  • We investigated the effects of Pd impurities on cube-textures in cold rolled and recrystallized PtPd tapes The sample were made from Pt$_{1-x}Pd_x$ alloys (x from 0 to0.34) by rolling at low temperature. The thickness of the tapes were about 100 ${\mu}$m. The PtPd[111] pole figures of X-ray Diffraction for all the samples indicated similar deformed textures. But the recrystallized textures after annealing showed that a better cube texture was formed in the sample of larger x. The final textures were sensitive to annealing time and temperature when x was increased.

  • Caminus jejuensis n. sp was collected from depth of 20 m at Geomeunyeo, Seogwipo, Jejudo Island by a SCUBA diving from April 2004 to December 2008. This new species is similar to C. chinensis from China in the composition of spicules except for the spherasters and they differ in spicule size and growth form. This species has longer orthotriaenes and spherules, smaller sterrasters and oxyasters than those of C. chinensis. This species also has many spherasters in choanosome, but C. chinensis lacks. Morever, the new species is a massive shape with wrinkles, whereas C. chinensis is a club shape with smooth surface. Description and figures of the new species are provided.

  • Pagurus undosus and Pagurus parvispina, collected from the East Sea by fishery trap, are newly recorded from Korean waters. Pagurus undosus is distinguished from other hermit crab by its right cheliped slightly elevated medially, and with broad ridge formed by deep depressions mesial and lateral to midline. Pagurus parvispina is distinguished from other hermit crab by its right cheliped covered with large spine and long tufts of setae. These species live in cold water areas and their geographical distribution is extended southwardly by the present study. A specimen of the former species, P. undosus, was found living in a shelter formed by a sponge, similar to that observed in Pagurus pectinatus. Descriptions and figures of these two species are provided in this paper. Currently, 27 species of the genus Pagurus are recorded in Korean fauna.

알러지성 자반병으로 진단받은 태음인(太陰人) 양독발반증(陽毒發斑症) 환자(患者)에 대한 치험예(治驗例) (A Case Study of Taeumin Yangdokbalban Patient diagnosed as Allergic Purpura)

  • Allergic Purpura is similar to Yangdokbalban Syndrom in Oriental Medicine. The main symptoms of Yangdokbalban Syndrom and allergic purpura are rashes and fevers in body. In Sasang Constitutional Medicine, Taeumin have an Yangdokbalban Syndrom by Ganyeol as their inherent symptomatic phamacology. An inpatient diagnosed as allergic purpura in other hospital who has fevers in body, rashes and itchings at fevers was seen to Taeumin by his external figures and internal emotions. And, he has an symptomatic distinctiveness that general conditions refreshed after sweating and can drink water in chilling. Therefore A person was diagnosed as Taeumin with allergic purpura as above distinguishing symptoms, the curative value will be outperformed by taking Galgeunhaekitang.

  • The purpose of this study is to discover the interrelationship between modern costumes and Seung-Hee Choi's dancing costumes in 1930s. Seung-Hee Choi, who was a dancing pioneer in Korea, introduced the modern dancing costumes for the first time in Korea. The results are as followed ; First, we can find Eroticism in Choi's dancing dress. Choi's dancing costume had used gold thread, silver thread, spangle, see-through and a half-naked body clothing that decorated with beads and cords. It is similar to modern costumes in ubjet mtter, silhouette, design, and so on. Second, the influence of Futurism was in her dancing costumes, that is, it represented asymmetry designs and rectilineal figures. Third, not only beauty but also a Functionalism was expressed in her dancing costumes. Functional beauty was shown through bias cut, pleats, slit, and so on.

  • Masses of the uterine cervix were detected from two dogs, being a 2-year-old female Yorkshire tarrier and a 12-year-old female Basset Hound. Grossly, the masses measuring 3.O$\times$3.O$\times$4.0 cm and 12.O$\times$l2.O$\times$10.07m were prominent, sharply circumscribed, fleshy tumors in the uterine cervix. Histologically, the masses consisted of smooth muscle cells interwoven in bundles, some of which were cut longitudinally (elongated nuclei) and others transversely. Tumor cell nuclei were ordinarily cigar shaped and had rounded blunt ends in the longitudinal plane. There were low mitotic figures without abnormal ones. From these results, these cases were diagnosed as leiomyoma of the uterine cervix. To our Knowledge, no similar tumors have been reported in the uterine cervix.

  • In this study, a new method is proposed generating 3D wire-frames of building using the lowest level topology, points, which are input by human operators. Through the procedure, it is possible to make prediction occlusion points and generate the topology automatically among points, lines, surfaces from buildings. In order to adjust the error of initial values which are input manually, the least squares adjustment for model-image fitting is carried out using the edge information of aerial imagery. And also, model fitting procedure is done making all surfaces plane of buildings by the least squares adjustment. As a result of those procedure, 3D building models are refined similar to real figures of buildings.

  • This study was carried out to elucidate the seasonal changes of amylase an nitrate reductase activities in Zoysia japonica Steud. The seasonal changes of the amylase activity AA) in aboveground parts appeared high activity from the beginning of May to the beginning of July and in autumn showed an activity of rapid decreasing tendency. But, the AA in winter(Nov. 15~Feb 28 was not almost detected. The seasonal changes of nitrate reductase activity(NRA) in various organs appeared a very similar figures to the seasonal changes of AA. But, the NRA in the root was not almost detected.

  • Pattern Recognition measures the ability of learners to distinguish between two sets of shapes or figures. Locating similar patterns on either side of the presented problem determines a learner's capacity or aptitude for science over general studies. At Ajou University's Institute for Scientifically Enabled Youth, we conducted research using a sample composed of middle school students with general and scientific backgrounds. The result proved that Pattern Recognition measures a different creative talent other than problem solving. In our opinion, Pattern Recognition would be a method better suited to elementary learners over those in middle or high school.
