It has been an always issue for the blasting or the impact analysis to consider the strength characteristics of the rock materials associate with loading rate dependency. Due to the nature of transient loading, the dynamic rock test requires a careful technique to achieve the stress equilibrium state of the specimen. In this study, to investigate the relationship between the rock dynamic strength and the stress equilibrium state, a series of dynamic uniaxial compression tests for Pocheon granite were performed. As a result, the unbalanced stress state on the specimen can lead to the premature failure on the specimen and the less estimation of dynamic strength characteristic as well as the overestimation of strain rate. Consequently, a careful consideration of rock fracture process to achieve the dynamic force balance on the specimen should be required to make an reasonable evaluation of rock dynamic strength.

In the era of digital transformation, new technologies have begun to be applied in the field of records management, away from the traditional view that emphasized the existing institutional and administrative aspects. Therefore, this study analyzed the service status of archives, libraries, and museums applied with advanced intelligent technology and identified the differences. Then, we proposed how to apply intelligent archival information services based on the analysis results. The reason for including libraries and museums in the research is that they are covered by a single category as an information service provider. To achieve our study aims, we conducted literature and case studies. Based on the results of the case study, we proposed the application strategies of intelligent archival information services. The results of this study are expected to help develop intelligent archival service models that are suitable for the changed electronic records environment.

Recently, various methods of collecting and preserving social media have been discussed in the field of archives and records management as social media is actively used as a way of communicating with the public in the government. In the United States, there is a move to acquire and preserve social media at the government level, and the National Archives (UK) already provides social media archives to users through Twitter and YouTube. In this study, we proposed the features, acquisition methods of social media by type and the preservation model based on case study results in terms of acquisition and preservation of social media archiving. In order to verify the effectiveness of the proposed methods, this study was applied to the social media of Gyeongsangnamdo provincial government. The results of this study is meaningful in that it suggested acquisition and preservation methods through actual collected results and it is expected that it will be useful for establishing the models for future social media archiving.

The purpose of this study was to improve the unstable treatment posture by placing the Carbon fabric blanket on the couch which was used for the patient fixation for the unstable posture from the severe pain caused by the neuromuscular pressure of the spinal metastatic cancer patient and to analyze the dose difference caused by the energy loss of high energy radiation. Using a linear accelerator, a FC-65G was installed at a depth of 5 cm at a solid phantom at 6 MV and 10 MV energies. The SAD was 100 cm, Gantry angle was $0^{\circ}$, a Cotton and Carbon blanket with a thickness of 1 cm on the couch, The blankets were placed on the couch and the dose was measured according to field size. For the dose measurement, and the dose was measured at 100 MU each time, and the mean value was calculated by repeating the measurement three times in order to reduce the error. The results showed that the difference rate in dose between Carbon blanket and Cotton blanket was respectively -0.54% and -0.75% based on the absence of the blanket(Non). Therefore, it is considered that the use of Carbon fabric blanket, which reduces the patient's pain and does not affect the depth dose, may be useful during radiation therapy of the spine metastasis cancer.

This study investigated the feasibility of $CaSnO_3$ particles as an oxygen carrier in chemical looping combustion (CLC). $CaSnO_3$ particles had a perovskite crystal structure and showed the structural stability after repeated reduction-oxidation reactions. The oxygen transfer capacity was 15.4 wt% almost the same as the calculated theoretical value from the crystal structure transformation during reduction. After $10^{th}$ cycles of reduction and oxidation, the oxygen transfer capacity and rate were still maintained constantly at an operating temperature. In conclusion, $CaSnO_3$ particles could be a good alternative material as an oxygen carrier in CLC.

In order to effectively respond to repeated disasters, the most important thing is the systematic management of records which were produced from past disaster response processes. It is necessary to develope a business reference model(BRM) to incorporate scattered disaster safety record information resources into the record management system. In this regard, this study examined crisis management standard operation procedures(SOP) manuals and analyzed common businesses of disaster and safety response processes. Based on analysis of 28 manuals three times, 1,667 main business transactions are drawn, which are grouped by 5 middle functions and 20 small functions. Furthermore, by looking at forecast records by business type, several insight is proposed in terms of disaster and safety response business processes and of disaster and safety records management.

The archival contents of the National Archives of Korea are organized so that anyone can easily use the records with a lot of social interest or request for reading. However, there are some problems in accessibility of archival contents, lack of detailed information, difficult to use and less interesting delivery method, and lack of customized content. As an alternative to this, this study proposed the utilization method of the archival contents of the National Archives through YouTube channel. For this purpose, we analyze the status and problems of the archival contents of the National Archives and understand the contents of the YouTube channel of the foreign agencies and the National Archives, and evaluate and compare them. Based on this, we propose and apply the process of the archival contents visualization using YouTube. Through this, We expect that the recognition and usability of the contents information of the National Archives of Records will be improved.

Archives of Government-Affiliated Organizations have responsibility for collecting and preserving valuable records produced during the business processes of their work and for actively serving users at the same time. This study applied Quality Function Deployment(QFD) techniques to analyzing user's actual requirements and proposing improvements for the archives service quality of central government agencies. In order to derive the components of the QFD, a survey was conducted among internal users of records centers in six central government agencies, as well as a literature study and interviews with working-level records researcher were also conducted. Afterwards, The House of Quality(HoQ) was constructed based on the user's requirements and technical characteristics derived, and the importance and priority of the recorder service technical characteristics were derived based on it. Based on the results, archives service of central government agencies should focus on improving the usability of records for internal user. Especially, it was confirm that the support for searching, reading and borrowing services should be strengthened.
