Context-based Web Application Design
Jinsoo Park(Jinsoo Park) 한국전자거래학회 2007 한국전자거래학회지 Vol.12 No.2
웹 기능의 향상과 웹 관련 기술의 발전, 레거시 시스템과의 통합 필요성 증대, 자주 변하는 웹 콘텐츠와 구조 등으로 인하여 웹 애플리케이션을 개발하고 관리하는 일이 과거보다 훨씬 더 복잡하게 되었다. 그러나 이러한 다양한 요인들을 고려하는 포괄적인 웹 애플리케이션 설계 방법론은 아직 존재하지 않고 있다. 따라서 본 연구에서는 이러한 요인들을 고려한 컨텍스트 기반의 웹 애플리케이션 설계 방법론을 제시하고자 한다. 본 연구에서 제시하는 방법론에서는 웹 정보를 전달하는 메커니즘에 따라 구분되는 9 종류의 웹 페이지 형태와 웹 페이지 간의 다양한 의미 관계를 정의하는 7 종류의 링크 형태 및 설계 과정 중에 사용되는 여러 종류의 컴포넌트 역할을 구별하는 소프트웨어 컴포넌트 형태 등 다양한 종류의 모델링 기법들을 소개하고 있다. 뿐만 아니라 이 방법론은 ‘콤펜디엄(compendium)’이라 불리는 일단의 관련된 정보 클러스터들로 이루어진 독창적인 웹 애플리케이션 모델을 사용하고 있다. 하나의 콤펜디엄은 주제(theme), 컨텍스트 페이지, 링크 및 컴포넌트로 구성된다. 이러한 접근방법은 모듈 방식의 설계에 유용할 뿐만 아니라 항상 변하는 웹 애플리케이션의 콘텐츠와 구조를 관리하는데도 도움이 된다. 본 연구에서 제시한 방법론은 의미적으로 응집력이 있고 구문적으로 느슨히 결합된 유연한 웹 디자인 산출물을 생성하는데 도움이 될 것이다. Developing and managing Web applications are more complex than ever because of their growing functionalities, advancing Web technologies, increasing demands for integration with legacy applications, and changing content and structure. All these factors call for a more inclusive and comprehensive Web application design method. In response, we propose a context-based Web application design methodology that is based on several classification schemes including a Webpage classification, which is useful for identifying the information delivery mechanism and its relevant Web technology; a link classification, which reflects the semantics of various associations between pages; and a software component classification, which is helpful for pinpointing the roles of various components in the course of design. The proposed methodology also incorporates a unique Web application model comprised of a set of information clusters called compendia, each of which consists of a theme, its contextual pages, links, and components. This view is useful for modular design as well as for management of ever-changing content and structure of a Web application. The proposed methodology brings together all the three classification schemes and the Web application model to arrive at a set of both semantically cohesive and syntactically loose-coupled design artifacts.

beings. The most common form of biological melanin is a complex polymer of either or both of 5,6- indolequinone and 5,6-dihydroxyindole carboxylic acid. Micronized TiO2 has been also widely used as a representative inorganic pigment for the formulation of the UV-care cosmetic products. We synthesized a number of new organic-inorganic nanohybrid compounds to develop sunscreens having stronger UV protecting synergy effects from the sun for the first time. We characterized novel organic-inorganic nanohybrid compounds by 1H/13C cross-polarization magic angle spinning (CPMAS) solid-state NMR and FT-IR spectroscopy. The complexes A, B, and C, simple mixing of the L-DOPA bearing catechol unit with TiO2 nanoparticle does not show forming covalently bonded organic-inorganic nanohybrid compounds. On the contrary, the complexes D, E, and F show that the line shape changes and chemical shifts of phenoxy carbons of catechol move downfield upon forming the catecholate with Ti (IV). Relationship between the composition of organic-inorganic hybrid and SPF improvements will be studied more in detail in the near future.

<P>A new voice activity detector for noisy environments is proposed. In conventional algorithms, the endpoint of speech is found by applying an edge detection filter that finds the abrupt changing point in a feature domain. However, since the frame energy feature is unstable in noisy environments, it is difficult to accurately find the endpoint of speech. Therefore, a novel feature extraction algorithm based on the double-combined Fourier transform and envelope line fitting is proposed. It is combined with an edge detection filter for effective detection of endpoints. Effectiveness of the proposed algorithm is evaluated and compared to other VAD algorithms using two different databases, which are AURORA 2.0 database and SITEC database. Experimental results show that the proposed algorithm performs well under a variety of noisy conditions.</P>

The purpose of this paper is to identify the nonlinear roll damping characteristics of the Rigid-hulled Inflatable Boat (RIB). Using the measured motion response data of the rolling system, an inverse problem (suggested by Jang et al. (2009)) is formulated for the identification of the nonlinear roll damping. The results of the herein paper are presented by comparing the exact experimental data from the free-roll decay test with the simulated one by the inverse problem approach.
On-demand acoustic droplet splitting and steering in a disposable microfluidic chip

<P>On-chip droplet splitting is one of the fundamental droplet-based microfluidic unit operations to control droplet volume after production and increase operational capability, flexibility, and throughput. Various droplet splitting methods have been proposed, and among them the acoustic droplet splitting method is promising because of its label-free operation without any physical or thermal damage to droplets. Previous acoustic droplet splitting methods faced several limitations: first, they employed a cross-type acoustofluidic device that precluded multichannel droplet splitting; second, they required irreversible bonding between a piezoelectric substrate and a microfluidic chip, such that the fluidic chip was not replaceable. Here, we present a parallel-type acoustofluidic device with a disposable microfluidic chip to address the limitations of previous acoustic droplet splitting devices. In the proposed device, an acoustic field is applied in the direction opposite to the flow direction to achieve multichannel droplet splitting and steering. A disposable polydimethylsiloxane microfluidic chip is employed in the developed device, thereby removing the need for permanent bonding and improving the flexibility of the droplet microfluidic device. We experimentally demonstrated on-demand acoustic droplet bi-splitting and steering with precise control over the droplet splitting ratio, and we investigated the underlying physical mechanisms of droplet splitting and steering based on Laplace pressure and ray acoustics analyses, respectively. We also demonstrated droplet tri-splitting to prove the feasibility of multichannel droplet splitting. The proposed on-demand acoustic droplet splitting device enables on-chip droplet volume control in various droplet-based microfluidic applications.</P>
