Many engineering polymer is suitable for Crack Layer theory (CL). According to this theory, polymer have different size and shape of process zone (PZ) and in the case of high density polyethylene (HDPE), crack propagates in a d discontinuous manner. In this article, slow crack growth was simulated by microsoft visual C++ 2010 on the grade of HDPE with single edge notched bar (SENT) specimen. In addition, the effects of the stress ratio (R-ratio) that is defined as the ratio of minimum and maximum stress of loading, fracture energy, and draw stress parameter were studied. These parameters have clear tendency and the program has view which appropriate for many other polymers just by turning some parameters into proper parameters.

코로나 19 장기화로 인해 체온 체크는 필수요소로 다중 시설 이용시에는 열화상 카메라를 지나쳐야 만이 시설 이용이 가능하다. 열화상 카메라는 바이러스 확산 방지 예방의 목적성을 충족하지만 여러 명이 지나가는 화면 속 뒷사람이 나를 쳐다본다는 불편함, 몸의 실루엣이 드러나 수치심을 유발하는 등의 새로운 문제를 야기하게 되었다. 따라서 우리는 체온 체크를 하면서도 사생활을 보호하고 수치심을 예방할 수 있는 해결책으로써 미디어아트를 활용하였다. 열 화상 카메라 앞에서 미디어아트로 표현된 내모습을 발견하고 상호작용하며 유쾌한 사용자 경험을 제공하고자 한다.

(Background and Purpose) Community spaces for local community members can be classified as a social infrastructure that revitalizes the community. In addition, mixed-use facilities have become a general trend as an efficient alternative to meet the diverse needs of local residents, high land costs, and the cost problems accompanying the creation of a space. The mixed-use community spaces are also a feature that reflects the current situation facing modern architecture; it is inevitable to accept various programs through architecture beyond restricted land use and the need for cost efficiency to realize diverse needs of the local community members and to establish a local identity. Under this social background, this study attempted to examine the meaning through case studies by deriving the characteristics of space utilization to revitalize the local community and by categorizing the mixed-use facility aspect of local community spaces. (Method) It derived the utilization characteristics of local community spaces through previous studies and examined the actual situation of mixed-use facility aspects of local community spaces through case analysis. (Results) The community spaces for local residents are essential for maintaining and revitalizing the local community; they share the characteristics with public spaces. Based on this, six characteristics, such as locality, singularity, accessibility, commonality, diversity, and safety, were derived for the case analysis of community spaces to revitalize the local community. The local community spaces could be categorized into three types: centered on public administrative agencies, centered on school facilities, and centered on cultural amenities by the main function of individual community spaces based on regional characteristics. As a result of the case analysis, it was found that the main function of the space was selected based on the needs of the local residents to revitalize the local community, and the community spaces were built focusing on the selected specific function. The tangible benefits of mixed-use community spaces have been shown in various forms for the revitalization of the local community, from solving chronic complaints within the local community to working on harmony by operating various programs for local residents. (Conclusions) Through this study, it was confirmed that such spaces could contribute to revitalizing the local community, which was the original purpose of creating a community space when a complexity type suitable for each region was selected. Space was created according to the type for creating the community space to establish the local identity and revitalize the community. In particular, considering that the mixed-use aspect of community spaces has emerged prominently in the last 10 years, and the government policy promotes building various types of community spaces through mixed-use facilities, a further in-depth study on the mixed-use type of community spaces may be needed.

(Background and Purpose) The difference between urban regeneration projects and general redevelopment / reconstruction projects is that it seeks to revitalize urban spaces and improve the quality of life for local residents through the use of local cultural resources. In particular, the purpose of this study was to present the spatial activation elements required for revitalizing the local community, which is the purpose of urban regeneration new deal project, and creating a space for sustainable regional development under the recognition that the cultural urban regeneration is placemaking through the use of local cultural resources, which is a feature of the urban regeneration new deal project that has been in full scale since 2017, is a cultural urban regeneration based on the place attachment shared by local residents. (Method) It tries to understand the concept of place attachment which are the basis theory of placemaking through the use of cultural resources, and derive elements forming place attachment by reviewing previous studies, based on which six general neighborhood project sites were selected and analyzed among urban regeneration new deal projects in Ulsan Metropolitan City. (Results) The urban regeneration new deal projects are implemented in areas that have been assessed as declining areas according to statutory indicators based on legislation, which is based on the restoration of urban competitiveness by revitalizing urban functions, and the revitalization of local communities through job creation, not just improving the residential environment. This shows that the urban regeneration new deal projects are in line with the cultural urban regeneration projects which aim for cultural regeneration and revitalization of a region through place-based culture. The placemaking is based on a sense of place that is an experienced memory shared by residents of the local community. This paper derives locality, shareability, homing, accessibility and sustainability as spatial analysis factors created through placemaking based on the sense of place, considering factors that form place attachment and elements of space utilization in local communities based on the evolutionary psychology perspective. (Conclusions) The urban regeneration new deal project sites looked through the cases in Ulsan Metropolitan City have in common in making efforts to secure the local identity through the use of local cultural resources and to secure the homing property of collecting and accumulating the memories experienced by the residents. However, the shareability or accessibility of local cultural assets should be examined in more detail as it is important to establish relationships with users of various classes. Furthermore, the sustainability of various places created through the urban regeneration new deal projects in the future requires continuous attention and research as it should reflect changes over time.
