Pollutant Gases

Big data mining and pollution are extremely important issues in todays. An innovative method in this study was used for visually discovering the relationship between pollutant gases by MapReduce. One dimensional, two-dimensional, and three-dimensional visualization used to visualize the data, that was processed as an hourly reading for one year from an air quality monitoring station to study the behaviors of pollutant gases distribution, and to show graphically the distribution of one, two, or three gases. The number of readings used in this paper are 8760 hourly readings for each of the five pollutant gases under this study. Pearson correlation used to explore numerically the correlation between the pollutant gases, and eta factor used to evaluate the effect of one gas on the other pollutant gases. We found out by both methods, visually and numerically the same facts that related between the pollutant gasses. The ozone has a moderate negative correlation of value -0.622 with nitrogen dioxide, and weak negative correlation of value -0.248 with carbon monoxide, and -0.155 with carbon dioxide. Ozone has approximately no correlation of value .060 with silver dioxide. The carbon monoxide has moderate positive correlation of value 0.364 with carbon dioxide. The eta factor between ozone and nitrogen dioxide is very weak of values 0.292, and 0.009 with Sulphur dioxide, this proved an important fact that the ozone, nitrogen dioxide, and Sulphur dioxide sources are different. The study recommends that each country must analysis visually and numerical the big data that was collected yearly from the monitoring stations to control the pollution gases especially near the large industrial factories.

This study aims to determine the relationship between perception of parent’s interpersonal communication ability with juvenile delinquency tendency. The hypothesis of this study is the perception of parent’s interpersonal communication ability have a negative correlation with juvenile delinquency tendency. Participants consisted of 100 male and female middle adolescent who studied in several senior high school in Yogyakarta. The Perception of Parent’s Interpersonal Communication Ability Scale (18 item) and The Tendency of Juvenile Delinquency Scale (25 item) were used in this study. Data were analyzed using Product Moment Pearson Correlation method with SPSS version 21. The result showed that the perception of parent’s interpersonal communication ability significantly has a negative correlation with juvenile delinquency tendency (r=-0,295, p<0,01).

The Relationship

Obesity is a significant factor in health information and increases the risk of health problems. Hence, an application that can help users to monitor their body mass index (BMI) timelines is needed. The simulation of a personalized 3D body shape may encourage women to control their BMI for a healthy body and pleasant appearance. Therefore, this paper aims to develop computerized 3D models of female shapes for various weights and heights, and consists of three important parts. First, the preparation of six avatars is described. Second, the body proportions of 6767 female datasets are analyzed to find the relationship of variables in various weights and heights. Last, 3D morphing of different female shapes is developed and analyzed experimentally for appropriate morphing parameters. Accuracy tests are carried out in three ways. First, body proportions calculated using the Z-Size Ladies application, called “Z-Size calculations,” are compared with the body proportions of data obtained from 3D scanners. Second, the Z-Size calculations are compared with tape measurements. Last, the Z-Size calculations are compared with measurements of Z-Size 3D morph models. The results of accuracy tests are shown as the relationship graphs between the BMI and body proportion measurements of chest, waist, hip, and inseam. Bland–Altman plots and Pearson correlation calculation show high correlation. In conclusion, the data obtained from the Z-Size calculations, 3D Scanner, tape measurements, and Z-Size morph models’ measurements are in good agreement and are highly correlated. The simulation of 3D female shapes for different weights and heights as proposed shows good performance and high accuracy.

Oxygen Atoms

The addition of ethane to nitrogen dioxide either during exposure to radiation transmitted by pyrex, or afterwards, reduces the amount of oxygen formed. At room temperature this is apparently due to the effectiveness of ethane in promoting the reverse reaction of nitric oxide and oxygen to form nitrogen dioxide. At temperatures over 100° there is a reaction which uses oxygen atoms produced in the primary process. Nitroethane (or nitrosoethane) is formed along with carbon monoxide, carbon dioxide, and some methane. The results suggest that acetaldehyde is an intermediate, but acetaldehyde could not be detected because it would react thermally with nitrogen dioxide. It is not possible to give a complete explanation of the results, but suggestions can be made which might form the basis for later work.

The Relationship

Dissolved gas analysis (DGA) in transformer oil is considered as one of the preferred projects to discover the potential faults of the transformer. To identify the aging characteristics of oil-immersed transformer oil in long-term operations, it is important to study relationship between total hydrocarbon and gases dissolved in transformer oil. This paper used Pearson correlation coefficient to analyze the relationship with the data of DGA. At last, it gives the result that the correlations between the total hydrocarbon and carbon monoxide, methane, ethane, ethylene, acetylene was positive. Therefore, this study lays the foundation which help to diagnose the aging status of transformer.

Abstract Background and objective The incidence of atrioventricular nodal reentrant tachycardia (AVNRT) in elderly patients has increased due to an increased in life expectancy of the general population. Slow pathway (SPs) ablation is considered the treatment of choice for patients with AVNRT. This study is interested in the relationship of the distance from SPs to His bundle electrogram (HBEs) in various age groups because understanding of anatomy clearly could guide treatment patients by using radiofrequency ablation to be easier and safer. Design and methods A cross-sectional study was analyzed in patients diagnosed with AVNRT and underwent SPs ablation using EnSite NavX mapping system guided therapy. The distance from SPs to the lowest HBEs recorded was measured. Relationship between distance from SPs to HBEs and age was analyzed by Pearson correlation. Results A total 68 adults diagnosed with AVNRT (27.9% males, mean age 52.43 years old) were included. The mean distance from SPs to HBEs is shorter in the group older than or equal to 60 years old (n=24, mean age 70.70 years old) compared to the group younger than 60 years old (n=44, mean age 42.45 years old) (13.77 vs. 17.73 millimeter, p=0.024). Average fluoroscopy time was greater in the older group compared to the younger group (24.43 vs. 16.52 minutes, p=0.002) while the procedure time in both groups was not different (105.1 vs. 85.48 minutes, p=0.09). The distance from SPs to HBEs was negative correlation with age with the coefficient of −0.392 (p&lt;0.001). When dividing the age group into three age groups, the group that younger than 40 years old (n=15, mean age 29.73 years old), 40 to 60 years old (n=29, mean age 49.03) and older than 60 years old (n=24, mean 70.70 age), the average distance from SPs to HBEs was 20.77, 16.15 and 13.77 millimeter respectively. The mean distance from SPs to HBEs in the group younger than 40 years old is significant statistically different to the group that is older than 60 years old (p=0.006). Slow pathway ablation was successful in all patients in this study except for one patient who was 72 years old because frequent transient atrioventricular block occurred during ablation. Conclusion Distance from SPs to HBEs was negative correlation with age by measuring with 3-dimentional mapping. Distance from SPs to HBEs in each groups Funding Acknowledgement Type of funding source: None
