  • Angelica gigantis (AG), Rehamaninae Radix(RR), Paenia japonica (PJ), and Polygoni multiflori Radix (PM) have been used as medicinal plants to tonify the blood. General function of the drugs have been known to nourish blood and control the heart and liver meridians. Recently, several studies have proposed mechanisms by which some oriental medicinal herbs work on the immune system. However, it is uncertain whether aqueous-extract of these drugs has immunomodulatory effect yet. In this study, I investigated the immune promotive effects of the water-extracted AG, RR, PJ and PM. The water-extracted AG, RR, PJ and PM inhibited NO production and iNOS expression in LPS stimulated RAW 264.7 macrophage cell line. Among these extracts, AG and PM induced expression of IL-2 and IFN${\gamma}$ in mouse spleen cells. In the flow cytometry analysis, PM-stimulated mouse spleen cells showed an increase in B-cell phenotype (CD45R/B220). The oral administration of Polygoni multiflori water-extracts to mice having S-180 abdominal dropsy cancer prolonged life-span more than control mice. These data suggest that among these extracts, PM has cellular and humoral immune-enhancement effect through IL-2 and IFN${\gamma}$ cytokine production, the regulation of NO production in macrophage cells and the B cell production in spleen cells.

  • In this paper, optimal tuning problem of power system stabilizer(PSS) using Immune Algorithm(IA) is investigated to improve power system dynamic stability. In proposed method, objective function is represented as antigens. An affinity calculation is embedded within the algorithm for determining the promotion or suppression of antibody. An antibody that most fits the antigen is considered as the solution to PSS tuning problem. The computaton performance by the proposed method is compared with Genetic Algorithm(GA). The porposed PSS using IA has been applied for two sample system, single-machine infinite bus system and multi-machine power system. The performance of the proposed PSS is compared with that of conventional PSS. It is shown that the proposed PSS tuned using immune algorithm is more robust than conventional PSS.

  • This study investigated the correlations among nutrient intakes, and immune status in Korean young women in relation to body mass index(BMI). Subjects were classified as underweight, normal or overweight, with anthropometric measurements of these three groups significatly different in terms of weight, body fat, waist measurement, hip measurement, waist/hip ratio(WHR), and skindfold thickness(p<0.001). Average vitamin A, vitamin B1, vitamin B2, calcium and zinc levles were lower than the Korean RDA. Vitamin A levels were found to be significantly correlated with BMI(p<0.05). There was no significant difference in total T and B lymphocytes or IgG, IgG, and IgM levels with respect to BMI, but Natural Killer(NK) cell levels were found significantly increased with increased BMI(p<0.05). BMI was also positively correlated with iron intake and negatively correlated with vitamin A intake in the normal group. Based upon this study, further research on nutritional, immune and trace-mineral status of overweight and underweight young women is required for better health promotion in this female populaton.

  • Immune-potentiation of Chicorium endivia L. were investigated on follows extracts associated with ultrasonification process at 60 kHz and showed the highest promotion of human B and T cell growth, about $10{\sim}20%$ compared to the control. The secretion of TNF-${\alpha}$ and IL-6 was also enhanced by the addition $(0.5mg/m{\ell})$ of the extracts. NK cell activation was Improved up to 1.37 times higher than the control, through adding extracts. It was also found that extracts from C. endivia L. could yield higher nitric oxide production from macrophage than Lipopolysaccaharides (LPS). It can be concluded that, in general, the extracts treated with ultrasonification has higher immune activity than others, possibly by higher yielding immune-modulatory activity than conventional extraction process. The optimum condition for the extraction of C. endivia L. is ethanol extraction at $60{\sim}100^{\circ}C$ associated with ultrasonification.

  • It is essential to study the effects of hypergravity on the human body in the research field of aerospace medicine. Previous studies have shown that hypergravity could act in a harmful way to the human body. However, recent studies have shown that moderate degree of hypergravity can act in a beneficial way to the human body. The authors have in particular been studying the effects of hypergravity on immune diseases, especially allergic asthma and rhinitis. Therefore, this review paper will introduce the results of recent studies on hormetic (health promotion) effect of hypergravity. In addition, this review paper also examines the mechanism by which hormetic effect of hypergravity could be possible. Furthermore, we will also discuss how to apply these hormetic effects in clinical practice.

  • In existing cloud services, information security and privacy concerns have been worried, and have become one of the major factors that hinder the popularization and promotion of cloud computing. As the cloud computing infrastructure, the security of virtual machine systems is very important. This paper presents an immune-inspired intrusion detection model in virtual machines of cloud computing environment, denoted I-VMIDS, to ensure the safety of user-level applications in client virtual machines. The model extracts system call sequences of programs, abstracts them into antigens, fuses environmental information of client virtual machines into danger signals, and implements intrusion detection by immune mechanisms. The model is capable of detecting attacks on processes which are statically tampered, and is able to detect attacks on processes which are dynamically running. Therefore, the model supports high real time. During the detection process, the model introduces information monitoring mechanism to supervise intrusion detection program, which ensures the authenticity of the test data. Experimental results show that the model does not bring much spending to the virtual machine system, and achieves good detection performance. It is feasible to apply I-VMIDS to the cloud computing platform.

  • Prebiotics are defined as substrates that are selectively utilized by host microorganisms conferring various health benefits. Current prebiotic researches not only focus on non-digestible oligosaccharides, but also extend to polyphenols and peptides. However, the extended scope of prebiotic research pertains its original purposes: promotion of beneficial bacteria in host guts and production of valuable metabolites. Maintenance of optimal gut microflora plays a key role in host health care benefits including anti-cancer activity, immune response modulation, blood lipid level reduction, increased mineral absorption, and weight loss. With increasing probiotics markets, prebiotics have also received much attention in functional food markets. Hence, many global food companies tempt to develop new prebiotics applicable for preventing human diseases as well as modulating immune system. In this review, we discuss current status of prebiotics research, market progress, and future perspectives of prebiotics.
