학습 속도가 느린 강화학습을 범용적으로 활용할 수 있도록 연구가 활발하게 이루어지고 있다. 사전 지식을 제공해서 학습 속도를 높일 수 있지만, 잘못된 사전 지식을 제공했을 위험이 존재한다. 본 연구는 불확실하거나 잘못된 사전 지식이 학습에 어떤 영향을 미치는지 살펴본다. OpenAI Gym 라이브러리를 이용해서 만든 Gamble 환경, Cliff 환경, 그리고 Maze 환경에서 실험을 진행했다. 그 결과 사전 지식을 통해 에이전트의 행동에 경향성을 부여할 수 있다는 것을 확인했다. 또한, 경로탐색에 있어서 잘못된 사전 지식이 얼마나 학습을 방해하는지 알아보았다.

A self directed learning(SDL) has been identified as an important ability for medical graduates. The purpose of this study was 1) to measure the SDLR of medical students, 2) to compare the relationship among the student perceptions of assessment, preference of instructional methods with SDLR. This study was conducted in 2006 at A University College of Medicine. The instrument applied to this study was SDLR. Korean version of Guglielmino's SDLR for Adults. The $SPSSwin^{(R)}$ program was used to analyze the data and statistics such as correlation. F-test, and Chi square test. Firstly. the mean scores of the SDLR of first, second. fourth year were 114.8, 107.9 and 106.2. This results showed a significant relationship among years (p<.001). Secondly the relationship between the student perceptions of assessment and SDLR was insignificant. The SDLR high scores students had a tendency to favorite "Discussion" and "Bedside teaching". This study found out the problems of medical education to enhance self directed learning ability for medical students. Further study is needed so that suitable instructional methods for medical students can be conducted in curriculum.

The purpose of this paper is to investigate high school students' learning characteristics which revealed in their learning process of limit using GeoGebra. And we are going to analyze effects of teaching of limit using GeoGebra to high school students' interesting and attitudes for mathematics learning. To do this, we selected three high school students as participants and ask them performing limit learning using GeoGebra. We recorded their problem solving process. Through analyzing their problem solving process relate to their solution, we found the followings: First, students did not logically approach based on mathematical properties or given materials, rather showing tendency decide with self-conscious and intuition. Second, it is possible that former reasoning strategies disturb following reasoning in the process of high school students' mathematics learning. Third, learning process of limit using GeoGebra help high school students to identify and correct their errors relate to limit learning. Forth, learning process of limit using GeoGebra positively effects to high school students' interesting and attitudes for mathematics learning.

The purpose of this study is to investigate the evaluation scores among various evaluators such as tutor, peer, and self evaluation, the lenience and central tendency among these various evaluators, and the correlation between evaluation scores among the various evaluators and the paper test score in the Problem-Based Learning (PBL). For the research, tutor, peer, and self evaluations were carried out with PBL effectiveness evaluation tool for the 105 nursing students taking classes using PBL, and paper test was conducted after the PBL class ended. The collected data were analyzed by SPSS WIN (V. 12.0). The study results showed that peer and self evaluation scores were higher than tutor evaluation score. Also lenience and central tendency were higher and stronger in peer and self evaluation than in tutor evaluation. Paper test score had a significant correlation with tutor evaluation score, but not with peer or self evaluation scores.

The purpose of this study is to identify the influences of the reciprocal writing-reflection activities on the mathematical learning of the 2nd grade students by developing a class model using reciprocal writing-reflection activities method as one of the interactive application of manipulative activities, reflective thought and communication activities which are the learning principles of constructivism. We have experimented and investigated to after dividing experimental objects into two group, experimental groups and comparative group, The conclusions of this study are followings. First, reciprocal writing-reflection activities showed significant effects on mathematical achievements of the group with lower achievements in learning. Second, reciprocal writing-reflection activities positively influenced mathematical tendency of the students. Third, the students had positive attitudes in interest, desire and usefulness regarding reciprocal writing-reflection activities. And reciprocal writing- reflection activities are helpful for their reflective thinking and communication activities.

Purpose: The purpose of this study was to use the social network analysis to verify the relationship between the interpersonal disposition and interactive characteristics of nursing college students. Five classes, a total of 117 nursing students were included in the study. Methods: The study interaction network centralization, density and in-degree & out-degree centrality were used as indicators for measuring students' study interaction. Also, the students' interpersonal disposition was measured using verified tool. Results: The results indicated that the ordinary type which gave and took the information generally showed the highest proportions in the study interaction network. Also, the empathic-acceptable tendency of social relation domain showed the highest proportions in the interpersonal disposition. Moreover, the students who play the isolate and the carrier role in the study interaction network had no relation with the expression tendency, and the transmitter role play students had no relation with the role tendency. Conclusion: Based on the results, the tutors should consider the students' interpersonal relationship disposition when implementing the instructional strategy in PBL curriculum.

In this paper, we propose an intelligent navigation system that selects a proper route for user and applies the user's preference, user's tendency and environmental state estimated by driving information of user and road state. The system uses data of sensors, navigation and intelligent transport system to evaluate conditions of roads and it considers state of user's emotion. The system also uses soft-computing method to infer and learn the user's preference and tendency. We verify the proposed algorithm by computer simulation.

From the biopsychological point of view,learning could be defined as the processes to transfer the information that we obtain from environment to the neural circuits in the brain.In the studies to determine the biological substrates of learning and memory,there was a remarkable effort to identify neural circuits related with a specific type of learning and to describe the mechanixm of neural plasticity of learning and memory,under the assumption that the memory orinformation may be stored as a modificationof neural synapes in the central nerviys system.On the other hand,there was a different kind of tendency to analyze the mechanism of interactions between neural substrates involved in learning and memory,under the assumption that a specific information may be represented in the patterns of comples neural network of the central nervous system.The present review,in the former position.focused on the research methods and the chracteristics and finding of the investigations employing animal model systems to indentify the essential site of engram for learning and memory.Specifically,the review presents major advances in ourunderstanding of the memory trace circuit for a specific type of learning,with the use of animal model system,the detemination of the critical lodi of neuaral plastic chabges In learing abd memory,and the neurophysiological an biocemical mechanixms of the neural modifia by learint.

In order to make an efficient prescription and cope with dementia, learning and memory functions of Sprague-Dawley model rats were tested with Morris water maze. And to evaluate the effect of the sample drug(CHM) on choline acetyltranferase and acetylcholine esterase, immunoreactive measurement and enzymatic activity measuring were carried out. Rats were injected with ibotenic acid through hippocampus CA1 and CA3 area. The results are as following. CHM improves the learning ability in the acquisition test and memory function in the retention test significantly. And CHM increases the level of AChE which is resolving acetylcholine. Though it doesn't increase the level of ChAT significantly which is synthesizing acetylcholine, but it shows the tendency of increase. So these results show that CHM improve the cholinergic catabolism and anabolism, and the increment of metabolic activity of cholinergic system. Thus it can be concluded that CHM will be helpful to cholinergic brain disease induced by primary or senile reduction of acetylcholine secretive activity.
