This study is to analyze T. E. Hulme's thought and aethetics which seem to exercise agreat influenve upon the current of twentienth-century English poetry. The most striking fact in twentienth-century English literary history is the revolution in poetic taste and practice. T. S. Eliot and Ezra Pound were in large measure its leaders but much of the theoretical combat was supplied by T. E. Hulme who, before his death in the war in 1917, had declared war on the Romantic view of life and art. Hulme wanted discipline, precision, "the exact curve of the thing," "dry hardness," classicism. Hulme produced a collocation of classicism, the "religious" attitude, abstract or geometrical art, belief in original sin, and hard, clear and precise images. He also offered opposition to romanticism, humansim, naturalistic art, belief in man's unlimited potentialities, the emotional and soft, the Renaissance attitude and self-expression.

We review various microscopic mechamisms that have been proposed to explain Schottky barriers and Fermi - level pinning, and extent their mechanisms are compatible with the experimental data. The central role of interface states and their different physical origins are discussed. A particular interface system Si/NiSi_(2) is investigated in detail.

One of the most important Problem in three-dimensional motion is that of a mass moving under the action of a central force inversely proportional to the square of the distance from the center. The conservation laws for angular momentum and energy are consequences of the large degree of symmetry. Actually exploring symmetries and their consequences is essential in the search for the laws of physics. The central force problem is good example for investigations of symmetries and conservation laws. Although some difficulties ate expected making high school students understand. it seems desirable to give them a flirty good intuitive feeling for the connection between symmetries and conservation laws.

표면 및 계면에서의 electronic structure에 대한 정보를 tight-binding 방법에 의하여 결정된 Green's function으로부터 이끌어 낼 수 있음을 검토한 후 Si/CoSi_(2) (111)에서 계면상태에 대한 분산 곡선을 Green's function을 통한 local density of state로부터 결정하였다.

목적: 저자들은 수술적 치료를 한 전이성 골종양 환자의 후향적 연구를 통하여 예후에 영향을 미치는 인자들을 조사하여 병적 골절이나 경막 외 침범들이 있는 환자와 같이 수술적 적응이 필요한 환자들을 선택할 수 있는 기준에 도움을 줄 수 있는 예후인자들을 찾아보고자 하였다. 대상 및 방법: 1985년 1월부터 2003년 12월 사이에 걸쳐 수술적 치료를 받은 78예의 전이성 골종양 환자에 대해서 생존에 영향을 미치는 중요한 예후 인자를 찾기 위해 Cox 비례위험모형과 Kaplan-Meier 생존곡선을 사용하여 분석 하였다. 결과: 생존에 의미 있는 4가지 예후 인자로는 원발암의 종류, 내장기 또는 뇌로의 전이 유무, 다발성 전이 유무, 이전 항암치료의 유무이었다. 4가지 예후 인자 중 2가지 이상을 만족시킬 경우를 좋은 예후군으로 분류하고 그렇지 못한 경우를 나뿐 예후군으로 분류하였다. 좋은 예후군의 6개월 평균 생존율은 95%, 1년 생존율은 87%이었고 나쁜 예후군의 6개월 평균 생존율은 28%, 1년 평균 생존율은 13%였다. 결론: 골 전이 환자의 수술적 치료의 결정에 있어서 생존 가능기간이 짧은 환자에게는 보다 덜 침습적인 치료가 필요하며 생존 기간이 길 것으로 예상되는 환자에게는 적극적인 수술이 필요하다. 사지의 골 전이에서는 생존 가능 예상 기간이 최소한 2개월 이상, 척추의 전이의 경우는 3내지 6개월이라면 적극적인 수술이 필요하다. 따라서 골 전이 환자의 치료의 결정에 있어서 본 연구의 예후 예측인자를 고려하면 더욱 유용한 수술적 치료의 선택을 할 수 있으리라 생각된다. Purpose: In this retrospective study, we tried to find out potential prognostic factors that can be used to determine the optimal treatment for some conditions that are indicated for surgery like pathological fractures or epidural compression. Materials and Methods: Between 1985 and 2003 we treated 78 patients with skeletal metastases. A multivariable analysis was conducted using the Cox proportional hazard model. The rates of survival were calculated by the Kaplan-Meier method. Results: We identified four significant prognostic factors for survival: the site of the primary lesion, the presence of visceral or cerebral metastases, any previous chemotherapy and multiple skeletal metastases. With these factors, we could divide the patients into two prognostic groups: the good prognostic group satisfies more than two of the four significant factors and the poor prognostic group doesn't. For the good prognostic group, the average rates of survival at 6 months and a year were 95% and 28%, respectively, and those for the poor prognostic group were 28% (6 mo) and 13% (1 yr), respectively. Conclusion: Each patient's life expectancy should be considered when we decide the surgical method for treating metastatic bone tumor. Patients with a very short life expectancy should probably be treated with a less invasive method but patients with a long life expectancy require aggressive surgery. If the life expectancy is estimated to be at least more than 2 month and 3-6 months for bony metastases to the extremity and spine respectively, then an aggressive surgical method should be chosen. With these practical prognostic factors, the life expectancy may be predicted more accurately and so the optimal surgical treatment can be selected more appropriately.
