편입력 기능을 창작한 시스템의 문자입력 기능에서 사용자들의 다양한 형태의 필기문자를 인식하여 사용자의 만족을 극대화 시킬 수 잇는 고성능의 인식기를 만들기 위해서는 상황과 장소에 따라서 변하는 필기형태를 학습할 수 있는 다이나믹한 인식기 개발이 절대적으로 필요하다고 판단된다. 또한 국제 경쟁력을 갖기 위해서는 사용자의 국적(nationality)에 따라 다양한 자종을 인식할 수 잇는 기능이 있어야 한다. 따라서 본 논문에서는 다양한 사용자의 요구를 만족시키기 위하여 인식기 설계시 필요한 design issues와 philosophy를 제시하고, 이를 기초로 학습기능, 국제화, 소형화의 특징을 갖는 학습기능 다중언어(multilingual) 인식기 설계 방법을 제안하고자 한다.

체육교과에서 맨손 체조를 구성하는 수업은 기존의 자료 제시 형태의 컴퓨터 활용 수업에서는 일제식 수업이나 학습 목표를 달성하지 못한 흥미 위주의 수업으로 흐르기 쉽다. 그래서 맨손 체조에 관련된 제 7차 교육과정 내의 학습 내용을 살펴보고, 학습자가 자신에게 필요한 맨손 체조를 직접 구성하는 프로그램을 설계하였다. 여러 가지 동작을 익히고, 그 동작의 효과를 학습한 뒤, 적절한 동작을 연결하여 맨손 체조를 구성하는 프로그램으로써 평가를 통해 피드백이 가능하도록 한다. 이 프로그램을 통해 맨손 체조 구성 학습에 대한 학습자의 동기를 유발하는 동시에 학습 목표에 충분히 도달하여 학습자의 자기주도적 능력을 신장시키고자 한다.

The 7th curriculum which was administered to high school science courses from 2002 asked for a revel specific curriculum. But those curriculums were not developed. The purpose of this research was to develop a level specific curriculum for high school science courses, apply it to high school science courses, and then investigate the effects of this curriculum through the change in attitude towards science and perception towards level specific curriculum. The results are as follows. 1) The two types of level specific curriculum for high school science course was developed. In the first type, the level specific curriculum instruction was conducted in the same class whereas, instruction was divided in the second one, according to the students' intellectual levels. 2) Result on the perception of the test showed that developed level specific curriculum was ineffective in changing the students' attitude towards science, even though they recognized the importance of the curriculum. This was because the students perceive science as a difficult and uninteresting subject.

The purpose of this study was to explore the effect of learning effects by type on college life satisfaction for college students. A total of 250 copies of the survey were distributed, and a total of 219 copies were used for analysis except for 31 copies, excluding questionnaires with many poor or missing questions. The learning effect according to the socio-demographic characteristics of college students showed a significant difference in the form of cohabitation, and it was found that the learning effect was high in the order of alone and friends. Perceptual learning showed significant differences in the form of cohabitation, and it was found that perception learning was high in the order of alone, friends, and seniors and juniors. Cognitive learning showed significant differences in the form of cohabitation, and cognitive learning was found to be high in the order of friends, alone, and seniors and juniors. There was a significant difference in college satisfaction with the type of cohabitation, and it was found that college satisfaction was high in the order of alone, seniors and juniors, and friends. Finally, the higher the discovery learning, perceptual learning, and cognitive learning, the higher the college life satisfaction, and among them, discovery learning was found to have a great influence on college life satisfaction. Overall, the university should provide an environment where students can freely move between individuals and communities and live their university life. In addition, in preparation for problems occurring in the community, it will be necessary to activate the related counseling room.

A project learning is the model to solve the problem in cooperation with the members of a group. The purpose of this study is to make a new learning model using a web on the traditional project learning model. A Web has the proper nature for students to make their learning environment, so that this study embodied Student Directed Web based project learning system to allow them to expand their abilities. All action of students, that is, suggesting main subject, making plans, activating and adjusting them, and evaluation can be happened in this system. According to the result of applying the system, participants in Students Directed Web based Project Learning intend to implement learning activities more positively, affirmatively and cooperatively than the existing ones.

SVDD의 scale prob1em을 해결하기 위하여, 학습 데이터를 sub-groupings하여 group 단위로 SVDD를 통해 학습함으로써 학습 시간을 줄이는, K-means clustering을 이용한 SVDD 방범(KMSVDD)이 제안되었다. 하지만 KMSVDD는 K-means clustering 알고리즘의 본질상 최적의 K값을 정하기 힘들다는 문제와, 동일한 데이터를 학습할지라도 clustered group이 램덤하게 형성되기 때문에 매번 학습의 결과가 달라지는 문제점이 있었다. 또한 데이터의 분포 상태와 관계없이 무조건 타원(dlliptic) 형태의 K개의 cluster로 나누기 때문에 각각의 나눠진 cluster들은 데이터 분포에 대한 특징을 나타내기 힘들게 된다. 이러한 문제점을 해결하기 위하여 본 논문에서는 데이터 분포에서 mode를 먼저 찾은 후 이 mode를 기준으로 clustering하는 Mean Shift clustering 방법을 이용한 SVDD를 제안하고자 한다. 제안된 알고리즘은 KMSVDD와 비교해 데이터 학습 속도에서는 큰 차이가 없으면서도 데이터의 분포 상태를 고려한 형태로 clustering 한 sub-group을 학습하므로 학습의 정확도가 일정하게 되며, 각각의 cluster는 데이터 분표의 특징을 포함하는 효과가 있다. 또한 Mean Shift Kernel의 bandwidth의 결정은 K-Means의 K와는 달리 어느 정도 여유를 갖고 결정되어도 학습 결과에는 차이가 없다. 다양한 데이터들을 이용한 모의실험을 통하여 위의 내용들을 검증하도록 한다.

The on-line and mobile communication technologies provide an environment to make users share information on the rove. However learning on a file received from on-line or mobile internet environment is able to read only, According to this, users cannot use various learning methods to make multimedia contents for learning like coloring and underlining considerable parts. Also, in case of storing, it cannot be stored in a standard file format HTML. Therefore, in this paper, we suggest a new learning platform to be able to change text contents in a web documents and implement a prototype system to process learning system in on-line environment

Mathematical Communication ability can be more developed through sharing thoughts with others. Therefore when we instruct students in math, it is very important for teachers to provide them with opportunity to communicate mathematically. So this study provided open-ended problems in small-group collaborative learning. And we analyzed students' mathematical communication focused on the student's level of understanding. Furthermore, to improve students' mathematical communication ability, this study tries to attract the factors that we should consider the exact date for inserting the open-ended problems into a course of math and the student's level of understanding for selecting suitable open-ended problems.

A project-based learning is the model to solve the problem in cooperation with the members of group. The purpose of this study is to make level learning system using a web on the project-based learning. A Web has the proper nature for students to make their learning environment, so that this study embodied student directed to allow them to expand their abilites. All action of students, that is, suggesting main subject, making plans, activating and adjusting them, and evaluation can be happened in this system. Acoording to the result of applying the system, participants in students Directed level Web based Project Learning intend to implement learning activitis more positively, directly, cooperatively than the existing ones.
