최근 소프트웨어 정의 네트워킹 기술에 대한 연구가 활발히 진행되면서 제어 펑면에 대한 많은 발전이 있었으나 여전히 데이터 평면의 하드웨어와 프로토콜에 대해 종속적이다. 이 문제를 해결하기 위해 데이터 평면을 프로그래밍할 수 있게 하여 white box 형태로 만드는 연구가 진행되고 있다. 본 논문에서는 하드웨어와 프로토콜에 독립적이기 위한 데이터 평면 프로그래밍 언어와 언어들의 독립성에 대해 살펴본다.

In this paper, typical types of digital format were defined and digital format selection guidelines of US's NISO(National Information Standards Organization) and LC(Library of Congress) and Denmark's The State and University Library and the Royal Library were introduced. Five sustainability factors and quality and functionality factors were raised through analysing the three sample guidelines. The sustainability factors include descriptive, independency, consistency, widely adopted, and quality. Thus, digital format selection strategies for a library were developed.

In this research paper, We have proposed an interpretation structure concerned with context-awareness which is essential to provide intelligent service. The proposed model has an interpretation structure that integrated information of both external and internal context, and been designed to keep independency between context information and application service. To verify the interpretation structure that proposed, we established a test bed (Ubi-Class) in which the concept of context awareness has been introduced to the existing class room, and constituted a scenario, and tested whether intelligent service is performed according to context interpretation.

Many applications can be parallelized by using multicore platforms. We propose a load-balancing technique for parallelizing a whole application, whose first module (H.264) has data independency and whose second module (AES) has data dependency. Instead of distributing the first module symmetrically over the multi-core platform, we distribute the data-independent workload asymmetrically in order to start the data-dependent workload as early as possible. Based on the experimental results with a compression/encryption application, we confirm that the asymmetric load balancing can provide better performance than the typical symmetric load balancing.

In this paper, we focus on the analysis of the results of CAS-K (Creative Attitude Scale-Korea) including 33 items of 7 factors. Using the analysis gives us the information about students' creative attitude for each factor. We introduce three methods of the analysis about the results of CAS-K; total scores analysis, mean value of each factor analysis, and CAS-K map analysis. We develop the CAS-K map based on the mean value of each factor and three categories of factors. These categories are divergent attitude (fluency, appropriateness), problem solving attitude (positiveness, independency, concentration), and convergent attitude (convergency, accuracy). This analysis of the results of CAS-K can be a source of creative attitude to foster mathematical creativity.

Aerial imaging is one of the most common and versatile ways of obtaining information from the Earth surface. In this paper, we present an approach by SOM(Self Organization Map) algorithm with 2 phase learning to be applied successfully to aerial images clustering due to its signal-to-noise independency. A comparison with other classical method, such as K-means and traditional SOM, of real-world areal image clustering demonstrates the efficacy of our approach.

최근 IT 산업의 발전과 더불어, 리소스가 제한된 소형 기기들의 사용이 비약적으로 증가하고 있는 추세이다. 자바는 플랫폼 독립성(Platform Independency), 보안성(Security), 네트워크 이동성(Network Mobility) 등의 장점을 가지고 있어, 이러한 소형 기기들에 자바 환경을 적용하게 되면 여러 가지 이점을 가지게 된다. 임베디드 장치나 모바일 같은 제한된 리소스를 사용하는 기기들에는 SUN 사의 CLDC(Connected, Limited Device Configuration)에서 정의하고 있는 K 가상 머신(K Virtual Machine: KVM)을 탑재하여 사용하게 된다. 본 논문에서는 실시간 운영체제 iRTOS$^{TM}$와 KVM 을 탑재한 소형 기기에서 좀더 효율적으로 KVM 의 메모리를 관리하기 위한 Garbage Collection기법을 설계하고 구현한 내용을 설명한다.

Membrane-coated tablet of isonicotinic acid hydrazide (INAH) which releases INAH at the zero-order kinetics was deveoped. It consisted of a soluble tablet core surrounded by a porous membrane which controls the diffusion rate. Tablet cores were prepared by compressing granules of INAH and polyvinyl chloride (PVC) dissolved in methyl ethyl ketone in which micronized sucrose were suspended. Diffusion rate of INAH from the tablet through the membrane was constant until the loaded INAH in the core was almost released. The rate was independent of pH of the dissolution medium. Water-soluble sucrose particles behaved as a poreproducing material in the water-insoluble PVC film coat. The pH independency of the rate was probably due to the high solubility of INAH in the water of wide pH range. The diffusion rate of INAH could be controlled by chnaging the composition of the membrane or the coat weight. This membrane-coated INAH tablet seemed to be a powerful candidate for the controlled release drug delivery system (DDS) of INAH or other highly watersoluble drugs.

In this paper a new type of filter, called the $H_2/H_{\infty}$ FIR filter, is proposed for discrete-time state space signal models. The proposed filter requires linearity, unbiased property, FIR structure, and independence of the initial state information in addition to the performance criteria in both $H_2$ and $H_{infty}$ sense. It is shown that $H_2,\;H_{\infty}$, and $H_2/H_{\infty}$ FIR filter design problems can be converted into convex programming problems via linear matrix inequalities (LMIs) with a linear equality constraint. Simulation studies illustrate that the proposed FIR filter is more robust against temporary uncertainties and has faster convergence than the conventional IIR filters.

In the post-modern society, creativity is redefined as a capability which collects a wide range of information and recombines them in diverse manners. With a such trend, the characteristics of collage - a method of making a creative image by combining pieces which have no relevance - is becoming prevalent in the post-modern culture. The purpose of this research is to develop a model which generates ideas in fashion design by use of collage techniques. With regard to research methodology, a literature survey was undertaken to find out and understand characteristics of collage. Analytic and positive studies were also done on the styles of fashion design of the 2003 SS collections to which collage techniques applied. In order to generate ideas in fashion design, the following mechanism using collage techniques can be used. Above all, pluralism is realized by collecting incoherent elements. Secondly, deconstruction is made by changing scales and configuration. Lastly, relativity is attained by using parts of ready-made goods and respecting their independency.
