Hydrogen is considered to be the most important future energy carrier in many applications reducing significantly greenhouse gas emissions, but the safety issues associated with hydrogen applications need to be investigated and fully understood to be applicable as the carrier. Therefore, there is a considerable demand for further research concerning the dispersion of hydrogen/air mixture clouds and the possible consequences of their ignition. In this study, the dispersion of hydrogen gas in atmosphere has been analysed with atmospheric condition by concerning the buoyancy of hydrogen. The hazard ranges to wind direction increase with wind speed and the stability of atmosphere. The concentration of hydrogen at just above ground is nearly zero due to buoyancy of hydrogen gas. Therefore, the ignition probability of hydrogen gas cloud is low and the hazard of explosion or fire associated with hydrogen gas is relatively low comparing with the other fuel gas such as propane or butane.

Building hardware joints are welded in most cases, which have risks of fire and explosion. Besides, the secondary damage of the destruction of the welded parts can be caused by the horizontal displacement of the structure due to earthquake or wind load. This paper compared the horizontal displacement following abilities of welded building hardware and non-welded building hardware. To do this, We conducted actual formation shake table test, and checked on the horizontal displacement following ability of structure by comparing their responses to earthquake load. We made the 2m-high framework to examine the responses of the actually constructed building hardwares, and analyzed the displacement responses of the welded-typed, non-welded-typed, and cruciform bracket building hardwares. We conducted the test by increasing acceleration rate until displacement reached 40mm corresponding to allowable relative story displacement II. The result of the test showed that the building hardware using welding work made cracking and breakage on welded connections of welded building hardware, but non-welded building hardware with no use of welding work and cruciform bracket building hardware make no problem, and that non-welded building hardware is superior to that of the welded building hardware in the horizontal displacement following ability due to earthquake or wind load.

Objectives The purpose of this study is to analyze sinusitis patients who visited the department of pediatrics, OO Korean medicine hospital by using their age and to classify the clinical type by Korean medical theory. Methods The study was conducted based on 178 cases that consisted of sinusitis patients (from 1 to 15 years old) who visited OO Korean medicine hospital from March 2014 to March 2015. We analyzed the age of patients and classified them by the clinical type by reviewing patient's charts. After that, we compared the results with the results of previous studies. Results and Conclusions 178 Patients were studied. 2-years-age group was 19.7% of the study group which was higher than that of previous studies. The Lung-Kidney Yin Deficiency (肺腎陰虛) group was 33.1%, Wind-Heat (風熱) group was 29.8% and the Wind-Cold (風寒) group 18.5%, Spleen-Lung Qi Deficiency (脾肺氣虛) group was 15.7% and the Heart-Spleen Qi Deficiency (心脾氣虛) group was 2.8% of the study group. Children are full of Yang but lack of Yin (陽常有餘陰常不足) so they easily transform into heat and fire (化熱化火). The patients who had sinusitis were most likely to suffer from the common cold for more than a week, once a month. 45.1% of the people from the study group was suffered from common cold more than a week, and 43.8% of the people got common cold once a months. About 21.6 % and 18.3% of the people got common cold twice a month and once every 2 months, respectively. The remaining 15.7% got cold during the season changes.

Objectives & Methods: We investigated 36 books to study etiology, pathology and acupuncture & Moxibustion treatment of Gak-Gi Result and Conclusion 1. Gak-Gi is a disease of legs. In the past, it was called Wan-poong(緩風) or Gueol(厥). Currently it is divided into two kinds; the Seup-Gak-Gi(Damp Gak-Gi) in which the legs swell; The Gun-Gak-Gi(Dry Gak-Gi) in which the legs do not swell. 2. Gak-Gi may be caused by exogenous wind, coldness, dampness and Excess of phlegm or damp-heat. It also can be caused by weakness of vital energy(Myungmoon fire;命門火), kidney Yin deficiency and vital energy deficiency in the Stomach and Spleen. 3. Gak-Gi-Pal-Hyul(Eight acupoints for Gak-Gi; 脚氣八穴) are GB31(Poonsi; 風市), ST32(Bok-to; 伏兎), ST35(Dok-bi; 犢鼻), Nae-seul-an(Extra point; 內膝眼), ST36(Chok-samni; 足三里) ST37(Sang-goho; 上巨虛) ST39(Hagoho; 下巨虛) GB41 (Choc-imup; 足臨泣) 4. Treatment plans for Gak-Gi are removing the exogenous wind, coldness and dampness, regulating meridians, alleviating the pain and swelling, more importantly, tonifying vital energy and nourishing Spleen and Stomach. 5. Three out of Eight acupoints for Gak-Gi, ST36(Chok-samni; 足三里), ST37(Sang-goho; 上巨 虛), ST39(Hagoho; 下巨虛) are Lower sea points of Fu organs( Stomach, Large Intestine, Small Intestine). Five out of Eight acupoints for Gak-Gi, ST32(Bok-to; 伏兎), ST35(Dok-bi;犢鼻) are onthe Stomach meridian, and Nae-seu1-an(Extra point; 內膝眼) is on the Spleen meridian. This result indicates that regulation of Middle-cho(中焦) is important in the treatment for Gak-Gi.

Objectives : To analyze symptoms of olfactory dysfunction caused by COVID-19 from a Korean Medical Perspective. Methods : Previous studies dealing with olfactory dysfunction accompanying COVID-19 were studied and analyzed for general characterization. Physiology and pathology of olfactory functions within the classical texts of Korean Medicine were collected and analyzed, through which symptoms of olfactory dysfunction in COVID-19 were examined. Results : Olfactory dysfunction manifested in high ratios in the early stages of confirmed COVID-19 cases, at times independent of other nasal symptoms such as blockage or discharge. There was a high chance of loss of taste being accompanied, while mental problems such as a tendency to have difficulty concentrating were present as well. In most cases, recovery took one to two weeks. From a Korean Medical perspective, physiology of olfactory function is closely linked to the Lungs, Ancetral Qi[宗氣], and the Heart, while its dysfunction could be explained by pathological factors such as Wind-Cold, Fire stagnation, Qi deficiency, Wind stroke, etc. Conclusions : In the context of external contraction disease[外感病], olfactory dysfunction could be caused by problems in the Lungs and Stomach that are responsible for breathing, or the Heart which is involved in recognizing and differentiating scent. General characteristics of COVID-19 imply it to be closely related to the Heart. In clinical application, overall symptoms need to be considered in diagnosis and treatment planning, after which further approaches could made to determine the problem to be of the Lung and Stomach, or of the Heart.

Korea has accomplished the afforestation of its forest land in the early 1980's. To meet the increasing demand for forest products and forest recreation, a development of scientific forest management system is needed as a whole. For this purpose the development of efficient forestfire management system is essential. In this context, the purpose of this study is to develop a theoretical foundation of forestfire danger rating system. In this study, it is hypothesized that the degree of forestfire risk is affected by Weather Factor and Man-Caused Risk Factor. (1) To accommodate the Weather Factor, a statistical model was estimated in which weather variables such as humidity, temperature, precipitation, wind velocity, duration of sunshine were included as independent variables and the probability of forestfire occurrence as dependent variable. (2) To account man-caused risk, historical data of forestfire occurrence was investigated. The contribution of man's activities make to risk was evaluated from three inputs. The first, potential risk class is a semipermanent number which ranks the man-caused fire potential of the individual protection unit relative to that of the other protection units. The second, the risk sources ratio, is that portion of the potential man-caused fire problem which can be charged to a specific cause. The third, daily activity level is that the fire control officer's estimate of how active each of these sources is, For each risk sources, evaluate its daily activity level ; the resulting number is the partial risk factor. Sum up the partial risk factors, one for each source, to get the unnormalized Man-Caused Risk. To make up the Man-Caused Risk, the partial risk factor and the unit's potential risk class were considered together. (3) At last, Fire occurrence index was formed fire danger rating estimation by the Weather Factors and the Man-Caused Risk Index were integrated to form the final Fire Occurrence Index.

Windy meteorological conditions and dried fire fuels due to higher atmospheric instability and dryness in the lower troposphere can exacerbate fire controls and result in more losses of forest resources and residential properties due to enhanced large wildland fires. Long-term (1979-2005) climatology of the Haines Index reconstructed in this study reveals that spatial patterns and intra-annual variability of the atmospheric instability and dryness in the lower troposphere affect the frequency of wildland fire incidences over the Korean Peninsula. Exponential regression models verify that daily high Haines Index and its monthly frequency has statistically significant correlations with the frequency of the wildland fire occurrences during the fire season (December-April) in South Korea. According to the climatic maps of the Haines Index created by the Geographic Information System (GIS) using the Digital Elevation Model (DEM), the lowlands below 500m from the mean sea level in the northwestern regions of the Korean Peninsula demonstrates the high frequency of the Haines Index equal to or greater than five in April and May. The annual frequency of the high Haines Index represents an increasing trend across the Korean Peninsula since the mid-1990s, particularly in Gyeongsangbuk-do and along the eastern coastal areas. The composite of synoptic weather maps at 500hPa for extreme events, in which the high Haines Index lasted for several days consecutively, illustrates that the cold low pressure system developed around the Sea of Okhotsk in the extreme event period enhances the pressure gradient and westerly wind speed over the Korean Peninsula. These results demonstrate the need for further consideration of the spatial-temporal characteristics of vertical atmospheric components, such as atmospheric instability and dryness, in the current Korean fire prediction system.
