국내 문화 예술 산업에서 게임과 관련된 음악 혹은 OST가 드라마, 영화, 애니메이션 등의 타 장르와는 다르게 국내의 미디어 매체에서 언급과 노출이 비교적 적은 편이다. 게임을 소비하는 일부 이용자를 제외한 일반적인 대중은 게임 음악을 접할 기회가 많지 않기 때문에 게임 음악은 여전히 문화 예술이 아닌 게임 음악이라는 틀 안에 갇혀 있다. 본 논문에서는 국내 온라인 게임과 관련된 음악의 상업성에 대해 분석하고 게임 음악이 하나의 음악 장르로 자리를 잡기 위한 방안을 제시하고자 한다.

In many countries, secondary school science is no longer solely for those destined for careers in science, medicine or engineering and both boys and girls study biology, chemistry and physics. In Japan, secondary science has been studied by boys and girls as a compulsory subject since the establishment of the modem school system in the late 19th Century. However, although 'science for all' is becoming the norm, it appears that science is less popular with girls than it is with boys, and that lower-attaining students are not adequately catered for in Japan and elsewhere. In this paper, the author investigates gender issues in the secondary science curriculum and examines the curriculum for future scientists using a historical perspective and focusing on the case of Japan. An analysis of two historical issues, gender and the curriculum for future scientists, found that, firstly, the science curriculum needs to contain a clear statement of its aims, and, secondly, that the secondary science teacher is one of the most important factors influencing science teaching particularly for girls. ost important factors influencing science teaching especially for girls.

In order ti find out the optimum seeding time(OST) and optimum seed rate(OSR) of Italian ryegrass on seed production, this studies with tetraploid cv. Tetrone were carried out on the experimental field of Livestock Experiment Station. Treatments included seed rates of 1, 2, 3 and 4 kg per 10a and combined with seeding time on 20, 30 Aug, 9, 19 and 29, September 1983. Seeds were sown in rows 50 cm apart and were spaced in a continuous line with width of 15 cm within the rows. The results are summarized as follows: 1. Autumn tillers could be classified into three groups from winter-killing point of view, namely winter-killing completely, damaged growing point only and living tillers. 2. The young inflorescence-bearing stem in Italian ryegrass which were sown earlier than 9. September were more susceptible to winter killing. Tiller buds in those stems which originated from an axillary buds at the stem base within senescent leaf-sheaths emerged lately in spring, and consequently heading was delayed, culm length shortened and seed yield reduced. 3. Tiller buds which originated from damaged growing point only and living tillers in moderate shoots emerged early in spring and those tillers became mainly spike-bearing culm. 4. The emergence-time of tillers influenced on culm-, spike- length and ripenness more than seeding time and seed rate. 5. Seed yield was mostly affected by the number of spikes per unit area. 6. For the safety of over-wintering and enough spikes on seed production, OST and OSR at Suweon were the last part of September and 2-3 kg per 10a, respectively. Especially OSR was 2 kg per 10a for early and 3 kg per 10a for late OST.

The current international legal system does not provide a safeguard against the militarization and the weaponization of outer space. Although the term "peaceful use of outer space" in the 1967 Outer Space Treaty(OST) appears in official government statements or in multilateral space treaties, it is still without an authoritative definition in reviewing national practices. The ambiguous ban on weapons in Article IV of the OST allows countries to loophole on the deployment of other weapons other than nuclear weapons. Meanwhile "Draft Treaty on the Prevention of the Placement of Weapon in Outer Space and of the Threat or Use of Force against Outer Space Objects(PPWT)" to Conference on Disarmament (CD) commissioned by the UN General Assembly's Special Session jointly submitted by China and Russia in 2008 and later revised in 2014, attempting to define and prohibit the proliferation of weapons in outer space and provided definitions of prohibited weapons, are opposed by the US on the grounds that currently there is no arms race in outer space. Some experts support a hard law approach in which binding laws aimed at ultimately creating integrated and binding legal instruments in all aspects of the use of outer space should be adopted to regulate the military use of space. However as a temporary measure the soft law guidelines should be developed for the non liquiet, a situation where there is no applicable law. The soft law could be used to create support for the declaration of the treaties and to create international customary law. For example, the 1963 Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space that regulates the activities of the state in the exploration and use of the universe, and the 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space will illustrated. While substantial portions of the former was codified later in the 1967 OST, the latter which, although written in somewhat mandatory terms, have been consistently complied with by states, have arguably become part of customary international law. On November 12, 1974, the General Assembly reaffirmed that the development of international law may be reflected inter alia, by declarations and resolutions of the General Assembly which may to that extent be taken into consideration by the International Court of Justice.

Since USSR successfully launched its satellite "Sputnik"in 1957, many countries including US and USSR began military use of space, and engaged in arms race in space, which is against spirit and ideals of peaceful use of space as common heritage of mankind stipulated in many treaties such as Outer Space Treaty. With worsening Cold War between East and Western Bloc, this military use of space and arms race in space has been intensifying. Regarding the ideals of peaceful use of space, it is interpreted that military use of space is possible unless it does not have the purpose of aggression. The military use of space may have diverse forms such as attacking satellites in space, or attacking from satellites, making use of present and future technologies available which should include the use of nuclear and kinetic/hyper-speed weapons, laser, particle beams, near explosion, disturbance weapons in different directions (i.e., surface to space, space to space, and space to surface). Arms control is being implemented by the efforts of many countries in different formalities including legislature of international treaties under the auspices of UNCOPUOS and prohibition of weapons of mass destruction. Taking outstanding examples aiming at arms control by international community, there are confidence building measures (CBM), strengthening implementation of existing treaties, partial ban of nuclear tests, countryand regional approach, comprehensive approach and measures having legally binding force. While U.S. has surpassed other countries concerned in the area of military useof space, it withdrew from OST in early 2000s, thereby raising concern of international community. It requires concerted efforts of cooperationand implementation by international society to make sure peace of mankind and environmental conservation through arms control in space. Observing de facto possession of nuclear weapons by North Korea following series of nuclear tests and launching satellites, and efforts of launching rockets by South Korea, it is strongly needed for both countries to take part in arms control efforts by international community.

Offshore CCS technology is to transport and inject $CO_2$ which is captured from the power plant into the saline aquifer or depleted oil-gas fields. The more accumulated injected $CO_2$, the higher reservoir pressure increases. The increment of reservoir pressure make a dramatic change of the operating conditions of transport and injection systems. Therefore, it is necessary to carefully analyze the effect of operating condition variations over the injection period in early design phase. The objective of this study is to simulate and analyze the $CO_2$ behavior in the transport and injection systems over the injection period. The storage reservoir is assumed to be gas field in the East Sea continental shelf. The whole systems were consisted of subsea pipeline, riser, topside and wellbore. Modeling and numerical analysis were carried out using OLGA 2014.1. During the 10 years injection period, the change of temperature, pressure and phase of $CO_2$ in subsea pipelines, riser, topside and wellbore were carefully analyzed. Finally, some design guidelines about compressor at inlet of subsea pipeline, heat exchanger on topside and wellhead control were proposed.

The box-counting(BC) method is one of the most commonly used methods for fractal dimension calculation of binary images in the fields of Engineering, Science, Medical Science, Geology, etc due to its simplicity and reliability. It deals with only square images with each size equal to the power of 2 to prevent it from discarding unused pixels for images of arbitrary size. In this paper, we presents a more efficient BC method based on the original one, which is applicable to images of arbitrary size. The proposed approach allows the number of the counting boxes to be real to improve the estimation accuracy. The mean absolute error performance is computed on two deterministic fractal images whose theoretical dimensions are well known to compare with those of the existing BC method and triangular BC method. The experimental results show that the proposed method can outperform the two methods and assess the complexity of coastline images of Korea and Chodo island taken from the Google map.

"The art challenges the technology, and the technology inspires the art." By this word John Lasseter expressed Pixar animations main soul of story. Media technology has a close relation with the animation. As media developed more and more, an animation has been widen a lot and have given new visions to the audiences. We can see such this figure from the history of the Disney animation. They had tried to make all the kind of animations such a silent animation, planetary animation, black and white animation and the multi colored animation. Lately Disney had made animation that has traditional style. But the method of making traditional animation stable side story's holdup the audience. So Disney animation decided to change this method. For the result of Disney animation studio effort Frozen had produced after a computer graphics work following Rapunzel. What was the reason for entertain well of Frozen? Not only changing the method of producing traditional to computer graphic is could not make entertain well. We can see from the Frozen concordance of the original idea and modern scenario, OST the perfection of computer graphics work. In this paper work Disney animation has worked from the silent animation to computer graphic works result of "The Frozen". For the contribution of technology development makes able to analyze animations expression and relation. There is a lot shots that hard to analyze in the Frozen. But I will study it with the method named "Expansion in space" to making main analyzing expressive extension that appears on the scene.
