  • 1. Objectives There are many studies on the ordinary symptoms based on Sasang constitution. But there. are not quite satisfactory between the types of Sasang constitution. So This study is for learning the characteristics of ordinary symptoms depending on Soyangin Soeumin and Taeyangin Taeumin of the Sasang constitution. 2. Methods One thousand and two hundred twenty nine subjects were included in Bundang Oriental Hospital of Dongguk University. We classified them into the each type of Sasang Constitutional Medicine(SCM) by the well-trained SCM specialist, and assessed their ordinary features by the questionnaire. Binary logistic regression analysis was applied to evaluate the influence of ordinary features to the diagnosis of SCM. 3. Results (1) Compared to Taeyangin Taeumin, Soyangin Soeumin do not sweat a lot. Even if Soyangin Soeumifl do sweat, one does not feel refreshed. Soyangin Soeumin do not sweat while sleeping at night nor eating meals, but discharges cold sweat if one does not feel well. (2) Compared to Taeyangin Taeumin, Soyangin Soeumin go to stool less frequently and have diarrhea when one does not feel well. Soyangin Soeumin do not feel irritated even though one is not able to go to stool for one day. (3) Compared to Taeyangin Taeumin, Soyangin Soeumin do not have foams in urine. (4) Compared to Taeyangin Taeumin, Soyangin Soeumin tend to eat slow, do not eat a lot normally, do not have a great appetite, have problems for digestion, and especially have difficulties in digestion when one is stressed. 4. Conclusions We found that Taeyangin Taeumin and Soyangin Soeumin have characteristics of ordinary symptoms, but partly there are not in accoradance with ones what Lee ]e-Ma said in his book. So in future we hope clinical studies are required steadily.

  • Background: To investigate whether CT findings can predict the invasiveness of persistent cancerous pure ground glass opacity (pGGO) by correlating the CT imaging features of persistent pGGO with pathological changes. Materials and Methods: Ninety five patients with persistent pGGOs were included. Three radiologists evaluated the morphologic features of these pGGOs at high resolution CT (HRCT). Binary logistic regression was used to assess the association between CT findings and histopathological classification (pre-invasive and invasive groups). Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of diameters. Results: A total of 105 pGGOs were identified. Between pre-invasive (atypical adenomatous hyperplasia, AAH, and adenocarcinoma in situ, AIS) and invasive group (minimally invasive adenocarcinoma, MIA and invasive lung adenocarcinomas, ILA), there were significant differences in diameter, spiculation and vessel dilatation (p<0.05). No difference was found in air-bronchogram, bubble-lucency, lobulated-margin, pleural indentation or vascular convergence (p>0.05). The optimal threshold value of the diameters to predict the invasiveness of pGGO was 12.50mm. Conclusions: HRCT features can predict the invasiveness of persistent pGGO. The pGGO with a diameter more than 12.50mm, presences of spiculation and vessel dilatation are important factors to differentiate invasive adenocarcinoma from pre-invasive cancerous lesions.

  • Purpose: This study was considered in order to identify the factors affecting healthcare utilization by Asian immigrants in the United States. Methods: From February to April 2011, a descriptive survey study was conducted in a convenience sample of 250 Korean and Asian Indian immigrants aged between 40 and 64 in the Triangle area of North Carolina. An author-developed instrument was used to assess predisposing, enabling, and need factors according to Anderson's Behavioral Model of Health Services. Utilization Data analysis was performed by $X^2$-test, t-test, and binary logistic regression. Results: Participants' healthcare services experiences were significantly different when they had a longer stay in the U.S., had been employed, had higher income, were Asian Indians, had better English-speaking skills, better health status, more knowledge of health system and health insurance, had higher satisfaction with the healthcare system, and when they were taking prescribed medications and having health insurance. The strongest association with experience of healthcare services was having health insurance with an adjusted odds ratio (OR) of 15.37 (95% CI 4.95-47.71, p<.001) and self-reported English proficiency (OR=1.99, 95% CI 1.00-3.96, p=.05). Conclusion: Intervention strategies to increase accessibility to healthcare services should focus on these significant predictors.

  • The objective of this study was to measure anthropometric and haemoglobin level and nutrient intake of expecting women in the third trimester of pregnancy and to relate the birth weight of neonates as outcome of pregnancy. A cross sectional study was performed in Zahedan City. Two hospitals situated in the city were selected based on their approval and cooperation. Five hundred healthy pregnant women in the age group 16-40 years were selected for this study. Findings showed that the mean height, weight, fundal height, and haemoglobin of pregnant women were 156.4 cm, 62.6 kg, 34.2 cm, and 11.1g/dl respectively. Nutrient intake was computed based on 24 hour recall method. The results showed that, the mean intake of energy was 1802 Kcal/day. The intake of protein, calcium, iron, zinc and magnesium were 70.7 g, 544.0 mg, 16.1 mg, 10.6 mg and 266.0 mg respectively. Percentage adequacy of nutrient intakes with reference to RDA recommendation showed 95% and 80% of subjects had sufficient RDA intakes, while energy, calcium, iron and zinc intake considered as insufficient. The mean birth weight of neonates was 3.0 kg and 13% of neonates showed low birth weight. Maternal height, weight, fundal height and haemoglobin level were significantly correlated with birth weight of neonates. Energy, protein and calcium intakes in the third trimester were significantly correlated with birth weight of neonates. Using the binary logistic regression analysis fundal height, haemoglobin level and energy intake of pregnant women were considered as predictor factors of birth weight of neonates.

  • Objective : Stroke is one of the most common causes of death in Korea. This study was done to evaluate the association of complete blood count (CBC) with the risk of hemorrhagic stroke and ischemic stroke. Methods : In 217-case patients with ischemic stroke or hemorrhagic stroke and 146 healthy control subjects without stroke, hypertension, diabetes mellitus, hyperlipidemia, or ischemic heart disease and 160 controls without ischemic stroke or hemorrhagic stroke, we tested and compared white blood cell count (WBC), red blood cell count (RBC), hemoglobin (Hgb), hematocrit (Hct) and platelet. These data were statically analyzed by general linear models and binary logistic regression analysis to get each adjusted odds ratio. Results :The level of WBC was significantly higher in all cases. The level of RBC, Hct and Hgb was significantly lower in patients of ischemic stroke. The level of platelet was significantly higher in patients of ischemic stroke. Conclusion : These results suggest high WBC may be a risk factor of hemorrhagic stroke and ischemic stroke and low RBC, low Hct, low Hgb and high platelet may be risk factors of ischemic stroke in Koreans.

  • Objective : To evaluate the risk factors that may be responsible for the development of contralateral reherniations from ipsilateral ones after open lumbar microdiscectomy (OLM), and to compare surgical outcomes of revision OLM for contralateral reherniations with those for ipsilateral ones. Methods: Seventeen patients who underwent revision OLM for contralateral reherniation were enrolled into Group I, and 35 patients who underwent revision OLM for ipsilateral reherniation were enrolled into Group II. Using medical charts and imaging study results, the differences in the clinical and radiological factors were evaluated between the two groups. Clinical outcomes of each group were compared between the two groups. Results: Significant differences were found in the interval to reherniation from initial surgery (33 months for Group I and 18.6 months for Group II, p=0.009), as well as in the incidences of both protruded disc (35.3% for Group I and 8.6% for Group II, p=0.045) and mild disc degeneration (29.4% for Group I and 5.7% for Group II, p=0.031) at initial surgery. On binary multi-logistic regression analysis, significant differences were found in the interval to reherniation (p=0.027, Odds ratio=1.051) and incidence of mild disc degeneration (p=0.025, Odds ratio= 12.03) between the two groups. There were no significant differences in the improvement of clinical outcomes after revision OLM between the two groups. Conclusion: The interval to reherniation from initial surgery and the grade of disc degeneration at initial surgery were key factors that distinguished the development of contralateral reherniations from ipsilateral ones. Surgical outcomes of revision OLM were similar in both groups.

  • Objectives: This study is a descriptive research study conducted to grasp the Prediction factors of the sexual violence experience of college students. Methods: A convenience sampling was performed for 500 students from one college located in Gyeongsangbuk-do, who agreed to the purpose of this study. Data collection was conducted from October 5, 2015, to October 23, 2015, by filling out the self-report questionnaire. Among the 450 subjects excluding those with missing values, a questionnaire of dating violence experience was applied to 317 college students who answered that they had a friend of the opposite sex, and variables and prediction factors related to dating violence experiences were identified. The statistical methods used were descriptive statistics, x2-test, t-test, Pearson's correlation coefficient and binary logistic regression analysis. Results: As a result of the study, the experience of sexual behavior before entering college (𝑥2=6.52, p=.011), experience of sexual violence damage before entering college(p=.045), the experience of sexual assault before entering college (p=.007) and experience of school violence damage(p=.002) were variables related to the sexual violence experience of college students. School violence victimization (OR=4.831, p=.007) and controlling dating partners (OR=1.349, p<.001) were predictors of dating sexual violence. Dating sexual violence experience group were compared to dating sexual violence non-experience group, the relative degree of controlling dating partners was high (t=4.25, p<.001) and had a traditional gender role attitude (t=2.94, p=.004). and there was a positive correlation (r=.358, p<.001) between controlling dating partners and gender role attitude. Conclusions: In order to prevent sexual violence on dating among college students, it is expected that more effective health education results will emerge if the contents of the school-age school violence victimization experience and the control of dating partners, which are predicted factors of sexual violence on dating, are included in the sexual violence prevention program.

  • Purpose: The purpose of this study was to analyze the effect of sexual attitude among the elderly to their sexual life while exploring the moderating effect of general characteristics in the relationship between sexual attitude and sexual life. Methods: A descriptive research design was used. The subjects were 322 married elderly from four silver centers in Seoul and Gangwon-do. Aging Sexuality Attitude Scale developed by White (1982) was used to examine sexual life status and general characteristics of the subjects (gender, age, academic background, religion, economic status, and residential type). For data analysis, ${\chi}^2$-test, t-test, and ANOVA were conducted. Since the dependent variable of sexual life is a binary variable, hierarchical logistic regression was implemented. Results: There were 180 people (55.9%) who had a sexual life. Depending on gender (${\chi}^2$=35.03, p<.001), academic background (${\chi}^2$=29.45, p<.001), and economic status (${\chi}^2$=7.36, p=.025), the subjects showed significant difference in terms of sexual life. Regarding sexual attitude, the subjects showed significant difference depending on gender (t=-5.47, p<.001), age (t=-2.31, p=.021), academic background (t=5.16, p<.001), economic status (F=3.17, p=.043), and sexual life status (t=4.99, p<.001). Conclusion: It is important to devise the sex education program in consideration of gender, age, and academic background that showed moderating effects.

  • This study analyzes important urban characteristics according to location of large-scaled professional sports facilities based on a binary logistic regression model and t-test. For the empirical analysis, this study uses 24 urban characteristics within social, economic, cultural, traffic, and spatial categories in 228 cities. The results show that economic condition can be the main decision factor for the differential feature of the location as well as social and traffic conditions. Concretely, more the number of young adults and middle-aged people who have considerable purchasing power, and available land are more the beneficial to the presence of the sports facilities. Recently local governments focus on location of the facilities due to their impacts on regional economics as well as residents' quality of life. In this point of vies, this study gives good understanding why it is a great option for location of the facilities.

  • This study examines the impact of sleep duration on Korean adolescents' suicidal impulse. A gender-based analysis was conducted using binary logistic regression method. The major findings are as follows. First, weekday sleep duration had a significant effect only on male adolescents. Male adolescents who sleep less than seven hours on a weekday are likely to experience suicidal impulse by 1.9 times higher than the others. This effect remained significant even when other relevant variables were controlled. On the other hand, female adolescents who have less than seven hours of sleep on a weekday have about 1.3 times higher chances to experience suicidal impulse. However, this effect became insignificant when other variables such as stress were controlled. Meanwhile, weekend sleep duration did not have any significant effect on both male and female adolescents. By demonstrating the different effects between weekday/weekend sleep duration and male/female adolescents, this study supports the claim that it is necessary to take a social approach in studying sleep duration.
