Growth and tuber development of ‘Black Magic’calla lily as affected by the rain shelter with 50％ shading and the tuber size were investigated. Tubers of five grades in size were cultivated in the rain shelter or in the open field (control). Days to emergence of shoots in the rain shelter was accelerated by 4.2 days as compared to the open field. Emergence ratio was higher as the tuber was larger, tubers grown in the rain shelter showed the significance in the growth characteristics as compared to the control. There were no significant differences in the number of flowers per tuber between the rain shelter and the open field. Flower quality was 12.2 cm longer than that in the open field. flowering characteristics was improved with the increasing tuber size. Low infection of soft rot disease of 3∼22％ was found in the rain shelter as compared to the that of 19∼83％ in the open field. Thus tubers produced under the rain shelter showed improved quality, Even if the small tubers with diameters of 0.5∼1.0 cm were cultivated in the rain shelter, the weight and diameters of tuber harvested after approximately 7 months were 50.2 g and 5.7 cm, respectively.

This study was conducted to investigate the plant growth and seed yield between rain-shelter plastic house and out-door cultivation, and analysed the effect of harvesting time on seed quality. In rain-shelter plastic house cultivation, emergence date was 3 days and flowering date was 8 days earlier than out-door cultivation. Seed yield of rain-shelter plastic house cultivation was increased $25\%$ compared to out-door cultivation and it's more beneficial than out door cultivation. The crude fat content was higher and seed was whiter and better quality in rain-shelter plastic house cultivation than out-door cultivation. In out-door cultivation, the crude fat content was steadily increased until 40 days after full bloom, but the seed color was getting dark which was harvested at 30 days after full bloom and the color was turn to the dark brown when the seed was harvested at 40 days after full bloom. Harvesting of safflower seed's quality is best between 20 days and 30 days after full bloom.

Owing to the energitic studies of the leading shcolars, some paradigmatic theories on the history of Korean dwellings have been suggested. They constructed periodization of their own and defined characteristics of each period with very limited historical materials. However the new historical materials have been discovered in the neighboring academic fields, which require to review the existing theories. This study aims at restructuring periodization in the history of Korean dwellings during the age of The prehistory and The ancient Kingdomes. Through the study, the existing theories on the same period are revived and evaluated based on the new materials. I suggest a new theory on the periodization and the characteristics of each period: a. the paleolithic period(6,000,000 B.P.-10,000 B.P.) : natural shelter, the emergence of man-made dwellings b. the neolithic period(10,000 B.P.-1,000 B.C.) : construction of pit house c. the bronze period(1,000 B.C.- 300 B.C.) : construction of semi-pit house d. the early metalic period(300 B.C. - 300 AD.) : construction of house on the ground level development of the Ondol system e. the ancient kingdomes period(300 AD - 700 AD): classification of housing type

In Korea, to deal with the housing needs of the elderly, the government operates free nursing homes and residential homes. And to deal with the needs for daily necessities, imported products or products for the disabled have been supplied for the elderly. The government has recognized the importance of silver industry in this rapidly aging society and has established strategies to vitalize industries related to seniors to deal with the seniors' need for food, clothing, and shelter. This study examined the necessity of nursing home gowns, and the development of nursing home gowns that are environmentally friendly, beautiful and functional for the new silver generation. For this study, literature review and Internet search were conducted regarding the status of silver fashion, necessity of nursing home gowns, emergence of new silver generation and change in lifestyle, and value and utilization of natural dye and traditional patterns. To produce nursing home gowns, fabric was dyed using fermented indigo dying, and 3 styles of nursing home gowns for each gender were designed in consideration of seasons. Lastly, these gowns were evaluated by fashion experts, medical personnel, hospital gown and silver wear experts, and natural dye experts. The results showed that the traditional Korean designs developed in this study were excellent and the fermented indigo dye was appropriate for the nursing home gowns. The development of nursing home gowns in this study will be utilized as basic material for the development of silver wear and nursing home gowns to improve the quality of life for the seniors.

This study was performed to investigate antimicrobial resistance in bacterial isolates obtained from companion dogs in veterinary hospitals and an animal shelter in Incheon. Drug resistance was examined respectively with the isolates of Escherichia coli, Enterococcus faecalis, and Staphylococcus pseudintermedius. The prevalence of drug resistance was calculated for each bacterial species towards 163 E. coli isolates, 156 E. faecalis isolates, and 86 S. pseudintermedius isolates by using selected antimicrobials. E. coli isolates were highly resistant to ampicillin, ciprofloxacin and tetracycline (47.9%, 28.2% and 28.2%, respectively). E. faecalis isolates were highly resistant to quinupristin-dalfopristin, tetracycline, kanamycin, rifampicin (69.8%, 66.0%, 53.8% and 51.9%, respectively). Higher levels of resistance were detected for ampicillin, penicillin, tetracycline, erythromycin, trimethoprim/sulfamethoxazole, telithromycin in S. pseudintermedius isolates (83.7%~52.6%, respectively). Occurrence of methicillin-resistant S. pseudintermedius (MRSP) was confirmed by oxacillin disc diffusion method, resulted in 23.3% occurrence among the S. pseudintermedius isolates (20/86 strains). The occurrence ratio of multidrug-resistance in the isolates of E. coli, E. faecalis, and S. pseudintermedius was 34.5%, 56.9%, and 67.9%, respectively. In this study, higher levels of antimicrobial drug resistance were observed in bacterial isolates obtained from dogs in Incheon. A regular monitoring and surveillance program should be implemented to prevent the emergence and spread of the drug-resistant bacteria carried in companion dogs.

This study was conducted to examine characteristics of rhizome growth and flowering of white lotus (Nelumbo nucifera) plant in Muan Hoesan-lake for collecting the basic data on the cultivation and the flowering which is growing in Muan Hoesan-lake of Jeonnam province in Korea. We have planted from the seeds and the enlarged rhizomes of the white lotus which were planted in the plastic containers on April 20 and May 4, 2008, and cultivated under rain shelter condition. Rhizome growth pattern and the flowering characteristics of the white lotus were examined on September 4, 2008. Main rhizomes of the white lotus propagated by the seeds and the enlarged rhizomes were branched by 10% and 15%, respectively. Numbers of nodes in the bloomed and non-bloomed rhizomes of the white lotus were over 14 and below 11, respectively. Flower was not observed in the white lotus when propagated with seeds, however, flowers came out up to 80% by the enlarged rhizomes. First flowers were bloomed from the late July and to the early August, and the number of flowers were 4.0~4.4. The first flower stalks without branching of the main rhizome were emerged in 8.8th node, however, that with branching were 8.0th node. Time to flowering from the emergence of flower stalk on the above-ground parts were required 16 days. White flowers from the lotus were 15.3 cm in height and 28.2 cm in width, their longevity was 3.3 days and the averaged flower fresh weight was 29.2 g. The results conclude that optimum number of nodes on the main rhizomes for blooming the white lotus flowers should be over 8 nodes before the rhizome enlargement.
