Measuring market fear is an important way of understanding fundamental economic phenomena related to financial crises. There have been several approaches to measure market fear or panic level in a financial market. Recently, herd behavior has gained its popularity as important economic phenomena explaining the fear in the financial market. In this paper, we investigate herd behavior in global stock markets with a focus on intercontinental comparison. While various risk measures are available for the detection of herd behavior in the market, we use the standardized herd behavior index in Dhaene et al. (Insurance: Mathematics and Economics, 50, 357-370, 2012b) and Lee and Ahn (Dependence Modeling, 5, 316-329, 2017) for the comparison of herd behaviors in global stock markets. A global stock market data from Morgan Stanley Capital International is used to study herd behavior especially during periods of financial crises.

The purpose of this research is to determine the influence of affectionate child-rearing behavior on children's self esteem. The sample group was composed of 200 forth and sixth grade elementary school students. The statistics used for this data were frequency, percentile, averages, standard deviation, Cronbach's alpha, t-test, Pearson's correlation, and stepwise multiple regression analysis. The major findings of the research were as follows: First, the scores of affectionate child-rearing behavior(3.60), global self-worth(3.58), social acceptance(3.46) and behavior conduct(3.28) were higher than the mean scores. On the contrary the scores of cognitive ability(2.95), physical ability(2.94) and physical appearance(2.85) were lower than the mean scores. Second, there were significant differences in cognitive ability based on gender(p＜.01) and global self-worth based on grade(p<.05). Third, the influence of affectionate child-rearing behavior on children's self esteem was found to be significant due to the sub-areas of self-esteem. Affectionate child-rearing behavior affects all sub-areas of self-esteem. Affectionate child-rearing behavior affects cognitive ability(p<.001), physical ability(p＜.01), physical appearance(p＜.01), social acceptance(p＜.001), behavior conduct(p＜.01) and global self-worth(p＜.001). In addition, gender(p＜.01) affects cognitive ability and grade(p＜.05) affects global self-worth.

The main purpose of this study was to examine relative effects on safety behaviors between global feedback and specific feedback at a construction site. Participants were 30 full-time workers at a construction site. Five safety related behaviors were identified as critical behaviors. An ABCB within-group design was adopted. After baseline (A), participants received global feedback on their average percentage of all five target safety behaviors (B). In the next phase, participants received specific feedback on the percentages of individual target behaviors (C). In the final phase, the global feedback condition was reintroduced (B). Results showed that both global feedback and specific feedback were effective in increasing the frequencies of safety behaviors and there were no differences in the effectiveness between the two types of feedbacks.

Global attractor is a basic concept to study the long-time behavior of solutions of the various equations. This paper is investigated with the existence of a global attractor for the beam equation $$u_{tt}+{\Delta}^2u-{\nabla}{\cdot}\{{\sigma}({\mid}{\nabla}u{\mid}^2){\nabla}u\}+f(u)+a(x)g(u_t)=h,$$ using multipliers technique and Nakao's Lemma.

세계 경제가 글로벌화 됨에 따라 개인이나 국가의 경쟁력 제고를 위한 인재 양성 요구가 높아지고 있다. 해외 유학은 양질의 교육에 접근하고 현지 시장, 국제 시장을 더 가까이에서 접할 수 있는 교육 방법 중 하나로 여겨지고 있다. 이러한 사회적 분위기에서 본 연구는 유학생들을 대상으로 글로벌 역량과 예술적 역량 요인들을 정의하고, 이 역량들이 창업의도에 미치는 영향과 영향관계에서의 네트워킹 행동의 매개효과, 사회적 지지의 조절 효과에 대해 규명하고자 하였다. 본 연구의 분석 결과는 다음과 같다. 첫번째, 지식, 기술, 태도 등 글로벌 역량의 3가지 하위요인들은 네트워킹 행동에 정(+)의 영향을 미친다. 두번째, 표현, 창조성, 미디어 등 예술적 역량의 3가지 하위요인도 네트워킹 행동에 정(+)의 영향을 미치고 있었다. 세번째, 네트워킹 행동은 창업 의도에 정(+)의 영향을 미치는 것으로 나타났다. 네번째, 사회적 지지는 네트워킹 행동과 창업 의도 사이에서 조절효과를 가지는 것으로 나타났다. 다섯번째, 네트워킹 행동은 글로벌 역량과 창업 의도 사이에서 대한 매개효과가 있었다. 본 연구는 새로운 교육 환경과 사회문화 환경에 적응하고 있는 유학생들을 대상으로 연구함으로써 유학생들의 네트워킹 행동이 창업의도에 긍정적인 역할을 한다는 점을 검증한 데 의의가 있다고 할 수 있다.

The objective of this study is to develop a damage model based on damage mechanics that can be used to analyze the mechanical behavior of structures with defects and the global behavior of damaged structures. A modified second order damage tensor that can be applied to finite element analysis is used to reflect the effect of damage. The damage stress computed from the effective stress is considered as an additional loading term acting on nodes and can represent the effect of crack surface. The accuracy of the proposed algorithm is verified by comparing the analysis results with the experimental data from other studies and the analysis results based on transverse isotropic theory. The developed damage model is applied to the analyses of structures with cracks under linear elastic condition. Numerical results show that the developed model can effectively analyze the global behavior of damaged structures.

Considered here is the first initial boundary value problem for the two-dimensional g-Navier-Stokes equations in bounded domains. We first study the long-time behavior of strong solutions to the problem in term of the existence of a global attractor and global stability of a unique stationary solution. Then we study the long-time finite dimensional approximation of the strong solutions.

It appears our global society and economy are here to stay, despite current events. Mass communications including The Internet, increased world travel, and more and more consumers developing the ability to afford consumer goods, are all helping to bring world cultures closer together. Indeed, the world is rapidly changing and the fashion consumer, is especially affected. Despite the increased commonalities of peoples of the world, culture is a concept crucial to the understanding of consumer behavior. Marketers must understand the values, ethics, and customs of societies around the world to be successful in the global marketplace.

The aim of this paper is to prove the existence of the global attractor of the Cauchy problem for a semilinear degenerate hyperbolic equation involving strongly degenerate elliptic differential operators. The attractor is characterized as the unstable manifold of the set of stationary points, due to the existence of a Lyapunov functional.
