  • The purpose of this study is to investigate the difference of grandchild care experience and psychological health between grandfathers and grandmothers, and the effects of grandchild care experience on the psychological health of them. The objects of this study were 371 grandparents who were living in Seoul and Gyeonggi provinces and caring for children aged 3~5. The results of this study were as follows: First, grandfathers performed more basic needs fulfilling, active parent, and educational role and felt more psychological well-being and generativity. Second, both grandfathers and grandmothers had higher generativity as they carried out more social emotional support and educational roles. For grandmother, the more the role of fulfilling the basic desire and social emotional support, the higher the psychological well-being. For grandfather, however, the four care roles did not affect the psychological well-being.

  • Gossi-cave, which is Natural monument No. 219, originally was called Norigok-cave, but happened Imjin-Japanese war, aborigine and Gossi family took refuse to Norigok-cave. Japanese soldiers set fire to this cave, in result lots of people had been died. And then, this cave was called Gossi-cave because Gossi family only survived during the war. Stalactite, Stone pillar that was created from four hundred million ago Harmonized with the others. The length is 6.3km in 1969.6.4. this cave was appointed natural monument as a result of investigating Korean Speleological Society. Kim SaKat a Master Poet(1807-1863) : A Genius with wit and eccentric conduct, a poet who wrote a refined poems with his own dramatic path of life destructed the format of Chines poem and created a new folk literature. He is Kim SaKat - a wizard of poet Kim Sakat - a poet wearing conical bamboo hat. Kim Sakat was born in 1807, in the latter part of Chosun period, his antonym was Kim Byung-Yun. He passed the state examination in the first place when he was 20. Two years later, he set out his life as a wanderer when he realized his winning composition was a criticism on his grandfather.

  • 상용 위성탑재카메라를 이용한 지표면의 고해상도 영상획득은 1990년대부터 세계 각국에서 많은 노력과 투자를 하고 있다. 미국은 이미 해상도 1m급의 IKONOS, Orbview 및 Quickbird 등을 운용하고 있으며 최근에는 해상도 0.5m급 이하의 위성탑재 카메라를 개발하고 있는 것으로 알려졌다. 러시아, 프랑스, 이스라엘, 일본 등도 1m급 탑재카메라를 개발 중이거나 운용중이며 우리나라도 다목적 실용위성 시리즈의 탑재카메라 개발을 통해 고해상도 위성 카메라를 운용 및 개발 중이다. 이러한 개발동향에 따라 고해상도 위성카메라의 광학부품과 구조부품에 대한 기술적 연구와 개발에도 많은 노력이 이루어지고 있는데, 국내에서도 향후 계속되는 국가의 위성탑재카메라 개발계획에 따라 요구되는 핵심 광구조 부품 개발을 위해 대구경 광학 부품이나 구조물에 대해서 단계적인 국내개발을 시작하고 있다. 우선적으로 한국항공우주연구원과 한국표준과학연구원은 연구원간 협력프로그램으로 대구경 우주급 반사경조립체에 대한 국내개발을 진행하고 있으며 우주환경에서의 광학시험에 필요한 관련 시설을 구축하고 있으므로 국내의 위성관련 광구조부품 개발 기술도 획기적으로 향상될 것으로 기대된다.
