The purpose of this study is to investigate mediated effect of spirituality on the relationship between perceived burdensomeness and death anxiety among the elderly. According to the result of this study, it was learned that perceived burdensomeness of aged people has significant correlations with a path of perceived burdensomeness to death anxiety, a path of spirituality to death anxiety and a path of perceived burdensomeness to spirituality. In short, higher perceived burdensomeness results in higher death anxiety, and higher spirituality lowers the death anxiety. This refers that perceived burdensomeness is predictor of death anxiety. In addition, it also indicates that mediated effect of spirituality has significant correlations with both full/partial mediator models - partial mediator model supposes both direct and indirect paths that differ from the way of perceived burdensomeness influences on death anxiety, while full mediator model supposes only indirect path. The result of this study suggests practical proposal to promote the quality of living of the elderly by reducing perceived burdensomeness that stimulates death anxiety and giving opportunity for experiencing spirituality to cope with death anxiety.

The study aimed to investigate the relation between patriarchal family environment and zero-sum beliefs, and the mediating effect of sexism on the relation based on the Instrumental Model of Group Conflict (Esses et al., 1998). This study also examined the moderating effect of gender on the relation between patriarchal family environment and sexism, and the moderated mediating effect of gender through sexism. Participants were 310 first-year college students (234 males and 76 females) in the college of science and engineering, and they completed a survey consisting of patriarchal family environment, sexism, and zero-sum belief. Data were analyzed using SPSS Macro Process, and the results indicated that the relation between patriarchal family environment and zero-sum beliefs was fully mediated by sexism. In addition, the relation between patriarchal family environment and sexism was moderated by gender. Specifically, patriarchal family environment significantly predicted sexism for men, but not for women. Moreover, only for men, sexism mediated the relation between patriarchal family environment and zero-sum beliefs. Therefore, patriarchal family environment could cause sexism which could promote zero-sum beliefs for men.

The purpose of this study is to clarity the effect of job autonomy, innovative work behaviors and perceived organizational support on organizational performance. To attain this goal, mediation analysis, moderation analysis and moderated mediation analysis were performed. 198 valid questionnaires from China Tianjin City's logistics enterprises were analyzed with SPSS Macro program. The results indicated that: (1) perceived organizational support's moderating effect existed in the relationship between job autonomy and innovative work behaviors, (2) innovative behaviors' mediated effect existed in the relationship between job autonomy and organizational performance, (3) perceived organizational support's moderated mediation effect is existing in the relationship between job autonomy, innovative behaviors and organizational performance. That is to say, the strength of the mediated effect decreased along with levels of perceived organizational support: stronger job autonomy relationship when perceived organizational support was weak.

This study aims to investigate the effect of perceived supervisor support(PSS) on employees' in-role and extra-role performance by examining the mediating role of job-based psychological ownership(JBPO). Data were collected from 269 employees from a variety of companies. Both regression analysis and structural equation modeling were used. Previous research has found a positive relationship between PSS and job performance. However, empirical analysis has not yet demonstrated PSS-performance relationships mediated through JBPO. Thus, this study investigated this mediation in predicting in-role and extra-role performance. In the current study, JBPO was found to fully mediate the relationship between PSS and in-role performance and to partially mediate the relationship between PSS and extra-role performance. Future discussions and practical implications are discussed.

This study aims to examine how subjective class perception of children from single-parent families affects suicidal thoughts and to verify the mediated effects of depression and subjective health perception. To this end, the analysis data used the 2020 Korean Children and Youth Human Rights Survey conducted by the Korea Youth Policy Institute, and 618 children from single-parent families who responded to the survey were selected and analyzed as study subjects. As a result of the analysis, first, it was found that the higher the subjective class perception, the lower the suicidal impulse. Second, depression was found to be completely mediated in the relationship between subjective class perception and suicide impulse. Third, subjective health awareness was found to be completely mediated in the relationship between subjective class perception and suicidal thoughts. Based on these research results, we proposed policy and practical measures to reduce suicidal impulses according to the subjective class perception of children of single-parent families.

This study aimed to confirm the positive impact of individual entrepreneurial orientation on entrepreneurial intentions and to investigate whether cognitive competency and social awareness of entrepreneurs serve as mediating variables in the relationship between individual entrepreneurial orientation and entrepreneurial intentions. The results of this study are as follows: Individual entrepreneurial orientation positively influenced entrepreneurial intentions, cognitive competency, and social awareness of entrepreneurs. Moreover, it was found that higher levels of cognitive competency and social awareness led to higher entrepreneurial intentions. Additionally, it was demonstrated that cognitive competency and social awareness of entrepreneurs had parallel mediating effects in the relationship between individual entrepreneurial orientation and entrepreneurial intentions. Based on these findings, this study provides theoretical foundations for research on the relationship between individual entrepreneurial orientation and entrepreneurial intentions, which have been relatively underexplored. Furthermore, by identifying cognitive competency and social awareness as mediating variables, this study opens avenues for academic expansion. Finally, the findings of this study can serve as practical groundwork related to individual entrepreneurial orientation.

일반적으로 강우-유출모형은 lumped model과 distributed model로 크게 구분될 수 있으며, 우리나라에서는 이중 비교적 부족한 자료를 이용하여도 개략적 모의가 가능한 전자를 널리 사용하고 있다. 본 연구에서는 이러한 모형들의 매개변수를 보정하는 방법에 관해 연구하였다. 일반적으로 모형의 보정 방법에는 크게 시행오차에 의한 수동보정(manual calibration) 방법과 최적화 기법에 의한 자동보정(automatic calibration) 방법으로 나눌 수 있다. 수동보정 방법은 모형 수행결과를 수문곡선의 시각적 비교에 의해 관측치와 비교하여 모형 운영자의 주관적인 판단하에 조정하는 기법이며, 자동보정 방법은 최적화 기법을 이용8하여 특정한 산정기준(estimation criteria)을 최대 또는 최소화시켜 모형의 매개변수를 결정하는 방법이다. 이러한 최적화기법은 일반적으로 직접탐색법과 경사법으로 구분할 수 있다. 경사법은 수렴속도가 빠르지만 편미분에 의해 방향을 찾아가는 방법으로 편도함수가 필요하므로 수문모형에는 적용하기가 힘들므로 적합하지 않다. 그러나, 보다 많은 컴퓨터 수행시간을 필요로 하는 직접탐색법의 경우 수렴속도는 느리지만, 편도함수를 필요치 않으므로 수문모형의 최적화 기법으로 적합하다고 할 수 있다. 직접탐색법에는 simplex-search 법, 패턴인식(pattern-search)법, rotating-direction 법, brent 법 등이 있으며, 본 연구에서는 직접탐색법의 일종인 패턴인식(pattern -search)법을 이용하여 매개변수 최적화 과정을 모의하였다. 이러한 매개변수 보정모형을 구성한 후 이를 가장 보편적으로 사용되고 있는 유출모형인 각종 단위도법들을 결합하는 모형을 구성하였다. 또한 구성된 모형을 시범유역에 적용하여 나온 결과를 HEC-1에서 적용되고 있는 단일변량 증감법과 같은 최적화 기법을 이용한 결과와 비교·분석을 실시하였다. 본 모형을 활용하여 강우-유출 모형의 매개변수를 지속적으로 산정하고 일반화할 경우 임의의 유역의 수문기상학적 특성에 부합한 매개변수를 정량화 시킬 수 있었다.

한 미디어를 다른 미디어에서 표상하는 것을 재매개 remediation (이재현, 2006)라고 한다. 보통 재매개는 원 소스 멀티 유즈 혹은 재목적화 repurposing로 알려져 있다. 한 미디어가 다른 미디어를 통해 표상된다는 사실은 한가지 컨텐츠를 다양한 창구 혹은 채널을 통해 내보냄으로써 해당 컨텐츠의 가치를 극대화한다는 경영학적 의미뿐만 아니라, 미학적 사회학적 의미를 가진다. 특정한 미디어를 통해 보여지는 컨텐츠가 이질적인 다른 미디어를 통해 표상되면, 컨텐츠 뿐만 아니라 표상되는 미디어도 쉽게 인식하게 되면서 미학적 의미를 갖는다. 가령 액자 속에 들어있는 풍경화를 보는 순간, 액자라는 창을 넘어서 그림이 표상하는 풍경을 보려고 하지만, 액자 속의 퐁경화를 텔레비전을 통해 보게 되면, 시청자는 그림을 둘러싼 액자 혹은 그 그림이 위치한 미술관을 인식하기 마련이다. 또한 새롭게 등장하는 미디어와 그 종사자는 기존 미디어 혹은 종사자들의 사회적 지위를 표상하면서 기존 미디어의 지위를 이어받으려고 하면서 사회적 의미를 갖는다. 컴퓨터 게임이라는 미디어가 텔레비전을 통해 방송되는 e-sports는 디지털 컨텐츠의 전형적 재매개의 예가 될 수 있다. e-sports중계는 컴퓨터 게임 화면만을 보여주지 않는다. 게이머의 표정, 게임의 제반 정보를 나타내는 게임 화면의 세부 창들, 관중들의 반응, 해설자의 해설, 리플레이 화면 등을 동시 혹은 선형적으로 보여줌으로써, 시청자로 하여금 끊임없이 컴퓨터 게임이라는 미디어를 인식하게 한다. 또한 e-sports는 이름에서도 드러나듯이, sports의 사회적 지위를 표상한다. e-sports 플레이어들이 선수로 불리고, 이들이 프로 게임단을 조직해 활동한다. e-sports(스타크래프트의 경우)는 상설 경기장에서, 종종 체육관에서 대규모 관중들 앞에서 보여짐으로써 기존 sports 경기를 표상한다. 재매개는 새로운 미디어가 등장하면서 자연스럽게 취하는 전략이다. 새로운 미디어가 쏟아지는 디지털 미디어 시대, e-sports의 재매개 전략을 살펴봄으로써 새로운 미디어가 미학적, 사회적으로 자리잡을 수 있는 함의를 얻을 수 있다.

The present study examined how the psychological well-being of young adults was affected by the perceived parental rearing attitudes and how self-concept clarity and the perceptions of emerging adulthood mediated this causal relationship based on Arnett's the theory of emerging adulthood. We specially focused on affectionate or rejective types of perceived parental rearing attitudes and possibility or instability perceptions of emerging adulthood. We performed survey research with 358 university students from six universities located in Seoul, and other cities in South Korea and analyzed collected data using SPSS 25.0 and SPSS Macro. As a result, we found correlational relationships between psychological well-being of emerging adulthood and other variables. Also, we found the mediating effect of the self-concept clarity in the relationship between the psychological well-being and the perceived parental attitudes: affectionate, rejective. However, we only found the mediating effect of the perceived possibility perception of emerging adulthood was significant in the relationship between the psychological well-being and affectionate parental rearing attitudes. Finally, we found a sequential mediation effect that the self-concept clarity and then perceived instability perception of emerging adulthood affected in the relationship between psychological well-being and rejective parental rearing attitudes of emerging adulthood. Based on results, implications and suggestions for counseling service and psychological education for university students faced emerging adulthood were discussed.

Purpose: The purpose of this study was to explore whether or not there is a relationship between doctor's awareness of clinical nutrition service and needs for a clinical dietitian. Methods: A cross-sectional survey design was used. The research was carried out by using questionnaires that had been specifically designed for the study. The research was conducted from September to October, 2013 for 311 doctors at 43 hospitals (with over 400 beds). Frequency analysis, factor analysis, reliability analysis, confirmatory factor analysis, and bootstrapping analysis were conducted using SPSS 21.0. Results: 'Implementation of clinical nutritional service' (p < 0.001) and 'usefulness on clinical nutrition service' (p < 0.001) were found to be correlated with 'importance of clinical nutrition service' as an independent variable. The correlation between 'importance of clinical nutrition service' as a mediating variable and 'needs for clinical dietitian' as a dependent variable was also confirmed (p < 0.001). The results of the bootstrapping test showed that the mediating effect of 'importance of clinical nutrition service' was significant. The indirect effect value between 'implementation of clinical nutrition service' and 'needs for clinical dietitian' was 0.040, indirect effect value between 'usefulness on clinical nutrition service' and 'needs for clinical dietitian' was 0.095. Conclusion: The frequency of providing clinical nutritional services, the quality of clinical nutritional services, and the degree of implementation of clinical nutritional services were found to be important for positive perception of clinical nutrition services by doctors. Therefore, proper provision of clinical nutrition services and effective therapeutic effects will be continuously highlighted, which will increase the awareness of the physician and ultimately increase the demand for clinical nutrition service.
