안명수,홍용길,최창락,송진언 대한신경외과학회 1984 Journal of Korean neurosurgical society Vol.13 No.2

In 1960, Tskimoto first mentioned the spinal cord lesions caused by compression of posterior longitudinal ligament (OPLL), thereafter, hundreds of cases have been reported. There are, however, some controversial opinions concerning the mechanisms of the formation and development of OPLL and questions why a special ligaments, posterior longitudinal ligaments can be calcified, enlarged and compress the cord. And also, there have been many reports describing various surgical method that could manage OPLL, but the OPLL still has many problems in surgical treatment. Recently, the neurosurgical team at the St. Pauls Hospital, encountered and operated on 7 cases of OPLL at cervical area. After all dignostic tests and examinations were done, the morphological classification, combined other lesions and pathological status were verifed and analyzed during treatment. The different surgical methods were taken case by case. The authors would like to share with you our experiences of the surgical methods, indications of operation the results and the progrosis of treatment in OPLL.

데이터 증강 기반 Saliency U-Net을 이용한 저해상도 객체 검출 방법에 대한 연구

안명수,임혜연,강대성 한국정보기술학회 2023 한국정보기술학회논문지 Vol.21 No.8

Object detection in low-resolution images is often vulnerable to noise and results in performance degradation when relying only on traditional object detection algorithms in industrial applications due to low image quality. In order to solve this problem in this paper, the knowledge distillation-based GAN (Generative Adversarial Networks) algorithm is applied to convert high-resolution image data such as rotation, size, inversion, resolution, etc. and generation. In addition, we study a method of detecting and tracking a specific object using U-Net based on the Saliency mechanism for the generated data. Through comparative analysis experiments with existing detection methods, it was verified that the proposed method provides higher accuracy and robustness in low-resolution images. As for the experimental approach, the performance was evaluated in three open data sets related to industrial detection, and it was confirmed that the mAP was improved by more than 5% compared to the existing method.

오미자 추출물의 항산화 효과

안명수,표영희,장은희 한국조리과학회 1996 한국식품조리과학회지 Vol.12 No.3

국내산 오미자의 용매별 추출물의 항산화력을 검토하기 위해 극성이 다른 5종의 용매를 사용하였고 0.05%, 0.1% 그리고 1.0% 농도로 기질 대두유에 첨가하여 용매별, 농도별에 따른 각각의 결과를 POV와 AV측정치를 통해 비교하였다. 용매 종류에 따른 오미자 추출액의 항산화 효과는 EA > MeOH > EtOH > PE > BtOH 순으로 나타났고 이들의 항산화력은 0.02%의 BHT 보다는 약했으나 0.02%의 α-Toc에 비해서는 월등히 높았다. 또한 첨가농도별 오미자 추출액의 항산화 효과는 모든 시료에서 0.05% 농도가 가장 높았고 그 이상의 농도에서는 그다지 효과가 두드러지지 않거나 오히려 감소하였다. 각 용매별 오미자 추출액을 0.05% 농도로 대두유에 첨가한 뒤 항온저장(60±2℃)과 가열조건(180±2℃)에서 각각의 항산화능을 측정한 결과 두 조건에서 모두 EA와 MtOH, EtOH 추출액의 순으로 항산화력이 높게 나타났으며 특히 가열시에는 BHT의 항산화력보다 높은 것으로 비교 되었다. 나머지 용매, PE와 BtOH 추출물도 대조구에 비해 항산화능이 인정되었으나 가열조건에서 BtOH은 대조구와 뚜렷한 차이점이 발견되지 않았다. 그러나 α-Toc 첨가구에 비해서는 모든 조건에서 용매별 오미자 추출물의 항산화 작용은 훨씬 높게 측정되었다. 따라서 오미자에 함유된 항산화 성분의 검색과 천연 항산 화제로서의 이용 가능성에 대한 지속적인 연구가 진행된다면 오미자의 용매 추출물은 천연 항산화제로 사용될 수 있을 것으로 사료되었다. Antioxidative activities of the extracts from Schizandra Chinesis Baillon (Omija) with various solvent were compared with some commercial antioxidants. AI (antioxidative index; induction period of oil containing extract/induction period of control oil) of Omija extracts from five kinds of solvents (MeOH, EtOH, BtOH, EA, PE) and other antioxidants were shown as following orders: 0.02% BHT > 0.05% EA > 0.05% MeOH > 0.05% EtOH > 0.1% EA > 0.05% PE > 0.05% BuOH >> 0.02% alpha-tocopherol. Antioxidative effects of 0.05% EA and 0.05% MeOH extracts during autoxidation (60±2℃) were higher than those of the other extracts but were not greater than that of 0.02% BHT. However, AI of EA and MeOH, EtOH extracts during thermal oxidation (180±2℃) were greater than that of BHT. The antioxidant effect of alpha-tocopherol showed no apparent difference or a prooxidant effect as compared with result of control.

뇌신경 질환에서 Actigen의 치료 효과

안명수,최창락 대한신경외과학회 1983 Journal of Korean neurosurgical society Vol.12 No.4

20명의 신경학적 이상이 인지되는 환자에서 제단백 혈액 추출물인 Actigen을 1~2주간 주사 치료하였다. 이들 치료 전후의 비교에서 치료 후 임상 증세호전이 뚜렷했고 간접 비교 기능으로 시행한 뇌파, 유발전위 검사 CT촬영 및 CBF 촬영상 비교에서 좋은 치료효과를 통계적으로 인지할 수 있었다. 이런 결과로 Actigen이 뇌대사 장애를 개선 시키고 말초혈류 및 뇌혈류량을 개선시킨다는 사실을 간접 확인할 수 있었다. 이 제제의 주사 치료중 부작용이나 합병증은 발생되지 않았다. 20 patients who were diagnosis neurologic diseases were treated deproteinized extract Actigen for 1-2 weeks. Comparing before and after treatment, clinical state, EEG, MEP, CT Scan and CBF have been improved to postmedicated state. According to above findings, it is indirectly confirmed that Actigen is improve brain metabolism, cerebral blood flow and peripheral blood flow. During medication there are no side effects and complications.

품종별 부추 추출물의 항산화성 및 항균성에 관한 연구

안명수,김현정,서미숙 한국식생활문화학회 2005 韓國食生活文化學會誌 Vol.20 No.2

The antioxidative and antimicrobial activities were carried on the leeks (Allium tuberosun R.) ethanol extracts in order to find out new food functional components. Three species of leeks used in this study were Chinese leek(long type, LL), general leek(medium type, LM), and medicinal leek (short type, LS). Total amounts of polyphenol compounds in LS was shown as the highest (436.60mg%) value. All of ethanol extracts of these leeks were shown to be had good electron donating ability(EDA) and nitrite scavenging activity. Specially, the ethanol extract of LS(LSEx) had the highest EDA 30.47% and nitrite scavenging activity 77.24% and the lowest was LMEx.The antioxidative activities of these ethanol extracts on the corn germ oil were measured by peroxide values(POV) and conjugated diene values (CDV) storaging for 30 days at 60±2?C. The antioxidative activities of these extracts by POV and CDV were determined as following order as LSEx> LLEx> LMEx. The antioxidative activities of all extracts were presented as high tendency by increasing adding amounts (0.02%>0.05%>0.1%). When the antioxidative activities were compared with BHT and a-tocopherol, the degree of the antioxidative activities of these extracts were certified as lower than BHT and higher than a-tocopherol. And also LSEx, LMEx, and LLEx had antimicrobial effects on the several micro organisms, especially the effect on the Pseudomonas aeruginasa was remarkable. While LMEx had shown inhibit effect on most of micro organism used in this study.

Lumbar Disc Syndrome 환자의 Spinal CT 및 SEP의 의의

안명수,이일우,최창락,송진언 대한신경외과학회 1985 Journal of Korean neurosurgical society Vol.14 No.1

The cause of so - called lumbar disc syndrome arc multiple and each cause must be thoroughly and carefully investigated. The proper treatment may not be successful if one of these factors is ignored. Forty patients with lumbar disc syndrome were examined with a third generation CT scanner (Somatom Ⅱ) and SEP for 12 months. The findings of CT scan were characterized according to the criteria suggested by Carrera and Hermanus and all results were analized thoroughly. The aim of this article is to underline the importance of the correlative studies between spinal CT and SEP in relation to lumbar disc syndrome.

STA-MCA Anastomosis의 9예 보고 : 9 cases

안명수,성기원,최창락 대한신경외과학회 1983 Journal of Korean neurosurgical society Vol.12 No.4

Since 1967 the STA-MCA anastomosis has been popular procedure in neurosurgical operation. The neurosurgical teams at St. Paul's Hospital, Catholic Medical College, recently operaten on 8 patients employing 9 times of this technique. The patients were diagnosed as four patients with complete stroke, one with traumatic middle cerebral stenosis, two with moyamoya disease, and one with huge aneurysm at intracavernous portion of ICA. The results were very encouraging of the 8 patients, 7 had favorably improved clinically, and proved by follow-up cerebral angiographies, CT Scanning, EEG or MEP recordings. The remaining one patient had intracerebral and intracerebellar hematoma, two months later after discharge, thus the result was poor. The authors would like to share with you their experiences employing the STA-MCA anastomosis technique, indications the results and the prognosis.
