Background: Communication is important for the elderly to maintain existing social relationships while creating new relationships based on good communication skills to lessen psychological and emotional distress and lead a healthy life in advanced age. Aims: This study identifies the difference between the social network-based quality of communication life and the overall quality of life in the elderly and how much the quality of communication life affects the overall quality of life. Methods: This research includes a survey of the elderly aged 65 and over living in small cities of South Korea. Data sets of 201 elderly were analyzed. Results: This study found a significant correlation between the quality of communication life and the overall quality of life. Religion also influences the elderly's quality of communication life. The elderly's quality of communication life has 40% explanatory power of the overall quality of life. Conclusion: Consequently, senior citizens' quality of life will be improved through the enhanced quality of communication in addition to financial and health conditions by participating in various community activities similar to those provided by religion to increase opportunities for communication.

This research aims to examine the relationships between empathy and attitudes toward curricula integration of engineering students. To achieve this goal, first, differences in empathy and attitudes toward curricula integration among engineering students were examined. Second, the effects of attitudes toward curricula integration, as perceived by engineering undergraduate students, on empathy were explored. A total of three hundred and two engineering undergraduate students from three universities in Korea responded to survey based on a two-variables scale. The findings were that, firstly, a positive correlation among sub-factors of empathy and attitudes toward curricula integration was identified. Secondly, attitudes toward curricula integration could explain about 12% of empathy. The practical implications of these findings are discussed herein, with particular attention on education for promotion of empathy for engineering students.

The concentrations of $SO_2$ and $SO_3$ were measured to estimate a new developed long time exposure $SO_2$ sampler at Onsan industrial area considering the meteorological factors from June to October, 1992. The mean concentration of $SO_3$ by $PbO_2$ method was 0.924 mg $SO_3 / 10cm^2$ $PbO_2$/day and their high values were shown in the center of the industrial area, which show potential pollution due to the increase of industrial activities and micrometeorological factors in and around the sites. As a result of statistical correlation between $SO_2$ concentration by new sampling method and $SO_3$ concentration by $PbO_2$ method in July and August, 1992, correlation coefficients were high (r=0.87, 0.91) and shown more than 0.83 value in the high concentration data set, which was arbitrarily divided into 7~10${\mu}l$$SO_2$ concentration in an attempt to further investigate these relationships. Therefore, use of new developed long time exposure TEX>$SO_2$ sampler is good for TEX>$SO_2$ measurement and valuable for estimation of air quality in the urban and industrial area. Key Words : a new developed long time exposure TEX>$SO_2$ sampler, correlation coefficients, high, $SO_2$ measurement, estimation of air Quality.

The purpose of this study was to analyze the effects of children's self-esteem on their school adjustment, focusing on the mediation of peer attachment. A total of 2,200 3rd grade children from the third Korea Child-Adolescent Panel Survey participated in this study. The instruments used in this study were the Self-esteem Scale, Peer Attachment Scale, and School Adjustment Scale. The collected data were analyzed by using a Student's t -test, Pearson's partial correlation, simple regression, and hierarchical multiple regression with SPSS ver. 16.0 software. The main results of this study are as follows: first, the boys had higher self-esteem, peer attachment, and school adjustment scores than the girls. Second, there was a significant positive correlation between children's self-esteem and peer attachment as well as a significant positive correlation between children's self-esteem and school adjustment. Further, there was a significant positive correlation between children's peer attachment and school adjustment. Finally, children's self-esteem exerted positive effects on their peer attachment, and children's peer attachment had a positive influence on their school adjustment. The effect of children's self-esteem on their school adjustment was partially mediated by their peer attachment. These findings provide preliminary evidence that the relationships between children's self-esteem and school adjustment may be mediated by their peer attachment.

Purpose: The purpose of this study was to investigate the difference and correlation of interpersonal relationship and purpose-in-life in health allied college students depending on their ability to manage anger. Method: A total of 244 students were surveyed using structured questionnaires. Data were analyzed using descriptive statistics, t-test, and Pearson Correlation Coefficient with the SPSS program. Results: No significant difference of interpersonal relationship was observed between the anger controlled group and the anger uncontrolled group. Intimacy (p=.008) and understanding (p=.017) were significantly higher and openness was significantly lower in the anger controlled group (p=.024). Purpose-in-life was significantly higher in the anger controlled group (p<.001). There was no significant correlation of anger management and interpersonal relationship, however, there was significant positive correlation of anger management and purpose-in-life (r=0.15, p=.017) and interpersonal relationship and purpose-in-life (r=0.29, p<.001). Conclusion: An education program for freshmen who cannot control anger can promote interpersonal relationship and purpose-in-life.

To well design the solar energy system using solar energy, the correlation to calculate solar irradiation is basically needed. So, this study was performed to reveal the relationships between the solar irradiation and four meteorological observation data(dry bulb temperature, relative humidity, sunshine duration, and cloud cover) which are different from previous other researches. And then, we finally proposed the first order non-linear correlation from the measured solar irradiation using four meteorological observation data with MINITAB. To show the deviation of the solar irradiation between measured and calculated, this study compared using the daily total solar irradiance and the maximum peak value. From those results, the calculation error was estimated about maximum 25.4% for the daily total solar irradiance. The error of the solar irradiation between measured and calculated was made from the curve fitting error. So, solar irradiation prediction correlation with higher accuracy can be obtained using 2nd or higher order terms with four meteorological observation data.

Purpose: The purpose of this study was to develop and evaluate a Korean questionnaire to measure resilience in children with chronic illness. Methods: Item construction was drawn from an extensive review of the literature, existing questionnaires and interviews with parents. Content validity was tested by experts. To further refine the questionnaire and test its reliability and validity, data were collected from the 202 children with asthma, diabetes mellitus or nephrotic syndrome. Corrected items were used to total correlation coefficient and test-retest reliability. Questionnaire testing was conducted using factor analysis, Cronbach's $\alpha$, and correlation coefficients. Validity of the questionnaire was tested using internal consistency, construct validity, and criterion-related validity. Results: Components of the questionnaire were in three domains; interpersonal characteristics, characteristics of coping, and intrapersonal characteristics. Factor analysis is showed five factors; positive self-understanding, self-reliance, resourcefulness, perception of positive family relationships, and intimacy. The questionnaire showed a high internal consistency. A significant positive correlation with the Numerical Rating Score and negative correlation with the Child Depression Inventory support the validity of the questionnaire. Conclusion: This instrument demonstrated high reliability and validity. Therefore, this instrument can contribute to the evaluation of resilience of chronically ill children and to any subsequent intervention as well as to develop a theory for resilience.

Purpose: This study was to identify the relationship between family support, self-efficacy and self-care performance in patients with chronic illness. Methods: The subjects were 100 in-and out-patients who were diagnosed with chronic illness at university hospital in Cheonan. The data analyzed using descriptive statistics, Pearson correlation coefficient and stepwise multiple regression with SPSS WIN 12.0. Results: The level of family support, self-efficacy and self-care performance were high. The family support in patients with chronic illness indicated a significant positive correlation to self-care performance but no significant correlation to self-efficacy. The self-efficacy in patients with chronic illness indicated a significant positive correlation to self-care performance. Family support and self-efficacy account for 24.4% of variance of the self-care performance. The most significant predictor which influenced self-care performance in patients with chronic illness was family support. Conclusion: The results of this study showed that family support and self-efficacy are very important variables in explaining the self-care performance. Therefore, these variables should be considered in nursing intervention development and education.

In this paper, we propose a method of significant term extraction within a document. The technique used is Principal Component Analysis(PCA) which is one of the multivariate analysis methods. PCA can sufficiently use term-term relationships within a document by term-term correlations. We use a correlation matrix instead of a covariance matrix between terms for performing PCA. We also try to find out thresholds of both the number of components to be selected and correlation coefficients between selected components and terms. The experimental results on 283 Korean newspaper articles show that the condition of the first six components with correlation coefficients of |0.4| is the best for extracting sentence based on the significant selected terms.
