As of late, air quality information has been actively gathered and investigated in order to find possible environmental risk factors that may affect the onset of cardiovascular disease. Nevertheless, existing studies are limited in the detailed analysis because they take advantage of the air quality information of the macro statistics divided into administrative districts. This paper proposes the construction of distance-based air quality dataset using a domestic hospital’s geographical location information as a reliable data gathering step for a more detailed analysis of environmental risk factors. For the construction of the dataset, air quality information was obtained by utilizing the geographical location of a hospital—in which a patient with cardiovascular disease had been admitted—and then matching the hospital with a meteorological and air pollution station in its vicinity. An air quality acquisition system based on GMap.net was devised for the purpose of data gathering and visualization. The reliability of the experiment was confirmed by evaluating the matching rate and error of air quality values between the acquired dataset with existing area-based air quality datasets from matched distances. Therefore, this dataset, which considers geographical information, can be utilized in multidisciplinary research for the discovery of environmental risk factors that can affect not only cardiovascular diseases but also potentially other epidemic diseases.

The purpose of this study was to investigate the impact of a teacher's leadership (initiating and consideration), class climate, and friendship on academic attitudes. In order to accomplish this, 1,533 elementary school students were recruited. Descriptive statistics and path analysis were employed to examine relationships. The major findings of this study are as follows. First, there were positive correlations between academic attitudes and the teacher's leadership, class climate, and friendship. Second, results of path analysis illustrated that a teacher's leadership consideration indicator had a direct impact on class climate, friendship, and academic attitudes. Furthermore, the teacher's leadership consideration indirectly affected academic attitudes through mediation of class climate and friendship. However, the teacher's leadership initiating indicator did not have a direct impact on class climate, friendship, and academic attitude. The indices of the best fit model for these variables were adequate (GFI, NFI, CFI > 0.90). This study shows that the teacher's leadership consideration is the significant predictor for elementary school students' class climate, friendship, and academic attitudes. Finally, the meaning and limitations of this research, and its implications on academic assistance and intervention, are discussed in detail.

The purpose of this study was try to check the change of a subjective evaluation about the life function fitness and health-related quality of life by executing the home support exercise program three times a week for total 16 weeks with elderly women that are order than 70 years old. The experiment group(total : 17 people, mean age : 79.4) and the control group(total : 17 people, mean age : 80.7) live Yeonje-gu in Busan city, and they don't have any physical injury and any inconvenience to move. and they are all composed of elderly women who agree to participate in this study. We carried out an analysis of covariance with SAS 9.2 statistics package. These are the results from it. First, the experiment group showed statistically significant increase(p<.001) in lifting dumbbells, repeatedly standing up and sitting down, 2.24m shuttle running, walking at the same place for 2 minutes. Second, there was no particular effect with the experiment group in flexibility(catching hands with their backs leaned against each other). This result point out that there is a need of supplementation like adding exercise item which can improve flexibility to home support exercise program. Third, there was no particular difference between the experiment group and the control group in 8 sub-factors with the subjective evaluation about health-related quality of life through SF-36. However, there the bodily pain and vitality sub-factors of experiment group was better than that of the control group with p<.10 level, so we considered this result showed us the positive effect slightly.

Interval mapping using microsatellite markers was employed to detect quantitative trait loci (QTL) in the experimental cross between Berkshire and Yorkshire pigs. In order to derive critical values (CV) for test statistics for declaring significance of QTL, permutation test (PT) of Churchill and Doerge method(1994) and the analytical method(LK) of Lander and Kruglyak(1995) were used by each trait and chromosome. 525 $F_2$ progeny phenotypes of five traits(carcass weight, loin eye area, marbling score, cholesterol content, last back fat thickness) and genotypes of 125 markers covering the genome were used. Data were analyzed by line cross regression interval mapping with an F-test every by 1cM. PT CV were based on 10,000 permutations. CV at genome-wise test were 10.5 for LK and ranged from 8.1 to 8.3 for PT, depending on the trait. CV, differed substantially between methods, led to different numbers of quantitative trait loci (QTL) to be detected. PT results in the least stringent CV compared at the same % level.

Background: An appropriate use of hospital beds can improve productivity of hospital significantly. The authors' previous study revealed that approximately one third of Korean hospital bed days and one sixth of admissions were inappropriately used, when it was measured by Appropriateness Evaluation Protocol(AEP) and Delay Tool modified into Korean situation by the authors. This study aims to evaluate applicability of the instruments in a new hospital. More specifically the study aims to measure appropriateness of the instruments used by newly trained nurse reviewers at a new hospital setting. Methods: In order to evaluate applicability of these instruments, agreement rates of the scores recorded by newly trained nurse reviewers with by skilled nurse reviewer and also compared with the scores recorded by physician's implicit decision were assessed. Agreement rates were derived from concurrent application of AEP and Delay Tool to 52 admissions and 104 patient days from internal medicine, pediatrics, and general surgery of one university hospital. Overall agreement rate, specific nonacute agreement rate, and kappa statistics were used to indicate level of agreement. Results: Overall agreement rates on appropriateness between newly trained nurse reviewers and skilled nurse reviewer were 100% in admission and 98% in bed days. Overall agreement rates on reason for inappropriateness between newly trained nurse reviewers and skilled nurse reviewer were 96% in admission and 91% in bed days. Overall agreement rates between newly trained nurse reviewers and physician reviewer were 86% in admission and 87% in bed days. Conclusion: Results indicated that AEP and Delay Tool were applicable to a new hospital in detecting inappropriate utilization of beds and reasoning of the inappropriateness. These instruments could contribute to enhance efficiency of hospital use, through continuous monitoring of level of inappropriate hospital use at national or individual hospital level.

The purpose of this study was to investigate the mediating effects of parental attachment and ego resiliency in the tendency toward social networking site (SNS) addiction in college students. For this purpose, 382 college students in the Jeju area were surveyed and their responses analyzed. To analyze the collected data, structural equations were implemented using SPSS Statistics version 18.0. According to the results of the study, there is a significant negative correlation between attachment formation and SNS intoxication in college students, and a negative correlation between ego resiliency and SNS addiction. Also, there is a significant positive correlation between formation of parental attachment and ego resiliency in college students, indicating that parental attachment and ego resiliency are significant factors in lowering SNS addiction. Second, in order to examine the mediating effects of ego resiliency in the relationship between the formation of parental attachment and SNS addiction in college students, a research model and a competition model were established and verified. As a result, the relationship between parent attachment and SNS addiction was mediated completely, and the research model is more appropriate. These findings suggest that ego resiliency is of practical significance in seeking ways to improve the problem of SNS addiction in the future. In other words, overuse of SNSs by university students can lead to addiction, but strengthening ego resiliency enables sound SNS use.

The purpose of this study was to examine the mediating effects of experiential avoidance on the relationships between life stress, depression and smartphone addiction in nursing college students. This study was conducted using a descriptive survey design. Participants were 283 nursing college students attending freshmen and sophomore yearsat one university in Jeollanam-do. Data were collected from September 1 to 15, 2015 using self-report questionnaires. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, hierarchical regression and Sobel test with SPSS 21.0. There were significant positive correlations between life stress, depression, smartphone addiction and experiential avoidance. Experiential avoidance partially mediated the relationship between life stress and depression of nursing students. Additionally, experiential avoidance partially mediated the relationship between their life stress and smartphone addiction. The results show that experiential avoidance plays a key role in psychopathology and grows with depression and smartphone addiction. Based on the present findings, nursing interventions should be developed to decrease experiential avoidance, with additional consideration towards the relationship between life stress and experiential avoidance, in order to prevent depression and smartphone addiction among nursing college students.
