  • The Von Neumann based architecture of the modern computer has dominated the computing industry for the past 50 years, sparking the digital revolution and propelling us into today's information age. Recent research focus and market trends have shown significant effort toward the advancement and application of artificial intelligence technologies. Although artificial intelligence has been studied for decades since the Turing machine was first introduced, the field has recently emerged into the spotlight thanks to remarkable milestones such as AlexNet-CNN and Alpha-Go, whose neural-network based deep learning methods have achieved a ground-breaking performance superior to existing recognition, classification, and decision algorithms. Unprecedented results in a wide variety of applications (drones, autonomous driving, robots, stock markets, computer vision, voice, and so on) have signaled the beginning of a golden age for artificial intelligence after 40 years of relative dormancy. Algorithmic research continues to progress at a breath-taking pace as evidenced by the rate of new neural networks being announced. However, traditional Von Neumann based architectures have proven to be inadequate in terms of computation power, and inherently inefficient in their processing of vastly parallel computations, which is a characteristic of deep neural networks. Consequently, global conglomerates such as Intel, Huawei, and Google, as well as large domestic corporations and fabless companies are developing dedicated semiconductor chips customized for artificial intelligence computations. The AI Processor Research Laboratory at ETRI is focusing on the research and development of super low-power AI processor chips. In this article, we present the current trends in computation platform, parallel processing, AI processor, and super-threaded AI processor research being conducted at ETRI.

  • During the past five years a very successful effort has been made to improve existing and develop new aluminium alloys. The progress achieved has been possible because of the development of new production methods, such as powder metallurgy and spray/deposition. These methods make use of rapid solidification process which alloys compositions other than those achieved by conventional ingot metallurgy. The ingot metallurgy of the 2000 and 7000 series used thus far, as well as the age hardening Al-Li alloys, show several disadvantages caused by the production process. Such problems are primarily coarse intermetallic constituent phases, coarse grains and macrosegregation, resulting in low fracture toughness. The present contribution reports results of an experimental investigation performed on a modern high strength spay deposited aluminium alloy of the Al-Zn-Mg-Cu (7075 and the modified 7150X) type. Results are given in terms of its microstructural characterization by using X-ray diffractomertry and transmission electron microscopic. The mechanical propierties of those alloys in the as-extruded and extruded+aged condition were evaluated by using microhardness Vickers, tensile test and fracture toughness measurements.

  • In the age of knowledge and information when every aspect of economy, education and culture in society is changing rapidly, the teacher is not just a provider of knowledge in classroom. Ultra-modern educational tools and materials have come into being with the latest developments in science and technology and we see classroom teaching in general tending towards more 'open' classroom and study. What the students need most for the coming century is the cultivation of higher faculties such as creative thinking, the power to solve problems, and the spirit of inquiry. The present-day teacher is required to make use of various teaching medial in order to provide the students with better educational environment for developing these faculties, not the teaching method of the past with the teacher at the center. One way to enhance classroom environment is in reintroducing the modernized teacher's desk to the center of teaching apparatus. This paper is about the better way of designing the teacher's multimedia desk equipped with a PC that will make it possible for the teacher to utilize the internet-based educational resources.

  • The Earth is exposed to constant outflow of the solar wind from the outer layers of the Sun, and violent transient events taking place from active regions increase the energy flux of both radiation and particles leaving the Sun. Thus the space surrounding the Earth is a highly dynamic environment that responds sensitively to changes in radiation, particles and magnetic field arriving from the Sun. Nowadays, it becomes increasingly important to understand how the physical system of Earth-space works and how the space around the Earth connects to interplanetary space. In the present paper we describe how explosive solar events, such as CME(Coronal Mass Ejection) and flares affect the Earth-space environment and how the space weather reacts to them. Practical consequences are presented to demonstrate why a broader view of Earth's environment is greatly needed to cope with modern day's inhabitation problem in a rapidly developing space age.

  • Towards the second half of 20th century the fashion market has become increasely fragmented reflecting the pluality of cultures. As a result style no longer had time to accrue individuality and so people lost interest. In the aftermath of this fashion has turned its atten-tion to its materials for inspiration and inno-vation. Taking their inspiration for new working designers have began to explore diverse materials and expressive techniques of tex-ture. Textural expression can change the im-age of a garment even on with the same structural design. This study is to present the crinkle express-ive technique of texture through the applied examples in contemporary fashion and related backgrounds. The result of this study testified the import-ance of texture as plastic element through various techniques of crinkle; 1) creasing technique is reminiscent of the delphos of Fortuny by modern materials 2) twisting tech-nique is that finished garment is twisted and crumpled by hand 3) shirnking technique is recreated method that is crushed and tied for granting the human touch to the material.

  • This thesis is concerned with military officer's uniform system in Ko-Jong and Soon-Jong dynasties (1964∼1910) in the end of Korean Dynasty. especially, the most important study in this thesis is as follows. First, the change and the motivation of military officer's uniform system and the background of the days are surveyed. Second, is have compared with the royal article that made military officer's uniform system change. Third, I have compared with military officer's uniform formation and surveyed military officer's uniform system to the days. the military uniform in the period of Ko-Jong Dynasty was Europeanized. namely, it was the period that the modern military uniform was adapted, putting away Koo military uniform system to have wore "Dongtali" and"Bungguzi", studing the uniform system in those days will be connected with a civilized age and the present day directly. Therefore I have surveyed military officer/s uniform system, mainly in the army uniform system.

  • The study is motivated by methodological approach on how to apply the existing traditional placeness to the present age. Moreover, its purpose lies in establishment of character of place that not only embraces the existing meaning of place but also reflects on the new paradigm of space through culturenomics which embraces the core indexes of modern values such as economics, culture, and everything. Culture has a potential to create various values through its convergence with other fields, one of which is place. Place is essentially an original center of human existence. Culture is no more separated from daily life and people's way of life becomes a culture. In the a culture-oriented social system, design of place will be developed in a multi-dimensional way that accepts diversity and centers on relation. At our places experiencing placelessness through uniformity and modernization, this study has a significant meaning since it shows culturenomics may offer a solution to the direction of growth in the future.

  • Constraining physical (or stellar population) properties - such as stellar mass, star-formation rate, stellar population age, and dust-extinction - of galaxies from observation is crucial in the study of galaxy evolution. This is very challenging especially for high-redshift galaxies, and a widely-used method to estimate physical properties of high-redshift galaxies is to compare their photometric spectral energy distributions (SEDs) to spectral templates from stellar population synthesis models. I will show that the SED-fitting results of high-redshift galaxies are strongly dependent on the assumed forms of star-formation histories. I will also present the results of SED-fitting analysis of observed Lyman-break galaxies which show that parametric models with gradually increasing star-formation histories provide better estimates of physical parameters of high-redshift (z>3) star-forming galaxies than traditionally-used exponentially declining star-formation histories. This result is also consistent with the predictions from the modern galaxy formation models.

  • The purpose of this study was to research and design stage costumes of Whangjinie focusing on inner image of Whangjinie, present stage costumes of new image. Four steps were taken in order to achieve this purpose. The first step was to investigate the old documents and prior research about literature world of Whangjinie. The second step was to analyze stage costumes of Whangjinie which were worn in opera, movie. The third step was to design and make the stage costumes according to new images Whangjinie which were extracted from above two research results. The new images of Whangjinie are as follows 1. Whangjinie as a kisaeng(professional entertainer) She thirsted for new, materialistic love though she failed in love everytime. 2. Whangjinie as a woman. She had a hard time by feeling an irresistible yearning for lover 3. Whangjinie as a poet. She expressed as a poetry her vanity and loneliness of life. Using above three images, this study designed four new stage costumes of Whangjinie and two designs of them were made really. But this study didn't present historic costume of her age but expressed modern mood in color and form.
