In the path traveling of differential-drive robots, the steering controller plays an important role in determining the path-following performance. When a robot with a pure-pursuit algorithm is used to continuously drive a right-angled driving path in an unstructured environment without turning in place, the robot cannot accurately follow the right-angled path and stops driving due to the ground and motor load caused by turning. In the case of pure-pursuit, only the current robot position and the steering angle to the current target path point are generated, and the steering component does not reflect the speed plan, which requires improvement for precise path following. In this study, we propose a driving algorithm for differentially driven robots that enables precise path following by planning the driving speed using the radius of curvature and fusing the planned speed with the steering angle of the existing pure-pursuit controller, similar to the Model Predict Control control that reflects speed planning. When speed planning is applied, the robot slows down before entering a right-angle path and returns to the input speed when leaving the right-angle path. The pure-pursuit controller then fuses the steering angle calculated at each path point with the accelerated and decelerated velocity to achieve more precise following of the orthogonal path.

A thesis presented on the study of visitors circulation character, and components in an exhibition space in museums. A behavior ethogram is an investigational tool of tracing examination of visitors. An exhibition layout and behavior characters of exhibition viewing in the configuration of exhibition space are planned by using the method of the behavior ethogram. As time goes by an expansion of a museums concept and changing roles are more extroversive and constructive than the past. It will reflect the phases of the times and show several different aspects. The reflection of the changing circumstance will have to examine an each relationship between exhibition data, exhibition spaces and visitors In the beginning of a plan of the museum. However, the study of a unique behavior pattern and character which are made by moving visitors themselves are quietly not enough studied. The exhibition layout which is considerably examined by the viewing behavior of visitors in act response and a following circulation of viewing have a lack of precise directions and examples. In short, this study ultimately represents to grasp the meaning of the behavior characters of viewing. Furthermore, the basic directions in the museums plan are carefully considered by the reflection of exhibition circulation.

This paper aims to describe a case study of parametric interior design based on BIM (Building Information Modeling). As the practical use of BIM-based design grows, its influence expands into the field of interior architecture design. BIM makes possible to check various design plan, reach decision making in an effective way, and change design plan in an efficient method. Therefore, BIM is also promising field in interior architecture design. However, compared to other fields in architecture, engineering, and construction (AEC) industry, there have been less research and projects on BIM in the field of interior architecture. For increasing the feasibility of adapting BIM in interior architecture design, this paper describes a case study-projecting images for designing interior panels using parametric modeling. This process needs elaborate, delicate, and precise steps for harmonious output. For continuous use of building, users look forward to the design which variable and changeable according to user's preference and environment. Therefore, demand for parametric design in the interior design part such as panel pattern design for various decoration is growing. Treated process in this paper deals with an advanced phase which much effective in decreasing time consumption and useless part of process. Finally, this paper suggests the possibility of using BIM in the interior design process and field where BIM can be applied.

University campuses, in Korea, experienced expansion during the 1970's and exceeded its capacity in the 1980's. On the other hand, universities needed to deal with increasing capacity and expansion of its facilities. This study is carried out in three steps : developing the factors of environmental friendly assessment, designing an assessment table based on specific categories, and applying the categories to the campus of Seoul National University. The assessment factors and assessment table were designed through a survey of experts in landscaping, architecture, and urban planning. The elements of major categories were classified as follows; 1) Management of land and accessibility, 2) Pollution and waste matter, 3) Energy, 4) Natural resources, 5) Operation, maintenance and management of environmental friendly campus. And, this study classified five major categories into twenty subcategories on the evaluation of the environmental friendly campus. The twenty subcategories include various fields such as architecture, landscape architecture, environment, urban design, and social sciences etc., profound studies at this line should make more precise assesment guidelines.

As a result of evaluating the level of tritium emitted from the nuclear power plant in the environment and the human body, it was confirmed that tritium was detected in the environmental media and human urine samples to be investigated. It was found that the tritium was clearly detected. After the operation of the Tritium Removal Facility (TRF), which was operated for the purpose of removing tritium from the Wolsong nuclear power plant, the tritium emission showed a decreasing trend, and the tritium level in the environmental media also showed a tendency to decrease accordingly. However, for precise evaluation, it was necessary to select and investigate points by distance, season, and wind direction from the nuclear power plant, but it also showed characteristics that did not reflect this. As the cycle, etc., implemented the previous environmental monitoring program as it is, there was also a limitations in not being able to reflect the changing environment. Therefore, it is necessary to review and supplement the environmental monitoring investigation plan and results so far, and by applying the supplemented investigation plan to secure valid and reliable investigation results, it is judged that it will be an appropriate measure for environmental conservation and human protection in the vicinity of the nuclear power plant.

두 개의 딸기 온실 (농약살포포장, 천적방사포장)에서 점박이응애(Tetranychus urticae Koch)의 고정 정확도 수준에서 표본조사법 (Fixed-precision sampling plan)을 개발하였다. 표본추출은 조사구역당 3개엽으로 이루어진 복엽 1줄기를 기준으로 하여 3줄기를 채취하였다. 각 복엽은 Relative net precision (RNP) 값을 비교하기 위해 3개의 서로 다른 단위(1엽, 2엽, 3엽)로 나뉘어졌다. RNP 값 결과 1엽 단위가 다른 단위들보다 정확도와 효율적인 면에서 우수했다. 공간분포 분석은 Taylor's power law (TPL)를 이용하였으며, 각 딸기 온실별로 계산된 TPL 계수의 동질성검정에는 공분산분석(ANCOVA)을 이용하였으며, 분석결과 차이를 보이지 않았다. 표본추출 정시선을 구하기 위한 TPL 계수는 농약살포포장과 천적방사포장의 딸기 1엽 단위에서 점박이응애 밀도 자료를 합한 뒤 재계산하여 사용하였다. 그리고 점박이응애 발생밀도수준을 3마리와 10마리로 설정하여 방제의사를 결정하였다. 분석에 사용하지 않은 독립된 자료를 이용하여 개발된 표본추출법의 유효성을 Resampling Validation for sampling plan (RVSP)으로 확인한 결과 적합한 정확도를 보였다.
