교통정보의 지능화처리에 따라 교통 체계에서의 변화가 전개되고 있다. 특히 전세계적으로 지능화된 첨단 교통 시스템으로 ITS(Intelligent Transportation System)가 등장하여 표준화된 첨단교통 정보의 체계가 진척되고 있다. 본고에서는 ITS 분야 중에서 첨단 여행자 정보 분야인 ATIS(Advanced Traveller Information Service)에 대하여 주행 및 여행자 정보 서비스의 기능 규격을 정리하고 이의 실현 방안으로 검토되고 있는 다양한 무선 데이터 통신망의 적용을 위한 기술을 검토하고자 한다.

As Information society evolves, there is a growing need that substitutes agents for users to do the given Jobs in distributed computing environments. Agents can retrieve and browse the diverse information via Internet, as the users request, and can deal with the complicated routine jobs on behalf of users with timeliness and efficiency. Especially, mobile agent can support the paradigm for distributed application programs in Internet environments. This is suitable to jump-to-jump model without any hesitations because agent moves. Agents can be applied to various applications, but we restrict it to market information retrieval in this paper. On recognizing a query about merchandise information by an user, agent by itself retrieves the corresponding information by navigating the Internet and informs the result to the user. In this paper, we review the mobile agent configuration to do this kind of work, propose the system architecture based on this review. By using this system, users can be free from complicated routine jobs and pursue his/her wishes to promote ones welfare.

대규모적이며 복잡한 공공시설사업의 이행은 재정, 계획, 설계 기타 거대한 상호 연계 Pro-ject의 건설을 통합하기 위한 정선된 절차와 규정이 필요하다고 하겠다. 요즈음 우리 나라의 건설산업기본법에 "건설사업관리(CM)"라는 새로운 건설계약 업종이 대두되면서 실질적인 건설산업현장에서 관리기법의 정의와 다양성을 살펴 볼 필요성이 요구되는 차제에 세계 제7차 "Civil and Building공학의 컴퓨터화"란 주제로 1997년 8월 19~22일 Sheraton Walker Hill 호텔에서 열렀다. 이 대회에서 상기 인천국제공항 건설에 참여한 Parsons Overseas Company의 PE인 Steven B Cornell이 발표한 인천국제공항건설의 Program Management 운영을 간추려 소개한다. 이 Program Management 설명에서 Pro-gram Management(PmMt), Project Mana gement(PM), Construction Management(CM) 등의 정의과 차별성의 파악 및 p. M. 0(Program Management Oversight)의 기능과 역할을 파악할 수 있을 것이라고 판단된다. 파악할 수 있을 것이라고 판단된다.

This subject,'S" apartment structural frame has not been achieved without considerable effort by all quality controller involved. Therefore, it is appropriate at this time to report by all the fact of concrete quality control in our site. These are emphasized that the average strength of placed concrete must always exceed the specified value of design strength used in the structural design phase. In general, quality of ready mixed concrete largely depends not only upon the manner of production and proper observance of recognized methods of placement, finishing, curing, transportation etc. ,but also many kinds of influential factors even more handling of the test procedure, As this practical report, approaching to judgement by analysis of sampled specimens in site weather placed concrete have satisfied quality compare the specified strength with the target strength which is applied to standard deviation related with influential factors as above mentioned. This case study is consist of 1) A foreword, 2) Site brief, 3) A precondition for analysis, 4) A formulas derivation and quality analysis, 5) Economic gains by the coefRcient of increase and 6) A conclusion.sion.

Development of diamond wheel with fine grains and multi-pore structures were newely attempted to be studied in this paper. Wheels, that are employed for the smooth and mirrow finishing of die materials such as tungsten carbide alloy using tool and die materials, must have both performances to remove tool marks efficiently and to contact elastically with curved surfaces. Diamond abrasive grains were bonded firmly by a melamine to prevent the decrease of machining efficiency due to grain sinking within the bond materials. Also, highly foamed structures were developed to increase the flexibility of the wheel, and to induce active self-sharpening by increasing contact pressure between the wheel and work sufaces. In this paper, melamine-bonded diamond wheels are trial manufactured, then the forming method of wheels are explained.

In this paper, we explain Production Liability(PL) law and research method of protection and defence of PL law. In introduction, we give some examples of PL law In main issue, we explain more detail PL law. We survey several country PL law, specially U.S.A., EU, Japan whose are deeply related with us as important export country We discuss our country PL status, our country don't legislate PL law until now We have consumer protection law(소비자보호법) which is weaker than PL law but stronger than civil law(민법), We believe that PL law will be legislated within not long time. At last we discuss protection and defence of PL law inside of company and outside of company as PL insurance.
