필자가 참여했던 쌍발복합재사업, 쌍발복합재항공기사업, SB427 민수용헬기사업, T-50 초음속고등훈력기 사업을 통해 복합재료의 항공기 적용사례를 고찰하면서, 쌍발복합재항공기는 실험용항공기(Experimental Aircraft)이지만 국내 최초의 전복합재항공기(All-composites Aircraft)로서 항공기 구조물이 순전히 복합재료만을 이용하여 설계 및 제작이 가능하다는 것을 보여주었고, 복합재료를 적용 시 어떠한 이점이 있는지를 보여준 예가 되고 있다. SB427 민수용헬기사업은 헬리콥터에서 로터 블레이드와 동체 등 기체구조물 대분에 왜 복합재료를 사용해야 효과적인 지를 잘 보여주고 있다. SB427 개발 사업을 통해 얻을 수 있는 또 다른 점은 민수용 항공기의 경우 구축된 복합재료 인증체계에 따라 복합재구조물을 개발해야 되고 그래야만 마케팅에서 신뢰를 얻을 수 있다는 것이다. T-50 항공기는 국내에서 최초로 개발된 초음속기로 미익 부문에 복합재료가 응용되었다. 양산 항공기의 주구조물에 복합재료가 쓰인 예는 T-50이 첫 번째 인데 T-50에서 얻어진 복합재 적용기술은 앞으로 개발될 고급 군용기와 민수용기에 널리 활용될 것으로 기대된다. 본 논문에서는, 국내 개발 항공기에서의 복합재료 적용이라는 특정 주제를 중심으로 개발 이력과 기술적 조망을 통하여, 정부, 연구소, 업체 간의 유기적이고 체계적인 전략이 필요하다고 사료되며, 이러한 전략을 바탕으로 효율적인 항공 산업을 선점해야 할 것이다.

A Meta-analysis refers to a statistical literature synthesis method from the quantitative results of many known empirical studies. We conducted a meta-analysis and review of external factors based on the technology acceptance model for Smartphone-related researches. This study surveyed 106 research papers that established causal relationships in the technology acceptance model published in Korean academic journals during 2008 and 2013. The result of the meta-analysis might be summarized that the playfulness has the highest effect size in the path from external factors to the perceived usefulness, with the effect size(0.536). Also the self efficacy showed the highest effect size(0.626) in the path from external factors to the perceived ease of use. Based on these findings, several theoretical and practical implications were suggested and discussed with the difference from previous researches.

The purpose of this study is to examine main variables of dysfunctional communication, which worsen marital conflicts in terms of marital interaction and to clarify the relative effects of such variables. The subjects were 295 married males and females, and collected data were analyzed using SPSS WIN 23.0 program. The main findings are as follows : First, the tendencies of related variables showed that the levels of spouses' perspective taking and routine marital responsiveness were higher for both males and females, while the levels of irrational belief for marital relations and dysfunctional communication were low. Second, an analysis of spouses' perspective taking, routine marital responsiveness, irrational belief in marital relations and correlations of dysfunctional communication showed that spouses' perspective taking and routine marital responsiveness for both males and females have negative correlations with dysfunctional communication. The higher spouses' perspective taking and routine marital responsiveness, the lower the level of irrational belief related to marital relations and the lower the level of dysfunctional communication. This study clarifies that spouses' perspective taking, routine marital responsiveness and irrational faith for marital relations influence marital dysfuctional communication and has an implication, in that the findings can be used as basic data for seeking methods to solve problems of couples who experience conflicts derived from dysfunctional communication.

The purpose of this study was to investigate developmental tendencies and age-related differences in the relationship between children's cognitive and emotional perspective-taking ability. The subjects were 4-year-old (N=60), 6-year-old (N=60) and 8-year-old (N=60) children. In each group, there were an equal number of boys and girls. Feshbach & Roe's child perspective-taking ability test was modified for this study. The test included four facial expression cards and six different stories inducing three types of emotion: happy, sad and angry. This experiment consisted of a 3 (age) by 3 (emotional stories: happy, sad and angry) factorial design. The dependent measures were two response types: emotional and cognitive perspective-taking ability. The results showed that both cognitive and emotional perspective-taking ability increased with age. Happy emotional perspective-taking ability developed earlier than sad and angry perspective-taking ability. The correlation between cognitive and emotional perspective-taking ability increased with age.

Considering that previous works on safety behavior relatively have not paid adequate attention to the influence of various leadership styles on safety behavior. The current paper investigates the impact of authentic leadership on safety behavior and its intermediating mechanisms. In specific, this paper delves into the mediating effect of job stress, as well as the moderating effect of perspective taking ability of employees in the association between authentic leadership and job stress. The results demonstrated that that authentic leadership has a negative (-) influence on job stress, which has a negative (-) influence on safety behavior. Moreover, job stress mediated the association between authentic leadership and safety behavior. Furthermore, perspective taking moderated the authentic leadership-safety behavior link.

Objectives: The purpose of this study was to investigate the acceptance of family diversity among college students and related variables. Method: Data were collected by a structured questionnaire with 280 students who attended in three universities located in J province. SPSS Statistics Program version 24.0 was used to analyze the collected data. To answer the research questions, descriptive statistics, t-test, F-test, Pearson's correlation analyses, and regression analyses were performed. Results: The major results of the survey were summarized as below. First, the acceptance of family diversity among college students was slightly higher than the middle level(M=12.11). Most students accepted nuclear family as a typical family. More than half of the students accepted single parent families, adaptive families, step families, unmarried mother families, childless couples, homosexual families, elderly women living alone, and families composed of siblings as a family. Second, there was a significant difference by religiosity. Students without religion were higher than their counterparts with religion in a level of family diversity acceptance. Among the individual factors, third, a level of traditional family value had a significant negative effect on a level of family diversity acceptance. And perspective taking had a positive effect on a level of family diversity acceptance. Fourth, among the family factors, parent-child open communication did not affect a level of family diversity acceptance. However, parents' gender egalitarian beliefs had a significant positive effect on a level of family diversity acceptance. Lastly, regarding the relative effects of the personal and family factors, the traditional family value had the largest effect on a level of family diversity acceptance among college students. Conclusions: Base on these results, the implications and limitations of the study were discussed.

While depressives tend to be preoccupied with their own grief and the negative aspects, they might lack the capacity to interact with outside world. With the intention to determine whether depressives might have certain characteristics regarding empathic behavior, as behavior is highly based on responsiveness to others, we examined the relationship between emotional empathy and depression. In addition, we examined the mediating effect of self-criticism on the relationship between emotional empathy and depression. Data was collected from 146 online university students and analyzed using the correlation and multiple regression model. Results showed that perspective taking, which is the cognitive aspect of empathy, was negatively correlated with depression. Concerning the emotional aspects of empathy, both empathic responding and empathic concern were negatively correlated with depression, while personal distress was positively correlated with depression. Regression results, which set the empathy related variables as predicting variables, found perspective taking decreased depression, and personal distress enhanced depression. In addition, personal distress showed significant enhancing effect on depression and was completely mediated by self-criticism. With the result, implications and limitations of this study were discussed.
