Despite the important role of the transformational leadership and Creative Climate to achieve firms' sustainable competitive advantage, there has been limited empirical studies linking the transformational leadership and creative climate in employee's innovative performance. This study investigated the impact of transformational leadership on innovative performance based on employees of R&D department in IT services. This paper also investigated the mediating role of creative climate and moderating role of employee's innovative tendency in this relationship. Main findings of our empirical analysis are as follows. While the relationships between transformational leadership and innovative performance was positively associated, creative climate had positive effect on innovative performance. As expected, we also found that the creative climate had positively mediated the relationship between transformational leadership and innovative performance. Also, the innovative tendency has statistically significant moderating effect on this relationship. Based on the findings, we have suggested theoretical and practical implications while future research directions with limitations of the research are discussed.

In order to analyze the factors influencing career maturity of general high school students, this study verified the moderated mediating effect of career exploration efficacy by the frequency of conversation with parents in the process of self-awareness and class attitude affecting career maturity. For the study of the second year of general high school, the results of verifying the moderated mediating effect using SPSS 22 and Model 7 of PROCESS macro from the results of the first year survey of the Korea Education and Employment Panel (KEEP) II are as follows. First, positive self-awareness and class attitude had a positive effect on career maturity. Second, career exploration efficacy mediates self-awareness, class attitude, and career maturity. Third, in the relationship between self-awareness and career maturity, there is no moderated mediating effect on career exploration efficacy by the frequency of conversation with parents. Fourth, in the relationship between class attitude and career maturity, a confrontation-moderated mediating effect on career exploration efficacy by conversation frequency with parents appears. Based on these studies, implications and future tasks for career maturity of general high school students were proposed.

This study was conducted to examine the moderated mediation effect of self-esteem through internet overdependence on the effect of academic stress on depression and anxiety. Surveys were conducted as part of the 13th wave of the Korea Welfare Panel Study. The survey included academic stress, internet overdependence, depression and anxiety, and self-esteem scales. A total of 383 middle school students completed surveys. Data was analyzed using SPSS 21.0 and SPSS PROCESS Macro. There were three major results. First, internet overdependence partially mediation the effect of academic stress on depression and anxiety. Second, self-esteem moderated the relationship between internet overdependence and depression and anxiety. Third, self-esteem also moderated the mediating effect of academic stress on depression and anxiety through internet overdependence. These results indicate that self-esteem is a protective factor against the negative effects of internet overdependence on mental health and of academic stress on depression and anxiety in middle school students. This paper discusses the implications of these results, this study's limitations, and suggestions for future studies.

The purpose of this study is to investigate the effects of systems thinking on high school students' self-regulatory efficacy and self-confidence that constitute science self-efficacy. We set self-regulatory efficacy as a factor of students' systems thinking affects their self-confidence on science through self-regulatory efficacy. A total of 210 students were sampled from general high schools and 188 valid cases were analyzed. The instrument has 39 items that consist of 20 items measuring systems thinking and 19 items of science self-efficacy. The result of the exploratory factor analysis indicated that 20 items for systems thinking, 8 items for self-regulatory efficacy, 4 items for self-confidence are reasonable. Testing the goodness of fit of a structural equation model, it turn out to be appropriate (${\chi}^2$=344.498, df=242, TLI= .921, RMSEA= .044) using 24 items (mental model, personal mastery, systems analysis, self-regulatory efficacy, and self-confidence were constructed). In addition, the mental model, which is one factor of systems thinking, is mediated by self-regulatory efficacy that affects self-confidence directly and/or indirectly. The results suggest that systems thinking affects science self-efficacy directly and indirectly. Utilizing systems thinking in science education can produce a theoretical basis in improving students' confidence and self-efficacy about science.

This study tried to understand the mediating role of stress perception and the moderating role of mindfulness in the process of psychological alienation affecting college students' smartphone addiction tendency. Two hundred seventeen university students from Chungcheongnam-do answered the questionnaire. The research model was analyzed with model 7 of Hayes' PROCESS Macro 4.0. When synthesizing analysis results, feelings of alienation mediate stress responses or directly influence smartphone addiction tendencies. At this time, people with high levels of mindfulness tended to lower their smartphone addiction tendencies by alleviating their stress response compared to those with a low level of mindfulness. The implication of this study is that it revealed the psychological process that causes alienation to induce smartphone addiction tendency through stress responses, and that mindfulness plays a role in alleviating stress response and lowering smartphone addiction tendency. In the future, it is necessary to apply the model of this study to people diagnosed with smartphone addiction.

해마 뉴런의 시냅스에서 발생하는 전류는 후시냅스의 생화학적 반응을 통해 다음 뉴런으로 전달된다. 즉, 시냅스는 정보를 전달하는 매개로서 전시냅스에서 입력된 정보에 의거하여 후시냅스로 보내는 전류량을 조절하게 된다. 본 논문에서 제안하는 시냅스 기전 신경망 모델은 기존의 신경망과는 달리 시냅스에서 일어나는 반응-확산(reaction-diffusion) 모델에 의하여 입력과 출력의 관계를 결정한다. 제안된 신경망을 분류 문제에 적용한 결과 은닉 뉴런층 없이도 좋은 성능을 보였으며, 이 신경망은 앞으로 뇌에서의 생화학적 뉴런 학습 양상을 연구하는 모델로 사용될 수 있다.

본 연구에서는 예비창업자의 심리적 특성 중 실패에 대한 두려움이 계획된 행동모델의 변수들을 매개로 하여 미래의 창업의도에 미치는 영향을 살펴보았다. 창업의도와 관련된 기존의 선행연구들은 많이 있었으나 주로 창업성공에 영향을 미치는 요인, 창업의도를 높이는 요인을 중심으로 연구가 진행되고 있음을 발견하였다. 이에 본 연구에서는 실패에 대한 두려움이 기업가적 활동을 수행함에 있어 본질적으로 내재되어 있는 요인임에도 불구하고 상대적으로 연구에서는 소홀하게 다루어졌던 것에 주목하여 실패에 대한 두려움을 측정하는 PFAI(Performances Failure Appraisal Inventory) 척도를 사용, 예비창업자의 실패에 대한 두려움이 창업의도에 미치는 영향을 창업에 대한 태도, 주관적 규범, 행동의도 등을 매개로 하여 실증하였다. 또한 실패에 대한 두려움을 상쇄시키는 역할로써 창업교육의 효과성을 살펴보았다. 이를 위해 서울 시내 대학생들을 중심으로 구조화된 설문지를 이용하여 자료를 수집 하였고, 수집된 자료는 AMOS 18.0 프로그램을 사용하여 분석하였다. 연구결과는 다음과 같다. 첫째, 실패에 대한 두려움은 창업에 대한 태도와 주관적 규범에 각각 부(-)의 영향을 미쳤다. 둘째, 창업에 대한 태도와 주관적 규범은 창업의도에 정(+)의 영향을 미치는 것으로 나타나 선행연구와 일치하는 결과를 보였다. 셋째, 실패에 대한 두려움은 창업의도에 직접적인 영향을 미치기보다는 계획된 행동모델의 구성요소인 창업에 대한 태도와 주관적 규범을 매개로 하여 각각 영향을 미쳤다. 넷째, 창업교육이 실패에 대한 두려움과 창업의도와의 관계를 조절하는지 분석한 결과 창업교육을 수강한 집단에게서 실패에 대한 두려움이 창업에 대한 태도와 주관적 규범에 미치는 부정적인 영향이 더 크게 나타났다.

Systematic studies have been rarely conducted on the acceptance of big data technology despite the technology drawing much attention from academia, industry and general public. With big data technology still being in the infant stage in Korea, a study model was constructed in this paper by integrating the innovation diffusion theory and the task technology fit theory with this technology acceptance model (TAM) as the central framework to make big data technology more readily acceptable in the country, and the aim of making big data technology readily acceptable was expanded as the moderator variable of the TAM. The results of this study showed that "subjective norm" and "task technology fit" showed the most significant effect as the exogenous variables of the TAM. In addition, the "innovative characteristic of the organization" was the significant exogenous variable affecting the intention to accept big data technology to those "technology utilizers" that try to come up with new services or products that are technology-based; however, "subjective norm" was the rather significant factor affecting those simple "technology users". Finally, a significant difference was seen in the verification of mediation effect.

The purpose of this study was to identify psychological factors that influence psychological well-being in middle-aged adults(40-65 years old). In particular, we aimed to determine whether mentalization, the ability to clarify one's internal experiences, and adaptive cognitive emotional regulation have a dual mediating effect on the relationship between insecure adult attachment(anxious, avoidant) and psychological well-being in middle-aged adults. To address the research questions, structural equation modeling was conducted using Jamovi 2.2.5 statistical program to analyze survey responses from 317 middle-aged adults (117 males and 200 females) who voluntarily participated through mobile and offline surveys. The results of the study are as follows. First, in the structural equation model, the simple mediating effect of mentalization on the relationship between insecure adult attachment(anxious and avoidant) and psychological well-being in middle-aged adults was not significant. Second, the simple mediating effect of adaptive cognitive emotion regulation on the relationship between insecure adult attachment and psychological well-being was significant only for anxious attachment. Third, the relationship between insecure adult attachment and psychological well-being was fully mediated by mentalization and adaptive cognitive emotion regulation for anxious attachment, but partially mediated for avoidant attachment. These findings help provide a theoretical framework for developing programs to increase psychological well-being among middle-aged adults, a growing segment of society.

This study identified the relationship between deliberate rumination of adults who experienced traumas and post-traumatic growth, and examined the mediating model of meaning of life moderated by trauma intensity on deliberate rumination and post-traumatic growth. Participants were 318 male and female adults who experienced traumas. The moderated mediating effect was analysed with PROCESS Macro 3.5 Model 7. Results revealed that deliberate rumination of adults who experienced traumas was positively correlated with trauma intensity, meaning of life, and post-traumatic growth, while meaning of life was positively correlated with post-traumatic growth. In a moderated mediating model for post-traumatic growth, there was significant interaction effect of deliberate rumination and trauma intensity; conditionally indirect effect of deliberate rumination was only significant for whose trauma intensity were high. These findings suggest that adults who did deliberate rumination are more likely to experience post-traumatic growth with finding meaning of life. And, the moderating effect suggests that this influence is only with higher levels of trauma intensity. In conclusion, deliberate rumination of severe traumatic event may lead to post-traumatic growth, and it can be helpful to experience the meaning of life in the process.
