Herniated nucleus pulpous(HNP) on lumbar spine is one of work-related musuloskeletal disorders. We evaluated a worker diagnosed HNP with some ergonomics tools to identify work-related risk factors at his workplace. One tool is are mainly developed to evaluate lumbar disc pressure of 5th lumbar on 1st sacral spine. We used another tool to evaluate lumbar posture. The worker's main job is heavy material lifting and handlings. The results show us that his work can be a musculoskeletal body burden of his low back such as pressure over 3,400N. Finally, We suggested some recommendations to improve his working conditions and prevent his disorder

Lateral epicondylitis is one of work-related musculoskeletal disorders. We evaluated a worker who diagnosed lateral epicondylitis with some ergonomics tools to identify work-related risk factors at his workplace. The worker's main job is drawing up a design using a CAD(computer aided design) program. The CAD job shows us that investigation and changes are required soon as an action level. We suggested some recommendations to improve his working conditions and prevent his disorder.

${\alpha}$-Iso-cubebene (ICB) is a dibenzocyclooctadiene lignin contained in Schisandra chinensis (SC), a well-known medicinal herb that ameliorates cardiovascular symptoms, but the mechanism responsible for this activity has not been determined. To determine the role played by ICB on the regulation of vascular tone, we investigated the inhibitory effects of ICB on vascular contractile responses by adrenergic ${\alpha}$-receptor agonists. In addition, we investigated the role on myosin light chain (MLC) phosphorylation and cytosolic calcium concentration in vascular smooth muscle cells (VSMC). In aortic rings isolated from C57BL/6J mice, ICB significantly attenuated the contraction induced by phenylephrine (PE) and norepinephrine (NE), whereas ICB had no effects on KCl (60 mM)-induced contraction. In vasculatures precontracted with PE, ICB caused marked relaxation of aortic rings with or without endothelium, suggesting a direct effect on VSMC. In cultured rat VSMC, PE or NE increased MLC phosphorylation and increased cytosolic calcium levels. Both of these effects were significantly suppressed by ICB. In conclusion, our results showed that ICB regulated vascular tone by inhibiting MLC phosphorylation and calcium flux into VSMC, and suggest that ICB has anti-hypertensive properties and therapeutic potential for cardiovascular disorders related to vascular hypertension.

The purpose of the study was to predict conflict-inducing factors among family members through examining such factors caused during family travel in our nation and providing basic data for researching travel behaviors through identifying different conflict-inducing factors during changed family travel. So, most of all, this study examined different conflict-inducing factors between a decision-maker and each family member by family life-cycle during family travel in terms of tourism science, in other words, of understanding tourist behaviourism. Accordingly, firstly it is expected that smooth communication among each stakeholder will be done during decision-making on family travel. Secondly, it is expected that mutual trust will be established through convergence of opinions among stakeholder. Thirdly, it is expected that trial and error during familial decision-making will be prevented through predicting conflict-inducing factors among family members.

<P>A simple fabrication route for ion gel nanofibers in a triboelectric nanogenerator was demonstrated. Using an electrospinning technique, we could fabricate a large-area ion gel nanofiber mat. The triboelectric nanogenerator was demonstrated by employing an ion gel nanofiber and the device exhibited an output power of 0.37 mW and good stability under continuous operation.</P>

Mercury occurs in various chemical forms, and it is different to health effects according to chemical forms. In consideration of the point, the evaluation of the mercury exposure to human distinguished from occupational and environmental exposure. With strict to manage occupational exposure in factory, it is declined mercury intoxication cases by metallic and inorganic mercury inhalation to occupational exposure. It is increasing to importance in environmental exposure and public health. The focus on the health impact of exposure to mercury is more on chronic, low or moderate grade exposure—albeit a topic of great controversy—, not high concentration exposure by methylmercury, which caused Minamata disease. Recently, the issue of mercury toxicity according to the mercury exposure level, health effects as well as the determination of what mercury levels affect health are in the spotlight and under active discussion. Evaluating the health effects and Biomarker of mercury exposure and establishing diagnosis and treatment standards are very difficult. It can implement that evaluating mercury exposure level for diagnosis by a provocation test uses chelating agent and conducting to appropriate therapy according to the result. but, indications for the therapy of chelating agents with mercury exposure have not yet been fully established. The therapy to symptomatic patients with mercury poisoning is chelating agents, combination therapy with chelating agents, plasma exchange, hemodialysis, plasmapheresis. But the further evaluations are necessary for the effects and side effects with each therapy.
