Objectives: The purpose of this study is to evaluate the program theory of a lifestyle intervention program for the prevention and treatment of metabolic syndrome. Methods: The program evaluated is a tailored intervention for multiple health behavior associated with metabolic syndrome which is informed by theoretical constructs from the Intervention Mapping and Transtheoretical model. The program components include one-to-one health counseling, a self-management handbook, and a health diary. To evaluate program impact theory we examined the logic of program goals and objectives, intervention methods and strategies, and the theoretical constructs of program materials through document review and matrix building. Results: This evaluation has found that the intervention program applied social cognitive theory constructs to design intervention methods and strategies in addition to the Transtheoretical model: self-monitoring for goal setting and monitoring skill, outcome expectation for the benefits of health behavior change, and interaction with environment for observational learning through modeling. While the intervention addresses multiple determinants and behaviors, it is limited to an individual level and lacks social and environmental approaches. Following the Transtheoretical framework, the contents of the intervention materials were developed utilizing consciousness raising as a main strategy for earlier stages of change, and counterconditioning and stimulus control for later stages of change. Conclusion: Program theory evaluation can be a process of enhancing program validity. It would also be necessary for providing basis for efficient program implementation. When comparisons of program theory between similar programs are possible, program theory and validity will be strengthened when comparisons of program theories between similar programs are possible.

Education policy is a dynamic process featuring social development trends. The world countries have focused their education program on empowering the learners for future life and work. This paper aims to assess the higher education curriculum based on a survey of 280 students, employers, alumni, and lecturers in both social sciences and natural sciences in Ho Chi Minh City, Vietnam. The fuzzy decision-making method, namely the Fuzzy Extent Analysis Method (F-EAM), was applied to measure the relative weight of each parameter. Seven factors under the curriculum development have been put in the ranking. Input with emphasis on foreign language was the highest priority in curriculum development, given the expected demand of the labor market. Objective and learning outcome and teaching activities ranked second and third, respectively. The traditional triangle of teaching content, methodology, and evaluation and assessment are still proven their roles, but certain modifications have been defined in the advanced curriculum. Teaching facilities had the least weight among the seven dimensions of curriculum development. The findings are helpful for education managers to efficiently allocate scarce resources to reform the curriculum to bridge the undergraduate quality gap between labor supply and demand, meeting the dynamic trends of social development.

21세기 지식기반 사회의 엔지니어들에게는 전공분야의 전문성뿐만 아니라 창의적 사고, 읽기/쓰기 능력, 의사소통 능력, 사회 경영 경제에 대한 이해 능력, 윤리의식과 같은 인문사회학적인 전문교양 지식이 요구되고 있다. 전문교양 지식은 꾸준히 그 분야에 관심을 갖고 관련된 글을 읽으며 자신의 생각을 정리하여 표현해 보는 것이 무엇보다 중요하지만, 한정된 정규교육과정 내에서 보다 높은 수준의 학습 성과 달성이 어려운 것이 현실이다. 이 연구에서는 공과대학 학생들의 전문교양 지식 함양을 위한 스마트폰 앱을 개발하고 수업에 적용함으로써 언제 어디서나 교수자가 구조화한 지식을 학습자와 실시간 상호작용하고 학습자 스스로 지식을 재구성할 수 있는 환경을 제공하여 일상생활 속에서 전문교양 지식의 수준을 향상시킬 수 있는 방안을 제안하였다.

PURPOSE: Previous studies have shown that healthy young adults reduced gait velocity during texting or talking while walking. It was reported that increasing number of pedestrian accidents were related to distract the environmental attention. The purpose of this study was to compare the effects of texting and texting while listening to music on gait parameters. METHODS: Texting and listening to music while walking were assessed in two dual-task condition using 35 healthy young adults. The outcome measurements were assessed in terms of spatiotemporal gait parameters in three walking conditions, namely, comfortable walking speed, walking while texting, and walking while texting and listening to music. To avoid learning effect, subjects were individually blinded to assessment schedule and space. The changes between the three walking conditions were analyzed using repeated measures ANOVA. RESULTS: When comparing the two dual-task conditions with the single-task condition, it was found that dual-task interference was increased in almost gait velocity, cadence, stride length, step time, double limb support, and single limb support. In addition, walking while texting and listening to music condition negatively was affected gait speed, stride length, and step time more than the texting only condition. CONCLUSION: Walking while texting and listening to music as well as waling while texting may decrease pedestrian safety when crossing streets by diverting the person's attention away from the street environment.

This paper focuses on how the latest progress in digital media and technology affects the writing education environment. In the contemporary era, collecting numerous pices of information online, and arranging them to create new knowledge is important. There is also a need to seek new methods for writing education to stay in tune with the times. To that end, this paper suggests an open writing model using hypertexts. This writing model consists of a total of five stages, which are use of information, compilation of information, open mutual discussion, search of additional information and writing to recreate knowledge. The final outcome of such writing is writing using footnotes. By describing the gist of the keyword and adding numerous footnotes, such writing opens up an infinite possibility of re-creating information into new knowledge. This method can help university students who are accustomed to the digital society to proactively use information and improve multi-disciplinary communication skills required today. This author applied such a model to university writing education and found that more than 82% of the students were satisfied. Through the process of collaboration and recreation of knowledge in writing, learners found distinct benefits and noted their horizons had broadened. Given this effect, the open writing model using hypertexts is meaningful in that it forms a learning community that goes beyond a one-way feedback from instructor to student and instead nudges students to realize collective intellect. Moreover, it is meaningful in that it moves away from a top-down approach of the instructors passing down knowledge about writing and its rules, and towards a more proactive involvement by students in creating knowledge.

본 연구에서는 공대의 교과과정에서 흔히 요구되는 팀 활동에 대해 신입생들을 대상으로 팀 활동의 만족감과 관련 요인들을 분석하였다. 입문교과를 수강하는 신입생 64명을 대상으로 13개의 팀을 구성하여 총 5개의 개방형 과제를 통해 팀 활동을 수행하게 한 후 설문조사를 실시하였다. 팀 활동에 대한 전반적인 만족감은 팀의 성과에 긍정적인 영향을 미침을 확인할 수 있었다. 그러나 팀 만족도는 팀의 성과보다는 팀원의 활동 참여도와 팀원 간의 관계가 좋다고 인식하는 정도에 더욱 상관관계가 있음을 발견하였다. 학생들은 상호 배려하는 화목한 팀 분위기가 조성될 때 팀 활동의 만족감이 증가하며, 팀의 분위기가 성과보다 중요하다고 느끼고 있었다. 한편 팀원의 역할별 구성은 팀 활동의 만족도와 직접적인 관계가 없었으며, 또한 자율적인 팀 구성에 대한 선호도가 높음을 알 수 있었다. 이러한 결과를 바탕으로 학생들의 팀 활동 만족감이 극대화되도록 지원을 한다면 특히 최근 학제적 융복합 학습 환경에서의 팀 활동을 통한 교육적인 효과가 높아질 것으로 기대한다.

All the imputation techniques proposed so far in literature for data imputation are offline techniques as they require a number of iterations to learn the characteristics of data during training and they also consume a lot of computational time. Hence, these techniques are not suitable for applications that require the imputation to be performed on demand and near real-time. The paper proposes a computational intelligence based architecture for online data imputation and extended versions of an existing offline data imputation method as well. The proposed online imputation technique has 2 stages. In stage 1, Evolving Clustering Method (ECM) is used to replace the missing values with cluster centers, as part of the local learning strategy. Stage 2 refines the resultant approximate values using a General Regression Neural Network (GRNN) as part of the global approximation strategy. We also propose extended versions of an existing offline imputation technique. The offline imputation techniques employ K-Means or K-Medoids and Multi Layer Perceptron (MLP)or GRNN in Stage-1and Stage-2respectively. Several experiments were conducted on 8benchmark datasets and 4 bank related datasets to assess the effectiveness of the proposed online and offline imputation techniques. In terms of Mean Absolute Percentage Error (MAPE), the results indicate that the difference between the proposed best offline imputation method viz., K-Medoids+GRNN and the proposed online imputation method viz., ECM+GRNN is statistically insignificant at a 1% level of significance. Consequently, the proposed online technique, being less expensive and faster, can be employed for imputation instead of the existing and proposed offline imputation techniques. This is the significant outcome of the study. Furthermore, GRNN in stage-2 uniformly reduced MAPE values in both offline and online imputation methods on all datasets.

여러 대의 카메라를 이용한 감시 시스템이 정확하고 효율적으로 동작하기 위하여 카메라 시야 간의 연결 관계를 아는 것이 필수적이다. 카메라들의 연결 관계를 파악하기 위하여 카메라 시야 내의 출입 영역을 검출하는 일이 선행되어야 한다. 본 논문에서는 카메라 시야에서 객체의 등장 및 퇴장으로부터 얻은 데이터에 그래프 이론 기반의 클러스터링(clustering)을 적용하여 시야 내의 출입 영역을 검출하는 방법을 제안한다. 데이터 포인트들 사이의 관계를 조사하여 최소신장트리를 구성하고, 트리의 에지들 중 일관성을 갖지 않는 것들을 삭제하여 well-formed 클러스터를 얻는다. 본 논문에서는 클러스터의 형태를 설명하는 두 가지 특징을 정의하고 이를 클러스터의 분할 조건으로 사용하였다. 실험결과를 통하여 데이터 포인트의 분포가 조밀하지 않은 경우 expectation maximization(EM)에 기반을 둔 방법에 비하여 치안하는 방법이 보다 효과적으로 클러스터링을 수행함을 확인하였다. 또한 EM 기반 방법들에 비하여 안정적인 결과를 얻기 위해 필요한 데이터 포인트의 개수가 적으므로 출입영역에 대한 학습시간을 단축할 수 있다.

Objectives: This study aimed to develop dietary education textbooks for elementary school students by focusing on the three core values of environment, health and gratitude from the National Food Education Plan. Methods: The contents of textbooks and teacher's guidebooks were developed with brainstorming of the authors as well as consultation with experts and by considering not only the three core values of environment, health, and gratitude, but also the performance indicators of the 2nd National Food Education Plan and the key competencies and creative convergence approach of the 2015 revised national curriculum. Results: A total of 12 different dietary education textbooks named 'Good Dietary Life Guide' and the teachers' guidebooks from the first to the sixth grade of elementary school were developed. The textbooks were fundamentally developed connecting the three core values, the outcome indices of the 2nd National Food Education Plan and the key competences of the 2015 revised national curriculum. Various educational activities such as thinking, debate, writing, cooperative learning, experience, practice were included to promote students' participation. These books could be utilized in every field of dietary education targeting elementary students such as creative experiential activity, convergent classes (integrated subjects, Practical arts, Social studies, Science, Moral education and Korean), after school classes, rural experience, general agricultural education, after-school child care services and community child care centers. Conclusions: The continuous and repetitive use of the textbooks from the first to the sixth grade would contribute to the improvement of food habits and the personalities of elementary school students, and consequently make the students grow up as healthy citizens.
