본 연구에서는 팽창형 막 구조물의 대변형 특성을 수치적 그리고 실험적으로 살펴보았다. Miller와 Hedgepeth의 막 이론을 이용하여 주름 효과를 고려한 막재료 구성방정식을 FORTRAN으로 해석 알고리즘을 만들어 user material(UMAT) subroutine을 개발하였다. 개발된 주름 해석 UMAT subroutine을 상용 해석 프로그램 ABAQUS와 연계 해석하여 팽창형 막 구조물의 주름 영역과 변형된 형상 특성 연구를 수행하였다. The large deformation of inflatable membrane structure is numerically and experimentally considered in this paper. The numerical algorithm of wrinkling based on Miller and Hedgepeth membrane theory is developed using user material(UMAT) subroutine written by FORTRAN. Wrinkled area and deformed shapes of inflatable membrane structures are investigated by using ABAQUS with UMAT subroutine of wrinkling algorithm.

본 연구에서는 형상기억합금 작동기의 열-기계적 특성과 구조물의 응용을 살펴보았다. Lagoudas 모델을 기본으로 3-D 형상기억합금의 구성방정식을 FORTRAN으로 해석 알고리즘을 만들어 user material(UMAT) subroutine을 개발하였다. 개발된 형상기억합금 해석 UMAT subroutine을 상용 프로그램 ABAQUS와 연계 해석하여 형상기억합금 작동기와 주구조물간의 상호 특성을 수치적으로 살펴보았다. In this research, the thermomechanical responses of shape memory alloy(SMA) actuators and their applications in the structures combining strip SMA actuators are investigated. The numerical algorithm of the 3-D SMA thermomechanical constitutive equations based on Lagoudas model is developed using user material(UMAT) subroutine written by FORTRAN. For the numerical results, the ABAQUS finite element program has been utilized with UMAT subroutine of the numerical algorithm of SMAs. The interactions between the host structure and SMA strip actuator are numerically investigated.

Objective : The purpose of this study was to verify the effect of a single-session, positive psychology-based, strength-enhancing workshop for psychiatrists. The program is composed of lecture about positive psychology and workshop activities for identifying and utilizing character strengths. Methods : A total of 42 psychiatrists participated in this study. The program consisted of a lecture about positive psychology and workshop activities for identifying and utilizing character strengths. Results of a positive resources test, given before and after the session, were used to assess changes in the personal positive resources of the participants as a result of the program. Results : We noted significant increases in participants' satisfaction with life, positive affect, gratitude, acceptance, positive and cognitive emotion regulation, orientation of life, growth, spirit, autonomy, social support, and care factors after completion of the program. On additional analysis, spirit and care scores of female participants's were significantly increased than male participants's. Conclusion : The findings are meaningful in verifying the efficacy of a short-term intervention to improve psychiatrists's positive resources.

Objective : The purpose of this study was to verify the differences of expressed character strengths graded as per the Korean Strength Scale, based on the type of work. Methods : A total of 2,444 conglomerate workers were classified into two groups: 1,356 office workers and 1,088 production workers. The subjects were examined through a web or mobile application based on the Korean Strength Scale. The Korean Strength Scale consists of a total of four top entries and 25 sub-items with appropriate validity. Results : The difference in the average score of sum of character strengths between the two groups was not significant. In the office worker group, character strengths such as love of learning, creativity, perspective, curiosity, facilitation, judgment and faith had significantly high scores. On the other hands, modesty, hope, gratitude, sincerity, magnanimity and self-regulation were high in the production worker group. The results remained unchanged in additional analysis of covariants as sex, age and education level, except for self-regulation and faith. Conclusion : Our results suggest significant differences in the character strengths between the two types of work; however, the average of sum of character strength score remains unchanged. These results may help to understand differences between work environments and thus help to establish a positive foundation.
