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.

수종의 치과용 수복재료 및 시멘트의 radiopacity

정현주,강병철,오원만,양홍서 大韓口腔顎顔面 放射線學會 1994 Imaging Science in Dentistry Vol.24 No.1

The radiopacity of six composite resins, three resin luting cements and ten filling materials were studied. The purpose was to obtain an indication of radiopacity value of different brands within each of these groups of materials and to show differences in radiopacities of filling materials and natural tooth structures. On radiographs, the optimal densities of standardized samples were determined by computer imaging system and radiopacity values of the materials were expressed in millimeter equivalent aluminum. Within the groups of materials studied, there was considerable variation in radiopacity. The composite resins of P-50, Z100 and Prisma AP.H displayed much higher radiopacities than aluminum. Panavia resin cement was shown to be similarly radiopaque to aluminum. Generally, the radiopacity of base and filling materials appeared to be higher than that of the enamel and dentin. If materials with substantial difference in radiopacity are used in combined applications for restorative treatment of teeth, lower radiopacity can interfere with the diagnosis and detection of gaps near the restoration.

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.

Most of closed fractures of the tibial shaft can be treated successfully with medullary nails. Reamed intramedullary nailing technique has become a good alternative method in treating the close tibial fracture. Unreamed interlocking intramedullary nailing has been employed successfully in the treatment of open tibial fractures. This study was undertaken to evaluate the result of interlocking intramedullary nailing without reaming in the treatment of closed fractures of the tibial shaft. From 1995 through 1998, fifty four cases of the closed, displace tibial fractures were treated by an unreamed intramedullary nailing and the average follow-up period was 1 year and 5 months(ranged from 12 months to 27 months). The results were as follows : 1. Fifty four cases were treated with closed, unreamed nailing technique and the nail which has 1mm smaller diameter than isthmic width of unaffected tibia was choosen. 2. The average time to bony union was achieved at 17 weeks without abundant periosteal b callus formation. 3. Eight tibiae were required the additional procedure such as autogenous bone graft, skin graft or local skin flap. We also have observed the screw breakage of ten tibiae but there were no intraoperative jamming or incarceration and no significant complicaton such as bending or breakage of the nail, shortening or non-union of the fractures. In conclusion, unreamed technique is an attractive method to treat the close, displaced fractures of the tibial shaft. 경골 간부 골절의 치료에 있어서 견고한 내 고정으로 조기 관절운동 및 체중 부하를 통해 골절 유합 및 기능 회복을 도모할 수 있는 골수강내 금속정 고정술이 널리 사용되어지고 있다. 골수강내 금속정술의 장점은 술 후 조기 관절운동과 체중 부하가 가능하여 이환율(morbidity)을 감소시키며 불유합의 발생률이 낮아는 것이다. 경골 간부 골절의 치료에 있어서 비확공성 금속정 고정술은 주로 심한 연부 조직 손상을 동반한 골절 및 개방성 골절의 치료에 적용되어지고 있으며, 대부분의 폐쇄성 경골 간부 골절의 치료로는 골수강 확공 후 골수강을 충만시키는 금속정을 삽입하는 확공정 금속정 고정술이 시행되어지고 있는 경향이다. 저자들은 폐쇄성 경골 간부 골절에 대해서 비확공성 금속정 고정술의 유용성 여부를 알아보기 위해서 동국대학교 의과대학 정형외과학교실에서 치료했던 54례를 평균 1년 5개월 추시하여 골 유합 기간, 합병증의 발생에 대해서 분석하였다. 본 연구에서 비확공성 금속정 고정술시 골 유합 기간은 확공성 금속정 고정술시와 비교하여 유의한 차이가 없음을 알 수 있었으며, 확공을 하지 않음으로써 발생할 수 있는 jamming이나 가는 직경의 금속정을 선택함으로써 우려되는 금속정의 휨, 부러짐 등의 합병증은 발생하지 않았다. 결론적으로 폐쇄성 경골 간부 골절의 치료에 있어서도 비확공성 골수강내 금속정 고정술은 유용한 방법으로 사료된다.

This study was undertaken to compare the storage characteristics between veal sausage and commercial pork and beef sausages in Korean domestic market. We manufactured 3_types of sausages and purchased 2_types of sausages in the market: T1(B-company product), T2(O-company product) and we made T3(smoked veal sausage), T4(smoked veal sausage with pepper) and T5(cooked veal sausage) products. During 20 days of storage at 4oC, T5 showed significantly higher in TBA value and VBN value (p<0.05). But TBA and VBN values showed normal range in all products. T3, T4, and T5 showed higher total microbial count than T1 and T2 (p<0.05). According to the result, beef and pork sausages in the market showed different total microbial count and VBN values from those made in laboratory. This result could be come from the different additives used and manufacturing processes. However, all products can be stored up to 20 days in the cooler.

프롤린 함량 증가 및 내건성 강화 관련 새로운 RING-Type E3 유비퀴틴 리가아제 애기장대 atrzf1 돌연변이체의 생리적 기능 연구

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.
