백진웅,김광호,Baek Jin-Woong,Kim Kwang-Ho 대한예방한의학회 2001 대한예방한의학회지 Vol.5 No.2

It is thought that Kim Hong-kyeong followed the existing theory of Meridian(經絡) and supplemented his unique perspectives in interpreting it. And he tried to relate Meridian with hygiene of mind. I took up with the research on the assumption that the review of Kim's method can present new perspectives to the study of relationship between Meridian and hygiene of mind. The results of my study are as follows: 1. Kim followed common theory of Meridian and then added his unique perspectives to it. His method of interpretation has one characteristic. By introducing Idealism(唯心論), he understood 'Meridian' as the path of the mind and the emotion. Especially I think his hypothesis that acupuncture can be widely used in mental diseases as well as body related diseases and its applications to treatment are very valuable. 2. Meridian and hygiene of mind are close together. I think Kim's unique trial is something new in studying relationship between Meridian and hygiene of mind but requires more research on it.

한승백,전영진,백광제,김준식,김정택,김광호,선경 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.4

Aortic transection or interruption is a rare condition which developed after an acute deceleration injury. Its occurrence depends on the location and direction of the force applied and is usually from motor vehicle accident or falling down. The exact incidence of aortic transection in trauma is not known but, when develops, only about 10-15% of the victims can survive and be transported to the hospital. Even in the survivors, majority of them will be fatal within a few days if a prompt diagnosis and surgical treatments are not made. Aggressive diagnostic work-up is recommended for the patients with high suspicious index, which would salvage the victims with this fatal condition. We report the experience of two cases of aortic transection or interruption following motor vehicle accidents.

김광백 新羅大學校 2003 論文集 Vol.52 No.-

This paper proposes a method which recognizes student's identification card by using image processing and recognition technology and can manage student information on the web. The presented scheme sets up an average brightness as a threshold, based on the most bright pixel and the least bright one for the source image of the ID card. It is convert to binary image, applies a horizontal histogram, and extracts school number through its location. And, it removes the noise of the school number region, each number is extracted using vertical histogram and normalized. Each recognition of school number is done by the ARTI algorithm. Experiment results show that the proposed scheme can efficiently extract the region of school number and recognize its letter. So, it can effectively manage student information through a database of the recognized characters.

새로운 PCR 클로닝 벡터의 개발

김윤일,백광희,윤재승 경희대학교 산학협력기술연구원 1996 산학협력기술연구논문집 Vol.2 No.-

PCR (Polymerase Chain Reaction) is a powerful technique for amplifying specific DNA region of interest. The PCR was used first only in the field of molecular biology, but nowadays it is widely used in the various fields such as diagnosis of genetic disorders, identification of forensic samples, and classification of organisms. However, Taq(Thermus aquaticus)DNA polymerase used in PCR has been reported to add a single nontemplate-directed A residue to the 3' ends of amplified KNA, giving rise to the difficulties in the cloning of amplified DNA. Considering the wide applications of the PCR, the development of the efficient cloning vector for PCR-amplified DNA would be very helpful for various purposes, we have designed the PCR cloning vector using the nucleotide sequence recognized by restriction endonuclease Xcm I. The double incorporation of Xcm I recognition sites in the pUC 19 and m13 DNA can make compatible ends carrying T residue and be easily ligated to PCR products.

김성조,백승화,김운성,문광현 한국식품영양학회 1998 韓國食品營養學會誌 Vol.11 No.6

농산물의 갈무리시 발생되는 건조한 마늘, 쪽파 및 대파 뿌리 분말을 흡착제로 이용하여 수용액 중 이온 상태로 존재하는 Ni과 Pb의 흡착력을 시료의 입자별, 중금속의 농도별, 용액의 온도별, pH별로 분석하였다. 중금속 이온들은 흡착제의 입자크기가 작을수록 흡착률이 높았고, 그중 마늘뿌리가 Pb에 대해 높은 흡착력을 나타냈다. 수용액중 중금속 농도가 높을수록 중금속들이 흡착되는 양이 증가하였고, 흡착률은 흡착제와 중금속의 종류에 따라 차이가 있었다. 온도의 증가는 쪽파와 대파에서 Ni과 Pb가 감소되었다. 알칼리 조건에서 비교적 흡착이 잘 되는 중금속은 Ni이며, 중성과 산성조건에서는 Pb의 흡착량이 높았다. A batch experiment was conducted to evaluate the removal capacity of welsh onion(Allium fistulosum L.), shallot(Allium ascalonicum L.), garlic(Allium sativum L.) roots as an adsorbent for Ni and Pb in aqueous solution. One gram of the dried Allium root powder was reacted in 100ml of solution containing 10㎎ of each heavy metal and effects of metal concentration, pH, temperature, and size of adsorbent on the removal efficiency were evaluated. The results were as follows : The amount of adsorption of heavy metal ions were higher with the smaller particles size of adsorbent. Garlic root was high adsorption capacity of Pb, especially. The higher concentration of heavy metal solution was, the more amount of adsorption of heavy metals was. The adsorption ratio was differed from a kind of heavy metal. As the temperature increased, the amount of adsorption of Ni and Pb by shallot and welsh onion were decreased. The amount of adsorption of Ni was high under alkali conditions but the amount of adsorption of Pb was high under neutral and acidity condition.

대구지역의 대기오염도 특성평가(I) : 지역별 및 계절별 농도변동을 중심으로 Locational and Seasonal variations

백성옥,최진수,황승만,김광은 嶺南大學校 環境問題硏究所 1996 環境硏究 Vol.15 No.2

본 연구는 대구지방환경관리청과 유관기관 등에서 과거 7년간(1988~1994년) 측정한 대기질 관련자료중 아황산가스, 분진, 일산화탄소, 질소산화물 및 오존을 대상으로 통계분석하여 각기 배출강도가 다른 지역별 농도분포 특성을 평가하였고 대구지역의 전반적인 대기질 변화추이를 파악하였다. 그 결과 각 지점별 아황산가스의 농도는 전형적인 동고하저형을 나타내었으며, 도시가스공급과 황함량규제등 연료변환 정책의 효과로 인해 점차적으로 감소하고 있는 추세를 보이고 있다. 부유분진은 결측치가 많아 장기적인 농도변화추이를 판단하기는 어려웠으나 아황산가스와 같이 큰 계절적인 변동은 보이지 않았다. 질소산화물의 전반적인 농도분포는 장기 환경기준치 50ppb를 초과하지 않는 수준이었으나 최근엔 이동배출원의 영향이 가중되어 그 농도가 꾸준히 증가하는 추세인 반면 동고하저형의 계절적인 변동을 나타내는 일산화탄소는 가정용 무연탄 사용량의 감소로 대기중 일산화탄소의 농도는 점점 감소하고 있는 추세이다. 오존은 전반적으로 일사량이 많은 하절기에 농도가 높았고 동절기에는 농도가 낮은 경향을 보였다. 한편 주요 대기오염물질의 장·단기 기준달성도를 비교분석한 결과 대구지역의 대기오염물질중 아황산가스의 고농도 발생빈도는 공업지역에 집중되어 있었으며 질소산화물과 일산화탄소는 아직은 장·단기 환경기준을 초과하지 않는 수준으로 나타났고, 분진과 오존의 경우는 공업지역 뿐만 아니라 전지역에서 그 발생빈도가 유사하게 나타났다. In this study, characteristics and distributional patterns of the concentrations of air pollutants in Taegu area were evaluated using a data-base established from the ambient air quality monitoring stations for the period of 1989 to 1994. The result of this study demonstrated that in each sampling site, the SO_2 concentrations were much higher in winter than those in summer. However, a decreasing tendency was clearly shown in the annual variation of SO_2 concentrations, largely due to the use of LPG instead of anthracite coal for local heating systems and to the fuel policy of using lower sulfur content fuel in industrial sectors. Unlike SO_2, there was no distinct seasonal variation in the concentrations of suspended particulate matter. Concentrations of NO_x were found to be generally lower than the long term ambient air quality standard (50 ppb). The NO_x concentration has been gradually increased, reflecting the rapidly increased number of vehicles In this area, while the CO levels In ambient air were declind because of the reduced use of coal for domestic purposes. The Ozone concentrations in Taegu area exhibited that there has been already photochemical smog phenomena during the summer season when the insolation is strong.

김희정,백승호,이우철,박한수,배광식 大韓齒科保存學會 2004 Restorative Dentistry & Endodontics Vol.29 No.6

The properties of ideal root canal sealers include the ability of sealing the total root canal system and no toxic effects to periradicular tissues. Cytotoxicity test using cell culture is a common screening method for evaluation of the biocompatibility of root canal sealers. The purpose of this study was to investigate the cytotoxic effect of newly developed resin-based sealer (Adseal 1, 2, and 3) comparing with those commercial resin-based sealers (AH26 and AH Plus), ZOE-based sealers (Tubliseal EWT, Pulp Canal Sealer EWT) and calcium hydroxide based sealer (Sealapex). An indirect contact test of cytotoxicity by agar diffusion was performed according to the international standard ISO 10993-5. L929 fibroblast cells were incubated at 37℃ in humidified 5% CO₂-containing air atmosphere. The freshly mixed test materials were inserted into glass rings of internal diameter 5 ㎜ and height 5 ㎜ placed on the agar. After the 24 hrs incubation period, the decolorization zones around the test materials were assessed using an inverted microscope with a calibrated screen. A Decolorization Index was determined for each specimen. Adseal 1, 2, and 3 did not exert any cytotoxic effects, whereas AH26, AH Plus, Tubliseal EWT, Pulp Canal Sealer EWT, and Sealapex produced mild cytotoxicity.
