Since performance assessment was introduced in Korea in the middle of 1990, many problems which include its definition, characters, methods and scorings etc., raised in mathematics education worlds. Therefore this paper presents the theoretical background of performance assessment in mathematics education. Contemporary teaching and loaming theories reject stimulus-response theory which emphasizes outcome. Performance assessment emphasizes the assessment which reveal learning process and various strategies. And it bases on constructivism and socio-cultural perspective. This paper presents paradigms which guide the roles and purposes of assessment. The paradigms include conventional paradigm, constructivist paradigm and critical paradigm. There is a close correlation between constructivist paradigm and performance assessment. Assessment has to grasp the development of present and the possibility of development of future of the students. Performance assessment must be fixed the new paradigm of education for this purpose.

This study aims to investigate the possibility of Investor-State Dispute under Korea US FTA in relation to Korean environmental impact assessment scheme. The study analyzes the Investor-State Dispute case between Bilcon of Delaware and the government of Canada. The case study shows that Bilcon challenged Canada with violations of NAFTA 1102, 1103 and 1105, arguing that Canada treated Bilcon in an arbitrary and discriminatory manner. The study analyzes two different scenarios that Korea could face with arbitration for alleged breach of its obligations under the Korea US FTA in relation to EIA scheme. From analyzing the case study in relation to two different scenarios, the study finds that problems previously identified and associated with EIA scheme in Korea could directly or indirectly cause Investor-State Dispute Settlement process between Korea and American investors. The study concludes that the risk of violating Korea US FTA related with Korean EIA could be reduced by creating Korean EIA scheme in a transparent and unarbitrary manner which guarantees fair public participation and elaborating the concrete meaning of sustainable development in EIA law.

Site or multi-unit (MU) risk assessment has been a major issue in the field of nuclear safety study since the Fukushima accident in 2011. There have been few methods or experiences for MU risk assessment because the Fukushima accident was the first real MU accident and before the accident, there was little expectation of the possibility that an MU accident will occur. In addition to the lack of experience of MU risk assessment, since an MU nuclear power plant site is usually very complex to analyze as a whole, it was considered that a systematic method such as probabilistic safety assessment (PSA) is difficult to apply to MU risk assessment. This paper proposes a new MU risk assessment methodology by using the conventional PSA methodology which is widely used in nuclear power plant risk assessment. The logical failure structure of a site with multiple units is suggested from the definition of site risk, and a decomposition method is applied to identify specific MU failure scenarios.

The fundamental assumption that thresholds exist for noncarcinogenic toxic effects of chemicals is reviewed; this assumption forms the basis for the no-observed-effect level/ safety-factor (NOEL/SF) approach to risk assessment for such effects. The origin and evolution of the NOEL/SF approach are traced, and its limitations are discussed. The recently proposed use of dose-response modeling to estimate a benchmark dose as a replacement for the NOEL is explained. The possibility of expanding dose-response modeling of non carcinogenic effects to include the estimation of assumed thresholds is discussed. A new method for conversion of quantitative toxic responses to a probability scale for risk assessment via dose-response modeling is outlined.

포오트폴리오 평가란 하나 이상의 주제나 문제에 대한 해결 과정을 모두 기록함과 아울러, 이들에 대한 반성적 자기 평가 결과들을 모아둔 것으로 이를 통해 학생들은 자기 자신의 변화 과정을 알 수 있고 자신의 장점이나 약점, 성실성 여부, 잠재 가능성 등을 스스로 인식할 수 있다. 그리고, 교사들은 학생들의 과거와 현재의 상태를 쉽게 파악할 수 있을 환 아니라 앞으로의 발전방향에 대한 조언을 할 수 있다. 포오트폴리오 평가는 결과만을 중시하는 평가 방법이 아니라 과정 중심 평가 또는 과정과 결과의 통합 평가의 한 대안적인 방법으로 학습자의 자아실현을 위한 발달의 잠재적 가능성을 키워주는 중요한 도구로 이용될 수 있다.

It has become important to evaluate the qualitive reliability and condition assessment of existing structural systems in order to establish a rational program for repair and maintenance. Since most of if existing structural system may suffer from defect corrosion and damage, it is necessary to account for their effects in fuzzy reliability analysis, In this paper, an attempt is made to develope a reliability analysis for damaged structural systems using failure possibility theory. Damage state is specified in terms of linguistic valiables using natural language information and numerical information, which are defined by fuzzy sets. Using a subjective condition index of failure possibility and information of the damage state is introduced into the calculation of failure probability. The subjective condition index of quantitative and qualitative analysis method is newly proposed based on the fuzzy set operations, namely logical product, drastic product, logical sum and drastic sum

For the balanced realization of these values of mathematical culture, we need to innovate mathematics classrooms, for which we need to make use of portfolio assessment. First, portfolio assessment can be regarded as a method of synthesizing a variety of resources for systematic evaluation. Second, portfolio assessment can be used as a tool of building up learners' positive attitude toward mathematics, by which we can identify the latent possibility of learners' development and help them develop confidence in mathematics. Third, portfolio assessment can play an important role as a tool for exploring the method of teaching and learning in which learners recognize the value of mathematics and are interested in mathematical activities, as we have seen in the report on the Gulliver's Travels Project.

The possibility of human error in operation of nuclear power plant has been proved to be one of the most important factors for safety analysis. This study established the HRA methodology according to THERP steps for performing PRA(probabilistic risk assessment) of nuclear power plants and made two sample calculations : Availibility of auxiliary diesel generator, possibility of Davis-Bess #1 accident in 1985.

Environmental Impact Assessment(EIA) is defined as an activity designed to identify and predict the impact on the environment. In the process of an EIA, the quantitative evaluation is generally performed for the air and water quality which have the national environmental quality standards. But the predicted values for the air and water quality are simply compared to the environmental standards. At present, the EIA process of Korea has no consideration for the possible human health risk resulting from the development projects. Environmental Health Impact Assessment(EHIA) is an applied methodology of EIA to estimate the acceptable health risk caused by a specified level of environmental pollutants. Estimating the excessive lifetime risk that is a possibility of dying of a certain disease by environmental contaminants, is useful as an evaluation technique of EHIA. It is recommanded the decision-makers to make efficient use of EHIA not only the development projects but also legislative proposals, policies and programmes in future.
