About the Lab
Professor Dongsu Kim's research spans mathematical physics, combinatorics, and organizational theory, with a strong focus on orthogonal and biorthogonal polynomials, inversion sequences, and their combinatorial interpretations. His work in mathematical physics centers on dynamic systems such as centrifuge-based earthquake simulators, while his combinatorial research explores deep connections between special polynomials, lattice paths, and integer sequences like Catalan, Schröder, and Baxter numbers. He also investigates theoretical foundations in organizational studies, particularly through the lens of institutional deconstruction in institutional theory. His interdisciplinary approach bridges discrete mathematics, theoretical physics, and social science through rigorous combinatorial and structural analysis.

15This paper describes some details of a self-balanced earthquake simulator on the centrifuge in KAIST and results of a series of proof tests for verifying its dynamic performance and excitation capacity. The main feature of the earthquake simulator is the dynamic self-balancing technique adopted to eliminate a large portion of the undesired reaction forces and vibrations transmitted to the centrifuge main body. This feature is achieved by embarking counter-weight platform and two back-to-back hyd
We describe various aspects of the Al-Salam-Chihara q-Charlier polyno- mials. These include combinatorial descriptions of the polynomials, the moments, the orthogonality relation and a combinatorial proof of Anshelevich's recent result on the linearization coecients.
Recently, the study of patterns in inversion sequences was initiated by Corteel-Martinez-Savage-Weselcouch and Mansour-Shattuck independently. Motivated by their works and a double Eulerian equidistribution due to Foata (1977), we investigate several classical statistics on restricted inversion sequences that are either known or conjectured to be enumerated by {\em Catalan}, {\em Large Schröder}, {\em Baxter} and {\em Euler} numbers. One of the two highlights of our results is a fascinating bije
본 논문은 지난 40여 년간 진행된 신제도주의 조직이론 연구를 제도적 디커플링 개념에 초점을 맞추어 검토한다. 신제도주의는 대표적인 조직이론 패러다임으로 국내외 조직연구에서 확고한 입지를 차지하고 있으나, 새로운 이론 패러다임의 도출 및 검증이나 다른 패러다임 간 대화와 통합에 미치는 근본적인 기여 측면에서 학문적 입지에 걸맞은 영향력을 앞으로도 유지해 나갈 수 있을 것인지 의문도 제기되는 상황이다. 제도적 디커플링 개념은 신제도주의 조직이론의 가장 초기 시점부터 등장하여 최근까지 수많은 연구에 활용되기에 이러한 상황을 신제도론이 발달한 역사적 맥락에서 조망하는 데 유용하다. 본 논문은 제도적 디커플링 개념이 신제도주의 조직이론에서 갖는 의미를 논의하되, 관련 연구 동향을 단순 소개하는 것에서 벗어나 지금까지 연구가 신제도론의 핵심주장을 명확하게 반영하고 이론 패러다임의 확장에 기여했는지 근본적 수준에서 재고찰한다. 신제도주의 조직이론에 따르면 조직은 사회구성원이 바람직하고 당연하다
A combinatorial bijection between $k$-edge colored trees and colored Prüfer codes for labelled trees is established. This bijection gives a simple combinatorial proof for the number $k(n-2)!{nk-n\choose n-2}$ of $k$-edge colored trees with $n$ vertices.
