An important topic in current mathematics education research is to relate mathematics to communication. Communication in mathematics has been highlighted as an important goal for all children. And because writing is a way of clarifying and refining one's own thoughts, written communication is important. The purpose of this study is to examine the effects of mathematical writing activities on the achievement of elementary children in mathematics and on affective domain. That is, this study focuses on investigating the effects of mathematical writing activities on ability in and on attitudes towards mathematics. This study was designed to use nonequivalent control group pretest -posttest design. Two 6th grade classes were selected from an elementary school in Chinhae for this study, one for an experimental group and the other for a control group. One class was taught mathematics by using methods of writing activities and the other was taught by traditional methods. Students of experimental group were given worksheets for cultivating mathematics learning abilities in every session. These worksheets include completion, lead sentences, warm-ups, rewording, word banks and debriefing. And they were given worksheets for improving in mathematical attitudes one or two times in a week. They were asked to express feelings about mathematical story, to solve a mathematical puzzle, to draw a figure and to write about a given subject. This study was lasted from May 29, 2000 to July 15, 2000 for 7 weeks. The results obtained from the data analysis were as follows : 1.There was a significant difference between the experimental group and the control group in mathematics learning ability at the significant level of .01. 2.There was a significant difference between the experimental group and the control group in mathematical attitudes at the significant level of .05. That is, this research shows that writing activities in mathematics affect positively on mathematical attitudes such as learning attitudes of mathematics, the appreciation of usefulness about mathematics and the degree of interest in mathematics. The mean score of confidence on mathematics in an experimental group increased, but it is not significant. The results are like theses. An experimental group which has clone mathematical writing activities showed better mathematics teaming abilities and mathematical attitudes in affection domain than a control group which has not. The fact, tells us that mathematical writing activities make children to enhance the mathematical power and are effective to build up children's attitudes towards mathematics.

황인영,박정규,이은경 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.1

A common used endpoint in bioassays testing the estrogenicity of chemicals including endocrine disruptors is the induction of egg yolk precursor vitellogenin in male fish. Two marine fishes (Sebastes schlegeli and Paralichthys olivaceus) were exposed to the 17β-estradiol (E2) to determine the vitellogenin production. Vitellogenin was measured in fish blood using SDS-PAGE and Densimetry. Results showed that exposure to E2 caused vitellogenin in male fish. Especially, vitellogenin levels in young fish were about 4 times higher than in adult fish, which means young fish are more sensitive to E2 exposure. And plasma vitellogenin in fish increased related to E2 concentration and exposure duration.

제2형의 근관형태를 갖는 치아에서 각각의 근관을 모두 근관장까지 확대한 경우,여러 확대기구에 따른 최종근관장파일의 크기를 상호 비교하여 얼마나 많은 변화가 있었는지를 분석하고자 치근 우식이 없고 치근단공 형성이 완료되었으며 2개의 근관 입구에서 시작하여 하나의 치근단공을 갖는 제 2형의 근관형태를 보이는 상악 소구치,상악 대구치의 근심협측 치근 및 하악 대구치의 근심 치근을 선택하여 확대기구에 따라 KF 군, PT 군,HS 군, K3 군으로 분류하고 치경부 조기 확대를 시행하였다. 초기근관장파일이 15번 크기인 지아를 각 군당 20개씩 무작위로 선택하였고,모든 근관을 각 군에 해당되는 30번 크기의 파일까지 제조회사의 지시에 따라 확대를 시행한 후,촉감과 universal testing machine을 이용하여 최종근관장파일의 크기를 결정하였다. 각 군의 최종근관장파일의 크기와 제거 시 요구되는 힘의 크기에 대한 유의성 검증은 one-way ANOVA를 이용하여 비교 분석하였으며,사후검정은 Tukey HSD test를 이용하여 0.05의 유의수준에서 분석하였다. 본 연구의 결과 제2형의 근관형태를 갖는 치아의 근관확대 시,모든 근관을 각각의 근관장으로 확대하는 방법은 확대에 마지막으로 이용된 기구의 크기보다 한,두 단계 정도 증가된 최종근관장파일을 나타냈다. 그러므로 제2형 근관형태를 나타내는 치아의 근관치료 시 임상가들은 근관충전에 앞서 치근단 받침을 다시 확인하고 형성하는 과정이 필요하리라 사료된다. Type II root canal was defined that two canals leave the chamber and merge to form a single canal at short of the apex. The aim of this study was to analyse the master apical file (MAF) size according to various instrumentation techniques in the type II root canal when each canal was enlarged to working length. Eighty mesial roots of molar with ISO #15 initial apical file (IAF) size in type II root canals were randomly divided into four experimental groups with 20 teeth each. According to enlarging instruments, four groups are: K-FLEXOFILE^(?) (KF), engine-driven Ni-Ti PRoT_(APER)^(?)(PT), HERO Shaper^(?)(HS), K³™ (K3). All canals were enlarged to each working length with ISO #30 size: #30 in KF, F3 in PT, .04/30 in HS, and .06/30 in K3. The master apical file (MAF) size was confirmed by tactile sensation and universal testing machine (EZ test, Shimadzu Co., Kyoto, Japan). The mean MAF size was statistically compared using one-way ANOVA and Tukey HSD test at the 0.05 probability level. These results show that the MAF size was appeared one or two sizes larger than the final enlarging instrument when all canal in type II configuration were enlarged to each working length. Therefore, the clinician have to confirm the apical stop once more after instrumentation of type II root canal.

본고는 일제 강점기 조사 미등록 유물 정리사업의 일환으로 수행한 평양 남정리 53호분 출토 토제칠이배, 토제칠반, 토제칠안에 관한 연구이다. 남정리 출토 유물은 소지가 목심이 아닌 토제라는 것과 칠이배와 칠반을 얹은 칠안이 함께 출토되었다는 점에서 주목할 만하다. 토제칠이배 및 칠반 그리고 칠안의 보존처리를 통해 이들의 형태와 문양 등에 대해 알 수 있었다. 또한 칠기에 사용된 붉은색 안료의 성분을 분석하여 안료의 주성분이 진사(HgS)였음을 확인하였다. 이번 연구에서 기존에 잘 알려지지 않았던 한반도 내 위치한 낙랑의 토제칠기에 관해 살펴볼 수 있었으며 이러한 제작방법이 한나라 고유의 문화인지 아니면 재지세력이 한나라의 영향을 받아 현지화한 문화의 산물인지에 대해 생각해 볼 수 있는 기회라 생각된다. This research paper examines the lacquered pottery cup, plate and table unearthed from Tomb No. 53 at Namjeong-ri in Pyongyang, which were under conservation treatment as a part of the Project of Unregistered Artefacts Uncovered in the Japanese Colonial Era. It is very rare to have a lacquered pottery cup and plate, lying on a lacquered pottery table, as a set of grave goods. In particular, they are not wooden but pottery items. Through conservation treatment for lacquered pottery cup, plate and table, it was possible to find out their shapes and decoration patterns. The resulting analysis of the red pigment used indicates that cinnabar (HgS) is the main element. This research is significant because it examines lacquered pottery wares produced in Lelang, which has rarely been conducted. Further research will need to prove whether their production techniques were in the unique Chinese Han style or were produced by indigenous craftsmen who adopted the Chinese Han technique.
