatient care are mostly concentrated just below a total expenses of KRW15,000, and it decreases beyond a total expense of KRW15,000, while it rebounds between KRW17,000${\sim}$20,000. This means the current co-payment(KRW3,000) in oriental medical services should be applied up to a total payment of KRW17,000${\sim}$20,000, or the level of co-payment should be adjusted upward to KRW45,000 in order to be consistent in cost-sharing, between co-payment and co-insurance.

The contents of prescription service were comparatively analysed between health centers(HC) and private clinics(PC). Medical chart review was done for 330 otu-patients diagnosed with upper respiratory tract infection(UR) of 120 adults and 90 children, and gastritis or duodenitis of 120 adults. Emphasis on comparison was the prime cost of medication which used in prescription service. The results were as follows; 1. The prime costs fro the medication per visit of HC group were significantly higher than PC group in all three diseases, and the out of pocket payments of patients per visit were significantly lower in the HC group than PC group. 2. The reason for high prime costs of medication per visit of HC in adult case of URI were due to the idverse use of medication and long prescription period per visit. And high medication costs in children cases of URI in HC group were due to the longer prescription day. In cases of gastritis, the prime cost of medication was also higher because of longer prescription period and the higher prime cost of medication. The proportions of medications for injection in the HC and PC groups showed similar features. 3. In depth analysis of the prescription services showed the differences of the contents of medication. In adults cases of URI, the averaged cost of oral medication was significantly lower in HC group, but that of medication for injection was higher in HC group. In children cases of URI, the averaged cost of oral medication and medication for injection was lower in HC group than in PC group. But in the cases of gastritis it was was higher in HC group than in PC group. The prescription periods were longer in HC group than in PC group in all three diseases. As a conclusion prime medication cost and quality of prescription services of HC group were higher than PC group. In terms of health care the cost containment and quality assurance in physician visit for common disease, public sector utilization is good option for those perspectives. But it should not be generalized unless future study about structure and outcome research for quality assurance.

In order to suggest the proper optimal conditions of the CNC milling machining for the Thin-wall surface, some experiments were carried out. The process was applied in the aerospace industry for the machining of light alloys, notably aluminium. In recent year, however, the mold and die industry has begun to use the technology for the production of components, including those manufactured from hardened tool steels. And the end mill is an important tool in the milling process. A typical example for the end mill is the milling of pocket and slot in which a lot of material is removed from the workpiece. Therefore the proper selection of cutting parameter for end milling is one of the important factors affecting the cutting cost. In this paper, we choose the optimal parameters(cutting forces) to cut thin-walled Al part by experiment.

Objectives: The aim of this study was to explore the prevalence of type 1 diabetes in patients with schizophrenia and their total medical costs and risk of hospitalization. Methods: This study used Health Insurance Review and Assessment Service data in Korea. To examine total medical costs and risk of hospitalization, we selected 1,510 subjects with schizophrenia (half with and half without type 1 diabetes) that were 1:1 matched via propensity score matching. In health care system perspective, total medical costs included out-of-pocket and insurer's costs. Logistic regression models were used to examine the risk of hospitalization. Results: The prevalence of type 1 diabetes in patients with schizophrenia was 3.87 per 1,000 person year. Among patients with schizophrenia, the amount of total average medical costs and hospitalization costs in patients with type 1 diabetes was 1.49 and 1.59 times higher than those in patients without it, respectively. The odds of hospitalization were higher among patients with type 1 diabetes compared with those without it (odds ratio, OR=1.97 ; 95% CI 1.60-2.43). Conclusion: This study showed that medical costs and risk of hospitalization were higher in schizophrenia patients with type 1 diabetes. Therefore, these individuals may require specific care programs.

Due to the existence of asymmetry of information between doctor and patient, it has been believed that doctor might affect patient's decision making process of purchasing medical care. Based on this notion, doctor's reimbursement method has been suggested as an effective policy device of improving efficiency of patient's medical care use by way of its affecting doctor's practice pattern. By using the Community Tracking Study (CTS) household and physician data set, which includes not only various information on patient's medical care use, but doctor's practice arrangements and sources of practice revenue, this paper investigates the effect of community doctor's characteristics of reimbursement method on community patient's medical care use under the control of patient's socio-demographic characteristics and community doctor's practice type. In the process of estimating econometric model, the endogeneity problem of individual health insurance purchase was corrected by using 2818. And due to the existence of sample selection problem, Heckman's two-step estimation method was used for strengthen the robustness of estimation which was adversely affected by sample selection problem The empirical results show that as the average value of community doctor's portion of practice revenue determined by prospective method out of total revenue increases, the community patient's total out-of-pocket medical cost decreases. This results suggest, as doctor's practice revenues are mainly determined by prospective method, such as capitation, doctors would be more conscious about practice cost, which might affect doctor's practice pattern and by which his/her patient's use of medical care would decrease.

With the introduction of national health insurance, the burden of health care costs decreased and choices of medical services widened. However, because of the rapid expansion of non-covered medical services by health insurance, financial security for health care expenditure is still low. This gives patients barriers to choose medical services especially for non-covered medical services, and it becomes narrower. Compared to Korea, Japan has high financial protection in health care utilization, but there exists a limitation using covered and non-covered medical services both together. This is called a prohibition of mixed treatment in health care. This study reviews the Japanese health care system that limits choosing medical services and the burden of health care costs. The prohibition of mixed treatment can alleviate the out-of-pocket burden in the non-benefit sector, but it can be found that it has a huge limitation in that it places restrictions on choices for both healthcare professionals and patients.

Resource and energy saving is a very important practice for the future as well as for today. Weight saving of structural parts, which are formed by extrusion, plays a key role in manufacturing field. The cross-sections of extruded parts with industrial aluminum are constant in the axial direction by conventional extrusion method. Especially, these aluminum parts used and manufactured in the car industry need other processes to vary the cross-section in the axial direction. However, applications of these parts are often limited by high cost. If the cross-section of the parts is variable by only extrusion with newly developed method, the application of extruded aluminum parts will actually increase. Therefore, a new CNC extruder that can control the section area of a car part was invented for the first time in the nation. Using the extrusion machine, the experiment was performed to validate its workability during the variable section extrusion process. Also, numerical analysis was carried out to investigate the flow mode with different speeds of main ram and various pocket shapes of a die-set in the variable section extrusion process.

A holistic approach to diabetes considers patient preferences, emotional health, living conditions, and other contextual factors, in addition to medication selection. Human and social factors influence treatment adherence and clinical outcomes. Social issues, cost of care, out-of-pocket expenses, pill burden (number and frequency), and injectable drugs such as insulin, can affect adherence. Clinicians can ask about these contextual factors when discussing treatment options with patients. Patients' emotional health can also affect diabetes self-care. Social stressors such as family issues may impair self-care behaviors. Diabetes can also lead to emotional stress. Diabetes distress correlates with worse glycemic control and lower overall well-being. Patient-centered communication can build the foundation of a trusting relationship with the clinician. Respect for patient preferences and fears can build trust. Relevant communication skills include asking open-ended questions, expressing empathy, active listening, and exploring the patient's perspective. Glycemic goals must be personalized based on frailty, the risk of hypoglycemia, and healthy life expectancy. Lifestyle counseling requires a nonjudgmental approach and tactfulness. The art of diabetes care rests on clinicians perceiving a patient's emotional state. Tailoring the level of advice and diabetes targets based on a patient's personal and contextual factors requires mindfulness by clinicians.

Moon Jae-in Government announced the Government's 5-Year Plan on July 19, 2017, President Moon directly announced the Government's Plan for Benefit Expansion in National Health Insurance on August 7, 2017. The main contents of the announced expansion include benefit coverage for all medically necessary services with control over non-covered service occurrence, a decrease in the cost-sharing upper limit, and monetary support for catastrophic medical costs. Although past governments have been continuously striving for benefit expansion in the last 15 years, this plan has its breakthrough aspect in that all medical services will be covered by the National Health Insurance. In alignment, there are important tasks to solve: attaining a proper fee schedule, reforming the healthcare delivery system, and improving healthcare quality. This plan is a symptom oriented action in that it is limited in reducing patients' out-of-pocket money, unlike the systematic approach of the National Health Insurance. The sustainability of the National Health Insurance is being threatened due to South Korea's low birth rate, rapidly aging society, and low economic growth, in addition to the unification issue of the Korean Peninsula, medical utilization of the elderly, management of non-communicable diseases, and so on. Therefore, the Government needs to plan the National Health Insurance system reformation including actions addressed toward medical consumers.
