  • 선박의 충돌회피 방법을 제시하는 관점에 있어, 두 선박의 조우각도에 따른 속력이 충분히 고려되어야 할 것이다. 하지만 선박의 충돌회피를 위해 새롭게 연구된 근접상황 선박충돌회피지원 모델의 Safe-Guard Ring 설정은 본선과 상대선박의 속력비가 약 1.7 이하로 제한되어 있으므로 제한된 범위 이외의 경우에서 충돌 위험이 존재 할 수 있다. 따라서 본 연구에서는 두 선박이 조우하는 각도 및 속력을 고려한 Safe-Guard Ring 설정을 연구함으로써 안전한 충돌회피 조종을 위한 선박충돌회피모델을 제시하고자 한다.

  • 국제해사기구의 선박재활용 국제협약에서 쟁점이 되고 있는 부분을 연구하고, 해양경찰의 현 실태를 분석하여, 선박재활용 분야에서 해양경찰이 새로이 담당하여야할 업무 부분을 중심으로 국내법상 수용방안을 마련하는 것이 필요하다. 해양경찰은 해양환경의 보호와 직접적이면서도 밀접한 기능을 담당하고 있으므로, 해양경찰이 담당할 업무의 법적근거를 마련함으로써, 새로운 업무영역을 확보할 수 있을 뿐만 아니라 해양환경 분야에서도 중요한 역할담당자로서 자리매김 할 수 있을 것이다.

  • 선박의 충돌회피조선에 있어서 조종성능은 중요한 요소이다. 일반적으로 사용되는 조종성능은 심수역을 대상으로 작성되며, 천수역을 항주하는 선박의 조종성은 일반적으로 선회성은 저하되고 침로안정성 또는 추종성은 향상된다. 이러한 선회성의 변화는 충돌회피에 있어 위험을 초래할 수 있다. 본 연구에서는 천수역의 조종성능을 반영함과 동시에 충돌위험정도를 쉽게 파악할 수 있도록 하기 위한 가변안전경계영역의 새로운 적용기법을 제시하였다. 수학적 수치시뮬레이션 검증을 통하여 새롭게 제안된 기법의 유용성을 확인하였다. 따라서 선박충돌위험에 대한 충분한 충돌회피 조선을 지원할 수 있을 것으로 기대된다.

  • All of the people or objects which are contacted during the activity of guard are added to range of objects. guard has to notice decision, question proposal, observation, accomplish to be happened them at the same time recognizing the steps as soon as possible. Before a lot of information of client are shown, guard expert has to search observation of materialization, extension of reservation, notification of business and causes of danger through personal interviews. Rapid communication system has to be assumed and effective caution, protection and shelter and following prevention are cooperated as well as has to care about safe of guard object by a protective wall. And also has to get out of the ground, keep the large shape when moves, prevent the trials of attack from the assassinators after takeing control over weapons.

  • In modern society, there are diverse sorts of VIPs including a king and individuals. Some like a king or president are in need of professional secret services, and others become VIPs by being guarded by a bodyguard company at their own request. The former is called a public guard, and the latter is a private one. In the field of the public guard, the nation should be furnished with a guard system in consideration of political circumstances to protect VIPs. That is, the parliamentary cabinet system and presidential system call for a different guard system, and the guard system's professional features vary to some degree with political situations and cultural climate. If the ultimate goal of guard is to protect the chief of the democratic and open state in a most efficient and safe manner, it's mandatorily necessary to set up a professional and specialized guard organization to provide democratic and efficient secret services. It's desired that the domestic presidential guard division should be staffed with not only expert guards but other personnels dispatched from the military and police. In the police, guard mission is splitted among various guard and security agencies, including the National Police Agency's public security bureau or the Seoul Metropolitan Police Agency's public security division, 101 security unit, mobile police and 22 special guard division. As a chain of command is separated and it's difficult to manage such organizations effectively, the National Police Agency should be exclusively in charge of VIP guard and security. In the area of private guard, the private police system has shared national security task as a middle organization between the private police and private guard. But now its intent has gradually weakened, and its mission should be redefined. In addition, the way people look at private guard should change, and they should be well informed that it could serve to prevent possible crimes, protect them against crimes and get rid of their inconveniences. To make a good impression on people, the guard associations and businesses should put their efforts into reinforcing publicity activities, and the government, academic circles and press should team up with them as well.

  • The automotive front bumper guard is the most important part of the vehicle for protecting the life of driver when a traffic accident happens. In order to ensure safe driving, this part must possess sufficient strength and durability. This study was carried out with structural and fatigue analyses by designing front bumper guard models. After the lowest value for maximum total deformation and equivalent stress was found through structural analysis and the highest value for fatigue life was found for all three models, it was shown that the type C front bumper guard model was the most suitable for application to a real car. The strength property and durability of the optimum design were determined through this study's results.

  • A number of guard lamps are utilized to ensure to safe walking during nighttime. Due to the lack of legal regulations, however, many guard lamps are not installed in organized ways, resulting in the increase of electric shock hazard. In order to establish the legal regulations which can be specifically applied to guard lamps, a research on the actual state of them is performed in this paper. As a result of the research, three regulations are addressed and suggested on equipment installation, management and development.

  • Elimination of dangerous points is the most effective method for safety in mechanical equipments. The next effective method is recognized as isolation and/or safe-guarding of dangerous spots from human beings. With progress of mechanical automation technique such as industrial robots, the need for safe-guard-ins is now being enlarged. It is needless to say that when a machine-guard is designed and installed, a comprechensive understanding of human movement is indispensable. But in this country, there is no scientific for those thems, and no one verifield whether it is valid to apply general guideline such as OSHA's to Korean or not. Further, basic anthropometric items for safety reach standards are neither availble nor included in nation-wide anthropometry project. In this research, human anthropometry data of Korean youngsters are analyzed for safety barrier and safety slit width, and compared with guidelines of other countries-Germany, United Kingdom, Japan, and USA. Though they are standards for safety, since they are based upon their own peoples' data, some of them especially foot reach are not not applicable in this country. It should be notified that careful application of numeric value is very important.
