By Literatural studying on migraine, The results were obtained as fallow : 1. A different name on migraine were called hemicrania(頭偏痛, 邊頭痛, 偏頭風). 2. In the cause of a disease in migraine, the cases were clasified into the fallowing kind : internal cause were a decline in energy and blood(氣血具虛), external cause were outside evil(外邪) in wind cold heat wetness(風寒暑濕), non internal, external cause were exhaustion. The right side migraine were concerned phlegm heat, the right side migraine were concerned wind decline in blood. 3. Migraine is appeared on the side, For the reason, liver function in excess of normal limits(肝陽上亢), a sudden of liver fire(肝火) is becomeed of invasion upon soyangkuong(少陽經) in internal external cause 4. Usage method of medicines is appeared that order underclothes theraphy(內服法), to pump out in nose theraphy, to join head theraphy(頭點法), heating smoke theraphy(熏煙法) 5. CNIDII RHIZOMA(川芎) is in mostly general use for migraine, in that order LEDEBOURIELLAE RADIX(防風) ANGELICAE DAHURICAE RADIX(白芷) ASARI HERBA CUM RADICE(細辛) NOTOPTERYGII RHIZOMA(羌活) GLYCYRRHIZAE RADIX(甘草) CHRYSANTHEMI FLOS(菊花) BUPLEURI RADIX(柴胡) SCUTELLARIAE RADIX(黃芩) ANGELICAE GIGANTIS RADIX(當歸) GYPSUM FIBROSUM(石膏) MENTHAE HERBA(薄荷) GLYCYRRHIZAE RADIX(炙甘草) VITICIS FRUCTUS(蔓荊子), nature is in mostly general hot warm(辛溫), bitter cold(苦寒), guikuong(歸經) is in mostly general liver gall kuong(肝膽經), efficacy is in mostly general to remove wind pain (祛風止痛) and to down fire(瀉火).

Recently, with the growth of software for electromagnetic-thermal analysis, it has been studied that the precise analysis and investigation for cause of the electrical fire using computer simulation is on the basis of theroy for electromagnetic-thermal analysis. But it is very lacking for the precise analysis and investigation of cause for the electrical fire. In this paper, we have simulated the temperature distribution of wire to current and the force between the two conductors according to the current and the distance of the vinyl flat-type electrical wire(600 V, VFF, $2C{\times}$1.25mm^2) using the finite element method(Flux2D) in a overcurrent. And we will present the cause analysis method of electrical fire by experiment for distance between the two conductors according to current and time using large current supply device(Model: EHT_EFAD, Korea) in a overcurrent.

In this research paper, the analysis, and improvement, of conditions of fire investigation related to products were derived. The results of the research showed that the main entity that plays the role of coordinator on the scene of fire investigation is unclear, systematic devices to protect the rights and interests of fire victims are inadequate, there are limitations in deriving the cause of fire due to the lack of fire appraisal organizations in fire departments, and the product companies are passive in their initial actions. As for improvement measures, it was found that the adoption of the system in which fire departments can play the role of mediator on the scene of fire investigation, the establishment and operation of fire appraisal organizations and research institutes in fire departments, and the establishment of network between fire departments and product companies are needed.

Building become higher. larger and more complex than ever before, showing abrupt changes in building structures. forms and mechanical systems. Likewise hazads of fire and the scale of fire losses become more and more greater. Therefore. considerations for fire safety take up great portion of the building design process. In this study, problems of high-rise building fires and basic directions for fire safety of high-rise building design were studied through the statistical analysis of 138 fire cases. The results of this study are summarized as follows : ·Most of the fires in high-rise building occur on the low floors and the fire frequencies are very low on the upper floors. Fire casualties are liable to be more on the upper floors than on tile floor of fire origin. ·The important causes of evacuation failures were analyzed as being late in escape and lack of stairwell enclosures. ·The main cause of vertical fire spread is lack of stairwell enclosures. However, the fire spreads mainly through the enterior windows in apartment houses. The combustible materials in buildings act on as the major factors of horizontal fire spread and the improper fire doors play role of another the critical causes. ·The basic directions for fire safety of high-rise building design put much stress firstly on the compartmentation of the buildings effectively performing the provision of safe escape routes and the safe refuse places in buildings.

Recently, South Korea is reaching aged society through ageing society. Accordingly, facility related to aged is increased consistently because of effort to improve the welfare of the elderly through elderly long term care insurance in 2008. however, the number of fires in the elderly facilities is increasing rapidly too. It is becoming bigger and higher and the characteristics of person who is unable to afford are mostly having difficult evacuation. so fire safety guildelines are urgently needed but korea research is insufficient. In this study, we propose a fire scenario through investigation of fire causes for fire safety guideline development of elderly facility, and describe to the fire safety countermeasure.

This study analyzed ignition probability about Lithium-polymer batteries of what variously were being produced wearable devices recently. The study analyzed ignition probability by PCM(Protection Circuit Module) operating state and overcharged, over-discharged, exposed to high temperatures of Lithium polymer batteries, analyzing wearable devices on the market. Then it classified experimental results to implement analysis comparison about weight, X-ray imaging, battery decomposition. With these experiments, the study analyzed combustion-possibility and fire patterns. These statistics will be used to measure and verify the cause of a fire when identify wearable devices using Lithium-polymer batteries.

Detection of fire accelerants from fire residues is critical to determine whether the case was arson or accidental fire. However, to develop a standardized model for determining the presence or absence of fire accelerants was not easy because of high temperature which cause disappearance or combustion of components of fire accelerants. In this study, logistic regression, random forest, and support vector machine models were trained and evaluated from a total of 728 GC-MS analysis data obtained from actual fire residues. Mean classification accuracies of the three models were 63 %, 81 %, and 84 %, respectively, and in particular, mean AU-PR values of the three models were evaluated as 0.68, 0.86, and 0.86, respectively, showing fine performances of random forest and support vector machine models.

Concrete undergoes a series of thermo-based physio-chemical changes once exposed to elevated temperatures. Such changes adversely alter the composition of concrete and oftentimes lead to fire-induced explosive spalling. Spalling is a multidimensional, complex and most of all sophisticated phenomenon with the potential to cause significant damage to fire-exposed concrete structures. Despite past and recent research efforts, we continue to be short of a systematic methodology that is able of accurately assessing the tendency of concrete to spall under fire conditions. In order to bridge this knowledge gap, this study explores integrating novel artificial intelligence (AI) techniques; namely, artificial neural network (ANN), adaptive neuro-fuzzy inference system (ANFIS) and genetic algorithm (GA), together with traditional statistical analysis (multilinear regression (MLR)), to arrive at state-of-the-art procedures to predict occurrence of fire-induced spalling. Through a comprehensive datadriven examination of actual fire tests, this study demonstrates that AI techniques provide attractive tools capable of predicting fire-induced spalling phenomenon with high precision.
