The study compares busy streets with the ones that are not and finds out what makes people think the street is busy. Based on this comparison and analysis, the study reflects on measures to make streets busy. First of all, busy streets are classified into three parts: shopping zone, business zone, and the combination of the two. The study analyzes whether the street is busy due to the certain system or structure of the street or it is busy due to certain design of the street, and the analysis is done in those three categories mentioned above. The research was carried out in busy streets with similar characteristics in both Korea and Japan. Physical factors that turn ordinary streets into busy ones are focused and analyzed. The visual perception is analyzed. As a result, similarity and difference between designs of physical factors of streets in both countries are discovered. Ideal arrangement and design of physical factors that contribute to the making of busy streets are also found. Based on these data, design that makes busy streets with different characteristics is presented here.

Entrepreneurial resilience is one of the core competencies that young entrepreneurs should own. However, compared to its importance, related studies about this topic are rare, especially in Korea. Therefore, this study, for empirical analysis, included resilience to the research model expanding existing research. The purpose of this study is to identify the direct effects of perceived norms of young entrepreneurs, entrepreneurial self-efficacy, and entrepreneurial resilience on entrepreneurial intentions, and to identify the mediated effects between perceived norm, entrepreneurial self-efficacy, and entrepreneurial intention. The data used in this research were collected through questionnaires from 443 potential young entrepreneurs. Our experimental result show that social norm and entrepreneurial self-efficacy were positively related to entrepreneurial resilience. Moreover, personal norm, entrepreneurial self-efficacy, and entrepreneurial resilience were statistically significant on intention of entrepreneurial. As a result of the indirect effect, entrepreneurial resilience mediates the relationship between social norms, entrepreneurial self-efficacy, and entrepreneurial intention. Finally, this research has significant meaning because it shows the importance of entrepreneurial resilience to entrepreneurial intention of young entrepreneurs. However, the limitation of this study relates to the restriction of sample in certain regions and universities.

The study analyzed the greenness index that residents experience on the streets of rural areas, where characteristics are different from those of urban areas and the effects of these characteristics were investigated. In Yesan-gun, Chungnam, in order to analyze the greenness indices, the streets were categorized into 7 types. Then, two types of streetscape greenness indices were surveyed, analyzed, and compared. One is the street-trees greenness index which takes into account only the trees lining the street and the other is the street greenness index considering total artificial green, natural green, and productive green surfaces. As a result, using the street-tree greenness index the street greenness index of Yesan-gun was analyzed as 15.93% on national highways, 26.14% for local roads, 28.28% for gun-roads, 24.72% for myun-roads, 40.70% for li-roads, 32.78% for nong-roads, and 18.36% for urban planning roads. Using the street greenness index, the street-trees greenness index was analyzed to be 5.02% for national highways, 9.10% for local roads, 8.55% for gun-roads, 4.51% for myun-roads, 6.92% for li-roads, 2.56% for nong-roads, and 9.39% for urban planning roads. To analyze what factors have an impact on the street-trees greenness index and the street greenness index, the study analyzed the effects of street side-land uses, lane types, street-trees, and sidewalks. As a result, both the street greenness index and the street-trees greenness index responded according to the land use adjacent to the street, lane types, and sidewalks. The street greenness index did not change due to the existence of street-trees, but the street-trees greenness index did. Through comparison with other studies, it was found that Yesan-gun needs to improve its streetscape to improve its greenness index rating.

The purpose of this study is to examine the experiences and attitudes of elementary pre-service teachers, the level of entrepreneurship core competencies, and to analyze differences in entrepreneurship core competencies by grade, gender, and attitude. To this end, 208 elementary pre-service teachers who responded to the online questionnaire surveyed their experience, attitudes, perceptions, entrepreneurship attempts, and entrepreneurship core competency levels. As a result, pre-service teachers had a low level of understanding and direct participation in entrepreneurship education, the need for entrepreneurship education for elementary school students and teachers was high. The average of the value-creation competency group consisting of innovation, social value orientation, and change agility was relatively lower than the challenge, group creativity, and self-directed competency group. The difference of the entrepreneurship core competency level between the grades was not significant, and female students' competency levels were statistically significantly higher than male students. In addition, the average of the four core competencies of entrepreneurship in the group that recognizes the importance of entrepreneurship as essential competencies was statistically higher than that of their counterparts. Based on the results of this study, the implications for the design and development of a program for enhancing entrepreneurship competency for elementary school pre-service teachers were presented.

This study aimed to measure street centralities with the street width, and to analyze their effects on the residential and non-residential land prices in Seoul, South Korea. Most of the studies on urban economics and policy focusing on the urban spatial structure have evolved in terms of their perspective from monocentric to polycentric models. Recently, their themes shifted to measuring street centralities and capturing their effects on urban phenomena. To expand the existing studies and discussion, this study analyzed the street centralities with the street width, and how they changed the land prices. Multilevel regression models generated a few key findings relevant to the relationship between street centralities and land prices. While a higher detour volume and closeness to wider streets commanded premium residential land prices, higher visibility and detour volume to wider streets were associated with higher non-residential land prices. These findings suggest a robust connection between street configuration and near-land prices. Thus, the results of this study suggest a few insightful policy implications for urban planners, urban designers, real estate developers, and appraisers.

This study established a plan to establish the roadside green for enhancing the urban green network and enhancing of urban greenery in Songpa-gu. As for the present conditions of the streets, that of the parks, the green axes, sidewalk in Songpa-gu were analyzed. This study derived 19 parks by the roadside and 13 lines to connect green axes. The result of roadside greenery status were selected 56,546m lines by natural green space and constructed green space. The result of sidewalks width were selected 8,600m lines that sidewalks width more than 5m for enhancing urban green network in Songpa-gu. For enhancing the urban green network lines were selected: Olympic Expressway, Songpa-daero, Nambusunhwan-no and Wiryeseong-gil. To improve the street planting strips, two plans were suggested: to improve the green structures of the street planting strips mainly with shrubs and to effectively create street planting strips through the green spaces along the streets. A plan to promote the amount of planting street trees in Songpa-gu analyzed the streets. Complements the understory layer sections were the highest the entire length of 34,206 m of 63.6% in strengthening for network streets. Greenspace network streets were calculated for planting of volume by promotion plan. Planting volume increased 4,708 trees before expand planting plan, so the total tree was considered 9,518 trees.
