본 연구의 목적은 삼각함수에 관한 학생들의 오개념을 분석해보고 삼각함수 개념 지도 개선방안의 하나로 컴퓨터를 활용한 지도 방법을 고안하는 것이다. 이를 위해, 이미 삼각함수를 배운 학생들을 대상으로 삼각함수 개념과 관련된 학생들의 이해도 검사를 실시하여 호도법 활용과 삼각함수그래프와 관련된 학생들의 오개념을 분석하였다. 분석 결과를 바탕으로 GSP를 활용한 학생 주도형 교수-학습 자료를 고안하여, 삼각함수그래프 지도과정에 투입하였다. 그 결과, 컴퓨터 조작에 의한 역동적인 탐구과정이 학생들이 호도법과 삼각함수그래프를 이해하는데 도움을 줄 수 있음을 확인하였다.

Esophageal foreign bodies are common problems in the part of otolaryngology department, and may cause severe complications such as esophageal ulceration, esophageal perforation, periesophagitis, tracheoesophageal fisula, pneumothorax and pyothorax. Therefore, early diagnosis and intervention is needed to reduce morbidity and motality. But, calcification of the laryngeal cartilages may masquerade as foreign body in some patients with a history of foreign body ingestion. Recently, We experienced a case of calcification of thyroid cartilage which was misunderstood as an esophageal foreign body and report this case with a review of literatures.

This survey was conducted to provide fundamental data for a practical school health education by grasping the extent to what schoolgirls in Korea made out the conceptions for nutrition often misunderstood. Questionnaires were given to schoolgirls in the 3 classes per grade in a school in Seoul and in the 2 classes in a school in a rural area from the ist grade in the middle school to the 3rd grade in the high school; which were selected at random by school nurses. 96.6% of Questionnaires were collected(total 1,689) and by means of computational treatment of them the anther obtained statistically highly significant results. 1. on the average sghoolgirls had incorrect conceptions on 9.29 items (37.16%) of total 25 items which are often misunderstood. 2. Shoolgirls in higher grades revealed misconceptions on less items than those in lower ones : on 9.56 items in the case of those in the middle school and on 8.82 items in the case of those in the high school. 3. Three major misconceptians of total 25 ones were as follows; (1) Chemical additives are dangerous in food (86.7%). (2) Spinach is a highly concentrated source of vitamins and minerals (82.8% ), (3) The more vitamins you take the better (71.3%).

1. Objectives : The Crown Prince Sohyen(1612-1645) has been believed ro have been poisoned to death because of the political conflict with the King Injo. However, the Crown Prince Sohyen who was So-yangin(SY type) didn't be treated properly at that time. This paper is supposed to explain the reason why he died by reference. 2. Methods : The prescription which was made out to the Crown Prince Sohyen is analyzed, based on the Sasang Constitutional Medicine(SCM) through Shimyang-ilgy and Ulyudongkung-ilgy. 3. Results : 1) In the case of the prescription where So-yang medical stuffs were contained a lot or Gunyak(the main madical stuff) was So-yang one, the Crown Prince Sohyen was better, while that of Tae-eum and So-eum medical stuffs didn't work. Therefore, the Crown Prince Sohyen can be considered So-yangin. 2) The So-yang in's symptom was misunderstood as Hakjil and treated, which could lead him to be put to death 4. Conclusions : The Crown Prince Sohyen is supposed to be Soyang-in(SY type), and accordingly the So-yang in's symptom was misunderstood as Hakjil and treated, which could cause him to pass away.

본 연구는 연립방정식과 연립부등식에서 탈북학생들이 나타내는 오류의 유형과 수학적 담론의 특성을 파악하여 학습의 향상을 꾀하고자 시도되었다. 이 때 담론중심의 학습은 학생들을 수학적 언어의 공동체로 이끌어내는 수단이 되어 자신감을 극복할 수 있게 돕는다. 이를 위해 다양한 배경을 지닌 5명의 탈북학생을 대상으로 2011년 1학기 서울에 위치한 모OO 대안학교에서 보충수업일환으로 8차시 연구가 수행되었다. 학습과정은 녹음되어 전사되었고, 학생의 학습지, 연구자의 관찰지가 수집되었다. 연구결과로는 탈북학생들은 기술적 오류, 기록오류, 잘못 이해된 기호, 잘못 해석된 언어, 한자어 해석오류를 보였고, 담론은 제 0수준으로부터 서서히 상위수준으로 향상은 보였으나 최상의 수준인 제 2수준~3수준은 단편적으로만 나타났다. 그러나 담론의 요소인 설명하기와 정당화하기가 활성화되면서 상호작용의 ERE 패턴에서 Ev(평가)와 Eb(정교화)가 증가하는 긍정적인 양상을 보였다.

It is expected that the change of industrial structure of Knowledge based economy, and service based economy would affect on economic life of physically-challenged person with no exceptions. There have been some former studies which have been misunderstood the employment of disabled due to the declining employment of the disabled and prejudice to the disabled based on biased perspective and public opinion. This study have analyzed the employment conditions of the ordinary workers and disabled workers out of those prejudices and biased opinions. Wage, economic activity ratio, age, educational background and industry those 5 parameters are brought for analyzing the two comparison group. Each parameter have compared based on the statistical data of ordinary workers and disabled workers for past 7 years. Weight between each parameter have been drawn by collecting the experts' opinion using AHP(Analytic Hierarchy Process), and utility of employment of two comparison groups have been estimated through progress inclination of each parameter. Through the estimated outcome, present condition and controversial issues and way of improvement of domestic employment of ordinary workers and the disabled is mentioned.

초 중등학교 수학 용어의 대부분은 한자말이거나 한자말이 섞여 있다. 한자말 용어의 각 한자를 한자사전을 통해 확인하고, 한자의 뜻으로 한자말 용어를 이해할 수 있는지를 비판적으로 검토한다. 이를 통해 한자말이거나 한자말이 섞여 있는 수학 용어들을 한자의 뜻이 그것이 들어있는 용어의 개념을 이해하는 데 도움이 되는 경우와 도움이 안되는 경우 및 한자의 뜻이 오히려 잘못된 개념을 얻게 하는 경우로 나누어 파악한다.

Educators have found that the concept of randomness is often misunderstood by students. Chance recently pointed out that students should be introduced to the concept of randomness through the use of simulations. In this article, we studied various aspects of the probability distribution off linear random path in a circle and introduce some related simulations to guide student exploration and discovery. Consider a random line segment that crosses a circle with a certain radius. Perhaps it can be considered to be a path that an airplane shows up and flies into a random direction in a monitor. What is the expected amount of flying distance through the monitor, and the expected variation\ulcorner Are we monitoring what we see scientifically\ulcorner This article studies the probability distribution and some related aspects of a linear random path within a circular monitor. Some simulative activity is also introduced which can be used in a statistics or probability classes.

The glass of Ground Granulated Blast Furnace Slag(GGBFS) was released by the hydroxyl ions during the hydration of the Portland cement. That results in relatively less $Ca(OH)_{2}$ in the concrete replaced with GGBFS than in ordinary portland cement concrete(OPCC). As the quantity of $Ca(OH)_{2}$ is decreased, the rate of carbonation in the concrete replaced GGBFS is faster than OPCC. Therefore, it has been misunderstood that the concrete replaced GGBFS has negative effect on the corrosion of steel by carbonation. Therefore, this study aimed at the relation between carbonation and rebar corrsion in the concrete with GGBFS, measuring air.water permeability, half cell, and corrosion rate by the depth of carbonation.
