The purpose of this study suggest the fashion of communication for 21th century fashion. Especially, Memphis fashion have the possibility of communicating through objects. The results of this study are as follows : First, Memphis idea is to make design into a sophisticated, conscious instrument of communication. As the Memphis fashion points out : design is an extraordinary tool for communicating because its intrinsic characteristic is the fact that it is used and distributed anyway, even without communicating anything. The Memphis fashion is trying to connect design and industry to the broader culture within which fashion moves. Second, Using different materials provides not only new structural Possibilities. but - above all - new semantic and metaphoric possibilities, order modes of communication, another language, and even a change of direction, broadening of perspective, appropriation and digestion of new values and the concomitant rejection of traditional structures that renewal always Involves. The memphis fashion works on the fabric of contemporaneity (lurex yarn, latex, chrome metal and steel) and contemporaneity means computers, electronics, a new awareness of the body. mass exercise and tourism. Third, color in Memphis has never been an ideological vehicle. As with decoration it is born tilth the design, forming an integral part of the structure. It alters the objects molecules. It works as a mass, as an intrinsic feature of a certain form and volume. The Memphis fashion was realized the introduction of ultramodern science into such experimental and creative implementation as optical motive, brilliancy of colour of electronic medium in audition to metallic fabric and high technical synthetic fiber. A color tilth pop culture connotations that weaver between technological allusions and Mcdonald's.

Lotus leaf has a special dual micro and nano surface structure which gives its highly hydrophobic surface characteristics and so-called self cleaning effect. In order to endow PVDF hollow fiber membrane with this special structure and improve the hydrophobicity of membrane surface, PVDF hollow fiber composite membranes was obtained through the immersion coating of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) dilute solution on the outside surface of PVDF support membrane. The prepared PVDF composite membranes were used in the vacuum membrane distillation (VMD) for the desalination. The effects of PVDF-HFP dilute solution concentration in the dope solution and coating time on VMD separation performance was studied. Membranes were characterized by SEM, WCA measurement, porosity, and liquid entry pressure of water. VMD test was carried out using $35g{\cdot}L^{-1}$ NaCl aqueous solution as the feed solution at feed temperature of $30^{\circ}C$ and the permeate pressure of 31.3 kPa. The vapour flux reached a maximum when PVDF-HFP concentration in the dilute solution was 5 wt% and the coating time was kept in the range of 10-60 s. This was attributed to the well configuration of micro-nano rods which was similar with the dual micro-nano structure on the lotus leaf. Compared with the original PVDF membrane, the salt rejection can be well maintained which was greater than 99.99 % meanwhile permeation water conductivity was kept at a low value of $7-9{\mu}S{\cdot}cm^{-1}$ during the continuous testing for 360 h.

England is a significant base for international trade in Europe, and dispute resolution through arbitration is active. Therefore, due to the geographical relationship with the European continent, the settlement of trade transactions and disputes with European countries is one of the most essential tasks. In this regard, arbitration procedures in England have been actively used for a long time. In England, dispute resolution methods through arbitration have been developed centered on merchant groups such as guilds from the 16th century and have been actively used until today. However, the arbitration procedure also had the characteristics of the common law because there was no legislation related to arbitration. Therefore, arbitration based on common law was carried out until the first half of the 19th century. In the 'Arbitration Act 1889', two types of arbitration systems, 'common law arbitration' and 'statutory arbitration' coexisted. However, in the arbitration procedure, according to the newly enacted 'Arbitration Act 1889', the arbitration agreement was binding from the time the arbitration agreement was reached. There was a way to select an arbitrator even if it was not explicitly stipulated in the arbitration agreement, and the arbitration award was quickly enforced. Arbitration under contract was preferred over common law arbitration, where withdrawal and revocation of awards were possible. However, in response to these provisions, the England courts considered the arbitration system to deprive the courts of jurisdiction, while a strengthened judicial review of arbitration procedures was done. In particular, England unified the arbitration-related laws, which had been scattered for a long time, adopted the model law, and enacted the 'Arbitration Act 1996'. Under the recognition and enforcement of arbitral awards in 'Arbitration Act 1996', Section 66 deals with the recognition and enforcement of arbitral awards and foreign arbitral awards. Section 2 of the 'Arbitration Act 1950' is inherited and used as it is. Second, it deals with the execution of arbitral awards under the New York Convention: Article 100 (New York Convention), Section 101 (Approval and Enforcement of Awards), Section 102 (Evidence Presented by a Party Seeking Recognition and Enforcement), and Section 103 (Provides Matters Concerning Rejection Recognition and Enforcement).

Biocompatibility of dense synthetic hydroxylapatite is well known and the direct bond with adjacent bone developed. The purpose of this study was to evaluate the potential of clinical application of tooth ash for preservation of alveolar ridge. For this purpose the author performed an experimental implantation of the particulate and root form of both pure dense hydroxylapatite and tooth ash in alveolar sockets immediately after extraction. The pure dense hydroxylapatite was particulate form and root form made by Calciteck Inc. The tooth ash was prepared by incineration at $950^{\circ}C$, and the syrindrical form of the tooth ash was sintered and trimmed to fit the size of the each extraction socket of 10 mongrel dogs. After sugery the clinical, roentgenographical, and histological observation was carried out. The results obtained were as follows; 1. Clinical observation disclosed no dehiscence and exfoliation due to tissue rejection. 2. Vertical resorption of alveolar bone occurred in all experimental sockets as well as the control sites on the roentgenograph. 3. Osteoclastic activity appeared at the inner surfaces of the crestal alveolar bone on the 1st week but disappeared on the 2nd week. 4. There were macrophages in the particulate form on the 1st and 2nd week after surgery but no macrophages appered in the root form. S. New bone formation was developed from the bony wall of experimental sockets and grew to bond with the implant materials. In particulate form the new bone formation did not occur in central zone independently. 6. Tooth ash implant sites were covered with the newly formed bony trabeculation from third week, but Calcitite particles were covered with soft tissue. 7. Generally the healing occurred more rapidly in control sites than in implant sites.

This paper aims to explore how Millay's love sonnets rewrite the carpe diem tradition in the complicated ways. This paper redirects critical attention away from Millay's individual experience and inner self toward the scene of literary history, suggesting that there may be more historical consciousness in Millay's sentimental and feminine "gesture." Rewriting the carpe diem tradition, Millay's sonnets reveal an awareness of the dependence of the carpe diem poems' discursive logic on the woman's coyness, its inability to accomplish its triumph over woman or time (death) without her posited reluctance. Contrary to Andrew Marvel's "To His Coy Mistress," the speakers of Millay's sonnets could never be accused of the sexual coyness; they are outspoken in their defiance of both death and lovers whose possessiveness resembles death's embrace. Moreover, as Stacy Carson Hubbard points out, by converting female sexual experience from its status as a onetime closural event to repeatable one, hence an opportunity for the general and emotional irritability productive of narrative, Millay seizes for the woman the power of "dilation" in both its sexual and its verbal forms. Furthermore, this paper argues that the woman's sex no longer invites analogies to things secret and sealed, preserved or ruined in Millay's sonnets. The woman's promiscuity implies a rejection of monumentalizing love, as well as a refusal of the fixing inherent in the carpe diem's fearful invocation of the movement of time. Throughout the love sonnets, the speaker's sexualized body produces nothing but ephemera. For Millay, this body spends its powers in hopes of having them, and the force of this spending is a perpetual and willful forgetting, which makes possible the repetition of love's story. Ultimately, Milly disturbs our critical categories by rendering permeable boundaries between modern literature and dead form of classic literature, the female speaker and male speaker.

This paper presents a novel power decoupling control scheme with the bidirectional buck-boost converter for primary-side regulation photovoltaic (PV) micro-inverter. With the proposed power decoupling control scheme, small-capacitance film capacitors are used to overcome the life-span and reliability limitations of the large-capacitance electrolytic capacitors. Then, an improved flyback PV inverter is employed in continuous conduction mode with primary-side regulation for the PV power conditioning. The proposed power-decoupling controller shares the reference for primary side current regulation of the flyback PV inverter. The decoupling controller shapes the input current of the bidirectional buck-boost converter. The shared reference eliminates the phase-delay between the input current to the bidirectional buck-boost converter and the double frequency current at the PV primary current. The elimination of the phase-delay in dynamic response enhances the ripple rejection capability of the power decoupling buck-boost converter even with small film capacitor. With proposed power decoupling control scheme, the additional advantage of the primary-side regulation of flyback PV inverter is that there is no need to have an extra current sensor for obtaining the ripplecurrent reference of the decoupling current-controller of the power-decoupling buck-boost converter. Therefore, the proposed power decoupling control scheme is cost-effective as well as the size benefit. A new transient analysis is carried out which includes the source voltage dynamics instead of considering the source voltage as a pure voltage source. For verification of the proposed control scheme, simulation and experimental results are presented.

Multichannel seismic data acquired in Ulleung Basin of East Sea for gas hydrate exploration. The seismic sections of this area show strong BSR(bottom simulating reflections) associated with methane hydrate occurrence in deep marine sediments. Very limited information is available from deep sea drilling as the risk of heating and destabilizing the initial hydrate conditions during the processing of drilling is considerably high. Not so many advanced status of gas hydrate exploration in Korea, the most of information of gas hydrate characteristics and properties are inferred from seismic reflection data. In this study, The AVO analysis using the long offset seismic data acquired in Ulleung Basin used to explain the characteristics and structure of gas hydrate. It is used primarily P-wave velocity accessible from seismic data. To make a good quality of AVO analysis input data, seismic preprocessing including 'true gain correction', 'source signature deconvolution', twice velocity analysis and some kinds of multiple rejection and enhancing the signal to noise ratio processes is carried out very carefully. The results of AVO analysis, the eight kinds of AVO attributes are estimated basically and some others of AVO attributes are evaluated for interpretation of AVO analysis additionally. The impedance variation at the boundary of gas hydrate and free gas is estimated for investing the BSR characteristics and properties. The complex analysis is performed also to verifying the amplitude variation and phase shift occurrence at BSR. Type III AVO anomaly appearance at saturated free gas area is detected on BSR. It can be an important evidence of gas hydrate deposition upper the BSR.

Chimeric animals are referred to as an organism composed of tissues derived from more than one species. In order to examine if a pluripotency of embryonic stem cells can cross the limitation of a species, we tried to establish human-mouse chimeric animals. Human embryonic stem cells were genetically modified to express eGFP using eukaryonic expression vector pcDNA 3.1 (In Vitrogene) for an easy identification. After selection with neomycin, approximately 15 cells were implanted into mouse blastocoele cavity. Ten chimeric blastocysts were transferred to one of the uterine horn of 2.5 days pesudopregnent ICR female. Out of 272 blastocysts transferred to pseudopregnant recipients 20 live newborn were obtained after 20 days. When newborn were obtained, pups were quickly removed immersed into 4% PFA. By histological examination using fluorescent microscope, green fluorescence was observed from the liver, heart, and spleen in newborn mice. Three weeks after born, presence of eGFP sequence within mouse genome (tail and kidney) was reconfirmed by PCR. eGFP sequence was amplified from the progenies of the animal suggesting a genetic transmission of the transgene. These chimeric mice having human cells at the beginning of development, are expected to recognize human cells as “self”, therefore, human cells or tissues will be able to escape the immunological surveillance of the host if grafted into the animal. These animals will serve as a good model system for studying the graft rejection in tissue transplantation and the potential of the cells to work well in many human disease.
