본 연구에서는 polystyrene(PS) 술폰화 반응을 통하여 얻어진 sulfonated polystyrene(SPS)과 trimethylolpropane ethoxylate triacrylate(TMPETA) 가교제를 다양한 조성으로 혼합하여 캐스팅한 후, 전자선을 조사하여 가교 SPS/TMPETA 막을 제조하였다. FTIR 분석과 술폰화도 측정을 통하여 술폰산기가 PS 고분자에 도입되어 SPS 고분자가 성공적으로 제조되었음을 확인하였다. 제조된 SPS/TMPETA 막의 젤화율 측정을 통해 조사선량 및 가교제 함량이 증가할수록 가교도가 증가함을 확인하였다. 그리고 함수율, 화학적 안정성, 기계적 물성 측정을 통해 가교제 함량에 따른 영향을 평가하였고, 가교구조의 도입으로 인하여 제조된 막의 함수율, 화학적 안정성, 기계적 물성이 향상되었음을 확인하였다. 또한 전기화학적 분석을 통하여 막의 면적저항을 측정한 결과, 가교도의 증가로 인해 막 면적저항이 증가함을 확인하였다. In this study, crosslinked SPS/TMPETA membranes were fabricated by solution casting of various compositions of sulfonated polystyrene (SPS) prepared by sulfonation of polystyrene (PS) and trimethylolpropane ethoxylate triacrylate (TMPETA) crosslinker followed by an electron beam irradiation. We confirmed that SPS polymer was successfully prepared by the introduction of sulfonic acid group in PS from the results of FTIR analysis and measurement of sulfonation degree. The degree of crosslinking of the prepared membranes increased with an increase in absorption doses and crosslinker contents, which was obtained by measuring gel fraction. The effects of the crosslinker contents were estimated by measuring water uptake, chemical stability, and mechanical properties of the prepared membranes. It was confirmed that the introduction of crosslinked structures in SPS membranes improved the water uptake, chemical stability, and tensile strength. Also, the results of the electrochemical analysis showed that membrane area resistance increased with an increase in the degree of crosslinking.

Korean traditional woman’s opera was a traditional drama style with classical pansori and traditional dance, and dominated theaters nationwide as an icon of Korean performing arts until the early 1960s. Kim Kyung-soo was the most popular star actress, succeeding Im Chun-ang, a leading male character actress in the Korean traditional woman’s opera industry. This study researched Kim Kyung-soo and his own specialized performance style, which was at the height of the Korean traditional woman’s opera. Kim Kyung-soo did not receive systematic or traditional apprenticeship education, but underwent a harsh education based on Im Chun-ang’s outstanding artistic talent and was skilled enough to become a star. The Jingyeong Women’s Opera Company performed the following on stage: <Love Tower>, <Before Flowers>, <The covenant>, <Goodbye without promise>, <Star>, <Lost in the Palace>, <Lost in the Early Night>, <Love Imagination Stick>, <The Throne>, <Lulu Crown Prince>, <Kanghwadoryeong>. Kim Kyung-soo dressed up in exaggerated costumes, wore red-toned face makeup, thick eyebrows and sideburns, cotton on his shoulders, or high shoes, emphasized his body shape with clothes attached to his body, focused more on content delivery than Im Chun-ang, and danced dramatically. These components were in line with the needs of the public. This study enabled us to find the reasons for the success of Kim Kyung-soo and the Korean traditional woman’s opera.

본 연구는 2019 프랑스 여자 월드컵과 2023 호주 뉴질랜드 여자 월드컵의 8강 진출팀을 대상으로, 경기 활동량(체력) 관련 변수들에 대한 비교 분석을 실시하였다. 대상은 각 경기에서 70분 이상 출전한 수비수(DF), 미드필더(MF), 공격수(FW) 포지션의 선수 411명으로, 골키퍼는 분석에서 제외되었다. 본 연구는 SPSS 27.0 통계 패키지를 활용하여 분석을 수행하였으며, 평균(M) 및 표준편차(SD)를 산출하고, 일원배치 분산분석(One-way ANOVA) 및 Scheffe 사후 검증을 통해 경기 활동량 데이터 간의 차이를 분석하였다. 또한, 대회별 활동 유형 및 체력 분석을 위해 이원배치 분산분석(Two-way ANOVA) 및 Scheffe 사후 검증을 실시하였다. 분석 결과, 구역 1 이동거리(0-7km) 및 구역 3 이동거리(13-19km)에서의 이동 거리는 2019년 대회에서 더 높았으며, 구역 5 전력질주 횟수(>23km)에서의 횟수는 2023년 대회에서 증가하였다는 점이 확인되었다. 이는 2019년 대회에 비해 2023년 대회에서 포지션별 역할과 전술적 요구가 변화하였음을 시사한다. 특히, 공격 전환 및 역습 상황에서의 역할 변화가 포지션별 체력적 요구사항에 변화를 유발하였다는 점에서 주목할 만하다. 본 연구를 통해 얻어진 결과는 두 대회 간의 체력적 변화 및 전술적 진화를 이해하는 데 기여할 뿐만 아니라, 향후 대회 준비 및 선수 개발 전략 수립에 있어 중요한 시사점을 제공한다. 또한, 대회별 및 포지션별 체력 데이터의 비교를 통해 얻은 결과는 여자 축구의 전술적 및 체력적 준비에 있어 지속적인 개선을 위한 기초자료로 활용될 것이다. This study conducted a comparative analysis of the physical activity variables of the teams that reached the quarter-finals in the 2019 France Women’s World Cup and the 2023 Australia New Zealand Women’s World Cup. The subjects were 411 players from the positions of defender (DF), midfielder (MF), and forward (FW) who played more than 70 minutes per game, excluding goalkeepers from the analysis. The study utilized the SPSS 27.0 statistical package for analysis, calculating means (M) and standard deviations (SD), and conducted one-way analysis of variance (One-way ANOVA) and Scheffe’s post-hoc test to analyze differences in physical activity data. Additionally, a two-way analysis of variance (Two-way ANOVA) and Scheffe’s post-hoc test were conducted to analyze activity types and physical levels by tournament. The analysis revealed that the distance covered in zone 1 (0-7km) and zone 3 (13-19km) was higher in the 2019 tournament, while the number of high-intensity sprints in zone 5 (>23km) increased in the 2023 tournament. This suggests that the role and tactical demands on positions changed from the 2019 to the 2023 tournament. Notably, changes in roles during attack transitions and counter-attacks induced changes in physical demands by position. The findings of this study not only contribute to understanding the physical and tactical evolution between the two tournaments but also provide important insights for future tournament preparations and player development strategies. Moreover, the comparison of physical data by tournament and position can serve as a foundational resource for continuous improvement in tactical and physical preparation in women’s soccer.

Capillary hemangioma of the trachea is an extremely rare benign tumor in adults. We present the case of a 28-year-old woman with hemoptysis owing to a tumor of the proximal trachea. The tumor was removed by rigid bronchoscopy. The resulting specimens showed capillary hemangioma without any signs of malignant transformation. This presentation is the first case in Korea. Although tracheal capillary hemangioma is a rare disease, we should consider it as a possible cause of hemoptysis in the young adult.
