In this research, we explore whether mere exposure to external cues with vertical progress (e.g., moving upward or moving downward) can influence individuals' persistence to complete focal tasks. Drawing on the theory of embodied cognition, we propose that, a moving-upward (vs. downward) cue activates the abstract concept of difficulty, which is associated with the physical experience of climbing uphill (vs. downhill). Due to this association between moving uphill and difficulty, merely exposing individuals to the moving-upward cue can induce greater feeling of difficulty and this greater difficulty, in turn, reduce individuals' persistence, compared to exposing individuals to the moving-downward cue. Across three studies, we find supporting evidence for the effect of the external cues with vertical progress on individuals' performance both in physical tasks and in a cognitive task.

In-situ soil remediation mechanism through the vertical drains (VDs) is analyzed with numerical model as the error and complementary error function. Results from in-situ test and analysis indicate that the contaminant concentration ratio as initial one ( C/$C_0$) increases as the radius ratio ( r/R) increases from the injection well, and also increases as the depth ratio ( z/ H) increases from the top of contaminated area. The elapse time needed to attain $50\%$ and $90\%$ clean up level ($ t_{50},\;t_{90}$) increases as the radius ratio ( r/R) and the depth ratio ( z/ H) increase. As above results, the procedure of soil flushing in contaminated area using vertical drains makes progress from the top of injection well to the bottom of extraction well.

With the progress of optical communication technology recently, the development of micro actuator using MEMS technology has been made for optical switching. The actuation types are various; electrostatic, electromagnetic, and electrostatic +electromagnetic etc. Among them, the electrostatic type is the most popular because of the relative ease of fabrication, integration and shielding as well as low power consumption. However, it needs a high voltage to generate a larger driving force. To overcome this problem, we proposed a new type of electrostatic actuator with an extra vertical electrode in addition to the horizontal one. The vertical electrode also lays a role of making the stable angular rotation as a stopper. From the theoretical analysis and experiment, we find the actuation voltage can be reduced up to 50 % of that of the conventional one.

대두 갈색무늬병의 진전은 한 식물체에서 상위엽으로의 진전속도(수직감염율 : vertical progress)과 밀접한 관계가 있다. 실제로 포장에서의 갈색무늬병 진전은 주로 하위엽에서 발병하기 시작하여 상위엽에 비하여 이병정도가 높은 것이 보통이다. 이러한 현상의 원인을 구명하기 위하여 수행한 본 실험에서 갈색무늬병의 감염율은 잎의 성숙도와 정의 상관을 보였으며 이러한 유엽저항성은 접종원의 분포와는 무관한 것으로 보였다. 또 상위엽의 엽표면일출액 (leaf diffusate)은 병원균 포자발아 및 관계신장의 억제 정도가 하위엽의 일출액에 비하여 높았으며 이러한 경향은 저항성품종에서 더욱 현저하여 엽일출액의 어떤 발아억제물질이 갈색무늬병의 유엽저항성에 관여하는 것으로 추정되었다.

The Reduced Vertical Separation Minimum (RVSM), which is the reduced minimum from 2,000 ft to 1,000 ft at flight levels (FL) between 290 and FL410 inclusive, was implemented in 30 September 2005 within the Japanese domestic airspace. Prior to the implementation, safety assessment for the airspace in assumed RVSM environments was carried out. Some model parameter values of collision risk model were estimated using flight plan (progress) data and radar data. An estimate of vertical collision risk including operational risk was calculated using these together with given parameter values. The results obtained from this analysis are as follows. (1) Contribution of the vertical collision risk for the crossing routes is about 9 percents of the total technical risk. (2) The estimate of the collision risk is $4.1{\times}10^{-9}$ [fatal accidents / flight hour] and the value is smaller than a maximum allowable level of collision risk, i.e. $5{\times}10^{-9}$ [fatal accidents / flight hour], called the Target Level of Safety.

최근 PC 공법을 도입하려는 시도가 많이 이루어지고 있다. 그러나 PC 벽체에 대한 연구는 개발의 어려움이 있어 상대적으로 더디게 발전되어 왔다. 본 연구에서는 PC벽체의 기존의 접합부의 시공성 및 구조성능을 개선하기 위하여 수직접합부의 개선안을 개발하였고, 이에 대한 구조성능평가를 진행하였다. 제안된 PC벽체의 수직접합부 구조적인 성능을 검증하기 위하여 반복적인 횡하중 재하시험을 진행한 결과, 기존의 일체형 PC벽체와 동등이상의 내진성능을 발휘하는 것으로 나타나 향후 구조물의 주요 횡력저항요소로 충분히 적용가능할 것으로 판단된다.

인식 주체는 자신의 경험을 바탕으로 주어진 대상에 구조를 부여하여 대상을 구조로 인식하려고 한다. 주어진 문제 맥락 속에서 주체가 대상에 부여할 수 있는 구조는 횡적, 종적으로 다양하다. 구조의 횡적 다양성의 측면에서, 한 대상 속에서 다양한 구조를 발견하는 데 초점을 맞춘 문제해결 활동은 다양한 전략 사용에 중점을 둔 문제해결 교육의 보완이 될 수 있다 또, 도형 패턴 과제에서 일반식의 발견은 문제해결의 종착점이 아닌 새로운 구조 탐구의 시발점으로 여겨져야 한다. 구조의 종적 다양성의 측면에서, 교사는 학생이 보는 구조와 교사가 보는 구조가 다를 가능성에 유의하면서, 구조의 종적 다양성에 기초하여 아동이 진보의 경험을 할 수 있도록 지도하는 방안을 모색할 필요가 있다.

In the present investigation, experiments on the melting of a phase change material were performed to research heat transfer phenomena generated by means of conduction and natural convection in the vertical tube at inward melting. The phase change material used in the experiments is 99 percent pure n-Docosane paraffin which is measured melting temperature of $42.5^{\circ}C$, latent heat of 37.5 cal/g, heat conductivity of $0.1505W/m^{\circ}C$. Experiments were performed both in the no-subcooling which is initiating it at melting temperature of phase change material, and in the subcooling which means to initiate it under melting temperature of phase change material, in order to compare and investigate the horizontal temperature history, vertical temperature history, ratio of melting and melted mass, figure of the melting front in the vertical tube. In the experimental results, heat transfer from tube wall to phase change material were due to conduction at early stage and due to natural convection with the passage of time, and then occurred melting downward from surface by volumetric expansion. Natural convection affects temperature distribution in the tube, ratio of melting and melted mass, figure of the melting front and then progress rapidly in case of nosubcooling compared to subcooling.
