스트레스와 면역기능 간의 관계는 중추신경계, 신경내분비계 및 면역계 간의 의사소통 즉 상호작용에 의해 이루어지고 있다. 중추신경계와 면역계가 상호작용하는 주요 경로는 임파조직의 신경계 wiring system과 신경내분비계다. 면역계는 neuropeptide를 생성하고 이것은 면역반응을 조절한다. 정신사회적 인자와 면역기능 간의 중개자로는 뇌하수체에서 방출되는 peptide, hormone 및 자율신경계 물질이 있다. 시상하부는 내분비계, 신경계 및 면역계를 통합하는 역활을 한다. 특히 시상하부의 paraventricular nucleus가 이 일에 중추적인 역할을 담당한다. 한편 내분비계는 면역계에 의해서 휘이드백을 받는다. 뇌하수체가 면역계를 조절하는 주요 경로로는 시상하부-뇌하수체-부신-흉선축, 시상하부-뇌하수체-성선-흉선축, 송과선-시상하부-뇌하수체축 등이 시사되고 있다. 스트레스와 면역계 간에는 양 방향의 경로가 있는 것으로 가정된다. 즉 스트레스가 면역계에 영향을 미칠 뿐만 아니라 면역계가 정신사회적 기능에 영향을 미칠 수 있다. 따라서 스트레스와 면역기능 간의 관계를 규명하기 위해서는 면역계, 내분비계, 자율신경계 및 뇌활동을 동시에 측정, 비교하여 이들을 통합할 필요가 있다.

This paper reviews and assesses the analogy between the human immune system and network intrusion detection systems. The promising results from a growing number of proposed computer immune models for intrusion detection motivate this work. The paper begins by briefly introducing existing intrusion detection systems (IDS's). A set of general requirements for network-based IDS's and the design goals to satisfy these requirements are identified by a careful examination of the literature. An overview of the human immune system is presented and its salient features that can contribute to the design of competent network-based IDS's are analysed. The analysis shows that the coordinated actions of several sophisticated mechanisms of the human immune system satisfy all the identified design goals. Consequently, the paper concludes that the design of a network-based IDS based on the human immune system is promising for future network-based IDS's

As an approach to develope a control system with robustness in changing control environment conditions, this paper will propose a robot manipulator control system using multilayer neural network and immune algorithm. The proposed immune algorithm which has the characteristics of immune system such as distributed and anomaly detection, probabilistic detection, learning and memory, consists of the innate immune algorithm and the adaptive immune algorithm. We will demonstrate the effectiveness of the proposed control system with simulations of a 2-link robot manipulator.

In this paper, we optimize distributed autonomous robotic system based on artificial immune system. Immune system has B-cell and T-cell that are two major types of lymphocytes. B-cells take part in humoral responses that secrete antibodies and T-cells take part in cellular responses that stimulate or suppress cells connected to the immune system. They have communicating network equation, which have many parameters. The distributed autonomous robotics system based on this artificial immune system is modeled on the B-cells and T-cells system. So performance of system is influenced by parameters of immune network equation. We can improve performance of Distributed autonomous robotics system based on artificial immune system.

Artificial immune systems (AIS) are one of natural computing inspired by the natural immune system. The fault detection, the pattern recognition, the system control and the optimization are major application area of artificial immune systems. This paper gives a concept of artificial immune systems and useful techniques as like the clonal selection, the immune network theory and the negative selection. A concise survey on the optimization problem based on artificial immune systems is generated. The overall performance of artificial immune systems for the optimization problem is discussed.

In the biological immunity, the immune system of organisms regulates the antibody and T-cells to protect the attack from the foreign materials which are virus, germ cell, and other antigens, and supports their stable state. It has similar characteristics that has the adaptation and robustness to overcome disturbances and to control the plant of engineering application. In this paper, we build a model of the T-cell regulated immune response mechanism. We have also designed an immune response controller(IRC) focusing on the T-cell regulated immune response of the biological immune system that include both a help part to control the response and a suppress part to adjust system stabilization effect. We show some computer simulation to control the vibration of building structure system with strong wind forces excitation also demonstrate the efficiency of the proposed controller for applying a practical system even with existing nonlinear terms.

노화는 광범위한 생리 변화이다. 노화가 진행됨에 따라 면역반응은 쇠퇴하고 조절장애가 나타나는데 이를 포괄적 의미로 immunosenescense라고 정의한다. 내재면역반응과 적응면역 반응 모두의 면역 성분은 노화가 진행됨에 따라 영향을 받아 감염성 질병에 대한 취약성이 증가하게 된다. 노화된 동물 모델과 인간에서 면역 세포의 수와 용해성 면역 인자의 양이 줄어 들었고, 면역체계의 기능이 감소하였고, 구조적인 변형과 퇴화가 나타났다. 또한, 세포 내 신호분자와 같은 내재적 변화도 발견되었다. 최근 노화와 관련된 연구는 급격히 증가하였고, 면역체계 영역을 포함하여 다양한 방향으로 노화현상을 분석하는 진보된 기술들이 개발되고 있다. 이 총설은 면역의 주요 구성 요소의 노화 관련 변화에 대한 광범위한 개요를 제공하고자 하였다.

In this paper, we proposed two types of adaptive control mechanism which is named HIA(Humoral Immune Algorithm) PID and CMIA(Cell-Mediated Immune Algorithm) controller based on biological immune system under engineering point of view. The HIA PID which has real time control scheme is focused on the humoral immunity and the latter which has the self-tuning mechanism is focused on the T-cell regulated immune response. To verify the performance of the proposed controller, some experiments for the control of AGV which is used for the port automation to carry container without human are performed. The experimental results for the control of steering and speed of an AGV system illustrate the effectiveness of the proposed control scheme. Moreover, in that results, proposed controllers have better performance than other conventional PID controller and intelligent control method which is the NN(neural network) PID controller.

Thousands of literatures have described the diverse role of ginseng in physiological processes such as cancer, neurodegenera tive disorders, insulin resistance, and hypertension. In particular, ginseng has been extensively reported to maintain homeostasis of the immune system and to enhance resistance to illness or microbial attacks through the regulation of immune system. Immune system comprises of different types of cells fulfilling their own specialized functions, and each type of the immune cells is differentially influenced and may be simultaneously controlled by ginseng treatment. This review summarizes the current knowledge on the effects of ginseng on immune system. We discuss how ginseng regulates each type of immune cells including macrophages, natural killer cells, dendritic cells, T cells, and B cells. We also describe how ginseng exhibits beneficial effects on controlling inflammatory diseases and microbial infections.
