The essence of architecture is space acquired as a result of architect's design act, but the object of the design is not the space and it is the physical elements to construct it. The masters of modern architecture have described the types of spaces that can be composed of these elements, but there is a difficulty in constructing the space because they does not mention how to construct it. From this point of view, if architecture is the techniques for human behavior and the art of building space, it is recognized that there is a need for concrete research on how to construct a space with ambiguous substance. Therefore, I conducted research on the extensibility of diagonal spaces through '4 Logements Studio' by Henri Ciriani, a representative architect of Neo Corbusian. The 'network for identity' method proposed by Ciriani was examined as a methode to realize spatial expansion and the furniture should be designed as an element of reading space and 3 optimal alternatives for 4 housing arrangements were obtained based on the Equivalence, Lighting, View, and Community life.

최근 한국 여름 기후의 열대화 현상이 급속화 됨에 따라 잦은 장마와 태풍으로 인해 방제 약품이 씻겨나가 방제가 제대로 안되는 경우가 많아졌다. 이는 식물과 작물들이 병해에 약해지는 계기를 만들었다. 따라서 본 논문에서는 그 중 실내 농사가 어려운 감귤에 중점을 잡고 감귤에서 주로 나타나는 흑점 영상 인식에 대한 모델을 제안하였다. HSV 공간으로의 변환과 LBP 기법을 통해 간단하지만 인식률을 높일 수 있는 방안을 마련하고자 했다. 자원과 계산을 효율적으로 사용하기 위해 모델을 간략화 하였으며 추후 스마트팜의 연구에 도움이 될 수 있을 것이라 기대한다.

There is a tremendous need for an effective indoor facility management since the building are tend to be built taller and bigger due to latest technology, Also, information that is continuously used and transferred during the design and construction phase is emerging due to 3D object-oriented CAD. Therefore, a system that will use such information for facility management should be developed. In this study, we present the methodology for definition the process that generates the Space Network Model automatically and examine the effective value of it.

In this paper, we proposed a method which predict the verb by using the neural network in order to enhance communication rate in augmentative communication system for Korean language disorders. Each word is represented by an information vector according to syntax and semantics, and is positioned at the state space by being partitioned into various regions different from a dictionary-like lexicon. Conceptual similarity is realized through position in state space. When a symbol was pressed, we could find the word for the symbol at the position in the state space. In order to prevent verb prediction's redundancy according to input units, we predicted the verb after separating class using the neural network. In the result we can enhance $20\% communication rate in the restricted space

위성화상 또는 항공사진을 이용하여 산화지를 탐지하고 정량화하기 위한 여러 가지 방법적인 시도가 있었다. 보다 정확한 산화지 탐지를 위해, 본 연구에서는 기존의 고해상도 범색화상과 중 저해상도 다중분광 화상의 융합(fusion)에 주로 이용되었던 IHS(Intensity, Hue, Saturation) 색채변환을 산화지 탐지와 정량화에 적용하였다. IHS 색채변환을 이용한 Hue 조합화상의 산화지 최대우도분류 결과는 Landsat-7 ETM+ 7:4:1 조합화상보다 놀은 사용자분류 정확도를 나타냈으며 색상(Hue)과 채도(Saturation)가 명도(Intensity)에 비해 ETM+ 화상의 분광특성을 잘 반영하였다.

The purpose of this study is to develop an index to measure regional creativity factors from previous research, as well as to empirically analyze the relationship between regional creativity and regional growth. We conduct panel analysis on the balanced panel data of regional creativity in fifteen Korean cities and provinces during 2008-2012. The result of hypothesis testing are as follows: First, amongst factors of regional creativity, sub-factors such as creative personnel and intangible asset (of the basic asset factor), creative enterprise (of the economic agent factor), and convergence and creative industries (of the core industry factor) showed significant influential relationships with GRDP (Gross Regional Domestic Product) as positive. Concerning the systemization factor, all sub-factors showed no significant relationship with GRDP. Second, amongst the factors, creative personnel (of the basic asset factor), start-up and entrepreneurship (of the systemization factor), creative enterprise (of the economic agent factor), the regional space factor, and convergence industry (of the core industry factor) showed significant positive relationships with employment rate. However, tangible and intangible creative asset (of the basic asset factor), convergence management and administration (of the systemization factor), Large/middle/small enterprises and central government/municipalities (of the economic agent factor), and creative industry (of the core industry factor) showed no significant relationship with employment rate. The results of this study will provide insight into the current situation for regional creativity, and review the process and short and long term performance. In addition, it will be a basic means to lead the central government's policy of strengthening local autonomy and decentralization.

In this paper we propose a new method of security visualization, VisFlow, using traffic flows to solve the problems of existing traffic flows based visualization techniques that were a loss of end-to-end semantics of communication, reflection problem by symmetrical address coordinates space, and intuitive loss problem in mass of traffic. VisFlow, a simple and effective security visualization interface, can do a real-time analysis and monitoring the situation in the managed network with visualizing a variety of network behavior not seen in the individual traffic data that can be shaped into patterns. This is a way to increase the intuitiveness and usability by identifying the role of nodes and by visualizing the highlighted or simplified information based on their importance in 2D/3D space. In addition, it monitor the network security situation as a way to increase the informational effectively using the asymmetrical connecting line based on IP addresses between pairs of nodes. Administrator can do a real-time analysis and monitoring the situation in the managed network using VisFlow, it makes to effectively investigate the massive traffic data and is easy to intuitively understand the entire network situation.

문화지도는 지도라는 인터페이스를 활용하여 문화와 관련된 여러 가지 주제들을 지도위에 나타내는 것이며, 이는 해당지역에 대한 문화(주제), 지역(공간), 시대(시간) 라는 세 가지 값을 동시에 활용하여 해당지역의 시대별 문화를 통합적으로 이해할 수 있다. 전자문화지도는 이러한 문화지도를 전자적 형태 즉, 컴퓨터를 활용해 구현한 시스템으로 주제, 공간, 시간 값의 메타데이터를 활용해 조합이 가능하도록 데이터베이스화한 개념이다. 이는 시대별 지역별 주제별 정보들을 사용자 스스로가 조합해서 조회가 가능하다는 의미이다. 본 논문에서는 해외지역, 특히 지중해지역 중심의 연구를 위한 전자문화지도를 설계한다. 이는 인문, 지역학과 IT의 융합학으로서, 해외지역을 연구하는 도구 및 연구결과물의 전시 도구로 활용할 수 있다.

As the use of smartphones become more common, the communication via instant messenger becomes natural. However, it is important to secure the relevant information promptly since the chat room between participants can be used as a space for a criminal conspiracy, and crime-related contents can be stored and deleted easily on smartphones. Therefore, this study aims to identify the available data and to use it as proof by comparing and analyzing the instant messengers with high usage rate.

일반적으로 딥러닝 기반의 객체 검출(Object Detection)기법은 합성곱 신경망(Convolutional Neural Network, CNN)을 통해 입력된 영상의 특징(Feature)을 추출하여 이를 통해 객체 검출을 수행한다. 최근 자연어 처리 분야에서 획기적인 성능을 보인 트랜스포머(Transformer)가 영상 분류, 객체 검출과 같은 컴퓨터 비전 작업을 수행하는데 있어 경쟁력이 있음이 드러나고 있다. 본 논문에서는 YOLOv4-CSP의 CSP 블록을 개선한 one-stage 방식의 객체 검출 네트워크를 제안한다. 개선된 CSP 블록은 트랜스포머(Transformer)의 멀티 헤드 어텐션(Multi-Head Attention)과 CSP 형태의 공간 피라미드 풀링(Spatial Pyramid Pooling, SPP) 연산을 기반으로 네트워크의 Backbone과 Neck에서의 feature 학습을 돕는다. 본 실험은 MSCOCO test-dev2017 데이터 셋으로 평가하였으며 제안하는 네트워크는 YOLOv4-CSP의 경량화 모델인 YOLOv4s-mish에 대하여 평균 정밀도(Average Precision, AP)기준 2.7% 향상된 검출 정확도를 보인다.
