영화불법다운로드 방지해법이 영화소비자의 소비행동에 미치는 영향

At this time when the illegal copying by Internet users is continuously active, Ministry of Culture, Sports and Tourism(MCST) reported that illegal works of overall online contents downloads reached 54.9 percent in 2008. It seems the increase in Internet speed and the supply of laptop are connected by the increase of consumers’ convenience, spreading more illegal movie downloads in the years ahead. The purpose of this study is to put forward specific measures against illegal downloads that illegal downloaders think, figure out how the Korean film industry is revitalized through them, and look for an solution that can use reasonably without shutting down the existing illegal download sites. The results are summarized as follows. Although an punishment-oriented legal solution could prevent illegal downloads strongly, crackdown-oriented prevention measures were not desirable in this situation that many of movie consumers implement illegal downloads and they don"t see it as illegality. A social solution, which will freshen up consumers’ perception through public relations and education of illegal download, should be preceded. Various prevention solutions, which can satisfy Korean movie consumers’ desires, not a standardized form, should be also put forward as alternatives.

본 논문에서는 우주개발 중장기 계획에 따라 2020년 이후 한국형발사체의 후속으로 계획된 정지궤도위성 발사체와 대형 위성 발사체의 개발 방향에 대한 논의와 이를 구현하기 위해 요구되는 발사체 기술들에 대해 전망한다. 차세대 발사체는 고성능화뿐 아니라 저비용 및 고신뢰도를 목표로 세계 위성 발사 서비스 시장에서 경쟁할 수 있는 발사체로 개발되어야 하며, 이를 위해 75톤 급 케로신/액체산소 로켓 엔진 등 한국형발사체를 통해 확보된 발사체 기술 기반 및 개발 성과를 활용하고 발전시키는 방향으로 개발되는 것이 바람직하다. In this paper the development directions of the next generation launch vehicle program following KSLV-II has been discussed, which are to be executed after year 2020 according to the Medium and Long Term Plan for National Space Development. Also, several areas of technology advancement have been identified for the successful development of the LVs. The next generation LV must aim for not only the high performance but also for low cost as well as high reliability in order to compete against global commercial launch service providers. To this end, the next generation LVs program shall capitalize on many anticipated accomplishments of the KSLV-II program such as the 75 ton class LOX/kerosene rocket engine.

일반적으로 소형 인공위성의 크기를 분류할 때에 마이크로위성은 그 무게가 10~100 kg, 나노위성은 1~10 kg 이내의 위성으로 구분된다. 나노위성은 대형위성의 제작비용과 발사 절감 노력에 따라 점점 더 관심을 받고 있다. 나노위성은 작고 제작비가 저렴하기 때문에 보다 작은 발사체로 궤도에 진입이 가능하고 상황에 따라 대형위성과 비교하여 즉각적인 대응이 가능하다는 장점이 있다. 또한 국내의 발달된 전자산업과 훌륭하게 갖추어진 IT 인프라를 감한하면 충분히 국제 경쟁력이 있는 주제이며 나로호, 한국형 발사체 개발을 통해 얻은 로켓기술을 활용하면 나노위성 발사시스템을 구축하는 것 역시 멀기만 한 일은 아닐 것으로 기대된다. In general, small satellites can be categorized into microsatellites and nanosatellites depending on the masses. The masses of the microsatellites and the nanosatellites are in range of 10 to 100 kg and 1 to 10 kg, respectively. These small stellites are getting more and more interest, as costs of manufacture and launch service for large satellites are getting higher. Since the nanosatellites are small and low cost, small rockets can put them into the orbits with reasonable cost. In addition, the nanosatellite can be launched relatively immediately compared with large satellites if necessary. In Korea, considered the advanced electronic technologies and IT infra, development of nanosatellite can be competed in the worldwide. Moreover, a nanosatellite launch system can be established not in far future from now if we use the technologies learned form KSLV and Korean Launch Vehicle Program.
