In this paper, The infrastructure case for reproduction or analysis of the mechanism on the fire or the electrics shock of the electrical appliances is proposed. The various electrical appliances(Washing machine, Ballast, Electric heaters, Electronic switches, Mobile phone chargers) used in the home can be tested on the high voltage and over current test through the implementation of the infrastructure. The electrical tests of fire and electric shock consists of the high voltage of maximum 5000 V and over current test of 3 steps(90 A, 60 A, 40 A) and noise test. The mechanism of the fire and the electric shock tests reproduced are analyzed through the monitoring system and the oscilloscope. The electronics manufacturers can prevent accidents through the tests of the electronics factor reproduced and the analysis of the infrastructure designed.

It's general a trend to use the load/unload mechanism in the small form factor HDD, like 2.5", 1.8" and 1.0". The load/unload mechanism has tittle opportunity of head/media contact during the disk spin-up and down. However, the load/unload mechanism needs the precise integration technology with slider, suspension ramp, load/unload velocity and so on, and all of these components should be designed simultaneously, not an individually. In this paper, we measured the load/unload velocity in the drive level, and executed the load/unload dynamics with this velocity profiles. We could find the current load/unload mechanism suitable to the long load/unload test.

One factor that can heighten the risk of the rapture intracranial aneurysm (IA) is bifurcations, which can cause the IA to evaluate. This study presents the effect of geometric of intracranial vascular on the bifurcation analysis of the aneurysm occurrence. The aneurysm mechanism is mathematically modeled based on the nano pipe structures under the thermal stresses, and the impact of the aneurysm geometric on the stability and bifurcation points is analyzed. Because of the dimension of these structures, the classical theories could not predict their behavior perfectly, so the nonclassical and nonlocal theories are required for the mechanical modeling of the aneurysm. The presented results show that the bifurcation point of the aneurysm mechanism is dependent on the environment temperature, and the temperature change plays an essential role in the stability of these structures.

Palmitic acid (PA) is one of free fatty acids, which is found from Gaultheria itoana Hayata and Sarcopyramis nepalensis. Although PA has a variety of pharmacological effects including mediates hypothalamic insulin resistance, induces IP-10 expression, and promote apoptotic activities, the anti-inflammatory mechanism of PA in mouse peritoneal macrophages remains unclear. In this study, we showed that PA exerted an anti-inflammatory action through suppression the production of tumor necrosis factor-$\alpha$, interleukin-6, cyclooxygenases-2 and nitric oxide in lipopolysaccaride-stimulated mouse peritoneal macrophages. Our study suggests an important molecular mechanism of PA, which might explain its beneficial effect in the regulation of inflammatory reactions.

In order to examine the mechanism of asbestos clastogenicity, CHO cells were treated with chrysotile and crocidolite. Crocidolite and chrysotile were able to induce lipid peroxidation in a dose dependent manner. Ultrafiltrate of culture media from CHO cells treated with chrysotile/crocidolite induced sister chromatid exchange in CHO cells. Ultrafiltrate of culture media from CHO cells treated with chrysotile induced chromosome aberration but it was not statistically significant. Simultaneous treatment of 3-Aminobenzamide (3-AB) or cytosine arabinoside (Ara C) with crocidolite had no effect on the frequency of chromosome aberration by crocidolite whetease posttreatment of caffeine significantly increased the chromosomel aberration by crocidolite. This indicated that DNA damage by asbestos took place at late stage of cell cycle. The results suggested that the ultrafiltrate of media contained clastogenic factor (CF) and lipid peroxidation might be involved in the formation of CF.

It is essential in evaluating the chronic pain patients that the physician obtain a multiple causative factors including organic, psychological, and socioenvironmental factors. Though these multiple factors are involved in the development of chronic pain syndrome, chronic pain syndrome is not only the sum of the interaction of all of these factors, but is also influenced by the sequelae of chronic pain, which again are organic, psychological, and socioenvironmental in nature. Therefore a systemic approach is probably the best way to asses the role of all of these factors. Furthermore, this approach can provide a framework for understanding chronic pain syndrome, for assessing chronic pain syndrome, for the rational management of chronic pain syndrome, and for the development and testing of hypotheses.

This paper presents the single-stage high power factor AC to DC converter operated in active-clamp mode. The proposed converter is added active-clamping circuit to boost-flyback single-stage power factor corrected power supply. The active-clamping circuit limits voltage spikes, recycles the energy trapped in the leakage inductance, and provides a mechanism for achieving soft switching of the electronic switches to reduce the switching loss. The auxiliary switch of active-clamping circuit uses the same control and driver circuit as the main switch to reduce the additional cost and size. To verify the performance of the proposed converter, a 100W converter has been designed. The proposed converter gives good power factor correction, low line current harmonic distortions, and tight output voltage regulation, as used unity power factor.

6 sigma is a management innovation strategy which improves most of all managerial processes including transactional and project based operations such as marketing, purchasing, accounting, and construction. Even though 6 sigma is trying to solve problems from the customer's viewpoint in the scientific manner, project leader feels some difficulties in implementation because of several reasons. Especially the difficulties are prevalent in construction site. This paper investigates the cause of the difficulties through questionnaires, analyzes the investigation results, and verifies the critical success factors of 6 sigma implementation. Factor analysis has been usually employed in reducing quantity of data and summarizing information chaos. In this study, several variables from questionnaires are grouped into just only four factors by the process of factor analysis. The critical success factors are extracted as project management system, implementation mechanism, site condition, and project ownership. Some ideas for each individual success factor are suggested, which are expected to be useful in successful implementation of 6 Sigma in construction site.
