사이버범죄는 인터넷 가상공간이 사회 전반으로 광범위하게 확대되면서 공격 기술력을 과시하려던 의도에서 최근에는 영리와 일반적인 목적의 범죄로 변화하고 있다. 신택스(Syntax) 기반의 탐지 분석이 가능한 네트워크 및 시스템 공격이 아닌 시맨틱(Semantic) 기반으로 수동적인 탐지와 대응을 요하는 콘텐츠 이상의 공격에 의한 인터넷 사기와 명예훼손, 개인정보 침해, 저작권 침해 등이 일어나고 있다. 시맨틱 기반의 범죄는 컴퓨터 이용자, 즉 인간의 내면적인 취약성을 이용하는 심리적 요인에 근거한다. 이 논문에서는 공개된 사이버범죄를 분석 후 사회적 영향력과 기술적 영향력으로 분류하고 사이버범죄의 심리적 관점에서의 프로파일링 방안을 연구하여 사이버범죄를 그 발생 수에 의하여 분류하였고, 이를 통하여 결국 범죄의 분석과 대응에 소요되는 시간을 줄이는 계기가 될 수 있음을 보이고 있다. Internet is in rapid growth from technology to total social environment, so technical and syntax based cyber crime is evolved but also psychological and semantic based one is showing. In this paper, we analyze the cyber-crime cases announced by police, then classify it into social and technical influence. After that, we study the profiling method on psychological view point of cyber-crimes. We expect that it is possible to classify cyber-crimes into the categories rapidly and take less time to analyze and response.

최근 정보보호분야는 공격기술이 방어기술보다 더 뛰어난 상태이며, 이는 사회공학, 악성코드, 제로데이 공격 등으로 인하여 정보보호 솔루션을 아무리 이용하여도 막을 수 없는 것이다. 그러므로 정보보호를 모든 참여자들이 생활화하기 위한 정보보보인식제고 프로그램 효율적으로 진행하기 위한 방안을 기술한다.

In the casting industry field, a lot of researches have been carried out to maximize soundness and productivity and improve quality of mass produced products. The researches on the optimum mould design by using computer simulation have achieved a lot of accomplishments in the die-casting process especially. Their results are utilized to mass-produce sound products in their field. But there are some difficulties to use the simulation in order to make the design of product and mould. In general, repetitive calculations of computer simulation require much analyzing time in order to make sound design of them. Another difficulty is that only expertise technicians can analyze results of the simulation. In order to solve such a problem, we are building mould design optimization system which consists of knowledge-based module, simulation, optimization module and interactive modeler(it is based on the commercial modeler). By using and interacting between these modules of that system, we can easily make an optimum design of mould and construct the database. This study introduce the general process of the system and connection method between the modules is mentioned above and some examples to apply it to real product.

Ankylosing spondylitis (AS) is a chronic inflammatory disorder, commonly characterized by inflammation of axial skeleton and development of enthesopathies. Tumor necrosis factor inhibitors (TNFi) shows good therapeutic responses in AS patients without good response to non-steroidal anti-inflammatory drugs. Although TNFi are relatively safe for AS patients, serious opportunistic infections, including tuberculosis and fungal infection, could develop. Here, according to our knowledge, we report a first Korean case of pulmonary cryptococcosis in a patient with AS treated with etanercept. A 64 year-old man with AS visited due to a newly appeared pulmonary nodule on a routine chest radiography. He had been administered etanercept for 5 months. Histologic findings of the lung nodule showed characteristic features of cryptococcosis. Etanercept was discontinued and oral fluconazole was administrated, as there was no evidence of central nervous system involvement. After 7 months of treatment, chest CT showed an improvement of the pulmonary lesion.

Most structure engineers give the casting components over-estimated factor of safety without any reasonable foundation due to the worries about the unavoidable defects such as shrinkages and porosity in castings; the engineers have little knowledge on the relation between the defect and structural behavior. And the workers in casting field also do not know how to control the defects by manufacturing; they do not know to where the defects move or until how size they reduce the defects. In this study, shrinkage defect was scanned by industrial computerized tomography instrument (CT), and subsequently was modeled to a spheroid primitive for structural analysis. Using these simplified models of shrinkage, we observed the effects of the defect on the results of the structural analysis. A commercial structural analysis code was used to do the analysis works. Considering the conclusions, it is possible to manage the shrinkages effectively in casting process and to design the products with more reliable

Direct laser sintering (DLS) technology for the resign coated sand is one of attractive technologies to produce molds and cores for the foundry industry rapidly and cost effectively. The objective of this case study is to develop casting pilot models using computer simulation technology, DLS RP machine and industrial computed tomography. The proposed casting design was verified by the Z-Cast software in the fields of fluid flow and solidification during the casting process. Casting parts with aluminum alloy using the post-curing treated sand moulds and cores are accurate to dimension and defect free.
