리눅스 클러스터 서버 상에서 RTSP 기반의 VOD 스트리밍 시스템의 설계 및 구현
홍기호,김영진,최황규 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A
Linux cluster Server makes a high performance PC cluster system, and provides scalablity and availability as compared with an expensive single server. In this paper, we design and implement a VOD streaming service system to serve video and audio streaming services on the Linux cluster serve. Our Streaming server supports the MS Window Media Format based on the RTSP streaming protocol.

In this paper, we propose a new content-aware load balancing technique based on histogram equalization, which finds a workload characterization of cluster web servers and equally assigns the workload to each server node using hashing and its histogram transformation. As the workload, we consider the number of requests for each file and the size of the file, which are extracted from web log in cluster web servers. To show the efficiency of our load balancing technique, we compare it with a traditional Round-Robin and a workload-aware load balancing(WARD) by simulation with respect to the load balancing efficiency.

Authors and experienced fifteen cases of the pineal tumors during about 5 years from October, 1977 to September, 1982, which were diagnosed with brain C-T scanning. The details of clinical evaluation and follow up of 15 cases of the pineal tumors are presented. The following results were obtained. 1) The age group below age of 20 years in predominant and include 11 cases (73%) of 15 cases, and male is predominantly much than female. 2) On the neurological examination at admission, the RICP signs were showed in 15 cases, Parinaud's syndrome showed in 6 cases, cranial nerve palsy in 8 cases and DI symptom in 5 cases of all 15 cases. 3) In the follow up study, brain CT was more effective than any other conventional neuroradiologic technique. 4) 8 cases of all 15 cases have had normal life in follow up period with minium of 6 months and maximum of 6 months and maximum of 5 years, and one case with mild neurological deficit has been spent life for about 12 months. 5) Of 6 cases died within 2 years, 3 cases had insufficient treatment and 3 cases had sufficient treatment, of whom one had tumor recurrence at primary site and dissemination to spinal epidural space and other two cases were suspected to have clinical dissemination to spinal cord. 6) On the basis of high survival rate in 9 cases of 12 cases who were treated completely, we thought that good survival rate in the patient with pinealoma will be resulted from a series of planned treatment, including early diagnosis, correction of hydrocepalus, surgical intervention and irradiation.

The purpose of this study is to investigate the material characteristics and strength properties of concrete mixed with waste incinerated bottom ash(BA), and to evaluate the leaching of environmentally harmful heavy metals from the bottom ash itself and from hardened concrete mixed with bottom ash. For this purpose, two reference mixed with W/C ratio of 0.45 and 0.55 were used, and the replacement proportion of BA was varied with ratios of 0, 30, 50, 70 and 100% by volume of fine aggregate in the reference mixes. The variation of compressive and splitting tensile strength, workability and unit weight of concrete were considered. Test results showed that the strengths, workability and unit weight decreased with increase in proportion of BA replaced. Leaching test results showed that there would be no environmentally harmful problem from using BA as substitutes of fine aggregates in concrete.
관절 조직과 상처에서 분리된 Vancomycin-intermediate Staphylococcus aureus 2예

Since its first isolation in 1997, vancomycin-intermediate Staphylococcus aureus (VISA) has been a clinical concern because it may lead to treatment failure. Up to the present, there were two reports of clinical VISA cases in Korea. We now report two additional cases of VISA with the minimum inhibitory concentration (MIC) of 4 μg/mL. The first patient was a 59 yr-old man who had undergone total hip replacement arthroplasty in 1999 due to avascular necrosis of femur heads. He had recurrent episodes of infected hip caused by methicillin-resistant Staphylococcus aureus (MRSA) and was treated with vancomycin. He underwent replacement operation of prosthesis. Cultures of joint fluid and joint tissue grew S. aureus. Vancomycin MIC as determined by a broth microdilution method was 4 μg/mL for the both isolates. The patient was treated with high enough doses of vancomycin to maintain serum trough concentrations at 20-25 μg/mL for 52 days and was discharged. The second patient was a 57 yr-old man with diabetes. He lost consciousness from drinking. After recovery of consciousness, he was diagnosed with aspiration pneumonia. MRSA and Acinetobacter baumannii were cultured from sputum and the patient was treated with vancomycin and meropenem. During hospitalization, bed sores developed in his ankle and back. A wound culture from the sore grew S. aureus with vancomycin MIC of 4 μg/mL. Since infection was localized, systemic antibiotics did not seem necessary, and the patient was transferred to another hospital for isolation and management. (Korean J Lab Med 2008;28:444-8)

The purpose of this study is to investigate the material characteristics and strength properties of concrete mixed with wastewater sludge, and to evaluate the leaching of environmentally harmful heavy metals from the wastewater sludge itself and from hardened concrete mixed with wastewater sludge. For this purpose, a reference mix with W/C ratio of 0.45 was used and the replacement proportion of wastewater sludge was varied with ratios of 0, 30, 50, 70 and 100% by volume of coarse aggregate in the reference mix. The variations of compressive and splitting tensile strength, workability and unit weight of concrete were considered. Test results showed that the strengths and unit weight decreased with increase in proportion of wastewater sludge replaced, but workability increased. Leaching test results showed that there would be no environmentally harmful problem from using wastewater as substitutes of coarse aggregates in concrete.

Subdural empyema is a neurosurgical the mortality of which continues to be as high as 40% in mordern reported series. It is also a curable lesion, and the outcome of treatment has been demonstrated to be directly related to the promptness of diagnosis and appropriate surgical drainage. Recently, we have operated upon two cases of intracranial subdural empyema secondary to acute facial furuncle and postoperative craniectomy. Reviewing these two cases and other literatures, we are going to describe about cases, symptoms and signs, and methods of diagnosis and treatment of subdural empyema.

Background: Next-generation sequencing (NGS) can detect many more microorganisms of a microbiome than traditional methods. This study aimed to analyze the vaginal microbiomes of Korean women by using NGS that included bacteria and other microorganisms. The NGS results were compared with the results of other assays, and NGS was evaluated for its feasibility for predicting vaginitis. Methods: In total, 89 vaginal swab specimens were collected. Microscopic examinations of Gram staining and microbiological cultures were conducted on 67 specimens. NGS was performed with GS junior system on all of the vaginal specimens for the 16S rRNA, internal transcribed spacer (ITS), and Tvk genes to detect bacteria, fungi, and Trichomonas vaginalis. In addition, DNA probe assays of the Candida spp., Gardnerella vaginalis, and Trichomonas vaginalis were performed. Various predictors of diversity that were obtained from the NGS data were analyzed to predict vaginitis. Results: ITS sequences were obtained in most of the specimens (56.2%). The compositions of the intermediate and vaginitis Nugent score groups were similar to each other but differed from the composition of the normal score group. The fraction of the Lactobacillus spp. showed the highest area under the curve value (0.8559) in ROC curve analysis. The NGS and DNA probe assay results showed good agreement (range, 86.2-89.7%). Conclusions: Fungi as well as bacteria should be considered for the investigation of vaginal microbiome. The intermediate and vaginitis Nugent score groups were indistinguishable in NGS. NGS is a promising diagnostic tool of the vaginal microbiome and vaginitis, although some problems need to be resolved.
