  • Because of comfortable texture and easy treatment, more and more knit products has been required for leisure such as sports, traveling, hobbies, and various social activities. Therefore, the demand of knit is gradually increasing in the clothing industry. There are, however, several issues, which require solutions, and we must develop higher value-added products, which differentiate from those of developing countries allowing us to compete and win in the world market. The patterns on porcelain of underglaze iron, which had been popular from late-l5th century to mid-16th century, are diverse, unique, and traditional--so valuable patterns of our own. The computer hitting machine enables the designer to conceive new designs and produce samples of fabrics within a few minutes, which allows us to save time for mass production. Therefore, it is an essential tool for the knitting industry. After collecting, analyzing, and choosing various patterns on porcelains of underglaze iron, This study reflects the actual experience of hitting the fabrics with the patterns through the computer knitting machine which is also used to produce patterns after designing the new patterns through Adobe Illustrator and Photoshop, which has several merits. This article compares and analyzes them for production, which uses the patterns that has been designed from the patterns on porcelains of underglaze iron.

  • Bromotopsentin (BSM) is a bisindole alkaloid compound, which is recognized as a metabolite of the marine sponge Spongosorites sp. In this study, the antioxidant activity of BSM was investigated. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, the trolox equivalent antioxidant capacity (TEAC) assay, the superoxide radical scavenging (NBT) assay, the lipid peroxidation and hydroxyl radical-induced DNA damage assays were carried out to evaluate the antioxidant activity of BSM. It was found that BSM had stronger scavenging activity on the stable free radical DPPH and superoxide radical than L-ascorbic acid with an $IC_{50}$ value of 62 and 64 ${\mu}M$, respectively. The TEAC value which indicated the total antioxidant capacity of BSM was about 0.8, which was also stronger than L-ascorbic acid. About 1.3 ${\mu}M$ of BSM induced 50% inhibition of lipid peroxidation. 60 nM of BSM exhibited a significant protective activity against DNA strand scission by hydroxyl radical on pBR322 DNA. Taken together, we suggest that BSM possesses strong antioxidant activity, and could be a valuable new addition to the list of anti-aging chemotherapeutic agents.

  • The purpose of the study were to analyze MathThematics textbooks and Korean middle school mathematics and to investigate the difference among the textbooks in the view of mathematical communication. According to the results, the textbook developers made a variety of efforts to develope students' mathematical communication ability. Students were encouraged to communicate with others about their mathematical ideas or problem solving processes in words or writing by means of discussion, oral report, presentation, journal, etc. MathThematics textbooks provided student self-assessment opportunity to improve student performance in problem solving, reasoning, and communication. In communication assessment, students can assess their use of mathematical vocabulary, notation, and symbols, the use of graphs, tables, models, diagrams and equation to solve problem and their presentation skills. The assessment activities would make a positive impact on the development of students' mathematical communication ability. MathThematics textbooks provided a variety of problem situation including history, science, sports, culture, art, and real world as a topic for communication, however, the researcher found that some of Korean textbooks depends heavily on mathematical problem situations.

  • Objective: This study examined the effects of dynamic tape applied to the patellofemoral joint on the knee valgus angle, muscle activity, and ground reaction force during a single leg squat (SLS) and single leg landing (SLL). Design: Cross-sectional study. Methods: Twenty-four subjects (11 male, 13 female) who met the inclusion criteria were screened by the knee palpation and patella compression tests. First, the knee valgus angle and muscle activity during SLS were measured. Second, the knee valgus angle and ground reaction force during SLL were measured. For the intervention, a patella joint loop using dynamic tape was used. The knee valgus angle, muscle activities in SLS and SLL after the intervention, and the ground reaction force were measured in the same way. A paired t-test was used to examine the difference between before and after the intervention. Results: The knee valgus angle showed a statistically significant improvement after dynamic taping application in SLS and SLL (p<0.05). The differences in muscle activity of the VL/VMO and ground reaction forces were not statistically significant after dynamic taping application in SLS and SLL. Conclusions: This study showed that dynamic taping applied around the patellofemoral joint was effective in improving the knee valgus angle in SLS and SLL and had a reduced risk of secondary injury during sports activity.

  • Background: Advances in surgical techniques, implant technology, radiotherapy, and chemotherapy have increased the recovery chances of patients with bone sarcomas. Accordingly, patients' expectations on life quality have also increased, highlighting the importance of objective evaluation of the functional results of reconstruction. Methods: Thirteen patients with distal femoral endoprosthesis, who had been followed for an average of 2.9 years were evaluated. Postural stability, daily energy expenditure, muscle power, and range of motion were the four parameters analyzed in this study. The Musculoskeletal Tumor Society (MSTS) score and Toronto Extremity Salvage Score (TESS) were used to assess postoperative function and examine correlations with other parameters. Results: Patients had sedentary activities in 84% of their daily lives. They exhibited a slower speed in the walk across test and a higher sway velocity in the sit-to-stand test (p = 0.005). MSTS scores were significantly correlated with the daily energy expenditure and walking speed. Conclusions: Objective functional results acquired from various clinics will provide significant data to compare reconstruction techniques, rehabilitation protocols, and surgical techniques. In this way, it will be possible to satisfy the expectations of patients that increase in relation to enhanced recovery.

  • As the spread of the health and wellness trend continues worldwide, many consumers are spending much time on sports activities and expressing their individuality through sportswear. This study analyzes the trade networks of major exporters and importers of athleisure wear to provide an exporting policy for Korean apparel companies. As a result, The USA was found to import the most athleisure wear. On the other hand, China had the largest number of athleisure wear exports, and India's exports, which are becoming increasingly important as apparel producers were notable. Next, using the concept of the centrality of social network analysis, it was found that the USA was the largest importer and the center of athleisure wear's export network, but its influence has decreased gradually since 2010. China has the highest out-degree and betweenness centrality and center in the export of athleisure wear. The centrality of Asian countries such as India and Vietnam has increased. In Korea, the import of athleisure wear has increased greatly, but the export of athleisure wear has continuously decreased. Korea has less price competitiveness than other developing countries in Asia, but many Korean athleisure wear clothing brands are now attracting popularity not only in Korea but also in other countries with their excellent technology and design. In the future, the exporting policy of Korea's athleisure wear should focus on high value-added and differentiated products.

  • Pediatric ankle fractures can cause physeal injuries which can lead to the shortening of the fibula. This induces a lateral shift of the talus, valgus tilt, and instability of the ankle joint, which can result in an arthritic change in this joint. Patients with a shortening of the fibula may complain of constant pain and restricted movements in their daily lives and during sports activities. Ankle reconstruction with fibula lengthening Z-osteotomy can provide excellent results if arthritis is absent or minimal, especially in young and active patients. To the best of the authors' knowledge, this is the first report in South Korea regarding the treatment of fibula shortening following a growth arrest due to injury.
