Background : The genus Cypripediums are typically adapted to the low temperature and cold climates of the high land in Korea. The species which were reported in Korean peninsula are C.japonicum, C.macranthos, C.calceolus and C.guttatum. We had already reported the successful germination of the C.macranthos and C.guttatum. The small spotted lady's slipper orchid(C.guttatum) is most endangered plants to extinction of which population was reported less than 100 in Korea. The objective of the present research is restoration of the C.guttatum in ex situ and adaptation in high land and nursery. Methods and Results : The 350 seedlings of C.guttatum were transplanted in soil at alpine area(altitude 750m) and the nursery of Korea National Arboretum(KNA) in YangPyeong city on May 2019 and 2020 in order to verify the possibility of ex situ restoration. The sprouted ratio of the seedlings were less than 10% in the alpine area and 83% in the nursery of KNA. The reasons of the diverse survival ratio are presumed as the low moisture content in the soil and heavy shade of the alpine area. The 15 cypripedium species and 29 hybrids were also effectively adapted in the KNA rare plant garden. Conclusion : These results demonstrated the difficulties of the restoration for small spotted lady's slipper orchid in the natural habitation. From the above results, we may conclude that the critical factors of the genus Cypripedium are intensive care for the fragile seedlings during the 1^st year acclimatization.

Chungnam-Do is the major agricultural province, supplies the large amount of rice and has the best situation in rice production. Rice production in Chungnam region is the major income source of farmers in the Chungnam province. In spite of the best quality, the rice quality which is produced in Chungnam province has been underestimated. For the improvement of this situation. Chungnam local government has developed the 'Cheong-Pung-Myeong-Wall' brand. The objective of the study is to give marketing information on 'Cheong-Pung-Myeong-Wall' rice for its sales promotion. The survey data on consumption patterns of consumers in the Taejon city who consume the 'Cheong-Pung-Myeong-Wall' rice were used in the analysis. The conclusions of this study may be summarized as follows : Generally the people who live in the Taejon city and consume the 'Cheong-Pung-Myeong-Wall' rice satisfy its quality, but the sales promotion of 'Cheong-Pung-Myeong-Wall' rice is needed For the sales promotion of 'Cheong-Pung-Myeong-Wall' rice, diversification of products, efficient usability of market agency, improvement of packing design, adequate advertisement, guarantee of 'Cheong-Pung-Myeong-Wall' rice taste and food safety, introduction of differentiated price by the producing region are required.

The effects of temperature on nitrification of enriched nitrifiers were investigated by using kinetics and thermodynamics method through the batch test. Aquaculture recirculating water, which was sampled at Chung Cheong Buk-Do Inland Fisheries Research Institute, was analized to observe the characteristics of nitrification. Temporal variation of ammonium, nitrite and nitrate concentration was measured at batch experiments. Activation energy was calculated using Arrhenius equation with the oxidation rates of specific ammonium or nitrite ion. These oxidation rates were measured at temperature range of $6-35^{\circ}C$ and ammonium concentration range of 0.2-1.8 mg/L. Two distinct activation energy of Nitrosomonas sp. at temperature $6-15^{\circ}C\;and\;15-35^{\circ}C$ was 93.1 and 25.0 KJ/mol, respectively. Nitrate accumulation was observed at temperature over $15^{\circ}C.$

With regard to Gung-jung Yeon-hyang(宮中宴享; court banquet), the frequency of banquets that were held at one time beginning Mu-ja J in-jak(戊子進爵; a royal banquet held in 1828) in 1828 (the 28th year of King Sunjo (純祖)'s reign). In proportion to this frequency, there was an increase in the need and importance of Suk-seol-so(熟設所; a kitchen built in temporarily house for court banquet) and Jung-bae-seol-cheong(中排設廳; a temporary place to put offerings) as a space to assist court banquets. Although Suk-seol-so was a temporary but large-scale facility, it was frequently used for long periods. This facility was flexibly established using the variability of Dong-gung(東宮; Palace for Crown Prince) and enhanced the efficiency of censorship and security in conjunction with palace gates and Suk-wi-cheo(宿衛處; guard station, guard room). In addition, it was reused according to the period when the nation and royal family gave finances or banquets. Jung-bae-seol-cheong was established in the place connected to the central space of court banquets and worked as buffer space to resolve the tension on the day of the event. The location where Jung-bae-seol-cheong was established enabled us to confirm the applicability of Bok-do(複道; corridor) connected to Chimjeon(寢殿; royal residence) when holding court banquets. In short, Suk-seol-so and Jung-bae-seol-cheong were auxiliary spaces, but were considered importantly in the palace operation when holding court banquets.

This landscape design proposal was presented to a design competition for Osong Biohealth Technopolis Institute of Cheongwon Gun Chung Cheong Buk Do which was held by Ministry of Health and Welfare in March 2004. The site is located in. Osong Li, Kang Wei Myun, Cheonwon Gun, Chung Cheong Buk Do and has an area of $402,600m^2$. The judging criteria for landscape design set by the client could be articulated as follows: an environment friendly design respecting the surrounding environment, a functionally efficient site plan by clustering buildings with similar uses, a site plan having 'front yard' by locating buildings in rear areas toward existing 'groves'. The proposal set the main design concept of this project as 'clustering'. By doing that, existing grades and plants can be saved, buildings with similar uses can be clustered, huge 'front yard' as a symbolic image of this project can be achieved, and finally many small open spaces for everyday life can be designed accordingly.

Daegeum is the only Korean musical instrument that uses cheong The characteristics of cheong have to be considered first for the sound synthesis of daegeum. This study analyzes the changes of partials in accordance with the vibration of cheong. It shows that amplitudes differ at the partials after about the seventh partial. The study also found that, unlike the case of partials, the vibration of cheong has nothing to do with noise. We expect that this study results can be applied to the sound synthesis of daegeum.
