We reported pushing of colloidal particles by a moving isotropic-nematic phase boundary. Here, we report tailoring the structure of 3-dimensional networks formed by these particles by adjusting the rate of phase transition and by application of an electric field. The resulting networks affect the electro-optic performance of liquid crystal devices.

The modeling for the looper of a hot strip finishing mill to control the tension of the strip is presented. The looper is an arm pushing against the strip between stands in a tandem mill to keep the strip tension constant and to isolate the interactions of the adjacent stands. Tension is influenced by the difference in mass flow through the up stream and down-stream rolling stands. Tension is critical to strip quality, influencing width, gauge, and shape. This paper presents how looper angle and strip tension are controlled for a hot strip finishing mill.

This paper investigates the job-related low back pains (LBP) in Kuro industrial complex where the manufacturing industries are prevailing. The accident compensation claims during 1992 to 1994 were reviewed and total of 726 LBP claims were analyzed among 7920 compensation claims. A LBP database was constructed to analyze the LBP profiles of this area. The most frequent cause of LBPs was the manual materials handling related lifting, lowering, carrying, pushing or pulling(45.9%) and the second-most frequent cause was fall and slip (29.8%) and collision (7.9%) was the following cause of the LBP.

대부분의 다중 로봇(Multi-robots) 시스템은 환경적으로 단일로봇의 운용을 포함하지만, 수많은 연구가들은 제시된 임무를 완수하기 위하여 로봇 그룹이 협력함으로써 나타나는 잠재적 장점에 주목하게 되었다. 미지의 해성 탐사(Exploring), 물체 일기(Object pushing), 그리고 유독성 폐기물 첨소와 같은 작업을 수행하기 위해서는, 매우 복잡한 로봇을 사용하기 보다는 소형이며 간단한 다수의 로봇을 사용하는 것이 보다 효과적이다.

Using a simple random walk model, this study simulated the growth of a self-assembled monolayer (SAM) pattern generated by dip-pen nanolithography (DPN). In this model, the SAM pattern grew mainly via the serial pushing of molecules deposited from the tip. This study examined various SAM patterns, such as lines, crosses and letters, by changing the tip scan speed.

RR Lyrae variables are excellent distance indicators thanks to their visual magnitude-metallicity relation and well-defined Period-Luminosity Relations (PLRs) at infrared wavelengths. These population II variables together with the tip of the red giant branch provide primary calibration for the first-rung of the population II distance ladder. We will present new empirical calibration of RR Lyrae PLRs at near-infrared wavelengths using our data from the ongoing CFHT-WIRCam RR Lyrae program. We will discuss the systematic uncertainties involved in the calibration of these relations based on the latest Gaia EDR3 parallaxes and the implication for the cosmic distance scale.

PURPOSE: To compare postural vertical training with and without visual feedback for improving functional recovery in post-stroke hemiparesis patients with pusher syndrome. METHODS: This study used a single-subject research with alternating design with multiple baselines. Three patients with hemiparetic post-stroke diagnosed with pusher syndrome were selected from the inpatients at the department of physical therapy of a local rehabilitation hospital. For subjective postural vertical (SPV) training with and without visual feedback, an alternating treatment was used. The subjects were randomly selected using the sequence of the two training methods upon starting the intervention, and then the training was alternated. SPV training was performed twice a day, once in the morning and again in the afternoon. Scale for contraversive pushing (SCP), postural assessment scale for stroke, and Barthel index score were used to determine the intervention-related changes. RESULTS: Compared to the average score at baseline, the average SCP score for the SPV training without visual feedback decreased from 5.3 to 2.8, from 4.6 to 3, and from 3.5 to 2.7 for subjects 1, 2, and 3, respectively. However, the average score for the SPV training with visual feedback decreased from 5.3 to 3.1, from 4.6 to 3.5, and from 3.5 to 3.3 for subjects 1, 2, and 3, respectively. CONCLUSION: Postural vertical training without visual feedback may be more beneficial than postural vertical training with visual feedback for improving pushing behavior and functional activity in stroke patients with pusher syndrome.

본 연구에서는 서남극 Canisteo 반도와 그 주변 지역이 촬영된 2쌍의 ERS-1/2 tandem pair에 4-pass DInSAR 기법을 적용하여 표면 변위도를 생성하였고, 빙하와 해빙의 표면 변위를 해석하였다. 표면 변위도에서 빙하는 매우 빠른 움직임을 나타냈으며 인접해 있는 정착빙을 밀어내어 정착빙 표면에서는 빙하와 같은 방향의 변위가 관찰되었다. Cosgrove 빙붕도 큰 변위를 나타냈으며, 인접해 있는 정착빙을 밀어내는 것이 관찰되었다. 일부 해빙은 정착빙과 반대 방향의 움직임을 보였다. 이는 해빙이 해류에 영향을 받는 유빙이기 때문이며, 이로부터 정착빙과 유빙의 경계를 확인할 수 있었다. 빙붕과 빙상의 표면은 SAR영상에서 유사한 밝기를 보이며, 간섭도에서도 비슷한 정도의 간섭띠 변화율을 나타내 두 빙체를 쉽게 구분 할 수 없었다. 그러나 움직임이 큰 빙붕과 변위가 거의 없이 안정적인 빙상의 경계를 절대위상복원 후 생성한 변위도를 통해서 쉽게 확인할 수 있었다.
