GMDSS(Global Maritime Distress and Safety system) is a new communication system for the distress and safety at sea which is utilizing the recent advancements in satellite communication and positioning system, digital communication system, computer and microelectronic technology, etc., and will completely substitute the current communication system by 1999. Although the improvements of education for producing qualified Radio Operators as well as the establi-shments of policy for accepting the system are required, the educational institutions and relating administ-rations have not yet prepared the rational and concrete schemes on the educational methods and accepting procedures for the system. In this study, as the result of analyzing the GMDSS, courses of training and relating data, the authors suggested principles for improving the course and contents of education and rational schemes for balan-cing the demand and supply of Radio Operators. The authors expect not only the consequences of this study can be utilized as reference materials for the instruction to ratio communication in the organs of education but also that the following effects can be obtained by the study. 1. Security of distress and safety communication system at sea by the establishment of relating regula-tions. 2. Rationalization of the management of radio communication at sea and improvement of the communi-cation system on the vessel. 3. Upgrading the quality of Radio Operators and presenting schemes for current qualified persons. 4. Activation of industry producing radio instruments. 5. Balance of the demand and supply of Radio Operators and development of shipping industry.

An Integrated Bridge System (IBS) is not an officially defined term, but a concept of which integrates on a consol at bridge the primary functions of stand-alone navigational aids and communication instruments or of stand-alone units which are integrated i.e. ARPA ECDIS It aims to enable officers on navigational watch to perform their duty without impairing proper lookout. IBS has been taking shape through a rapid development of navigation and communication systems in relation with bridge configuration bridge work station and one man bridge operation system. IBS related matters have been considered for years and is on the agenda of the International Maritime Organization(IMO) for its technical details and safety aspect of possible one-man watchkeeping at night. However IMO has made it clear that human element should be the key factor in considering IBS and single watchkeeping issue. In the development of IBS ergonomic element and human psychological aspect have been more emphasized than technical requirements. This paper refers to documents presented to the IMO and its progress made in various IMO technical meetings on the development of IBS which is perceived as an effective aid to proper bridge lookout and those standards adopted by classification societies on the composition of workstation at bridge in order to identify the international trend on regulating required equipment function of workstation of IBS the regulatory review process and technical recommendations related thereto.

경기도 동두천시소재 C 특급도계장의 위생상태를 세균학적으로 조사하였으며 작업과정중에 사용되는 물의 세균오염도와 포장된 도계품의 보관기간과의 관계를 조사하였다. 1. 생체취급실과 가까운 작업실일수록 공기중에 세균수가 많았고 사람의 출입이 잦은 제품출하실과 가까운 포장실의 세균오염도가 높았다. 2. 작업개시이전의 장비와 기구에서도 많은 세균이 검출되었으며 양호한 시설일지라도 계속적인 위생관리가 이루어지지 않을 경우 장비와 기구를 통한 오염가능성이 높음을 알 수 있었다. 3. 탕적수의 세균수는 작업 1시간후 부터는 $m\ell$당 표준평판배양 일반세균수가 2$\times$$10^{7}$ , 대장균군최확수 4$\times$$10^{5}$ 정도로 증가되어 작업완료시까지 지속되었다. 4. 도체냉각이 끝나는 부분에서의 냉각수의 $m\ell$당 표준평판배양 일반세균수는 수당 냉각수 용량이 2$\ell$인 경우에는 3.3$\times$$10^4$이며 5$\ell$인 경우에는 3$\times$$10^3$이었다. 또한 냉각수의 유효염소농도가 50ppm일때는 $m\ell$당 표준평판배양 일반세균수가 1/1,000-1/10,000 정도로 감소하였다. 5. 냉각된 도계품의 복강내에 고인 물의 $m\ell$당 표준평판배양 일반세균수는 평균 3.9$\times$$10^4$이었고 포장후 4$^{\circ}C$에서 10일간 저장후 포장용기에 고인물의 $m\ell$당 표준평판배양 일반세균수는 평균 4.7$\times$$10^{7}$ 이었다. 변패취는 $m\ell$당 일반세균수가 $10^{6}$이상일 때부터 나기 시작하였고, 냉각후 도체 복강내 고인 물의 일반세균수가 $m\ell$당 $10^4$이상 검출되는 도계품은 4$^{\circ}C$에서 5일이상 저장할 수 없었다.다.
