  • Purpose: This study was attempted to see the trends in breast cancer researches in Korea. Method: We collected a total of 94 articles associated with breast cancer and published in Korea from 1976 to August 2004 and analyzed the characteristics of those articles, the journals which published those articles in each year, the research designs, subjects, intervention effects in experimental studies, the subjects and concept distribution in comparative researches and themes of the articles. Result: 1. Articles published and associated with breast cancer have increased since 1990 and picked after 2000. 2. Most research designs are survey and correlation studies which are non-experimental research(70.2%) and next are experimental and qualitative researches. 3. In a total 17 articles which are experimental researches, intervention studies which use exercise programs are most(5 articles) and the next are education program, supportive nursing intervention, guided imagery, massage and rehabilitation programs. 4. In correlational researches, concepts such like social-psychological adaptation, partner support, health promotion behavior and family support are treated frequently. 5. Subjects in most comparative studies are patients with breast cancer and normal women. 6. Most nursing research themes are psycho/spiritual problems, 16 articles(17.0%). Conclusion: These results show that the researches related with breast cancer have actively increased and body functions and psycho-social variables have been improved through nursing intervention. Therefore, it seems that more systematic interdisciplinary studies and systematic complement are necessary for future breast cancer nursing researches.

  • Purpose: This study was done to evaluate the effects of foot reflexology on blood pressure, serum lipids, fatigue and self-efficacy in patients with hypertension. Methods: The research was done between June 23 and July 31, 2003 and the design was an experimental treatment design. The thirty-four participants were assigned to either an experimental group (18) or a control group (16), Foot reflexology was administered twice a week for 6 weeks to participants in the experimental group. Results: There was a significant decrease in systolic blood pressure and diastolic pressure in the experimental group compared to the control group. After the foot reflexology, total cholesterol and triglyceride levels for the experimental group did not decrease significantly compared to the control group. High density lipoprotein find low density lipoprotein levels also did not decrease significantly after foot reflexology Fatigue in the experimental group decreased significantly after foot reflexology. Self-efficacy in the experimental group did not decrease significantly after foot reflexology. Conclusion: The results show that foot reflexology is an effective nursing: intervention to decrease systolic blood pressure, diastolic blood pressure and to treat fatigue but not serum lipids. Therefore, blood cholesterol should be further evaluated with a larger group of participants and for a longer period.

  • This study compared the histological patency rates of anastomoses of the femoral artery. Twelve rabbits weighing about 2 kg were studied. Both the right and left femoral arteries were cut. The control group had no damage to the vessel, saline irrigation, and micro-anastomosis. Experimental group I had a crush injury to the vessel, saline irrigation, and micro-anastomosis. Experimental group II had a crush injury, saline irrigation, 100 U/ml heparin irrigation, and micro-anastomosis. Experimental group III had the same treatment as experimental group II plus the systemic application of 100 U/kg heparin iv. The histological patency rates were compared. The patency rates of the control group 30 min and 3 days after the anastomosis were 100 and 83%, respectively. The respective rates for experimental groups I and II 30 min and 3 days after the anastomosis were 100% in all cases. The respective rates in experimental group III were 100 and 83%. In this study, no significant correlation was observed between the patency rate and the effects of local irrigation or the systemic application of heparin on the microvascular anastomosis of the rabbit femoral artery. However, the patency rate tended to decrease concomitantly with an increase in surgery time. Increased bleeding was observed after the systemic application of heparin. Obvious damage to the crush-injured vascular endothelium was detected on histologic examination of the micro-anastomosed area. In addition, some vessels subjected to crush injury contained thrombi attached to the vascular endothelium. No preventive effect of heparin on thrombus formation was observed.

  • As technology advances swiftly and the lifespan of products becomes increasingly short, there is a demand to fasten the pace of research outcomes, product development, and market introduction. As a result, the researchers and developers need a computational experiment environment that enables rapid verification of the experiment and application of research findings. Such an environment must efficiently harness all available computational resources, manage simulations across diverse test scenarios, and support the experimental data collection. This research introduces the design and implementation of an experimental frame based on a microservice architecture. The experimental frame leverages scripts to utilize computing resources optimally, making it more straightforward for users to conduct simulations. It features an experimental frame capable of automatically deploying scenarios to the computing components. This setup allows for the automatic configuration of both the computing environment and experiments based on user-provided scenarios and experimental software, facilitating effortless execution of simulations.

  • Purpose: This study was to identify the effects of self-administered hand reflexology on level of fatigue in college student nurses during clinical practice. Method: A non-equivalent control group, quasi-experimental research with pre and post-test design was used. Forty-seven student nurses in clinical practice were assigned to either an experimental or control group. The experimental group performed self-hand reflexology for 10 minutes once a day during the 5 days of clinical practice. Results: 1. While there was a significant difference in degree of fatigue and fatigue scores in the experimental group over time, there was no significant difference between the two groups. 2. Vigor score for the experimental group was significantly higher than those of the control group during the 5 days except for day 5, but there was no significant difference between the two groups. 3, Levels of fatigue for the experimental group increased after 1 hour in the 1st post time, but there was no significant difference between the groups. Conclusion: Self-administered hand reflexology was not found to be an effective method for relieving fatigue for student nurses in clinical practice. Also physiological effects were not identified in this study, and so further research is needed.

  • This paper presents the results of experimental and numerical studies conducted to investigate the behavior of exterior reinforced concrete beam column joints (BCJ) strengthened by using carbon fiber reinforced polymer (CFRP) sheets. Twelve reinforced concrete beam-column joints (BCJ) were tested in an experimental program by simulating the joints in seismically deficient old buildings. One group of BCJs was designed to fail in flexure at the BCJ interface, and the second group was designed to ensure joint shear failure. One specimen in each set was -retrofitted with CFRP sheet wrapped diagonally around the joint. The specimens were subjected to both monotonic and cyclic loading up to failure. 3D finite element simulation of the BCJs tested in the experimental program was carried out using the software ABAQUS, adopting the damage plasticity model (CDP) for concrete. The experimental results showed that retrofitting of the shear deficient, BCJs by CFRP sheets enhanced the strength and ductility and the failure mode changed from shear failure in the joints to the desired flexural failure in the beam segment. The FE simulation of BCJs showed a good agreement with the experimental results, which indicated that the CDP model could be used to model the problems of the monotonic and cyclic loading of beam-column reinforced concrete joints.
