본 연구는 차량 주변을 지능적으로 감시하는 자동차 주변 감시시스템에 관한 것으로, 자동차의 주행 및 주차 시 속도의 변화나 운전자의 요청에 의해 자동차 주변 지역에 관한 시야를 상황에 따라 달리하여 모니터링 함으로써 운전자가 안전한 주행 및 주차를 수행할 수 있게 하기 위한 것이다. 그러한 목적을 달성하기 위하여 본 연구에서는 차량의 주변부를 감시하기 위하여 차량의 외곽에 설치된 카메라의 각도가 지면으로부터 차량의 상부를 향하는 방향으로 변경될 수 있도록 제어하는 제어부, 카메라의 영상을 입력받아 차량주변의 영상을 생성하는 영상처리모듈, 영상처리모듈에서 생성된 영상을 출력하는 디스플레이를 포함하는 것을 특징으로 하는 지능형 자동차 주변 감시시스템을 제안한다. This study is on a vehicle surroundings monitoring system, which enables a driver to travel and park safely by monitoring vehicle surroundings, depending on the speed of vehicle and driver's control when traveling and parking. To achieve the aforementioned purpose, we propose an intelligent vehicle surroundings monitoring system, which consists of a control part, an image processing module and display module. Hence, the control module controls angle of camera to turn upward from the bottom to monitor vehicle surroundings. The image processing module merges the received images from cameras with the original vehicle image to display the vehicle’s surroundings in real time as if looking down from the sky.

박현숙,이수웅,오근희,박영식 인제대학교 1994 仁濟論叢 Vol.10 No.1

45Ca overlay를 이용한 방법으로 Allomyces macrogynus의 생장과정에서 형성되는 암수배우자 홀씨, 반수체 홀씨, 그리고 이배체 홀씨등의 세가지 홀씨와 팡이실에 존재하는 칼슘이온결합단백질들을 검색하였다. 세가지의 홀씨 각각에서는 모두 5가지 종류의 칼슘이온결합단백질들이 동일하게 관찰되었다. 팡이실에서는 적어도 6개 이상의 칼슘이온결합단백질들이 관찰되었으며, 이중에 3가지는 홀씨에서 관찰된 것과 동일한 것으로 판단된다. Ca2+-dependent phenyl-sepharose를 이용하여 팡이실에서 SDS-PAGE 겔 상에서 19kDa의 분자량을 가지는 칼슘이온결합단백질을 분리하였다. 이 단백질은 등전점이나 열에 대한 안정성, 칼슘이온에 의한 전기영동상에서의 움직임의 변화 등으로 판단하건 데 calmodulin으로 추정된다. 따라서 Allomyces macrogynus의 홀씨와 팡이실에는 calmodulin을 비롯하여 다수의 칼슘이온결합단백질들이 존재하며, 이들 중에는 홀씨, 또는 팡이실에서만 관찰되는 것들도 있었다. Calcium binding proteins(CaBPs) present in 3 different types of zoospores and in mycelium of Allomyces macrogynus were screened by using 45Ca overlay method. Five different kinds of CaBPs were equally observed in gametes, haploid spores, and diploid spores, respectively. Six kinds of CaBPs were observed in fractions of DEAE-cellulose chromatography of mycelial extract. Among them 3 CaBPs were shown to be identical with those detected in zoospore extract. 19-kDa CaBP was isolated from mycelial extract by Ca2+-dependent phenyl-sepharose chromatography. The 19-kDa mCaBP showed calmodulin-like properties as determined by molecular weight, isoelectric point, and Ca2+-dependent mobility shift on SDS-PAGE. It is shown that a variety of CaBPs including calmodulin-like protein are present in zoospores and mycelium of Allomyces macrogynus and some are confined to either.

In this Paper, we are study about a corrlation of EMG Signal and acufuncture stimulation. We use resting EMG signals for observation of physiological change. In experiment, we use No-Goong haul of Sukwaleum- Simpo-kyung and Hap-Gog hyul of Suyangmyong-Daechan gyung for stimulation reference point We had examed in three cases. At the first case, we take EMG signal from the same kyung-rak route of No-Goong and Hap-Gog by same stimulation. The second case, EMG signal take from corresponding spot of the another hands palm by Hap-Gog haul stimulation. The last case, EMG signal take from corresponding spot of the foot's sole by Hap-Gog hyul stimulation. As the result of experiment, Hap-Gog huyl stimulation has more power density signals than that of No-Goong hyul at the first case, and we could observe variation of 0㎐ component only at the second and third case.

김수진,박은지,안승원,김웅,김미운,임현술 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.5

Background: Propofol is a good induction agent. but it has a disadvantage of pain on intravenous injection. Pretreatment of metoclopramide or lidocaine have been reported to reduce pain on injection. thus, we have evaluated the quantity and quality of anagesic effect of metoclopramide and lidocaine. We observed differences in quality of pain according to venous cannula sizes and intravenous injection sites as well as nausea and vomiting in the postoperative state. Methods: Eighty patients scheduled for an elective operation by general anesthesia were chosen according to ASA (Ⅰ or Ⅱ) and divided into four groups randomly. Each group was injected through venous cannulas with normal saline (control group), metoclopramide 5 mg (group 1), netoclopramide 10 mg (group 2), or 2% lidocaine 40 mg (group 3) respectively. Then, propofol was injected of a 2 mg/kg dose with 0.5 ml/sex to all groups and we asked questions about injection pain after 10 seconds. Results: Pain relief was shown in all groups compared with the control. but metoclopramide 10 mg and lidocaine 40 mg pretreatment groups showed significant pain reief. Pain was relieved significantly when the drug was injected in the antecubital area. Postoperative nausea and vomiting were not observed. Conclusions: Metoclopramide 10 mg or lidocaine 40 mg pretreatment to induction by propofol revealed a good analgesic effect for propofol injection pain. (Korean J Anesthesiol 2002; 43: 558~565)

쌀, 조 수수, 및 콩의 식이가 흰쥐의 성장 및 혈액 성상에 미치는 영향을 조사하기 위하여, 평균체중 180g의 Sprague-Dawley계 rat(♂) 각 5마리씩을 대조군(T_(0)), 쌀(T_(1)), 조(T_(2)), 수수(T_(3)), 콩(T_(4))급이군등 5개군으로 나누어 실온에서 6주간 사육하면서 사료섭취량, 급수량, 증체량과 6주후의 혈액상의 변화틀 조사하였다. 사료 섭취량은 대조군이 각 처리 실험군보다 높았으며 물의 급수량도 동일한 결과이었으며 그 순위는 쌀, 조, 콩, 수수 순으로 감소하였으며, 각 처리군의 증체량은 대조군 보다 낮았으며, 특히 수수는 초기보다 감소하였고, 각 처리군의 사료효율은 대조군보다 낮았으며 특히 수수처리군이 타 처리군보다 낮았다. 연액성상의 변희는 대조군에서는 큰 변화가 없으나 수수군에서 BUN, HOT지 다른군보다 높았으며 쌀의 처리군은 creatinine치가 높았고 조에서는 혈당치가 낮았으며, 콩에서는 LDH는 높았고, HGB, HCT, PI.T, RBC가 낮았고, 특히 콩 수수에서는 혈액상의 변화가 가장 컸으며 다른 실험군과 비교하였을 때 통계적인 유의성이 인정되었다. This study was conducted to investigate the effects of rice, millet, sorghum and soybean diet on the growth rate, daily intake feed ratio and change in hematology of male rats. The experimental male rats of 180g average weight were fed on control (T_(0)), rice (T_(1)), millet (T_(2)), sorghum (T_(3)) and soybean diet (T_(4)) for 6 weeks. The amount of daily feed and water intake supply in each diet group is higher than that of control group to as shown in the following order: rice, millet, soybean, sorghum. The growth ratio of each diet group is lower than that of control group. Especially, sorghum made each diet group reduce the weight even more than the initial weight. Control group is lower than each diet group in regard to the effective ratio of feed. Especially, the sorghum group is lower than other groups. Control group remained same in the change of hematology, however, sorghum group is higher than other groups for BUN, HCT. Rice group is higher in creatinine and millet group is lower in glucose content of serum than any other groups. Soybean group is higher in LDH but lower in HGB, HCT, PLT, RBC than control group. Especially, the soybean and sorghum groups showed a big change in hematology and had the statistic significance in comparison to other groups.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

In Korea, waste-oyster shells discharged from oyster culture industry cause a serious ocean environmental pollution. There is a need for developing low cost, easily and abundantly available adsorbent. So, waste-oyster shells could be recycled as a nitrogen adsorbent because of those large specific surface area. And natural zeolites are known as a good adsorbent of NH^(4+) ion. Thus, the objective of this research is to observe removal trends of nitrogen from tannery wastewater with waste-oyster shells and natural zeolite using continuous fixed bed reactors. 피혁폐수는 다양한 유기물을 함유하고 있을 뿐만 아니라, 가공공정상 질소화합물이 많이 사용되기 때문에 고농도의 유기질소 및 암모니아성 질소가 함유되어 있어 적절한 처리 없이 주변수계로 방류될 경우 자연정화작용을 방해하여 수계의 부영양화가 진행되어 남조 및 적조의 원인이 되고있다. 일반적으로 수역의 제한요인은 대개의 수역에서 질소 제한, 인 제한,질소·인 동시제한 중 어느 하나이며 계절이나 시대 추이에 따라 변화하므로 부영양화 대책으로 질소·인 모두 제거해야 한다. 최근에 천연제올라이트가 암모니아성 질소제거에 효과적인 것으로 보고되면서 이에 대한 연구가 많이 수행되었다. 암모니아를 포함하는 폐수를 침전 처리한 다음 2차 처리 공정에서 주로 활성탄 및 이온 교환수지 충전탑이 이용되고 있다. 이 중에서 활성탄 홉착은 간편성, 확실성 등으로 아주 효과적인 방법으로 각광받고 있지만 고가라는 단점을 가지고 있다. 이에 비해 상대적으로 저가인 천연 제올라이트에 의한 암모니아 제거공청은 다른 공정에 비하여 제거속도가 크고 수온의 변화에 영향이 적으며, 고농도 뿐만 아니라 저농도의 암모니아에 대해서도 안정적인 처리효율을 보이는 것으로 알려져 있다.또한 공정자체가 간단하며 기존의 정수 및 폐수 처리시설에 적용하기가 용이하며, 처리후 발생하는 물리, 화학, 생물학적 부작용이 거의 없는 것으로 알려져 있다. 한편, 국내 해안 양식업 중에 비중이 높은 굴양식업에서 부산물로 다량 발생하고 있는 폐굴껍질은 28만톤에 달하고 있고 그 중에 약 10%만이 종패 부착용(2만5천톤), 비료(2천톤)로 가공처리 되고 있을뿐 해양수산 폐기물인 굴 껍질의 처리방법과 자원으로 재활용 하기 위한 연구가 필요한 실정이다.
