Purpose: We defined osteoarthritis of the knee as knee pain and crepitus in over 40 years old. The usual clinical manifestation include pain, stiffness, crepitus and loss of function. Methods: We studied 40 cases of the degenerative arthritis of knee clinically. The body mass index(BMI, weight(kg)/height($m^2$) was used as a measure of obesity. Pain self assessment scale by Million Index in according to age, occupation, BMI. Results: Gender by pain self assessment scale was 6.5 in male and 6.6 in female(P<0.05). The prevalence rates obese was 40%. Occupation by pain self assessment scale was 7.0 in Sitting and 5.7 in Standing(P<0.05). Prevalence was increased with age by pain self assessment scale in aged 40-69 years. Conclusion: It has been known that the obesity is one of the predispsing factors of the primary degenerative arthritis of knee. A flexion weight bearing view of the knee obtained at $30^{\circ}$ to $40^{\circ}$ of the joint flexion may be more sensitive in assessing damages to hyaline cartilage because the knee flexion is an important component of the stance phase.

Objectives: Many symptoms of cold and heat patterns are related to the thermoregulation of the body. Thus, we aimed to study the association of cold and heat patterns with anthropometry/body composition. Methods: The cold and heat patterns of 2000 individuals aged 30-55 years were evaluated using a self-administered questionnaire. Results: Among the anthropometric and body composition variables, body mass index (-0.37, 0.39) and fat mass index (-0.35, 0.38) had the highest correlation coefficients with the cold and heat pattern scores after adjustment for age and sex in the cold-heat group, while the correlation coefficients were relatively lower in the non-cold-heat group. In the cold-heat group, the most parsimonious model for the cold pattern with the variables selected by the best subset method and Lasso included sex, body mass index, waist-hip ratio, and extracellular water/total body water (adjusted R² = 0.324), and the model for heat pattern additionally included age (adjusted R² = 0.292). Conclusions: The variables related to obesity and water balance were the most useful for predicting cold and heat patterns. Further studies are required to improve the performance of prediction models.

The following results are achieved from a mortar flow test depending on stainless steel slag fineness, replacement ratio, and a research on material age compressive strength, strength activity index. 1. Flow is proportional to the stainless steel slag fineness within the limits of 4000~8000$\textrm{cm}^2$/g, but in the case of fineness 20000$\textrm{cm}^2$/g flow decreases at all conditions except the case of replacement ratio 10%. 2. As stainless steel slag replacement ratio increases, Mortar of flow somewhat decreases. 3. As stainless steel slag blends, compressive strength decreases, but in proportion to the increase of age, compressive strength increases. 4. As stainless steel slag replacement ratio, compressive strength decreases. 5. In the case of stainless steel slag fineness 6000$\textrm{cm}^2$/g and 20.000$\textrm{cm}^2$/g, compressive strength of revelation ratio has the maximum value when it's replacement ratio is 10%.

This study examined the insolvency of debtors using multiple-indicator approaches and compared the outcomes across income levels with the 2016 'Household Financial and Welfare Survey'. This study used (1) the total debt to total assets ratio (DTA), (2) the total debt service ratio (DSR), and (3) the Household Default Risk Index (HDRI) recently developed by the Bank of Korea. Households in the lowest income quintile were more likely to be insolvent than any other income group. Demographics, such as age and gender of the household head, and most of the financial variables significantly increased the likelihood of insolvency based on the DTA. The number of household members and job status increased the likelihood of insolvency based on the DSR. Also, age, gender of the household head, and most of the financial variables increased the likelihood of household insolvency based on the HDRI after controlling for other demographics and financial variables.

Purpose: The purpose of this study is to know stress and blood stasis pattern for the patients who had hysterectomy related with uterine myoma, adenomyosis, endometriosis. Methods: We got questionnaires from 55 patients among 243 patients who had hysterectomy related with uterine myoma, adenomyosis, endometriosis in the department of obstetrics and gynecology, OO medical center from April 11th 2010 to October 14th 2010, and analyzed them. We conducted correlation analysis between age, pain(VAS), duration of pain and blood stasis score, and between duration of pain, blood stasis score and the sum of Stress Response Index. We compared the sum of Stress Response Index, blood stasis score, VAS according to the result of pathology. For statistics, we used Pearson's correlation coefficient, Mann-Whitney test, oneway analysis of variances(ANOVA) and SPSS version 17.0 for windows. Results: The correlation between duration of pain and blood stasis score showed statistical significance. The correlation between sum of the Stress Response Index and blood stasis score showed statistical significance. There is no statistically correlation between age, VAS, duration of the pain and blood stasis score. There is no statistically significant difference in sum of Stress Response Index, blood stasis score, VAS according to the result of pathology. Conclusion: The result showed that Stress is related with static blood, and the longer patients suffer from pain, the easier patients' blood to be static. Further study will be needed.

The study was conducted to assess the association or physical activity, television watching and energy intake with body fat in 514 adolescents(218 boys, 296 girls) aged 14-17 years. Comparison of the weight status evaluated according to some indicators based on weight and stature was made. The quantitative food frequency was used to determine intakes of total energy and energy from each macronutrient. Television-watching time was used as an index of inactivity and time spent performing extra-curricular physical exercise or playing was used a index of activity, BMI(body mass index) was used as index of body fat. Weight status varied by the indicators used. Using BMI, Broca and Rohrer index, 54-59% of boys and 38-57% of girls were underweight decreased(23% of boys and 26% of girls) and the of overweight increased (9.3% of boys and 7.8% girls), when adolescents whose BMI are<=15th percentiles for age and sex, and >= 85th percentiles of standard growth charts of Korean Children and aldosescents(1998) were classified as underweight and overweight, respectively, Girls tended to get fatter compared to boys who showed greater skeletal development. There were no significant correlations between BMI and total energy intake, energy intakes from macronutrient and physical activity level. These lack of association seems to be related to indication that BMI reflects total body mass rather than fatness. Mpreover, the effect of growth may interact with diet intake or physical activity level. Although BMI was not related to physical activity, television-watching time was negatively correlated with physical activity. Television-watching time was positiviely correlated with energy intake in girls. In adolescents, criteria for weigh status based on weight and stature must be age- and sex-specific in that weight status varied by indicators whether gender and higher were taken into consideration or not. If follows that each hourly increment of television watching may be related to fatness of adolescents, because hours certainly reduce the opportunity to be active and increase th energy intake.(Korean J Nutrition 34(1):39-47, 2001)

Although several studies have assessed the influence of the glycemic index on body weight and blood pressure among adults, limited evidence exists for the pediatric age population. In the current study, we compared the effects of low glycemic index (LGI) diet to the healthy nutritional recommendation (HNR)-based diet on obesity and blood pressure among adolescent girls in pubertal ages. This 10-week parallel randomized clinical trial comprised of 50 overweight or obese and sexually mature girls less than 18 years of age years, who were randomly assigned to LGI or HNR-based diet. Macronutrient distribution was equivalently prescribed in both groups. Blood pressure, weight and waist circumference were measured at baseline and after intervention. Of the 50 participants, 41 subjects (include 82%) completed the study. The GI of the diet in the LGI group was $42.67{\pm}0.067$. A within-group analysis illustrated that in comparison to the baseline values, the body weight and body mass index (not waist circumference and blood pressure) decreased significantly after the intervention in both groups (P = 0.0001). The percent changes of the body weight status, waist circumference and blood pressure were compared between the two groups and the findings did not show any difference between the LGI diet consumers and those in the HNR group. In comparison to the HNR, LGI diet could not change the weight and blood pressure following a 10-week intervention. Further longitudinal studies with a long-term follow up should be conducted in this regard.

Thirteen sternocosal elevations for pectus excavatum were performed on twelve patients between Jan 1989 and Sep. 1991. Eleven among the twleve patients were male. The subjects ranged in age from 2 years to 20 years, with a mean age of 8.33 years[SD=4.80 years], Eleven patients were below 15 years. The early postoperative evaluation by Humphreys` criteria except keloid formation was excellent in all the patients. The lower vertebral index[LVI], configuration index[CI], and upper vertebral index[UVI] were measured on the lateral chest roentgenogram. The LVI and CI improved significantly from 0.31$\pm$0.06 and 1.14$\pm$0.06 preoperatively to 0.25$\pm$0.03 and 0.78$\pm$1.10 postoperatively. The degrees of depression, flatness, and asymmetry and funnel index were measured at the most deformed portion on the computed tomgram performed pre- and postoperatively. The degrees of depression and funnel index improved significantly from 3.32$\pm$0.73 and 5.77$\pm$1. 54 preoperatively to 1.85$\pm$0.14 and 2.96$\pm$0.43 postoperatively, There was no significant change in the degree of flatness however, Six postoperative morbidities occurred in five patients Three were superficial wound infection, two hemopneumothorax, and one reoeration, Reoperation was performed due to forward displacement of the distal sternum below the posterior sternotomy, The findings of this study suggest that the sternocostal elevation is an excellent primary method for the pectus excavatum of children and young adolescents.

Purpose: The study was conducted to describe body shapes of school age children using the degree of obesity index (DOI) and body mass index obesity index classified by the Ministry of Education, Science and Technology (M-BOI) and Seoul Metropolitan Office of Education (S-BOI). Methods: In this cross sectional descriptive study health screening data for school children collected in 2007 was used. Results: Data were analyzed for 2,193 4th-6th grade boys (52%) and girls who attended 4 schools in rural areas. DOI determined that only 44.3% of students had average weight. This proportion was much lower than the results of other methods (74.3-77.6%). All three methods defined girls (51.3-61.8%) as skinnier than boys. Skinny and average body shaped children classified by DOI and obese children classified by S-BOI were heavier and taller and presented higher degrees of obesity (DO) and BMI scores than by other methods. M-BOI and S-BOI presented statistically significant positive correlations with weight, height, DO and BMI, while DOI was not correlated with height. Conclusion: BMI based body shape classifications provide a more rigorous classification of body shape which are favorable for school health professionals with limited resources and policy makers for internationally comparable references.
