RNA 분자의 이차 구조를 예측하고 예측된 구조를 분석, 평가하기 위하여 시각화하는 작업은 RNA의 구조에 대한 연구에 있어서 가장 필수적인 과정이다. 본 논문은 이차 구조를 시각화하는 알고리즘과 이를 구현한 프로그램을 소개한다. 이 알고리즘은 vector와 vector space를 이용하여 RNA 분자의 구조 요소가 배치될 방향과 공간을 나타낸다. 구조 요소가 겹치지 않도록 배치될 방향과 공간을 효율적으로 찾기 위하여, 구조 요소를 배치하는 순서에 관한 휴리스틱과 구조 요소를 배치하는 방법에 관한 휴리스틱을 사용한다. 기존의 시각화 알고리즘이 구조요소를 순차적으로 배치하면서 겹침 현상이 발생하면, 이를 제거 하기 위하여 이미 배치한 구조 요소들을 재배치 하거나 변형하는 것에 반하여, 이 알고리즘은 사용자의 판단이나 수작업에 의존하지 않고 겹침 현상이 거의 없는 이차 구조를 효율적으로 생성한다는 점에서 기존 방법을 많이 개선하였다.

최근 상품의 특성을 고려하지 않은 박스 크기 선택과 박스 공간 내 비효율적인 상품 배치로 인하여 박스의 파손 문제가 지속적으로 제기되고 있다. 이는 적재하고자 하는 상품의 특성을 고려하지 않고 상품을 대략적으로 배치하기 때문이다. 따라서 본 논문에서는 면적과 무게와 같은 상품의 특성을 고려한 상품 배치 최적화 알고리즘을 제안하여 공간 배치의 비효율성 문제를 최소화하고자 한다. 제안한 상품 배치 최적화 알고리즘은 검색 트리 (search tree)와 상품 특성 기반 평가 함수(evaluation function)로 구성되어 있다. 상품 특성 기반 평가 함수는 면적, 무게 및 바닥에 닿는 면적을 고려하여 설계되었다.

In this paper, we proposed an optimization technique for efficiently placing vehicles on decks in a vehicle-carrying ship to efficiently handle loading and unloading. For this purpose, we utilized the transformation method of the XML data representing the ship's spatial information, merging and branching algorithm and genetic algorithm, and implemented the function to visualize the optimized vehicle placement results. The techniques of selection, crossover, mutation, and elite preservation, which are used in the conventional genetic algorithms, are used. In particular, the vehicle placement optimization method is proposed by merging and branching the ship space for the vehicle loading. The experimental results show that the proposed merging and branching method is effective for the optimization process that is difficult to optimize with the existing genetic algorithm alone. In addition, visualization results show vehicle layout results in the form of drawings so that experts can easily determine the efficiency of the layout results.

Simgok Seowon was established to honor Jo Gwang-jo, who is a scholar and politician in the mid-Joseon period. It is located in a propitious site based on Feng Shui. Its Jusan is Mugokeumseongchae(武曲金星體) with Wonhwahyul(圓窩穴), and its Ansan is Tamrangmokseongchae(貪狼木星體). It is a Jehyang(祭享)-centered Seowon that sets a Jehyang place in Hyeolcheo. Around the Sadang(祠堂), the Four gods including Jwacheongryong(左靑龍) Woobackho(右白虎), Jujak(朱雀), and Hyeonmu(玄武) protect the Hyeolcheo(穴處) well. It is a typical central axis symmetrical spatial arrangement where everything is located centered on Sawoo(祠宇). It is a type of Jeonhakhumyo(前學後廟) that arranges the main hall at the front of buildings and places the Sadang that is a Jehyang place at the back of Sadang. To the left side of the Sadang, Yeonji(蓮池) was created by applying the principles of Cheonwonjibang(天圓地方), which serves as Yusik(遊息) area with functions to adjust microclimate and to extinguish fires. Feng Shui plays an important role when determining orientation, direction, and location of the buildings. Therefore, it could be regarded as realizing the aesthetic spirit of Cheoninhabil(天人合一) to compose the Feng Shui-oriented spatial arrangement by recognizing accurately the relationship between nature and human being depending on topography, wind, water flow, and point of the compass.

The purpose of this study is to make planning factors for outdoor space in elementary school site, with analyzation focusing on a Japanese elementary school examples. We evaluated the planning factors which encourage the development of children’s behaviors from quality of space. And we can get the important points as planning factor for school site as follows: 1) The base point of zoning is school building, building entrance, entrance of site and track 2) The importance of linked space plan with inside of site and surrounding environment 3) Preservation linked system of space in school site for linked pattern of child’s behavior.

Space planning is one of the popular applications of VR technology including interior design, architecture design, and factory layout. In order to provide easier methods to accommodate physical objects into virtual space planning task, we suggest applying mixed reality (MR) interface. We describe our hardware and software of our MR system designed according to requirements of the application domain. In brief, our system hardware consists of a video see-through display with a touch screen interface, mounted on a mobile platform, and we use screen space 3D manipulations to arrange virtual objects within the MR scene. Investigating the interface with our prototype implementation, we are convinced that our system will help users to design spaces in more easy and effective way.

According to the changes in society, the knowledge industrial center, which is a factory related to the manufacturing industry, is now including various programs, such as information and communication knowledge. This study defined the knowledge industrial center related law into three periods: deduct layout planning type and outside space composition elements by previous research; case analysis; and suggestions of the direction of layout planning and outside space plan. As a result of the analysis, first, before 1999, the layout of the building is made mainly with a car, but depending on the form of the site, it is configured as a centered, side layout. Second, in the case of distribution, the support facility on the lower part is integrated and the factory on the higher part is distributed, so it is partly integrated and the building is unified. Third, beginning with the activation of privately owned public space in a semi-industrial district according to architecture regulations in 1999, the outside space is wider but the construction area is reduced, so the outside space composition has been changing in a similar manner to the planning methods of business facilities, such as office buildings.

When it comes to the paintings in Joseon Dynasty, landscape and a genre paintings were popular but it was Minhwa that people of every dass loved. Minhwa contained not only true meaning of a picture, but also it was simple and straighforwardly depicted. Among them, paintings in books belonging to the Joseon Dynasty (hereinafter called Checkgeori paintings) describe a small universe in which people live harmoniously in nature on the basis of a Confucian society. In addition, it shows modern philosophy in paintings and makes a feature of human life. In this paper, 'Ssangpok Checkgeori 'in Checkgeori paintings illustrates the relationships between things such as color, arrangement, place and direction. They have outstanding features such as the direction of things in composition, multiple vanishing points, a folding screen constituent and movement of viewpoints. Therefore, we come to know the painting method of 'Ssangpok Checkgeori' can be applied to modern paintings.
