  • The extreme weather conditions become frequent and severe with global warming. To prevent and cope forest disaster like a forest fire, we need an accurate micrometeorological prediction system for mountainous regions. This study addressed the forest fires occurred at Bonghwa and Gangneung in March, 2013. We constructed and optimized the prediction system that were required to interpret and simulate the forest micrometeorology. At first, we examined WRF physical sensitivity. Subsequently, KMA AWS observation data were assimilated using three-dimensional variation data assimilation method. The effectiveness of the assimilation was examined by using AWS observations enhanced with the Forest Research Institute observations. Finally, The 100 meters spatial resolution wind data were obtained by using the MUKLIMO for the given wind vector from WRF.

  • Systemic Lupus Erythematosus(SLE) is an autoimmune disease invading the skin, joint, kidney, intestinal membrane, neurosystem and other organs. SLE is an autoimmune disease characterized by immune dysregulation resulting in the production of antinuclear antibodies(ANA), generation of circulating immune complexes, and activation of the complement system. In Korean medicine, lupus can be classified as acute arthritis, reddish butterfly erythema, asthenic disease, edema and so on. The cause and procedure of the diseases are flourishing noxious heat, excessive fire due to deficiency of yin, blood stasis due to stagnation of qi, internal movement of the liver-wind, congenital deficiency, exhausted vital-qi, which are treated by clearing away heat and cooling the blood, nourshing yin and extinguishing fire, treating flatulence and activating blood circulation, nourishing the blood to expel wind, invigorating the liver and kidney, invigorating qi and replenishing the blood. To experimentally examine the influence of Insam-Buja-Tang (Ginseng & Aconiti Extract, IBT) on the outbreak and development of lupus, lupus induce MRL/MpJ-Faslpr lupus-prone mice model was used. As IBT was orally administrated to a lupus model mouse, various tests such as the weight, urine protein, renal function, Lymph cell test of the spleen, Cytokine expression, histopathological analysis of kideny were performed to see the influence on the kidney and whether it work effectively on the immune function. The main purpose of this study is to evaluate the effect of IBT on MRL/MpJ-Faslpr lupus-prone mice model. The effect of IBT on MRL/MpJ-Faslpr lupus-prone mice that can have autoimmune disease similar to SLE in human was evaluated after IBT per oral in the present study.

  • The "Somun Jogyongron(素問 調經論)" describes excess and deficiency syndromes. The study suggests that excess syndrome(實證) is caused by vigorous pathogenic fire(火邪)(the spirit(神)), pathogenic dryness(燥邪)(Gi(氣)), pathogenic wind(風邪)(blood(血)), pathogenic dampness(濕邪)(physique(形)) or pathogenic coldness(寒邪)(will(志)). When pathogenic fire is dominant within the body, Gi and blood becomes excessive and come out of the body, but the body cannot take them back, leading to the symptom in which the patient cannot stop laughing. When pathogenic dryness prevails, the lung(肺) cannot function properly. This means that the convergence(收斂) function of the clearing the lung and descending Gi(肅降) is deteriorated, and the patient shows symptoms of dyspnea and cough. Strong pathogenic wind increases the ascencling Gi in the liver(肝氣) and fuel angry emotion when the patient becomes upset. When pathogenic dampness is dominant, spleen(脾) function drops due to lumping effects, and the patient will experience abdominal distention(腹脹), which will disturb urination and defecation. When pathogenic coldness prevails, abdominal distention occurs due to condensating effects, and Yang Gj(陽氣) in the kidney(腎) is disturbed, leading to digestion disorders and eventually water-grain dysentery. Deficiency syndrome is caused by the lack of essential Gi(精氣) in the five viscera(五藏). Deficiency of sprit means the lack of Gi in the heart(心氣), so the patient becomes vulnerable to sadness. Deficiency of Gi means the lack of Gi in the lung(肺氣), so the patient may have breathing disorders. Deficiency of blood means the lack of Gi in the Liver(肝氣), so the patient can be easily scared. Deficiency of physique means the lack of Gi in the spleen(脾氣), making it difficult to use arms and legs. Deficiency of will means the lack of Gi in the kidney(腎氣), so Gowl syndrome(厥證) can ensue.

  • Objectives : This paper examined the Buddhist contents within the text, Bencaoshengyabanji(本草乘雅半偈). Methods : Medicinals that were searched through Buddhist vocabulary were examined. Results & Conclusions : Medicinals that quoted the Lengyanjing were related to the Water-Fire interaction, food and medicine, and karma, while those that quoted the Shidian were related to 無上道, 去惡殺蟲, 樞機滑利, and 生生之氣. Those related to the Great Earth of the Four Elements corrected the body's form based on Metal Qi, while those related to the Great Water were connected to the circulation of water dampness. Those related to the Great Fire were deeply related to Yang Qi, and those related to the Great Wind were connected to Wind control. Of the Four Origins, medicinals that were viviparous lowered Qi, while those that were oviparous were related to communicating Shen, treating diseases of the Conception Vessel, and the closing and opening of day and night. Medicinals originating from dampness were related to urination and fluid management, while those of metamorphosis were related to the process of Qi. Those related to emptiness were related to the communication of the Qi system, while those related to 六根六塵 were connected to calming the Shen and strengthening the will, and smoothing the nine orifices. Medicinals related to 圓通 were used for improving eyesight and hearing and controlling the closing and opening. Lu Zhi-yi's analysis of medicinals through the Lengyanjing is original in that it suggested a new perspective other than previous theories on pharmacology which were based on the Yin-Yang and Five Phases and Rising/Lowering/Floating/Sinking theories, but also pedantic and exaggerated. The Bencaoshengyabanji is a unique text on medicinals which analyzed each medicinal under Buddhist influence. However, it also followed the contexts of other previous texts on medicinals, and influenced Zou shu.

  • The causes and treatment of alopecia are concluded based on the records found successive oriental medicine in order to persuade new treatments for alopecia as following : 1. In the context of modern medical science male-dominated alopecia was referred as dok-rak(禿落), cho-dok(早禿), chon-dok(全禿), pal-ju-tal-bal, chu-bal-sun and pal-sun(髮癬) alternatively, while alopecia areata was refereed as yu-pung(油風), pan-dok(斑禿), kwi-ji-du and kwi-che-du(鬼剃頭). 2. The causes of alopecia is related with condition of Gi(vital energy) and Hyul(blood) in the twelve channels, such as weakening of vital energy in the conduits, condition of internal organs as heat in the lung, weak kidney or liver vitality, and eating habits such as severe ingestion of bitter taste or sweet taste food. Other distinct reasons are penetration of wind and dryness into a head due to weakening Gi and Hyul inside human body, flaring up of the asthenic fire due to excessive eatings, hard labour or psychological sufferings deficiency of blood, deficiency of vital essence of kidney, phlegm caused by dampness and heat, and stagnated blood. 3. According to demonstration of alopecia, the causes of alopecia areata are listed as internal wind due to heat of blood, deficiency of liver and kidney, blookage of channels and collaterals by stagnated blood, and causes of male-dominated alopecia are listed as wind dryness caused by heat of blood, dampness and heat, and heat, wind and dryness due to deficiency of blood.

  • The purpose of this study is to investigate ways to control the wind dispersal of contton-wrapped seeds of such poplars and willows as Poplus alba, P. tomentiglandulosa, P. euramericana, P. deltoides, and Salix pseudo-lasiogyne. These trees are hated by many people because of their seeds blowing all over the place during May. These cottony seeds can be nuisance to various types of outdoor activities, pose safely threat to drivers, become fire hazards during prolonged spring dry spells, and cause many types of health hazards of allergy such as sneezing. rhinitis, asthma, and skin rashes. Four control methods can be used to resolve the problem. First, pruning can be a solution, but it is unsatisfactory in terms of costs and outcome. Second, planting of male trees only can be a solution, but it is hard to identify sexes of saplings. Third, female trees can he replaced with other species. But it requires high costs and takes at least ten years to functionally replace the removed ones. As an alternative to such unsatisfactory control methods, the possibility of applying plant growth regulators has been investigated since 1983. During the pre-test, various concentrations and mixtures of them were either sprayed or injected, but failed to achieve any promising results. But the injection of a mixture made up of 0.75g of 2-chloroethane phosphonic acid with 0.2 mg of GA in 300cc water in the end of March produced premature falling of almost all aments and capsules of treated poplars and willows. It was found that the effect of the injection lasts two years. The results of the main experiment of 1987 can be summarized as follows ; First, the injection of the mixture of 2-chloroethane phosphonic acid and GA increases the premature abscisin of aments and capsules, thus reducing the wind dispersal of the cottony seeds of S. pseudolasiogyne, P. tomentiglandulosa, and P. euramericana 1644.09, 1200.61, and 1485.11 times, respectively, than that of the naural abscisin, It is estimated that the average number of wind-blown seeds reduced are approximatively 6,185,100, 4062,900, and 2,830,670 per tree, respectively. Second, the treatment causes no observable side effects on the growth of the samples tested.

  • With climate change and the global population growth, the frequency and scope of wildfires are constantly increasing, which threatened people's lives and property. For example, according to California Department of Forestry and Fire Protection, in 2020, a total of 9,917 incidents related to wildfires were reported in California, with an estimated burned area of 4,257,863 acres, resulting in 33 fatalities and 10,488 structures damaged or destroyed. At the same time, the ongoing development of technology provides new tools to simulate and analyze the spread of wildfires. How to use new technology to reduce the losses caused by wildfire is an important research topic. A potentially feasible strategy is to simulate and analyze the spread of wildfires through computing technology to explore the impact of different factors (such as weather, terrain, etc.) on the spread of wildfires, figure out how to take preemptive/responsive measures to minimize potential losses caused by wildfires, and as a result achieve better management support of wildfires. In preparation for pursuing these goals, the authors used a powerful computing framework, Spark, developed by the Commonwealth Scientific and Industrial Research Organization (CSIRO), to study the effects of different weather factors (wind speed, wind direction, air temperature, and relative humidity) on the spread of wildfires. The test results showed that wind is a key factor in determining the spread of wildfires. A stable weather condition (stable wind and air conditions) is beneficial to limit the spread of wildfires. Joint consideration of weather factors and environmental obstacles can help limit the threat of wildfires.

  • The comparison of climate's character of Yunqi(運氣) with the data of meterological observation were made in the research of climate. 1. The comparison of the average velocity of wind, temperature, rainfall, humidity of Seoul, by late 1954 to 1983, with Yunqi(運氣) was made. Fire-Chi(火氣) and moisture-qi(濕氣) were matched with the attribute of Taiyun(大運). Cold-qi(寒氣) was had some relationship. Dry-qi(燥 氣) and Wind-qi(風氣) were not matched. About the relationship of Spirit-of-official-sky(司天之氣) with climate, when the Moisture-soil(濕土) was added, they were matched and when the King-fire(君火) was added, they have some relationship. But Wind-tree(風木), Dry-metal(燥金), Buble-fire(相火), Cold-water(寒水) was added they were not matched. 2. According to the observation data of rainfall by late 180 years of Seoul; about Taiyun(大運), when the Water-Yun(水運) was greatly exceeded and Fire-Yun(火運) was shorted, in the case of Official-sky(司天), when Wind-Tree(風木) was added, the frequency was highly. So when the Soil-Yun(土運) was greatly exceeded and when Official-sky(司天)was added to the Moisture-soil(濕土), the rainfall was not matched. 3. The relationship of the frequency of the abnormal climate occurrences between Yunqi-promotion-weak(運氣盛衰)and Yunqi-Harmony(運氣同化) and Yunqi-soft-attacking(運氣順逆) in the weather of Korean Peninsula was compared by 1564 to 1863. They were not matched except the case of Yunqi-Harmony(運氣同化). 4. There were some cases which were not matched exactly between the climate predicted by the theory and real climate in 1984, the year of Kap-ga(甲子年). But many correspondence between the observation by the office of meteorology and the prediction by the analysis from Yun-qi-sang-hab(運氣相合) theory. 5. Because meterological phenomena of real world and analysis from the hypothesis of Yunqi(運氣) have no relationship with each other, some of Doctor denied Yunqi(運氣) in the way of matching mechanically. But the thought of Doctor who denied Fortune-spirit(運氣) made promotion for the theory of divination by bringing deeper insight. And it was not only the negative side. 6. In the point of geographical difference, the climate of China, the origination Yunqi theory, is different from the Korea's. Thus some observation errors should be considered. From the basis of this thesis, I hope that the deeper advance would be made into the Korean Yunqi theory.

  • This study analyzed recent cases of ship fires explosions and investigated their problems and coping plans. Through analysis on the statistical figures, it was found that our nation's situations of maritime accidents by kind during the period of 2009~2013 showed the ratios of ship accidents caused by fires explosions was the highest in 2012 with 7.58% (55 cases) followed by year 2009 with 3.39% (34 cases), year 2010 with 3.39% (25 cases), year 2011 with 6.03% (57 cases) and year 2013 with 6.74% (43 cases), which indicates a steady increase in the number of ship accidents. Majority of reasons for ship fires explosions were lack of safety awareness. Since those accidents happen on the sea, fires, once they happen, tend to get serious due to absence of on board & nearby fire extinguishing facilities, public fire service's uneasy access to them and great influences of natural factors such as wind and etc. Ship fires explosions are special cases unlike what happens to general edifices. So, their coping plans should focus on preventive measures since the damages those cases bring about can be detrimental. For this reason, it's necessary to research precise evacuation plans, develop ship structure & materials reinforcing fire resistance to secure more time for evacuation and enhance people's safety awareness by implementing thorough safety training.

  • Objectives : First, we analyze the contents of Dong-Eui-Bo-Gam. Second, from the view of the 'Hyung-Sang(形象:body form)' theory, we try to interpret the acupuncture points chosen in each chapter with a base on the contents of the book. Methods : We study on the on 'Hyung-Sang(形象: form)' theory of acupuncture points in each chapter on 'Shin(神)' and 'Hyul(血)' in Dong-Eui-Bo-Gam(東醫寶鑑). Results & Conclusions : The acupuncture points on epilepsy in 'Shin(神)' chapter are come from the purview of 'Shin(神)' type, fire-form, bird-form & the flushing and feeble of lower-abdomen. The acupuncture points on amnesia in 'Shin(神)' chapter are come from the purview of the powerful intestines and deficient heart-lung. The acupuncture points on dementia in 'Shin(神)' chapter are come more from the purview of 'Shin(神)' type, fire-form, bird-form. And the acupuncture points on sudden palpitation in 'Shin(神)' chapter are come from the purview of phlegen form syndromes. As the epistaxis and hematemesis on 'Hyul(血)' happen more the heat of fire than extravasated blood, the acupuncture points on epistaxis and hematemesis in 'Hyul(血)' chapter are come from the purview of 'Shin(神)' type, fire-form, bird-form and Yang-Myeong body. And as well as the acupuncture points on hematemesis in 'Hyul(血)' chapter are come possibly from the purview of 'Wind-form'. The acupuncture points on feeble hematemesis in 'Hyul(血)' chapter are come from the purview of 'The body form on the deficiency of medium energy'. And the acupuncture points on melena in 'Hyul(血)' chapter are come from the purview of 'Hyul(血)' type.
