Purpose: According to the Occupational Safety and Health Act of the Ministry of Employment and Labor, in order to prevent industrial accidents, the right to stop work must be exercised in the event of an imminent danger. This study conducted a fact-finding survey on whether employers fulfilled the right to suspend work in the workplace when an imminent danger, such as a typhoon, was encountered. Method: For two days from August 9 to October, when the impact of Typhoon Khanun No. 6 was significant, it was confirmed by wire whether or not the work suspension was carried out at the workplace, and the subjects of the survey were 1,649 construction sites, 830 manufacturing sites, and 278 other industries, for a total of 2,757 sites. Result: As a result of the fact-finding survey, 56% (1,555 locations) on August 9th and 77% (2,142 locations) on August 10th carried out full or partial work suspension. In particular, on August 10, when the typhoon landed, 40% of all workplaces completely stopped work. Conclusion: Through this study, it was confirmed that the right to suspend work by employers is being used in actual workplaces. In the future, when there is an imminent danger, in addition to the right to suspend work, flexible and telecommuting, working hour adjustments, etc. must be actively used to ensure the safety of workers and protect their lives.

많은 선박 사고에서 해상 조난자를 수색 및 구조하는데 매우 많은 시간이 소요되며, 수중에서 체온저하 등으로 적정 시간 내에 구출되지 못한 조난자의 경우 사망 위험이 매우 높은 실정이다. 이러한 위험을 줄이기 위한 기존 기술로는 발광막대, SOS 부이, SART, EPIRB 등이 있으나, 급박한 상황에서 개인이 활용하는 데에는 한계가 있다. 이에 따라, 이러한 문제를 해결하고 효율적인 수색 및 구조 활동을 위한 새로운 방법을 연구하게 되었다.

산업이 발전함에 따라 지적재산권에 대한 가치는 점정 중요해지고 있고, 기업의 흥망성쇄를 결정짓는 가장 큰 요인중 하나로 자리잡고 있다. 엄청난 비용을 투자하여 사업화하고 있던 세계 굴지의 기업들도 경쟁회사의 핵심특허 단 몇 건만으로 순식간에 몰락하는 경우도 발생하고 있다. 이제 지적재산권은 살아남기 위한 유일한 방어수단이자 공격수단이 되었다. 이와 같은 급박한 상황하에서 각 기업은 경쟁회사의 지적재산권을 분석하고, 이를 통해 자사의 연구개발 전략을 수립하기 위해 노력하고 있다. 그러나 이와 같은 분석작업은 다수의 전문가 일지라도 상당한 시일이 소요되는 방대한 작업이며, 이를 자동으로 실행하기 위해 많은 소프트웨어 회사들은 Clinent base 특허분석용 툴과 Web base site를 개발하여 서비스를 하고 있다. 그러나 이들 종래의 특허분석용 툴과 Web site들은 특허에대한 정량분석 정보와 정성분석 정보를 제공하지만 해당 특허가 기술분야에서 얼마나 영향력을 미치는 객관적으로 제시를 하지 못하고 있다. 본 논문에서는 개술 개발시 해당 분야의 특허 기술의 흐름을 빠르게 파악하고 동 기술 분야에서 영향력이 있는 특허의 랭킹을 제시하여 기술 개발시의 위험성을 줄이고자 하는데 그 목적이 있다. 이에 특허 출원시 인용했던 선행특허들의 인용 관계를 분석하여 특허간 연관관계를 규명하고, 각 기술 분야에서 영향력이 높은 특허를 찾는 방법과 시스템을 제시하고자 한다.

The Steering and Sailing Rules of International Regulations for Preventing Collisions at Sea now in use direct the best aid - action to avoid collision by the stand - on vessel. But these rules do not refer to the safety relative distance between two vessels when she should take such action. In this paper, the author analyzed the ship's collision avoiding actions from the viewpoint of ship motions and worked out mathematical formulas to calculate the relative distances necessary for taking action to avoid collision. Figuring out the values of maneuvering indices through experiments of 11 actual ships of small, medium, large and mammoth size, the author applied these values to the calculating formulas and calculated the minimum relative distances. The main results are as follows: 1. It was confIrmed that the stand - on vessel should keep the greatest relative distance for taking best aid - action to avoid collision when the cross angle of course was $90^{\circ}$ and near it(70-$90^{\circ}$ ). 2. When the cross angle of course was $90^{\circ}$ , the minimum relative distance of small vessel(GT: 160-650tons) was found to be more than about 6.8 times of her own length, and those of medium(GT : 2,300-3,500tons), large(GT : 22,OOO-62,OOOtons) and mammoth(GT : 91,000-139,000tons) vessels were found to be more than about 9.0 times, about 5.4 times and about 6.8 times of their own lengths. 3. It was confIrmed that collision danger was greater when crossing angle was obtuse than in an acute angle, therefore greater relative distance was to be kept by the stand - on vessel for taking best aid - action to avoid collision in the case of the obtuse angle. 4. In every vessels, in the case of $90^{\circ}$ cross angle of course the safety minimum relative distance was found to be more than about 9.0 times of their own lengths.

Making proper judgements in urgent situations facing a submarine at the sea is very critical. This is because the commander's misjudgments could drive the entire ally to destruction in a moment. In order to generate appropriate tactics on behalf of the human commander and to analyze the effectiveness in such emergency situations, studies using intelligent agents and genetic algorithms have been conducted. In this study, inference engine based intelligent agent is adopted to each warship and submarine to generate optimal tactics on the variable environment with genetic algorithms. And we analyze the risk of the alliance according to the performance of the enemy submarine through a simple simulation and generate appropriate tactics using the genetic algorithm. Also generated tactics are evaluated and the results are analyzed to figure out why such results are formed.

In Korea, exposure to stress has been accompanied by mental pain in the process of achieving many growth along with rapid development, various social problems, and the frequency of emergency hospitalization is increasing.. In the case of mentally ill patients, "unwanted hospitalization" is a problem, and police and 119 paramedics try to suppress the body of mentally ill patients, and many problems are exposed This is because the constituent requirements of the provisions of emergency hospitalization under the Mental Health and Welfare Act do not reflect reality, and each institution has a different position on one mentally ill person, and emergency hospitalization does not proceed smoothly or leads to friction between related organizations, and the safety of the mentally ill or others is not secured. Emergency hospitalization is defined as "a person who finds a person who is presumed to be mentally ill and is at high risk of harming his or her health or safety or others," and if the situation is so urgent that he or she cannot afford time to go through the hospitalization procedure to decide on his or her own hospitalization, he or she can request emergency hospitalization with the consent of a doctor and a police officer. In this case, 119 paramedics are escorted to a psychiatric institution. This provision of emergency hospitalization poses many problems in the process of transferring to psychiatric institutions. If a police officer or 119 paramedics in charge of practice use "physical force" during the emergency hospitalization process, side effects will inevitably occur, and professional negligence can be a problem. Specifically, when exercising physical force, the minimum necessary physical restraint based on laws and regulations and proportional principles is required, and the lack of the duty of care of 119 paramedics or police officers under the laws and regulations will eventually be resolved by applying other laws and regulations. Accordingly, it will be an opportunity for mentally ill patients to be transferred to psychiatric institutions in a safe environment by changing the subject of emergency hospitalization provisions under the Mental Health Welfare Act, defining and prescribing the use of physical protection guards as the enforcement regulations of the Mental Health Act, setting the duty of care for 119 paramedics and police officers, and creating an environment for transportation so that mentally ill patients can be treated safely.
