Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

강변여과용 수평집수관을 모사하는 파일럿 규모의 모래통 실험을 수행하였으며, 다양한 출구유속에 대한 수평집수관에서의 수두분포를 구하였다. Kim24)이 수행한 실험실 규모의 수평집수관에서의 손실수두에 Kim25)이 개발한 이론 즉, 작은 규모의 수평집수관에서의 손실수두로부터 큰 집수관의 손실수두를 계산하는 방법을 적용하여 본 연구의 관측치와 비교함으로써 Kim25)의 이론이 타당함을 알 수 있었다. 또한, 이들의 이론을 적용하여 본 연구에서의 관측치로부터 실규모 집수관에서의 수두분포를 구하는 방안을 예를 들어 설명함으로써 강변여과의 수평집수관 설계방법을 제시하였다. A pilot-scale sand-box experiment simulating a lateral of collector well used in riverbank filtration was performed, and hydraulic head distributions along the lateral were measured according to the various drawdowns at the well. The results of this experiment were compared to the predicted values obtained using a theory previously developed by Kim25) in order for its validation. This theory predicts the head loss in a large-scale lateral given the loss in a small-scale one, and to have actual values for comparison, the results from a lab-scale experiment previously performed by Kim24) were employed. Comparing the experimental values to the extrapolated value indeed confirmed the validity of the theory. A procedure to determine the hydraulic head distribution of a practical-scale lateral was also presented applying the theory to the experimental result of this study in an effort to show the process of lateral design for riverbank filtration.

김영운,정숭룡,이승호,이종호,김창룡,박문성,류선열 大韓顎顔面成形再建外科學會 1995 Maxillofacial Plastic Reconstructive Surgery Vol.17 No.4

Tuberculosis, a chronic infectious granulomatous disease, is preumed to be quite a rare entity. Because of the development of chemotherapy and the improvement of nutritional conditions, incidence of tuberculosis have reduced. For these reasons, tuberculosis may be overlooked in the differential diagnosis whenever dealing with a submandibular swelling. Diagnosis of tuberculous lymphadenitis consists of historical data, physical findings, laboratory tests and histologic examination. The treatment of choice seems to be surgical excision and long term antituberculosis chemotherapy. Surgery provides a rapid tissue diagnosis, because the histological examination of the excisional biopsy is the most reliable diagnostic test. This is the report of a case of tuberculous cervical lymphadenitis on left submandibular area with no evidence of the involvement of lung.

씨름선수에서 체중 감량과 회복기의 Leptin과 PAI-1 변화

김용운,도경오,권태동,박덕일,장응찬,박소영,김종연,이석강 대한스포츠의학회 2000 대한스포츠의학회지 Vol.18 No.2

Obesity which is defined as accumulation of excess body fat, is central factor of insulin resistance syndrome. Recently, it is revealed tat adipose tissue is not simply an energy storage organ but it also secretes a variety of molecules which affect the metabolism of the whole body, those are leptin and plasminogen activator inhibitor-1(PAI-1). Therefore, leptin and PAI-1 are increased in the obese state. Leptin regulates energy homeostasis and satiety and PAI-1 regulates fibrinolytic system. For these reasons, elevated levels of leptin and PAI-1 are considered as link factors between obesity and insulin resistance syndrome. However, the exact regulating mechanism for serum levels of leptin and PAI-1 is not fully understood yet. In this study, to evaluate the regulating mechanisms of serum levels of leptin and PAI-1 according to the weight changes, we measured leptin, PAI-1, physical, metabolic, and endocrine parameters during 10 days of weight reduction and 10 days of regain period in 7 young athletes. The mean body weight change was -4.7 kg(5.0%) in the weight reduction period and -2.4 kg(2.5%) in the weight regain period compared to baseline value. Baseline level of leptin in athletes was 1.7±0.66 ng/ml, which was significantly correlated with body weight, BMI, percent body fat, body fat mass, triglyceride, insulin, and PAI-1. Baseline level of PAI-1 in athletes was 16.6±5.26 ng/ml, which was significantly correlated with body weight, BMI, triglyceride, insulin, and leptin. Leptin was decreased to 0.7±0.39(44% of the basaline value) in the weight reduction period, and increased to 1.9±0.64(119% of the baseline value) in the regain period. PAI-1 was decreased to 7.4±2.72(44% of the basaline value) in the weight reduction period, and increased to 22.8±7.33(138% of the baseline value) in the regain period. The changes of leptin during weight reduction period were significantly correlated with the changes of insulin(r=0.890, P<0.01) and triglycerides(r=0.874, P<0.01). The changes of PAI-1 during weight reduction period were significantly correlated with the changes of FFA(r=0.889, P<0.01) and triglycerides(r=0.869, P<0.05). The changes of both leptin and AAI-1 during weight regain period were significantly correlated with the changes of insulin(r=0.755 and 0.849, P<0.05, respectively). In summary, these results suggest that serum levels of leptin and PAI-1 were affected by weight cycling, the percentages of change were more greater than that of weight change, and rebound phenomena were occurred during weight regain period.

2,4,6-Collidinium Dichromate에 의한 알코올의 산화 특성 연구

김선일,한종수,나재운 조선대학교 생산기술연구소 1991 生産技術硏究 Vol.13 No.1

2, 4, 6-Collidinium dichromate(CDC) is more, stable. nonhygroscopic, and milder than other chromium(VI)oxidants. The new oxidant was characterized via rate of oxidation. CDC with pyridinium P-toluenesulfonate(PPTS) in dichloromethane was effective in oxidation of allylic, benzylic, and secondary alcohols to the corresponding carbonyl compounds at room temperature. while CDC alone did not oxidize above alcohols. Oxidation of ally lie and benzylic alcohols progressed more repididly than that of secondary alcohols. When molecular sieve(MS)was added to the CDC-PPTS system, rate of oxidation and yields increased. Saturated aliphatic primary alcohols were decomposed in two system, CDC-PPTS and CDC-PPTS system added MS. The oxidation selectivity of CDC-PPTS system was increased about 1.75 times than that of PDC-PPTS system.

극저준위 감마선 분광시스템의 백그라운드 저감화를 위한 중성자 차폐체 설계

김태욱,박종묵,박종길,신상운,전재식 대한방사선 방어학회 2001 방사선방어학회지 Vol.26 No.2

극저준위 방사능측정시스템의 백그라운드에 영향을 주는 중성자를 차폐하기 위한 차폐체를 설계하였다. 중성자 차폐방법은 고 밀도 폴리에틸렌을 이용하여 고속중성자를 감속한 후 B4C를 이용하여 감속된 열중성자를 흡수하는 방법을 이용하였다. 몬테카를로 모사방법인 MCNP4B 코드를 이용하여 계산한 결과 고 밀도 폴리에틸렌의 두께가 10 cm 일 때 열중성자속이 최대가 되는 것으로 나타났으며 감속된 중성자의 흡수는 용제에 자연상태의 B4C 분말을 30 w% 섞을 경우 2 mm의 두께에서 94%의 중성자 흡수가 일어나는 것으로 나타났다. 또한 몬테카를로 모사를 통한 계산결과의 타당성 여부를 조사하기 위하여 중성자 차폐실험 장치를 제작하여 실험 결과와 비교하였으며, 비교 결과 실험값과 일치하는 것으로 나타났다 In order to shield the neutrons affecting the background of Low Level Gamma Ray Spectrometer, a neutron shielder was designed. The method used in this study for neutron shielding was the deceleration of fast neutrons by high density polyethylene(HDPE) and the absorption of those slowing-down neutrons by B4C. The calculation results of neutron interaction in HDPE using Monte Carlo simulation code MCNP4B showed that the thermal-neutron flux was maximum at 10 cm thickness of HDPE. The results also showed that 95% of the thermal neutrons were absorbed by 2 mm thickness of B4C absorber consisted of 30 w% B4C and 70 w% polymer. The results of the Monte Carlo calculation were in good agreement with the experimental value obtained by a neutron shielding apparatus designd for this purpose.

40X40 픽셀 어레이 CMOS 실리콘 망막칩의 설계 및 제조

김종문,김호운,신장규,히로오 요네즈 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

In this research, we have designed and fabricated a 40X40 pixel array retina chip which performs edge extraction by using CMOS standard process. The functions of photoreceptors, horizontal cells and bipolar cells have been implemented with semiconductor devices and circuits. In previous retina chips, spatial smoothing of input image has been implemented by resistive networks, which occupy a large chip area with a reduced area for effective photosensing due to a large number of required metal wires for interconnection. In this research, we have fabricated a retina chip which simplifies the wiring between pixels by using distributed-MOSFETs.
