South Korea, a rapidly ageing country, faces increasing dementia rate as the incidence of dementia increases with ageing. Service design is an effective method to develop dementia service by visualizing and specifying intangible forms of service. The Design Council in the U.K. carried out dementia solution projects such as 'living with dementia' in 2011 and 'transform aging' in 2016, introducing successful services and innovative products. Seeking useful implications, this paper explores the concept and method of service design focusing on the U.K. cases. To suggest solutions on dementia, effective strategies should be set up on the basis of service design, which embodies various stake holders' cooperation and partnership.

In the fabrication of dry adhesive structure, increasing contact-points or contact-area is the primary goal because the adhesive force grows in proportion to the contact-area. The simplest way to extend the contact surface is the fabrication by using soft materials. However, the column-array structure could confront the matting phenomenon which columns are stuck together. Therefore, we need a novel design to reduce the effective stiffness with adequate stiff materials like a gecko's setae. In this study, we propose a novel design for the dry adhesive structure. Moreover, we analyzed whether the adhesive structure conforms the rough surface sufficiently through finite element method adopted the non-bonding interaction as the body force. Also, we fabricated the novel structures via UV lithography and some techniques. In addition, we examined the adhesive force of the novel structures.

Proposed in this paper is a model-bated AFA (automatic feedrate-adjustment) method for maintaining smooth cutting-loads (i.e., cutting-force) during 2D-profile milling. Before the cutting-force model was established, some assumptions were verified through a series of preliminary cutting experiments (The results found that the curving-force was independent of the cutting speed and the cutting action at the cutter bosom). From the data obtained during the main cutting experiments, a “chip-load/cutting-force model”representing the cutting-force as a function of the chip-load (i.e., effective cutting-depth) and a feedrate is proposed. Based on the model. an AFA scheme for maintaining smooth cutting-force by adjusting the feedrate (i.e., F-code) according to the changes in chip-load was proposed. To check the validity of the proposed AFA scheme. another set of cutting experiments was conducted by using feedrate-adjusted NC-data while monitoring the actual machining processes using an accelerometer. The experimental results showed that the proposed AFA-scheme was quite effective.

There has been a study about the effective multimedia education using a computer following the appearance of a virtual space. Also, there has been an effort to connect the information & communication technology with education. The popular on-line lecture systems are mostly on English lecture sites. However, they just offer the VOD(Video On Demand) services ignoring students' convenience. To improve these week points, we design and implement the multimedia leaching system focusing on an efficient repeat-effect in order that students can control the Media Player by clicking a sentence on a web page. This paper presents the Editor and Player considering students' interest and the effective learning fruits. So users can easily make multimedia materials and use them to improve their English listening skill.

The setting of protective relays, which is critical to the system security, requires a huge volume of data and a lot of repetitive calculations. Since an effective design of a database is essential. The relay setting database must accommodate a variety of protective devices. Also its information can be viewed and updated with easy by humans and by computer programs. This paper describes several existing database designs for power system protection, their advantages and disadvantages. Also this paper develops an effective database for power system protection with their advantages.

The effective length factor of a framed column may be determined by means of the alignment chart procedure. This method is based on many unrealistic assumptions, among which is that all columns have the same stiffness parameter, which is dependent on the length, axial load, and moment of inertia of the column. A new approximate method is developed for the determination of effective length factors for columns in unbraced frames. This method takes into account the effects of inelastic column behaviour, far end conditions of the restraining beams and columns, semi-rigid beam-to-column connections, and differentiated stiffness parameters of columns. This method may be implemented on a microcomputer. A numerical study was carried out to demonstrate the extent to which the involved parameters affect the K factor. The beam-to-column connection stiffness, the stiffness parameter of columns, and the far end conditions of restraining members have a significant effect on the K factor of the column under investigation. The developed method is recommended for design purposes.

In this work, random homogenization analysis for the effective thermal properties of a three-dimensional composite material with unidirectional fibers is presented by combining the equivalent inclusion method with Random Factor Method (RFM). The randomness of the micro-structural morphology and constituent material properties as well as the correlation among these random parameters are completely accounted for, and stochastic effective thermal properties as thermal expansion coefficients as well as their correlation are then sought. Results from the RFM and the Monte-Carlo Method (MCM) are compared. The impact of randomness and correlation of the micro-structural parameters on the random homogenized results is revealed by two methods simultaneously, and some important conclusions are obtained.

Most of designers use applied software of computer programs instead of traditional tools such as brushes, poster colors, etc. for drawing and designing. For example applied software programs for design are applied the workings printing, presentation, movie, animation, character design as well as industrial design. Especially, quality of applied software programs in the field of visual communication design influence on the design results in future. Therefore, many college attempt to invest budget to inhrence the quality of software program in design education. However, effectiveness of investment is lowered due to the professional lack of software knowledge. This study tries to explore how the investment for software program in visual communication design becomes more effective, and to suggest how the order of software program, design curriculum through the affective computer usage in design education will be more useful than now. By comparing and contrasting the different cases in the computer environments of the colleges, this study was processing, the result of this study will contribute to the design education of visual communication.

Teachers must design instruction to meet effective teaching and learning before teaching implementation. The traditional models of instructional design such as Dick and Carey, ADDIE and ASSURE have been widely applied. However, the traditional models of instructional design have limitation in that students fail in deep understanding of subject content because of break down essential goal of the unit small pieces of contents. To solve this problem, Wiggins and McTighe have suggested backward design. Backward design is a method of designing instruction by setting evaluation before choosing activities or content to teach. Therefore, this study explores the effective teaching and learning by analyzing structure of backward design and appling backward design to 'Library and Information Life' subject for information literacy education. Backward design for 'Library and Information Life' subject applies the template which Wiggins and McTighe devised for instructional design.

This study is to explore effective implementation strategies of elective-based curriculum in high schools, and to infer some implications for the improvement of school facilities. For the purpose, this study did three things. First, it tried to find the degree to which students are provided with the courses they want to take for the elective-based curriculum. Second, it explored effective implementation strategies of elective-based curriculum in high schools with the introduction of students' 'pre-application and lottery-allotted system' of high school admission. Third, it tried to infer the changed policy's implications for the improvement of school facilities. As a result of the study, three points are to be emphasized for the future plan and design of high school facilities. First, different school facilities are needed for each school because each school would implement different types of school curricula. Second, schools should be provided with different sized classrooms and different number of classrooms because three different types of students are assigned for each school as a result of new students' allocation policy. Third, new measures should be taken to provide students who are assigned to unwanted schools with opportunities to take courses outside their schools because students assigned by lottery system cannot have so much opportunity as students who are allocated to chosen schools.
