        본 논문은 현대 세속적 맥락 속에서 예이츠의 􋺷연옥􋺸에 나타난 내재성 과 초월성의 불안한 결합을 탐구한다. 찰스 테일러의 “내재적 틀” 개념은 자족적인 자 연 질서 내에서 세계를 인식하는 현대적인 방식을 설명하기 위해 인용된다. 동시에, 내재적 틀은 초월성에 열려 있으며 다양한 형태의 신념이 등장할 수 있는 여지를 제 공한다. 이러한 새로운 관점은 예이츠가 􋺷연옥􋺸에서 묘사한 독특한 구상의 의미를 밝 히는 데 도움이 될 수 있으며, 이는 영적 구원이 거부되는 세계 속에서 자기복제적인 후회가 반복되는 순환으로 나타난다. 본 논문은 이 극의 극단적인 미니멀리즘, 물질적 현실에 대한 집중, 세대를 넘는 트라우마에 대한 탐색을 분석함으로써, 예이츠가 자연 과 초자연, 내재성과 초월성의 경계를 넘나들며, 결국 초월에 대한 욕망이 우리의 내 재적 틀과 분리될 수 없음을 드러낸다고 주장한다.

        Given the hazards posed by black ice, it is crucial to investigate the conditions that contribute to its formation. Two ensemble machinelearning algorithms, Random Forest (RF) and Extreme Gradient Boosting (XGBoost), were employed to forecast the occurrence of black ice using atmospheric data. Additionally, explainable artificial intelligence techniques, including Feature Importance (FI) and partial dependence Plot (PDP), were utilized to identify atmospheric conditions that significantly increase the likelihood of black ice formation. The machinelearning algorithms achieved a forecasting accuracy of 90%, demonstrating reliable performance. FI analysis revealed distinct key predictors between the algorithms: relative humidity was the most critical for RF, whereas wind speed was paramount for XGBoost. The PDP analysis identified the specific atmospheric conditions under which black ice was likely to form. This study provides detailed insights into the atmospheric precursors of frost/fog-induced black ice formation. These findings enable road managers to implement proactive winter road maintenance strategies, such as optimizing anti-icing patrol routes and displaying warnings on various message signs, thereby enhancing road safety.

        Background: Aquatic exercise utilizing hot springs helps individuals with nonspecific knee pain by reducing joint stress and providing a safe environment for movement. It can improve muscle strength and balance, enhancing overall functional mobility. Objects: This study aims to examine the muscle strength of knee flexion, knee extension, dorsiflexion, and plantar flexion, as well as to investigate static and dynamic balance in middleaged females after performing hot spring aquatic exercise for 4 weeks. Methods: Twenty-two middle-aged females participated in the study. The participants performed hot spring aquatic exercise for 4 weeks. The hot spring aquatic exercise consisted of aquatic walking, aquatic stretching, aquatic side step, aquatic forward reach, aquatic squat, leg lift, and aquatic arm and leg rotation. Muscle strength was measured using microFET2, while static balance was assessed through the one-leg stance test, and dynamic balance was evaluated using the Y-balance test. This study utilized the paired t-test for statistical analysis, with a significance level set at 0.05. Results: The muscle strength of bilateral knee flexion showed a significant increase in the pre- and post-comparison (p < 0.05), and the muscle strength of bilateral knee extension also improved significantly (p < 0.05). In addition, a significant increase was observed in the muscle strength of bilateral dorsiflexion (p < 0.05). The one-leg stance test performed while supporting on the right leg showed a significant increase in the pre- and post-comparison (p < 0.05). Furthermore, the dynamic balance measurements performed while supporting on both the right and left legs demonstrated significant improvements in both legs when compared before and after the intervention (p < 0.05). Conclusion: In individuals with nonspecific knee pain, a 4-week hot spring aquatic exercise program can contribute to the improvement of lower extremity strength, as well as static and dynamic balance ability.

        Sweetpotato (Ipomoea batatas L.) is a globally important food crop susceptible to root-knot nematode (Meloidogyne incognita) infection, which causes significant crop losses. Previous transcriptome and proteome analyses have identified several genes that show differential expression patterns in susceptible and resistant cultivars in response to root-knot nematode (RKN) infection. Among the genes responsive to this process, sporamin (SPO) genes were identified as the most abundant in the transcriptome analysis, and additional changes in the expression of SPO genes that showed specific responses to RKN infection were identified during nematode infection. In this study, we used SPO genes used in previous studies to identify expression patterns under various abiotic stress conditions. The expression of four SPO genes in sweetpotato leaves was investigated under conditions of drought, high salt, and stress-related chemicals treatment. The expression of G13675/TU22356, G34367/TU56356, and G34382/TU56395 increased similarly under dehydration and chemicals treatment conditions. On the other hand, G34367/TU56358 was constantly expressed during the stress treated conditions. This study is expected to be used as basic data on how the gene for the major protein SPO of sweetpotato responds to various abiotic stress conditions as well as nematode infection.
