A possibility of using waste plastics as a source of secondary fuel in blast furnace has been of recent interest. The success of this process, however, will be critically dependent upon the optimization of operating systems. for instance, the supply of waste plastics must be reliable as well as economically attractive compared with conventional secondary fuels such as heavy oil, natural gas and pulverized coal. In this work, we put special importance on the improvement of the combustibility of waste plastics as a way to enhance energy efficiency in blast furnace. As experimental variables to approach this target, the effects of plastic particle size, blast temperature, and the level of oxygen enrichment were investigated using a custom-made blast model designed to simulate a real furnace. Lastly, the combustion efficiency of the mixture of waste plastics and pulverized coal was tested. The observations made from these experiments led us to the conclusion that with the increase of both blast temperature and the level of oxygen enrichment, and with the decrease of particle size, the combustibility of waste PE could be improved at a given distance from tuyere. Also it was found that the efficiency of coal combustion decreased with the addition of plastics; however, the combustion efficiency of mixture could be comparable at longer distance from tuyere.

The result of this study is on textile expressed in the costume of the Kazakh tribe, Kirgiz tribe, Tajik tribe. Basically the material of costume is fur, cotton flannel, felt, silk, cotton outwear, velvet cloth and beads, silver, earing, bracelet is used frequently. The tribes did embroider on the shoes, made of sheepskin or calfskin and collar, belt, button, pocket with the sketch of national trait. Eventually their cultures of costume seem to be very similar because of the resemblances in circumstance of nature, religion, custom of life but definitely they show conservatism in itself and independent culture. In the basic structure of traditional costume by races, there is no big difference. Then, in men, the trousers and the shirts of tunic type become the basic with the style which is convenient to act. And, to wear vest, or jacket, or chaban, over it makes a little difference. In women also, same structure shows with the form to wear vest or outwear, on the basis of one piece. But, in a small hat, head wear, color contrast, and decoration element etc., strict difference is showing. After all, they show very similar clothing life culture basically in natural environment, religion, and life habit etc., But, the discrimination is made in the detailed side. So, it can be said that they show the conservative nature of nationalities, and have preserved the unique identity of their own culture.

With the increasing popularization of low-priced luxury markets, maintaining the genuine values of luxury has become crucial for luxury fashion brands to attract customers who want exclusivity and rarity. The world-leading luxury fashion houses have employed a variety of experiential marketing strategies like special order product strategies and mobile SNS promotion strategies, yet little research exists on there the strategies actually positively impact brand luxury images and customer attitudes towards the brand. This study empirically analyzed the effects of customer experience of special order products on perceived brand luxury and brand relationship. Furthermore, the study also tested relationships among perceived brand luxury, brand relationship, and brand loyalty. A survey was conducted with Korean female consumers who had purchase experiences of special order products from the brands. We analyzed the data of MTO-experienced respondents due to the lack of respondents who had experienced custom-made product services. The result indicates the significant effect of experience of MTO on brand relationship; however, we found only a partial support for the effect of MTO on brand luxury. Likewise, we found a partial support for the effect of mobile SNS promotion strategies on perceived brand luxury versus full support for the effect on brand relationship.

The selection rate of tree burials (TB) is still low in spite of increasing concerns about TB and government's efforts to increase TB participation. It is necessary to understand the factors affecting TB selection. This study investigated the relationship between major variables (attitude: ATT; subjective norm: SN; perceived behavioral control: PBC) of Ajzen's theory of planned behavior (TPB), additional variable (custom: CUST), and intention to select TB by using structural equation modelling (SEM). Samples were selected from Gwang-ju citizens using proportionate stratified sampling (PST) by region during September of 2011. Four hundred and twelve responses were used for data analysis. The model showed fair goodness of fit. All four variables (ATT, SN, PBC, CUST) influenced intention to select TB. The four variables explained 53.0% of intention to select TB. SN(${\beta}$=0.459) was the most predictive variable on the intention, followed by ATT(${\beta}$=0.247), PBC(${\beta}$=0.152), and CUST(${\beta}$=0.102) in decreasing order. The results were discussed and some suggestions to increase the intention of tree burial selection were made.

The aim of this study was to evaluate the fixation effect by connecting impression copings and to compare the three types of impression trays which were used in open tray impression technique. Experimental groups used 3 types of impression trays which are custom tray, plastic metal combination tray and polycarbonate stock tray. These three groups were subdivided into splinted and non-splinted impression copings group. The total number of experimental groups was six. 10 specimens were made for each group. We used 1-screw test, observing the specimen on which only one side abutment of reference framework was fixated with 20 Ncm. The gap between implant analogue and abutment of the other side was observed by stereo microscope. It was measured at 6 points in each specimen. Measuring value was selected when same result was revealed 3 times. Recorded data were statistically analyzed. Whether impression copings were splinted or not, there was no significant difference among custom tray group, plastic metal combination tray group, and polycarbonate stock tray group. Significant statistical difference in vertical fit discrepancy was found between splinted and non-splinted impression copings group with custom tray, plastic metal combination tray and polycarbonate stock tray (p<0.05).

Wrist braces are being used for patients with wrist trauma. Recently, many studies have been conducted to manufacture custom wrist braces using 3D printing technology. Such 3D printing customized orthosis has the advantage of reflecting various factors such as reflecting different shapes for each individual and securing breathability. In this paper, the stress on the orthosis by the number and position of Velcro bands that should be considered when manufacturing a 3D printing custom wrist brace was analyzed. For customized orthosis, 3D modeling of the bone and skin regions was performed using an automatic design software (Reconeasy 3D, Seeann Solution) based on CT images. Based on the 3D skin area, a wrist orthosis design was applied to suit each treatment purpose. And, for the elasticity of the brace, a wrist brace was manufactured with an FDM-type 3D printer using TPU material. To evaluate the effectiveness according to the number and position of the Velcro band of the custom 3D printed wrist brace, the stress distribution of the brace was analyzed by the finite element method (FEM). Through the finite element analysis of the wrist orthosis performed in this study, the stress distribution of the orthosis was confirmed, and the number and position of the orthosis production and Velcro bands could be confirmed. These experimental results will help provide quality treatment to patients.

Local resources can be employed as an original resource for local revitalization. This study has investigated the local resource, and then categorized these to suggest the implication available to the industrialization. Local resources were classified into 5 categories(with 25 subcategories), including remains and ruins, ethnic custom, manners and customs, people, traditional food and the principal product, and the natural ecology environment. Three phases were carried out in this study. We made lists of local resources and analyzed applicable resources among the lists. Also, we selected the target resources for the survey in Gimpo, and also analyzed the application for industrialization. Of all these resources, 560 cases were first investigated, then 51 local resources were in-depth analyzed. Based on this result, the application plan was investigated, dividing the central resources and the connection resources.

It has applied the design method of face to face dimension, an MC (Modular Coordination) design method, at design steps of an apartment house for standardization of architecture. But It has been still using center line size. A construction limit isn't specific on these center line size, and dead space occurs with excessive gaps as size matching isn't performed well between structural sieve and parts. And above all, measurement before construction isn't to expect standardization, and to increase custom-made furniture. We investigate manufacture of a preferential domestic system kitchen and construction state, and we derive from a problem in viewpoints of standardization for this. And we utilized a reference plane, and we present construction document and design plan in order to solve these problems. And we analyze an effect got by application of the assembly basis aspect that we presented, and we can raise efficiency of standardization of housing and construction industry, and we light ultimately up.
