Purpose: This study was to examine the relationship between perceived the past parent-child relationship(caring and overprotection), present parent-child attachment (communication, confidence, alienation) and self-concept of woman college students. Method: The data was collected from March 15 through 26, 2004. The subjects in this study were 395 students who attended universities located in N and T city. The data analyzed using with SAS program, and analysis of variance, Pearson correlation analysis, multiple regression. Results: Concerning the connection of demographic variables to the past parent-child relations(caring and overprotection), current parent-child attachment(communication, confidence, alienation) made a Significant difference in economic family standard (p<.05), educational level of their fathers(p<.01), birth of order(p<.05) and whether or not they lived with their parents under the same roof(p<.05), past experience of living with their parents under the same roof(p<.01). The relationship of the past parent-child relations(caring and overprotection), and current parent-child attachment(communication, confidence, alienation) made a significant difference to communication(p<.001), confidence(p<.001), alienation(P<.001). The correlation among the past parent-child relations(caring and overprotection), current parent-child attachment(communication, confidence, alienation) and self-concept, caring had significantly positive correlation(p<.001) with communication(r=0.631), confidence(r=0.669) and self-concept(r=0.520), and had significantly negative correlation(p<.001) with overprotection(r=-0.369), alienation(r=-0.531). The overprotection had Significantly negative correlation(p<.001) with communication(r=-0.303) confidence(r=-0.369) and self-concept(r=-0.292), and that had significantly positive correlation(p<.001) with alienation (r=0.275). Overall, the past parent child relations(caring and overprotection) made a 28.2% prediction of self-concept, and the current parent-child attachment(communication, confidence and a sense or alienation) made a 46.1% prediction or self-concept, and their predictability was all significant. Conclusion: This study suggests that perceived the past parent-child relationship(caring and overprotection) is significant influencing factors on present parent-child attachment(communication, confidence, alienation), self-concept. Therefore, nursing strategy is needed to manage these revealed factors.

The purpose of this study was to find correlation between the Berg Balance Scale which is most commonly used and the equilibrium scores from Smart Balance Master System which is used for the test of the balance ability for the patients with chronic hemiparetic stroke to predict their falling risk though examining the postural control. Twenty-two subjects who had first stroke participated in this study. Participants were measured the Berg Balance Scale and the Smart Balance Master System. The study found that there was a significant correlation between the Berg Balance Scale and the equilibrium scores from Smart Balance Master System. And there was no significant correlation at all "eye-closed and sway of surfaces" in the 6 conditions of Smart Balance Master System and there was a significant correlation with over median in the other 5 conditions. The study was uncovered that there was no meaningful correlation between the Berg Balance Scale and "eye-closed and sway of surfaces" because chronic hemiparetic stroke patients heavily relied on their vision to maintain their balance ability and the Berg Balance Scale did not properly exam it. Thus to predict their falling risk in clinical practice for the patients with chronic hemiparetic stroke, it would be more efficient ways for us to consider all the effects of sensory organs with more than one clinical evaluation method.

The proportion of people who contacted pulmonary T.B. in Korea has drastically decreased as a result of the incessant effort of the Korean government which adopted a policy of“drive out T.B.”as its foremost health policy. However, the proportion still remains relatively high com-pared with that of developed countries. This study attempts to find some means for guiding and educating college students who have T.B. in their health care by (1) first determining the effect if their self-concept and health beliefs on their behavior in regard to their disease and (2) then predicting the level of compliance of the new patients to the treatment suggested by the health specialist, before the commencement of the treatment. The subjects of this study consisted of 88 mald and female students at Y University who were diagnosed as minimal pulmonary T.B. patients and registered at the health clinic of Y University during the period between September 1, 1981 and March 31, 1953. Data were collected from them by means of questionnaire and interview. The instruments used for this study were (1) a part of Junghoon Choi's“Perceptual Orientation ,Scale”for measuring self-perception of patients and (2) Rosenberg's questionnaire for measuring patients' evaluation of self-esteem, and (3) an instrument for measuring patients' health beliefs which was developed by this researcher utilizing information available from references. The collected data were analyzed using descriptive statistics, chisquare test, Pearson correlation coefficient and t-test. The findings were as follows: 3. Test of hypotheses 1) Hypothesis 1: Patients with high self-concept will be high in health beliefs. For testing this hypothesis a calculation of Pearson correlation coefficient (r) between the patients' self-concept and their health beliefs was carried out. The result of this test was -. 0756 which was not significant at α=.05 and hence hypothesis 1 was not supported. 2) Hypothesis 2: Patients with a high self-concept will tend to be high in compliance with the suggested treatment. Again a Pearson correlaton coefficient was calculated between the two variaibles in the hypothesis. The calculated coefficient r was .1558 which was not significant at α=.05. Hence hypothesis 2 was rejected. 3) Hypothesis 3: Patients with high susceptibility will have a high compliance level. The correlation coefficient between the two variables was -.1975, which was significant at α=.05 but due to the negative sign hypothesis 3 could not be accepted. 4) Hypothesis 4: Patients who take their disease seriously will have a higher compliance level. The calculated correlation coefficient between the variables in this hypothesis was .1642 which was not significant at α=.05 and hence hypothesis 4 was rejected. 5) Hypothesis 5: Patients with a high sense of the benefit of treatment will have a high level of compliance. The computed correlation coefficient was .3129 which was significant at α=.05 and hence hypothesis 5 was acepted. 2. Findings from the correlation analysis were as follows: 1) Patients' susceptibility and their compliance to treatment was negatively correlated (r= -. 1975) which was significant at α= .05. This implies that as the patients' level of susceptibility increases their compliance level decreases. 2) Patients' susceptibility and their self-concept were negatively correlated (r= -. 1790) which was again singnificant at α=.05. The implication of this is that as the patients’self concept increases their susceptibility to disease decreases. 3) Patients' self-concept and their sense of benefit derieved from the treatment was positively correlated (r=.1970) which was significant at α=.05. That is, patients with a high self-concept perceived a great sense of benefit from the treatment. To summarize, patients who are low in susceptibility have a high level of compliance and self-concept.

This study investigates quantitative methods for assessment of infrared analysis of concrete admixtures using correlation coefficients by performing IR scans following the ASTM C494/C494M-11 specifications. In order to achieve this goal, numerous IR scans were performed on specimens supplied by the manufacturer from different batches to ensure uniformity and equivalency. These scans were then analyzed to create correlation coefficients for each admixture. The correlation coefficients were used to quantitatively evaluate and interpret IR Scans of job samples. The study focused on 23 most commonly used concrete admixtures by the New Jersey Department of Transportation (NJDOT). They include air-entrainers, accelerators, retarders, water reducers, and other combinations of these admixtures. Their correlation coefficients were established by analyzing a total of 12 scans of each admixture from three different batches supplied by the manufacturer at different time intervals. In order to validate the obtained correlation coefficients and establish a target correlation, job samples were tested and compared to the obtained correlations. The study also evaluated the effects of drying time and using different types of KBr on correlation coefficients.

The purpose of this study was to examine the relationship between subjective and objective evaluation in speakers with voice disorders. Subjective evaluation indicates the self-reports of voice problems by dysphonic speakers. The relating protocol is the Voice Handicap Index (VHI) and the self-awareness index of voice problems (SAIVP-14). A total of 48 individuals with voice disorders replied to the questionnaire and participated in a voice assessment. Objective evaluations included the perceptual judgement of G grade in GRBAS, acoustic measurements (jitter, shimmer, NHR) by MDVP (CSL 4400), and aerodynamic measurements (MPT, MFR, psub) by PAS (Phonatory Aerodynamic System, KayPentax, USA). Pearson and Spearman correlations were used for the analysis. In the correlation with perceptual judgement (G grade) and VHI-Total, VHI-Physical, and SAIVP-14, there was a significant correlation, but the overall correlation was poor. NHR, jitter, and shimmer were significantly correlated with overall VHI and SAIVP-14. Specifically, the correlation with shimmer was stronger compared to the other measurements. In aerodynamic measures, MFR and MPT showed a significant correlation with VHI-Total, VHI-Emotional, and SAIVP-14, but their correlation was poor. The results of this study suggested that subjective evaluation of self voice problems is meaningfully correlated with objective evaluations, but more data in the multidimensional voice assessment should be collected and analyzed for the reliability and validity of the voice handicap questionnaire.

The purpose of this study is to identify the level of polypharmacy use, drug knowledge, and drug misuse behavior in the elderly, and to understand the correlation between them and their effect on drug misuse behavior. The study design was a descriptive survey study, and the participants of the study were 215 elderly people from the local community center. The research tool used drug knowledge, drug misuse behavior, and the data collection period was from February 8 to 19, 2021. The data analysis were descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficient, and regression analysis. As a result of the study, a significant correlation variable for the drug knowledge of the elderly showed a significant correlation with prescription and non-prescription, r=.145 (p<0.05), and r=.-. 136, which showed a negative significant correlation (p<0.05). As for the significant correlation variable in the drug misuse behavior of the elderly, when prescription and non-prescription were combined, there was a significant correlation with r=.256 (p<0.01), and when not using drugs, r=.-.225 was negative. showed a significant correlation (p<0.01). In terms of the effect on drug misuse behavior, chronic disease =.145, prescription and non-prescription use = .233, which had a positive effect, and non-prescription = -.328, indicating a negative and significant effect. The provision of education on the safe use of drugs by the elderly should first be provided in the community. In addition, we need systematic education and social support for the transmission of correct knowledge on multi-drug use by the elderly and for health management.

In 2011, an earthquake and subsequent tsunami hit the Fukushima Daiichi Nuclear Power Plant, causing simultaneous accidents in several reactors. This accident shows us that if there are several reactors on site, the seismic risk to multiple units is important to consider, in addition to that to single units in isolation. When a seismic event occurs, a seismic-failure correlation exists between the nuclear power plant's structures, systems, and components (SSCs) due to their seismic-response and seismic-capacity correlations. Therefore, it is necessary to evaluate the multi-unit seismic risk by considering the SSCs' seismic-failure-correlation effect. In this study, a methodology is proposed to obtain the seismic-response-correlation coefficient between SSCs to calculate the risk to multi-unit facilities. This coefficient is calculated from a probabilistic multi-unit seismic-response analysis. The seismic-response and seismic-failure-correlation coefficients of the emergency diesel generators installed within the units are successfully derived via the proposed method. In addition, the distribution of the seismic-response-correlation coefficient was observed as a function of the distance between SSCs of various dynamic characteristics. It is demonstrated that the proposed methodology can reasonably derive the seismic-response-correlation coefficient between SSCs, which is the input data for multi-unit seismic probabilistic safety assessment.

The spectrum and the number of the values of the cross-correlation function between the maximal period binary sequences have been extensively studied because of their importance in communications applications. In this paper, we propose the new family of the sequences using the decimation $d=2^{m-1}(3{\cdot}2^{m}-1)$. And we find the spectrum of the cross-correlation function of the sequences and analyze the number of times each value occurs for $0{\leq}{\tau}{\leq}2^{n}-2$.

Purpose: This study was conducted in order to understand the correlation between professionalism, job satisfaction, and job performance of physical therapists Methods: Subjects included 148 physiotherapists. We conducted a questionnaire survey on professionalism, job satisfaction, and business performance. We then performed a correlation analysis. Results: The highest 'compliance of professional organization' in professionalism, the lowest 'vocation awareness of the profession'. In job satisfaction, the highest satisfaction was reported for 'supervisor', and the lowest satisfaction for 'duty'. Professionalism and job satisfaction/job satisfaction and job performance showed a clear positive correlation, and professionalism and job performance showed a weak positive correlation. Conclusion: The results of this study indicate that, in order to improve the job performance of the physical therapist, it is necessary to improve professionalism and job satisfaction. Physical therapists should improve their professionalism in order to improve job performance. In addition, research to improve job satisfaction and job performance of the physical therapist should be continued.
