About the Lab

Professor Lee Yoon-Jin's research spans interdisciplinary domains, focusing on bioactive natural products and their metabolic impacts, particularly in obesity and mitochondrial health. Her work also extends into statistical modeling of non-negative time series, especially multiplicative error models with flexible conditional moments. Additionally, she investigates signal processing and radar-based target recognition using statistical distributions of radar cross-section data.

Chrysanthemum morifolium Flower Extract Ameliorates Obesity-Induced Inflammation and Increases the Muscle Mitochondria Content and AMPK/SIRT1 Activities in Obese Rats

SJR Q1NutrientsOA

Decreased energy expenditure and chronically positive energy balance contribute to the prevalence of obesity and associated metabolic dysfunctions, such as dyslipidemia, hepatic fat accumulation, inflammation, and muscle mitochondrial defects. We investigated the effects of Chrysanthemum morifolium Ramat flower extract (CE) on obesity-induced inflammation and muscle mitochondria changes. Sprague–Dawley rats were randomly divided into four groups and fed either a normal diet, 45% high-fat diet (H

SJR Q1Journal of Time Series Analysis

We develop a general theory to test correct specification of multiplicative error models of non-negative time-series processes, which include the popular autoregressive conditional duration (ACD) models. Both linear and nonlinear conditional expectation models are covered, and standardized innovations can have time-varying conditional dispersion and higher-order conditional moments of unknown form. No specific estimation method is required, and the tests have a convenient null asymptotic N(0,1)

RCS based target recognition with real FMCW radar implementation
Yoonjin Lee, Hosung Choo, Soojin Kim, Hongseok Kim
SJR Q3Microwave and Optical Technology Letters

In this article, we investigate the methods that can realize automatic target recognition and tracking by exploiting signal distribution of radar cross section (RCS) with frequency modulated continuous wave (FMCW) radar. In doing this we use the real RCS data measured from the short-range FMCW vehicle radar. We estimate the continuous valued degree of freedom and the mean of RCS distribution using maximum likelihood estimation (MLE) assuming that RCS follows gamma distribution. The experiments w

Computation of the Fundamental Units and the Regulator of a Cyclic Cubic Function Field
Yoonjin Lee, Renate Scheidler, C. Yarrish
SJR Q1Experimental Mathematics

Abstract This paper presents algorithms for computing the two fundamental units and the regulator of a cyclic cubic extension of a rational function field over a field of order q ≡ 1 (mod 3). The procedure is based on a method originally due to Voronoi that was recently adapted to purely cubic function fields of unit rank one. Our numerical examples show that the two fundamental units tend to have large degree, and frequently, the extension has a very small ideal class number. Keywords: Purely c

색채감성에 대한 판단에 있어서의 일반인과 전문가의 차이 - 색상과 톤에 의한 영향을 중심으로 -
이윤진, 이나경, 김수정

본 연구에서는 색채감성에 대한 판단에 있어서 색상과 톤이 미치는 영향을 일반인과 전문가 간에 비교 분석하기 위하여 43개의 감성어휘를 평가척도로 하여 35색의 단색에 대해 주관평가실험을 실시했다. 그 결과 이하의 특징이 확인되었다. 첫째, 전문가 그룹은 일반인 그룹보다 색자극 군의 차이와 그에 따른 감성의 변화에 대한 식별력이 높아서 색채에 대한 감성을 비교적 섬세하게 판단할 수 있었다. 둘째, 색상과 톤을 색채감성에 대한 판단의 기준이 되는 요인으로 설정하여 두 그룹에 어떤 영향을 미치는지 반복측정 분산분석을 통해 검토하였다. 그 결과 색채감성에 대한 판단은 색상 보다 톤에 의한 영향이 크다는 것을 확인했고 톤요인에 의한 두 그룹 간의 차이가 있다는 점이 확인되었다. 셋째, 일반인 및 전문가 그룹이 색상과 톤을 기준으로 색채감성에 대하여 어떤 차원을 이루고 있는지 다차원척도법(MDS)을 이용하여 분석하였다. 2차원 MDS 플롯으로 해석한 결과 전문가 그룹에서 톤을 기준으로 하는 차
