고성능 양자 컴퓨터가 개발될 것으로 기대됨에 따라 잠재적인 양자 컴퓨터의 공격으로부터 안전한 양자 후 보안 시스템을 구축하기 위한 연구들이 진행되고 있다. 대표적인 양자 알고리즘인 Grover 알고리즘이 대칭키 암호에 적용될 경우 보안 강도가 제곱근으로 감소되는 보안 훼손이 발생한다. NIST는 대칭키 암호에 대한 양자 후 보안 요구사항으로, 암호 알고리즘 공격에 요구되는 Grover 알고리즘 비용을 기준을 기준으로 양자 후 보안 강도를 추정하고 있다. 대칭키 암호를 공격하기 위한 Grover 알고리즘의 비용은 대상 암호화 알고리즘의 양자 회로 복잡도에 따라 결정된다. 본 논문에서는 NIST 경량암호 공모전 최종 후보에 오른 Sparkle 알고리즘의 양자 회로를 효율적으로 구현하고 Grover 알고리즘을 적용하기 위한 양자 비용에 대해 분석한다. 마지막으로, NIST 양자 후 보안 요구사항과 분석한 비용을 기반으로 경량암호 Sparkle에 대한 양자 후 보안 강도를 평가한다. 양자 회로 구현 및 비용 분석에는 양자 프로그래밍 툴인 ProjectQ가 사용되었다.

Data Envelopment Analysis (DEA) is a theoretically sound framework for performance analysis that offers many advantages over traditional methods such as performance ratios and regression analysis. Largely the result of multidisciplinary research during the last three decades in economics, engineering and management, DEA is best described as an effective new way of visualizing and analyzing performance data. Besides, overseas information technology companies have aggressively tried to enter the domestic market. In the age of globalization and high competition, it is imperative that the system integration (SI) companies need to introduce the performance evaluation models of SI projects, including Capability Maturity Model and Software Process Improvement and Capability Determination, to gain a competitive advantage. Therefore, it makes our research regarding evaluation of SI projects very opportune. The purpose of the study is not only to evaluate efficiency of each project by DEA but also to gain insight into various factors such as project complexity, team members' man-months structure, and process index(project management index) that link to the projects performance.

In order to minimize occupational accidents at worksites, the government is proposing and operating various safety and health policies. The safety and health management capabilities of domestic workplaces vary greatly depending on the size of the workplace, and in particular, safety management is difficult in workplaces with fewer than 50 employees, resulting in a relatively high accident rate. Therefore, the government is operating the safety and health technical support project for small business sites to establish safety and health in small business. In this regard, this study provided a plan for substantiating the safety and health technical support project. through the condition survey of the workplace.

The installation and performance test of the ISOL (Isotope Separation On Line) system for the generation and separation of Rare Isotopes (RI) beams is in progress at the Rare Isotope Science Project (RISP), Institute for Basic Science (IBS). The various RI beams generated by the ISOL target/ion source go through the beam lines and separators, and only the RI beam desired by the user is selected and transmitted to the superconducting linear accelerator at the downstream of the ISOL. In the ISOL system, two separators are installed to separate a specific RI beam, and control is performed by the Experimental Physics and Industrial Control System (EPICS). In this study, an EPICS IOC (Input-Output Control) was developed to measure the magnetic field of a dipole magnet for mass separation of a multivalent (n+) RI beam in the A/Q separator, which is one of the ISOL RI beam separators. The operational stability of the A/Q separator was tested through a magnetic field measurement using a Hall probe.

This study examines the effects of student-centered project-based learning for the development of creative problem-solving skills, communication skills, critical thinking skills, and cooperation. A college students' creative personality test was used and pre-and post-test were performed. and TOEIC Speaking practice test by Educational Testing Service were selected to measure the English communication skills. The SPSS 18.0 was used and validated at a significance level of 5%. The result of this study shows that in the case of 'independence', the post-test average of the experimental group was statistically significant at the significant level (p<.01), which also showed statistically significant difference. There was statistically significant difference between the control group ($M=127{\pm}08.2$) and in the experimental group ($M=132{\pm}18.7$) applying project-based and problem-based convergent learning to English class were positively changed.

At the present time, no systematic review has been conducted to report the project's outcomes or trends. This study systematically reviewed existing evidence related with community care pilot project. A total of 61 articles, including 18 original literatures and 43 review literatures were finally selected. For original literatures, the most frequent literatures focused on demand surveys (n=4) and model proposals (n=4), the utilization of touchpoint (n=3), space design and architectural model (n=3), manpower training and role establishment (n=2), followed by prioritizing objectives (n=1) and research trend study (n=1). For review literatures, the most frequent literature focused on the elderly (n=12) and relatively few literature on the disabled and mental illness (n=2). Since the pilot project for community care has been implemented for only about one year, the present study indicates that more future research is needed to the disabled, mental illness, and homeless should be conducted as well as elderly.

This study deals with the credibility of citizens when investing in uncertain project companies, as well as the Social Performance Compensation Project (SIB) and the IT sharing economy. This allows the convergence of the three sectors to address investment inequalities in economic effectiveness and social security. Activates the model of the overall Social Impact Bond (SIB) process that successfully activates the exchange of information. The empirical presentation of the operations and techniques for social IT service finance examines how the innovation ecosystem can be created with social performance and reward projects. The analysis shows that small sharing institutions or citizens can participate directly to create the ability to connect with private investors, identify the possibility of recognizing non-shared barriers to participation, and show the great impact of citizen trust in IT sharing projects in uncertain areas. As a result, for the sake of social sharing and IT cooperation promoted by the City of Seoul, before the project has the ability to design directly, it will be responsible for reliability and safety in the planning of the project. Therefore, non-shared citizens can also participate in the platform that has been effectively constructed and created.
