In the literatual studies on the causes and treatments of the melasma, the results were as follows. 1. Melasma is the blackish patch on the face, is belong to the cartegory of the 'Myunjin(面塵)', 'Myunganzung(면간증)', 'Jakban(雀斑)' etc. in Oriental medicine 2. Melasma is deeply associated with Yangming channel in Meridian, with the spleen, stomach, heart and kidney in Viscera. 3. The pathogenic factors of Melasma is divided five parts. One is insufficient of Yangming's energy in Neijing(內經). Two is incoordination between vital energy and blood caused by wind-evil and phlegm-retention syndrome. Three is anxiety impairing the spleen. Four is kidney-asthenia and fire-hyperactivity. Five is heat-evil. 4. In the treatments of Melasma, Sthenia-syndrome was used cooling blood and activating blood circulation, or dispelling wind-evil and promoting meridian, or expelling fire-evil and removing toxic material etc. Asthenia-syndrome was used invigorating the liver and kidney, or nourishing yin and keeping fire downwards etc. 5. Melasma is concerned with sun-light, is mostly seen in female. 6. In the prescription of Melasma, it was used Jujesamultang(酒製四物湯加減), Okyong -san(玉容散), Chunghwasungitang(沖和順氣湯), Okyongseosisan(玉容西施散), Yukmiji-hwanghwan(六味地黃丸) etc.

The purpose of this study is to distinguish the causes of broken glass on doors or windows when it is originally kept among the remains on the floor in fire site - whether it was broken due to heating or outer power-through test and characteristics of the broken plane including the pattern on the plane. Addition to it, the study tries to find characteristics to judge the point and direction of breakdown through the analysis of glass broken by outer power. With two assumed causes - a) breakdown due to heating and b) breakdown due to outer power-3 pieces of glass plates ($30cm{\times}30cm{\times}5mm$) were tested for each case, getting the results as following: First, for the glass broken due to the change of temperature, the broken plane is of slow and smooth curve without any pattern. Second, for the glass broken due to outer power, with the impact point as the center, the glass shows breakdown of radial type and the side shows breakdown of near-perpendicular type. The far the broken piece is from the impact point, the bigger the size is. The broken piece at the impact point is of long triangle type and the two long planes of the triangle shows semi-arc with the center of breakdown point and the other plane shows opposite pattern. Third, when glass that is damaged by outer power is heated, damaged forms and side patterns of the glass that is damaged by outer power are heated and disappeared.

Coal samples with different joints morphology were subjected to uniaxial compression experiments, cracks evolution was recorded by Nikon D5300 and acoustic emission (AE) energy signals were collected by AEwin Test for Express-8.0. During loading process, coal samples deformed elastically with no obvious cracks changes, then they expanded gradually along the trace of the original cracks, accompanied by the formation of secondary cracks, and eventually produced a large-scale fracture. It was more interesting that the failure mode of samples were all shear shape, whatever the original cracks morphology was. With cracks and damage evolution, AE energy radiated regularly. At the early loading stage, micro damage and small scale fracture events only induced a few AE events with less energy, while large scale fracture leaded to a number of AE events with more energy at the later stage. Based on the multifractal theory, the multifractal spectrum could explain AE energy signals frequency responses and the causes of AE events with load. Multifractal spectrum width (${\Delta}{\alpha}$), could reflect the differences between the large and small AE energy signals. And another parameter (${\Delta}f$) could reflect the relationship between the frequency of the least and greatest signals in the AE energy time series. This research is helpful for us to understand cracks evolution and AE energy signals causes.

The writer reviewed on Chojop and came to conclusions as follows. Symptoms of Chojop is appeared digestive ailment such as belching, nausea, regurgitation of acid, stomachache etc., if being serious, felt oppressed with palpitating in chest and uneasiness at times. In Dangaesimbub written by Chujinhyung, the causes of Chojop were mainly regarded as phlegmatic fire(痰火) and suggested the way of treatment. The causes of Chojop are movable fire with phlegm, insufficiency of blood caused by thinking to excess, and Shinyanghohan(腎陽虛汗) that is piled cold phlegm by voidance and coldness of Renal Yang, but the main cause is brought to a conclusion as phlegmatic fire. The phlegmatic fire is come from being in discord with the spleen and the stomach, or from in harmony between vigor and blood according to essence and vital energy which are disturbed by combined feelings. That is caused by disharmony between inner and outer conditions according to individuals. The distinctive features in shapes of Chojop are revealed to shapes such as manlike woman, womanlike man, wearing darkish or reddish color between two eyebrows, being almond eyed, strong eyebrows, being sunk the upper part of the nose bridge, lots of facial blots, Dam-body, Ki type, Shin type, Birds group, and Yangmyung type. The doctors can prescribe Whadamchungwhatang to Yangmyung type, Yanghyulsamul-tang for patients with strong eyebrows so flourishing blood and vigor, Hyangsapyungwuisan for patients belong to Birds group, Soshikchungul-tang for Ki type, and Palmiwhan for man belonged to Bangkwang-body with voidance and coldness of Renal Yang chiefly.

After studying the cause and mechanism of the itching with the perspective of chronic medical books including Neijing, and the annotators, the conclusions are as follows. 1. The itching, which has correlation with the heart, is the deficiency symptom(虛症). It is generated when the lung-metal(肺金) is infected by the fire pathogen(火邪) and developed to depression(鬱), because of the heart fire flaming upward of circuit year(歲火太過). The treatment is to make metal depression scatter(金鬱泄之). 2. The itching occurs between the dermis(膚) and the epidermis(皮). 3. The itching generates when the excess of yang exuberance(熱盛極) precede the transmission of the wind-heats(風熱), the wind-cold(風寒), and the wind-dampness(風濕). It causes the blood deficiency(血虛) and the blood stasis(血瘀) because of the skin dryness. 4. The itching usually generates during summer, causes the body fever(身熱) and the dermis pain(膚痛). When it becomes worse, it causes generalized itching and vesicles at the whole body(浸淫). 5. The itching is related to the spirit(魄), which works in unconsciousness and the movement of defense qi(衛氣) in night.

Recently, rural housing in urban areas has been increasing due to the improvement of income level. With the increase of the construction of the power house, the installation of the heating system using the harmonious fuel for the purpose of heating and the beauty of the room is increasing rapidly. In addition to the increasing use of firewood heating equipment, the incidence of fire is also increasing. Analysis of the National Fire Data System of the Fire Department The result of the analysis of the National Fire Data System Many parts of the fire are incinerated by the accumulation of tar due to the incompleteness of periodic cleaning inside the cylinder. The distance between the fire extinguisher and the combustible materials such as ceiling, Resulting in fire. In addition, it was found that much of the fire of the firewood heating system in the time zone occurs during the sleeping and resting time and there is not enough time for the residents to cope. This, in turn, causes serious harm to the lives and property of the users of the pyrotechnic heating system. Therefore, in this study, domestic and foreign standards and laws related to fuel oil heating facilities were analyzed and 12 cases of fire accidents were analyzed. Through the revision of the fire prevention and firefighting facilities installation and maintenance law, the installation standards of the alarm and fire extinguishing facilities were presented.

Over the last 100 years since the introduction of electricity, the nation has faced ever increasing demand for electricity as consequence of the rapid economic growth. The expanded consumption ratio for electricity naturally increased the possibility for electricity related accident mainly iii the form of electrically ignited fire and human injuries from electric shock. Under such circumstances, the presented study sets a focus on analysing the causes of the electrically related fire accidents happened in the nation over the last 10 years(in the 80's) to provide a scientific basis for identifying the cause of electric fires. Identification of the cause of fire ignited electrically may be approached either by studying accident related electrical properties or by investigating power instruments at the place of the accient. In the present paper, the former approach is taken especially on investigating the consequences of over current induced by short circuiting of high power instruments which is reported as the primary cause electricity related fire accidents. In order to provide reliability of the identification method, microscopic photograph's are taken for the cross sections of the electrical materials(fuse, wire, plug socket and plug) after being exposed to over current and heated by external means respectively. The results are consequently compared and analysed.

In this study, the purpose was to consider the conception, the causes, the pathology, the treatment and the prescription of 'Zhong Feng(中風)' through Liu Wan-Su's works. The results are obtained as fallows. First, Liu Wan-Su regarded Zhong Feng(中風) as 'Feng Re(風熱)'. He thought the causes and the pathology of Zhong Feng(中風) that pathologically fever was due to excess of feelings and 'Heart-fire(心火)', was due to intemperate living, so he thought the leading causes of Zhong Feng(中風) were Feng Re(風熱) and Heart-fire(心火) and emphasized the internal causes of Zhong Feng(中風). But he excluded absolutely external causes. He also insisted that Feng Re(風熱) was cause in a fat and a thin person. Second, according to symptom of the limbs and 'Jiu Qiao(九竅)', he classified Zhong Feng(中風) into 'Zhong Fu(中腑)' and 'Zhong Zang(中臟)'. And in the treatment of Zhong Feng(中風), the three principle was set up that 'Sweating .method(發表法)' in the case of Zhong Fu(中腑), 'Passing method(通滯法)' in Zhong Zang(中臟) and 'Nutrient method(養筋法)', in case that both symptom would not revealed. And in the prescription of Zhong Feng(中風), he presented 'Xumingtang(續命湯)', 'Sanhuatang(三化湯)' and 'Daqinfantang(大秦?湯)' to them each.

This paper aims at the development of an knowledge base for an electrical fire cause diagnosis system using the entity relation database. The relation database which provides a very simple but powerful way of representing data is widely used. The system focused on database construction and cause diagnosis can diagnose the causes of electrical fires easily and efficiently. In order to store and access to the information concerned with electrical fires, the key index items which identify electrical fires uniquely are derived out. The knowledge base consists of a case base which contains information from the past fires and a rule base with rules from expertise. To implement the knowledge base, Access 2000, one of DB development tools under windows environment and Visual Basic 6.0 are used as a DB building tool. For the reasoning technique, a mixed reasoning approach of a case based inference and a rule based inference has been adopted. Knowledge-based reasoning could present the cause of a newly occurred fire to be diagnosed by searching the knowledge base for reasonable matching. The knowledge-based database has not only searching functions with multiple attributes by using the collected various information(such as fire evidence, structure, and weather of a fire scene), but also more improved diagnosis functions which can be easily wed for the electrical fire cause diagnosis system.
