The purpose of this paper is to verify the mediating effect of peer relations and self-esteem in the relationship between the effects of deficiency of children using local children's centers on school life adaptation. The survey subjects were selected from 424 students in the first year of middle school who were used the local children's center, and analyzed using data from the 4th of the local children's center. Summarizing the analysis results, peer relationships were found to have a complete mediating effect in the relationship between deficiency and school life adaptation. Second, it was verified that self-esteem has a partial mediating effect in the relationship between deficiency and school life adaptation. Children using local children's centers experience deficiencies in various areas of society, but as can be seen from the results of this study, it was suggested that they can help adapt to school life by promoting self-esteem and peer relationships. Therefore, we would like to propose the development of programs and practical implications for promoting children's adaptation to school life, and the expansion of the field of children's research using local children's centers.

Purpose: The purpose of this study was to retrospectively evaluate the effect of 'Blocking Kirschner Wire (K-Wire) Technique', which has been developed to reduce protrusion of the lateral wall, in maintaining the level of reduction through clinical and radiological outcomes. Materials and Methods: Twenty-two patients with displaced intra-articular calcaneal fractures who used the blocking K-wire to maintain reduction (group A) and 44 patients that did not use blocking K-wire and were paired in 1:2 ratio with those Group A patients (group B), between January 2015 and December 2017 were enrolled in the study. All surgical procedures were performed via the extended sinus tarsi approach, and internal fixation using cannulated screws, Steinmann pins and K-wires was performed. American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale and postoperative recovery of exercise ability were compared for postoperative clinical outcomes. The radiological results were compared the Böhler angle, Gissane angle, calcaneal height and width, step off of posterior calcaneal joint, and the degree of protrusion of the lateral wall. Moreover, postoperative complications in both groups were compared. Results: There were no significant differences in the clinical outcomes of the two groups (p=0.924, p=0.961). The amount of Böhler angle, Gissane angle, calcaneal height and width, and step off of posterior calcaneal joint from the radiological results was not significantly different between the two groups (p=0.170, p=0.441, p=0.230, p=0.266, and p=0.400). However, the degree of protrusion of the lateral wall was 1.78 mm and 4.95 mm in group A and group B, respectively, and the difference between the two groups was significant (p=0.017). Although sural nerve entrapment and painful exostosis were more frequent in group B, they were occurred in a non-significant manner (p=0.293, p=0.655). Conclusion: Most of the clinical and radiological results as well as the complications were not significantly different between the two groups. However, the degree of protrusion of the calcaneus lateral wall in group A was promising. The 'Blocking K-Wires Technique' established by the authors may be an effective surgical option for maintaining the reduction of the lateral wall protrusion in displaced intraarticular calcaneal fractures.

This study emphasizes that the survival strategy of universities should be a co-evolution strategy based on ecological thinking. Therefore, the purpose of the research is to present a theoretical framework for dividing the university innovation ecosystem into four stages and building a co-evolution strategy for each step, as universities play a prominent role in regional innovation ecosystems. Thus, our research method focused on literature research, and the theoretical framework for the university innovation ecosystem used Moore's Enterprise Ecosystem Model (1996). The university's ecological innovation strategy is divided into four stages of development, and a step-by-step co-evolution strategy is presented. Findings are summarized as follows. The pioneering stage involves the creation of values of the university-led innovation ecosystem. The expansion stage focuses on the establishment of critical mass. The authority stage covers maintaining authority and bargaining power. The renewal stage features continuous performance improvement. In particular, this theoretical model of the university-regional innovation ecosystem is meaningful in that it provides a theoretical basis for enhancing the effectiveness of government financial support projects, and for individual universities, it provides a framework for strategies suitable for their ecosystem building process.

The purpose of this study is to explore ways in which the flower design industry can utilize podcasts that are rapidly growing in recent years. I selected foreign flower podcasts that are ranked on the global podcast chart, and examined the genre, content, components, show hosts and etc. By analyzing the characteristics of the podcast, the type of communication between the host and the audience, the audience interaction, the industry connection, and the media expansion strategy, I tried to derive the possibility of the flower podcast in Korea. As a result of analyzing foreign flower podcasts, podcasters built listener communities based on their rich experience and knowledge through podcasts and used them for education and marketing. They acted as leaders in the industry or led public opinion such as the sustainable flower industry. Podcast shows were repurposed as various content and used to spread flower design culture. In Korea, flower podcasts can be the basis for the formation of a community related to the flower design industry. Flower design experts can use podcasts as a source asset for various content. Listeners within the industry can get hands-on knowledge about the business from flower podcasts. The popular flower podcast will contribute to the vitalization of flower design culture and industry. Flower podcasts can be a starting point to actively cope with the era of personal media.

The purpose of this study is to analyze the characteristics and problems of the content of flower design education videos on YouTube and to search for improvement direction. The subjects of analysis were 129 pieces of videos uploaded in the last one year including 'craftman floral design' as a search term. The result shows that contents covered were practical lectures, theory lectures, test related tips, job and character introduction, test work, educational guidance and publicity. The production format could be divided into studio lecture, classroom lecture, video feature, interview, Vlog, and television program. The hub-type programming strategy that periodically uploads the videos satisfying the target audiences' interests is mostly applied. The type of lecture covered 'practical skill test' got a good response from the users. Overall, content diversity, interaction between creators and users, and harmonious programming strategies are lacking. In order to improve this, it is necessary for emotional and expressive creators to pioneer differentiated fields and practice based on actual field. The introduction of interactive elements such as games and quizzes and the application of new media technologies such as VR and AR are worth trying. Three strategic types of 'hero', 'hub', and 'how to' should be applied complementary. As the demand for education content related to flower design is expected to expand in the future, it is required to develop content that can be used in various platforms, foster professional creators, and develop associated business models.

In recent years, the concept of influencer marketing has experienced rapid growth in both academia and industry, leading to its emergence as a crucial consideration in the marketing strategies of many businesses. Despite the significance and expansion of the influencer market, however, research on the topic has not kept pace with its growth. Thus, this study seeks to address this gap by empirically analyzing the impact of influencer characteristics on consumer behavior through the coexistence of buyers and providing an empirical contribution to expand the relevant literature. To accomplish this, a survey was conducted with a sample of 400 individuals who had purchased a product through an influencer, and 384 responses were ultimately utilized in the analysis. The results revealed that the attractiveness and empathy of influencers had a positive impact on satisfaction among coexisting buyers, while also having a negative impact on dissatisfaction. In contrast, expertise had no impact on satisfaction, but a positive impact on dissatisfaction. Moreover, satisfaction was found to have a positive impact on brand image and recommendation intention, whereas dissatisfaction had a negative impact on both. Overall, this study adds to the growing body of literature on influencer marketing by providing empirical evidence of the impact of influencer characteristics on consumer behavior, specifically through the lens of coexistence with buyers. These findings hold important implications for businesses looking to develop effective influencer marketing strategies that can enhance their brand image and recommendation intention among consumers.

Purpose: The purpose of this study is to evaluate the effects of intratunnel fixation in the tibial side on the arthroscopic ACL reconstruction with quadruple hamstring tendon at the second look arthroscopy. Materials and Method: From Dec 1999 to May 2005, we arthroscopically reexamined 32 cases who had been done arthroscopic ACL reconstruction with quadruple hamstring tendons. Hamstring tendons of all cases were fixed at femoral side with RigidfixTM. At the tibial side hamstring tendons were fixed only Post-tie (Group I) or Post-tie combined with IntrafixTM (Group II). At the time of second look arthroscopy mean age of cases was 30 years and mean duration for second look arthroscopy was 21.3 months. We analyzed the results with IKDC score, KT-1000 arthrometer under anesthesia, Telos stress radiography, tibial tunnel widening on the radiography and second look arthroscopic findings. Results: Group II had more superior than group I at side to side differences with KT-1000 and Telos stress radiograph, IKDC score, but the differences were insignificant. At arthroscopic evaluation, Group ll also had more superior than group I at graft tension and graft appearance, graft synovialization, but the differences were insignificant. Tibial tunnel widening in the knee AP radiograph was 2.3 mm in Group I and 1.7 mm in Group II and the difference was significant. (P=0.042) Conclusions: Additional procedure of tibial intratunnel fixation in arthroscopic ACL reconstruction with autogenous hamstring tendon significantly prohibited from tibial tunnel widening but clinical results, radiologic joint stability, findings in second look arthroscopy were insignificantly different. We concluded that Post-tie itself induced satisfactory clinical results, joint stability and graft maturation and that tibial tunnel widening did not affect the results.

This article is to report a new technique for reconstruction of the anteromedial and posterolateral bundles of anterior cruciate ligament by separate tensioning and fixation of the each bundle. Method : Tibial and femoral tunnels were made with conventional technique of anterior cruciate ligament reconstruction. Tibial tunnel was enlarged $5\~7$ mm in anterior-posterior direction to make oval it in cross section. When preparing the Achilles tendon allograft, bone plug portion was trimmed as the conventional technique. The tendinous portion was trimmed as two separate bundles by dividing the tendinous portion longitudinally, so the graft is shaped like 'Y'. The bone plug portion of allograft was inserted into the femoral tunnel and fixed with absorbable cross pins. Two ligamentous portionss of the distal part of the grafts were tensioned separately at the external orifice. Anteromedial bundle was fastened under maximum tension with the knee flexed 90 degrees by post-tie method. The posterolateral bundle was fixed by the same technique with the knee in full extension. Then, an absorbable interference screw was inserted between the two bundles upto the upper end of the tibial tunnel, to get more initial rigidity of the reconstructed graft as well as to locate the two bundles in more anatomic position.
