  • During the study of the distribution of cellular slime molds in Halla mountain of Korea, a new yellow-pigmented Dictyostelium was isloated. This exibited several distinctive features which differed from the published species, and was designated as a new species, Dictyostelium jlavidum sp. n. Hong et Chang (Type strain HL-1). It was cultivated at $20-22^{\circ}C$ on weak nutrient agar media, 0.1 L-P in association with Escherichia coli. Sorocarps were 4-10 mm or more in length, conspicuously yellow throughout or with sori, typically solitary, unbranched or sparsely and irregularly branched. Sorophores were strongly tapered from bases to tips. Bases were typically well-formed disks in form or conically expanded. Sori were yellow to yellowish in color, and the pigmentation intensified with age. Spores were long and thin elliptical, mostly $4.8-9.6{\times}1.9-3.8\;(ave.\;7.3{\times}2.8)\;\mu\textrm{m}$, L/B index about 2.4-2.8, without polar granules.anules.

  • This study is to analyze Korean-Chinese women's Costume in Yabian with factors such as reform opening-up, economic growth, change of social values, development of technology, more education opportunities and influence of mass media. It divides the 1990's into two halves. Photos, interview, observation and relevant literature were used for this study. Even though economy grew rapidly, they needed to purchase daily goods other than clothes. In a way that they preferred practicality, it showed somewhat it was still developing. The trend in the first half of the 1990's was characterized : first, Synthetic or artificial fibers and ready-made suits were popular ; second, there still remained the men's style ; third, they wore Tanrikoo(彈力袴), Tisingkoo(體型袴), Jiaotakoo(脚袴) because of its properties of activeness and comfort ; fourth, shoulders looked ore prominent with pads as they were used in Chungsanfoo(中山服) ; fifth, clothes in grey and dark blue was in fashion ; sixth, they wore hand-made knit vests and sweaters and often mountain-climbing gears for its light and warm quality ; seventh, along with opening-up, various materials and colorful clothes were in style, which satisfied women's desire for beauty. They decorated Hanbok(韓服), using sleeves with colors, golden ornaments, flower patterns embroidery, materials of different color in collar and tie and dyes of sleeves and skirts. In the first half of the 1990's when the opening-up was beginning, there were diverse styles and colors in fashion, yet not close to good quality. As the economy grew, the second half of the 1990's was characterized by good palate, individuality, favouritism on foreign goods, rapid change of fashion. For instance, fur coat and woolen fabric were favored. Economic growth led to abundance of cloth, dyes and decorative materials. In addition, people possessed more clothing and it was possible for them to wear both Hanbok and wedding dress in wedding ceremony. People placed their standards on competency and financial ability rather than ideology. Worship disappeared and individuality arose. Therefore, apparel functioned not only as protection but as suits with aesthetic purpose. This resulted in introduction of bold style, imitation of western countries and extension of use of Hanbok. With the help of mass media, transportation, telecommunication, contact with Korean company and civilians, Korean and western cultures, through Korea, were accepted. Change in structure of economic status caused excessive spending and more educational opportunities that enabled people to accept foreign culture quickly. Values moved onto new, beautiful and better characteristics. it was possible to have suits ready-made due to improvement of mass production and cotten, wool, linen, silk became popular owing to technology. New technology, the bases of mass consumption, increased possession of clothing and accelerated change of fashion. In summary, women's Costume in Yanbian were affected by the factors in economy, politics, culture contact as well as change of society and technology.

  • The study was conducted to investigate the tissue and chemical characteristics of rusty root epidermal cells. In histological study, the rusty symptoms were frequently observed in the epidermis of ginseng root and to be yellow under microscopic observation. Disks of the epidermal cell tissue of the rusty root were usually 2 and 3 times greater in the number of cell layer and thickness of cell wall than the healthy root, respectively. The color degree of methanol extracts from the rusty root epidermis was 5.5 times higher than that of the healthy root. And the extracts of rust matter in the root epidermis were easily dissolved in polar solvents compared to nonpolar solvents. UV-absorption spectra of methanol extracts in various fractions of phenolics showed a maximum peak between 275∼280 nm. The crude lipids and phenolic compounds such as acid insoluble bound phenolics, acid insoluble esterified phenolics, acid insoluble condensed phenolics, insoluble bound phenolics and free phenolics were also more in the rusty root epidermis than in the healthy one. Fe content in the rusty root epidermis was 2.7 times higher than that of healthy one. It was presumed that the phenolic compounds(precursor of the rusty) in association with lipid and iron in the root epidermis might defence the root when ginseng root was depressed by the unfavorable conditions in soil and/or portions of a root system were subjected to anoxic conditions.

  • Glass was fabricated by using refused coal ore obtained from Dogye coal mine in Samchuk. We additionally used soda ash and calcium carbonate as raw materials to make a glass with the chemical composition of soda-lime glass. And the properties of glass were measured when limestone was used as natural raw materials instead of calcium carbonate as chemical raw materials. Transparent glass was fabricated by melting raw materials at $1550^{\circ}C$ for 1 hr in an electrical furnace. The various kinds of glass samples were fabricated according to the kinds of refused coal ore and glass cullet. The optical properties of transmittance and color chromaticity were measured by UV/VIS/NIR spectrometer and the thermal properties of thermal expansion coefficient and softening point were measured. Transparent glass with the transmittance of over 70% in visible range was fabricated by using normal refused coal ore and black colored glass with the transmittance of 0~35% was fabricated by using shel1 type refused coal ore. Therefore, it is concluded that refused coal ore can be used for raw materials to manufacture secondary glass products such as a glass tile and foamed glass panel for construction material.

  • This study was to investigate the effects of the hot compress pack on alleviating local muscular discomfort, stiffness in limbs as well as the chronic pains such as migraine in terms of hemodynamics. In this study, the hot compress band was put on the neck and the local physiological change on the stimulation site and the cranial blood circulation change were examined. We recruited healthy volunteers (n=8, mean age: 32.13 (4.61)), who participated in the magnetic resonance imaging (MRI) study. Local skin color and temperature were measured for the local effect of the hot compress band and the changes of intra-cranial and extra-cranial blood vessels were examined with MR angiography (MRA) images. The skin temperature increased from $36.4^{\circ}C$ at the rest condition to $36.7^{\circ}C$ and $37.1^{\circ}C$ after 15 min and 30 min stimulation, respectively. The change of the extra-cranial blood vessels between pre-stimulation and post-stimulation of 30 min was significantly increased (+38.8%), while the change of the intra-cranial blood vessels was negligible. In this study, we demonstrated that the hot compress band on the neck yielded the increase of local skin temperature on the stimulation site and it made an effect on the extracranial circulation. In conclusion, the stimulation with a hot compress could facilitate the blood circulation, causing to relieve the muscular discomfort, stiffness in limbs as well as the chronic pains such as migraine.

  • Octagonal green glass bottle with long neck(녹유리장경각병) was found in the tomb of the princess Hwayu who was King Youngjo's daughter by a concubine while the tomb was exhumed and buried in another place around Bucheon City, Gyeonggi-do. This octagonal glass bottle is dark green. It was made in AD 1736-A1795 because it was cngraved an inscription of "건륭년제" the bottom. This glass bottle was taken an X-ray radiography and tested adhesives and restoration materials for the conservation. Loctite 401 was suitable as considering the translucency of the glass bottle, good adhesive property and reversibility of the adhesive so it was chosen. A minute piece of the glass was analyzed the composition and lead isotope ratio. Major chemical composition of the glass bottle consisted of SiO2, K2O, and PbO system and the ratio was 68: 18.5:5.7. Green color of glass bottle was due to Fe2O3 and CuO. When the glass bottle was made, quartz as raw material of silica and K2O as natural saltpeter(KNO3) were utilized. As a result of lead isotope ratio analysis, it was suggested that the galena as raw material of lead for glass making came from the southern part of China. These results are expected to become useful data in background of glass culture and circulation study of old glass.

  • The eldest son of the crown prince is very important social status next to the crown prince deciding fundamentals of a state in Chosun dynasty which laying stress royal authority. Accordingly, Chakbong(冊封) of the eldest son of the crown prince has been done independently like as Chakrei(冊禮) of the crown prince. The existig record of Chakrei(冊禮) of the eldest son of the crown prince. The existing record of Charkrei(冊禮) of the eldest son of the crown prince are Hyunjongwangseon(顯宗王世孫), Euisoseson(懿昭世孫), Youngjowangseson(英祖王世孫), Hungjongwangseson(憲宗王世孫) of 4 books for Chakreidogameuigue(冊禮都監儀軌) being preserved in Kyujangkak(奎章閣). The transition of classified clothes are stated on Wangse sonchakreidogameuiguebanchado(王世孫冊禮都監儀軌班次圖) for Chakrei(冊禮) of the eldest son of the crown prince. Its details are as below. Finally, there is no changes in constitution of the costume of the eldest son of the crown prince Chakrei(冊禮) called as Ssanggodong(雙童髮)·Gongjungchak(空頂 )·Ojangbok(五章服) on documentary records depsitefo no explanation of Banchado(班次圖). Secondly, The classified clothes of the eldes sion of the crown prince Hcakreibanchado(冊禮班次圖) are on . We have acknowledged that Kwanmo(冠帽) of Dangbukwanwon(堂部官院) has been changed from Heugrib(黑笠) to Samo(紗帽) since Youngjowangseson(英祖王世孫), Euibok(衣服) from Chungpo(靑袍) to Nokdanryung(綠團領), the costume of Euijangsu(儀仗手) from Chunggun(靑巾) to Whangchorib(黃草笠) and changed again to Hongpimoja(紅皮帽子), Chungeui(靑衣) changed to Hongeui(紅衣). Also we know that Kwanmo(冠帽) of Kyogun(轎軍) has been changed to Pimoja(皮帽子) with high top, Chungeui(靑衣) changed to Hongeui(紅衣). The costume of Byulgam(別監) has been changed from Nokgun(綠巾) to Jogun( 巾), Nokpo(綠袍) changed to Pimoja(皮帽子) with high top, Chungeui(靑衣) changed to Hongeui(紅衣). The costume of Byulgam(別監) has been changed from Nokgun(綠巾) to Jogun( 巾), Nokpo(綠袍) changed to Hongpo(紅袍), that of Suri(書吏) changed from Chungeui(靑衣) to Huekeui(黑衣). Accordingly, the transition of costume color to red stands for the briliance. Thirdly, regarding the constitution of the eldest son of the crown prince Chakrei(冊禮), that of Euisoseson(懿昭世孫) & Youngjowangseson(英祖王世孫) are same for Unggolta(態骨朶), Youngjagi(令字旗), Keumdungja(金 子), Eundungja(銀 子), Mojul( 節), Jaksun(雀扇), Chungkae(靑蓋), Chungyangsol(靑陽率). In case of Hunjongseson(懿昭世孫), Baktakgi(白澤旗) is added. On Youngjowangseson(英祖王世孫), Chungilsol(靑日率) and Kiringi(麒麟旗) are added. However, we know that the constitution of the eldestson of the crown prince Hunjong(憲宗) Chakrei(冊禮) is quite different that of previous constitution. i.e. : Hongae(紅蓋), Baktakgi(白澤旗), Samkaggi(三角旗), Kagdangi(角端旗), Byukbonggi(碧鳳旗), Jujakgi(朱雀旗), Kuemdungja(金 子), Eundungja(銀 子), Eunribgwa(銀立瓜), Kuemhwanggwa(金 瓜), Eunhwhanggwa(銀 瓜), Kuemwolbu(金鉞斧), Bongsun(鳳扇), Huegkae(黑蓋). Also the kinds of Eujanggi(儀仗旗) are various which are similar to the constitution of The Crown Prince(世子) Chakrei(冊禮).

  • Korean language has the characteristics that the pronunciation of phoneme units such as vowels and consonants are fixed and the pronunciation associated with a notation does not change, so that foreign learners can approach rather easily Korean language. However, when one pronounces words, phrases, or sentences, the pronunciation changes in a manner of a wide variation and complexity at the boundaries of syllables, and the association of notation and pronunciation does not hold any more. Consequently, it is very difficult for foreign learners to study Korean standard pronunciations. Despite these difficulties, it is believed that systematic analysis of pronunciation errors for Korean words is possible according to the advantageous observations that the relationship between Korean notations and pronunciations can be described as a set of firm rules without exceptions unlike other languages including English. In this paper, we propose a visualization framework which shows the differences between standard pronunciations and erratic ones as quantitative measures on the computer screen. Previous researches only show color representation and 3D graphics of speech properties, or an animated view of changing shapes of lips and mouth cavity. Moreover, the features used in the analysis are only point data such as the average of a speech range. In this study, we propose a method which can directly use the time-series data instead of using summary or distorted data. This was realized by using the deep learning-based technique which combines Self-organizing map, variational autoencoder model, and Markov model, and we achieved a superior performance enhancement compared to the method using the point-based data.
