  • MMORPG is being progressed through Quest and the level and the balance are realized. Also, Quest plays a strong role of motivation through compensation related with Avatar such as items and experience points rather than a role of story transfer. This situation finally made MMORPG become a difficult game that players should study the compensation of Quest for growth of a character, so it causes fixation of the user class. As a solving method of the fixation of the users, the possibility of Quest capable of strengthening play motive of various users through clarification of motivation structure of the Quest play and pluralistic understanding about players was investigated. The pluralistic understanding method of players will have values as a tool that can design and evaluate Quest satisfying preference of the various user class.

  • In this paper, we propose a training method to efficiently create prototypes using 'core mechanical diagram' to make game design easier and 'BluePrint', a visual scripting tool of Unreal that enables relatively easy functionality without programming knowledge. With the development of game engines, game development is becoming faster and easier, and using this, non-programmers without knowledge of game development are clearly showing a tendency to participate in game development. However, existing game development methodologies and game implementation methods require complex design processes and specialized knowledge. In order to make it easier for non-programming experts to develop games, they will simplify the complexity of existing game development methodologies, and propose educational methods that can focus on and implement the essence of game design based on cases where non-programmers have implemented prototypes themselves.

  • In this paper, we investigated abnormal ESD failure on guard-rings in the smart power IC fabricated with $0.35{\mu}m$ Bipolar-CMOS-DMOS (BCD) technology. Initially, ESD failure occurred below 200 V in the Machine Model (MM) test due to current crowding in the parasitic diode associated with the guard-rings which are generally adopted to prevent latch-up in high voltage devices. Optical Beam Induced Resistance Charge (OBIRCH) and Scanning Electronic Microscope (SEM) were used to find the failure spot and 3-D TCAD was used to verify cause of failure. According to the simulation results, excessive current flows at the comer of the guard-ring isolated by Local Oxidation of Silicon (LOCOS) in the ESD event. Eventually, the ESD failure occurs at that comer of the guard-ring. The modified comer design of the guard-ring is proposed to resolve such ESD failure. The test chips designed by the proposed modification passed MM test over 200 V. Analyzing the test chips statistically, ESD immunity was increased over 20 % in MM mode test. In order to avoid such ESD failure, the automatic method to check the weak point in the guard-ring is also proposed by modifying the Design Rule Check (DRC) used in BCD technology. This DRC was used to check other similar products and 24 errors were found. After correcting the errors, the measured ESD level fulfilled the general industry specification such as HBM 2000 V and MM 200V.

  • The aim of this study is to suggest a new website measurement scale revised in accordance with the present tendency, and to test the practical use of it. The empirically current studies suggest the information, connectivity, practical function, lay - out, design, interlace, system, service as a website measurement scale. However. this study suggest a new website measurement scale including communication between internet users, platform for editing information. The test of a practical use about measurement scale progressed by a survey on computer access. A sample of 300 internet users answered the question based on a new website measurement scale. The result of this study shows that primary factors of the website measurement scale are information, user interface, website service, and communication. The influence of these factors on user's website preference changed as compared with the past. The result also shows that there is close correlation between information factor and communication factor. And the communication factor suggested on this study has effected in user's website satisfaction. Results imply that the idea of web2.0 is practically an important strategy for improving website satisfaction. And, because influence of primary factors on the website satisfaction has changed continually, strategic planning will have to be kept up.

  • Terahertz (THz) time-domain spectroscopy(TDS), imaging techniques, and related systems have become mature technologies, widely used in many universities and research laboratories. However, the development of creative technologies still requires improved THz application systems. A few key points are discussed, including the innovative advances of mode-locking energy-emitting semiconductor lasers and better photoconductive semiconductor quantum structures. To realize a compact, low cost, and high performance THz system, it is essential that THz spectroscopy and imaging technologies are better characterized by semiconductor and nano-devices, both static and time-resolved. We introduce the THz spectroscopy and imaging systems, the OSCAT(Optical Sampling by laser CAvity Tuning) system and the ASOPS(ASynchronous Optical Sampling) system, are constructed by our research team. We report on the THz images obtained from their use.

  • As recent multilateral collaboration design system has been advanced, BIM based data exchange is a key factor for successful next generation building project. Even though many studies have been trying to set up a data compatibility system for collaboration, There are still a lot of problem in data exchange between design and engineering phase. Therefore, In this study, we analysis causes of problem for information exchange and suggest a IFC based Information exchange framework for improving BIM based design collaboration environment. In order to find out problems that hinder establishment of advanced open BIM information exchange, proper analysis about transition of process from current and to-be BIM based design collaboration process is important, at first. From analysis of main obstacles to information exchange, this research suggests solution plan using open API and IFC based BIM collaboration supporting system. The suggested open API solution named Integrity feedback system perform a role making up for weak point derived from IFC based data exchange. And main system suggestion about framework for IFC based information exchange reflect technological system support, requirement of function for collaboration including API/BCF plug-in.
