주차장에서 일어날 수 있는 비매너 주차로 인한 충돌을 사전에 예방하기 위한 단속시스템이다. 주차장에서 일어날 수 있는 장애인, 전기차 전용 주차구역에 일반차량 주차, 2개 차선을 물고 주차하는 차량이 있다. 위와 같은 차량을 딥러닝 객체인식 기능을 통해 비매너 주차를 감지하여 알려준다. 비매너 주차 상황이 찍힌 사진이나 영상을 학습데이터로 사용하여 상황을 인식할 수 있도록 학습데이터를 제작하고 그 상황을 인식하여 비매너 주차 유무를 판단한다. 주차장의 환경을 좀 더 쾌적하게 함으로써 주차장 이용자간 충돌을 줄이는데 목적이 있다. It is a enforcement system to prevent collisions caused by unmanageable parking that may occur in parking lots. There are handicapped people who can get up in parking lots, general vehicles parked in electric vehicle parking areas, and vehicles parked in two lanes. The vehicle above is detected and notified through the deep learning object recognition function. By using a picture or video of an unmanageable parking situation as learning data, the learning data is produced so that the situation can be recognized, and the situation is recognized to determine the presence or absence of unmanageable parking. The purpose is to reduce collisions between parking lot users by making the environment of the parking lot more comfortable.

TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.

The aim of this article is to improve human health and that of companion animals by improving the diagnosis and control of parasitic diseases. This is achieved by research into parasites of veterinary significance including zoonoses and the use of comparative systems to increase our understanding of some human parasitic diseases. We should promotes learning and teaching through knowledge and operates a diagnostic unit that offers a service to pet owner for indigenous and exotic parasitic diseases of companion animals. We must diagnose and treat them early. Zoonotic parasites are very important because many of animal parasites are zoonoses and give pain and death to human. Parasites are divided Protozoa, Helminthes and Arthropods. There are many protozoa, about 65,000 species. Arthropods are the vector of another diseases, such as virus, bacteria, protozoa and nematodes. Helminthes are composed of Trematoda, Cestoda, Nematoda and Acanthocephala. The target of Veterinary Parasitology is to recognize the characteristics of these parasites and subsequently diagnose, treat and control them. This article is intended to familiarize you with the essential facts and concepts of companion animal parasitology. Emphasis is placed on fecal sample techniques (comparison of fecal examination techniques; frequently found artifacts in fecal smears; direct Smear; zinc sulfate flotation; etc.) We recommend that the study be done to more references on animal parasites.

Event Mean Concentrations (EMCs) and First Flush Characteristics of Runoff from a Public Park in Korea

Jung, Jae-Woon,Park, Ha-Na,Yoon, Kwang-Sik,Choi, Dong-Ho,Lim, Byung-Jin The Korean Society for Applied Biological Chemistr 2013 Applied Biological Chemistry (Appl Biol Chem) Vol.56 No.6

Characteristics of non-point source (NPS) pollution runoff from a public park in Gwangju, Korea were investigated. Results exhibited the highest pollutant concentrations at the start of the rainfall events due to their build-up and wash off processes. The average event mean concentrations (EMCs) were 27.8, 7.2, 56.3, 7.5, and 0.84 mg/L (range: 4.2-54.8 mg/L) for COD, (0.5-20.8 mg/L) for TOC, (22.3-138.4) for SS, (1.4-18.5 mg/L) for T-N, and (0.17-2.02 mg/L) for T-P, respectively. The study site presented a strong first flush effect for most rainfall events. However, no first flush effect was observed in rainfall events with small rainfall factors (e.g. intensity, amount, and runoff depth). On the other hand, the ratios of total pollution loads discharged by the first 20% of runoff volume were 32% for COD, 34% for TOC, 36% for SS, 42% for T-N, and 50% for T-P. Especially, $MFF_{20}$ (mass first flush) values of T-N and T-P were larger than those of other pollutants (COD, TOC, SS), indicating that T-N and T-P are easily transported by stormwater runoff from the public park. First flush management of T-N and T-P, therefore, is required for efficient water quality management of the public park.

박명식,최병완,배현경,박종혁 대한골절학회 2003 대한골절학회지 Vol.16 No.2

목 적: 최근 빈도가 증가하고 골절양상도 복잡해지는 인공관절 수술 후 발생한 대퇴 골절의 발생 빈도와 금속판을 이용한 치료 시의 문제점을 문헌 고찰과 함께 보고하고자 한다. 대상 및 방법: 1985년부터 1998년까지 시행된 1,275 (1,188 일차 치환, 97 재치환술)례의 고관절 치환술 시행 환자 중 52명에서 발생한 52ㄹㅖ의 대퇴부 골절을 대상으로 조사하였다. 이를 안정성 여부와 스템 끝 주위의 골절 위치에 따라서 근위부 (Ⅰ), 중심부 (스템 주위) (Ⅱ), 언위부(Ⅲ)로 구분하였고 이를 다시 비전위성 (A), 전위성 (B), 불안정성 삽입물 (C)으로 세부나였다. 치료의 방법으로 삽입물이 안정성을 가진 근위부 골절 (제 1형)에서는 부목 고정이나 환상 강선 고정을 시행하였으며, 스템 끝 (제 2형)이나 원위부 (제 3형) 골절에서는 금속판과 나사못 등을 사용하고 대퇴골 과상부인 슬관절 주변의 골절인 경우 외고정 장치 장착을 하였다. 금속판 고정을 한 경우는 골이식술을 시도하였다. 결 과: 인공관절 치환 후 발생한 골절의 빈도는 4.1%이었고, 이 중 술 중 골절은 1.5%, 술 후 골절은 2.6%이었다. 골절의 평균 유합기간은 3.1개월이었다. 금속판을 이용하여 치료한 경우 2례의 불유합과 3례의 재골절 중 1례는 골절 유합 후 보행 도중 낙상에 의하여, 1례는 골절부 유합 후 금속판 제거 후 발생하였으며, 1례는 체중 부하 도중 발생한 골절이었다. 제 Ⅲ형 골절의 경우 전례에서 스템의 이완 소견은 볼 수 없었다. 결 론: 저자들은 인공고관절 치환술 후 발생한 대퇴골 골절 치료에서 금속판 내고정 후 5례의 비교적 많은 합병증을 경험하였다. 이 중 2례는 부적절한 짧은 금속판의 선택과 조기 보행, 나머지 3례는 금속판 및 나사못과 관련된 골절로서 스트레스가 집중되는 부위인 대퇴 스템 원위단이나 금속판의 근위부는 재골절의 위험이 있으므로 골절의 치료에 있어서 골이식이나 긴 금속판 사용, 골유합시까지 외부충격에 보호 등으로 재골절의 위험 빈도를 해결해야 한다. Purpose: The purpose was to evaluate the postoperative periprosthetic femur fracture of hip arthroplasty and relative problems of management using plate fixation. Material and Method: We reviewed 37 cases of femoral fractures out of 1,270 (1,183 primary hips and 97 revision hips) hips which received hip arthroplasty during the observation period(1985~1998). We classified them according to the stability and the location of the fractures related to the stem tip: Proximal (Ⅰ), middle (around stem)(Ⅱ) and distal(Ⅲ). Then we subclassified the fractures as cortical perforation or a fissure, undisplaced (A), displaced(B) and unstable prosthesis (C). we managed periprosthetic fracture with splint applied or cerclage proximal fracture (type Ⅰ), plate fixation and bone grafts in the step tip(type Ⅱ) or distal fracture (type Ⅲ). Un unstable fractures, we revised them with long fluted stems. Result: The average union time is 3.1 months (range, 2~6.2 months). After management of fracture with plate showed 5 complications, two nonunion and three refractures. The causes of nonunion are weight bearing and a too short plate. The causes of refracture are screw fixation and empty hole just distal to stem tip. The other caused by the roles of stress riser in proximal screw of blade plate in management of supracondylar fracture. Conclusion: We recommend the use of cerclage band system of fixed in a more proximal site in long plate and bone graft. In unstable prosthesis, we had taken a best results after revised with distal fluted stem, in which we don't need further distal stability like a additional cerclage or locking screw and additional bone graft.

박성규,전진우,기신영,유병우,김홍수,백승호,원종호,홍대식,박희숙 순천향의학연구소 1995 Journal of Soonchunhyang Medical Science Vol.1 No.1

Clinical effects of rhG-CSF were investigated in 17 patients receiving chemotherapy for non-Hodgkin's lymphoma. Patients were given G-CSF 2㎍/㎏/day after 2nd cycle chemotherapy for least 14 consecutive days, and clinical and laboratory results were compared to results of the first cycle. Treatment with G-CSF resulted in increase of mean WBC count(952.9±152.2㎜³vs 1882.4±350.4/㎜³) and neutrophil count(212.9±53.0/㎜³vs 841.5±238.0/㎜³), reduced the duration of leukocytopenic days(12.4±1.3 days vs 5.5±1.0 days, WBC count less than 4000/㎜³) and neutropenic days(4.5±0.9 days vs 2.3±0.7 days, neutrophil count less than 500/㎜³), and reduced the duration of neutropenic fever(5.8±1.1 days vs 0.9±0.5 days). The side effects of G-CSF were not so significant. These results demonstrated that G-CSF is safe and useful for the treatment of neutropenia induced by anticancer chemotherapy of non-Hodgkin's lymphoma and reducing the incidence of febrile periods and duration of antibiotic administration.

배경 : MRSA, VRE, VRSA같은 다제 내성 그람 양성균의 등장에 따라 glycopeptide를 대체할 새로운 항생제의 개발이 필요하게 되었고 결과적으로 새로운 항생제인 linezolid라는 항생제가 개발되었다. Linezolid는 이전의 항생제와는 다른 새로운 계열의 oxazolidinone으로 경구 이용률이 우수하다. 원내 및 원외감염의 중요한 원인균이 되고 있는 MRSA, VRE에 대한 적절한 경구용 항균제가 없는 국내에서 폐렴 및 피부 연조직 감염에서 경구용으로 사용해 볼 수 있는 약제이다. 본 연구에서는 고대 구로 병원에서 분리된 MRSA, VRE 등을 대상으로 다른 여러 항균제와 비교한 linezolid의 시험관내 항균력을 조사하고자 하였다. 재료 및 방법 : 연구대상은 1998년 1월부터 2000년 12월까지 본원에서 입원 및 외래를 통하여 피부 연조직 감염증 및 호흡기 감염증, 요로감염증으로 진단된 환자들의 가검물로부터 분리된 MRSA 60균주, VRE 43균주, PRSP 25균주를 액체배지 또는 한천배지 희석법을 통하여 linezolid 및 기타 항균제에 대한 최소발육억제농도를 구하였다. 결과 : 실험에 사용한 S. aureus는 모두 MRSA였고 이들은 linezolid에 대해 MIC_(90) 2㎍/㎖(MIC 범위 1-2㎍/㎖), Enterococcus spp는 모두 VRE로 linezolid의 MIC_(90)은 2㎍/㎖로 MIC 범위는 1-4㎍/㎖였다. 한 개의 균주에서 MIC 4㎍/㎖로 중등도 감수성을 보였으나 MIC breakpoint가 (8㎍/㎖인 내성균주는 없고 모두 감수성을 보였다. S. pneumoniae의 경우 penicillin 내성이었고, linezolid MIC_(90) 1㎍/㎖ (MIC 범위 0.5-1㎍/㎖)로 전부 감수성을 보였다. 결론 : Linezolid는 MRSA를 위시한 VRE, PRSP 등의 다제 내성 그람 양성균에 대하여 우수한 시험관내 항균력을 보임을 알 수 있었다. Background : The emergence of multi-drug resistant Gram-positive cocci, such as MRSA, VRE, and VRSA, necessitated to develop new antibiotics, which could replace the glycopeptide. As a result, a new antibiotics named linezolid was developed. Linezolid is different line of oxazolidinones with a good oral bioavailability, compared to other antibiotics. Since appropriate oral antibiotics are not presently available for MRSA, which is a major cause of nosocomial and community acquired infections, the introduction of linezolid will have favorable effect on treatment of infections such as pneumonia or skin infections. In this study, we investigated the antibiotic effect of linezolid on MRSA and VRE isolated from patients who were treated in Korea University Guro Hospital. Material and Methods : By using broth microdilution and agar dilution method we measured minimum inhibitory concentration (MIC) with sixty S. aureus, forty three Enterococcus spp., and twenty five S. pneumoniae isolates from patients who were diagnosed as skin, soft tissue, respiratory, and urinary infections in Korea University Guro Hospital from January, 1998 to December, 2002. Results : All of S. aureus used in this study were MRSA, and MIG_(90) of linezolid was below 2 ㎍/㎖ (MIC ranged between 1-2 ㎍/㎖). All of Enterococcus spp. were VRE, and had MIG_(90) of 2 ㎍/㎖ (MIC ranged between 1 to 4 ㎍/㎖). One of the VRE showed intermediate susceptibility with MIC of 4 ㎍/㎖. However, none was resistant with MIC breakpoint above 8 ㎍/㎖. All of S. pneumoniae were resistant to penicillin, but they were susceptible to linezolid with MICao of 1 ㎍/㎖(MIC range 0.5-1㎍/㎖). Conclusion : In conclusions, linezolid has an excellent in vitro antibiotic effect on multi-drug resistant Gram-positive cocci, such as MRSA, PRSP, and VRE.

The purpose of this study was to evaluate the effect of immediate or delayed composite resin filling on dentinal microtensile bond strength (μTBS) after applied the adhesive. The coronal dentin of human third molars was exposed. Single-Bond or One-Step was applied on the dentin surfaces, and composite resin were constructed immediately (group 1) or 5 min., 10 min., 15 min., 20 min. and 30 min. (groups 2-6) after an adhesive was applied. The specimens were sectioned and made bar-shaped. Each surface area of them was about l ㎟. The RBS test was performed by EZ test. The results were analysed by One-way ANOVA and Tukey's test at 95 % significance level. The results suggested that the μTBS of Single-Bond to dentin was decreased when the composite resin was constructed 20 min. and 30 min. after Single-Bond was applied. But the μTBS of One-Step was not affected by delayed composite resin filling.

In rare occasions in which aneurysmal neck clipping is nearly impossible, coating is employed. During the period from 1985 to 1992, 312 patients with aneurysm underwent surgery ; aneurysmal neck clipping were performed in 284 cases while coating only in 28. The reasons that coating was required were ; wide and broad neck in 13, perforators arising from the neck in 4, neck tearing during dissection in 3, very friable neck in 2, severe adhesion with surrounding structures in 3, and small aneurysm without enough room for clipping in 3. In twenty-three cases, cotton wisp and bioglue were used as coating materials. In another five cases, the aneurysmal wall was reinforced using Surgicel or Gelfoam. Patients were followed for 24 months on average of all the patients. Four had last contact Six died(4 due to rebleeding and 2 due to pneumonia). Fourteen were good and 4 were moderately disabled. There were no rebleeding incidences during first three months' follow-up after coating. We thus concluded that coating an aneurysm offers some protection from rebleeding, particularly when the rebleeding risk period is over.
