  • In this paper, 3-dimensional fracture phenomena in the local area near a through notch tip located between the surface and the canter were investigated by using embedded dyeing grids with the pitch of $50.8{\mu}$. It was confirmed that displacement V and square root of distance from notch tip $y^{1/2}$ are not proportional in the local area of $\sqrt{{\mid}y{\mid}}\;<\;0.3mm^{1/2}$ and the maximum shea strain ${\varepsilon}_{xymax}$ near a notch tip occurred at the curvature beginning point of the notch curve. It was also noted that the maximum strain ${\varepsilon}_{xymax}$ in the thickness direction occurred at the interior, where the ratio of the distance measured from surface to the half of thickness of specimen is 0.3.

  • This paper aims to provide an account for the English anaphors under the framework of the recent development of minimalism (Chomsky 1999, 2001). I propose that the anaphor has the uninterpretable [a] feature. The Agree operation erases the [a] feature by feature match. Once the [a] is deleted, the derivation converges, providing a proper interpretation of the anaphor. When there is no matching phi-features, the [a] cannot be eliminated, inducing the derivation to crash. The Agree operation can account for not only the typical local binding cases in English but the apparent long-distance binding cases in the picture-DP and expletive constructions. Consequently, the traditional concept of the binding domain and dichotomy between local and long-distance types are abandoned in favor of the analysis under the framework of minimalism. The minimalist accounts thus maximally simplifies the binding principles, using the general operation Agree only.

  • For a similar price signal to local consumer, a regional clustering is important that can transfer a equal sign to the bus which has each different price on the basis of bus. If you take LMP and local information this method into consideration at the same time, and you give weight on neither one side, buses on a borderline can move on arbitrary. For solving this problem, in this paper will propose a clustering method to have applied new concept called 'electric distance'.

  • In this paper, we propose a hierarchical method for segmenting a given 3D mesh, which hierarchically clusters sharp vertices of the mesh using the metric of geodesic distance among them. Sharp vertices are extracted from the mesh by analyzing convexity that reflects global geometry. As well as speeding up the computing time, the sharp vertices of this kind avoid the problem of local optima that may occur when feature points are extracted by analyzing the convexity that reflects local geometry. For obtaining more effective results, the sharp vertices are categorized according to the priority from the viewpoint of cognitive science, and the reasonable number of clusters is automatically determined by analyzing the geometric features of the mesh.

  • Heat transfer characteristics of a two-dimensional oblique impinging jet were experimentally investigated. The local heat transfer coefficients were measured by a thermochromic liquid crystal. The jet Reynolds number studied was varied from 10000 to 35000, the nozzle-to-plate distance(H/B) from 2 to 16, and the oblique angle($\alpha$) from $60^{\circ}$ to $90^{\circ}$. It was observed that the local Nusselt numbers in the minor flow region were larger than those in the major flow region at the same distance along the plate due to the higher levels in the turbulent intensity caused by more active mixing of the jet flow.

  • It is increasing scenery created as a result of pine wilt disease. The purpose of this study is to investigate the local resident's awareness against the scenery caused by pine wilt disease in their neighboring area, through the questionnaire investigation. The result showed that more than $40\%$ of the residents are not aware of such scenery in their local area, and about 30% of the residents did not know that those trees were dying. More than $40\%$ of the people do not know of the pine wilt disease as a general argument. Another question showed that the recognition of such scenery depends on the distance of the viewer. General residents don't worry about such scenery in the far distance in fact some of them think those are colored leaves. However, the nearer they see the trees, the higher they have negative feeling against it.

  • 네트워크 거리 (Network distance : 일반적으로 ping이나 traceroute 등으로 측정 가능한 round trip time 등 네트워크 상에서 패킷 전송 시간) 추정 기법은 인터넷상의 많은 응용프로그램들에서 유용하게 사용된다. 예를 들면 다수의 서버를 인터넷상에 설치하고자 하는 경우 사용자들 간의 네트워크 거리를 알고 있다면 서버와 사용자간의 왕복 전송 시간 (Round Trip Time)등을 최소화할 수 있도록 서버를 분산하여 설치하는 구성을 도출해 낼 수 있을 것이다. Peer to Peer 응용 프로그램들에서도 이 네트워크 거리 정보는 매우 유용하다. 기존에 존재하는 추정 기법들은 대부분 유클리드 공간 좌표 기반 기법들로서 유클리드 좌표 상의 거리가 실제 네트워크 거리와 유사하도록 유클리드 공간 좌표를 지정한다. 그러나 이런 방법들의 문제점은 인터넷 상의 네트워크 거리가 삼각 부등식을 만족하지 않는 경우가 존재하는 등 유클리드 공간의 기본적인 가정을 만족하지 못한다는데 있다. 이런 문제점 때문에 새로운 모델이 필요하고, 이 논문에서는 가상 토폴로지(Virtual Topology) 모델과 지역 조정 항 (Local Adjustment Term) 모델을 제시하고, 기본적인 성능 분석을 시도하였다.

  • The paper explores the relationship among the personnel characters, organizational formalization and organizational commitment in Korean firms in Shandong province of China. In this paper, the employee's personnel characters include the sexual, job, college graduate, collectivism(value attitude), Power distance(value attitude). The results of anaysis shows that College gratuate have negative effects on the organizational commitment, and the collectivism have positive effection on the affective commitment, the perception of organizational formalization have positive effects on the affective commitment. And, the perception of organizational formalization have moderlate effects among the job, college gratuate, collectivism, power distance with organizational commitment. Based on the these results, the paper described the theoretical and practical implications.

  • The local regression rate behavior of solid fuel in swirl injection hybrid rocket were studied. In generally, axial injection regression rate was tending to be decrease with axial distance, beyond which increased with increasing axial distance from the leading edge. On the other hand, swirl injection regression rate was high at the leading edge of the fuel and comparatively uniform regression rate at the downstream. Overall regression rate of swirl injection was increased about 54% for the overall regression rate of axial injection. Through this study, it was found that using swirl injector was useful in applying to the small sounding rocket.

  • Single-phase convection and partial nucleate boiling in free-surface and submerged jet impingements of subcooled water ejected through a 2-mm-diameter circular pipe nozzle were investigated by local measurements. Effects of jet velocity and nozzle-to-imping-ing surface distance as well as heat flux on distributions of wall temperature and heat transfer coefficients were considered. Incipience of boiling began from far downstream in contrast with the cases of the planar water jets of high Reynolds numbers. Heat flux increase and velocity decrease reduced the temperature difference between stagnation and far downstream regions with the increasing influence of boiling in partial boiling regime. The chance in nozzle-to-impinging surface distance from H/d=1 to 12 had a significant effect on heat transfer around the stagnation point of the submerged jet, but not for the free-surface jet. The submerged jet provided the lower cooling performance than the free-surface jet due to the entrainment of the pool fluid of which temperature increased.
