popular hypothesis for depression involving decrements in neurotrophic factors – neurodevelopmentally expressed growth factors that also regulate plasticity within adult brain. From a serial of depression patients’ decreased volume of hippocampus and other prefrontal region was observed. This supports popular hypothesis including decrease of neurotrophic factors. Neurotrophic factors are
Herbert Spencer coined the phrase "survival of the fittest” in his 1851 work Social Statics and later used it to characterize what Charles Darwin had called natural selection.
J.B.S. Haldane was the first to quantify fitness, in terms of the modern evolutionary synthesis of Darwinism and Mendelian genetics starting with his 1924 paper A Mathematical Theory of Natural and Artificial Selection

<요약> 생물에는 환경에 대한 적응력이 있어, 자주 사용하는 기관은 발달하고 사용하지 않 는 기관은 퇴화하여 없어지게 된다는 학설로 J.라마르크가 제창한 진화설이다.
J. 라마르크는 1809년 《동물철학》이라는 저서에서 생물학사상 처음으로 생물 진화에 대한 이론을
3. Types of Learning disability
1) Academic Learning disability
These Disabilities are also respectively termed "dyslexia"(Reading Disorder), "dysgraphia"(Writing Disorder), and "dyscalculia"(Mathematics disorder). Youth with learning disabilities most are reading disabled.

넓은 의미로는 생물의 진화에 관해 연구하는 학문분야를 말하는데, 여기서는 진화론의 역사를 개관하기로 한다. 고대 그리스의 자연철학자들 중에는 사물의 생성(生成)문제를 논한 사람이 많았다. 그 중 한 사람인 엠페도클레스는 지(地) ·수(水) ·풍(風) ·화(火) 4원소의 결합 분리로 경험세계의 생멸
응고장애는 선천적인자 혹은 후전적인자에 의해서 발생한다. 선천적인자에 의한 응고장애의 발생빈도는 낮은 편이나, 최근의 연구보고에 의하면 새로운 선천적인자가 발견되고 있으며, 이 인자로 인한 응고장애가 이전의 발병율보다 높게 나타나고 있다. 선천적 응고장애는 antithrombin III (ATIII)와 , p
