This study aims to conduct fairy tales-utilizing group play program for children with mild intellectual disability to see if their self-efficacy improved. A speech therapist requested children who used S treatment room located at P city to take self-efficacy test. Among them, the subjects of this study are three(3) 11 years olds who received lower scores in the test. The goal of this fairy tales-utilizing group play program is to improve self-confidence, self-regulation efficacy, and preference for task difficulty. We conduct a total of 12 sessions for this program: 60 minutes per session, twice a week. Each session includes relaxation activity(10 min.), structured activity(25 min.), and discussion activity(5 min.). We present the impact of the fairy tales-utilizing group play program on children's self-efficacy by conducting a self-efficacy test before and after the program. We also videotape children's free play situations in every session, make a qualitative analysis of the self-efficacy behavior by session according to the self-efficacy behavioral observation scales and present frequency. Our findings are as follows: First, the fairy tales-utilizing group play program improves the self-efficacy in children with mild intellectual disability. Second, the self-efficacy behavior within a session increases during the fairy tales-utilizing group play program. In conclusion, because this study covers only a few subjects, the study has limitations in its generalization. However, it is important to note that but the fairy tales-utilizing group play program was found to be effective in improving the self-efficacy in children with mild intellectual disability. 본 연구는 경도 지적장애 아동에게 동화를 활용한 집단놀이 프로그램을 실시하여 자기효능감을 향상시키는지를 알아보는데 목적을 두고 실시되었다. 연구대상은 P시에 소재한 S치료실을 이용하는 아동 중 언어치료사가 의뢰하고, 자기효능감 검사에서 낮은 점수를 받은 만11세 아동 3명이다. 연구문제는 첫째, 동화를 활용한 집단놀이 프로그램이 경도 지적장애 아동의 자기효능감에 영향을 미치는가? 둘째, 동화를 활용한 집단놀이 프로그램이 경도 지적장애 아동의 자기효능감 행동 변화에 영향을 미치는가? 이다. 동화를 활용한 집단놀이 프로그램의 목표는 자신감, 자기조절효능감, 과제난이도선호를 향상시키는 것이다. 프로그램은 주 2회, 1회기 60분, 총 12회기로 실시하였고 매 회기는 이완활동(10분), 구조화된 활동(25분), 토론활동(5분)으로 진행하였다. 동화를 활용한 집단놀이 프로그램이 아동의 자기효능감에 미치는 효과를 프로그램 실시 전, 실시 후에 자기효능감 검사를 실시하여 제시하였고, 매 회기 자유놀이 상황을 녹화하여 자기효능감 행동을 자기효능감 행동 관찰 척도에 따라 회기 별로 질적 분석하여 빈도를 제시하였다. 본 연구의 결과는 다음과 같다. 첫째, 동화를 활용한 집단놀이 프로그램은 경도 지적장애 아동의 자기효능감을 향상시킨다. 둘째, 동화를 활용한 집단놀이 프로그램은 경도 지적장애 아동의 자기효능감 행동을 향상시킨다. 따라서 본 연구는 소수사례 실험연구로 일반화하는데 제한점이 있으나, 동화를 활용한 집단놀이 프로그램이 경도 지적장애 아동의 자기효능감을 향상시키는데 효과가 있었음을 알 수 있다.

In this paper, we proposed a system that efficiently provides support maps which includes the grid based terrain analysis information. To do this, we use the FDB which is defined as a GIS database that contains features with attributes attached to the features. The FDB is composed of a number of features and feature classes. In order to create support maps, it is necessary to classify feature classes that are associated with each support map and to search them in a grid map. The proposed system use a ontology model to classify semantically feature classes and the quad-tree data structure to find them in a grid map quickly. Therefore, our system is expected to be utilized for global path planning of UGV. In this paper, we show the possibility through an experimental implementation.

Terrain Trafficability Analysis for Autonomous Navigation: A GIS-based Approach

박원익,김도종,이호주 제어·로봇·시스템학회 2013 International Journal of Control, Automation, and Vol.11 No.2

This article presents a method of generating grid maps for autonomous navigation using a geographic information system (GIS). Besides developing ordinary map systems, a GIS can be applicable to the terrain trafficability analysis for an unmanned ground vehicle (UGV) by generating maps in which information about its spatial environment is encoded for path planning as part of autonomous navigation. For such maps, the most commonly used is a grid map over which a UGV’s paths can be optimized. As the UGV moves and its situation changes, grid maps need to be generated quickly in an automatic manner for new paths. First of all, a GIS is analyzed to identify meaningful data, layers and attributes, which are then related to the UGV’s navigation. For each grid in the grid map, every mean-ingful layer included is processed so that the set of values of attributes of the layer can be converted into the traverse cost. If multiple layers are included in a single grid, those traverse costs are fused and the result data is then replaced in the grid. Grid map generation is finished after all grids are filled with such costs. From test results using an experimental program, it is validated that the proposed method can be a viable tool for the timely generation of grid maps using a geographic information system for the UGV’s autonomous navigation.

축력과 양단 비대칭모멘트를 받는 단일곡률 스테인리스 원형강관 보-기둥의 좌굴내력에 관한 실험적 연구

This study presents a series of experimental investigations on buckling strength of eccentrically compressed cold-formed stainless steel CHS(circular hollow section) columns. The principal parameters in this study are slenderness ratios(Lk/r = 30, 50, 70) and magnitude of eccentricity e(one way : 0, 25, 50, 75, 100㎜, the other way : 0, 12.5, 25, 37.5, 50㎜) for single-curvature asymmetrical end moment. Objectives of this study are to obtain the maximum loads by performing an experimental work and to compare the experimental behaviors with analytical results. The ultimate buckling strength of CHS members is evaluated by a numerical method for axial force-bending moment(P-M) interaction curves. The behavior of each specimen is displayed in the form of strength-displacement and moment-angle(M-θ) relationship. The numerically obtained ultimate buckling interaction curves of beam-columns show a reasonably good agreement with the available experimental results for slenderness ratio 30. But experimental results for slenderness rations 50, 70 were below M-Pinteraction curve.

The future battlefield operation concept does not focus on advanced and complete weapon systems, but requiresa new battlefield operation concept that can effectively demonstrate offensive power by combining a large numberof low-cost, miniaturized weapons. Recently, research on the autonomous application of major technologies thatmake up the mission control system is actively underway. However, since the mission control system is stilldependent on the operator's operating ability when operating multiple robots, there are limitations to simplyapplying the automation technology of the existing mission control system. Therefore, we understand how changesin operator capabilities affect multi-robot operation and propose an adaptive mission control architecture designmethod that supports multi-robot integrated operation by adjusting the level of autonomy of the mission controlsystem according to changes in operator capability.

본 연구에서는 스테인리스 강관의 구조재로서 적용성 검토를 위해 편심 축하중을 받는 스테인리스 원형강관 보-기둥에 대한 좌굴강 도와 거동을 파악하고자 한다. 주요변수는 축력과 양단 비대칭 모멘트를 받는 이중곡률 보-기둥에 세장비(細長比)와 편심비(e/k)로 한 스테인리 스 원형강관의 최대내력 및 변형능력 등의 역학적 특성을 규명하며, 이론해석을 통한 실험값과 비교함으로서 스테인리스 강관 구조설계을 위한 기초 자료를 구하는데 그 목적이 있다. 실험결과를 해석결과와 비교해본 결과, 세장비 70의 편심비가 0인 시험체만이 낮고, 그 외 모든 시험체는 해석을 통한 M-P 상관곡선을 상회하는 결과를 보이나, 편심비가 작을수록 해석값에 근접하고 있어, 이론해석에서 적용한 세장비를 고려한 좌굴계수나 강도저감계수가 스테인리스 원형강관에 대해서는 별도의 값이 적용될 가능성이 있는 것으로 판단되며, 더 많은 실험에 의해 확증되어야 할 것이다. This study is a series of experimental investigations of the buckling strengths of eccentrically compressed, cold-formed, stainless-steel, circular, hollow-section beam columns. The principal parameters that were used in this study were the slenderness ratios (Lk/r = 30, 50, 70) and the magnitude of eccentricity e(one way: 0, 25, 50, 75, and 100mm: the other way: 0, 12.5, 25, 37.5, and 50mm) on the asymmetrical end-moment of a double curvature. The objectives of the study were to obtain the maximum loads through an experiment and to compare the experimental behaviors with the analysis results. The ultimate buckling strength of the square section members were evaluated using a numerical method, in accordance with the bending moment-axial force(M-P) interaction curves. The behavior of each specimen was displayed in the form of the strength-displacement and moment-angle(M-$\theta$) relationship.
