This paper describes the dynamic fracture behavior of brittle materials under impact loading by using INSAMCR program with instrumented charpy test machine. To calculate the Dynamic Stress Intensity Factor The finite element analysis methods program, INSAMCR, was used. Dynamic fracture characteristic was researched to verify a relationship between Dynamic Stress Intensity Factor and crack tip propagation velocity in WC-6%Co. The relationship between Dynamic Stress Intensity Factor and crack tip velocity revealed typical .GAMMA. shape. INSAMCR was run to verify experimental results in WC-6%Co and shows a good coincidence.

This study examines the relationship between the concern about well-being lifestyle and the perceived image of Hanji fiber. A survey was conducted among male and female consumers aged 20 and over in Jeonju and Daejon from January 4th to 11th, 2008. A total of 168 responses were analyzed by using descriptive statistics, factor analysis, and ANOVA via the SPSS ver. 12. As a result, four factors were determined in the concern for a well-being lifestyle; product consumption, enjoying culture, using therapy and managing the household. The perceived image of Hanji fiber were classified into four elements; traditional, high-quality, functional and popular images. Among the factors of the concern for a well-being lifestyle and the perceived image of Hanji fibers, a partial relationship was observed. There is a positive relationship, especially between the product consumption factor of a well-being lifestyle and the high-quality and functional image of Hanji fiber. Also, there was a positive relationship between the factor of managing the household and the traditional image of Hanji fiber. However, the therapy interest factor of a well-being lifestyle was negatively related to the traditional image of Hanji fiber.

The purpose of this study was to investigate the influence of consumer-internet brand relationship on consumer's satisfaction and loyalty. In order to establish structural equation model, previous studies about consumer-brand relationship, consumer's satisfaction and loyalty were investigated. The survey was limited to the respondents over 20 years old living in Seoul and other metropolitan areas who had purchased fashion products in internet shopping mall. Questionnaires were collected from February 1, 2012 to February 12, 2012 and 562 useful data were analyzed by descriptive statistics, exploratory factor analysis, confirmatory factor analysis, reliability analysis, and Pearson's correlation analysis, using Amos 19. The results of verifying the hypotheses were as follows: First, consumer-internet brand relationship was classified into two dimensions including 'emotional affection' and 'cognitive trust'. Second, both 'emotional affection' and 'cognitive trust' had a positive effect on consumer's satisfaction. Third, 'emotional affection' had a positive effect on consumer's loyalty, but 'cognitive trust' did not affect consumer's loyalty directly. Finally consumer's satisfaction had a significant effect on consumer's loyalty. It was suggested that consumer-internet brand relationship could be an important factor to form brand equity. Therefore, internet shopping mall marketer should establish a strategy that can help customers make a strong relationship with their internet shopping mall.

본 연구의 목적은 학생들의 과학관련 진로선택과정의 인과요인을 분석하는 것이다. 학생들의 과학관련 진로선택과정에 대한 인과관계를 구조방정식모형을 구성하여 분석하였다. 개인적 요인, 교육적 요인, 사회적 요인이 과학 진로 희망에 직접 효과를 주고 과학 진로 희망은 과학 진로 선택에 직접 영향을 준다는 연구 가설에 가장 적합한 모형에 의하면, 과학 진로 선택에 과학 진로희망이 0.95의 직접효과를 주며, 개인적 요인이 0.75, 교육적 요인이 0.46, 사회적 요인이 0.11의 간접 효과를 주며 이들 효과가 그대로 총 효과를 주는 것으로 나타났다. 과학진로희망에는 개인적 요인이 0.79의 직접효과 및 총 효과를 주며, 교육적 요인이 -0.21의 직접효과와 0.69의 간접효과를 합하여 0.48의 총 효과를 주고, 사회적 요인이 0.12의 직접효과 및 총 효과를 주는 것으로 나타났다. 한편, 교육적 요인이 사회적 요인에 0.72, 교육적 요인이 개인적 요인에 0.77의 직접 효과 및 총 효과를 주는 것으로 나타났다. 초중고 학생 및 남학생과 여학생으로 대상을 달리하여 인과 효과를 비교 분석한 결과, 학교급별로는 전체 학생들과 경향성이 같고, 각 요인들의 영향 정도만 차이가 있었으나, 성별로는 남녀 학생의 대비가 두드러졌다. 남학생은 사회적 요인의 총 효과가 가장 크고, 그 다음이 개인적 요인, 그 다음이 교육적 요인의 순서로 나타난 데 비해, 여학생은 개인적 요인의 효과가 가장 크고 나머지 두 요인의 효과는 그리 크지 않았으며, 사회적 요인은 음으로 나타났다. 이러한 대상별 분석 결과로부터 각 대상의 과학진로선택과정의 인과관계를 고려한 과학진로교육의 방향에 대한 시사점들을 논의하였다.

쏘일네일 공법은 일반적으로 한계평형해석법을 토대로 검토한 사면안정해석결과를 이용하여 설계기준안전율 이상을 만족하면 안정한 것으로 판단하여 설계하고 있다. 그러나 쏘일네일의 길이가 짧은 경우 설계기준안전율을 만족하고도 발생변위가 과다하여 사용상에 문제가 발생하는 경우가 있다. 본 연구는 대형파괴재하시험결과에 의한 재하하중-안전율 및 재하하중-발생변위비와의 관계를 분석하여 쏘일네일 보강벽체의 안전율-발생변위비와의 상관관계를 분석하였으며, 분석결과 쏘일네일 보강벽체의 사용한계상태에 해당하는 발생 변위비 0.3% 이내를 만족하기 위해서는 한계평형해석에 의한 안전율이 최소 1.35 이상을 확보하여야 할 것으로 평가되었다. 또한 한계평형해석결과 최소 안전율 1.35 이상을 만족하여도 지반의 전단강도가 작거나 벽체높이가 높을 경우 사용한계상태에 해당하는 발생 변위비 0.3% 이내를 만족하지 못하는 경우가 있어 수치해석을 통한 발생변위 검토가 필요할 것으로 판단된다.

In optmizing cutting condition for face milling operation, tool wear is an important maching factor. For the purpose of establishing the relationship between various maching factor and tool wear, cutting tests have been performed. As a result, hardness and chemical composition of workpiece material, chemical compositition and grain size of cutting tool and cutting speed have been selected as machining factor. In addition, relationship between feed rate and workpiece hardness has been observed. Prior to utilizing cutting condition recommended by 'Machining Data Hardbook(MDH)' as a Knowledge base, an analysis for the validity has been provided. Based on this analysis, tool life criteria applied by MDH has been modifiied. Finaly, using MDH recommended data for neural network trainning, we can compensate the result form the trained neural network for optimizing cutting condition for some given workpice and cutting tool.
