  • This study describes a reasonable planning method for water meter replacement which can minimize the metering under-registration for an increasement of revenue water. The increment analysis of real water usage was used to establish a replacement plan. The meter replacement database collected from K City was used as the basis of this analysis. The database included 964 connections of domestic and non-domestic consumers that had their meter replaced by aging at 2011. The result showed that the corelation between unregistered water volume and water meter age was lower than commonly expected where the current criteria of replacement is only water meter age(8 years) excluding the meters older than 13 years. And in the analysis result of water usage for 8 years, the total amount and increment of water usage had a significant effect on unregistered water volume. However the relation was different tendency as a total volume and slope of increment. In case of total water volume was larger than 10,000, larger than 7,000 and increment of 0.0 ~ -0.3, larger than 6,000 and increment more than -0.3 were analysed to need a replacement because of metering under-registration.

  • Through the low orbit GPS satellite for a 3-dimensional real time position detechtion can be achieved anywhere. Utilizing the GPS sate llite detection values an analysis of the varing characteristics of the ionosphere can be achieved, and by calculating the correlation relationship of the position detection error and the ionospheric time delay characteristics, an advanced algorithm technique can be developed. Computer simulation of the developed algorithm for defining the corelation between the position detection error and the varing ionospheric time delay charcteristics has been proceeded. The results of simulation reveal the fact that the varing characteristics of the ionosphere nearly match the actual ionospheric time delay characteristics.

  • Purpose : This study aims to examine the correlation between SPQ (sasang personality questionnaire) results and the significance level of general mental and physical health among youths. Effects of physical factors on the level of health are also examined. Methods : For the purpose of this study, the SPQ test and body mass and the Ponderal index were measured. The SPQ was followed by a survey on physical changes among 686 young people. The correlation between SPQ and BMI was analysed using Pearson's corelation. Post hoc tests were conducted on SPQ sub factors (SPQ-B, SPQ-C, and SPQ-E) were examined. Results : The findings from the analysis of the high, middle and lower group profiles of adolescent SPQ-B, SPQ-C, and SPQ-E showed that the three groups had significant results. This study demonstrates the correlations among sub factors of the SPQ. No correlation was observed regarding physical characteristics. Conclusion : This study demonstrates the correlations among sub factors of the SPQ. No correlation was observed regarding physical characteristics.
