        우리나라의 '해양오염방제 자재·약제의 성능시험기준 및 검정기준 중 ‘생물에 대한 영향시험’(생태독성시험)의 시험방법과 판정 기준의 개정과 관련한 방향을 제시하기 위해 현행 기준의 문제점을 파악하고 국가별 제도 비교를 통한 개선방안을 제시하였다. Skeletonema costatum을 이용한 성장저해시험의 경우, 배양액 색조를 비교하여 판단하는 기준 대신 측정된 성장률을 적절한 통계기법을 이용하여 비교 분석하는 과학적인 기준이 도입되어야 하며 시험기간의 경우, 지수성장기를 고려하여 4일 이내가 합당한 것으로 판단된다. 어류를 이용한 독성시험의 경우, 다양한 물질에 대한 독성시험 및 비교연구를 통해 방제 자재에 대해 일관되고 적절한 민감도를 나타낼 수 있는 보다 적절한 어체크기에 대한 재설정이 필요하고 이에 따른 합리적이고 객관적인 판정기준이 마련되어야 할 것으로 판단된다. 시험종의 경우, Artemia sp. 대신 해양 윤충류인 Rotifer, Brachionus plicatilis가 대안이 될 수 있으며 어류시험의 경우, 굴류(Oyster)와 같은 이매 패류의 분류군을 이용한 독성시험으로의 대체 역시 대안으로 고려될 수 있다. 마지막으로 해양오염방제 자재·약제의 형식승인 시험과 관련하여 생태독성시험 분야의 경우, 업무의 특수성과 결과의 신뢰성을 고려하여 별도의 공인시험기관 지정 또는 관련 유사 법률과 연계한 일원화된 창구가 필요하며 수용가능한 수준의 시험비용 산정과 시험항목 조정을 통한 합리적인 제도개선이 필요할 것으로 판단된다.

        HPT research studies and practices have been largely conducted in the corporate setting, leaving education as a neglected context despite its strong emphasis on performance in teaching, learning, and school management. In this study, we examine the application of the HPT standards and their effects on Korean teachers’ performance goal achievement for students. With HPT standards, we also investigate the interaction effect of teacher tenure on the relationship among HPT standards and goal achievement. The Hayes Process Model is adopted to examine the second-stage moderated mediation model. The findings support that the principle standards positively mediate the effect of the process standards on the teachers’ goal achievement, and teacher tenure moderates the HPT standards’ effects on goal achievement. The practical and theoretical implications of the results are discussed, as well as limitations and future research suggestions

        The objective of this study is to construct the inspection standards of motorcycle brake system performance. Based on the Korean Motor Vehicle Safety Standards (KMVSS), the Korean Motor Vehicle Inspection Standards (KMVI), the inspection standards of the International Motor Vehicle Inspection Committee (CITA), United Kingdom and Japan, three alternative brake performance criteria were suggested. The brake performance tests for 129 various models of used motorcycles were conducted for verifying the developed test equipment and suggested three alternative criteria. The total brake performance criterion is appropriately suggested to set at 50 %. Considering the KMVI or the CITA, the brake performance criterion of rear axle may suggested to set at 20 % or 25 %, either.

        A research was conducted on Seoul regional elementary, middle, and high school nutritionists to study about their perception of HACCP control standards & performance conditions and sanitation & safety inspection, to seek for more efficient methods of school meals' sanitation system settlement. All surveys were distributed and collected via email. A total of 305 survey papers were collected, and out of these, 300 school results were analyzed. As for CCP 1 performance conditions, 43.3% of the nutritionist put emphasis on temperature control for cooking duration and 71.0% said that they manage both temperature and PHF food control. In CCP 2 stage, 65.8% of the nutritionists maintained the food's temperature, and 56.7% documented the recordings after cooking. A total of 79.3% of the schools scored above 90 points on school meal sanitation & safety inspection, 3.72 points on necessity for revisions, 3.38 points on objectivity, and 3.34 points on reliability. As for these results, a clear CCP control criteria as well as training must be set. Also, because the necessity of revision for sanitation & safety inspection is higher than reliability and objectivity, appropriate complementary measures must be taken.

        This study attends to the importance of performance standards in teacher education and evaluation system and suggests a primitive guideline for English teaching standards in Korea. For this purpose, first of all, the notion of ""teaching expertise"" and ""performance standards"" are reviewed with the previous studies. Second, this study introduces recent changes in Korean teacher education programs and some efforts to develop Korean teacher standards. Third, teaching standards (for ESL/WL) established by NCATE, NBPTS, and INTASC are reviewed to investigate their domains, standards, and evaluation rubric. Finally, this study addresses some implications and suggestions for establishing English teacher standards in Korea. It is hoped that the findings of this study provide subject-specific information on teacher training and assessment to teacher researchers and education policy makers in Korea.
