최근 음성인식에 관한 연구가 활발히 진행되고 있지만, 음성으로 기기를 작동시키기거나 신원을 파악하는 등과 관련된 성인 음성 인식에 관한 연구들이 대부분이고 아기의 울음소리를 감지하기 위한 학술적인 연구는 미비한 실정이다. 아기들은 통상 울음으로서 자신의 상태를 표현한다는 점을 고려해 볼 때 기존의 성인을 대상으로 한 연구 결과를 그대로 적용시키기에는 무리가 따른다. 아기의 울음소리를 정확히 감지할 수 있다면 아기 및 유아를 위한 다양한 헬스(케어)기기에 적용될 수 있을 것이다. 따라서 대부분의 헬스(케어)기기들이 가지는 제한적인 자원과 컴퓨팅 능력을 고려하여 간단하면서도 정확도가 높은 방법이 필요하다. 이에 본 논문에서는 아기 울음소리의 진동수 패턴을 통계적으로 분석하여 아기 울음소리를 감지하는 방법을 제안한다. 다양한 주변 소리 샘플들을 통해 본 논문의 방법을 검증해본 결과 오감지율이 8.1%로 우수한 결과를 얻을 수 있었다.

Applying iterative learning utilizing SNS & Community to the class for pre-kindergarten teachers, the effectiveness of teaching satisfaction, self-efficacy, and curriculum understanding was verified. A iterative learning model utilizing SNS & Community in teachers leading traditional off-line teaching at college education field was applied separately into thinking to one-self by advance organizer, thinking together by presentation in the beginning of the class, and sharing the thoughts by community activities after the class. Iterative learning begins by being sent SNS to students from teachers before the class, but learners for themselves subsequently start to proceed self-directed learning activities. As a result, class satisfaction and understanding of pedagogy have been increased, and it had a positive influence on self-efficacy. Thus, it is to suggest utilizable SNS of professors and a teaching method utilizing Community to college students who need basic learning skills.

Objective: This study aims to analyze research trends related to software education for young children, focusing on studies published in Korea from 2016 to 2019 March. Methods: A total of 26 research publications on software education for young children, searched from Korea Citation Index and Research Information Sharing Service were identified for the analysis. The trend in these publications was classified and examined respectively by publication dates, types of publications, and the fields of study. To investigate a means of research, the analysis included key topics, types of research methods, and characteristics of the study variables. Results: The results of the analysis show that the number of publications on the topic of software education for young children has increased over the three years, of which most were published as a scholarly journal article. Among the 26 research studies analyzed, 16 (61.5%) are related to the field of early childhood education or child studies. Key topics and target subjects of the most research include the curriculum development of software education for young children or the effectiveness of software education on 4- and 5-year-old children. Most of the analyzed studies are experimental research designs or in the form of literature reviews. The most frequently studied research variable is young children's cognitive characteristics. For the studies that employ educational programs, the use of a physical computing environment is prevalent, and the most frequently used robot as a programming tool is "Albert". The duration of the program implementation varies, ranging from 5 weeks to 48 weeks. In the analyzed research studies, computational thinking is conceptualized as a problem-solving skill that can be improved by software education, and assessed by individual instruments measuring sub-factors of computational thinking. Conclusion/Implications: The present study reveals that, although the number of research publications in software education for young children has increased, the overall sufficiency of the accumulated research data and a variety of research methods are still lacking. An increased interest in software education for young children and more research activities in this area are needed to develop and implement developmentally appropriate software education programs in early childhood settings.

Six preservice teachers who participated in the "2016 service of summer vacation daycare programs by university and college students" focused on the programs for the formation of art, music and physical education and recreation culture were selected as research participants. The meaning of the experience they had through the service process was qualitatively analyzed. The subjects accepted the purpose of the self-directed service in which they should themselves solve a series of the entire process, from planning a volunteer program through drawing up the budget and purchasing materials to practice, evaluation and expressed the intention of participation. A volunteer program was conducted including visiting a daycare program for lower graders of elementary school (1st and 2nd grades) with more than 40 class hours during vacation. As research materials, research participants' journals, transcripts of individual interviews and group interviews, transcripts of phone calls, e-mail messages, and self-evaluation records of each class hour were collected. To increase the reliability and validity of the study, triangulation, member check, advice and review of the experts were conducted. In the study results, the volunteering experience-related significance for the preservice teachers who participated in the self-directed service were broadly categorized into 'Becoming a capable professional teacher', that consists of 'Increasing the power of thinking', 'Realizing the importance of communication', 'Doing together itself is important' and 'Ability to apply information and resources is needed'. 'Increase the continuity between preschool and elementary education' was subdivided into 'Get to know the necessity of the continuity between preschool and elementary education' and 'Want to learn the continuity between preschool and elementary education.'

The purpose of this study is to analyze the comtent of the education system of US and the UK in order to build an integrated system that can develop the leadership competency of preschool principle. Based on this, the implications are as follows. First, competencies can developed through learning rather than fixed. Therefore, re-conceptualization of leadership competence appropriate to the characteristics and organization of the individual as the presiding authority of the preschool can be considered as ability to show visible knowledge and skills, invisible self concept. Therefore, it is necessary to establish a capacity development plan based on this. Second, the introduction and implementation of continuous and systematic training programs such as the training system that strengthens the capacity of the directors and principals of the United States and the United Kingdom is necessary. To do this, we must introduce a system that renews certification every five years, like the United States, rather than a system that acquires and maintains certification with a single training. Third, various training methods should be carried out. In the case of the US and the UK, we think it is desirable to train in various ways in the training period, the university, the teacher center, and the private organization or association. Therefore, it is necessary to build a cooperation system with various institutions such as training institutes, universities, teacher centers, educational information research institutes, and private organizations in each province, and strengthen them in various ways. Fourth, the contents and methods of qualification training and future job training of the director of the preschool should be deviated from the uniform level. Therefore, the systematic research that reflects the knowledge and contents of the administration required in the field should be given priority by the university or research organization that is in charge of the training.

Software education is drawing attention as an education for fostering future talents who will lead the 4th industrial revolution. The purpose of software education for everyone from kinder to adults is not simply to develop programming skills, but to develop "Computational Thinking," a problem-solving ability that effectively solves real-world problems based on computing. Therefore, how to cultivate and evaluate computational thinking is a very important issue. This paper proposed a method of applying a process-based performance evaluation method to evaluate computational thinking ability in the process of solving learners' problems. The developed contents were revised and supplemented through two Delphi surveys by a group of experts consisting of five university professors and five incumbent information teachers majoring in computer science and computer education to verify the effectiveness of the final model. I hope This paper can contribute to the study of evaluating computer thinking ability from the perspective of problem solving.
