In order to attain the best-educated people in a rapidly changing, modern society with English is an official language, this study applies the problem-based learning (PBL) method to the English Science Class. PBL problems were developed for PBL classes, and their effectiveness has been proven. The focus of this study was five PBL questions posed during the first semester, targeting seven learners in the fourth grade of Elementary School A. The questions were divided into levels aimed at each grade, with the emphasis on specialized English education. Learners wrote journals, peer evaluations, and self-evaluations after finishing their PBL classes. Also, a survey about PBL was conducted after the first semester. The results of the study showed that learners experienced an 86% improvement in presentation skills, an 86% improved interest in learning, 86% better understanding, and 100% improvement in both problem-solving skills and cooperation. On the other hand, learners had difficulty in understanding PBL problems, and with research using the internet. PBL was somewhat unfamiliar to the students, but the survey found that learners are already aware of its effectiveness, and that they are interested in PBL.

The purpose of this study is to investigate the difference of learners' preference for animation movies in EFL English classes. In this study, four classes of 124 college students that participated in the English screen class employed an animation, Alice in Wonderland. This study examined the different activities of three categories of pre-study, while-study, and post-study. First, on the analysis of studying activities of 15 items, the results showed meaningful differences depending on the students' gender. That is, female students were more interested in mostly all of the activities, while male students' interests were skewed to some post-study activities. Second, comparing the differences of studying interest among the three groups, the low group is more concerned with the pre-study activities, while the higher group is generally interested in the while studying and post-study activities. Third, on the analysis of correlation between the three level groups and activities, the results indicated meaningful differences in some activities. In summary, based on the results of this research, it is necessary to consider the learners' variables and focus on the learners in the English screen class. Further, teachers should apply these results to the management of their screen class and to the development of teaching materials.

It has been widely researched in many studies what is the most effective way to learn English as a second language. It has been generally accepted that the most effective teaching method is to make students interested in learning of English. Teaching method has to be modified with the change of the times according to the demand of the students. The purpose of this study is to reveal that language teaming method through internet could be more effective than that of the existing teaching one by offline loaming. For this purpose some subject students were divided by two groups of the experimental and of the controlled. From the result of the study it could be derived that teaching method, by means of cyber lecture, make a great effect not only on the attitude but on the achievement of the students when they are in the class of English as a second language. This paper also shows what could be the typical model for the teaching method by internet based on the experiment. This kind of way of teaching is supported by the questionnaire which has much more positive response from the students who were in the member of experimental group. Finally such a experiment would be described based on the Web-oriented teaching method with the respect of education of digital contents.

기계부품의 소형화 , 고속화, 그리고 저공해, 저소음이 요구되는 세계적인 추세에서 정밀가공기술은 기계 및 전자산 업에서 중요한 위치를 차지하게 되었다. 특히, 무심연삭공정(Centerless Grinding)은 높은 생산성과 정확한 치수 형성의 능력이 있어서 원통형상을 가공하는 중요한 생산공정으로 사용되어 왔다. 예컨대 VCR의 소형 축. Computer Disk Drive, 초소형 모터, 연료분사기등은 쎈터레스 연삭공정을 통하여 높은 정밀도를 얻고 있다. 하지만 이 공정의 특수성과 측정의 어려움으로 인하여 이러한 정밀형상의 형성과정은 아직도 잘 밝혀져있지 않다. 무심연연삭 공정에서는 부품이 기계에 고정되어 있지 않고 공작물 받침날 위에 올려져 있으며 조절바퀴와 연삭바퀴 사이에 눌려져 있다. 조절바퀴가 마찰력으로 공작물을 돌려주며 연삭바퀴에서 연삭가공이 일어나게 된다. 조절바퀴와 연삭바퀴사이의 거리는 기계 자체의 탄성변형으로 인하여 항시 변화하게 되며 이 거리의 변화가 공작물의 정밀형상 형성에 결정적인 영향을 미치게 된다. 본 연구에서는 무심연삭공정중 공작물과 받침날, 조절바퀴, 연삭바퀴의 상대운동을 기하학적으로 해석하였다. 특히 간섭조건을 사용하여 실제 공작물의 운동을 해석하여 순간 명목 절삭깊이를 구하였다. 또한 연삭 특성실험식을 이용하여 수직 연삭력을 구하고 연삭기의 탄성변형을 구하여 순간 실제 절삭깊이를 계산하였다. 그로부터 진원도형성에 관한 기본식을 유도하였다. 본 연구에서 유도된 진원도 형성 식을 이용하여 실험과 동일한 조건으로 컴퓨터 시뮬레이션을 수행하였다. 그리고 원형중의 어떤 이상형상, 즉, 홈또는 돌기는 반복되어서 다른 돌기 또는 홈을 형성 하게되며 그 반복주기는 공작물이 조절바퀴와 연삭바퀴위에 떠있는 각도에 따라 결점 됨을 확인하였다.'유창성' 에 그 목표를 두고 있는 점을 감안한다면, 시작단계부터 반드시 정확한 발음을 지녀야 하는 가의 문제도 생각해 볼 필요가 있다. 경우에 따라서는, 정확한 발음은 그 언어에 대한 숙련도가 점차 높아짐에 따라 이와 병행하여 이루어지는 경우도 흔히 경험하는 일이기 때문이다. 결국 초등영어 교육과정에도 명시되어 있듯이 '...영어에 대한 친숙함과 자신감을 심어주고, 영어에 대한 흥미와 관심을 지속적으로 유지시키는 것이 중요하기' 때문에 무엇보다 중요한 측면은 흥미와 관심을 유지시키는 지적인 학습활동보다는 정의적인 학습활동의 전개가 필요하다고 하겠다. 유리된 AA의 세포독설과 관련된 세포내의 역할에 대해 의문이 제기되었다., PCL에 SOD-1도 경미하게 나타났으나, 경련이 나타난 쥐에서는 KA만을 투여한 흰쥐와 구별되지 않았다. 이상의 APT의 항산화 효과는 KA로 인한 뇌세포 변성 개선에 중요한 인자로 작용할 것으로 사료되나, 보다 명확한 APT의 기전을 검색하고 직접 임상에 응응하기 위하여는 보다 다양한 실험 조건이 보완되어야 찰 것으로 생각된다. 항우울약들의 항혈소판작용은 PKC-기질인 41-43 kD와 20 kD의 인산화를 억제함에 기인되는 것으로 사료된다.다. 것으로 사료된다.다.바와 같이 MCl에서 작은 Dv 값을 갖는데, 이것은 CdCl$_{4}$$^{2-}$ 착이온을 형성하거나 ZnCl$_{4}$$^{2-}$ , ZnCl$_{3}$$^{-}$같은 이온과 MgCl$^{+}$, MgCl$_{2}$같은 이온종을 형성하기 때문인것 같다. 한편 어떠한 용리액에서던지 NH$_{4}$

This study investigated the current state of writing in research papers of science education with focus on the translationese and basic Korean grammar, and found a way of improving the Korean language. The science education research have characteristics of both social science and natural science, and of having more quantitative than qualitative research, which could influence the writing of the research paper. The translationese means the conventional expression originated from foreign language other than Korean. The basic Korean grammar includes 'agreement,' 'spelling, word spacing, punctuation mark,' 'causative suffix,' 'use of English or loanword,' and the translationese is divided in 'English,' 'Japanese,' and 'English and Japanese.' The sentences in nine research papers in the 'Journal of the Korean Association for Science Education' were analyzed, and the problematic sentences were discussed and provided with alternatives. The cases with high frequency include '-jeok,' 'use of English,' 'expression of the plural,' 'passive voice of the verb with -hada,' '-go inneun,' '-eul tonghayeo,' '-e daehayeo,' 'gajida,' 'genitive case marker -eui,' 'passive voice with subject of thing,' and 'causative suffix, -sikida.' Based on the results, the characteristics of writing of science education research papers were described as 'writing of quantitative research,' 'objective writing of academic research,' and 'writing of research of foreign origin.' In order to improve the writing of research paper of science education, the science education researcher should pay attention to basic Korean grammar and the translationese, and be familiar with the concrete examples of problematic cases. The results of this study could be used in the education of writing and grammar of Korean language.

Most of the statistical packages being used in Korea, such as SAS or SPSS, are imported from foreign countries. Since these package are written in English, it is not easy for Korean to learn the statistical packages. Also, most of the users except statistician use these expensive packages only to draw pictures and to make tables. We introduce a Korean statistical package which can be used easily for general public.
