최근 멀티코어 프로세서의 활용이 대중화되고 있다. 멀티코어 시스템에서는 소프트웨어가 동시에 여러 코어를 사용하여 동작을 수행 할 때 성능 향상 효과를 얻을 수 있다. 즉, 하나의 소프트웨어가 여러 코어를 동시에 사용할 수 있는 멀티스레드 프로그래밍 기법을 사용할 때 성능을 높일 수 있다. 이러한 환경에서 효율적인 메모리 할당은 데스크톱, 서버 및 과학 등과 같은 응용에 매우 중요하다. 하지만, 동적으로 메모리를 할당하는 것은 메모리 할당 연산과 반환 연산 및 어떤 스레드가 다른 스레드의 힙 영역에 접근하는 것을 처리하기 위한 동기화 문제로 인한 오버헤드가 발생하여 성능에 영향을 끼치는 문제가 발생하게 된다. 따라서 이와 같은 환경에서 실제로 성능에 어느 정도 영향을 끼칠 것인가를 측정할 수 있는 도구가 필요하다. 이에 멀티코어 환경에서 멀티스레드 기법을 사용하여 메모리 할당 연산이 성능에 어떠한 영향을 끼치는지를 측정 및 평가할 수 있는 시뮬레이터인 MAES(Memory Allocation Evaluation Simulator)를 설계하고 구현한다.

20th century was the age of Modernism which was based on rational side of human mind. However, with the fall of Modernism, also came the fall of rationalism's dictatorship. Now, we see the pursuit and quest of irrational thinking as a new possibility of human expression which actually was already begun by Dada and Surrealism in early 20th century. It was facilitated by re-evaluation of Freud's psychoanalytic theory at the end of 20th century. This paper researches psychoanalytic approach applied to the analyses of unconscious human desires in art and design, especially its application to contemporary space design. These designs represent, without making any ethical evaluation, the fact that those unconscious desires are part of inborn human nature and the fact that 21st century is heading toward open society which embraces diverse values and possibilities. By analyzing irrational tendencies in contemporary space designs, this paper aims at proving the meaning and value for one of new directions in 21st century space design. First chapter is an introduction. Second chapter studies Freud's psychoanalytic theory. Third chapter examines the psychoanalytic methodologies with which unconscious desires are expressed in art and design. Fourth chapter classifies the types of subconscious desires expressed in contemporary space designs and analyzes their case studies. Fifth chapter is the conclusion.

Software measurement is a key factor in managing, controlling, and improving the software development processes. Software quality is one of the most important factors for assessing the global competitive position of any software company. Thus the quantification of quality parameters and integrating them into quality models is very essential. Software quality criteria are not very easily measured and quantified. Many attempts have been made to exactly quantify the software quality parameters using various models such as ISO/IEC 9126 Quality Model, Boehm's Model, McCall's model, etc. In this paper an attempt has been made to provide a tool for precisely quantifying software quality factors with the help of quality factors stated in ISO/IEC 9126 model. Due to the unpredictable nature of the software quality attributes, the fuzzy multi criteria approach has been used to evolve the quality of the software.

Purpose: The purpose of this study was to investigate the relationships of ego-resilience, stress coping styles and disposition to delinquency in middle school students. Method: The data were collected from October 15 to October 30, 2005. The subjects were 223 middle school students in 2nd grade in G city. To determine the most effective variable of ego-resilience to stress coping styles and disposition to delinquency, the dada were analyzed using Canonical correlation with SAS 9.1 TS, and Pearson's correlation with percentages, means, standard deviations with SPSS 14.0 K. Result: Ego-resilience showed a significant positive correlation with active coping styles and a significant negative correlation with passive coping styles, and disposition to delinquency. Canonical correlation analysis of 5 sub-domains of ego-resilience showed that curiosity made the highest contribution to predicting stress coping styles and vitality made the highest contribution in predicting disposition to delinquency in middle school students. Conclusions: The results of this study suggest that the development of ego-resilience for adolescents is important to improve stress coping strategies and decrease delinquency. Therefore, to increase ego-resilience, Stress Coping Programs should include curiosity and Delinquency Intervention Programs should include vitality.

The historicism and romanticism of John Galliano's designs are rivaled only by the spectacular and theatrical nature of his fashion shows; romantic silhouette, the complexity of the cut and, of course, the painstaking attention to historical detail. Galliano's approach is very much that of a British designer in that he absorbs wildly diverging historical and cultural elements to invent new hybridizations of the contemporary. Galliano started his career as part of the wildly uninhibited avant-garde London design scene. His designs were twisted and artfully torn, weired and also beautiful. The purpose of this study is to investigate the Comic Expression depicted on John Galliano's works by borrowing the Comic. The Comic or the Comedy is a kind of art form that signifies exciting effects, and so, is a means of raising a laugh. The similar concepts of the Comic already were depicted by means of transformation and distortion of form, satire, fantastic pastiche and reversion of substances on Cubism, Dada, Surrealism, Pop Art and Postmodernism. Therefore, John Galliano selected the quixotic expressional methods to seek for having playful fun. The aesthetics of the Comic is the beauty based on quantitative or qualitative contradiction between expectations and realizations. That is, the Comic is characterized by getting rid of stress through laugh with clarifying a subject of contradiction. This study found that John Galliano's designs are expressed the quixotic comic on Historical image, Exotic image and Primitive image to make a complaint against the social evils.

The anticarcinogenic effects of dimethyl disulfide(DMDS, methyl disulfide)and diallyl disulfide(DADA, allyl disulfide) were studied in a 28 weeks rat multi-organ carcinogenesis model. neoplastic and preneoplastic lesions were observed in the liver kidney thyroid gland esophagus duodenum colon, rectum and adrenal gland. Tesults showed that neoplastic lesions in the kidney liver and thyroid gland were inhibited by DADS but those in the liver and colon were enhanced by DMDS when compared to positive control group. incidence of neoplastic lesions in the other organs were not changed by DMDS or DADS exposure. While GST-p positive foci in the liver were increased by DMDS, DADS had no effect. There was no significant histopathological lesion in DMDS or DADS treated group without pretreatment with carcinogens.

This study aims to figure out any possible expanded expression methods and diverse formative effects in fashion design by recognizing the importance of objects that suggest new paradigms as a means of expressing aesthetic consciousness in contemporary fashion and analogizing the formative characteristics of objects used in fashion and their significance. Accordingly, the study focuses on analyzing and interpreting objects introduced to fashion design with a formative view by substituting the concept of an object that has taken an important position in the contemporary arts for fashion. This study further aims to examine the concept of objects by trend and their characteristics within a syntactical structure and come up with a standard for classification of objects and a framework of analysis from cubism in the early 20th century when the concept of an object began to appear in arts to Dadaism, Surrealism, Pop art, Land art, Environmental art and the present time. Finally, the study aims to examine the status of objects in fashion and the relationships between fashion and objects through analyses on fashion objects and to suggest new perspectives and approaches to interpret the contemporary fashion in the 21st century.

A video analysis system used to detect events in video streams generally has several processes, including object detection, object trajectories analysis, and recognition of the trajectories by comparison with an a priori trained model. However, these processes do not work well in a complex environment that has many occlusions, mirror effects, and/or shadow effects. We propose a new approach to a context-aware video surveillance system to detect predefined contexts in video streams. The proposed system consists of two modules: a feature extractor and a context recognizer. The feature extractor calculates the moving energy that represents the amount of moving objects in a video stream and the stationary energy that represents the amount of still objects in a video stream. We represent situations and events as motion changes and stationary energy in video streams. The context recognizer determines whether predefined contexts are included in video streams using the extracted moving and stationary energies from a feature extractor. To train each context model and recognize predefined contexts in video streams, we propose and use a new ensemble classifier based on the AdaBoost algorithm, DAdaBoost, which is one of the most famous ensemble classifier algorithms. Our proposed approach is expected to be a robust method in more complex environments that have a mirror effect and/or a shadow effect.
