김판수,조지영 부산교육대학교 교육대학원 2004 논문집 Vol.6 No.-

본 연구는 수학교과의 학습에 방해가 되고 있는 요인을 조사·분석함으로써 학생들의 수학 교과에 대한 부적응 상황을 진단하여 학생들의 수학 부진을 줄이고 나아가 교수-학습 개선에 도움을 주고자 하는데 목적을 둔다. 이를 위해 초등학교 5학년을 대상으로 우선 수학 학습 부진 학생들의 인식을 조사, 분석하였다. 또한 수학 학습 부진아를 지도할 때 학생들이 어려워하는 학습 내용을 사전에 파악하는 것이 학습부진을 줄일 수 있는 중요한 수단으로 보고 4학년 수학 단원 평가를 실시하여 이들이 어떤 내용을 잘 이해하지 못하는지를 분석하였다. 그 결과 수학 학습 부진 학생들은 수학 교과에 대해 부정적으로 생각하고 있었으며, 이들이 어려워하는 수학 내용은 다단계 사고를 요하는 개념, 논리적 연역적으로 추론을 요하는 개념, 문제해결이었다. 그 중에서도 특히 사고를 요하는 문제해결을 어려워하는 것으로 나타났다. This study sets out to investigate underachieved fifth graders in mathematics in terms of the understanding and learning state of mathematics and to help mathematics underachievers by providing make-up class. Thus we need to investigate the following: 1. An understanding of mathematics for underachieved students. 2. A research of the learning contents that the students have difficulties to deal with. For this study we first select 20 underachieved students(12 boys and 8 girls) in mathematics attending an elementary school located in Busan and then a questionnaire is distributed to see their understanding of mathematics. In addition, their performances are evaluated by using a checklist. The questionnaire contains total 30 items and each frequency and percentage are analyzed. The checklist contains 10 items of the contents of 4-Ga and 4-Na respectively. textbooks, The frequency and percentage are also analyzed. We have the following conclusion on mathematics underachievers. First, since they have a negative opinion of the subject, we need to increase the chances of their successful experiences so that they have their confidence and positive attitudes. Second, we should try to teach basic learning contents at the beginning of each unit thoroughly and focus on advanced learning contents gradually by intensifying and reinforcing the contents. Third, it is more desirable to give them suitable assignments they can handle rather than to force to teach advanced contents. An evaluation should be given every time after finishing a unit, and the results should be informed to students. And make-up class should be given if necessary.

金甲洙,申判湜 嶺南大學校 工業技術硏究所 1996 工業技術硏究所論文集 Vol.24 No.1

The purpose of this study is to understand traffic characteristics of weaving sections. Therefore, this study has analyzed the characteristics of traffic flow on weaving sections on SHIN-CHUN in Tae-gu. Using the existing methods to analyze weaving sections, grasp the traffic characteristics of weaving sections, and then made a comparison and analysis between observed data and assumed data. Measuring effect on weaving sections in Highway Capacity Manual is average running speed of volumes running within weaving sections. Therefore, analyzing the variables effecting for running speed, volumes per lane, VR, and the length of weaving sections influenced running speed, but R did few influence running speed. And what influenced the traffic capacity of weaving sections is R and the number of lane rather than the length of weaving sections. It is estimated that average running speed which determine the LOS for weaving sections is almost 'C' or 'D' by observation and assumption and that the assumption between weaving speed and non-weaving speed by the methods of KHCM and HCM is very accurate with observation.

대부분의 대도시에서 있는 도시고속도로의 가장 중요한 기능은 이동성이다. 그러나, 대구광역시 도심에 위치한 신천고속화도로의 교통흐름은 주변 간선도로의 교통과 불완전 입체교차형태로 이루어져 있어, 그 처리 방식에 따라 병목현상을 초래하고 있다. 본 연구는 신천고속화도로와 접속되는 접속교차로의 운용방법을 각각의 대안으로 나누어 분석하였다. 대안 설정은 접속 교차로에서의 좌회전 현시 유무에 의해서 좌회전 없음 (대안 Ⅰ), 신천대로 상에 좌회전 (대안 Ⅱ), 대동로 상에 좌회전 (대안 Ⅲ)으로 나누었다. 분석은 각 대안별로 신천대로 Weaving 구간에서의 주행속도 변화, 인접교차로의 U-Turn 구간 V/C비 변화, 접속교차로의 평균정지지체시간 변화, 차량의 주행비용변화에 초점을 두고 실시하였다. 분석결과 대안 Ⅲ이 가장 좋은 효과가 있는 것으로 나타났다. The most important function of the urban expressway is a mobility in most cities. However, traffic flows of Sin-Chun Urban Expressway in Tae-gu is deeply affected by its intersection-type and traffic situation of crossing arterial roads. For instance, bottleneck in Sin-Chun Urban Expressway is affected by these two reasons. This study analyzed the effectiveness of the operational methods of intersection divided into three alternatives on the Sin-Chun Urban Expressway. The alternatives are made upon the existence of left-turn phase : left-turn prohibition by the existence and the non-existence of left-turn phase on cross street (Ⅰ), left-turn on Sin-Chun Dae-Ro (Ⅱ), and left-turn on Dae-Dong arterial road (Ⅲ), respectively. Each alternatives was analyzed according to the change of Running Speed in weaving area, the change of V/C ratio in U-Turn area, the change of Average Stopped-Time Delay in cross street and the change of vehicle operating cost. The results of the analyses showed that the third alternative was most efficient than the other alternatives.

This paper is about doing, understanding, and teaching mathematical problem solving. The goal of this study is to explain what goes in students'heads as they face with mathematical tasks of some complexity. First we describe the outlines of two major Categories which are central parts of theoretical framework for examining mathematical behaviors. And then we go in detail. the one is the Resources, which is the storage of mathematical knowledges possessed by the individual : what he knows, How he can use it. The other is the Heuristics, which is in general the strategies and techeniques for making progress on difficult problems as thumb rules of successful problem solving examined by G.Po´lya. Here we explore the nature of such strategies and the kinds of the knowledges which are in fact necessary for strategy performance.
