The post-war period has witnessed the emergence of new towns in a number of countries in Southeast Asia. New town development started in Malaysia with Petaling Jaya as a satellite town in 1953 to accommodate the rapid growing population of Kuala Lumpur. New towns have been designed in accordance with the British town planning principles, based on the modern ideal city. Nonetheless, they have constituted a regional character as they have incorporated local factors such as local technologies as well as site and climatic conditions. In the shaping of the new towns in modern cities, regulatory aspects have played important roles. The regulations decide the basic framework for planning of new town, block plan and unit plan. The ultimate goal of this study is to understand the identity of the new town planning of Malaysia. As a first step, we reviewed the local regulations, standards, and design guidelines which are applicable to the new town planning from the national land use to local plans. As a result, we categorized the guidelines into four areas: urban space, site plan, street system, block plan and unit plan. We expect this study to provide the framework of the Malaysia's new town planning from the perspective of the local regulations.

A universal design means a progressive and challenging design in the 21st century which can satisfy the demands from not only aged people and disabled people but also numerous members of our society. This research aims to apply a universal design commonly used in architecture (environment) and products to costumes, so as to convert the design into a universal fashion which can meet the aesthetic values, desires, and functionality of aged people and disabled women. After applying the said five universal fashion principles and design factors, a total of 20 pieces of universal fashion prototype products are produced through functional designs and designs utilizing knit materials and health & functionality materials. In addition, a direction to develop universal fashion products is suggested for costume manufacturers, for the purpose of facilitating the practical use of a universal fashion. The present author expects that human-centered universal fashion costumes shall propose the orientation of the interest in future new designs, beyond the scope of a jump in the quality of simple functional costumes.

In creative society, fluency in technology means the ability to reformulate knowledge, to express oneself creatively and appropriately, to produce and generate information in computer environment. Fluency in technology is essential for mathematics education with a point of constructivist view. In this paper, we study the meaning of fluency in technology, related to mathematics education. For this purpose, we suggest Papert's constructionism as a theoretical background and consider the principle of 'Learning through design' for fluency in technology. And we consider some principles for designing a mathematical microworld and implement a mathematical microworld for fluency in technology. With this microworld, we consider the after-school-program where students have participated a design activity.

Since the first success of simple mastoidectomy, about 100 years ago by Schwartze (1873). Zollner (1951) and Wullstein (1952) had formulated systemically the basic principles of restorative surgery of chronic ear diseases. Although the last century has shown a remarkable advances in surgical technique, there are still lots of debatable problems yet. The authors experienced 970 cases of middle ear surgery during last four years and clinical and statistical analysis were done as a preliminary report.

Today the realization of a welfare society is urgently needed as growing of economy. To promptly meet the needs of the times, the ratio of a matriculation of the physically disabled is getting higher, stretching opportunities of a higher education. But, the walk environment in university educational facilities is still insufficient because of the indifference to the education of the physically disabled. The purpose of this research is to suggest the direction to improve the walk environment for all users through evaluation of the accessibility of the walk environment in university educational facilities, and the scope of the research is the internal and external walk environment of university educational facilities. The first step of the research is preparatory study review to extract the elements of the accessibility of the Universal Design Principles. And then, we evaluate the accessibility of university educational facilities through the site visits. The results of this research are as following: 1) The internal and external walk environment of university educational facilities needs more physical improvement for keeping accessibility. 2) We need to provide consistent guidances from the external sidewalks to main entrances, slopes, staircases, elevators, and corridors. 3) The walk environment of university educational facilities needs to maintain continuously.

Demand of Auto Focus for Camera module is increased very fast in these days and will be adapted to most of mobile phones in next few years instead of traditional method, fixed focus. To make auto focus function, 2 kinds of solutions, VCM(Voice Coil Motor) and Piezo linear motor are normally used. In this paper, VCM which commercially strong candidate for Auto focus mechanism was investigated to verify principles are match up to the actual operation. Auto focus algorithm is different between 1 chip and 2 chip solution. Normally 2 chip is more complicate than the other. To have best performance on this function, hysteresis and depth of field(DOF) table should be optimized.

We have designed a 32-bit microprocessor with fixed point digital signal processing functionality. This processor, combines both general-purpose microprocessor and digital signal processor functionality using the reduced instruction set computer design principles. It has functional units for arithmetic operation, digital signal processing and memory access. They operate in parallel in order to remove stall cycles after DSP or load/store instructions, which usually need one or more issue latency cycles in addition to the first issue cycle. High performance was achieved with these parallel functional units while adopting a sophisticated five-stage pipeline stucture.

This paper presents a useful multilevel PWM inverter scheme based on a (3$^{n-1}$+2) level generation technique. It consists of a PWM inverter, an assembly of LEVEL inverters, and cascaded transformers. To produce high quality output voltage waves, it synthesizes a large number of output voltage levels using cascaded transformers, which have a series-connected secondary. By a suitable selection of secondary turn-ration of the transformer, the amplitude of an output voltage is appeared at the rate of an integer to an input dc source. Operational principles and analysis are illustrated in depth. The validity of the proposed system is verified through computer-aided simulations and experimental results using prototypes generation output voltages of an 11-level and a 29-level, respectively. And their results are compared with conventional counterparts.

In this paper, we provide efficient spectrum sensing technology for smooth use of frequency and energy charge of multi-copter. The proposed structures focus on improving performance of spectrum sensing that is based on Ad-hoc network. First, we explain basic principles and disadvantages of cooperative spectrum sensing and ad-hoc based spectrum sensing. To solve these problems, in this paper, we employ the beamforming technology that guarantees higher transmit primary users' signal power to secondary users in ad-hoc network. The performance of proposed algorithm is analyzed in terms of detection probabilities, and the results of this paper can be applied to the various ad-hoc based Cognitive Radio system.

The purpose of this study is to find out the characteristics of the office space as designed by Gwathemy Siegel and thereby to understand the current trend of interior design of working space in the United States. Unlike most architects, Gwathmey Siegel have extended themselves into interior designing of over twenty offices including law firms, financial institutions and design firms and have successfully won reputation as interior designers. They have distinguished themselves by their ability to turn up and take advantage of the possbility of shaping in a given structure. Their liberal use of fixed furniture and architectural lighting , in addition to ceilings and walls , set them apart from others in the field . The major design elements and principles of Gwathmey Siegel include, among others : 1) Curved and slanted walls on the floor plans endow the office space with forms. Fixed furniture and architectural lighting frequently serve as from -creating elements. 2) The openness of the reception and waiting areas and the irregularity of the corridor walls add a sense of variety in the office. 3) In terms of color and materials, subtle changes of texture and value and the various patterns of joint lines further enrich the space. 4) The principle of symmetry , rough or partial , as applied in the layout of rooms and furniture creates a sense of balance in the space.
