목표 주변의 부수피해를 줄이면서, 고도의 파괴력으로 적의 목표를 정확히 파괴할수 있는 신생기술무기는, 일반적으로 선제공격 억제효과의 측면에서 현재의 핵무기보다는 약하지만, 재래식 신생기술무기로도 적의 주요 목표에 대하여 전략적인 공격 성과를 달성할수 있으므로 전쟁 억제가 가능하게 될 것입니다 결국 신생기술무기의 출현은 세계적인 전면전의 가능성을 줄이게 될 것이며 핵전쟁으로의 확산을 방지하는데 커다란 영향을 주리라 생각됩니다

동양에서 금속활자인쇄가 가장 성행한 곳은 조선이다. 조선시대에는 정부 출판문서의 대부분이 금속활자였다. 금속활자는 주자라고도 하지만, 가장 많은 것은 동활자이며, 그 외에도 철활자.납활자.진유활자 등이 있었다. 또한 조선시대에 앞서 고려시대에 이미 금속활자인쇄는 행해지고 있었으며, 이것을 간략히 정리해 보면 다음과 같다.

원달러 강세는 과거 고도성장기에 수입가격 하락 및 물가 안정을 통해 내수 살리기 효과를 보여주었지만 내수부진에 시달리는 작금에 와서 원달러 강세는 우리 경제의 최대장애물로 등장하며 '마른 수건도 다시 짜야 한다'는 수준의 극단적 경영 불안감을 다시 환기시키고 있다. 환율변동과 국내 IT산업 그리고 기업들의 대응전략을 조명해본다.

웃음을 '만병통치약' 혹은 '신비한 명약'이라고들 한다. 실제로 전문가들은 1번 웃으면 5분 동안 에어로빅을 한 것과 맞먹고 1분 동안 박장대소하면 10분 동안 조깅한 것이나 진배없다고 한다. 또 면역력을 높여주는 물질이 200배나 활발히 분비돼 각종 질병을 예방해 준다고도 한다. 웃음이 우리 몸에 어떤 영향을 미치는지 알아보고 웃는데 도움이 되는 정보를 모아보았다.

Gyeong Po in Gangneung is highly recognized as a scenic area that is home to twelve traditional pavilions which are still in existence today. Since the modification of the Natural Park Act in 2007, there has been serious concern about the regulation of the heights of buildings surrounding Gyeong Po. In light of this, the present study aims to provide some guidelines for the regulation of building height in the modified Natural Park Act on the basis of investigations of landscape characteristics of Gyeong Po and the psychological influences of changing building heights. The analysis of the view from the pavilions located around Gyeong Po Lake indicated that the strategic landscape control points were Gyeong Po Dae and Bang Hae pavilions in terms of landscape management. These two landscape control points were considered as points from which people could view the greatest part of the landscape surrounding Gyeong Po Lake. The results of a preference analysis revealed that the views from Gyeong Po Dae to Juk Do were of relatively higher preference than the view from Bang Hae pavilion. This finding emphasized the importance of landscape management in Juk Do and its surroundings. A factor analysis resulted in three factors including attractiveness, tranquility, and orderliness. A comparison of the magnitude of influence of these three factors showed that the order of influence to preference was: attractiveness>tranquility>orderliness. These results highlight the need to introduce landmarks or unique buildings into the areas because the panoramic views of Gyeong Po Lake are relatively flat as lake views go. There should also be a variety of skylines harmonizing with the natural landscapes and landscape management for building groups, rather than individual building control, to enhance tranquility. Analysis of the psychological effects of building height suggests that, regardless of view points, preference was split at a 30 meter building height. This was indicative that viewer preference would drop when building heights are controlled to allow heights over 30 meters. The present study was not able to take varying view points and story heights into account. A more detailed study considering building types, the arrangement of buildings and the number of building stories is needed for effective landscape management in the Gyeong Po Dae area.

Various kinds of micro organic pollutants have frequently been detected from a water system. Therefore, it is considered to be very important part in the drinking water treatment system. And the research about removal process and processing efficiency have been being conducted briskly. In this study, the removal efficiency was evaluated using advanced water treatment process and nanofiltration process. The removal efficiency of nanofiltration process was very different according to physical and chemical characteristics of materials. The molecular weight of cutoff was the most influential factor in the removal efficiency. And when pKa value was higher than pH of raw water or Log Kow value was below 2, the removal efficiency of material was decreased. In case of oxidation reaction, the bigger the molecular weight of material was and the more hydrophobic a material was, the less oxidation reaction occurred. And the removal efficiency was decreased. Most unoxidized materials were removed by absorption. And the more actively oxidation reaction occurred by $H_2O_2$, the more absorption reaction increased.

There has been a strong demand for low altitude UAV development in rapid mapping not only to acquire high resolution image with much more low cost and weather independent, compared to satellite surveying or traditional aerial surveying, but also to meet many needs of the aerial photogrammetry. Especially, efficient geocoding of UAV imagery is the key issue. Contrary to high UAV potential for civilian applications, the technology development in photogrammetry for example direct georeferencing is in the early stage and it requires further research and additional technical development. In this study, two approaches are supposed for automatic geocoding of UAV still images by simple affine transformation and block adjustment of affine transformation using minimal ground control points and also evaluated the applicability and quality of geometric model compared to geocoded images generated by commercial S/W.
