This study is to search a meaning of treagedy to show by the 6th generation through charecter's tragedy in the 6'th Generation Chinese film. For this, it examined an inner characteristic behind of the tragedy's moment and externalized ending in directors' films of the 6'th Generation's representation. The 6'th Generation of Chinese film reorganized newly Chinese film's cultural topography in the 1990s. The 6'th Generation films, which rebelled against the primary melody and the 5'th Generation on the system, is expressed commonly a tragedy moment with the time and space by character's tragedy. Characters of the 6'th Generation in the tragedy moment attempts various efforts to escape from the tragedy moment. However, no one can overcome the wall of reality, and their concealed emotion as keeping it out of the public eye lead that play. The moment that the 6th generation film meets a tragedy, the main character's accumulated tragedy situations begin to unfold all together. A tragedy embodied through : a collapsed tragedy due to the past's wound, a tragedy due to loss of jobs, a tragedy due to a family's departure, a tragedy from a time of chaos, a tragedy of a woman who became a head of a household and other tragedies.

My former thesis was about the present status of Korean film aesthetics of Korean blockbusters through the cultural hybridity. Now this thesis focuses on hybridity and tragedy in Korean blockbusters from the postcolonial perspectives. Typical examples are Shiri, JSA, Taegukgi containing a special Korean situation of division ideology and expressing an extremely Western style of production. These movies hardly provide any historical causes, critical explanation, or vision beyond the discourse of national tragedy. They simply supply sentimental feeling of sympathizing with the misfortune of heroes in the course of national suffering. Therefore, these movies shows limitation not to accomplish postcolonial resistance.

Insecticidal potentials of polar and non-polar tractions obtained from 84 medicinal plants were screened against five major agricultural insects. Based on the primary and secondary screening results, non-polar fraction of Atractylodes koreana Kitam. rhizomes was selected to isolate and identify an active compound effective to diamondback moth (Plutella xylostella L.) larvae. Counter-current distribution separation on the non-polar fraction and TLC and spectroscopic analyses (GC-MS and $^{1}H$- and $^{13}C$-NMR) revealed that molecular formula of the active compound was $C_{15}H_{22}O$ known as a sesquiterpenoid 4,11-selinadien-3-one (${\alpha}$-cyperone). However, ${\alpha}$-cyperone was not detected in the non-polar fractions that showed high insecticidal potential against the diamondback moth. Although ${\alpha}$-cyperone has been first identified from Cyperus rotundus, the compound did not occur in C. rotundus cultivated in Korea.

최근 들어 지표면 오존농도의 증가에 기여하는 오존전구물질에 대한 관심이 증대되면서 오존전구물질에 대한 분석방법의 확립에 많은 노력을 기울이고 있는 실정이다. 지금까지는 비극성 column을 이용하여 저온 농축과정을 거쳐 분석을 수행하거나 극성 및 비극성 column을 병렬로 연결하여 환경대기 중의 오존전구물질을 측정한 연구사례가 대부분인 것으로 보고되고 있으나 이러한 저온농축과정 및 다수의 column을 사용할 경우 소요되는 장비 및 시간에 대한 비경제적인 측면을 고려하지 않을 수 없다. (중략)

Water in the supercritical state ($T{\geq}374^{\circ}C$, $p{\geq}221$ atm) is a good solvent for nonorganic pollutants, but it is extremely corrosive. Subcritical Water Extraction (SWE) is a very fast and an efficient method to extract nonpolar environmental pollutants adsorbed on the sediments and soils. Many nonpolar organic compounds are sufficiently soluble to be extracted to the water under subcritical conditions. Complete extraction of PCBs from the sediments and soils takes only a few minutes by applying SWE with the subcritical water at 50 atm and at $260^{\circ}C$.

This research analyzes the characteristics of Chinese tragic films with Chinese traditional ethical ideology as the core, analyzes its specific performance in the plot and ending setting of the film , and analyzes the director's tragic narrative strategy of cultural reconciliation in the face of political environment to understand the characteristics of Chinese contemporary tragic films.The film is a Chinese contemporary tragic film with The Great Cultural Revolution as its historical background. This film is a representative film of Chinese contemporary tragic films. The classic plot has played a certain role in the expression of Chinese traditional ethical ideology such as fatalism and optimistic attitude to life. The male lead's thought changes interpret the Chinese-style tragedy characteristics containing Chinese traditional ethical ideology. In the setting of the ending, the film broke through the "happy ending" model of Chinese traditional tragedies, and chose the open ending of "one tragedy to the end", further showing the time feature of Chinese contemporary tragic film. The euphemism and tenderness of the film as a tragic film is not only due to the compromise with the political culture of power, but also the result of the director's in-depth understanding of the aesthetics of Chinese tragedy. Through the use of symbolic signs in the film language, it has formed the implicit characteristics of the film narrative in the tragic aesthetic experience. In this paper, the author conducts text analysis for the film and discusses presentation of Director Yimou Zhang's tragic feelings and using the tragic narrative strategy of cultural reconciliation to show his creative wisdom in pursuing artistic breakthroughs under political pressure.

La estrella de Sevilla, is a representative masterpiece of the Golden Age of Spain, and is a tragic work of Lope de Vega, who was a representative drama writer living in the 17th century. However, regardless of its great literary value, there are insufficient researches on this drama even in Spain, due to several controversies surrounding the truth about Lope's creation. Here, this research concretely investigated the tragic characteristic of this drama, by largely dividing it into the viewpoint of Aristotle and Shakespeare. Thanks to the noble social status of the characters and proper dialogue of the hero Sancho Ortiz in trouble, there seems to be no problem in performing the cathartic function that Aristotle mentioned regarding the work in his review. However, there are a few problems in the aspect of the 'hero's free will to resist the absolute fate,' which is fundamentally the essence of the associated Aristotelian tragedy. Because, there's no Hamartia in this drama, the core mechanism that forms the absolute fate, makes the statement that accordingly, no absolute fate or irresistible force of destiny is established. Rather, the tragic characteristic of this drama can be more properly investigated from the viewpoint of Shakespeare. As noted differently from Aristotle, Shakespeare considered that the tragic characteristic came from the hero's characteristic. According to him, tragedy starts from the hero's value view and personality, instead of the external factors such as an absolute fate. Actually, Busto's death and separation between Sancho Ortiz and Estrella, two tragic affairs of La estrella de Sevilla, were caused by the crooked selfishness of King Sancho IV, who abused his authority, and Sancho Ortiz' excessively blind loyalty to the King, rather than the irresistible event. In conclusion, in light of a lethargic and hopeless situation, with no eventual choice of options before the injustice of absolute power, is must have been a significant tragedy for the audience, witnessing the play's tragic ending.

극성 [0001] 방향으로 성장된 질화물 기반의 LED (light emitting diode) 는 분극현상에 의해 발생하는 강한 내부 전기장의 영향을 받게 된다. 이러한 내부 전기장은 양자우물 내의 전자와 정공의 공간적 분리를 야기하고 quantum confined Stark effect (QCSE)에 의한 발광 파장의 적색 편이가 발생하며 양자효율의 저하를 가져오게 된다. 이러한 문제를 해결하기 위해 InGaN/GaN이나 AlGaN/GaN 양자 우물구조를 GaN의 m-plane (1$\bar{1}$00) 이나 a-plane (11$\bar{2}$0) 등 비극성면 위에 성장하려는 시도를 하고 있다. 그러나 비극성 면의 비등방성 (anisotropy) 으로 인하여 결정성이 높은 비극성 GaN을 성장하는 데에는 많은 어려움이 있다. GaN 층의 표면을 평탄화하고 결정성을 향상시키기 위해서 저온 GaN 또는 AlN 버퍼층을 성장하는 2단계 방법이나 고온 버퍼층을 이용하여 성장하는 연구들이 많이 진행되고 있다. 본 연구에서는 고온 GaN 버퍼층을 이용하여 기존의 2단계 성장과정을 단순화한 비극성 a-plane GaN을 r-plane 사파이어 기판위에 유기금속 화학증착법 (MOCVD)으로 성장하였다. 사파이어 기판위에 AlN 층을 형성하기 위한 nitridation 과정 후 1030 도에서 두께 45 ~ 800 nm의 고온 GaN 버퍼층을 성장하고 총 박막 두께가 2.7 ~ 3 um 가 되도록 a-plane GaN을 성장하여 표면 양상의 변화와 결정성을 확인하였다. 또한 a-plane GaN 박막 성장 시에 성장 압력을 100 ~ 300 torr 로 조절하며 박막 성장의 변화 양상을 관찰하였다. 고온 GaN 버퍼층 성장 두께가 감소함에 따라 결정성은 증가하였으나 표면의 삼각형 형태의 pit 밀도가 증가함을 확인하였다. 또한 성장 압력이 감소함에 따라 표면 pit은 감소하였으나 결정성도 감소하는 것을 확인하였다. 성장 압력과 버퍼층 성장 두께를 조절하여 표면에 삼각형 형태의 pit이 존재하지 않는 RMS roughness 0.99 nm, 관통전위밀도 $1.78\;{\times}\;10^{10}/cm^2$, XRD 반가폭이 [0001], [1$\bar{1}$00] 방향으로 각 798, 1909 arcsec 인 a-plane GaN을 성장하였다. 이 연구를 통해 고온 GaN 버퍼 성장방법을 이용하여 간소화된 공정으로 LED 소자 제작에 사용할 수 있는 결정성 높은 a-plane GaN을 성장할 수 있는 가능성을 확인하였다.

Using FT-IR and contact angle measurements it is observed that the chemical surface treatments on virgin carbon blacks lead to a change of the surface properties, including surface functionality and surface free energy It is found that the developments of surface functional groups on acidically and basically treated (ACB and BCB in this study, respectively) carbon blacks are largely correlated with the specific component of surface free energy of the carbon blacks. However, a significant advantage of compounding composites is gained by BCB or NCB (nonpolar chemical treatment) specimens, resulting in improving the hardness, elongation at break, and tensile strength. Particularly, it is seen that the tensile strength of the composites are greatly depended on the London dispersive component of surface free energy determined from the contact angle measurements. It is then concluded that the London dispersion component of carbon blacks plays an important role in an organic rubbers-based compounding composite system.

In this paper, I try to interpret a new interpretation of the tragedy of the work related to the affection of the male and female protagonists in , and to examine what the author Lee-Ok wanted to accomplish through his work. To do this, I first looked at the viewpoints of love between men and women. The writer insisted that there was nothing to observe the love of man and woman to observe all things of heaven and earth. And this is because he considered love of man and woman as true love. In addition, this study examined the personality of the male and female main character and the woman. Through this, the male and female protagonists of announced that they were willing to solve the affection problem positively according to the situation given to them. Based on these discussions, I have shown that the tragic nature of the is due to the frustration of the male and female protagonists despite their active affection. Therefore, through the love stories of male and female protagonists, suggests that the love of men and women is closely related to ordinary and everyday problems such as unexpected diseases, as well as social problems surrounding the two. And it is an exquisite work of narration of the genuine truth. In the end, the author Lee-Ok tried to present the inner scenery of human beings through the that the problem of affection between men and women can not be solved by human will and can be frustrated by any unexpected contingency or unexpectedness There will be.
