The purpose of this study is to investigate the inelastic behavior of precast segmental prestressed concrete bridge piers. A computer program, named RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology), for the analysis of reinforced concrete structures was used. Material nonlinearity is taken into account by comprising tensile, compressive and shear models of cracked concrete and a model of reinforcing steel. An unbonded tendon element based on the finite element method, that can represent the interaction between tendon and concrete of prestressed concrete member, is used. A joint element is newly developed to predict the inelastic behaviors of segmental joints. The proposed numerical method for the inelastic behavior of precast segmental prestressed concrete bridge piers is verified by comparison with reliable experimental results.

It has been 1 year since Sewol Ferry disaster occurred in the Gwanmaedo sea of Jindo, Jeollanamdo, on Apr. 16, 2014. The Sewol Ferry Disaster which took 304 lives and had some victims still missed has become the largest tragic accident in Korea since 2010. Although one year has passed since the disaster, there is no psychological communication research on the trauma of the victims' families. This study first investigated the actual state of the Sewol Ferry victims' parents suffering from post-traumatic stress disorder (PTSD) after their losses of children by the disaster. This study revealed that the victims' families suffer from physical and psychological the PTSD but neglect treatment. The PTSD still influences their daily life. It was observed that the victims' families have a lot of difficulties with interpersonal relationship, relationship with co-workers, residence, values, and other kinds of daily life. Given that the victims' families have a great deal of PTSD after the disaster, the academic circle needs to make discussions of the issue actively in order to heal the pains of the Sewol Ferry victims' families who are unattended in our society.

Although the biosignal is the best way to represent the human condition, it is difficult to acquire the biosignal of a driver driving for detecting driver's condition. As one of the methods to overcome this limitation, this paper proposes a driving stress monitoring system based on information provided by OBD-II(on-board diagnostics version II). The driving information and EDA(Electrodermal activity) data are obtained through the OBD-II scanner and E4 wristband, respectively. EDA data is used as ground truth to distinguish whether driver is stressed or not. MLP(multi-layer perceptron) neural network is used as a model to detect driving stress and is trained using driving data for about a month. To evaluate the proposed system, we used about 1 hour of driving data and the accuracy is 92%.

This study was conducted to investigate the relationship between depression and communication skills and clinical practice stress among college nursing students. This study targeted 208 nursing college seniors in B city who have experience in clinical practice. Data were collected from September 1-30 2017 and were analyzed using descriptive analyses, t-tests, ANOVA, Pearson's correlation, and Stepwise multiple regression with the SPSS WIN 21.0 program. The average score of communication skills was 3.73, the score of depression was 2.36, and the score of clinical practice stress was 2.88. Significant differences were found in clinical practice stress depending on gender (p=0.002), age (p=0.048), grade (p=0.001), satisfaction with college life (p<0.001), satisfaction with major (p=0.002), desired course (p=0.002), and satisfaction with clinical practice (p<0.001). Clinical practice stress was negatively related to communication skills (r=-0.17, p=0.016) and positively related to depression (r=0.37, p<0.001). Depression, satisfaction with clinical practice, grade, sex and religion had a high explanation rate of 26.9%, indicating that they were meaningful variables that influenced clinical practice stress. Overall, to decrease clinical practice stress among nursing students, it is necessary to develop an intervention program that can prevent and mitigate depression and improve communication skills.

This study was conducted in order to analyze job stress factors of radiotechnologists in order to inprove the work efficiency and to organize system management plans. For data collection, total 261 radiotechnologists, who work in Busan, took part in structured questionnaire survey. The collected data were analyzed by using SPSS/PC+ Win 13 version. For verification of the differences among groups, one-way ANOVA was executed. For analyzing efficiency of system, which is affected by job stress, multiple regression analysis was taken. First, work stress classified by age group was found as the biggest stress factor among radiotechnologists in their 30s. Among radiotechnologists in their 20s, 40s and 50s, the biggest stress factor was communication problems. In terms of, job stress classified by division, no statistical difference was observed among groups. Second, as the result of system efficiency analysis, high values were found in organizational immersion and job satisfaction among radiotechnologists in their 20s and oncology division has the highest values in concentrating the system and job satisfaction. For this result, statistically significant differences were observed among groups. Third, in terms of the sub-factors of work stress, communication problem was found as the variable that exerted statistically significant impact to organizational effectiveness. However, no statistically significant differences were observed inadministrative and personal problems. Job stress decreases as communication within the organizations or communication with other divisions becomes more successful. In other words, system efficiency can be enhanced by decreasing conflicts within organization through successful communication.

This study attempted to implement fundamental data to understand the relationship between self esteem and stress-coping strategies of current students in health related colleges for the development of a program related to school life and guidance. This study involved 244 willfully participating college students from six health related colleges in the Honam area. Data from self administered questionnaires regarding self esteem and stress-coping strategies were collected from November 1 to December 21, 2008. The results of the study showed self esteem was high when general characteristics of religion and a very harmonious relationship with classmates were present. Higher usage of active stress-coping strategies occurred as the year in college and mother's education increased. Active implementation of passive stress-coping strategies were used when religion and residing in rural areas were present. Self esteem was higher as active stress coping strategies (i.e. problem focus and social support) improved. As passive stress-coping strategies (i.e. emotional relief and desire management) improved so did self esteem. By and large as stress-coping strategies increased for college students so did self esteem. As a result, as we search for stress-coping strategies pertaining to studies, practices, and future employment of college students, preparation of a regular course of study that includes curriculum, which increases self esteem should be made. Also consideration should be given to programs that promote relations between students and students and their advising professors.
