Preliminary surface soil Derived Concentration Guideline Levels (DCGLs) were derived conforming to the Multi-Agency Radiation Site Survey and Investigation Manual (MARSSIM) procedure for the site release and reuse of Kori Unit 1 in Korea. Based on the decommissioning experiences of the U.S. nuclear power plants, a suite of residual radionuclides was determined, and uncertainties contributed to the resultant dose by the input parameters were quantified via the sensitivity analysis of parameters. The peak of the mean dose was obtained via the probabilistic analysis of the RESRAD (RESidual RADioactivity)-ONSITE code. Consequently, $DCGL_w$ of Kori Unit 1 in accordance with two scenarios, industrial worker and residential farmer scenario, were derived and the results were compared respectively with other NPPs. It could be used as a basic guideline for establishing regulatory standards for reuse planning, designing the site characterization surveys and implementing final status survey (FSS).

The aim of this paper is to analyze the development of effective online Problem-Based Learning (PBL) and Project-Based Learning (PjBL). The collaborative PBL/PjBL become one of the hot issues with the rapid growth of online learning in the era of COVID-19. Educators try to get innovative to continue instruction without sacrificing student engagement, thus adopting an instructional model of PBL/PjBL. The PBL process involves clarifying terms, defining complex problems, brainstorming, structuring and hypothesis while PjBL includes project-planning, implementation, communicating the results of a project in a presentation and evaluations with immediate individually tailored feedback within a predetermined period. Despite the differences between online and offline learning, the benefits of learning online or offline are practically the same if enough bidirectional interactions between instructors and students are possible. We argue that online qualifications are just the same as those of offline ones in PBL/PjBL models, therefore, the standards of online/offline learning are identical since education is a two-way communication.

Markov chains and Monte Carlo Simulation were applied to account for the probabilistic nature of pavement deterioration over time using data collected in the field. The primary purpose of this study was to evaluate pavement network performance of Western Australia (WA) by applying the existing pavement management tools relevant to WA road construction networks. Two approaches were used to analyze the pavement networks: evaluating current pavement performance data to assess WA State Road networks and predicting the future states using past and current pavement data. The Markov chains process and Monte Carlo Simulation methods were used to predicting future conditions. The results indicated that Markov chains and Monte Carlo Simulation prediction models perform well compared to pavement performance data from the last four decades. The results also revealed the impact of design, traffic demand, and climate and construction standards on urban pavement performance. This study recommends an appropriate and effective pavement engineering management system for proper pavement design and analysis, preliminary planning, future pavement maintenance and rehabilitation, service life, and sustainable pavement construction functionality.

본 연구는 식품의약품안전청에서 2005년도 생식류에 대한 미생물 기준이 제정됨으로 관련 미생물에 대한 기준규격이 적절히 실행되고 있는지를 파악하기위하여 모니터링을 실시하였다. 생식류의 미생물적 기준규격은 E. coi 음성, B.cereus 1 g당 1,000 이하이며, Cl. perfringens 1 g당 100 이하로 규정하고 있다. 따라서 시중에 유통 중인 생식류를 수거하여 E. coli, B. cereus, Cl. perfringens 및 세균수에 대한 모니터링을 진행하였다. E. coli는 99건 모두 음성으로 분석되었으며, B. cereus의 경우 56건(57%)에서는 음성이며, 42건(42%)에서 최소 100 cfu/g부터 최대 900 cfu/g으로 나타났다. 그리고 1건에서 기준규격을 초과하는 3,500 cfu/g이 검출되었다. Cl. perfringens의 분석결과는 98건(99%)에서는 음성으로 분석되었으며, 1건(1%)에서 10 cfu/g로 나타났고 세균수의 경우 검체별로 최소 10 cfu/g부터 최대 $5.3{\times}10^7cfu/g$으로 나타났다. 위의 결과로부터 특정제품을 제외하면 식중독 미생물의 경우는 비교적 위생적으로 처리되고 있음을 알 수 있었으나 B. cereus와 세균수의 경우 좀 더 위생적인 관리가 필요한 것으로 판단된다.
