인터넷을 통한 기업간(B2B) 전자거래 시장규모가 올해 17조원대에 이르고 기업과 소비자간(B2C) 전자상거래 시장규모 또한 1조원을 넘어서는 등 전체 국내 전자상거래 시장 규모가 18조원을 넘어 설 전망이다. 이는 정보통신시스템에 대한 사회 전반의 의존도가 한층 증대하고 있음을 보여주는 단적인 예라 할 수 있다 오늘날 인터넷 사용이 보편화되고 전자상거래의 규모가 커져 갈수록 정보보호시스템에 대한 신뢰성 및 안전성에 대한 입증 노력 또한 더 강하게 요구되고 있는게 사실이다. 특히 안전성이 입증되진 않은 취약한 정보보호시스템을 사용한 시스템 구축은 오히려 그 위험성을 증가시킬 수 있음을 최근의 많은 해킹사례를 통해 경험한바 있다, 향후 예견되는 이러한 엄청난 사회적 손실을 막기 위한 제도적 노력의 일환으로 미국, 영국, 독일, 프랑스 등 선진국에서는 10여년 전부터 자국의 환경에 적합한 평가기준을 마련하여 정보보호시스템을 평가해오고 있다 본고에서는 정보보호시스템 평가제도와 관련하여 최근의 국제동향과 그에 따른 국내 대응방안을 모색해 보고자한다. 특히 정보보호시스템 평가를 위한 국제기준의 CC(Common Criteria)와 이를 기반으로 맺어진 MRA(Mutual Recognition Arrangement)의 전개과정을 살펴보고 유럽의 상호인정협정인 ITSEC-MRA의 출범배경과 올 5월에 새롭게 출범한 CC-RA체제와 특징적인 모습을 고찰해 보고자한다.

It is just two years that our country drived forward the project acquiring and using the scientific and technological information of the former USSR. The activities acquiring information are necessary to stir up the scientific and technological cooperation with the former USSR. But it is impossible for any man or institution to accomplish the activities acquiring the scientific and technological information of the former USSR, on the whole, considering political and economic confusion, perfect security policy, and 6,000 research institutes in the former USSR and so on. Thus the support of specialists and budgets should be realized in the national level, along with taking a proper step on mutual cooperation between the related institutions.

In light of the recent developments of transitory nature, it is likely that national defense decision-making will be more difficult to make for years to come. In other words, sudden changes in security environment would call into question the basic assumptions on which we have built our national defense planning and increase the number of the uncertain factors in the decision-making process; the subdivision and ramification of national defense management would increase the factors for decision-making and complicate even further the mutual interactions among these factors; the accelerated pace of sophistication and diversification of weapon systems and military technology would increase the risk of failure and system costs geometrically; and the reduced level of acceptance among the people on the sanctification of national defense in proportion to the rapid progress toward a more democratic and industrial society would engender an increased criticism or checking role by the National Assembly or by the mass media. As the changes in national defense environment and conditions create an innumerable number of new tasks, this paper intends to suggest a few core policy measures to improve the quality of national defense decision-making. More specifically, it proposes to 1) eradicate entirely the bureaucratic behavior and tendencies; 2) utilize actively the brain staff for quality assurance of decision-making; 3) and introduce and apply as a whole set, a total system, or an incorporated pack age the PPBEES(Planning-Programming-Budgeting-Executing-Evaluating-System)/LCMM (Life-Cycle Management Model for System Acquision), the OR/SA(Operations Research/Systems Analysis), and DMIS (Defense Management Information System).

Recently, solar power generation shows the significant growth in the renewable energy field. Using the short-term prediction, it is possible to control the electric power demand and the power generation plan of the auxiliary device. However, a short-term prediction can be used when you know the weather forecast. If it is not possible to use the weather forecast information because of disconnection of network at the island and the mountains or for security reasons, the accuracy of prediction is not good. Therefore, in this paper, we proposed a system capable of short-term prediction of solar power generation amount by using only the weather information that has been collected by oneself. We used temperature, humidity and insolation as weather information. We have applied a moving average to each information because they had a characteristic of time series. It was composed of min, max and average of each information, differences of mutual information and gradient of it. An artificial neural network, SVM and RBF Network model was used for the prediction algorithm and they were combined by Ensemble method. The results of this suggest that using a moving average during pre-processing and ensemble prediction models will maximize prediction accuracy.

This research tried to grasp present condition of domestic corporation's society contribution activity and grope desirable direction of society contribution activity hereafter. As analysis result, establishment of the responsible department or human power in charge for society contribution activity is insufficient, and depend on contribution activity of simple donation than to administer program directly, result of contribution activity is not linked with corporation's purpose or result and practical use of network with similar organization for society contribution was proved by low. Desirable direction of domestic corporation society contribution activity is as following hereafter based on analysis result. First, corporation must put in good order inside system with an establishment of the responsible department for society contribution, security of human power in charge and introducing education program for training specialist. Second, corporation must select specific field with capacity that corporation is holding and improve result of society contribution activity as concentrated investment. Third, corporation must construct network with various similar groups and organizations including NPO/NGO and heighten consummativeness of society contribution activity through mutual interchange and cooperation.

This article summarizes the structure of China's current social health insurance system and reviews the development status of China's private health insurance (PHI). China's medical security system is mainly composed of two parts: basic medical insurance (BMI) and PHI. Among them, the BMI provides reimbursement of basic medical expenses for the insured persons according to different proportions. PHI is a necessary supplement to the BMI and provides assistance to the insured persons in the event of illness or accident. By having PHI, people can obtain medical protection outside the coverage of BMI. In the development of PHI in China, the total medical cost is high and the insurance market size is large, but the proportion of PHI expenditure is low and the personal burden is high. Through this Chinese case, it will be helpful for mutual development between Korean PHI and national health insurance, for Korean insurance companies to enter the Chinese market, and for removing the medical burden on the people.

U.S contains the best technology, man power, and big investment in space. It considers space as not only a science and technology related area, but also as an industry and national security related area. Korea's space policy focuses on the development of space systems such as satellites and launch vehicles. Space policy systems of the two countries are also different, causing some discrepancy in mutual interest when we talk about cooperation with the U.S. This study introduced U.S space policy framework and compared it with Korea's policy. It is meaningful in that we can find an effective way of cooperation between two countries.

This paper raised the need to examine how the online education environment triggered by COVID-19 and the smart learning environment can be established in consideration of the improvement of education and learning through learning analysis. Many studies are being conducted in Korea, and the Ministry of Education is continuously striving to build a smart school by promoting strategies for promoting smart education on the way to a talent powerhouse. Nevertheless, there is no unified definition of smart learning, and it can be seen as customized (individualized) learning using smart devices. However, most of the discussions on the construction of smart schools so far have limitations in that they are limited to physical spaces. Accordingly, the opinions of teachers and learners were not sufficiently reflected in the establishment of the facility. This study intends to study smart learning in various departments. In addition, the subjects students in charge of the co-researcher of this study were analyzed. The total number of subjects was 951, and 434 responded to this study survey. In addition, students were well accepting the online environment, and in the future, regardless of COVID-19, research will be presented to improve mutual communication between professors and students in smart learning.
