This study investigates whether the image of the casual Hanbok brand is being communicated to consumers successfully. We conducted a semantic network analysis to identify ways of revitalizing communication between casual Hanbok brands and consumers; in addition, we quantitatively evaluated the effectiveness of communication marketing through Quadratic Assignment Procedure (QAP) analysis. Unstructured data from 2014-2021 were collected through portal sites and then refined and networked. Our analysis showed that casual Hanbok brands generally target younger people and that different brands employ similar methods to promote and popularize the casual Hanbok style. Consumers tended to recognize and show interest in casual Hanbok, suggesting the potential to expand the market to Blue Ocean. However, some of our findings revealed the potential factors of style coordination risk and prejudice against existing Hanbok, which could potentially hinder casual Hanbok's uptake and adoption. We conclude that increasing the demand for casual Hanbok depends not only on delivering an accurate brand image to consumers but also on balancing fashion with traditional images when planning products and providing styling information.

Public transportation systems play key roles in supporting dynamic activities and interaction between urban places. Especially, high efficient public transportation systems are required in order to support large traffic demands in urban areas. In this paper, we define a new metric, structural activation level (SAL), to replace the conventional transportation share ratio (TSR) measuring efficiency of public transportation systems. First of all, we access the Korea Transport Database (KTDB) and download origin-destination data by transport types to construct traffic networks with respect to transport types for each city. Then, we calculate the QAP (Quadratic Assignment Procedure) correlation between each traffic network and the total traffic network for each city to investigate SAL by comparing cities one another. The results of our investigation reveal inconsistency between TSR and SAL. In Daegu, TSR of public transportation systems is relatively low while SAL is high. In Deajeon, however, SAL is low while TSR is high. Therefore, we suggest to take into consideration SAL as well as TSR in order to investigate the degree of activation of public transportation.

본 논문에서는 네트워크 분석방법을 활용하여 대학 중심의 산학협력 네트워크의 구조적 특성을 분석하였다. 최근 기술협력 및 공동연구가 성과창출에 긍정적 영향을 미치는 것이 증명됨에 따라, 혁신성과 창출을 위하여 주요 참여주체(대학 및 공공 등)를 중심으로 다양한 형태의 협력활동 추진과 정부의 정책적 지원이 활발하게 진행되고 있다. 하지만 이러한 노력에도 불구하고 성장동력 창출은 다소 미흡한 상황이기에 대학중심의 산학협력 활동강화를 위한 혁신 네트워크 구축 방안 마련이 필요한 시점이다. 이에 본 연구에서는 산학협력 유형(특허, 논문, 공동연구, 기술이전)에 따른 네트워크를 구축하고, QAP상관분석 및 QAP회귀분석을 실시하여 서로 다른 유형의 산학협력 네트워크간 관련성 및 연관성을 통계적 관점에서 분석하였다. 분석결과 공동연구 네트워크는 논문 네트워크와 밀접한 관련이 있으며, 다른 산학협력 네트워크와도 관련성을 가지고 있는 것으로 나타났다. 본 연구는 대학의 새로운 성장동력 창출에 필요한 산학협력 전략수립 및 협력 파트너 발굴 등과 같은 혁신활동을 지원할 수 있을 것이라 기대한다.

The purpose of this study is to grasp the understanding of smart cities and to review whether the common perception of smart cities, as people understand it, is changing over time. This study analyzes keywords related to smart cities used in social network services (SNSs) in 2011, 2016, and 2020 respectively through semantic network analysis. Smart city discussions appearing on SNS in 2011 mainly focused on technology, and the results of 2016 were generally similar to those of 2011. We can also find policy or business-oriented characteristics in emerging countries in 2020. We highlight that all the results of 2011, 2016, and 2020 have some correlation with each other through QAP(Quadratic Assignment Procedure) correlation analysis, and among them, the correlation between 2011 and 2016 is analyzed the most. The results of the frequency analysis, centrality analysis, and CONCOR(CONvergence of interaction CORrelation) analysis support these results. The results of this study help establish policies that reflect the needs and opinions of citizens in planning smart cities by identifying trends and paradigm transitions expressed by people in SNS. Furthermore, it is expected to help emerging countries by enhancing the understanding of the essence and trend of smart cities and to contribute by suggesting the direction of more sustainable technology development in future smart city policies for leading countries.
