The purpose of this study is to conduct a retrospective chart audit of initial physical therapy evaluation to determine the incidence of sitting imbalance and its relationship to the side of weakness in hemiparetic patients. A review of the records of 36 patients revealed that the left side was predominantly affected in 17 patients and the right side in 19 patients. Ages, time since onset, and proportion of men and women did not difer between the left and right hemiparetic patients. About half patients(52.8%) could sit independently, but 64.7% of those with left-sided weak-ness and 31.6% of those with right-sided weakness could not. A chi-sequare analysis revealed a significant relationship between the side of weakness and independent sitting balance(p<0.1). Patients with left hemiplegia are more likely to have difficulty with independent sitting balance(p<0.1). Patient with left hemiplegia are more likely to have difficulty with independent sitting than patients with right hemiplegia, which may affect their progress in rehabilitation.

The statistical inference of Cronbach's alpha measure of internal reliability is known to be inaccurate when sample size is small and the assumption of normality is violated. In this paper, we describe the permutation method in which we compute resampling p-values for testing the difference between two or more independent Cronbach's alpha coefficients. When the over-all permutation test is significant, we also make pairwise post-hoc comparisons using permutaion method. The permutation tests for the equality of two independent Cronbach's alpha coefficients and three independent Cronbach's alpha coefficients are illustrated with an example analysis of survey data.

Extensions of the Kolmogorov convergence criterion and the Marcinkiewicz-Zygmund inequalities from independent random variables to conditional independent ones are derived. As their applications, a conditional version of the Marcinkiewicz-Zygmund strong law of large numbers and a result on convergence in $L^p$ for conditionally independent and conditionally identically distributed random variables are established, respectively.

The efficacy of chemotherapeutic agents on tumor cells has been shown to be modulated by tumor suppressor gene p53 and its target genes such as Bcl-2 family members (Bax, Noxa, and PUMA). However, various chemotherapeutic agents can induce cell death in tumor cells that do not express the functional p53, suggesting that some chemotherapeutic agents may induce cell death in a p53-independent pathway. Here we showed that etoposide can induce the similar degree of cell death in p53-deficient HCT 116 cells, whereas 5'-FU-mediated cell death is strongly dependent on the existence of functional p53 in HCT 116 cells. Further, we provide the evidence that etoposide can induce the cytochrome c release from isolated mitochondria, and etoposide-induced cytochrome c release is not accompanied with the large amplitude swelling of mitochondria. These data suggest that etoposide can directly induce the mitochondrial dysfunction irrespective of p53 status, and it may, at least in part, account for the p53-independent pathway in cell death induced by chemotherapeutic agents.

학교교육에서 확률의 독립사건의 정의 P(B | A)=P(B)가 직관적으로 설명할 수 없고 실생활과 다른 개념으로 잘 못 판단되어 질 수 있는 원인을 분석하고, 확률의 독립사건의 전형적인 문제와 정리들을 이용하여 실생활 개념과 정확하게 일치하고 직관적으로 설명 가능하다는 사실을 '구술형식'으로 논증한다. 확률과 통계 단원은 물리와 유사한 자연현상과 실생활에 더 밀접한 학문이므로 '수리식'을 보완한 '구술형식'의 보급은 불가피하다. 따라서 확률교육에서 오랜 기간 지속되어 온 '수리식'을 보완하여 '수리식'이 갖는 의미를 직관적으로 쉽게 이해 가능한 새로운 개념 습득 방법인 '구술형식'으로 설명할 필요성과 가능성을 제시한다. 본 논문을 통하여 그동안 학교교육이 확률의 독립사건 정의의 '수리식' 의미를 파악하지 못하여 확률교육의 맥이 막혀 있었다면 확률교육의 흐름에 새로운 지평을 여는 커다란 파급효과를 기대할 수 있다.

Purpose : The purpose of the study was to determine Effects of the ADL Group Study Program Training on Functional Independence and Quality of Life for the CNS Patients. Methods : Thirty patients with stroke were assigned to experimental and control group. During eight weeks, both group participated in the conventional physical therapy and only the experimental group added in the ADL Group Study program. Experimental group performed two a week for 8 weeks and both group were scored Mini-Mental State Examination-Korean version before the training. The data were analyzed with frequency, independent t-test, paired t-test using SPSS PC(ver.12.0). Results : The result of this study is as fallows : First, after eight weeks, the experimental group the significant improvement in Korean Activity Daily Living scale, washing(p<0.01), bathing, ambulation, toilet using(p<0.05) and decorating, the short distance transfer(p<0.05) in Korean Independent Daily Living scale, vitality(p<0.05) in Quality of Life score. Conclusion : These finding suggest that the ADL Group Study Program Training can be used to improve functional independent and quality of life for the CNS patients. Also, the result of this study can provide a reference for the successful therapeutic program in CNS patients.

The purpose of this study was to investigate the relationship of the cognitive levels and the science process skills based on the cognitive styles. The subjects of the study were 5-6th grade 790 students sampled by random cluster sampling method in three schools from large cities, small cities, and rural areas respectively. The results are as follows. 1) The field independent students showed significantly higher(p< 0.001) cognitive level than the field dependent ones. 2) The field independent group showed higher formation rate of subskills of the logical thinking skills than the field dependent groups. 3) It was found out that the field independent group attained significantly higher scores of science process skills than the field dependent group in 5th and 6th grade students. 4) The more cognitive levels became higher, the more science process skills were significantly higher(p< 0.001). 5) There were significant(p<0.001) differences among the science process skills for grade levels and three regions. And that there were not significant differences in the science process skills between males and females, 6) The science process skills of the field independent and the formal operational group could be acquired better scores in the science process skills than those who belong to another combinations.

Background: Severe perinatal asphyxia results in multiple organ involvement, neonate hospitalization, and eventual death. Purpose: This study aimed to investigate the predictive factors of death in newborns with hypoxic-ischemic encephalopathy (HIE) receiving selective head cooling. Methods: This cross-sectional descriptive-retrospective study was conducted from 2013 to 2018 in Fatemieh Hospital of Hamadan and included 51 newborns who were admitted to the neonatal intensive care unit with a diagnosis of HIE. Selective head cooling for patients with moderate to severe HIE began within 6 hours of birth and continued for 72 hours. The required data for the predictive factors of death were extracted from the patients' medical files, recorded on a premade form, and analyzed using SPSS ver. 16. Results: Of the 51 neonates with moderate to severe HIE who were treated with selective head cooling, 16 (31%) died. There were significant relationships between death and the need for advanced neonatal resuscitation (P=0.002), need for mechanical ventilation (P=0.016), 1-minute Apgar score (P=0.040), and severely abnormal amplitude-integrated electroencephalography (a-EEG) (P=0.047). Multiple regression of variables or data showed that the need for advanced neonatal resuscitation was an independent predictive factor of death (P=0.0075) and severely abnormal a-EEG was an independent predictive factor of asphyxia severity (P=0.0001). Conclusion: All cases of neonatal death in our study were severe HIE (stage 3). Advanced neonatal resuscitation was an independent predictor of death, while a severely abnormal a-EEG was an independent predictor of asphyxia severity in infants with HIE.

Objectives: The aim of this study was to analyze the change of lateral shift of Center of Pressure (CoP) according to the gait improvement in post-stroke hemiplegic patients and to investigate relationship between the change of motor grade and lateral shift of CoP. Methods: We measured the lateral shift of CoP and motor grade of eight post-stroke hemiplegic patients at the beginning of dependent gait and independent gait. Results: We found that CoP tended to be shifted to the non-affected side when patients started to walk independently. Furthermore, there was no relationship between the change of motor grade and lateral shift of CoP. Conclusions: This result may suggest it is more important to control the non-affected side than the affected side, at least until the beginning independent gait.
