On the recent, Architecture markets appeared new eyes about Architecture. 'Korea Young Architect Award' organized by the 'Ministry of Culture, Sports and Tourism' is the right. The award in this age or in the near future we will meet down the building appear to have opinions about. 2008 to 2012, a group of 21 architects or architectural groups were selected. And they are active to this day. This study analyzes the following four indicators for architects throughout the new ideas and would like to provide feedback on them. And this study is estimated to direction of development and Forecasting of the construction First, Young Architect of the thinking process and practice analysis of the direction of watch. I think they want to, and philosophy, practice and methods that will be discussed. Second, If you assume that these architects in Korea when new, they are compared with the existing architects how diverse, and how about that discriminatory practices and examines. Third, Not only in Korea but also targeted at young architects in the United States, one organized by the Architectural League of New York 'Architectural League Prize for Young Architects' have been awarded. This group of four architects selected as Korea becomes, which of them through the research architect Yang sooin architects in the United States, you want something new will be discussed. Finally, Similar to those in the past, architects Guess watch. Find out about and how different.

This paper is to find out the reason why students often make mistakes with 0 during computation and to get some instructional implication. For this, history of 0 is reviewed and mathematics textbook and workbook are analyzed. History of 0 tells us that the ancients had almost the same problem with 0 as we have. So we can guess children's problems with 0 have a kind of epistemological obstacles. And textbook analysis tells us that there are some instructional problems with 0 in textbooks: method and time of introducing 0, method of introducing computational algorithms, implicit teaching of the number facts with 0, ignoring the problems which can give rise to errors with 0. Finally, As a reult of analysis of Japanese and German textbooks, three instructional implications are induced:(i) emphasis of role of 0 as a place holder in decimal numeration system (ii) explicit and systematic teaching of the process and product of calculation with 0 (iii) giving practice of problems which can give rise to errors with 0 for prevention of systematical errors with 0.

Digital Rights Management(DRM) is a term that refers technologies for imposing limitations on the use of digital content for protecting media copyright holders. This paper proposes a generic scheme for digital media copy protection that can be applied to any digital media such as audio, video, etc. The scheme will make it very hard to play a copied content on a foreign platform and to guess secret content encryption keys. Unlike other DRM techniques, the scheme uses the stream cipher HC-256 only for encrypting media content and it allows a client to start content playback immediately following its streamed decryption. As to the encryption, it requires to generate several secret keys for each new client(player copy), rather than for each media content, which makes it scalable in terms of managed keys. Also, for simplicity, the scheme supports the popular unlimited-play-after-download policy only, which would eliminate the necessity for deploying separate server or process for licensing.

The object of this paper is to make learners have study environment to study adaptively, anywhere, anyone, anytime and, just in time, not disturbed by time and place. So, it helps learners find solutions to questions and problems which they can face in the process of learning. This paper desires to find possibility of ontology which can solve problems after considering semantic web and theory of ontology by studying existing reference books. As ontology has the structure that can guess the data which is not showed clearly, so it can make the result more accurate and be the knowledge every learner sympathize and trust. I established the ontology frame about the electronic circuit which learners can solve their questions everywhere, anytime, and reconfirm what they studied, so I studied on application for e-learning based on ontology.

The emergence of the automated smart grid has become an essential device for responding to these problems and is bringing progress toward a smart grid-based society. Smart grid is a new paradigm that enables two-way communication between electricity suppliers and consumers. Smart grids have emerged due to engineers' initiatives to make the power grid more stable, reliable, efficient and safe. Smart grids create opportunities for electricity consumers to play a greater role in electricity use and motivate them to use electricity wisely and efficiently. Therefore, this study focuses on power demand management through machine learning. In relation to demand forecasting using machine learning, various machine learning models are currently introduced and applied, and a systematic approach is required. In particular, the GP learning model has advantages over other learning models in terms of general consumption prediction and data visualization, but is strongly influenced by data independence when it comes to prediction of smart meter data.

This thesis aims to study Change of the Land Use in Yanji city since the reformation and opening of China in the Connection with Urbanization Process. This study is based on Landsat image and maps and data related to topography, urban planning basic, the cadastral map were employed. Softwares such as Arcview3.3, ArcGis8.0 were used. The result of the research is as follows. It clearly appears that there have decreased in the ratio of agricultural areas since the increase in other urban usage of land. There has greatly increased in residential, commercial and industrial areas. Such as the capitalist and market economic city the highest point of city land price emerged in downtown of the old city center. In addition spatial pattern of land price is unusually quite different from the western city in its pattern of land price surface declining tendency between the highest land price and the lowest land price. The land price surface shows irregular patterns with increase of distance from downtown due to various urban developments. According to the land price distribution map, it is possible to guess spatial development of the city that the north-eastern part of Yanji was developed prior to south-western area. The center of the city, or downtown expanded to eastward, and the city expanded to south-westward out skirt. Along the main road, Xin-xing areas developed toward east and west ward.

Recently, Software Development was applied to new-approach methods as a various form : client-server system and web-programing, object-orient concept, distributed development with a network environments. On the other hand, it be concerned about the distributed development technology and increasing of object-oriented methodology. These technology is spread out the software quality and improve of software production, reduction of the software develop working. Futures, we considered about the distributed software development technique with a many workstation. In this paper, we discussed optimal release problem based on a stochastic differential equation model for the distributed Software development environments. In the past, the software reliability applied to quality a rough guess with a software development process and approach by the estimation of reliability for a test progress. But, in this paper, we decided to optimal release times two method: first, SRGM with an error counting model in fault detection phase by NHPP. Second, fault detection is change of continuous random variable by SDE(stochastic differential equation). Here, we decide to optimal release time as a minimum cost form the detected failure data and debugging fault data during the system test phase and operational phase. Especially, we discussed to limitation of reliability considering of total software cost probability distribution.

Objectives: This study was carried out to observe the foot gworeum meridian muscle from a viewpoint of human anatomy on the assumption that the meridian muscle system is basically matched to the meridian vessel system as a part of the meridian system, and further to support the accurate application of acupuncture in clinical practice. Methods: Meridian points corresponding to the foot gworeum meridian muscle at the body surface were labeled with latex, being based on Korean standard acupuncture point locations. In order to expose components related to the foot gworeum meridian muscle, the cadaver was then dissected, being respectively divided into superficial, middle, and deep layers while entering more deeply. Results: Anatomical components related to the foot gworeum meridian muscle in human are composed of muscles, fascia, ligament, nerves, etc. The anatomical components of the foot gworeum meridian muscle in cadaver are as follows: 1. Muscle: Dorsal pedis fascia, crural fascia, flexor digitorum (digit.) longus muscle (m.), soleus m., sartorius m., adductor longus m., and external abdominal oblique m. aponeurosis at the superficial layer, dorsal interosseous m. tendon (tend.), extensor (ext.) hallucis brevis m. tend., ext. hallucis longus m. tend., tibialis anterior m. tend., flexor digit. longus m., and internal abdominal oblique m. at the middle layer, and finally posterior tibialis m., gracilis m. tend., semitendinosus m. tend., semimembranosus m. tend., gastrocnemius m., adductor magnus m. tend., vastus medialis m., adductor brevis m., and intercostal m. at the deep layer. 2. Nerve: Dorsal digital branch (br.) of the deep peroneal nerve (n.), dorsal br. of the proper plantar digital n., medial br. of the deep peroneal n., saphenous n., infrapatellar br. of the saphenous n., cutaneous (cut.) br. of the obturator n., femoral br. of the genitofemoral n., anterior (ant.) cut. br. of the femoral n., ant. cut. br. of the iliohypogastric n., lateral cut. br. of the intercostal n. (T11), and lateral cut. br. of the intercostal n. (T6) at the superficial layer, saphenous n., ant. division of the obturator n., post. division of the obturator n., obturator n., ant. cut. br. of the intercostal n. (T11), and ant. cut. br. of the intercostal n. (T6) at the middle layer, and finally tibialis n. and articular br. of tibial n. at the deep layer. Conclusion: The meridian muscle system seemed to be closely matched to the meridian vessel system as a part of the meridian system. This study shows comparative differences from established studies on anatomical components related to the foot gworeum meridian muscle, and also from the methodical aspect of the analytic process. In addition, the human foot gworeum meridian muscle is composed of the proper muscles, and also may include the relevant nerves, but it is as questionable as ever, and we can guess that there are somewhat conceptual differences between terms (that is, nerves which control muscles in the foot gworeum meridian muscle and those which pass nearby) in human anatomy.

Chinese medical materials of Astragalas manbranaceus Bunge, Angelica gigas Nakai, Cnidium officinale, Glycyrrhiza uralensis Fisch, Lycium Chinese Mill were mixed, mixing ratio was 28:20: 18:18:16(w/w). Yield and concentration of extract obtained through extraction- concentration process of the mixed Chinese medical materials were 37.28%(w/w) and 50Brix, respectively. Animal feed(AF) used for animal test was manufactured from both mixing of general AF and this extract(0∼ 5%, w/w) and freeze dried. After the male rats were fed experimental diets in order to test during 4 weeks, the results of plasma TG, total cholesterol, phospholipid content changes and plasma, pancreas and femur insulin concentration changes were followed. The more the amount of treatment of Chinese medical material extract are, the higher the effect of concentration decline are in plasma lipid concentration. And at 3% treatment plasma TG, total cholesterol and phospholipid contents are decreased respectively 8.62%, 2.81% and 2.11%. Plasma glucose concentration has also similar effect that those things are decreased at 3% treatment. Insulin concentration of plasma, pancreas and femur are difficult to prove the effects due to respective increase and decrease. We guess that these results comes from not experimenting intentioned rat of diabetes mellitus but normal rat.
