  • After many casualties with conventional bulk carriers in recent years, double hull bulk carrier was proposed ta enhance the structural safety of side shell and transverse bulkhead. In this paper, two alternative structural designs of double hull bulk camel were executed based an the Lloyd's rule, and the results were examined in comparison with the existing single hull bulk carrier in the viewpoints of the increase of weight and construction cost. The relative construction concept was used to certify the economical validity of double hull bulk carrier.

  • Internet의 확대와 망의 진화에 따라 현 통신 방식은 기존 회선 교환 방식에서 패킷 교환 방식으로 진화를 한다. NGN(Next Generation Network)이란 정확하게 정의를 내리기는 어렵지만, 개념적으로는 현존하는 모든 서비스(Voice, Data, Video 등)들과 미래에 나타날 멀티 서비스를 통합하여 수용할 수 있는 패킷 기반의 통신망을 의미한다. 이러한 개념은 망의 통합을 목적으로 하는 BcN(Broadband Convergence Network, 이하 BcN)로 진화하고 있다. 하지만, 진정한 의미의 BcN은 Legacy 회선 교환 방식(include Wireless Network)과 패킷 교환 방식의 모든 망 사용자에게 동일한 서비스를 제공하는 것이며, 이것은 Convergence Service라는 개념으로 정리를 할 수 있다. 본 논문에서는 이와 같은 접근을 Next Generation Convergence Service(이하 NGcS)로 정의를 한다. 논문에서는 NGcS 구축을 위해 지능망 서비스와 연계하여 접근을 할 것이며, INAP(Intelligent Network Application Protocol), WIN(Wireless Intelligent Network) 및 CAP(CAMEL Application Part) 등의 제어방식에 근거한다. 이러한 방식들에 대한 연동에 대해 논하며, NGcS 구축을 위한 Service Switching Function 설계 방법과 서비스를 트리거(Trigger)하기 위한 방법에 대해 논한다.

  • Extensive investigations on cast to cast variations observed in steels have underlined the role of thermocapillary or surface tension driven fluid flow in welding operations. The behavior of weld pool under the electric arc is however affected by possible arc modifications linked to microchemistry variations in materials & this limits to some extent the real contribution from surface tension effects. Thus, electron beam welding with high vacuum was used to investigate thermo-capillary effects on thin austenitic stainless steels & nickel based alloys. The weld pool was monitored by video observations to estimate the importance of fluid flow during the melting & solidification phase. The results underline the importance of fluid flow on [mal solidification.

  • With strong biotin binding affinity ($K_D=10^{-14}M$), the tetrameric feature of streptavidin could be used to increase the antigen binding activity of a camel heavy chain (VHH) antibody through their fusion, here stained with biotinylated horseradish peroxidase and subsequent immunoassays ELISA and Western blot analysis. For this application, we cloned the streptavidin gene amplified from the Streptomyces avidinii chromosome by PCR, and this was fused to the gene of the 8B9 VHH antibody which is specific to green fluorescent protein (GFP) antigens. To express a soluble fusion protein in Escherichia coli, we used the pUC119 plasmid-based expression system which uses the lacZ promoter for induction by IPTG, the pelB leader sequence at the N-terminus for secretion into the periplasmic space, and six polyhistidine tags at the C-terminus for purification of the expressed proteins using an $Ni^+$-NTA-agarose column. Although streptavidin is toxic to E. coli because of its strong biotin binding property, this soluble fusion protein was expressed successfully. In SDS-PAGE, the size of the purified fusion protein was 122.4 kDa in its native condition and 30.6 kDa once denatured by boiling, suggesting the tetramerization of the monomeric subunit by non-covalent association through the streptavidin moiety fusing to the 8B9 VHH antibody. In addition, this fusion protein showed biotin binding activity similar to streptavidin as well as GFP antigen binding activity through both ELISA and Western blot analysis. In conclusion, the protein resulting from the fusion of an 8B9 VHH antibody with streptavidin was successfully expressed and purified as a soluble tetramer in E. coli; it showed both biotin and GFP antigen binding activity suggesting the possible production of a tetrameric and bifunctional VHH antibody.

  • Soil temperature is one of the most important environmental factors that govern hydrological and biogeochemical processes related to diffuse pollution. In this study, considering the snowmelting and the soil freezing-thawing processes, a set of computer codes to estimate winter soil temperature has been developed for CAMEL (Chemicals, Agricultural Management and Erosion Losses), a distributed watershed model. The model was calibrated and validated against the field measurements for three months at 4 sites across the study catchment in a rural area of Yeoju, Korea. The degree of agreement between the simulated and the observed soil temperature is good for the soil surface ($R^2$ 0.71~0.95, RMSE $0.89{\sim}1.49^{\circ}C$). As for the subsurface soils, however, the simulation results are not as good as for the soil surface ($R^2$ 0.51~0.97, RMSE $0.51{\sim}5.08^{\circ}C$) which is considered resulting from vertically-homogeneous soil textures assumed in the model. The model well simulates the blanket effect of snowpack and the latent heat flux in the soil freezing-thawing processes. Although there is some discrepancy between the simulated and the observed soil temperature due to limitations of the model structure and the lack of data, the model reasonably well simulates the temporal and spatial distributions of the soil temperature and the snow water equivalent in accordance with the land uses and the topography of the study catchment.

  • This is a study of CHOK-DU-RI(族頭里) a black crown-like headpiece worn by woman on formal occasion in Chosun Dynasty and has succeeded until now. CHOK-DU-RI was originated by BOKTAK worn by Mongolian noblewomen and inflowed to the last period of Koryo dynasty under occupation of Yuan. The documentary records of O-JU-YON-MUN-CHSNG-JON-SAN-KO( by Lee Kyu-kung CHUNG-JANG-KWAN-JON-SUH by Lee Tock-mu and KO-SA-TONG by choe Nam-sun verify CHOK-DU-RI is a custom of mongolian fusion that was affected by KO-KO of Yuan and was formed. Ko-Ko is the same as BOKTAK. It is assumed KO-KO is a borrowed name as its transcription varies. The name was given according to its appearance which is certified by the record CHANGCHUN-CHIN-IN-SEO-BANG-YU-RAM-KI. It says that it can be simply named KO-KO as its edge is alike ad goose or a duck. In addition KO-Ko was called CHOGTAI in case of being added a camel fur that is JUGDUR. CHOGTAI similarily pronounced with CHOK-DU-RI which of being added a camel fur that is JUGDUR, CHOGTAI similarily pronounced with CHOK-DU-RI which provd CHOK-DU-RI was originated in Mongol. The shape of BOKTAK is very high and wided toward the top with the top with the angle getting more pointed and a feather stuck on the side. But its height got lower and its size smaller as it did gradually Koreanized to a CHOK-DU-RI. The use of CHOK-DU-RI has been settled since the last period of Chosun Dynasty. It came to stay as a popular custom when King Young-jo and Jong-jo wanting to do away with the corrupt practice of KA-CHE encouraged women at that time to do their hairs with CHOK-DU-RI instead of KA-CHE. It is as follows the classification of CHOK-DU-RI. First classified by a use group is divided into ceremonial use such as the seven treasures CHOK-DU-RI and jeweled CHOK-DU-RI. Hereby it is assumed that CHOK-DU-RI was used regardless of fortune. Secondly it varies by its type of frame. There are SOM CHOK-DU-RI OHT CHOK-DU-RI and O-YOM CHOK-DU-RI a kind of SOM CHOK-DU-Ri formed a base of O-YOM-MO-RI. The third group by jeweling has WHE-BONG CHOK-DU-RI and TA-BONG-CHOK-DU-RI JEwele CHOk-DU-RI can be still seen being commercially lent and worn by the brides at nuptical ceremonies performed in tradition of fashion and when worn bya bride as she gives her parents to her parents-in-law.

  • This paper is to find the theme and meaning of the Beauvais Grotesque tapestry considered a conundrum. The three works are chosen from Beauvais Grotesque consisting of six tapestries, which are The Offering to Pan, The Musician and Dancers, The Camel in the J. Paul Getty Museum. I analyzed these works by dividing them into grotesque ornaments, chinoiserie motifs, and scenography. The Offering to Pan shows the influence of Raphael's Grotesque tapestry, but Beauvais work followed the design of Jean Berain's Grotesque with arabesque. In The Musician and Dancers, chinese ceramics, textiles, and Chinese people in edge were noted. Especially, the Chinese with yellow skin in the border reveals the European gaze on China at that time. In the 18th century, Chinoiserie was prevalent through stage designs rather than books. The Camel, playing Brighella, makes it clear that this tapestry is a stage of Comedia dell'arte. The characteristic of Comedia is a mixture of genres such as music and dance, with no scripting 'improvisation.' Features of Comedia are 'improvisation' without a script and a mixture of genres such as music and dance. Thus, the Grotesque tapestry transfers the stage of the Comedia into threads woven. In addition, the horizontal stage decoration with the disappearance of the perspective vanishing point is related to the era of regent of Philippe d'Orl?ans (1674-1723). Above all, the grotesque, Chinoiserie, and scenography are all fantasies separated from reality. Therefore, the Beauvais Grotesque tapestry represents of 'improvisation' and 'fantasy' in which there is no narrative theme or meaning, as if the script of Comedia did not exist.

  • Mutton was the meat of choice among the Saudi Arabian citizens in Riyadh Metropolitan area, 1986-1987, followed by chicken, camel meat, fish and beef. The desirable taste of mutton that represented 68% of the total respondents was the main reason for its preference to other meats. The study also showed that Najdi sheep, which is the predominant local breed, enjoy a priority in its meat consumption among the other indigenous and exogenous breeds of sheep in the central region of the Kingdom. A loyalty to the Najdi sheep was witnessed even when the unit price was assumed to be doubled. Purchasing Najdi sheep for non-family consumption had dropped, although still ranked first among the breeds of sheep readily available in the local markets. The results also showed that, 41% of the sample individuals purchased at least one sheep per family per month, and more consumption of mutton took place during the winter months than during the summer.
