Purpose: This study was performed to analyze effects of the power and empowerment on job satisfaction and organizational commitment. This study was based on the Kanter's theory of organizational empowerment. Method: A predictive, non-experimental design was used to test the model in a sample of 688 nurses working in 7 university hospitals that have over 500 beds in Seoul, Kyunggi and Kangwon provinces. The data were collected from December, 2003 to January, 2004. It was analyzed with descriptive statistics and Pearson correlation of SPSS and with path analysis of LISREL. Result: The formal and informal power had direct effects on empowerment. Formal power also had direct effects on informal power. Empowerment had direct effects on job satisfaction and organizational commitment. Organizational commitment had direct effects on job satisfaction. There was positive effects in all of the variables. Conclusion: The positive changes show on personal behaviors and attitudes when the nurses who have formal and informal power are empowered.

The study examined whether informal and formal social participations may mediate the association between widowhood and depressive symptoms, and whether gender may moderate the mediated associations. The data consisted of men and women 65+ who participated in the $3^{rd}$ wave of the Koran Longitudinal Study of Aging (KLoSA ; N = 4,146). Findings suggest that first, widowed older adults experienced significantly higer levels of depressive symptoms compared to their married counterparts. At the same time, the widowed individuals also reported more frequent contacts with family, friends, and neighbors (informal social participation), which contributed to narrowing the depression gap between widowed and married. Second, gender moderated the mediated association such that the mediating effect of informal social participation was significant only for older widowed women. Further, no mediating effect was found of formal social participation (participation in social, leisure, religious groups) for widowed and married regardless of gender. Previous studies indicated that social participation may be an important mediating factor that attenuates the effect of widowhood on depressive symptoms. Building on existing research, the present study highlighted theoretical rationales for potential gender differences in the way social participation may mediate the widowhood-depression linkage and evaluated statistically whether gender may moderate the mediated association.

In AI image generation tools, most general users must use an effective prompt to craft queries or statements to elicit the desired response (image, result) from the AI model. But we are software engineers who focus on software processes. At the process's early stage, we use informal and formal requirement specifications. At this time, we adapt the natural language approach into requirement engineering and toon engineering. Most Generative AI tools do not produce the same image in the same query. The reason is that the same data asset is not used for the same query. To solve this problem, we intend to use informal requirement engineering and linguistics to create a toon. Therefore, we propose a sequence diagram and image generation mechanism by analyzing and applying key objects and attributes as an informal natural language requirement analysis. Identify morpheme and semantic roles by analyzing natural language through linguistic methods. Based on the analysis results, a sequence diagram and an image are generated through the diagram. We expect consistent image generation using the same image element asset through the proposed mechanism.

다양한 자료를 수집, 정리 및 해석하는 통계의 주요 과정에서 수집된 자료를 올바르게 해석하기 위해서는 자료의 요약이 중요하다. 대푯값은 통계 집단의 변량 전체를 대표하여 그 자료 전체의 특징을 하나의 수로 나타낸 값으로 자료를 조직하고 요약하기 위하여 사용된다. 대푯값에는 여러 가지 형태가 있으나, 우리나라 초등학교 수학과 교육과정에서는 대푯값으로 평균만을 다루고 있다. 따라서 본 연구에서는 초등학교 5학년 학생들이 평균 단원을 학습하기 전 대푯값에 대하여 갖는 비형식적 지식 유형을 알아보고, 평균 단원을 학습한 후와 비교하여 대푯값에 대한 지식의 변화를 살펴봄으로써 학교 수학에서 대푯값 지도에 대한 시사점을 제공하고자 하였다. 그 결과 형식적인 학습을 하기 전 학생들이 대푯값에 대해 풍부한 지식을 가지고 있었고, 이러한 비형식적 지식이 형식화된 개념 유형과 유사함을 알 수 있었다. 초등학생의 대푯값에 대한 비형식적 유형을 살펴보는 것은 초등학교에서 다루어야 하는 대푯값 개념 및 지도 방법에 대하여 시사점을 줄 수 있으며, 중·고등학교에서 대푯값 개념의 형식화를 위한 학습에 도움을 줄 수 있을 것이다.

비공식적 환경에서의 과학 교육이 매우 중요함에도 불구하고 비형식 과학교육(ISL)과 그 영향에 대한 경향 분석 연구가 부족한 것이 현실이다. 이에 본 논문의 목적은 ISL의 교육적 효과와 활용 방안에 대해 알아보고, 향후 ISL 연구 방향에 대한 지침을 주는데 있다. 이 연구는 2010년부터 2019년까지 발표된 특정 ISL 관련 논문을 분류하고, 비형식 교육의 효과 측정에 사용되는 GLO의 각 요소와 비교 분석하였다. 분석된 자료는 SPSS, Chi-Square를 통해 부분별로 적합도를 확인했다. 결론적으로 연구자들은 'GLO'의 5가지 성과지표 중 '지식과 이해'와 '태도 및 가치'를 추구하기 위해 ISL을 활용하고 있는 것으로 나타났다. 반면에 '기술'과 '즐거움, 영감 및 창의성'에는 가장 적은 기대를 하는 것으로 나타나서, 향후 이러한 부분에서의 보완이 요구된다. 또한 이 연구를 통해 다양한 교육 종사자들에게 비형식 과학교육 관련 프로그램 개발과 향후 연구를 위한 방향을 제시하고자 한다.

The ultimate goal of environment education plays an important role in forming knowledge, skill, attitude and a point of value along with sustainable development in the regions. Recently, however, environment education is comparatively despised due to college-entrance-exam-focused education policy. Ironically, environment education is more actively implemented at informal institutes rather than formal ones. Environment education at schools is based on the school curriculum, but at informal educational institutes enjoy much more freedom in choosing learners, places and programs. Among them, the place is one of the most important factors of environment education. Therefore, in order to maximize the goal of environment education in this study, a specified program was developed and applied to a certain place to investigate its features and effects. Also the program was checked if it reflexes the environment education goal by using environment education program analysis frame. The results are as follows; according to the analysis of the program, the program was most effective for the two goals of offering hands-on experience and presenting motivations. The second most effective result of the program lied in the goal of knowledge, functions, value and attitude. And the teachers who used this program concluded that, when the program was applied to unmanned islands, offered stronger motivation due to their natural surroundings. Furthermore, direct experience is recommended because it can give us better conditions to collect data and to enhance interpretation ability.

The purpose of this study was to empirically examine the effects of salespeople's self-determination, shared value; and communication satisfaction on their job satisfaction, organizational commitment, and turnover intention in a fashion company. Questionnaires were administered to 475 salespeople who worked in fashion shop at the time of the study. The data was analyzed via factor analysis, correlation analysis, and a structural equation model. The results indicated that self-determination was extracted as autonomy, competence, and relatedness. Only the relatedness of self-determination factors was positively correlated with formal and informal communication satisfaction. In addition, recognizing hared value was positively correlated with formal and informal communication satisfaction; whereas, the practice of shared value was positively correlated with formal, but not informal communication satisfaction. Formal communication satisfaction was significantly correlated with job satisfaction and organizational commitment. Conversely, informal communication satisfaction was significantly correlated with job satisfaction, but was not related to organizational commitment. Finally, job satisfaction was significantly correlated with organizational commitment and negatively correlated with turnover intention. Moreover, organizational commitment was negatively correlated with turnover intention. The implications of this research for human resources management within fashion companies are discussed in the concluding section of this paper.

A total of 4,323,781 records for informal 16 primary linear descriptive traits of dairy cows in Holstein breed from 1988 to 2007 in USA were analyzed to estimate adjustment factors for lactation number and stage. While all factors in the model were highly significant (P < 0.01), major influences on linear type traits were due to lactation number and stage. The frequencies of lactation number 1 through 6 were 58.6, 22.0, 11.8, 4.8, 2.1, and 0.8%, respectively. Further, the frequencies of lactation stage were 0.7, 76.9, 15.3, 4.9, and 2.1%, respectively, for springing, early, medium, late, and dry. To adjust 16 linear traits (stature, dairy form, strength, body depth, rump width, rump angle, legs rear view, leg set, foot angle, fore udder, rear udder height, rear udder width, udder support, udder depth, and front teat placement), additive and multiplicative adjustment factors of lactation number (lactations 2 to 4) and stage (springing, medium, late and dry) were estimated with the solutions in the generalized linear model, assigning lactation 1 and stage early as base class. Additive adjustment factors of lactation number ranged from -1.23 to 2.908, while multiplicative factors ranged from 0.853 to 2.207. Further, additive and multiplicative adjustment factors for lactation stage ranged from -0.668 to 0.785, and from 0.891 to 1.154. Application of adjustment factors to 20 randomly sampled sub-data sets produced the results that additive adjustment factors for both lactation number and stage reduced more mean square of lactation number and stage over 16 linear traits than any combination of adjustments, and leaded additive adjustment factors for both lactation number and stage as a choice of methods for adjustment of informal 16 primary linear type traits collected by classifiers of AI studs.
