Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

연구목적: 이성대상포진에 동반되는 안면신경마비는 Bell's palsy와는 달리 예후가 더 나쁘고 그 마비가 완전히 회복되지 않는 경우가 더 많다.본 연구에서는 이성대상포진에서 발현되는 증상들의 유무가 치료 전 안면신경마비의 정도 및 치료 후 예후와 상관관계가 있는지를 관찰하여 예후의 예측인자에 대해 분석하였다. 재료 및 방법: 지난 1992년 1월부터 1999년 6월까지 이성대상포진으로 진단받고 본원에 입원하여 고용량 부신피질호르몬제와 항바이러스제인 acyclovir의 병합투여로 동일한 치료를 받은 30명의 환자를 대상으로 후향적으로 의무기록을 분석 및 고찰하였으며, 치료 전 안면마비의 정도와 치료 후 마비의 회복 정도를 이통, 이명, 난청, 현훈 등의 증상의 유무와 치료 시작 시기, 그리고 안면신경의 electroneuronography(ENoG) 값에 따라 비교하였다. 결과: 이성대상포진수포가 안면신경마비 보다 먼저 발현된 경우에 안면신경마비의 치료 전 grade가 통계적으로 유의하게 좋았다(p<0.05).이통, 청력손실, 그리고 현훈의 유무에 따른 안면신경마비의 정도는 상관관계가 없었고 예후에도 차이가 없었다.이명의 유무에 따른 치료 전 안면신경마비의 정도는 상관관계가 없었으나 치료 후 완전회복율은 이명이 있었던 군에서 통계적으로 유의하게 높았다(p=0.003<0.05).완전회복군과 불완전회복군 사이의 치료 전 ENoG의 수치는 통계적으로 유의하게 예후와 상관이 있었다(p=0.037<0.05). 결론: 좀더 많은 수의 환자를 연구에 포함하여 증상에 따른 예후의 차이를 연구하는 것이 필 요하며 또한 ENoG 값이 10%에서 40% 사이인 환자들의 치료 방법에 대한 고려와 이성대상포진수포가 안면신경마비보다 먼저 생긴 환자에서 치료 전 마비정도가 경미했던 이유에 대한 연구가 필요할 것으로 생각된다. Purpose: Herpes zoster oticus generally has a poor prognosis, leaving many patients with permanent facial nerve dysfunction, compare to Bell's palsy.Acyclovir and prednisolone have been widely used for the treatment of herpes zoster oticus.This retrospective study was conducted to suggest the prognostic factors according to various symptoms. Materials and Methods : Clinical studies were retrospectively performed on 30 patients with herpes zoster oticus who were treated with acyclovir and prednisolone in the Chungbuk National University Hospital between 1991 and 1999.The authors analyze the pre-treatment grade and prognosis of facial nerve palsy according to symptoms(the existence of otalgia, tinnitus, hearing loss, and vertigo), the treatment onset, and electroneuronography ( ENoG ). Results : Of thirty patients who have been diagnosed as herpes zoster oticus, there is no significant difference in the pre-treatment grade of facial nerve palsy according to the existence of vesicle, otalgia, tinnitus, vertigo, and hearing loss.Of 25 patients who have facial nerve palsy, the recovery from the palsy is complete in 14 patients(56%).There is no significant difference in the pre-treatment grade of facial nerve palsy according to the existence of otalgia, tinnitus, vertigo, and hearing loss.The pre-treatment grade of facial palsy is better when the vesicles precede facial in the group with tinnitus than without tinnitus.A significant difference of the prognosis according to the onset of treatment and other symptoms are not found.ENoG is better in the group that facial nerve palsy is completely recovered than incomplete recovery group. Conclusion : Reliable prognostic factor according to symptoms is not found, ENoG is the only prognostic factor.

신정옥 韓南大學校 敎育硏究所 2011 교육연구 Vol.19 No.2

본 연구는 대학생이 지각하는 사회적 지지가 진로장애와 진로결정자기효능감을 매개로 진로결정수준에 어떤 영향을 미치는지 검증하는데 목적이 있다. 연구대상은 4년제와 2년제에 재학중인 대학생 642명으로, 사회적 지지 척도, 진로장애 척도, 진로결정자기효능감 척도, 진로결정수준 척도를 사용하였다. 사회적 지지와 진로결정수준 간의 관계에서 진로장애와 진로결정자기효능감이 매개변수로 작용할 것이라는 연구모형을 도출하였고, 구조방정식을 통해 이를 확인하였다. 연구결과는 다음과 같다. 첫째, 대학생이 지각하는 사회적 지지는 진로장애에 부적인 직접효과가 있었다. 둘째, 사회적 지지는 진로결정자기효능감에 대해 직접효과와 더불어 진로장애를 통한 매개효과를 가지고 있었다. 셋째, 사회적 지지는 진로장애와 진로결정자기효능감을 매개로 진로결정수준에 영향을 미치는 것으로 나타났다. 대학생의 진로결정수준을 향상시키기 위해서는 사회·환경적 맥락 차원과 개인 내적 변인을 함께 고려한 통합적인 접근이 이루어질 필요가 있으며, 진로결정자기효능감에 따른 진로장애와 사회적 지지에 대한 연구가 후속적으로 수행될 필요가 있다. The present study examined the mediating social supports, and career decision making self efficacy, base on the relationship between career barriers and career decision. 642 four years college students or two years students completed a self report questionnaire that measured the social supports, career barriers, career decision making self efficacy, and career decision. Results showed the more adolescents felt social supports the easier it was for them to recover career barriers. Social supports mediating hypothesis is supported as a function of career decision making self efficacy and career barriers. Similarly, career decision making self efficacy, and career barriers mediated as a function of social supports and career decision. We will study that career decision making self efficacy depend on social supports and career barriers perception.

The waxy rice flours were prepared from Sinsunchalbyeo and Hwasunchalbyeo using dry-pin and wet-roller mill, and the properties were investigated. Proximate composition and physicochemical properties of waxy rice flours were similar between two varities, but were different between milling methods. Water binding capacities, soluble carbohydrates and damage starch contents of waxy rice flours were similar between two varities, but were higher in waxy rice flour using wet-roller milling method than using dry-pin milling method. The crystallinities by X-ray diffractorgrams were all A-type. By Scanning Electron Microscope, waxy rice flours were shown large granule surrounded with film like material and the granules were attached with starch granules. The film like material was more tightly bound with granules in flours by dry-pin milling method. Peak viscosity of wet-roller milled flours by Rapid Visco Analyzer(RVA) was higher than that of dry-pin milled ones, but initial gelatinization temperatures were lower in flours by wet-roller milling method.

Objective : Our purpose of this study was to evaluated the incidence of twin pregnancy with one fetal demise, predisposing factors and the maternal complications and perinatal outcomes. Patients : From January 1993 to December 1997, 5 twin pregnancy with single fetal demise after 28 weeks gestation by gestational age were observed in Soonchunhyang Kumi Hospital. Results : 1. The incidence of one fetal demise was 3.01% in twin pregnancy. 2. Maternal disseminated intravascular coagulation has not been demonstrated. 3. The predisposing factors of twin pregnancy with single fetal demise are umbilical cord torsion (40%), congenital anomaly(20%) and unknown(40%). 4. According to chorionicity, it seems that the perinatal mortality rate of monochorionic group was higher than dichorionic. Conclusion : This study suggests that monochorionic placentation is associated with increased risks of twin pregnancy with single fetal demise. But it may be partially explained due to small numbers of cases in this study.

김정옥,신말식 한국조리과학회 2003 한국식품조리과학회지 Vol.19 No.1

멥쌀전분, 찹쌀가루, 멥쌀전분으로 제조한 RS3형 저항전분의 수분 함량은 비슷하였으나, 단백질 함량, 회분 함량, 지방질 함량은 찹쌀가루가 가장 높았다. 멥쌀전분으로 제조한 RS3형 저항전분의 RS함량은 9.10% 이었다. 멥쌀전분으로 제조한 RS3형 저항전분을 첨가한 인절미 경도와 부착성을 레오메타로 측정하였을 때 저장기간과 RS3형 저항전분의 첨가량이 증가할수록 증가하였다. 관능검사 결과, RS3형 저항전분을 첨가한 인절미의 경도가 무첨가 인절미보다 높은 값을 보였으나, 탄성, 부착성, 부드러움성, 전체적인 품질은 RS3형 저항전분의 첨가량에 따라 유의적인 차이를 보이지 않았으며, 전체적인 품질은 경도와 음의 상관관계를 보였다(r=-0.331, p<0.05). The objective of this study was to compare the textural properties and sensory evaluation of injulmi, a traditional Korean waxy rice cake, added with 10, 20 and 30% of RS3-type resistant starch. RS3-type resistant starch was prepared from nonwaxy rice(Odaebyeo) starch by autoclaving-cycle. The RS yield of RS3-type resistant starch was 9.10%. By increasing the addition level of RS3 -type resistant starch, the hardness and adhesiveness of Injulmi increased as measured by using a rheometer. Hunter color L and a values of Inulmi added with RS3-type resistant starch were increased, but b value was decreased. In case of sensory evaluation, the hardness of Injulmi added with RS3-type resistant starch was higher than that of non-added Injulmi. The overall quality of Injulmi added with RS3-type resistant starch by sensory evaluation was negatively correlated with the hardness neasured by rheometer
