The prevalence of diabetes continues to increase worldwide, and the problem is also important in Korea, and about 14% of Korean adults have diabetes. Alcohol consumptions are increasing rapidly around the world and are recognized as one of the major problems in the country. Alcohol consumption is an environmental factor previously known to be associated with the risk of developing diabetes. Alcohol consumption can cause problems in the endocrine system and gastrointestinal function, and oxidative stress of acetaldehyde, an ethanol metabolite, can damage beta cells in the pancreas. In the present study, we found the effect of alcohol intake on fasting blood sugar and the difference between men and women in the risk of diabetes according to alcohol intake. In men, the high-drinking group had a higher risk of diabetes than the non-drinking group (OR, 1.41; P=0.058). In women, the Moderate-drinking group had a lower risk of diabetes compared to the non-drinking group (OR, 0.42; P=0.039). The high-drinking group had a higher risk of diabetes than the non-drinking group (OR, 2.97; P=0.034). The group that consumed more than the WHO's daily alcohol intake risk standard tended to have a higher risk of diabetes than the group that did not (OR, 5.48; P=0.001). This study suggest that moderate alcohol consumption reduce the risk of developing diabetes, and high alcohol consumption increase the risk of developing diabetes.

Objective: To compare neonatal respiratory morbidity of twins according to birth order related to gestational age and mode of delivery. Methods: We performed the retrospective research of the medical records of 3,224 neonates (1,612 twin pairs) born in a single center from January 2011 to December 2015. Subjects were classified into four gestational age groups: very (<32 weeks), moderate (32-33 weeks), late (34-36 weeks) preterm, and term (${\geq}37weeks$) groups. We investigated clinical characteristics and respiratory morbidity according to birth order related to gestational age group and mode of delivery. Results: We found increased risk of respiratory morbidity in second-born twin than first-born twin (P=0.039). Second-born twin was associated with increased risk of respiratory distress syndrome (RDS) in late preterm group (odds ratio [OR] 2.8, 95% confidence interval [CI] 1.30-5.95), and transient tachypnea of newborn in term group (OR 1.4, 95% CI 1.03-1.81). In vaginal delivery mode, there was no difference of respiratory morbidity between first and second-born twin in each group, but in cases of Cesarean delivery, second-born twin was related with a greater risk of RDS in late preterm group (OR 2.3, 95% CI 1.07-5.09). Birth order and Cesarean section independently increased the risk of RDS (adjusted OR [aOR] 1.69, 95% CI 1.12-2.54; aOR 2.14, 95% CI 1.25-3.66, respectively). Conclusion: Second-born twin and Cesarean delivery are associated with increased risk of RDS, especially in late preterm twins.

Objectives : The objective of this study is to assess the prevalence and risk factors of metabolic syndrome (MS) among inpatients with schizophrenia, and to compare with general population. Methods : Nine hundreds seventy inpatients were included to assess the prevalence of MS from two mental hospitals in Yong-in city. Assessment of MS was performed based on modified American Heart Association criteria with abdominal obesity threshold of 90cm for men, 85cm for women. Comparative analysis was performed using age- and gender matched sample from Korea Health and Nutritional Examination Survey III. For evaluating risk factors, analysis included 766 inpatients taking consistent medications at least for 30 days. Results : The prevalence of MS of inpatients with schizophrenia was 26.2%, in females it was 33.2%, compared to 20.2% in males(p < 0.001). Compared to general population, the prevalence of MS was significantly lower in male and higher in female patients. In terms of criteria prevalence, who met abdominal circumference criterion were more prevalent in patient group(p < 0.001). After multivariate analysis, female gender and old age remained as risk factors of MS. Conclusions : The prevalence of MS of inpatients with schizophrenia was 26.2% and significantly low compared to general population. Female gender and old age were risk factors of MS.

Objectives : Epidemiological studies in other countries show that a low intake of omega-3 fatty acids (FAs) increases the risk of depression or suicidality. However, no studies have investigated the associations of suicidality with omega-3 FAs in Korea. Hence, this cross-sectional study aimed to investigate the effects of omega FAs on suicidality in the general South Korean population. Methods : The data in this study were sourced from adults (n=215,860) who completed the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI), and the associations between omega FAs and suicidality were analyzed using multivariate logistic regressions. Results : Our results demonstrated that high omega-3 FA intake was associated with a decreased risk of suicide (OR=0.83, 95% CI : 0.71-0.98) and the high omega-6 to omega-3 FA ratio was associated with an increased risk of suicide (OR=1.25, 95% CI : 1.02-1.54). Additionally, a high intake of omega-3 FAs was associated with a decreased risk of suicide in men, but not in women (OR=0.72, 95% CI : 0.59-0.88). Conclusions : Overall, our findings suggest that a lower intake of omega-3 FA is associated with the increased risk of suicidality in the general Korean population, especially in men.

Purpose: The purpose of this study was to investigate the present status of falls among inpatients in general hospitals and to identify the fall risk factors that reflect the characteristics of domestic hospitals. Methods: Data were collected between December 15, 2016 and January 15, 2017 from 32 Korean hospitals having 500 or more beds. First, 42 risk factors were extracted based on literature review and expert opinions. Then the importance of each factor was evaluated by 223 nurses from medical and surgical adult ward and intensive care units in 40 hospitals. Results: The incidence rate of falls in 18 hospitals was 3.87 per 1,000 total discharged patients and 0.55 per 1,000 patient-days, and the rate of injury-related falls was 40.5%. Major risk factors for falling were identified as the following: being over 65 years of age, history of falls during admission, physical mobility disorders requiring assistance, physical factors (dizziness or vertigo, unstable gait, general weakness, walking aids, visual problems), cognitive factors (delirium, lack of understanding on limitations), neurological disease, CNS medications Conclusion: The findings provide information that can be in the development of a fall risk assessment tool for inpatients in general hospitals in Korea.

Purpose: Surgical Site Infection(SSI) is the third most common cause of nosocomial infection, so that it results in serious socioeconomic impact such as extra hospitalization, mortality and health care cost. The aim of this study was to analyses the SSI that based on the degree of wound contamination and patient risk index after general surgery and to generate a reference data for the effective management and reducing SSI. Method: From July, 1999 to June, 2000, 1080 cases which presented with surgical site infection after general surgery at S hospital in chunchon city were included in this study. The data were collected by review of the medical records retrospectively. The collected data, in accordance with the test purpose, is analyzed by SPSS/PC+ program, using real numbers, percentage, $X^2$ test, Pearson's correlation and stepwise logistic regression. Result: The overall wound infection rate was 4.7%(51 cases out of 1,080). The infection rate of clean wounds was 1.4%. Surgical site infection rate for patient risk index scores of 0, 1, 2 and 3 was 1.9%, 8.0%, 13.1% and 20.0%, respectively and increased significantly according to patient risk index(p=.000). Sixteen of the fifty one(31.4%) surgical site infections were found during an outpatient visit after discharge. Multivariate analysis, identified two independent variables : duration of postoperation stay(p=.000), age(p=.037). The most frequent isolated organisms were Pseudomonas aeruginosa(21%) and Staphylococcus aureus(21%). Also Staphylococcus aureus were all MRSA(Methicillin Resistant S. aureus). Conclusion: In this study, SSI was analysed according to the degree of wound contamination and patient risk index after general surgery. The data that obtained from this study is expected that it would be available for surveillance and control of SSI.

There have been various studies on measurements of flood risk and forecasting models. For river and dam region, PDF and FVI has been proposed for measurement of flood risk and regression models have been applied for forecasting model. For Bo region unlikely river or dam region, flood risk would unexpectedly increase due to outgoing water to keep water amount under the designated risk level even the drain system could hardly manage the water amount. GFI and general linear model was proposed for flood risk measurement and forecasting model. In this paper, FVI with the consideration of duration on GFI was proposed for flood risk measurement at Bo region. General linear model was applied to the empirical data from Bo region of Nadong river to derive the forecasting model of FVI at three different values of Base High Level, 2m, 2.5m and 3m. The significant predictor variables on the target variable, FVI were as follows: ground water level based on sea level with negative effect, difference between ground altitude of ground water and river level with negative effect, and difference between ground water level and river level after Bo water being filled with positive sign for quantitative variables. And for qualitative variable, effective soil depth and ground soil type were significant for FVI.
