There are various attacks such as tampering, bypassing and spoofing which are caused with system-wide vulnerabilities of Windows operating system. The underlying operating system is responsible for protecting application-space mechanisms against such attacks. This paper provides the implementation of mandatory access control known as multi-level security (MLS) rating with TCSEC-B1 level on th kernel of Windows$^{TM}$. By adding especially the protection feature against tampering memory of processes to the security kernel, this implementation meets the responsibility against system-wide vulnerabilities.

Objectives: To analyze the radiologic results of patients treated with bone defects treated with beta-tricalcium phostphate (β-TCP) in orthopedic surgery. Methods: Medical records of 49 patients, consisting of 24 (49.0%) men and 25 (51.0%) women were retrospectively reviewed. Graft incorporation was evaluated based on Irwin's radiologic staging. Results: The explanatory power of the total regression equation in Irwin's stage at 3 months postoperatively according to three explanatory variables, namely graft tightness, age at diagnosis, and lesion volume, was 65.6%; the explanatory power of Irwin's stage at 6 months postoperatively according to two variables, namely lesion volume and graft tightness, was 32.9%; and the explanatory power of Irwin's stage at 9 months postoperatively for two variables, namely longitudinal lesion length and graft tightness in the total regression, was 30.8%. Conclusions: Graft tightness, lesion volume, age at diagnosis, and longitudinal lesion length are the common factors affecting graft incorporation.

본 연구에서는 제조업체의 기술 수준을 평가하는 방법을 제시하였다. 기업의 기술수준은 기업이 소유한 제품 및 제조기술 자체뿐만 아니라 기술개발 능력을 나타내는 기술개발 체제 및 기술에 따른 경제적 성과를 나타내는 재무분석에 의해서도 평가되어야 한다. 본 연구에서는 이러한 항목들을 고려하여 평가 모형을 개발하였으며 이 모형을 커넥터 제조업체의 기술수준 평가에 적용하였다.

In this paper, we propose a LiDAR driver that virtualizes multiple inexpensive LiDARs (Light Detection and Ranging) with a smaller number of scan channels on an autonomous vehicle to replace a single expensive LiDAR with a larger number of scan channels. As a result, existing SLAM (Simultaneous Localization And Mapping) algorithms can be used with no modifications developed assuming a single LiDAR. In the paper, the proposed driver was implemented on the Robot Operating System and was evaluated with an existing SLAM algorithm. The results show that the proposed driver, combined with a filter to control the density of points in a 3D map, is compatible with the existing algorithm.

NIR(New Inspection Regime, hereinafter NIR) relating to the PSC(Port State Contorl, hereinafter PSC) has implemented in Asia-Pacific region under Tokyo-MOU from last January 2014. The most noticable difference between NIR and existing TF(Target Factor, hereinafter TF) is to evaluate company performance and to conduct PSC with flexible inspection interval on the basis of Ship Risk Profile; High Risk Ship, Standard Risk Ship and Low Risk Ship.

The purpose of this study is to deduce the effective improvement plans of engineering education system and to provide the base materials by analyzing satisfaction and problems in the perception survey of stakeholders related in engineering education system including Engineering Education Accreditation System. Engineering education system improvement plans from the results of study are as follows. First, government and university should provide more financial support to the college in order to improve education environment such as laboratories and equipment. Second, in order to improve links among engineering education stakeholders, student-professor, student-faculty, and colleges should operate effective mentoring program and consultation plan. Third, according to service quality evaluation, colleges need to give rewards to distinguished faculties for their outstanding work and build up job training about services in order to enhance satisfaction of students and professors, Also, business related to Engineering Education Accreditation System should be simplified and needs to increase the number of workers exclusively responsible for this work. Forth, in order to enhance comprehension of learning outcome and outcome of Engineering Education Accreditation System, it is necessary to improve Engineering education innovation center's status, to establish active systematic promotion system and to operate engineering education evaluation expert committee such as 'Engineering education system evaluation council'. Fifth, because of the stakeholder's shortage of benefits and tiredness accumulation, the issue of effectiveness in engineering education institutions has raised controversy. Thus, engineering education institutions needs to take measure necessary. Moreover, engineering education improvements should be improved by reflecting opinions from professors, faculties and students who are practically planning, operating and participating engineering education programs.

대학의 생명은 대학운영의 자율성이다. 대학 외부의 대학에 대한 통제와 간섭은 대학의 창의적인 교육과 연구활동을 위축시키고, 그 결과 국가와 대학의 발전을 저해한다. 새로운 기구의 신설로 인한 예산이나 인력의 소요보다는 기존의 기구에 대한 정비·확장과 대학평가기관 간의 유기적인 평가체제 구축을 통한 기능의 활성화를 기하는 것이 국가와 대학의 발전에 기여할 것이다. 따라서 정부로부터 독립된 자율적인 기구로서 공정하고 객관적인 평가를 실시하여 그 결과로 신뢰도를 확보할 수 있을 것이다.
