  • The realization of the photoresist(PR) removal method with vaporized water and ozone gas mixture has been studied for the LCD TFT array manufacturing. The developed PR stripper uses the water boundary layer control method based on the high concentration ozone production technology. We develop the prototype of PR stripper and experiment to find the optimal process parameter condition like as the ozone gas flow/concentration, process reaction time and thin boundary layer formation. As a results, we realize the LCD PR strip rate over the 0.4 ${\mu}m/min$ and this PR removal rate is more than 5 times higher than the conventional immersion type ozonized water process.

  • This study tests e-business performance difference of the inter group by strategy type through the cluster analysis, after confirming the linear relationship between the e-business strategy type and its performance. According to the result of the study the effect on the e-business performance reveals to differ by the e-business strategy type. That is to say, while the firm's information system performance, e-business realization and the inter group competition dominance are affected positively by the e-process strategy, web application strategy and customer attracting strategy. This confirms that the information system performance, the realization performance and the competition dominance are affected by e - business strategy type. The key factor leading to the success of e-business is the commitment of e-process strategy and web application strategy. For the case of the customer attracting strategy the result shows the importance of the strategy. In the cluster group analysis, the additional analysis, the effect is seen to be more powerful in the firm's information system performance, e - business realization and securing the competition advantage for the case of the multiple strategy than that of single one. Accordingly, the firm needs to adopt the multiple strategy suited for the characteristic of the firm rather than the single strategy.

  • This paper discusses a distributed implementation of the Biba security policy model. Implementation of an service in the OSI-RM is not sufficient for enforcing the Biba model. Also confidentiality services are necessary. Public Key Systems(PKSs) are considered for the realization of these security services. In this paper symmetric & asymmetric cryptographic systems are considered for the realization of these security service. It is investigated how key-distributions can be found resulting in a minimum number of key.

  • We propose a three-electrode type electronic paper display and its fabrication process to realize single color at the same display panel. We establish a fabrication process with the mixing of electronic ink, loading of this ink, electronic ink assembly, packaging and driving. Also, we discuss an operating principle of this panel and the induced image reversal phenomenon by electric field area of the lower electrodes. This phenomenon is not occurred for the panel having $10{\mu}m$ electrode space. By this pixelation structure like this three-electronic paper display, a single color realization without color filter is possible and various kind of color is defined by a dye selection for charged particles and electrically neutral fluid.

  • In this work, optimization analysis has been accomplished to find important process factors for realization of vertical wall around holes punched by the punchless piercing process. Taguchi method was used for optimization analysis. Lemaitre damage theory, one of the ductile fracture models, was also adopted to simulate numerically formation of vertical wall. From the results of analysis the most influencing factor that affects the vertical wall has been revealed to be 'Corner Radius of Die'.

  • There have been many research papers and practical implementations on the various EC(Electronic Commerce) aspects such as merchant system, security, payment gateway, legal and policy issues. However, it is very hard to find the systematic approaches and business process models from the viewpoint of the company willing to start B2C(Business-To-Customer) EC. Therefore, we develop business process models for the planning, systems analysis and design, implementation, and operation of internet shopping mall to suggest a guideline and reference model for the realization of successful B2C EC.

  • Information Technology represents substantial financial investment for government organization. However, it seems that the real goal of IT investment, which is to make government more efficient, effective, and responsible through IT systems, has not been seriously aware of in the government organizations. As a result, despite of large investment in IT over many years, substantial benefits accrued to the work, such as process innovation and work efficiency, have not actually occurred. In this paper, it is argued that, since IT benefits will not be realized without any effective benefits realization efforts, it is needed in IT evaluation to put more emphasis on the efforts. Therefore, it is suggested that appropriate IT evaluation can possibly work as a guideline for deriving the desired benefits through the IT investment. In this study, some of the well known approaches were reviewed about what IT evaluation and IT benefits realization efforts should be. Current evaluation method was analyzed from the perspective of benefits realization. On the basis of the analysis, this study leads to suggestions that improve the current ways of evaluating IT performance, helping government focus on realizing practical IT benefits at work.

  • As the title signifies, the current study aims at the realization of u-City, which is short for the Ubiquitous City. For this purpose, firstly, the meaning of u-City realization is sought in the study based on future urban changes. Along with this, current issues in the course of u-City realization are gathered based on in-depth interviews with relevant experts. Thirdly, necessary for the comprehensive planning and management of u-City, several strategies are presented by classifying it into u-Infra and u-Service, and considering relevant laws and regulations. And the study divided the execution process into project, development and management levels, and then suggests some realization strategies that are level-dependent.

  • This paper presents a power-efficient hardware realization for a motion estimation technique that is based on the full-search block matching algorithm (FSBMA). The considered input is the quarter common intermediate format of digital video. The mean of absolute difference (MAD) is the distortion criteria employed for the block matching process. The conventional architecture considered for the hardware realization of FSBMA is that of the shift register-based 2-D systolic array. For this architecture, a conservative approximation technique is adapted to eliminate unnecessary MAD computations involved in the block matching process. Upon introducing the technique to the conventional architecture, the power and complexity of its implantation is reduced, while the accuracy of the motion vector extracted from the block matching process is preserved. The proposed architecture is verified for its functional specifications. A performance evaluation of the proposed architecture is carried out using parameters such as power, area, operating frequency, and efficiency.
