This study investigates fitness of horizontal alinement design elements that has been used in Korea. Those elements are analyzed in consideration of road environment, drivers' characteristics, and traffic condition. In addition, reformed superelevation formula is produced to be fit to the conditions in Korea by considering horizontal alinement design elements on the base of 'AASHTO'. The results are summarized as follow 1. According to drivers' cognition analyzed by Factor analysis, drivers regard that road safety and horizontal alinement elements are the most important facts. 2. Superelevation value which is produced from radius of road curve in research area is shorter than standard superelevation value. Therefore, we should revise and supplement the standard superelevation in aspect of drivers' safety. 3. Superelevation value analyzed by 85 percentile running speed shows higher value than critical superelevation value used in Korea. So, we should upgrade the critical superelevation value.

Phytocystatins are protein inhibitors of cysteine proteinases of the papain family that have been identified in both monocot and dicot plants. A cDNA encoding a phytocystatin, BCPI-1 (Brassica Cysteine Proteinase Inhibitor-1) has been isolated from Chinese cabbage (Brassica campestris L. ssp. pekinensis) flower buds. Here, we tested whether BCPI-1 transcription is regulated by hormones, and could be involved in regulating cysteine proteinases during and after germination. BCPI-1 was sensitive to exogenous GA_(3) and ABA, which are important factors controlling seed germination, suggesting that the expression of BCPI-1 is hormonally regulated. We introduced a recombinant plasmid containing the full-length BCPI-1 cDNA under the control of cauliflower mosaic virus 35S promoter into rice embryogenic calli using the particle delivery method, and regenerated a number of transgenic rice plants. Constitutively over-expressed BCPI-1 caused changes in overall plant growth and development, including reduced germination and seedling growth. These data support the role of the BCPI-1 in the regulation of endogenous proteinases during both seed germination and subsequent seedling development. Phylocystatins은 papain계열의 cysteine 단백질 분해 효소 활성을 특이적으로 억제하는 억제자로 다양한 식물 종으로부터 분리되었다. 본고에서는, 배추 화아 cDNA library로부터 분리된 phytocystatin인 BCPI-1(Brassica Cysteine Proteinase Inhibitor-1)의 생체 내 기능에 대해 연구하였다. 먼저, BCPI-1 전사체는 발아 조절에 중요한 영향을 미치는 GA₃와 ABA에 의해 예민하게 증가, 혹은 감소되는 반응을 보임으로써, BCPI-1이 식물 호르몬의 영향을 받으며, 특히 발아나 유묘의 생장 조절에 관련이 있음을 알 수 있었다. Particle bombardment 방법을 통하여 BCPI-1을 벼의 배 형성 세포 내에 도입, 재분화 시켜 형질 전환 벼를 생성하였다. CaMV 35S promoter의 조절에 의해 지속적인 BCPI-1 발현을 보이는 형질 전환 벼의 경우, 발아와 유묘 생장이 현저히 지연되었다. 위의 결과들을 바탕으로, BCPI-1이 식물체 내에서 생성되는 cysteine 계열의 단밸질 분해 효소 활성을 조절하여 종자의 발아와 유묘의 생장에 영향을 미치는 것으로 추측한다.

북한 테러지원국 해제 이후 북핵 전망 및 우리의 대응방향

임채홍 원광대학교 2008 圓光軍事論壇 Vol.- No.4

NK's nuclear issue has double-faceted nature, e.g., an international or a regional issue related to nuclear proliferation and a domestic issue to pose security threat to the Korean peninsula. Recently, disablement process as regards the NK's nuclear facilities has resumed soon after the US State Department announced to remove NK from the list of state sponsors of terrorism. But considering a variety of future issues challenging SK & the US, it is merely a signal that the controversial long journey would begin before long. After terminating disablement, NK will try not to implement or to defer its further obligation if possible on the basis of typical salami tactics making use of forced insistence, unreasonable interpretation, blackmail, etc. It is since NK's nuclear program and its possession of nuclear weapons are useful vehicle of the last resort for its regime survival and sustainability. Reviewing the process of the six party talks, it could be said that there was not much solid ties and concerted cooperation among five parties except NK thanks to national security interests of individual country. In this context; SK should bear in mind following response measures in order to achieve NK's denuclearization successfully through the six party talks on the basis of the CVID(comprehensive, verifiable, irreversible dismantlement) principle. First, SK should continue to maintain six party talks having been lasted so far since 2003, and develop it to more substantive negotiations. Second, SK needs to highlight the role of China and Russia to create nuclear weapons-free NK. particularly through China's intensive pressure to NK. Third, SK ought to continue to attach importance to the CVID principle vis-a-vis NK's nuclear program and nuclear weapons involving the UEP(uranium enrichment program). Fifth, SK should strengthen ROK-US allied relations to stabilize possible military tension between the two Koreas, simultaneously cooperating with the next US government to place NK's nuke issue in the priority. Lastly, SK needs to prudently take into account the alternative plan to provide thermal power plants or whatsoever to NK in lieu of the LWR(Light Water Reactor) to block even the least feasibility able to produce plutonium. In conclusion, It would be essential for the five parties except NK to move forward to the same direction so as to establish denuclearized NK, taking advantage of aforementioned various strategic measures, and further to make NK be a responsible state of the international community, at the earliest date, complying with international nonproliferation norms, NPT and IAEA safeguards.
