As APT attacks become more frequent and sophisticated, not only the advancement of the security systems but also the competence of the cybersecurity officers of each institution that operates them is becoming increasingly important. In a large-scale cyber defence exercise with many blue teams participating and many systems to simulate and defend against, it should be possible to simulate attacks to generate various attack patterns, network payloads, and system events. However, if one RT framework is used, there is a limitation that it can be easily detected by the blue team. In the case of operating multiple RT frameworks, a lot of time and effort by experts for exercise setup and operation for each framework is required. In this paper, we propose iRF(integrated RT framework) that can automatically operate large-scale cyber defence exercise by integrating a number of open RT frameworks and RT frameworks created by ourselves.

In the early 1990's, international security environment bring on the change. So each countries should have renewed the defence policy. The developed countries make efforts to keep the superiority of military industry with an high technology and huge capital. One of the efforts is the defence industry exhibitions for the management performance regarded as the marketing strategic principal method. The result of the opening exhibitions has been studied by research papers and treatises. A exhibitions' goal is different from an it's characteristic, type, industry, participator, institution and participating nation. An enterprise's management performance is runs as follows. First, an exhibitions participation activation has an effect re-participation following the satisfaction. Second, an exhibitions participation activation contributes to be on sale promotion, The result of the exhibitions participation is classified with sale performance and non-sale performance. The third, an exhibitions participation activation contributes to the effective company management. The huge fund advertisement is a financial burden, but a exhibitions takes effect one-fifth economical retrenchment. Accordingly, this study researched the exhibition participation choice properties, an exhibitions participation activation properties and investigated the Korea defence industry's income statement, balance sheet, growth ratios, profitability ratios, productivity ratios, stability ratios which were substitute for the enterprise's management performance through the exhibitions participation costs and the number of times.

Two erosive burning models were applied to compare analysis results of ballistic for the internal ballistics of solid rocket motors. By comparing motor tests with results of analysis, the variance of a grain shape was analyzed and coefficients of erosive burning were drawn. Results of comparison presents that the coefficient of erosive burning was proportional to the change of burning area, while inversely proportional to the change of cross area.

The STS materials, emphasized in the 6th curriculum, in the chemistry part of middle school science textbooks were analyzed. The average value of the STS content of textbook was 13.2%. In the study of chapter of textbook, 15.9% of STS materials was included in the chapter of ？reaction of materials?, 12% in "character and separation of materials", and 10.8% in "composition of materials". When the STS topics classified by Piel were analyzed, the results were as follows; 40.2% on sociology of science, 28.8% on environmental quality and utilization of natural source, 20.4% on effects of technological developments, and 12.9% on energy. However, the topic on human engineering was only included in a textbook, and the topics on space research and national defence were not included in any textbooks. When the STS materials were analyzed by student activities of SATIS, the number of activities was 71. Most activities were consisted of solving problems and decision, simulation and data analysis, and there was no research design and role playing.

This study is focused on the service quality and customer satisfaction. The survey on the service quality and customer satisfaction has the follows; First, man group compared to female group provision was receiving the service of good quality and also the customer satisfactory degree appeared highly. Also, the quality of the group one recording service where the age is many appeared customer satisfactory boat song highly. Second, the customer satisfaction regarding a high educational background one recording service quality did not appear highly and not to be with the thing recording where the educational background will be high provision to receive a more many serviceit is satisfied it appeared. It follows, consequently in member of society nine statistics quality and service quality of civil expense and the customer satisfaction is a difference and the recording customer where the service quality of civil expense will be high it goes round satisfactorily and there is possibility of saying that. Third, in service quality empathy characteristic of subordinate result, with the fact that static effect it will be going mad to a shedding of corporeal service satisfaction and a security facility satisfaction. The security facility satisfaction where the empathy characteristic and shedding of corporeal service quality will be good is high reflects a fact and it is giving. Fourth, market segment anger strategy and there is a necessity which will form the customer layer which is various. Also, the site for the service of good quality the operation of development and strategy elder brother system of the elder brother system which it fixes is necessary.

The Northern Song Dynasty Period (北宋時代) was a drastic transitional era in all aspect of Chinese society including the politico-economic system, ideology and cultural trait. These changes that began in the late Tang (唐) Dynasty Period accomplished in the Northern Song Dynasty. In this phase, the fundamental change influenced in all institutional area; and among them, the capital city planning and its associating building technology to pile stone walls shows one of the significant change of those time. Based on the geographical factor, confluences of many rivers, the Kaifeing (開封) area where the BianLieng palace had developed as a political and economical centre since the Tang Dynasty when the Grand Canal was constructed. According to archaeological researches, the central city structure of Dongjing Walled Town was begun to plan in the late Tang Dynasty and formed in Five Dynasties. The fundamental functional change of city completed in the Midnorthern Song Dynasty. In spite of the relatively late beginning of archaeological investigations to Kaifeng Walled Town and Dongjing Walled Town due to unfavourable natural environment, excavations inaugurated since 1981 have achieved the significant investigations including the actual measurement and excavation to the outer wall, the preliminary excavation to the inner city area, the investigation and excavation to the royal palace of Song and the survey to the royal palace of King Zho in the Ming (明) Dynasty. These surveys have provide important data to reconstruct the 변량 palace, and elucidate the characteristics of city plan in the Dongjing Walled Town and the institutional change of capital city plan of the Northern Song Dynasty. The basic layout of Dongjing Walled Town reflect the realisation of ideality of the late Chinese medieval capital city structure that establish the commercial and economic centre based on the intensification of emperor's power by means of the organisation of ethical institution and the development of commercial economy. Firstly, the central place of the Kaifeng area is encircled with triple walls. This emphasise the authority of emperor located on the summit in the hierarchical ethic system succeeding to the main capital city plan of the late phase of ancient China. Secondly, the location of Dongjing Walled Town was decided by the transport network and the commercial function and defence function. Thirdly, this site shows the change of city structure and landscape of the Northern Song Dynasty. The closed Fengri (坊里: block) system transferred the open Jiexiang (街巷: road) system. Fourthly, the capital city was characterised by the free market trade and the diversification of market place.
