接辭-ING形에 對한 歷史的 硏究 : 분사와 진행형을 중심으로
李範鎭 圓光大學校 1990 論文集 Vol.24 No.1
In this paper I explored the diachronic development of the affix '-ing' from Old English period. In OE the affix '-ing/-ung' was mainly used abstract nouns, byt Modern English the affix '-ing' has various functions:nouns, participles, gerunds, etc. This indicates that affix '-ing' has developed from the amalgamation of various old affixes '-ing/-ung', '-ende', '-end, and '-enne'. This amalgamation had been took place from Late Old english period to Middle English period. In various developments, the affix '-ing' is the combination of the auxiliary verb and the participle '-ende' which has been changed into '-inge'. Now we call this form 'progressive'. This form accounts, not only for the greatly increasing frequency of the construction, but for the much greater precision with which the expanded forms are used in modern times.

This study was conducted to evaluate the levels of exhaust emission of vehicles from Yesan Gun area. During 1995 through 1996, 360 vehicles were sampled randomly and analyzed by vehicle owner's characteristics, owner's vehicle manufacturing companies, owner's vehicle purchase types(new or used), owner's vehicle residence, owner's vehicle types, vehicle fuels used, vehicle mileages, and vehicle model years, also vehicle exhaust emissions on idling condition were measured. To evaluate the exhaust emissions of the diesel engine vehicles(n=140) by particulate, those of the gasoline engine vehicles (n=220) were examined by CO and HC. The results were as follows; 1. The frequency of vehicle owner's gender was 287 persons in male and 18 persons in female, whereas that of vehicle purchase types(new or used) was 306 persons in new vehicles and 53 person in used vehicles. The frequency of owner's vehicle residence was 214 persons in town area and 144 persons in rural area, whereas that of owner's vehicle manufacturing companies was 141 persons in A company vehicles, 141 person in B company, 42 persons in C company, and 35 persons in D company. 2. The mean value of vehicle model years was 3.2±2.9 years in gasoline engine vehicles and 3.1±1.8 years in diesel engine vehicles, whereas that of vehicle mileage was 5.6±4.3(10,000Km) in gasoline engine vehicles and 6.1±6.5(10,000Km) in diesel engine vehicles. But no significant difference in vehicle model years and vehicle mileages between the diesel engine vehicles and the gasoline engine vehicles was observed The mean value of vehicle exhaust emission of CO or HC was 0.70 ± 1.75 ppm (CO) and 93.29 ± 127.96 ppm (HC) in gasoline engine vehicles, respectively, whereas that of vehicle exhaust emission of particulate was 34.31 ± 12.02 in diesel engine vehicles. 3. In pearson's correlation analysis of gasoline engine vehicles, HC was correlated with CO(r=0.64, p=0.0001), vehicle mileage(r=0.25, p=0.0002), vehicle model year(r=0.23, p=0.0006), and remnant period of regular exhaust emission examination(r=0.09, p=0.1925). In pearson's correlation analysis of diesel engine vehicles, particulate was correlated with remnant period of regular exhaust emission examination(r=0.16, p=0.0599), vehicle model year(r=0.09, p=0.2745), and vehicle mileage(r=0.01, p=0.8297). 4. Multiple linear regression analysis using CO as dependent variable and selected variables(owner's gender, owner's age, vehicle manufacturing company, vehicle purchase type, remnant period of regular exhaust emission examination, vehicle mileage, and vehicle model year) as independent variables, revealed that none of them was significant to the dependent variable. Multiple linear regression analysis using HC as dependent variable and selected variables as independent variables, revealed that owner's gender was significant(p=0.012) to the dependent variable, and vehicle model year was marginally significant(p=0.063). Multiple linear regression analysis using particulate as dependent variable and selected variables as independent variables, revealed that vehicle model year was significant(p=0.015) to the dependent variable, and vehicle mileage was marginally significant(p=0.096). 5. Logistic analysis of the excess of exhaust emission criteria of CO with selected independent variables(owner's gender, owner's age, vehicle manufacturing company, vehicle purchase type, remnant period of regular exhaust emission examination, vehicle mileage, and vehicle model year) indicated that only vehicle model year was significant to the dependent variable(odds ration=1.233, 95% confidence interval : 1.094- 1.389). Logistic analysis of the excess of exhaust emission criteria of HC or particulate with selected independent variables indicated that none was significant to the dependent variable, respectively.

튜브형 이산화질소 passive sampler의 태양광 영향에 관한 분석
이범진,김학민,인치경,김선태 대전대학교 산업기술연구소 2000 산업기술연구소 論文集 Vol.11 No.2
The purpose of this study is to estimate the effect of sunlight on the measurement results of the tube type of NO2 passive sampler. Total 252 samples; seven duplicates, two sites with different concentration level, and nine days concerning to both exposure to sunlight and screened passive samplers with aluminium foil, were measured and analyzed. Relative standard deviation(%) of measurement data in this study was calculated as less than 10%, and it meant that even the simplest passive sampler showed comparatively high precision. The average concentration values of the screened passive samplers were turned out to be 22.4%∼25.5% higher than that of the passive samplers which were exposed to sunlight. Consequently, the sunlight was found to be the most important meteorological factor to affect the measurement for the tube type of passive samplers.
