Changes in society organization of rural villages in our country are caused by aging society and lessening of economic activity population aggravates the economy of rural villages. With this, it joins in with the aging of village community center, the representative center space of the rural village and therefore, it is a point of view where the change is necessary in the size and the side of function. The research which it sees is made on-the-spot inspection and literature investigation compensate in behalf of 25 administrative village community centers led in the object by grasping present status and drew up the layout sketches and plane surface degrees of the village community centers. By referring to the photographs and the topographical maps taken in the spot, it was able to divide the village community centers into side of arrangement, side of plane surface and side of form and managed to seize the characters, problems and improvable directions of each of them. The research result could be used as a guidable provision and be applied in the fundamental research in developing model of village community centers during space planning in the future.

The spatial property of contemporary library is now rapidly changing through the spatial expansion of knowledge and information, the reduction of information storing facility, the variation of approaching methods by digital shift and the transition of social recognition as a cultural facility. Also the spatial characteristics with referring characters have developed such as, decentralization, de-construction, de-boundary, individual space, erasing of boundary, flow of space which extends infinitely. The main process of library origination, the systematic classification, and the storage system concluding with the demand and value of the information by changing social demands and the role of the widest ranged facility. And 5 themes, such as, hierarchy, center, storage, boundary, and symbol, as a changed spatial concept and analyzed in the case of library plans and libraries which are actually built. The significant purpose of this research is to propose that rhizomatous intellectuality and hypertext could be a theoretical background of the contemporary architecture and could be a viewpoint of the transition of spatial structure in libraries. A future library should have spatial property embracing various social changes and needs and for this respect, it is necessary to approach and analyze through the architectural explication from diverging points of view.

The residential apartments have become a choice of a popular housing space since the first establishment of Mapo apartment in 1962. Therefore, the residential market experienced a bloom where residential apartments were sold as they were built simultaneously. However, this phenomenon was turned around and unsold lots appeared after the period of IMF and as the construction companies put out more various apartments by differing the characters and the strategies in building apartments. As a result, the leadership of residential market moved from the suppliers to consumers, in consequence, the wants of the consumers became more demanding. The consumer can freely control the number of rooms with a variable wall system or a bigger sized apartment with two entrances to the living room as well as having a bathroom with a master bedroom in a small-sized apartment. Many conceptual trials like this were taken to improve the residential environment and to give a change to the unit plan of the public housing. From these changes, one can observe a general trend that is taking place in current residential housing. Consequently, this study is on the type classification of unit plans in public housing built after 1999 and dwelled from 2001. The objectives of this study are to confirm the characteristics of the unit plans applied in recent public housing and provide basic materials that can be incorporated to residential space plan from now and hereafter.

In this paper, we studied on new method of recognition using structural information to recognize character pattern in orginal shape of Hangeul. First, for the purpose of knowing location of character in input image. it processed Making block. Second, after we investigated. whether vertical vowel exited or not in character image accordingly the center of gravity of Hangeul. each character was classified into Type of Hangeul by searching location and length for horizontal vowel and short pole. Last, we processed it by means of template matching which calculate Uclid's distance on each Jaso in accordance to type classified. This paper made an experiment on 2350 characters and obtained 98.3% classifing rate and 95.2% recognizing rate.

At the present time, the economy continues to flourish, and private cars have become the means of choice for most people. Therefore, the license plate recognition technology has become an indispensable part of intelligent transportation, with research and application value. In recent years, the convolution neural network for image classification is an application of deep learning on image processing. This paper proposes a strategy to improve the YOLO model by studying the deep learning convolutional neural network (CNN) and related target detection methods, and combines the OpenCV and TensorFlow frameworks to achieve efficient recognition of license plate characters. The experimental results show that target detection method based on YOLO is beneficial to shorten the training process and achieve a good level of accuracy.

Recent phylogenetic studies of scytosiphonacean brown algae show many conflicts with current classification. In order to clearly define the phylogenetic relationships of the family, we newly sequenced the photosystem I coding psaA gene (1488 base pairs) from 13 taxa (15 samples), of the family, and, for comparison, rbcL from four taxa. The psaA region has more informative sites (17.9%) than the rbcL (13.1%) and the number of nodes supported by over 50% bootstrap values is more in the psaA phylogeny (53 /57 nodes; 93%) than in the rbcL (47/63 nodes; 74.6%). The psaA phylogenies are basically congruent with the rbcL trees, recognizing two major groups in the monophyletic Scytosiphonaceae. The first group included Myelophycus, Petalonia, Scytosiphon, and elongate sack-shaped species of Colpomenia, primarily cold temperate elements with unilocular zoidangia on sporophytes. The second group, although not resolved, consisted of Hydroclathrus, Chnoospora, Rosenvingea, and ball-shaped Colpomenia, primarily warm-temperate taxa with both unilocular and plurilocular zoidangia on sporophytes. Chnoospora is not monophyletic, as was previously shown the paraphyly of Colpomenia, Petalonia, and Scytosiphon. Hydroclathrus clathratus from Korea and Japan was not monophyletic. Our studies show that gametophytic characters are the main source of conflict for the present taxonomy of the family. The psaA region is a useful tool for resolution of phylogenetic relationships within the Scytosiphonaceae.

While recognition of isolated units of writing, such as a character or a word, has been extensively studied, emphasis on the segmentation itself has been lacking. In this paper we propose an active segmentation method for handwritten Hangul address strings based on the Run-length code. A slant correction algorithm, which is considered as an important preprocessing step for the segmentation, is presented. Three fundamental candidate estimation functions are introduced to detect the clues on touching points, and the classification of touching types is attempted depending on the structural peculiarity of Hangul. Our experiments show segmentation performance of 88.2% on touching characters with minimal over-segmentation.
