Cerebral amyloid angiopathy can cause intracerebral hemorrhage, progressive dementia, seizure and transient ischemic attacks. Dementia is a relatively common manifestation and associated with the presence of recurrent strokes and leukoencephalopathy. A 66-year-old right-handed man with hypertension and recurrent strokes presented with rapidly progressive dementia and sudden onset of dysarthria and dizziness. He showed memory impairment, personality and behavioral changes, and executive dysfunction for one and an half years. These symptoms developed insidiously and quite rapidly without fluctuation. Brain CT showed a small hemorrhage in the right cerebellum. Brain MRI, especially gradient-echo images revealed multiple cortical and cortico-subcortical microbleeds. Four weeks later, right hemiparesis suddenly developed and a repeated MRI showed a new left corona radiata infarction. We learn from this case that gradient-echo MR images should be performed in patients with rapidly progressive dementia and recurrent strokes.

자활후견기관사업 참여자가구의 제반 특성 및 경제적 어려움 정도에 영향을 미치는 요인에 관한 실증적 연구

유태균,김경휘 한국사회보장학회 2003 사회보장연구 Vol.19 No.1

시행 2년 6개월째로 접어들고 있는 자활지원사업에 대한 체계적이고 실증적인 연구의 부족은 자활사업 참여자(가구)의 특성을 이해하는데 필요한 자료의 부재라는 결과를 초래했다. 본 연구에서는, 이러한 자료 및 연구의 부재에 대한 인식을 바탕으로, 자활사업 참여자(가구)의 특성을 파악함과 동시에 이들의 경제적 어려움 정도에 영향을 미치는 요인을 실증적으로 규명 해보고자 시도하였다. 2002-2003년 말까지 2년간의 기간동안 계획된 4차례의 패널조사를 가운데 2002년 상반기에 완료된 1차년도 1차조사 자료를 분석한 결과, 첫째, 자활사업 참여자가구의 특성 가운데 경제활동을 하는 가구원의 유무, 사적이전소득 유무, 그리고 지역사회로부터의 지지정도가 자활사업에 참여하고 있는 참여자(가구)의 경제적 어려움의 정도에 결정적인 영향을 미치는 요인임을 발견할 수 있었고, 둘째, 자활지원사업에 참여하면서 가구의 총소득이 최저생계 유지를 위해 필요한 생계비에 미치는 못하는 '경제적 고위험집단(Financial High-Risk Group)'을 효과적으로 지원하기 위한 전략으로 자활사업 참여자에 대한 교육, 가족기능 증진을 위한 지원, 그리고 요보호 가구원을 가진 가구를 위한 지원이 시급하다는 사실을 알 수 있었다. Understanding the characteristics of the households participating the Self-Support programs(55P) launched in 2000 is of imperative in that little has been known up to date due to the lack of empirical study on 55P In realizing this lack of knowledge, these researchers have collected panel data on the households in SSP by conducting a total of four survey researches for the period of 2002-2003. Using the data collected from the 1st wave survey completed in May, 2002, these authors empirically examine the characteristics of this group as well as those factors affecting their financial suffering, Data analyses show 1) that whether or not having at least one working family member, the availability of the source of private income transfer, and the level of support from the community are the major determinants of the level of the household's financial suffering in 5SP, 2) that effective supporting strategies for those households that can be categorized into 'Financial High-Risk Croup', whose total household income falls short of the amount of expenditure for basic living even in SSP should include educating the 5SP participants, strengthening the level of family functioning, and providing the SSP participants with child-care services and social services for the elderly and people with chronic mental and physical problems, and 3) that for the government it is necessary to suspect in a serious manner the reasonableness of setting the goal of SSP as transforming SSPs into the Self-Sufficient Community. Some policy suggestions are made for the development of the Self-Support programs in the future.

Ventricular myocytes of guinea-pig were isolated by means of collagenase digestion in order to investigate the effects of papaverine on the membrane currents in them. After formation of a gigaseal with patch microelectrodes, membrane currents were recorded from single ventricular myocytes in a whole cell mode of patch-clamp technique. For membrane currents recording, electrodes were filled with Cs-solution. Results were as follows: 1. Slow inward calcium was reduced by papaverine dose-dependently. 2. No significant changes were observed in the steady-state inactivation. 3. Recovery time of the calcium currents prolonged in high concencial papaverine. 4. Fast inward sodium currents showed no noticeable changes with papaverine treatment. From these results, it is strongly suggested that the effects of papaverine on the membrane currents in the single ventricular myocytes may be attributable to its antagonistic action on the calcium channel rather than its inhibitory effect on the phosphodiesterase activity.

Gastrointestinal tumors(GIST) are rare group of neoplasias of the gastrointestinal track, which originate from or differentiate into interstitial cells of Cajal (ICC). GIST traditionally have been designated as smooth muscle tumor. However, with increasingly accurate analytic tools, immunohistochemistry and ultrastructure, most investigators were able to demonstrate that ICC, a complex cellular network postulated to act as pacemaker cells of the gastrointestinal track, which exhibit both myoid and neural features, could be a candidate for tumor histogenesis. Most ICC are only c-kit-positive, however a subset are positive for both c-kit and CD34. Most GISTs are asymptomatic and are thus usually discovered incidentally during routine check, at operation of other organs. When symptoms occur, GISTs usually present with gastrointestinal bleeding due to ulceration of the overlying gastric mucosa. Bleeding may be massive, leading to hematemesis and melena. Recently, we experienced a large sized(5×5×5 cm) GIST on the upper body of the stomach, which caused massive upper gastrointestinal bleeding in a 61-year-old man and was treated by local resection with adequate safety margin about 2 cm.

Fineness Modulus is a term used as an index to the fineness of sand. It is well - known that the modulus distribution of sand plays an important role in achieving the desired properties of mortar. The maximum size of sand is also important parameter in mortar. These parameters affect workability, strength and unitweight of mortar. In tills study, different sand gradings were used to investigate effects of fineness moduli of sand for examination about the workability, strength and unit weight characteristics of cement mortar. Two kinds of sands with various size distribution and three kinds of fine aggregates with the similar particle size distribution (Sieve No.16~30, No.30~50, No.50~100) were used. Water-cement ratio (W/C) of mortar mix was kept constant for all the trial mixes with sand of different fineness modulus. Major findings of tills study are: (a) Fine sand with the similar size distribution reduces the workability and unit weight of cement mortar. (b) The compressive strength of mortar is not sensitive to sand grading variations. (c) The compressive strengths at the age of 28 days range from 32.1 to 54.1 MPa. (d) The sand with standard modulus distribution has better positive effects on the properties of the mortar.

Purpose : To evaluate the reliability and clinical usefulness of ultrasonography in the temporomandibular joint (TMJ). Materials and Methods : Parasagittal and paracoronal 1.5 T MR images and 7.5MHz ultrasonographs of 40 TMJs in 20 asymptomatic volunteers were obtained. Disc position using MR imaging was evaluated and the distance between the lateral surface of mandibular condyle and the articular capsule using MR image and ultrasonograph of 27 TMJs with normal disc position was measured and compared. Intraobserver and interobserver measurements reliability was evaluated by using interclass correlation coefficients(ICC) and measurement error. Also, the distance measured on ultrasonographs was compared, according to mouth position and disc postion. Results : The normal disc position was found in 27 of 40 asymptomatic joints. At the intraobserver reliability of measurement, ICC at the closed and open mouth position were 0.89 and 0.91. The measurement error was 0.4% and 0.5%. At the interobserver reliability, ICC at the closed and open mouth position were 0.92 and 0.81. The measurement error was 0.4% and 0.7%. At the TMJ with normal disc position, the distances between the lateral surface of mandibular condyle and the articular capsule measured on MR images and ultrasonographs were 2.0±0.7 mm, 1.8±0.5 mm, respectively(p<0.05). On the ultrasonographs, the distances at open mouth position were 1.2±0.5 mm (p<0.05). At the TMJ with medially displaced disc, the distances at the closed and open mouth position were 1.3±0.3 mm and 0.9±0.2 mm (p<0.05). Conclusion: The results suggest ultrasonography of TMJ is a reliable imaging technique for assessment of normal disc position. (Korean J Oral Maxillofac Radiol 2006; 36 : 41-8)
