현대사회는 4차 산업혁명 시대가 도래하면서 초연결, 초지능, 초융합 사회로 변화되고 있다. 최근 교육부는 많은 변화가 요구되고 있는 교육분야, 교육정책 방안으로 SW(소프트웨어)교육에 AI(인공지능) 교육까지 추가되야 한다고 제안하고 2024년까지 첨단 기술을 활용한 지능형 과학실을 구축한다고 밝혔다. 이에 본 논문에서는 정부의 교육정책 방안이 원활하게 진행될 수 있고 융합 교육 분야에서 활용될 수 있는 "미래 지능형 과학실 활용을 위한 화학원소기호 이미지 기계학습 AI·SW교육 프로그램"을 제안하고자 한다.

A Hardware system of hybrid environmental control was developed for using it in the multi-greenhouse. Now, an on/off control system is most utilized in protected cultivation, but a hybrid environmental control system is not yet. This system consists of a hardware to be devided by physical elements and a software for the hardware a personal computer, a hybrid environmental control and a communication Program for modules. The hardware was made of several independent modules with independent CPU. Each module was made to slots. which are very convenient to mount and take off. Also, they are managed easily to repair, add, remove, and change of their function and expansion. The software for a personal computer was a menu driven program written in visual basic within a Windows environment for easy applications by a user. The hybrid environmental control software have operating factors operate continuously with temperature, humidity and others in greenhouse. Communication programs were used both 485 communication method for long distance communication between modules and CRC communication method for making easy to program, and less errors between personal computer and modules.

This paper presents the study on the development of a DNC, system IPIS(Interactive Plant Information System)/DNC, which can manage NC machines and robots as a distributed control method in the machine. processing factory. The IPIS/DNC system is composed of a host computer, satellites and NC machines. A set of software modules are developed on the host computer and the satellites separately. By modularizing each functions of the IPIS/DNC system and using multi-taking method, the functions such as NC program management, NC program distribution, and shop monitoring can be performed on the host computer, and the functions such as NC program transfer to the NC machines, and NC program editing can be performed on the satellites. A Relational database which is linked with job scheduling system is used for IPIS/DNC system.

A system using a personal computer has been developed for Polymerase Chain Reaction, an amplifying process of specific DNA. This system is composed of software and hardware which contains a control system, a heating and cooling system, a multichannel A/D converter, and a personal computor. The software is programmed'in assembly'and basic language. The newly developed PCR system which is controlled by the program of the personnal computor can be applied 1.o the amplification of various DNA. This system was tested by using Mycobacterium tuberculosis DNA and showed the DNA band on the UV transilluminator.

A software package CARDS for general purpose robot design, control, and simulation has been developed and is presented here. CARDS (Computer Aided Robot Design and Simulation) consists of a collection of standardized subroutine modules that carry out typical kineamatic, dynamic, and control computations so that the user only needs to write a main program that further defines a particular robot configuration and the task to be performed. It provides users a complete simulation environment, so that it will be a valuable engineering tool for mechanical designers as well as electric control designers.

The development of automatic production systems has a trend toward Computer Integrated Manufacturing System(CIMS) in recent years. In hardware configuration, CIMS are composed of intelligent CAD/CAM work stations, multifunction CNC machining centers including material handling systems. The DNC systems present the key element of automation hierarchy in a FMS. A DNC system is one which connects a number of numerically-controlled machines to a common memory in a digital computer for part program storage with provision for on-demand distribution of part program data to machines using communication in hierarchical structure of central computer, control computer and cell controller. This paper describes the development of Behind-the-Tape-Reader(BTR) type DNC system using CYBER 180-830 as a central computer and IBM PC-386 cell control computer and NC lathe with FANUC 5T NC controller. In this system, the connection between central computer and cell control computer is done via RS-232C serial interface board, and the connection between cell control computer and FANUC 5T controller is done via parallel interface board. The software consists of two module, central computer communication module for NC program downloading and status uploading, NC machine running module for NC operating.

In the conventional computing environment, users use only a small number of software systems intensively. So it had been enough to check and guarantee the functional correctness and safety of a small number of giant systems in order to protect the user systems and their information inside the systems from outside attacks. However, checking the correctness and safety of giant systems is not enough anymore, since users are using various software systems or web services provided by unskilled developers. To prove or guarantee the safety of software system, a lot of research has been conducted in diverse areas of computer science. We will discuss the on-going approaches for guaranteeing or verifying the safety of software systems in this paper. We also discuss the future research challenge which must be solved with better solutions in the near future.

At present, there is only a few software for power system analysis. Most of programs are run in user computer, which may restrict of running program. In this paper, the software is developed using java and make server take full charge of running the program. So the client only play a role of input and output of the data, which can run the program if client has a web browser. As constructing of database, capability of processing the data and reliability are improved.

The problem of software bottle-neck may be arised from unbalance of demands and supply of software. This is caused from the fact that the capability of programmer could not be improved in software development. Therefor, the new method of software development should aim at improving the productivity of software. This paper presents the expressions to be the standardized software Program modules by means of the software chip. The expressions are consist of name, input, output, and iteration of each software chip. And they simple express a combination and separation in sequence, parallel, iteration, composition, mixing, and variety form. Therefore they can easily software reuse as a result of analyzing the flow of data clearly.
