  • Purpose: This study was done to identify the effects of the BeHaS exercise program consisting of exercise, education, and cognitive supports on the hand strength, depression and life satisfaction in institutionalized elderly people with CVA. Method: A quasi-experimental design with an experimental group (n=18) and a control group (n=18) was used. The elders in the experimental group participated in the program once a week for eight weeks. Data were analyzed using descriptive statistics, Chi-square and t-test with SPSS/Win 18.0. Results: Hypothesis 1 was supported as the hand strength of the elders in experimental group significantly increased compared to those in the control group. Hypothesis 2 was also supported as depression scores for elders in the experimental group significantly decreased compared to those in the control group. Hypothesis 3 was supported as life satisfaction scores for elders in the experimental group significantly increased compared to those in the control group. Conclusion: The results of this study indicate that the BeHaS exercise program can play a useful role in improving depression and life satisfaction in institutionalized elderly people with CVA.

  • Purpose: The purpose of the study was to test the effects of music therapy on postoperative pain in patients with total hip replacement. Method: The research design was a nonequivalent control group pretest-posttest design. The subjects were composed of thirty patients with total hip replacement. Fifteen of them were assigned to the experimental group and fifteen to the control group. Fifteen minutes tailored music therapy was given to the experimental group during five consecutive days. The instruments used for this study were pain NRS(numerical rating scale). The data were analyzed using percent, mean, standard deviation, ${\chi}^2-test$ and repeated measure ANOVA using SPSS WIN 11.0. Results: Hypothesis 1 "The score of pain NRS of experimental group will be lower than those of control group" was accepted(F=15.945, p<.001). Hypothesis 2 "The frequency of PCA analgesics of experimental group will be fewer than those of control group" was accepted (t=-2.312, p=.028). Hypothesis 3 "The vital signs(pulse, systolic BP and diastolic BP) of experimental group will be different from those of control group" was rejected. Conclusion: This music therapy can be recommended as an efficient nursing intervention to reduce postoperative pain in patients with total hip replacement.

  • A study on Composing Unit Spaces of Apartment Houses according to the Differentiation in Lifestyle by survey on preferences. The purpose of this study is to propose composition models of unit spaces for 85m2 net area apartment houses by lifestyle types. This study set up a hypothesis that there is a critical divergence of preferences in composition types of unit spaces according to lifestyle. To prove the hypothesis, investigation on variable floor plans of apartments to extract spatial composition types of units and questionnaire survey on lifestyleand preferences for composition types were implemented. To extract several factors regarding, characteristics of lifestyle, factor analysis, was implemented for each variable. Cluster analysis was conducted to cluster interviewees by similarity of lifestyle. To identify and define how each factor reacts, ANOVA and cross tabulation analysis between factors and clusters were used. The type of spatial composition was analyzed by plane characteristic, spatial relation and spatial usability on the basis of apartment plate type. As a result, lifestyle was divided into three types: reasonable lifestyle, trend-seeking lifestyle and conservative lifestyle. As, the result of investigating characteristics for the type of spatial composition according to the type of lifestyle, preferred types and main districts were different. Therefore, the hypothesis was proved.

  • This study was to examine how consumption value of female consumers affects impulse consumption and purchase satisfaction when they buy bakery goods, present specific determinant factors that affect them, and identify its influencing factors. The survey was conducted with those who have bought bakery goods of female consumers in Seoul and Kyonggi area, using a convenience sampling method. After a total of 400 responses was collected, 366 responses were included for the multiple regression analyses in order to test the hypotheses. To summarize findings from this study, analysis of the first hypothesis showed that "emotional impulse buying," "stimulating impulse buying," "reminder impulse buying," and "situational impulse buying" among impulse buying factors in consumption value factors had positive effects. The second hypothesis analyzed that "emotional impulse buying," "stimulating impulse buying," and "situational impulse buying" gave positive impacts on "purchase satisfaction," while "reminder impulse buying" had no influence. Analysis of the third hypothesis demonstrated that "consumption value" had positive effects on "purchase satisfaction." These findings were significant to examine consumption value that show the consuming pattern of consumers, analyze influencing factors on impulse buying of female consumers, and further present marketing strategies used for advantageous tools with competing stores to bakery owners or marketers.

  • 일반적으로 웨이블릿 계수는 적은 수의 계수에 거의 대부분의 정보가 저장되어 있다. 이러한 웨이블릿 계수의 성긴 특성은 가우스 확률밀도 함수와 영점에서의 점 질량(point mass) 함수의 혼합으로 모델링될 수 있으며, 이 프라이어(prior) 모델에 대한 베이지안 추정법으로 잡음 제거를 수행한다. 본 논문에서는 가설-검증 기법을 이용하여 잡음 제거를 위한 파라미터를 추정하는 방법을 제안한다. 가설-검증은 관찰된 웨이블릿 계수의 분산에 적용되며, $X^2$-검증을 사용한다. 모의실험 결과를 통하여 본 논문의 방법이 직교 웨이블릿 변환을 사용한 최신의 잡음 제거 방법보다 대략 0.3dB 정도 우수한 PSNR(peak signal-to-noise ratio) 성능을 나타낸다.

  • Purpose: This study was conducted to verify the effects of an education program of restraints use on nurses' knowledge, attitude and nursing performance related to restraints use. Method: A quasi experimental study with a pre and post non-equivalent design was used. The subjects were nurses who met the selection criteria and worked in intensive care units of two university hospitals located at K-city, Gyeongbuk. Twenty nurses in A hospital were designated as the experimental group and 20 nurses in B hospital as the control group. Result: The first hypothesis which assumed that the experimental group would have higher scores of knowledge than the control group was supported(F=62.66, p=0.000). The second hypothesis which assumed that the experimental group would have lower scores of attitude toward using restraints than the control group was supported(F=23.77, p=0.000). The third hypothesis which assumed that the experimental group would have higher scores of nursing performance than the control group was supported(F=3.28, p=0.032). Conclusion: An education program for nurses' on the use of restraints needs to be introduced to decrease inappropriate use of restraints.

  • Purpose: This study was to identify the effects of Nei-Guan accupressure using a wrist band on postoperative nausea and vomiting after middle ear surgery. Methods: The study design was a nonequivalent control group non-synchronized posttest design. Forty patients were assigned into two groups of 20 patients, the wrist band group and the control group. In the wristband group, acupressure was applied with a wrist band on the P6 point at both wrists from 30 min before to 24 hr after anesthesia. Results: The 1st hypothesis 'Applied wrist band groups will have a greater reduction in the nausea & vomiting grades by INVR than the control group' was accepted (t=2.303, p=.028). The 2nd hypothesis 'The Applied wrist band groups will have a greater reduction in the occurrence of nausea & vomiting than the control group' was partly accepted. The 3rd hypothesis 'The applied wrist band group will have a greater reduction in injection of antiemetics for 24 hr. post anesthesia than the control group' was rejected. Conclusion: Acupressure on the P6 point using a wrist band is effective to alleviate nausea for middle ear surgery patients.
