The urban renewal type redevelopment project is a project to improve the urban environment for the recovery of urban functions and revitalization of commercial districts in commercial and industrial areas. Urban regeneration projects are not progressing smoothly. The urban renewal type is not so for landowners, who require a high level of professional knowledge and experience to carry out smooth projects. In addition, the core part of business conflicts can be seen as the problem of management and disposal methods. Therefore, as landowners, etc. become the actual subjects, the public will take charge of project execution, but all development gains and losses will be attributed to the owner of the land, etc.

A 5.0-inch plastic TFT-LCD with the resolution of $400{\times}3{\times}300$ lines (120ppi) was developed. The device is a transmissive type with the transparent PES plastic substrates. The PES films with one side barrier coating were used for the device. In order to produce the high resolution display device, the alignments between all the layers for the TFT and CF are essential. The fundamental shrinkage effect and the thermal expansion behavior of the plastic substrates with and without the barrier coatings were studied. The proper annealing processes followed by immediate second bar-rier coating processes provide the optimal alignment between all the layers of the TFT and CF..

Therefore, it is necessary to study Podaegi to inform Korea's traditional parenting culture product. In this research, 230 images of Podaegi were collected from paintings, photographs, postcards, films and artifacts from the late 18th century to 2000. The period of study was divided into three phases from the late Joseon Dynasty to before the opening of the port, from the opening of the port to before the liberation, and from the liberation to 2000. Types of Podaegi were categorized according to its shape and how to use. Transition process of Podaegi was examined. Podaegis were categorized into band type, blanket type, combination type, cheone type, modern type, and so on. From the late Joseon Dynasty to before the pre-openings, band type was used. From the opening of the port to liberation, all types of Podaegi appeared. Since the liberation, the use of band and blanket type has gradually decreased. Modern types have been the most popular since the 1960s. Materials of Podaegi became varied and Podaegi became a fashion-item. Later, modern Podaegi became the representative form of Korean traditional Podaegi.

Recently, interest of consumers in home furnishing products has increased steadily because of the increased time spent at home due to COVID-19. Among them, carpets made of various materials and technologies are becoming popular interior item. Academic and industrial sectors agreed on the need to produce premium design carpets. Prior research on carpet design was mostly focused on patterns, history, with insufficient investigations on the type. Therefore, the purpose of this study was to provide basic data to develop premium design carpets by analyzing their expression types. To analyze expression types, this study covered about 400 design carpets surveyed on the websites of eight major carpet companies from January 2021 to March 2021. Based on the analysis results, the five expression types of are as follows. Firstly, the expression type was expressed in various atypical forms that was deviated from the formal form. Secondly, it was a type that improves visual and tactile effects through a variety of 3-D textures. Thirdly, it was a type of diversification of motifs, which was based on the works of artists and designers in various fields. Fourthly, it was a type that combines two or more different materials and techniques. Finally, it was a modular type that can be applied in various ways to various spaces. Based on the analysis results of this study, it is hoped that the data will be helpful to produce premium design carpets in Korea.

Purpose - The purpose of this study is to examine whether trading volume amplifies the extent to which lottery-type stocks are overpriced, and whether economic sentiment index explains time-variation in the magnitude of the volume amplification effect. Design/methodology/approach - We examine monthly returns on 5x5 monthly bivariate portfolios formed by lottery characteristics (measured by maximum daily return) and trading volume. In addition, we perform time-series regression tests to examine how the volume amplification effect changes in high and low economic sentiment periods, after controlling for Fama-French three factors. Findings - Our bivariate portfolio analysis shows that the overpricing of lottery-type stocks are mostly pronounced among high trading volume stocks. In contrast, for low trading volume stocks, overpricing of lottery-type stocks appears to vanish. Furthermore, the amplification effect of trading volume on overpricing of lottery-type stock is concentrated in high economic sentiment periods. Research implications or Originality - This study is the first attempt to examine whether trading volume drives lottery-type stocks' overpricing in the Korean stock market. Furthermore, our analysis unveils the time-varying nature of volume amplification effect. The results suggest that trading volume might play a important hidden role in asset pricing, opening a new line of researches in the future.
