Ⅰ. A preface
1. Adolescence vs. Puberty
Adolescence is the transitional period between childhood and adulthood during which young people mature physically and sexually. Adolescence should be differentiated from puberty, which is more specific. Adolescence might be considered a cultural concept that refers to a general time during life.
In the other hand, puberty is a physical concept t
preservation technologies. Various modern technologies are applied to inhibit the growth of micro-organisms in food product as various food-spoilage micro-organisms are exit. Consequently, the techniques are so complicated and diverse to state in one paragraph. This report divides the methods into several categories, physical, biological, and chemical, and introduces each technology briefly.
1. Introduction of this study
Recently, One of U.S organizations sent back 30,000 applicants who are not just normal students, but highly-qualified students like someone from Harvard, Yale, and so on. This organization is neither Harvard Law School nor the famous investment company, Goldman Sachs. This is ‘Teach for America’, a non-profit organization for the equality in education. It is als
Theory
In general, preparation methods for nanoparticles make use of capping agents, such as surfactants, polymers or biomaterial, in order to confine the growth. Occasionally, the selective or preferential adsorption of capping agents onto particular crystallograp- hic facets during the growth stage permits diverse shapes to be produced, for example triangles, hexagons, disks, rods and multi

다. Amino Acid의 Titration과 pH buffer 작용
Amino Acid를 NaOH와 같은 염기로 Titration을 하여 얻어지는 Titration Curve는 적정하는 Amino Acid의 pH buffer 작용을 잘 설명해 준다.
즉 Amino Acid의 Carboxyl기는 Weak Acid이므로 NaOH-와 같은 Strong Base와 반응하면 일정한 pH 범위 내에서 큰 pH 변화를 일으키지 않는 pH Buffer 작용을 한
physical exercise, and sleep –- which may seem too obvious and so easily overlooked in their impact on education. By conditioning our minds and bodies correctly, it is possible to take advantage of the brain’'s potential for plasticity and to facilitate the learning process. This calls for holistic approaches which recognize the close interdependence of physical and intellectual well-bein
