최근 새로운 산업 환경의 변화에 필요한 맞춤형 기업 인재양성을 위한 효과적인 교수학습방법으로 플립러닝이 주목 받고 있다. 기존 강의식 수업방식의 경우 중도탈락률이 높고 창의적 문제 해결력을 저해하는 등의 다양한 문제점이 있다. IT 공과대학의 경우 선수 교과목의 선행이 필요한 전공 이론과목이 대부분이므로 학생들의 학습 참여도와 학업 성취도를 높일 수 있는 효과적인 교수학습방법의 개발이 필요하다. 본 논문에서는 학생들의 학습 동기를 유발하고 자기 주도적 학습을 통한 학습 효과를 높이기 위해 플립러닝과 실습수업을 병행한 5단계 플립러닝 수업모형을 제안하였다. 또한 컴퓨터공학과의 알고리즘 수업에 적용하여 학습 효과를 분석하고 그 결과를 바탕으로 문제점 및 활용방안을 제시하고자 한다.

본 연구는 인구주택총조사 자료(1985~2010년)를 이용하여 여성의 경제활동참여가 출산율에 미치는 영향을 실증분석하였다. 분석결과 1985년을 제외한 1990, 2000, 2005, 2010년에 여성의 경제활동참여는 여성의 총 출생아 수를 통계적으로 유의하게 낮추는 효과가 발생함을 확인할 수 있었다. (-) 효과의 크기는 1990년부터 점차 커져 2005년에 가장 크게 나타났으며 2010년에는 2005년 대비 그 크기가 상당히 감소한 것으로 나타났다. 이러한 감소의 효과는 일부 정부의 일과 가정 양립을 위한 정책에 따른 효과로 볼 수 있을 것이다. 따라서 정부의 일과 가정의 양립을 위한 지원 정책의 확대와 정책 사각지대에 대한 보완이 필요하며 이와 더불어 현재 추진 중인 정책에 대한 수혜율(take-up rate)을 높일 수 있도록 정책을 추진하는 것이 중요할 것이다.

광자(Photon)이나 전자기파(Electromagnetic Wave) 등의 형태로 직접 열을 전달하는 특징을 가지고 있는 복사열전달은 중간 매질의 열전달 관여여부에 따라 표면복사(Surface Radiation)와 기체복사(Gas Radiation)의 형태로 구분될 수 있다. 본 연구에서는 원통 형상에서의 표면복사에 대해 미지의 복사물성치들을 역해석 방법을 이용해 역추정하였다. 이때, 효율적인 역해석을 위해 반발 입자 군집 최적화(Repulsive Particle Swarm Optimization, RPSO) 알고리즘을 역해석 기법으로 채택하였다. 이로부터 얻은 해의 수렴성과 정확도 등을 기존의 유전알고리즘(GA) 결과와 비교해 봄으로써, 표면복사 현상에 대한 역해석의 적용 가능성을 고찰하고자 하였다.

The purpose of this study was to determine whether gender differences existed in knee valgus kinematics in college students when performing a vertical drop landing. The hypothesis of this study was that females would demonstrate greater knee valgus motion. These differences in knee valgus motion may be indicative of decreased dynamic knee joint control in females. This study compared the initial knee valgus angle and maximum knee valgus angle at the instant of impact on vertical drop landings between healthy men and women. In this study, 60 participants (30 males, 30 females) dropped from a height of 43 cm. A digital camera and two-dimensional video motion analysis software were used to analyze the kinematic data. There was significant difference in the mean knee valgus angle at initial contact landing between the two groups (Mean=$7.88^{\circ}$, SD=$4.24^{\circ}$ in males, Mean=$12.93^{\circ}$, SD=$2.89^{\circ}$ in females). The range of knee valgus angle on landing (Mean=$3.25^{\circ}$, SD=$5.72^{\circ}$ in males, Mean=$11.44^{\circ}$, SD=$6.39^{\circ}$ in females) was differed significantly (p<.05). The maximal angle of knee valgus on landing (Mean=$10.91^{\circ}$, SD=$6.89^{\circ}$ in males, Mean=$24.25^{\circ}$, SD=$6.38^{\circ}$ in females) was also differed significantly (p<.05). The females landed with a larger range of knee valgus motion than the males and this might have increased the likelihood of a knee injury. The absence of dynamic knee joint stability may be responsible for increased rates of knee injury in females. No method for accurate and practical screening and identification of athletes at increased risk of ACL injury is currently available to target those individuals that would benefit from neuromuscular training before sports participation.

Objectives: The current survey environment is changing and participation rates in national nutrition surveys are decreasing. Therefore, the purpose of this study was to develop strategies for improving the nutrition survey system in the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: To develop an alternative system for conducting the KNHANES nutritional survey, we conducted focus group interviews with stakeholders of the survey, SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis, and expert reviews. In addition, spatial analysis of potential sites for conducting surveys instead of relying on household visits was performed, and the perception of nutritional surveys in the population eligible for KNHANES was evaluated. Results: Based on the results of the focus group interviews, SWOT analysis, and expert reviews, we propose two options for survey sites: vehicles specifically prepared for nutritional surveys and public facilities such as community service centers or public health centers. Among public facilities, community service centers were found to be more appropriate sites than public health centers because they were considered more accessible. About 90% of respondents would participate in the survey in public facilities and about 74% would in vehicles. Conclusions: Conducting national nutrition surveys in specially designed vehicles and public facilities could be a viable alternative to home visits. Next, the validity of these newly proposed nutrition survey methods needs to be compared to the results of the current national nutrition survey.

본 연구는 이공계 전공자들의 노동시장 성과, 특히 사회적 위신이 타 전공자들에 비해 낮다는 논의에 대한 경험적 검증이다. 대학졸업자의 전공계열에 따라 고용 확률, 고위직, '좋은 직업' 획득 확률에 차이가 있는지를 2000년 인구주택총조사의 2% 표본을 이용하여 분석하였다. 표본 선택편향을 수정한 2단계 프로빗 모형 분석 결과, 이학계와 공학계열 전공자가 인문사회계열 전공자에 비해 고용, 고위직, '좋은 직업' 획득 확률이 유의하게 낮다는 증거는 발견되지 않았다. 하지만 공학계 전공자의 경우 노동생애 초기에는 인문사회계 전공자에 비해 유의하게 높은 '좋은 직업' 획득 확률을 가지지만 연령 증가와 더불어 이러한 이점이 빠르게 사라져 40대 이후로는 인문사회계보다 '좋은 직업' 획득 확률이 낮다. 이는 공학계에서는 현장 경험에 의한 인적 자본의 축적률이 낮고, 대학에서 습득한 기술이 급격히 노화되기 때문일 가능성을 시사한다.

Objectives : To explore the information sources and knowledge on infant vaccinations of pro-vaccination community members and anti-vaccination community members on the internet. Methods : An online survey of 245 parents from three pro-vaccination communities and 92 parents from one anti-vaccination community was conducted from June 7 to June 23, 2006. Results : Parents from pro-vaccination communities usually gained the information regarding vaccination efficacy and risk mainly from healthcare providers (49.8%) and mass media (47.7%). Pro-vaccination community members considered healthcare providers as the most credible sources of information on vaccination, whereas the anti-vaccination community members usually gained their information regarding vaccine efficiency and risk from Internet child-care cafes and online vaccination communities. Parents of the anti-vaccination community considered the internet as the most credible information source (77.6% for efficacy, 94.8% for risk). In addition, the major reason why anti-vaccination community members didn't vaccinate and, will not vaccinate, was concern about possible side effects of the vaccine. The knowledge level on infant vaccination, education and economic status was higher in the anti-vaccination community. Conclusions : On-line communities concerned with vaccination are getting popular. The influence of anti-vaccination parents on the Internet is expected to be high. The government and healthcare providers need to increase their efforts to improve the credibility of information about vaccination. Our findings suggest that online communication regarding vaccinations needs to be considered as a means to increase vaccination rates.

The aim of this study was to identify the most effective methods with which to revitalize Korean high school culinary education. To achieve this aim, a culinary recognition questionnaire survey of 616 students from 9 culinary high schools was carried out. The 9 surveyed schools represented the following of 7 regions: Chungnam, Busan, Incheon, Daegue, Jeonbuk, Gyeongbuk, and Gwangju. Collected data were subjected to descriptive analysis, $x^2$-test, t-test, and one-way ANOVA using SPSS(version 14.0). The results of this study are as follows. Culinary practice interest and learning demand of most students were high. 6.8% of students indicated that initial theory learning, followed by video education, and finally live demonstration is an effective teaching methodology. They preferred practicing on actual ingredients as the primary teaching and learning method, nominating technician cooking as the most favorite. As for areas needing improvement in culinary practice education, difficulties with material preparation and insufficient learning hours were identified as prominent factors by 66.8% of respondents. There was unanimous agreement that culinary practice education can be enhanced by highly skilled teachers, while interest for the discipline itself can be fostered by initiating and encouraging cooking participation in the home. Freshmen and special high school students suggested that a cooking related website is necessary to expand the current information interface, which is currently limited to colleagues and employers. In relation to culinary education revitalization, consistent promotion of departments, or high schools that have proven student satisfaction rates and effective culinary curriculum are required. Furthermore, teachers can also aid this process by more effective student pastoral care in order to improve school life satisfaction. However, teacher job satisfaction is an important component of this process, and better employment conditions and remuneration packages reflecting extra work must be considered as part of an attractive teacher-incentive employment policy.

Since 1982, the government of Korea has actively promoted vertical cooperative R&D programs between government-sponsored research institutes (GRIs) and private firms. A number of firms participated in the programs because cooperative R&D could lower the risk and could contribute to rapid commercialization of many technologies. This paper examines the effectiveness of vertical cooperative R&D projects by the modes of cooperation between GRIs and industrial firms, and analyzes the performance of participating firms' technology sourcing strategies for commercial utilization of cooperative R&D results at the project performed from 1982 to 1989 under the Government-Industry Cooperative R&D Program sponsored by the Ministry of Science and Technology(MOST) in Korea. The cooperative R&D projects are classified into 4 groups by two criteria, i.e., the level of participation of firms, and the breadth of cooperation. The findings suggest that firms should actively participate in cooperative R&D projects. In addition, in order to enhance commercial success, cooperation between GRIs and industrial firms should not be limited to R&D stage only. The breadth of cooperation should be extended to commercialization stage. Small- and medium-sized firms participating in vertical cooperative R&D projects in Korea usually lack internal technological capabilities that are needed to commercialize the results of cooperative R&D. Three different technology sourcing strategies - exclusive cooperative R&D strategy, in-house development augmented cooperative R&D strategy, and licensing-in supplemented cooperative R&D strategy - are empirically derived through cluster analysis of the relative usage rates cooperative R&D and of other supplementary technology acquisition methods. The findings suggest that the firms participating in vertical cooperative R&D projects should try to utilize other supplementary technology acquisition methods in order to achieve commercial utilization of the vertical cooperative R&D results.
