With the continuation of the pandemic environment, digital transformation is being applied in various fields of the fashion industry. Augmented reality technology is a form of overlapping virtual images on the real world, and as online shopping expands in non-face-to-face environments, the use of augmented reality technology in fashion and beauty fields is affecting consumer satisfaction and sales growth. In this study, the characteristics of augmented reality contents used in the fashion industry following digital transformation were extended to the fields of clothing, accessories, virtual fashion stores, and AR fashion shows to analyze the case characteristics of augmented reality. Augmented reality technology in the fashion industry focuses on promoting clothing and accessory products through SNS or homepage through marketing activities. It is raising positive values such as raising awareness. The range of types of augmented reality used in the future digital fashion environment will continue to expand, and by deriving the usage characteristics of augmented reality technology, it is intended to contribute to presenting a future vision of the fashion industry.

Urban residential area, one of the main subjects of urban and architectural studies, can be analyzed accurately and rapidly with CIS. (Geographic Information System) And the applications of GIS in urban studies are too macro to be explained in architectural terms and the ones in architectural studies are not so much active rather be used as a secondary means. So the studies in urban-architectural scale are very useful in many ways. This study explores urban-architectural possibilities of analytic capabilities of GIS through the analysis of spatial characteristics of residential area in terms of land price according to parcel attributes. It is found, firstly, that the parcel attributes have relations with land price and its distribution patterns. Secondly, it is verified that the visualization capability of GIS can be a very useful method of analysis through user-interface effects in urban-architectural scaled analysis.

In order to enhance their own customer satisfaction index that is one of the top level managerial performance indices, Internet communication service providers endeavor onto establishing a total quality management system. Specifically, it is under discussion that some critical Internet communication network quality characteristics closely related to customer satisfaction index should be controlled aiming to this managerial goal. This paper presents an application scheme of I-MR control charts for monitoring Internet communication network quality characteristics. This statistical quality control scheme generates a signal to practitioners when it detects the network quality characteristics out-of control. It is designed based on; 1) individual measurements; and 2) moving ranges between two consecutive individual measurements collected with a constant time interval. Empirical analyses are illustrated to estimate the expected quality improvement ratios that can be realized with the application scheme proposed in this paper. Assuming that the assignable causes can be revealed and eradicated, regarding two Internet communication services A, B, seven network quality characteristics for each service, eleven distinct measuring spots for each network quality characteristic, the expected quality improvement ratios are calculated with which the effect of the application scheme is evaluated. Results show the ranges of the expected quality improvement ratios; 1) Service A, (1) mean (0.31%-11.44%), (2) standard deviation (9.82%-71.10%): 2) Service B, (1) mean (0.29%-17.64%), (2) standard deviation (8.05%-60.59%). Hence, It is anticipated that the I-MR control charts based application scheme can be effective not only to improving the mean and dispersion of the network quality characteristics concerned but also to maintaining the network quality characteristics in-control consequently.

This paper presents the engineering property of light weight soil made of soil mixed with recycled stylofoam and stabilizer. Recycled stylofoam beads is able to use by lightweight fill materials because it is light, adiabatic, and effective for vibration interception. Especially, recycled stylofoam beads is easy to supply because stylofoam have been recycle item in 1996. In this study, physical and geotechnical properties of the light weight mixed soil(weathered granite soil mixed with Stylofoam Beads) were analyzed by laboratory experiments to examine its suitability for backfill materials. Laboratory tests were performed to evaluated strength, bearing capacity, weight, permeability, microphotograph analysis with variation of mixing ratio. Based on the results, it is concluded that the use of recycled stylofoam beads is acceptable lightweight fill.

In the mix proportion of shotcrete, it was analyzed as required in terms of eco-friendly technology to take advantage of the screenings. Screenings of recycling can be a solution in order to overcome the quality degradation due to the recent lack of good quality sand as well as the utilization of waste materials. Five regional screening and screening replaced fine aggregates for physical characteristics were analyzed to evaluate the usability screenings as shotcrete's combined aggregate. It was analyzed the effect of particle size distribution in the combined aggregate for shotcrete and maximum replacement was estimated according to the type of screenings.

In case of recycled fine aggregate, density and absorption ratio is lower than natural one, so it is used to lower value added products and it is limited its usage. It is reported that Compressive and tensile strength of recycled concrete is more deteriorate and shrinkage properties is very deteriorate because high absorption of recycled fine aggregate. Accordingly, in this study, it is develop that dry manufacturing system composed specific gravity separator of high-speed rotation impact type, reclaimer of minuteness fine aggregate and evaluate that shrinkage properties of recycled concrete using recycled fine aggregate at producing this system. Hereafter, it is present that fundamental data to practical use recycled fine aggregate.

The purposes of this research are to empirically examine (1) the impact of application of IT in IT industry which is the main engine for creative economy, (2) the relationship between application of IT and corporate strategy, and (3) the influence of corporate strategy on application of IT and employment. To achieve the purpose of research, we conducted a survey on 187 CIOs in october 2013. Research findings confirm that application of IT provides competitive advantages such as efficiency, threat, functionality, attack, and integration and these traits of IT significantly contribute to employment. And research results show that the moderating effects of corporate strategy on the relationship between application of IT and employment are different depending upon the type of corporate strategy. Thus firms in IT industry should consider traits of IT more seriously when they establish corporate strategy.

In this study, the engineering charateristics of recycled cold asphalt mixtures using waste glass and red mud were examined as part of the development of low carbon road pavement materials using large amounts of waste. It also examined the satisfaction of the performance criteria specified in the standard. As a result of the study, it was found that RCA using waste glass were not met standard of GR since strain resistance reduced. Therefore, it has been shown that improvements in the composition of the mixture are needed. It has also been shown to significantly improve the performance of the mixture when adding red mud. In addition, it was found that the quality standards for stability, flow value, indirect tensile strength and tensile strength ratio as specified by GR are satisfied.
