During the construction project period, a lot of change orders happen in the design and construction stage Especially, The change order during construction stage causes the huge construction cost increase and duration delay. Accordingly, research on the change order of the construction stage is being progressed relatively active in the design stage, but the design changes are rarely made. In the design stage, the owner has to pay a design addition cost when change order due to the demands of owner happens. However Korea has not the specific standard about design additional cost in design stage. Therefore, this study analyzes problems of design additional cost estimation methods through the case study, and then indicates the method that the ratio distributes to details dividing design tasks and the method of the PM(Project Management). Eventually, this study expects to minimize claim related the design additional cost in design stage.

The government-driven open data policies are on the rise to protect consumers from misunderstandings and monitor the companies. However, in contract-based industries such as insurance, the contract-inherent characteristics make information asymmetry between consumers and companies. Our paper focuses on insurance contracts where the contingency has high uncertainty of occurrence, and the clauses may incur high costs of reading. Given those contracts, we hypothesized that the contract's clear statement decreases customer dissatisfaction and lowers the number of complaints. To empirically support the claim, we collected customers' complaint documents of insurance companies and insurance contracts from 2005 until 2017. Our econometric models showed that clearer statements and words significantly reduce the complaints after controlling for firm-specific heterogeneity and time-specific heterogeneity. We identify that insurance companies' complaint ratio significantly differ depending on the insurance contract, including specific clauses and words.

The purpose of this study was to examine the role of provider practice patterns in the difference in health expenditure between the two types of patients: Health Insurance and Medical Aid type 1. The study used the outpatient claim data for all Medicaid and health insurance patients of hypertension who received medical services from 8,454 primary care physicians during the first half of 2006. The data were stratified by patient's gender and age for the two groups of patients who received care from the same physician. The dependent variables were the differences in medical expenditure per case, patient days per case and medical expenditure per patient day between Medicaid patients and health insurance patients. Empirical results showed that physician characteristics, such as physicians under age 50, greater proportion of pediatric Medicaid patients, lower proportion of new Medicaid patients and the greater number of comorbidity of Medicaid patients are associated with the greater difference between the two types of patients (i.e., greater expenditure of Medicaid patients relative to health insurance patients). This study shows that factors associated with provider practice patterns need to be taken into account in Medicaid policy.

The hospital, clinical department and the physician factor in explaining variations of hospital resource use in surgically admitted patients was compared. This analysis was based on 6, 361 discharges in 28 hospitals for three surgical conditions - lens procedures anal and stomal procedures, uterine and ovarian procedures using medical insurnce claim data. The results were as follows: 1. Regression analysis indicated that the hospital and clinical department characteristics, such as hospital ownership and size, were more significant predictors of the resource use indicators than the physician and patients' social characteristics. 2. Regarding to the physician factors, the hospital where the physician received the residency training and the medical shool where he/she graduated had less effect compared to the hospitals where he/she currently works. Between the residency trained hospital and medical school, the is more important than the latter. 3. When the hospital charges were divided into type of service provided i. e. room, drug, laboratory & radiologic, procedure & operation, and anesthesic charges, variance due to the hospital factor was larger than that due to the physician factor in each item. In summary, the hospital and clinical departmental factor played an important role than physician factor ; indicating to reduce the variation in hospital resource use, the policy that affects hospital behavior would be more effective than that targets individual physician behavior.

Purposes: This study aims to investigate the policy effect of mandatory application of DRG for 7 disease groups in general and tertiary hospitals. Methodology: As DRG was fully implemented in July 2013, this study compares two periods before and after the change(from July 2012 to June 2013, and from July 2013 to June 2014). The benefit claim data of the National Health Insurance Service was used for the comparison. Target patients were those who visited general or tertiary hospitals between July 2012 to June 2014. For pharmaceutical consumption, Interrupted Time Series (ITS) analysis was used to see the effect of DRG mandatory application. Findings: The number of drugs prescribed per patient and pharmaceutical expenditure both showed significant reduction compared to before the DRG implementation. Practical Implications: This study used 2 sets of 1 year period data from before and after the full implementation of DRG to analyze pharmaceutical consumption. When the comparison data accumulates further, it would be possible to conduct more diverse analysis to assess policy effect and to provide way forward for the future.

최근 국내 건설산업 환경의 급격한 변화에 따라 건설업계가 감내해야 하는 어려움이 가중되고 있다. 특히, 발주자의 재무능력 악화로 인한 공사 중단 계약 해제 등으로 건설 클레임이 꾸준히 증가하고 있는 추세이다. 이러한 경우 보증채권자는 클레임을 제기하게 되며 건설업체에 신용을 공여한 보증기관들이 부담해야 하는 대위변제 금액이 증가하고 있다. 그러나, 건설 프로젝트의 성공적 인 수행을 위하여 건설보증이 매우 중요한 역할을 담당하고 있음에도 불구하고 건설보증과 관련된 클레임에 관해 연구 및 실무 차원에서 관심을 크게 받지 못한 실정이다. 따라서, 본 연구에서는 국내 건설보증기관의 클레임 및 분쟁처리 현황을 보증 유형 별로 살펴보고 이에 대한 개선방안을 제시하였다.

Purpose: This study was conducted to identify the prenatal heath care utilization and expenditure among pregnant women. Method: This was a 5-month follow-up study using a stratified sampling and the data were drawn from the "nationwide claim database of Korean National Health Insurance Corporation". Result: This study found that pregnant women were first diagnosed with pregnancy when they were 7.1 weeks pregnant, received 12.7 times of prenatal examinations and 10.6 times of ultrasonogram. It was revealed that 67.5% of the subjects continued to receive prenatal care at the same medical institutions from the diagnosis of pregnancy to the delivery. The study also showed that the total expenditure of prenatal care per pregnant woman was 700,000 Korean Won (KRW) on average and the insurance coverage rate stood at only 20%. Pregnant women living in metropolitan area spent more on prenatal healthcare expenditure than those who living in medium-sized city or rural area. Conclusion: The results of this study implies that the government needs to provide pregnant women with continuous support by increasing health insurance coverage for prenatal care. Especially, it is considered to provide more support to the pregnant women residing in medically underserved areas.
