톳, 미역 및 다시마를 용매별로 추출하여 이들 추출물의 항돌연변이원성을 검색하였다. 톳 용매별 추출물의 MMS에 대한 항돌연변이 효과는 TA100 균주에서 헥산, 에탄올, 에칠에테르 추출물 순으로 높았고, TA102 균주에서 헥산, 에칠에테르, 에탄올 순으로 높았으나, 미역 및 다시마 추출물은 항돌연변이원성이 거의 없었다. ICR191에 대한 항돌연변이 효과는 시험된 모든 시료에 대한 에탄을 추출물이 높은 항돌연변이 효과를 나타내었고, 에칠에테르와 헥산 추출물은 물 추출물보다도 낮은 효과를 나타냈다. 그러나 톳 추출물은 시험된 모든 용매 추출물에서 60% 이상의 높은 항돌연변이 원성을 나타내어 ICR-191에 의해 유도되는 돌연변이 원성을 저해하는 물질이 수용성 및 비수용성에 걸쳐 다양함을 나타내었다. 한편, 미역, 다시마 및 톳 추출물의 sodium azide에 대한 항돌연변이원성은 없는 것으로 나타났다. Desmutagenic effects against methyl methanesulfonate(MMS)-, 2-methoxy-6-chloro-9-〔3-[2-chloroethyl〕aminopropylamino〕acridine(ICR191)- and sodium azide-induced mutations by the extracts from Hizikia fusiforme. Laminaria japonica and Undaria pinnatifida with different solvents were investigated. The solvent extracts from Hizikia fusiforme were the highest desmutagenic effect against MMS in n-hexane and against ICR191 in ethanol extract. but no against sodium azide in all solvent extracts tested. While the solvent extracts from Undaria pinnatifida and Laminaria japonica were the highest against ICR191 in ethanol extract. but no against sodium azide and MMS in all solvent extracts tested. Moreover. all the solvent extracts from Laminaria japonica were inhibited 60% or more ICR191-induced mutations.

SLIS(Software License Integrated Solution) is composed of the 6 parts, Server Agent, Web Server, Client Agent, Client Manager, Service, and Install Shield. For the most part of the project is developed based on MFC platform except for the one, Client Manager, which is built on DDK(Driver Development Kit) and ASP. NET platform. Client Agent program installed on a customer's computer is implemented in 14 different classes. Its main function is able to limit and uninstall the purchased software by using teminateProcess. The purchased softwares expiration dates on customer's computer is being monitored by both Server agent and Client software itself. Client Manager hides the process of Client Agent program which shouldn't be killed by manipulating Process List in Kernel through DDK. To do this, Client Manager is internally implanted and registered in Windows Service to be ran as a part of windows system.

This study was conducted to analyze the morphological characteristics and genetic relationships among 24 species of Gerbera. Most of flower colors were pink. The numerical order of flower color was pink, orange, red, double-colored, and milk-white. Majority of flower types were single or semidouble flowers. A few species were double flowers. Flower diameters were from 7cm to 12cm, showed significant differences compared to other characteristics. Flower stalks were ranged from 55cm to 65cm. Only one species was the shortest as 55cm. The others were similar size as about 65cm. Main annual production yields were between 190 and 400 blossoms. Fifty seven reproducible polymorphic bands from eighty primers were used for analyses of genetic similarity. The genetic similarity of 24 collected Gerberas was largely classified into five groups. The average similarity coefficient was 0.72 ranged from 0.50 to 0.90. The highest similarity coefficient was shown between 'Sardana' with red/white flower color and double flower type, and 'Tamara' with orange flower color and double flower type as 0.90.

In organization and company managing a lot of computers, it is difficult to manage the computer system, because it is not easy to recognize exceptions of distributed workplace such as departments and laboratories. Existing computer management systems control many computers through manager using server computer for management in field. Therefore they have the characteristic of strong locality. In this paper, we develop computer remote control system which supports convenient features and non-locality to managers by broadening effective ranges of computer management. We use Web-Site and Android Platform to develop the environment of client management regardless of multiple clients and locality. Moreover, we use WMI (Windows Management Instrumentation) to recognize and control the status of client PC without a impact on computer users.

Primary intraosseous meningioma of skull is rare, and often confused with a primary bone tumor. We report a case of a 71 years old female patient with an intraosseous calvarial meningioma of frontal bone presenting as a solitary osteolytic skull lesion. Plain skull radiograph, CT and MR images show sharply marginated expansile bony lesion in frontal skull vault, and a small well enhanced soft tissue mass within bone. The mass is extracranially protruded to scalp, and is partially attached to the underlying dura. Outer and inner table of skull vault is slightly bulged out, suggesting intradiploic origin of the tumor. The tumor was treated with surgical excision and cranioplasty. Histological examination revealed fibrous meningioma.

Various methods were proposed for the measurement of biodegradability of polymer materials by American Society for Testing and Materials(ASTM). In those methods, carbon dioxide evolution, oxygen consumption, and the weight loss of polymer are measured for the evaluation of biodegadability when microorganisms grow by using the polymer material as the only carbon source. Since a month or longer time is needed to measure the quantities, a rapid quantitative mathod is required to be developed. We used α-amylase for determining the biodegradability of starch-filled polyethylene film: however, the enzyme reaction was so slow. Further studies on the reaction conditions are necessary for the rapid completion of the reaction. Therefore, starch content in the film was measured for the evaluation of biodegradability on the assumption that starch is a perfect biodegradable material. NaOH solution was used for the extraction of starch from the film and the weight loss of the film was measured.
