In this paper, each step of microprogramming was discussed using a microprogrammable machine that would grasp the characteristics of the microprogram in close relation to the hardwares and microinstruction definable language which make an effective microcode. This was proposed for an environment which minimizes costs.

An optimal graspiftg algorithms for a multifingered robotic hand is proposed, where a new quality measure is developed to evaluate task-oriented as well as stability by modelling the tasks as ellipsoids. To show the validities of the proposed algorithm, several numerical examples are presented by employing a 3-fingered robotic hand.

This study dealed with problem to estimate the uniformity of dust clouds, as a fundamental study to estimate the ignition hazardous evaluation of hybrid mixtures. The developed method was proposed to grasp space distribution of dusts, and also, an experimental apparatus considering with dispersion and reproduction of dusts were uniquely devised and studied.

In this study, we have analyzed the running performance of Mugungwha coach in curves to grasp the problems relating to this coach's curving performance and present improvement plans. Simulations and tests to analyze curving performances are carried out, and through this Process we could prepare a plan to improve the running performance in operation.

The Goth style arouses Medieval syndrome, nostalgia and decadence, considering that Goth style shown in the contemporary fashion rend, tradition and fantasy that appeared in transition of the 21st century. This study is based on documents related to real Goth festivals and events to grasp various characteristics of Goth street style. The Goth style shown in high fashion classified the style on the basis of characteristics of camp culture from the viewpoint of bottom up from non-mainstream to mainstream with catwalk as the central figure. Considering appearance of Goth, property of subculture after the 1980s as alternative subculture as well phenomenon of latter subculture. Also it was possible to grasp attribute of lifestyle shown in music and fashion code from the viewpoint that alternative subculture was in pursuit of individual personality and autonomy. As an alternative subculture, Goth that appeared in UK from the late 1970s to the early 80s is considered new lifestyle, which means the scene of modern underground.

The focus of this paper is the designing a flexible three fingered hand system with 16 D.O.F for dynamic manipulation with an intelligent controller, and to build a useful database for dynamic manipulation based on the experimental results. The weight of the hand module is only 0.7 kg, but flexible motion and powerful grasping are possible. To achieve such a dynamic motion in a robotic hand, we have developed a flexible fingered hand with a control system incorporating image recognition system in which we deal with the problems of not only accuracy and range of motion but also the flexibility of hand. The fingers are arranged so as to grasp both circular and prismatic objects. In order to achieve the light mechanism, we reduced the number of joints and fingers as much as possible. We used three fingers, which is the minimum number to achieve a stable grasp.

In previous studies, memory storage was localized to engram cells distributed across the brain. While these studies have provided an individual cellular profile of engram cells, their synaptic connectivity, or whether they follow Hebbian mechanisms, remains uncertain. Therefore, our recent study investigated whether synapses between engram cells exhibit selectively enhanced structural and functional properties following memory formation. This was accomplished using a newly developed technique called "dual-eGRASP". We found that the number and size of spines on CA1 engram cells that receive inputs from CA3 engram cells were larger than at other synapses. We further observed that this enhanced connectivity correlated with induced memory strength. CA3 engram synapses exhibited increased release probability, while CA1 engram synapses produced enhanced postsynaptic responses. CA3 engram to CA1 engram projections showed strong occlusion of long-term potentiation. We demonstrated that the synaptic connectivity of CA3 to CA1 engram cells was strengthened following memory formation. Our results suggest that Hebbian plasticity occurs during memory formation among engram cells at the synapse level.

In case of the working machine that using in the loud-noisy workplace, as it generates the loud-noise, it is influencing a physical, mental bad effect to those workers. Accordingly, though the noise countermeasure for the loud-noisy workplace is acutely requiring, until now, those methods that wearing the soundproof-protection tool, or restriction the working hours, and minimize the noise exposure volume, were mainly used. However, such noise countermeasures occur many problem points. On such point of view, using the acoustic simulation technique, let the workers to choose the workplace where suffering many damages due to the noise of working machine, and after grasp the physical property of working machine and indoor acoustic characteristic, this Study has attempted to grasp the reduction degree of noise level at before-improvement?after-improvement, through the sound-absorption measure. Passing through such preceding step, using auralizational technique based on the noise of working machine of before-improvement after-improvement, and by conduct psycho-acoustics evaluation, this study intended to investigate the change degree of subject reaction. As the result of evaluation, it is considering that the noise-reduction countermeasure method for the loud-noisy workplace could be much effective, through the sound-absorption measure.

Our government has used the result of National Assessment of Educational Achievement(NAEA) with one of data to check and improve the existing curricula and educational policies. The reason to devote these efforts is for the purpose of boosting the students' academic ability. Here, one of works based on the growth of the students' academic ability is to grasp what contents they are vulnerable to. Next work is to improve the methods to teach the appropriate content. So, in this paper I grasped the tendencies of the whole students and male/female students in middle school to appear in the results of 2010, 2011 NAEA. On the basis of those I grasp what contents the whole students and male/female students are vulnerable and I suggest the implications of teaching and learning for those contents.
