In the existing web service environment, the service that is provided after verifying identities at the step of user identification and authentication was in the majority, but the authorization step is most important in the service environment that provides IT infrastructures like cloud computing services. Due to the characteristics of the cloud computing service, the user authentication has to be led to the authentication technology for the user authority management. In this paper, we designed a suitable authorization method that can guarantee sufficient controls and personal information protection about the user information by designing to combine SSO(Single Sign On) and PKI(public-key infrastructure).

Cadmium-resistant bacterium was isolated from Anyang-river on agar plate media containing 100 ppm of cadmium chloride. The characteristics of the isolated strain were consistent with that of genus Pseudomonas. It showed multi-resistant to various heavy metals including mercury, lead and copper. The effects of cadmium on the bacterial growth were measured by turbidity, viability and ³H-glucose uptake rate. In the early stage of growth, the viability and the physiological activity were rapidly decreased by the toxicity of cadmium. But after 3 hours, the bacterium began to grow exponentially and the activity became almost equal to that of the control without cadmium. The isolated strain had broad-spectrum resistance to various antibiotics such as ampicillin, chloramphenicol, kanamycin, streptomycin and tetramycin. It seemed that the resistance to cadmium is genetically controlled from the results that the isolated strain maintained high activity under high concentration of cadmium and showed multi-resistance to antibiotics.

Die Praimplantationsdiagnostik hat die Chance geschaffen, Embryonen im Rahmen der In-vitro-Fertilisation zu untersuchen, bevor sie ubertragen werden. Genetisch kranke Paare haben dann die Moglichkeit zu erfahren, ob der Embryo unter einer erheblichen Erbkrankheit leidet. Man kann auch mit Praimplantationsdiagnostik Informationen erhalten, ihren Wunsch nach einem gesunden Kind jedenfalls zu realisieren. Es bestehen die aktuelle Gefahr, daß es zu willkurlichen Selektionen kommen konnen. Menschliches Leben, auch wenn es noch nicht individuelles Leben ist, darf jedoch nicht willkurlich selektioniert werden. Trotz der bestehnden Mißbrauchsgefahr ist es kriminalpolitisch nicht sinnvoll, die Praimplantationsdiagnostik absolut zu verbieten. Man kann die Praimplantationsdiagnostik an die Zulassungsvoraussetzung knupfen, daß ein konkreter Verdacht auf eine Erbkrankheit bei dem Embryo besteht und kann sie auch im Hinblick auf Untersuchungsmethoden begrenzen. Daß Tatsachen die Moglichkeit eines erheblichen Erbschadens bei Embryoen befrunden, sollte als Zulassungsvoraussetzung fur die PID gesetzlich formuliert werden.

암모니아와 아민류가 주된 악취원인 실가동 분뇨처리장의 악취가스를 생물탈취탑에서 처리하기위한 연구의 일환으로 다양한 비율의 소나무 껍질, 분변토, 퇴비로 구성된 생물여재를 적용하는 탈취탑 여재내의 세균 분포 및 특성을 조사하였다. 153일간 사용한 탈취탑내 여재(이하 사용후)와 악취처리에 사용하지 않은(이하 사용전) 여재 각각을 대상으로 하였다. 그 결과 사용전 여재는 질산화한천 배지, 황산화한천 배지, 표준한천 배지 상에서 g당 $10^7{\sim}10^8$ 수준의 세균이 존재하였고 사용후 여재 역시 $10^5{\sim}10^7$에 이르는 다량의 세균이 존재하였다. 또한 질산화한천 배지에서 사용전 여재와 사용후 여재 모두 큰 차이 없이 간균과 구균이 존재하였다. 종속영양 세균 총 45주를 분리하여 동정한 결과 Pseudomonas, Bacillus, Flavobacterium, Alcaligenes속 등이 분리되었으며, 그 중 21주는 질산화한천 배지 상에서 집락을 형성한 것을 표준한천 배지에서 재 분리하여 동정하였는데 표준한천 배지 상에서 직접 분리한 분리주보다 Alcaligenes가 특징적으로 많이 분리되었다. Alcaligenes는 사용후 여재에서 높은 비중으로 검출되었고, 처리가 우수한 분변토 혼합여재에서의 검출비중이 소나무껍질여재보다 높아 생물탈취처리의 기여도가 높은 것으로 사료되었다. The distributions and characteristics of bacteria on the deodorizing biofilters were studied as a part of biofiltration research for odor gas removal. The odor gas originated from a currently operating nightsoil treatment plant were mainly nitrogenous compounds of ammonia and amines. The filter media were consisted various ratio of pine bark, nightsoil cast and compost, and were sampled before and after operation of 153 days. Before operation, the level of bacteria on nitrification agar medium, nutrient agar medium and thiosulfate agar medium were around $10^7{\sim}10^8cfu/g$ media. After operation, the level decreased but still high as $10^5{\sim}10^7cfu/g$ media. The bacteria from reactors before and after operations were either rod or coccus after growth on nitrification agar media. The 45 isolated heterotrophic bacteria were further characterized and Pseudomonas, Bacillus, Flavobacterium, Alcaligenes were dominant genera. Genus Alcaligenes was particularly dominant when the isolates were incubated on nitrification agar media first and then transfered to nutrient media. The portion of Alcaligenes in the biofilter increased after operation, and was higher in the media contained nightsoil cast, which showed better treatment than the media with pine bark only.

Today, Leggings are highly fashion items have body fit, and complex-functionality. and expanding their territory to outdoor and leisure fields. The purpose of this study was to improve the efficiency of raschel lace leggings. For this study, made 8 samples and to analyze them. They were 4 kind of knee length, 2 kind of capri length and ankle length. The results of the study are as follows: First, clothing preassure of leggings were good level of all kind of leggings samples. Second, their level of aesthetics of leggings with the pattern of mild, soft and luxurious feeling was high, whereas the level for great and strong color patterns were relatively low. Third, length of leggings was knee-length was most satisfaction than capri-length and ankle-length. Fourth, nylon yarn knitted products were high degree of satisfaction of wearing and lightweight.
