노준형,김영홍,류봉기 부산대학교 환경문제연구소 1999 環境硏究報 Vol.17 No.1

The photocatalyst of TiO_2 coated onto glass bead was prepared from sol-gel method. The solids were characterized by X-ray diffraction (XRD), specific surface area (BET), and scanning electron microscopy observation (SEM). The gas-phase photocatalytic degradation of trichloroethylene (TCE) and benzene with coated TiO_2 on glass beads was investigated using a fixed bed reactor. At steady state, conversion yields were obtained for trichloroethylene (ca. 82%) in 400 ppm concentration and benzene (ca. 65%) in 300 ppm. In order to compare the TiO_2 powder for the photocatalytic reaction efficiency, two different powders were used. To obtain higher efficiency, it was the primary factor to select the TiO_2 powder. Through the experiments, the photocatalytic degradation had the behavior of Langmuir-Hinshelwood kinetics as function of reaction time.

이준호,유영기,노병옥 선문대학교 ·중소기업기술지원연구소 2002 선문공대 연구/기술 논문집 Vol.7 No.1

접촉식 지문인식기에 사용되는 접촉발광소자는 투명전극층, 발광층, 기판층으로 구성되어 있고, 접촉발광소자의 기판부분에 지문이 접촉될 경우 전계(Electric Field)가 형성되어 빛을 발하게 된다. 이때 접촉발광소자에 발생되는 빛이 소자 전체에 균일하게 발생하여야 양질의 이미지를 획득할 수 있다. 본 논문에서는 이러한 특성을 검사하기 위해 비젼 시스템을 이용하여 접촉발광소자의 외형치수, 전계형성의 균일성, 지문영상의 대조 및 외부 조명에 의한 투과도 등의 센서의 성능을 검사하는 방법에 대하여 연구하고자 한다. CLED (Contact Light Emitting Device) has three layers consisting of a transparent electrode, a light emitting layer and a substrate. When the substrate of the CLED comes in contact with a fingerprint under AC input voltage, it makes an electric field between the fingerprint and the device. Due to the electric field, the light is emitted along the ridgeline of the fingerprint. The intensity along the ridge on the surface of the CLED increase in proportion to the electric field. To achieve the uniform performance of fingerprint verification devices, inspection system of CLED for quality control were required. In this research, we proposed the factors for quality controls such as dimensions of the CLED, uniformity, contrast, brightness and transmission. In addition, we realized the inspection system that is measured the quality control factors.

이준호,유영기,노병욱,이수진 선문대학교 ·중소기업기술지원연구소 2002 선문공대 연구/기술 논문집 Vol.7 No.1

최근들어 3차원 가상현실의 발전과 더불어 동작을 트랙킹하는 모션캡쳐는 엔터테인먼트, 의학, 스포츠, 교육, 산업등에 다양하게 널리 사용되어지고 있다. 특히 엔터테인먼트분야의 애니메이션과 게임등에서는 캐릭터의 생성에 모션캡쳐 기술을 사용하는데 기존에는 마우스, 조이스틱, 미디 슬라이더(Midi Sliders) 및 기타 장치들을 사용하여 캐릭터를 직접 연기시키는 방법을 사용하였으나 모션캡쳐에 의한 방법은 이전에 볼 수 있었던 그 어떤 방법보다도 자연스러운 움직임을 만들어낼 수 있다. 본 연구에서는 캐릭터를 연동한 온라인 3D 게임을 실현하기 위하여 광센서를 이용한 저가이면서도 빠른 샘플링 빈도를 갖는 모션캡쳐 시스템을 개발하고자 한다. Motion trackings are being used in part of the entertainment, medical, sports, education and industry with the development of 3D virtual-reality. In particular, the technology is used for animation and games as a part of entertainment. We can make very smooth motion that was never realized before, if we use the technology instead of using mouse, joystick, midi-sliders and so on for making some characters. In this research, we have developed a very low priced and fast sampling system using optic sensors for capturing the motion.

한현주,박래백,임영민,김효성,박경수,노영복 조선대학교 기초과학연구소 1990 自然科學硏究 Vol.13 No.1

살모사(Aekistrodon halys Pallas)의 위장관 점액세포내 점액질을 활동기와 동면기로 나누어 조직화학적으로 비교관찰하였다. 일반관찰을 위하여 H-E 염색을, 조직화학적 소견을 관찰하기 위하여 PAS reaction, Ab2.5 염색, AB1.0염색, AB2.5-PAS 염색, AB1.0-PAS 염색 AF1.7 염색 및 AF1.7-AB2.5 염색등을 시행하였다. 위(胃)는 표면점액세포와 점액경세포의 점액질을, 소장은 은롸롸 융모의 점액세포를 관찰한 결과를 다음과 같이 요약하였다. 1. 활동기와 동면기의 위점막에서는 현저한 차이는 없으나, 소장점막은 동면기에는 점막 주름수가 감소하고 높이가 낮아지며 점액세포가 위축되었다. 2. 위 표면점액세포는 활동기에 중성점액질과 약간의 Sialomucin을 포함한 산성점액질로 구성되었으나, 동면기에는 중성점액질과 Sialomucin이 약간 감소하였다. 3. 위 점액경세포는 활동기에 중성점액질만을 포함하고 있었으나, 동면기에는 Sialomucin을 포함한 산성점액질이 소량 검출되었다. 4. 소장 점액세포는 활동기에 산성점액질과 중성점액질로 구성되었으며 산성점액질에는 Sulfomucin과 Sialomucin이 포함되어 있었으나, 동면기에는 Sulfomucin과 Sialomucin이 다소 감소하였다. This study was performed in order to investigate the histochemical properties and compositions of the mucosubstances in the mucous of the gastrointestinal tract of Vipers, Agkistrodon halys Pallas, in active and hibernating phases. The specimens from stomach and small intestine were fixed in 10% neutral buffered formalin, embedded in paraffin wax, sectioned at a thickness of 4㎛, and stained with Hematoxyling-eosin for general histological observation and with PAS reaction, Alcian blue pH 2.5 or 1.0, Alcian blue pH 2.5-PAS or 1.0-PAS reaction, Aldehyde fuchsin pH 1.7, and Aldeliyde fuchsin pH 1.7-Alcian Blue pH 2.5 for histochemical finding. The mucous compositions in mucous cells of the gastrointestinal tract examined by their stain reaction were neutral mucin, acidic mucin, sulfomucin, sialomucin, The results obtained were as follows; The folds of the gastrointestinal tract in the hibernating phase, compared with the active phase, shrink and lower. Also, the shrinkage of epithelial cells were observed in the hibenating phase. The surface mucous cells of the stomach in the active phase composed mainly neutral mucin and a little amount of acidic mucin including sialomucin, but in the hibernating phase neutral mucin and sialomucin slightly decreased. The mucous neck cells of the stomach in the active phase constituted mainly neutral mucin, In the hebernating phase the mucous neck cells were composed of neutral mucin and a little amount of acidic mucin contained sialomucin. The mucous cells of the small intestine in the active phase consist of neutral mucin, acidic mucin including sulfomucin and sialomucin but in the hibernating phase sulfomucin and sialomucin slightly decreased.

복수암 Sarcoma 180을 생쥐의 B 임파구 분화에 미치는 Ascorbate의 영향

강영준,노정혜,강사욱,정가진 大韓免疫學會 1993 大韓免疫學會誌 Vol.15 No.-

Ascorbate is one of the important radical scavengers. Its roles in biological system including anti-cancer effects have been broadly studied. Ascorbate recovered the function of B lymphocytes which was suppressed by Sarcoma 180-derived immunosuppressive factor(s). Production of anti-SRBC antidody was increased by the adminisration of ascorbate in the Sarcoma 180 culture supernatant-treated mice. Ascorbate enhanced the suppressed immune function of tumor-bearing hosts. Treatment of 1 mg of ascorbate increased the function of B lymphocytes, however, 10ug of ascorbate treatment decreased. In vitro treatment of ascorbate increased the immunoglobulin production ac-cording to the increasement of ascorbate concentration. These results also imply that ascorbate may be a immunoreeulatory molecule.

Pityrosporum 균속의 항진균제에 대한 연구

방용준,노병의,정병천 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 1997 Journal of biomedical laboratory sciences Vol.3 No.1

Pityrosporum spp.은 1952년 Vanbreuseghem가 전풍환자에서 분리한 Pityrosporum spp.를 round form, elongated form 및 oval form으로 구분하고 이중 round form를 Pityrosporum(P.) orbiculare라 하고 oval form를 P.ovale에 해당된다고 하였다. 현재 Pityrosporum 균속에는 P. orbiculare, P. ovale, P. pachydermatis가 있고, 이중 P. orbiculare, P. ovale는 호지방성으로 배양시 일반적인 진균배지에 올리브 기름을 첨가하여 37℃에 배양하면 효모양의 집락을 형성하며 cholesterol, cholesterol ester가 첨가된 배지와 전풍환자에서는 균사를 볼 수 있다. Pityrosporum spp도 Candida spp.처럼 효모기(yeast phase)는 비병원성이고 균사기 (mycelial phase)에는 병원성이 있으며 균의 분리는 전풍환자에서 뿐만 아니라 건강한 성인에서도 90%이상 배양되는 인체에 정상적으로 존재하는 상재균이기도하다. 이러한 배양 조건 때문에 Pityrosporum 균속의 항진균제에 대한 연구는 드물다. 이에 현재 사용되고 있는 ketoconazole, itraconazole, selenium sulfide, sodium thiosulfate의 MIC검사를 한 결과 ketoconazole은 0.05∼0.8㎍ ml-¹로 itraconazole, selenium sulfite 및 sodium thiosulfate보다 ketoconazole이 MIC가 가장 낮게 나타난다. P. orbiculare의 대한 각 약제의 MIC를 비교해 보면 4종의 약제 전부에서 ketoconazole이 낮았으며, 건강인에서 분리한 균주가 전풍환자에서 분리한 균주보다 MIC50, MIC90에서 모두 낮았다. P. ovale에 대한 경구용 및 국소용 항진균제의 MIC50, MIC90에서도 P. orbiculare보다 현저히 낮은 MIC를 보였다. Meanwhile pityrosporum species as well as Candida species in yeast phase are not pathogenic, Pityrosporum in mycelial phase is pathogenic. Pityrosporum species can be isolated not only from tinea versicolor patients but also from ninety (90) percent of healthy persons. Minimal inhibitory concentration (MIC) of ketoconazole against Pityrosporum spp. was 0.05∼0.8㎍ ml-¹and the MIC of ketoconazole was the lowest. Of itraconazole, selenium sulfide, sodium thiosulfate and ketoconazole had the lowest MIC against P. orbiculare. The P. orbiculare strains isolated from healthy persons were inhibited by lower MIC than those isolated from tinea versicolor patients. P. ovale strains were inhibited by lower MIC at MIC50 and MIC90 of oral and topical antifungal agents than P. orbiculare.

This study was executed in order to gauge the possibility of the strategy of marketing communication, which was for an increase of female consumer' participation in sports. It was conducted among a random sample of 1.346 women over the age of 18 in Pusan area, and its contents of survey was the shape of leisure activity and preferation of mass media, the aspects of their watching TV. 1. The form of leisure activity seemed to be most favoured as spectators.. Meanwhile sports-type leisure activity appeared to be more favoured by people out of work compared to people in work. 2. It was shown in the most people that they got the media of the use of commercial sports institution by their family or friends. 3. It was shown that female magazines was the most favoured among periodical magazines. 4. In daily newspapers, they prefer local one to central one. Meanwhile sports-newspaper was the worst favoured. 5. TV news was the most preferred, that is in case of the married against the unmarried. 6. It was the most shown that sports program was watched during suitable hours. But a few people answered that they hardly watch that. 7. It was shown that cultural program was watched generally during suitable hours, yet the unmarried scarcely watch that. 8. It was the most shown that comedy program was watched during suitable hours. But a few people answered that they hardly watch that. 9. It was the most shown that dramatic series and movie program were occasionally watched by them.

노령의 대퇴 전자간 골절 치료에서 압박고 나사못의 안정성 및 유용성

김종오,노권재,윤여헌,고영도,유재두,정준모,방한천,정재학 대한골절학회 2003 대한골절학회지 Vol.16 No.2

목 적: 노령의 대퇴 전자간 골절에서 압박고 나사못의 안정성에 영향을 주는 인자들간의 상관 관계와 골절 양상에 따른 술후 고관절 기능을 평가 및 분석하였다. 대상 및 방법: 압박고 나사를 이용하여 수술적 치료를 시행한 231명의 환자 중 6개월 이상 추시가 가능하였던 60세 이상 84명의 환자들을 대상으로 했다. 방사선적 계측은 압박고 나사못의 활강 길이 및 내반각, 가압 나사 위치, 정복 상태, 원위 골편의 내측 전위를 측정하였으며 술후 기능은 Clawson의 기능 평가표로 하였고 골절 양상에 따라 방사선 계측과 기능 회복과의 상관 관계를 평가하였다. 결 과: 임상 결과는 불안정 골절에서 양호가 10례, 불량이 23례, 안정 골절에서는 양호 40례, 불량이 11례로 안정 골절에서 임상 결과가 좋았고(p<0.001), 압박고 나사 활강은 10 ㎜ 이상일 때 양호가 4례, 불량이 21례, 10 ㎜ 이하에서 양호가 46례, 불량이 13례로 10 ㎜ 이상 활강시에 술후 결과가 불량했다(p<0.001). 다르 방사선적 계측 요인은 결과에 의미있는 차이를 보이지 않았다. 또한, 불안정 골절 중에서 전위 양상 골절의 경우 10㎜ 이상 활강이 12례, 10㎜ 이하 활강이 8례, 분쇄 양상 골절의 경우는 10㎜ 이상이 11례, 10㎜ 이하가 2례로 분쇄 양상의 불안정 골절에서 10㎜ 이상 활강이 의미있게 많았다 (p<0.001). 결 론: 10㎜ 이상의 지연 나사 활강은 고관절 기능 회복 약화를 유발시킬 수 있으며 불안정 골절 분쇄 양상 골절은 이런 지연 나사의 활강이 과도하게 유발될 수 있으므로 불안정 분쇄 양상 골절에서 압박고 나사의 단독 사용은 재고해 보아야 할 것이다. Purpose: To evaluate the relationship between fracture stability and functional results, and analyze the correlation between stability factors and the outcome in intertrochanteric fracture of the elderly. Materials and Methods: Of the 231 patients, 84 patients with age above 60 were able to follow up for minimum 6 months. We measured the sliding length of the lag screw, varus degree, position of lag screw, reduction status and medialization of distal fragment radiologically. The functional outcome of the treatment was evaluated with the Clawson's result classification and we evaluated the correlation between the radiological results of measurement and the functional recovery depending on the Evans fracture classification. Results: There were good results in 40 cases out of 51 stable fractures, and in 10 cases out of 33 unstable fractures (p<0.001). In case of sliding of lag screw more than 10㎜, good results were obtained in 4 cases, and poor in 21. And in case of sliding less than 10㎜, good results were obtained in 46, and poor in 13. (p<0.001).But there was no relationship between other radiologic factors and clinical results. In unstable type, there were 12 cases with lag screw sliding more than 10㎜ and 10 cases with less than 10㎜. In comminuted type, there were 11 cases with lag screw sliding more than 10㎜ and 2 cases with less than 10㎜(p<0.001). Conclusion: The sliding of lag screw more than 10㎜ may result in poor outcome. As in comminuted unstable pattern, sliding of lag screw might be excessive, the use of compression hip screw alone is not good treatment option.
