Local culture plays a role in enhancing the cultural competence of citizens by approaching branding from the perspective of brandization by implying value amid changes in local traditions and modern times. Therefore, this study established a research model with brand loyalty, brand recognition, perceived quality, and brand image as dependent variables in order to analyze the impact of local cultural characteristics on cultural brand asset components. We tested the research hypothesis and analyzed it, As local cultural characteristics affect cultural brand asset components, it was found that it is necessary to change the perception of local culture and promote traditional culture. In addition, Yeoju City needs to plan a festival that combines tradition and local culture through the convergence of content and cultural policy for the recognition and brand image of the Yeoju Yeongneung, a World Heritage Site, and it is urgent to change the direction of citizens. In addition, it was found that it is desirable to expand research on the formation of cultural brand assets according to local cultural affinity.

This study conducts to examine the effect of purchase intention on social shopping by connection density and centrality which is a structural characteristic of social network. Furthermore, this study suggests and analyses the difference of social shopping purchase intention between online community which focuses on a group and SNS(social network service) which focuses on an individual. To examine these reason, this study proposes hypotheses that reflects structural characteristic then analyses them. The result of analysis shows that the purchase intention on social shopping seems to be high when the density of connection is high and the purchase intention seems to be high when the centrality is high as well. Moreover, there is difference in the purchase intention on social shopping between online community and SNS and it is found that both cases where the connection density is high in the online community and the connection centrality is high in SNS have significant impact on the purchase intention. Based on these results, this study provides an implication on the importance on network structure in social network and social shopping and to increase the purchase intention of social shopping, this study suggests the implication on the importance and direction which understands the structure of social network type.

We experimentally investigated the effect of applied DC electric fields on the flame spread over polyethylene-coated electrical wire. The flame-spread rates over electrical wire with negative and positive DC electric fields from 0 to ${\pm}7$ kV were measured and analyzed. We compared the results for DC electric fields with previous results for AC electric fields. We explored whether or not various flame shapes could be obtained with DC electric fields and the main reason for the flame-spread acceleration, particularly at the end of the electrical wire, for AC electric fields. We found that DC electric fields do not significantly affect the flame-spread rates. However, the flame shape is mildly altered by the ionic wind effect even for DC electric fields. The flame-spread rate is relevant to the flame shape and the slanted direction in spite of the mild impact. A possible explanation for the flame spread is given by a thermal-balance mechanism and fuel-vapor jet.

Weaving is defined as the crossing of two or more traffic streams traveling in the same general direction along a significant length of highway without the aid of traffic control devices. Compared with other freeway sections, perturbation is easy to happen at weaving section. Because there are a lot of lane-changing maneuvers at the weaving section, traffic is subject to turbulence in excess of that normally presents on freeway basic section. This turbulence causes operational problems and its impact must be considered. The purpose of this paper is to perform a basic study on flow characteristics by lane, which can be achieved through analyzing breakdown phenomenon in the microscopic approach. The study made use of data derived from the aerial photography for the microscopic analysis. This research produced the 30-second interval data such as flows, speeds, and densities for the macroscopic analysis and derived the vehicular data to draw time-space diagram for the microscopic analysis. The paper analyzed the traffic characteristics using flows, speeds and densities variation and investigated the conditions of breakdown occurrence with the time-space diagrams. The breakdown phenomenon was identified at weaving section and the propagation from free flow to synchronized flow was observed in this study. In the future, the findings help develop the traffic operational algorithm to manage the traffic congestion under ubiquitous circumstance since the conditions of breakdown Phenomenon can be understood more.

Children's literature has a significant impact on children's intelligence and emotional development. The interest in children's literature is increasingly growing with the expectation of the award winning books and the educational values of children's books. Although the interest has brought about a quantitative increase in the domestic children's books, it has difficulty selecting high-quality children's books among various books. In such an environment, the Children's Literature Award will provide an authoritative source of choice, which will help guide the selection of quality books to those who want to read children's books. In addition to this trend, the library should check the status of winning works and incorporate them into new collection development policies. The purpose of this study is to present the direction of the library book development policy of the public library. For this purpose, 10 public libraries in Seoul, Korea were selected and analyzed quantitatively and qualitatively through the collection status of the children's literature winning books, loan status, turnover, Bonn's use Factor, and Trueswell's 80/20 rule. Based on the results of this analysis, we would like to suggest some issues to be reflected in library development policy of the future.

With the spread of digital trade, the share of digital trade under the global trade environment is increasing. However, since there is no international digital trade standard, the discussion to establish a new trade rule has important significance. Countries around the world are implementing digital trade policies in consideration of their own interests, but different regulatory policies are causing trade conflicts. In order to provide safeguards against personal information infringement due to the free movement of data across borders, major countries around the world have taken measures to localize data, and the EU has enacted GDPR. And the United States regards the imposition of the digital tax as a trade barrier, and some countries oppose the implementation of the digital tax for fear of negative impact on their countries. However, discussions on the global digital tax, centered on the OECD and the G20 are making progress. As it is highly likely that a digital tax agreement will be drawn up within this year, countermeasures must also be prepared. Therefore, this study presents implications for the future direction of Korea's trade policy by examining recent trends in digital trade norms and analyzing major issues in digital trade.

In this study, the efficacy of Engineered Cementitious Composite(ECC) jacket for masonry fences subjected to lateral dynamic load was experimentally verified through a shaking table test, comparing it with the performance of an unreinforced masonry(URM) fence. Firstly, dominant frequencies, modal damping ratios and deformed shapes were identified through an impact hammer test. URM and ECC-strengthened fences with heights of 940mm and 970mm had natural frequencies of 6.4 and 35.3Hz, and first modal damping ratios of 7.0 and 5.3%, respectively. Secondly, a shaking table test was conducted in the out-of-plane direction, applying a historical earthquake, El Centro(1940) scaled from 25 to 300%. For the URM fence, flexural cracking occurred at the interface of brick and mortar joint(i.e., bed joint) at the ground motion scaled to 50%, and out-of-plane overturning failure followed during the subsequent test conducted at the ground motion scaled to 30%. On the other hand, the ECC-jacketed fence showed a robust performance without any crack or damage until the ground motion scaled to 300%. Finally, the base shear forces exerted upon the URM and ECC-jacketed fences by the ground motions scaled to 25~300% were evaluated and compared with the ones calculated according to the design code. In contrast to the collapse risk of the URM fence at the ground motion of 1,000-year return period, the ECC-jacketed fence was estimated to remain safe up to the 4,800-year return period ground motion.

As interest in ESG has been increased, it is easy to find papers that empirically study that a company's ESG activities have a positive impact on the company's performance. However, research on what ESG activities companies should actually engage in is relatively lacking. Accordingly, this study systematically classifies ESG activities of companies and seeks to provide insight to companies seeking to plan new ESG activities. This study analyzes how Chinese manufacturing companies perform ESG activities based on their dynamic capabilities in the global economy and how they differ in their activities. This study used the ESG annual reports of 151 Chinese manufacturing listed companies on the Shanghai & Shenzhen Stock Exchange and ESG indicators of China Securities Index Company (CSI) as data. This study focused on the following three research questions. The first is to determine whether there are any differences in ESG activities between companies with high ESG scores (TOP-25) and companies with low ESG scores (BOT-25), and the second is to determine whether there are any changes in ESG activities over a 10-year period (2010-2019), focusing only on companies with high ESG scores. The results showed that there was a significant difference in ESG activities between high and low ESG scorers, while tracking the year-to-year change in activities of the top-25 companies did not show any difference in ESG activities. In the third study, social network analysis was conducted on the keywords of E/S/G. Through the co-concurrence matrix technique, we visualized the ESG activities of companies in a four-quadrant graph and set the direction for ESG activities based on this.
