Inferior sinus venosus defect is a rare lesion in which there is a large interatrial communication adjacent to the atrial connection of the inferior caval vein. The defect is located posteriorly and inferiorly, outside the confines of the true atrial septum, and partial anomalous pulmonary venous connections are the rule. We underwent surgical repair in four patients with inferior sinus venosus defect and partial anomalous pulmonary venous return. There were three males and one female with an age range from four months to 25 years. A cross- sectional echocardiogram and cardiac catheterization had been performed preoperatively in all patients, but the correct diagnosis had been made in only one case. Surgical repair was indicated due to congestive heart failure, and one patient of 4-month-old needed urgent operation. The repair was accomplished by suturing a untreated autologous pericardial patch to the right of the pulmonary veins, so that the defect was closed and all the pulmonary venous blood was directed to the left atrium. The preoperative knowledge of the unusual anatomy allows the surgeon to repair the anomaly without difficulties. For the patients in whom interatrial communication and anomalous pulmonary venous return are suggested, surgeon has to pay careful attention to the anatomical landmarks to avoid incorrect placement of the patch.

Background: Risk assessment for pulmonary resection in patients with early-stage non-small-cell lung cancer (NSCLC) is important for minimizing postoperative morbidity. Depletion of skeletal muscle mass is closely associated with impaired nutritional status and limited physical ability. We evaluated the relationship between skeletal muscle depletion and early postoperative complications in patients with early-stage NSCLC. Methods: Patients who underwent curative lung resection between 2016 and 2018 and who were diagnosed with pathological stage I/II NSCLC were included, and their records were retrospectively analyzed. The psoas volume index (PVI, ㎤/㎥) was calculated based on computed tomography images from routine preoperative positron emission tomography-computed tomography. Early postoperative complications, defined as those occurring within 90 days of surgery, were compared between the lowest sex-specific quartile for PVI and the remaining quartiles. Results: A strong correlation was found between the volume and the cross-sectional area of the psoas muscle (R²=0.816). The overall rate of complications was 57.6% among patients with a low PVI and 32.8% among those with a normal-to-high PVI. The most common complication was prolonged air leak (low PVI, 16.9%; normal-to-high PVI, 9.6%), followed by pneumonia (low PVI, 13.6%; normal-to-high PVI, 7.9%) and recurrent pleural effusion (low PVI, 11.9%; normal-to-high PVI, 6.8%). The predictors of overall complications were low PVI (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.07-4.09; p=0.03), low hemoglobin level (OR, 0.686; 95% CI, 0.54-0.87; p=0.002), and smoking history (OR, 3.93; 95% CI, 2.03-7.58; p<0.001). Conclusion: Low PVI was associated with a higher rate of early postoperative complications in patients with early-stage NSCLC.

This study was performed to investigate elementary school children's awareness on children's favorite foods and their consumption behavior of the foods. This study also focused on the association between the variables and gender/grade. We conducted a cross-sectional survey with direct interview among three hundreds and six elementary school children (188 boys and 118 girls) from 13 schools of a city of Korea, using a structured questionnaire. Among the overall proportion, more than 20% of the respondents did not know children's favorite foods and/or have no information source on the foods. More than 60% of the respondents consumed children's favorite foods more than 1 to 2 times a week. Only 16% respondents got information on children's favorite foods at home and 37% at school. There were significant correlations (p < 0.05) between gender/grades and knowledge/route of information on children's favorite foods. Boys had more knowledge than girls (p < 0.05), however they showed worse attitude on children's favorite foods and consumed more the foods. The higher grade children had more knowledge, better attitude and various routes of information on children's favorite foods (p < 0.05), but consumed more the foods. The results of this study indicate that there is a discrepancy between knowledge and attitude/behavior. This study also indicate that school food-service program and food hygiene/safety education in school and at home should be improved. Strong implementation of laws for regulation of selling adulterated food around elementary school may be another step in controlling consumption of the food by school children.

Parental smoking status and smoking environment do not only affect children's health through exposure to nicotine, but are also related to children's smoking attitude, intention and knowledge of smoking. Since this study was conducted to examine a relationship between family members smoking and smoking attitude, intention and knowledge of their children, little is known about psychosocial factors influencing smoking among Korean preschool children. This study aimed to determine the psychosocial factors (sociodemographic factors, education for smoking cigarette, knowledge about smoke cigarette) influencing smoking attitude and smoking intention, with a purpose of providing directions for future education programs for Korean preschool children. A cross sectional sample of 840 children, ages 4-7 years, living in a rural district were interviewed during August 6 - November 14, 2003. Among them, 834 children whose missing data were less than $10\%$ were included the analysis. The independent variables included sociodemographic characteristics and education for smoking cigarette, while the dependent variables were knowledge about smoking, the children's smoking attitude and their intention of smoking. The data on sociodemographic characteristics were analyzed using descriptive statistics including frequency, percentage, mean, and standard deviation. The correlations between the independent variables and attitude and intention of smoking were analyzed using chi-square test, t-test, and logistic regression. The results of this study were s follows. The factors that were found to be significantly correlated to smoking attitude include mother's smoking $(x^2=4.86,\;p=.03)$, grandmother's smoking $(x^2=5.56,\;p=.02)$, and knowledge of smoking cigarette $(x^2=-5.13 p<.01)$. The factors that were significantly correlated to the intention of smoking include gender $(x^2=.08,\; p=.02)$, education for smoking$(x^2=17.65,\;p<.01)$, mother's smoking $(x^2=19.05,\; p<.01)$, grandmother's smoking $(x^2=17.67,\; p<.01)$, and knowledge$(x^2=-2.17,\;p=.03)$. The children who had non smoking mother were more likely to have negative attitude (OR=2.29). The children who had a higher knowledge about smoking were more likely to have negative attitude (OR=1.58). The findings suggest that a smoking prevention program specific for preschool children is necessary to prevent early onset of smoking. The findings also suggest that the program should involve children's family members who influence their smoking attitude and intention.

Purpose: This study was conducted in order to examine the level of physical activity and influencing factors in female college students. Method: Cross-sectional survey data including physical activity, exercise self-efficacy, social influences on physical activity, and perceived health status were collected from 213 subjects. Data from 204 subjects were analyzed. Results: The mean level of physical activity was 2,750.97 MET-min/week. Physical activity showed a positive association with exercise self-efficacy as well as social influences, and a negative association with age. Stepwise multiple regressions showed that physical activity among female college students was predicted by type of leisure activity, relative health status, social influences, and age. Conclusion: The findings suggest that a program for improvement of physical activity in female college students should include interesting and dynamic leisure activities and strategies for performing together with friends should be developed.

This study was a cross-sectional descriptive study of the effects of emotional happiness on aging preparation for 45-60 year olds. Participants of this study were 312 volunteers and data was collected online, the collection period was from May 15, 2018 to May 31, 2018. The tools used in the research were the emotional happiness developed by Watson et al (1988) et al., the aging preparation developed by JH Lee (2009). Analysis was done using t-test, ANOVA, Pearson correlation, and regression by SPSS 18.0. As a result of the analysis, 84.0% of participants felt physically healthy and 89.8% felt mental health. The spouses of participants were physically 83.4% healthy and mentally 82.7% healthy. The correlation between emotional happiness, health cognition and aging preparation showed that physical health had a correlation with mental health (r = .482, p <0.01) and emotional happiness (r = .369, p <0.01), economic aging preparation (r = .411, p <0.01), social aging preparation (r = .119, p <0.01). Mental health was correlated with emotional happiness (r = .491, p <0.01), economic aging preparation (r = .411, p <0.01) and social aging preparation. Difference between emotional happiness and retirement preparation according to presence or absence of disease, emotional happiness (t = -4.503, p <0.01) and economic aging preparation (t = -4.960, p <0.01) were statistically significant. Emotional happiness affects the preparation of old age, emotional happiness affects to physical aging preparation under statistical significance (F=25.191, p<0.01), economic aging preparation (F=1131.783, p<0.01), and social aging preparation (F=147.672, p<0.01) which were sub components of aging preparation. Emotional happiness showed a 7.5% effect on the preparation of physical aging, 78.4% on economic aging preparation and 32.3% on social aging preparation. Based on the above results, it can be concluded that physical health and mental health are related to emotional happiness, economic aging preparation, and social aging preparation. And also these results can be inferred that the illness causes emotional less feeling of happiness and economic difficulty. Based on the results of this study, emotional well - being influences the retirement preparation significantly at statistical significance. Therefore, if the concept of emotional happiness is introduced to the old-age preparation program, it will be more client centered program.

Purpose : This study was done to identify the factors of decisional balance for smoking cessation among middle aged men in Korea. This was composed of a set of variables at the level of decision making when middle aged men decide to stop smoking. It was used to classify and identify the characteristics of the stages of change for smoking cessation to which the middle aged men belong, and was used to identify the variables of decisional balance which influenced the stages of change for smoking cessation in middle aged men. Methods : A convenience sample of 169 men who had smoked and were smoking, were between age 30 and 60 and lived in Seoul(mean age=44), were selected from the community. The data was collected from December 10, 1999 to February 28, 2000. The research instrument was the Decisional Balance Measure for Smoking Cessation (Velicer et al., 1985). and Stage of Change Measure(DiClemente et al., 1991). The data were analyzed using the SAS Program. Results : 1. According to stage of change measure, the 169 subjects were distributed in each stage of change for smoking cessation: in the pre-contemplation stage 63 subjects(32.7%), contemplation stage 60 subjects (35.5%), preparation stage 17 subjects(10.1%), and maintenance stage 29 subjects(17.2%). 2. Factor analysis identified 4 factors of decisional balance as appropriate factors for smoking cessation of middle aged men. There were named by the researchers; 1)'Perceived Burden to Self', 2)'Perceived Benefit to Others' 3)'Perceived Approval to Others', and 4)'Perceived Disapproval to Self'. 3. Analysis of variance showed that the three components, 1)'Perceived Burden to Self(F=8.50, P=.0001)', 2)'Perceived Benefit to Others(F=3.19, P=.025)' and 3)'Perceived DisApproval to Self(F=2.87, P=.038)were significantly associated with stage of change. 4. Through discriminant analysis, it was found that 'Perceived Burden to self' was the most influential variable in discriminating the four stages of change(pre-contemplation, contemplation, preparation, and maintenance). Conclusion : The results are consistent with the application of the Transtheoretical model, which has been used to understand how people change health behavior. Even though this study is a cross-sectional, not a longitudinal study, the findings of this study give useful information for smoking cessation intervention for the middle aged men.

The high unemployment rate is one of the major problems in most countries nowadays. Hence, the demand for small area labor statistics has rapidly increased over the past few years. However, since sample surveys for producing official statistics are mainly designed for large areas, it is difficult to produce reliable statistics at the small area level due to small sample sizes. Most of existing studies about the small area estimation are related with the estimation of parameters based on cross-sectional data. By the way, since many official statistics are repeatedly collected at a regular interval of time, for instance, monthly, quarterly, or yearly, we need an alternative model which can handle this type of panel data. In this paper, we derive the generalized kernel estimating equation which can model time-dependency among response variables and handle repeated measurement or panel data. We compare the proposed estimating equation with the generalized linear model and the generalized estimating equation through simulation, and apply it to estimating the unemployment rates of 25 areas in Gyeongsangnam-do and Ulsan for 2005.

In this paper, we develop the high-risk drinking predictive model in Korea using the cross-sectional data from Korea Community Health Survey (2014). We perform the logistic regression analysis, the decision tree analysis, and the neural network analysis using the data mining technique. The results of logistic regression analysis showed that men in their forties had a high risk and the risk of office workers and sales workers were high. Especially, current smokers had higher risk of high-risk drinking. Neural network analysis and logistic regression were the most significant in terms of AUROC (area under a receiver operation characteristic curve) among the three models. The high-risk drinking predictive model developed in this study and the selection method of the high-risk intensive drinking group can be the basis for providing more effective health care services such as hazardous drinking prevention education, and improvement of drinking program.
