항공기에 의한 산불공중진화는 지상진화 보다 진화의 효과성이 좋다. 따라서 공중진화는 산불의 대형화를 방지하는데 중요하다. 미국에서는 고정익항공기 및 회전익항공기(헬리콥터)가 합동으로 공중진화를 하나 우리나라는 회전익항공기만을 이용하고 있다. 따라서 헬리콥터에 의한 공중진화의 효과성에 대한 연구가 필요하다. 공중진화의 효과성은 투하되는 물의 분포형태와 범위에 따라서 결정된다. 따라서 본 연구는 산림청에서 운용하는 S-64E, Ka-32T, AS350B2의 3개 기종으로 물투하 실험을 실시하여 유효 분포형태와 범위를 도출하였다. 이 연구 결과로 조종사들이 공중진화의 효과성을 증대시키는데 기여하고자 한다.

본 연구에서는 우리나라 산불현장에서 운영되는 산림청, 소방, 민간헬기의 특성과 배치현황을 분석하였다. 헬기 배치를 통합적으로 살펴보면 충북, 전남이 타 지역에 비하여 산불발생 건수가 다소 많으나 헬기배치의 공백으로 인한 초동진화에 취약하다. 경기도는 산불발생이 비교적 적은데 비하여 헬기가 많이 배치되어 강원도와 비교할 때 불균형적인 배치가 되어있다. 결론적으로 산불조심기간에 일부지역의 편중배치를 일부분 조정하여 지역별로 공백이 있는 취약한 지역에 헬기 배치와 민간헬기를 국비로 임차하여 운영하는 방안의 검토가 필요하다. 더불어 대전, 충북, 전남, 제주 등은 임차예산을 확보한 헬기 배치가 필요하며 특히, 대전은 소방헬기 기지 개설도 필요할 것으로 사료된다.

The pre-hospital care in site transportation care and site care will be divided, it will follow in site or evacuation it will enforce it will can evacuate in condition of the emergency patient of like this at the initial stage and emergency care from inside fire fighting helicopter back transfer means and the manpower security of the specialty emergency necessary personnel(nursing and 1st EMT's) as the medical treatment agency and modernization of first aid equipment necessity inside American securing and fire fighting helicopter and specialty first aid packet won about lower the emergency care which is appropriate cannot become accomplished are the actual condition in total lack of emergency care equipment. Consequently craving augmentation, in order to be adapted with the handling kind transfer whose specialty and is appropriate and present time of rapid increase and the citizen of emergency demand by fire fighting helicopter simplicity transfer compared to it is a condition where the countermeasure preparation is earnest. Must expand emergency care equipment first even in fire fighting helicopter and 1st EMT's which it follows in him become arrangement and quickly the execution and specialty temporary disposal(ALS) must be enforced a temporary disposal and must buy the life which is. Also it gets by experience a helicopter induction outline, a radio communication method and the patient helicopter on-board hour attention point back various attention fact back with the body and when where it stands but accurately there must be it will be able to induce the helicopter. Also every manuals anger it does a helicopter transfer method and the emergency care method back and that all processes must do fixed form anger, it becomes feed. Also it related with a helicopter transfer even from the relationship agency many research to lead, difference of the advanced foreign nation and the maximum it is the actual condition where the medical emergency system construction which it reduces is earnestly demanded. Also with emergency structure(crane) it confronts to an aviation transfer even from the establishment college and education it leads intensively and 1st EMT's of the good quality which relates with an aviation structure expects is cultivate at all.

Not only in Korea, but also in other countries, most helicopter accidents occur at low altitude. Analysis on accidents data collected both in Korea and other countries has brought two conclusions. Firstly, helicopter operations during the night hours carries a high risk. Secondly, the most common cause of night hour operations is loss of control due to the flight illusion. As an operation relying on a night vision in particular has a very high accident hazard, accompanying instruments such as NVG are ought to be provided. Hence, a thorough preparation and inspection on missions for night forest fire extinguishing should be required and perfect guidelines/road maps and enough training programs for the operation should be provided before the engagement in missions.

Nowadays many peoples are using helicopter in various fields, not only military use but also common people applications such as air-measurement, photography, transportation of goods and persons, saving life and fire fighting etc. And it will be expected more popular than now. Most important part of helicopter to increasing performance and to reducing noise is rotor hub-system. Hub system consists of rotor-blade and rotor-hub. We participate to develop next-generation rotor hub system with elastomeric bearing, part of rotor hub. In this paper we introduce about the role and shape of elastomeric bearing in next-generation helicopter hub system. Then we study about bearing-material requirements and measuring methods. Finally we represent some experimental results.

본 연구에서는 산불이 발생하면 대형화 위험성이 증대하여 항공기 특히, 헬기의 산불진화 활용성이 점차 증가되고 있는 관점에서, 산불진화 과정 중 헬기에 의한 공중진화기술과 안전성 향상은 효율적인 산불진화의 성공요인으로서 매우 중요하다. 따라서 우리나라 산불전문기관인 산림청 산림항공본부의 조종사들에 대하여 산불현장에서 실제 경험한 내용을 토대로 설문조사를 실시하여 효율적인 공중진화기술 및 안전성 향상 방안을 제시하였다.

The east coast of the Korean Peninsula is susceptible to fires because of the low rainfall in winter and spring, and large forest fires have occurred in this area. Lack of fresh water to combat fires has hampered efforts to prevent widespread forest fires in this region. Seawater has not been used as a suppressant because of possible detrimental effects of salt. We investigated the mobility of saline water in the forest soil and their effect on the microbial activity. Using a fire-fighting helicopter, seawater was sprayed over three plots (50 × 100 m) located on the eastern slope of the Baekdu mountain range in South Korea in April, 2011. We sampled the soil in April 4, May 20, and August 5 to determine the amount of salt that remained in the soil. The electrical conductivity value of the soil decreased to <400 μS/cm over a 1-month period. Approximately, four months after the application of seawater, the electrical conductivity value and Na⁺ content in all treatment plots did not significantly differ to those of the control plot, and total microbial activity also recovered to that of the control. Our results indicate that the amount of rainfall, soil physical-chemical properties, and topological factors may be a critical factor determining the mobility of saline water in forest soil.

본 연구에서는 목조 사찰 화재시 펌프(물탱크)차의 현장 도착 가능여부에 따라 사찰화재 유형별 진압대책을 4가지 유형으로 분류하고, 각 유형별 화재진압 전술 및 방법을 도출하였다. 연구결과, 펌프(물탱크)차의 접근 및 소방용수 확보가 가능한 사찰은 일반 건축물화재 진압전술을 적용하지만, 그렇지 않은 경우는 헬기, Water Bag, 연계급수 집중 진압전술, 무선통신을 이용한 소방차 수위 자동전송 System 및 급수낭을 활용하고, 사찰 인근 소방서에 화재진압 장비(동력펌프, 호스, 노즐, 급수낭 등)를 적재한 일반 4륜구동 차량 배치와 A자 사다리를 활용한 진압대책 등이 필요한 것으로 나타났다.

It was because mankind could use the fire that we have been civilized. creating a brilliant culture and developing an industrial society. While fire is very useful to our life, the number of the victims of fire continues to increase, This study suggests the ways to rescue the people safely when they are subject to a fire in a high-rise building. To this end, the concept of fire is reviewed. Fire breaks out when the conditions for congestion are met, and therefore. if any of the conditions can be blocked, the fire will be extinguished. In other words. the knowledge of such conditions will greatly help the fire fighters to rescue the people, and so. such conditions for congestion as flammable, heat, oxygen and chain reaction are examined. In addition, the effects of such by-products of fire as heat and smoke on human body are reviewed. In order to rescue the people more safely, the fire fighters are requested to review the situation and design a rescue strategy before being engaged in a full-scale rescue activity. This study discusses various rescue methods using such passages or equipments as stair case, double ladder, special fire fighting vehicle, elevator, jumar, rope, helicopter, etc. In conclusion. since it is more difficult to rescue the people from a high-rise building than from the ground, it is essential to design a rescue program not after fire but before it and thereby, minimize the number of victims.
