규산질 광물 중 화학성분 원소인 $SiO_2,\;Al_2O_3,\;MgO,\;Fe_2O_3,\;CaO$ 및 $TiO_2$를 매트릭스 보정법을 이용한 X-선 형광분광법으로 분석하였다. 순수한 금속산화물을 혼합하여 만든 합성표준시료와 분석시료를 $Li_2B_4O_7$로 16배 희석, 용융하여 glass bead로 만들고 Lucas-Tooth와 Pyne 보정식을 사용한 실험계수법으로 성분간의 매트릭스 효과를 보정하였다. 각각 다른 세트의 매트릭스 계수를 사용하여 분석한 결과를 비교적 잘 일치하였으며 표준시료의 수가 많은 세트를 사용할 때 좋은 분석결과를 얻었다. 또한 NIST의 표준시료를 사용하여 이 방법에 의한 정확도를 검토하였다. The chemical ingredients such as $SiO_2,\;Al_2O_3,\;MgO,\;Fe_2O_3,\;CaO$ and $TiO_2$in silica minerals were determined by X-ray fluorescence spectrometry using a matrix correction method. The synthesized standards mixed with reagent grade oxides and the sample were diluted by fusing with 16 times $Li_2B_4O_7$. The matrix effects correlated among the ingredients were corrected by the empirical coefficient method based on the Lucas-Tooth and Pyne model. The analytical results showed relatively good agreement between the different sets of coefficients but were improved with increasing the number of standard. The accuracy of this method was also examined with the standard reference material of NIST.

직독식 원자방출분광기로 철강 재료중의 구성원소를 매트릭스 보정법으로 신속히 분석하는 방법에 대하여 연구하였다. 선형과 비선형법으로 매트릭스 보정계수를 구하였으며 이때 구한 매트릭스 계수는 서로 차이가 있지만 이들의 계수를 이용하여 구한 분석결과는 비교적 잘 일치하였다. A method to determine the iron and steels employing a Direct Reading Atomic Emission Spectrometer was investigated. Matrix effect was removed by two correction methods which utilize linear and curvilinear functions. Although two methods gave different sets of matrix correction coefficients, the analytical results by the two methods gave the same results. The analytical results obtained by the present work were well agreed with those obtained by inductively coupled plasma spectrometry.

This study has reviewed records of Taekkyeon maintained by foreigners in the late Joseon period and has made the following conclusion. As you can see from the book Gyobon Yeokdae Sijo Jeonseo written in 1648 (the 26th reign of King Injo), a Korean-French Dictionary and Games of the Orient, Taekkyeon was a child’s play. But in a Korean-English Dictionary edited by James S. Gale, Taekkyeon wasn’t described as a playgame. In the Joseon period. games, labor, and martial arts played and done by children and adults overlapped each other: labor and martial arts done by adults were often considered as games to children. For ordinary people, quarrels often ended up with no more than grappling, like holding each other’s topknots, and even a serious brawl ended when someone got a nosebleed and a bloodstain is left on white clothes. But to professional martial artists, martial arts were bloody fights for stakes. Records about such fights were maintained by the foreigners who visited Joseon or had interest in Joseon, an unknown world full of curiosity, and passed down to us. This author regards the fights mentioned above as Taekkyeon because most of the foreigners who kept the records stayed in Seoul and the martial arts played by children were basically the same as the martial arts performed by adults. Martial arts performed by professionals were joint events between villages on Jeongwol Daeboreum, the day of the first full moon of the lunar year, or so and often were skirmishes before Seokjeon, a mock fight with stone missiles. A friendly Taekkyeon match between villages didn’t allow lethal attacks using hands or knees. But unlike today’s Gyeollyeon Taekkyeon which restricts using hands or knees in a match, such lethal attacks weren’t prohibited in a skirmish match before Seokjeon and therefore the match would surely be bloody.

The main purpose of the study is to contribute to complementing two Korean traditional martial arts Taekwondo and Taekkyon and establishing firm identities of the two sports by comparing and analyzing their own techniques and rules of competition. The study found some similarities and uniqueness of them and findings are below. First, Sport Taekwondo and Taekkyon share similarities in kicking techniques. Second, Taekkyon, which practiced the time when no protective equipment was worn, applies Nuejin Balgil (slow kickng technique) to indirectly hit and to give less harm. When it is attacked, it does not defend but attacks the opponents in response of it, but it also considers the opponents’ safety. On the other hand, straight kick is a key technique of moden Taekwondo with protective equipment as it directly hit and strike the body. Taekkyon features no defense and active attack. Third, Taekkyon takes Pumbalgi(graceful steps) technique to load weight of the body on a leg before kicking or to practice more efficient kicking while Taekwondo uses Nongbobeop. Fourth, ‘Gguena Chagi(Multiple kicks)’ technique of modern Taekwondo is similar to ‘Straight kick’ of Taekkyon. Fifth, basically the two martial arts apply similar principles. For example, it players of Taekwondo do not wear protective equipment, the rules of competition and movement principles would adopt those of Taekkyon and vice versa.
