  • Background in a novel is most important elements with characters and events, and means time, place and situation that characters appeared. Among the background, spatial background can help conveys topic of a novel. So, it may be helpful for choosing a novel that readers want to read. In this paper, we are targeting Korean historical novels. In case of English text, It can be recognize spatial background easily because it use upper and lower case and words used with the spatial information such as Bank, University and City. But, in case Korean text, it is difficult to recognize that spatial background because there is few information about usage of letter. In the previous studies, they use machine learning or dictionaries and rules to recognize about spatial information in text such as news and text messages. In this paper, we build a nation dictionaries that refer to information such as 'Korean history' and 'Google maps.' We Also propose a method for recognizing spatial background based on patterns of postposition in Korean sentences comparing to previous works. We are grasp using of postposition with spatial background because Korean characteristics. And we propose a method based on result of morpheme analyze and frequency in a novel text for raising accuracy about recognizing spatial background. The recognized spatial background can help readers to grasp the atmosphere of a novel and to understand the events and atmosphere through recognition of the spatial background of the scene that characters appeared.

  • Large workspace and strong grasping force are required when a robot manipulates big and/or heavy objects. In that situation, bimanual manipulation is more useful than unimanual manipulation. However, the control of both hands to manipulate an object requires a more complex model compared to unimanual manipulation. Learning by human demonstration is a useful technique for a robot to learn a model. In this paper, we propose an imitation learning method of bimanual object manipulation by human demonstrations. For robust imitation of bimanual object manipulation, movement trajectories of two hands are encoded as a movement trajectory of the object and a force trajectory to grasp the object. The movement trajectory of the object is modeled by using the framework of dynamic movement primitives, which represent demonstrated movements with a set of goal-directed dynamic equations. The force trajectory to grasp an object is also modeled as a dynamic equation with an adjustable force term. These equations have an adjustable force term, where locally weighted regression and multiple linear regression methods are employed, to imitate complex non-linear movements of human demonstrations. In order to show the effectiveness our proposed method, a movement skill of pick-and-place in simulation environment is shown.

  • In this paper, we introduce a flexible gripper that we have engineered to precisely pinch in parallel and compliantly grasp objects. As found in most conventional industrial grippers, the parallel pinching property is essential for precise manipulation. On the other hand, the grippers with a flexible structure are more adept at grasping objects with arbitrary shapes and softness. To achieve these disparate properties, we introduce a flexible gripper mechanism composed of multiple flexible beam structures. Utilizing these beam structures, the proposed gripper is able to grasp arbitrarily shaped objects. Additionally, a unique combination of flexible beams enables the gripper to pinch objects using the parallel fingertips for enhanced precision. A detailed description of the proposed mechanism is provided, and an analysis of the strength and stiffness of the fingertip and finger body is presented. The Results section compares the theoretical and experimental analyses and verifies the properties and performance of the proposed gripper.

  • The purpose of this study was to examine the kinematical characteristics of gymnasts who can perform the KOVACS skill, and to grope for the better KOVACS Piked motion. The subjects were 3 male national gymnasts and were filmed with video cameras. And kinematic data were collected from the event of maximum knee flexion to the re-grasp the bar after airborne motion during KOVACS Piked motion. And the following conclusion were drawn; S1 took the enough time and inadequate height for performing KOVACS Piked motion. S2 showed the inadequate time and height during airborne motion with the large forward-backward and left-right movement. S3 showed the better KOVACS Piked movement among gymnasts, but the weak point of S3 was the large left-right shift. Based on the above conclusions, the gymnasts should be trained the enough time and height for the effective airborne movement and to reduce the left-right movement.

  • Condominium management ask for planning ability and special knowledge in order to solve the troubles of a condominium. But not all HOA have that ability or knowledge, so administration support to condominium management came to be given to HOA. In this study, we divided the administration policies on condominium management as follows;$\circled1$instruction about an advertisement and a contract$\circled2$instruction about management$\circled3$instruction about maintenance $\circled4$ instruction by the local government $\circled5$ legislation about condominium management. The condominium management policy has been almost programmed by the state, such as legal amendments to laws and advises by administrative inspection. But these condominium management policies by the state have limitations to support HOA appropriately, so correspondence of the local government is called for, On the other hand, in the local governments, grasp basic contents for execution to the condominium management policy, an information of offering and consultation has been started. And system that suits the situation and the characteristic of each district was provided. However it could not say that we grasp the tendency of the condominium management policies wholly of the local governments, so it remains as a subject because it is not long since condominium management policies of the local government started, and we picked up only metropolis in this study. In the future, it is necessary to search on the consciousness of a resident and the HOA about the condominium management policy, and make out the data which can be reflected in policy deployment in the local governments from now on. * HOA ‥‥ Home Owners Association

  • Government itself produces a vast amount of highly valuable information, and the internet increases its potential social and economic value. So far, government provide web services that is web 1.0 style. To meet the user's needs, that is online collaboration and sharing, government web services also change to web 2.0. This paper argues that government could now grasp the opportunities that are emerging in terms of web 2.0. Current policy and action is not yet adequate to grasp these opportunities. So, this study focused on the strategic development of electronic government services based on web 2.0. For the purpose, we reviewed the web 2.0 cases and former electronic government services. And then, we defined government 2.0 that is electronic government services based on web 2.0, and provided reference model of government 2.0. Government 2.0 reference model will help the administrators to find better ways to use the technological infrastructure and save efforts for trial and errors from the lack of systematic approach.
