Most concrete is recently made of an aggregate which is properly absorbed, and carried in it in order to do capability at every fields. We have been close to demand new capability of high flowing and enduring for specific concretes. That is difficult to cope with claiming the efficiency on deterioration from lack of a high quality aggregate. Therefore, For solving the problems we apply to a packing method for using dried materials. That is to say it is a kind of making into an instant. In this study, There is a purpose to present fundamental data, comparing and analyzing a phenomenon about aggregate's absorption following the rate of adding water, for using existing materials.

In designing and evaluating manipulators, itis important to understand the capability of kinematic and static performances. Both workspace and manipulability can be considered as such performance measures. In general, the measure of manipulability is related to the kinematics for serial type manipulators. However.in case of parallel manipulators such as Stewart Platform, the manipulability can be interpreted as the static capability of transforming the input forces of actuators to the wrench of the end-effector. In this paper, the mathematical and physical meanings of manipulability suggested in some research works have been examined, and more meaningful measure of manipulability using the absolute minimum eigenvalues of J $^{T}$ .del. J has been suggested, which has been applied to a Stewart Platform in order to investigate the manipulability of this mechanism..

We describe a 32" liquid-crystal display (LCD) with multi-touch sensing capability by integrating IR detector arrays onto the LED backlight plate. A transparent light guide is placed in front of the display screen, with IR LEDs disposed at its edges and emitting IR light into the light guide, the light is trapped by total internal reflection within the light guide to be as touch-sensing light. A physical contact with the acrylic plate surface will stimulate some trapped light to be escaped from the light guide and pass through LCD panel to be detected by the IR detectors. The touch-sensing LCD with this configuration can locate simultaneous multiple touche points on the touchable surface.

As a definition of NERC, Available Transfer Capability(ATC) is a measure of the transfer capability remaining in the physical transmission network for the future commercial activity. To calculate ATC, accurate and defensible TTC, CBM and TRM should be calculated in advance. In this paper, we propose a method to quantify TRM using probabilistic load flow based on the method of moment. Generation output, bus voltages, loads, and line outages are considered as complex random variables (CRV) to take into account for uncertainties related to the transmission network conditions. Probability Density Function (PDF) of line flow at the most limiting line is used to quantify TRM with the desired probabilistic margin. Suggested method is compared with the results from conventional CPF method and verified using 24 bus MRTS, and the suggested method based on PLF shows efficiency and flexibility for the quantification of TRM compared with the conventional method.

In Experimental Advanced Superconducting Tokamak (EAST) experiments, to achieve long pulse and high-power ICRH system operation, a new kind of ICRH antenna has been designed. One of the most critical factors in limiting the operation of long pulse and high power is the intense heat load in the front face of the ICRH antenna, especially the Faraday Screen (FS). Therefore, the cooling channels of FS need to be designed. According to thermal-hydraulic analysis, the FS tubes are divided into several groups to achieve more excellent water cooling capability. The number of series and parallel tubes in one group is chosen as six. This antenna went into service in the spring of 2021, and it is delightful that the temperature distribution of the FS tube is below 400 ℃ in 14.5 s and 1.8 MW ICRH system operation. However, the active water-cooling design was not carried out on the upper and lower plates of FS, which led to severe ablations on that region under long pulse and high power operation, and the temperature is up to 800. Therefore, the upper and lower side plates of the FS were designed with water cooling based on thermal-hydraulic analysis. During the 2022 winter experiments, the temperature of ICRH antenna FS was lower than 400 in the pulse of 200s and the power of 1 MW operation.

The purpose of this study suggest that Park Golf for rehabilitation training of the patients with hemiplegia. The increase of the aged caused various problems. Among the problems, chronic illnesses the old people suffer from charge their family with mental, physical, social and economic burden as well as the person. Especially, the more old people are the more risks and attacks of cerebral vascular accident(CVA) exist. Therefore, the increase of the aged means the increase of cerebral vascular accident(CVA) patients. The cerebral vascular accident(CVA) patient get into difficulties to secure their livelihood due to troubles and disoders, so medical care facilities and rehabilitation training are really necessary to help them return to their normal life with mental, physical and social capability. The rehabilitation of patient with hemiplegia is ongoing process. It may possibly accomplish throughout the whole life because it takes a lot of time and effort. In addition, an ultimate aim of the rehabilitation is returning and adaptation to society. In this way, it is hardly to expect a satisfied results of the rehabilitation without motive. Therefore, patient with hemiplegia rehabilitation motive will is the most important. If interesting of park golf the patient with hemiplegia can be absorbed in easily are applied to the rehabilitation training, the patient are will to participate in the training without troubling.

This paper presents $H{\alpha}$ emission line detections for four galaxies at z > 3.5 made with AKARI as part of the FUHYU mission program. These are the highest-redshift $H{\alpha}$ detections to date in star-forming galaxies. AKARI's unique near-infrared spectroscopic capability has made these detections possible. For two of these galaxies, this represents the first evidence of their redshifts and confirms their physical association with a companion radio galaxy. The star formation rates (SFRs) estimated from the $H{\alpha}$ lines under-predict the SFRs estimated from their far-infrared luminosities by a factor of ~ 2 - 3. We have also detected broad $H{\alpha}$ components in the two radio galaxies which indicate the presence of quasars.

이 연구는 무용심상 훈련프로그램을 통해 무용수들이 인식하고 있는 신체지각과 창의적사고의 관계성을 밝히고자 시도하였다. 무용수의 내적심상과 외적표현은 자기감응의 확산적 표현과정이며, 신체지각과 창의적 사고의 관계성을 입증하였다. 그 핵심은 상상력을 통한 문제인식과 해결의 적극적인 사고과정이며, 새로운 지각과 그 소통능력을 의미한다. 그러므로 무용심상은 신체와 정신의 통합원리에 근거한 지각훈련이고, 폭넓은 내적상상의 다양성과 외적표현의 적극적인 사고를 통해 새로운 소통을 창조해야 한다.
