In these days, the dental market is facing a very difficult management situation for small and medium-sized dental clinics due to overheated competition. Government tries to expand and promote the coverage of non-benefit care and preventive care. In this preventive care area, periodontal disease is ranked as a high frequent disease. Dental clinics will have to come up with a new management strategy to suit this situation. This study therefore conducts analysis of the operational feasibility and strategic plan of the dental prevention center. We use an economic evaluation analysis for three dental clinics currently operating dental prevention centers. First, we itemize benefit and cost field by reviewing literatures and clinic’s second data; Benefit consists of medical profit and others; Cost consists of 1) Labor cost (dentist, dental hygienist, others), 2) Material cost (material medica, medical devices, others), and 3) Maintenance cost. Next, we perform an economic evaluation analysis based on estimated benefit and cost values. There are lots of economic evaluation indicators, but this study selects benefit and cost, net present value, and internal rate of return. The results of the three dental clinics’ dental prevention centers’ B/C, NPV, and IRR all exceed the standard values, indicating economic feasibility; (B/C≧1, NPV≧0, IRR≧R). In detail, A dental clinic’s result shows that B/C=3.07, NPV=1,988,233,000, IRR=95.0%; B dental clinic’s result shows that B/C=2.90, NPV=1,589,604,000, IRR=88.4%; C dental clinic’s result shows that B/C=3.15, NPV=1,494,247,000, IRR=96.4%. Also, IRR value has an more effect to small clinic than bigger one. The Dental Prevention Center could be suggested as a strategic plan to provide a competitive advantage to the dental clinics that struggling as well as the dental clinics newly entering the market in the future.

원종운 ( Jong-un Won ),윤치호 ( Chiho Yoon ),박상찬 ( Sang-chan Park ) 한국품질경영학회 2016 품질경영학회지 Vol.44 No.4
Purpose: The objective of this study is to verify the economic validation of quality management integrated train freight car by analyzing economic evaluation indicators such as benefit and cost, net present value, and inter rate of return. Methods: First, we itemize benefit and cost field by reviewing literatures; Benefit consists of 1)Safety, 2)Operation, and 3)Maintenance; Cost consists of 1)Set-up fee, 2)Wireless internet fee, and 3)Cloud storage using fee. Second, based on these estimated values, we conduct an economic evaluation analysis. Among them, benefit and cost, net present value, and internal rate of return are selected. Results: As a result, all estimated values are highly over criterion of economic validity(B/C?1, NPV?0, IRR? R); 1)benefit over cost ratio is 28.22, 2)Net present value is 8,121.66million KRW, and 3)Internal rate of return value is 2272%. Conclusion: The findings of this study will help making a decision when train industry adopts IoT technology for improving the effectiveness.

Purposes: The objective of this study is to analyze service design process of dental clinic preventive service by using 'Double Diamond Design Process' which is user-centered for improving dental clinic management efficiency. Methodology: We examine case study that dental clinic preventive service of local dental clinic. Following the double diamond design four steps(①discover, ②define, ③develop, ④deliver), we use suitable analytic tools in each steps. In discover step, we perform observation and desk research. Next, in define step, affinity diagram, user persona, and user journey map are performed. We then make service blueprint in develop step. Finally, in deliver step, virtual scenario and confirm some outputs which are based on results of former steps are suggested. Findings: As a result of this study, waiting and consulting phases turn out that these phases are in the most trouble than others. Users(patients) have lots of complain and dissatisfaction in these phases. These touch-points will have to be modified Practical Implication: After checking this study result, it could suggest improvement schemes. To apply these, we try to make some scenarios, and finally realize some outputs. Service design has arisen to strengthen the competitiveness by reflecting user's experience and needs. Especially, service design is not typical, it is so flexible that can apply to various situation and objects. We hope that result of this study is made good use for dental clinics in need.
