And we have found that the effect of Dong-si acupuncture therapy is faster than the other.

코로나19 대응 거버넌스의 성공 요인에 관한 탐색적 연구: 성과중심적 거버넌스 모형을 활용하여

윤기웅(Yoon, Ki-Woong),공동성(Kong, Dong-Sung) 한국정부학회 2020 한국행정논집 Vol.32 No.3

본 연구는 코로나19 방역 모범국이라는 평가를 받는 한국의 코로나19 대응 전략 및 성공 요인을 살펴보는 데 그 목적이 있다. 코로나19 감염병은 사회재난 중 하나로 정부가 중심이 되는 공공거버넌스의 영역이라고 볼 수 있다. 따라서 본 연구는 공공거버넌스 유형 중 하나인 성과중심적 거버넌스 모형을 활용하여 코로나19 방역의 성과(확진자와 사망자의 통제 가능 여부)에 영향을 미치는 요인들을 탐색적으로 분석한다. 분석결과 거버넌스 맥락, 정권, 행정적 준비단계, 성과향상 실행메커니즘에 포함되는 다양한 요인들이 한국의 코로나19 방역의 성과에 이바지한 것으로 나타났다. 구체적으로 살펴보면, 첫째, 거버넌스 맥락 차원에서 2015년 메르스 대응실패 이후 이루어진 법령 개정, 중앙집권체계, 정보통신기술발달 등 방역 활동에 우호적인 외부환경 요소들이 방역의 성과향상에 기여하였다. 둘째, 정권 차원에서 방역당국에 대한 대통령의 적극적 지원과 범정부적 조직/인사/예산지원은 방역당국이 효과적으로 방역에 집중할 수 있도록 하는 밑거름이 되었다. 셋째, 행정적 준비단계 차원에서 구체적으로 마련된 표준운영절차(SOP)와 담당자에 대한 교육/훈련을 통한 역량 강화는 방역 일선 담당자들의 일사불란한 대처를 가능하게 했다. 넷째, 성과향상 실행메커니즘 차원에서 방역당국은 주어진 상황 및 여건에 맞춘 적절한 대비를 하였을 뿐만 아니라 신속한 진단검사 및 역학조사를 통해 확진자를 조기 발견하여 적시에 감염병 확산을 차단할 수 있었다. 결론적으로 피해복구 단계를 제외한 예방, 대비, 대응 단계에서 적절한 조치가 이루어졌고, 이로 인해 비록 미흡한 점이 일부 있기는 하나 한국의 코로나19 방역이 어느 정도 성공적으로 작동하였다고 볼 수 있다. South Korea is being evaluated by global media and experts for its successful response to coronavirus disease 2019 (COVID-19). The purpose of this study is to examine the Korean government’s response strategy and success factors for COVID-19 using the performancebased/managerial governance model which was presented by Kong & Yoon(2018b). It found that various factors, such as governance context, governance regime, pre-governance and execution mechanisms, all together contributed to South Korea’s success in responding to COVID-19. These findings can be considered to be of theoretical significance in that they expanded the applicability of the public governance model proposed by Kong & Yoon. In addition, the case of South Korea, which has harmoniously achieved the two conflicting goals of controlling infectious disease and minimizing economic damage, provides many practical implications for how other countries should cope in the future.

급성전골수성백혈병에서 백혈구성분채집술에 이은 치명적인 뇌출혈 2예

The aim of this study is to report 2 cases of acute promyelocytic leukemia who died from intracranial hemorrhage following leukapheresis and to provide proper preventive measures against hemorrhage following leukapheresis. From 1994 to 1997, a total of twenty-six patients with leukemia underwent leukapheresis to control hyperleukocytosis at Ajou University Hospital. Two patients with acute promyelocytic leukemia received all-trans retinoic acid but developed drug-induced hyperleukocytosis. Shortly after leukapheresis, they died from intracranial hemorrhage. The risk factors for fatal hemorrhage are thought to be coexisting disseminated intravascular coagulation(DIC), thrombocytopenia aggravated by leukapheresis, exacerbated coagulopathy related to mechanical trauma through leukapheresis and the excess use of citrate during leukapheresis. To reduce the risk of the bleeding associated with leukapheresis, it is necessary to replace platelet sufficiently before and after leukapheresis and to give calcium to correct coagulopathy induced by excess citrate which is used as anticoagulant as well as the correction of disseminated intravascular coagulation.

Evaluation of the Efficacy and Safety of DA-9601 versus Its New Formulation, DA-5204, in Patients with Gastritis: Phase III, Randomized, Double-Blind, Non-Inferiority Study

Choi, Yoon Jin,Lee, Dong Ho,Choi, Myung-Gyu,Lee, Sung Joon,Kim, Sung Kook,Song, Geun Am,Rhee, Poong-Lyul,Jung, Hwoon-Yong,Kang, Dae-Hwan,Lee, Yong Chan,Lee, Si Hyung,Choi, Suck Chei,Shim, Ki-Nam,Seol, KOREAN ACADEMY OF MEDICAL SCIENCE 2017 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.32 No.11

<P>This study compared the efficacy of DA-9601 (Dong-A ST Co., Seoul, Korea) and its new formulation, DA-5204 (Dong-A ST Co.), for treating erosive gastritis. This phase III, randomized, multicenter, double-blind, non-inferiority trial randomly assigned 434 patients with endoscopically proven gastric mucosal erosions into two groups: DA-9601 3 times daily or DA-5,204 twice daily for 2 weeks. The final analysis included 421 patients (DA-5204, 209; DA-9601, 212). The primary endpoint (rate of effective gastric erosion healing) and secondary endpoints (cure rate of endoscopic erosion and gastrointestinal [GI] symptom relief) were assessed using endoscopy after the treatment. Drug-related adverse events (AEs), including GI symptoms, were also compared. At week 2, gastric healing rates with DA-5204 and DA-9601 were 42.1% (88/209) and 42.5% (90/212), respectively. The difference between the groups was −0.4% (95% confidence interval, −9.8% to 9.1%), which was above the non-inferiority margin of −14%. The cure rate of gastric erosion in both groups was 37.3%. The improvement rates of GI symptoms with DA-5204 and DA-9601 were 40.4% and 40.8%, respectively. There were no statistically significant differences between the two groups in both secondary endpoints. AEs were reported in 18 (8.4%) patients in the DA-5204 group and 19 (8.8%) in the DA-9601 group. Rates of AE were not different between the two groups. No serious AE or adverse drug reaction (ADR) occurred. These results demonstrate the non-inferiority of DA-5204 compared to DA-9601. DA-5204 is as effective as DA-9601 in the treatment of erosive gastritis. Registered randomized clinical trial at ClinicalTrials.gov (NCT02282670)</P>

이민수,김용구,김영훈,연병길,오병훈,윤도준,윤진상,이철,정희연,강병조,김광수,김동언,김명정,김상훈,김희철,나철,노승호,민경준,박기창,박두병,백기청,백인호,손봉기,손진욱,양병환,양창국,우행원,이정호,이종범,이홍식,임기영,전태연,정영조,정영철,정인과,정인원,지익성,채정호,한상익,한선호,한진희,서광윤 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.1

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Java applets are downloaded from web server through internet and executed in Java Virtual Machine of clients' browser. Before execution of java applets, JVM checks bytecode program with bytecode verifier and performs runtime tests with interpreter. However, these tests will not protect against undesirable runtime behavior of java applets, such as denial of service attack, email forging attack, URL spoofing attack, or annoying sound attack. In order to protect malicious applets, a technique used in this paper is java bytecode modification. This technique is used to restrict applet behavior or insert code appropriate to profiling or other monitoring efforts. Java byte modification is divided into two general forms, class-level modification involving subclassing non-final classes and method-level modification used when control over objects from final classes or interface. This paper showed that malicious applets are controlled by java bytecode modification using proxy server. This implementation does not require any changes in the web sever, JVM or web browser.

In order to observe hydrological characteristics in the Gulf of Yoeng-il, measurements of water temperature have been carried out from February to August 1983, and from August 1985 to December 1986. Surface water temperatures are closely linked to air temperature and solar-radiation for all littoral stations. Seasonal and annual variations of all horizontal stations are very similar to one another. Vertical variations of water temperatures for the stations located along the central-line of the Gulf are characteristic (and observed) as thermoclines and thermal stratification in the hottest summer-time (August). It is interesting to note that water column temperature of July and September are rather warmer than August, on account of a cold water mass coming from NE direction. For example, surface temperature in June 1982 was above 19℃, but the water below a depth of about 30m drastically drops to 4℃. It is indicative of invasion of water mass from cold current or deep sea.

AE 신호와 재료의 기계적 물성과의 관계를 정량적으로 제시할 수 있는 방법을 개발하였다. 재료의 여러 가지 기계적 성질들 중 피로균열 거동에 관련된 응력확대계수를 중심으로 AE 신호와 같은 다변량 데이터의 처리에 많이 사용되고 있는 주성분 회귀분석과 비선형적 문제 해결에 적합한 신경회로망 기법을 이용하였다. 이를 위하여 강교량 부재인 SWS490B 강에 대한 피로균열전파 실험을 수행하였으며 표준 CT 시편에 대한 피로균열진전 시 발생하는 AE 신호의 각 변수와 응력확대계수와의 관계를 고찰하였다. 통계분석 방법인 변수선택법을 적용한 결과 AE 카운트(RC), 에너지(EN), 신호지속시간(ED)의 각각에 대한 유의성이 높은 것으로 나타났으나 전반적으로 전체 AE 변수를 모두 이용할 경우 통계적 유의성이 높은 것으로 나타났다. 부재의 반복하중 시 발생하는 피로균열진전을 정량적으로 도출할 수 있는 응력확대계수 추정모델을 개발하고 평가하였다. 미지 시료에 대하여 개발된 모델의 응력확대계수 예측 성능을 분석한 결과 주성분 회귀모델과 인공신경망 모델 모두 우수한 예측성능을 나타내었으나 전반적으로 인공신경망 모델이 주성분 회귀모델보다 다소 양호한 것으로 분석되었 다. The aim of this study is to develop the methodology which enables to identify the mechanical properties of element such as stress intensity factor by using the AE parameters. Considering the multivariate and nonlinear properties of AE parameters such as ringdown count, rise time, energy, event duration and peak amplitude from fatigue cracks of machine element, the principal component regression(PCR) and artificial neural network(ANN) models for the estimation of stress intensity factor were developed and validated. The AE parameters were found to be very significant to estimate the stress intensity factor. Since the statistical values including correlation coefficients, standard error of calibration, standard error of prediction and bias were stable, the PCR and ANN models for stress intensity factor were very robust. The performance of ANN model for unknown data of stress intensity factor was getter than that of PCR model.

To investigate the inhibitory effect of soybean and Korean traditional fermented soybean products on the chemically induced mutagenesis, we extracted soybean, Kanjang, Doenjang, Kochujang, and Chonkukjang with water, methanol and hexane. Inhibitory effect of extracts was assayed by the SOS chromotest using Escherichia coli PQ37 as a test strain. 4-nitroquinoline-1-oxide(4NQO), N-methyl-N'-nitro-N-nitrosoguanidine(MNNG), and aflatoxin B_1(AFB_1) were used as mutagens. Methanol extracts showed relatively higher inhibitory effect than water and hexane extracts. Methanol extracts of soybea, Doenjang, Kochujang, and Chongkukjang showed inhibitory effect of 68.4, 96.3, 17.5, and 100.9%, against MNNG, and 28.6, 109.1, 41.3, and 101.8% against AFB_1., respectively. Doenjang methanol extract showed inhibitory effect of 51.0, 96.3, and 109.1% against 4NQO, MNNG, and AFB_1. Inhibitory effect of heat-treated Doenjang and Chongkukjang methanol extracts on the mutagenicity of MNNG and AFB_1 was remained over 95% of the inhibitory effect of heat-untreated extracts, demonstrating the heat stability of the potent antimutagenic activity.
