According to careful study on the COLREGS, 1972, we can easily find out a main point that is to eliminate risk of collision at sea through exercising due regard to all danger of navigation and collision and to any special circumstances including the limitation of the vessels involved, or precaution which may be required by the ordinary practice of seamen. This paper, therefore, aims to clarify legal concept concerning the risk of collision so as to easier assimilate and understand by all mariner before being presented with a situation of danger in realty. After such a forethought and understanding the mariner will be in a position timely to implement the due regard or precaution to avoid collision by himself. For the purpose of good guidance, comprehensive legal practices of collision avoidance are adequately summarized by foreign and domestic cases.

Recently, the danger for radioactive materials has become a hot topic. Beginning with the Chernobyl nuclear accident in 1996, in 2011, the Fukushima nuclear power plant in Japan suffered major damage such as large-scale casualties and radioactive dangerous area selection. Concerns about leakage of radioactive materials due to recent earthquakes have been deepening in Korea, such as Wolsong Nuclear Power Plant in Gyeongju, and there is a growing interest in the safety of radioactive materials through the media and the media. However, the route to exposure to radioactive materials is not limited to these large-scale nuclear accidents. Typical examples of this are radioactive substances exposed in daily life. In the case of radon gas, the danger is being revealed through current events programs and news, and natural radiation exposure is attracting attention.

A defect on the product safety display is defined by a failure to prevent the damage caused by the inappropriate explanation, direction, and caution to warn the users of the related risks. In other words, it lacks the sufficient instructions or caution for proper use and is unable to furnish the possible danger of the product and the instructions to deal with it. The defect is the responsibility of the manufacturers who are supposed to provide the adequate information so as to prevent injuries of the users. However, in order to prove the product safety display defective, there should be a comprehensive consideration in many different ways such as social norms (such as property and expectation of the product), usage form, indication of the expected risk, and awareness of consumer about the harm and possibility of avoidance of danger. The purpose of this research is to propose the content and types of standardized indication of safety in the industrial product by collecting and analyzing domestic safety information.

It compared subcontractor with contractor that are wages, the labor hour and labor condition of the work environment back are inferior relative. The subcontractor which basically the contract workers evade the dangerous process or the difficult work, the dirty work back what is called 3D the case which does to keep a business is many. so With life it will be threatened consequent health directly. The possibility where the subcontractor will be exposed to danger work came to be high. Consequently it prevents the subcontract which danger work is insensitive from this research and immediacy of the subcontract workers who is weak hygiene circumstance complement the plan it will be able to secure the immediacy safety&health subcontract workers, substantially to prepare in the hazard subcontract proprietor. Thus, this paper aims at presenting countermeasures to substantially secure safety and health of subcontractors by preventing ill-advised subcontracting of harmful and hazardous operations and imposing partial occupational safety and health responsibility to employers to enhance safety and health environment of subcontractors.

The modern society is changed into mass production, complicated circulation society and mass consuming society because of the development of the fast science technology since the occurrence of the industrial revolution. Also, the human life style is changed into the abundant consumption society because of the appearance of the various products. The society change like the above provide comfortable life to us. but We are facing with danger for the bad food, illegal medicines and bad products. So, To solve the danger like the above, The Product Reliability Law be made. The both The enterprise and consumer need The Product Reliability Law to protect one's own interest. The consumer is claiming to use the product of safety of the resonable price and good quality in modern society, So, 1 studied on countermeasures of domestic enterprise to increase the competitive power of the enterprise according to Product Reliability Law

In this paper, we proposed a method to display a hazard warning of hacking in the UX(: User Experience) concept level for non experts in the open Wi-Fi access area. According to the dangers of the AP raised by capture, we developed an application that provides a warning pop-up on the danger of hacking before using for APs that are distinguished by color and selected.

Safety and health problem are essential element of enterprise productivity Innovation within 21th century Global struggle for existence. It is not only to protect workers but it also should prevent workers from various forms of danger. In this paper, specifically, through Case Study about safety and damage government official System course danger exclusion technique of physical distribution, I wish to present direction of continuance possibility management hereafter.

If we don't know the intention of altering course of a target ship when being in a head-on or a crossing situation, we may be confused about our decision making to change our course for collision avoidance and be in a danger of collision. In order to solve these problems, we need to develop an automatic detection system on altering course of a target ship for efficient collision avoidance. In this paper, we proposed an early detection system on altering course of a target ship using the steering wheel signal. This system will contribute to the reduction of collision accidents and also be used to the VTS system and the analysis of marine accidents.

This paper describes the system for detecting the tank crew's(loader's) hand, arm, head and the upper half of the body in a danger area between the turret ceiling and the upper breech mechanism by computer vision-based method. This system informs danger of pressed to death to gunner and commander for the safety of operating mission. The camera mounted ort the top portion of the turret ceiling. The system sets search moving object from this image and detects by using change of image, laplacian operator and clustering algorithm in this area. It alarms the tank crews when it's judged that dangerous situation for operating mission. The result In this experiment shows that the detection rate maintains in $81{\sim}98$ percents.

Colorimetric chemosensors are now considered as one of the most effective analytical method used in the environment monitoring. Colorimetric chemosensor for pH sensing can easily detect the primary danger or change of the surrounding environment pollution and source of infection and can prevent danger in the various fields. Quinaldine and Indole based colorants having the function of colorimetric chemosensors were synthesized and applied to textiles by the LBL method and electrospinning. The characteristics of colorant containing nanofibers and colored textiles were investigated if they can be used as environmental monitoring chemosensors.
