The objectives of the present research are twofold. First, this research aims to compare the effect of trait characteristics(sensation seeking, social resistance and type-A behavior) with that of driving specific characteristics(driving anger and type-A driving) on problematic driving behavior. Second, the role of life stress as a mediator in the relationships between general trait characteristics and traffic safety index was examined. 1158 licensed commercial vehicle drivers were surveyed and their accident-related records were obtained in this research. Results showed that driving specific characteristics were significant indicators of traffic safety and life stress mediated the relationships between general trait characteristics and traffic safety index. These findings implicate that understanding drivers' driving specific characteristics and their levels of life stress is important to reduce problematic driving behaviors and enhance traffic safety.

This study used the raw data of the 15th (2019) Korean Youth Health Risk Behavior Survey to investigate the risk factors of the health-risk behaviors of Korean multicultural adolescents on the subjective oral symptoms. The scope of the multicultural family was limited to children of immigrant women's families married to Korean men and immigrant male families married to Korean women, and 572 were selected as the final study subjects. The sociodemographic variables were surveyed as gender, grade, economic level, and school performance. The health risk behaviors included drinking, smoking, medication, stress, sleep satisfaction, suicidal thoughts, depression, and brushing before bedtime. The oral symptoms examined were toothache, gum pain, and halitosis. As a result, toothache was related to drinking, toothbrushing before sleep, stress, sleep satisfaction, suicidal thoughts, and depression. Gum pain was associated with drug use, sleep satisfaction, suicidal thoughts, and depression. Halitosis was associated with medication, brushing before sleep, stress, suicidal thoughts, and depression. In terms of health risk factors, drinking, stress, and sleep satisfaction were risk factors for toothache. Smoking, sleep satisfaction, and suicidal thoughts were risk factors for gum pain. The presence of toothbrushing and stress were risk factors for halitosis. In conclusion, a policy system is needed to support oral health education programs nationally at times, such as after-school activities or club activities, to promote oral health for teenagers.

The present study examined patterns of co-occurrence between DSM-5 posttraumatic stress disorder(PTSD) symptoms and posttraumatic growth(PTG) among Korean populations(n= 860). Latent profile analysis was used to identify subclasses and suggested that the 3-class model fit best: (1) Low PTSD/Mild PTG group (2) Low PTSD/High PTG group; (3) High PTSD/High PTG group. Class membership was predicted by demographic variables, social isolation, and frequency of traumatic experiences. Classes also differed with respect to self-destructive behaviors(binge eating, non-suicidal self-injury, and problem drinking). These findings contribute to future research about the coexisting patterns of PTSD and PTG, and to identify high-risk individuals who suffer from trauma-related problems in clinical practice.

The purpose of the present study was intended to assess psycosocial stress of male researchers working in a Research Institute, and to reveal the relationship between psycosocial stress and coronary risk factors. Data were obtained from 356 male researchers who underwent health package check-up at the health promotion center of a university hospital from May to June 2007, using by self-administered questionnaire & health check-up. For psycosocial stress, we used the questionnaire with 18 items developed as Psychosocial Well-bing Index(PWI). For coronary risk factors, systolic and diastolic blood pressure(SBP, DBP), triglyceride(TG), total cholesterol(TC), high and low density lipoprotein cholesterol(HDL, LDL), fasting blood sugar(FBS) and % fat rate were measured. As a results, the level of psycosocial stress is influenced by socio-demographic characteristics, job-related characteristics and health-related behaviors. Especially, it was found to have the inter-relational effects that the higher the blood pressure, the higher the level of psycosocial stress.

In this study, customer service representatives in call centers, the relevance of occupational stress, and turnover intention as well as the investigation of the relevance to that of demographic characteristics, health behaviors, and job-related characteristics is carried out. In particular, the relevance of occupational stress and turnover intention was attempted to be identified. From the response to the surveys of nine hospitals and five companies, there was a total of 158 people during the investigation. The collection of data was conducted by self-administered questionnaire in the period of February 1, 2013 to June 30, 2013. As the result of study, factors related to turnover intention involved age, sleep, job demands and job autonomy as significant variables. In particular, in the relevance of occupational stress and turnover intention, it was revealed that turnover intention decreases as job autonomy increases while turnover intention increases as job demands become higher. The ratio of danger of occupational stress on turnover intention eminently increased in the group of high job demands, low job autonomy, low support of supervisor and co-worker. Therefore, it is considered that efforts for improvement of occupational stress factors are required to decrease turnover intention.

This paper is dedicated to the buckling behaviors of strengthened perforated plates under edge shear loading, which is a typical load pattern of steel plates in civil engineering, especially in plate and box girders. The square plates considered each has a centric circular hole and is simply supported on four edges in the out-of-plane direction. Three types of strengthening stiffeners named ringed stiffener (RS), flat stiffener (FSA and FSB) and strip stiffener (SSA, SSB and SSC) are mainly discussed. The finite element method (FEM) has been employed to analyse the elastic and elasto-plastic buckling behavior of unstrengthened and strengthened perforated plates. Results show that most of the strengthened perforated plates behave higher buckling strengths than the unstrengthened ones, while the enhancements in elastic buckling stress and elasto-plastic ultimate strength are closely related to stiffener types as well as plate geometric parameters including plate slenderness ratio and hole diameter to plate width ratio. The critical slenderness ratios of shear loaded strengthened perforated plates, which determine the practical buckling pattern (i.e., elastic or elasto-plastic buckling) of the plates, are also studied. Based on the contrastive analyses of strengthening efficiency considering the influence of stiffener consumption, the most efficient cutout-strengthening methods for shear loaded perforated square plates with different slenderness ratios and circular hole diameter to plate width ratios are preliminarily identified.

The present study aims to evaluate the nonlinear and post-buckling behaviors of orthotropic graphene sheets exposed to end-shortening strain by implementing a semi-Galerkin technique, as a new approach. The nano-sheets are regarded to be on elastic foundations and different out-of-plane boundary conditions are considered for graphene sheets. In addition, nonlocal elasticity theory is employed to achieve the post-buckling behavior related to the nano-sheets. In the present study, first, out-of-plane deflection function is considered as the only displacement field in the proposed technique, which is hypothesized by an appropriate deflected form. Then, the exact nonlocal stress function is calculated through a complete solution of the von-Karman compatibility equation. In the next step, Galerkin's method is used to solve the unknown parameters considered in the proposed technique. In addition, three different scenarios, which are significantly different with respect to concept, are used to satisfy the natural in-plane boundary conditions and completely attain the stress function. Finally, the post-buckling behavior of thin graphene sheets are evaluated for all three different scenarios, and the impacts of boundary conditions, polymer substrate, and nonlocal parameter are examined in each scenario.
