A preliminary study for energy efficient soil heating and contaminant removal using microwave was conducted. Soils sampled from floodplain were heated with microwave oven, and soil heating property and energy efficiency were compared to those heated with electrical furnace. In addition the effects of water, soil organic matter, and contaminated diesel on soil heating with microwave were investigated. Even though the electrical power consumption of electrical furnace and microwave oven were similar, temperature of soil heated with microwave oven was significantly higher than that of soil heated with electrical furnace. The increase of soil moisture content delays the raise of soil temperature during heating it with microwave oven. However, the effects of total petroleum hydrocarbon (TPH) (<10%) in contaminated soil matrix and small amount of soil organic matter (<5%) on the increase of soil temperature by microwave were not significant. Further studies for contaminated soils with different texture using pilot scale microwave reactor are required for application of this technique in the field.

Recently, a number of military intranet infiltrations suspected of North Korea have been discovered. There was a problem that a vulnerability could occur due to the modification of user authentication data that can access existing military information systems. In this paper, we applied mutual verification technique and API (Application Programming Interface) forgery / forgery blocking and obfuscation to solve the authentication weakness in web browsers that comply with FIDO (Fast IDentity Online) standard. In addition, user convenience is improved by implementing No-Plugin that does not require separate program installation. Performance tests show that most browsers perform about 0.1ms based on the RSA key generation rate. In addition, it proved that it can be used for commercialization by showing performance of less than 0.1 second even in the digital signature verification speed of the server. The service is expected to be useful for improving military information system security as an alternative to browser authentication by building a web secure storage.

In the Republic From the national interest in the recent hiring scandals in the public institutions such as the Financial Supervisory Service, Gangwon Land, and so on, people were outraged by the fact that the competition opportunities were not secured although they should be equally secured to compete with anyone with their capabilities in the fair process. Hence, the government made the public institutions blind hiring to be mandatory, which eliminated writing the academic background, GPA, and English score in the application form and selected the new employees only with job competencies in the public institutions in 2017. In 2018, the prosecution did their best for the investigation on hiring scandal with the strong will to cut the scandal upon announcement of 5-year anti-corruption master plan. Amid this controversy, this study tries to suggest the further direction in the hiring military human resources upon introduction of blind hiring system, reviewing the needs to introduce blind hiring system in the military, the governmental guideline according to the mandatory blind hiring in the public institutions, and the application status of modified blind hiring in the military.

The very fact that so many of us are here to participate in this conference on Operations Research is an indicator of the importance we attach to this relatively new and still expanding field. All of us recognize that Operations Research techniques are especially useful tools in problem solving in business, Government and the military. A discussion of the role of Operations Research and the related field of Systems Analysis in national defense policy and programming decision processes seems especially appropriate at the opening session of this conference, As you know, Operations Research as an organized form of research first found application in the review of individual military weapons systems and their effectiveness just over forty years ago. From that relatively narrow beginning has evolved a discipline whose future exploitation and utility you will explore over the next several days. I plan to review very briefly the historical development of Operations Research and Systems Analysis as tools in the defense decision-making process. Then, I will give you an overview of their application to today's military and defense problem solving by discussing the use of these techniques at the headquarters level by the United States Navy, Obviously, in such a brief period, I cannot cover all applications, specific techniques, or all of the groups involved in such a complex process. A review of the historical development of Operations Research/Systems Analysts reveals that the use of the basic concepts of Operations Research is not new; it originated with the first attempts to use the scientific approach to solve problems. We are still seeking, through modern analysis, to answer the three questions posed by John Dewey in his examination of the problem solving process in 1910.'1 - What is the problem? - What are the alternatives? - Which alternative is best? As I noted earlier, Operations Research, as an organized form of research, began in Great Britain in the late 1930s with the review of individual weapons systems.

Shuangdan oral liquid (SDO) containing radix Salviae miltiorrhizae (Chinese name Danshen) and cortex moutan (Chinese name Mudanpi) is a traditional Chinese medicine using for treating vascular diseases. Danshensu (DSS) is a main effective monomer composition derived from radix Salviae miltiorrhizae and paeonol (Pae) from cortex moutan. Although the two herbs are widely used in traditional Chinese medicine, the pharmacological functions of their active compositions were not reported. Therefore, the research of DSS and Pae in mechanisms and pharmacodynamics interaction can provide scientific evidence to support clinical application. The diabetic nephropathy (DN) rats which were induced by streptozotocin (STZ) were treated with SDO, DSS, Pae, and DSS+Pae for eight weeks. The positive effects on DN animal models were investigated by detection of physiological and biochemical indexes and oxidative stress markers, within five treatments: SDO, DSS, Pae, DSS+Pae and insulin group. Compared with the model group, the DSS+Pae group improved the renal function, blood lipid metabolism and blood viscosity, increased the vitality of T-SOD or T-AOC and decreased the level of MDA or NO after the treatment. The study was successfully showed that the DSS+Pae group could delay the process of DN, especially in the renal injury part of histopathology changes. Our results suggest that the co-administration of DSS and Pae significantly may play a protective role in DN rats through decreasing the oxidative stress and improving the blood lipid metabolism mechanisms.

This study carried out a covariance-structural analysis to verify formed causations between general variables and the influences of Medical Social Work Service of officers and NCOs in Korean Community Military Hospitals. The subjects were 7 hospitals, 337 military hospital executives in rear area, and the results of the survey are as below. First, about empowerment level, culture in the organization turned out to be the primary direct influential factor, and personal, organizational, and functional character were influential factor. There was no indirect influential factor present. Second, in Medical Social Work Service, empowerment level was significant on direct effect. In case of personal character indirect effect was important. It showed that the significant influence factor that affects Medical Social Work Service in total effectiveness is personal character and empowerment level. It's productive to suggest the possibility of application of furnish the outcome as a basic data for Military Medical Social Work Service revitalization plan. On the basis of the result, we propose several suggestions for Military Medical Social Work Service as follow. First, to educate empowerment increase program of officers and NCOs in Military Hospital, specific system which allows entrust education to a certain civil education institution or KAMTSW(Korean Academy of Military Social Welfare) is required. Second, need to provide the medical social work service that matches with Military Hospital and distinct from usual hospital. Last, for specific study we expect various follow-up researches on the basis of this study, which can develop concrete empowerment model by inquiring research, would come out.

Multi-resolution modeling(MRM) is required when simulating objects in variable resolution and can be applied for interoperating systems, which simulate objects in fixed resolution. However, most interoperation middleware do not support MRM, so participating models must handle several issues to simulate MRM system. In this paper, we propose an interoperation system, which is composed of several different resolution models, based on the High Level Architecture and Run-Time Infrastructure(HLA/RTI). In the proposed architecture, each model participates to a HLA federation through MRM adapter application, which supports data resolution conversion and HLA services while communicating with the model. MRM adapter application can be implemented based on an MRM adapter, and an adapter application development tool is proposed to support developing the application. Using the tool, developers can easily implement data resolution conversion component plugged-in HLA adapter. A case study is implemented in the proposed MRM system, and shows that models of different resolution works successfully with dynamic resolution changes.

Military Geography is a literature studying the application of geographical elements to military behaviour. The elements of military geography including topography greatly influences on building military art and theory. The military art applied on korean pennisula from the period of ancient three countries(Koguryeo, Shilla, Paekche) has been developed maintaining consistent stream reflecting topographic features. Despite the close relationship between building of military art and military geography's elements, the study for korean military geography has been depressed and the discourses of literature has been insufficient. But, in the western study of military geography, the study vitalization efforts studying military peace keeping and humanitarism activity are ongoing. Based on the current trend of western study and the analysis of existing korean study, this treatise proposes three plans to improve the study and education of korean military geography. The key contents of plans are comprised with the improvement of education curriculum, the construction of council between relevant organism, and the installation of subdivision in relevant geographical society. The possibility shaping up the identity of korean military geography as a common literature can be increased by enhancing the study toward peace and humanitarism and specifying the method for development as noted on this study.

This study is to suggest the revitalization plan of military libraries, on the basis of analysis for the military library status and the results of a survey and interview with soldiers and working staff in the military libraries. To this end, first, it analyzes study trends in the operation and revitalization plan of the military libraries based on the preceding research analysis and investigates and analyzes the operation of the military libraries. Second, it identifies problems in the operation of the military libraries by comparing and analyzing between the operation of domestic military libraries and the best cases as well as the operation situation of the overseas military libraries. Third, it suggests the revitalization plan by holistically analyzing the situation and the best cases of the military libraries while finding out the problems through interviews and questionnaires. According to the analysis, first, it is necessary to expand the number of exclusive personnel with librarian qualifications and prepare standards for the placement of librarians. Second, it is necessary to develop online education to provide regular operation education for the personnel of the military libraries. Third, it is necessary to develop common manuals for working staff. Fourth, it is necessary to prepare the plan to expand the preference books of soldiers to increase reading and usage rate of the military libraries. Fifth, it is necessary to construct library space in the form of a book cafe for soldiers' knowledge development and relaxation and to locate the library in a highly accessible place. Lastly, it needs to develop the application of the military library and should lead to high interest in libraries by letting soldiers read books and post book reviews on it after work.
