종이의 기계적, 물리적, 광학적, 강도적 특성을 발휘하는 메카니즘을 이해하기 위하여 섬유특성과 침엽수, 활엽수 펄프 혼합비에 따른 종이의 특성, 파괴인성을 분석하였다. 침엽수, 활엽수 펄프섬유를 각각 450 ml C.S.F.로 고해한 후 초지하여 특성을 측정하였다. 침엽수 펄프섬유는 고해에 의하여 섬유간 결합이 효율적으로 향상되어 섬유네트워크가 형성되어, 강도가 상승하고, 비산란계수와 불투명도가 낮아졌다. 파괴시험 결과 침엽수 펄프섬유는 향상된 섬유간 결합에 의하여 섬유의 파괴가 섬유의 뽑힘보다 많이 일어났으며, 활엽수 펄프섬유는 섬유의 뽑힘이 섬유의 파괴보다 많이 일어났다. 혼합초지시 SW 80 : HW20에서 섬유 간 결합의 향상과 응력 집중을 효율적으로 분산한 결과 최대의 파괴인성을 나타내었다.

The collapse of Socialism and economic crisis of the North Korean regime in the 1990s increased the number of North Korean defectors rapidly. As of now, the number entering South Korea is over 10,000 and the people staying in foreign countries are estimated to be hundreds of thousands. This study examined the reasons of defection first, and then observed the conditions of defectors' human rights and policies of related countries such as China and Russia. Further, the author reviewed whether South Korea can claim the diplomatic protection rights for the defectors. Finally, their status as refugees under the international treaty was examined and several protection schemes were suggested. While economic crisis is the most important reason of defection, other reasons also contribute to the reason, such as contact of foreign information, social instability, change of traditional value, and malfunction of social control. Since the North Korean defectors staying in foreign countries such as China have to live as illegal immigrants, they do not have stable habitats and suffer from a variety of human rights violations such as forced marriage, human trafficking, and labor extortion. The issues of nationality and refugee status must be solved to protect the legal status of the North Korean defectors. The South Korean government has to clarify the definition of a citizen in its nationality law, and strengthen the cooperation with human rights organizations of UN and NGO. Also, it must inform international communities of the human rights status of the defectors, helping them acquire the refugee status and keeping them from being repatriated to North Korea. Mutual responses with related countries are also important. Such efforts need to be exerted to contract the “regional refugee treaty” involving China, Russia, Vietnam, and Mongolia. Also, it would be another approach to found a regional level security committee and construct a facility for refugee protection. The North Korean defectors are living a tough life with little support for human rights. Regardless of the malfunction of the North Korean regime, the passive approach of the South Korean government must be put on the table. Our government has to grasp the current status of the North Korean defectors and prepare related laws. By doing that and taking other measures, we must make a new approach to absorb the defectors into our citizens for the preparation of reunion.
