이지은(Lee, Ji-Eun), 이재완(Lee, Jae-Wan) 본 연구의 목적은'삶의 질'에 대한 지역주민의 인식을 유형화하고 분석하는 데 있다. 지역주민의 삶의 질에 관한 주관적 인식을 분석하기 위해 Q방법론을 활용하였다. 지역주민을 대상으로 한 인터뷰 및 선행연구 검토를 통해 Q진술문을 작성하였고, P샘플은 서울시에 거주하고 있는 지역주민 40명을 대상으로 하였다. 분석 결과, 삶의 질에 대한 주민인식은 ① 기본적 요건 지향, ② 물질적 요건 지향, ③ 비물질적 요건 지향으로 유형화되는 것으로 나타났다. 본 연구는 삶의 질에 관한 인식이 지역주민마다 다를 수 있으므로, 지방자치 수준에서 숙의민주주의를 실현할 수 있는 공론의 장을 마련할 필요가 있다는 점을 시사한다. 지방정부가 지역주민들의 삶의 질을 향상시키는 정책을 수립할 때 다양한 주민들의 인식과 의견이 반영될 수 있도록 하여야 할 것이다. The objective of this study is to classify and analyze citizens' perceptions on 'quality of life'. In order to examine quality of life as perceived by citizens, Q-methodology was used. A set of Q-statements was constructed with reference to field interviews of citizens and literature review of the precedent study, and it was rated by 40 citizens residing in Seoul. The results of this study revealed that citizens' perceptions of quality of life could be classified in terms of three perspectives: 1. Basic conditions orientation, 2. Material conditions orientation, and 3. Non-material conditions orientation. Based on the analysis results, this study suggests that as citizens' perceptions of quality of life can be diverse, there is a need to develop a public sphere where deliberative democracy would be realized and advanced at local government level. By creating and developing public spheres, local governments would be able to take citizens' perceptions and opinions into account better when establishing policies for improving citizens' quality of life.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

기능성 위장관장애 환자의 자율신경계기능과 음-양(陰陽)체질 특성에 관한 연구

이정호,송지영,황의완,정두훈,김영미 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.4

연구목적 : 기질적 원인이 없이 장기간 소화장애 및 복통이 지속되는 기능성 위장관 장애 환자를 대상으로 하여, 음양체질의 특성이 위장관을 조절하는 자율신경계 기능 이상과 관련되는지를 알아보기 위하여, 사상체질 특성에 따른 자율신경계 기능의 차이유무를 측정해 보고자 하였다. 이로써 이들 환자에서 보이는 자율신경계 기능의 불균형 상태가 한의학에서 말하는 음양(陰陽)이론으로 설명할 수 있을지 알아 보고자 하였다. 그리고 만일 이러한 설명이 가능하게 되면 향후 기능성 위장관 장애 환자에 대한 음양이론에 입각한 치료의 이론적 배경이 될 것으로 기대하였다. 방 법 : 기능성 위장관 장애 환자 27명과 대조군으로서 위장관 증상 이외의 증상을 가진 신체형 장애 환자(이하 기타 신체형 장애) 28명과 건강 대조군 26명을 조사 대상으로 하였다. 이들에게 사상체질(四象體質)분류검사를 이용하여 소음 체질과 기타 체질군으로 나누고, 자율신경 기능검사를 실시하여 체질에 따른 자율신경계 기능을 비교해 보았다. 결 과 : 기능성 위장관 환자군에서 소음체질이 의미있게 많은 빈도를 차지하지는 않았으며, 기능성 위장관 장애군과 기타 신체형 장애군과의 비교에서 자율신경 기능의 차이는 없었다. 이로서 비기질성 기능 장애의 하나인 기능성 위장 장애에서 체질 특성과 부교감신경계 기능 저하와는 관련성은 거의 없다고 추정된다. 단지 기능성 위장 장애군과 기타 신체형 장애군을 합한 신체형 장애 환자군에서는 건강 대조군에 비하여 소음체질의 빈도가 높았으며 부교감신경 기능이 의미있게 낮은 소견을 보였다. 결 론 : 비기질성 기능 장애인 기능성 위장관 장애에서는 한의학에서의 음양가설이라는 일원론에 입각한 이분법적인 개념이 자율신경계의 교감, 부교감 신경계 기능과 일치하는 부분은 적은 것으로 추정된다. 기능성 위장관 장애를 대상으로 해서 앞으로는 음양의 체질이라는 포괄적인 개념보다는 확실한 증상 몇 개 중심으로 하는 좀 더 세분화된 부분으로부터 접근해 볼 필요가 있으리라 사료된다. Objectives : It was revealed that autonomic dysfunction especially decreased parasympathetic functions, seems to be one of the major etiological factors in functional gastrointestinal disorders(FGID). The physiological characteristics of sympathetic and parasympathetic functions are externally similar to the features of Yin and Yang based on oriental medicine theory. And it was also revealed that gastrointestinal symptoms are prevalent in Lesser Yin con-stitutional type(少陰) originated from four types of constitution shown in Sasang constitutional theory(四象醫學). If we obtain the findings on the similarities or compatibilities between autonomic nervous functions and physical constitutional features in functional gastrointestinal disorders, we could apply various oriental treatment modalities to the patients with functional disorders, especially according to Yin-Yang constitutional concept. Methods : We investigated the correlations between characteristics of physical constitution (Yin and Yang) and imbalance of the autonomic functions in patients with FGID. Subjects consisted with three groups : 27 patients with FGID (including irritable bowel syndrome, functional dyspepsia, functional abdominal pain syndrome according to the Rome criteria), 28 patients with somatoform disorders who had symptoms other than abdominal symptoms(other somatoform disorders), and 26 normal healthy controls. Characteristics of constitutions were evaluated and divided into two major groups, i.e., Lesser Yin constitution and other constitutions(Greater Yin & Yang and Lesser Yang included) according to the Je-Ma Lee's Classification Questionnaire for Four Constitutional Types(Song et al. 1993). For evaluating the autonomic functions, three parasympathetic functions and two sympathetic functions were measured. Levels of anxiety and depression were also evaluated to be used as a covariant controlling the autonomic functions. Results : 1) FGID group showed significantly lower parasympathetic functions compared to healthy controls, however, there was no differences between FGID and other somatoform disorder groups. 2) Lesser Yin constitutional type was not so prevalent in FGID group. 3) When FGID and other somatoform disorder groups were combined and compared with normal healthy controls, the former group showed significantly lower parasympathetic functions than the latter group. Conclusions : According to these results, Lesser Yin constitutional type do not seem to be closely related with FGID. However, it was suggested that decreased parasympathetic functions were partly associated with this group. We could not find any correlations or compatibilities between two constitutional characteristics and autonomic dysfunction in FGID. This means that functional symptoms of FGID when those were deducted as Yin and Yang characteristics based on oriental medicine could not be understood as two oppositional and co-operative functions such as autonomic functions. Further research with more restricted symptoms selected in the functional disorders and with other physiological cues applied would be needed.

혈액질환 가운데 결핵 발생이 증가한다고 알려진 것은 호지킨 림프종을 포함한 림프증식성질환 그리고 모양세포성 백혈병 등이 있다. 또한 동종 골수이식을 받은 환자에서도 결핵은 증가한다고 알려져있다. Kaplan 등은 골수구성 백혈병 환자에서 결핵 발생이 증가한다고 보고하였다. 그러나 골수구성 백혈병 환자에서 결핵의 발생이 증가하는 이유에 대해서는 아직까지 정확하게 밝혀지지 않았다. 저자들이 2년 동안 후향적으로 조사한 180명의 성인 골수구성 백혈병 환자들 가운데 결핵이 발생한 환자는 4명이었고, 발생 부위는 모두 림프절이었다. 결핵은 골수구성 백혈병의 특정 아형에만 국한되어 발생하지 않았지만, 50%에서 FAB 분류에 의한 M4였다. 림프절이 종대된 골수구성 백혈병 환자에서 특히, 결핵의 유병율이 높은 나라에서는 결핵성 림프절염도 감별진단에 포함시켜야 한다. During the neutropenic phase, leukemia patients receiving chemotherapy are prone to bacterial and, fungal infections; occasionally mycobacterial, viral and protozoal organisms may also cause infections. Mycobacterium tuberculosis infection was reported very rarely in these patients. This report describes four patients with M. tuberculosis infection identified from 185 adult patients who were diagnosed myelogenous leukemia between January 2003, and December 2004. There was no patient with M. tuberculosis infection from 44 lymphoid leukemia and 11 acute biphenotypic leukemia patients. Sites of infection were all lymph nodes. Three among four patients were presented with lymphadenopathy at initial diagnosis of leukemia, and the other one presented with lymphadenopathy after induction chemotherapy. There was no patient presented with lymphadenopathy during the neutropenic phase. Tuberculous lymphadenitis was presented in a patient with three acute myelogenous leukemia (FAB class 2 M4, 1 M2) and a chronic myelogenous leukemia, accelerated phase. An acute myelogenous leukemia patient had a leukemic cell and tubercle bacilli in the same lymph node. Tuberculosis should also be included as a differential diagnosis in myelogenous leukemia patient with lymphadenopathy, especially in the countries in which the disease is endemic.

개선된 중성염 전해공정을 이용한 모의 방사성금속폐기물의 제염

이지훈,육완이,양호연,하종현 대한방사선 방어학회 2002 방사선방어학회지 Vol.27 No.2

원자력발전소에서 주로 발생되는 금속폐기물인 탄소강을 중성염전해질인 1.7M의 황산나트륨(Na₂SO₄)과 질산나트륨(NaNO₃)을 이용하여 기존전해제염과 개선된 전해제염공정의 비교실험을 수행하였다. 양극은 인코넬, 음극은 티타늄으로 하여 상온에서 1시간동안 반응시켜 금속폐기물 모재의 weight loss, 두께변화, 전해질 내 침전물농도, SEM을 이용하여 제염전후의 금속폐기물 표면의 형상을 분석하였다. 실험결과 개선된 전해제염 적용시 전해질 종류별 전류밀도 변화에 따른 실험에서는 전류밀도가 0.1∼0.6A/cm²으로 증가함에 따라 1.7M의 황산나트륨 적용시 금속폐기물 모재의 두께변화는 0.48±0.005∼67.7±0.02um, 1.7M의 질산나트륨 적용시에는 0.06±0.005∼17.7±0.05로 나타나 같은 전류밀도에서 황산나트륨 적용시 금속폐기물 모재의 표면 제염효율이 더욱 높은 양상을 보였다. 또한 전류밀도 0.3 A/cm² 및 1.7M의 황산나트륨의 조건에서 개선된 전해제염 적용 시 9.8±0.01um의 금속폐기물 두께변화를 보여 기존전해제염 적용시인 3.7±0.03um의 금속폐기물 두께변화보다 2배 이상의 표면 제염효과를 보였다. Conventional and modified electrolytic decontamination experiment were performed in the 1.7 M solution of sodium sulfate and sodium nitrate for decontamination of carbon steel as the simulated metal wastes which have been produced in large amounts from nuclear power plants. Anode and cathode were used as inconel and titanium respectively. The reaction time and temperature were 1 hr and 25℃. The analyses were performed of the characteristics such as weight loss and thickness change of metal waste, suspended solid in electrolyte and SEM observation. In modified electrolyte decontamination system with increased current density ranged from 0.1 to 0.6 A/cm², the metal waste showed thickness changes of 0.48±0.005 to 67.7±0.02um in 1.7 M sodium sulfate and those of 0.06±0.005 to 17.7±0.05um in sodium nitrate. Metal waste in modified electrolyte decontamination system showed the thickness change of 9.8±0.01um while it reacted up to 3.7±0.03um in conventional system with 0.3 A/cm² of current density and 1.7 M sodium sulfate. Decontamination efficiencies of modified electrolytic process are much higher than that of conventional electrolytic process when both are applied to metal waste.

이지영,이상형,오창완,한대희 대한신경외과학회 1995 Journal of Korean neurosurgical society Vol.24 No.10

In an effort to understand the clinical symptomatology of intracranial arteriovenous malformations(AVMs), to determine their best management policy, and to accumulate our clinical data, a retrospective clinical analysis of 187 patients with intracranial AVMs which were diagnosed by neuroradiological studies or histopathologically was performed during the period from January 1983 to May 1994. Among the 187 patients of whom four patient with dural type AVM and eight referral Patients were excluded, 120 patients were treated surgically and the other 55 patients, managed conservatively. The outcome of all patients were analysed and their post-ictal status was followed for an average of 31.7 months. The results were as follows : 1) The peak incidence of intracranial AVMs was in the third decade(mean age 28.9 years) followed by the second decade and the fourth decade. The male to female ratio was 1.9:1. 2) The presenting symptoms were mainly Intracranial hemorrhage(50.3%), seizure(33.2%) and headache(9.6%). Among the types of intracranial hemorrhage, intracerebral hematoma was the most frequent, and of the seizure type, generalized seizure was seen most frequently. 3) The locations of intracranial AVMs were hemispheric(78%), deep seated(14%), posterior fossa(6%), and dural(2%). 4) The presenting symptoms of intracranial hemorrhage and seizure depended significantly on the size of the AVM; 71% of small AVMs(<3cm) presented with hemorrhage, while 53% of large ones(> 6cm) presented with seizure. 5) The rate of rebleeding was 21%(20 of 94) and the associated mortality rate was 5%(1 of 20). 6) Concomitant aneurysms were found in 14 cases(7.5%). 7) In surgically treated cases, the mortality rate was 2.5% and its morbidity rate, 26.7%. In conservatively treated cases, the mortality rate was 3.6% and its morbidity rate, 27.3%. 8) The clinical outcome of children was similar to that of adults. 9) Patients with seizures showed a bitter outcome than those with hemorrhages and the clinical outcome did not depend on the methods of treatments in either patients with hemorrhages or those with seizures. 10) With respect to the Spetzler-Martin grade, the surgical outcome improved significantly as the grade became lower. 11) There was a marked tendency for postoperative neurological deficits to improve with time during the mean follow-up period(31.7 months). As such, early morbidity rate was 50% and late morbidity rate decreased to 26.7%. 12) Preoperative embolization was effective for a safe surgical removal of the AVMs with a poor grade. 13) Of the patients who did not have seizures before surgery, 7.9%(6/76) had late seizures in whom all were not well controlled with medication. Of the patients who had seizures before surgery, 82.9%(29/35) were either cured or controlled with medication.

허지안,전혜선,박선희,최수미,김시현,이동건,최정현,유진홍,신완식 대한감염학회 2006 감염과 화학요법 Vol.38 No.6

배경 : Penicillin 내성 폐렴알균이 증가하는 지역에서 대안 중의 하나로 사용되는 ceftriaxone (CTR)의 적절한 용법, 용량을 파악하는 것이 중요하다. 본 연구는 임상에서 분리된 폐렴알균을 대상으로 시험관내 약역학 감염모델을 이용하여 알부민이 첨가된 경우와 첨가되지 않은 경우 CTR의 일일 1회 요법의 효과를 비교해 보고자 하였다. 재료 및 방법 : Penicillin 감수성(SM24), 중간내성(SM47), 내성(SM60)주를 대상으로 2-구획 시험관내 약역학 감염모델을 적용하였다. CTR 주입은 2 g씩 24시간마다로 사람의 약동학을 모의하였다. 알부민은 모델에서 4g/ dL가 유지되도록 하였다. 살균효과는 0, 2, 4, 6, 24, 30, 48시간째 집락수 변화로 측정하였다. 결과 : 모든 균주에서 알부민이 첨가되지 않은 경우 6시간 이내에 살균력이 관찰되었다. 최저억제농도 및 알부민 첨가유무에 관계없이 3주 모두 24시간째 살균력이 관찰되었고, 48시간째는 모두 측정한계 이하의 집락수로 감소하였다. 전 실험과정에서 CTR에 대한 내성주는 출현하지 않았다. 결론 : CTR의 일일 1회 요법은 알부민이 첨가되었을 때, 감수성, 중간내성, 내성주 모두에서 살균력 발현이 지연되었으나 최종효과는 알부민이 없을 때와 다르지 않았다. 앞으로 알부민 결합효과와 관련된 기초적인 추가 연구가 필요할 것으로 생각된다. Background : During the era of increasing penicillin resistant Streptococcus pneumoniae, it is important to have knowledge about adequate dosage and dosing interval of ceftriaxone (CTR). We examined efficacies of once-daily CTR and compared results in an in vitro pharmacodynamic infection model (IVPDIM) supplemented with albumin and those without albumin. Methods : Using three clinically isolated S. pneumoniae that were susceptible (SM24), intermediate (SM47) and resistant (SM60) against CTR, we utilized a two-compartment IVPDIM. CTR 2 g was administered intravenously every 24 h. Human albumin was added with concentration of 4 g/dL. Samples were removed at multiple time points over a 48-h period to determine the colony counts. Results : In SM24 and SM60, bactericidal effects were observed within 6 hours in groups without albumin. The number of colonies during 1st 6 hours were more decreased in albumin-free groups than in albumin-supplemented groups (P<0.05). In SM47, similar results were found during 1st 6 hours (P=0.03). But, regrowth was observed in albumin supplemented group at 30 h. Irrespective of results of minimal inhibitory concentrations and albumin supplementation, bactericidal effects were shown at 24 h in all 3 strains. All groups were decreased below the detection limit at 48 h. Development of resistance was not detected throughout the entire study period in either strain. Conclusions : Although extents of killing in albumin supplemented broth of once-daily CTR dosing were delayed in all 3 strains compared with those of albumin free broth, final efficacies were not different between the two groups.

Polishing process of Si wafer is a momentous stage during the semiconductor process of manufacture. A surface condition of fabricated Si wafer influences in inferiority rate of final semiconductor products. Among the major factors of wafer polishing process, polishing pad surface roughness and a degree of plastic deformation have an effect of polished wafer surface quality. A pad should be maintained its machining ability during the polishing process. However, capability of pad is reduced when polishing time is increased. Dressing and conditioning process on a polishing pad is needed for the preservation of pad surface condition. In this study, an influence of dressing defect was investigated during the Si wafer polishing process. When the dressing process was not supplied, pad surface quality was analyzed by using SEM images, pad surface roughness variation and temperature variation on the polishing pad. And the relationship between Si wafer polishing pad lifetime and dressing defect was evaluated.
