Contemporary concrete structures make use of underground spaces as parking lots and other comfort facilities for efficiency purposes. As underground environmental conditions are in constant exposure to degradation factors from the environment such as groundwater, hydraulic and soil pressure, structural movement and settlement, structural defects in the form of leakage occur. Current maintenance regulations and regimes are unable to respond to this field, as degradation mechanisms in underground environments are still unclear. In this regard, this study proposes the utilization of integrated information sharing system that can provide various technical information for construction designs to prevent leakages in underground concrete structures.

Business integration has been considered as one of the most critical success factors that enable the firms to gain competitive edges. Despite this trend, it has also been found among not a few companies that the activities that should be functionally tied with are performed even independently. In this study, an integrated model of production planning and inventory has been developed. Computerization of the production planning activities is proposed and implemented. We also proposed the reasonable inventory levels of each item using historic data of the items, which are composed of safety stock from the given fill-rate, operating stock from the production patterns, and reserved stock from the production planning. This study has helped the firm to have clearer job definition of the related processes, to tightly control the inventory by setting and tracing the reasonable fill rates for every product, and to quickly respond to the market changes through the computerized production planning process.

Character education is an important educational purpose in the current situation of secondary mathematics education. In the current mathematics curriculum, character education is mentioned in terms of core competencies. However, it is very difficult to concretely practice character education in secondary mathematics education. This paper examines the theoretical background of character education in the tradition of mathematics education, and suggests that mathematics is regarded as a practical tradition by the nature of mathematics from a value-intrinsic perspective. In this respect, mathematics education is defined as an intrinsic and nurturing character through long history of practice. This paper searched for an integrated approach to practicing character education in of secondary mathematics education, and argued that the teacher's personal approach including the class model approach of the human factors by an example of the exponential law a^maⁿ = a^m+n and the value-oriented activities according to the nature of the mathematics was the core.

The molecular reorientations and surface morphologies of rubbed films formed from atactic polystyrene (PS) samples with various molecular weights were investigated in detail. Previously unknown surface topography features were newly discovered in rubbed films, depending on molecular weights: submicroscale groove-like meandering structures composed of fine-grooves like pebbles in tens nanometers are present, oriented perpendicular to the rubbing direction. The vinyl main chains, however, were preferentially reoriented along the rubbing direction and the planes of the phenyl side groups were preferentially reoriented perpendicular to the rubbing direction with para-directions that were positioned nearly normal to the film plane. Nematic liquid crystal (LC) molecules were found to always align on the rubbed PS surfaces along the orientation direction of the submicroscale grooves generated by rubbing.

This study purposed to examine the effects of integrated activities based on wordless picture books on increase in children's creativity. As for the subject of this study, 20 five-year old children(9 boys and 11 girls), who go to D Kindergarten in Ulsan-si, were selected as a experimental group and 20 five-year old children(8 boys and 12 girls) as comparative group, who attend B Kindergarten in Ulsan-si. For this study, all children of the groups were taken pre-test. After this experiment, difference in creativity of two groups was examined through post-test. The total of 42 sessions were conducted for 14 weeks from the first week of April to the second week of July, 2005. The test tool for this study was Creativity Scale developed by Kim Sang-yun (2003). To verify study questions, the mean of the two groups and the standard deviation were calculated and independent-sample t-test was carried out using SPSS WIN 11.5. The results of this study were as the following: First, integrated activities based on wordless picture books showed statistically significant difference in children's creativity between the experimental group and the comparative one(p<.001), which suggested that the activities affected increase in children's creativity in general. Second, integrated activities centering around wordless picture books indicated statistically significant difference in fluency(p<.05), flexibility(p<.01) and originality(p<.001), sub-factors of children's creativity, between the experimental group and the comparative one. This result revealed that these activities were effective. Third, integrated activities based on wordless picture books did not show significant difference in elaboration, a sub-factor of children's creativity, between the two groups. As the result of this study, integrated activities based on wordless picture books had positive effects on increase in children's creativity.

디지털 기술의 발전으로 컴퓨터와 정보 통신 기술이 결합하여 하나의 시스템에서 다매체 즉 인터그레이티드 미디어(Integrated media)를 가능케 하였다. 인터그레이티드 미디어는 통합적 미디어에 의한 정보 전달방법으로 인간의 정보 전달 체계와 가장 유사한 형태로 발전되어 왔다. 따라서 인터페이스 분야에서도 형태적인 발전에 따라 인간과 컴퓨터의 상호작용(Human Computer Interaction)이라는 중요한 테마로 발전하였다. 인터페이스의 형태적 발전은 디자인 분야에서도 재정립되고 있지만 많은 분야의 동시 접목과 제품개발에 있어 체계성 부족으로 활용이 지체되고 있다. 본 연구는 MP3 자판기 개발 사례를 바탕으로 정보전달 형태 개발을 위한 요소들을 재구성함으로써 인터페이스의 새로운 모델을 구축하기 위한 시도이다. 체계적인 분류를 위하여 인터페이스를 인지적인 면과 조형적인 면을 분류하고, 하드웨어와 소프트웨어로 분류하여 누구나 쉽게 이해할 수 있도록 정립하였으며, 결과적으로 새로운 통합적 인터페이스(Integrated Interface)의 패러다임(Paradigm)을 제시함으로써 디자인의 새로운 방향 즉 통합적 아이덴티티를 구축을 위한 기본 틀을 제시하였다.

The aim of this paper is to review integrated assessment studies conducted to address the impacts of climate change sea-level rise on agricultural sector and to derive suggestions for improving the integrated assessment process to assist decision-makers in establishing climate change adaptation policy. We collect integrated assessment studies which are based on the impact-pathway analysis, compare their step-by-step procedures and identify main factors addressed in each step. The assessment process is typically carried out in the sequence of scenario development, determination of assessment scope, physical impact assessment, economic analysis and synthesis of the outcomes from each step. We identify two types of integrated assessment. The first one examines the impacts of changes in temperature and/or precipitation on the crop-cultivation patterns and/or agricultural productivity and resulting economic effects on agricultural sector. The other investigates the impacts of sea-level rise on land use/coverage and resulting economic damages in terms of land-value loss where the effects on agriculture is treated as one sector among others. To enhance integrated assessment, we suggest that 1) scenarios need to incorporate the effects of climate change and sea-level rise simultaneously, 2) scope of the assessment needs to be extended to include ecosystem services as well as crop production, 3) social and cultural aspects need to be considered in addition to economic analysis, and 4) synthesis of the outcomes from each step should be able to combine quantitative as well as qualitative information.
