Interior design companies in Seoul, Korea, senior level designers-designers shared leadership model has not been implemented by the design management. The whole interior design companies are worked each by a leadership team consisting of senior level designers, contractors and designers, being accountable for company, workers, and budgets. The results for workers' opinion in leadership positions were evaluated. All 154 leading workers of all professional teams were anonymously interviewed with a questionnaire containing 45 items regarding their satisfaction with this new shared leadership model. The response rate was 96.2%. After all, the leading workers were satisfied with the shared leadership model both in their own designing practice and in general. Non-design workers were comprehensively more in favor of quite a few aspects of shared leadership than senior level designers, but even the latter reported to be generally satisfied. However, both professional teams estimated leading positions to be only modestly attractive. The consequences yield some evidence that the transform from traditional leadership models to the senior level designers -designers shared leadership model may have advantages in the management of interior design companies. Furthermore, there is a need for greater clarity about precisely what we mean by shared leadership and also a deeper exploration of potential challenges arising from shared leadership models if we are to try to come to terms with their practice.

Player's actions in a game occur in the process of gameplay experiences in a play space designed by the developer according to preset gameplay beats. Focusing on beats that induce a first-person shooter (FPS) game's main gameplay, this paper analyzes the differences in eye gaze information found in different players during the course of gameplay. For this research goal, the study divides the beat areas in which play actions appear in association with gameplay beats at a typical FPS game level, repeatedly conducts tests in accordance with a player's experience level (novice and expert group), and collects and analyzes eye gaze information data in three types of beat areas. The analysis result suggests concrete guidelines for game level design for different beat areas based on an FPS game player's experience level. This empirical experiment method and result can lessen repetitive modification work for game level design and consequently be utilized for optimizing the game level to the developer's intention.

A small integral reactor SMART (System Integrated Modular Advanced ReacTor), being developed in Korea since late 1990s and targeted to obtaining a standard design approval by the end of 2011, is introduced. The design scope and level for design certification (DC) is well described in the U.S. NRC SECY documents published the early 1990s. However, the documents are valid for a one-step licensing process called a combined operating license (COL) by the U.S. NRC, while Korea still uses a two-step licensing process. Thus, referencing the concept of the SECY documents, we have established the design scope and level for the SMART DC using the contexts of the standard review plan (SRP). Some examples of the results and issues raised during our review are briefly presented in this paper. The same methodology will be applied to other types of reactor under development in Korea, such as future VHTR reactors.

Purpose: The conjoint analyst in marketing are interested in detecting whether there exist synergy or antagonistic effects between two attributes. In the cases where attributes have two or three levels, we research on the design of survey questionnaire to estimate all the main effect and as many two factor interaction effects as possible. Methods: We consider the balanced incomplete block (BIB) mixed level factorial design $2^f{\times}3^g$ or fractional factorial design. To reduce the number of questions in a questionnaire, we propose the balanced incomplete block mixed level design with minimum aberration which is generated by implementing proc factex in SAS. Also, we propose using two or three level BIB factorial design instead of mixed level designs by transforming three level attributes into two attributes of two levels and two level attribute into three level attribute by using dummy level technique. Results: We propose three methods for designing survey questionnaire where the block and design generators are found with practical number of questions in a questionnaire. By analyzing all the respondents survey data generated by the simulation study, we find the proper model and do the concepts optimization. Conclusion: The proposed methods of designing survey questionnaires seem to perform well in the sense that the proper model, and then the optimal concept is found in a case study where all the respondents survey data are generated by the simulation study.

This study was carried out to investigate the effect of design parameters on the volume flow-rate and the noise level and to finally find the optimal design variables. Eighteen cross-flow fans were designed by the method of orthogonal array, and the flow-rate and the noise level were measured. These data were analyzed by the neural network system. The effects of eight design variables(scroll exit angle, scroll arc length et al.) on the fan performance and the noise level were valuated and discussed. This experiment shows that the design solutions suggested by neural network system may increase its volume flow-rate and reduce noise simultaneously.

This study started from the premise that the satisfaction of visitors in large-scaled design-related fair has co-relation with the environmental and contextual factors such as contents, lighting, the number and location of rest area, crowdedness, ventilation and circulation. The research was made in Seoul Living Design Fair 2006. 109 samples from 138 who answered to the questionnaire with likert-scaled and open questions were selected for the data, which were statistically analyzed through SPSS 12.0 program to explore the co-relation between the environmental factors and the satisfaction level of visitors. The findings showed that overall satisfaction level was In the middle of the scale, which means satisfied nor unsatisfied. Even though the visitors had difficulties In circulation and showed various types in circulation. It can be concluded that the main factors should be considered to achieve higher satisfaction level and provide better environment in the large-scaled fair.

The advanced in semiconductor, hardware, and software technologies enables the integration of more com- plex systems and the increasing design complexity. As system design complexity becomes more complicated, System-level design based on the If block and processor model is more needed in most of the RTL level or low level. In this paper, we present a novel approach fur the system-level design, which satisfies the various required constraints and an optimization method of image encoder based on codesign of function, algorithm, and architecture. In addition, we show an MPEG-4 encoder as a design case study. The best tradeoffs between algorithm and architecture are necessary to deliver the design with satisfying performance and area constraints. The evaluations provide the effective optimization of motion estimation, which is in charge of an amount of performance in the MPEG-4 encoder module.

Toguchi method is a systematic technique for designing high quality product at low cost. There are three steps in the Toguchi method, 1)system design, 2)parameter design, and 3)tolerance design. This paper considers the tolerance design for multiple performance characteristics which is practically important. We present two tolerance design procedures : grade selection and tolerance determining procedures. In grade selection procedure a scheme is presented that minimizes the sum of the price of low-level characteristics and the expected loss due to the variations of high-level characteristics. In tolerance determining procedure we determine the tolerances of the low-level characteristics.

The research was made in Seoul Living Design Fair 2005. 102 samples from 132 who answered to the questionnaire with likert-scaled and open questions were selected for the data, which were statistically analyzed through SPSS 12.0 program to explore the co-relation between the environmental factors and the satisfaction level of visitors. The findings showed that overall satisfaction level was in the middle of the scale, which means satisfied nor unsatisfied. The visitors showed relatively high satisfaction in the two factors-the contents of the fair and lighting system compared to the other factors such as the number and location of rest area, sign system, ventilation crowdedness and circulation. Even though the visitors had difficulties in circulation and showed various types in circulation, it did not seem to have a significant influence on the overall satisfaction level because it might be offset by the contents of the fair. Also, the visitors showed similar satisfaction level regardless of the type of circulation. It can be concluded that the main factors mentioned above should be considered to achieve higher satisfaction level and provide better environment in the large-scaled fair.
