Common peroneal nerve palsy is one of the most frequently encountered nerve injuries. The reason for this is the superficial portion of the nerve as it curves around the head of the fibula where it is subject to direct trauma, pressure, or other injuries. In acute stage, when clinical paralysis appears to be complete, electrophysiologic studies are useful guides to predict prognosis. In many of incomplete clinical recovery, the degree of recovery is dependent on rather EMG findings and motor nerve conduction velocities than clinical findings. A retrospective analysis of clinical and electrodiagnostic findings of the 19 cases of common peroneal nerve palsy with follow up seen from January 1987 to August 1989 in the Department of Rehabilitation Medicine at Chungnam National University Hospital was carried out. The results of these studies were as follows. 1. Among the common peroneal nerve injuries, ones accompained by trauma, especially fracture showed relatively poor clinical recovery and ones with compression or spontaneous onset showed better recovery. 2. The clinical recovery was relatively poor when the conduction velocity distal to the fibular head was delayed or when the compound muscle action potential was not obtained over extensor digitorum brevis in the initial motor conduction studies. 3. The clinical recovery was relatively better when the initial sensory conduction studies showed normal sensory distal latency, while the recovery was worse when the sensory nrve action potential was absent or the amplitude was smaller than 50% of that of the non-paralyzed contralateral side.

Vinblastine이 백서 배양 Type-1 별아교세포에 미치는 세포독성에 관한 연구

하상호,박승택,문연자,김종영,김정중,정연태 圓光大學校 醫科學硏究所 1994 圓光醫科學 Vol.10 No.1-2

It has been reported that vinblastine, anticancer drug, is a neuroteratogen inducing various neural malformations such as microcephaly and neural tube defect(NTD), but the study on the toxicity of neuroglial cells, especially type-1 astrocytes using culture system is not well established. In order to evaluate the cytotoxicity of vinblastine on cultured type-1 astrocytes of neonatal rat brain in vitro. MTT assay and also light and electron microscopic studies were carried out. The results were as follows: 1. MTT_90 and MTT_50 in cultured type-1 astrocytes were 1×10 exp (-1) μM and 1×10 exp (2)μM of vinblastine, respectively. 2. Vinblastine was highly toxic in cultured type-1 astrocytes(MTT_50 ≤ 100 μM). 3. In a light microscopy, cultured type-1 astrocytes showed decrease of cells in number, cytoplasmic perforation, vacuolization and cytoplasmic granulation after cultured type-1 astrocytes were treated with 1×10 exp (2)μM of vinblastine for 24 hours. Cultured type-1 astrocytes damaged by vinblastine showed degenerative changes of cells morphologically. 4. In an electron microscopy, increment of glial fibrillary acidic protein(GFAP), increased free-ribosomes, cisternal dilatation of rough endoplasmic reticulum (rER). few dense bodies and vacuoles were shown in cultured type-1 astrocytes treated with 1×10 exp (2)μM of vinblastine for 24 hours. The results indicate that vinblastine has markedly cytotoxic effect on the type-1 astrocytes of neonatal rat brain in vitro study.

Rural Tourism 수요촉진에 관한 연구 : 해외사례 비교 A Case Study of Foreign Countries

노용호,김연선 한국문화관광학회 2004 문화관광연구 Vol.6 No.1

Rural tourism, which makes use of the farming community and agriculture, aims to contribute to creating off-farm income and economic profits. From this viewpoint, to begin with, as in examples of Britain, Germany, France, and Japan, the government should make proper policies; besides, various associations and organizations in agricultural industry should take the initiative to improve agricultural infrastructure. Secondly, along with the government's policies, farmers should devise ways to advertise their private accommodations and gain customers' confidence. Besides, They have to develop local tourist products through thorough understanding of their local areas, and by networking themselves, they need to give various information to consumers or city residents. As life in the city is getting more complicated and hard, rural tourism will establish itself as a future form of tourism as an alternative to experience nostalgia for the past and regain the tender feeling we are unconsciously losing. Consequently, we will have to strive to revive the worsening rural economy through rural tourism, and urban residents can also be able to use it as a means to find entertainment.

Objectives : This study was performed to investigate the clinical manifestations and labora-tory findings, and to see whether the severity of atopic dermatitis(AD) implies a relationship to the clinical and laboratory findings. Methods : Our study was designed by analyzing outpatients with AD via physical examinat-ion, questionnaires and laboratory investigations such as prick test to house dust mites, bacterial cultures, total IgE, IgA, IgG, IgG_4, IgM, and peripheral eosinophil count. Results : 1) Xerosis, ear fissuring and hyperlinear palms were related to the severity of AD(p<0.05). 2) Sweating, foods and aeroallrgen were related to the severity of AD(p<0.05). 3) The presence of family history of AD differed significantly(p<0.05) between the severe group(57.9%) & the mild group(26.3%). 4) The positivity of the prick test to Dermatophagoides pteronyssinus and D.farinae was found in 90.0% of respiratory group and in 30.0% of AD only(p<0.05%). 5) Serum IgE level was higher in the severe group(938.3±601.8 IU/mL) than the mild group(526.7±352.1IU/mL)(p<0.05). 6) Serum IgE level in AD patients with respiratory disease(1025.8±713.2IU/mL) was higher than AD only(403.3±273.4IU/mL)(p<0.05). 7) Peripheral eosinophil counts were higher in the severe group(509.9±389.4/㎣) than the mild group(340.5±219.4/㎣)(p<0.05). Conclusion : The factors related to severity of AD were xerosis, ear fissuring, hyperlinear palms, sweating, food, aeroallergen, serum IgE and peripheral eosinophil count. The AD pati-ents with respiratory allergic disease had higher IgE levels and higher positive rates of prick test with house dust mite.

연구대상 시설재배지 토양의 물리성은 대부분이 모래의 비율이 높은 sandy loam이나 loam으로 투수성이 양호할 것으로 판단되나, P2나 S1에서는 미사의 비율이 높은 미사 loam으로 투수성 및 통기성이 상대적으로 낮은 것으로 판단된다. 토양의 화학성은 EC의 경우 표토의 대부분이 기준치에 도달하거나, 초과하는 경향이었고, 심토의 경우는 기준치 이하로 조사되었다. 또한 유기물 함량은 적정수준 2~3%보다 조사 대상 지점의 대부분에서 상회하였고, 심토의 일부분도 이 수준을 넘는 곳도 있었다. 조사 대상 지역의 수질 특성 중 시설재배지 지하수의 가장 중요한 염류 지표인 EC는 연평균 0.48 dS/m로 농업용수로서 작물에 미치는 영향은 없는 것으로 판단되나, 수질오염지표인 질산성 질소의 경우 19.1 mg/L 로 농업용수 수질 기준인 20 mg/L에 근접한 수준을 나타내었다. 특히 조사 대상 지점의 36.4%가 수질 기준을 초과하는 것으로 나타났다. 지하수중의 이온의 양과 영양염류의 양을 간접적으로 나타내는 전기전도도인 EC는 양이온인 경우 Mg^(2+), Ca^(2+), Na^+, K^+와 정의상관이 있었으며, 특히 2가 양이온인 Mg^(2+)와 Ca^(2+)간에는 고도의 정의상관을 보이고 있었다. 또한 EC와 음이온간에는 NO_3^-, Cl^-, SO_4^(2-), PO_4^(2-)와 상관을 보이고 있었다. 지하수의 오염지표인 NO_3-N의 경우에는 COD를 제외한 모든 이온들과 상관을 보이고 있었다. 특히 SO_4^(2-), Cl^-, Na^+, Ca^(2+), Mg^(2+)와는 고도의 정의 상관을 보여주고 있다. 이는 NO_3-N는 EC와 함께 지하수오염의 중요한 지표중의 하나임을 보여주고 있다. The objective of this study was to know the qualities of soil and shallow groundwater in plastic film house fields around Central Part of Korea. The study was conducted at 11 sites in Suweon, Hwasung, Pyungtaek, Yongin, and Chuncheon through May to August in 1999. Soil textures of plastic films house were mainly sandy loam or loam. Electric conductivity and organic matter content of surface soils mostly exceeded the critical levels for crop production. Average concentration of N0_3-N in the shallow groundwater was 19.1 mg/L, and it reached almost the limiting level of agricultural groundwater quality (20 mg/L). Moreover about 36% of survey sites exceeded the limiting level of agricultural groundwater quality. Sulfate concentrations also at some sites exceeded agricultural groundwater quality limit level (50 mg/L). Nitrate-N, one of the most important factors in the groundwater quality, had positive correlations with other ions in groundwater.
