Seismic fragility curves play a crucial role in assessing potential seismic losses and predicting structural damage caused by earthquakes. This study compares non-sampling-based methods of seismic fragility curve derivation, particularly the probabilistic seismic demand model (PSDM) and finite element reliability analysis (FERA), both of which require employing sophisticated finite element analysis to evaluate and predict structural damage caused by earthquakes. In this study, a three-dimensional finite element model of API 5L X65, a buried gas pipeline widely used in Korea, is constructed to derive seismic fragility curves. Its seismic vulnerability is assessed using nonlinear time-history analysis. PSDM and a FERA are employed to derive seismic fragility curves for comparison purposes, and the results are verified through a comparison with those from the Monte Carlo Simulation (MCS). It is observed that the fragility curves obtained from PSDM are relatively conservative, which is attributed to the assumption introduced to consider the uncertainty factors. In addition, this study provides a comprehensive comparison of seismic fragility curve derivation methods based on sophisticated finite element analysis, which may contribute to developing more accurate and efficient seismic fragility analysis.

Comparison of results from two different methods of soil-structure dynamic interaction analysis is presented. Two methods include transfromed static and seismic response analyes. In seismic response analysis, the difference in result of total stress analysis relative to effective stress analysis is investigated.

본 연구는 상향 사회비교를 통해 발생 되는 긍정과 부정의 감정을 균형 있게 살펴보고 발생 된 감정의 결과가 SNS 이용자의 게시 행태에 미치는 영향을 탐구한다. 특히, 본 연구는 상향 사회비교가 SNS의 팔로워와 게시자의 SNS 이용행태에 미치는 영향력과 팔로워가 다시 게시자가 되는 소셜 네트워크 순환의 구조적 원리를 체계적으로 규명해보고자 한다. 분석 결과, 상호작용 성향의 팔로워는 부정적인 상향 사회비교와 긍정적인 상향 사회비교를 하였으며, 부정적인 상향 사회비교는 독립 성향 게시를 감소시키는 것으로 나타났다. 하지만, 긍정적인 상향 사회비교는 독립 성향 게시와 상호작용 성향 게시 모두를 증가시키는 것으로 나타났다. 이러한 본 연구의 결과는 SNS에서 사회비교 이론이 부정적 상향 비교에만 치우쳐져 있던 선행 연구의 결과를 긍정적 상향 비교까지 확장 시켰다는 데 의의가 있다. 더불어, 본 연구는 SNS 플랫폼 운영자들에게 SNS 이용자들이 다른 플랫폼으로 이탈하지 않는 방안에 대한 실무적 전략을 제시하였다.

본 연구는 컴퓨터 문헌 분석 기법을 활용하여 <토끼전> '어족회의' 대목의 계열과 계통을 밝히는 데에 목적을 둔다. 우선 각 단락의 이본 유형을 인코딩하여 코퍼스를 구축하고, 이를 바탕으로 해밍 거리를 이용하여 각 이본 간의 거리 행렬을 산출하였다. 그다음 산출된 거리 행렬을 다차원 척도법, 계층적 군집 분석을 적용하여 이본의 군집 양상을 시각화하여, 기존에 토끼전 전체 단락을 대상으로 한 군집 분석 연구와 비교하여 '어족회의' 대목의 계열과 계통 특징을 살펴보았다. 그 결과 토끼전 전체 단락을 대상으로 한 군집 분석이 6개의 계열을 이루고 있는 것과는 달리, '어족회의' 대목은 5개의 계열을 이루고 있다는 점과 몇몇 이본의 계열 출입이 있다는 점을 확인할 수 있었다. 본 연구의 성과는 계산에 의한 객관적이고 실증적인 방법으로 이본 간의 상대적 거리 측정하고 계통 분류를 했다는 점과 토끼전 전체를 내용을 대상으로 한 계열 분석과 대비하여 어족회의 대목 계열의 특징을 밝혔다는 데에 있다.

Most of CAE analyses for injection molding have been based on the Mele Shaw's approximation: two-dimensional flow analysis. in some cases, that approximation causes significant errors due to loss of the geometrical information as well as simplification of the flow characteristics in the thickness direction. Although injection molding analysis software using three-dimensional solid elements has been developed recently, such as Moldflow Flow3D, it does not contain a deformation analysis function yet. The present work covers three-dimensional deformation analysis or injection molded plastic parts using solid elements. A numerical scheme for deformation analysis has bun proposed from the results of injection molding analysis using Moldflow Flow3D. The accuracy of the proposed approach has been verified through a numerical analysis of rectangular plates with various thicknesses in comparison with the classical shell-based approach. In addition, the reliability of the approach has also been proved through an industrial example. an optical plastic lens, in comparison of real experiments.

This paper deals with a comparison between Taguchi's accumulation analysis method and Nair test on the ordered categorical data from an industrial experiment for quality improvement. a result of Taguchi's accumulation analysis method is shown to have reasonable power for detecting location effects, while Nair test identifies the location and dispersion effects separately, Accordingly, Taguchi's accumulation analysis needs to develop methods for detecting dispersion effects as well as location effects. In addition this paper rewmmends models for analyzing ordered categorical data, for examples, the cumulative legit model, mean response model etc Successively simple, reasonable methods should be introduced more likely to be used by the practitioners.

A total of 40 Korean and Japanese rice varieties were evaluated for their main chemical components, physical properties, cooking quality, pasting properties, and instrumental measurements. Based on their quality evaluations, it was concluded that Korean and Japanese rice varieties were not significantly different in the basic components of NIR (Near Infra Red) data and the chemical analysis from the uncooked brown and milled rices. Korean rice had a little bit higher protein and amylose contents but much lower fat acidity than those of Japanese rice from the chemical analysis. From all the data of three different kinds of NIR methods, Korean and Japanese milled rice were very similar except the taste score. Japanese rice showed a slightly higher taste score, a little bit higher lightness and whiteness, but lower yellowness and redness than Korean one. From all those data of NIR and the chemical analysis, Korean and Japanese rices had very similar components except the fat content.

The cluster analysis on the distribution of epiphytic lichens on the north, south, east and west slope of Mt. Hanra was carried out by three methods, sum of square algorithm (SSA), prinicipal component analysis (PCA) and multidimensional scaling method(MDS). Analysis of concentration (AOC) was used for the comparison between the lichen communities of north and south slope. The lichen species was identified 35 species by Hale and Culberson technique. The classification of sites by SSA method was divided into two areas in four slopes, and that of species by SSA, PCA and MDS methods was classified into three clusters in east slope, four clusters in south and west slope, and there clusters in north slope. The comparison between north and south slope of the distribution of lichens indicates that loight elevation of north slope (NH; 1600m~1900m) was similar to that of relative low elevation of south slope (SL; 1000m~1300m). The genus lichen, Anaptychia, Parmelia, Lobaria and peltigera was found as the dominant genus in both slopes.

One of the activities to improve software quality in ISO 26262 is to apply the design principles for software unit design and implementation mentioned in ISO 26262-6, including the evaluation activity. Before evaluation activity, the tool is compared and selected for evaluation. Because the results of the tool a company selected might have an effect on product quality. In this paper, we suggest the method to compare industrial static analysis tools with some of "MISRA C : 2004 Exemplar Suite" and all lessons learned from comparing tools are described. The result on comparison shows that we just couldn't rely on a result of Static Analysis Tool and need to have another appropriate processes and guidelines to evaluate a software.
