Recently, in circumstantial situation it is recommended positively to utilize of EIFS(Exterior Insulating and Finishing System) as energy policy for economizing energy. But internal EPS insulators of EIFS are exterior panel of high fire risk, because of constituting of flammable materials to be fragile in fire. In this study, fire risk is assessed by experiment Con Calorimeter test and SBI(Single Burning Item) test. As the result of experiment, Con Calorimeter tests do not reach to capability standard of internal incombustible grade, and are assessed as low grade in SBI incombustible grade. Because EIPS is exterior material in buildings with high fire risk in spite of good efficiency, it is required rapidly to take measures to meet situation through various studies(for instance, adjusting law regulation, etc.) in the future.

This research is significant in terms of estimating the validity by setting evaluation items in view of integrating not only original beauty and visual areas but also natural ecological areas based on questionnaire. The results are as follows. 1) According to literature study, 17 items such as variety, the character of sites in terms of landscape, the beauty of landscape, visibility, and ratio of green visibility are selected. Also, 21 items such as variety of animals and plants species, size of green area, and ecological naturalness are selected in the area of landscape ecological resources. 2) As a result of questionnaire of the group of landscape experts, animals and plants ecological areas show 5.6341, the highest in importance analysis according to assessment areas. Also, as a result of importance analysis on items in each area, for example, in the area of visual resources, the item of skyline analysis is 6.0488, the highest. 3) As a result of corelation of item meaning on landscape effect assesment, for example, meaningness of psychological assessment item and landscape site item indicate 0.710, the highest coefficient correlation. 4) As critical assessment items per unit project, items such as damage minimization of original land features for project in terms of point, ratio of green visibility, variety of animals and plants species marked above 8.0 as high important medium. The project in terms of line, minimization of original land features, preservation of worthy biotope showed high point and the character of sites in terms of landscape, minimization of original land features, the size of green area, and analysis of skyline marked above 8.5 as high importance points. On the contrary, items for climate and soil showed relatively low points.

This article focuses on English language assessment for young learners in Korea questioning how far the special needs of young language learners (YLL) are being catered by the current English language assessments. First of all, this paper identifies the distinctive characteristics of young learners and the related assessments and provides several examples in the European context to explore how European programs apply the distinctive conditions of YLL on the assessing practices at schools. Secondly, four tests of oral proficiency which are currently administered in Korea (SEPT-general vs. SEPT-Junior; ESPT-general vs. ESPT-Junior) are explored to compare how the assessments for YLL take account of the special characteristics of young learners. Test content is analyzed on item types, test criteria and level descriptors. Lastly, suggestions are made based on the analysis of the assessments. It is hoped that this research paper provides meaningful implications on the YLL test development in Korea.

본 연구에서는 보강토 옹벽 점검 자료를 바탕으로 보강토 옹벽의 상태평가항목의 가중치를 새롭게 제안하고 결함점수 및 결함지수 를 제안하였다. 161개소의 보강토 옹벽의 점검결과를 근거로 다중회귀분석과 엔트로피 기법을 이용하여 상태평가항목별 가중치를 산정하였 으며, 또한 전문가를 대상으로 AHP 기법을 활용하여 평가항목별 가중치를 산정하였다. 각 기법에서 도출된 가중치를 활용하여 혼한 가중치를 제안하였으며, 제안 가중치를 토대로 결함점수 및 결함지수를 제안하여 기존 161개소 현장에 적용하여 현재의 가중치와 제안 가중치에 의한 현장별 위험도 순위를 비교 분석하였다. 다중회귀분석, AHP 기법, 엔트로피 기법을 활용하여 분석한 결과 상태평가항목의 가중치 순위가 변동 이 컸으며, 현재 상태평가항목의 가중치와 달리 가중치 순위의 중복은 발생하지 않았다. 특히, 다중회귀분석 결과에서는 특정 상태평가항목이 전체 가중치의 70% 이상을 차지하는 결과가 도출되었다. 제안한 혼합 가중치를 기존 보강토 옹벽 데이터에 적용한 결과, 상태평가항목의 가중 치 중복은 발생하지 않았으며, 대상 보강토 옹벽 161 개소 중 16 개소의 위험도 순위 상승과 31 개소의 위험도 하락이 발생하였다.

Collapse of reinforced earth retaining wall due to improper design and construction is still occurring during construction and operation. While most studies of reinforced retaining walls are focused on the mechanistic behavior, there is little study on the improvement of assessment item, which is used to examine the safety of retaining wall, based on the existed inspection data. This study proposed new weighting factor of assessment item by utilizing multiple regression analysis technique, AHP method, and entropy method for the existed inspection data of reinforced earth retaining wall. Compared to the existed weighting factor, the value and the rank of proposed weighting factors are changed. By applying the proposed weighting factors to the existing retaining walls of 161 sites, fragility region of 47 sites is changed.
