Background: The low benefit coverage rate of South Korea's health security system causes catastrophic health expenditure. And catastrophic health expenditure can be the cause of the transition to and persistence of poverty. This study was conducted to ascertain the effect of catastrophic health expenditure on the transition to and persistence of poverty, using 6 years of the Korea Welfare Panel Study Data. Methods: This study was conducted among the 22,528 households that participated in the Korea Welfare Panel Study, 2007-2012. Catastrophic health expenditure was defined as equal to or exceeds thresholds (10%, 20%, 30%, and 40%) of household's capacity to pay. The effect of catastrophic health expenditure on the transition to and persistence of poverty was ascertained via multivariate logistic regression. Results: Four-point-seven percent to 20.6% of the households are facing catastrophic health expenditure. Rates of the transition to (relative risk [RR], 18.6 to 30.2) and persistence of (RR, 74.8 to 76.0) poverty of households facing catastrophic health expenditure was higher than households not facing catastrophic health expenditure. Even after adjusting the characteristics of the household and the household head, catastrophic health expenditure was found to affect transition to (odds ratio [OR], 2.11 to 3.04) and persistence of (OR, 1.53 to 1.70) poverty. Conclusion: To prevent catastrophic health expenditure and transition to and persistence of poverty resulting from catastrophic health expenditure, the reinforcement of South Korea's health security system including the benefit coverage enhancement is required.

Objectives: The purpose of this study was to compare predictions and measurements of the resting energy expenditure (REE) of overweight and obese adult women in Korea. Methods: The subjects included 65 overweight or obese adult women ranging in age from 20~60 with a recorded body mass index (BMI) of 23 or higher. Their height, weight, waist-hip ratio, and blood pressure were measured. The investigator also measured their body fat, body fat percentage, and body composition of total weight without fat using Dual energy X-ray absorptiometry (DXA) and measured resting energy expenditure by indirect calorimetry. Measured resting energy expenditures were compared with predictions from six methods: Harris-Benedict, Mifflin, Owen, WHO-WH, Henry-WH, and KDRI. Results: Harris-Benedict predictions showed the smallest differences from measured resting energy expenditure at an accurate prediction rate of 70%. The study analyzed regression between measured resting energy expenditure and body measurements including height, weight and age. The formula proposed by this research is as follows: Proposed REE equation for overweight and obese Korean women = $721-(1.5{\times}age)+(0.4{\times}height)+(9.9{\times}weight)$. Conclusions: These findings suggest that age is a significant variable when predicting resting energy expenditure in overweight and obese women. Therefore, prediction of resting energy expenditure should consider age when determining energy requirements in overweight and obese women.

Meals served in school cafeteria for teachers were evaluated in terms of calorie and nutrient level and food composition. Daily energy expenditure of teachers was compared with caloric content of the meal. The followings are results of the study. 1) Twelve different foodstuffs were used in each meal of school cafeteria for teachers. The average amount of food served meal was 396.0g. The ratio of animal food to total food served was 13.2%. The meal was consisted of 44.8% of basic food group 4, 34.7% of basic food group 3, 19.3% of basic food group 1, 0.4% of basic food group 2 and 0.9% of basic food group 5. 2) The average caloric content of the meal was 629.9Kcal. The caloric ratio of carbohydrate, protein and fat to total calorie was 72.4% : 15.3% : 12.3% respectively. The ratio of animal protein to total protein was 43.2%. In meals of school cafeteria, the level o fall nutrients except iron and niacin was lower than RDA for male, whereas the level of all nutrients except protein and niacin was lower than RDA for female. 3) The average daily energy expenditures of teachers were 2,017.2Kcal for male and 1,735.3Kcal for female. The meal in school cafeteria supplied 93.7% of daily energy expenditure of male teachers and 110.0% of daily energy expenditure of female teachers. When planning meals in school cafeteria, recommended allowance, actual energy expenditure and food preference of teachers should be considered to improve the quality of meals. Also it seems desirable to give teachers the nutritional education for taking balanced diet.

Fiscal crisis in the medical insurance system has put the pressure upon hospitals by increasing the rate of curtailment, since the implementation of the separation of prescription and dispensing of medicine. The purpose of this study is to analyse the curtailment of mdical and drug expenditure before and after the system of separation between prescribing and dispensing and to suggest the problems about current inspection system. Data were obtained from 13 general hospitals and used for analysis of trends on medical & drug expenditure, and curtailment in 1999-2000 at three months intervals. The results were as follows; The scale of curtailment for drug expenditure has been increased on outpatient and inpatient since 2000. For the curtailed drug cost with outpatient, the ratio of curtailed drug expenditure has been increased in the case of prescription within the hospital. These results suggest that review system in social insurance were over-focused to control the cost and it might to impede the validity of review function in insurance system. Therefore, it' s needed to develope the scientific and reasonable criteria for Inspection and evaluation of durg expenditure.

The purpose of this study was to find the characteristics of university education expenditure and how university education expenditure affected household finance such as total household expenditure after excluding education expenditure, savings, and debts respectively. The data were drawn from the 8th Korean Labor & Income Panel Study conducted by the Korean Labor Institute, and 563 households with children attending university were selected. The t-test, F-test (Duncan's multiple range test as post hoc test), OLS, and Heckman's two-step estimation were utilized by SAS 9.1 and SPSS 12.0 for Windows. The results were as follows: First, average annual tuition was found to be 6,170,000won(21.5% of total annual household expenditures) and average annual private education expenses were 4,920,000won(15.9% of total annual household expenditures). Second, the higher the household income levels, the more spent on university education, whereas the higher the household income level, the lower the household expenditure-to-university education ratio. Third, tuition and private education expenses had a negative impact on household expenditures after excluding education expenditure.

The purpose of this study is to examine the changes in financial structure of the self-employed brought on the economic crisis in Korea.. We use financial ratio analysis, such as income to expenditure ratio, liquidity ratio, debt ratio, and capital accumulation ratio to analyze financial well-being of self-employed households. This study used a 1997 and 1998 Korean Household Panel Study collected by Daewoo Economic Research Institute. The average amount of holding of each type of asset showed that the investment of self-employed households decreased in the banking industry and the stock market in 1998 compared to 1997. On the other hand, asset allocation in bond and real estate increased, which implied preference for a stable type of asset with the increase in uncertainty of the future and economic instability. Devaluation of real estate allowed households to easily obtain real estate and increase preference for asset allocation in real estate after the crisis. The changes in financial ratio for the year 1998 shows that such ratios as income to expenditure, liquidity, and capital accumulation, decreased compared to the year 1997. Among those ratios, the income to expenditure ratio showed the biggest decline because of reduced income of self employed households. The results implied that the income structure of the self-employed is unstable, thus the self-employed were likely to be greatly affected during the economic downturn. Earners have more average income and net assets than the self-employed. However, using financial ratios, it was found that self-employed households were more stable than employees. The results shows that the financial ratio analysis is better tool to estimate households financial status. Implications for financial educators, counselors, and planners are offered. The results will provide implications for policy makers to establish appropriate policies for the self-employed and help them financially survive.

This study was performed in order to compare a change in pharmaceutical expenditures per outpatient of clinic and to analyze factors relevant to a systems as part of evaluating policies for the incentive scheme to reduce total prescribed drug expenditure and for the drug utilization review system("DUR system" hereafter). For this, it had finally analytical subjects as 21,320 clinics nationwide without a change in location, clinics symbol and signed subject during both terms of the first half of 2010 and the first half of 2011. As a result, the odds ratio with reduction in pharmaceutical expenditures of clinic was statistically higher significantly in the shorter year number of opening clinic, in the larger number of doctors, when the classification of establishment is other, not individual, and when the signed subject is surgical division. Also, the odds ratio was significantly higher in the less patient number of clinic and in the lower ratio of patients aged over 65. Finally, the odds ratio was significantly high when a clinic had been located in DUR system demonstrative project area. Through this, a case of policy for improvement in doctor's autonomous prescription behavior like DUR system can be known to be effective for reduction in pharmaceutical expenditures. A future research on evaluation of policy for pharmaceutical expenditure management system will need to be performed in-depth analysis in consideration of diverse characteristics on the participatory entities.

Physiological analysis of the physical exercise was made on 9 subjects performing mountain climbing. The course between two points (256 and 516 meters altitude) was 1,300 meters in distance and difference of vertical height was 260 meters making the mean grade of 20%. In the field, the heart rates during uphill or downhill walk were recorded by EKG radio-telemetry. In the laboratory, oxygen consumption was obtained by the recorded heart rates, using individual heart rate vs oxygen consumption diagram obtained by treadmill test. the following results were obtained. 1. Uphill walk time was 36.5 minutes, and during this period the mean heart rate was 149.0 heats/min and peak heart rate was 169.2 beats/min. The total heart beats during the uphill walk was 5.433 beats. 2. The ratio of individual mean heart rate during the uphill walk to the maximal heart rate distributed between 66.6% and 98.3%, and the mean of the total group was 83.1%. The ratio of peak heart rate of uphill walk to the maximal heart rate was 94.5% in the group. Thus uphill walk of a 20% grade mountain course was an exhaustive exercise. 3. Oxygen consumption during uphill walk was 2.22 l/min (ranged between 1.79 and 2.70 l/min) and the ratio of this to the resting oxygen consumption was 8.31. The peak value of oxygen consumption during uphill walk was 2.73 l/min and the ratio of this to the resting oxygen consumption was 10.39. 4. Energy expenditure during uphill walk showed a mean of 11.1 kcal/min and the peak expenditure rate was 13.6 kcal/min. The total energy expenditure during 36.5 minutes of uphill walk was 396 kcal. 5. In downhill walk, the time was 31.7 minutes, mean heart rate was 118.4 (ranged between 100.1 and 142.7) beats/min, and the peak heart rate was only 129.4 beats/min. The ratio of mean heart rate to the maximal heart rate was 66.3%. Total heart beats during downhill walk was 3,710 beats. The ratio of downhill oxygen consumption to the resting consumption was 5.70. The rate of energy expenditure was 7.5 kcal/min, and the total onery expenditure during the 31.7 minutes of downhill walk was 228 kcal. 6. The effect of training was manifest in the uphill walk and not in the downhill walk. After training in mountain course walk, i) the uphill time was shortened, ii) mean heart rate increased, iii) time vs heart rate curve became smooth and showed less frequent zig-zag, i.e., the depth of trough on the curve decreased and the magnitude was less than 10 beats. In non-trained subject the depth of trough on the curve was greater than 50 beats and appeared more frequently. 7. Mountain climbing is a good health promotion exercise. For the promotion of health the reasonable amount of uphill mountain walk exercise in a 20% grade course is a walk for 40 or 50 minutes duration once a week.

In this paper, we use a structural equation model to diagnose success factors on commercialization of information and communication technology considering the characteristics of commercialization process in terms of the type of technology, technology provider and technology receiver. The results of our study indicated the following. The transferor's research ability has significant effects on the commercialization by small businesses with low R&D expenditure to sales ratio, and the business management ability plays an important role in the commercialization by the relatively large (over 100 employees) companies with low R&D expenditure ratio. During the commercialization of the technology independently researched by government run institute or university, the transferee's business management ability is crucial to success. To those companies which run the existing business with high R&D expenditure ratio, their ability to utilize technology is essential. When the independently researched technology is used in the new business, the companies' business management ability and the role of technology transfer center are the important factors on the commercialization. Based on these findings, we suggest some strategies to effectively promote R&D efforts for successful commercialization.
