In this study, the numerical simulations of the spray characteristics within the combustion chamber of direct injection diesel engine were performed to examine the applicability of turbulence model. The turbulence models used were the RNG model and the modified ?? model which included the compressiblity effect due to the compression/expansion of the piston. The spray model was based on the stochastic particle technique and accounted for droplet breakup, collision and coalescence, evaporation and the turbulence interactions with the gas phase. The finite volume method was employed to discretize the governing equation of the gas phase and Euler implicit algorithm was utilized to discretize the Lagrangian equation of the liquid phase. The PISO algorithm which strengthened the velocity-pressure coupling was used and the SIP method was used as a matrix solver. The predicted results in the quiescent condition showed reasonable trends comparing with experimental data. The application of the RNG model seemed to have some potential for the simulations of the spray characteristics over the ?? model.

We are going to make clear three things through the examination of the subject of this study. The first thing is to verify whether perceived usefulness and ease of use of usage have positive effects on trust and satisfaction which determine the loyalty of a shopping mall. The second is to find out the effect of perceived usefulness and ease of use of using internet shopping mall on shopping mall's loyalty through variable intermediation of trust and satisfaction. The third is to emphasize the importance of perceived usefulness and ease of use of using a shopping mall web sites and carrying out a through analyzing path that usefulness and ease of use are intermediated by trust and satisfaction to loyalty. We made a poll to people who had ever used internet shopping mall and got information. The results are below. The easer internet shopping mall users feel when using shopping mall sites, the more they feel them useful. Perceived usefulness and ease of use of usage have positive effects on trust and satisfaction which are major preceding factors of internet shopping mall loyalty. The perceived ease of use, trust, and satisfaction intermediate between the perceived ease of use and shopping mall's loyalty while users are accepting internet shopping mall. And trust and satisfaction intermediate between the perceived usefulness and shopping mall's loyalty. These results show that the degree of usefulness and feeling easiness in using shopping mall of users should be considered seriously. The only easiness of shopping mall doesn't create shopping mall's loyalty, but, it's created when users acknowledge the usefulness, trust, and satisfy.

동기식 대역확산 다중출입 통신의 오류 확률을 특성함수를 이용하여 구했으며 변조 방식으로는 PSK가 사용되었다. 채널용량을 이용하여 성능을 분석하였고 신뢰성 있는 통신을 위한 최소 비트 신호대 잡음비를 계산하였다. The error probability for coherent frequency-hopped spread-spectrum multiple-access communications is computed by using characteristic function method. We employ PSK as a modulation scheme. The channel capacity is performance measure and the minimum bit signal-to-noise ratio for reliable communications is obtained.

There are many researches on the positive effect of the mindfulness. However, the researches on the factors of improving mindfulness are hard to be found. This study is trying to find how positive factors like self-esteem affect mindfulness. 775 college students were subjects of completed the K-MAAS, Self-Esteem Scale, Happiness Quotient, Spiritual Well-Being Scale. It revealed that Self-Esteem, Happiness, and Spiritual Well-Being were positively related to the degree of K-MAAS. Regression revealed that Self-Esteem positively is related to the mindfulness. The results of this study shows that it needs to improve the self-esteem for the activation of mindfulness 마음챙김이 개인에게 미치는 긍정적 영향에 관한 연구들이 많이 진행되고 있다. 그러나 마음챙김을 증진시키는 요인이 무엇인지에 대해서 알아본 연구는 거의 찾아보기가 어렵다. 본 연구는 자아존중감과 같은 긍정적 요인이 마음챙김에 어떤 영향을 미치는 지를 알아본 것이다. 대학생 775명을 대상으로 마음챙김척도와 자아존중감척도, 행복척도, 영적 안녕 척도 등을 실시하여 마음챙김에 미치는 영향을 알아보았다. 연구결과, 자아존중감과 행복, 영적 안녕 등은 마음챙김 수준과 정적 상관을 가지고 있었다. 회귀분석결과는 자아존중감이 마음챙김 수준에 유의한 영향을 미치고 있었다. 본 연구결과는 마음챙김의 활성화를 위해서는 자아존중감을 향상시킬 필요가 있음을 시사한다.

The roles of eunuches in the era of strong dynasty should be limited to serve the emperor in a hermit land. According to the advance of state building and the strength of the autocrats, the political wants and needs was the causes of the spreads and enlargement of eunuches’ forces and became the cause of political intervention of eunuches’. This paper analyzes the structural causes of eunuches politics in the old Chinese Dynasty and in the reign of King Yonsan in Joseon Dynasty. The structural causes of eunuches politics are tried to explain the patterns of political dynamics among three groups, that is, autocrat, royal relative by marriage and political party strifes. This three-folded political dynamics are analyzed within three categories, that is. the relationship between autocrat and eunuch, the relationship between eunuch and royal relative by marriage, and the relationship between eunuch and political party strifes. This article could be the beginning of and the implications of the desired roles and mind-set of staffs’ in modern organizations.
