식물대사체학은 식물세포, 조직, 기관, 혹은 개체수준에서 주어진 시간과 조건에서 발견되는 모든 대사물질을 밝히고, 시간의 경과 혹은 조건의 변화에 따른 metabolic profiling의 변화를 연구하는 식물학 분야이다. 식물대사체학은 생물에 대한 전체론적 접근을 위한 가장 최근에 발달된 omics분야의 하나로서 일종의 시스템 생물학이다. 전체론적 접근과 이해를 위해서 대사체학은 metabolic profiling의 계량화학 혹은 다변량분석 방법을 자주 사용한다. 식물학분야에서 대사체학은 애기장대나 벼와 같은 모델식물에 tag를 도입하여 형질전환시킨 돌연변이체에 대해 DNA microarray와 함께 사용하여 유전자의 기능을 밝히는데 유용하게 사용된다. 본 총설에서는 식물대사체학의 기본 개념과 1H NMR 혹은 FTIR으로 얻은 metabolic profiling의 다변량분석에 대한 실용적인 사용법을 소개하고자 하였다. Plant metabolomics is a plant biology field for identifying all of the metabolites found in a certain plant cell, tissue, organ, or whole plant in a given time and conditions and for studying changes in metabolic profiling as time goes or conditions change. Metabolomics is one of the most recently developed omics for holistic approach to biology and is a kind of systems biology. For holistic approach, metabolomics frequently uses chemometrics or multivariate statistical analysis of metabolic profillings. In plant biology, metabolomics is useful to determine functions of genes often in combination with DHA microarrays by analyzing tagged mutants of the model plants Arabidopsis and rice. This review paper attempted to introduce basic concepts of metabolomics and practical uses of multivariate statistical analysis of metabolic profiling obtained by $^1$H HMR and Fourier transform infrared spectrometry.

In this paper, we propose an autonomous steering real vehicle control logic based on discrete time sliding mode control logic. As new ADAS logics are continuously developed, the need to develop EPS logic, which is a sub-actuator, is increasing. Also, When integrating multiple ADAS logics, its management through efficient model-based design is required. In this study, the process of verifying the development of EPS logic based on MATLAB/Simulink, which is composed of steering dynamics model was performed. The feasibility and development process of this logic was demonstrated by the real vehicle Niro, a small SUV of Kia Motors.

In order to improve the cornering stability of the vehicle, the information about the vertical tire force and roll angle is required. So many researches have been conducted using a roll angle estimator based on Extended Kalman Filter (EKF). However, its performance drops sharply in various driving and road environments, because of the nonlinearity of bicycle model. Thus, we propose more robust roll angle estimator based on Unscented Kalman Filter (UKF) algorithm for the lateral acceleration nonlinearity change of vehicle

In this paper, we present the integrated Active Front Steering (AFS) control system using roll dynamics of vehicle. Many previous studies have integrated AFS with ESC to improve vehicle cornering stability. However, deceleration due to the sudden braking caused unnecessary moments, which required many control variables. In this study, we developed the integrated AFS control by minimizing the variables during cornering. It is composed of steering and speed control considering roll dynamics of vehicle. In the conclusion we found that this control system prevented roll over and improved cornering stabiltiy.
전기식 동력 조향 특성을 고려한 3-자유도 능동 전륜 조향 제어기 설계

In this paper, we presented the 3-DOF active front wheel steering controller considering Electric Power Steering (EPS) characteristics. In the previous study, we performed 3-DOF active front steering control based on angle control. However, since the actual vehicle has an EPS structure, torque control must be performed together. Therefore, we modeled the EPS system and designed a torque controller with sliding mode control. This active front steering control was designed by using MATLAB/Simulink and its performance was demonstrated by CarSim, a vehicle dynamics program.
