As a key reinforcement connection between a tower and a substructure in offshore wind turbine system, the transition piece is inevitably subjected to cyclic dynamic environmental loads such as wind, current and wave. Therefore, well designed transition piece with high strength and good fatigue resistance is of great significance to the structural safety and reliability of offshore wind power systems. In this study, the structural behavior of the transition piece was studied by an extensive sets of finite element analyses. Three widely used types of transition piece were considered. The characteristics of stress development, fatigue life and weight depending on the type of the transition piece were investigated in the ultimate limit state (ULS) and the fatigue limit state (FLS) of a 5-MW offshore wind turbine to be placed in Korea. An optimal form of the transition piece was proposed based on this parametric study.

This study focuses on the beginning of transition to parenthood expectation and applies the exchange theory in order to examine reward and cost of transition to parenthood expectation and picks up the main cause effecting it. This study conducted structured questionnaires to total 330 first pregnant women and examined descriptive statistics and t-test F-test analysis by using collected data. And here are the result of research. First the transition to parenthood expectation expected rewards much more than costs and had much importance on individual aspects in parenthood. The more were they aged hardly educated and housewives the higher did they showed expectation of reward. The less did they have high education the more did they expect costs of the transition to parenthood expectation. Second to examined the reward/cost of transition to parenthood expectation according to martial satisfaction the more did they have martial satisfaction the more did they expectation of the rewa ds on transition to parenthood expectation. On the contrary the more did they respect from husbands the less did they cost of transition to parenthood expectation. This study would be helpful to lead family life having childbirth to the positive way be examining the process from childbirth plan to delivery.

Purpose: Although the term "transition to motherhood" is commonly used in research, the concept is not clear. This study, hence, was conducted to clarify the concept of "transition to motherhood." Methods: The concept analysis framework developed by Walker and Avant is used to analyze the concept of transition to motherhood. Results: Transition to motherhood is defined as the physical, psychological, social, and relational (mother-baby relationship/interpersonal relationship) changes that happen to a woman after pregnancy and delivery of a baby. The attributes of the transition to motherhood include: 1) adapting to physical changes after pregnancy and childbirth; 2) experiencing various psychological changes; 3) changing of her social perception from being a woman to someone's mother; and 4) forming and developing a relationship with the newborn, adjusting priorities, and redefining the relationship between family and others. Meeting the newborn is regarded as an antecedent of the transition to motherhood. Redefining identity and physical image, ensuring mother's well-being, maternal attachment, and confidence in the maternal role are regarded as consequences of the transition to motherhood. The concept was clarified by the presentation of model, borderline, and contrary cases. Conclusion: The significance of this study lies in the clarification of the concept of transition to motherhood and defining its attributes. It is recommended that tools be developed to measure transition to motherhood based on the results of this study. Furthermore, nurses and midwives can use study findings to better understand the concept of transition to motherhood in providing care and support to mothers who experience it.

Prevalence of Agile methods in software companies is increasing dramatically. Software companies need to employ these methods to overcome the inherent challenges of traditional methods. However, transitioning to Agile approach is a topic of debate and there is no unique and well-defined transition model or framework yet. Although some research studies have addressed barriers and strengths behind the successful Agile deployment, it seems that this process still needs to be studied more in depth. The rationale behind this is the socio-technical nature of Agile transition and adoption. Particularly, the challenges and problems that software companies are facing during Agile transition, show that this process in more difficult than expected. Conducting a large-scale research study revealed that Agile transition and adoption process needs to be supported by several critical prerequisites. This study adopted a Ground Theory with the participation of 49 Agile experts from 13 different countries and empirically identified seven transition prerequisites. These prerequisites focus on the different aspects of the transition. The main aim of this paper is proposing these prerequisites and theoretical and practical implication of these prerequisites. Providing these prerequisites before moving to Agile increases chance of success in Agile transition and adoption and leads to fewer challenges during the change process.

Objectives: This study aimed to provide basic data for the development of clinical practice-related education program by analyzing the effects of grit, job satisfaction, and retention intention on transition shock of new dental hygienists. Methods: From April 19 to July 4, 2022, the data was collected from 200 new dental hygienists working for dental hospitals/clinics. Using the SPSS Statistics ver. 22.0, this study was conducted the t-test, one-way ANOVA, Pearson's correlation analysis, and multiple regression analysis. Results: There were positive correlations between grit, job satisfaction, and retention intention, a negative correlation between grit and transition shock, a positive correlation between job satisfaction and retention intention, a negative correlation between job satisfaction and transition shock. and a negative correlation between retention intention and transition shock. As the factors affecting transition shock, lower pay and main performance of medical cooperation work increased transition shock. When job satisfaction and retention intention were higher, transition shock decreased. Conclusions: In order to reduce transition shock of new dental hygienists, it would be necessary to operate clinical practice-related training program, and also to establish a training environment similar to the clinical site/context/situation similar to clinical context/situation.

Objective: Using data from the Panel Study on Korean Children, this study investigated the influence of teacher'thoughts about the transition from ECEC to primary school in relation to learner-centered teaching methods and children's school adjustment. Methods: We analyzed the longitudinal data of 658 seven-year-olds from the 8th and 9th waves of the panel study of Korean children collected by the Korea Institute of Child Care and Education in 2015 and 2016. The main analysis method was Structural Equation Modeling(SEM). Results: First, theachers' thoughts about the transition from ECEC to primary school was noteworthy. Second, the more concern a theacher' had about transition, the higher their learner-centered teaching method. Third, teacher' concern about transition influenced children's school adjustment. Fourth, a teacher's learner-centered teaching method mediated concern about children's transition and school adjustment in the first year and the second year. Conclusion/Implications: According to the results of this study, 1st grade teachers' concern about the transition from ECEC to primary school has been found to be predictors of children's school adjustment.

Various transition elements are used in general for the effective finite element analysis of complicated mechanical structures. In this paper, a solid-to-beam transition finite element, which can b e used for connecting a C1-continuity beam element to a continuum solid element, is proposed. The shape functions of the transition finite element are derived to meet the compatibility condition, and a transition element equation is formulated by the conventional finite element procedure. In order to show the effectiveness and convergence characteristics of the proposed transition element, numerical tests are performed for various examples. As a result of this study, following conclusions are obtained. (1) The proposed transition element, which meets the compatibility of the primary variables, exhibits excellent accuracy. (2) In case of using the proposed transition element, the number of nodes in the finite element model may be considerably reduced and the model construction becomes more convenient. (3) This formulation method can be applied to the usage of higher order elements.
