본 원고는 2004년 과학사학자 박성래 교수가 독립 운동가이자 한국 근대 수학교육의 아버지로 부르기 시작한 보재 이상설(李相卨, 1870-1917)이 자연과학에 기여한 내용을 다루고 있다. 한국수학사학회지 2009년 11월 호에 자세히 소개된 〈數理〉를 쓴 시기를 전후하여, 같은 시기에 이상설이 붓으로 쓴 것으로 여겨지는 〈植物學>(이상설, 1899)은 총 4면의 초록 필사본이며, 그 대본(臺本)은 〈植物學啓蒙〉 (Edkins, 1886)으로 영국의 Joseph Edkins(艾約瑟, 1823-1905)가 번역하여 1886년에 간행한 〈西學啓蒙〉 16종 가운데 하나이다. 이상설의 〈植物學>은 이 〈植物學啓蒙〉을 읽으면서 그 책의 내용 중 당시의 조 선 학자가 모르고 있던 새로운 내용을 중심으로 메모를 한 것으로 여겨진다. 본 연구에서는 전통산학과 근대서양수학을 연결하는 〈數理〉를 저술했으며. 우리나라의 정규 교과과정에 수학과 과학을 필수과목으로 지정하고, 첫 번째 수학교과서 〈산術新書〉를 발간함으로 당대 최고의 수학자로 평가된 이상설이 쓴 〈植物學〉을 발굴하여 그 내용과 의미를 최초로 분석한다, 이를 통하여 당시 조선의 서양 과학, 특히 식물학에 대한 이해 수준을 분석하고 〈植物學〉의 원전인 〈植物學啓蒙〉 과 <西學啓蒙〉의 저자에 대하여 알아본다. 이는 당시 수학교육자가 자연과학분야에 행한 교육적 기여를 이해 하는데 필수적인 연구이다. This paper deals with contents that Sang-Seol Lee contributed to the natural science in the 19th century Korea. Prof. Sung-Rae Park, the science historian, called Sang-Seol Lee Father of the Modern Mathematics education of Korea. Sang-Seol Lee wrote a manuscript Botany with a brush in late 19th century. Botany was transcribed from Science Primers: Botany (written by J. D. Hooker), which is translated into Chinese by Joseph Edkins in 1886. The existence of Sang-Seol Lee`s book Botany was not known to Korean scientists before. In this paper, we study the contents of Botany and its original text. Also we analyze people`s level of understanding Western sciences, especially botany at that time. In addition, we study authors of 16 Primers for Western Knowledge. We study the contribution of mathematician Sang-Seol Lee to science education in the 19th century Korea.

수처리 부산물로 생성되는 염소산화물의 효율적 제거에 관한 연구

성대동,이성식 동아대학교 환경문제연구소 1999 硏究報告 Vol.22 No.1

The photodegradation efficiency of chlorine oxides in the drinking water has been studied by means of laser flash photolysis. The results are summarized as follows ; A high amount of ClO is produced just at the irradiation of laser flash. The absorption spectrum of ClO shows strong on the spectrophotometric measurement. The efficiency of removal of ClxOy reveals about 60~70% within 2㎲ after laser flash irradiation. The removal efficiency is decreased with the increase of the water thickness from 40㎝ to 80㎝ and also the efficiency is decreased about 4~6%. The removal rate of Cl₂O_(7) shows 3 times higher than one of Cl₂O_(6).

The effect of ozone on the formation and the removal of disinfection byproducts(DBPs) of chlorination process was studied to elucidate the performance of water treatment process. The samples of raw water, prechlorination process, and preozonation process were analyzed quantitatively according to the Standard Methods for the Examination of drinking water. As a result, most of total trihalomethanes(THMs) which were formed in prechlorine treatment process was not removed in the preozonation process. Most of haloacetic acids(HAAs), haloacetonitriles(HANs), and chloral hydrate(CH) was removed in sedimentation and biological activated carbon(BAC) filtration processes. However, DBPs were increased more or less by postchlorine step. In particular, the formation of THMs and HAAs depends on ozone more than chlorine, but, the formation of HANs and CH depends on chlorine more than ozone. The seasonal variation of DBPs concentration for the year needs to be investigated to study the temperature effect because DBPs strongly depend on temperature among various efficient factors.

Background : Spontaneous intracranial hypotension(SIH) is found as a not uncommon cause of headache recently. We wanted to study its demographic characteristics, presenting symptoms and findings and the effect of autologous epidural blood patch (AEBP). Methods : We retrospectively analyzed medical records of 11 patients who were diagnosed of spontaneous intracranial hypotension and treated with AEBP from March of 2006 to October of 2009. Results : Age of patients(10 female and 1 male) was ranged from 29 to 51 years (mean 38.8 years). Their presenting symptoms included typical postural headache(11/11), nausea and vomiting(7/11), dizziness(2/11), stiff neck or neck pain(2/11), shoulder pain(2/11), and back pain(1/11). In nine patients CSF pressure was checked, CSF pressure was less than 6 cmH2O in 8 patients. In nine of eleven patients, CSF leakage was detected in cisternography. Brain MRI showed diffuse meningeal enhancement in six patients and subdural hematoma in one. VAS of postural headache decreased from 8-10(mean 9.6) to 1-5(mean 1.6) after AEBP. Conclusion : Most of the SIH patients were otherwise healthy people. It was prevalent among women, especially young adult. AEBP showed as an excellent treatment modality.

골격성 Ⅲ 급 부정교합자의 악골 부조화가 구치부 치성보상에 미치는 영향

성지현,김성식,손우성 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.1

골격성 Ⅲ 급 부정교합자는 부적절한 악골 위치에서 기능 교합을 유지하기 위해 치아의 경사도와 수직적 위치가 변화하게 된다. 이러한 치성보상은 전치부 및 구치부 전반에 걸쳐 일어나며, 현재 보편적으로 시행되고 있는 악교정수술을 위한 술전교정시 이를 제거하여 각 골격 구조내에서 치아들이 적절히 위치되도록 하여야 한다. 전치부 치성보상에 관한 측모 두부방사선 사진을 이용한 연구는 많이 시행되어졌으나, 구치부 경사도에 관한 연구는 미미한 실정이다. 이에 본 연구는 성인 골격성 Ⅲ 급 부정교합자의 전후방적, 수직적 악골 부조화에 따른 폭경 부조화 및 구치 경사도 변화를 알아보기 위해 진단 모형상에서 상하악 견치, 제1소구치, 제1대구치 부위의 기저골 폭경을 측정하여 상악에 대한 하악의 비율을 구하였으며, 모형을 삭제하여 좌우 구치간 경사도를 측정하였다. 악골 부조화 심화에 따른 기저골 폭경 비율과 제1대구치 협설 경사도 변화의 상관관계를 조사하여 다음과 같은 결론을 얻었다. 1. 골격성 Ⅲ 급 부정교합자의 악공의 전후방적 부조화가 심화될수록 상하악 구치간 각도합이 증가하여 치성보상이 많이 일어났으며, 특히 하악 구치가 설측 경사되는 치성보상을 보였다(p<0.001). 2. 골격성 Ⅲ 급 부정교합자의 악골의 수직적 부조화 및 폭경 부조화와 구치부 치성부상 간에는 유의할만한 상관성이 없었다. 3. 골격성 Ⅲ 급 부정교합자의 전후방적, 수직적 부조화의 심화와 기저골 폭경 부조화는 유의할만한 상관성이 없었다. This study examined the relations between degree of posterior dental compensation and skeletal discrepancy in Class Ⅲ malocclusion. The pretreatment lateral cephalograms and dental casts of 87 skeletal Class Ⅲ adults were selected to provide a random sampling of skeletal Class Ⅲ malocclusion. Skeletal discrepancy was described with ANB angle, Wits appraisal, Sn-Mn plane angle, FMA and ratios of basal arch width. Degree of posterior dental compensation was described with macillary intermolar angle, mandibular intermolar angle and sum of intermoloar angle. The relationships between skeletal discrepancy and degree of posterior dental compensation were analyzed with simple correlation analysis, stepwise multiple regression analysis. The results were as follows : 1. A strong association was found between the variation in the anteroposterior measure, ANB angle and the variation of posterior dental compensation measures, sum of intermolar angle and mandibular angle and mandibular intermolar angle in skeletal Class Ⅲ malocclusion. 2. There was no statistically significant relationship between the variation in the vertical measures and the variation of posterior dental compensation measures in skeletal Class Ⅲ malocclusion. 3. There was no statistically significant relationship between the variation in the anteroposterior and vertical measures and degree of basal arch width discrepancy.

한국 근대수학교육의 아버지 이상설(李相卨)이 쓴 19세기 근대화학 강의록 『화학계몽초(化學啓蒙抄)』

Son, Yongkeun,Kim, Chae Sik,Lee, Sang-Gu,Lee, Jae Hwa 강원경기수학회 2012 한국수학논문집 Vol.20 No.4

본 원고는 한국 근대 수학교육의 아버지 이상설(李相卨, 1870-1917)이 자연과학-화학-에 기여한 내용을 다루고 있다. 이상설은 "수리(數理)"를 쓴 시기를 전후하여, 같은 시기에 붓으로 총 46쪽에 달하는 "화학계몽초(化學啓蒙抄)"를 필사하였다. 분석해 본 결과 그 원전은 영국인 H. E. Roscoe(羅斯科, 1833-1915)가 1876년 발간한 Science Primers: Chemistry를 영국인 선교사 Joseph Edkins(艾約瑟, 1823-1905)가 번역하여 1886년에 간행한 "화학계몽(化學啓蒙)"으로 "서학계몽(西學啓蒙)" 16종 가운데 하나이다. Sang-Seol LEE wrote a manuscript HwaHakGyeMongCho(化學啓蒙抄) in the late 19th century. HwaHakGyeMongCho was transcribed from Science Primers: Chemistry (written by H. E. Roscoe), which is translated into Chinese by Joseph Edkins in 1886. LEE did not copy original writing exactly, but he understood the contents of each chapter and sections, then summarized and edited them in his caligraphic writing. In this paper, we introduce the contents for the first time and discuss the significance of this book.

Physico-chemical characteristics of municipal solid waste(MSW) are very important factors for managing MSW. Also these factors are needed to estimate the type and the capacity of MSW treatment facilities. Actually the management of the MSW treatment facilities are often poorly accomplished because the evaluation of the MSW treatment facility have been carried out without considering the data-base for the characteristics on MSW. Hence, it is necessary to measure the characteristics of MSW for establishing the facilities with accurate data-bases about MSW. Analytical investigations were carried out to study physicochemical characteristics and heating values analysis of MSW generated from various sources in Chung-Ju city. Samples were collected at chung-ju city and were conducted for ultimate and proximate analysis. The physical compositions of combustibles of house were 89.7∼94.0% and non-combustibles of house were 6.0∼10.3%, the apparent densities were 204.7∼309.7 kg/㎥. Chemical compositions in houses were C 46.1∼46.7%, H 6.2∼6.4%, O 37.3∼37.7%, N 1.9∼2.0%, S 0.3∼0.4%, Cl 1.2∼1.4% and ash 6.1∼6.3%. Low heating value of the house in chung-ju city showed 1,879∼2,124 kcal/kg and high heating values were 4,504∼4,541kcal/kg.
