  • 본 연구는 현재 전국의 모든 영재교육 기관에서 영재 학생을 선발할 때 적용하고 있는 관찰 추천 방법에 활용 가능한 영재 행동 특성 체크리스트를 개발하는 것을 목적으로 하고 있다. 기존 영재 행동 특성 체크리스트들은 제시한 문항들이 학교생활을 통해 관찰이 불가능하거나 애매한 항목들을 다수 포함하고 있거나, 영재 행동 특성으로서 그 중요도가 떨어지거나, 유사한 특성들이 반복되거나 혹은 다수의 문항으로 인해 실제 관찰 추천에서 활용도가 떨어지는 등의 문제점들이 지속적으로 제기되어 왔다. 이에 본 척도는 기존 연구에서 제시하고 있는 영재 행동 특성 요인들을 바탕으로 학교 현장에서 학생들을 직접 지도하고 있는 영재 교사들에 의해 '실제로' 관찰 가능성이 높은 영재 행동 특성과 각 특성들의 '중요도'를 반영했다는 데 의의가 있다. 본 척도는 현장의 영재 지도교사들을 대상으로 영재 행동 특성 요인과 구체적인 행동 양상에 대한 개방형 설문을 받고, 이를 전문가 그룹의 검토와 예비 검사, 본 검사, 확인적 요인 분석의 과정을 통해 개발하였다. 관찰 가능성과 중요도란 기준 적용으로 개발된 체크리스트는 일부 요인들을 제거하여 최종적으로 10개의 하위요인(논리적 사고, 높은 성취도, 독창성, 완벽주의, 창의적문제해결력, 호기심, 과제집착력, 의사소통 능력, 창의성, 활동성(열정))으로 구성되었으며, 각 요인별로 2~4개 문항이 제시되어 총 32개의 행동 특성 문항으로 개발되었다. 최종 32문항에 대한 내적합치도(${\alpha}$)와 문항-총점 상관을 분석한 결과 모두 양호한 값을 보여 영재 행동 특성 척도의 각 문항이 해당 구인을 일관성 있게 측정하는 것으로 분석되었다. 또한 영재 행동 특성 체크리스트에 대한 확인적 요인 분석 결과 모든 문항들이 각 하위 요인에 높게 부하되어 영재 행동 특성을 측정하는 체크리스트로 적합하며, 현장에서 초등학교 영재 학생들을 관찰 추천할 때 활용할 수 있음을 시사하고 있다.

  • In the advent of the twenty-first century, human beings began to closely interact with technology. Today, technology is developing, and as a result, the world wide web (www) has a very important place on the Internet and the significant task is fulfilled by Web services. A lot of Web services are available on the Internet and, therefore, it is difficult to find matching Web services among the available Web services. The recommendation systems can help in fixing this problem. In this paper, our observation was based on the recommended method such as the collaborative filtering (CF) technique which faces some failure from the data sparsity and the cold-start problems. To overcome these problems, we first applied an ontology-based clustering and then the k-nearest neighbor (KNN) algorithm for each separate cluster group that effectively increased the data density using the past user interests. Then, user ratings were predicted based on the model-based approach, such as singular value decomposition (SVD) and the predictions used for the recommendation. The evaluation results showed that our proposed approach has a less prediction error rate with high accuracy after analyzing the existing recommendation methods.

  • 이 연구의 목적은 초등 과학 영재 학생들을 대상으로 과학박물관 탐방학습을 실시하여 관찰의 유형을 분류하고 이를 분석하였다. 이를 위해 과학 영재 학생 10명을 선정하여 탐방학습이 진행되는 동안 일어나는 관찰을 언어로 표현하도록 하여 모든 관찰 내용과 대화를 녹음하였다. 그 결과는 다음과 같다. 인지적 측면에서는 응답의 빈도가 높았고 자신의 의견을 배제하고 전시물과 관련하여 질문하고 응답하는 빈도가 높았으며, 정의적 측면에서는 권유의 빈도수가 가장 많았다. 관찰의 유형을 분류하고 이를 분석한 결과에서는 단수의 관찰 대상 전체를 시간 독립적으로 관찰하는 빈도가 높고, 시각을 사용하여 조작을 하지 않고 정성적인 방법으로 관찰하는 빈도가 높았다. 따라서 질문을 통한 언어적 상호작용은 관찰의 빈도와 다양성에 긍정적인 영향을 주며, 과학박물관 탐방학습에서 과학 영재 학생들의 다양한 관찰을 유도하기 위해서는 프로젝트 학습과 같은 특정 전시관이나 전시물을 학생이 직접 선택하여 집중 탐구할 수 있는 시간이나 학습지를 마련하면 더 효과적인 관찰 학습이 이루어질 수 있을 것으로 보인다.

  • A number of middle and high school students are selected at the Korea Astronomy Olympiad (KAO) in every year. In the first stage of the selection, the resume, school transcript, and recommendation letters from teachers are referred. In the second stage, after video lectures and weekend observation classes, students are tested with on-line homeworks, and interviewed through internet. For 118 students who have gone through the second stage of the 2012 KAO, we have conducted a questionnaire survey, which asks the students the motivation and preparation for the KAO. The survey has also included inquiries for the selection process and education program of the 2012 KAO; the replies will be used as feedbacks for the next year's KAO. The survey has revealed that the first stage worked well, while the second stage needs to be improved in terms of fairness and objectivity. We have found that most students received private tutorings for the KAO, so we suggest efforts should be made for students to be able to prepare the KAO without receiving private tutorings.

  • Objective : This study was to evaluate the single dose toxicity of Bojungikki-tang(Buzhongyiqi-tang, BJIKT) in male and female mice. Method : Aqueous extracts of BJIKT were administered to female and male ICR mice as an oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration (KFDA) Guidelines. Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation during 14 days after dosing, upon necropsy ; organ weight and histopathology of 12 principle organs were examined. Results : we could not find any mortality, clinical signs, and changes in the body and organ weight. In addition, no BJIKT-treatment related abnormal gross findings and changes in histopathology of principle organs were detected except for some sporadic accidental findings. Conclusion : The results obtained in this study suggest that the 50% lethal dose and approximate lethal dose of BJIKT aqueous extracts in both female and male mice were considered as over 2,000 mg/kg, the limited highest dosage recommended by KFDA Guidelines, and can be safety used in clinics.

  • The object of this study was two. One was if Polygonati Rhizoma preparata had a benzo(a)pyrene, the other was to evaluate the single dose toxicity of 9 repetitive steaming and fermenting processed Polygonati Rhizoma, dried root parts of Polygonati Rhozoma preparata extract, in male and female mice. We measured a content of benzo(a)pyrene in Polygonati Rhozoma preparata using a method with HPLC/FLD. And for single dose toxicity, aqueous extracts of Polygonati Rhozoma preparata (EPP; Yield = 35.4 %) was administered to female and male ICR mice as an oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration (KFDA) Guidelines. Animals were monitored for the mortality and changes in body weight, clinical signs and gross observation during 14 days after dosing, upon necropsy; organ weight and histopathology of 12 principle organs were examined. As results, we could not find any mortality, clinical signs, and changes in the body and organ weight except for slight soft feces sporadically detected in EPP treated male mice at 1 day after administration. In addition, no EPP-treatment related abnormal gross findings and changes in histopathology of principle organs were detected except for some sporadic accidental findings. The results obtained in this study suggest that benzo(a)pyrene was not existed in Polygonati Rhozoma preparata and the 50% lethal dose and approximate lethal dose of EPP aqueous extracts in both female and male mice were considered as over 2,000 mg/kg, the limited highest dosage recommended by KFDA Guidelines. However, it also observed that the possibilities of digestive disorders, like soft feces when administered over 500 mg/kg of EPP aqueous extracts in the present study.

  • Objectives : The purpose of this study was to propose appropriate strategic directions and road maps for successful achievement of programs preventing winter disease in the summer. Methods : Details on programs preventing winter disease in the summer such as clear concept, theoretical basis, current status, intervention or available prescriptions and indication/contraindication/caution were prepared through the related journal review, upon which an observational study was devised and done for simulation to find out even a trivial problem and to guarantee the safety beforehand. The experimental group was divided into 5 groups by the size of pill and the way ginger is treated; 1cm pill with ginger group, 3cm pill group without ginger, 3cm pill group dipped into ginger, 3cm pill group applying ginger to acupoints and 3cm pill group with ginger Results 1. program preventing winter disease in the summer was defined as representative winter diseases such as common cold, influenza, chronic asthma, chronic bronchitis, allergic rhinitis, emphysema, chronic gastritis and rheumatoid arthritis, and preventive care in the summer, reinforcing deficient yang qi of five viscera by using exuberant yang qi from summer heat. 2. It was based upon historically established theories which is 'nourishing yang qi in the spring and summer', 'long summer, namely rainy spell in the summer overwhelms the winter, because of earth winning water according to the five phases theory' and 'To replenish yang qi is major principle to treat winter diseases, which can be most appropriately and timely applied to the patient with deficient yang qi of five viscera inherently, especially in the three dog days of the summer, because of exuberant exterior yang qi and deficient interior yang qi in the five viscera'. 3. In the adjacent China and Taiwan, acupoint applying method in the three dog days named 'San Fu Tie' have been stirring a boom throughout the nation, in which Xiaochuan Gao was used as a basic prescription and it mainly was applied at bilateral $BL_{13}$, $_{15}$ and $_{17}$ for about 4 hours. As far as domestic current status, the necessity of adopting the above method prior to Herbal formula was also recognised, because not a few koreans have apprehension for the safety of it including medicinal herbs and are reluctant to take it any more due to negative advertisement of narrow minded doctors' association. 4. Indication of acupoint applying method in the three dog days included most of winter diseases such as common cold, influenza, chronic asthma, chronic bronchitis, allergic rhinitis, emphysema, chronic gastritis. contraindication was pregnant woman and the weak such as infants and the old. More attention was paid to grasp firmly the normal reaction following the treatment for preventing side effect and teasing blister. recommendation was also given to abstain from food inducing phlegm and dampness such as meat, shrimp and crab as well as cold drinks and foods 5. In the simulation observational study based upon the above findings following review the related articles, no blister was shown on the acupoints icluding bilateral $BL_{13}$, $_{15}$ and $_{17}$ in every experimental group during 24hr observation following the acupoint applying treatment with pills made by modified and devised prescription. At 4 hr, the effectiveness of it reached a peak showing redness and mild tenderness and there is little difference between groups 3cm pills groups regardless of the way ginger was treated. abdominal distention and growling was found in all the volunteers during the treatment at CV 8. Strategic directions and road maps : Through successful fulfillment of the program preventing winter disease in the summer, Korean traditional medicine should be integrated into mainstream national health care services. Cultural access was thought to be as important as Scientific EBM approach. First of all, To evoke potential cultural homogeneity from campaigns and press advertisement was needed for promoting public awareness about preventing winter disease in the summer by enhancing immunity via acupoint applying treatment in the three dog days, and then indigenous name as Sambokcheop, protocol, Clinical Research Form for data collection of it should be developed and prepared. Once the first step was taken this summer, through a thorough data collection and scrutinized scientific evaluation, drawbacks should be compensted for and the efficacy and safety should be substantiated.
