  • Elderly patients with acute subdural hematomas have higher mortality and lower functional recovery rates compared with those of other head-injured patients. Early and widely surgical decompression and active intensive care represent the best way to assist these patients. However, abrupt decompression of the hematoma can lead to brain disruption and secondary ischemia in the brain surrounding the craniectomy site. Acute brain swelling and brain extrusion, which take place shortly after decompression, can lead to a catastrophic situation during the operation due to the impossibility of appropriate closure of the dura and scalp. To avoid the deleterious consequences of disruption of brain tissue, we have adopted multiple fenestrations of the dura in a mesh-like fashion and gradual release of subdural clots through the small dural openings that are left open. This is especially important in cases in which there are massive amount of subdural hematomas with small parenchymal lesion and severe midline shifts in elderly patients. Further clinical experiences should be conducted in a more selected series patients to estimate the impact of this technique on morbidity and mortality rates.

  • Fretting is a kind of surface degradation mechanism observed in mechanical components and structures. The fretting damage decreases into 50-70% of the plain fatigue strength. The connecting rod for automobile has been used in special environments and various loading conditions. Failure of connecting rod in automotive engine may cause catastrophic situation. In this study, we investigated the fatigue characteristic of connecting rod material for an automobile. Fatigue life is defined as the number of cyclic stress to failure by regular cyclic stress. Fatigue life of C70S6 specimen was obtained from 134,000 to 147,000 cycles. Fatigue limit showed 432MPa by normal fatigue test. The other hands, it was 96MPa in the case of fretting fatigue test. It was extremely lower than that of a normal fatigue test. From observation of fracture surface, it was confirmed that the fatigue crack was initiated at the boundary of a specimen and bridge pad.

  • In terms of element and process, art today has already been fully systemized, yet tends to become even more systemized. All phases of creation and exhibition, appreciation and education, promotion and marketing are planned, adjusted, and decided within the order of a globalized, networked system. Each phase is executed, depending on the system of management and control and diverse means corresponding to the system. From the step of education, artists are guided to determine their styles and not be motivated by their desire to become star artists or running counter to mainstream tendency and fashion. In the process of planning an exhibition, the level of artist awareness is considered more significant than work quality. It is impossible to avoid such systems and institutions today. No one can escape or be freed from the influence of such system. This discussion addresses a serious distortion in the selection system as part of the system connotatively called "art museum system," especially to evaluate artistic achievement and aesthetic quality. Called "studio system" or "art star system," the system distinguishes successful minority from failed absolute majority and justifies the results, deciding discriminative compensations. The discussion begins from work by Hunter Jonakin and Dan Perjovschi. The key point of this discussion is not their art worlds but the shared truth referred by the two as the collusive "art market" and "art star system." Through works based on their experiences, the two artists refer to these systems which restrict and confine them. Jonakin's Jeff Koons Must Die! is avideo game conveying a critical comment on authoritative operation of the museum system and star system. In this work, participants, whether viewer or artist, are destined to lose: the game is unwinnable. Players take the role of a person locked in a museum where artist Jeff Koons' retrospective is held. The player can either look around and quietly observe the works, which causes a game-over, or he can blow the classical paintings to pieces and cause the artist Koons to come out and reprimand the player, also resulting in a game-over. Like Jonakin, Dan Perjovschi's some drawings also focuses on the status of the artist shrunken by the system. Most artists are ruined in a process of competition to survive within the museum system. As John Burger properly pointed out, out of the art systems today, public collections (art museums) and private collections have become "something unbearable." The system justifies the selection system of art stars and its frame of reference, disregarding the problem of producing numerable victims in its process. What should be underlined above all else is that the present selection system seriously shrinks art's creative function and its function of generating meaning. In this situation, art might fall to the level of entertainment, accessible to more people and compromising with popularity. This discussion is based on assumption and consciousness on the matter that this situation might cause catastrophic results for not only explicit victims of the system but also winners, or ones defined as winners. The system of art is probably possible only by desire or distortion stemmed from such desire. The system can be flourished only under the economic system of avarice: quantitatively expanding economy, abundant style, resort economy in Venice and Miami, and luxurious shopping malls with up-to-date facilities. The catastrophe here is ongoing, not a sudden emergence, and dynamic, leading the system itself to a devastating end.

  • 한반도는 탈냉전이라는 역사적 변화에도 불구하고 냉전적 구조가 해제되지 않고 북한의 대남도발은 계속되고 있다. 북한의 천안함 폭침과 연평도 포격도발은 파국적인 남북관계 초래와 동북아 불안정의 요인으로 작용하고 있다. 북한의 도발은 미국과 한국 및 북한 내부 요인이 북한의 의사결정체계에서 복합적으로 작용하여 군사 비군사적 수단에 의해 자행되고 있다. 북한은 한반도의 적화통일이라는 전략기조을 유지하기 때문에 공세적으로 지속될 수밖에 없을 것이다. 북한의 대외정책은 지속성과 상황에 따라 변화하는 양면성을 지니고 있다. 북한 대외정책의 목표와 이념은 비교적 일관성 있게 지속하고 있지만, 정책전개의 전략 전술과 행동 유형에서는 상당한 변화가 있다. 즉, 지속성은 곧 국가 체제유지와 국가 생존 명분의 문제이며, 변화는 지속성과 명분을 유지시키고 발전하기 위한 전술적 종속개념에 해당한다. 합리적인 시각으로 본다면 북한의 대외정책 기조는 군사력과 핵무기 개발을 생존수단으로 삼아 긴장을 조성하여 외교적, 경제적 보상을 얻는 외교방식을 과감하게 탈피하여야 하며 국제사회에 참여하여 하나의 국가로서 국제관례를 지키는 자세를 견지해야 하나 여러 가지 여건상 기존 대외정책 방향을 고수하고 있다.

  • Purpose: The purpose of this qualitative study is to explore the changed parenting experiences of mothers of elementary school kids living in the aftermath of the COVID-19 outbreak in Korea. Methods: From July to August in 2020, 10 mothers parenting elementary school students under the COVID-19 were interviewed in depth. For data analysis, a phenomenological research methodology suggested by Colaizzi was used. Results: According to the analysis, the experiences of mothers consisted of four categories: the 'pain from the uncontrollable COVID-19', 'the problem of family relations due to the COVID-19 pandemic situation', 'standing firm against the drastic changes', and 'accepting the world changed by the COVID-19'. Conclusion: The findings in this study vividly represent the parenting experiences of mothers of elementary school students after the outbreak of COVID-19. As the pandemic persists, mothers parenting elementary school students feel complex emotions and experience exhaustion, but in the process, they found family members growing positively and trying to adjust to each other to overcome the crisis. To support positive adaptation to catastrophic situations, an institutional and political foundation is needed to develop a systematic crisis management program customized for mothers and families of elementary school students. The results of this study can be used as basic data when establishing national policies and support systems so that mothers parenting elementary school students can better adapt to and overcome crisis situations.

  • War films are a general term for films that have battlefields as their main background. Although war films as a genre directly deal with combat situations, they also deal with characters or subjects related to war. War films promote patriotism and nationalism, but they also argue against war by highlighting the disastrous war. This study is based on the color theory that the meaning of film color is temporarily and infinitely generated according to the cultural differences, with Eisenstein's creative theory on film color and pathos. I wanted to clarify the pathos effect and the meaning of color green expressed in the Korean war films. In war films, colors are visualized in art forms such as symbols, similes and metaphors. In war films, color green symbolizes life. On the battlefield, the green of nature stands against the catastrophic situation. The green of ecology, which insists on the flow of life, evokes fear in ecological crises such as war, disaster and climate change. The dark green caused by a catastrophe like war warns of the destruction of life. The connotation of color is temporarily and infinitely expands according to the cultural differences. The dark green, which visualizes the battlefield of destruction, is a form and element of pathos that indicates changes in emotions such as sadness, pity, grief and despair. Pathos as an emotional appeal is a leap from the quality to the quality of the means of expression and refers to the departure from Dasein. The green color that dominates the visuals of war films is a symbol of life and functions as a pathos that makes emotional changes take a new leap. A qualitative leap through pathos means all changes that become new.

  • 대공황은 20세기의 가장 중요한 역사적 사건 중 하나로, 현재 고등학교 사회과 교과서들은 근대 경제의 형성과 관련해서 대공황을 비중 있게 다루고 있다. 하지만 대공황에 대한 교과서의 서술들을 분석해 보면, 부실한 논리 전개나 틀린 사실의 수록, 나아가 교육적으로 부적절한 표현들을 실은 사례가 다수 발견된다. 궁극적으로는 교과서들이 제시하고 있는 대공황에 대한 목적론적 해석, 즉 자유방임주의 혹은 시장의 본원적 불안정성으로 인해 과잉생산이 초래되어 대공황이 발생하였으며, 국가개입을 통해 대공황이 해소되었다는 해석 자체가 경제사학자들의 연구 결과와 부합하지 않는다. 사회와 역사에 대한 균형 잡힌 인식의 함양이라는 사회교과의 목적을 위해서는 대공황에 대한 서술을 근본적으로 개선하는 작업이 요구된다.
