The Purpose of this study were to identify school uniform satiafaction factors and to compare Parents. teachers. and students' middle and high school uniform satisfaction. Respondents were middle and high school parents. teachers. and students in Chonbuk province and data was collected during March, 2002. Frequencies. percentages. and mean were calculated. ANOVA. Chi-square test. reliability test were done. The results were as follows : 1. The school uniform satisfaction was composed of 5 factors of symbolism. design. management and comfort. durability and economy. and fitness. The satisfaction level of symbolism was the highest. and the management and comfort was the lowest. 2. The school uniform satisfaction level was relatively low. Teacher's school uniform satisfaction level was the highest. and students' satisfaction level was the lowest. The parents' satisfaction level of management and comfort. durability and economy. and fitness were the highest. and the teachers' satisfaction level of symbolism and design were the highest. 3. The parents and teachers' satisfaction level of symbolism and students' satisfaction level of school uniform design were higher under the strict school regulation on school uniform. Parents. teachers and students who agreed to the school uniform Policy showed higher school uniform satisfaction.

This study was intended to investigate the designs that are displayed on fashion windows, specifically the originality of its designs, from here on noted as "design originality", and the effects it has on the attitudes of consumers toward fashion brands and their purchasing intentions depending on their level of clothing involvement. For the purpose of this study, 10 pictures of creative fashion window display designs from Fifth Avenue in New York were selected and they were shown to 200 college students in Busan in order to collect data for the analysis. The results are as follows: 1) Factor analysis identified four factors that impacted how consumers judged design originality, uniqueness, humor, favorable impression and advanced design. 2) The four factors of design originality in fashion window display significantly affected consumer's evaluation on usefulness of information provided by the window display, attitudes toward fashion brands and purchase intention. 3) The respondents were separated into two groups depending on their level of clothing involvement. Consumers with high level of clothing involvement showed that they were influenced more by the design originality when making purchase decisions. Especially, the uniqueness factor and advanced design factor had more effect on brand attitudes and purchase intention in high level of clothing involvement group. The results revealed that creative fashion window display design are important marketing strategic tools that affect attitudes of consumers toward brands and their purchasing intentions.

Purpose: In this study, an optimal design level of influencing factors on semiconductor polishing process was determined to minimize flexion of both sides on wafers. Methods: First, significant interactions are determined by the stepwise regression method. ANOVA analysis on SN ratio and mean of dependent variable are performed to draw mean adjustment factors. In addition, the optimal levels of mean adjustment factors are decided by comparing means of each level of mean adjustment factors. Results: As a result of ANOVA, a mean adjustment factor was determined as a width of formed flexion on the plate. The mean of the difference has the nearest to 0 in the case when the width of formed flexion has level 2 (4mm). Conclusion: Optimal design levels of semiconductor polishing process are determined as follows; (i) load applied to the wafer carrier has a level 1 (3psi), (ii) load applied to the wafer has a level 1(3psi), (iii) the amount of slurry supplied during polishing has a level 3 (300 co/min), (iv) the width of formed flexion on the plate has level 2 (4mm).

One of important design challenges in Chongqing Raffles City Plaza project is Sky Bridge structural design and its connection scheme in high level. This article systematically describes the structural system and its design and analysis methodology, with discussing the impacts on structural performance due to different connection approaches. The seismic isolation scheme in high level is innovatively adopted to the final design. Under the conditions of various load cases, the different models and assumptions are implemented. A full assessment on Sky Bridge's structural performance, seismic isolation, and its connection is conducted in terms of seismic performance based design. By co-operating with architecture, MEP and other disciplines, the structural economy index is fulfilled.

After the change of curriculum in the Year 2000, Partial extensions and renovations were carried out for functional correspondence. Despite of the importance of contextual consideration for facade, Leaning to curriculum and function leads to visual problems between old existing and new building in many case of educational facilities. therefore Design Guidelines for the Facade of extension and renovation are needed. In this study, First, made a survey of the level of satisfaction and harmony of facade of extensions and renovations on elementary schools which have extended and renovated since the Year 2000. secondary, analyzed the interrelationship between the level of satisfaction and harmony and design elements of facade of extension and renovation and lastly, derived design guidelines from them. Results of this study are as follows; 1) The more latest building, the more high in the level of satisfaction and harmony 2) The sequences of the level of satisfaction in finishing materials are as follows : stone>brick>paint 3) When the proportion of existing to new building over a half, higher level of satisfaction appears on the whole. 4) How overcomes the gap of time is the matter in the facade design of extension and renovation.

The 2-way balanced one-level rotation design has been discussed (Park et al., 2001), where the 2-way balancing is done on interview time in monthly sample and rotation group. We extend it to 3-way balanced multi-level design to obtain more information of the same sample unit for one or more previous months. The 3-way balancing is accomplished not only on interview time in monthly sample and rotation group but also on recall time as well. The 3-way balancing eliminates or reduces any bias arising from unbalanced interview time, rotation group and recall time, and all rotation groups are equally represented in the monthly sample. We present the rule and rotation algorithm which guarantee the 3-way balancing. In particular, we specify the necessary and sufficient condition for the 3-way balanced multi-level rotation design.

This paper proposes and describes the design and operational principles of a three-phase three-level nine switch voltage source inverter. The proposed topology consists of three bi-directional switches inserted between the source and the full-bridge power switches of the classical three-phase inverter. As a result, a three-level output voltage waveform and a significant suppression of load harmonics contents are obtained at the inverter output. The harmonics content of the proposed multilevel inverter can be reduced by half compared with two-level inverters. A Fourier analysis of the output waveform is performed and the design is optimized to obtain the minimum total harmonic distortion. The full-bridge power switches of the classical three-phase inverter operate at the line frequency of 50Hz, while the auxiliary circuit switches operate at twice the line frequency. To validate the proposed topology, both simulation and analysis have been performed. In addition, a prototype has been designed, implemented and tested. Selected simulation and experimental results have been provided.

In computer games, the level design and balance of characters are the key features for developing interesting games. Level designers make decision to change the parameters and opponent behaviors in order to avoid the player getting extremely frustrated with the improper level. Generally, opponent behavior is defined by static script, this causes the games to have static difficulty level and static environment. Therefore, it is difficult to keep track of the user playing interest, because a player can easily adapt to changeless repetition. In this paper, we propose a dynamic scripting method that able to maintain the level designers' intention where user enjoys the game by adjusting the opponent behavior while playing the game. The player's countermeasure pattern for dynamic level design is modeled using a Gaussian Mixture Model (GMM). The proposed method is applied to a shooting game, and the experimental results maintain the degree of interest intended by the level designer.
