PURPOSE: The purpose of this study was to investigate the level and factors influencing depression among nursing students. METHODS: The data were collected from nursing students attending 3 universities who expressed a willingness to participate in the study through a questionnaire which surveyed them about depression, stress, social support, self-efficacy, self-esteem, and wellbeing in May, 2012. The collected data from 235 nursing students were analyzed using a SPSSWIN 19.0. RESULTS: The mean score of depression (using MDI) among nursing students was 16.7, which denotes a minor depressive mood. 49.1% of variance with regard to depression among nursing students was explained by stress, self-esteem, wellbeing and self-efficacy. CONCLUSION: There is a need to develop a depression prevention program for nursing students and to reduce stress and increase self-esteem, wellbeing and self-efficacy in order to establish an effective program.

PURPOSE: The purpose of this study was to analyze the history of exposure to obscene material, and examine sexual attitudes and intercourse experience in order to develop an effective program for university students. METHOD: The data were collected in May, 2012 from 385 students attending 3 universities in Korea. An independent t-test and ANOVA were used to determine the differences with regard to sexual attitudes and intercourse experience according to general characteristics and history of exposure to obscene material. RESULTS: Sexual attitudes significantly differed according to timing of first exposure to obscene material (p<.001). Intercourse experience was significantly different according to timing of first exposure to obscene material (p=.016) and type of exposure to obscene material (p=.032). There was a negative correlation between first exposure to obscene material and sexual attitudes (p<.001), and a positive correlation between first exposure to obscene material and intercourse experience (p=.017). CONCLUSION: Results of this study indicate that history of exposure to obscene material should be considered as an important variable in managing the sexual health of university students.

PURPOSE: To compare the clinical characteristics and laboratory finding between adenoviral and group A streptococcal (GAS) pharyngitis. METHODS: A retrospective review of medical records was performed in the patients with adenovirus infection among those who were admitted for febrile respiratory disease from January 2011 to July 2013 and GAS pharyngitis among those who visited for symptoms of scarlet fever from August 2006 to July 2013. RESULTS: 179 patients (AV1 group) were diagnosed with adenoviral pharyngitis and 37 (AV2 group) of these patients had adenovirus single infection. 26 patients (GAS group) were diagnosed with scarlet fever. Adenoviral infection (AV2 group) developed in younger patients compared to GAS group (2.8+/-2.1 years vs. 5.4+/-1.8 years, P=0.000). Total durations of fever and admission were longer in AV2 (6.3+/-2.6 days vs. 3.3+/-1.9 days, P=0.000; 4.1+/-1.2 days vs. 1.9+/-1.8 days, P=0.000, respectively). WBC counts were higher in AV2 (11,449+/-5,680 cells/mm2 vs. 6,722+/-6,941 cells/mm2, P=0.000). CRP was not significantly different between AV2 and GAS group (3.8+/-3.2 mg/dL vs. 5.2+/-5.1 mg/dL, P=0.368). No difference was found between two groups in the percentage of antibiotics use (91.9% vs. 100%, P=0.261). CONCLUSION: Clinical characteristics and measures of inflammation in the laboratory findings were similar between adenoviral and GAS pharyngitis group. It is necessary to conduct the test for respiratory virus and bacteria in early stage to differentiate in the pharyngitis patients with leukocytosis and elevation of CRP level.

Objectives: ：The purpose of this study was to identify suicide risk factors among elderly residents in Gyeongsangbuk-do and to reveal the relationships between them. In addition, the differences in suicide risk factors were analyzed between the cognitively impaired group and the cognitively normal group. Methods: ：We investigated 20,127 elderly over 65 years of age, from January 2019 to December 2019. Participants were asked to complete a questionnaire survey. Cognitive function, depression, anxiety, sleep disturbance, and suicidal ideation data were assessed using a Korean version of the Mini-Mental Status Examination for Dementia Screening (MMSE-DS), Short Geriatric Depression Scale for Korean version (S-GDS), Geriatric Anxiety Inventory (GAI), Athens Insomnia Scale (AIS), and Scale for Suicidal Ideation (SSI). Data were analyzed using the chi-squared test and logistic regression analysis to examine suicide risk factors and the relationships between them. Furthermore, differences in suicide risk factors according to cognitive function were examined. Results: ：Age, cognitive function, depression, anxiety, and sleep disturbance were identified as suicide risk factors among elderly residents in Gyeongsangbuk-do. Depression was the factor that increased risk of suicide the most, followed by anxiety, impaired cognitive function, sleep disturbance, and 65-74 years of age. In addition, depression increased risk of suicide by 1.86 times in the cognitively impaired group. Conclusions ：Among elderly residents in Gyeongsangbuk-do, depression was the factor that contributed the highest risk for suicide. More active prevention and treatment measures for depressive symptoms should be implemented in the cognitively impaired group.

PURPOSE: Meconium aspiration syndrome (MAS), often progresses to respiratory failure and its' serious complication, persistent pulmonary hypertension of the newborn (PPHN) is a major cause of neonatal mortality. Early recognition of infants at the risk for respiratory failure in MAS patients is necessary for treatment. So we aimed to identify serum enzymes such as lactate dehydrogenase (LDH), aspartate transaminase (AST), and alanine transaminase (ALT) as serum biologic marker for early detection of respiratory failure in MAS patients. METHODS: Infants admitted within 24 hours after birth to Neonatal Intensive Care Unit of Dongguk University Ilsan Hospital and diagnosed with MAS from August 2005 to March 2014 were analyzed retrospectively. Serum enzymes were measured on admission. RESULTS: Of the total 60 patients diagnosed with MAS, 28 were in the positive pressure ventilation (PPV) group and 32 were in the non-PPV group. Six patients progressed to PPHN. Only serum LDH was significantly higher in the PPV group than the non-PPV group (median 1,123 vs. 831, P =0.01). Using the ROC curves, the cut-off value of 964 U/L for LDH offered the best predictive value for PPV requirement (sensitivity 61% and specificity 81%). Serum LDH was significantly higher in MAS with PPHN group than MAS without PPHN group (median 1,791 vs. 904, P =0.013). But serum AST, ALT were not predicting factor for the requirement of respiratory support and development of PPHN among MAS patients. CONCLUSION: LDH might be a good predicting factor for the requirement of respiratory support and development of PPHN among MAS patients.

OBJECTIVES: The aim of this study was to compare the push-out bond strengths of resin cement/fiber post systems to post space dentin using different application methods of resin cement. MATERIALS AND METHODS: Thirty extracted human premolars were selected and randomly divided into 3 groups according to the technique used to place the cement into root canal: using lentulo-spiral instrument (group Lentulo), applying the cement onto the post surface (group Direct), and injecting the material using a specific elongation tip (group Elongation tip). After shaping and filling of the root canal, post space was drilled using Rely-X post drill. Rely-X fiber post was seated using Rely-X Unicem and resin cement was light polymerized. The root specimens were embedded in an acrylic resin and the specimens were sectioned perpendicularly to the long axis using a low-speed saw. Three slices per each root containing cross-sections of coronal, middle and apical part of the bonded fiber posts were obtained by sectioning. The push-out bond strength was measured using Universal Testing Machine. Specimens after bond failure were examined using operating microscope to evaluate the failure modes. RESULTS: Push-out bond strengths were statistically influenced by the root regions. Group using the elongation tip showed significantly higher bond strength than other ways. Most failures occurred at the cement/dentin interface or in a mixed mode. CONCLUSIONS: The use of an elongation tip seems to reduce the number of imperfections within the self-adhesive cement interface compared to the techniques such as direct applying with the post and lentulo-spiral technique.

PURPOSE: Perinatal asphyxia is a major factor correlated with diseases that cause respiratory distress in a neonate. So we aimed to investigate the relationship between respiratory distress syndrome (RDS) and transient tachypnea of newborn (TTN) with plasma biological markers of perinatal asphyxia in full-term neonates. METHODS: Full-term neonates with transient tachypnea of the newborn (TTN) and respiratory distress syndrome (RDS) who were admitted within 24 hours after birth were enrolled in a study group. And control group are infants with premature rupture of amniotic membrane without significant findings. Serum lactate dehydrogenase (LDH), aspartate transaminase (AST), alanine transaminase (ALT), creatine kinase (CK) and myoglobin were measured at admission. RESULTS: Of the total 80 infants, 54 were of the study group and 26 were of the control group. The numbers of RDS and TTN groups were 27 and 27, and the numbers of RDS with hypoxic-ischemic encephalopathy (HIE) and RDS without HIE were 6 and 21 retrospectively. Serum AST, ALT, LDH and CK were significantly higher in the study group than the control group (P<0.05). When RDS group and TTN group were compared AST and LDH were significantly higher in RDS group than TTN group (P<0.05). Serum AST, ALT and LDH were significantly higher in RDS with HIE group than RDS without HIE group (P<0.05). A prediction of RDS by LDH analysis showed good correlation by receiver operating characteristic curve (P<0.05). A cut off level of 720 IU/L for LDH was the best predictor of RDS (sensitivity 63% and specificity 86%). CONCLUSION: LDH is an excellent predictor to differentiate RDS from TTN soon after birth in full-term neonates with respiratory distress.

BACKGROUND: Several studies have shown that negative mental health increases risky health behavior and mortality risk. We investigated the relationship between mental health and health behavior, and the causal association between mental health and mortality risk. METHODS: We used data from the 8-year (2006–2014) Korean Longitudinal Study of Aging with a cohort of 10,247 individuals (whom we divided into a younger group aged <65 years and an older group aged ≥65 years). Mental health was assessed with the following factors: depression, social engagement, and satisfaction of life. Health behavior was assessed with smoking, alcohol use, and regular exercise. Mortality risk was calculated using survival status and survival months as of 2014. Multiple logistic regression and Cox proportional hazard analysis were performed. RESULTS: Negative mental health was associated with current smoking and sedentary life style, but not with alcohol consumption. In addition, it was associated with an increase in all-cause mortality risk. The increase in mortality risk in the highest quartile (vs. lowest) was 1.71 times (hazard ratio [HR], 1.71; 95% confidence interval [CI], 1.12–2.62) and 2.07 times (HR, 2.07; 95% CI, 1.60–2.67) for the younger and older group, respectively. CONCLUSION: Our results show that mental health affects health behavior and mortality risk. A key inference from this study is that improving mental health can lead to positive changes in health behavior and reduce the risk of mortality.
