  • A rock slide in amount of 100 tons in weight happened at 7: 10 a.m., 4th October 1982, on the southwestern ridge of Mt. Seunghag, Busan City. The original rock mass of the rock slide is located 850m west from the Dangri Crushed Stone Quarry. The geology of the area consists of agglomerate, andesite, andesitic tuff, and shale hornfels of the Cretaceous Yucheon Group. The rock blocks were first shifted along the steep joint plane on an andesite outcrop at the site and then to the eastern foot of the mountain slope where some private houses are placed. The mountain slope is covered with thick superficial soil. A slided monolithic-block with 83 tons in weight from the rock slide met with an accident of striking against a house with a tremendous force, to which much damage was done as much as its half was destroyed. The rock-slided block pierced the board-floored room only posited at the center and by the bedroom of the house making a pass like a bullet hole, and hence cut a big pine tree with 24 centimeters in diameter at a distance of 26 meters down the house. However nobody was killed or injured in the stricken house, though seven family members were stayed therein at the very time of accident. They really met a rare opportunity in an unhappy disaster. Measurements of the rock slide were made in the course of the field survey. The monolithic mass was transported by way of saltation, rolling, and sliding to a distance of 300 meters down along the slope dipping 30$^{\circ}$ east. It took about 16 seconds front tile outcrop to the terminal. The acceleration value of the monolithic rock slide is 2.35m/sec$^2$.

  • 1. Objectives We know that the origine of the pe-tsai is from 백채(白菜; pronounced as bak-tsai, meaning white vegetable). But some literatures said that the japanese butterbur(Petasites japonicus (Sieb. et Zucc.) Maxim) is from 백채(白菜;: pronounced as bak-tsai), too. These two words have same origin. It makes us get into a mess. So We are about to study the origine of the pe-tsai more. Also, we investigated its historical origin, properties and Sasang constitutional medicine's efficacy. 2. Methods We reviewed farmings(e.g. 山林經濟, 林園經濟法), dictionarys(e.g. 訓蒙字會), encyclopedia(e.g. 物名攷), books on herbs and medicines to summarize literatures about the pe-tsai. 3. Results and Conclusions (1) The origin of term, pe-tsai is sung, named after a pine tree(松), chineses character pronounced as song) which we can see throughout a year. Also, pe-tsai was called white vegetables(白菜, pronounced as bak-tsai) because its appearance is green and white. Therefore, the pronounciation of sung derives from its character and we also say bak-tsai(白菜), which came from its looks. (2) Today we pronounce pe-tsai inro bae-tsu(배추) in korean. There are pronunciational developments of this word : bak-tsai(白菜) $\to$ bae-tsae $\to$ bae-tsa $\to$ bae-tsa $\to$ bae-tsae(배채) $\to$ bae-tsu(배추). (3) Our ancestor used bak-tsai(白菜) as the name of japenese butterbur, which was different from China. The latter times of Joseon(조선), however, sometimes bak-tsai(白菜) meant pe-tsai. After the year of 1800, bak-tsai(白菜) only meant pe-tsai. So when we try to translate our ancestor's books, we must examine carefully their published year. (4) Pe-tsai is used for baby's erysipelas, boil, fever in the chest, thirst after alcohol drinking and kind of diabetes. It helps digestive organs as well. Pe-tsai is used for stress, fever in the chest and cough with fever of Soyangin and Tayangin in Sasang Constitutional Medicine.

  • Detrended correspondence analysis(DCA) and two way indicator species analysis(TWINSPAN) were applied to Pinus densiflora stands nearby Seoul area in order to classify them into several groups based on herbaceous species and environmental relationships. The eighteen Pinus densiflora stands were perferenially selected, In each stand, 30 to 60 quadrats, (20X20)cm, were randomly estabilished. In each quadrat, all stems for herbaceous plants were recorded by species and their covers were measured. In addition environmental factors such as soil depth, thickness of litter layer, soil compressibility, tree density, basal area, elevation, slope and exposure were detemined for each stand. Four to twelve soil cores were collected and physical and KDICical properties were determined. This survey was conducted form 15, July, 1985 to 22, September, 1985. Analysis of the vegetation and environmental data were performed with DECORANA and TWINSPAN. Stand ordination (DECORANA) and classification (TWINSPAN) based on herbaceous species suggest that the stands can be classified into five groups in terms of herbaceous species composition and environmental relationships. Type I, Type II, Type III, Type IV and Type V were classified to SUBMESIC-CLO-SED-CANOPY (Artemisia keiskeana, Carex nanella), MESIC-CLOSED CANOPY (Spodiopogon sibiricus, Miscanthus sinensis, Carex nanella, Pteridum aquilinum, Melampyrum rosium), SUBMESIC-OPEN CANOPY (Carex nanella, Spodiopogon sibiricus, Miscanthus sinensis), XERIC-CLOSED CANOPY (Carex nanella, Spodiopogon sibiricus, Carex nanella), and XERIC-OPEN CANOPY (Arundinella hirts, Spodiopogon sibiricus, Carex nanella), respectively. These results were consitent with environmental trends on stan ordination. Application of the ordination and classifiaction to Pinus densiflora stands were effective as a approach on obtaining perliminary ecological information.

  • Korean embroidery is the long historical industrial arts of real life and has handed down Korean sentiment up to now. Korean traditional embroidered pattern is designed to wish someone's health and luck, who uses the embroidery on the clothes and the goods in real life. Especially, the ten longevity symbols' design is represented as 10 which means perfection in oriental philosophy, the sun, mountain, cloud, water, crane, rock, turtle, pine tree, the elixir of life and deer; these 10 symbols show how ancient Korean believe and wish perpetual youth. However, fiber material used embroidery relic has difficulty in preserving for long period compared to other relic descended from historical events for long time and their preserved state isn't so good owing to have been used directly in the real life. Therefore, it is essentially embossed to preserve the embroidery relic and pattern, and make DB for the data. With preservation of the pictures about the handicraft, it's necessary to preserve embroidery technique and make DB through digital imagination. Through the process, we can apply Korean embroidery image to cul-duct package and digital image related field, and it will be helpful to make the tradition popular. In this study, through the research for the embroidery technique applied pattern on the embroidery relic of ten longevity symbols, we'll establish the cultural identification of Korean embroidery image and then develop a worldwide Korean image.

  • Foreign bodies in the airway are very import-tant and not uncommon conditions in the field of E.N.T., and practically there are many reports of them. Occasionally, it can be followed by some pulmonary complications and technical difficulty to remove. Therefore, foreign body in the trachea-bronchial tree is serious and, on occasion, fatal. Recently, the authors experienced 7 interesting cases of foreign bodies in the airway and a brief review of literature was made. Case 1. (1 year old male): A bit of walnut was coughed out spontaneously. Case 2. (2 years old male): A bit of raw chestnut was removed from the right main bronchus. Case 3. (21 Years old male): A pushpin was removed from the left main bronchus. Case 4. (1 year old male): A kind of bean was removed from the right main vronchus. Case 5. (4 years old male): A coiled steel spring (1.1cm$\times$2cm) was removed from the subglottic region. Case 6. (5 years old female): A shell of pine nut which had been impacted in the wall of right main bronchus was removed during right middle and lower lobectomy. Case 7. (2 years old male): A metal nail was removed from the rightposterior basal segmental bronchus during right lower lobectomy.

  • Reproduction of antique document is of importance with the concept of sharing the their contents and original aspects in terms of textual and artistic message. 'Pine tree ink stick' and 'Oil ink stick' are greatly enjoyed in their uses in the most written documentary works. Thus, it is said that the approach of this study has implied considerable meanings to cultural aspects. In this work, we have performed to investigate the reproduction and restoration study for antique documents. With comparison and analysis of some types of "ink stick", we have prepared several ink samples, controlling viscosity, surfactant, thickness agent, and applied these inks to the target antique document. Several reproduced samples showed a practical application possibility in terms of reproduction and restoration.

  • The characteristics of the spread of a forest fire are generally related to the attributes of combustibles, geographical features, and meteorological conditions, such as wind conditions. The most common methodology used to create a prediction model for the spread of forest fires, based on the numerical analysis of the development stages of a forest fire, is an analysis of heat energy transmission by the stage of heat transmission. When a forest fire breaks out, the analysis of the transmission velocity of heat energy is quantifiable by the spread velocity of flame movement through a physical and chemical analysis at every stage of the fire development from flame production and heat transmission to its termination. In this study, the formula used for the 1-dimensional surface forest fire behavior prediction model, derived from a numerical analysis of the surface flame spread rate of solid combustibles, is introduced. The formula for the 1-dimensional surface forest fire behavior prediction model is the estimated equation of the flame spread velocity, depending on the condition of wind velocity on the ground. Experimental and theoretical equations on flame duration, flame height, flame temperature, ignition temperature of surface fuels, etc., has been applied to the device of this formula. As a result of a comparison between the ROS(rate of spread) from this formula and ROSs from various equations of other models or experimental values, a trend suggesting an increasing curved line of the exponent function under 3m/s or less wind velocity condition was identified. As a result of a comparison between experimental values and numerically analyzed values for fallen pine tree leaves, the flame spread velocity reveals has a error of less than 20%.

  • Objectives : This paper seeks to discover and compile the information of the types of Korean medical herbs that are recorded in China's medial herbs literatures. Following this, the special characteristics of each herb and the differences in the description of each Korean herb found in different literatures and ages. Methods : First, the literatures were searched for the names of countries, regions, and people used in Korean peninsula, and a database was compiled based on the findings. Texts with no relation to the subject matter were discarded, and the rests were listed in the order of publication. The special characteristics of the medical herbs found in these literatures were then studied. Results & Conclusions : Total of 69 medical herbs were found in 34 literatures. These medical herbs could be categorized into three: those with superior quality, those that are different from the medical herbs used in China, and those that are not available in China. The medical herbs with superior quality are: Gonpo(昆布), Insam(人參), Omija(五味子), Tosaja(?絲子), Haesongja(海松子), Sesin(細辛), Baekbuja(白附子) and more. We can deduce that these medical herbs were regarded as superior in quality compared to their counterparts in China because they grow in the northeast region where pine tree thrive and a home to many areas with seas and mountains, and also with four distinctive seasons.

  • As a primary step to develop natural preservative for extending the shelf-life of kimchi, the effect of 102 edible plants, 21 antimicrobial agents and related compounds on kimchi fermentation was studied. Among 42 oriental medicinal plants tested, Baical skullcap and Assam indigo were found to be highly effective for maintaining the fresh state of kimchi. Although Bugbane, Red mangolia, Bushy sophora, Szechuan pepper, Chinese quince and Scisandre significantly inhibit the growth of Lactobacilli, their effect was not high enough to be used as raw materials for kimchi preservative. When the effect of 32 herbs and spices was tested, peppermint, cinnamon, lemon balm, clove, hop, rosemary, sage, horseradish and thyme showed high antimicrobial activity against kimchi microorganisms. Among them, the effect of clove ranked top. When it was added to fresh kimchi, initial cfu value ($2.4{\times}10^{6}cfu/g$) changed little even after 2 day's fermentation ($2.6{\times}10^{6}cfu/g$). Sensory test was not a good criteria to evaluate the effect of herbs and spices, since their highly specific flavors affected the taste of kimchies. Twenty eight fruits, vegetables and related plants were tested, but only leaves of pine tree, persimmon and oak leaves showed a significant bactericidal effect, finally contributing to the storage of kimchi. In addition, when 21 natural preservatives and other compounds were added individually to fresh kimchi, nisin and caffeic acid could inhibit fermentation.

  • The number of forest fire under various conditions such as year, month, time, day of the week, region, damaged species, cause, and damaged area are checked, and the statistics of the forest fire causing materials in recent 14 years ('91-'04) are analyzed. The result shows that the year majority of forest fires had happened in last 14 year was 2001 and most of forest fire occurred in April, Sunday, around 14:00 to 15:00. The most damaged region is Gyeongsangbuk-Do, followed by Gangwon-Do, Jeollabuk-Do, and Gyeonggi-Do. The most damaged species is pine tree. The main causes of forest fires are accidental fire and incineration of a field boundary; however, recently, incendiarism is increased. The result of analysis on the damaged area shows that small fires under 5 ha occurred most frequently and large fires (over 30 ha) occurred mostly in Kangwon province (44.2%). The result also shows that the large forest fires (1,113 minutes) require 7.5 time more than the small forest fires (148 minutes). Especially, since average damaged area caused by large forest fire was about 470 ha per incident.
