The exhaust wake of an aircraft engine is discharged in a high temperature and high speed, which can damage objects such as an aircraft in the rear. The exhaust wake can lift small foreign substances lying on the ground or falling off, and the floating foreign substances can enter the intake duct of the aircraft moving from the rear and cause engine FOD (Foreign Object Damage). This study experimentally analyzed how the engine exhaust wake generated from military jet fighters affects the movement of foreign substances and evaluated the effects of foreign substances on the damaged area by measuring wake velocity. The simulation and field experimental results confirmed that the effect of exhaust wake increases as the rear position closer, and that foreign substances lifted by the wake can act as FOD to the adjacent rear aircraft.

The purpose of this study was to investigate and evaluate the state of School Forest Movement by the School Forest Committee of the ‘Forest for Life’, and to provide schools and social communities with alternative, for activation through foreign and domestic case studies. School Forest Movement is very important and has great effect on many aspects, such as the improvement of school environment, the expansion of environmental education in school, the enhancement of local membership and increasing participation of school community. School Forest Movement has expanded from 10 schools in 1999 for pilot implementation to 20 in 2000. Now, it Is broadly recognized that the movement should be expended nationally A few problems were observed through pilot implementation. School community has little consensus away member and hardly participates in the movement, and the process is often underestimated, comparing to the result. For activation of School Forest Movement, school community should be cooperate to local community. Especially, the stepwise execution of School Forest Movement should be well organized and School Forest Movement should be changed into a process-oriented movement for more participation of school community including students, teachers, parents and.

Materials produced with the help of new technology are used in the design of materials used in all science and engineering departments today. A sports engineering and sports equipment department is one of these departments. The use of nanotechnology in sports equipment is one of the most popular uses of this technology today. Nanomaterials have been used in sports equipment for many years, and reputable companies have benefited. Athletes' equipment allows them to display their skills to the fullest extent. It has always been a dream of professional athletes and their coaches to have unique equipment. As a result, engineers have spent all their time and effort solving this problem. Science and engineering can do various things to meet the needs of all sports levels, including specific and detailed designs, the use of appropriate materials, and standardization tests on equipment. However, these aspects must remain aligned with the latest technologies as they develop, just as with other sciences. These technologies, especially nanotechnology, are essential to sports equipment and devices developed today by sports engineers. This article examines the balls that use nanotechnology and can also improve the athlete's performance by using this technology in a specific structure. Using nanotechnology to make nanocomposite poly-hope balls, which makes them lighter and more acceptable, reduces the impact on the ball and increases its movement speed.

Throughout the twentieth century, American furniture was subject to a number of influences-both domestic and foreign. Especially, in the first half of the twentieth century, there were strong foreign influences compare to the later half of the century. Therefore, this study aimed for discussing foreign influences and for addressing issues such as attitudes toward materials, ornamentation, and technology. As a result, this study suggests how American furniture becomes instinctive moving away from strong foreign influences from the second half of the century. The twentieth century was a period of rapid and dynamic change for American furniture design. In many ways, the designs throughout the century were reflective of the social, political, and economic culture of the time. With the birth of the modern movement in Europe and a strong influx of foreign immigrants, American design in the first half of the century was characterized by a reliance on European and foreign influences. However, after the two world wars, strong domestic influences came into play. The two world wars provided the essential catalysts for change: new materials, developing technology, and changes in life style and consumer values. A historical examination of design trends and individual designers illustrates how American furniture design evolved during this period.

The purpose of this study is to grasp foreign worker's industrial safety and health state, which find out the improvement to secure the basic safety net for foreign workers. We have investigated 2,050 workers through direct interviews during the period from April 12, 2010 to May 31, 2010. And the result of analysis, foreign worker's daily average working time is 10.6 hours(40.8% workers in total work 10~12 hours), the extent of exposure to harmful and dangerous working environment is 'the position which cause pain in neck, waist, hands, shoulders, legs'(69.3%), 'repetitive hands and arms movement'(66.1%). It showed 'experience of accident damage or disease related work'(27.3%), 'never apply for industrial accident compensation' is revealed high at 73%. As a result of completing a safety health education for a year, it showed 'never educated'(40.2%), 'the institute that foreign workers have used for help and advice is the foreign worker's support center'(61.9%) Thus, hiring foreign workers in the company are small in site, the environment is too harmful and dangerous. In addition, no safety and health managers, legally blind spot located in the health and safety, because it is an urgent meet for these measures to improve.

이동 컴퓨팅 환경이란 사용자가 어떤 장소로 이동하더라도 동일한 환경에서 네트워크 서비스를 지속적으로 끊임없이 제공받을 수 있는 환경을 말하며, Mobile IP는 이러한 환경이 가지는 특성들을 고려한 네트워크 표준 프로토콜이다. 하지만 이 프로토콜도 이동 노드의 빈번한 핸드오프 시 위치 등록 절차에서 반드시 흠 에이전트 (Home Agent, HA)를 접근해야 하므로 네트워크 자원과 서비스 지연을 초래하는 단점을 가진다. 따라서 본 논문에서는 지역적 외부 에이전트 (Foreign Agent, FA) 기법을 도입하여 방문 도메인에서의 등록을 지역화 하여 이동 노드의 빈번한 핸드오프 시 위치 등록 절차에 대한 지연 부하를 최소화 하는 방안을 제안한다. 또한 부하 분산 요소를 부가하여, 모든 FA가 상황에 따라 동적으로 루트 권한 FA가 될 수 있는 기법을 도입하여 중앙으로만 집중되는 위치 등록 메시지를 지역적 FA에 분산하여 네트워크 자원 낭비를 줄이고 빠른 위치 등록 응답 시간을 얻을 수 있으며 기존 Mobile IP에서의 패킷 지연 및 손실 그리고 재전송을 예방하고자 한다.

The Hong Kong's Anti-Ordinance Amendment Movement is the most serious radical social movement since the 1997 return, which has served as the promotion of the 2014 Occupy Central Movement and broken through the violence baseline. The movement came from a criminal case committed in Taiwan,which gave a good reason and motivation for the HK government to amend the Fugitive Offenders Ordinance. The HK government has responded to the protests by strictly limiting the legal scope and transfer procedure, even giving up the legislative motion. But the protests still say no and develop into the constantly violent activities. Many of the protests have committed the crimes in HK laws,part of whom have been arrested,prosecuted and under judicially judged. It is necessary for the offenders to be punished to protect the authority of rule of law in HK. Two different paths for HK have fought against each other since the 1997 return: one is the "democratic-welfare" path taken by the Pan-Democratic Camp, the other is the "Legal-development" path taken by the Pan-Establishment Camp. The second path shares some nuclear characteristics of the so-called The China Model mainly shaped from the 40-years Reforms and Openness. However, the HK people can't understand the China Model very well and show great fear and distrust on the judicial system of Mainland China. The foreign powers such as US and UK have illegally interfered the HK issues which are deemed to be the domestic affairs of China. The so-called Sino-UK Joint Declaration can't serve as the legal basis for the interference. Taiwan, as a part of China, also plays a negative role in this movement for its electoral and political interest. Up to now, the movement has gone down and the HK government has the legal capacity to solve the problems under the supports from the central government and the HK people. The HK people love its rule of law and order under the constitutional framework of One Country Two System. After the movement,One Country Two Systems will be go on, and the integrated development under the policies of the central government will be the main stream. However, the relevant problems exposed by this movement muse be checked and solved legally and strictly,especially concerning the social inequality and youth development.

The purpose of this study is to examine, specifically, the external and internal characteristics of anti-fashion expression in the Korean student movement after the 1945 Liberation. The dress expressed in the student movement represented the purity of student and characterized resistance, and this character expressed strongly in 80s, faded from middle of 90s. Until the 60s, the student movement was not characterized by, so activist students wore dress and suits. It symbolized students as an elite group of society. They added on head-bands to express resistance. In the 70s, activist students wore school uniforms, school military training wear, blue jeans and loose shirts in demonstrations. They tried to express re-bellion against the government and the older gen-eration. In the 80s, the period was remarkably distingusihing by the economic growth at that time. Activist students wore T-shirts with Korean letters and popular paintings specially made, Korean costumes, wrapped in the Taggeuki (Korean national flag), and refused wear on jeans because of anti-Americanism. They also wore masks, muffled their faces, and got their heads shaved. These anti-fashions are very strong expressions for the national independence spirit, national traditional heitage, anti-foreign power and anti-American. In the early 90s, activist students wore reformed Korean costumes specially made group uniforms, after that they wore casual everyday clothes with caps. They tried to express remarkable resistance in the early 90s, but after the mid-90s expression of resistance weakened and faded, so there was no distinction between activist and non-activist. There are the reasons why the student movement changed after the peaceful transfer of political power.
