Motif

The artistic background of the Good Shepherd motif can be traced to ancient eras of the East and the West. This motif later gained prominence in early Christian art. The ram-bearer (carrying a sacrificial or an offering animal) first appeared in Near Eastern art and later became an important motif in Greco-Roman art to represent certain roles of the god Hermes. This motif was considered by Christian converts as a symbol of Jesus Christ, as they represented him in the figure of a young shepherd caring for his flock. This theme can also be seen on some Sasanian seals, which can be considered as the Good Shepherd motif. In this article, the authors introduce the aforementioned motif depicted on these seals and examine their possible connection with the Christian communities. The motif of the Good Shepherd, as seen on the seals, demonstrates modifications in the original iconography. These changes can be observed in the longer dress of the ram-bearer or the engraving of celestial symbols. These modifications are probably a sign of the localization process of an imported motif in the Sasanian Empire.

Statistics, extraction, analysis are vital in sports science. Information technology and data science will significantly increase the quality of research and decisions of sports clubs and organizations. Currently, many coaches and sports institutions use analytics and statistics that are calculated manually. Sports science shows that winning a match depends on different factors. The purpose of the research is to improve team performance by analyzing social networks, communication networks (such as players' passes and transactions during the match), and analyzing repetitive areas. These results are done by analyzing the data collected from 4 matches of the Persepolis team, including three matches from the first half of the Iranian Premier League in 2018-1399 and a Persepolis match against Al-Sharjah. This research examines the issue from two interconnected aspects: 1- Examining the performance of players individually and as part of a social network. 2- explore the communication network between players and land areas. This analysis uses the innovative method of identifying and classifying motifs.
