This paper presents 3D graphics lighting processor based on vector processing using pipeline chaining. The lighting process of 3D graphics rendering contains many arithmetic operations and its complexity is very high. For high throughput, proposed processor uses pipelined functional units. To implement fully pipelined architecture, we have to use many functional units. Hence, the number of functional units is restricted. However, with the restricted number of pipelined functional units, the utilization of the units is reduced and a resource reservation problem is caused. To resolve these problems, the proposed architecture uses vector processing using pipeline chaining. Due to its pipeline chaining based architecture, it can perform 4.09M vertices per 1 second with 100MHz frequency. The proposed 3D graphics lighting processor is compatible with OpenGL ES API and the design is implemented and verified on FPGA.

Presented in this study is a top-down functional requirement analysis procedure and the desired functionalities for PDM system development, and the benefits of top-down approach over a conventional bottom-up approach is also shown. For the purpose of top-down requirement analysis for PDM system, this study proposes 4P modeling view. 4P modeling view is defined as a modeling perspective for classifying functional requirements and integrating product-related information objects that must be man-aged within PDM systems. Based on 4P modeling templates, benchmarking analysis of commercially major PDM products is conducted and as a result of this analysis, this study suggests desired functionalities for PDM system.

Clothing for hospitalized patients is very important because they wear it while they suffer from various kinds of pain and treatments. Therefore, the clothing for patients has to be comfortable and functional as well as well designed. Also correct sizes, suitable materials and convenient fastening devices are features to be considered for proper patient's clothing. However the currently used patient's clothing is provided without sufficient considerations for patient's needs, and is more concerned with price competitiveness. The purpose of this survey was to find out which design and functional features of patient's clothing are favored by patients, doctors and nurses. The results will be useful to develop improved patient's clothing. Based on the results, the following suggestions for improved patient's clothing are made. 1. Gender differentiation and a greater variety of size codes are required for better fit. 2. Depending on various treatments, different functional design features have to be applied. 3. Aesthetic needs should be satisfied for the psychological comfort of patients. 4. Materials should be selected considering required physical properties such as washing duration, dimensional stability and contaminant prevention.

This study examines the prati fashion style. prati fashion refers to a practical fashion, the most sought-after trend and newest fashion concept. This trend emerged as a response to the trio of minimalism, the recent economic downturn and the modern life style, and has led to powerful fashion lines and items. Therefore, this study is to understand and analyze the prati fashion style, with its focus on the 2010 modern fashion collection that embodied functional, economic, and minimal styles. First, the functional style realized by new materials provides comfort and allows multi-style changes. Second, the minimal style adds detailed changes to minimal silhouettes. Finally the economic style means easy to wear and easy to match items at affordable prices. The analyses stated above found that the prati fashion brought about a new paradigm to society, and influenced social, cultural and economic aspects of our daily life. It also helped find solutions to economic problems of this era. Drawing global attention, the prati fashion has functional, design and economic values, and thereby influences the shift of market paradigm.

This paper describes design, implementation and functional test of on-board flight analog video system. Video system is the part of the telemetry system as a means of providing flight vehicle's image data. Adopting analog video transmission technique, we could design and test the system in a short time and implement the prototype model with simpler circuits. As results of the functional test, we have made the verification and validation of two cameras' switching in time, and frequency modulation and demodulation of NTSC color signals successfully.

Construction is a labor-intensive industry that heavily relies on skilled construction workers. However, the aging of the workforce is rapidly growing, and the shortage of skilled workers is intensifying. The application of construction robotics technology can solve the problem of workforce shortage and guarantee construction productivity, safety, and quality improvement. This study presents a framework of the functional analysis for construction processes and work tasks that classifies and analyzes processes and work tasks for construction robotics design. The framework presents the functional analysis process, which analyzes workers' attributes and identifies functions of construction robotics.

When we use various multimedia programs such as 3D-game, visual conference, dial-pad phone by internet service, we make use of headset generally. As internet system is magnified more and more, a demand of headset will be increasing continuously. Because microphone was fixed by headset, it has many inconveniences for using headset. For these reasons, new concept headset is needed nowadays. Main idea of development of headset is very the automatic operation system of microphone. There are many process variables in appling new technology to the conventional headset. They can be solved by using axiomatic approach method which is very useful design method for designing new products. Its main character is scientific and analytical. The goal of this research is to design and manufacture a new headset model with axiomatic design method. In this paper, a new concept headset was presented by mapping the relation between functional requirements and design parameters.

In this paper, we introduce an integrated SoC front-end design & verification environment which can be practically used in the embedded 32-bit processor-core SoC VLSI design. Our introduced SoC design & verification environment integrates two most important flows, such as the RTL power estimation and code coverage analysis, with the functional verification (chip validation) flow which is used in the conventional simulation-based design. For this, we developed two simulation-based inhouse tools, RTL power estimator and code coverage analyzer, and used them to adopt them to our RTL design and to increase the design quality of that. Our integrated design environment also includes basic design and verification flows such as the gate-level functional verification with back annotation information and test vector capture & replay environment.

Design VE (Value Engineering) has been basic design and implementation design separately, but due to the recent change in guidelines, it is changing to implement only once in the implementation design stage. However, in the implementation design stage, construction costs, plans, and specifications based on the volume details are almost completed. Therefore, it is effective to perform the function analysis step after identifying information analysis and key issues through CostModeling based on functional center for the selected target in the process of implementing the VE performance procedure.
