        H. S. KIM, H. J. YOON, J. S. RYU, T. S. KIM. The Three Dimensional Analysis of the Upper Body's Segments of the Elderly during Walking. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 1-15, 2004. The purpose of this study was to investigate the kinematic variables of the upper part of the body for 8 elderly men during walking. For this study, kinematic data were collected using a six-camera (240Hz) Qualisys ProReflex system. The room coordinate system was right-handed and fixed in space, with righted orthogonal segment coordinate systems defined for the head, trunk, and pelvis. Based on a rigid body model, reflective marker triads were attached on the 3 segments. Three-dimensional Cartesian coordinates for each marker were determined at the time of recording using a nonlinear transformation(NLT) technique with ProReflex software (Qualisys, Inc.). Coordinate data were low-pass filtered using a fourth-order Butterworth with cutoff frequency of 6Hz. Three-dimensional angles of the head, trunk, and pelvis segment were determined using a Cardan method. On the basis of each segment angle, angle-angle plot used to estimated the movement coordinations between segments. The conclusions were as follows; (1) During the support phase of walking, the elderly people generally kept their head the flexional and abductional posture. Particularly, the elderly displayed little internal/external rotation. (2) The elderly people showed extensional and external rotation postures in the trunk movement. Particularly, It showed the change from adduction into abduction at the heel contact event of the stance phase. (3) The elderly people showed almost same pelvis movement from the flexion into extension, from the abduction into adduction, and from internal rotation into external rotation at the mid stance and toe off of the stance phase.

        PCR을 이용한 식품 내 Salmonella 균주의 신속 검출방법

        정상훈,김묘영,김현중,김태운,유상렬,김해영 한국응용생명화학회 2003 Applied Biological Chemistry (Appl Biol Chem) Vol.46 No.3

        여러 종류의 식품에서 Salmonella 균주를 손쉽고 빠르게 검출하기 위하여, Salmonella 장독소 유전자(s수)를 기초로 제작한 primer (STN1, STN2)를 이용하여 PCR을 수행한 결과 617 bp의 특이적인 DNA 단편을 얻을 수 있었다. PCR 민감도는 순수 배양한 균체에서 추출한 template DNA는 1 pg까지 검출이 가능하였고, 직접 균체를 template로 이용한 경우에는 10² cells까지 검출이 가능하였다. Salmonella typhimurium을 인위적으로 접종시킨 식품에서는 식품 1g당 10³~10⁴cells까지 검출할 수 있었다. 이러한 결과는 PCR을 이용하여 Salmonella에 오염된 식품에서 이들 균주를 간편하고 신속하게 검출할 수 있을 것이다. This study was carried out to investigate the simple and rapid detection of Salmonella species in different kinds of food using PCR method. The specific primer sets (STN1 and STN2) was designed and utilized to amplify a 617 bp DNA fragment from Salmonella species. The sensitivity of PCR was 1 pg of purified template DNA or 10² cells from pure culture. The detection limit of Salmonella typhimurium on agarose gel electrophoresis was 10³~10⁴cells/g in the artificially contaminated food samples. These results suggested that this simple method could be applied to industrial fields for detection of Salmonella species in food.

        저자들은 척수압박으로 하지마비를 보인 환자에서 수술 후에 급성 백혈병에 동반된 과립구성 육종으로 진단된 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma(GS) is an uncommon tumor composed of immature cells of the granulocytic series. Most case of GS occur in the course of acute leukemia and the blast crisis of chronic leukemia, Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disoders. GS has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia(AML) and the incidence of GS is reported to be higher in patients with t(8;21). GS occurs relatively commonly in africa and has been reported to affect 10-25% of black children presenting with AML. This is very rare case of granulocytic sarcoma with AML(FAB M5) presented with spinal cord compression which was supported by decompression laminectomy.

        우리나라 사람면역결핍바이러스(Human Immunodeficiency Virus) 감염환자에서 발병한 악성종양

        최평균,송진수,조재현,김성한,박경화,방지환,박완범,김홍빈,김동완,김태유,허대석,오명돈,김남중,최강원 대한감염학회 2006 감염과 화학요법 Vol.38 No.6

        Background : Since highly active antiretroviral therapy has lengthened the life span of individuals infected with human immunodeficiency virus (HIV), the importance of malignancy associated with HIV has been increased. The relative frequencies of malignancies in HIV infected patients may vary in different race and region. The aim of this study is to determine the prevalence and characteristics of malignancies in patients with HIV infection in South Korea. Materials and Methods : To identify HIV patients with malignancy, we reviewed the electronic database of pathological reports for all HIV-infected patients seen from January 1986 to December 2005 at the Seoul National University Hospital. We retrospectively reviewed the medical records of them. Results : Among 850 patients infected with HIV, 33 episodes of malignant diseases were diagnosed in 32 patients (3.76%). Thirty were males, and median age was 46 years (range 29-70). At the time of the diagnosis of malignancy, median CD4^(+) lymphocytes count was 100/uL (range 5-620) and in 27 (82%) patients, CD4^(+) lymphocytes count were less than 200/uL. For 13 patients (40%), malignancy was initial presentation of HIV infection. Excluding patients initially diagnosed as malignancy, median follow-up duration from the first visit to diagnosis of malignancy was 36 months (range 3-96). Non-Hodgkin's lymphoma was the most frequent malignancy (13 patients), followed by Kaposi's sarcoma (7), Hodgkin‘s disease (3), acute myeloid leukemia (1), and other solid cancer (9) including one case of anal cancer associated with human papillomavirus. Among 13 patients with non- Hodgkin's lymphoma, 4(31%) achieved the complete remission after chemotherapy and/or radiation therapy, and had been followed without evidence of recurrence. Conclusion : Malignancy was diagnosed in 3.76% of patients infected with HIV. Non-Hodgkin‘s lymphoma is the most prevalent malignancy in HIV patients in South Korea. 목적 : 효과적인 항레트로바이러스 다제요법이 도입됨에 따라, HIV 감염환자들의 수명이 증가되었고, 이에 따라 HIV 감염환자에서 악성종양의 중요성 또한 증가하고 있다. 본 연구의 목적은 우리나라 HIV 감염환자에서 악성종양의 유병률과 호발하는 악성종양의 특성을 밝히는 것이다. 재료 및 방법 : 1986년부터 2005년까지 서울대학교병원에서 치료를 받은 HIV 감염환자의 의무기록을 후향적으로 분석하였고, 병리학적 검사 결과를 검토하여 악성종양이 진단된 환자들을 대상으로 연구를 시행하였다. 결과 : 총 850명의 환자 중, 32명(3.76%)에서 33예의 악성종양이 진단되어, 악성종양의 발병률은 1,000인년 당13.0명(95% 신뢰구간: 8.6∼17.4명)이었다. 그 중 남자는 30명이었고, 악성종양 진단 당시 연령의 중간값은 46 (29-70)세이었다. 악성종양 진단받을 당시, CD4 림프구 수의 중간값은 lOO/uL (5-620 uL) 이었고, CD4 림프구수가 200/ uL 미만인 환자가 27명(82%)이었다. 악성종양에 대한 검사 도중에 HIV 감염사실이 밝혀진 환자가 13명(40%)이었다. HIV를 진단 받은 후 악성종양이 발병한 환자들에서, HIV 진단 후 악성종양의 발병까지는 평균 36개월(3-96개월)이 걸렸다. 13명의 HIV 감염 환자에서 진단된 비호지킨림프종이 가장 흔한 악성종양이었고, 이외에 카포시육종이 7명, 호지킨병이 3명, HPV와 연관된 항문암이 1명의 HIV 환자에서 진단되었다. 그 밖에 급성백혈병, 방광암, 췌장장, 폐암, 진행성위암, 갑상선암, 간세포암, 후두암이 각각 1예씩 진단되었다. 비호지킨림프종이 진단된13명 환자 중, 4명(31%)은 항암치료 및 방사선치료를 받아 완전관해가 되었고, 현재 재발의 증거 없이 외래에서 경과 관찰 중이다. 결론 : 우리나라 HIV 감염환자에서 악성종양의 유병률은 3.76%이었고, 비호지킨림프종이 가장 흔한 악성종양이었다.

        金鍾涉,朴重錫,曺台純 慶尙大學校 1980 論文集 Vol.19 No.1

        In order to investigate the variation in the pattern of origin of the celiac and the cranial mesenteric arteries, forty-four specimens (guinea pig) anesthetized by ethyl ether were heparinized and exsanguinated. Neoprene latex solution was injected into common carotid artery of thirty-two specimens for gross dissection. Twelve specimens angiography were prepared by injecting fifty per cent of barium sulfate solution into exsanguinated animals and then radiographed on a soft X-ray apparatus (Shimadzu Waltes 60). 1. The celiac artery and the cranial mesenteric artery were observed to be arosed mostly from a common trunk of the abdominal aorta, the celiac-cranial mesenteric trunk(68.2%), but in three animals from thirty specimens an anastomotic branch was examined between the abdominal aorta and the celiac artery(6.8%). 2. The celiac artery and the cranial mesenteric artery were branched from separated origin of the abdominal aorta(31.8%), and an anastomotic branch was examined between the celiac artery and the celiac-cranial mesenteric trunk(6.8%) in three animals from thirty specimens. 3. the hepatic artery was arosed from three different origin such as celiac artery branched from celiac-cranial mesenteric trunk(45.4%), celiac-cranial mesenteric trunk(22.2%) and the celiac artery branched from the abdominal aorta(31.8%).

        Choanal polyps can be defined as paranasal sinus polyps that pass through sinus ostia and protrude into the boundary between the nasal cavity and nasopharynx-the choana. The most common choanal polyp is the antrochoanal polyp, but sphenochoanal and ethmoidochoanal polyps are rarer. We experienced a case of choanal polyp originating from the nasal mucosa of the sphenoethmoid recess, not from the paranasal sinuses. It was removed with intranasal endoscopy, and 6 months follow-up has not shown any recurrence. So we report this very rare case with review of literatures.

        Rhabdomyosarcoma, which is a very rare and highly malignant disease in urologic field, has three categories-pleomorphic, alveolar, embryonal, and may arise from any part of the body that contains embryonal mesenchyme, whether striated muscle tissue is present or not. The common site in the genitourinary tract are prostate, bladder, and vagina. Herein we experienced a rhabdomyosarcoma of the pelvic cavity and reviewed literature briefly.

      • TiO₂-CaSO₄와 TiO₂-CaCO₃계의 고상반응기구 : TiO₂의 반응성 및 상형성 Reactivity of TiO₂and Phase Forming

        김홍대,한인섭,유태석,정윤중 明知大學校 産業技術硏究所 1986 産業技術硏究所論文集 Vol.5 No.-

        For to detect the mechanism of the product phase and the assignment of the two reactant on the solid state reaction of TiO₂ with the CaSO₄ and CaCO₃ respectively at the reaction temperature 900℃ - 1400℃, the refractive microscope, scanning electron microscope, and electron dispersive spectroscope analysis were examined. For the reaction of TiO₂ with CaSO₄ the product phase which earned is CaTiO₃perovskite and from the first, the intermediate product of TiO₂· CaO·SO₂ was formed. However, the main product phase is Ca₃Ti₂O7, which is coexisted in the product layer, at the reaction of TiO₂ with CaCO₃·TiO₂ was diffused into CaSO₄ and CaCO₃ reactant side is both two reaction. Specially, in the case of CaCO₃, the transfer of TiO₂ is rapid through the pore, which was formed with vaporization of CO₂ gas.
