Object Oriented Programming Languages including Java require Object-oriented thinking first for programming. However, for Korean students it is not easy since they are fully accustomed to Korean language which does not have the Object-oriented concept. This paper proposes a way of teaching the Object Oriented Languages to Korean students. It explains first how to organize our thoughts in Object-oriented way, and then how to express the thoughts with the languages.

본 논문은 적외선 리모트 컨트롤러로 제어가 가능한 가정용 소형 로봇인 $Robosapien^{TM}$을 홈 네트워크 제어를 위한 홈 서버를 통해 직접 제어할 수 있는 제어 소프트웨어를 개발하였다. 또한 $Robosapien^{TM}$의 연속적인 동작을 쉽게 프로그래밍하고 실행시킬 수 인터프리터 (interpreter)의 세부 구현내용을 기술하였다. 본 구현은 컴퓨터 프로그래밍의 개념 정립이 부족한 일반 사용자나 컴퓨터 프로그밍에 관심이 많은 학생들이 쉽게 프로그래밍 할 수 있는 비주얼 프로그래밍 도구를 개발하였다. 특히 구현 시 필요한 구성 요소 및 기능을 설계하고 사용자의 편의성을 고려한 편리한 GUI(Graphical User Interface)의 구현에 중점을 두었다. 본 비주얼 프로그래밍 도구는 가정의 데스크톱 PC뿐만 아니라, 실외에서 PDA와 같은 소형 이동단말기를 이용하여 원격으로 가정의 홈 서버에 접속하여 $Robosapien^{TM}$의 동작을 실시간으로 제어할 수 있으며 가정의 웹 카메라를 통하여 $Robosapien^{TM}$이 정확하게 동작하고 있는지를 원격으로 확인할 수 있다.

In this paper, virtual reality programming modules were developed for software education advanced courses in elementary and middle schools. And the effectiveness of the developed module was also analyzed. As the result, virtual reality programming module developed in this study was proven to be suitable for software education advanced courses required after basic coding in elementary and middle school. In particular, it is expected that it will be very helpful for the information gifted education program which is carried out in 2,920 gifted education institutions nationwide. Also, it is expected that it will be suitable for STEM education.

Scratch is Educational Programming Language, and it has been widely used in Elementary school SW Education. Many studies show that Scratch education is helpful for students' computational thinking and problem solving. However, the lower grade students use scratch less than the higher grade students, and the higher grade students have difficulty in understanding basic programming principles such as sequence, repetition, and condition. Therefore, in this study, we developed Scratch electronic blocks and programming education curriculum. We had classes for 2nd grade and 6th grade students, and it was confirmed that the score of 2nd grade students' interest about programming increased from 3.28 to 3.58 and 6th grade students' interest increased from 3.41 to 4.09. As a result of the programming basic principles understanding assessment, 84% of the 2nd grade students solved more than 7 of the 9 questions and 62% of the 6th grade students solved more than 7 of the 9 questions.

Comparing with sequential programming, parallel programming has additional complexity due to the consideration of parallelism, communication and synchronization of processes. A synergism between users and compliers should be established, each assisting the other to produce high quality parallel programs. On the above underlying philosophy, we developed a parallel Object-Oriented specification language, POOSL, as preliminary works. However, it is still likely to hard for users to write parallel program because users have to consider grammar of POOSL and to write text-based parallel program. It would be more desirable to provide users wit visual environment for effective parallel programming. Therefore, we propose a visual programming environment. VEPO(Visual environment for Parallel Object-Oriented Programming), based on POOSL in order that users can develop parallel programs more easily and conveniently. It aims at supporting a programming environment in which users can represent their programs more naturally and visually I parallel manner with object-oriented concept and essential steps during parallel program development such as program specification, compilation, execution and animation of execution are integrated. VEPO has useful features for parallel processing. Especially, complicated parallel codes for synchronization and communication of processes are automatically generated in the translation phase, so users can be relieved of writing error-prone parallel codes. The system is targeted to the transputer-based parallel system, MC-3. The graphic user interface of VEPO was implemented using Visual C++. Visual programs descirbed on VEPO are translated into Inmos C and executed on MC-3.

The goal of this study is to assess the effects of Scratch programming classes on preservice teachers by using computational thinking and cognitive evaluations based on Bloom's taxonomy. To pursue this research goal we measured preservice teachers' programming skills using cognitive evaluation items based on Bloom's taxonomy after preservice teachers took one-semester Scratch programming course. In addition, a survey focused on computational thinking (CT) concepts, CT practices, and CT perspectives was conducted. We also conducted artifact-based interviews to unpack preservice teachers' experiences of working on team projects and analyzed their experiences qualitatively. The results of this study are meaningful because we assessed preservice teachers' experiences comprehensively with both quantitative and qualitative methods. In addition, this study provides us with implications for evaluation perspectives in designing programming courses for preservice teachers by adopting Bloom's taxonomy scheme.

Educational Programming Language (EPL) should be learner-friendly and easy to use. Dolittle, an object-oriented educational programming language (EPL), offers programming environment which can be programmed in Korean(Hangul). However, since some Dolittle commands are not appropriate to elementary and middle school students, it shows limitations for learners to express programming process. In this paper, we developed a set of 1:n multi-reserved words which are able to program with Korean linguistic characteristics as well as considering learners' differences, preferences, and applicable areas. The conclusion in the paper showed that programming with this 1:n multi-reserved words helped learners concentrate on problem solving regardless of the reserved words.

소프트웨어 프로세스 모형은 실세계 소프트웨어 프로세스의 개념적인 표현이다. 소프트웨어 프로세스 모형들은 프로세스 프로그래밍 언어를 통해 추상화됨으로써 모형화 될 수 있으며, 프로세스 모형들을 자동으로 수행(enactment)하고, 이미 수행된 프로세스 모형들을 체계적으로 관리하는 수행지원시스템을 통해서 소프트웨어 생산물의 질적인 향상을 기대할 수 있다. 본 논문에서는 소프트웨어 프로세스의 수행 중에 발생할 수 있는 프로세스의 feedback을 지원하는 SimFlex 프로세스 프로그래밍 언어의 확장된 언어구조와 프로세스 수행지원 시스템인 SEED 엔진에서의 효과적인 feedback 지원 방법에 대하여 설명한다.

It can be characterized that contemporary architects intend to establish architectonics which can make it possible to reinterpret the attribute of movement in space and its programming differed from the traditional perception in moving in and out any space through disjoining and reorganizing human behavior and event. This intends reflect new paradigm for subjugating the compelled fuctioning of modern Architecture. This Study review those intends focused on programming as a pre-disign schema. In those intends, it connotes the effort of establishing more systemic and logical approach through deconstruction and disprogramming the existing from, space, elements and human on the basis of his own schematic conception as substitution of function in modern architecture.
