  • This study was undertaken to evaluate the effect of long-term(6 Month) aquatic exercise through home nursing care demonstration on body weight, body fat, pain, muscle strength, self-efficacy and quality of life. Twenty-one women with rheumatoid arthritis were enrolled in the study. The sample was restricted to women in order to increase homogeneity. All patients were stable medication regimens in rheumatism center. The data was collected from October, 1994 to November, 1995. The data were analyzed Mean, Standard Deviation, $x^2$ Test, Mann-Whitney U-Wilcoxon Rank Sum W Test, Wilcoxon Matched-pairs signed-ranks test using SPSS $pc^+$ program. The results of this study were as follows : 1. There was no significant difference between the control and the experimental group on body weight. 2. There was no significant difference between the control and the experimental group on body fat. 3. There was no significant difference between the control and the experimental group on pain(RAI). 4. There was no significant difference between the control and the experimental group on muscle strength. 5. There was no significant difference between the control and the experimental group on quality of life. But in the experimental group, finding from additional analysis showed significant difference in the score of quality of life between pre and post experiment. 6. There was no significant difference between the control and the experimental group on self-efficacy. The findings in this study were not support the positive effect of long-term aquatic exercise in women with rheumatoid arthritis. A further study is necessary to determine the pure effect of aquatic exercise except the effect of home nursing care.

  • The purpose of this study was to explore the determinants of induced abortions of married women in Korea, with focus on the socioeconomic factors including fertility behaviors and ideation regarding family values. Data from the 2000 Korea National Fertility Survey by Korea Institute of Health and Social Affairs were used for the research. In particular, the women´s fertility history from 1998 to 2000 was served as the main data for this study. Among 1,901 pregnancies in total, 1,612 pregnancy outcomes were selected for the final analysis. Chi-square test, Wilcoxon rank sum test and multivariate logistic regressions were employed to identify influential factors on induced abortions. According to the results, working women was more likely than those who did not work to terminate their pregnancy by an induced abortion. Women´s religion did not show any significant impact on an induced abortion. A pregnant woman already having more than or equal to two children was very likely to choose an induced abortion. Likewise, those in unwanted pregnancy showed high probability of induced abortions. However, contrary to what we believe, it turned out that the number of sons did not affect the choice of induced abortions.

  • Purpose: 본 연구는 단하지 보조기를 사용하는 뇌졸중환자의 시-거리 보행변수에 대한 청각신호 효과에 대한 알아보고자 하는 것이다. Methods: 9명의 뇌졸중환자가 본 연구에 참여하였으며 대상자는 보조기 착용이 없는 경우, 기존 보조기 착용의 경우 그리고 청각신호 보조기 착용의 경우에 각각 시-거리 보행 변수에 대해 측정하였다. 8대의 동작분석 카메라 시스템(Motion Analysis Corporation, Santa Rosa, USA)을 사용하여 시-거리 보행 변수를 측정하였으며 Wilcoxon rank sum test을 이용하여 양하지의 대칭성을 분석하였고 Friedman test를 사용하여 다른 보조기 사용에 따른 효과를 알아보았다. Results: 청각 신호 보조기의 경우, 손상측과 비손상측의 보행속도, 활보장 그리고 분속수가 대칭적으로 되었다. 손상측의 경우, 단하지 보조기를 착용하였을 때가 착용하지 않았을 때보다 대체적으로 보행 변수들이 증가하였다. 청각 신호 단하지 보조기를 착용하였을 때 손상측 하지의 보행 속도, 활보장, 보장, 양하지 지지 시간이 증가하였고 단하지 지지 시간은 감소하였다. Conclusion: 청각 신호 단하지 보조기 착용 시 보행 속도, 활보장, 보장은 보조기를 착용하지 않았을 때보다는 증가하였으나 청각 신호 단하지 보조기와 기존 단하지 보조기 착용 사이에는 차이가 없었다. 하지만, 본 연구의 결과는 청각 신호 단하지 보조기가 뇌졸중 환자의 시-거리 보행 변수를 개선할 수 있음을 보여주었고 앞으로 다양한 보행 변수들에 대한 연구가 필요하다고 생각한다.

  • Purpose: The purpose of this study was to investigate the degree of LUTS (Lower Urinary Tract Symptoms) and factors affecting LUTS in patients with prostate cancer. Methods: Fifty-four patients with prostate cancer participated and they completed a structured questionnaire at a hospital in Seoul. The LUTS level was measured by using the International prostate symptom score (1992) and the data were analyzed by Wilcoxon rank sum test and Kurskal-Wallis test. Results: Most subjects obtained a higher than moderate LUTS score. The participants who had a lower perceived health status and did not drink alcohol were more likely to had a lower LUTS score than other patients who had higher perceived health status and drink alcohol. In addition, eye diseases were significantly associated with the LUTS score. In LUTS, all the patients received higher IPSS-QOL (International prostate symptom score quality of life) and frequency, nocturia. Conclusion: For proper nursing care related to LUTS, nurses should focus on the factors identified when performing nursing assessments and should develop nursing intervention programs for symptoms management.

  • Purpose: This study aimed to identify the level of complete knowledge about hand hygiene indications among nurses working at integrated nursing care service wards. Methods: A total of 127 nurses in eight integrated nursing care service wards completed structured sheets while observing a video based on six scenarios developed by the research team. Complete knowledge level was calculated as the percentage (%) of participants who responded correctly to all questions among participants. Complete knowledge levels according to the scenarios were calculated and compared according to general characteristics using the chi-squared test or Wilcoxon rank-sum test. Results: The complete knowledge level for each scenario ranged from 7.9% (scenario 6) to 42.5% (scenarios 4 and 5), and no one had complete knowledge of all scenarios. Only 3.1% of participants demonstrated complete knowledge in more than four scenarios, and 26.0% had complete knowledge of four or more hand hygiene moments. Complete knowledge level per scenario did not differ depending on work experience at hospitals and study wards, or prior hand hygiene training in the last year. Conclusion: As the complete knowledge level regarding hand hygiene moment is very low, it is suggested that regular hand hygiene training should be provided to nurses using video media that reflect real nursing tasks. Thus, they can acquire complete knowledge of when hand hygiene is needed or not during complex nursing work situations.

  • Quantum-inspired Genetic Algorithm (QGA) is a probabilistic search optimization method combined quantum computation and genetic algorithm. In QGA, the chromosomes are encoded by qubits and are updated by quantum rotation gates, which can achieve a genetic search. Asset-based weapon target assignment (WTA) problem can be described as an optimization problem in which the defenders assign the weapons to hostile targets in order to maximize the value of a group of surviving assets threatened by the targets. It has already been proven that the WTA problem is NP-complete. In this study, we propose a QGA and a hybrid-QGA to solve an asset-based WTA problem. In the proposed QGA, a set of probabilistic superposition of qubits are coded and collapsed into a target number. Q-gate updating strategy is also used for search guidance. The hybrid-QGA is generated by incorporating both the random search capability of QGA and the evolution capability of genetic algorithm (GA). To observe the performance of each algorithm, we construct three synthetic WTA problems and check how each algorithm works on them. Simulation results show that all of the algorithm have good quality of solutions. Since the difference among mean resulting value is within 2%, we run the nonparametric pairwise Wilcoxon rank sum test for testing the equality of the means among the results. The Wilcoxon test reveals that GA has better quality than the others. In contrast, the simulation results indicate that hybrid-QGA and QGA is much faster than GA for the production of the same number of generations.
