The result of Bibliographic studies on the pathological mechanism of the sudden coma, we got the conclusion like this. 1. The sudden coma is an acute syndrome that refers to be a sudden fainting, an unconsciousness, an aphasia or a cold clammy limb, and immediately awakes or dies, and awakes in a short time, and if we awake, it doesn't leave over and above a sequela. 2. The clinical presentation of the sudden coma can be summarized as follows : The 1st is a disease raising the sudden death due to unconsciousness accompanied by wry mouth & sudden syncope with coma. The 2nd is simply the state of cold limbs. The 3rd is the meaning of the physique and symptomes of the six meridians. The last is the ancient method of expression in contrast of the beriberi. 3. The pathological mechanism of the sudden coma consists of the toxoid from outside, Qi and Xie, fatigue, damp phegm, the damage from seven emotions and the damage from five mental elements, especially the mental disorder due to the angry energy, causes the problems when the fleming-up of liver fire and the depressed of liver qi raise the physiological disorder. 4. Therapeutic methods of sudden coma are soothing the liver and remove stasis, soothing depression and circulating of the qi, calming the liver and suppressing yang. When that is early stage, at first, we must checking upward adverse flow of the qi after promoting the circulation of qi and awakening, and then, we must regulate excessive deficiency of yin yang by therapy that is based on differentiated in symptoms according to heat & cold, deficiency & excess, and use invigorating herb medicine for supporting vigour.

This paper is about the emotional factors in Chiljeongsang(七情傷). To specify the collective term into specific categories, an examination of the meaning of emotion of the East and West was primarily undertaken. The importance of emotion lies in the fact that it provides a link between the individual and the outside world. Emotion was perceived as reflections of the human nature and mental activity by philosophers and psychiatrists throughout history. In the views of psychologists, the focus was on not emotion itself, but rather the emotional experience in human, and its psychological and physiological mechanism. In Traditional Medicine, problematic emotion is called Chiljeong(七情). The term Chiljeongsang(七情傷), which is a compound word of 'Chiljeong(七情)' and 'Sang(傷)' meaning 'damage', is used in referring to illness related to unhealthy emotions. It is used to describe illness caused by Chiljeong(七情) and mental disorders that result in emotional symptoms. It also refers to illness where Chiljeong(七情) plays a role in creating a more direct cause of illness in the larger pathogenic process. In the contents of Chiljeongsang(七情傷) in Traditional Medicine, emotion as causation of Gi(氣) disorder could be found the most, while explanation on the psychological process related to the creation of Chiljeong(七情) was insufficient. This tendency is related to the philosophical basis of Traditional Medicine. Out of the two patterns suggested, the mind-based Chiljeongsang(七情傷) pattern includes the psychological aspects of damage, in which key focus is on the cause that arouses problematic emotion, its process and the meaning this emotion entails. To explain this, concepts from psychiatry, especially Jung's theory on neurosis was adopted. In treating a Chiljeongsang(七情傷) patient, mere knowledge of the physiological changes of the body in terms of Gi(氣) is insufficient. This is because mental factors play a large role in Chiljeongsang(七情傷), and the more a condition is 'mental', the more complex it becomes and the more it influences life as whole. Therefore, the doctor must approach the patient with not only medical knowledge, but also overall knowledge on all aspects of human life.

Gastric mucosal damage by iron pills is often reported. However, iron pill aspiration is uncommon. Oxidation of the impacted iron pill causes bronchial mucosal damage that progresses to chronic bronchial inflammation, necrosis, endobronchial stenosis and rarely, perforation. We reported a case of a 92-year-old woman with chronic productive cough and significant left-sided atelectasis. Bronchoscopy revealed substantial luminal narrowing with exudative inflammation of the left main bronchus. Bronchial washing cytology showed necroinflammatory exudate and a small amount of brown material. Mucosal biopsy showed diffuse brown pigments indicative of ferrous pigments, crystal deposition, and marked tissue degeneration. After vigorous coughing, she expectorated dark sediments and her symptoms and radiological abnormalities improved. There are a few such reports worldwide; however, this was the first case reported in Korea. Careful observation of aspiration-prone patients and early detection of iron pill aspiration may prevent iron pill-induced bronchial injury.

The effect of methanol extract from Agaricus blazei Murill on the hepatotoxicity was investigated $CCl_4$ is one of the oldest and most widely used toxins for the induction of hepatic damages and fibrosis in experimental animals. In this study, male Sprague-Dawley(SD) rats were randomly divided into 6 groups of the control(C), $CCl_4(T),\;CCl_4$ and high fat group(TL) with matching sub-groups of Agaricus blazei Murill extract-fed groups of CA, TA and TLA. Methanol extracts of Agaricus blazei Murill were fed 50 mg/kg B.W daily via drinking water. A 1.2 mL of $CCl_4/kg$ body weight was administered by oral intubation twice a week for total of six times. The levels of total-cholesterol, TG, LDL and LDL-phospholipids were elevated by $CCl_4$ treatment as compared to the control(C). However, Agaricus blazei Murill methanol extract feeding in the group of TA and TLA significantly(p<0.05) decreased TG by 53.1 % and 17.9% compared to the internal control of T and TL, respectively. Triglyceride of TL was increased by 3.33 times(p<0.05) compared to the control(C) with $CCl_4$ and high fat administration from 3.78 mg/g to 12.60 mg/g liver. The extract(CA) also reduced kidney weight compared to the control(C). With the administration of high fat and $CCl_4$(TLA), the extract reduced the organ weight of both liver and kidney and further, significantly reduced TG, total cholesterol and GTP activity. Hepatoprotective effects of Agaricus blazei Murill on GOT, GPT, AP and LDH activities were enhanced by the extract feeding. Electronmicrograph showed that $CCl_4$ deteriorated the structure of cytoplasmic matrix with its uneven distribution. However, the extract reconstituted the damaged cytoplasm and stimulated mitochondriogenesis. The above results suggest that Agaricus blazei Murill may have a possible protective effect against chemically induced liver damage and further help to reduce the symptoms of fatty liver.

On November 15, 2017, a unpredictable liquefaction damage was occurred at the $M_L=5.4$ Pohang earthquake and after, many researches have been conducted in Korea. In Korea, where there were no cases of earthquake damage, it has been extremely neglectable in preparing earthquake risk maps and building earthquake systems that corresponded to prevention and preparation. Since it is almost impossible to observe signs and symptoms of drought, floods, and typhoons in advance, it is very effective to predict the impacts and magnitudes of seismic events. In this study, 14,040 borehole data were collected in the metropolitan area and liquefaction evaluation was performed using the amplification factor. Based on this data, liquefaction hazard maps were prepared for ground accelerations of 0.06 g, 0.14 g, 0.22 g, and 0.30 g, including 200years return period to 4,800years return period. Also, the correlation analysis between the earthquake acceleration and LPI was carried out to draw a real-time predictable liquefaction hazard map. As a result, 707 correlation equations in every cells in GIS map were proposed. Finally, the simulation for liquefaction risk mapping against artificial earthquake was performed in the metropolitan area using the proposed correlation equations.

Background: Lung injuries due to exposure to humidifier disinfectants (HDs) were reported in 2011 in South Korea. As a result of the government's epidemiological investigation and toxicity test study, it was found that HDs caused health damage such as lung disease. Objectives: The purpose of this study was to classify HD exposure ratings and analyze the affecting factors that could identify the relationship with lung disease. Methods: Exposure assessment for HDs was conducted using a questionnaire during face-to-face interviews with the applicants. Ratings of high exposure (Class 1) and low exposure (Class 2) were cross-tabulated with clinical ratings (acceptable and unacceptable). Logistic regression analysis was carried out by setting the clinical rating of lung disease as a dependent variable and the socio-demographic and exposure characteristics obtained through the questionnaire as independent variables. Results: The concentration in air of polyhexamethylene guanidine (PHMG) was 71.96±107.47 ㎍/m³, and the exposure concentration was 15.21±23.28 ㎍/m³ . The exposure rating was overestimated with 97.1% of affected subjects having high exposure using margin of exposure (MOE), but only 9.9% matching the clinical class. In the overestimated group, it could be explained by the fact that the exposure time was long and the subjects had already recovered from damage symptoms. As a result of logistic regression analysis, ten variables were found to be significant influencing factors. Conclusions: A new exposure rating could be calculated based on the MOE, and factors affecting lung disease could be estimated through comparative evaluation with the clinical rating.

The hydrogen fluoride gas generated from making the cement hardener injured the plants growing at the neighbour field. This investigation was conducted on sample analysis of hydrogen fluoride gas damage plants which included the ratios of destroyed leaves, damage symptoms, and nutrient elements in paddy rice and weeds. The results obtained were as follows; 1) The ratio of destroyed leaves at near HF source was very high reaching about 95% at 100m, 65% at 500m, 5% at 2㎞, respectively. 2) The necrosis was the characteristic symptom of fluoride injury on rice plant and occurred predominantly at the tip and margins of damage leaf. It developed along the tip and margins of leaves with a dull, gray-green, water soaked discoloration. 3) The fluorine content of tip and margins of damaged rice leaves were 1,600 ppm, 3 to 20 times higher than that of center part and it ranged from 130 to 242.5 ppm in weed leaves, but from 10 to 15 ppm in normal weed leaves. 4) The contents of calcium, potassium, silicon, iron and manganese were higher in tip and margins than in the center of rice damage leaves. 5) The Cocculus trilolous. D.C was the most resistant plant to HF gas than any other plant growing in this site, while wild berry and aralia tree belong to most sensitive plant group.

To develop transgenic orchardgrass (Dactylis glomerata L.) resistant to high temperature, the recombinant DgHSP17.2 gene was introduced into orchardgrass plants using the Agrobacterium-mediated transformation method and expressed constitutively under the control of the CaMV 35S promoter. The results of genomic DNA PCR and Southern analysis showed a DNA band and hybridization signal on agarose gel and X-ray film in transgenic orchardgrass plants harboring the recombinant DgHSP17.2 gene, but a DNA band and hybridization signal were not observed in the wild type and empty vector control plants. The same result was also obtained in RT-PCR and Southern blot analysis, and these transgenic orchardgrass plants did not show any morphological aberration both in the culture bottle and soil mixture. When leaf discs cut from transgenic orchardgrass plants with recombinant DgHsp17.2 gene were exposed to lethal temperature (heat treatment at $60^{\circ}C$ for 50 min), 60-80% of the leaf discs showed only damage symptoms, but non-transgenic leaf discs showed a lethal condition. These results indicate that the DgHsp17.2 gene may act as a protector from heat stress in plants.
