Seoul Shinmun
''Seoul Shinmun'' () is a Korean-language daily newspaper published in South Korea. The newspaper claims descendency from a newspaper established by Englishman Ernest Bethell in Korea on 29 June 1904 called '' The Korea Daily News'' (''Taehan maeil sinbo''); per this claim, ''Seoul Shinmun'' would be the oldest active newspaper in South Korea. It published in both English and Korean, and soon became significantly influential due to its ability to publish critically about the Japanese government, which was rapidly encroaching on Korean sovereignty at the time. However, mounting pressure caused it to be sold in 1910. It renamed to ''Maeil sinbo'', and largely published along Japanese colonial government lines.

Scientist Of The Year Award
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Performance-enhancing Drugs
Performance-enhancing substances (PESs), also known as performance-enhancing drugs (PEDs), are substances that are used to improve any form of activity performance in humans. Many substances, such as anabolic steroids, can be used to improve athletic performance and build muscle, which in most cases is considered cheating by organized athletic organizations. This usage is often referred to as doping. Athletic performance-enhancing substances are sometimes referred to as ergogenic aids. Cognitive performance-enhancing drugs, commonly called nootropics, are sometimes used by students to improve academic performance. Performance-enhancing substances are also used by military personnel to enhance combat performance.

Blind Experiment
In a blind or blinded experiment, information which may influence the participants of the experiment is withheld until after the experiment is complete. Good blinding can reduce or eliminate experimental biases that arise from a participants' expectations, observer's effect on the participants, observer bias, confirmation bias, and other sources. A blind can be imposed on any participant of an experiment, including subjects, researchers, technicians, data analysts, and evaluators. In some cases, while blinding would be useful, it is impossible or unethical. For example, it is not possible to blind a patient to their treatment in a physical therapy intervention. A good clinical protocol ensures that blinding is as effective as possible within ethical and practical constraints. During the course of an experiment, a participant becomes unblinded if they deduce or otherwise obtain information that has been masked to them. For example, a patient who experiences a side effect may co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
