Most programming languages are designed based on English. It becomes another barrier in learning programming languages in non-English speaking country. If a programming language is presented using a native language, the education cost of programming will be much cheaper and the programming itself can be much more fun. However, designing the programming languages based on native languages has not been much focused or published up to now. It is partly because the evolution of popular programming languages is so fast, and partly because the efficiency of programs is much stressed than the source code. But, the designing of programming languages based on native language is not a small issue, especially if we reflect on the education of programming. In fact, there have been significant efforts reported in the Korean programming languages so far, but it has not practically been used in the education. This paper introduces yet another Korean programming language, namely Sprout, which is concise and can be easily learned by beginners. To demonstrate the conciseness of Sprout, we have performed two experiments on Sprout. Firstly, we compared the sizes of the programs in Sprout with those in former Korean programming languages. Secondly, we compared the size of Sprout, the language itself, with those of popular programming languages such as C and Python. According to the experiments, Sprout programs are more concise to 10% on average than those in former Korean languages. Furthermore, Sprout itself is more compact to 24% on average than other popular programming languages.

텍스트 기반 언어 스몰베이직은 적은 수의 언어 특징을 가지고 있어 배우기 쉽고 이후에 C/C++/Java로 빠르게 전환할 수 있기 때문에 청소년 코딩 교육용 언어로 적합하다. 코딩 교육에 흥미를 높이기 위해 다양한 라이브러리가 필요한데 마이크로소프트에서 개발한 스몰베이직 환경에서는 로봇 프로그래밍을 위한 라이브러리를 지원하지 않는다. 이 논문에서 오픈소스 소프트웨어 스몰베이직 환경하에 동작하는 햄스터 로봇 라이브러리를 설계 및 구현하였다. 교육용 언어 스크래치와 파이썬에서 유사한 로봇 프로그래밍 라이브러리를 지원하지만 스크래치는 그림 기반 언어이기 때문에 이후 C/C++/Java로 전환하기 어렵고, 파이썬은 객체와 클래스 개념을 포함하고 잇어서 초보자가 배우기 어렵다. 이 논문에서 개발한 라이브러리를 활용하여 데모 프로그램을 작성함으로써 쉽게 스몰베이직 기반 로봇 프로그래밍을 할 수 있을을 확인하였다.

In this study, the study conducted an analysis of the generic type of personality classes in the programming language class of the industrial high school, and conducted a thorough identification of the central type. Learners studied C language in the preceding academic year. Typology and classes of Java programming followed by classes. Prior to the start of the fourth week of the school semester, it conducted a preliminary examination of the contents of the contents of the C language similar to those of C language and language, and conducted a preliminary examination before the vacation ceremony. Through this study, we learned the difficulties and benefits of learning various programming languages.

This paper proposes several methods for effective teaching of programing language(especially C). The programing languages are very important and basic subjects in the Department of Computer Engineering and Science. Many students have some difficulty in learning the programming languages. So, we will suggest several effective methods for effective teaching of programming languages. First, in order to understand the programming language effectively, we need to teach some basic computer architecture and operation principles of computer program to students. Second, it is better to teach many example-based programing skills instead of conventional grammar teaching. Third, if we teach the memory status(memory allocation/release) during the program operation, it will be much better to understand the pointer variables and memory problems. Fourth, let's improve the programming skills through effective homework assignments and experiments. Fifth, let students be guided so that they do programing by themselves. Finally, we can maximize the programming skill through the final termproject.

Programmers use multiple languages to reuse legacy code best suited to their problems. However, it is quite challenging to develop error-free multilingual programs because new types of bugs occur since misunderstanding about language interfaces such as Java Native Interface (JNI) and Python/C. There is a considerable amount of research to overcome multilingual program bugs and errors but these researches have less consideration about substantiality of programming languages, language interfaces, and bugs to evaluate their analyses and tools. In this paper, we have identified and establish substantiality of multilingual programming research with empirical study about diversity and interoperability of programming languages in Ubuntu software ecosystem based on real-world statistical data.

The purpose of this study is to find the programming capability for the students majoring in H/W. For implementing this purpose, first, the academic achievements on the C language and C++ language are measured for the graduates-to-be majoring in H/W and S/W. Second, the H/W and S/W curriculum are compared and analyzed to derive the relevant factors to give influence on the academic achievement of the programming. Third, to find the influence of mathematic competence on the academic achievement of the programming, the relevance is analyzed in terms of the regression analyses between mathematics curriculum and programing curriculum. This paper presents the effective teaching method for the improvement of the programming academic achievement in the H/W curriculum.

We now live in a society that is highly information-oriented, and as a result programming education has become more important and is emphasized day by day. Currently, there is strong support for carrying out programming education in early childhood, and various Web-based services have launched to provide programming education. Currently, Web-based programming education services have not yet launched in Korea. In particular, Web-based education services for C language programming, which is used in various areas in industry, are lacking due to limitations in the development environments. In this paper, we design and implement a Web-based programming learning system, 'ICANC', to provide the necessary information to learn and practice the C language.

Since most of information is computerized nowadays, it is extremely important to promote the security of the computerized information. However, the software itself can threaten the safety of information through many abusive methods enabled by coding mistakes. Even though the Secure Coding Guide has been proposed to promote the safety of information by fundamentally blocking the hacking methods, it is still hard to apply the techniques on other programming languages because the proposed coding guide is mainly written for C and Java programmers. In this paper, we reclassified the coding rules of the Secure Coding Guide to extend its applicability to programming languages in general. The specific coding guide adopted in this paper is the C Secure Coding Guide, announced by the Ministry of Government Administration and Home Affairs of Korea. According to the classification, we applied the rules of programming in Sprout, which is a newly proposed Korean programming language. The number of vulnerability rules that should be checked was decreased in Sprout by 52% compared to C.

The PLC programming by IEC1131-3 is hard to handle to ordinary users as well as professionals. Also it has not a generality, so that it couldn't be debugging some logic errors easily. In order to be adapted for such environment, In this paper, I have developed the ISPLC(Intelligent Agent System based Software Programmable Logic Controller). In ISPLC system, LD programmed by a user is converted to the C code which can be used in a commercial editor such as Visual C++. The detection of logical errors in C code is more effective than PLC programming itself. ISPLC provides the GUI-based interface in web environment and an easy programming platform to such beginners as well as professionals. The study of code conversion of LD to IL as well as IL to C is firstly tried in the world as well as KOREA. To show the effectiveness of the developed system, I applied it to a practical case, a real time traffic control system. ISPLC is minimized the error debugging and programming time owing to be supported by windows application programs.
