본고는 교회의 사회적 책임에 관한 건강한 성장하는 교회들과 건강하지 않은 교회들 간의 관계가 존재하는지 여부를 결정하기 위해 고안되었다. 교회 설문지에는 다음의 사회적 책임에 관한 네 가지 요인들이 포함되었다: 구제 봉사, 개인 개발, 지역사회 개발, 그리고 제도 변화. 건강한 교회 성장과 사회적 책임 사이의 관계에 어떤 중요한 차이도 존재하지 않았다. 교회의 사회사역 점수와 건강한 성장하는 교회인지 여부 사이에 어떤 중대한 차이가 존재하는지를 검증하기 위해 다중 분산 분석 검정이 실시되었다. 또한 요인화된 그룹들과 건강하게 성장하는 교회들과 건강하지 않은 교회들의 사회적 책임에 대한 각 항목 사이에 통계학적 관계들을 평가하기 위해 t검정이 실시되었다. 사회적 책임의 하위영역들이 교회의 건강한 성장을 예측할 수 있는지를 결정하기 위해 로지스틱 회귀 분석이 추가적으로 실시되었다. 사회 사역에 있어서 교회의 참여에 관한 수준과 교회가 건강한 성장하는 교회인지 여부사이에 어떤 차이도 존재하지 않는다는 첫번째 가설이 인정되었다. 사회적 책임의 다양한 하위 영역들과 교회가 건강한 성장하는 교회인지 여부를 예측할 수 있는 상대적 능력사이에 어떤 관계도 존재하는 않는다는 두번째 가설도 인정되었다. 추가적으로, 교회의 사회적 책임의 측면에서 건강한 성장에 관한 정의는 건강한 교회의 정의를 강화했다. 건강한 복음주의적인 교회의 척도에 건강한 사회적으로 책임 있는 교회의 정의를 더한 것은 교회 건강의 더 완성된 정의의 형성을 위해 함께 사용될 수 있을 것이다.

This research was designed to determine whether a relationship exists among healthy growing churches and non-healthy churches regarding the social responsibility of the church. The survey instrument of a church included the survey variables of four factors: relief services, personal development, community development, and systematic change. Significant differences in a relationship between healthy church growth and social responsibility did not exist. Multiple analysis of variance tests were conducted to test whether a significant difference exists between the social ministry score of the church and whether the church is a healthy growing church. Also, t tests were conducted to evaluate statistical relationships between factored groups and between each item of social responsibility in healthy growing churches and non-healthy churches. A logistic regression analysis was additionally conducted to determine whether the subscales of social responsibility would predict healthy growth in a church. The first hypothesis that no difference would exist between the level of a church’s involvement in social ministries and whether the church is a healthy growing church was accepted. The second hypothesis that no relationship would exist between the various subscales of social responsibility and their relative ability to predict whether a church is a healthy growing church was also accepted. Additionally, the definition concerning healthy growth in terms of social responsibility of the church strengthened the definition of a healthy church. The definition of a healthy socially responsible church plus the measure of a healthy evangelistic church could be used together to form a more complete definition of church health.

Purpose: The purpose of this study is to analyze the walking characteristics of jaywalking pedestrians, which account for a large proportion of deaths in pedestrian traffic accidents. Method: As for the analysis method, after collecting data of jaywalking pedestrians using imaging equipment, frequency analysis and statistical verification were performed on the jaywalking characteristics of elderly and non-elderly people. Result: It was found that there was a difference in the characteristics of jaywalking between the elderly and non-elders, but in the case of walking speed, insignificant results were derived. However, it was found that among the elderly, the group having difficulty walking in general had a lower walking speed than the group that did not. Conclusion: It is judged that one of the causes of jaywalking is the perception of illegal activities and insensitivity to the risk of accidents, not the age and walking ability. Therefore, in addition to safety education, it is judged that it is necessary to provide pedestrian safety information that requires the driver's attention in multiple jaywalking sections.

In deciding priorities for waterworks maintenance, a scientific and systematic approach would be needed to examine and analyze the main parameters affecting the leakage, along with water demand quantity, water pressure, energy costs, and so forth. In this study, a statistical analysis was performed to estimate the physical parameters in waterworks maintenance with the highest correlation with the leakage. For this purpose, water distribution analysis was performed to assess the demand energy ratio. The formula of non-revenue water estimation consists of independent variables related with physical parameters for waterworks. Deterioration rate of pipes, demand energy ratio and water supply quantity at each demand point were used in a multiple regression equation for water distribution network analysis. If regional characteristics of distribution network and demand patterns are considered in developed formula, the estimated accuracy for calculating the non-revenue water rate will be improved.

Background: It is very difficult to distinguish between a radioactive contamination source and background radiation from natural radionuclides in the marine environment by means of online monitoring system. The objective of this study was to investigate a statistical process for triggering abnormal level of count rate data measured from our on-line seawater radioactivity monitoring. Materials and Methods: Count rate data sets in time series were collected from 9 monitoring posts. All of the count rate data were measured every 15 minutes from the region of interest (ROI) for 137Cs (Eγ = 661.6 keV) on the gamma-ray energy spectrum. The Shewhart (3σ), CUSUM, and Bayesian S-R control chart methods were evaluated and the comparative analysis of determination methods for count rate data was carried out in terms of the false positive incidence rate. All statistical algorithms were developed using R Programming by the authors. Results and Discussion: The 3σ, CUSUM, and S-R analyses resulted in the average false positive incidence rate of 0.164 ±0.047%, 0.064 ±0.0367%, and 0.030 ±0.018%, respectively. The S-R method has a lower value than that of the 3σ and CUSUM method, because the Bayesian S-R method use the information to evaluate a posterior distribution, even though the CUSUM control chart accumulate information from recent data points. As the result of comparison between net count rate and gross count rate measured in time series all the year at a monitoring post using the 3σ control charts, the two methods resulted in the false positive incidence rate of 0.142% and 0.219%, respectively. Conclusion: Bayesian S-R and CUSUM control charts are better suited for on-line seawater radioactivity monitoring with an count rate data in time series than 3σ control chart. However, it requires a continuous increasing trend to differentiate between a false positive and actual radioactive contamination. For the determination of count rate, the net count method is better than the gross count method because of relatively a small variation in the data points.

In order to identify the environmental factors that cause the dysoxic water, the water temperature difference(del_temp), salinity difference(del_sal), density difference(del_rho), Brunt-Väisälä frequency(bvf), Richardson Number(ri_num) Logistic regression analysis was performed on the six explanatory variables of difference(del_z). Mcfadden R ^ 2 of the regression model was 0.7422 and the explanatory power of the model was good. According to ANOVA analysis, the temperature difference, stratigraphy stability(bvf) and Richardson number were significant in the generation of dysoxic water, and salinity difference was not significant. In particular, the p-value for the temperature difference was 2.2 * 10 ^-16, close to zero. Therefore, it was found that the water temperature difference between the surface layer and the bottom layer is the most influential factor in the occurrence of dysoxic water in Dangdong Bay. As a result of estimating the probability of occurrence of dysoxic water by using the depth difference and water temperature difference among the above six explanatory variables, the probability of occurrence of dysoxic water is 70% when water depths are 5m, 10m, 15m and 20m, The temperature differences were about 8℃, 6℃, 5℃ and 3℃, respectively.

The purpose of this study is to investigate the emotion effects on academic achievement for university students. The results are as follows. Resulting on the each emotions difference by the statistical variables, anxiety scores by gender showed a significant difference in the p<.01 level(F=7.685). The males anxiety(2.478, standard deviation: 0.180) had significantly lower scores than females(3.076, standard deviation: 0.168). But fear, anger, activity, and sociability scores were not significantly different respectively between male and female students. To see the emotions effect of academic achievement, the analysis method of the linear regression line was used. As the result, anxiety, fear, anger, activity, and sociability did not significantly influence academic achievement. And so unlike previous methods, the analysis method of the quadratic regression curve was used. As the result, anxiety, fear, anger, activity, and sociability showed did significantly influence academic achievement respectively within 5% of statistical significance level, to more than F=3.06. Therefore, the values on academic achievement of the each anxiety, fear, anger, activity, and sociability showed a quadratic regression curve. That is, [Academic achievement]=-0.9685×[Anxiety]2+5.1342× [Anxiety]+8.2679,[Academic achievement]= -1.0638×[Fear]2+5.5694×[Fear]+7.5635,[Academic achievement]=-1.3497×[Anger]2+9.1284× [Anger]+0.6720,[Academic achievement]=-1.0589×[Activity]2+7.4386×[Activity]+1.8272,[Academic achievement]=-1.6830× [Sociability]2+11.2325× [Sociability]-3.8258. Therefore, we were able to determine the following conclusions. First, we were able to predict the degree of academic achievement by the each emotions scale. Second, when the each emotion scores of students was a moderate, the academic achievement was most excellent. So, in order for the students to become higher academic achievement, the maintenance of medium degree of the each emotions scores is required.

Critical current of high-temperature superconducting (HTS) coil is influenced by its own self magnetic field. Direction and density distribution of the magnetic field around the coil are fixed after the shape of the coil is decided. If the entire part of the HTS tape has homogeneous Ic distribution characteristic, quench would be initiated in fixed location on the coil. However, the actual HTS tape has inhomogeneous Ic distribution along the length. If the Ic distribution of the HTS tape is known, we can expect the spot within the HTS coil that has the highest probability to initiate the quench. In this paper, Ic distribution within the HTS coil under self-field effect is simulated by MATLAB. In the simulation procedure, Ic distribution of the entire part of the HTS tape is assume d to follow Gaussian-distribution by central limit theorem. The HTS coil model is divided into several segments, and the critical current of each segment is calculated based on the-generalized Kim model. Single pancake model is simulated and self-field of HTS coil is calculated by Biot-Savart’s law. As a result of simulation, quench-initiating spot in the actual HTS coil can be predicted statistically. And that statistical analysis can help detect or protect the quench of the HTS coil.
