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.

정재민(Jae Min Jeong),박재영(Jae Young Park),이종진(Jong Jin Lee),김용운(Yong Woon Kim),김승현(Seung Hyun Kim) 大韓環境工學會 2013 대한환경공학회지 Vol.35 No.5

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.

This study aims to improve the Evacuation Performance of the Discount-store in underground that is rapidly growing new shopping store in Korea. In this paper, The architectural properties of the floor plan and section was reviewed with egress focus, occupant load density of the Discount-store was surveyed and the procedure and method of performance based egress design for this occupancy was analysed with SIMULEX model and calculation method. As a result of modeling, mire longer svsilable safe egress time (ASET) is expected than required safe egress time (RSET) in underground discount-store. In order of improve the Evacuation Performance for this based on occupant load density and review of shopping cart's structure and size and maximum escape capacity of the cash counter.

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.

가변 부하를 위한 RF 전원 공급기 설계

金允溟,朴圭喆,崔鍾云,朴宰煥 단국대학교 1992 論文集 Vol.26 No.-

In the RF gas discharge system the load varies frequently by the operational environment. And it is often necessary to change the matching network to provide the maximum possible power transfer from the oscillator to the RF load. An Rf oscillator whose variable operating frequency is between 20 and 30 MHz and whose output RF power is about 200 watts was designed to solve this problem. The conversion efficiency from the DC power was about 80% It is found that the output oscillating frequency which gives minimum RF reflections from the loads follows automatically to the changes of the load or of the operating conditions. It is also found that the output frequency decreases with the larger load shunt capacitance.

김종운,김수관,김수흥,정태영 대한악안면성형재건외과학회 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.3

We report a case in which a right mandibular incisor was impacted beneath an odontoma in the anterior mandible. An odontoma at the symphyseal region was removed under general anesthesia, and bone was grafted. Tooth #41, which was beneath the lesion, was extracted and transplanted to its original site. It was splinted with resin for 2 weeks and was checked at intervals during that time. After 4 months, it was filled endodontically with calcium hydroxide.

This is to report functional treatment, as mechano-therapy, of candylar fracture in cases of growing patients. Benoist's appliance was used in 3 cases condylar fractures, provides extraral elastic forces to external pterygoid muscle. The appliance providing guided exercise of masticatory muscles induces transformative growth of trauma-tic condyles. The results were as follow; 1. Early exercise preventes ankylosis of fractured condyle. 2. Optimal physical exercise therapy induces the normal growth pattern by muscular training and bony remodeling of fractured condyle in children.

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.
