  • This research will describe algorithm for class diagram extraction from problem statements. Class diagram notation consist of class name, attributes, and operations. Class diagram can be extracted from the problem statement automatically by using Natural Language Processing (NLP). The extraction results heavily depends on the algorithm and preprocessing stage. The algorithm obtained from various sources with additional rules that are obtained in the implementation phase. The evaluation features using five problem statement with different domains. The application will capture the problem statement and draw the class diagram automatically by using Windows Presentation Foundation(WPF). The classification accuracy of 100% was achieved. The final algorithm achieved 92 % of average precision score.

  • Objectives : The special class has been made, bringing rapid increase quantitatively. The authors carried out the child psychiatric interview and evaluation for 9 special-classed children in Asan city to find out clinical diagnosis and emotional/behavioral characteristics. Methods : The child psychiatrists evaluated special class children by DSM-IV and K-SADS-PL. Tools for the evaluation were Child Behavior Checklist- Korean version, Korean Personality Inventory for Children, Children's Depression Inventory, Abbreviated Conners Parent-Teacher Rating Scale-Revised, State-Trait Anxiety Inventory for Children, Vineland Social Maturity Scale, Wechsler Intelligence Scale for Children-III, and Childhood Autism Rating Scale. Results : Ultimately 53 children, consisting of 35 boys(67.9%) and 18 girls(32.1%), participated, and the average age was $10.5{\pm}1.3$ years old. Their measure of Vineland Social Maturity Scale was $78.7{\pm}20.0$, Childhood Autism Rating Scales was $25.4{\pm}9.0$, Child Depression Inventory was $22.2{\pm}5.2$, State-Trait Anxiety Inventory for Children was $35.2{\pm}8.2/36.5{\pm}6.2$, and Abbreviated Conners Parent-Teacher Rating Scale was $11.0{\pm}4.6$. In the clinical diagnosis evaluation, the prevalence rate of learning disorder was decreased compared to early research, ADHD had been newly appeared and depression disorder and anxiety disorder had been increased. Conclusion : This result suggests that a lot of children in a special class have complex emotional and behavioral problems in addition to educational problems.

  • 본 연구는 수업의 질 관리 및 개선을 위해 A대학에서 실행되고 있는 교과목 CQI양식에 대해 살펴보았다. A대학에서는 역량기반 교육과정으로의 개편아래에 수업의 계획, 과정, 결과가 체계적으로 관리 될 수 있도록 CQI양식을 개선하였다. 본 연구는 문헌연구를 통해 CQI양식을 제안하였고 외부 전문가검증을 통해서 타당성을 확보하였다. 주요 연구 결과는 다음과 같다. 첫째, CQI양식 개발시 수업의 계획, 운영, 결과, 피드백 등 수업의 전 과정을 평가 및 환류 할 수 있도록 문항을 구성하였다. 둘째, 지난학기-당해학기-다음학기 이렇게 3단계로 나누어 종합분석 및 개선 계획을 작성하도록 하여 지속적인 수업의 개선 및 환류의 효과를 얻도록 하였다. 셋째, CQI작성시 수업계획서, 강의평가 결과를 연동하여 교수자의 편리성을 높였다. 넷째, 교수자에게 객관적인 결과(평가도구별 성취도 결과, 강의평가 결과)를 제공하여 이를 토대로 충분한 성찰을 할 수 있도록 하였다. 본 연구는 향후 교과목 CQI 개발에 시사점을 제공하였다는 점에서 의의가 있다.

  • Introduction and application of virtual education has been rapidly increased in these days. A variation of information communication technology has an effect on education in interconnect with network as internet in the world that exceed the limit of time and regional. Computer and network communication technology through the medium of internet make an entrance cyber education as a new education paradigm. It must be affective on learner who have various educational characteristics and requirements. It begins to appear quality, quantity improvements of knowledge and the development of information technology that web based cyber education. This study was conducted to develop the web based education program and to evaluate the effectiveness of learning satisfaction and accomplishment and to compare the cyber lecture system with the traditional lecture system During the second semester of 2001, this study was investigated 317 registered students in a "Food and Culture" class at Kyungwon University. The data were obtained from pre and post-study with self-administered questionnaire. The evaluation and satisfaction score of students who were registered in cyberclass was negative tendency to compare pre with post-test scores, because of insuffciency of computer-aided lecture system. The major problem was inconvenient in checking system for connecting times in cyberclass which was one of evaluation point in final score. Another problem was frequently disconnection during cyber studying and not to concentrate each time in the cyber lecture because of eye fatigue, boring due to less interesting contents than other newly developed web-site. The students was prefer to mix type of the cyber and traditional lecture type class. The result of final score an each class, the score of cyber class (71.36 $\pm$ 22.44) was significantly lower than other groups (mixed type : 76.66 $\pm$ 19.99, traditional type :79.17 $\pm$ 15.72) (p < 0.05). Cyber class was attempted to present a useful and interesting teaching and learning tool which can be applied successfully in a longer term. The result suggest that various teaching and learning strategies should be developed considering the fact that the student learn alone most in time.t in time.

  • 본 연구는 우리나라 교육상황에서 플립드 학습의 잠재력을 시험해 볼 필요성이 있고 특히 이와 가장 잘 접목될 것으로 생각되는 지방대학의 대학 일반영어 교육을 통해서 그 가능성을 탐색하고자 하는 것이다. 지방 중소도시에 소재한 C대학교에서 2017년 2학기에 개설된 영어과 일반영어 수업인 미디어 영어 수업을 대상으로 하여 플립드 수업 방식을 적용하고 그 과정에서 생성되는 질적·양적 자료를 수집하고 분석하여 탐색적 방법으로 대학 일반영어 수업의 개선책을 마련하고자 하는 탐색적 사례연구이다. 효과의 측정을 위한 실험연구가 아니기 때문에 비교반 없이 실험반 한 클라스를 중심으로 연구가 이루어지고 강의평가와 건의문, 중간과 기말고사, 조별 수행평가, 온라인 수업시청률과 학습참여횟수 등과 같은 연구도구에서 나온 자료를 분석하였다. 결과는 중간고사보다는 기말고사의 성적이 유의하게 높았고, 조별 수행평가 점수도 갈수록 나아졌다. 온라인 수업참여율은 수준별로 상집단이 가장 높고, 중집단이 뒤를 잇고 하집단이 그 뒤를 이었다. 그러나 중/하 집단의 경우 플립러닝의 자기주도적 수업 참여율이 높은 경우에는 영어에 많은 향상이 있었다.

  • Meteorological Measurement was performed for evaluation of the horizontal vertical standard deviation $(\sigma_y, \sigma_z)$, surface roughness length and stmospheric stability during the period of March to October 1985 The major results are as follows; 1) The average value of surface roughness length was 144cm at NEPI. 2) In frequency distribution of atmospheric stability, neutral state (D class) was dominent in Seoul (29%) and Pusan (30%). Unstable states (A. B. C. class) were 26% in Seoul and 24% in Pusan. Also, stable states (D. E. F class) were 74% in Seoul and 76% in Pusan. 3) Standard deviations of horizontal ad vertical direction were evaluated as a function of downwind distance and atmospheric stability at NEPI, Jamsil and Pujeondong (Pusan). Standard deviation of horizontal direction was largest at NEPI among 3 areas because of mechanical turbulence resulting from difference of surface roughness length.

  • The objective of this study was to evaluate Environmental microbiology (EM) as a basic course for the environmental engineering program of Korea Maritime University which has been accredited by Accreditation Board for Engineering Education of Korea (ABEEK). Evaluation result of the lecture objectives was more than the average (3.5/5.0). The overall score for learning achievement assessment was more than average level of learning achievement (3.4/5.0). Interestingly, engineering design implementation regarding a specific topic as an extensive learning process has proven to be more effective (3.5/5.0). Some of effective class improvement strategies suggested were to encourage students to participate in the class with self-motivation and accountability: preview and review of the lecture, team presentation in English-speaking settings, and submitting project report written in English. In the future class of EM, test and evaluation of application capability of EM and environmental biotechnology (EB) theories to engineering problem solving should be emphasized.
