Soek(Xi) was the highest ranked shoe that was worn with the primary formal dress in East Asian countries including ancient Korea and China. This article examined Joseon's Seok as discussed in previous studies, and it explored factors such as the wearers' status, wearing situations, its morphology, its materials, and its colors in the Great Han Empire period (1897~1910), and then extracted three morphological characteristics of the Korean Seok to examine its origin. The results of the study are as follows. For women, the Seok in the Great Han Empire period was worn with Won-sam(圓衫) and No-eui(露衣) as well as Jeok-eui(翟衣), and hence its range of wearing was extensive. Also, red Seok was worn with deep red colored Dae-sam(大衫)-styled Jeok-eui in the Joseon period(1392~1897), and blue Seok with deep blue Jeok-eui in the Great Han Empire period. This suggests the possibility that wearing of deep blue Jeok-eui occurred after 1906 in terms of the use of blue Seok. As for its morphology, its leg-less form was maintained into the late Joseon period, and there were no great changes in its name. The characteristics of the Korean Seok's morphological structure consisted of a shoe leg, the wood-less bottom and pearl ornament. As a result of the examination of the origin of those characteristics, it has been clarified that the form in which Gu, Eok, Jun(純), are attached in the structure with a shoe leg originated from the combination of Hwa(靴) and Li(履) after the two types of shoes were alternately worn in the Song (宋) period. Also, it was confirmed that the woodless bottom appeared between the periods from Wei Jin Northern and Southern Dynasties(魏晉南北朝) to Sui(隋), and the pearl ornament occurred in the Jin(金) period.

This paper examines the way that the principles of coloration for Hoecha(繪次) and Sucha(繡次) were applied for shoe making in ancient China and Korea. Hoecha is the principle of drawing, and Sucha is the principle of embroidery. Hoecha and Sucha is the application principle of the five colors(五方色) from the five elements(五行: metal, wood, water, fire, and earth). Hoecha matchs a color with the opposite side color, and Sucha matchs a color with the beside color. A shoe consists of Sinul(body of shoe) and ornaments attached to it. According to the ratings of shoes, Hoecha and Sucha were differently applied for coloration of Sinul and its ornaments. In general, shoes were classified into Seok and Gu. For Seok, which was the high-ranked shoes, Hoecha was applied, while Sucha was applied to Gu, the low ranked shoe. As Hoecha was originally a principle of coloration for patterns on tops(jacket. 上衣), it was applied to the high ranked shoes i.e., Seok. Also, as Sucha was a principle of coloration for patterns on bottoms(skirt. 下裳), it was applied to the low ranked shoes i.e., Gu. Thus, black was decorated on red Seok, blue on white Seok, red on black Seok, yellow on hyeon(玄: a kind of black color) Seok, and white on blue Seok, all of which were applications of the principle of Hoecha. As the application of the principle of Hoecha to Seok was also done for red Seok for males and females in late Joseon, and red Seok for the crown prince in the period of the Korean Empire, black decorations were used for red Sinul. However, for blue Seok, worn by females in the period of the Korean Empire where Ming's systems prevailed, black decorations were used, which was an application of Sucha. Though there had been no discrimination between genders in the application of Hoecha and Sucha originally, the low ranked principle of coloration was applied to Seok for females.

High efficiency deep blue and pure white phosphorescent organic light emitting diodes were developed using a new deep blue phosphorescent dopant, tris((3,5-difluoro-4-cyanophenyl)pyridine) iridium (FCNIr). A high quantum efficiency of 9.1 % with a color coordinate of (0.15, 0.16) at 1,000 cd/$m^2$ was obtained in the deep blue device and a high quantum efficiency of 15.2 % with a color coordinate (0.30, 0.32) was obtained in the pure white organic light-emitting diodes. The quantum efficiency of the pure white device is the best quantum efficiency value reported in the pure white device up to now.

Interaction between wood-destroying basidiomycetes and blue stain fungi were studied during conjoint cultivation on 2% malt extract agar. The ability of basidial cultures to decolourise dark pigments of ophiostomatoid fungi was the main characteristics estimated during this investigation. Antrodiella hoehnelii(S28/91), Bjerkandera fumosa(137), Gleophyllum odoratum(124), Trametes versicolor (B18/91) cultures were found to be the most active in decreasing dark colour of blue stain fungi colonies. The cultures were recommended for further development as agents of biopulping and control of blue stain fungi in wood chips.

The existing conjugated blue emitting material polymer which has been used for the two-wavelength method white-emission has good stability and low operating voltage as merits, but the imbalanced carrier transport has been indicated as problem area. We have introduced a novel blue emitting material having perylene moiety unit with hole transporting ability and blue emitting property and triazine moiety unit with electron transporting ability into the same host chain. We have synthesized N-[p-(perylen-3-y1)pheny1]methacry1 amide (PPMA) monomer and [N-(2,4-dipheny1-1,3,5-triazine)pheny1 methacry1 amide] (DTPM) monomer having blue light-emitting unit and electron transport unit, respectively by three steps. A novel non-conjugated blue emitting material Poly[N -[p­(perylene-3-y1) pheny1] methacry1 amide-co-N-[P-(4,6-dipheny1-1,3,5-triazine-2-y1]pheny1]methacry1 amide] (PPPMA-co-DTPM) copolymer having electron transporting unit was synthesized by the solution polymerization of PPMA and DTPM monomers with an AIBN initiator and showed high yield of $75{\%}$. It was very soluble in common organic solvents, and the fabrication of the thin film using a spin coating method was very simple. The PPPMA exhibited a good thermal stability.

Acute toxic methemoglobinemia is an infrequent complication of the use of various drugs. Severe methemoglobinemia is very often fatal. Methylene blue is an effective drug in the treatment of methemoglobinemia patients. However, failure to respond to methylene blue has been described in patients with sulfhemoglobinemia, chlorate poisoning, and glucose-6-phosphate dehydrogenase deficiency. It is even possible that hemolysis may occur due to methylene blue treatment itself. We encountered a case of a 71-year-old woman who developed methemoglobinemia caused by alprazolam intoxication. She presented with hemolytic anemia and did not respond to methylene blue. In spite of concerted N-acetylcysteine therapy, the hemolytic anemia became aggravated and the patient died eleven days after intoxication.

This study was performed to investigate the frequency of blue staining fungal species collected from pine trees, Experimental Forests of Kangwon National University in Korea based on their morphological characteristics. In addition the tolerance to fungicide, Woodguard, was assessed to get basic knowledges for preventing blue stain of wood. Totally Leptographium-type fungi were dominated by 79.3% among Ophiostomatoid fungi associated with scolityd bark beetles in pine trees. Leptographium-type Ds-isolates which have unusual morphology were collected as frequency of 17.0%. The most distinct differeneces of these Ds-isolates from L. procerum were the presence of roughened hyphae and flask-shaped conidiophores that have never been mentioned formerly for L. procerum, but since these Ds-isolates formed black concentric rings being a property of L. procerum, the Df-isolates were characterized as Leptographium-type fungi, which are the most common species with the highest frequency by 33.2% in this particular area. According to our experimental results, Leptographium-type Ds- and Df-isolates were very resistant to fungicide, Woodguard, therefore it was suggested that a new method for wood protection from the blue staining fungi should be developed. Exact identification of blue staining isolates collected from pine trees is keep going.
