        대상포진 환자의 임상적 관찰 ( 1990 - 1994 )

        김시영,조보현,김중환 ( Si Young Kim,Bo Hyun Cho,Joong Hwan Kim ) 대한피부과학회 1997 大韓皮膚科學會誌 Vol.35 No.2

        Background: Herpes zoster is an important and troublesome disease. Objective. The purpose of this study was the elucidation of the epidemiological and clinical characteristics of herpes zoster through patient assessrnent. Methods. During a 5- Year period, January 1990 to December 1994, 215 patients with herpes zoster were assessed with regard to annual and monthly frequency in occurrence, age and gender incidence. Associated conditions, dermatomic distributions, the relationship of onset of pain and skin lesions, Multi-CMI test and complications were also evaluated. Results : 1. The annual freguency of herpes zoster ranged from 0.88% to 1.78% (mean 1.23%) during the 5-year period. The highest number of herpes zoster patients was observed in winter (p<0. 001) especially in January. 2. Herpes zoster was found to most frequently afflict persons aged 50-59(27.9%). 71% of the patients were over 40 years of age. 3. In 76 patients(41.8%), neuralgia occurred several days(4 days mean) before the development of skin lesions. In 92 patients(50.5%), pain and skin lesions developed simultaneously while skin lesion development occurred before the onset of pain in 14 patients(7.7%). 4. Among the patients, 42.8% had associated conditions such as diabetes mellitus, hypertension, pulmonary tuberculosis, liver diseases, peptic ulcer, hypothyroidism, pharyngitis, fracture, etc. 5. The dermatomic invclvement of herpes zoster patients having one dermatome was most frequent in thoracic dermatome ca. es(52.6%). Others included cervical(16.7%), trigeminal(11.6%), sacral(6. 0%), lumbar(4.2%), facial(0.5%). Cases having two different dermatomes constituted 8.4%. 6. The most common complication of herpes zoster was postherpetic neuralgia although instance of ophthalmologic compiications, secondary bacterial infection, scar formation, Ramsay-Hunt syndrome, keloid formation, and urinary difficulty were also documented. 7. Multi-CMI(Cell-mediated immunity) tests were done on 88 herpes zoster patients. Thirteen of them(14.8%) were found to have comparatively depressed scores. Ten of the 79 single dermatome involvement patients(12.7%) and three of the 9 two dermatome involvement patients(33.3%) exhibited similar scores. Conclusion : These results are in accordance with those of previous reports with the exception of the higher incidence ot two different dermatome involvements and seasonal variation.

        폐쇄성 수면무호흡 증후군에서 앙와위 자세시간과 수면관련변인 간 상관관계 분석

        김시영,박두흠,유재학,유승호,하지현,Kim, Si Young,Park, Doo-Heum,Yu, Jaehak,Ryu, Seung-Ho,Ha, Ji-Hyeon 대한수면의학회 2017 수면·정신생리 Vol.24 No.1

        목 적 : 폐쇄성 수면무호흡 증후군(obstructive sleep apnea syndrome, OSAS)에서 앙와위는 비앙와위보다 수면무호흡을 증가시키는 것으로 알려져 있다. 앙와위 자세시간(supine position time, SPT)과 OSAS의 무호흡-저호흡 지수(apnea-hypopnea index, AHI)의 관련성에 대해서 많은 연구가 있었으나, SPT가 OSAS에서 어떤 변수의 영향을 받는지는 알려져 있지 않다. OSAS에서 수면다원검사상 어떤 변수가 SPT과 관련이 있는지를 평가하였다. 방 법 : 수면다원검사로 진단된 치료받지 않은 365 명의 OSAS 남자 환자를 선정하였다. SPT($276.4{\pm}92.3$ 분)가 인구 통계학적 데이터, 수면구조 관련변수, OSAS 관련변수 및 심박변이도(Heart rate variability, HRV)와 상관관계가 있는지 분석했다. SPT에 영향을 주는 요인을 알아보기 위해 SPT에 대해 다중회귀분석을 시행하였다. 결 과 : 전체 대상군의 상관분석에서 SPT는 총수면시간(total sleep time, TST) (r = 0.443, p < 0.001)과 수면 효율(r = 0.300, p < 0.001)과 가장 유의한 상관관계가 있었고, 코골이 시간(r = 0.238, p < 0.001), 산소포화도 90 % 미만시간(r = 0.188, p < 0.001), AHI (r = 0.180, p = 0.001), 산소탈포화지수(oxygen desaturation index, ODI), (r = 0.149, p = 0.004), NN50 count(r = 0.137, p = 0.036)와 SPT 간에 유의한 상관관계가 있었다. 다중회귀분석 결과 SPT에 유의한 영향을 끼치는 요인으로 TST (t = 7.781, p < 0.001), 코골이 시간(t = 3.794, p < 0.001), AHI (t = 3.768, p < 0.001), NN50 count (t = 1.993, p = 0.047)가 있었다. 결 론 : SPT는 OSAS 관련변수보다 수면구조 관련변수와 더 높은 상관관계를 보였다. 특히 SPT는 TST과 AHI 뿐만 아니라 NN50 count와도 밀접하게 관련되어 있었다. 이것은 SPT가 OSAS의 심각도뿐만 아니라 수면구조와 심박변이도에 의해서도 결정될 가능성이 있음을 시사한다. Objectives: A supine sleep position increases sleep apneas compared to non-supine positions in obstructive sleep apnea syndrome (OSAS). However, supine position time (SPT) is not highly associated with apnea-hypopnea index (AHI) in OSAS. We evaluated the correlation among sleep-related variables and SPT in OSAS. Methods: A total of 365 men with OSAS were enrolled in this study. We analyzed how SPT was correlated with demographic data, sleep structure-related variables, OSAS-related variables and heart rate variability (HRV). Multiple linear regression analysis was conducted to investigate the factors that affected SPT. Results: SPT had the most significant correlation with total sleep time (TST ; r = 0.443, p < 0.001), followed by sleep efficiency (SE ; r = 0.300, p < 0.001). Snoring time (r = 0.238, p < 0.001), time at < 90% SpO2 (r = 0.188, p < 0.001), apnea-hypopnea index (AHI ; r = 0.180, p = 0.001) and oxygen desaturation index (ODI ; r = 0.149, p = 0.004) were significantly correlated with SPT. Multiple regression analysis revealed that TST (t = 7.781, p < 0.001), snoring time (t = 3.794, p < 0.001), AHI (t = 3.768, p < 0.001) and NN50 count (t = 1.993, p = 0.047) were associated with SPT. Conclusion: SPT was more highly associated with sleep structure-related parameters than OSAS-related variables. SPT was correlated with TST, SE, AHI, snoring time and NN50 count. This suggests that SPT is likely to be determined by sleep structure, HRV and the severity of OSAS.

        김시영(Si Young Kim),박순호(Soon Ho Park) 한국언어치료학회 2018 言語治療硏究 Vol.27 No.3

        목적: 본 연구는 언어장애와 재활서비스에 대한 유아교사의 인식 및 교사연수현황을 파악하여, 유아교사의 언어장애 인식향상을 위한 기초자료를 제공하는데 목적이 있다. 방법: 본 연구는 어린이집 및 유치원 교사를 대상으로 하였다. 설문지는 총 250부를 배부하였고, 수거된 설문지 중 불성실한 답변을 제외한 183부를 최종 분석대상으로 하였다. 설문지 구성은 일반정보 8문항, 교육현장현황 7문항, 교사교육현황 2문항, 언어장애 인식 13문항, 재활서비스 인식 12문항으로 이루어졌다. 이중 언어장애 인식의 8문항과 재활서비스 인식의 7문항은 5점 척도로 구성되었다. 통계처리는 SPSS 20.0 프로그램을 이용하여 t-검정, 교차분석을 실시하였다. 결과: 첫째, 유아교육 현장에서는 학급에 언어장애아가 없다는 경우(69.9%)가 있다는 경우(20.2%)보다 높았으며, 언어장애가 있을 경우 한 학급당 1-2명(44.3%)이라는 대답이 많았다. 둘째, 언어장애에 대한 연수경험은 없다는 경우가 77.6%였다. 재활서비스에 대한 연수경험은 86.9%가 없다고 하였다. 셋째, 유아교사들이 알고 있는 장애는 자폐스펙트럼장애(18.2%), 청각장애(17.2%), 지적장애(16.8%) 순으로 나타났다. 넷째, 유아교사의 재활서비스에 대한 인식에서 아동에게 언어문제가 있을 경우 학부모에게 권유하겠다는 의사가 89.1%로 나타났다. 결론: 교사의 전문지식에 대한 교육뿐만 아니라, 부모교육을 통해 조기중재를 통한 효과를 강조하고 조기치료가 중요하다는 부모의 인식개선이 필요하다. 근무기관간의 비교에서 유치원교사 및 어린이집 교사 모두 언어장애에 대한 인식정도가 보통 이하였으므로 교사양성과정 및 현직교육에서의 인식향상 교육이 필요함을 의미한다. 또한 현직교사교육에서도 경력과 직급, 교육기관을 나누어 실시할 필요가 있다. 연구의 결과로 유아교사가 유아에게는 효율적인 교육적 지원을 실시하고, 부모에게는 재활치료서비스 정보를 제공할 수 있게 되기를 고대한다. Purpose: In this study, early childhood teachers recognition of speech-language disorders and rehabilitation services was identified. The purpose of this study is providing basic data for early childhood teachers to improve the recognition of speech-language disorders. Methods: Total 250 questionnaires were distributed and total 183 questionnaires were subject of analysis. Statistical treatment performed t-test, crossed dispersion by using SPSS 20.0 program. Results: First, in children education sites, there were more children without speech-language disorder in the class(69.9%). If there are children with speech-language disorders, there are 1-2 students per class(44.3%). Second, 77,6% of subjects didn’t have workshop experience of speech-language disorder in the class. 86.9% of subjects didn’t have workshop experience of rehabilitation service. Third, early childhood teachers knew autism spectrum(18.2%), auditory disorder(17.2%), intellectual disability(16.8%) in order. Fourth, in recognition of rehabilitation service of early childhood teachers, if there is speech-language problem to children, 89.1% teachers recommend rehabilitation service. Conclusions: Education of teachers’ professional knowledge is needed that early curing is important through parents’ education by highlighting efficiency of early intervention. Recognition improvement education is needed because kindergarten and daycare center teachers’ recognition is under the average in comparison of forms between working sites. Education for teachers needs to be divided in detail: the newly appointed, the experienced, common teachers, teachers specialized for the disabled, director, etc. Through result of study, we are looking forward that early childhood teachers can offer educational help efficiently to children and rehabilitation curing service information to parents.

        팽창밸브 개폐용 감온통 혼합가스의 첨가제 연구

        김시영(Si-Young Kim),주창식(Chang-Sik Ju),구수진(Su-Jin Koo) 한국동력기계공학회 2014 한국동력기계공학회지 Vol.18 No.6

        The P-T characteristics of mixed refrigerant in thermostatic expansion valve sensing bulb were studied using R-134a and R-410A refrigerant. The characteristics of mixed refrigerant were investigated according to pressure variation and the variation of composition ratio of R-134A and R-410A in the temperature range of ?15℃∼15℃. The Thermodynamic characteristic values of the mixed refrigerants were identified using the characteristic value analysis program of mixed refrigerant(Refrop v9.0, NIST). The P-T characteristics in the case of the mixing ratio of 90:10 for R-410A and R-134A were the same result as R-22. And the physical properties showed similar results with R-22. The Maximum operating pressure(MOP) of mixed refrigerant showed a tendency to decrease with decreasing the mixing ratio of additive gases(N<SUB>2</SUB> or He) gases. The characteristics in the case of the mixing ratio of 80:1 for mixed refrigerant and additive gases were the similar result as Reference refrigerant.(R-22 MOP, Sporlan company) In addition N<SUB>2</SUB> and He, both showed the same results. It was able to confirm that a MOP on the thermostatic expansion valve sensing bulb can be maintained by adjusting the mixing ratio of mixed refrigerant gases and additive gases.
