This study aimed to investigate the narrative strategy and meaning of fantasy in classic novels and to derive the educational meaning from the fantasy of Sukhyangjeon. This study selected Sukhyangjeon because is considered a suitable literary text that embodies characteristics of fantasy inherent in classical novels through its successful portrayal of the fantasy genre and its high popularity during its time. Specifically, this study observed that the "notice of hardships" which repeatedly appears in the narration of Sukhyangjeon reinforces the fantasy of the novel as it serves as an advance notice of intervention from heaven. Therefore, this study investigated the relationship between the notice of hardships and fantasy by focusing on Sukhyang's life. The way in which the "notice of hardships" is a form of illusion realized it evident in the plot when heaven saves Sukhyang from her hardship even though it was heaven that had granted her those forms of hardship. Firstly, the "notice from heaven" constitutes the macro structure of Sukhyangjeon. Through it, readers realize the enormous power of heaven by seeing how Sukhyang's life has been realized in accordance with heaven's notice with that, it evokes a sense of respect to heaven. In addition, heaven saves Sukhyang from different forms of danger. It enhances a miraculous feeling, which the omnipotent power of heaven shows, against the innocent appearance of Sukhyang during her times of danger. Meanwhile, when heaven notifies Sukhyang and the surrounding people of their fate and subsequently realizes it through dreams, this act creates a mysterious atmosphere and improves the probability of the narrative. If so, the narrative meaning in reinforcing the fantasy of the novel by the use of "notice of hardships" could be revealed through Sukhyang's real life. First, the hardship in which Sukhyang has gone through is so realistic and detailed that the readers' feelings of empathy are evoked with the fear of the coming hardship, wailing together, and trying to resolve the inner anxiety through Sukhyang's happiness. Second, the heavenly beings who are touched by the good behaviors of Sukhyang save her from the dangers of death. This creates the belief in readers that heaven intervenes for the good people. Third, the active attitude that Sukhyang and Leesun show in the process of marriage helps them overcome their earthly hardship and preserve their relationship in heaven. This gives readers hope that they could go to a "higher life" after going through suffering. This fantasy of Sukhyangjeon helps readers overcome their anxieties of reality through fantasy and recognizes the importance of relationships to enhance a sense of unity and solidarity with others. Because of these elements, it is expected that the fantasy of Sukhyangjeon will have a meaningful value to modern readers.

In this paper, we propose both a new loss function and an online hard example mining scheme for improving the performance of single-stage object detectors which use deep convolutional neural networks. The proposed loss function and the online hard example mining scheme can not only overcome the problem of imbalance between the number of annotated objects and the number of background examples, but also improve the localization accuracy of each object. Therefore, the loss function and the mining scheme can provide intrinsically fast single-stage detectors with detection performance higher than or similar to that of two-stage detectors. In experiments conducted with the PASCAL VOC 2007 benchmark dataset, we show that the proposed loss function and the online hard example mining scheme can improve the performance of single-stage object detectors.

기존 할로겐프리 제품은 PVC와 비교하여 유연성이 크게 떨어져 PVC 사용에 대한 규제가 강화되고 있음에도 불구하고, 이를 쉽게 대체하기 곤란하다는 문제점이 있다. 이에 할로겐프리 재료만 사용하여 고난연성, 예를 들면 UL 1581 에 따른 VW-1 규정을 충족하는 고난연성을 가지면서도 경도가 낮아(경도 70수준, Shore A) 재질의 유연성이 확보된 고분자 재료를 개발하는 것이 요구된다. 실험 결과로부터 인장강도 11[Mpa], 신장율 720[%], 가열후 인장강도 잔율 90[%], 가열후 신장잔율 88[%], 산소지수 38.0, 수직난연시험 합격, 경도(Shore A) 70, 백화현상이 나타나지 않는 등 우수한 특성을 보였다.

The role of bass in band or ensemble music literally sets up the foundation of harmony, which must be regarded first. On the other hand, this is also considered so basic or stable that it can be slightly boring to the listeners. Consideration is needed to make the varied trials more exciting. In this sense, Rutger Gunnarsson showed these fine examples not in performing music but in pop music through the Great ABBA. He could make a fabulous sound with only a basic performance, not with a florid technique or rhetorical skills. All bassists must bear in mind that the overall performance depends on the bass. In short, to make better music, remember to practice continually and find better methods.

Background: Pneumonectomy for inflammatory lung disease has been of major concern because of its associated morbidity and mortality, particularly with respect to pleuropneumonectomy. The purpose of this study is to evaluate the surgical outcomes, and identify the risk factors contributing to postoperative complications in patients undergoing pleuropneumonectomy. Material and Method: Ninety-eight patients underwent pneumonectomy for benign inflammatory lung disease were retrospectively analyzed. Pleuropneumonectomy (Group A) was done in 48 patients and standard pneumonectomy (Group B) was done in 50 patients. Clinical characteristics, postoperative complications were examined and compared between 2 groups. In pleuropneumonectomy group, postoperative risk factors affecting morbidity were evaluated. Result: There was one in-hospital death. Twenty-three major postoperative complications occurred in 21 patients (21.4%). The common complications were empyema and bronchopieural fistula (BPF) in 8 (8.4%), re-exploration due to bleeding in 8. At least one postoperative complication occurred in 14 of 48 patients from Group A (29.2%) and in 7 of 50 patients from Group B (14%). In Group A, empyema and BPF encountered in 6 and re-exploration for bleeding in 6 were the most common complication. In univariate analysis, right pneumonectomy, completion pneumonectomy, large amount of blood loss (>1,000 mL), and intrapleural spillage were risk factors contributing to postoperative complications in Group A. In multivariate analysis, intrapleural contamination during operation was a risk factor of postoperative complication. Conclusion: The morbidity and mortality rates of pneumonectomy for chronic inflammatory lung disease are acceptably. However, we confirm that pleuropneumonectomy is a real technical challenge and a high-risk procedure and technically demanding. Meticulous surgical techniques are very important in preventing serious and potentially lethal complications.

This study explores the creation and enjoyment of Kuwoonmong (九雲夢) using a reference system called the cultural imagination, which is related to the Yin-Yang (陰陽) and Wu Xing (五行). When Kim Manjung wrote Guwoonmong, he may have composed figures and events based on this imagination. In particular, when he designed the eight seonnyeo (팔선녀), he set the order such as Gap (甲), Eul (乙), Byeong (병), Jeong (丁), etc. and characterized them according to the celestial stem (天干). Thus it was easy to avoid overlapping of characters and to construct various stories and relationships between them. The table below shows the characters of Kuwoonmong corresponding to the celestial stem. In not only the individual person but also the narrative world, Kuwoonmon demonstrates Yin-Yang and Wu Xing's imagination. In this respect, Kuwoonmon can be considered a large symbol encompassing the abstract theory of Yin-Yang and Wu Xing. Of course, the writer, Kim, Manjung would not have tried to symbolize the principle intentionally. However, he was also present in the environment of the cultural imagination that has been formed over the years. The same is true for the contemporary recipients of Guwunmong. They would have had a pleasant experience applying the cultural imagination and strengthening their familiar world view and human view.
