ANSI C 언어는 UNIX 시스템에서 뿐만 아니라 DOS 환경에서 수행되는 C 컴파일러와 각종 지원 도구가 개발되어 보급됨으로써 오늘날 널리 사용되는 범용 프로그래밍 언어 중 하나이다. EVM(Embedded Virtual Machine)은 ANSI C 언어와 SUN사의 Java 언어 등을 모두 수용할 수 있는 임베디드 시스템을 위한 가상 기계이며, SIL(Standard Intermediate Language)은 EVM에서 실행되는 중간언어로 다양한 프로그래밍 언어를 수용하기 위해서 객체지향 언어와 순차적 언어를 모두 수용하기 위한 연산 코드 집합을 갖고 있다. EVM을 위한 ANSI C 컴파일러는 ANSI C 언어를 받아 들여 EVM의 중간 언어인 SIL 코드를 출력한다. ANSI C 컴파일러에서 어휘 분석과 구문 분석 과정에서 인식되는 명칭에 대해서 그 속성들을 수집하고 이용한다. 이 속성들은 명칭이 명시적으로 혹은 묵시적으로 정의되는 곳에서 심벌 테이블에 수집된다. 본 논문에서는 수집된 정보가 올바르게 되었는지 확인하기 위하여 심벌 테이블에 있는 정보를 다시 ANSI C 언어로 복원시키는 역변역기(detranslator)를 구현하였다.

In this paper, we propose the elementary school teacher's training direction for effective SW education. In an effort to better understand the efficient SW training contents and methods for teachers, 200 of elementary teachers had been selected from different places in South Korea. The results showed that 1)it should be operated by focusing on the training of female teachers, especially, strengthening the contents of SW ethics. 2)It will need to actively operate the teacher training program to foster the necessary computational thinking and programing for elementary school teacher who work in big cities. 3)It need to create a training program for expanding the SW studying groups. 4)In order to improve the effectiveness of training courses in the development of in-service training programs, the SW ethics contents need to be coordinated with the link the computational thinking and programing. These results are expected to provide the efficient methods to design the future SW training programs.

This study presents the unit control of a PC (Personal Computer) program using multiple smartphones based on ad hoc communication. A design of the data packet that multiple smartphones send to a computer, and a framework that manages and controls the unit in a computer after analyzing the data packet, are proposed. As a result, multiple users are able to control their own units using their smartphones while seeing the monitor connected to a computer. In other words, multiple users can share the same game in a computer or control their units embedded in a system using their smartphones. An experimental result shows that a racing game in a PC can be realized by the proposed communication interface, where four iPhones are used to control their units in a computer. Thus, the proposed framework can be effectively used for unit control in a PC using multiple smartphones.

A new slab design using secant stiffness, Direct Inelastic Slab Design, was developed. Since basically the proposed design method uses linear analysis, it is convenient and stable in numerical analysis. At the same time, the proposed design method can accurately estimate the inelastic strength and ductility demands of slab because it can analyzes the inelastic behavior of structure using iterative calculations for secant stiffness. In the present study, the procedure of the proposed design method was established, and a computer program incorporating the proposed method was developed. Design examples using the proposed method were presented, and compared with traditional nonlinear analysis, and experiments. The Direct Inelastic Slab Design, as an integrated analysis/design method, can directly address the design strategy intended by the engineer, such as moment strength and ductility limit. As a result, economical and safe design can be achieved.

The purpose of this study is to develop verbal interaction analysis program for supporting teaching consultation. For this a class language analysis program was developed to manage analysis results systematically in various angles. The program has following characteristics. First, program users can create the frame of analysis tool freely, so he can analysis a class as a desired. Second, qualitative analysis results as well as quantitative analysis results can be acquired. Third, personalized analysis is available, as users can set program environments freely such as analysis unit time, video player environments, and input and output file type. Finally, it can record and manage activity results according to class consulting procedures systematically. It is expected that this program will allow class consulting to be in place in school fields in more professional way.

Purpose: The purpose of this study was to develop a self-directed e-learning program for ICU nurses and to evaluate how the proposed e-learning program affects the level of knowledge, nursing performance and job satisfaction of ICU nurses. Methods: The e-learning program was developed with the Computer Assisted Instruction Design Model using sources of self-efficacy which included the inactive attainment, vicarious experience, and verbal persuasion of ICU nurses. The program was evaluated by experts. Following the revision of the program, it was applied to a total of 59 ICU nurses (experimental group n=29, control group n=30) from three hospitals. Four weeks later, we measured the level of knowledge, nursing performance and job satisfaction. Results: The level of knowledge significantly improved in the experimental group (t=5.691, p<.001). Moreover, the level of nursing performance significantly increased in the areas of circulatory diagnostic test (t=2.143, p=.039), EKG (t=2.911, p=.006), aortic balloon pump (t=2.491, p=.017), and nebulizer therapy (t=2.085, p=.044). Overall, job satisfaction did not significantly increase (t=1.664, p=.105); however, job satisfaction in terms of relationships with coworkers (t=2.371, p=.023) and the needs of nursing performance (t=2.940, p=.006) were significantly increased. Conclusion: The results showed that the proposed e-learning program using sources of self-efficacy from ICU nurses was an effective learning method to increase the level of knowledge and nursing performance. The propose de-learning program would be a useful teaching tool for ICU nurses improving the quality of ICU patient care.
