Man-machine system is an integrated total system which is linked by functions of man and machine, and the value of the system is determined by its compatability. And it is able to evaluate the system value on the aspects of utility, availability, and cost benefit. The authors previously represented the methodology of system utility using transfer functions, and this paper successively discusses the reliability of man-machine system. The reliability estimation and evaluation methodologies are briefly mentioned, and some examples are shown in this paper.

In designing a man-machine system(machines, work surfaces, work places, etc.), human's internal and external characteristics should be considered. But the resulting system may not be perfect, and many idiosyncratic and situational errors occur while operating. The entropy model with the limited data is known as a useful method to verify the internal system status. This paper shows a quantitative method to describe the system compatability between man and machine by entropy model and error data.

Sequential Function Chart(SFC) is very easy to grasp the sequential flow of control logic and has the compatability for a maintenance, In process control, when an error is occurred, to execute other routine by force, we control the process by remote control. In this paper, we proposed the method of select sequence control by remote control in process control designed by Sequential Function Chart(SFC).

소프트웨어의 중요성이 높아지면서 소프트웨어 품질평가에 대한 관심이 높아지고 있다. 본 연구에서는 소프트웨어 품질 평가를 위한 국제 표준 문서를 비교 분석하고 테스트 데이터 분석을 통한 평가 방안을 제시한다. 국제표준 ISO/IEC 9126-2의 평가 모델과 ISO/IEC 25023의 평가 모델에 대한 차이점을 비교했다. ISO/IEC 25023의 평가모델인 8가지 품질 특성, 즉 기능성, 신뢰성, 사용성, 유지보수성, 이식성, 효율성, 상호운영성, 보안성적인 측면에서 평가 메트릭을 제시했다. 실제 테스트를 통해 얻어진 331개 자료를 분석해서 테스트 데이터의 발견된 오류 특징을 파악했다. 또한 결함 자료를 분석하고 차이점을 파악했다. 테스트데이터가 남녀에 따라서 시험 일수나 발견하는 품질 특성별 오류의 수에는 차이가 있음을 증명하고 시험일수를 기능성, 사용성, 성별을 가지고 예측했으며, 제품의 종류에 따라서도 오류수에 차이가 있음을 증명했다.

본 연구는 한반도의 지진지체구조 특성에 부합되는 내진설계용 부지응답 스펙트럼 작성을 위한 유사지진 선정에 관한 연구이다. Seismic Moment Tensor를 이용 파형을 Inversion한 결과에 의하면 지진원 특성상, Kern Conty 지진(1952년 7월 21일, 리히터 규모 ML = 7.2)은 한반도 지진지체구조 특성에 부합되는 현실적으로 유사한 외국의 지진들 중의 하나로서, 선정된 Kern Conty 지진으로 부터 발생한 강지진동 자료를 전산처리하여 표준응답 스펙트럼과 일반적 특성을 비교하여 보는 일도 의미있는 일이라고 할 수 있다.

This paper focuses on the history of fisheries finance in Korea, especially the role of fisheries finance after the establishments of korean fisheries cooperative. We can say that our fisheries was influenced greatly by the fisheries finance. It may be preyed by the facts that our fisheries experienced a great growth right after the input of big fisheries finance. The products of fisheries has increased from 1962 to now And the structure of the fisheries has improved. But there were unequal development in the each sectors of fisheries. Though the deep sea fishery and farming has developed faster, coastal fishing that are absorbing nearly 90% of fisheries population has stagnated. Of course it was because of unequal financial assistance by Authority. So to improve fisheries evenly, it is very important to overcome various problems that have encountered including the new circumstances like the WTO. For this, lots of steps should be taken. They can be summarized as follows. 1) It may be inevitable to see a rising costs in the deep sea fishery because of the declaration of EEZ by almost every nation. 2) So coastal fishing should be getting more important. It is necessary to improve the structure of coastal fishing and we should be ready to prepare various alternatives far self-sustained growth in coastal fishing. 3) Especially fisheries finance should play more active role. 4) Self-sustainable growth means a fishery with full compatability. For full compatability it is necessary to give financial supports far making fishing ground and equipping anti-pollution system and labour saving apparatus etc. 5) Also to raise the ratio of self-support in fisheries products it is necessary to give financial support to traditional financial system. 6) Moreover it is necessary to guide utilization of finance supplied. For this the committee that is consists of professional people in that field is strongly asked. This committee should be entitled to decide and coordinate the selection of projects, allocation of finance, method of utilization and evaluation of projects etc.

Overhead cranes are the most widely used and have been identified as one of the main causes of fatal accidents. Although structural, mechanical and electrical safety standards for overhead cranes have been established to some extent, ergonomic standards related to crane controllers are rarely established. As a result, many crane accidents are reported to be caused by operator's error. To investigate the actual use of crane controllers in the industrial field, we surveyed 82 overhead cranes in 15 workplace and interviewed workers operating them. This study has presented the ergonomic problems related to the crane controllers in the field. As a result of investigation, it was found that the direction control signs, the sign language, and the button layout on the pendant switches and remote controllers are not standardized, which can cause a human error. To reduce human errors in overhead crane operation, ergonomic standards for controllers should be reflected on the government legislation or standards.

In this paper, systematization design method by analogical Interpretation which is profitable in the compatability and standardization of developed products and is useful of reducing construction time and price was introduced. Systematization design based on analogical interpretation is a method which systematizes each characteristic with mathematical description in order to make variable design parameters correspond with the terms desired. In this paper, after choosing a differential transformer as the sample for design components each characteristic was expressed mathematically by analogical interpretation and miniaturized ones were manufactured by similarity factors. The relationship between input voltages of an actual differential transformer and the model and output voltages occurred by the change of the displacements in operational axis was shown.

In this paper, an EMI reduction effects using an EMC chamber is described and reduction methods is proposed. In the case of general electronic components a working frequency is low. But in this paper the vehicle cluster works 75MHz in the main clock frequency, becoming weak by noise because of being attached in TFT LCD. As the outer case installed in the vehicle is made up of plastic materials, the noise is radiated if not protecting noise in the PCB itself. Therefore, This paper will explain the theoretical basis and propriety with respect to the discussion and need about the guide for PCB design considering EMC, through the reduction of PCB noise.
