Aims and Scope

The origin of New Physics: Sae Mulli (NPSM, ISO abbreviation: New Phys.: Sae Mulli.): Sae Mulli (새물리 in Korean characters means ‘new physics’) is the oldest Korean pure scientific journal. It was first published in 1961 just after the Korean War by the Korean Physical Society (KPS). The primary mission of Sae Mulli was to start building up Korean physics research community from almost nothing and in fact Sae Mulli had made tremendous contributions to the Korean science community. Through a peer-review system, Sae Mulli had continued elevating the level of scientific researches, consequently becoming a cornerstone of the economic miracle of Korea...

This study uses network methodology to examine the clustering of equity funds in the Korea stock market. Unlike a number of previous studies that used the econometric model to analyze the role of fund managers in financial markets, we use the complex network method. In this study, we use the net asset value (NAV) of the fund to measure the similarities between Korea equity funds and to extract a minimum spanning tree (MST) network from a complete graph. Previous studies, which used individual firms in the financial market, showed a power-law distribution in which hub characteristics were observed; in particular they showed a phenomenon of clustering by industry sector. Here, we consider whether the network of Korea equity funds follows a power-law distribution, especially whether it affects the cluster phenomenon of the asset management company in the different economic states. Our results indicate that the structure of the fund network follows a power-law distribution regardless of the sample period. Especially, we find that the grouping phenomenon of asset management companies in the fund network varies during different financial states.

Baseball is a game of numbers. Large-scale baseball data have been utilized in decision making process by team managers. Recent studies with PITCHf/x, a system that tracks every pitch, provide new insights on the role of the pitch-type sequence in the pitcher's performance. These studies are based on the assumption that the pitch-type uncertainty puts the hitter at a disadvantage. However, the pitch-zone uncertainty, another factor of pitching uncertainty, is neglected in many cases. Here, we introduce normalized mutual information for pitch type and pitch-zone as an indicator of pitching uncertainty. A pitcher with less of a repertoire with respect to type-zone combination has high normalized mutual information in pitching. We calculate the pitch type - zone uncertainties for major league baseball starting pitchers and compare the results with field independent pitching, a metric of pitcher's performance. Our analysis shows that normalized mutual information is uncorrelated with performance in nine distinct subgroups extracted from revealed comparative advantage in pitch type. This result underlines the importance of the pitcher's repertoire and ability to be competitive in professional baseball.
