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.

인터넷에서 폭주상황이 발생한 후에는 네트워크 성능이 급격하게 저하되는 문제점을 개선하고자 RED 알고리즘이 제안되었으며, 현재 IETF 에서는 표준으로 사용되고 있다. 그러나 RED 알고리즘은 고정된 파라미터 값을 사용하여 가변적인 네트워크 트래픽 상황에 능동적으로 대처하지 못하는 문제점을 가지고 있다. 본 논문에서는 기존의 RED 알고리즘의 문제점인 고정된 파리미터 값 설정으로 인한 문제점을 해결하기 위하여 효율적인 RED 알고리즘을 제안한다. 제안한 알고리즘은 현재의 가변적인 트래픽 상태에 따라 패킷폐기확률을 조정하여 라우터와 같은 게이트에서의 폭주상황을 효율적으로 제어하도록 하였다. 또한 제한안 알고리즘은 NS-2를 이용하여 시뮬레이션을 수행함으로써 성능을 검증하였다.

Recently many studies have been done on the Random Early Detection(RED) algorithm as an active queue management and congestion avoidance scheme in the Internet. In this paper we first overview the characteristics of RED and the modified RED algorithms in order to understand the current status of these studies. Then we analyze the RED dynamics by investigating how RED parameters affect router queue behavior. We show the cases when RED fails since it cannot react to queue state changes aggressively due to the deterministic use of its parameters. Based on the RED parameter analysis, we propose a self-adaptive algorithm to cope with this RED weakness. In this algorithm we make two parameters be adjusted themselves depending on the queue states. One parameter is the maximum probability to drop or mark the packet at the congestion state. This parameter can be adjusted to react the long burst of traffic, consequently reducing the congestion disaster. The other parameter is the queue weight which is also adjusted aggressively in order for the average queue size to catch up with the current queue size when the queue moves from the congestion state to the stable state.

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.

The aim of our study understands the influence of meteorological factors relating to the formation of the red tide, and monitors the red tide by satellite remote sensing. The meteorological factors have directly influenced on red tide formation. Thus, it was possible to predict and apply to red tide formation from statistical analyses on the realtionships between red tide formation and meteorological factors, and also to realize the near real time monitoring for red tide by satellite remote sensing.

Red scabream, Pagrus major , is a valuable aquaculture species in Korea , but spontaneous eye abnormality occurred in cultured individuals . The incidence of eye abnormality was 4% in the group of cultured red scebream. The abnormality was characterized by unilateral and bilateral exophthalmos, opacity and lens pathology. Lense prolapse was found in two cases. Lenses in diseased fishes was considerably small in diameter and eyes were deformed as a whole. In the group of induced hybrid red scabream Pagrus major (♀) x black seabrearn Acanthopagrus schlegeli (♂), the incidence of eye abnormality wa~ the same 4%, but only opacity was registered. Opacity was also found in two of sixteen examined Wild-caught red seabrcam. Histopathological changes of lenses in cultured red seabreem included vecuolated cytoplasm of lens fibers, necrosis of fibers in central part of lens, folding and increase in thickness of lens capsule, and epithelial proliferation beneath the anterior lens capsule. In affected eyes no parasites or gas bubbles were found.

Raoultella species are gram-negative, non-motile, aerobic bacilli that are primarily considered as environmental bacteria. Raoultella planticola is reportedly a rare cause of human infections. Also, the definite pathological mechanism of Raoultella planticola is currently unknown. We report a case of pneumonia caused by Raoultella planticola.
