In this study, a learning environment based on STEAM theory was proposed to support and improve learners' activities and achievements for convergent design education. The learning environment design influence STEAM education with intentional design and schedule coordination, schools can create informal environments that are crucial to STEAM education. The physical surroundings of the learning space should be applied to teaching methods and learning activity, especially for STEAM-based education, physical space conditions should support the learner's design thinking and process. Furthermore, STEAM-based education environment should support a vast array of experiences that allow students to learn the context around ideas and skills. For spaces for learning environment based on STEAM, common design principles should be considered such as technology integration, safety and security, transparency, multipurpose space, and outdoor learning. Therefore, the learning environment based on STEAM needs flexible and mobile, connected, integrated, organized, flipped, and team-focused surroundings to support the learners understand, participate, cooperate, and accomplish the design process.

Oceanic architecture means architectural space created by directly or indirectly using the features of the ocean in the design. A range of marine structure for residential, leisure, cultural, and industrial uses has been and will be created by adopting these features in spatial composition, program, function, and form. This is a clearly distinct category of architecture which can produce unique and creative environments for man's living. Here this kind of architecture is called oceanic architecture. Nowadays the demand for ocean space is increasing and in the near future the law of oceanic architecture will be established by the government. Even with the present trend in design practice, few academic researches on the new architecture have been executed from an architectural design viewpoint. Accordingly, this study aims to examine the design aspects of oceanic architecture. In this paper firstly the design characteristics and contents of oceanic architecture are dealt. And then the concept architecture is defined on the basis of design characteristics.

전통적인 모델 기반 제어 방법은 로봇의 센서계로부터 유추한 현 상황과 로봇이 가지고 있는 주변 환경에 대한 모델을 비교하고 이를 토대로 정교한 경로 계획에 따라 로봇을 구동하는 방식이다. 이러한 방식은 로봇의 주변 환경이 바뀌거나 동적으로 변화하는 경우에는 적용하기 어렵기 때문에 미리 알려져 있고 고정되어 있는 환경이 아니면 로봇이 성능을 발휘하기가 어렵다. 이에 반하여 행위기반 제어는 로봇이 처해있는 주변 환경에 대한 모델이나 경로 계획에 의존하지 않고 로봇의 특정한 센서 출력에 대하여 특정한 행위를 즉각적으로 수행하도록 구성되어 있어서 비구조적인 환경이나 동적으로 변화하는 환경에서 로봇에 적용하기가 좋다. 본 논문에서는 로봇이 처한 상황에 따라서 행위를 달리하는 상황의존형 행위기반 제어 구조를 제안하고 이를 1:1 2족 축구 로봇에 적용하여 그 효용성을 보인다.
