The South Korean society has experienced many changes since the sinking of ROKS Cheonan. The government reviewed its defense posture and adopted the 5·24 Measure in its relations with North Korea. As a result, the people of South Korea became more conscious of security situations on the Korean peninsula while North Korea's economy suffered badly. Meanwhile, the South Korean government has taken a flexible stance toward North Korea in terms of exchange and cooperation since September 2011. The flexible stance was to manage inter-Korea relations in a stable manner and relieve the hardships of the North Korean people while preserving the spirits and purposes of the 5·24 Measure. The UN Security Council adopted twenty-six resolutions and statements on North Korea since June 25, 1950. They include thirteen U.N. Security Council resolutions including those concerning nuclear weapons or missile programs, nine Presidential statements, and four press statements. Resolution 82, the first U.N. resolution on North Korea, came when the Korean War broke out. Resolution 825, the first one related to nuclear or missile programs, was adopted in response to North Korea's withdrawal from the NPT. Apart from these U.N. resolutions, the United States has imposed separate sanctions against North Korea. North Korea's nuclear weapons program can be considered in comparison with that of Iran in terms of the consequences they create for the regional security. The Security Council has adopted six resolutions on Iran so far. One should note that the resolutions on Iran have had much stronger sanctions compared to those imposed on North Korea. That is, while the North Korea case may be viewed as a more serious threat to international security from the perspective of nuclear weapons development or proliferation, tougher sanctions have been placed on Iran. There are two approaches that South Korea should take in addressing the related issues. First, we should aim to reduce the gap between sanctions imposed on Iran and North Korea. It is difficult to understand that a country with more serious problems is rewarded with lighter sanctions. We should take measures through the Security Council Sanctions Committee to make individuals and groups in North Korea that play a central role in developing nuclear weapons and missiles subject to additional sanctions. Second, we have to change. Other countries in the international community have become tired of North Korea's nuclear issue and now they look to South Korea for initiative. We should correctly understand this current situation and play a leading role within our capacity. Knowingly and unknowingly, the notion that the North Korean nuclear issue may be left to South Korea has been spread around the international community. Although the situation is grave, we should try to open a new horizon in ushering in the unification era by taking the initiative with confidence that there is a looming hope ahead of us. For these tasks, we should stop thinking in the old way that has been ossified for the last two decades. We should not be pushed around by neighboring great powers in dealing with North Korea related issues anymore; we should take the initiative with resolution that we will play our role at the center of four great powers and with confidence that we can do it. Based on the confidence that the Republic of Korea has become a country with enough capacity to take the initiative, we should establish a 'National Grand Strategy' representing South Korea's strategic vision that the unification is the ultimate solution to the problems related to North Korea's nuclear weapons program.

Construction managers who are placed on the top of the construction production organization should exhibit its best knowledges concerning all aspects and control related members at every position properly. In case of CM firms in developed countries, they are equipped with a practical system of technology and management knowledge, and efficiently use the knowledge not only for novices but also experts. However, the domestic CM firms which are now at the lower level than those in developed country are not supported with the sufficient and systematic knowledge for CM tasks due to various reasons. Therefore, the objective of this study is to suggest the direction and strategy for the development of an experts-knowledge management system to enhance the construction productivity at the viewpoint of CM firms which conduct, manage and supervise various tasks of construction projects. Domestic CM firms would play a great role to enhance productivity and secure competitive advantage of project management as much as the firms in developed countries if experts-knowledge and information are supported by a computerized system.

Most of the known RFID applications are derived from RFID technology and its functionalities not business analysis or requirements, so that companies may not obtain real competitive edges by implementing RFID application systems. Developing successful RFID applications is one of the key elements for prevailing RFID use by industries. Research objective is to propose an effective methodology for developing RFID applications based on analyzing business processes. The approach is designed to figure out both technical and business requirements related to RFID applications based on BPR (Business process reengineering) and ISP (Information strategy planning) methodologies. To verify the effectiveness of our approach, we applied the proposed approach to real field cases. As RFID technologies get flourished, the proposed approach is expected to play a meaningful role as an effective tool for developing new RFID applications.

The degree to which parallel evolution utilizes the same genetic mechanisms indicates the degree to which developmental processes constrain or channel phenotypic evolution. A transgenetic strategy was used to elucidate the role of one floral meristem identity gene, LEAFY (LFY), in the evolution of rosette flowering, a plant architecture that has evolved in parallel in several lineages of the mustard family, Brassicaceae. The LFY genes from three rosette flowering species were cloned and introduced into a species with the ancestral architecture, and results indicated that changes at the LFY locus contributed to the evolution of rosette flowering in two of the three lineages, but that in each lineage a different set of genetic partners was involved. Also, LFY was shown to play a role in the evolution of flower size. Transgenetic strategy may be useful in the study of plant morphological evolution and parallelism.

Lung-resident memory T cells (T_RM) play an essential role in protecting against pulmonary virus infection. Parenteral administration of DNA vaccine is generally not sufficient to induce lung CD8 T_RM cells. This study investigates whether intramuscularly administered DNA vaccine expressing the nucleoprotein (NP) induces lung T_RM cells and protects against the influenza B virus. The results show that DNA vaccination poorly generates lung T_RM cells and massive secondary effector CD8 T cells entering the lungs after challenge infection do not offer sufficient protection. Nonetheless, intranasal administration of non-replicating adenovirus vector expressing no Ag following priming DNA vaccination deploys NP-specific CD8 T_RM cells in the lungs, which subsequently offers complete protection. This novel 'prime and deploy' strategy could be a promising regimen for a universal influenza vaccine targeting the conserved NP Ag.
