오늘날 현저한 CO2 레이저의 응용 추세에 발맞추어 보다 다양한 형태의 출력 제어 기술이 대두되고 있다. 본연구에서는multi-Pulse Superposing-Discharge 기술을 이용하여 다양한형태의 CO2 레이저의 펄스를 성형 하였다. 펄스 성형을 위한 방법으로 PIC one-chip microprocessor를 이용하여 삼중 PFN 모률의 SCR을 각각 고유의 지연시간을 가지도록 제어하였다. 실험에 사용된 삼중 PFN 모률의 전원 회로는 각각 캐패시터 인덕터,SCR,고압 펄스 트랜스 그리고 고압 트랜스 2차측에 브릿지 정류기로 구성 하였다. 고압 펼스 트랜스의 1차측을 제어하므로서 PFN 모률의 동작을 저 전압에서 수행 할 수 있다. 트랜스의 2차측에 연결된 전파 정류기는 펄스 에너지를 부하에 지속적으로 전달한다. 본 연구에서는 삼중 PFN 모률의 각각의 SCR을 다른 시간 가격을 두고 트리거 하므로서 다양한 Long pulse shaping을 실현하였다. 또한 약 250-1000μs 의 주기를 가지는 다양한 펄스형 레이저 빔을 얻었다.

Some allylamine compounds which are benzothiazole substituants in stead of naphthylring in naftifine, antifungal agents, were sythesized as potential antimycotics. The intermediate Schiff bases that were obtained by condensation of 2-aminobenzothiazole and trans-cinnamaldehyde, were reduced to imine compounds to give allylamines(5a-5d) after mrthylation. These compounds which were tested in vitro against five fungal cell lines containing Trichophyton mentagrophytes. showed no activity in 0.1∼100 μg/ml range.

The covalent attachment of ubiquitin to proteins plays a fundamental role in the regulation of cellular function through biological events involving abiotic of biotic stress responses, immune responses, and apoptosis, Here, we characterize the biological function of the Arabidopsis thaliana RING Zinc Finger 1 (AtRZF1) in dehydration response. AtRZF1 was significantly reduced by drought stress. The atrzf1 mutant was less sensitive to osmotic stress than the wild-type during early seedling development, wheareas transgenic pants overexpressing AtRZF1 were hypersensitive, indicating that AtRZF1 megatively regulates drought-mediated control of early seedling developmeng. Moreover, the ectopic expression of the AtRZF1 gene was very significantly influential in drought sensitiv parameters including proline content, water loss, membrance ion leakage and the expression of dehy-dration stress-relat genes. ARZF1 is a functional E3 ubiquitin ligase, and its conserved C3H2C3-type RING domain is likely important for the biological function of AtRZF1 in drought response. Together, these results suggest that the E3 ligase AtRZF1 is an important regulator of water deficit stress during early seedling development.

주재익,정현주 전남대학교 치과대학 1995 전남치대논문집 Vol.7 No.1

The purpose of this study was to evaluate the bacterial adherence on e-PTFE membrane immersed in whole saliva from subjects with different periodontal status. Experiment involved 3 subjects groups : 5 persons with healthy periodontium(probing depth below 3mm and no signs of gingival inflammation including bleeding on probing), 10 patients with gingivitis(probing depth below 3mm and apparent signs of gingival inflammation), and 10 patients with advanced periodontitis(probing depth over 7mm and apparent signs of gingival inflammation). Each disease group was included before and after scaling and root planing treatment. After obtaining whole saliva from each subject, e-PTFE membrane(Gore-Tex periodontal membrane : GTPM??, W.L. Gore & Associates, Flagstaff, USA) specimens were immersed at room temperature in the saliva aliqouts for 1, 3, 7 days. The weight between pre-and post-immersion in saliva was measured with the analytical balance and the difference was recorded. The specimens were processed for SEM observation. The bacterial adherence on the membrane specimens was evaluated using the scanning electron microscope images. The obtained results were as follows : 1. There was no difference in the weight of bacteria adherent to e-PTFE membrane specimens according to the periodontal status and the immersion periods. 2. As the exposure time to saliva increased, the bacterial adherence to the membrane specimen significantly increased in all groups(P<0.005). 3. As the severity of periodontal disease increased, the bacterial adherence to the membrane specimens significantly increased(P<0.001). 4. After scaling and root planing, the bacterial adherence to the membrane specimens significantly decreased in gingivitis and periodontitis patient group(P<0.001). These results suggest that bacterial contamination on exposed barrier membrane surface be reduced through improvement of periodontal status and oral health environment before and after GTR procedure for the successful outcome.

정주영,이만우,조강현,최병희 한국환경생물학회 2000 환경생물 : 환경생물학회지 Vol.18 No.3

해안생태공원 조성이 추진중인 인천광역시 논현동 일대 염습지의 식물상 및 식생을 1999년 6월부터 2000년 6월까지 조사하였다. 이 지역에는 소래포구의 조간대를 따라 발달한 자연염습지와 함께 조수가 차단된 폐염전이 있다. 이 지역에서 14종의 염생식물이 조사되었는데, 그중 해홍나물이 가장 많이 분포하고 있었으며, 그밖에 퉁퉁마디, 비쑥, 갯개미취 등도 많이 관찰되었다. 폐염전에서 관찰된 염생식물의 종류는 자연염습지에서 조사된 것과 매우 유사하였다. 그러나, 폐염전과 자연염습지 사이의 제방지역은 염습지 보다 다양한 종이 자라고 있었는데, 귀화식물도 21종이 관찰되었다. 자연염습지의 식생은 해홍나물-비쑥군집과 해홍나물군집으로 구성되어져 있으며 지역에 따른 큰 차이는 없었다. 한편, 폐염전에서는 해홍나물-퉁퉁마디, 나문재-해홍나물, 갈대-애기부들, 갈대군집 등 다양한 군집이 조사되었다. 식생상관과 종다양도에 기초하여 조사지역을 식생양호지역, 인간활동에 따른 교란지역, 식물고사지역 등의 세 구역으로 나눌 수 있었으며, 해안생태공원 조성에 따른 각 구역의 보존대책을 제시하였다. The flora and vegetation of salt marsh region in Nonhyun-dong, Incheon were investigated from June 1999 to June 2000. The surveyed region includes the several abandoned salt farms and natural salt marshes developing along the intertidal zone at the stream of the Sorae Inlet, Yellow Sea and is going to be constructed a costal ecopark. In this survey 14 species of halophytes were collected in the region, among them Suaeda maritima is the most common one, Salicornia herbacea, Artemisia scoparnia and Aster tripolium are also observed popularly. The flora of the abandoned salt farms is very similar to that of the natural salt marshes. However, the bank areas between the abandoned salt farms and the natural salt marshes showed more richness of species diversity including 21 naturalized plants. The vegetations on the natural salt marshes are mainly composed of Suaeda maritima-Artemisia scoparnia and Suaeda maritima communities. On the other hand, various plant communities were investigated in the abandoned salt farms such as Suaeda maritima-Salicornia herbacea, Phragmites communis-Typha angustata, Suaeda asparagoides-Suaeda maritima and Phragmites communis communities. Based on the plant physiognomy and species diversity, the region can be divided into three types of area for conservation, that is, the area composed of well-developed vegetation, disturbed one by human activities and plant withering area. Futhermore, according to the construction of the costal ecopark in the region the conservation scheme for each area was discssed.
