Because of the global warming, the Arctic Ocean is expected to be ice-free by the year 2035. When the Arctic Ocean will be opened, a number of national interests will become more salient as experiencing a shortened sailing distance and decreasing navigation expense, possibility of natural resources transport by sea from Arctic Circle, and indirect-profit making by building a herb port in Asia. To secure the national interests and support the free activities of people in this region, R.O.K government is trying to make advanced policies. In order to carry out the naval tasks in the Arctic Ocean, using the operational characteristics(mobility, flexibility, sustainability, presence of capabilities, projection) is necessary. To this end, ROK Navy should analyze the operational environment (O.E.) by its capability(weakness and strength), opportunity, and threat. R.O.K. Navy should make an effort over the following issues to implement the tasks in the Arctic Ocean: first, Navy needs to map out her own plan (Roadmap) under the direction of government policies and makes crews participate in the education·training programs in home and abroad for future polar experts. Third, to develop the forces and materials for the tasks in cold, far operations area, Navy should use domestic well-experienced shipbuilding skills and techniques of the fourth industrial revolution. Next, improving the combined operations capabilities and military trust with other countries in the Arctic region to cover the large area with lack of forces' number and to resolve the ports of call issues. Lastly, preparation in advance to execute a variety of missions against military and non-traditional threats such as epidemics, HA/DR, SOLAS, in the future operation area is required.

The Korean peninsular is a typical mountainous terrain country which has 75% of mountains with having featuring of east-high west-low and north-high south-low type. Though the physiographic feature is not changed, the future operational environment has been frequently changed through artificial transformation by people living in the city. While Korea has been changed continuously since 2000, 90% of Korean territory has been urbanized and the majority of people live in the city. In particular, in the case of combat in urban area, there might be lots of limitations because of confusing with millions of people and complex buildings. The combat commanders should make an effort to overcome such difficulties through detailed IPB(Intelligence preparation in the battlefield) considering various situation before planning for major operations. They should change warfighting concept and paradigm. This paper finds the normal characteristics of urban operation and physical traits of the Korean peninsular. As the urbanization has been accelerating in Korea, practical implications about how to prepare the urban operation are discussed.

Cyber attacks on the aviation weapon system, a state-of-the-art asset, have become a reality and are approaching as a constant threat. However, due to the characteristics of embedded software of the current aviation weapon system, it is managed and operated without connection to the network in peacetime, so the response management to cyber attacks is relatively weak. Therefore, when a cyber attack becomes a reality, it is urgent to prepare and evaluate measures for the adverse effects that such attack will have on the execution of the Air Tasking Order(ATO). In this paper, we propose a framework for operational impact assessment in order to avoid confusion in ATO execution and systematic response to cyber attacks on aviation weapons systems. The proposed framework is designed to minimize the negative impact on operations against cyber attacks that may occur under no warning by analyzing the impact on air operations for each aviation weapon system and standardizing countermeasures for this. In addition, it supports the operational commander to make a quick decision to command for the execution of the operation even in a situation where a cyber attack occurs.

Recently, Population has been concentrated in cities due to rapid economic growth. As a result, urban buildings are becoming more dense, high-rise, and diversified. The shape of these urban buildings increases the risk of fire, accidents and crime. The narrow living space has the characteristic of the unchanged floor. In case of a fire, the living space of the narrow residence is large in the damage because the smoke diffusion rate is fast. The radio wave transmittance and transmission distance of wireless communication used in fire fighting operations vary depending on the type of building materials and buildings. Therefore, this paper analyzes the building materials and structural characteristics of the narrow residential space for efficient fire fighting operations. We have developed a communication environment solution for a narrow residential space for the optimal fire fighting operation through the measurement of the radio wave transmittance and the transmission distance of the wireless communication.

To Republic of Korea in the Indo-Pacific region, the stability and prosperity of the area are directly coupled with national survival, interest. Currently, on account of strategic competition between U.S.A, and China in this area as well as supranational·non-conventional threats, the security environment is unstable, required joint/allied responses. So, lots of states inside(U.S.A., Japan, ASEAN, etc.), also, out of this Indo-Pacific area like EU-NATO, open their own strategy related in Indo-Pacific issues to be involved. R.O.K. government took its own line with publishing self strategy following this international trend, it can be shown korean government's strong intend to join in the pending security issues in this region with 'strategic clarity'. Now, R.O.K. Navy has to back up governments, policy. First, R.O.K. Navy should strengthen the relationship inside and take part in the multilateral cooperation of security. Second, to convey this deterrence message to potential threats, Navy is required to show of forces and have combined exercises. Also, as naval forces of advanced countries, Korea, Navy should be taken action in non-traditional threats, and help developing states improve their sea power. To fulfill this tasks in the wide ocean area, Navy need five inherent characteristics(mobility, flexibility, sustainability, capability of presence and projection). In the end, this paper propose the development plan following operational environment (SWOT) analysis as well.

전통적 유방염치료에서 변화는 현대적 우유생산 설비인 덴마크의 연구로부터 나온 결과와 문헌적 고찰을 배경으로 논의된 것이다. 덴마크의 전통적 농장운영제도는 전통적 농부들의 현대화와 1987년에 변화 시킨 정부의 규제법규로 제도화된 것에 의하여 근본적인 형태의 목표로 특성화되어 진다. 모든 질병은 품종, 우사 설비, 사료공급과 경영작전을 통하여 예방되어지는 전통적 농장운영체제에 대한 지침에 의존되어야 하였다. 치료의 농가 선택에 대하여 특별히 관심을 둔 정부규칙은 1. 모든 의학적 예방은 금지된다. 2. 의학적 치료에 뒤 따르는 배출시간은 전통적 농장운영에 비하여 3배가 연장된다. 3. 모든 치료는 수의사에 의하여 수행되어야 한다. 연구는 예방과 치료작전에 초점을 맞춘 전통적 농장운영체제에서 수행한 것이다. 이 과제에서 몇 가지 유방염은 농가자신의 치료로 설명되었으며 그 내용은 다음과 같다. 각 목장에서 유방염은 마싸지 시행과 캠퍼(camphor)또는 페퍼민트오일(pebbermint oil)의 국소응용 그리고 어떤 목장은 동종 요법적 치료(同種 療法的 治療 = Homoeopathic treatment)로 손착유로 하고 농가자신이 치료하였다. 이 결과에서 농부자신의 치료와 수의사 치료가 보여 준 것은 성공 사이에 유의한 차이가 없다. 변화와 전통적 치료에 추가하여 비의학적 치료가 검토되었다. 유방염 건에서 농부 대 수의사 역할은 유방염 문제점이 있는 목장에 근거하면은 똑같다고 검토되었다. 동종 요법적 치료의 문헌연구는 경험을 통하여 수행되어진 것이다. 현 과제는 목장의 치료작전 안에서 종합되고 있는 동종 요법적 치료의 실제적 현상이 설명되고 있다 동종요법은 어떤 건에서 반응이 제안될 수 있는 유방염치료와 관계되는 치료 방법이다. 그러나 덴마크의 경험에서 전통은 유방염 건에서 치료의 선택에 영향이 있을 것이라는 것으로 비교적 제한되어 있다 이 치료에 대한 원리의 배경을 검토하였다.

The purpose of this study is to examine cinematic representations of places in the Korean War films on the event of 1950 'Incheon Landing', focusing on the place representations. 'Incheon Landing' of September 1950 provided a turning point for the Korean War, and the event can be interpreted totally different from the South Korean and the North Korean perspectives. Two films on the same event of the 'Incheon Landing' - a South Korean film, "Incheon Landing Operation"(1965), and a North Korea film, "Wolmido"(1982)- were selected as major sources of analysis and comparison. each director has different intentions. One film was taken from the landing army's viewpoint, whereas the other film was taken from the defender's viewpoint. As a result, one film emphasized the battle as a spectacle of glorious victory from the landing army's viewpoint, while the other film glorified those soldiers killed in the battle as heroes from the defender's viewpoint.
