본 논문은 불완전한 데이터를 처리하기 위해 2가지의 서로 다른 기법과 이를 학습하는 알고리즘을 소개한다. 첫째방법은 손실변수가 가질 수 있는 균등한 확률로 손실값을 할당하여 불완전한 데이터를 처리하고, SVM 알고리즘으로 이 데이터를 학습하는 것이다. 이 기법은 임의의 변수에 손실 값의 빈도가 높을수록 엔트로피가 높도록 하여 이 변수가 결정트리에서 선택되지 않도록 하는 것이다. 이 방법은 손실 변수에 남아있는 정보를 모두 무시하고 새로운 값을 할당한다는 특징이 있다. 이에 반해 새로운 방법은 손실 값을 제외하고 남아있는 정보로 엔트로피 확률을 구하고 이를 손실 변수의 추정 값으로 사용하는 것이다. 즉, 불완전한 학습데이터로부터 소실되지 않은 많은 정보들을 이용해 소실된 일부 정보를 복구하고 딥러닝을 이용해 학습한다. 이 2가지 방법은 학습데이터에서 차례로 변수 하나를 선택하고, 이 변수에 손실된 데이터의 비율을 달리하면서 서로 다른 측정값들의 결과들과 반복적으로 비교함으로써 성능을 측정한다.

In order to learn in dynamic environments, reinforcement learning algorithms like Q-learning, TD(0)-learning, TD(λ)-learning have been proposed. however, most of them have a drawback of very slow learning because the reinforcement value is given when they reach their goal state. In this thesis, we have proposed a reinforcement learning method that can approximate fast to the goal state in maze environments. The proposed reinforcement learning method is separated into global learning and local learning, and then it executes learning. Global learning is a learning that uses the replacing eligibility trace method to search the goal state. In local learning, it propagates the goal state value that has been searched through global learning to neighboring sates, and then searches goal state in neighboring states. we can show through experiments that the reinforcement learning method proposed in this thesis can find out an optimal solution faster than other reinforcement learning methods like Q-learning, TD(o)learning and TD(λ)-learning.

Mathematical argument has been given much attention in the research literature as a mediating construct between reasoning and proof. However, there have been relatively less efforts made in the research that examined the nature of empirical arguments represented in textbooks and how students perceive them as proofs. Cases of point include Intermediate Value Theorem [IVT] and Maximum-Minimum theorem [MMT] in grade 11 in Korea. In this study, using Toulmin's framework (1958), the author analyzed the substance of the empirical arguments provided for both MMT and IVT to draw comparisons between the nature of datum, claims, and warrants among empirical arguments offered in textbooks. Also, an online survey was administered to learn about how students view as proofs the empirical arguments provided for MMT and IVT. Results indicate that nearly half of students tended to accept the empirical arguments as proofs. Implications are discussed to suggest alternative approaches for teaching MMT and IVT.

As a measure of the center of data, arithmetical mean, median, mode, harmonic mean and geometric mean are generally used. Students must learn qualitative aspect of average values as well as its calculation for its adequate use. As the result of the learning, they should be able to select the appropriate average value according to the characteristic of data and problem context. For this object, the historical origin and visual interpretation of average values were introduced in this paper. And to help teaching several meanings of average values, several examples including context were suggested.

우리나라 학생들은 수학의 인지적 영역에서는 높은 성취를 보이지만 정의적 영역에서는 현저히 낮은 성취를 나타내고 있다. 본 논문에서는 수학의 정의적 영역 중 수학의 가치 교육 문제에 대하여 폴라니의 인식론을 바탕으로 논하였다. 폴라니의 인식론에서는 개인적 지식과 지식의 암묵적 차원을 강조한다. 그는 수학의 추상성, 일반성을 강조하였고, 수학의 발전은 공리적, 형식적 측면보다는 지적 아름다움과 열정에 의하여 안내된다고 하였다. 이러한 폴라니의 인식론의 관점에서 볼 때, 수학의 유용성, 실용성 등의 언어적 전달이나 표면적인 흥미 유발을 위한 활동은 본질적으로 가치 교육 및 수학 공부의 내재적 동기 부여에 한계가 있다. 수학 공부의 가치는 적절한 수학 문제에로의 몰입과 긴장, 그리고 문제가 해결되면서 따르는 기쁨, 환희를 맛보며 몸으로 체득하면서 배워야 하는 것이다.

Recently, the educational community has attempted to implement the theory of multiple intelligences. In approaching multiple intelligences, teachers have applied the same structural approach which has been so successful with cooperative learning. Cooperative learning is easy to learn and implement, fun for teachers and students, and produce profoundly positive outcomes along a remarkable number of dimensions. Different structures are designed for different outcomes, including enhanced mastery of subject matter, improved thinking skills, team building, class building, development of social character and social skills, communication skills, classroom management, classroom discipline, and development of and engagement of each of the multiple intelligences. Cooperative learning is becoming an increasingly popular teaching strategy. In this study, it is aimed to clarify the application of cooperative learning in health education. Cooperative Learning in health education enhances student learning by: 1) providing a shared cognitive set of information between students, 2) motivating students to learn the material, 3) ensuring that students construct their own health knowledge, 4) providing formative feedback, 5) developing social and health group skills necessary for success outside the classroom, and 6) promoting positive interaction between members of different cultural and socio-economic groups. Cooperative Learning structures and techniques in health education are following. Flash Card, Focused Listing, Structured Problem-solving, Paired Annotations, Structured Learning Team Group Roles, Send-A-Problem, Value Line, Uncommon Commonalities, Team Expectations, Double Entry Journal, Guided Reciprocal Peer Questioning, What if. Because the purpose of health education is the practice, therefore health specialists have to guide powerful and effective teaching method The application of cooperative learning in health education may improve its effectiveness.

Purpose : The patients who have Supraspinatus tendinitis, Lateral epicondylitis, Achilles tendinitis are our targets, so we want to know their opinions in order to take Sono-graphic tests and to study utility value of Sono-graphic. Object and Methods : The case of 30 patients with Tendinitis results, we classified with three categories, Supraspinatus tendinitis, Lateral epicondylitis and Achilles tendinitis. Case by case, before medical treatment, we executed the inspections which are Sound side and Affected side. After 4 weeks of medical treatment, we executed the inspection which is Sono-graphic. Objectively comparing with Sono-graphic, we measured VAS(Visual Analog Scale) before and after physical therapy. Results : We could learn that VAS (Visual Analog Scale) and Sono-graphic wore decreased about changing the lesion area of each disease. For example, Supraspinatus tendinitis is from case 1 and case 2, Lateral epicondylitis is from case 8, case 9 and case 10, Achilles tendinitis is from case 16, case 17 and case 18. Conclusion : About organization of complicated anatomy, we could learn general ideas about Supraspinatus tendinitis, Lateral epicondylitis, Achilles tendinitis. And finally the results which appeared between the decrements of VAS and Sono-graphic are similar.

The goals of moral education according to the 7th educational curriculum are (1) to learn the basic life custom and ethical norms necessary to desirable life, (2) to develop the judgment to solve desirably and practically the ethical matters in daily life, (3) to develop the sound citizenship, national identity and consciousness, and the consciousness of world peace and mankind's mutual prosperity, and (4) to develop the ethical propensity to practice the ideal and principle of life systematically Based on the goals in the above, the following can be established as goals of environmental education possible: (1) to learn judgment to solve practically the environmental problems in the society with their ethical understanding, and (2) to recognize that environmental consciousness is the basic necessity of sound citizenship and national identity and consciousness, and mankind's mutual prosperity, and to have attitudes to practice environmental preservation in daily life. Like these, the intellectual aspect, the affective aspect, and the active aspect can be established in the environmental education in the ethics education keeping their balance. In order to achieve its goals, the contents of ethics subject are organized largely with 4 domains: (1) individual life, (2) home life, life with neighbors, and school life, (3) social life, and (4) national life. Among these, environmental education is mainly included in the domain of social life. These contents concerning environmental education take 22 (32.4%) out of the whole 68 teaching factors which are taught in the ethics subject from the 3rd grade to 10th grade. These 22 environmental teaching factors are mainly related to environmental ethics, environmental preservation and measures, and sound consumption life. Classified according to each goal, the environmental contents in the 7th curriculum for ethics subject put emphasis on environmental value and attitudes, action and participation, and information and knowledge. Therefore, the recommendable teaching and learning method for the environmental education in ethics subject is to motivate students' practice or to make them practice in person. For example, role-play model, value-conflict model, group study model can be applied according to the topics of environmental education.
