The feasibility of a midgap metal gate is investigated for a 32 nm MOSFET for low power applications. The midgap metal gate MOSFET is found to deliver $I_{on}$ as high as a bandedge gate if a proper retrograde channel is used. An adequate design of the retrograde channel is essential to achieve the performance requirement given in the ITRS roadmap. A process simulation is also run to evaluate the feasibility of the necessary retrograde profile in manufacturing environments. Based on the simulated result, it is found that any subsequent thermal process should be tightly controlled to retain transistor performance, which is achieved using the retrograde doping profile. Also, the bandedge gate MOSFET is determined be more vulnerable to the subsequent thermal processes than the midgap gate MOSFET. A guideline for gate workfunction $(\Phi_m)$ is suggested for the 32 nm MOSFET.

Arguably the most important internet technology of today is RIA (rich internet application), whose prime advantage is in improving the user experience on the web. However, the scope and variety of the RIA technology demand an eclectic guideline to build the mathematical services such as mathematical text, graphs, and animations. This paper sorts out and simplifies the complicated roadmap of the RIA technologies by presenting three design patterns for exposing the functionality of the CAS (computer algebra system) with the web browser as the user interface platform.

The feasibility of a midgap metal gate is investigated for 32nm MOSFET low power applications. The midgap metal gate MOSFET is found to deliver a driving current as high as a bandedge gate one for the low power applications if a proper retrograde channel is used. An adequate design of the retrograde channel is essential to achieve the performance requirement given in ITRS roadmap. In addition, a process simulation is run using halo implants and thermal processes to evaluate the feasibility of the necessary retrograde profile in manufacturing environments. From the thermal budget point of view, the bandedge metal gate MOSFET is more vulnerable to the following thermal process than the midgap metal gate MOSFET since it requires a steeper retrograde doping profile. Based on the results, a guideline for the gate workfunction and the channel profile in the 32 nm MOSFET is proposed.

Critical issues in the development targets for the future fast reactor(FR) cycle system, including sodium-cooled FR were to ensure safety assurance, efficient utilization of resources, reduction of environmental burden, assurance of nuclear non-proliferation, and economic competitiveness. A promising design concept of sodium-cooled fast reactor JSFR is proposed aiming at fully satisfaction of the development targets for the next generation nuclear energy system. A roadmap toward JSFR commercialization is described, to be followed up in a new framework of the Fast reactor Cycle Technology development(FaCT) Project launched in 2006.

This paper presents a methodology to nominate and select improvement projects that are perceived as adding value to customers (both internal and external). The structure of the methodology can be explained in three "stages." First, the methodology suggests a new way of categorizing improvement opportunities, i.e. reactive-proactive, to "upgrade" the little Q-big Q categorisation. Then, it develops a roadmap that links performance indicators and improvement projects for both reactive and proactive improvements. Finally, it suggests an algorithm to select the improvement project, where the assessment of to what extent the nominated improvement projects add value to customers relies on the comparison between Overall Perceived Benefits (OPB) and Overall Perceived Efforts (OPE). The improvement project perceived as having the largest impact on adding value to customers receives the highest priority.

This study aims to assess the current status of career education at C University and to gather foundational data for developing a step-by-step career education curriculum and an integrated roadmap for curriculum and extracurricular career education. This research involves a comparative analysis of C University's enrolled students and external university students through a survey using the [University Career Exploration Model]. Data collection took place over one month in October 2023, and statistical analysis was conducted using the SPSS Statistics 25.0 program. The survey results enabled a comparative analysis of the career exploration processes and levels between enrolled students at C University and external university students. The proportion of enrolled students at C University responding positively to the career exploration process and level was high. Through this study, a better understanding of the career exploration processes and levels of university students was achieved. It is deemed necessary to conduct systematic research for continuous, tailored integration of curriculum and extracurricular career education at the university level.

This study discusses the core contents and implications of the design support policy of government in the creation of the designer-makers' business ecosystem through the analysis of 'Young man's Creative Work & Startup Support Project'. This case, which aims to cultivate a design brand based on maker technology and to create jobs for young people, suggests the role of government as a creative culture creator so that designer-makers are able to create creative activities in a more free and creative atmosphere. Furthermore, this study emphasizes the importance of efficient integration and reorganization of similar maker support policies implemented by each government department, the necessity of a roadmap for realizing this, and the support for quality improvement. As a result, the design support policy of government for the designer-makers' business activation should evolve into the qualitative development of intellectual property based on a mature shared culture and the discovery of a new production paradigm model of the manufacturing industry based on the open manufacturers beyond the economic and numerical goals of creating new jobs.

The purpose of this study is to improve the accuracy of service satisfaction by utilizing KSC (Kano, Score Model, Concept Position) analysis methods in order to present various fitness center service models for healthy new silver generation centered on P fitness center which runs six branches in Busan. Double Diamond-based methods led to a case study focused on the P fitness center's Yeon-san branch which well leading in a wide variety of leisure infrastructures for the senior citizens. Throughout this study, based on the insights extracted from the customers were culminating in nine service design models from the perspective of administrators and trainers. The final derived nine models have been evaluated by Kano's satisfaction evaluation, Concept score, and Concept position evaluation. All of the nine models results indicated as valid except for models 3 and 6. Finally, an implementation roadmap was proposed by dividing it into investment cost and effectiveness.

The purpose of the study is to provide design guidelines and space structure of health rooms for elementary and middle schools. In order to do that, with the subject of health teachers from 96 schools in Seoul city, which remodeled the health rooms in 2005 and 2006, the research was carried out. Through the research, we organized the collected opinions and current situation about the procedures of the promotion, size, location and space formation. Based on that, we could acquire a better grasp of a type of space structure for the guidelines. From the research, we realized that in terms of location, size, and internal space structure, it has been improved compared to the past. However, we also saw more rooms for improvements in the coming future. We believe that such result will be utilized as the basic information for the roadmap of new space structure of health rooms at current schools and new schools.
