The purpose of this study is to present types of design concept based on the specificity of landscape design, and to derive a theoretical framework for the landscape design concepts by analyzing the design concepts appearing in urban park design competitions. Through literature review, five types of landscape design concepts were categorized into value and vision, analysis and interpretation, form and structure, program and element, and process and operation. Using this framework, the design concepts shown in 96 works submitted to 18 domestic and overseas urban park design competitions were analyzed. The results of the analysis are summarized as follows. First, due to the complexity of contemporary urban parks, design concepts are presented as mixtures of main concepts and secondary concepts in multiple layers. Second, it was identified that design concepts of 'form and structure' were used the most in urban park designs, followed by the 'program and element' concepts. The 'value and vision' and 'analysis and interpretive' concepts are introduced as third and fourth. Third, the reason that the 'form and structure' concept is widely used as main and secondary concepts is judged to be because the form of a space, which is the key result of the design, has an important influence on the identity of the design. Fourth, the reason that the 'program and element' concept type is widely introduced is that urban park design has a stronger planning aspect to produce programs during the design process, compared with other design fields where programs are usually given in advance. Lastly, it is difficult to see that the properties of the site solely affect the type of design concept, because a design concept is the result of a complex and creative process in which a designer subjectively interprets the objective characteristics of the site and project, and given design guidelines can affect the type of design concept.

Nowadays, the various kind of software packages that support content creation consumed in touch-type terminals as an application have come into the market. These softwares have a different style of user task compare to existing user task. The reason why difference style has been appeared for now is because interaction timing has a important role of both content creation and consumption. For this reason, in this paper, we propose a software UI design framework for content creation using MB-UID and UCD model based on task modeling. The proposed framework is made up of five steps: business rule model, creation role model, creation flow model, creation action model, presentation model. Through this framework, we handle the interaction between a content creator and software user interface at the content creation phase. At the same time, we consider a possible interaction type which can occur by consumers at the consumption phase in advance.

In a MOSFET multivibrator, the gate do not hold into a constant clamp voltage during a conduction period. The analysis of the operation and the 43sign of a MOSFET multivibrator circuit are much more discult than that using a bipolar transistor and a electron tube because of above reason. And therefore, in the designing procedures of the MOSFET monostable multivibrator of this paper, a graphical method is adopted in order to analyze and design easily. The voltage gain curves of the both FETs are drawn using a parameter the voltage Vc across the coupling condenser, and the curves are utilized to investigate the voltages of the drains and the gates and determine the gate bias voltage. The diagram gives also important informations for the design of the multivibrator.

Power steering of a car is used to reduce driver's handle control power. It is usually operated by oil pressure of engine power. However, electrically power steering (EPS) is used recently instead of oil pressure type for environmental and economical reason. This paper presents structure design and characteristics analysis of SRM for EPS application.

The architecture of microprocessor for a embedded system should be one that can perform more tasks with fewer instruction codes. The machine codes that high-level language compiler produces are mainly composed of specific ones, and codes that have small size are more frequently used. Extended Instruction Set Architecture (EISC) was proposed for that reason. We have designed pipe-line system for 64 bit EISC microprocessor. function level simulator was made for verification of design and instruction set architecture was also verified by that simulator. The behavioral function of synthesized logic was verified by comparison with the results of cycle-based simulator.

During process design or process optimization, it is quite common for experimenters to find optimum operating conditions for several responses simultaneously. The traditional multiresponse surfaces optimization methods do not consider the uncertain relationship among these responses sufficiently. For this reason, the authors propose an optimization method based on evidential reasoning theory by Dempster and Shafer. By maximizing the basic probability assignment function, which indicates the degree of belief that certain operating condition is the solution of this multiresponse surfaces optimization problem, the desirable operating condition can be found.

On the tunnel design, 3D model substituted for 2D model because of economic reason and time shortage. It is applied Load Distribution Factor, which is compared of displacement of tunnel crown, generally 50-25-25, 40-30-30 are used for tunnel design. Logicality about used Load Distribution Factor will investigated

A robot system in most industries has a complicated structure, which includes electric and electronic components, and mechanical parts. For this reason, building a robot system also has a very complicated design and maintenance processes. Especially to predict or assess the system's maintainability and safety is important for both designer and operator before it's production or installation of the system. This paper presents an application methodology of FMECA focused on safety in design of a robot system with point of view of reliability engineering.

In this paper, we have researched a Automatic Power Factor Correction and THD reduction System for the multiple connection of CFL. Also in this paper, the power factor has been researched for the design of CFL, found the reason why the power factor is low and THD is too high. This paper has designed the PFC System for the multiple connection of CFL, and then we have increased the power factor and reduced the total harmonic distortion, by implementing them.

In this paper are described design of hardware and GUI(Graphical User Interface) for a PC based Weighting System. Conventional Weighting System is adapted microprocessor system for measuring and controlling. This system should have big memory for the management of measured data and is difficult to operate. For such reason a new Weighting System based on PC is proposed. In this contribution is handled these problems.
