A purpose of this study is degree of recognition and consciousness investigation about a satisfaction duty before admission about a school subject of some academic dental hygiene students. From responses to individual written survey questionnaires answered by 608 students who are studying Dental Hygiene at colleges in Mokpo, Iksan, Gangneung. The following are the results regarding their satisfaction levels with their majors and their interest in working abroad: 1. Regarding the motivating factors to major in Dental Hygiene, most students(51.3%), particularly most freshmen(57.3%), have chosen this major because of more job opportunities than students with other majors. The most common source of information in choosing majors is the Internet(30.8%). 2. Most students do not want to change their majors even if they are provided with the chance to do so(65.5%). They are in general satisfied with their studies. The result shows that the Dental Hygiene majors are positive toward their major. 3. Most students will choose their jobs by their own choices(40.6%), and the most important factor in their choices is the opportunity of self-growth and development(33.1%). The survey results show that the Dental Hygiene students value their own decisions and self-realization. 4. Showed the difference that as a result of having seen a knowledge degree advance a school subject of major in Dental Hygiene by a school year and ash students, an admission motive, relevance of an information acquisition path, all noted. 5. And were able to see the difference that noted in an adviser, work selection bases in case of work selection whether or not there was a dissatisfaction reason about a major and a criminal record.

수학 교수학습은 수리 논리적인 수학적 사고의 신장에 초점을 맞추어왔다. 그러나 최근 '서사적 방향 전환'과 함께 수학교육의 분야에서도 이야기의 활용에 대한 관심이 높아지고 있다. 본 연구에서는 서사학, Bruner의 논의, 교육 분야에서 내러티브에 대한 논의 등을 바탕으로, 만들어낸 이야기 또는 다른 사람이 겪은 이야기로서의 '이야기'와 저자 또는 화자가 경험한 수학적 사실들의 스토리 형식을 갖춘 재현으로서의 '수학 내러티브'를 구분하고, 수학 내러티브와 수학적 사실들에 대한 내러티브 사고 양식의 적용을 통해 인지적 의미와 정서적 의미를 구성하는 과정을 논의하였다. 이를 통해 수학 내러티브의 활용이 이야기 활용의 제한점을 보완하는 방식으로 수학에 대한 흥미와 의미를 형성시킬 수 있음을 논의하였다. 끝으로 수학 내러티브의 활용이 수학 교과와 학습자의 통합에 기여할 수 있음을 논의하고 이러한 관점에서 수학 교수학습을 재음미하였다.

European Commission drafted and proposed the Common European Sales Law(CESL) to the European Parliament for the realization of a uniform set of international private law rules within the EU internal market. Since its purpose is for free international commercial activities for the sale of goods, for the supply of digital content and for related services, it was proposed to enable EU Member States to adopt or supplement as their substantive law according to their options. This study is relate to the legal bases on termination of a contract under CESL, they are composed of three parts: damages and interest, restitution and prescription. Damages and interest are divided into damages, general provisions on interest on late payments, and late payment by traders. Damages are explained by dividing into right to damages, general measure of damages, foreseeability of loss, loss attributable to creditor, reduction of loss, substitute transaction, and current price. Restitution is described by dividing into restitution on revocation, payment for monetary value, payment for use and interest on money received, compensation for expenditure and equitable modification. Prescription is explained by dividing into general provisions, periods of prescription and their commencement and extension of periods of prescription. General provisions explain right subject to prescription into a right to enforce performance of an obligation and any right ancillary to such a right. Regarding period of prescription, the short one is two years and the long one is ten years. However, in the case of a right to damages for personal injuries, period of prescription for such right is thirty years. Regarding commencement, the short one begins to run from the time when the creditor has become, or could be expected to have become, aware of the facts as a result of which the right can be exercised, while the long one begins to run from the time when the debtor has to perform. However, in the case of a right to damages, the CESL clarifies that it begins to run from the time of the act which gives rise the right.

Various data and methods are necessary to help students understand the science subject, and have interest in it. Most students like cartoons, and more easily memorize their contents. The purpose of this study was to verify the effects of science cartoon reading on the academic achiements, the levels of interests in science and scientific attitudes of elementary students The study subjects were four classes of the 6th grade of G elementary school in U city. Two classes were experimental group and the others were comparison group. The students of the experimental classes were encouraged to read science cartoon related to class contents at the beginning and ending for 5 minutes respectively in instructional time. And those of the comparison classes received general science lesson. The results of this study were as follows. First, the experimental classes encouraged to read science cartoon marked higher average score than comparison classes in post-test and the difference was meaningful (p<.05). This meant science cartoon reading treatment had the effect of improvement of the levels of interest in science of student. Second, the experimental classes marked higher average score than comparison classes in post-test but didn't show meaningful difference. This meant science cartoon reading treatment didn't have the effect of improvement of academic achievement of students in our study. Third, the experimental classes marked higher average score than comparison classes in post-test and showed the meaningful difference(p<.05). This meant science cartoon reading treatment had the effect of improvement of scientific attitudes of students. From the results thus far, we could tell that science cartoon reading had positive effects on the levels of interest in science and scientific attitudes of students in our study.

Recently, parents and teachers consider physical education as a minor subject for students in elementary and secondary schools. Physical education performance has become increasingly significant as parents and schools pay more attention to physical schooling. The sports mining with distribution analysis model considers different factors, including the games, comments, conversations, and connection made on numerous sports interests. Using different machine learning/deep learning approach, children's athletic and academic interests can be tracked over the course of their academic lives. There have been a number of studies that have focused on predicting the success of students in higher education. Sports interest prediction research at the secondary level is uncommon, but the secondary level is often used as a benchmark to describe students' educational development at higher levels. An Automated Student Interest Prediction on Sports Mining using DL Based Bi-directional Long Short-Term Memory model (BiLSTM) is presented in this article. Pre-processing of data, interest classification, and parameter tweaking are all the essential operations of the proposed model. Initially, data augmentation is used to expand the dataset's size. Secondly, a BiLSTM model is used to predict and classify user interests. Adagrad optimizer is employed for hyperparameter optimization. In order to test the model's performance, a dataset is used and the results are analysed using precision, recall, accuracy and F-measure. The proposed model achieved 95% accuracy on 400^th instances, where the existing techniques achieved 93.20% accuracy for the same. The proposed model achieved 95% of accuracy and precision for 60%-40% data, where the existing models achieved 93% for accuracy and precision.

본 연구에서는 성격유형과 흥미유형에 따른 독서 감상문에 나타난 독서에 대한 반응의 차이를 탐구하였다. 이를 위해 대전의 D과학고등학교 3학년 학생 81명을 대상으로 성격유형분석 데이터, 흥미유형분석 데이터, 교과독서 활동으로 작성된 독서 감상문 데이터를 수집하였다. 수집된 독서 감상문의 토픽 분석을 수행하고, 성격유형(사고형, 감정형)과 흥미유형(탐구형, 탐구형 외)에 따른 독서 감상문의 토픽 발현 확률을 통계적으로 검증하였다. 이어서 키워드 네트워크 분석을 통해 단어들의 개념 연결 구조를 측정하고, 중심성 지표를 통해 토픽모델링의 분석 결과를 보완하였다. 연구 결과, 토픽 회귀분석을 통해 토픽2(이해와 공부)와 토픽3(읽기와 사고)에서 사고형(T)과 감정형(F) 간에 통계적으로 유의한 차이를 확인할 수 있었으며, 토픽2(이해와 공부)에서 탐구형과 탐구형 외 간에 통계적으로 유의한 차이가 확인되었다. 본 연구의 결과는 맞춤형 도서 추천이나 개인화를 고려한 독서교육의 기초자료로 활용될 수 있을 것이다.

In recent years, there has been a renewed interest in the BLDC motor as a research subject. In this paper we inspect sources of the torque ripple, which is one of the elements causing performance depreciation of BLDC motors. Based on the inspected sources of the torque ripple, feedforward compensation methods are proposed to reduce the size of torque ripple. The effectiveness of the proposed methods is verified with experiments.
