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.

The prevalence of PPNG among pretreated gonorrhoeae cases isolates at the VD clinic of Choong-ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1990, 162 strains of N.gonorrhoeae were isolated, among which 80 were PPNG. The prevalence of PPNG in Seoul showed increased tendency till 1987, thereafter, it has been stationary.

Molecular Theory of Plastic Deformation (Ⅲ)$^*$

Kim, Jae-Hyun,Ree, Tai-Kyue,Kim, Chang-Hong Korean Chemical Society 1981 Bulletin of the Korean Chemical Society Vol.2 No.3

(1) The flow data of f (stress) and ${\dot{s}$ (strain rate) for Fe and Ti alloys were plotted in the form of f vs. -ln ${\dot{s}$ by using the literature values. (2) The plot showed two distinct patterns A and B; Pattern A is a straight line with a negative slope, and Pattern B is a curve of concave upward. (3) According to Kim and Ree's generalized theory of plastic deformation, pattern A & B belong to Case 1 and 2, respectively; in Case 1, only one kind of flow units acts in the deformation, and in Case 2, two kinds flow units act, and stress is expressed by $f={X_1f_1}+{X_2f_2}$where $f_1\;and\;f_2$ are the stresses acting on the flow units of kind 1 and 2, respectively, and $X_1,\;X_2$ are the fractions of the surface area occupied by the two kinds of flow units; $f_j=(1/{\alpha}_j) sinh^{-1}\;{\beta}_j{{\dot{s}}\;(j=1\;or\;2)$, where $1/{\alpha}_j\;and\;{\beta}_j$ are proportional to the shear modulus and relaxation time, respectively. (4) We found that grain-boundary flow units only act in the deformation of Fe and Ti alloys whereas dislocation flow units do not show any appreciable contribution. (5) The deformations of Fe and Ti alloys belong generally to pattern A (Case 1) and B (Case 2), respectively. (6) By applying the equations, f=$(1/{\alpha}_{g1}) sinh^-1({\beta}_{g1}{\dot{s}}$) and $f=(X_{g1}/{\alpha}_{g1})sinh^{-1}({\beta}_{g1}{\dot{s}})+ (X_{g2}/{\alpha}_{g2})\;shih^{-1}({\beta}_{g2}{\dot{s}})$ to the flow data of Fe and Ti alloys, the parametric values of $x_{gj}/{\alpha}_{gj}\;and\;{\beta}_{gs}(j=1\;or\;2)$ were determined, here the subscript g signifies a grain-boundary flow unit. (7) From the values of ($({\beta}_gj)^{-1}$) at different temperatures, the activation enthalpy ${\Delta}H_{gj}^{\neq}$ of deformation due to flow unit gj was determined, ($({\beta}_gj)^{-1}$) being proportional to .$k_{gj}$, the jumping frequency (the rate constant) of flow unit gj. The ${\Delta}H_{gj}\;^{\neq}$ agreed very well with ${\Delta}H_{gj}\;^{\neq}$ (self-diff) of the element j whose diffusion in the sample is a critical step for the deformation as proposed by Kim-Ree's theory (Refer to Tables 3 and 4). (8) The fact, ${\Delta}H_{gj}\;^{\neq}={\Delta}H_{j}\;^{\neq}$ (self-diff), justifies the Kim-Ree theory and their method for determining activation enthalpies for deformation. (9) A linear relation between ${\beta}^{-1}$ and carbon content [C] in hot-rolled steel was observed, i.e., In ${\beta}^{-1}$ = -50.2 [C] - 40.3. This equation explains very well the experimental facts observed with regard to the deformation of hot-rolled steel..

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.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

Handover Ranging Power Adjustment Using Uplink Channel Information in IEEE 802.16e/m Ji-Su Kim, and Jae-Hyun Kim, ETRI Journal, vol.32, no.5, Oct. 2010, pp.823-826.

This letter proposes a handover ranging power adjustment scheme to improve handover performance. Incorrect ranging power can degrade handover performance due to the increased handover latency; therefore, the proposed scheme exploits the uplink channel information to adjust the uplink handover ranging power. Simulation results demonstrate that the proposed scheme reduces call outage probability by 33% compared to that of the conventional scheme. It also improves the number of users who satisfy the system requirements for handover interruption time.

A fourteen-month-old intact female Poodle was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Chungnam National University. The patient was presented with history of vomiting, inappetence, ataxia, insomnia, tachypnea and convulsion for 5 days. Biochemical examination revealed BUN (254.2 mg/dl), creatinine (9.22 mg/dl) and phosphate (14 mg/dl). Epithelial cells of urinary tract, neutrophils, macrophages, a large number of gram negative and smaller number of gram positive bacteria were presented on urine test. Ultrasonographic findings show hyperechogenic kidney and indistinguishableness of renal cortex and medulla. Based on the results of examination described above, this case was diagnosed as acute renal failure with interstitial nephritis by urinary tract infection (UTI). Treatments with fluids therapy, diuretics, and peritoneal dialysis during hospitalization showed good results with no clinical signs.

산지하천에서 빛과 초식에 의한 부착조류의 생체량변화

김현우,김현주,김진수,윤해순,주기재 東亞大學校附設基礎科學硏究所 1998 基礎科學硏究論文集 Vol.15 No.1

빛과 초식에 의한 부착조류의 생체량 변화에 대한 영향을 평가하기 위하여 자연기질과 인공기질(유약을 칠하지 않은 타일: 3.7×9.5×2cm)을 이용하여 부분적으로 음지화된 2차 산지하천에서 실험하였다. Open canopy(상대적 빛 투과율: 20∼50%, chl. a: 9.5±3.0㎎/㎡, n=25)에서는 closed canopy(<6% 상대적 빛 투과율, 3.2±0.9㎎/㎡, n=17)보다 높은 부착조류 생체량을 유지하였다. 하천 주변식생의 잎 성숙과 잦은 강우에 의해서 여름의 부착조류 생체량은 봄과 겨울에 비하여 낮았다. 봄에 인공기질에 부착조류가 부착하는 속도는 겨울보다 빨랐으며 겨울에는 자연기질 수준(8∼9㎎/㎡)에 이르기 까지 최소 5∼6주 정도 소요되었다. 초식자인 다슬기는 출입을 제한한 실험구에서는 출입이 허용된 대조구보다 약간 높은 생체량(AFDW, chl. a)을 보였다. 결론적으로 빛이 부착조류 생체량에 증가에 미치는 영향은 초식 보다는 더 큰 것으로 사료된다. Effects of light and grazing on the biomass development of periphyton were evaluated using natural and artificial substrata (unglazed tile: 3.7×9.5×2cm) in a partially shaded 2nd order mountain stream. In open canopy (relative light input 20∼50%), a relatively high biomass (chl. a: 9.5±3.0㎎/㎡, n=25) was maintained than that of closed canopy (<6% of light input, 3.2±0.9㎎/㎡, n=17). Due to shading and frequent rainfalls, biomass was lower during the summer than in the spring and winter. During the spring, colonization of periphyton on artificial substrata occurred faster than in winter and it took a minimum of 5∼6 weeks to reach the biomass of natural substrata (8∼9㎎/㎡). When snails were allowed to freely enter the chamber (mean density: 114 ind./㎡) with artificial substrata, biomass accumulation (chl. a, AFDW) was low compared to the snail excluded enclosure (50∼90% of ungrazed substrata). It was concluded that the light input on periphyton biomass in a partially shaded stream played a more important role than grazing.
