Instagram, a photo and image centered social networking service, has received increasing attention these days, from scholars and practitioners. However, little is known about the social and psychological factors that lead consumers to use this service. To provide a baseline understanding on Instagram users, the current study was conducted to discover perfectionistic self-presentation tendency expressed by the Instagram users and explore the relationships between identified perfectionistic self-presentation and intention to use Instagram variables with 250 participants. In addition, this study tried to determine the moderator effect of self-efficacy and self-construal. A comprehensive survey was directed and a total of 380 participants were recruited to verify anticipated hypotheses and research questions. The research results suggest that perfectionistic self-presentation has five sub factors: others conscious self-presentation, subjective self-presentation, environmental adaptation self-presentation, self-expansion self-presentation, and social self-presentation. The implications of this research findings are discussed.

Social media such as Twitter and Facebook have become popular. In the age of social media, many people have become more active online. For example, about half of all global active Internet users are on Facebook (Perry 2012). Personal branding is a very important strategy to build on an individual's strengths, and this kind of branding is expected to contribute to self-actualization. Therefore, the presence of mentors who advise users to discover their own strong points for self-actualization is necessary. In this paper, we propose a personal branding support service, Mentors, which connects mentors and mentees. The core concept is: "Everyone has the face of both a mentor and mentee." The key function is sharing stages of self-analysis in human life design: Determining value, creating a mission, and forming a strategy. From this function, a good match between a mentor and mentee can be found. The program aims to improve human life by understanding the client's strengths and using social media effectively. Future work includes launching Mentors and evaluating its service.

The program for overcoming shyness consisted of four step-by-step parts, understanding shyness, overcoming anxiety, improving self-esteem, and promoting self-assertion. Participants were 6 boys and 10 girls from three kindergarten classes. The two gender groups were randomly assigned to either the experimental or the control group. The experimental group participated in the program for 50 minutes per day twice a week for 12 sessions, and the control group received no treatment. Eight non-shy children also joined the program in the ninth and tenth sessions. Findings indicated that shyness in the experimental group decreased significantly while the control group maintained previous levels of shyness, implying that early intervention programs have potential effectiveness for reducing shyness in young children.

Purpose: The purpose of the study is to confirm the effect of ACLS program using simulations and understanding self-efficacy, practice satisfaction, learning attitude, and interest in ACLS after theory classes and simulation-based practice. Methods: A non-equivalent simulation-based practice post test design was used. The participants were 28 paramedic students. The students participated in simulation-based practice for 3 weeks and conventional instruction class for 12 weeks. Results: The students showed higher level of self-efficacy(p=.043), practice satisfaction(p<.001) and learning attitude(p=.003) compared to the conventional lecture students. Conclusion: Level of self-efficacy after simulation-based practice for ACLS was higher than that of self-efficacy after conventional instruction classes. Level of practice satisfaction was also higher. Academic achievement after simulation-based practice was higher than that in conventional instruction classes.

Purpose: The purpose of this study was to examine gender differences in eating disorders and in several risk factors; body dissatisfaction, perfectionism, self-esteem, and depression. Method: The data were collected from 423 students in grades 5 or 6 (230 male and 193 female) in this cross-sectional study. For data analysis, descriptive statistics, t-test, Pearson correlation coefficient, and stepwise multiple regression were used with the SPSS/PC ver 12.0 program. Results: Girls experienced more symptoms of eating disorders, body dissatisfaction, and depression than boys. There were also gender differences in risk factors. For girls, depression, socially-prescribed perfectionism, and body dissatisfaction were related to eating disorder behaviors, whereas for boys, depression, self-oriented perfectionism, body dissatisfaction, and self-esteem were related to eating disorder behaviors. Conclusions: The results of the present study indicate that risk factors for eating disorders for boys and girls may be different, and these differences have implications for understanding the etiology of eating disorders and should be considered in planning possible nursing interventions.

This paper investigates the possibility of a strategy for an automatic full recover of a structural component undergoing loading-unloading (fatigue) cycles: full recover means here that no replacement is required at the end of the mission. The goal is to obtain a material capable of self healing earlier before the damage becomes irreversible. Attention is focused on metallic materials, and in particular on shape memory alloys, for which the recovering policy just relies on thermal treatments. The results of several fatigue tests are first reported to acquire a deep understanding of the physical process. Then, for cycles of constant amplitude, the self-healing objective is achieved by mounting, on the structural component of interest, a suitable microcontroller. Its input, from suitable sensors, covers the current stress and strain in the alloy. The microcontroller elaborates from the input the value of a decisional parameter and activates the thermal process when a threshold is overcome.

This study examined the applicability of the transtheoretical model(TTM) to understanding exercise behavior of early adulthood. A cross-sectional study was conducted and data wee collected from 1618 adults aged from 20 to 39 through internet survey. Major conclusions wee as follows: 1. Stage distribution for exercise behavior was 15.6%, 26%, 25%, 19%, 14.4% for precentemplation, contemplation, preparation, action, maintenance stages, respectively. 2. Behavioral processes were more frequently utilized than cognitive processes for action and maintenance stage. 3. Self-reevaluation, social liberation and reinforcement were frequently used in precontemplation, contemplation and preparation stages. Self-reevaluation, reinforcement, self-liberation were frequently used in action and maintenance stages. 4. Pros of exercise behavior began to be higher than cons of exercise behavior from the actions stage and continued to increase to maintenance stage. 5. Self-efficacy was higher in action stage than precontemplation, contemplation and preparation stages and the highest in maintenance stage.

Predicting fracture properties requires an understanding of structural failure behaviour in relation to specimen type, dimension, and notch length. Facture properties are evaluated using various testing methods, wedge splitting test being one of them. The wedge splitting test was numerically modelled three dimensionally using the finite element method on self compacting concrete specimens with varied specimen and notch depths in the current work. The load - Crack mouth opening displacement curves and the angle of rotation with respect to notch opening till failure are used to assess the fracture properties. Furthermore, based on the simulation results, failure curve was built to forecast the fracture behaviour of self-compacting concrete. The fracture failure curve revealed that the failure was quasi-brittle in character, conforming to non-linear elastic properties for all specimen depth and notch depth combinations.
