As cyberspace expands, device-centered digital forensics performance procedures are changing to collect evidence directly in cyberspace. In order for digital evidence to be effectively recognized in court, it must first be legally collected evidence, and then the authenticity of the evidence must be recognized. Our Supreme Court has ruled that in order to be recognized for the authenticity of digital evidence, identity, integrity, and reliability must be recognized. The identity of the evidence means the identity of the original, and the integrity means the circumstances that have not changed since the collection of evidence and submission to the court. Reliability refers to the accuracy and qualifications of the tools and people collected. In order to be recognized for such authenticity, it is necessary to prepare and operate matters to be observed in the entire process of collecting evidence in advanceIf the matters to be observed in the evidence collection process in cyberspace are produced and distributed in the form of guidelines, it will be easy to prove the identity, integrity, and reliability of the evidence when the authenticity of the evidence is controversial in court in the future. In this paper, a detailed performance procedure for collecting public information in cyberspace was proposed. In proposing the performance procedure, detailed procedures were proposed according to the time cloud of collecting evidence on the premise of the criteria for securing the authenticity of evidence. The matters to be considered for each detailed procedure were carefully reviewed, and efforts were made to prepare technical and procedural procedures. 디지털 증거가 법정에서 유효하게 증거능력을 인정받기 위해서는 우선 적법하게 수집된 증거이어야 하며, 다음으로 증거의 진정성이 인정되어야 한다. 우리 대법원은 디지털 증거의 진정성을 인정받기 위해서는 동일성과 무결성, 신뢰성이 인정되어야 한다고 판시한바 있다. 증거의 동일성은 원본과의 동일성을 의미하며, 무결성은 증거수집 이후 법정에 제출되기까지 변경되지 않았다는 사정을 의미한다. 신뢰성은 수집한 도구와 사람에 대한 정확성과 자격을 의미한다. 이와 같은 진정성을 인정받기 위해서는 증거수집 전체 과정에서 준수해야할 사항 등을 사전에 마련하여 운영할 필요가 있다. 사이버 공간에서 증거수집 과정에 준수해야 할 사항을 가이드라인 형태로 제작하여 배포한다면 향후 법정에서 증거의 진정성 여부가 논란이 되었을 때 증거의 동일성과 무결성, 신뢰성을 쉽게 입증할 수 있을 것이다. 본 논문에서는 사이버 공간에서 공개정보를 수집하기 위한 세부 수행절차를 제안하였다. 수행절차를 제안함에 있어서는 증거의 진정성을 확보하기 위한 기준을 전제로 증거를 수집하는 시간적 흐름에 따라 세부절차를 제안하였다. 각각의 세부절차별 고려해야할 사항을 면밀히 검토하였으며, 진정성 확보를 위한 기준과 절차 마련을 위해 노력하였다.

The purpose of this study was to look into the relationships between morality and behavioral regulation of the school sports club participants by exercise behavior change. 3 questionnaires were used for measuring each factor. And were carried out from a total of 480 students who are going to middle and high school located at 16 cities and provinces all over the country. SPSS 20.0n ad AMOS 18.0 program were used for analysis . Those were Chi-Square test, One-way ANOVA, post-hoc(LSD) test , correlation analysis and multiple regression analysis. The following conclusions were drawn. First, concerning the stage of exercise behavior change by school class, the students of middle school were distributed in order of maintenance stage, contemplation stage, precontemplation stage. On the other hand, the students of high school were distributed according to maintenance stage, preparation stage, precontemplation stage. Second, as for the morality, it turned up that there are no any differences depending on the stage of exercise behavior change. But it appeared difference in the terms of behavior regulation. Third, the morality have shown positive-correlation with the of amotivation, the external and the identified regulation. meanwhile, negative-correlation with intrinsic. Fourth, it appeared that the morality is having an effect on the behavior regulation.

첨단 의료영상기기로 영상화된 의료 영상을 이용하여 삼차원 영상을 생성함으로써 질환의 진단을 쉽게 할 수 있게 되었다. 인체의 일부분을 삼차원 영상으로 가시화 하여 질환의 진단에 이용할 때 뼈, 근육, 기관들 중 특정 부위를 제외한 나머지 부위를 제거하여 가시화 하는 방법에 관한 연구는 많이 있었으나 특정 부위의 표면을 제거하고 그 내부를 가시화하기 위한 연구는 거의 없었다. 본 논문에서는 자기공명 영상으로부터 얻은 특정 부위를 표면을 이용하여 내부를 가시화 하기 위해서 표면의 일부를 제거하는 방법과 영상에서 제거된 표면의 면적에 따라 내부로 입사하는 빛의 양을 조절하여 물체의 내부를 가시화하는 방법을 제시하고 실험을 통해 기존의 가시화 방법과 비교한다.

According to the statistical report from National Emergency Management Agency (NEMA) in Korea the accident rate of closed switchboards in power systems occupies over 40%. In this paper an integrated sensor module for monitoring the condition of closed switchboards is described. The sensor module monitors electro-magnetic (EM) wave ultra-violet (UV) ray heat and smoke generated by electrical discharges or insulation breakdown. The effective detection ranges were decided from experiment results; 100 kHz~10 MHz for EM wave 220 nm~395 nm for UV ray and 0~150 ℃ for heat respectively. The prototype sensor module includes all functions above-mentioned in one device.
