  • Since IFC (Industry Foundation Classes) 4 is based on the representation of 3D elements for an architecture project, and does not define standardized shapes for civil projects such as roads, bridges, and tunnels etc, it has limitations in securing interoperability for exchanging a shape information model for the civil projects. Besides, since road facilities have a linear reference, which is modeled along the center alignment, it is difficult the designers to create a standardized 3D road model. The aim of this study is to configure structure elements and their attribute for a road in the perspective of 3D design for developing a shape information model for the road. To solve these issues, this study analyzes the design documents, which consist of a road design handbook, guide, specifications and standards, and then extract shape elements and their attributes of road structures. Such shape elements are defined as an entity item and we review a hierarchical structure of a road shape defined by a virtual road model. The detailed elements and their attributes can be utilized as a 3D shape information model for constructing BIM (Building Information Modeling) environment for Infrastructures. Besides, it is expected that the suggested items will be utilized as a base data for extending to IFC for a road subdividing the detailed shapes, types and attributes for road projects.

  • This study aims to investigate the changes in the employment structure of occupational groups by job characteristics and analyze the factors influencing wage premiums in local labor markets from 2010 to 2020. This study's analysis involves three primary steps. First, the occupational characteristics data from the Korea Network for Occupations and Workers are subjected to an exploratory factor analysis, and then a non-routine task intensity index is calculated by each occupations. Then, we conduct an exploratory analysis of changes in the distribution of employment by occupation from 2010 to 2020 by combining data from the Population Census with data from the Korean Labor and Income Panel Study to construct individual-level and regional-level data. Thirdly, we employ a hierarchical linear model to examine the individual-level and regional-level factors influencing wage premiums. Since 2010, the proportion of employment in occupations requiring non-routine task has continued to rise and now dominates the metropolitan labor market. Moreover, agglomeration effects resulting from urbanization produce a substantial wage premium for wage workers in occupations requiring non-routine tasks. This study seeks to provide policy implications to mitigate inequality and polarization in local labor markets by empirically analyzing the transition of occupational structure and wage inequality in relation to the local labor market context.

  • This paper describes the result of study on measurement of displacement of structure by means of non-contacting method, close-range digital photogrammetry using digital camera. To apply close-range digital photogrammetry to displacement measurement of structure, correction of lens distortion that interferes geometrical analysis has been carried out and then measuring displacement was performed on load regulated-rahmen. For enhanced applicability of displacement measurement, MIDAS which is a structural analysis program was used for modeling and the result was taken from comparative analysis. As a result of the study, it is showed that close-range digital photogrammetry could supplement several weaknesses of LVDT and cable displacement meter and, especially, economy in the perspective of measuring time could be realized. Close-range digital photogrammetry using digital camera can be applied to the area where requires visual analysis such as 3D modeling of structure, profile replication of measurement of structure as well as measurement of displacement of structure.

  • This study aims to test the spatial mismatch hypothesis by exploring the relationship between income and commuting time in Seoul, Korea. For this purpose, we analyze the commuting times of individuals who commute to Seoul, using the data for the metropolitan household survey. We employed a hierarchial linear model(HLM) to capture the effects of both individual attributes and regional attributes, and their interactions. The results show that the commuting time decreases with household income controlling for the regional attributes, and the effect of income increases with the housing price of the location of a commuter's firm. This implies that the spatial mismatch holds for Seoul as follows: Lower personal income and housing affordablility extend individuals' commuting times, and the destinations' characteristics such as housing type and land use also have impacts on commuting time. These results have some policy implications for achieving social equity in terms of spatial structure of the city.

  • Environmental design is the process of creating and suggesting a new culture retlectmg the spirits and scientific know ledges of an age, so il is important for a designer, who deals environment, to perceive the present trend of science, The goal of this study is to suggest a way to recover the vanishing image in current urban environment from the viewpoint of changing world-view, The process of this study is as follows. 1. According to spatial hierarchy, the role of each space and the importance of each space in correlation with human are considered. 2. The method to undersk, nd the space from the viewpoint of new paradigm and the direction of environmental design's access are suggested. 3. The notion that introduction of semi public space In urban environment is consistent with new paradigm is demonstrated and the semi public space's role of stimulation of urban activity is emphasized. The result of this study shows a possibility that semi public space, introduced by understanding of a space on the basis of new paradigm, expands the territory of life and overcomes tile negative environmental problem like disorder, increase of entropy.

  • 1년에도 수십 수백 개씩 스타트업이 생겨나고 있다. 아마도 모두 미래의 구글과 페이스북, 그리고 아마존이 되길 희망하며 하루하루 가열차게 달리고 있다. 하지만 그 많은 스타트업 중 소위 성공했다 불릴 수 있는 기업은 손에 꼽는다. 능력 있는 창업가, 기발한 사업 모델과 아이디어 그리고 이를 뒷받침해 줄 기술력과 자본이 있다고 성공할 수 없다. 스타트업 기업을 굴러가게 하는 힘은 결국 그 조직의 구성원에게서 나오기에 성공한 스타트업에겐 모두 그들 만의 '조직문화'가 있다. 그게 모두에게 좋은 문화일 필요는 없을 것이다. 그 조직에 가장 접합한, 그래서 구성원의 구성원의 공감대를 사 '일하고 싶은 회사'가 될 수 있게 하는 '조직 문화'가 있는 스타트업이 수많은 인재를 모아 성장을 거듭해 올 수 있었고 그것이 결국 스타트업을 성공으로 이끌었던 것이다. 이런 조직 문화는 회사 초창기에 세팅할수록 해당 기업의 성공 확률도 높아진다. 7년 미만의 초기 스타트업 기업을 대상으로 조직문화 유형이 스타트업 구성원의 조직 몰입과 조직성과에 어떠한 영향을 주는지에 대한 실증분석을 목적으로 하였다. 초기 스타트업 기업의 조직문화 차원은 경쟁가치모형의 혁신문화와 위계문화로 구분하였으며, 조직성과는 스타트업의 서비스, 제품을 경험한 이용자들의 서비스 만족도를 활용하였다. 조직문화는 외부환경에 대한 적응과 조직내부 통합의 문제를 해결하기 위하여 구성원들에 의해 창조 발전되어 학습되는 기본가정으로서 스타트업 구성원들에 의해 공유된 가치(values), 신념(beliefs), 규범(norms)의 체계로 정의한다. 따라서 어떠한 조직문화를 갖는냐에 따라 조직 구성원의 몰입, 충성심, 직무동기, 직무성과는 물론 조직성과와 혁신을 포함하는 여러 조직 요인도 직 갑적인 영향을 받는다. 7년 미만의 초기 스타트업 혁신문화가 스타트업 구성원의 조직몰입에 긍정적인 영향을 미치며, 조직몰입이 스타트업 서비스, 제품을 경험한 이용자들의 서비스 만족도에도 긍정적인 효과가 있는 것으로 나타났다.

  • This study investigates the occupational mobility patterns of young wage employees at the local level of the labor market and empirically examines the interplay between worker-level and local labor market-level determinants between 2010 and 2020. The 4th to 14th waves of the Youth Panel 2007 were integrated with the Korea Network for Occupations and Workers and the Local Area Labor Force Survey for estimation using hierarchical linear model. Our results indicate that Gross Regional Domestic Product per capita is key determinant of occupational upward mobility. Also, Estimates of employment size, population density, and the unemployment rate of local labor market have different effects depending on the education level and occupational location of youth workers, suggesting that the effects of structural factors of local labor market may not be distributed equally among all youth wage workers. The findings have policy implications regarding the recent rise in inequality and polarization in local labor markets.

  • The purpose of this study was to extract hierarchical learning elements in the area of 'Algorithms and Programming' in the 2022 revised secondary informatics curriculum. Intrinsic validity was secured by considering the core ideas presented in the curriculum and the content elements of 'knowledge/understanding', 'process/skills', and 'values/attitudes', and extrinsic validity of the learning elements was obtained through FGI and CVR with 25 experts. The learning elements derived from this study are 7 in the first stage, 18 in the second stage, and 26 in the third stage for middle schools, and 8 in the first stage, 23 in the second stage, and 27 in the third stage for high schools. Although the scope and size of knowledge in each stage may differ, the hierarchy of knowledge in the first stage, which is materialized in the second and third stages, provides direction on how knowledge should be taught. This study is expected to contribute to the implementation of the new curriculum in schools and to improve teachers' understanding of the curriculum.

  • This study analysed the narrative of and , two history documentary broadcasted on KBS, in terms of story-telling and discourse. And it also examined whether TV as mass media could provide an alternative interpretation against the dominant historical awareness. As a result, both programmes showed limitations on representing subversive point of view to the dominant ideology. At the story-telling level, firstly, they represented in a way of male-hero narrative though they were describing the history of woman, and while representing woman as a public figure they eliminated her feminity and individuality. Secondly, before evaluating woman as a historic figure they previously appreciated her appearance in a male-point of view. Thirdly, although they were telling the story of woman in a political view, they focused on love triangle, therefore failed to make her as a public figure. The discourses of both programmes were anchoring the existing historical interpretation instead of offering an alternative historical imagination. The narrator who were telling history at the studio in a omniscient viewpoint took a role as a meaning definer, placed at the highest rank in the hierarchy of discourse structure. Especially in , the dramatized images to cover lack of visual data helped anchor the patriarchal narrative and reduced the possibility of subversive interpretation on historic figure.
