CO2 Enrichment plays a key role in a greenhouse for yield and plant quality. This study deals with variation of atmosphere in the greenhouse during CO2 enrichment by a catalyst-type CO2 generator and it generates 0.36 kg/h. There are Alstromeria in a inner-greenhouse which was set in a main greenhouse for prevent damage from cold. The CO2 generator turned on at every 5:30 a.m and turned off at every 12:30 p.m. And inner-greenhouse was opened among 8:00 a.m ~ 9:00 a.m manually. The window of main greenhouse was opened when temperature in greenhouse was above 20 ℃ automatically. CO2 concentration increased to about 700 ppm, and then sharply decreased under 400 ppm after opening the inner-greenhouse. Furthermore, at first, the CO2 concentration rose dramatically to ‘some point’ which is near the sunrise, and then rose gently. This phenomenon implies the photosynthesis started on ‘some point’. It means CO2 consumption increased and the ratio between CO2 consumption and generates was change at that point. In addition, the rate of increase in CO2 concentration became more gentle as the experiment progressed. This result imply the amount of photosynthesis increased gradually because of leaves growth.

시설 내 탄산가스 시비 시 시설 대기환경의 변화가 알스트로메리아(Alstroemeria) 생육에 미치는 영향에 대한 고찰

CO<sub>2</sub> fertilization is very critical for plants in a greenhouse because CO<sub>2</sub> is insufficient after sunrise due to the photosynthesis. This study reported the variation of CO<sub>2</sub> concentration in greenhouse and the effect of greenhouse plants on CO<sub>2</sub> fertilization. Alstroemeria were cultivated in CO<sub>2</sub> fertilization greenhouse and non- CO<sub>2</sub> fertilization greenhouse (Control house). To supply CO<sub>2</sub>, we set a catalyst-type CO<sub>2</sub> generator at fertilization greenhouse and it generated 0.36kg/h CO<sub>2</sub>. The CO<sub>2</sub> concentration at CO<sub>2</sub> fertilization greenhouse was maintained about 640 ppm from 6:00 to 10:00. The result reported that CO<sub>2</sub> fertilization significantly increased the weekly yield and shoot length. There was slightly increase at total number of flowers and stem thickness despite of no statistical significance. According to these positive results, we considered that future studies would be aimed at experiments with bigger scale and more details.

동국대학교 박물관 소장 <부석사명 철제은입사향완> 연구
이선진(Lee Seonjin) 동국대학교 박물관 2022 佛敎美術 Vol.33 No.-
The silver inlaid iron incense brazier(University of Dongguk Museum) with the inscription of Buseoksa Temple and its height of 37cm is the unique peace on which inlaying technique on pecked iron surface is applied for decorating patterns in the incense burners. It obtains inlaid letters of ‘己未年三月日(March kimi Year)’ on the upper part surface, which addresses to the year of 1739, and ‘Buseoksa’ meaning Buseoksa Temple in Teabaik Mountain, on the lower part. In the bottom of the brazier pole, the names of manufacturer are engraved in the shape of trapezoid with longer vertical height. On the name list, 李弘成(Lee hong sung) is found and regarded as leader technician in the burner manufacturing. According to the record of 儀軌(the royal protocols of Joseon Dynasty) he was affiliated to hunguk with the title of 入絲匠(master technician in inlaid skill), and also assigned to 寶匠(made the royal seals) as a 京工匠(made them for the royal court). On this background, he could invent new type of incense burner and produced it differ from the e×isting type of bronze incense burner. In relation to the Buseoksa Temple incense brazier, three pieces of silver inlaid iron incense brazier(Buddhist Museum of jikjisa Temple) are the cases of temple made caldronshape burner with letters of chronological data and names of patrons. The inscriptions illuminates the fact that 泰鑑(Taegam, 1690-1769), a master monk, supported to produce the silver inlaid iron incense burners in 1750. All the three burners are identical with the height(35cm), formation, patterns, and even the inscriptions. Assuming the monk Taegam served in the post of Sueocheong of which mission devoted to defend Namnansanseong, the manufacturer can be inferred a technician belonging to Ogunyeong. This paper aims to analyze the formations of iron incense braier and iron censer, and, then, inlaying technique on pecked iron surface and the applied patterns. In addition to the comparative analysis between jikjisa Temple silver inlaid iron incense brazier and Buseoksa Temple silver inlaid iron incense brazier, research on governmental manufacture organizations and management process of products in each special technique in eighteen century will be a fundamental ground in this study.
