With the spread of Internet, e-business using Internet technology is being actively developed and operated. Currently, on behalf of the international e-business framework, International standard such as ebXML and Web Service is being advanced. We are able to publish and search business information through ebXML and Web Service and then actual trading between partners is accomplished. By the way, it is Registry that play an important part in e-business. Registry is an e-business infrastructure for enabling building, deploying, and the discovery of business Information. We can do e-business through Registries dynamically and share the resources. Representatives of Registry are ebXML and UDDI used as an international standard. We will meet with some problems when using Registries. ebXML Is focused on B2B collaborations and Web Service Is focused on application integrations. So we must use ebXML and Web Service characteristically, and sometimes use all at need. ebXML and Web Service contain business information by Registry specific way. So When using the services offered by ebXML and Web Service, we should access each Registry by using Registry specific tools. This thesis intended to integrate business information from ebXML Registry and UDDI Registry to accomplish e-business conveniently This thesis defined the common data model as well as integrated query language for integrated access to ebXML and Web Service along with design and implementation of the system.

Nicotinamide adenine dinucleotide, $NAD^+$, and its reduced form, NADH, play important roles as coenzymes in many enzymatic reactions. Electrochemical methods for $NAD^+$ or NADH detection or generation are drawn attention because it can provide the simple and low cost platform with fairly good sensitivity. In this study, the polysiloxane viologen polymer/diaphorase/hydrophilic polyurethane (PSV/DI/HPU) modified electrodes were simply prepared and demonstrated for bio-electrocatalytic $NAD^+$ sensors. The electrodes were co-immobilized with diaphorase and polysiloxane viologen polymer as an electron mediator followed by the overcoating with HPU membrane. The mixture of the enzyme and the electron mediator was well stabilized within HPU membrane and exhibited good reversibility and stability. The sensitivity was 0.2 $nA{\cdot}{\mu}M^{-1}$ and the detection limit was 28 ${\mu}M$ with a response time of 50 s ($t_{90%}$). The capability for NADH sensor was also observed on the PSV/DI/HPU electrode.

Multi-criteria decision making (MCDM) algorithms play an important role in ensuring quality of service in an integrated HetNets (Heterogeneous Networks). The primary objective of this paper is to develop a multi-criteria vertical handoff decision algorithm (VHDA) for best access network selection in an integrated Wireless Local Area Network (WLAN)/Universal Mobile Telecommunications System (UMTS)/Worldwide Interoperability for Microwave Access (WiMAX) system. The proposed design consists of two parts, the first part is the evaluation of an Analytic Hierarchy Process (AHP) to decide the relative weights of handoff decision criteria and the second part computes the final score of the weights to rank network alternatives using Simple Additive Weighting (SAW). SAW ranks the network alternatives in a faster and simpler manner than AHP. The AHP-SAW mathematical model has been designed, evaluated and simulated for streaming video type of traffic. For other traffic type, such as conversational, background and interactive, only simulation results have been discussed and presented in brief. Simulation results reveal that the hierarchical modelling and computing provides optimum solution for access network selection in an integrated environment as obtained results prove to be an acceptable solution to what could be expected in real life scenarios.

Planthopper infestation in rice causes direct and indirect damage through feeding and viral transmission. Host microbes and small RNAs (sRNAs) play essential roles in regulating biological processes, such as metabolism, development, immunity, and stress responses in eukaryotic organisms, including plants and insects. Recently, advanced metagenomic approaches have facilitated investigations on microbial diversity and its function in insects and plants, highlighting the significance of microbiota in sustaining host life and regulating their interactions with the environment. Recent research has also suggested significant roles for sRNA-regulated genes during rice-planthopper interactions. The response and behavior of the rice plant to planthopper feeding are determined by changes in the host transcriptome, which might be regulated by sRNAs. In addition, the roles of microbial symbionts and sRNAs in the host response to viral infection are complex and involve defense-related changes in the host transcriptomic profile. This review reviews the structure and potential functions of microbes and sRNAs in rice and the associated planthopper species. In addition, the involvement of the microbiota and sRNAs in the rice-planthopper-virus interactions during planthopper infestation and viral infection are discussed.

뮤지컬은 노래와 춤이 극의 플롯 전개에 긴밀하게 짜 맞추어진 연극으로 노래와 춤은 특정한 상황과 일련의 사건을 전개한다. 특히 노래는 등장인물이 지향하는 목표와 액션을 구체적으로 담아내면서 극의 중대한 변화를 일으키고 정서 환기와 증폭의 기능을 수행한다. 본 논문은 플롯 전개의 기능을 맡는 노래에 초점을 맞추어 '무대 위의 액션과 이야기를 구현하는 노래'를 '액션송'이라는 용어로 정의하고 그 역할과 중요성을 부각하고자 한다. '액션송'은 통합 뮤지컬의 극의 초반에 삽입되는 '캐릭터송'으로 부여받은 개인의 욕망이나 행동의 동기가 액션의 중심 사건인 갈등을 제공하면서 등장인물이 자신의 목표를 달성하기 위한 투쟁하는 과정을 다룬 노래이다. 즉, '액션송'은 무대 위의 액션을 가사가 있는 노래로 전달하여 음악과 서사를 유기적으로 결합한 노래를 뜻한다. 또한, 플롯을 앞으로 진전시키는(which move the plot forward) 노래이며 플롯 전개의 재료가 되는 일련의 사건 혹은 장면의 액션(Action)을 담은 노래이다. 본 논문은 우리에게 잘 알려지지 않은 '액션송'의 개념을 정리하고 연구의 토대를 마련하기 위한 것으로 뮤지컬 <공포의 꽃가게>를 대상으로 대본과 음악분석을 통해 '액션송'의 개념과 기능과 효용성을 알아보았다. 그 결과 액션송은 갈등으로 인한 긴장감을 축적하고 증폭시켜 극을 고조하게 만들며 관객의 감정몰입을 유도한다. 동시에 액션송 이후에 다음 장면에 대한 기대감을 상승시키면서 극의 재미와 흥미를 배가시키고 단일한 액션을 중심으로 한 극의 전개는 극의 내용을 선명하고 뚜렷하게 파악할 수 있게 만든다.

Greenhouse gases (GHGs) such as carbon dioxide ($CO_2$), methane (CH$_4$), nitrous oxide ($N_2$O), chlorofluorocarbons (CFCs), sulphur hexafluoride (SF$_{6}$), together with water vapour ($H_2O$) and ozone play an important role in determining the earth's climate. The primary cause of the enhancement of GHGs is the global use of fossil fuels to generate heat, power, and electricity for a growing world population, as well as the changes in the land use, especially for agriculture. In addition, biomass buring and biofuel emissions play major roles in the GHG emissions in the Asian region because they produce large amounts of carbon monoxide (CO), nonmethane volatile organic compounds(NMVOC), black carbon(BC) and other gases.

Macrophages, found in circulating blood as well as integrated into several tissues and organs throughout the body, represent an important first line of defense against disease and a necessary component of healthy tissue homeostasis. Additionally, macrophages that arise from the differentiation of monocytes recruited from the blood to inflamed tissues play a central role in regulating local inflammation. Studies of macrophage activation in the last decade or so have revealed that these cells adopt a staggering range of phenotypes that are finely tuned responses to a variety of different stimuli, and that the resulting subsets of activated macrophages play critical roles in both progression and resolution of disease. This review summarizes the current understanding of the contributions of differentially polarized macrophages to various infectious and inflammatory diseases and the ongoing effort to develop novel therapies that target this key aspect of macrophage biology.
