This study focused on the relationships among teachers'playfulness, teachers'positive play beliefs, teaching efficacy on play and teacher's strategies of problem behavior guidance, and especially the mediating effects of teaching efficacy on children's play. Subjects were 151 early childhood teachers in Seoul and Chungcheungnam-do. The collected data were analyzed using simple regression, hierarchical multiple regression and the Sobel test. The main results of this study were as follows. First, teachers' playfulness and teachers'positive play beliefs had a positive influence on their proactive, positive reactive strategies of problem behaviors. On the other hand, teachers' positive play beliefs had a negative influence on their negative reactive strategies of problem behaviors. Second, teachers' playfulness and teachers'positive play beliefs had a positive influence on their teaching efficacy on play. Finally, the effects of teachers' playfulness on their proactive, positive reactive strategies of problem behaviors of preschoolers were totally mediated by their teaching efficacy on play.

This study investigated how general blended learning strategies and flipped-learning instructional strategy affect college students' social presence and group cohesion. The main results of this study were summarized as follows. First, the group of flipped-learning instructional strategy was more effective in college students' social presence than general blended learning. Second, it was found that groups using flipped-learning instruction strategy had more positive effects on improving group cohesion among college students than those using the general blended learning instructional strategy. The results of this study can influence the identification and verification of the main components to be considered when using flipped-learning instruction strategy in blended learning environment. The results of this study can influence the identification and verification of the main components to be considered when using flipped-learning instruction strategy in blended learning environment.

고객상담센터 또는 Call Center(콜센터)는 기업조직상 고객과의 최일선 접점에 위치하여 고객만족 경영의 중추적인 역할인 대고객 communication이라는 막중한 임무를 담당함에도 불구하고, 우리나라학계 뿐만이 아니라, 미국의 학계에서도 연구가 빈약한 분야이기 때문에 연구의 필요성이 강력히 요청되는 분야이다. 2) 본 연구는 지금까지 고객의 요구에 대응하기 위하여 임기응변적으로 설계 및 운영하여 온 우리나라의 고객상담센터, 특히, 전화고객상담 센터(Call Center)의 효율향상을 위한 경영개선 노력을 위한 “리엔지니어링 전략”에 관한 탐색적 연구다. 연구방법으로서는 문헌(주로 미국) 및 미국의 call center 실태조사 자료를 우리나라의 자료와 비교하여 리엔지니어링의 대상을 탐색하는, 소위 선진지역과의 벤치마킹(benchmarking) 방법을 택하였다. 구체적으로, 본 연구는 콜센터의 효율적인 운영을 위한 주요 구성요소인 인적요소 및 기술적 요소 등을 연구한다. 본 연구는 콜센터 리엔지니어링분야의 문헌을 체계적으로 고찰하였으며 특히 미국의 콜센터와 직접적인(head-to-head) 비교를 처음 시도했다는 점에서 이 분야의 향후 연구에 공헌을 할 수 있다고 믿는다. 또한 이연구의 결과는 우리나라 콜센터 관련 기업실무자들이 리엔지니어링을 추진하는데 중요한 참고자료로 이용할 수 있으며 특히, 관련 software 및 hardware의 설계와 개발에 중요한 방향제시를 할 수 있으리라 기대한다.

In this paper, adaptive evolutionary algorithm(AEA) is proposed, which uses both genetic algorithm(GA) with good global search capability and evolution strategy(ES) with good local search capability in an adaptive manner, when population evolves to the next generation. In the reproduction procedure, proportion of the population for GA and ES is adaptively determined according to their fitness. The AEA is used to design membership functions and scaling factors of the fuzzy logic controller(FLC). To evaluate the performance of the proposed FLC design method, we make an experiment on the FLC for the speed control of an actual DC series motor system with nonlinear characteristics. Experimental results show that the proposed controller has better performance than PD controller.

In this paper, we study empirically examined the adventurous investments in corporate venture capital (CVC) firms' investment in the U.S. based corporate venture capital industry. Unlike existing studies focusing CVC firm's characteristics related to parent corporates and regarding CVC firm as a vehicle of corporate venturing, we identified CVC firm as an independent learning agent to adapt to dynamic environment and investigate their exploration and exploitation in investments based on organizational learning theory. Specifically, we investigate the market-environmental factors affecting CVC's adventurous investment in different sector rather than previously done. First, we examined competition intensity in CVC industry might be related to CVC firm's explorative investments. Second, CVC firm's investment experiences might affect as an inertia to invest on unexperienced sector. Finally, we investigated risk preference effect on CVC firm's venturing investments. The empirical data analyzed in the study contained a total of 85 U.S. based CVC firms and their 2,306 investments from 1996 until 2017. After conducting a GEE regression analysis and a Logit regression analysis, we found the significance and direction of our independent and moderating variables strongly supported all of our four hypotheses in a highly robust manner.

Due to the recent technological improvements, the environments of e-books and its contents have been changed and the users of e-books have drastically increased. This study aimed to propose a model on how children access and search e-books in this digital era. For this study, a potential model was proposed based on the analyses on various information-seeking behavior models. For analyzing children's access and search processes on e-books, 30 children in five public libraries or school media centers in Seoul and Kyoungi-do areas were recruited for the in-depth interviews. As a potential model on children's access and search on e-books was re-visited and revised based on the results, a cyclic model of children's access and search on e-books was proposed containing six factors.

ICT education guidelines revised in 2005 reinforce computer science elements such as algorithm, data structure, and programming covering all schools. And Ministry of Education emphasizes STEAM education. Most important is that "How instruct them". This means necessity of contents. So this paper suggests learning method of Stack and Queue using LEGO MINDSTORMS NXT. The main purpose is that how stack and queue are used, when robot explore realistic maze. Teaching and learning strategies are algorithm, flowchart, and NXT-G programming. Simple maze has path in left or right, but complex maze has three-way intersection. These are developed by authors. Master robot explores maze and push stack, and then return to entrance using stack. Master robot explores maze and transmits path to slave's queue. And then slave robot drives without exploration. Students can naturally learn principles and applications of them. Through these studies, it can improves ability of logical and creative thinking. Furthermore it can apply to ICT and STEAM education.

The purpose of this study was to investigate information source of the choice of select dental medical institution and the relationship between socioeconomic characteristics and information searching pattern. This study was conducted for residents adults and teens living in Gwangju and rural communities of Jellanam-do province including. The study shows that 61.0 % of the information of selecting dental medical institutes had been introduced by the acquaintance and the rest of the information(37.0%) had been gotten from the internet. The purpose of this study is to develop an information search method that can influence the choice of medical consumers in dental clinics, and to establish a new dental clinic management strategy based on this research. Plus, we want to develop an information search source that can have a convergence effect on the selection of medical consumers in dental medical institutions.
