This paper aims at investigating the structure and meaning of Sejangga, one of the six pieces of Gasa written by Lee, Un-yeong in the 18th century of the Joseon Dynasty. I thought that the existing studies had many problems in the interpretation of the meaning of Sejangga. So I reexamined the structure and meaning of Sejangga in relation to the folk song. Sejangga was written under the influence of the folk song to emphasize the intimacy of I and You with excluding others. In Sejangga the poetical narrator suggests that he and his grandson should harden intimacy with excluding grandson's maternal grandfather, because grandson's maternal grandfather released him from the magistrate of a country. But the hatred for grandson's maternal grandfather in the superficial narrative is denied by the interior meanings. And he and his grandson's maternal grandfather are shaped into the stupid persons by the humorous attitude of narrative. Accordingly it is obvious that the poetical narrator of Sejangga represents the affection for his grandson on the basis of the intimacy of he and his grandson's maternal grandfather. I anticipate that this study can contribute to ascertain the natures of Lee, Un-yeong's works and the aspects of Gasa in 18th century of Joseon Dynasty.

Thin films of vanadium oxide(VO_(x)) have been deposited by RF magnetron sputtering from V₂O_(5) target in gas mixture of argon and oxygen. The oxygen/(oxygen+argon) partial pressure ratio of 0% and 8% is adopted. Crystal structure and optical properties of films sputter-deposited under different oxygen gas pressures and in situ annealed in vacuum at 400℃ for 1h and 4h are characterized through XRD, XPS, RBS, FTIR, and optical absorption measurements. The films as-deposited are amorphous, but 0%O₂ films annealed for time longer than 4h and 8%O₂ films annealed for time longer than 1h are polycrystalline. I-v characteristics were distinguished between linear and nonlinear region. In the low field region the conduction is due to Schottky emission, while at high fields it changes to Fowler-Nordheim tunneling type conduction. The conductivity measurements have shown an Arrhenius dependence of the conductivity on the temperature.

In this study, quantity and quality of collected rainwater by sand, gravel, soil, lawn and concrete surface, as collection materials were investigated and Rainwater Collection Prediction Model was developed to predict the amount of collected rainwater. The quantity of collected rainwater in concrete surface, gravel, sand, soil and lawn collection system was 1,067L(93.2%), 1,006L(87.8%), 902L(78.8%), 800L(69.9%), 788.5L(68.8%) for 8 months period, respectively. The average turbidity of collected rainwater in concrete surface, gravel, sand, soil and lawn collection system was 3.2NTU, 2.2NTU, 1.9NTU, 1.7NTU, 1.5NTU for 8 months period, respectively. For sand collection material, predicted amount by the Model and actual collected amount were 931.5L and 902L, which were very closed. For gravel collection material, predicted amount by Model and actual collected amount were 1,028.21. and 1,006L, which were very closed. To simulate the optimal rainwater storage volume, the rainfall and evaporation data in Dae-jeon city were used. For sand collection system with 30m2 area, the maximum storage volume was 17㎥ and 62% of the year was secured for use of 240L/day.

It is important to study the activity of drug biotransformation enzymes, because from a pharmacological and therapeutic point of view these enzymes are resposible for eliminating most drugs. Their level is ciritical when deciding the dose regimen. (From a toxicological perspective, the role of these enzymes varies, with some of them being directly responsible for activation of certain chemicals to reactive intermediates with deleterious consequence to the animal.) Experiments were designed to measure in vitro, the activity of drug metabolizing enzymes in liver of Korean native cattle. The microsomal monooxygenase activities were evaluated utilizing specific substrates. The activities of BPDM and TST 6β-hydroxylase were seemed to be high level relatively to other monooxygenzses such as ECOD, EROD and AH. Interestingly, TST 16α-hydroxylase which is a maker enzyme for CYP ⅠLA was not detected in Korean native cattle. These results sugest that Korean native cattle have high contents of CYP IIB1 and CYP IIIA.

초기 톨루엔 농도가 톨루엔-NOx-공기 혼합물의 광산화 반응에 미치는 영향 : I. 가스상 물질의 변화 I. Change of Gaseous Species

An experimental investigation of the gas-phase photooxidation of toluene-NO_(x)-air mixtures at sub-ppm concentrations has been carried out in a 6.9 ㎥, indoor smog chamber irradiated by blacklights. Measured parameters in the toluene-NOx experiments included O₃, NO, NO₂, NO_(x), CO, SO₂, toluene, and air temperature. The initial toluene concentration ranged from 225 ppb to 991 ppb and the initial concentration ratio of toluene/NOx in ppbC/ppb was in the range of 5~20. It was found that the variation of gaseous species with irradiation time caused by the photooxidation of toluene-NOx-air mixtures depended on the initial toluene concentration for similar concentration ratio of toluene/NOx. The dependency of initial toluene concentration on the photooxidation of toluene-NO_(x)-air mixtures for toluene/NOx =5~6 seemed to be opposite to that for toluene/NOx=10~11. The arriving time at maximum ozone concentration depended on both initial toluene concentration and initial concentration ratio of toluene/NOx. However, the maximum concentration of ozone formed by photooxidation depended only on the initial toluene concentration.

An experimental investigation of the gas-phase photooxidation of toluene-NOx-air mixtures at sub-ppm concentrations has been carried out in a 6.9 ㎡, indoor smog chamber irradiated by blacklights. Measured parameters in the toluene-NO_(x) experiments included aerosol, O₃, NO, NO₂, NO_(x), CO, SO₂, toluene, and air temperature. The initial toluene concentration ranged from 225 ppb to 991 ppb and the initial concentration ratio of toluene/NOx in ppbC/ppb was in the range of 5~20. It was found that the variation of aerosol number concentration with irradiation time caused by the photooxidation of toluene-NOx-air mixtures depended on the initial toluene concentration for similar concentration ratio of toluene/NO_(x). The dependency of initial toluene concentration on the photooxidation of toluene-NO_(x)-air mixtures for toluene/NOx=5~6 seemed to be opposite to that for toluene/NO_(x)= 10~11. The maximum number concentration of aerosols formed by photooxidation and the aerosol yield depended on both initial toluene concentration and initial concentration ratio of toluene/NO_(x). In this study, the aerosol yield, defined as aerosol formed per unit toluene consumed, was found to be 0.01~0.16.

Air pollutants were measured eight times from June 1999 to June 2002 on regular ferries cruising across the Yellow Sea between Incheon in Korea and Qingdao or Tianjin in China. PM_(10) and PM_(2.5_ were measured as particulate matters and SO₂, CO, and NOx were measured as gaseous pollutants. On each route, sampling was made, starting two hour after departure and ending two hour before arrival. Low concentrations of gaseous pollutants that were not much varied according to sampling period and location revealed that atmosphere over the sea was not directly affected by anthropogenic emissions. However, concentrations of fine particles were generally higher than those measured at Deokjeok Island. 50 km west of the western seashore, at similar periods. It was believed that considerable influence of China in the form of secondary pollutants was exerted over the sea.
