Since realtime search keywords of portal sites are arranged in descending order by instant increasing rates of search numbers, they easily show issues increasing in interests for a short time. But they have the limits extracted different results by portal sites and not shown issues by a period. Thus, to find key issues from the whole realtime search keywords for certain period, and to show results of summarizing them and analyzing differences, is significant in providing the basis of understanding issues more practically and in maintaining consistency of them. This paper analyzes differences of week key issues extracted from week analysis of realtime search keywords provided by two typical portal sites. The results of experiments show that the portal group means of realtime search keywords by the independent t-test and the survival functions of realtime search keywords by the survival analysis are statistically significant differences.

The purpose of this study is to investigate the effect of the level of participation in sports for the disabled on the community attachment. The subjects of this study were 227 persons with physical disabilities in D city. The analysis method was analyzed by factor analysis, frequency analysis, independent t-test, one-way ANOVA and multiple regression analysis using SPSS 21.0 program. The results of this study are as follows: First, there is a high level of community attachment to male(sex), 40's and 50's(by age group) and 1st and 2nd grade(by disability grade). Second, in the degree of participation, the duration of exercise and duration of exercise, duration of exercise in dependency, and duration of exercise and intensity of exercise were found to have a positive effect on identity. As a result, it affected the consciousness of local community. In future research, it is necessary to study the psychological effect connected with community.

This study was conducted to analyze the actual utilization rate of the deposit for defect repair of apartment complexes and its influential factors. We analyzed the data on enforced defect deposit cases by using one-sample t-test, Pearson's correlation analysis, and simple linear regression analysis. The difference between the deposit amount specified and the enforcement amount actually disbursed was found to about 0.51%. The change rates for short-term costs amounted approximately to $839KRW/m^2$ and 130,000 KRW/household per year, and those for long-term costs were $647KRW/m^2$ and 123,207 KRW/household per year. The results warrant the need for further research on establishing a deposit amount based on actual statistical data.

A very important part in vibration analysis is to calculate the frequency response function (FRF). In general, a large sized or/and complicated structure has many thousands to millions of degrees. Therefore, the FRF cannot be calculated by the traditional analysis method using an inverse matrix. This paper presents a new FRF calculation method of a superstructure by synthesizing sub-structure modes, of which the DOF can be deduced by partitioning into some sub-structures. To confirm its analysis results, the method was applied to an assembled plate ($B300{\times}L900{\times}t5mm$) with three diagonal sub-plates($B300{\times}L300{\times}t5mm$) in series and compared with the measured data. The test results have were comparable those of the calculated ones with an error less than 5%.

The aim of this study was to measure preservice teachers' perceptions of Technological Pedagogical Content Knowledge (TPACK). The researcher analyzed responses on the TPACK scale of 307 students in A University located in Chungcheongbuk-do. During the statistical analysis, IBM SPSS 21 program was used to implement Independent Samples T-test, One-way Analysis of Variance, and Multiple Regression Analysis (Enter method). The results are as follows. First, for the mean difference by gender, the mean of female students was higher than that of male students in Pedagogical Knowledge, Pedagogical Content Knowledge, Technological Pedagogical Knowledge, and Technological Pedagogical Content Knowledge. Second, for the mean difference by grade level, the mean of the 1^st, 3^rd and 4^th graders was higher than that of the 2^nd graders in the Content Knowledge at a statistically significant level. Third, toward Technological Pedagogical Content Knowledge, Pedagogical Knowledge of .11 beta value, Pedagogical Content Knowledge of .11 beta value, and Technological Pedagogical Knowledge of .715 beta value were found to be statistically significant predictors. Finally, the researcher discussed development of the TPACK implementation manual and workbook and provision of various technology practice opportunities.

South Korea's economic growth was rapid, It was occasioned the concentration of resources in the metropolitan area. On the other hand, the province has a narrow economic base compared to the metropolitan area, and the underpopulation have been identified. Thus, The government announced the 'National balanced development law' in 2004 to reduce the problem of regional imbalances. The study collected data on 95 of relocated public institutions, and unlike previous studies, Mamquist analysis was used to compare the productivity before and after each public institutions' s relocation. The study focused on how the relocation of public institutions affected the productivity of public institutions through Malmquist Analysis. The results of the analysis show that productivity is declining after most public institutions have moved. And two independent samples T-test result, respective yearly average is nonsignificant.

This study conducted t-test and ANOVA analysis, influence of importance-satisfaction, regression analysis to local food and restaurants to the purchase intention in Busan. The subjects of this study were tourists who visited local restaurants in Busan, and the final 392 copies were used for empirical analysis. As a result of the study, first, there will be a significant difference in the recognition of local foods in Busan according to the visitor's region. In all samples, the recognition was high in the order of pork stock, wheat noodle, sauteed·fired soft eel, grilled·ell sashmi. On the other hand, sansung bulgogi, Dongrae pajeon, and sansung makkŏlli were the lowest. Second, in the difference between importance and satisfaction of local restaurants in Busan, 'there is a different taste compared to other regions' showed high satisfaction and importance. Third, In the relationship between the awareness of local restaurants in Busan and the purchase intention, it was found to be effective in service, facilities, prices and locality and cleanliness were rejected.

This study was done develop the factors that affect the quality of life among pregnant women supportive, stress and anxiety. This study was a descriptive survey of 117 pregnant women residing in two regions D and S. Before the questionnaire, the purpose and purpose of the study were explained and proceeded SPSS 21.0 was used for the data, frequency analysis, variance analysis, t-test, correlation analysis, and rare analysis. The data was collected from January to February 2020. The results of this study are as follows. The differences in quality of life of pregnant women according to general characteristics showed significant differences in sleep time, economic status, health status, activity status and pregnancy cycle. Variables affecting quality of life were social support (β= .432, p= .000), pregnancy stress (β=- .407, p= .000), anxiety (β=- .182, p= .010). If pregnant women experience pregnancy stress and anxiety, the quality of life may be degraded, so it is necessary to develop a health promotion program for pregnant women.

This research has reviewed the ways to improve the benefits of shortening of transit hours among the benefit items in analysis of economic efficiency. The existing way of calculating the benefits of shortening the transit hours in analysis of economic efficiency has been using O/D in peak to multiply by 365. This method has a problem of not considering the change of traffic according to the month and the day of the week. To improve such problem, the volume of traffics at 361 regular research branches of the chronological statistics of traffic volume was used to analyze the pattern change of traffic volume per day of the week and per month by t-test and cluster analysis. The results show a difference in traffic volume according to the day of the week and the month. In the research example, a supposed O/D and network were used to apply weight per day of the week and per month to see a slight difference with the existing method of calculating benefits of shortening the transit hours. This signifies the necessity to study about the weight to consider the change pattern of traffic volume.
