PURPOSE: The purpose of this study was to identify the effects of backward pedaling ergometer training on ankle ROM, lower extremities strength, foot pressure in hemiplegia. METHODS: The subjects consisted of control group(n=10) and experimental group(n=10), subjects were trained 5 times a week for 2 weeks each group. Control group were trained forward, experimental group were trained backward pedaling with physical therapy in both groups. Each group measured ankle joint ROM with DUALER IQ and ankle and knee joint flexor and extensor muscle strength by Manual Muscle Test System and foot pressure by Gait view system. RESULTS: The result of this study between pre and post test that experimental group had statistically significantly differences in ankle joint range of motion and lower extremities strength. But foot pressure had not statistically significant differences. There was not significantly difference of variation between groups. CONCLUSION: Therefore these results mean that backward and forward pedaling ergometer training effected an improvement of lower extremities function in hemiplegia.

하미선,도미향 한국코칭학회 2015 코칭연구 Vol.8 No.3

본 연구의 목적은 어린이집원장의 코칭리더십이 보육교사의 조직몰입과 이직의도에 미치는 영향을 알아보고자 하였다. 이를 위해 충청남도 소재의 어린이집에 근무하는 보육교사 287명 의 설문지를 빈도분석 및 백분율 산출, 평균과 표준편차 산출, 일원분산분석(ANOVA)과 T-test, Pearson의 적률상관계수 분석 및 단순선형회귀분석을 실시하였다. 결과로는 보육교사 가 지각한 원장의 코칭리더십과 조직몰입은 보통 이상이었으며 보육교사의 이직의도는 보통 이하로 인식하고 있었다. 보육교사가 지각한 원장의 코칭리더십과 보육교사의 조직몰입 및 이 직의도 간의 상관관계를 살펴본 결과 원장의 코칭리더십과 보육교사의 조직몰입은 전체적으 로 정적인 상관관계를 가지는 것으로 나타났으며, 원장의 코칭리더십과 이직의도 간에는 부정 적인 상관관계가 나타났다. 보육교사가 지각한 원장의 코칭리더십이 보육교사의 조직몰입에 미치는 영향으로는 원장의 코칭리더십이 높아질수록 보육교사의 조직몰입도 높아지는 것으로 나타났다. 보육교사가 지각한 원장의 코칭리더십이 보육교사의 이직의도에 미치는 영향으로 는 원장의 코칭리더십이 높아질수록 보육교사의 이직의도는 낮아지는 것으로 나타났다. The purpose of this study was to examine the influence of the coaching leadership of child care center principals on the organizational commitment and turnover intention of child care teachers. After conducting the surveys, the answer sheets from 287 child care teachers who worked in child care centers located in South Chungcheong Province were analyzed. For data analysis, the statistical package SPSS WIN 18.0 was utilized to conduct a frequency analysis. Additionally, statistical data on percentage, mean and standard deviation were obtained, and ANOVA, t-test, Pearson product-moment correlation coefficient and multiple regression analysis were utilized. The findings of the study were as follows. First, the coaching leadership of the child care center principals perceived by the child care teachers was above average, and their self-perceived organizational commitment was above average as well. Their self- perceived turnover intention was below average. Second, as a result of analyzing the correlation among the coaching leadership of the principals perceived by the child care teachers and their organizational commitment and turnover intention, it was found that there was a positive correlation between the coaching leadership of the principals and the organizational commitment of the child care teachers on the whole, and the coaching leadership of the principals was negatively correlated to the turnover intention of the child care teachers. Third, concerning the influence of the coaching leadership of the principals on the organizational commitment of the child care teachers, it seemed that organizational commitment became stronger when the child care center principals exerted better coaching leadership.

Characterization of Quinolone-Resistant Clinical Isolates of Escherichia coli in Korea

오유정,박서형,하미선,이연희 한국미생물학회 2002 The journal of microbiology Vol.40 No.2

Twenty-eight clinical isolates of Escherichia coli, composed of thirteen norfloxacin resistant isolates (MIC of >16 mg/ml), one intermediately resistant isolate (MIC of 8 mg/ml), and fourteen susceptible isolates (MIC of <4 mg/ml), were randomly selected to study the norfloxacin resistance mechanism and phylogeny in clinical isolates in Korea. Eleven norfloxacin resistant isolates and one susceptible isolate were multi-drug resistant (MDR). Every norfloxacin resistant isolate with MIC higher than 32 mg/ml had the same three mutations Ser83Leu and Asp87Asn or Tyr in GyrA and Ser80Ile in ParC. Whereas a resistant isolate with MIC of 16 mg/ml had three mutations but Asp87 in GyrA was replaced with Gly instead of Asn. The intermediately resistant isolate had the same two mutations in GyrA but a different mutation in ParC, Glu84Lys. Among the susceptible isolates, two isolates with MIC of 4 mg/ml had one mutation Ser83Leu in GyrA, and no mutation was found in the susceptible isolates. Resistant isolates showed higher efflux activity than the susceptible ones, with random amplification of polymorphic DNA (RAPD), six susceptible isolates form a separate group from the rest of the isolates.

한강(중랑천)의 오염도 측정

이계남,이은정,천청녀,하미선,홍현진,이연희 서울여자대학교 자연과학연구소 2002 자연과학연구논문집 Vol.14 No.-

한강의 오염도 측정을 위한 생물학적 지표로 대장균의 계절별 분포도를 측정하여 한강의 오염도를 예측하고, 상수원 및 레저용 수질에 적합한지를 파악하고자 하였다. 2000년 4월부터 2001년 3월까지 일년동안 매달 1-2회 한강 지류인 중랑천에서 대장균을 분리하였다. 우리나라의 수질 규격으로 식수원의 일반세균 규격은 100 CFU/㎖ 이고 대장균의 기준은 원수의 경우 50 CFU/㎖. 정수된 후에는 음성이어야 하며, 레저용수의 대장균 기준은 음성이고, 하수처리장의 경우 ㎖당 1,000개 이하이다. 본 실혐의 결과는 1년 동안의 중랑천의 수질이 상수원이나 레저용으로 부적당한 것으로 나타났는데, 4월과 1월에는 대장균이 검출되지 않아 상수원이나 레저용수로 적합할 것으로 나타났으나, 일반세균의 기준치인 100 CFU/㎖을 크게 벗어나 상수원이나 레저용으로 사용하기 부적당한 것으로 나타났다. 4월과 1월을 제외하고는 대장균이 검출되어 상수원이나 레저용으로 적합지 못한 것 으로 나타났고, 특히 9월과 10월에는 하수처리장의 기준치인 1,000 CFU/㎖에 비해 각각 1.140 CFU/㎖과 1.030 CFU/㎖ 이 검출되어 보다 엄격한 처리가 필요한 것으로 나타났다. 또한 최근에 심각한 문제로 대두되고 있는 항생제내성 세균의 환경중 분포경향을 파악하고자 하여 항생제 내성 대장균의 분포경향을 관찰하였다. Cephalothin 내성 대장균은 5월 이후로 증가되어 9월에 최대치를 보이다가 점차 감소하는 것으로 나타났고, norfloxacin 내성 대장균은 2000년 5월부터 9월까지 발견되었다가 그 이후로는 발견되지 않았다. 이러한 결과는 한강의 수질을 보전하기 위해서 중랑천 주변의 생활하수 및 축산폐수의 하수 처리를 엄격히 하여 수질을 보전해야 함을 시사하고 있다. In order to measure the contamination level of Han River, Escherichia coli, the biological indicator for the pollution, was observed to check the quality of water whether it is proper as the source for drinking water or recreational impoundment. Surface water of Joongrang stream, a branch of Han River, was collected monthly from April 2000 to March 2001. Guideline of E. coli for drinking water or recreational impoundment is negative and for sewage is less than 1,000 CFU/㎖. All year round, Joongrang stream was not proper for drinking water or recreation. CFUs of total bacteria were exceeded the guideline for source of drinking water, even though E. coli was not detected on April and January. Except these months, E. coli was detected especially during a period from September to October and CFUs of E. coli detected in Joongrang stream were 1,140 CFU/㎖ and 1,030 CFU/㎖ exceeding the guideline for sewage treatment. When CFU of antibiotic-resistant E. coli were counted in order to understand the influence of the misuse or overuse of antibiotics to the environmental pollution. Cephalothin-resistant E. coli were present all around the year except April and Febraury. And norfloxacin-resistant E. coli were detected from May to September. This showed that the Joongrang stream must be treated before it entered to the mainstream.

Purpose : The purpose of this study was to investigate the effects of flexibility and foot pressure on stretching exercise of hamstring muscle with and without pelvis neutral position. Methods : This study was performed on 30 subjects. Thirty subjects were divided into two group; hamstring passive stretching exercise with pelvis neutral position(n=15), hamstring passive stretching exercise without pelvis neutral position(n=15). Both of the group performed the exercise 4 times a week for 6 weeks. The data was analyzed by the paired t-test for comparing before and after changes of factors in each group and the independent t-test for comparing the between groups. Results : The results were as follows. There was statistically significant difference of before and after hamstring flexibility, foot pressure in pelvis neutral position(p<0.05). There was statistically significant difference of before and after hamstring flexibility, foot pressure without pelvis neutral position group(p<0.05). There was no statistically significant difference of between the two group in hamstring flexibility, foot pressure(p>0.05). Conclusion : As a result of this study, though no statistically significant difference of the between groups, we suggest that stretching exercise of hamstring muscle with pelvic neutral may be effective more than stretching exercise of hamstring muscle without pelvic neutral in flexibility, foot pressure.
