본 논문은 STEAM 교육의 이론적 배경과 국내 외 연구 사례를 살펴보고, 주제중심 프로젝트 기반의 STEAM 교육 프로그램을 개발하였다. 이 프로그램을 초등학교 6학년 과학 3단원 [에너지와 도구]와 4단원 [연소와 소화]를 중심으로 관련 주제들을 추출하여 적용해 보았다. 그 결과 이 프로그램에 따라 활동한 학생들의 과학 흥미도와 과학에 대한 긍정적 태도가 비교반과 비교하여 유의미한 차이를 보이며 증가하였다. 연구결과 주제중심 프로젝트 기반 STEAM 교육 프로그램이 과학 교육에 대한 인식, 흥미, 과학적 태도에 긍정적인 변화를 가져온다는 것을 확인하였다.

본 논문은 쿼드로터 무인기의 비선형 적응 자세 제어기 설계에 대한 것이다. 쿼드로터 무인기는 4 개의 추력기를 갖는 불완전한 비선형시스템으로써 모델 파라미터가 변화하기 때문에 특별한 제어기가 필요하다. 본 연구에서는 산업 응용에 따른 페이로드의 변화에 따라서 무인기의 모델파라미터가 변화하더라도 페이로드에 따른 튜닝을 자동으로 할 수 있도록 적응제어기를 설계하였다. 특히, 무인기의 수학적 모델을 이용하여 비선형 적응제어기를 설계하였고 리야프노프 함수를 이용하여 이론적으로 안정성을 분석하였고 페이로드 변화에 따른 시뮬레이션을 통해서 제어기의 성능과 파라미터 추정법칙의 유효성을 입증하였다.

This study was intended to investigate effects of building school forests on elementary school students, including changes in mental image of school, attitude toward nature and forest, and awareness of their relationship with school forest. The total number of 770 drawings and 1,124 writings were collected to be analyzed from three elementary schools. The results showed that there were significant differences between two student groups, respectively forest school group versus non-forest school group, in their mental image of school. For instance, more often observed in the drawings of forest school group students than their counterparts were natural and human elements, activities associated with nature, and natural or human elements located at central area. Also, more frequently found in the writings of forest school group students than their counterparts were letter-style sentences, stories about school forests, inherent values on nature and forest, and curiosity regarding the nature. These results seem to indicate that in order to materialize educational value of school forests, practical workshops for teachers need to be held as soon as possible and new activity models for students should be developed. In addition to that, long-term research on effectiveness of school forest have to be conducted to a number of schools.

Purpose： This study examined the effects of cognitive-behavioral therapy on problem-solving ability and dysfunctional attitudes in undergraduate students. Method： This study was conducted between September 2004 and May 2005. The subjects consisted of 23 undergraduate students. The experimental group (n=13) participated in a cognitive-behavioral therapy that consist of 8 session over an 8-week period. The control group (n=10) participated in a reality therapy that also consisted of 8 sessions over an 8-week period. Problem-solving ability and dysfunctional attitudes were measured for all subjects before and after therapy. These data were analyzed by unpaired t-test and t-test with the SAS program. Results： Following cognitive-behavioral therapy, the experimental group experienced a significant decrease in score of problem-solving ability and in approach-avoidance style (the subscale in the problem-solving ability). There were no changes in these values after the reality therapy in control group. Conclusions： In light of these results, cognitive-behavioral therapy has a positive effect on problem-solving ability in undergraduate students.

The concept of "new consumer sovereignty" is playing a significant role in having the initiative of production and consumption of technology and culture trend. Today the 'new consumers' positively use digital and information technology in purchasing. To understand these consumers' new purchase tendency, the study examined the actual conditions 1) of consumers' use of digital and information technology, 2) of digital devide between consumers, and 3) the consumer's attitude to changes of their lifestyle which digital convergence could result in. The subjects were thousand male and female adults. The data were collected from a survey conducted by Embrain, a research firm in Seoul, in the period of June 1st, 2007 ${\sim}$ June 10th, 2007. The results show: 1. Most subjects have computers, their Internet use is their general life, and they have lots of exposure opportunities to digital information. They positively and actively use information technology. 2. Between male and female subjects, and between old and young generation there is a significant digital gap. But the gap between regional areas is statistically not significant. 3. The subject's attitude to digital convergence society shows both positive expectation and negative concerns. Concludingly, to embody a desirable digital convergence society, it is necessary to be searched the ways which can decrease the digital gap and policy to share benefit that information technology can give to consumers.

본 연구에서는 최근 사회적 학문적 관심사로 떠오른 댓글의 읽기 효과를 살펴보고자 하였다. 이를 위해, 피험자로 하여금 기사와 댓글을 읽게 하여 기사주제에 대한 태도가 댓글에 의해 변화하는가, 또한 이러한 태도 변화에 영향을 주는 요인들은 무엇인가 실험을 통해 알아보았다. 연구결과 기사에 첨부된 댓글을 읽는 것만으로도 피험자가 기사주제에 대한 태도변화를 일으키는 것을 발견하였다. 또한 댓글을 읽은 후 태도가 긍정적 혹은 부정적으로 변화하도록 하는 별도의 요인들이 존재함을 발견하였다. 즉 댓글에 대한 신뢰도와 주제에 대한 효능감이 높을수록 댓글을 읽은 후 태도가 부정적으로 변하였으며 정보추구 성향과 댓글 이용동기가 높을수록 사후 태도가 긍정적으로 변함이 발견되었다.

The purpose of this study was to examine the effects of animation-based instruction on elementary students' level of understanding and interest on a plant's structure and function, using "Magic School Bus(Joanna Cole, Bruce Degen, 1986)". The understanding and interest measurements were administered to 99 fifth grade students at a elementary school located in Seoul. The study examined the changes in understanding and interest through pre-test and post-test of the two groups. Intensive interviews were conducted to find factors that enhance understanding and interest. Three key findings were revealed from the results. First, the animation-based instruction enhanced the level of understanding in the experimental group compared to the control group. Second, animation-based instruction made high-achieving students enhance their interest in topic component and attitude component. And, animation-based instruction did not led low-achieving students to increase their interest in the topic component and attitude component. We suggest that animation-based instruction positively influences students' understanding, but its effects on students' interest are dependent on their conceptual understanding of the topic.

Purpose: This study was to explore the effects of breast cancer education for college students on their mother's breast cancer screening promotion. Methods: This study used a one-group pretest and posttest design. Data were collected from September to November, 2007 from a sample of 80 college students and their mothers using a survey questionnaire, which asked about demographic variables, concerns over health and breast cancer, communication, stage of change and attitude (pros and cons) related to breast cancer, and confidence in breast self-examination. The college students received education about breast cancer for 50 minutes and then they educated their mothers about breast cancer. Data were analyzed with descriptive statistics and paired t-test. Results: The mean age of the college students was 22.0 years, and that of their mothers 49.4 years with a range from 43 to 58 years. After receiving education on breast cancer, there were significant changes in the mean scores of concerns about health and breast cancer, communication, pros in mammography, and confidence in practicing breast self-examination. Conclusion: This study indicates that education on breast cancer to mothers through their college-age daughters is effective and can be utilized to promote breast cancer screening for women.

This study attempted to measure self-disclosure changes of nurses a result of human relations training. The study population consisted of 49 nurses in Seoul. The instrument used in this study was the Self-disclosure questionnaire developed by Jourard in 1958, was designed to measure verbalized aspects of self-disclosure defined as a voluntary act of revealing personal data about oneself including beliefs, values, feelings and perceptions to another person. The SDG instrument is devided into six areas: attitude, taste and interest, personality, money, work and body. The main findings were summarized as follows: 1. After training, the subjects disclosed more than before. 2. Subjects tended to very the amount of self-disclosure with respect to the category of information to which an item about the self belonged. Two clusters of aspects emerged, a high disclosure cluster including Attitude, Tastes and Interests, Personality and Work, and a low disclosure cluster comprised of Money and Body. 3.
