This study estimated the WTP( Willingness-to-pay) for reducing the risk of foodborne disease using contingent valuation method. WTP is elicited with double-bounded dichotomous choice questions in which respondents(selected from the Seoul population using survey design and are aged above 19, n=499) decided whether to purchase a more expensive food to reduce the risk of foodborne disease. For data analyses, the study employed a relative likelihoods of the Interval-data Model Method and Bayesian estimation method. The study found that bids, income, age and education were associated with the probability of higher WTP for reducing the risk of foodborne disease. Respondents answered that they would be willing to pay minimum 3, 108[2, 759, 3, 454] ~ maximum 3, 99713, 101, 4, 752] Korean won.

Objectives : The aims of this paper were to develop the composite deprivation index (CDI) for the sub-district (Eup-Myen-Dong) levels based on the theory of social exclusion and to explore the relationship between the CDI and the standardized mortality ratio (SMR). Methods : The paper calculated the age adjusted SMR and we included five dimensions of social exclusion for CDI; unemployment, poverty, housing, labor and social network. The proxy variables of the five dimensions were the proportion of unemployed males, the percent of recipients receiving National Basic Livelihood Security Act benefits, the proportion of households under the minimum housing standard, the proportion of people with a low social class and the proportion of single-parent household. All the variables were standardized using geometric transformation and then we summed up them for a single index. The paper utilized the 2004-2006 National Death Registry data, the 2003-2006 national residents' registration data, the 2005 Population Census data and the 2005-2006 means-tested benefit recipients' data. Results : The figures were 115.6, 105.8 and 105.1 for the CDI of metropolitan areas (big cities), middle size cities and rural areas, respectively. The distributional variation of the CDI was the highest in metropolitan areas (8.9 - 353.7) and the lowest was in the rural areas (26.8 - 209.7). The extent and relative differences of deprivation increased with urbanization. Compared to the Townsend and Carstairs index, the CDI better represented the characteristics of rural deprivation. The correlation with the SMR was statistically significant and the direction of the CDI effects on the SMR was in accordance with that of the previous studies. Conclusions : The study findings indicated mortality inequalities due to the difference in the CDI. Despite the attempt to improve deprivation measures, further research is warranted for the consensus development of a deprivation index.

Objectives: This study estimated the annual socioeconomic costs of food-borne disease in 2008 from a societal perspective and using a cost-of-illness method. Methods: Our model employed a comprehensive set of diagnostic disease codes to define food-borne diseases with using the Korea National Health Insurance (KNHI) reimbursement data. This study classified the food borne illness as three types of symptoms according to the severity of the illness: mild, moderate, severe. In addition to the traditional method of assessing the cost-of-illness, the study included measures to account for the lost quality of life. We estimated the cost of the lost quality of life using quality-adjusted life years and a visual analog scale. The direct cost included medical and medication costs, and the non-medical costs included transportation costs, caregiver's cost and administration costs. The lost productivity costs included lost workdays due to illness and lost earnings due to premature death. Results: The study found the estimated annual socioeconomic costs of food-borne disease in 2008 were 954.9 billion won (735.3 billion won-996.9 billion won). The medical cost was 73.4 -76.8% of the cost, the lost productivity cost was 22.6% and the cost of the lost quality of life was 26.0%. Conclusions: Most of the cost-of-illness studies are known to have underestimated the actual socioeconomic costs of the subjects, and these studies excluded many important social costs, such as the value of pain, suffering and functional disability. The study addressed the uncertainty related to estimating the socioeconomic costs of food-borne disease as well as the updated cost estimates. Our estimates could contribute to develop and evaluate policies for food-borne disease.

The purpose of this study was to examine the regional disparity of ambulatory health care utilization considering spatio-temporal variation in South Korea during 1996-2008(precisely, in 1996, 1999, 2002, 2005, and 2008) using bayesian hierarchial spatio-temporal model. The spatial pattern uses an intrinsic gaussian conditional autoregressive (CAR) error component. Ornstein-Uhlenbeck method was applied to detect the temporal patterns. The results showed that substantial temporalgeographical variation depending on diseases exists in Korea. On the Contrary to the pattern of total outpatient utilizations, for example, the areas that chronic diseases distributed relatively high were most in rural where the proportion of elderly population was higher than in the urban. Chungcheongnam-do, Junlabuk-do, and Kyeongsangbuk-do had higher risks in hypertension, whereas arthritis was higher risk in the Kyeonggi-do, Chungcheongbuk-do, Junlanam-do, and Junlabuk-do. The results of this study suggested that the effective health intervention programmes needed to alleviate the regional variation of health care utilization. These outcomes also provided the foundation for further investigation of risk factors and interventions in these high-risk areas.

우리나라는 2004년부터 지금까지 OECD 국가 가운데 자살사망률 1위이며, 지속적으로 자살자 수와 자살 사망률이 증가하고 있다. 효과적인 자살정책을 확인하기 위해 AHP(Analytic Hierarchy Process) 기법을 이용하여 자살예방의 주요 접근방법별 세부정책들의 우선순위를 조사하였다. 설문은 2013년 8월 23일, 26일 두 차례에 걸쳐 총 30명을 대상으로 워크숍 형식으로 실시하였다. 이중 학계는 20명(사회복지사 4명, 정신보건학자 7명, 정신의학자 5명, 임상심리학자 4명), 정책결정자는 5명, 공급자는 5명이였다. 2013년 9월 9일부터 12일까지 4일간 이메일로 사회복지분야와 임상심리분야에서 각각 5명씩 추가하여 총 40명을 대상으로 조사를 하였다. 세부 정책들의 중요도는 ‘자살시도자 관리,’ ‘공공자살예방서비스 인프라 구축,’ ‘유가족 지원사업,’ ‘위험집단의 위기관리’ 등의 정책에서 높은 것으로 나타났다. Since 2004 suicide in Korea was the number 1 cause of mortality among OECD countries, the suicides and suicide mortality rate is constantly increasing. Using AHP(Analytic Hierarchy Process), we examined the main approaches and detailed policies of suicide prevention to confirm an effective suicide policy. A workshop and survey were conducted on August 23rd and 26th, 2013, with 30 people. There were 20 academics (4 social workers, 7 mental health workers, 5 psychiatrists, 4 clinical psychologists), and 5 policymakers and 5 administrative staff. In additional 5 people from social welfare and 5 from clinical psychology fields were survey from september 9 to 12 by e-mail. The research found 4 priorities. They include, suicide attempt management, building up public infrastructure for suicide prevention, support to bereaved families, and crisis management of high risk groups in society.

Background: Antibiotic resistance has been becoming serious challenge to human beings. Overuse of antibiotics, especially, for infants is concerned, but studies are very few for the prescribing pattern of antibiotic use for infants. This study analyzes prescribing patterns of antibiotics in outpatients of preschool children with acute respiratory tract infections in South Korea. Methods: Data are used from 2011 Health Insurance Review & Assessment Services-pediatric patients sample. Inclusion criteria is outpatient children (0 to 5 years) with top five frequent diseases. Prescription rates are analyzed by types of disease, provider, specialty, region, and ages. Binary or multinomial logit models are used to analyze determinants of providers’ prescription pattern. Results: The main findings are as follows. First, distributions of prescription rates are shown as L-shape or M-shape depending on the types of disease. Second, the prescription variation is so large among providers, where providers are polarized as a group with low prescription rates and the other group with high prescription rates, though the shapes are shown diversified across types of disease. Third, prescription rates appear to be lower in pediatrics and higher in ENT (ear-nose-throat). Fourth, broad spectrum antibiotics are widely used among children. Finally, the logit analysis shows similar results with descriptive statistics, but partly different results across types of disease. Conclusion: Antibiotics for respiratory tract infections of infants are used excessively with a large variation among providers, and especially broad spectrum antibiotics are used. The prescription guideline for antibiotics should be provided for each specific disease to reduce antibiotic resistance in the future.
