In this paper, we design the simulation environment for evaluating the performance of multiprocessor systems using Futurebus+ as shared bus with various configurations. To evaluate our design of bus simulator, parallel work loads, multiple threads, are generated from single-thread codes trace on the benchmarks: rsa, sieve and 15×15 matrix. Some of the results from the simulation on the benchmarks is presented by graphic user interface. Typical results include the analysis on cache hit ratio, processor utilization and bus congestion ratio according to changes of the number of processor and cache coherency protocol. From the analysis we prove the processor utilization and the bus congestion ratio are greatly depend on cache hit ratio and write-broadcast protocol is more effective than write-invalidate protocols. The simulation environment with the basis of Futurebus+ would be used to evaluate the system performance of shared memory multiple processors.

최은진 ( Eun Jin Choi ),윤현진 ( Hyun Jin Yun ),허재원 ( Jae Won Huh ),이보영 ( Bo Young Lee ) 대한주산의학회 2008 Perinatology Vol.19 No.1

목적: B형 간염 예방 접종 후 항체 생성률은 건강한 만삭아에 비해 면역반응이 약한 미숙아나 저출생 체중아에서 떨어진다는 보고가 있다. 저자들은 실제로 그러한 지 알아보기 위해 제태 연령과 출생체중에 따라 B형 간염 예방 접종 후 항체 생성률을 비교하였다. 방법: 2002년 1월부터 2007년 3월까지 부산 일신 기독 병원에서 B형 간염 예방접종 완료 후 B형 간염 항원, 항체 검사를 받은 968명의 영아를 대상으로 출생 체중과 제태 연령에 따라 분류하여 항체 양성률을 조사하였다. 결과: 제태 연령별 항체 음성률(non-responder or poor-responder)은 28주 이하에서 15.6%, 28주에서 32주 사이에서 11.4%, 32주에서 37주 사이에서 5.8%, 37주 이상에서 1.9%로 제태 연령별 유의한 차이(P<0.001)가 있으며 제태 연령이 증가할수록 상당한 감소를 보였다. 각각의 출생체중별 항체 음성률(non-responder or poor-responder)은 1,000 g 이하에서 16.7%, 1,000 g에서 1,500 g 사이에서 15%, 1,500에서 2,000 g 사이에서 5%, 2,000 g 이상에서 2%로 출생 체중별 유의한 차이(P<0.001)가 있으며 출생체중이 증가할수록 상당한 감소를 보였다. 결론: B형 간염 예방 접종 후 항체 양성률은 출생 체중이 작을수록 제태 연령이 적을수록 떨어졌다. 또한 제태 연령 37주 이상, 출생 체중 2,000 g 이상은 독립적으로 B형 간염 예방 접종 후 높은 항체 양성률과 관련되어 있었다. Purpose: Previous studies have reported that the immune response of hepatitis B vaccine is decreased in preterm or low birth weight babies compared to healthy term babies. To evaluate this notion, we investigated the positive seroconversion rate of hepatitis B antibody after hepatitis B vaccination according to gestational age and birth weight. Methods: We retrospectively studied medical records about the positive seroconversion rate of a total of 968 infants who were given DNA recombinant hepatitis B vaccine as scheduled at II Sin Christian Hospital, Busan from January 2002 to Mar 2007. Results: The postive seroconversion failure rate (non-responder or poor-responder) of hepatitis B antibody by gestational age was 15.6% (<28 weeks), 11.4% (>28 weeks, <32 weeks), 5.8% (>32 weeks, <37 weeks), and 1.9% (<37 weeks). The postive seroconversion failure rate by birth weight was 16.7% (<1,000 g), 15% (>1,000 g, <1,500 g), 5% (>1,500 g, <2,000 g), and 2% (>2,000 g). Conclusion: The seropositive rate of hepatitis B antibody after hepatitis B vaccination decreased as the gestational age and the birth weight decreased. And gestational age more than 37 weeks and birth weight above 2,000 g were independently associated with a higher seropositive rate of hepatitis B antibody after hepatitis B vaccination.

Purpose: Asthma inhalation therapy is important for the treatment of childhood asthma. Therefore, it is necessary to educate patients on the correct inhalation techniques. The purpose of this study was to determine the effectiveness and necessity of educating patients on the correct inhalation techniques. Methods: A total of 86 patients with bronchial asthma and who were over 7 years old were enrolled and educated on handling inhaler devices for 2 years. The inhaler devices used were the diskus (n=27), turbuhaler (n=12) and metered dose inhaler with a spacer (n=47). Trained pharmacists provided the education. Four steps (breathing out prior to inhalation, inhalation, holding the breath, exhaling slowly) that were critical for handling each device were evaluated and each step was scored as good, fair or poor. We evaluated the symptom score (daytime cough, nighttime cough, sleep disturbance and limitation of activity) and lung function before treatment and 4 weeks later. Results: Over 90.0% of the diskus users performed fair to good in each step. The symptom score and lung function at 4 weeks later after education were significantly improved (P=0.000). The turbuhaler users all performed fair to good on each step. The symptom score was significantly improved (P<0.005), but the lung function was not difference. Over 95% of the users of a metered dose inhaler with a spacer performed moderate to good on each step. The symptom score and lung function were significantly improved (P<0.05). Conclusion: The structured, detailed education on inhaler devices by trained specialists was very important for performing correct inhalation therapy to control asthma, and repeated education might be also necessary.

Purpose: This study was performed to compare the clinical features of pediatric patients who were diagnosed with influenza A (H1N1) or seasonal influenza A and B during 2009 and 2010 at a single institution. Methods: Among children who visited the Dong-A University Hospital with fever (>37.8℃) and acute respiratory symptoms from September 2009 to February 2010, 1,004 children who were diagnosed with influenza A (H1N1) or seasonal influenza A and B by reverse transcription-polymerase chain reaction (RT-PCR) were enrolled. Monthly incidence, fever duration before diagnosis, symptoms (fever, cough, rhinorrhea, sore throat, headache, vomiting, abdominal pain, diarrhea, seizure, and dyspnea) and signs (rales, wheezing) were reviewed retrospectively in each group based on medical records. Results: Influenza A (H1N1) was detected in 944 patients (94.0%), followed by seasonal influenza A in 42 (4.2%) and seasonal influenza B in 8 (1.8%). The positive rate of influenza infection was highest in November 2009 (n=557, 55.5%). Mean duration of fever before RT-PCR was 1.6 days (range, 1.5 to 1.8 days). Except fever, cough was the most common symptom (n=792, 78.9%), followed by rhinorrhea in 407 patients (40.5%). Rales and wheezing were detected in 16 patients (1.6%) and 19 (1.9%), respectively. Significant differences were observed for the number of patients who had cough, headache, vomiting, and wheezing among the three groups (P<0.05). Conclusion: Although the incidence of cough, headache, vomiting, and wheezing differed significantly among the three groups, the number of patients in each group was too different to compare the results.

Purpose: The aim of this study was to investigate the differences in behavioral characteristics and parental stress between allergic and nonallergic elementary school children. Methods: Ninety-one elementary school children who had allergic disease were enrolled (asthma, n=27; allergic rhinitis, n=35; combined, n=29). Also one hundred six nonallergic elementary school children were enrolled for the control group. The Korean Child Behavior Check List (K-CBCL) and Korean Parenting Stress Index-Short Form (K-PSI-SF) were completed by their mothers. Results: According to the analysis of K-CBCL, the score for Internalizing, anxious/depressed and somatic complaints were significantly higher in the combined group than in the control group. The score for Diagnostic and Statistical Manual of Mental Disorders (DSM)-affective problems in the combined group and DSM-somatic problems were significantly higher in the asthma group than in the control group. According to the analysis of K-PSI-SF, the score for parental distress was significantly higher in the allergic rhinitis group than in the control group. The scores for behavioral problems and parental stress were significantly correlated to allergic disease groups. Conclusion: Behavioral problems and parental stress were significantly associated with asthma and allergic rhinitis. The results of this study suggest the importance of psychosocial support for mothers and children with allergic diseases. (Allergy Asthma Respir Dis 2016;4:205-211)

문태영 ( Tae Young Moon ),손지환 ( Ji Hwan Son ),윤현진 ( Hyun Jin Yun ),홍희경 ( Hee Kyoung Hong ),최광호 ( Kwang Ho Choi ),김정수 ( Jung Soo Kim ),김정화 ( Joung Hwa Kim ) 한국분무공학회 2014 한국액체미립화학회지 Vol.19 No.3

In this study, characteristics of gaseous pollutants and particulate matter were investigated on the condition of DPF regeneration and normal DPF condition. THC, CO, CO2, NOx, and CH4 were analyzed by MEXA-7200H and CVS-7100 respectively. Particulate Matter (PM) was measured by difference in weight of Membrane filter. Particle Number (PN) was measured by CPC analyzer. And Sulfate, Nitrate, Organic were measured by Aerosol Mass Spectrometer (AMS). As a result, gaseous pollutants and particulate matter were detected in higher concentration during DPF regeneration than normal DPF condition. And the PN increased by 94%, the fuel consumption was reduced by 29% on DPF generation process. Sulfate, Nitrate and Organic were undetectable level during normal DPF condition. But the highest concentration of Sulfate, Nitrate and Organic were measured as 100 μg/m3, 20 μg/m3 and 15 μg/m3 respectively on DPF regeneration condition. VOCs concentrations (Benzene, Toluene, Ethylbenzene, Xylene) were analyzed by using PTR-MS. Benzene and Toluene emission have little or no change depending on DPF regeneration. But the Ethylbenzene and Xylene have comparatively low emissions on DPF regeneration.

김형수 ( Hyung Su Kim ),이주희 ( Ju Hee Lee ),윤현진 ( Hyun Jin Yun ),김병권 ( Byoung Gwon Kim ),정진아 ( Jin A Jung ) 대한소아알레르기호흡기학회(구 대한소아알레르기 및 호흡기학회) 2010 소아알레르기 및 호흡기학회지 Vol.20 No.3

목적: 천식과 부비동염은 염증성 반응이라는 동일한 병리학적 현상이 호흡기계 내의 서로 다른 표적기관에서 나타나는 것일 뿐 근본적으로 하나의 연계된 기도질환이라고 알려져 있다. 본 연구에서는 부비동염과 천식 사이의 혈청학적 검사를 통해 주된 면역반응의 차이점과 임상 양상을 비교해 보고자 하였다. 방법: 2005년 3월부터 2008년 2월까지 동아대학교 의료원 소아청소년과와 부산의료원 소아청소년과 알레르기센터를 방문한 118명의 학동기 환자들을 대상으로 말초 혈액 호산구수 총 IgE, 7종 흡입항원 (유럽 집먼지진드기 아메리카 집먼지진드기, Alternaria 바퀴벌레 고양이, 개, 화분) 에 대한 특이 IgE와 IL-4, IFN-γ를 측정하였다. 이들은 부비동염으로 진단된 환자31명 (A군), 천식으로 진단된 환자 36명 (B군), 천식과 부비동염이 병발된 환자 51명(C군)으로 나누어 결과들을 비교하였다. 결과: 말초 혈액 호산구수와 총 IgE는 A군에서 현저하게 낮았다. 흡입항원에 대한 피부 단자 시험의 경우 유럽 집먼지진드기와 아메리카 집먼지진드기에 대한 양성률은 B군과 C군이 비슷하였으나, Alternaria와 개에 대한 양성률은 C군에서 고양이와 화분에 대한 양성률은 B군에서 높게 나왔다. C군에서 임상증상은 골고루 나타나면서 알레르기 비염의 동반률은 B군과 비슷하였으며 기관지 유발 검사 민감도는 높게 나왔다. 혈청IL-4는 C군와 C군이 A군보다 의미있게 높게 나왔으며, (P<0.001) IFN-γ의 경우 A군이 <0.001) C군보다 의미있게 높게 나왔다. 결론: 기관지 천식에서는 Th2 면역반응이 부비동염에서는 Th1 면역반응이 주된 역할을 하지만 두 질환의 동반유무에 따라 면역반응이 다양하게 관찰되어진다. Purpose: Bronchial asthma and sinusitis have been grouped together and classified as one airway-related disease, with the same underlying inflammatory etiology. Through serological examination,we ascertained a difference in the immune response between bronchial asthma and sinusitis.Methods: We measured the peripheral blood eosinophil count, total IgE and specific IgE to 7aeroallergens ( Dermatophagoides pteronyssinus, Dermatophagoides farinae, Alternaria, cockroach,cat, dog and pollen), and interleukin (IL)-4 and interferon (IFN)- of 118 school aged patients γ-who visited Dong A University Medical Center and Busan Medical Center from March 2005 to February 2008. We divided these patients into 31 diagnosed with sinusitis (Group A), 36 diagnosed with bronchial asthma (Group B), and 51 diagnosed with both sinusitis and asthma (Group C).Results: The peripheral blood eosinophil count and total IgE were markedly lower in group A. Dermatophagoides pteryonyssinus and Dermatophagoides farinaehad higher sensitization rates than other aeroallergens in groups B and C. The sensitization rates to Alternaria and dog were higher in group C than in group B, and the sensitization rates to cat and pollen were higher in group B than in group C. In group C, clinical symptoms occurred evenly and allergic rhinitis was concurrent, similar to group B; however, the sensitivity of the bronchial provocation test was higher than in group B. Serum IL 4 in group B and C were significantly higher than in group A (P<0.001), and serum IFN was significantly higher in group A than in group C (P<0.027).Conclusion : Bronchial asthma was primarily related to IL-4 and Th2 cytokines, while sinusitis was primarily related to IFN and Th1 cytokines. According to the degree of ssociation between the 2 diseases, various immune responses were observed.
