This study is using Factor Analysis method to analyze the hydrographs of groundwater table for classification of recharge zone. The water table data are taken from 37 wells which located on unconfined aquifer in Pingtung plain. The result shows that 93% of total variance can be explained by three components. The 1th component is related to rainfall; the 2th and 3th are related to recharge from TungKang Basin and Kaoping basin, respectively.

Research background and hypothesis. Factor analysis method enables to reveal the complex of dominating indicators determining the competitive result, as well as to define extend of interrelation between indicators and establish the role of individual factors important in the achievement of sports result.  The aim of this study was to reveal manifestations of factors of technical-tactical actions determining success of football teams taking part in the country’s championship.Research methods. The study participants were 24 football players from elite level “Aktobe” team, playing in Kazakhstan Premier League and the champion of Kazakhstan. The technical-tactical actions was analysed separately and compared during the first and the second rounds of the championship (1 1 games in each round). Research results. The analysis of factor contribution into the structure of technical-tactical actions in the first and the second rounds of the country’s championship showed that during the second round of the championship the volume of technical-tactical actions, indicating the possession of play initiative, decreased from 49.6 to 44.1% of total variance, but the contribution of technical-tactical actions, indicating completing of team’s attacking actions, increased from 16.5 up to 24.8% of total variance. It enabled the team to score more goals in the second round of the championship. Discussion  and  conclusions.  Pursuant  to  the  factor  analysis,  such  indicators  as  “short  and  medium  passes forward”, “long passes”, “interceptions”, “hitting the goals” and “total number of technical-tactical actions” are dominating parts of the integral factor – “Possession of play initiative”. Quantifying all the activities of individuals, group of players and of the entire team, which contributed to achievement of elite football teams, is essential in programming and managing the training process.Keywords: football, game analysis, technical and tactical preparation.

Auditory Processing

This study was concerned with the correspondence between the classification of measures by clinical judgment and by factor analysis. Forty-six measures were selected to assess language, auditory processing, reading-spelling, maxillofacial structure, articulation, and other processes. These were applied to 98 misarticulating eight- and nine-year-old children. Factors derived from the analysis corresponded well with categories the measures were selected to represent.

Groundwater table rising (GTR) represents a well-known issue that affects several urban and agricultural areas of the world. This work addresses the link between GTR and the formation of solute plumes from contaminant sources that are located in the vadose zone, and that water table rising may help mobilize with time. A case study is analyzed in the stratified pyroclastic-alluvial aquifer near Naples (Italy), which is notoriously affected by GTR. A dismissed chemical factory generated a solute plume, which was hydraulically confined by a pump-and-treat (P&T) system. Since 2011, aqueous concentrations of 1,1-dichloroethene (1,1-DCE) have been found to exceed regulatory maximum concentration levels in monitoring wells. It has been hypothesized that a 1,1-DCE source may occur as buried waste that has been flushed with time under GTR. To elucidate this hypothesis and reoptimize the P&T system, flow and transport numerical modeling analysis was developed using site-specific data. The results indicated that the formulated hypothesis is indeed plausible. The model shows that water table peaks were reached in 2011 and 2017, which agree with the 1,1-DCE concentration peaks observed in the site. The model was also able to capture the simultaneous decrease in the water table levels and concentrations between 2011 and 2014. Scenario-based analysis suggests that lowering the water table below the elevation of the hypothesized source is potentially a cost-effective strategy to reschedule the pumping rates of the P&T system.
