LOGO 프로그램의 기하교육에의 도입과 활용방안

金姸美,李芝瑛 弘益大學校 科學技術硏究所 2000 科學技術硏究論文集 Vol.11 No.-

Mathematical visualization is a process to make mathematical images and use the image toward discovery and understanding. Hence, it is not proposed to make visual materials simply, but it has to have a circumstance that explores to visual object. In mathematics education, visualization has been ignored for a long time because people got used to manufacturing number or simbols. Therefore LOGO is a useful program that makes mathematical visualizaion possible for students. The purpose of this study is an application of LOGO program into geometry education through the mathematical visualization.

진정법을 이용한 치과치료 시 편도선의 크기가 행동에 미치는 영향

김현지,백광우,마연주,정영정 大韓小兒齒科學會 2010 大韓小兒齒科學會誌 Vol.37 No.3

본 연구에서는 진정법을 이용한 치과치료에서 소아환자의 편도선 크기가 진정법 중 환자의 행동에 미치는 영향을 평가하기 위해 진정법으로 치과치료를 받은 소아환자 35명의 진정기록지를 분석하였다. 진정법은 chloral hydrate 50 mg/kg, hydroxyzine 1 mg/kg를 경구투여하고, 치료 중 50% 아산화질소-산소 흡입 진정 및 필요에 따라 midazolam의 점막하투여(0~0.3 mg/kg)를 병행하는 방법으로 시행되었으며, 편도선의 크기는 Brodsky 분류법을 이용하여 4그룹으로 분류하였다. 환자의 진정 기록지를 분석하여 다음과 같은 결과를 얻었다. 1. 진정법 중 행동 반응은 수면, 움직임, 울음, 전반적 행동 모두에서 편도선 크기가 클수록 낮은 지수(negative behavior)를 보였다(p<0.05). 2. 편도선의 크기는 진정법 중 구호흡과 유의한 연관성을 보였으나(p<0.05), 진정법 중 코골이, 기침과는 유의한 연관성을 보이지 않았다(p>0.05). 3. 편도선의 크기가 큰 환자일수록 midazolam의 점막하투여량이 유의하게 증가하였다(p<0.05). The purpose of this study was to evaluate the effect of children's tonsil size on the behavior during pediatric dental sedation. The sedation records of thirty five children were examined in this study. All the sedations had been performed using chloral hydrate/hydroxyzine, nitrous oxide/oxygen or/and submucosal midazolam, and the subjects were divided into 4 groups according to their tonsil size using Brodsky's tonsil classification. The results were as follows: 1. The patients with enlarged tonsils showed negative behaviors in all behavior rating aspects(sleep, movement, crying, overall behavior) during sedation than those with normal tonsils(p<0.05). 2. Enlarged tonsils were correlated with mouth breathing(p<0.05) but not with snoring and coughing(p>0.05) during sedation. 3. For the patients with enlarged tonsils, significantly higher doses of midazolam were administered during sedation than for those with normal tonsils(p<0.05).

This study was designed as a non-equivalent control group pre-post-test quasi-experimental study. The subjects of this study were those who underwent operations under spinal anesthesia and the purpose of this study was if warming methods of pre-operatively applied would decrease the thermal discomfort. The Results of this study were as follows: Hypothesis #1-1 “The VAS anxiety of the experimental group who received warming methods during operation would be lower than that of the control group” was supported (t= -3.069, p= .004). Hypothesis #1-2 “The post-operative vital signs of the experimental group who received warming methods would be lower than that of the control group” was not supported(systolic blood pressure: t= -1.277, p= .208, diastolic blood pressure: t= -.785, p= .436, pulse: p= .861, t= .394). Hypothesis #2-1 “There would be difference in the level of body temperature of the experimental group who received warming methods during operation compared with the control group” was supported (F= 9.109, p= .004). Hypothesis #2-2 “The objective thermal discomfort of the experimental group who received warming methods during operation would be lower than the control group” was not supported (F= 1.001, p= .323). Hypothesis #2-3 “The subjective thermal discomfort of the experimental group who received warming methods during operation would be lower than the control group” was supported (F= 36.044, p= .000). In conclusion, the results of this study revealed that the warming methods implemented before and during operation helped to increase the cutaneous temperature and decrease thermal discomfort which could occur during operation under spinal anesthesia, proving to be effective nursing intervention.

We have compared and analyzed softwares for mathematics education in Korea and USA. The purpose of this research is to help parents and teachers with selection of softwares and to offer data and information to software designers and companies. Korean softwares are superior than American products in curriculum, American products were found to be superior in motivation and feedback.

해저형상에 따른 연안유속분포형상

This paper aims at the elucidation of the characteristics of longshore current profile after wave breaking. Wave breakers are always accompanied by complex turbulent process, wave energy losses and the mean water level variations due to the gradient of radiation stress. These processes with other factor result in the development of longshore currents. Because longshore current have relation to the alongshore sand transport on a bed and, to the diffusion of contaminants nearshore region, the understanding and elucidation of longshore currents are very important from tile engineering point of view. The longshore currents induced by simple wave striking an planar beach, nonplanar beach, and barred beach are calculated.

미생물응집제를 개발하기 위하여 자연계로부터 방선균 600여 균주와 보관균주를 대상으로 응집활성이 우수한 균주를 선별하고 동정한 결과 corynebacteium 속으로 동정되었다. 응집제 생산을 위한 최적조건은 2% glycerol, 0.4% peptone, 0.1% yeast extract, 0.3% K_2HPO_4, 0.1% CaCO_3, 0.05% NaCl, 0.1% MgSO_4·7H_2O, pH 7.5의 배지 100 ml을 500ml baffle flask에 넣고 96시간 회전진탕배양할 때였으며 상기의 조건으로 jar fermentor 배양시 96시간에서 780 units/ml의 응집활성을 나타내었다. 응집물질은 pronase 처리와 periodate 산화에 의해 각각 무처리구와 13%와 106%의 활성을 나타냄으로써 응집활성은 주로 단백질에 기이함을 알 수 있다. About 600 microorganisms isolated form soil, marsh, compost, etc. were examined for their flocculating ability in the kaolin suspension and swine wastewater. Among them, K-199 was the best producer of flocculant and was identified to be a species belong to the genus corynebacteium. The maximum production of the flocculant from Corynebacterium sp. K-199 was observed in culture medium containing 2% glycerol, 0.4% peptone, 0.3% K_2HPO_4, 0.1% CaCO_3, 0.05% NaCl, 0.1% yeast extract, 0.1% MgSO_4·7H_2O and initial pH 7.5 when cultured with rotary shaker controlled at 25℃ and 150 rpm. Under the optimal culture condition with jar fermentor, the maximum production was reached to flocculating activity of 780 units/ml after 4 days. From the results of the activity be fully maintained by periodate oxidization, it suggests that the activity is due to the protein.

한국과 미국의 초등학교 수학 교과서 및 교육과정의 비교와 분석

金姸美,李芝瑛 弘益大學校 科學技術硏究所 2001 科學技術硏究論文集 Vol.12 No.-

We have compared and analyzed mathematics curriculums for the elementary schools of Korea and USA. We have reviewed them and found some similarities and differences. We strongly believe that the 7th mathematics curriculum of Korea follows the curriculum suggested by NCTM in USA. Both of the curriculums emphasize "mathematical literacy", which means mathematical power. And they've also emphasized to use calculators and computers in a classroom to prepare the 21th century.

실측자료를 이용한 교각 세굴방정식의 비교

Over the past 30years, numerous studies have been conducted and equations developed to Predict bridge-pier scour. Most of these equations were developed using laboratory data and sometimes tested using limited field data. For a number of the equations, the conditions under which the laboratory experiments were conducted are unknown. In addition, the ranges of the various parameters over which the equations are valid are also typically unknown. Even if the range of data used in the laboratory study is known, it is quite uncertain as to flow those ranges, using small-scale models, correlate to prototype conditions. The purpose of this study is to compare seven bridge-pier-scour equations using field data. Data for live-bed scour will be examined; most floods the stream bed is live, there are cases. The limitaions of each of the equations will be examined for the purpose of providing guidance to hydraulic engineers concerned with scour at bridge piers.
