  • A study on cooperative medical treatment system between oriental and western medical practitioners was conducted from March through August 1997 in order to determine a productive model of cooperation of two medical parts for treatment of patients. Questionnaires were distributed to 195 medical doctors(M.D.) and 195 doctors of oriental medicine(O.M.D.) working in clinics and hospitals in six major cities. Statistical analysis tools used for this study were frequency, t-test and multiple regression by using SPSS/P.C package. The results are summarized as follows: 1. The respondents were composed of male docotors(78%) and female doctors(22%) and 68.2% of M.D. and 97% of O.M.D. were interested in the other medical part. The doctors of both disciplines had some limitation on treatment of patients but they were reluctant to refer their patients to other doctors in different discipline. 2. M.D assumed that oriental medicine was more effective for chronic diseases, and O.M.D. thought that western medicine was more effective for acute diseases. 92.3% of O.M.D.s responded that even though they do not utilize western medical technology for diagnosis, they believed the results of diagnoses by western medical technology. 3. 60.5% of O.M. and 93.3% of O.M.D. said that cooperative medical treatment system could be necessary for patients and it would be effective for control of diseases and 69% of western medical doctors and 99% of oriental medical doctors agreed that oriental medical practice would be more effective for cerebellar vascular accidents than other diseases. 77.4% of western medical doctors and 92.3% of oriental medical doctors responded that the students of two different disciplines have to be taught on the other disciplines. 82.6% of western medical doctors and 83.3% oriental medical doctors agreed that it would be necessary to have collaborative research between scientists in two disciplines. 81.5% of M.D.s and 93.3% of O.M.D.s believed that they had prejudice and distrust on other discipline 4.90% of the doctors were not satisfied with the government medical policies on health insurance, legal matters, and health delivery system. 5. 75.4% of M.D.s and 50.2% of O.M.D.s said that two medical disciplines should be integrated, but they were skeptical on that. 75.3% of M.D.s thought that western hospitals should employ O.M.D.s Finally this study recommended that western medical students study oriental medicine and the vice versa, and M.D.s and O.M.D.s should have seminars and workshops to exchange knowledge, and experiences. It is also recommended that medical laws be revised to allow medical doctors refer the patients whom they can not handle to oriental medical doctors and the vice versa.

  • The purpose of this study was to analyze a causal effect on the housewife's leisure activity participation, leisure expenditure and leisure life satisfaction. Data was collected 249 housewives in Pusan. Data were analysed using descriptive statistics, one-way Anova, multiple regression, Pearson's correlation and path analysis. The main findings of the research were as follows: First, there were significant differences in leisure activity participation according to socio-demographic and economic variables. Physical type showed significant differences when housewife was 30's and unemployed, size of family was 3 and 4, age of the lastborn child was under 6, occupation of husband was professionals and technicians, educational attainment of housewife was under highschool graduate, pattern of housing was collective, income was higher. There were significant differences that occupation of husband was professionals and technicians, educational attainment of housewife was over junior college graduate, pattern of housing was collective, income was higher in self-developing type. restful type showed significant differences when housewife was 40's, age of the lastborn child was under 13-18, educational attainment of housewife was under highschool graduate. There were significant differences that housewife was unemployed in home-oriented type. There were significant differences that housewife was 30's and unemployed, size of family was 4, age of the lastborn child was under 6, occupation of husband was market and sales worker, educational attainment of housewife was over junior college graduate, pattern of housing was collective in time-spending type. Second, there were significant differences in leisure time, leisure expenditure and leisure life satisfaction according to socio-demographic and economic variables. Leisure time showed significant differences when housewife was unemployed, age of the lastborn child was under 13-18, occupation of husband was service, educational attainment of housewife was under highschool graduate, income was higher. Leisure expenditure showed significant differences when housewife was 30's, size of family was under 3, age of the lastborn child was under 6, occupation of husband was senior officials and manager, educational attainment of housewife was over junior college graduate, pattern of housing was collective, income was over 5,000,000 won. There were significant differences that housewife was unemployed in leisure life satisfaction. Third, casual effect was path analysed according to path model. Employment and unemployment of housewife, income and occupation of husband (product & transport equipment operator) had an effect on phycial type.

  • Purpose: The aim of this study was to establish an anthropometric reference of the stomach for gastric cancer surgery and a modeling formula to predict stomach length. Materials and Methods: Data were retrieved for 851 patients who underwent total gastrectomy at the Seoul National University Hospital between 2008 and 2013. Clinicopathological data and measurements from a formalin-fixed specimen were reviewed. The lengths (cm) of the greater curvature (GC) and lesser curvature (LC) were measured. Anthropometric data of the stomach were compared according to age, body weight, height (cm), and body mass index. To predict stomach length, two multiple regression analyses were performed. Results: The mean lengths of the GC and LC were $22.2{\pm}3.1cm$ and $16.3{\pm}2.6cm$, respectively. The men's GC length was significantly greater than the women's ($22.4{\pm}3.1cm$ vs. $21.2{\pm}2.9cm$, P=0.003). Patients aged >70 years showed significantly longer LC than those aged <50 years ($16.9{\pm}2.9cm$ vs. $15.9{\pm}2.4cm$, P=0.002). Patients with body weights >70 kg showed significantly longer GC than those with body weights <55 kg ($23.0{\pm}2.9cm$ vs. $21.4{\pm}3.2cm$, P<0.001). In the predicted models, 4.11% of the GC was accounted for by age and weight; and 4.94% of the LC, by age, sex, height, and weight. Conclusions: Sex, age, height, and body weight were associated with the length of the LC, while sex and body weight were the only factors that were associated with the length of the GC. However, the prediction model was not sufficiently strong.

  • The objective of this study was to investigate the diagnostic significance of EBV antibody combined detection for nasopharyngeal carcinoma (NPC) in a high incidence region of southern China. Two hundred and eleven untreated NPC patients, 203 non-NPC ENT patients, and 210 healthy controls were recruited for the study. The titers of VCA/IgA and EA/IgA were assessed by immunoenzyme assay, and the levels of Rta/IgG and EBNA1/IgA were determined by enzyme-linked immunosorbent assay. The levels of VCA/IgA, EA/IgA, Rta/IgG and EBNA1/IgA demonstrated no association with gender or age (p>0.05). The receiver operating characteristic curve and the area under the curve were used to evaluate the diagnostic value. The sensitivity of VCA/IgA (98.1%) and the specificity of EA/IgA (98.5%) were the highest. When a logistic regression model was used to combine the results from multiple antibodies to increase the accuracy, the combination of VCA/IgA+Rta/IgG, whose area under the curve was 0.99, had the highest diagnostic efficiency, and its sensitivity, specificity and Youden index were 94.8%, 98.0% and 0.93 respectively. The data suggest that the combination of VCA/IgA+Rta/IgG may be most suitable for NPC serodiagnosis.

  • The purpose of this study was to determine the characteristics of infants' temperaments and eating behaviors, mothers' eating behaviors and feeding practices in poor eating infants. The participants were 80 infants of 12-24 months (27 poor eaters and 53 matched normal controls) from a hospital and a public health center. Mothers were questioned about their eating behaviors and feeding practices, and infants' temperaments, eating behaviors, and nutrient intakes by one day food recall. Subjects were divided by mean nutrient adequacy ratio (MAR, < 0.75; poor eater). Intakes of Ca, P, Fe, Zn, thiamin, riboflavin, niacin, vitamin C, E, folate were below 75% RDA in poor eaters, whereas protein, thiamin, riboflavin, vitamin B$_6$, C, folate exceeded 125% RDA in good eaters. Rhythmicity of infants' temperaments and eating behaviors, restriction of mothers' eating behaviors and feeding practices were significantly lower, whereas activity levels of infants' temperaments were higher than good eaters. In multiple logistic regression model of poor eaters, activity of infants' temperaments (T, OR: 1.19, CI: 1.05 - 1.35) and attention spans of infants' eating behaviors (A, OR: 1.18, CI: 1.03 - 1.35) were significantly positive, whereas rhythmicity of infants' eating behaviors (R, OR: 0.79, CI: 0.61-0.94) was significantly negative [E (the legit) : -6.8644+0.1712$\times$T-0.2337$\times$R+0.1641$\times$A]. Our findings suggest that examination of eating behaviors, feeding practices, and temperaments will help target interventions to improve infants' food intakes, and these variables should be examined at the time of nutrition counseling.

  • The purpose of this study was to establish an association between the percent of energy from total sugar and disease prevalence of obesity, hypertension, dyslipidemia, insulin resistance, and metabolic syndrome with the context of the current population dietary practice in Korea. The Korean National Health and Nutrition Survey, 2001 and 2002 dataset were used as the source of data for this research. Usual nutritional intakes for over 20 years old people were calculated from the two non-consecutive dietary intake data from KNHANES 2001 and 2002 dataset. SAS and SUDAAN were used for statistical analyses. Sample weighted means, standard errors, and population percentages were calculated, and multiple logistic regression model with adjustment for covariates were used to determine the odds ratios(ORs) and 95% confidence intervals. Subjects were categorized as 3 ways and compared the LS means and ORs for heath factors. First, subjects excluding pregnant women, were categorized according to percent of energy from the usual total sugar intakes as ${\leq}10%$, 11-15%, 16-20%, 21-25%, >25%. Risk of LDL cholesterol showed a tendency to increase in the '>25%' group compared to the '<10%' group. The risks of the other health effects did not show any significant differences. Second, the subjects were categorized considering both Acceptable Macronutrient Distribution Range(AMDR) from carbohydrate and %Energy from total sugar as 'CHO<55% & Total sugar ${\leq}10%$', 'CHO 55-70% & Total sugar 11-25%', and '$CHO{\geq}70%$ & Total sugar ${\geq}25%$'. The risk of obesity tended to increase in the '$CHO{\geq}70%$ & Total sugar ${\geq}25%$' group compared to the 'CHO<55% & Total sugar ${\leq}10%$'. Third, the subjects were categorized as 'CHO<55% & Total sugar ${\leq}10%$', 'CHO 55-70% & Total sugar 11-20%', and '$CHO{\geq}70%$ & Total sugar ${\geq}20%$'. The risk of obesity also tended to increase in the '$CHO{\geq}70%$ & Total sugar ${\geq}20%$' group compared to the 'CHO<55% & Total sugar ${\geq}20%$' group. In conclusion, risk of LDL cholesterol showed a tendency to increase in the over 25% total sugar intake group, and the risk of obesity tended to increase in the 20-25% total sugar intake and high carbohydrate intake group. The risks of hypertension, hyperlipidemia, insulin resistance, and metabolic syndrome were not associated with total sugar intakes. More research to elucidate the association for Korean between the intakes of total sugar, added sugar, glucose, fructose, and sweeteners and diseases prevalences shoud be excuted in the future.

  • The purpose of this study was to establish an association between glycemic index (GI), glycemic load (GL), dietary carbohydrates and diabetes with the context of the current population dietary practice in Korea. The subjects of 3,389 adults (male 1,430, female 1,959) were divided into normal (serum fasting glucose < 100 mg/dL), impaired glucose tolerance (100 ${\leq}$ serum fasting glucose < 126 mg/dL), diabetes (serum fasting glucose > 126 mg/dL) by serum fasting glucose. Anthropometric and hematologic factors, and nutrient intakes, dietary glycemic index (DGI), dietary glycemic load (DGL) were assessed. Multiple logistic regression model was used to determine the odds ratios (ORs) and 95% confidence intervals for relationship of DGI, DGL, carbohydrates intakes, and diabetes. DGI and DGL were not significantly correlated with impaired glucose tolerance and diabetes. However, the risk of impaired glucose tolerance and diabetes showed a tendency to increase as increase of DGI after multivariate adjustment (age, education, income, region area, diabetes family history, smoking, drinking, exercise, energy intake) in male. The risk of impaired glucose tolerance and diabetes showed a tendency to increase in the DGI 71.1-74.8 after multivariate adjustment in female. DGL was inversely related to impaired glucose tolerance and diabetes in male. In female, however, DGL was positively related to impaired glucose tolerance and diabetes. In particular, the risk of diabetes increased positively in level of DGL 260.5, and remained after multivariate adjustment (Q5 vs Q1:2.38, 0.87-6.48). When percent energy intakes from carbohydrates were more than 70%, the risk of impaired glucose tolerance and diabetes increased in both male and female. In particular, when percent energy intakes from carbohydrates were more than 69.9%, the risk of diabetes increased positively in male (Q4 vs Q1:2.34, 1.16-4.17). In conclusion, above 70% energy intakes from carbohydrates appeared to be a risk factor of diabetes. It seemed that the meal with high GI and GL value must be avoided it. And also, the macronutrients of the meal must be properly balanced. In particular, it may be said that it is a preventive way for treatment of the diabetes to avoid eating carbohydrates of much quantity.
