        The purpose of this report is to provide a summary of the Phase 1 Final Status Survey (FSS) Final Report results and overall conclusions which conduct that the Zion Nuclear Power Station (ZNPS) facility and site meets the 25 mrem(0.25 mSv)per year release criterion as established in Nuclear Regulatory Commission Regulation (NRC) 10 CFR 20.1402 “Radiological Criteria for Unrestricted Use”. The FSS results provided assessment and summarize that any residual radioactivity results in a Total Effective Dose Equivalent (TEDE) to an Average Member of the Critical Group (AMCG) that does not exceed 25 mrem per year, and the residual radioactivity has been reduced to levels that are as low as reasonably achievable (ALARA). The release criterion is translated into site-specific Derived Concentration Guideline Levels (DCGLs) for assessment and summary. ZionSolutions, a decommissioning service provider, estimates that a total of four (4) FSS Final Reports be generated and submitted to the NRC during the decommissioning project. ZionSolutions established the Characterization/License Termination (C/LT) Group, within the Radiation Protection division, with sufficient management and technical resources to fulfill project objectives. The C/LT Group is responsible for the safe completion of all surveys related to characterization and final site closure. Approved site procedures and detailed Technical Support Documents (TSD) direct the FSS process to ensure consistent implementation and adherence to applicable requirements. The development and planning phase was initiated in 1999 by the “Zion Station Historical Site Assessment” (HSA) and the initiation of the characterization process for FSS. Develop the information necessary to support FSS design, including the development of Data Quality Objectives (DQOs) and survey instrument performance standards. DQOs are qualitative and quantitative statements derived from the DQOs process that clarify technical and quality objectives. The next step, FSS design utilizes the combination of traditional scanning surveys, systematic sampling protocols and investigative/judgmental methodologies to evaluate survey units relative to the applicable release criteria for open land sample plans. To aid in the development of an initial suite of potential radionuclides of concern for the decommissioning of ZNPS, the analytical results of representative characterization samples collected at the site were reviewed. At this FSS design step, the Radionuclides of Concern (ROC) are determined. As Co-60 and Cs-137 account for 99.5% of the analysis results of concrete core sampling data form ZNPS’s Containment Building and Auxiliary Building, they are determined and used as the basic ROC in the survey design. Additionally, site information is described and Historical Site Assessment (HSA) is performed. Data collected for the initial HSA will be used to establish the initial regional survey unit and corresponding MARSSIM classification. Next, an assessment of the collected data is performed using the DQO process, and a survey methodology is established by selecting a sampling method and measuring instrumentation. These result judgments provide guidance for C/LT Engineer to interpret findings using the Data Quality Assessment (DQA) process, which analysis Recorded data, Missing values, Deviation from established procedure, and Analysis flags. In conclusion, FSS is the process used to demonstrate that the ZNPS facility and site comply the radiological criteria for unrestricted use specified in 10 CFR.20. The purpose of FSS Sample Plan is to describe the methods to be used in planning, designing, conducting, and evaluating the FSS.

        본 논문에서는 주파수 선택적 투과막(FSS)이 결합된 복합재료 구조에서 구성 재료 간의 열팽창계수 차이로 잔류응력이 발생하므로 이로 인한 층간분리나 FSS의 손상 등 구조적인 파손 가능성과 잔류응력으로 인하여 변형된 FSS가 전파투과특성에 미치는 영향에 대하여 연구하였다. FSS는 단위요소의 종류, 설계변수, 배열에 따라 전파특성이 다르게 나타나므로, PSO 알고리즘을 이용하여 다이폴이 목표주파수에서 투과특성을 갖도록 설계하고 그 설계치수를 다른 N-pole 종류 단위요소(Tripole, Cross dipole, Jerusalem cross)에 적용하여, 복합재료 구조에 발생하는 잔류응력과 그로인한 구조적 손상과 전파특성을 영향성을 관찰하고 FSS패턴과 복합재료의 적층 변화에 따라 비교하였다.

        Eighteen years have passed since Korea introduced plant variety protection (PVP) system. Korea is being considered as one of the countries which introduced PVP system successfully. However, there have been lots of changes in circumstances surrounding PVP system during this period. Regarding future direction of PVP system in Korea, firstly the function and role of three organizations which now independently operate PVP system need to be reorganized to improve efficiency in PVP operation dealing with global issues. Secondly, authorities need to devise more user-oriented application form and process. This is because breeders feel some difficulties in preparing application documents. Thirdly, Korea has to create sound environments which guarantee effective enforcement of breeders’ rights and secure reliability of the system against infringement. Regarding decision of infringement, a reasonable threshold should be set up to decide whether certain varieties are different from protected varieties or not using both growing test and DNA test. For essentially derived varieties (EDV), authorities need to establish a reasonable threshold to decide whether there is an essential derivation or not. In addition, to prevent dispute between PVP holders and farmers regarding the use of farm saved seeds in the future, clarification of farm saved seed article in legislation is necessary. Lastly, there might be some contradiction between PVP and Nagoya protocol in disclosure of origin, prior informed consent, benefit sharing, etc. In advance of enactment of domestic ABS law, authority needs to study impact of Nagoya protocol on PVP system to minimize confusion and damage on breeders.

        본 연구의 목적은 한국설정에 맞는 스포츠 몰입상태 측정을 위한 도구의 타당도와 신뢰도를 검증하는데 있다. 연구대상자는 대학·고교 운동선수, 체육전공학생과 동호회 가입 학생들이었으며, 측정도구는 Jackson & Marsh(1996)가 개발한 몰입상태척도(Flow State Scal; FSS)를 사용하였다. FSS 설문지는 9개의 하위요인을 구성되었으며, 각 요인별 4문항씩 총 36문항으로 구성되었다. 이 FSS를 1, 2차에 걸쳐 조사를 실시하여 한국어판 FSS가 개발되었다. 한국어판 FSS의 신뢰도(Cronbach`α) 계수는 7개 하위요인에서 .61∼.81로 높게 나타났으며, 한국어판 FSS는 7개 요인구조를 보였으며, 설명변량으로 66.4%로 나타났다. 또한 확증적 요인분석을 통해 한국어판 FSS질문지로 측정한 몰입상태 측정모델이 적합함을 살펴보았다. 한국어판 FSS의 기초 적합도 지수(GFI)는 .89로서 일반적으로 수용되는 .90에 거의 근접한 것으로 측정모델에 적합한 것으로 나타났다. 조정 적합도 지수(AGFI)의 경우 .84로 적합한 것으로 나타났다. FSS는 이러한 타당성과 신뢰성 검증과정을 거쳐 한국어판 몰입상태 설문지로 완성되었다.
