  • This study was conducted focusing on the stability on materials of cultural property when the fumigant containing ethylene oxide was applied among some kinds of fumigant. Four kinds of specimens from paper, textile, metal and pigment were prepared to compare color difference, weight, surface condition before and after treatment and FT-IR analysis was carried out on specimens of paper and textile. In the case of fumigation treatment, it was conducted by two groups : one is made up of specimens with the non-fumigation as control groups, the other is made up of specimens treated with ethylene oxide + $HFC_{134a}$ and ethylene oxide + $CO_2$ as experimental groups. The result of color difference showed that there were color differences on the specimens of Hanji(Korean traditional paper), silver, cotton, ramie and yellow pigment. Especially, it was found out there was color change more than 6.0 on average from the silver specimen. However, in the silver specimen's case, color change in the non-fumigated specimen was relatively higher than those of fumigant-treated specimens, therefore, it is judged that fumigant doesn't have a decisive effect on color change in specimens, but required caution while fumigating. The result of weight measurement, there were totally 0~2% weight changes and the slightest change was found in the metal specimen, the biggest change in the papers. The result of microscopic observation on the surface of specimens showed color changes and especially, the biggest change on the silver specimen was observed. But no change in components was identified from FT-IR analysis of papers and textiles.

  • Effects of elevated $CO_2$ on soil microorganisms are known to be mediated by various interactions with plants, for which such effects are relatively poorly documented. In this review, we summarize and syn­thesize results from studies assessing impacts of elevated $CO_2$ on soil ecosystems, focusing primarily on plants and a variety the of microbial processes. The processes considered include changes in microbial biomass of C and N, microbial number, respiration rates, organic matter decomposition, soil enzyme activities, microbial community composition, and functional groups of bacteria mediating trace gas emission such as methane and nitrous oxide. Elevated $CO_2$ in atmosphere may enhance certain micro­bial processes such as $CH_4$ emission from wetlands due to enhanced carbon supply from plants. How­ever, responses of extracellular enzyme activities and microbial community structure are still controversy, because interferences with other factors such as the types of plants, nutrient availabilitial in soil, soil types, analysis methods, and types of $CO_2$ fumigation systems are not fully understood.

  • Hunter's color value "a" in dried-persimmon of table and full ripe fruit was higher than that in unripe fruit. In case of soluble solid content, full ripe fruit was $50^{\circ}Brix$, the highest degree, while unripe fruit was $40^{\circ}Brix$, the lowest degree. PPO activation of unripe fruit was 4.7, which was higher than table-ripe fruit (0.7) and full ripe (1.0). Polyphenol oxidase activation remained even while drying, but there was no difference in PPO activation degree as drying period increased. Total phenol content of unripe fruit was 101.4, which was higher than table-ripe fruit (57.5) and full ripe fruit (67.4). Total phenol content level increased as drying period increased, which was based on fresh weight. Hardness of unripe and table ripe fruit continued to decrease until three weeks during softening. After that, hardness was high and it started drying. However, in full ripe fruit, hardness increased after two weeks and softening was fast during the drying period, and its weight reduction rate was lower than that of unripe and table ripe fruit.

  • Air pollution is directly and indirectly associated with the toxicology through the increase of mortality, the decrease of oviposition rate, and the decline of insect population, as well as the disruption of equilibria with higher or lower trophic levels. To investigate intrinsic decrease rates, oviposition period, and emerging rates of pupae of house fly under air pollution stresses, healthy individuals of Musca domestica L. were collected in the field, cultured in the laboratory for 2 $\sim$ 3 generations, and artificially exposed to $O_3 (4 ppm) in automatically controlled air pollutant fumigation chambers. Results from this study are summarized as follows: 1. Survivorship curves of both control group and exposed groups of healthy house fly to 4 ppm $O_3$ have linearly or stair-like decreasing trends of revers S-shape. 2. For cohorts exposed to 4 ppm of $O_3$, intrinsic decrease rate of cohort exposed for 2 hours significantly increases compared to that of control group, slight increases were observed for those exposed for 4 hours and 8 hours, which shows no distinct relationships between exposure period and intrinsic decrease rate. 3. While the numbers of pupae of exposed cohorts increase with the increase of exposure period, emerging rate shows a distinct decrease. 4. The relationships between emerging rate (E) of pupae and the exposure period (T) for cohorts exposed to 4 ppm of $O_3$ are expressed with the equation, E (%)=21.027 - 7.942 ln (T).

  • The rate of evolution of ethylent by tomato plants was rapidly increased by ozone fumigation. In the present study, the mechanism of ethylent evolution by ozone was investigated in experiments with aminoethoxyvinylglycine (AVG) and tiron, which inhibit the formation of ethylene and peroxidation of lipids, respectively. Pretreatment with AVG significantly inhibited the ozone-induced ethylent evolution, but the treatment of plants with tiron did not inhibit. These results indicate that the induction of the evolution of ethylene by ozone involves the pathway via aminocyclopropane-1-carboxylate (ACC), while not released as a result of the peroxidation of lipids. Ozone-induced ethylent evolution was greater in dar- than light-incubated, intact tomato plants. The difference between dark- and light-ethylene evolution was examined with diuron, an inhibitor of photosynthetic electron transport. The inhibitor treatment promoted ethylent evolution. These results suggest that ethylent retention and metabolism in plants were regulated by internal $CO_2$ levels which, in turn, were controlled in large part by photosynthesis. Thus, ethylene was retained in illuminated leaf tissue under low intenal $CO_2$ concentration which may develop in a sealed container without exogenously supplied $CO_2$.

  • In modem day Korea, the amount of records containing data, statistic etc are increasing dramatically. However, our country neglects to deal with these archives which include fields such as culture. Thus government documents, even modem documents less than 50 years old, are fading. becoming damaged and acidic. The purpose of this study is to research factors for prolongment the life of archival records, especially papers. Firstly, we want to maintain the document's original quality, which is a PH between 7 to 8.5, permanently. Secondly, our objective is to permanently maintain the records in a scientific environment. Thirdly, to execute proper repair methods by conservators. Permanent quality refers to the maintenance of a PH between 7 and 8.5 in a scientific environment whereby regulations are in effect to control the environment. These factors include constant temperature and humidity, breakors of various lights, Stable storage facilities which are fire resistent. A CCV control system as well as the dusting and fumigation of records. Finally, to conservate damaged papers based on exact diagnosis.
