The purpose of this study was to explore the degree of stress in caregivers caring for CVA patients and the level of daily living performance of CVA patients. The subjects for the study were caregivers of 112 CVA patients who enter a hospital or out-patient-department (OPD) at two Oriental medical hospital in Jeonbuk province. The survey instruments used in this study were Kang's ADL check list for daily living performance of patients and Choi's 4 sore scale for stress of caregivers. The survey was conducted from July 4th to August 30th in 1999. The survey results were analyzed with the Statistical Package for Social Science(SPSS) program and can be summarized as follows: 1. The level of daily living performance for the CVA patients was: 1) complete dependence (M=14.9, 13.1%), 2) complete independence (M=23.6, 20.9%), 3) incomplete independence (M=23.9, 21.0%), 4) incomplete dependence (M=26.6, 25%), 5) dependence and independence (M=23.0, 20.0%). The items for with there was a high level daily living performance were: 1) drinking (M=3.62), 2) eating(M=3.25). 3) position returning (M=3.18) : and the items for which there was a low level of daily living performance were: 1) ascending and descending stairs (M=2.08), 2) walking (M=2.47), 3) dressing and undressing trousers (M=2.55). 2. Degree of caregiver stress was: Mean=2.39 at 40 score. The items for which was a high level caregiver stress were: 1) medical fee (M=3.25), 2) being handicapped or recurrence (M=3.02) : and the items for which there was a low level of caregiver stress were: 1) discontinuity of patient's treatment (M = 1.98). 2) change of home atmosphere caused by patient's disease (M = 1.98), 3) desire of patient's knowing about disease (M= 1.99). 3. There was statistically significant difference in the degree of caregiver stress according to the following caregiver's demographic characteristics: education level (F=3.52, P=0.03). change of caregiver (F=5.41. P=0.02). 4. There was a statistically signifiant difference in the level of daily living performance according to the CVA patients demographic characteristics: patient's paralytic status (F=4.48, P=0.01), duration of disease (t=2.76, P=0.03). 5. There was significant difference in degree of caregiver stress according to the CVA patient's demographic characteristics: CVA status (F=4.75, P=0.01). 6. There was statistically significant difference in the degree of caregiver stress according to the level of daily living performance in CVA patients(r=-0.482, P<0.00).

The purpose of study was to examine the physical self-conception and psychological well-being of elderly women participating in senior aerobics. The subjects of this study were 193 people in the elderly welfare center and seniors participating in senior aerobics in the northern part of Gyeongido (Uijeongbu, Yangju, Dongducheon, Pocheon). The survey tool used the physical self-concept scale developed by Kim Byung-Joon(2001) and the psychological well-being scale developed by Hwang Young-Joon(2009) as a questionnaire. The 5-point Likert scale was used. The collected data were analyzed by One-way ANOVA, correlation analysis, and multiple regression analysis. The results of this study were as follows ; First, there was no difference in age, physical self-concept and psychological well-being according to general characteristics(age, exercise duration, frequency, intensity). Second, the correlation between physical self-concept and psychological well-being was positively correlated. Third, physical self-concept is related to psychological well-being. Among the sub-factors of physical self-concept, appearance and overall physical factors influenced sub-factors of psychological well-being. The physical self-concept of elderly women who participated in senior aerobics partially affected psychological well-being.

캄보디아의 선거제도와 정당체계의 상호관계

조영희(Cho Young Hee) 한국정치학회 2009 한국정치학회보 Vol.43 No.1

본 연구는 캄보디아의 1993년 선거 이후에 의회와 정부 내에서 집권여당인 캄보디아인민당(CPP)의 정치권력이 더욱 공고화되어 온 이유를 선거제도와 정당체계의 수준에서 논의하였다. 선거제도가 정당체계에 미치는 영향뿐만 아니라, 정당체계 수준의 특성이 선거제도의 형성과 실질적인 파급효과에 어떠한 영향을 미치는가를 모두 살펴보았다. 이러한 연구방법은 선거제도와 정당체계를 상호간에 영향을 주고받는 독립변수이자 종속변수로 간주한다. 연구결과 1997년에 개정된 선거법에서 비례대표제 의석할당방식 중에서 동트식을 채택한 이후 매 선거마다 집권여당인 캄보디아인민당에게 유리한 정치적 왜곡효과가 발생한 것이 발견되었다. 그것은 이론적으로 동트식이 비례대표제 내에서는 가장 비례성이 낮다는 점 외에도 실제로 다양한 선거구의 크기별로 비례성에 큰 격차가 나타났기 때문이다. 그 결과 선거제도는 정당체계의 수준에서 볼 때, 외형상 다당제를 형성해오고 있지만 실질적으로는 1당이 장기 집권하는 “1당우위정당 체계”(predominant party system)를 형성하는 데 주요한 요인이 되었다. 그러나 동일한 선거제도라고 할지라도 그것이 적용되는 정치적ㆍ사회적 맥락 속에서 다른 결과가 초래될 수도 있다. 일례로 정당이 유권자의 지지를 얻는 방식이 민주적이라면 득표를 의석으로 전환시키는 과정에서 정치적 왜곡효과가 크게 나타나지 않을 수도 있다는 것이다. 이러한 맥락에서 캄보디아의 유동적인 정당정치, 정당체계 수준에서의 낮은 경쟁성과 대표성이 선거제도의 형성과정에 영향을 미치고 정치적 왜곡효과를 극대화시켰던 주요 배경이라고 주장하였다. This study analyzes the reasons for the strength of the CPP (Cambodia People’s Party) in parliamentary and governmental elections since 1993. The focus is on the electoral system and the party system in Cambodia, including not only the effects of the electoral system on the party system but also the effects of the party system on the electoral system. They act both as dependent and independent variable to each other. The transformation of the electoral system in 1997 to apply the d’Hondt system for the allocation of proportional seats resulted in a distortional effect that provides the CPP with more seats in parliament. This is related to the interaction of seat allocation rules and varying district magnitude in Cambodia. As a result, a predominant party system is emerging since the 1998 elections. However, in changed political and social contexts, the results can be different in spite of the same electoral system. If parties mobilize the support from the electorate in a democratic way, the distortional effect of electoral system can be relatively lower. In this context, fluid party politics, low competitiveness and the lack of representativeness of the party system are the main reasons that affect the transformation of electoral system and increase the distortional effects of electoral system in Cambodia.

초등학교 3, 4, 5학년 의미단위 끊어읽기와 빈칸채우기로 살펴 본 묵독유창성 비교연구

조영희 ( Cho Young Hee ),고혜정 ( Koh Hye Jung ),김동일 ( Kim Dong Il ) 서울교육대학교 초등교육연구소 2017 한국초등교육 Vol.28 No.3

묵독유창성이란 글을 소리내지 않고 눈으로 읽는 빠르고 정확한 자동적 해독과정이라 할 수 있으며 초등학교 고학년에서는 학교 수업현장에서 음독유창성보다 묵독유창성 활용이 급증한다. 묵독유창성은 빈칸채우기와 의미단위 끊어읽기로 측정할 수 있으며, 본 연구에서는 이 두 검사를 통해 측정된 묵독유창성이 학년수준별로, 성취수준별로 읽기이해력에 어떠한 영향을 미치는지를 알아보고자 하였다. 그 결과, 묵독유창성은 학년이 높아짐에 따라 계속적으로 발달하며, 고성취 학생들은 의미단위 끊어읽기가, 저성취 학생은 빈칸채우기와 의미단위 끊어읽기의 묵독유 창성이 읽기이해에 영향을 주고 있는 것으로 나타났다. 또한 3학년은 다른 학년보다 묵독유창성이 읽기이해를 설명하는 변량이 높게 나타났으며, 4학년과 5학년은 저성취 집단에서만 빈칸채우기형태의 묵독유창성이 읽기이해에 영향을 주고 있는 것으로 나타났다. 이상의 연구결과를 통해 초등학교 3, 4, 5학년 학생들의 읽기이해와 묵독유창성 능력에 관해 논의하였다. Silent reading fluency is the ability to read a text accurately, quickly and silently. More recently, silent reading fluency is more important in upper grades of elementary than oral reading fluency because they have to read silently for learning in the class. Silent reading fluency is measured using maze test and reading sense group. The purpose of this study is to analyze the effect silent reading fluency on reading comprehension by grade level and reading comprehension achievement level. As a result, silent reading fluency increases with grades. And sense group reading ability affects on reading comprehension of high achieving students. In order hands, both sense group reading and maze affect on reading comprehension of low achieving students. Also, silent reading fluency affects reading comprehension of both high achieving and low achieving third grade. However, silent reading fluency affects reading comprehension of only low achieving students in fourth and fifth grade. Implication of these results and suggestions for follow-up studies were discussed.

CRM을 위한 은닉 마코프 모델과 유사도 검색을 사용한 시계열 데이터 예측

조영희(Young-Hee Cho),전진호(Jin-Ho Jeon),이계성(Gye-Sung Lee) 한국컴퓨터정보학회 2009 韓國컴퓨터情報學會論文誌 Vol.14 No.5

시계열의 예측에 대한 문제는 오랫동안 많은 연구자들의 연구의 대상이었으며 예측을 위한 많은 방법이 제안되었다. 본 논문에서는 은닉 마코프 모델(Hidden Markov Model)과 우도(likelihood)를 사용한 유사도 검색을 통하여 향후 시계열 데이터의 운행 방향을 예측하는 방법을 제안한다. 이전에 기록된 시계열 데이터에서 질의 시퀸스(sequence)와 유사한 부분을 검색하고 유사 부분의 서브 시퀸스를 사용하여 시계열을 예측하는 방법이다. 먼저 주어진 질의 시퀸스에 대한 은닉 마코프 모델을 작성한다. 그리고 시계열 데이터에서 순차적으로 일정 길이의 서브 시퀸스를 추출하고 추출된 서브 시퀸스와 작성된 은닉 마코프 모델과의 우도를 계산한다. 시계열 데이터로부터 추출된 서브 시퀸스 중에서 우도가 가장 높은 시퀸스를 유사 시퀸스로 결정하고 결정된 부분 이후의 값을 추출하여 질의 시퀸스 이후의 예측 값을 추정한다. 실험 결과 예측 값과 실제 값이 상당한 유사성을 나타내었다. 제안된 방법의 유효성은 코스피(KOSPI) 종합주가지수를 대상으로 실험하여 검증한다. Prediction problem of the time-series data has been a research issue for a long time among many researchers and a number of methods have been proposed in the literatures. In this paper, a method is proposed that similarities among time-series data are examined by use of Hidden Markov Model and Likelihood and future direction of the data movement is determined. Query sequence is modeled by Hidden Markov Modeling and then the model is examined over the pre-recorded time-series to find the subsequence which has the greatest similarity between the model and the extracted subsequence. The similarity is evaluated by likelihood. When the best subsequence is chosen, the next portion of the subsequence is used to predict the next phase of the data movement. A number of experiments with different parameters have been conducted to confirm the validity of the method. We used KOSPI to verify suggested method.

In order to satisfy the self-sufficiency of plasma, the Korean Red Cross has opened many blood donation offices, where many apheresis machines have been installed for plasmapheresis. It is very important for the donors to feel comfortable on plasmaphersis because they may donate frequently. Plasma hemoglobin can cause problem to both donors and patients. In this study, plasma hemoglobin was compared between pheresis machines (Fenwal Autopheresis C system vs Fenwal Autopheresis C system mini instrument vs Haemonetics Mobile collection system vs Haemonetics Plasma collection system). Plasma hemoglobin in FFP was also measured. Amount (Mean ± SD) of plasma hemoglobin by Auto-C and Mini Auto-C of Fenwal`s was 2.87 mg/dL ± 2.02 mg/dL and 3.86 mg/dl ± 2.77 mg/dL respectively. And that of PCS and MCS was 2.86 mg/dL ± 1.56 mg/dL and 1.94 mg/dL ± 2.58 mg/dL respectively. There was no statistically significant difference between machines of the same companies. However amount of free hemoglobin was lower in plasma collected by Haemonetics (p=0.013) even though amount of free hemoglobin generated by each machines of both companies was with in the normal range of human plasma hemoglobin. Amount of free hemoglobin in FFP was in the middle between that of Fenwal`s and Haemonetics`. High level of free hemoglobin by Fenwal`s is thought to be caused by membrane filter that is installed to prevent red cell contamination from plasma. This results dosen`t mean that red cell itself is more contaminated in Fenwal`s. Considering that amount of free hemoglobin in all the plasma was within the normal range, it can be concluded that all the machines tested in this study can be used doesn`t cause any problem occured by free hemoglobin.
