TCP와 UDP 트래픽의 통합 스케줄링 알고리즘에 관한 연구

강정하,김은기 한밭대학교 산업과학기술연구소 2001 논문집 Vol.5 No.-

In this paper, we propose a new scheduling algorithm that provides fair scheduling method for TCP and UDP traffic. A router in network calculates target traffic rate for each flow when it starts packet drop. Then the router increases drop rate for flows that generate more traffic than target traffic rate. The TCP friendly flows reduce sending rate in response to increment of drop rate. But, the flows that do not follow TCP congestion control send their own traffic regardless of packet drops. The drop rate of unresponsive flow is increased more and more at router and consequently bandwidth is assigned fairly to all flows.

강은하,장종언 대한치과교정학회 1999 대한치과교정학회지 Vol.29 No.4

이 연구의 목적은 II급 부정교합의 치료를 위해 경부경인 헤드기어(cervical pull headgear)를 사용할 때, 치료에 불리한 요인으로 작용한다고 언급되는 효과들이 실제로 발현되는지의 여부와 안모의 성장유형에 따라 그 차이가 존재하는지를 알아 보고자 함에 있다. 이를 위해서 삼성서울병원 치과교정과에서 II급 부정교합으로 진단되어 경부견인 헤드기어로 치료받은 환자중, 성장기에 있으면서 비발치 치료를 받은 환자를 연구대상으로 선별하였다. 그리고 연구대상을 “ 후안면/전안면 고경비 ”에 따라 수직성장군과 수평성장군으로 분류하였다. 수직성장군 15명(남자5AID, 여자10명)과 수평성장군 11명(남자4명, 여자7명)의 치료전, 후의 두부방사선규격사진상에서 SN-PP angle. SN-GoGn angle, SN-MP angle, PFH/AFH ratio, SN to 6, PP to 6 등을 계측하고, 비교분석하여 다음의 결과를 얻었다. 1) 수직성장군에서 구개평면이 전하방으로 경사되었다. 2) 수평성장군에서 후안면/전안면 고경비가 증가하였다. 3) 수직성장군과 수평성장군 모두에서 하악평면각은 변화하지 않았다. 4) 상악대구치의 정출양에 있어서 수직성장군과 수평성장군의 차이는 없었다. The purpos of this study is to investigate the negative effects of cervical pull headgear and to compare the differences between the two groups of growers-vertical grower and horizontal grower group-which are classified by the posterior-anterior facial height ratio. Initial and final lateral cephalograms were taken for 26 patients including 15 vertical growers and 11 horizontal growers : also, 3 angular measurements and 4 linear measurements were evaluated. The following results were found. 1. The palatal plane was tipped anteroinferiorly in the vertical grower group. 2. The posterior facial height/anterior facial height ratio was increased in the horizontal grower group. 3. The Mandibular plane angle remained stable on both groups. 4. There was no significant difference between the two groups in the amount of maxillary molar extrusion.

In the present study the hepatoprotective and antioxidative effects of Epimedium koreanum (EK) and Salicornia herbacea (SH) were investigated against carbon tetrachloride (CCl_(4))-induced liver damage in rats. EK and SH (100 mg/kg) were administered into rats intraperitoneally (i.p) for 2 weeks. After CCl_(4) a dose of 3.3ml/kg was administered to induce hepatotoxicity. This antioxidative effects of EK and SH on CCl_(4) -treated rats were measured through the activity of Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) in serum and Superoxide dismutase (SOD), Catalase (CAT) in liver tissue. EK or SH-administered and CCl_(4) -treated (ECT or SCT) groups showed inhibitory effects in AST and ALT activities compared to CCl_(4) -treated control (CTC) group. SOD and CAT in ECT and SCT groups were increased compared to those of CTC group.

최은정,강상균,양승하,김대중,김의한 순천향의학연구소 1996 Journal of Soonchunhyang Medical Science Vol.2 No.2

Immunohistochemical studies were carried out to observe the expression of p53 protein and PCNA in transitional cell carcinoma (TCC), then analyzed according to the tumor grade and progression. 38 cases of TCC consist of 13 cases grade Ⅰ, 12 cases grade Ⅱ and 13 cases grade Ⅲ respectively. Results obtained are as follows. 1. p53 protein expression was seen in 60% of cases(15 out of 38 cases) In the poorly differentiated area and infiltrated lesion, tumor cell showed more strong positive reaction of p53 protein compared with well differentiated area. 2. All of 38 cases of TCC showed PCNA positive expression. The more strong positivity was seen in the poorly differentiated area and the more intense positive reaction was noted in the basal layer of the tumor nests. 3. The above results showed that positivity of p53 protein and PCNA are closely related with tumor cell differentiation(grade) and progression. It is concluded that positive reaction of p53 protein and PCNA may contribute to detection of tumor growth and prognosis of patient.

박은하,도연실,양정채,강미라,서현주,정숙인,손준성,기현균,오원섭,백경란,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.

p-형 Si(100) 기판 위에 성장시킨 Bi_(3.25)La_(0.75)Ti₃O_(12) (BLT) 박막의 전기적 특성

최은경,박문흠,김현주,하태곤,강민주,김상수 昌原大學校 基礎科學硏究所 2003 基礎科學硏究所論文集 Vol.15 No.-

Bi₃zsLa(0.75)Ti₃0_(12) (BLT) thin film have been grown on p-type Si(l00) substrates by a sol-gel spin coating process. The structure and surface morphology of the film were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEMI. Furthermore, the electrical properties were examined by capacitance-voltage ( C-V) characteristics by using a LF Impedance Analyzer(HP 4192A). XRD measurement show layered perovskite structure with a single phase in BLT thin film annealed at 700C for 30 min in oxygen. The measured grain size of BLT on Si is about 0.04 - 0.1 pn. From the cross-sectional SEM image, BLT film thickness is measured to be 0.4 pm. The C-V characteristic hysteresis curves show that the NIFS (metal-fexroelectric-semiconductor) structure has memory effect. The memory window decreases, with increasing frequency at MFS structure. And it is found that the memory window increases as the applied voltage to the ferroelectric capacitor is increased. These phenomena may be due to polarization reversals of the BLT ferroelectric film and because of the charge injection from Si substrate into the ferroelectric thin film. The results obtained indicate that the present BLT films are suitable for making ferroelectric field effect transistor(FeFET) memory.

손지언,장태원,김윤규,홍영습,정갑열,김동일,이강진,하남진,김상범,김준연 대한산업의학회 2001 대한직업환경의학회지 Vol.13 No.3

목적 : 본 연구는 수근관 증후군의 발생위험이 높은 작업형태에 종사하는 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장과 목재소 근로자에서 근전도검사를 이용하여 수근관 증후군의 유병률을 조사하고자 하였다. 방법 : 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장 근로자 69명과 목재소 근로자 17명을 실험군으로, 관리직, 경리, 경비등 상지의 단순반복작업이 없는 근로자 28명을 대조군으로 선정하여, 작업적 및 병력조사, 이학적 검사와 근전도검사를 통해 수근관 증후군의 유병률을 조사하였다. 결과 : 수근관 증후군의 유병률은 육류 및 어류 가공 사업장과 목재소에서 각각 26.09 % (18명)와 29.41 %(5명)로 조사되었으며, 육류 및 어류가공사업장과 목재소 근로자를 '7년 이상과 미만의 작업기간'으로 층화하여 비교한 결과 '상지부위의 통증 호소 유무', 'Visual Analogue Scale(VAS: 총 10점) 4점 이상 여부', 'Tinel teat 양성 유무', 'Phalen test 양성 유무'는 모두 단기 작업근로자군에서 양성의 빈도가 증가되었고 '수근관 증후군 유무'는 장기작업근로자군에서 양성의 빈도가 증가되었다. 결론 : 육류 및 어류 가공 사업장과 목재소의 수근관 증후군 유병률은 각각 26.09 %와 29.41 %로 육류 및 어류 가공 사업장과 목재소는 1996년 OSHA가 지정한 바와 같이 위험한 작업요인이 있는 작업장으로 분류하여 관리되어야 할 것으로 생각된다. Objectives : This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method. Methods : Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS. Results : 18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms (complaint of upper extremities, Visual Analogue Scale ≥4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group(p<0.05). The prevalence of symptoms and signs were higher in short term workers(<7 years), but the prevalence of CTS was higher in long term workers(≥7 years). Conclusions : The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996
