The purpose of this study is to document the stress symptoms (Anxiety and depression) among dental students and the difference of stress level between classes and by gender. All students in dental college, Seoul National University, in the 1995 academic year, were tested with the Spielberger's State-Trait Anxiety Inventory and Beck Depression Inventory just before the first semestral examination when the stress levels of students are expected to be the highest. 303 students answered the test. The obtained results were as follows : 1. State Anxiety inventory scores of the second-year and first-year students were significantly higher than those of the fourth -year and third-year(p(0.01), and all classes showed mean state anxiety scores more than mild. 2. Trait Anxiety inventory scores of the second-year and first-year students were significantly higher than those of the third-year and forth-year(p(0.01), and all classes showed mean Trait Anxiety scores more than mild. 3. Beck Depression inventory scores of the second -year students were significantly higher than those of the third-year and fourth-year(p(0.01), and twenty two students(7.3%) among the fourth classes showed depression symptoms. 4. In the comparison of the mean scores of the State-Trait Anxiety Inventory and Beck Depression Inventory between male and female students, State Anxiety Inventory scores of the second-year female students were significantly higher than those of the second year male students(p(0.05), and there was no significant difference elsewhere.

Purpose: The purpose of this study was to investigate the effects of general, health, and alcohol-related characteristics on blood pressure and stress according to the Alcohol Use Disorders Identification Test (AUDIT). Methods: This was a descriptive study. From participants in the 2013 Korea National Health and Nutrition Examination Survey, 319 participants who responded to the survey when they were attending college or university were selected. Data were analyzed using the SPSS Win 23.0 program for composite sample data reflecting the composite design elements of stratification, colonization, and weighting. Results: Mean age of onset of alcohol drinking was $17.91{\pm}0.16$ years, the average AUDIT score was $7.56{\pm}0.41$, and 25 (9.1%) participants fell into the high-risk drinking group. In the high-risk AUDIT group, systolic blood pressure was influenced by age, gender, institution, health status, body mass index, and suicidal ideation, and the explanatory power of the model ($R^2$) was 75.0%. For diastolic blood pressure, institution and health status were the influential factors, and $R^2$ was 66.2%. Predictors of stress were health status, depression, and the age of onset of drinking, and $R^2$ was 57.2%. Conclusion: It was confirmed that the explanatory power of the variables in models of systolic and diastolic blood pressure and stress is greater in those with higher scores on AUDIT.

This study was a secondary data analysis conducted to identify the factors affecting the health-related quality of life according to the stress perception level of middle-aged. Data from the 2014, 2016, and 2018 Korean National Health and Nutrition Examination Survey were used, and 7,995 people aged 40-64 who answered the level of stress perception were targeted. Data analysis was performed using IBM SPSS ver.25.0, and the significance level was set to .05. As a result of the study, in the feeling less stressed group, household income level, education level, frequency of dinning out, drinking amount at a time, smoking, subjective health, and depression were found to be significant influencing factors, and the explanatory power was 21.4% (p < .001). In the feeling a lot stressed group, household income level, education level, living with a spouse, weekly breakfast frequency, aerobic physical activity, smoking, subjective health, and depression were significant influencing factors, and the explanatory power was 38.7% (p < .001). Therefore, it is suggested to consider each influencing factor in the middle-aged stress reduction intervention.

Purpose: This study aimed to investigate sex differences in the effect of body mass index (BMI) and stress on high-risk diabetes mellitus (DM). Methods: Secondary analysis of data from 4,271 male and female adults participating in the Sixth Korea National Health and Nutrition Examination Survey 2015 was performed. The participants were evaluated using questionnaires and blood tests. Data were analyzed using descriptive statistics, t-test, ${\chi}^2-test$, and multiple logistic regression analysis (SPSS 24.0). Results: To identify sexspecific effects, interaction variables were included. Hemoglobin A1c (HbA1c) level was higher in men than in women, and the risk of DM decreased 0.31 times in women compared to that in men. As age increased, the odds of risk DM increased 1.03. The risk of DM increased 1.99 times in overweight individuals and 2.79 times for obese individuals compared to that in individuals with normal weight. Stress levels were higher in women than in men, but stress is not an influential factor in high-risk DM. In age-sex interaction, the odds of risk DM increased 1.02 in women compared to that in men as age increased. Conclusion: HbA1c level was affected by age-sex interaction, and age and sex should be considered in the application of HbA1c in the diagnosis of DM.

Purpose: This study aimed to investigate the factors affecting cardiovascular disease in middle-aged male workers. Methods: The participants were 137 male office workers over 40 years old and under 60 years old working in small- and medium-sized workplaces from three southern provinces of Korea. Data were collected through self-reported questionnaires and health screening reports from the 2014 National Health Examination. The influencing factors included general characteristics of participants, anger expression style, and occupational stress. Data were analyzed using t-test, ANOVA, and regression analysis with SPSS 22.0. Results: The mean score of risk of cardiovascular disease was 6.73±4.69 and there were significant differences in exercise (t=2.13, p=.035) working time (t=-2.15, p=.034). Logistic regression analysis showed that, when adjusted for exercise and working time, the probability of becoming under a cardiovascular disease risk was 21% higher for those who anger-in (OR=1.21, 95% CI=1.02~1.44, p=.027) and 12% higher for those perceived occupational stress (OR=1.12, 95% CI=1.01~1.24, p=.030). Conclusion: The results suggest developing the strategies for middle-aged male workers to encourage exercise and to decrease occupational stress, as well as an appropriate anger expression style to improve holistic aspect of health considering their demographic characteristics.

Recent deepwater offshore structures in Gulf of Mexico utilize butt welded tubular joints. Application of welded tubular joint includes tendons, production risers, and steel catenary risers. Fatigue life assessment of these joints becomes more critical because the structures to which they are attached are allowed to undergo cyclic and sometimes large displacements around an anchored position. Estimating the fatigue behavior of these tubular members in the design stage is generally conducted by using S-N curves specified in the codes and standards. Applying the stress concentration factor of the welded structure to S-N approach often results in very conservative assessment because the stress field acting on the tubular has a non-uniform distribution through the thickness. Fracture mechanics and fitness for service (FFS) technology have been applied in the design of the catenary risers. This technology enables the engineer to establish proper requirements on weld quality and inspection acceptance criteria to assure satisfactory structural integrity during its design life. It also provides guidance on proper design curves to be used and a methodology for accounting for the effects of non-uniform stress distribution through the wall thickness. An attempt was made to develop set of S-N curves based on fracture mechanics approach by considering non-uniform stress distribution and a threshold stress intensity factor. Series of S-N curves generated from this approach were compared to the existing S-N curves. For flat plate butt joint, the S-N curve generated from fracture mechanics matches with the IIW class 100 curve when initial crack depth was 0.5 mm (0.02"). Similar comparison with API X′ was made for tubular joint.. These initial crack depths are larger than the limits of inspection by current Non-destructive examination (NDE) means, such as Automatic Ultrasonic Inspection (AUT). Thus a safe approach can be taken by specifying acceptance criteria that are close to limits of sizing capability of the selected NDE method. The comparison illustrates conservatism built into the S-N design curve.

This study was performed to identify the level of stress recognized by the parents as a support system for their infant patients who were hospitalized in an emergency department, thus to provide the resulting data as the basic material of care intervention for the families of infant patients. This study subjected the parents with infant patients who were hospitalized in emergency department of C University Hospital in Daejeon, and the data was collected from questionnaires for them, dating from Mar. 20, to Jun. 24, 2001 This study used the tool(30 questions) which was originally developed by Ji, Dong-ok (1992) for measuring the stress of families of infant patients in emergency room, and then was modified and complemented by this researcher suitably for infant patients. Collected data was statistically analyzed with frequency, percentage, mean, standard deviation, t-test, ANOVA, by using SPSS WIN10.0 program, and the results were as follows: 1. The stress of parents with infant patients hospitalized in emergency department averaged 3.31 on the basis of 5-point measure, which means that they felt stress beyond means. 2. The factor with high average out of stress factors the parents of infant patients recognized included the followings: 'about the pain of infant patients due to examination(3.91±1.00)'; 'about rare opportunity to be in contact with physician(3.78±1.09)'; 'delay in emergent treatment required for infant patients(3.75±1.31)'; 'delay in the general treatment of infant patients(3.72±1.32)'. Factors of the stress level includes the followings: 'care and medical treatment'(3.46±.72); 'body and diseases'(3.41±.97)'; 'lack of information and supportable resources (3.25±.77)'; and so on. 3. For the stress level according to general characteristics, there were statistically significant differences in the result of the condition of infant patients, medical treatment(P<.01), religion, the procedure of treatment(P<.05). With little preceding studies for infant patients hospitalized in emergency department, this study looked through the level of stress recognized by the parents of infant patients. Based on the comprehension on the parents with infant patients and the knowledge on stress factors recognized by the parents, it is expected that we can seek the methods of care intervention such as explanation of care and treatment procedures, unit policies, continuous interest and emotional supports as well as the provision of information to understand the responses of parents and reduce accompanied stresses.

Purpose: The objective of this study was to provide a trend analysis of the prevalence of diabetes relative to the socioeconomic, lifestyle, and physiologic risk factors among Korean adults aged over 30 years for a 10-year period using data from the Korean National Health and Nutrition Examination Survey. Methods: Prevalence difference and the slope index of inequality were calculated for each risk factors using binomial regression by considering the repeated cross-sectional features of the data. The prevalence ratio and the relative index of inequality were calculated using log-binomial regression. Linear trend tests were performed using SAS 9.2. Results: Crude prevalence of diabetes increased over the 10-year period, and was higher for men than for women. It was very high for adults 60 years or over, consistently increasing over time. The prevalence among unemployed men, women with higher level of stress, women with hypertension, and adults with serum triglyceride levels over 135 mg/dL increased over the 10-year period in comparison with the respective control group. Conclusion: Considering the rapid economic development and associated lifestyle changes in Korea, action should be taken to control the prevalence of diabetes by both preventing and consistently monitoring these identified risk factors using a public-health approach.
