In our study, the experiment tried to find the optimum cutting conditions and method by observing the cutting force working at ball end-mill varying axial depth and radial depth for upward cutting and downward cutting along the decline. As a result of the experiment, the cutting was more unstable in downward cutting than in upward cutting and also in the case of axial depth than in radial depth, which resulted from the fact that the cases of downward cutting and of radial depth had a relatively wider contact surface than that of upward cutting and of axial depth and approached the edge at extreme point of a tool more closely rather than a side blade, and the cutting force had a tendency to be reduced as the inclined angle increased.

Hydrogen Adsorption on sp2-Bonded Carbon Structures: Ab-initio Study

권영균 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.4

Using ab-initio density functional theory, we investigate both molecular and atomic hydrogen adsorption properties for sp2-bonded carbon materials, such as graphene, fullerenes, and nanotubes,and their modified structures. Weak molecular hydrogen binding depends on different binding sites and hydrogen orientations. The energy barrier of the drift motion of a hydrogen molecule on the surface of graphitic materials is estimated to be small. We find that some modifications of the sp2-bonding characters of graphitic materials, resulting from structural deformation or chemical doping,tend to enhance molecular hydrogen binding, and thus may increase the desorption temperature. Atomic hydrogen binds chemically or relatively strongly to the host carbon materials, resulting in a local modification of sp2 carbon to sp3 carbon. However, such strong atomic bonds easily breaks in the presence of unbound atomic hydrogen to form more favorable molecular hydrogen.

본 연구는 무용전공자의 자기관리와 신체적 자기지각 및 공연자신감의 이론적 구조모형을 가설로 설정하고 이를 검증하는데 목적이 있었다. 총 419명의 대학교 무용전공자를 대상으로 무용수 자기관리와 신체적 자기지각, 공연자신감 질문지를 사용하여 탐색적 요인분석과 확인적 요인분석을 통한 측정도구의 신뢰도 타당도 검증, 상관분석 및 구조모형 검증을 실시하여 몇 가지 의미 있는 결과를 산출하였다. 첫째, 탐색적 요인분석에서 추출한 요인을 바탕으로 측정모형을 구축하고 이를 검증한 결과 세 측정모형 모두 전반적 적합도 지수가 기준치를 상회하거나 승인할 만 하였다. 둘째, 상관분석을 실시한 결과 자기관리, 신체적 자기지각, 공연자신감 간에 의미 있는 정적 상관을 나타내고 있었다. 셋째, 가설화된 구조모형을 검증한 결과 전반적 적합도 지수가 높게 나타났다(x²/df=3.692, GFI=.919, CFI=.914, RMR=.035). 마지막으로 구조모형의 인과효과를 분석한 결과 무용수 자기관리는 공연자신감에 직접적으로 정적 영향을 미칠 뿐만 아니라 신체적 자기지각을 통해 공연자신감에 정적인 영향을 미치는 것으로 나타났다. 이러한 결과를 토대로 이론적, 실제적 관점에서 논의하였다. The purpose of this study is to verify the validity of the structural model concerning self-management, physical self-perception, and performance confidence of the college dance majors. Total 419 persons participated in this study. The validities of questionnaires were verified by the exploratory and the confirmatory factor analyses, and the correlation coefficient and the structural model analyses were followed. First, all three measurement tools were verified to be acceptable. Secondly, three factors showed positive relationships. Next, overall acceptability of the hypothesized structural model was provided. Analyses of the causal relationships within the structural model showed that self-management had a meaningful influence on the physical self-perception, and performance confidence, and physical self-perception had a meaningful influence on the performance confidence as an inter-mediatory variable. Finally, as a part of discussion, possible theoretical explanation of these results were introduce, and inference of these influences among the variables were suggested for the practical applications.

Purpose: The purpose of this study is to investigate the primary factors that affect consumers e-Trade purchase intention. In detail, we focused on the effect of the anxiety(fear) related to death which was caused by Internet news prior to consumers’ e-trade purchase on their purchase intention based on TMT(Terror Management Theory). Composition/Logic: This study started with background and presented purpose of the study In chapters 1 and 2. We examined previous studies related to TMT. The ‘Purchase Intention’. in chapter 3, we proposed the research model and Hypothesis based on the theoretical background and showed the measurement tool. The empirical analyses was conducted in chapter 4. In chapter 5, we summarized the findings based on statistical analyses and discussed conclusions. The chapter 5 summarized the findings and discussed implications and future research. Findings: The results of the study showed that 'fear of dying process' had a greater positive effect on utilitarian product purchase intention as compared to hedonic product purchase intention. However, the 'fear of unknown’ affected positively on hedonic product purchase intention. The consumer’s self-construal acted as a moderator, between the causal pathway of the fear of dying process and the purchase intention. The 'fear of unknown' was not moderated. Originality/Value: Based on this study, the anxiety conditions such as world-wide terrorism and natural disasters should be take into considerations in understanding consumers’ anxiety reactions caused by negative events. This can help to establish marketing strategies for the e-trade and market place under conditions.
