랜섬웨어 침해사고의 감염대상의 규모를 가리지 않는 특성과 폭발적인 증가세로 인해 전 세계적인 대응방안 마련의 공감대가 형성된 지 오래이다. 침해사고 분석 관점에서 랜섬웨어 사고는 기존 침해사고와 달리 랜섬웨어 악성코드가 사용되었다는 가장 큰 특징 이 외에 별다른 차이가 없다. 여타 침해사고와 동일하게 공격 도구를 생산하고 인프라를 구축하는 단계부터, 타겟 시스템으로의 최초 침투, 권한 상승, 내부 전파를 거쳐 최종적으로 랜섬웨어 악성코드가 실행되는 흐름을 보인다. 한편, 랜섬웨어 공격조직은 보다 원활한 공격을 위하여 점차 분업화, 조직화되는 동향을 보이기 때문에 공급 사슬을 차단하려는 노력도 수반되어야 한다. 본고에서는 랜섬웨어 위협을 공격 타임라인으로 나누어, 산학연관에서 어떠한 방향으로 대응 노력을 기울이고 있는지 소개한다.

This study examines the impact of national economic restructuring on regional development patterns. Korea's development over the last decade has been characterized by a rapid economic restructuring towards the information economy. This economic restructuring has had significant impacts on regional development patterns. The most remarkable feature is a clear coreperiphery disparity in terms of levels of informatization. Seoul showed an extraordinarily high level of informatization. The process of regional development in the information era is marked by an intensified spatial division of labor, which articulates with the pre-existing pattern of regional disparity. Information infrastructrue improvements for regional development do not necessarily result in reductions in regional unevenness. There is an urgent need to develop the integrated regional informatization strategy.

This paper tries to analyze the evolution of technological innovative pattern in system semiconductor industry from the perspective of the evolution of way by which knowledge is generated and its related evolution of inter-firm relationships. In particular, this paper focuses on the evolution of knowledge after the emergence of EDA as a design tool, as a main momentum. As a result of analysis, we can find out following things. First, the innovative activities have evolved from design activity-centered technology development to innovative activities focusing on searching activities for utilizing knowledge and technology. Second, with rising value of knowledge, creation of new market utilizing knowledge, and development of new industry and new technology through inter-firm relationship had been made, in addition to strengthened specialized technological division of labor. Third, with focusing on utilization of knowledge, inter-firm network has taken diverse forms for building complementary platform for co-development. This discussion can give an insight on the necessity of utilizing inter-firm network strategically and setting strategies for enhanced searching activities such as market creation and knowledge utilization.

This study explores how an elementary school homeroom teacher who continued to lecture, can use diversified science teaching methods for learner-centered instruction. Using an auto-ethnographic approach over the course of a year, self-memory data, facebook diaries, class diaries, and interview data of an elementary teacher's day-to-day preparations and practice of elementary science, in the context of a Korean elementary school, were collected. The data was analyzed through cultural historical activity theory, examining how the interplay of key elements (i.e., the subject as a homeroom teacher with instructional expertise, norms, community, division of labor, tools, and goals) was characterized within and across distinct two-activity systems, and how these elements shaped the teacher's teaching methods into either lecture format or diversified teaching. The study revealed that a non-cooperative community, lack of division of labor, and norms that neglect preparation for science class were the elements that perpetuated the lecture format, and that a contradiction between goals and tools occurred in the activity system. However, these elements were able to be transformed into a cooperative community, shared labor, and norms that saved preparation time for both science class and diversified teaching methods, and those changed elements facilitated the teacher in using diversified teaching methods (e.g., experiments, subject-integrated classes, field work), thereby mitigating the contradiction. This study also discusses that diversified teaching methods can be facilitated when dealing with norms, community, and division of labor elements in an elementary school context as well as improving individual teachers' instructional expertise.

A development proposal that maximizes the trend of travel souvenir and articles toward tourism and natural resources through utilization of the Limited Production method was the focus of the present research. First, the flaws of travel souvenir and articles, currently produced in Inje, Kangwon-Do, were identified, as were the regional uniqueness of the area. The comparative advantages of developmental conditions of the above-specified region to various other Si/Kun regions were demonstrated to ascertain the optimal production method of travel souvenir and articles. The results are as follows. Superior supply of,7aw materials necessary for production of wood-worked travel souvenir and articles are abundantly available and the dose proximity of 17 existing workshops self-contain the production capacity to sustain the Limited Production method. Furthermore, the regional governing council conveyed positive attitudes towards the prospect of creating a regional production complex of wood-worked travel souvenir and articles. The results demonstrate that the optimal method of maximizing the trend of travel souvenir and articles toward tourism and natural resources is achieved through systematic collaboration of industry, education, and tourism that promote development, production, and merchandising of Inje's regional travel souvenir and articles.

Railroads have been developed as public transportation and made a great contribution to national economic growth. But after the mid-20th century, its qualities have been getting low because of focusing on the investment and development of cars and airplanes. Its role which is getting the excellent merits on the mass transportation, rapid transit, safety, state period, energy efficiency, and prevention of environmental pollution has been reconsidered. Elements of horizontal alignment are needed in the case where the existing railroad lines should be improved or moved. If its design drawing was lost or damaged, it is impossible to recover. It is not easy to repair for it as disasters. We must understand an existing railroad line to bring a function included a basic geography situation. In this study, we acquire, analyze, and process the digital images of the railroad and then reappear shape of three dimension. And we expect to be utilized to construct the facility information by extracting the alignment elements of existing railroad lines reversely.

As the organization has been coming to specialization and systematization, meetings have been holding for communication among members and deduction of rational outcome. Also process of meeting procedure has been developing. Those on-line meetings are getting grown because the on-line meetings with messenger and chatting are the best examples for overcoming space limitation problem. But, the on-line meetings have unavoidable weak points. The more a meeting is processed, the more point of argument is out of focus and perception of current situation is reduced. Therefore, this thesis proposes and describe that in introduction, think that pre-defined things, analysis and direction of Ontology, in body, draw up a plan how to make ontology to knowledge, and, how to get out of bounds limitation that as make ontology to knowledge. And, design and implementation actual system that organize this ontological Knowledge, and then managing and summarizing visualizing them. Also, in conclusion, after remark and consider this system in which using the ontology based on XML, and proposes conculsion and directional development point.

This study inquired the features of restructuring of shipbuilding industry and structure of community cooperation. The Sinhyeon-eup region has experienced rapid changes as a large shipyard location. Prior to Korea, Japan has developed the cooperation of company-community-residents relationships and the reorganization of location systems through division and accumulation system. The restructuring of shipbuilding industry in Korea have focused on the improvement of business environment. So they have not been efficiently settled in the accumulation and the cooperation structure between company and region. Japan established the organic cooperation structure of company and community before the large restructuring, while the shipbuilding industry city of our country commenced it with the crisis of community by the restructuring. In the Sinhyeon-eup region, The connecting ring among the production sections of a core company in center is established. However the structure of community cooperation is weak. The structure of community cooperation as local governance consist of company, pubic institution, local residents, and regional expert. This structure can be a rational channel in which it can not only strengthen the cohesion of the community, but also solve the present questions of the industrial city.
