Purpose: The purpose of this study was to examine self care compliance, family support, and depression in patients with congestive heart failure. Method: The participants were 105 outpatients with congestive heart failure. Data were collected using a questionnaire survey on self care compliance, family support, and depression. The collected data were analyzed using the SPSS Win 10.0 program. Result: 1. The total score for Self care compliance was 78.34 out of a possible 120 and was significantly high for people in ages between 70-79 years and people who were not employed. Exercise compliance was significantly high in men and classifications I & II of the NYHA class. Compliance with smoking and alcohol cessation were significantly high in women. Medication compliance was significantly high in the group which had experience with hospitalization. Family support was 31.75 out of a possible 40 and showed significant differences depending on spouse status and religion. Depression was 30.18 out of a possible 64 and was significantly high in the group whose educational level was above college graduation or who were under 65 years of age. Conclusion: The results suggest that nurses have to emphasize smoking and alcohol cessation for men, exercise for women and total self care compliance for patients under 65 years of age.

Purpose: The purpose of this study was to explore differences in health belief by compliance level with breast self-examination (BSE) and the predictors of BSE compliance among women. Method: Using a convenience sampling method, 163 women were selected for the sample. Data were measured for each participant during the period between December 2008 and February 2009, and analyzed by chi-square test, t-test, Kruskal-Wallis test with post hoc, and logistic regression analysis. Samples were categorized into three groups by the compliance level of BSE for the last 6 months: Never-performers (i.e, women who had never performed BSE), irregularly-performers (i.e, women who performed BSE at least once), and regularly-performers (i.e, women who performed monthly BSE). Result: Significant differences were reported among never-performers, irregularly-performers and regularly-performers correlated to age, level of education, mammography, ultrasonography, clinical examination, benefit, and confidence. There was no significant difference between irregularly-performers and regularly performers. The significant factor influencing compliance with BSE was 'confidence', which explained 33.7% of the variance in compliance with BSE. Conclusion: Women who had more confidence in their ability to perform BSE were more likely to practice BSE. It is necessary to develop the strategy to enforce woman's confidence in complying with BSE.

This paper presents a new concept to implement and to control of tactile reproduction simulator by implementation of compliance emulator system. Compliance emulator system is a kind of levitation system using magnetic force. In the compliance emulator system, a floated plate moves vertically. When an external force is applied to the plate, the system produces a controlled reaction force by using 6 electromagnet. For the control, a LVDT displacement sensor and PD control method is used.

Purpose: The purpose of this study was to identify relationships between HbA1c (Glycosylated Hemoglobin), WHR (Waist hip ratio), WTR (Waist thigh ratio) and compliance in elderly diabetes mellitus patients aged 65 years or over. Method: We conducted a survey and measured HbA1c, WHR, WTR in a total of 180 elderly patients with diabetes from 5 May 2014 to 30 May 2014. The data were analyzed by t-test, ANOVA, and Pearson's Correlation Coefficient using the SPSS program. Results: There were no significant differences in diabetes-related characteristics for HbA1c, WHR and WTR. However, patients with a family history had low compliance scores (p=.004). Furthermore, patients who visited the hospital regularly had higher compliance scores than patients who visited hospital when they were sick (p<.001). Patients with diabetic complications had low treatment compliance scores (p=.001). In addition, WHR and WTR (r=0.47, p<.001). and WHR and compliance (r=0.15, p=.045) showed positive correlation. Conclusion: For elderly diabetes mellitus patients, diabetes-related characteristics and compliance were highly related, so it is necessary to improve compliance for managing diabetes mellitus.

An electro-hydraulic manipulator using hydraulic actuators has many nonlinear elements, and its parameter fluctuations are greater than those of an electrically driven manipulator. So it is relatively difficult to obtain stable control performance. In this report, we applied disturbance estimation and compensation type robust control to all axes in a 3-link electro-hydraulic manipulator. From the results of experiment, it was confirmed that the performance of trajectory tracking and attitude regulating is greatly improved by the disturbance observer, which model is the same for each axis. On the other hand, for the autonomous assembly tasks, it is said that compliance control is one of the most available methods. Therefore we proposed compliance control which is based on the position control by disturbance observer for our manipulator system. To realize more stable contact work, the states in the compliance loop are feedback, where not only displacement but also velocity and acceleration are considered. And we applied this compliance control to Peg-in-Hole insertion task and analyzed mechanical relation between peg and hole. Also we proposed new method of shifting the position of end-effector periodically for the purpose of smooth insertion. As a result of using this method, it is experimentally confirmed that Peg-in-Hole insertion task with a clearance of 0.05［mm］can be achieved.

This paper introduces the structural design optimization of a high speed machining center using multi-step optimization combined with G.A.(Genetic Algorithm) and Weighted Method. In this case, the design problem is to find out the best design variables which minimize the static compliance, the dynamic compliance, and the weight of the machine structure simultaneously. Dimensional thicknesses of the thirteen structural members of the machine structure are adopted as design variables. The first step is the cross-section configuration optimization, in which the area moment of inertia of the cross-section for each structural member is maximized while its area is kept constant The second step is a static design optimization, In which the static compliance and the weight of the machine structure are minimized under some dimensional and safety constraints. The third step IS a dynamic design optimization, where the dynamic compliance and the structure weight are minimized under the same constraints. After optunization, static and dynamic compliances were reduced to 62.3% and 95.7% Eorn the initial design, while the weight of the moving bodies are also in the feaslble range.

J-R curve tests were performed on 1T compact specimens of SA516 Gr. 70 carbon steels under reverse cyclic loading. A Direct-Current Potential Drop (DCPD) method, one of the nondestructive techniques to detect flaw of structure, is being increasingly used for monitoring crack initiation and stable crack growth in typical fracture mechanics specimens for J-R testing. In many aspects this method is simpler than the unloading compliance method. The objective of this paper is to evaluate the J-R Curve according to the crack length measurement techniques under reverse cyclic loading. In order to prove the reliability and repeatability of the DCPD method, the crack length measured by using DCPD method was compared to one determined from unloading compliance. Consequently, this DCPD method correlated well with J-R curves and crack extension measurements determined from unloading compliance method.

This paper was undertaken to develop the fracture toughness testing method using small and single specimen compared to the conventional method in evaluating elastic-plastic fracture toughness of the superconducting magnet structural material at cryogenic temperature. The elastic-plastic fracture toughness test was conducted by using the unloading compliance method recommended by ASTM E813-89 to accomplish the above purpose. And, the 20% side-grooved 0.5TCT and 1TCT specimens were used to evaluate the fracture toughness by using as possible as miniaturized CT specimen. The unloading compliance method was a very useful method in evaluating elastic-plastic fracture toughness at cryogenic temperature. It could be taken valid fracture toughness values by using 20% side-grooved 0.5TCT specimen recommended by ASTM E813-89.

The aim of this paper is to clarify the structural compliance of the constrained flexible manipulator and to develop the force control algorithm by using the compliance of the links. The proposed structural compliance control consists of the position control to utilize a flexible manipulator model (considering the compensation for the elastic deflection of links) and the passive force control to utilize the rigid manipulator model (without considering the compensation for the elastic deflection of links). We present the experimental results for the case when applying the only position control, and when applying the structural compliance control. Finally, a comparison between these results is presented to show the performance of our method.
