Objectives: This study was performed to investigate the relationship between regional material deprivation and the standardized mortality ratios(SMRs) of community residents aged 15-64 in Korea. Methods: SMRs were investigated using the registered death data from 1995 to 2000 that was obtained from the Korean National Statistics Office with the denominators being drawn from the 1995 to 2000 census. Material deprivation was measured using the Townsend score that was calculated from the 1995 to 2000 census. The relationship between the regional material deprivation and the SMRs of the community residents aged 15-64 was investigated by using ANOVA, Spearman's rank correlation analysis and Pearson's correlation analysis. The trends in mortality inequality were investigated using the concentration index. Results: On the ANOVA, the SMRs of the men and women residents in the least deprived areas were the smallest and those in the most deprived areas were the largest. Spearman's rank correlation analysis, Pearson's correlation analysis and the concentration index revealed that significant positive relationships exist between the regional material deprivation and the SMRs of the community residents aged 15-64. Conclusions: This study suggests that there are mortality inequalities among the communities in Korea and part of this difference is due to the material deprivation of the community. Strategies aimed at reducing mortality inequalities among the communities will be needed to address economic inequalities. Further studies are needed to explore the mechanisms of how the regional deprivation influences on health and how the other factors of the community influence on the health of the community residents.

This study was conducted to evaluate the factors affecting the quality of life before and after clinical practice for nursing students. The data were collected from 256 nursing students in the third and fourth years at H college and G University through a questionnaire from February 19 to June 29, 2018. The collected data were compiled using the SPSS/WIN 18.0 statistical program with Paired t-test, ANOVA, Spearman rho Correlation, Kendall Correlation, and Multiple Linear Regression. The factors that significantly explained the quality of life of nursing students before and after clinical practice were the reason for application (t=5.268, p<.001), school record (t=4.771, p<.001), depression (t=-4.600, p<.001), monthly income (t=3.383, p=.001), and satisfaction in nursing department (t=3.344, p=.001). The coefficient of determination for these factors, R2, showed an explanation force of 68.5%. These results also inferred that the quality of life of nursing college students is high, with high satisfaction in nursing departments and regular school record and low economic hardship and depression. Therefore, programs should be developed that can improve the quality of life of nursing students before and after clinical practice by continued improvement in the controllable factors of school record and satisfaction in nursing departments and by reducing depression, since the reason for application and the monthly income of nursing students cannot be controlled.

Purpose: To evaluate the correlation between colon transit time (CTT) test value and initial maintenance dose of polyethylene glycol (PEG) 4000 or lactulose. Methods: Of 415 children with chronic functional constipation, 190 were enrolled based on exclusion criteria using the CTT test, defecation diary, and clinical chart. The CTT test was performed with prior disimpaction. The laxative dose for maintenance was determined on the basis of the defecation diary and clinical chart. The Shapiro-Wilk test and Pearson's and Spearman's correlations were used for statistical analysis. Results: The overall group median value and interquartile range of the CTT test was 43.8 (31.8) hours. The average PEG 4000 dose for maintenance in the overall group was $0.68{\pm}0.18g/kg/d$; according to age, the dose was $0.73{\pm}0.16g/kg/d$ (<8 years), $0.53{\pm}0.12g/kg/d$ (8 to <12 years), and $0.36{\pm}0.05g/kg/d$ (12 to 15 years). The dose of lactulose was $1.99{\pm}0.43mL/kg/d$ (<8 years) or $1.26{\pm}0.25mL/kg/d$ (8 to <12 years). There was no significant correlation between CTT test value and initial dose of laxative, irrespective of the subgroup (encopresis, abnormal CTT test subtype) for either laxative. Even in the largest group (overall, n=109, younger than 8 years and on PEG 4000), the correlation was weak (Pearson's correlation coefficient [R]=0.268, p=0.005). Within the abnormal transit group, subgroup (n=73, younger than 8 years and on PEG 4000) correlation was weak (R=0.267, p=0.022). Conclusion: CTT test value cannot predict the initial maintenance dose of PEG 4000 or lactulose with linear correlation.

Objectives: The purpose of this study is to know the correlation of transvaginal sonography findings, CA-125 and blood stasis pattern for 15 adenomyosis patients. Methods: We got questionnaires from 15 patients among 243 patients who had hysterectomy related with adenomyosis in the department of obstetrics and gynecology, OO medical center from April 11th 2010 to November 15th 2010, and analyzed them. We conducted correlation analysis between age, pain(VAS), duration of pain and blood stasis score, and between difference and sum of uterine walls, CA-125 and blood stasis score. For statistics, we used Spearman correlation coefficient and SPSS version 17.0 for windows. Results: The correlation between sum of uterine walls and CA-125 showed statistical significance. The correlation between CA-125 and blood stasis score showed statistical significance. There is no statistically correlation between age, VAS, duration of the pain and blood stasis score. There is no statistically correlation between difference of uterine walls and CA-125, and between difference and sum of uterine walls and blood stasis score. Conclusion: The result showed that sum of uterine walls is related with CA-125. We need a further study to develop blood stasis indicators with a validated questionnaire, and more subjects involved at multiple institutions.

Background: Increasing evidences from experimental studies indicate that apoptosis may be inversely related to angiogenesis in tumor progression. Material and Method: To explore how apoptosis correlates with tumor angiogenesis, we measured the apoptotic index(AI) using the terminal deoxynucleotidyl transferase method(Apop Tag In Situ Apoptosis Detection Kit, ONCOR) and the intratumoral microvessel density using the anti-CD31 monoclonal antibody in non-small cell lung cancer. Result: Statistical analysis revealed an inverse correlation between AIs and intratumoral microvessel densities in squamous cell lung carcinoma(Spearman rank correlation coefficient r=- 0.229, p=0.047). Conclusion: The results of this study demonstrated that the amount of apoptosis in squamous cell lung carcinoma may be influenced by the extent of neovascularization. This suggests that tumor angiogenesis may contribute to a reduction of apoptosis in tumor cells.

This study aims to look at overall adolescents' and college students' perceptions of library and explore the sources and their related variables as well as find out related issues of perceptions of library and information use of them. The data for this study were collected through survey and analyzed descriptive statistics and correlation analysis using the data. The result shows the population users preferred search engine so much over library as their information search tool even if they trust library information sources more, also, they tend to seek information sources when it has easiness and fastness to get. Correlation analysis such as ${\chi}^2$ and Spearman were implemented and the result of the correlation shows that many factors of this study covered-such as comparison of information sources-have significant differences each other.
