화재 등 재난으로부터의 어린이 안전관리를 기존의 담당기관과 관계자들에게만 맡겨놓고 있을 수는 없다. 국민 각자가 일상 속에서 안전에 대한 의식과 지식, 그리고 정보를 습득하고 유사시에 대응할 수 있도록 안전관리를 체질화하고 생활화해야 한다. 이를 위해 민과 관이 함께 해야 할 활동이 교육 홍보의 차원에서 무엇이 있는지 구체적이고 면밀히 조사연구 하길 바라며 그에 따른 후속 프로그램의 개발 또한 중요하다. 안전문화의 형성을 위한 제대로 된 교육시스템 마련이 중요하다. 관련 교과과정에 안전교육을 의무화하고 집체교육이 가능한 장소에서의 소방.재난 관련 체험 위주의 프로그램을 마련해야 한다. 특히 안전 불감증의 문제는 우리나라만의 문제가 아니다. 다만 '지속성' 과 '계속성' 에 차이가 있을 뿐이다. 우리나라도 '전 생애적 안전관련 프로그램' 을 마련하여 어릴 때부터 조기에 체험할 수 있도록 프로그램을 구성해야 할 것이다. 이와 관련한 관점에서 어린이 안전관련 부처별 업무현황과 추진상황 등을 분석하고 미국 등 선진외국의 어린이 안전사고 방지를 위한 안전교육제도 및 시스템 등의 소개를 통하여 앞으로 민.관 차원에서 현실적인 문제점을 개선할 수 있는 방안을 제시하고자 한다.

개방형 액체로켓엔진 시스템에 대한 동특성 예측 프로그램을 작성하였다. 이 프로그램을 통해 얻은 펌프 시동 시 시간에 따른 압력 및 유량 변화 결과를 수류실험장치를 구축하여 실험적으로 검증하였다. 수류실험장치는 실제 액체로켓엔진 추진제 공급 계통에서 구성품의 형태와 배치위치, 가스발생기와 주연소실로 분기되는 유량비를 기준으로 모사되었다. 측정 시 관로가 채워진 상태에서 펌프를 시동하였으며 펌프는 전동기로 구동된다. 동특성 예측 프로그램의 작성을 위해 구성품별 동특성 모델링을 수행하고 엔진 시스템을 기준으로 각 모델링을 순차적으로 통합하였다. 구성품의 동특성 파라미터를 측정 반영하였고 압력 밸런싱을 통해 수렴 조건이 결정된다. 수렴된 밀도와 유량을 가지고 다음 시간에서의 초기 입력 값으로 대체하여 계산을 수행하였다. 천이 작동 상태에서 엔진 시스템 내의 물리량 변화를 전산 예측과 더불어 실험적으로 측정하고 비교하였다.

The purpose of this paper was to understand the outlines of 1) common and free curricula implemented by the first pilot schools and 2) Home Economics related programs from both curricula. This study analyzed the 42 reports from the first pilot schools which implemented the free learning semester in 2013. The results showed that more than half of schools set two or more emphasis models of the free learning semester. In 15 out of 28 schools, the lesson hours of Home Economics were reduced by one to three hours. Various common curricula were implemented in many aspects of teaching-learning methods, curriculum, evaluation, and subject related career lessons. Free curriculum was implemented in four areas such as career exploration, student optional program, club activity, and art sports activity. In common curriculum, Home Economics was carried out in 17 out of 39 schools. The Home Economics class included subject related career lessons and improvement of teaching- learning methods. Various interesting activities and programs as a free curriculum were implemented in career exploration, students' optional program, and club activities in 38 schools. The most frequently implemented was the activity program related to food and nutrition. Further research was proposed to develop students' optional programs related to Home Economics subject, responding to their needs.

This study aims to investigate the current status of the operation system of the curriculum support extra-curricular program, focusing on the extra-curricular program operation system of other universities, and suggest the desirable operation system and performance management plan of the extra-curricular program in cultural education. To this end, the analysis of the extra-curricular program operation system of eight four-year universities in the Seoul metropolitan area was conducted on the existence of core competencies, computer systems and extra curricula program guides, credit-linked and mileage scholarship programs, and the analysis focused on the characteristics, merits and demerits of each university's operating system. It was also intended to propose the desirable operation system and performance management plan of the extra curricula program in liberal arts education, focusing on the operation system of the extra curricula program of E University and the corresponding performance management. Conclusion To operate the extra curricula program efficiently, the computer system and the extra curricula program guide, credit link and mileage scholarship system should be introduced. In addition, the analysis of the operation system of the curriculum support program of E University shows that E University operates systematically with the direction of operation of the core competency-based curriculum support extra-curricular program, and the performance management of the extra curricula program of E University is carried out through the EU-TQM System Integrated Management System.

This study used Q methodology for analogizing culinary arts major students' subjectivity through their participation of one of restaurant start-up experience program, called pop-up restaurant. The study tried to figure out particular structure of among students' responses and noticed five distinctive types. There were Increase learning effect type(Type 1, N=4), Collaboration of members importance type(Type2, N=8), Marketing PR need type(Type3, N=6), Restaurant business plan type(Type4, N=4), Industry work experience required type(Type5, N=3). The study also revealed that each type contained diverse characteristics figures in their own. The research finding could be used as fundamental source of future similar research but in other research methodology in the format of difference among students or diverse measuring point of time frame.

The purpose of this study is to investigate engineering students' attitude toward convergence and relevance with engineering education accreditation, gender, and academic year and attitude toward convergence. To be specific, fist, we examined whether the instrument for measuring attitudes toward convergence were reliable and valid for engineering students. Second, we compared levels of attitudes toward convergence in terms of engineering education accreditation, gender and academic year. Third, latent classes, which were distinguished in terms of attitudes toward convergence, were identified. Participants were 2076 engineering students. By using factor analysis and Rasch analysis, validity and reliability of instrument measuring attitudes toward convergence were confirmed. The differences in attitude toward convergence in terms of engineering education accreditation experience, gender, and academic year were examined by independent t-test and ANOVA. There were significant differences in attitude towards convergence in terms of engineering education accreditation, gender, and academic year. Students who experience engineering education accreditation program and male and high academic year have higher levels of attitude toward convergence than others. Lastly latent class analysis (LCA) was conducted to identify subgroups underlying engineering students in terms of attitude toward convergence and five latent classes were identified. In addition, the chi-square results showed that there were significant relationships between identified latent classes and engineering education accreditation, gender, and academic year. Based on these results, engineering education considering students' characteristics and diversity in attitude toward convergence were discussed.

Pan-So-Ri singing a story as song is one of Korea traditional musics. it divide into two sect(east-sect, west-sect), and it is hard to classify two sect without knowledge about Pan-So-Ri. In this paper, we have propose a Pan-So-Ri classification program using PCD(Pitch Class Distribution) and Naive Bayesian Classifier. Attribute value of classifier is each appearance frequency of pitch. Experiment is conducted two time with different rounding off location of probability value. Better one show correct classification with east-sect 80%, west-sect 97%, and total accuracy of 88%. this result is used our program.

The aim of the study was to explore the effects of parental media mediation types on adolescents' perception of the usefulness of the broadcasting rating system. A total of 520 middle school students participated in the survey. Results showed a higher utility of 'autonomy-supportive restriction' strategy by the parents led to more positive perception of the usefulness of the rating system. This study argues that parents need to pursue a mediation strategy in which a rationale for prohibiting media contents use should be provided and in which the perspective of the adolescent is taken seriously.
