This study is as a part of the new disposal and recycling plans of heat-resource waste of Daegu dyeing, industrial center we tried to examine applicable possibility of crushed thing(waste aggregate) as aggregates for mortar and concrete. To examine applicable possibility of waste aggregate as a lightweight-aggregate for concrete and mortar, we carried this study by mainly property examination of concrete according to replacement ratio of waste aggregate. We carried slump, unit weight, compressive strength and bending strength test according to replacement ratio of waste aggregate. As the result of that, if we use waste aggregate, lightweight of concrete and mortar will be possible. Specially it shows a strength improvement effect of cement hardening according to using this so it is judged that applicable possibility as aggregate for concrete and mortar is very excellent.

In this paper, machining characteristics of glass for HDD media are researched. Nowadays HDD media are used globally as a data storage device. In generally, it is machined by the lapping. But the lapping process time is long and the productivity is low. In this reason, 1 examined the possibility of ELID grinding of glass fur HDD media. If the machining process of HDD media can be changed to ELID grinding, a product cost will be largely saved. The machines used in this experiment were a special rotary type grinder and a normal rotary grinder. The one has an air bearing spindle, the other has not. Experimental results show the possibility of highly efficient grinding and mirror surface can be achieved by the ELID grinding.

The rectus abdominis myocutaneous flap is frequently used in the field of plastic and reconstructive surgery such as breast reconstruction and as a donor of free tissue transfer. Major problems with this flap is bulkiness, the possibility of postoperative abdominal herniation and muscle weakness following the removal of the rectus abdominis muscle. We used paraumbilical perforator based skin flap fed by a muscle perforator from the deep inferior epigastric artery, with no or little muscle and fatty tissue, in three patients for the resurfacing of relatively wide and thin defects. This technique has all of the advantages of the conventional rectus abdominis myocutaneous flap with decreased possibility of postoperative abdominal herniation or muscle weakness. Another challenging merit is possibility of skin flap thinning.

Defect region segmentation of TFT-LCD images is performed by combining defect pixels detected by a defect detection method into defect region, or by using morphological operations to segment defect region. Therefore, the result of segmentation of the defect region is highly dependent on the defect detection result. In this paper, we propose a method which segments defect regions sequentially according to the possibility of being included in defect regions in TFT-LCD images. The proposed method repeats the process of detecting a seed using the median value and the median absolute deviation of the image, and segments the defect region using the seeded region growing method. We confirmed the superiority of the proposed method to segment defect regions using pseudo-images and real TFT-LCD images.

The development of farm villages into ecovillages aims at creating an alternative that reconciles the environment with economy, the two practical issues faced by farm villages. Recently various projects are being carried out to resolve the weak competitiveness of farm villages and to induce environment-friendly development, but they have basic limitations in improving farm villages. Thus, the present study purposed to examine the possibility of transforming farm villages into ecovillages as an alternative for solving these problems more effectively. Thus this study selected Sori Village to experiment the possibility of transforming farm villages into ecovillages, presented the process of planning using environmental planning indicators, and verified its validity through designing an experimental model.

The development of information & communication technology in 21st century along with the mass media In 20th century, the influence of state-of-art culture in our society rapidly increased in these days. This state-of-art culture makes the world becomes single-channeled by network, and there is a big change not only in human life but also in concept and understand for art and space. The development of digital paradigm and media technology is exerting a strong influence on the Ubiquitous computing environment that is being drawn great interest. The ubiquitous is concerned as expansion of media art, and the interactive art which is part of media art has the similarity with the ubiquitous computing environment. In this study, the possibility of connection between the territory of ubiquitous environment which is recently focused and has strong interrelation feature, and the territory of interacting will be examined. Furthermore, possibility of new space design work through seeking the possibility of connection between two territories will be estimated.

The goal of this study is the derivation of priority for business in the areas of green energy technologies. In this paper, we calculated the importance weights of impact factors using the AHP (Analytic Hierarchy Process) method in order to derivation of priority to the green energy technologies business. AHP is a useful method for evaluating multi-criteria decision making problems. To apply the AHP method, specialists for the assessment have been identified by using the concept of 'plan, do, see' and the decision-making hierarchy was established. We selected 5 criteria and 16 sub-criteria for impact factors by brainstorming. According to the result in this study, the most important impact factor is the possibility of commercialization, the second is the possibility of developing the fundamental technology, and the third is the possibility of convergence technology.

This study analyzes the new possibility of design through the research for the expression of cladding design architectural materials, and applies to connection with creative design concept. In these modern days, architectural materials became the subject of expression as itself thanks to the development of new technology and materials. The physical properties of materials and their beauty value made possible the variety and possibility of expression in space design. The expressional properties of materials can lead mutual communication between commodity and brand by association, presenting brand image and the distinction of its value. Therefore, the trends of designed material expression in space design according to modern aspect can offer the possibility of material space design for ahead. This study suggest an alternative idea for revitalizing design by materials.

The article contains an introduction of possibility of applying Multi-Attribute Utility Theory(MAUT) for priority setting of R&D projects. MAUT is compared with AHP, which is widely used recently. These two techuiques are applied to set priorities of R&D projects In a Government-funded Research Institute. Six criteria are chosen from consultation with decision makers. They are composed of 1) validity as representative projects, 2) possibility of resource mobilization, 3) spillover effect of developed technologies, 4) possibility of success, 5) scope of participation and 6) clarity of research goal. To set priorities of R&D projects, SMART(Simple MultiAttribute Rating Technique) and DVM(Difference Value Measurement) out of many MAUT methods are used to design the utility function and to determine the weights among criteria. The aggregation model is additive on the assumption the criteria are independent. AHP executes pairwise comparisons for criteria and alternatives. From the results of the case study, the results and theoretical characteristics are compared.
