정신지체 환자에서 외래전신마취 하 치과치료 후 발생한 폐렴 -증례보고-
서광석,장주혜,신터전,이영은,김현정,Seo, Kwang-Suk,Chang, Ju-He,Shin, Teo-Jeon,Yi, Young-Eun,Kim, Hyun-Jeong 대한치과마취과학회 2008 Journal of Dental Anesthesia and Pain Medicine Vol.8 No.2
A 15-years-old female patient with seizure disorder and pervasive developmental disorder was scheduled for dental treatment under ambulatory general anesthesia. She had past history of pneumonia and herpes encephalitis when she was 3 year old. Because of sever mental retardation and behavior disorder, routine laboratory test was substituted with physical exam and medical records of department of pediatrics. A few days before general anesthesia, she showed slight common cold, but pediatric consult had reported that there was minimal risk in general anesthesia. After 4-hour general anesthesia, she became critically sick with high fever, cough and malaise. After 10-day hospitalization with pneumonia and sepsis, she could go home.

This paper is a research on the life cycle assessment (LCA) of plastic bag, bottle and container. In order to compare the environmental analysis of plastic, paper, pulp, aluminium, glass and steel material, it is studied by LCA technique from before-discarded step such as the material collection, processing of product, energy and water consumption, and product transportation, to after-discarded step such as waste product transportation, air and water pollutant discharge, waste generation, and treatment and/or disposal of waste. As a results, plastic material has a better environmental assessment than the other materials in before- and after-discarded step. So, plastic material must be newly concerned with a green material, and must be reappraised to the waste-deposit systems.

서광석 김천대학교 1989 김천대학교 논문집 Vol.10 No.-
The serea from of 191 coal workers' pneumoconiosis (CWP) patients, 65 healthy coal workers, and 52 no~mining controls were examined for antinuclearantibody (ANA) and rheumatoid factor(RF) accordingly age, year of exporse, opacity size, smoking and drinking habit. The result of analyses were as follow ; 1. Sera with ANA was shown 24. 3 %· of CWP patients, 10. 8 % of healthy coal workers (mining controls) , and 11. 5 % of non-mining controls. The proportion of sera with ANA were different among smoking habit groups and drinking habit group in CWP patients. (P<0.1) 2. RF and detected 36. 5 % of sera from the CWP patients, 13. 8 % of healthy coal workers, and 9. 6 % in non- mining controls. The proportion of sera with RF was increased with the age' group and opacity size 3. Proportion of the sera with either of ANA and RF were increased with age group, and opacity size, And there were difference of percentage the sera with ANA and/or RF accordingly the groups of smoking and drinking habit in CWP cases.
논문집 초록 : 학술발표일정 ; 3. 포스터발표 : Chlorella ellipsoidea의 이소프레노이드 조성에 미치는 pH의 영향

Chlorella ellipsoidea 세포에서 이소프레노이드(isoprenoid) 조성에 미치는 pH(4.0, 9.0)의 영향을 분석하였다. 세포의 생장과 이소프레노이드(isoprenoid)의 함량은 대조구(pH 7.4)에 비해 pH 4.0 배지에서 현저히 감소하였다. C. ellipsoidea 세포의 이소프레노이드 합성의 전구물질인 세스퀴테르펜(sesquiterpene, ST) 계열인 펜타데칸(pentadecane)과 디테르펜(diterepene) 계열인 피톨(phytol)의 생성율이 대조구에서 높았고, pH 4.0 배지 및 pH 9.0배지를 처리할 때 대조구에 비해 생성율이 50% 이상 억제되었다. The effects of pH on the compositions of fatty acids in Chlorella ellipsoidea were studied in the biosynthesis of isoprenoid. Growth and the contents of isoprenoid in pH 4.0 culture media were lower than those of the control. In C. ellipsoidea, pentadecane of the sesquiterpene family and phytol of the diterpene family were confirmed to be higher in isoprenoid biosynthesis of the control, while in treatment with pH(4.0, 9.0) were lower by over 50% compared with the control.
