In order to evaluate the factors related to therapeutic compliance of hypertensive patients in small and medium scale industry, the questionnaire survey and the blood pressure measurement were performed on 138 hypertensive patients who were reported to have C or $D_2$ result of hypertension at the workers' periodic health examination from March to November 2001. The contents of questionnaire included the informations of factors related to therapeutic compliance of hypertensive patients such as, age, sex, marital status, income, education levels, scale, occupation, work duration, smoking and drinking habits, exercise, family history, stress and A type personality, employer's concern, organizational culture, health status, awareness, knowledge and attitude toward the needs of hypertension treatment, and experience of health education. The results of the study were as follows: 1. The proportion of those who were compliant to the treatment of hypertension was 41.3% of subjects. Among small scale industry less than 50 employees, the rate of therapeutic compliance group was 27.5% and therapeutic noncompliance group was 72.5%. Among medium scale industry more than 50 employees, the rate of therapeutic compliance group was 60.3% and therapeutic noncompliance group was 39.7%. 2. Among therapeutic noncompliance group, 95.1% of patients were aware of the fact that workers have hypertension, and 77.8% of patients got 6-10 marks of hypertension related knowledge. For health education, 27.2% were experienced and 34.6% said no intention to participate. And for hypertension treatment, 9.9% said no need to get the treatment and 44.4% said have no idea whether get treatment or not. 3. The significant factors related to therapeutic compliance of hypertensive patients in small scale industry were work duration, A type personality(anger), health status, attitude toward the needs of hypertension treatment, and experience of health education. 4. The significant factors related to therapeutic compliance of hypertensive patients in medium scale industry were age, occupation, subjective symptom, attitude toward the needs of hypertension treatment, and experience of health education. In consideration of above findings, it was suggested that in order to improve the therapeutic compliance in small and medium scale industry hypertensives, it be necessary to change attitude, perception, knowledge and treatment of hypertension by various methods such as effective health education and individually consulting programs by occupational health professional.

To estimate nondestructively strength performances of laminated woods, 3-ply parallel- and cross-laminated wood specimens exposed under atmosphere conditions after bending creep test were prepared for this study. The effects of density of species, arrangement of laminae and lamination types on dynamic MOE obtained by flexural vibration were investigated, and regression analyses were conducted in order to estimate static bending strength and bending creep performances. Dynamic MOE of parallel-laminated woods showed 1.0~1.2 times higher values than static bending MOE, and those of cross-laminated woods showed 1.0~1.4 times higher values than static bending MOE. The degree of anisotropy of dynamic MOE perpendicular to the grain of face laminae versus that parallel to the grain of face laminae was markedly decreased by cross-laminating. There were strong correlations between dynamic MOE by flexural vibration and static bending MOE (correlation coefficient r = 0.919~0.972) or bending MOR (correlation coefficient r = 0.811~0.947) of 3-ply laminated woods, and the correlation coefficient were higher in parallel-laminated woods than in cross-laminated woods. It indicated that static bending strength performances were able to be estimated from dynamic MOE by flexural vibration. Also, close correlations between the reciprocal of dynamic MOE by flexural vibration and initial compliance at 0.008 h of 3-ply laminated woods were found (correlation coefficient r = 0.873~0.991). However, the correlation coefficient between the reciprocal of dynamic MOE and creep compliance at 168 h of 3-ply laminated woods was considerably lower than those between dynamic MOE and initial compliance, and it was hard to estimate creep compliance with a high accuracy from dynamic MOE due to the variation of creep deformation.

To evaluate aortic wall stiffness without influence of different background blood pressure, a new technique was developed and verified. At eight swine descending aortae, volume-pressure measurement was performed using custom-made system. Based on averaged pressure-volume curve, aortic distensibility index was formulated to evaluate aortic wall stiffness regardless of variable blood pressure and aortic size. The variability of aortic distensibility index by pressure change was compared with other parameters for wall stiffness evaluation. Subsequently, the aortic distensibility index was calculated at 100 contrast-enhanced EBCT data sets of normal volunteers in regular health screening program. The measured aortic distensibility index was compared with age, coronary calcium score, and aortic calcium score. Between 50 and 360 mmHg of blood pressure, the coefficient of variance of aortic distensibility index was 22.00% as comparing with 88.99% of classical compliance. Based on age, aortic distensibility index showed correlation coefficient of 0.55, whereas classical compliance showed 0.26. The correlation coefficient with modified aortic calcification was 0.43. Linear regression study revealed statistical significance of correlation coefficients. The aortic distensibility index, the method to evaluate aortic wall stiffness free from variable blood pressure and aortic size, was developed and verified with significant practical feasibility.

An automated system is developed to perform fatigue crack growth tests under constant effective stress intensity factor range ${\Delta}K_{eff}$. In the system, crack length and crack opening load are measured in real-time by using the unloading elastic compliance method. The system consists of two personal computers, an analogue electrical subtraction circuit, a stepping motor, a stepping motor driver, a PIO board, and the application software used to integrate the whole system. The performance of the developed system was tested and discussed performing constant ${\Delta}K_{eff}$ crack growth tests on a CT specimen of 7075-T6 aluminum alloy. The performance of the system is found to be strongly dependent on the accuracy of measurements of crack opening load. Besides constant ${\Delta}K_{eff}$ testing, the system is expected to be successfully applied for automation of various fatigue tests.

It depends on the joint configuration, dimensions and constraints of the joint whether the residual stress at the root of single-sided butt weld is tensile or not. Therefore, recommendation is generally made that high R ratio should be used in the fatigue test of welded joint in order to prevent excessively long life caused by compressive residual stress. In this research, the residual stress profile in butt weld joint was obtained through compliance method, using successive extension of a slot and measurement of the variation of strain during the slot extension. The residual stress profile was firstly assumed to be the linear summation of Legendre polynomials up to 9th order excluding 0th and 1st order. Strain variation on the surface was measured while the slot was being extended by cutting to find out the 8 unknown coefficients of each polynomial term. The cut was made by the electric discharge machine. It was concluded that the residual stress near the surface is positive valued, however, it turned into the negative value as soon as it passed through 2 or 3 mm of the depth.

Purpose: The purpose of this study was to identify the attributes of the concept, of psychological resistance to antihypertensive medication. Methods: The study was conducted in accordance with Walker and Avant's conceptual analysis process. We reviewed 47 related studies selected from 4 international and Korean databases including Medline, CINAHL, NDSL, and RISS to perform the analytical processes from January 1980 to September 2015. Results: The attributes of psychological resistance to antihypertensive medication include 1) reservation, 2) opposition, 3) denial, 4) refusal, and 5) seeking alternative therapy. The antecedents of the concept can be classified into patient factors such as reactance trait and knowledge deficit, provider factors, interpersonal factors, and environmental factors. The consequences of psychological resistance to antihypertensive medication are non-compliance, deterioration of the disease, developing complications, increased anxiety, and changes in life. Conclusions: The concept of psycho logical resistance to antihypertensive medication can provide guidance for the development of an intervention program that promotes the compliance to medication regimen of hypertensive patients. Further research needs to be done to develop a measurement tool for psychological resistance to antihypertensive medication.

When a robot is to have contact with its enviornment, such as a medi-care robot, it would be advantageous for the robot to have a high compliance. For this reason, a robot having not only a flexible link but also an actuator with compliance, is desirable. This paper is concerned with the position and vibration control of 1 degree of freedom flexible robot using a pneumatic artificial muscle actuator. The dynamics of the manipulator assumed to be and Euler-Bernoulli beam are derived on the basis of the linear mathematical modle. Although this pneumatic artifical muscle actuator has many merits for the compliance robot, it is difficult to make an effective control scheme of this system because of ths nonlinearity and uncertainty on the dynamics of the actuator. By designing a controller using .mu.-synthesis, robust performance against measurement noise, various modeling uncertainties on the dynamics of the servo valve, actuator and mainpulator, is achieved. The effectiveness of the proposed control method is illustrated through simulations and experiments.

Objective: The aim of this study was to examine the use of outcome-based observations within Assured Dairy Farm scheme (ADF), Soil Association Organic Standards (SA), and cross compliance (CC) farm assessment reports. Methods: A total of 449 ADF reports, 37 SA reports and 26 CC reports were analyzed and their objective comments categorized as either resource-based or outcome-based. Results: A mean of 61.0% of ADF questions were responded to with comments, in comparison to 25.0% of SA and, 21.0% of CC report questions. The SA and CC reports had significantly more outcome-based comments than the ADF (p<0.001). The assessors' tendency of choosing resource-based approach was revealed in the questionnaire results. Conclusion: Generally, the comments were comprehensive and contained professional judgements. Large numbers of comments provided in the ADF reports were mostly compliant and resource-based evidence, which serves as proof of assessment rather than aiding the certifying process. The inclusion of specific welfare outcome measures in the SA inspection likely increased the use of outcome-based comments in the reports, irrespective of whether the farm achieved compliance with a given standards. The CC scheme, on the other hand, focused on providing outcome-based evidence to justify noncompliant decisions.
