Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

<P>Polypropylene (PP)/carbon black (CB)-alkylated graphene oxide (AGO) hybrid nanocomposites were prepared via solution process and the synergistic effects of AGO on the properties of the PP/CB nanocomposites were investigated. AGO at a content of only 0.2 wt% formed an overlapped network structure in the PP matrix and affected the electrical, thermal and mechanical properties of the PP/CB nanocomposites. Specifically, PP/CB (5 wt%)-AGO (0.2 wt%) nanocomposites exhibited an electrical percolation threshold at lower CB contents than the PP/CB nanocomposites did, and the sheet resistance was decreased to 2.3 x 10(7) omega/sq. The thermal degradation temperature and recrystallization temperature of the PP/CB (10 wt%) nanocomposites were increased by 11.3 and 1.6 degrees C, respectively, by the addition of 0.2 wt% AGO. In addition, the Young's modulus of the PP/CB (10 wt%) nanocomposite was increased from 438.1 to 540.1 MPa.</P>

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

추상회화의 실존적 수용 과정에 관한 연구 -본인의 작업을 중심으로-

정윤영 ( Jeong¸ Yun Young ),김태진 ( Kim¸ Tae Jin ) 한국기초조형학회 2021 기초조형학연구 Vol.22 No.1

본 논문은 추상 회화에서 존재와 시간이 맺는 관계가 상호적으로 수렴되며 화면에 형상화되는 과정에 관한 연구이다. 오늘날의 시각 예술은 서로 다른 시· 공간의 다원성, 이질성, 혼성성의 특징을 보이며, 개별화하고 있다. 이 같은 동시대의 맥락 안에서 연구자의 작업은 혼성적 요소 사이의 상호작용을 바탕으로 한 직관적 방향성의 생성, 그것이 일종의 불확실성을 전제한 조형 언어로서 작동한다는 점이 다. 연구의 목적은 실존에 관한 관심에 기반하여 가시적인 것에 제한되지 않고, 현존을 드러내는 해방 공간으로서의 추상 회화를 다시금 고찰하며, 연구자의 작업에 담긴 인간의 미묘한 감성과 숭고한 정서 의 충돌이 공존하고 교차하는 과정을 추적하고, 이를 바탕으로 경계를 희석하는 새로운 종합의 틀을 제시하여 동시대 미술의 창조적 시각을 견인하는 개념을 차별화하기 위함이다. 연구 방법에 있어서는 연구자의 작업에서 다룬 시간성과 실존성의 문제를 하이데거의 ‘세계-내-존재’ 개념으로 살펴봤고, 서사 공간으로서의 추상 회화에서 경계를 지우는 미와 추의 문제에 대해서는 로젠크란츠의 ‘추의 미 학’과 브룩스의 ‘육체와 예술’에 관한 입장을 참조했다. 추상적 화면에서 개입되는 우연성과 즉흥성에 있어서는 랑시에르의 ‘반 재현적 예술’을, 그 외 실존적 수용의 시각화 과정에 대해서는 로젠버그의 ‘개인의 정체성’, 라캉의 ‘주체성의 상실’, 베르그송의 ‘직관’ 개념 등 다양한 양식의 융합을 통해 하나 의 작품이 지니는 순수조형의 차원을 벗어나 경계의 확장을 꾀하였다. 결론적으로 연구자의 작업 속 ‘실존성’은 시간 속에서 관계적으로 공간을 교차하는 서로 다른 궤적의 결합 그 자체다. 형상의 해체와 전환이 반복되는 추상 회화는 ‘하나의 연속’이며, 영속적 미완의 상태로서 관계성에 대한 논의를 확장 시킨다. 의식의 복합적 차원을 다루며 실존성을 수용해가는 회화적 매체와 미학적 가능성을 탐구하는 것은 추상에 접근하는 또 다른 방법론으로서, 회화의 실천적 자율성을 재인식했다는데 의의가 있다. This research is the study on the process of relationship between existence and time in abstract painting that is mutually converged and shaped on the screen. Today's visual arts are characterized and individualized by the features of plurality, heterogeneity, and hybridity of different times and spaces. Within this contemporary context, the researcher's work is based on the generation of intuitive directions that are based on interactions between hybrid elements, which operate as a formative language preconditioned with the kind of uncertainty. The purpose of this re-examination of abstract paintings, as a liberating space that reveals the underlying existence, which is not only limited to visibility, is to trace the process of collisions of human subtle sensibilities and emotions. On that basis, by presenting a new framework of synthesis, the approach was made to dilute the boundaries of creative vision of contemporary art. As for the research methods, the matter of timeliness and existentiality was examined by borrowing concepts from Heidegger's In-der-Welt-sein, and the issue of beauty and ugliness that is absent of boundary was adopted from Rosenkranz's Aesthetics of Ugliness and Brooks’s Body Work. As for the coincidence and improvisation on the abstract screen, Ranciere's Anti-replicated Art and Rosenberg's Individual Identity, Lacan's Loss of Subjectivity and Bergson's Intuition were adopted in terms of the visualization process of existential acceptance. As for the result, the existence in the researcher's work is itself a combination of different trajectories that go across spaces in relation with time. Abstract paintings, which repeatedly dismantle and transition features, are one continuous flow and expand the concept of the interconnectedness as a permanent unfinished state. Addressing the complex dimensions of consciousness and exploring pictorial media and aesthetic possibilities that embrace existentiality is another methodology that approaches abstraction, which is meaningful in that it examines practical autonomy of painting in a new light.

To determine the characteristic double contrast barium enema findings of ileo-cecal and colonic tuberculosis and to make differential diagnosis from other bowel inflammatory disease. Sixty-seven patients confirmed as ileo-cecal and/or colonic-tuberculosis in six hospitals were evaluated retrospectively. The diagnosis was proven by endoscopic biopsy, surgery, and clinical follow up. Nine of 67 patients were excluded because radiologic findings were normal though endocopic biopsy examinations resulted in tuberculosis. Histopathological diagnosis were madein 58 cases as follows: endoscopic biopsy(n=29), operation(n=12), follow up examination(n=14), tissue culture(n=1), laparoscopic biopsy(n=2). There were 30 men and 28 females. The mean age were 36 yrs(range:16-67), 34 patients were in the second and third decade. The distribution of lesions, morphological characteristics, mucosal changes, ulcer shape and depth, associated with other tuberculous lesion, multiplicity were retrospectively analyzed in the findngs of double contrast barim enema. The commonest clinical symptoms were abdominal pain(n=35, 60%) and diarrhea(n=18, 31%). The chest radiography revealed association of pulmonary tuberculosis in 39 cases. Tuberculous lesions of other organs except chest were present in five cases. Double contrast barium enema findings showed a thickening and irregularity of intestinal mucosal fold(n=29, 50%), bowel contraction and/or shortening(n=26, 45%). There were small, nodular, superficial ulcers in the case of ulcer depth less than 2 mm in the depth. As many as 39 cases(67%) in this series had two or more lesions in the intestinal tuberculosis. The involved segment revealed symmetrical feature(n=21, 36%). Inflammatory pseudopolypoid lesions were noted in 30 cases(52%). The ileo-cecal region was involved in 38 cases(66%). The ascending colon(n=25, 43%) was the second commonest site with or without contiguous cecal involvement. Lesions in terminal ileum, ileo-cecal valve, transverse colon, descending colon and appendix were seen in 19, 18, 18, 12 and seven cases, respectively. Among 18 cases of ileo-cecal valve lesions, there were incompetency in nine cases(16%) and wide gapping in four cases(7%). In 14 cases, tuberculous enterocolitis was diagnosed by clinical follow-up and double contrast barium enema study. 12 out of 14 cases, the findings of double contrast barium enema of tuberculous enterocolitis were normalized after anti-tuberculous medication. However, two cases showed more aggravated state than before due to inappropriate treatment. Double contrast barium enema plays an important role in the diagnosis of tuberculous enterocolitis, determines the type, site and extent of the involvement and helps in treatment guide by using sequential studies.
