  • The purpose of this study were to factor analyze the 25-item Personal Resource Question-naire (PRQ)-Part II, a social support measure, and to establish construct validity for the instrument among adolescents by relationship found between perceived social support and the theoretically relevant variables of attachment, parent-child relationships, and coping, The sample was consisted of 451 college students, aged 18 to 24. According to the criteria used in this study a four-factor structure, which consisted of 15-items, resulting from a principal components analysis with an oblique rotation, best represented the multidimensionality of the PRQ-Part II of late adolescents in Korea. Evidence in support of construct validity for both the 15-item and 25-item PRQPart II was provided by statistically significant correlations found between the two scales and the theoretically relevant variable of attachment, parent-child relationships, and coping. With the findings of this study, the 15-item Korean version of the PRQ-Part II can be used in research and practice as a reliable and valid instrument measuring perceived social support for late adolescents in Korea.

  • The PRQ instrument is parental perspectives of the parent-child relationship. It measured parent-child dimensions that include attachment and involvement. Also, it provides additional information on parenting style, parenting stress and satisfaction with the child's school. This study tested reliability and validity of the Korean version of Parenting Relationship Questionnaire-Child (K-PRQ-C). The K-PRQ-C was administered to parents of 713 elementary school children including 362 boys and 351 girls. They were from 1st to 6th grade children who were recruited form 4 elementary schools in Korea. Reliability was tested through internal consistency. We conducted confirmatory factor analysis. Moreover, scale inter-correlation was conducted for validity test. Discriminant validity conducted through administration to the parents of clinical children with emotional and behavior disorders. Construct validity was also examined through Korean version of the Parenting Sense of Competence. The results of confirmatory factor analysis indicated that the similar factor structures exist for PRQ-C and K-PRQ-C. The results showed a high level of internal consistency as well as construct and discriminant validity. These results showed valid psychometric properties for the K-PRQ-C. The K-PRQ-C provides a reliable and valid means of gathering information about the parent-child relationship. We discussed Implications for the use of the K-PRQ-C as a clinical tool and as a research instrument.

  • International Roughness Index (IRI) has been widely used by state DOTs to quantify pavement smoothness. When pavement condition falls below certain IRI thresholds, corresponding pavement maintenance treatments should be considered for application. Selection of appropriate IRI thresholds is essential to tactical allocation of limited resources to improve the conditions of states' roadway systems. This selection process is often challenging, however, because IRI thresholds are largely determined by Perceived Ride Quality (PRQ), and PRQ differs in each state. In this paper, a framework is proposed to address this problem. Passenger raters will be randomly selected from predetermined geographic locations, and their PRQ ratings collected. Taking this perceived ride data, along with other data collected, a statistical analysis will be conducted to establish the relationship between measured IRI values and PRQ. Appropriate IRI thresholds will then be determined. Once this framework is implemented, state DOTs could make informative maintenance decisions, which are expected to greatly enhance the public perception of pavement conditions in today's challenging economy.

  • Background: Pneumoconiosis, like other chronic respiratory diseases, is essentially incurable and, for many, progressive. While improved survival time is an important aim of treatment, there is growing recognition that for some people, improving the quality of life is more important than extending the length of life. Currently the measurement of the quality of life is used to assess the efficacy of therapeutic agents. Methods: Sixty-three pnemoconiotics who were admitted to St. Mary's Hospital between April and August 1999 were interviewed using COOP charts, Chronic Respiratory Questionnaire(CRQ) and Pneumoconiotic Respiratory Questionnaire(PRQ), a newly developed questionnaire concerning clinical and socioeconomic features of pneumoconiotics. Also, ILO classification of the chest film, pulmonary function test, and arterial blood gas analysis of the patients were evaluated. The scores between Industrial Accident Compensation Insurance(IACI) covered and uncovered patients and between clinically stable and unstable patients were compared. Results: Domains of CRQ and PRQ showed a high internal consistency reliability($\alpha$=0.86-0.89, 0.77-0.81) except the dyspnea domain($\alpha$=0.63) of CRQ. The scores on the CRQ and PRQ showed statistically significant correlations with the results of COOP charts, pulmonary function test and arterial blood gas analysis. The dyspnea domain and social activity domain of the PRQ showed significant difference between IACI covered and uncovered patients and between clinically stable and unstable patients. Conclusion : Korean translation of the Chronic Respiratory Questionnaire and the newly developed Pneumoconiotic Respiratory Questionnaire are reliable and valid methods and are likely to be useful in measuring the quality of life in patients with the chronic respiratory disease including pneumoconiosis.

  • Objective: This study ascertained effects of roughage quality, period of day at meal termination and time lapse after feeding on digesta load in the rumen. Methods: Veld hay was untreated (poor roughage quality, PRQ), improved (improved roughage quality, IRQ) by treating with urea or semi-improved by spraying with urea (semi-improved roughage quality, SIRQ). Experiment 1a used four rumen fistulated sheep to determine in-sacco degradability. Twelve sheep ($56.3{\pm}4.59kg$) were blocked by weight and randomly allocated to IRQ (n = 6) and PRQ (n = 6) to determine solid and liquid passage rates. In experiment 1b, nine sheep ($37.6{\pm}9.34kg$) were blocked by weight and randomly allocated to IRQ (n = 4) and PRQ (n = 5) to determine digestibility. Sixteen sheep ($36.47{\pm}9.46kg$) were blocked by body weight and randomly allocated to IRQ (n = 8) and PRQ (n = 8). Two sheep were slaughtered for each sampling time in each treatment (IRQ and PRQ) at 0, 6, 12, and 24 h after feeding to determine rumen load. In experiment 2, eighteen goats ($25.4{\pm}9.08kg$) were blocked by weight and randomly allocated to IRQ (n = 6), SIRQ (n = 6), and PRQ (n = 6). Then all 18 goats were slaughtered soon after meal termination in the morning; afternoon and evening to determine the effect of period of day on rumen fill. Results: Rate of degradation and effective degradability were enhanced by improvement of roughage quality. Roughage quality had no effect on digestibility, but digestibility was higher in goats than sheep. Fractional passage rate of particles was higher for IRQ than PRQ, but similar for liquids. Digesta fractional clearance rates at 24 h after feeding were 0.018/h (IRQ) and 0.006/h (PRQ). Period of day had an influence on rumen load. Neutral detergent fibre load for goats were above 2.03 kg/100 kg body weight for all diet treatments. Conclusion: Following starvation, passage rate had negligible effects on emptying of rumen load.

  • The purpose of the study was to determine the convergent validity, discriminant validity and internal consistancy reliability of the social support and family support measuring tool. Two procedures were used : 1) Campbell and Fiske's multitrait-multimethod approach and item total correlation with Chronbach's $\alpha$. The result suggest that SNM, NSSQ, SNM/family, NSSQ/famliy is a valid and a reliable instrument for measuring social support. But PRQ part2 is low in convergent validity. The results further suggest that we have to more attention to a valid and reliable likert type scale for social support.

  • Purpose: As a result of dramatic advances in the medical and surgical management of congenital heart disease (CHD), many babies born with cardiac anomalies today can expect to reach adulthood. The main purpose of this study was to examine the relationship between parenting stress and personal resources of mothers of children with CHD. Method: Fifty-one mothers of children with CHD were recruited at the pediatric cardiac outpatient clinic from July 14th to September 25th 2006. Abidin's parenting stress index/short form (PSI/SF) and Brandt and Weinert's personal resource questionnaire (PRQ) were used. PSI has 3 sub-concepts; parental role distress, dysfunctional parent-child interaction, and difficult child. PRQ has 4 sub-concepts; intimacy, social integration, worth, and assistance. Data were analyzed using SPSS 13.0 version. Results: Correlation analysis showed that parenting stress was significantly related to 'intimacy', 'social integration', and 'worth' of mothers. Multiple regression analysis showed that parenting stress was significantly related to personal resource of mother and information by internet. Conclusion: Mothers who felt they had supportive friends and family, high self esteem, and social integration reported lower parenting stress. Also, internet may be an effective method to provide information and share experience for mothers of children with CHD.

  • The purpose of the study was to identify the degree of social support and burden in mothers of children with cancer, and to determine a strategy of an effective social support utility for burden relief in these mothers. The subjects of this study were consisted of mothers of cancer children, registered at a'C'University affiliated hospital in Taejon. The data was collected from July 1 to August 31, 1994. Three instruments were used to collect the data : a semi-structured interview questionnaire which was developed by the researcher was used to identify the content of the mother's burden, a Visual Analogue Scale(VAS) that had a 10cm horizontal line was used to measure the degree of mother's burden and the PRQ part I & part Ⅱ were used to measure the degree of mother's social support. The content of mother's burden collected through in depth interviews was analyzed using content analysis. Also burden and social support data were analyzed by SAS program. The result of this study were summarized as follows : 1. The data on burden content from the interview were categorized as psychological, physiological, family interaction with maternal role, financial burden and personal interaction with social relational burden. 2. The degree of burden measured by VAS had a mean of 8.04(range from 0.5 to 10). 3. The score for social support measured by PRQ part Ⅱ had a mean of 88.9(range from 71 to 113). The highest scores was for reassurance of worth. The lowest score was for opportunity for nuturance. Most of the 15 mothers received the greatest amount of support from their sisters, spouse, friends, neighbors, relations, priest were perceived as eaningful resource person. 4. The correlation coefficient of burden and social support was somewhat negative correlation but no statistical significance(r=-.072). Therefore, a further study is necessary to repeat the qualitative research for exploring factor to be affected family caregiver's burden according to disease proceeding stage. On the basis of the results from this study, future research will be promoted valid and reliable tool development. Through this study, nurses understand and assess the individual psychologic burden and further it would be recommendated to produce professional education program for pediatric oncologic specialist nurse.

  • Objectives : There have been several evidences that the central nervous system defect is one of the etiologic factors in schizophrenia and high nailfold plexus visibility can reflect these defects indirectly. These are particularly related to the negative symptoms of schizophrenia. In this study, we examined the relationship between nailfold plexus visibility and various clinical variables in schizophrenia. Methods : Forty patients(20 males, 20 females) satisfying the DSM-lV criteria for schizophrenia and forty normal controls(20 males, 20 females) were measured for Plexus Visualization Score (PVS) by using capillary microscopic examination. We used Positive and Negative Syndrome Scale(PANSS), Ulmann-Giovannoni Process-Reactive Questi-onnaire(PRQ), Phillips Premorbid Adjustment Scale(PAS), Continuous Performance Test, and Backward Masking for psychopathology and clinical variables. Results : There was no significant relationship between schizophrenic subjects and normal controls in PVS. PVS was correlated with PANSS positively except negative symptom subscore. PVS was correlated with PRQ score negatively, and with PAS score positively. Conclusions : This study shows high PVS are associated with more severe psychotic symptoms and with clinical variables, such as disease process and premorbid adjustment, in some schizophrenics.
