Background: The purpose of this study is to analyze the cost for the denture treatment in accordance with the government's plan to expand the National Health Insurance coverage for dental prothesis from July 1, 2012. Methods: We developed the draft of classification of the treatment activities based on the existing researches and expert's review and finalized the standard procedures through confirming by Korean Dental Association. We also made the list of input at each stage of treatments. We conducted survey of 100 dental clinics via post from April 4 to May 20 in 2011 and 37 clinics took part in the survey. The unit of cost calculation is the process from the first visit for denture treatment to setting of denture and adjustment. The manufacturing process performed by dental technician was not included in the cost analysis. Results: The process for the complete denture treatment was classified with 10 stages. The partial denture treatment was classified with 8 stages. The treatment time per each denture is about 5.6 hours for complete dentures and about 6.6 hours for partial dentures. The treatment cost were from 591,108 won to 643,913 won for complete denture and from 670,219 won to 738,840 won for partial denture in 2011, depending on the location, type of the clinics and the types of physician's income. Conclusion: This study shows the example of cost analysis for the treatment to set the fee schedule. Measures to get representative and accurate information need to be made.

This paper constructs the two-part tax-a combined form of output tax and entrance fee-for polluting oligopolists under endogenous entry. In the presence of external damage that varies exogenously with aggregate output, we show that the two-part tax produces the ex post Pigouvian rule and thus achieves the first-best optimum. We also examine a detailed analysis of the impact of the two-part tax on social welfare and government revenues. Finally, when estimation errors exist in the process of regulation, we identify the incentive conflicts between interest groups and analyze the effects of estimation errors on determining optimal tax. In particular, we show that if the regulator takes care of both welfare loss and revenue gain under the proposed two-part tax, not only over-estimation on the slope of external damage but also under-estimation on the slope of market demand should be taken into the policy consideration.

Purpose: This study was to classify patient severity score for hemodialysis patients. Method: The subject of this study was 1,575 patients. To study the severity of the patients, we used t-test and ANOVA. The congruity was measured by Kappa coefficient and the severity in each medical facility was analyzed by ANOVA. Result: The results showed that there was a significant difference according to the levels of medical center (F=171.187, p<.0001). Categorizing the severity of the patients in each medical facility, group II and III of the secondary medical institution had higher ratio than the primary medical institution. There was not a single patient coming under group IV in both of the primary or secondary medical institutions. However, the tertiary medical institutions had more subjects in group II and III than the primary and secondary medical institutions. The group IV with the highest severity had 11 patients(1.5%), demonstrating that the tertiary medical institution had higher severity patients than the primary or secondary medical institutions. Conclusion: The results of this study appropriately reflects the repayment system of medical expenses by the government. Also, it provides the fundamental information to develop nursing fee system taken into account of the systemic differences among the primary, secondary and tertiary medical institutions.

This paper studies the effect of industrial waste water effluent charge reform. The goal of the present effluent charge system is to use environmental resources in an efficient way by charging the cost for removing emitted water pollutants. However, the present system is a type of regulation instead of providing economic incentives to the industry. That is, if a firm emits pollutants greater than the limit, it has to pay an amount greater than the cost of cleaning them taking into account the amount of waste water discharged, region, the number of violation and the level of density of pollutants. However, the excessive fees have resulted in the lowest ratio of revenue-to-effluent charge among all environmental charges. The paper estimates the effect of the change in effluent fee and revenue when the present effluent charge system is converted to one that offers economic incentives. The results show that the amount of waste water effluent charge is about four times larger than the estimated environmental cleaning cost. In addition, the results show that by modifying the effluent charge system, the ratio of revenue to effluent charge can be raised.

Background: It is widely acknowledged that single bedrooms have many potential advantages compared to multiple bedrooms. However, Korea has a reimbursement system that patients have to pay the additional fee if they will use single bedroom or pay-bed (1-3 bedroom). There is little research on patients' bed selection and relationship between patient satisfaction and bed type in the Korean setting. Methods: Using the 2017 Korea Health Panel (KHP) Survey data, we modified bed type by two dichotomous variables: single bedroom vs. multiple bedroom (2+ bedrooms) and pay-bed (1-3 bedroom) vs. reimbursed bed (4+ bedroom). Multivariate logistic regression is performed to determine the factors affecting the patient's choice of room types. Multivariate regression analysis was conducted to examine how hospital room types are affecting patient satisfaction. Results: Single room and pay-bed (1-3 bedroom) use was influenced by patient age (19- years old), male, a person at work, hospitalizing in a clinic, and birth. After controlling variables of the behavioral model of medical utilization, the association between patient satisfaction and use of single bedroom & pay-bed (1-3 bedroom). Cause of hospitalization, major treatment, and recognition of unnecessary care are statistically significant variables on patient satisfaction. Conclusion: Although the single room is about the standard for newly built hospitals in western countries, it remains unclear that single room or pay-bed (1-3 bedroom) has positive effects on patient's outcomes and satisfaction. In this empirical study, the difference in patient satisfaction by bedroom type was not noticeable. In terms of bed management by hospital staff, securing patient credibility in hospital care is an important task. Patients' perception of whether medical staffs have encouraged unnecessary treatment or tests has a significant impact on patient's satisfaction.

The existing cost calculation standard for the implementation project to manage total maximum daily loads calculates cost by considering the area scale and the population based on the basic cost. This method renders it difficult to calculate cost when the detailed characteristics of a business are considered. Therefore, in this study, we proposed a costing method that applied the standard fee calculation, reflecting the area scale, a number of human and livestock, wastewater discharge facilities, etc. And, through the review of related order cases, the suitability of factors affecting the implementation project is verified and the appropriateness of the cost calculation method is verified.

This paper estimates the price of standard waste bags that satisfies the polluter pays principle. Unlike previous studies, this paper suggests a method that can find new equilibrium prices using a structural relationship between the demand and cost function for the wastes. To do this, we employ the fixed-point iteration. The main findings of this paper are as follows. Assuming that the polluter pays principle is achieved at the average cost for the waste treatment, the price need to be set at a level about 3.12 times higher than the current one. The estimation result using a structural model, however, shows that the price should be set at a level four times higher than the present. This results are because the quantities reduced of the wastes make the cost per quantity of wastes due to the fixed costs increase. If applying the estimated price to the demand function, the amount of discharge of waste generated nationwide can be reduced by 10%.

Caffe Bene, one of the most notable coffeehouse chain brands in Republic of Korea, gives us some thought-provoking issues in terms of sustainable success. Despite harsh competition among various coffeehouse brands, Caffe Bene has been accomplished astonishing outcomes in domestic market and now ranked 2^nd place in sales among the global coffeehouse franchise in 2010 and 2011. These achievements were possible mainly because Caffe Bene adopted distinctive shop design, maintained aggressive marketing strategy, developed new menu, and combined the unique Korean culture with ordinary concept of café to make its place attractive. However, since Korean coffeehouse market is getting saturated and consumers are becoming savvy about coffee, Caffe Bene needs to find a new solution to overcome growth stagnation. Besides, many experts pointed out that irrational increase in the number of stores might hurt its business in the aspect of managing distribution channel and providing consistent services. Also, customers of Caffe Bene have shown that it has to complement its critical weaknesses: inferior coffee taste and relatively high price for a cup of coffee. Especially, some people view that the company is shifting its high rental fee, interior cost and PPL marketing cost to consumers by charging high price for coffee. To get over the problems, Caffe Bene is currently using C/S Consumer Management System though experts are questioning about the efficacy because of the conflict between purpose of the system and the headquarters' plan. Present CEO Kim also announced that the company will complete its logistics system in the latter half of 2012 to provide stores with more high quality coffee beans to improve taste of coffee. Thus, in this case, we describe how Caffe Bene succeeded in Korean market and enumerate its key success factors. Also, we specify the long-term goals of Caffe Bene and introduce the current policies and strategies to show how the company is working on to achieve its ultimate goal. By reading and analyzing this business case, students could get useful insights regarding franchise management and think about issues on competing in a saturated market. Also, it would be worthwhile to generate creative solutions for the problems that Caffe Bene is now facing to broaden the practical perspective.

In order to improve the waste management system for the unit of small villages, we visited 14 counties nationwide and investigated the present conditions of the farming and fishing villages on waste management. First, we selected one concentrated residential type village and one separated residential type village. Then we investigated the quantities and the characteristics of the domestic wastes generated from the 2 sample villages that we chose early on. The concentration of 7 heavy metals in open burned residuals was analyzed. The results are as follows: (1) We distributed the 799 questionnaires to public servants (83 Gun, 716 Myon) and 337 questionnaires to residents. In accordance with a result of questionnaire on the Volume-Based Waste Fee System, the rate of participated questionnaire was 70.3% from public servants and 31.8% from residents. (2) From the survey on two chosen villages, the generation of municipal waste was 48.6g/person/day in A Village, 54.3g/person/day in B Village. This amount was smaller than that of national average of 1.05kg because of excluding recyclable wastes and some of incinerated combustible waste. (3) The 14 counties entered the aged society. There were 2 aging societies, 8 aged societies and 4 super-aged societies. And the average ratios of Public financial independence and waste budget of financial independence were 16.1% and 17.9% respectively. These are lower than that of national average of 57.2% and 31.4%. This indicates that these factors seemed to be operated with the hindrance insettling Volume-Based Waste Fee System in the small villages.

The purpose of this study is to suggest an improvement plan for the calculation method of the engineer standard wage rate (ESWR) and to compute a reasonable ESWR. To this end, an adequacy review of theESWR calculation criteria was conducted along with an extensive engineering industry survey. The survey results were analyzed using an effective response sample of 748 companies out of 1,000 survey samples extracted by stratifying the 5,879 survey population. The main results were as follows. ①When calculating the engineering service fee, the prime contractor's engineer wage is suitable for the ESWR. The ESWR can be estimated by the formula 'average wage÷[1-proportion of subcontract orders×(1-subcontract rate)].' ② The field survey showed that the number of monthly working days was 20.35-20.54 days at 99 % confidence interval, which was significantly different from the current standard (22 days). In addition, as a result of a legal review of the ESWR criteria, it was found that the number of working days should be calculated in accordance with the Labor Standards Act after 2022. ③ Applying government guidelines, the time difference between the wage survey and the ESWR application can be corrected by the past ESWR increase rate for a specific period. ④ Using modeling based on the analysis above, the current ESWR was 13.5-14.5 % lower than the appropriate level. A lower ESWR was driven by the non-reflection of subcontract structure (4.1 %), overestimation of monthly work days (6.8-7.8 %), and application of past wage (2.6 %). The proposed model is expected to be widely used in policy making, as it can provide a useful framework for calculating the standard wage rate in similar industries as well as calculating appropriate engineering fees.
