Abstract
In the paper, the effects of sidecar on the Korean stock market are considered. Throughout the study, we could reach the following conclusions. Firstly, the analysis of return dynamics illustrates that there are no price reversals for all sample groups but price continuations after the event. Secondly, the analysis of volatility and liquidity shows that there are some differences in the effects of sidecar on market volatility and liquidity according to the sample periods‘ however, in the post period of widening of the sidecar trigger levels, the mechanism couldn’t play any role of stabilizing the market volatility and resolving the increased order imbalance around the event. From these results, we could infer that sidecar delays the normal price discovery process and undermine the market liquidity. Also, we suggest that the increased market efficiency of Korea stock market after the financial crisis in 1997, especially deregulation in securities markets, can be a good additional factor for explaining the diffrences in the role of sidecar between sample periods.

Abstract
This chapter aims to build a systematization of the current theoretical and empirical academic contributions on smart working (SW) in the organization studies domain and to examine which are the main paths that researchers are concerning themselves with, with specific attention being paid to the new meaning that the work itself has acquired in the model proposed by SW. Particular consideration is devoted to an analysis of the characteristics of the present debate on this construct and the meaning of SW, identifying two different – and contrasting – approaches: one considers it as a totally new concept; the other is notable for its continuity with previous arrangements such as telework. Further, some relevant concepts, strictly related to that of SW in working environments are considered. In the last part of the chapter, some key points for further research are proposed to create stimuli for discussion in the community of organization studies and HRM scholars and among practitioners, given from the perspective of deepening the change in progress, the relevance for which there is general consensus.

Abstract
This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.
