This paper is proposed to select the optimal finite element type in finite element analysis. Based on the NUREG reports, static analyses were performed using a commercial analysis program, $ABAQUS^{TM}$. In this study, we used a nonlinear kinematic hardening model proposed by Chaboche. The analysis result of solid elements by inputting the same material constants was different from the results of the NUREG report. This is resulted from the difference between shell element and solid element. Therefore, the material constants that have similar result to the experimental result were determined and compared according to element type. In case of using solid element for efficient finite element analysis, we confirmed that the use of C3D8I element type(incompatible mode 8-node linear brick element) leads the accurate result while reducing the analysis time.

허은주(Heo, Eun Ju),김세범(Kim, Sae Bum) 한국서비스경영학회 2014 서비스경영학회지 Vol.15 No.1

Domestic beauty medical market becomes increasingly competitive due to the increase of practitioners as well as the increase of the non-insurance beauty medical service. Previous studies related to existing communication are mainly centered on nonverbal communication. The studies on hospital where verbal and nonverbal communication occurs at the same time are mainly focused on general hospital or university hospital. In this sense, attention on beauty medical market is insufficient. The purpose of this study is to identify the effect of verbal as well as nonverbal communication on trust, customer satisfaction, customer loyalty in cosmetic surgery and beauty medical market. According to the empirical analysis, verbal communication of medical service providers showed positive effects on trust. Kinesics and proxemics also showed positive effects on trust. However, paralanguage and physical appearance failed to show a positive effect on trust. Trust is the factor that affect customer satisfaction. The higher customer satisfaction is, the higher positive effect on customer loyalty is.

The market of cosmetic medicine is characterized as interactive relations between workers and customers through which beauty products and services are provided and transacted. In that market, customer satisfaction and behaviors may vary depending on what perceptions customers have in making those relations. The purpose of this study was to examine the effects of relational benefits on customer satisfaction and relational continuance intention in the market of cosmetic medicine, providing basic information to identify factors ensuring long-term relationships with customers in that market and set up effective strategies to maximize those factors. Besides, this study examined the mediating effects of relational frequency between relational benefits, customer satisfaction and relational continuance intention. Participants of this study were users of the dermatology department or the private clinic specializing in beauty care who have ever visited the medical department or that clinic more than 3 times. Those participants were selected through the convenience sampling method. This study conducted a questionnaire survey. Of 280 surveyed, 247 respondents were considered to be reliable and used for the final analysis. Data from the survey were analyzed empirically using the descriptive analysis and the reliability analysis with SPSS 19.0. In addition, the confirmatory factor analysis and the path analysis were conducted using AMOS 21.0. The mediating effects of relational frequency were also investigated. The findings of this study can be summarized as follows. First, some sub-areas of relational benefits like confidence benefits, customization benefits were found to have positive effects on customer satisfaction. social benefits. Economic benefits were found not to positively affect customer satisfaction. Second, customer satisfaction brought by relational benefits was found to have positive influences on relational continuance intention. Third, the mediating effects of relational frequency were examined to find that for customers who visited the dermatology department or the private beauty clinic, some sub-areas of relational benefits like economic benefits and customization benefits had significant effects on customer satisfaction.

일차수응력부식균열 개시 모델과 거시적 현상학적인 손상역학 접근론에 기반한 유한요소 손상해석을 수행하여 Alloy 600TT 로 제작된 원전 증기발생기 전열관에 발생하는 일렬 원주방향 표면 일차수응력부식균열의 성장에 미치는 균열 간격의 영향을 고찰하였다. 기존 연구 결과와의 비교를 통해 손상해석 방법의 타당성을 검증하였다. 검증된 방법을 일렬 원주방향 표면 일차수응력부식균열에 적용하였다. 적용한 결과, 단일 균열에 비하여 일렬 균열의 경우 보다 빠른 합체시간과 관통시간을 보이며 균열 간격이 증가할수록 합체시간과 관통시간은 증가함을 확인하였다. 또한 일정 간격이상으로 두 균열이 떨어지면 합체 이전에 관통될 수 있음을 확인하였다. The study investigated the effect of the distance between two collinear circumferential surface cracks on the primary stress corrosion crack (PWSCC) growth in alloy 600TT steam generator tubes using a finite element damage analysis based on the PWSCC initiation model and macroscopic phenomenological damage mechanics approach. The damage analysis method was verified by comparing the results to the previous study results. The verified method was applied to collinear circumferential surface PWSCCs. As a result, it was found that the collinear cracks showed earlier coalescence and penetration times than the a single crack, and the times increased with the distance. In addition, it is expected that penetration may occur before coalescence of two cracks if they are more than a specific distance apart.

The tensile test is required to determine the mechanical properties of a material. Finite element analysis is performed with true stress-strain curve which is obtained from tensile test results. In this study, a commercial program, ABAQUS<SUP>TM</SUP> was used to simulate the test of the standard tensile specimen. From the analysis, a slight difference in the shape of specimen models during the tensile test simulation was confirmed that the specimen shape affected the simulation results. Therefore, an appropriate model shape for finite element analysis was determined by the results.
