The Korean architect Chung Guyon(1945~2011) is the translator of the Korean edition of Gourna: A Tale of Two Villages(1969) written by the Egyptian architect Hassan Fathy(1900~89). This fact, along with the facts that Chung changed the topic of his graduation thesis(1983) for UPA no.6 in Paris and that he became a supporter of earth architecture after he returned to Korea in 1986, confirms that Chung was strongly influenced by Fathy's architecture in Gourna project. Therefore, the present paper aims at extracting didactic characteristics of Fathy's architecture from the book and comparing them with those of Chung's architecture. The categories of the characteristics extracted from the book (or his architectural activities in the Gourna project) are: clay/earth architecture; communicative and cooperative architecture; and critical stance towards society, and these are commonly found in Chung's architecture, too, not without differences from Fathy's owing to the gap between the two architects' contexts. Reviewing these characteristics, this paper argues that Fathy and Chung tried to improve society in each context, working as both architect and social activist.

One of the primary advantages of acrylic resin teeth is their ability to bond chemically to the denture base resins. Fracture od acrylic resin teeth from a maxillary denture, however, is not uncommon. Bonding failures have been attributed to faulty boil-out procedures that fail to eliminate all traces of wax from the ridge lap surfaces of the teeth and to contamination of the ridge lap surface by careless application of tinfoil substitute. Attempts to increase the strength of the bond between acrylic resin teeth and heat-cured denture base resin include grinding the glossy ridge lap surface (in fluid system), painting the ridgelap surface of the teeth with monomer-polymer solution, and cutting retention grooves in the ridge lap surface of the teeth. This latter method has been tested by applying a tensile force in a labial direction to the incisal part of the lingual surface of the acrylic resin teeth. A progressive shear compressive load was applied at an angle to the lingual surface of acrylic resin teeth bonded to denture base acrylic resin. No statistically singificant advantage was derived by preparing retention grooves of different shapes in the ridgelap surface of the denture teeth.

In this paper, to provide various services of QoS, and moreover applying traffic ratio to CAC(Call Admission Control) algorithm tested how long average data rate and the average packet delay time. When CAC algorithm is not applied, traffic mixture ratio is 1:1:4:4, the FTP Service 0.4, web services 0.6, streaming service 0.7, the packet delay requirements are not satisfied. On the other hand CAC Algorithm is applied, all the service of packet delay are satisfied with arrival rate. Therefore, we can make sure that applying of CAC of traffic control WWW, FTP, Video, VoIP can guarantee the various services of QoS.

We used nine microsatellite DNA markers to estimate genetic variation among wild and cultured populations of the sea squirt Halocynthia roretzi. The loci were polymorphic, with 6-32 alleles, and allelic richness ranged from 6.0 to 26.1 in each population. The wild and the cultured populations had similar mean heterozygosities ($H_O$ and $H_E$), allele numbers, and allelic richness. One cultured population with softness syndrome had a lower mean in the observed heterozygosity ($H_O$ = 0.57) and higher mean inbreeding coefficient ($F_{IS}$ = 0.261) than any other populations. This suggests that the loss of genetic variation in the diseased population might be due to increased inbreeding. A neighbor-joining tree and pairwise population estimates of $F_{ST}$ showed moderate genetic differentiation between the wild and the cultured populations. Additionally, the softness syndrome population was genetically divergent from wild populations, but it was genetically close to the cultured populations.

This research started from the premise that East Asia - China, Korea and Japan - played a remarkable role in the development of modern architecture. In this study, attention is paid to the lack of a synthetic research about the influence of East Asia on European modernism as a counterpart to its influence on American modernism. Thus, the intention of this paper is to construct an integrated discourse on the East Asian contribution to European modern architecture. By analyzing recently published/presented articles on the related subjects, this study suggests how European modernists encountered the East, what attracted them to the East, and how they applied East Asian aesthetics in their designs. While a number of architects adopted East Asian formal elements directly, at times superficially, others extracted the underlying principles. As a whole, this analysis offers insights at several levels. First, it provides a balance to the view of the East Asian influence on modern architecture by providing an investigation into its influence on European modernism as a counterpart to its influence on American modernism. Second, the multi-faceted nature of modern architecture is further illuminated in this study. Third, an important example of "positive-Orientalism" is provided, which contrasts with the rather negative image implied by E. Said's 'Orientalism'. In conclusion, this paper provides a critical assessment of the fundamental motive of European modernists' adoption of East Asian aesthetics.

Objective : Hydrocephalus is one of the major complications following spontaneous subarachnoid hemorrhage (SAH). However, the risk factors of the hydrocephalus after SAH are not still well known. This study was focused on verification of the causal relationships between the development of hydrocephalus and SAH. Methods : The patients who developed hydrocephalus after rupture of aneurysms were studied. To obtain prognostic factors regarding to hydrocephalus, several parameters such as age, sex, hypertension, location of aneurysm, existence of intraventricular hemorrhage (IVH) and intracerebral hemorrhage (ICH), Glasgow coma scale (GCS), Hunt-Hess SAH classification & Fisher Grade on admission and the ratio of frontal harn of lateral ventricle diameter to skull inner table diameter at this level (FH/ID) were studied retrospectively. Results : The development of hydrocephalus following SAH is multifactorial. The age, IVH, FH/ID ratio were related to hydrocephalus in analysis. There is a low clinical correlation between sex, hypertension, location of aneurysm, existence of ICH, GCS, Hunt-Hess SAH classification, Fisher Grade on admission and hydrocephalus. Conclusion : Knowledge on risk factors related to the occurrence of hydrocephalus may help guide neurosurgeons in the long-term care of patients who have experienced aneurysmal SAH.

This study was done to determine a new qualitative base for educating and evaluating patients by comparing a 60 or over age group with a 20-30 age group when rising from supine to erect stance. Sixty normal adults were devided into 60 or over and 20-30 aged groups. Each persons was asked to standing from the supine position. This process was recorded by two video cameras. The results was classified into the three existing movement categories. And then they were analyzed by percent rate. The results showed that each group had its own different and special characteristics. This means that physical therapists need to select the best motor patterns according to age in teaching functional tasks such as rising from supine to erect stance.

Glass ceramics for dental crown prosthesis were prepared by crystallization of CaO-MgO-SiO2-P2O5-TiO2 glasses. Their crystallization behaviors have been investigated as a function of heattreatment temperature and holding time in relation to mechanical properties. The results are as follows: Vickers hardness and bending strength of glass ceramics increased due to the precipitation of apatite, whitlockite, $\beta$-wollastonite, magnesium titanate, and diopside crystal phases within glass matrix. The final crystalline phase assemblages and the microstructures of the glass ceramics were found to be dependent on heat-treatment temperature and holding time. Vickers hardnes and bending strength of glass ceramics increased with increasing heat-treatment temperature and holding time.
