조영희,Cho, Young-Hee 한국지역사회간호학회 1999 지역사회간호학회지 Vol.10 No.2
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).

시니어에어로빅스에 참여한 여성노인의 신체적 자기개념과 심리적 웰빙감에 관한 연구
최연정 ( Yeon-jung Choi ),조영희 ( Young-hee Cho ) 한국리듬운동학회 2019 한국리듬운동학회지 Vol.12 No.1
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.

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.

Stock market prices, economic indices, trends and changes of social phenomena, etc. are categorized as time series data. Research on time series data has been prevalent for a while as it could not only lead to valuable representation of data but also provide future trends as well as changes in direction. We take a conventional model based approach, known as Markov chain modeling for the prediction on stock market prices. To improve prediction accuracy, we apply Markov modeling over carefully selected intervals of training data to fit the trend under consideration to the model. Another method we take is to apply clustering to data and build models of the resultant clusters. We confirmed that clustered models are better off in predicting, however, with the loss of prediction rate.
