Purpose: The purpose of this study is to prepare a more efficient operation alternative for both systems by comparing and analyzing the recently introduced COOP(Continutiry of Operation Plan) and existing NIPP(National Infrastructure Protection Plan). Method: The basic data of the two systems were collected for research and compared and analyzed by dividing them into the content and procedural aspects. In addition, The efficient operation alternative were derived for experts in the disaster area by utilizing AHP. Result: The National Infrastructure Protection Plan(NIPP) and the Continuity of Operation Plan(COOP) were found to be very similar in terms of content and procedures, and the AHP survey also found that integrating the two schemes was a more efficient and effective operation method. Conclusion: As the recently introduced the Continuity of Operation Plan(COOP) has a wider area of activity than the National Infrastructure Protection Plan(NIPP), and has a continuous management system structure with a more precise workframe, A more efficient national safety net will be realized by reorganizing and integrating it into a more enhanced the Continuity of Operation Plan(COOP) through readjustment of relevant laws and regulations.

This paper suggests a realistic, business engineers' model based on Coop projects run by regional universities or colleges, in which students must meet the guidelines for engineering design that ABEEK requires. Many of current activities such as Coop programs and Internships aimed for engineering majored-undergraduates have notled them either to a satisfactory level of business skill at entrepreneur side, or to their higher chance of employment opportunities. Under the circumstances like this, we need a revised version of Coop activities: for example, launching a project that will be fully supported intrust by both sides, and thus improving students' business skill while they are working on that project. We demonstrate in this study how students have greatly improved their business skill through a model project that was planned by a working group, was successfully carried out on real job positions, and many of the students in the working group were job-offered finally as this new model suggested.

Unexpected massive disasters have occurred around the world, causing enormous socio-economic damage. The military has long been enacting laws, organizing organizations and establishing systems for crisis and disaster management, but it did not consider the situation when military essential functions were suspended due to unpredictable and massive disasters. With the September 11 terrorist attacks, the U.S. military has developed COOP strategy aimed at continuing military essential functions in all crisis, and is contributed to national continuity by ensuring uninterrupted national security functions. Korean military has established a crisis and disaster management system, but focuses on managing and controlling disasters and crisis situations. Korean military needs a system to guarantee military essential functions even in national crisis beyond its management capabilities. In this study, We compared and reviewed the U.S. administration and military COOP guidelines and directives, ISO22301 international standards., and developed planning guidelines suitable for the Korean military situation by responding to detailed items based on ISO22301. In particular, the U.S. military(DoD, Army, Navy, Air Force) COOP guidelines were drawn and incorporated into the guidelines(such as protection and succession of command authority, the fulfillment of essential functions and operational security, etc.). The planning guidelines are expected to be used as reference materials for the introduction of COOP systems in the military and the establishment of plans in the future.

Globally, various disasters such as typhoons, floods, earthquakes, fires, explosions have caused work to be halted. If there is a large-scale disaster at public institutions in charge of major national affairs and their works are interrupted, not only will there be property damage, but there will also lead to a decline in national credibility and direct and indirect impacts on the people. Therefore, it is necessary to ensure continuity of operation by minimizing the interruption period of critical operations due to disasters. Overseas advanced countries such as the United States and Japan developed guidelines for Continuity of Operation (COOP) to prevent unexpected work disruptions caused by disasters. Recognizing the necessity of COOP in South Korea, a relevant law has been newly established in 「the Framework Act on the Management of Disasters and Safety」 to enable public institutions to establish the COOP in response to this situation. In this study, the definition, the necessity and overseas cases of COOP were investigated and described. Using the templates developed by these results, operational impact analysis, risk assessment, operational continuity strategies and operational continuity procedures were applied to "A" City Hall in Gyeonggi-do province and those results were described. The objective of this study is to substantially contribute to the introduction of COOP to local governments through their pilot application and implications of COOP.

This paper aims to describe how knowledge management could be put into practice in a voluntary way. From a practice-based standpoint, this study focused closely on the linkage between knowledge and practice. It is because knowledge management could fail if not put into practice. Using its own information system, iCOOP, a federation of consumers' co-operatives in Korea has been practised successful knowledge management voluntarily with its members. Based on the exploratory case study on iCOOP, this study conducted focused interviews with 5 member co-operatives of iCOOP. Main findings are as follows. First, an NoP emerges within a corporate information system when corporate work processes are concentrated in the information system. Second, corporate information system facilitates CoPs and the NoP when its information and information about its users are opened to all of the information system users. In conclusion, this study points out that it is not the matter of primary importance to build a knowledge management system. Rather, practice has the key to the successful knowledge management.

Interference between primary user (PU) and secondary user (SU) transceivers should be mitigated in order to implement underlay spectrum sharing in cognitive radio networks (CRN). Considering this scenario, an improved joint subcarrier and bit allocation scheme for cognitive user with primary users' cooperation (PU Coop) in CRN is proposed. In this scheme, the optimization problem is formulated to minimize the average interference power level at the PU receiver via PU Coop, which guarantees a higher primary signal to interference plus noise ratio (SINR) while maintaining the secondary user total rate constraint. The joint optimal scheme is separated into subcarrier allocation and bit assignment in each subcarrier via arith-metric geo-metric (AM-GM) inequality with asymptotical optimization solution. Moreover, the joint subcarrier and bit optimization scheme, which is evaluated by the available SU subcarriers and the allocated bits, is analyzed in the proposed PU Coop model. The performance of cognitive spectral efficiency and the average interference power level are investigated. Numerical analysis indicates that the SU's spectral efficiency increases significantly compared with the PU non-cooperation scenario. Moreover, the interference power level decreases dramatically for the proposed scheme compared with the traditional Hughes-Hartogs bit allocation scheme.

A purpose of this study is to comprehend a concept of 'Open Space', realization of a deconstruction, presented in his works, based on a deconstruction and surrealism Coop Himmelblau's philosophical contemplation and to look into how this concept is interpreted in spaces. A concept of 'Open Space' is functioned as not a singular meaning but a multiple meaning accompanied with other formative ingredient and contemplation, scientific paradigm and a realation with a surroundings. The concept of 'Open Space' in their architentural space is applied. First, the space openness that represents to the extreme a concept 'Open Space', as a 3D designing ways that demolishes a structure and outgrows an ex siting thinking pattern, represents multiple grade spaces and an anti-gravity space. In a material, using glass and iron provides a spacial transparency and through this, visibly liberal sense that an interior and exterior is felt as an unification. Second, an non-expressive box pattern repulses to a spatial rank nature, outgrowing an uniform geometrical system, through demolishing a geometrical system, an edge and fold pattern. This is, as an anti-gravity, dynamic a typical structure, outgrowing an orthogonal system, interpreted as a composite meaning without division in spatial area. Third, the collage is used to represent a complexity and pluralism in representing 'Open space'. The collage that forms a image through combining a fragmentary elements into being a space change, composite constitution and spatial amusement. Thus, It is worthwhile to study how the collage that forms a diverse shape will be developed making what impact as an age and surroundings changed. As we contemplate in former part, Coop Himmelblou has deployed 'deconstruction beyond deconstruction' realm as just their midterm concept in their works like the words 'The architecture must climb', the deconstructive architect. A studying for their works reflecting the 'Open Space' concept based on deconstruction must be lasted and this enables us to comprehend space concept containing an architecture and interior design.

Objective: This retrospective study was performed to evaluate the role of chemotherapy in the management of patients with anaplastic astrocytoma (AA). Methods: We compared the survival outcome among the 3 different treatment protocol groups in a single institution. A total of 86 patients (39 men and 47 women) with newly diagnosed AA after surgery were analyzed. Among them, 31 patients (36.0%) were treated with radiotherapy only (RT Group), 30 patients (34.9%) were treated with nimustine-cisplatin chemotherapy before RT (ACNU-COOP group), and 25 patients (29.1 %) were treated with procarbazine, lomustine and vincristine (PCV) chemotherapy after radiotherapy (PCV group). Results: The median survival was 14.0, 30.0 and 72.0 months in RT, ACNU-COOP, and PCV group, respectively and showed significant differences (RT vs. ACNU-COOP; p=0.039, RT vs. PCV; 0.002, ACNU-COOP vs. PCV; 0.045). PCV group showed less toxicity rate (5 patients; 20%) than ACNU-COOP group (12 patients; 40%), while only 3 patients (9.6%) in RT group experienced grade 3 or 4 toxicities. Conclusion: An application of chemotherapy before or after radiotherapy is beneficial in prolonging the survival of patients with AA. Adjuvant PCV chemotherapy after radiotherapy is recommendable.
