Liquefaction of soil foundation is one of the major seismic damage types for infrastructures. In this paper, deterministic and probabilistic approaches for the evaluation of liquefaction potential are briefly summarized and the risk assessment method is newly proposed using seismic fragility and seismic hazard analyses. Currently the deterministic approach is widely used to evaluate the liquefaction potential in Korea. However, it is very difficult to handle a certain degree of uncertainties in the soil properties such as elastic modulus and resistant capacity by deterministic approach, and the probabilistic approaches are known as more promising. Two types of probabilistic approaches are introduced including (1) the reliability analysis (to obtain probability of failure) for a given design earthquake and (2) the seismic risk analysis of liquefaction for a specific soil for a given service life. The results from different methods show a similar trend, and the liquefaction potential can be more quantitatively evaluated using the new risk analysis method.

먹는 것이 아니어서 유전자변형작물(GM작물)로서의 거부감이 덜할 뿐 아니라 고부가 창출가능성이 높아 최근 GM 화훼류 개발에 대한 관심이 높아지고 있다. 이러한 연구 환경에 맞춰 농촌진흥청에서는 형질전환 기술을 이용하여 일반적인 교잡 육종 기술로 개발하기 쉽지 않은 불량 환경인 고염도와 물이 공급되지 않은 조건에서도 견디는 능력이 탁월하게 증진된 장미를 개발했다.

This study aims to develop two science education programs using Angbuilgu and ancient astronomical data, are Korean astronomical heritage, and explore its educational possibility through the pilot application. Considering the TSK compositional characteristics of Angbuilgu and ancient astronomical data, linkage with science curriculum, and linkage with NOS, Angbuilgu was developed as a hands-on activity for elementary school students and ancient astronomical data as a science inquiry activity for middle and high school students. The educational availability of the developed program was confirmed by pilot application to elementary and high school groups. Through the Angbuilgu activity, the students refined their conceptual knowledge by correcting misconceptions about the solar motion by season and then confirmed the possibility of connection with the concept of the celestial coordinate system. Students recognized the scientific value of Angbuilgu and understood the nature of interactions STS. In the ancient astronomical data activity, students experienced inductive and deductive inquiry methods and utilized various information and strategies. Through the activities, students improved their scientific understanding and attitude towards TSK.

The purpose of this research is to investigate the principles for the development of mathematics textbook based on storytelling through literature review, textbook development, and classroom implementation. Mathematics textbook based on storytelling has been developed to help students learn mathematics interesting and meaningful. The principle for the development principles include as the principle of context, process-oriented, communication, and diversity. The developed mathematics textbooks was implemented in high school mathematics classes in order to investigate the effectiveness of the textbooks. We analyzed the data collected by the survey and the interview to find that the mathematics textbook based on storytelling had positive effect on teaching and learning of mathematics. We discussed the implication for the future development and implementation of mathematics textbook based on storytelling.
