The research is aimed at investigating the development and application of high school biology classes utilizing discourse-typed inquiry learning program fitted with POE, and the corresponding effect on student's academic achievement and attitude toward science. 4 classes of 11th graders in a general high school located in Busan were selected as subjects. Biology I, 'Circulation' unit was lectured for 4 weeks (6 classes), and the experimental group underwent classes utilizing discourse-typed inquiry learning program fitted with POE. The control group was taught identical major learning contents, but based on the learning objectives and research activities provided by Biology I textbook. As a result of application, first, the discourse-typed inquiry learning program fitted with POE exhibited positive consequences of linking previously acquired knowledge and the new learning attained through experiments, as well as not only improving the students' problem solving capacity through diverging questions from the teachers to drive the students' higher-level contemplation, but also enhancing student academic achievement by assisting their logical thinking. Second, POE-fitted discourse-typed inquiry learning program rendered presupposing session of the experiment that resulted in drawing learners' attention in advance, and incited active participation in the learning process through solving the contradiction between what was actually observed and what was expected, which eventually proved to lay out positive impact on students' attitude toward science.

본 연구는 1990년대 시행되었던 학교시설 현대화 사업 이전 시기인 1970년대 초와 1980년대 초 학교건축에서의 탈표준화를 모색했던 연구들에 주목하여 이들을 고찰하였다. 이들 연구는 후속 사업으로 연결되지는 못했지만 편복도형의 극복이나 시설프로그램의 변화, 학교 건축계획에서의 도시적 차원의 접근, 학교공간 내에 다양한 공간 적용 등을 제안하고 있어 국내 학교건축이 표준화교사로부터 벗어나는데 선례적인 연구로서의 의미를 갖는다.

Parkinson's disease is a degenerative neurological disease that affects even basic daily life movements due to impairment of body function caused by a lack of dopamine, which is charge of the body movement. Presently, it is hard to cure Parkinson's disease entirely with medical technology, so movement therapy as a solution to delay and prevent disease is getting more attention. Therefore, this study aims at desiging and disseminating a body movement program that concentrates on individual self-care and balacing the state of body and mind by applying the Feldenkrais Method® to patients with Parkinson's disease. The Feldenkrais Method® is a mind-body perceptual learning method using body movements. It is a methodology that re-educates the nervous system by connecting the brain and behavior as a function of neuroplasticity. In this study, the body movement program developed and verified by the researcher was modified and supplemented with a focus on the self-awareness of the Feldenkrais Method®. A 24-session physical exercise program was composed of 5 stages to improve the self-management ability of patients with Parkinson's disease. The stages include self-awareness, self-observation, self-organization, self-control, and self-care. The overall changes recognize one's condition and improve one's ability to detect modifications in the internal sense and external environment. In conclusion, the body movement program improves the body movement program improves mental and physical functions and self-care for Parkinson's disease patients through the Feldenkrais method. The availability of the program's on-site applicability remains a follow-up task. Furthermore, it is necessary to establish a systematic structure to spread it more widely through convergent cooperation with the scientific field applied with metaverse as a reference for the wellness of the elderly.

본 연구는 도시토지이용의 적합성분석을 실시하는 데 있어 GSIS와 인공신경망의 유기적인 결합을 시도해 보았다. 인공신경망은 학습이라는 과정을 통해 신경망 노드(node)간의 연결강도를 합리적으로 결정할 수 있는 이점이 있다. 이러한 점에서 공간분석에서 요구되는 인자간의 경중률과 신경망의 연결강도는 대체가 가능하리라 판단된다. 본 연구를 수행하기 위해 두 종류의 신경망을 구성하였다. 1차 신경망은 토지이용별 적합성 분석에 적용했으며, 2차 신경망은 최적의 토지이용패턴을 분석하기 위해 구성하였다. 이들 신경망은 C++로 작성된 프로그램에 의해 구현된 최급강하법에 의한 역전파 알고리즘에 의해 학습을 실시하였으며, 활성화 함수는 시그모이드 함수를 사용하였다. 분석결과는 현행 용도지역제에서 주거, 상업, 공업, 녹지에 대한 토지이용 적합도면과 4가지 유형의 토지이용에 대한 대상지역의 최적토지이용패턴을 제시한 도면으로서 Arc/Info의 Grid 형식으로 작성하였다. 또한 토지이용별 적합도면상에 나타난 적합지역과 최적토지이용패턴은 위치적인 면과 공간 구성에 있어 실제의 도시토지이용계획의 이론적인 개념에 매우 합치되는 분포형태를 보였다.

In this study, we developed the program for 'Discretionary Activity' focusing on the multiple activities with everyday-life materials to enhance scientific creativity (MAEM-SC), which was specifically for students in the 6-7th grade according to the 7th curriculum in Korea. As important factors for scientific creativity, we selected the ability to find out the context relevant to scientific problems, the ability to connect the problem context to scientific knowledge, the ability to invent the ways to solve the problem scientifically, and ability to concentrate on the scientific problem solving activity. The topics of the program were drawn from common and familiar things in our everyday contexts, such as human body, everyday tools, food, play and toys, and everyday episodes. The multiple activities here mean the activities which are systematically constructed with the various types of activities with a specific intention. The multiple activities were designed in three types, that is, series type, parallel type, and combination type. Each of them consists of the several activities as follows: estimating and measuring, carrying out an experiment using body, inventing implement (tools), thinking statistically, writing creatively with scientific themes, and connecting one concept to another concept etc. Through a trial of the program, we found that this program has some positive influence on the enhancement both of the ability to find out the context relevant to scientific problems and the ability to connect it to the students' existing scientific knowledge.

Aiming at time-dependent performance prediction of Liquid Rocket Engine(LRE) system, Modular Program for Conceptual Design of LRE is reviewed, and a modeling and dynamic analysis of rocket engine system with reference to Rocket Engine Dynamic Simulator(REDS) is outlined. Component modeling is based on classical thermodynamic and inviscid theories, and were formulated mathematically in terms of essential parameters. Essential design parameters are addressed. The rocket engine is modeled as a system of pipes with various hydraulic elements, and then the operate characteristic of that elements are simulated by solving conservation equation sequentially.

ATM/B-ISDN 신호 프로토콜과 같은 통신 프로토콜의 상호운용성을 시험하기 위한 시험경우를 생성하는 알고리즘이 제안되었다 1]. 현재까지 상호운용성 시험경우 도출을 자동화하거나 이에 대한 커버리지를 분석한 경우는 없다. 본 논문은 1]에서 제안한 알고리즘을 프로그램으로 구현하여 TCP 연결설정 프로토콜에 적용하고 결과를 분석한다. 이 과정에서 (1) TCP 연결설정 프로토콜의 3방향 핸드 쉐이킹 부분을 다루지 못했던 기존의 알고리즘을 개선하고, (2) 개선된 알고리즘을 프로그램으로 구현하여 TCP 연결설정 프로토콜의 상호운용성 시험경우를 도출하고, (3) 생성된 상호운용성 시험경우를 트랜지션 커버리지 관점에서 분석하고, (4) 향상된 트랜지션 커버리지를 얻기 위하여 알고리즘 확장 방안을 제시한다.Abstract A test derivation method suitable for testing interoperability for the class of communication protocols like the ATM/B-ISDN signaling protocol was proposed 1]. Up to now, there is no work on automating derivation of the interoperability test suite and analyzing its coverage. In this paper, we implement the algorithm proposed by 1], apply it to the Transmission Control Protocol (TCP), and analyze its results. In this process, we (1) improve the algorithm that is not applicable to the TCPs three-way handshaking, (2) implement the improved algorithm as a program and derive an interoperability test suite automatically from a given pair of TCP FSMs, (3) analyze generated interoperability test suite in view of transition coverage, and (4) present a method in order to extend the algorithm for better transition coverage.
