The purpose of this correlational study was to offer strategies for nursing intervention to improve compliance with prenatal care. This study was designed to investigate degree of tardiness, correlation between hardiness and compliance with prenatal care. In research, the characteristic of hardiness has 1 teen demonstrated in resolving stressful situaltions and in adapting to overcome physical and psycho-logical tension. pregnancy is normal crisis process. Therefore, it is necessary to investigate degree of hardiness in normal pregnant woman and I think that concept of hardiness is able to become a new, important concept for prenatal care imtervention. The subjects were 388 normal pregnant woman over five months, who were selected from five university hospitals and two health centers in Taegu. Data were obtained using a convenience sample technique. Data collection was done from March 6 to June 18, 1992. The instruments used for this study were the Health Related Hardiness Scale developed by Pollock(1984) and compliance with a prenatal care scale developed by the author on the basis of results of a literature review. Data were analyzed using the SAS program for t - test, ANOVA, Scheffe test, Pearson correlation and stepwise multiple regression. The results are as follows : 1. The scores on the hardiness scale ranged from 35 to 210 with mean of 88.89. 2. The scores on the compliance with prenatal care scale ranged from 28 to 140 with a mean of 111.49. 3. There were significant differences between hardiness and obstetrical characteristic factors, duration of pregnancy, frequency of pregnancy, frequency of abortion(P .05). 4. There were significant differences between compliance with prenatal care and general and obstetircal characteristic factors, education and frequency of pregnancy(P .05). 5. Correlations between hardiness and compliance with prenatal care were all negative and significant(r=-.2276~ -.2930, P .000). Challenge of hardiness components was the low est (r= -.2814). 6. Significant differences between hardiness and compliance with prenatal care by group were as follows : Group 1 was the high est, whereas Group 8 was the lowest(F=5.47, P .0000). 7. Factors influencing compliance with prenatal care were : 1) Challenge was the main variable and accounted for 7.92% of the total variance. 2) Education and frequency of pregnancy accounted for an additional 2.74% of the total variance. From the above findings, this study suggests the following : 1) Considering the lack of empirical support, the theroy of hardiness needs to be evaluated. 2) A valid, reliable and culturally appropriate instrument needs to be developed for Health Related Hardiness Scale. 3) There is a need for further study of hardiness in a broad variety of populations. 4) There is a need for comparative study correlation between hardiness and compliance with prenatal care in woman with normal and abnormal pregnancies

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.

Construction safety remains an ongoing concern, and project managers have been increasingly forced to cope with myriad uncertainties related to human operations on construction sites and the lack of a skilled workforce in hazardous circumstances. Various construction fatality monitoring systems have been widely proposed as alternatives to overcome these difficulties and to improve safety management performance. In this study, we propose an intelligent, automatic control system that can proactively protect workers using both the analysis of big data of past safety accidents, as well as the real-time detection of worker non-compliance in using personal protective equipment (PPE) on a construction site. These data are obtained using computer vision technology and data analytics, which are integrated and reinforced by lessons learned from the analysis of big data of safety accidents that occurred in the last 10 years. The system offers data-informed recommendations for high-risk workers, and proactively eliminates the possibility of safety accidents. As an illustrative case, we selected a pilot project and applied the proposed system to workers in uncontrolled environments. Decreases in workers PPE non-compliance rates, improvements in variable compliance rates, reductions in severe fatalities through guidelines that are customized according to the worker, and accelerations in safety performance achievements are expected.

The purpose of this study was to identify blood and body fluids exposure, and factors influencing compliance with standard precautions among nurses. Participants consisted of 144 nurses in three general hospitals located in C province. Data were collected using a questionnaire that consisted of awareness, compliance, safety environment and attitude toward standard precautions. A total of 40.3% of participants had been injured by syringes or sharp tools that had already been used for patients within the last 1 year 1.01 times. Moreover, 22.9% of participants had been exposed to blood and body fluid of patients 1.06 times within the last 1 year. The mean score for compliance with standard precautions was lower than its awareness. There was a significant correlation between compliance and awareness and a safe environment. Multiple regression revealed an adjusted $R^2$ of 0.166 with the awareness score serving as the major predictor variable for compliance of standard precautions. Therefore, it is necessary to develop strategies to apply to systemic and continuous education regarding standard precautions and to foster a safe environment to enhance nurses' compliance with standard precautions.

The vibratory energy introduced into the external ear canal is changed by the mechanical factors of eardrum itself, the motility of ossicles, and the air cushion of tympanic cavity and the like. This study was designed to investigate the volume of middle ear cavity and mastoid air cell system as a factor of determining the accoustic impedance of middle ear system. The author studied how the increase in air volume of middle ear cavity effects on the acoustic impedance of middle ear system with dogs' ears and researched the correlation between the degree of pneumatization of temporal bones and the acoustic impedance of middle ear system by comparing the radiological findings of pneumatization (Law's and Towne's projection) with the acoustic impedance measurements with Madsen ZO 70. The result is as follows: 1 The tympanometric findings in control state revealed the curves of type A, and did not change in its configuration by the increase in the air volume of dogs middle ear system. 2. The static compliance of middle ear revealed a distinct and linear increase in proportion to the increase in air volume of middle ear system; the rate of increase was $0.05{\pm}0.02$ cc of static compliance per cc of air volume. 3. Authenticated in the above result and the tendency to increase in static compliance in proportion to the increase in the degree of pneumatization of temporal bones, there was significant regression equation between the degree of pneumatization of temporal bones (x variable) and the static compliance of middle ear system; $y=0.19x{\pm}0.16{\pm}0.05$ It is suggested that the difference in volume of middle ear system plays an important role in the change of the static compliance of middle ear, and the author concludes that the measurement of static compliance of middle ear has clinical value as diagnostic means of evaluating the degree of pneumatization of temporal bones along with some radiological examination.

A model of an advanced aircraft electric power system is developed and studied under variable-speed constant-frequency (VSCF) operation. The frequency of the generator's output voltage is varied from 400-Hz to 800-Hz for different loading scenarios. Power conversions are obtained using 12-pulse power converters. To reduce the harmonic contents of the generator output waveforms, two high-pass passive filters are designed and installed one at a time at the generator terminals. The performance of the two passive filters is compared according to their losses and effectiveness. The power quality characteristics of the studied VSCF aircraft electric power system are presented and the effectiveness of the proposed filter is demonstrated through compliance with the newly published aircraft electrical standards MIL-STD-704F.
