The aim of this study is to examine who had participated as members of the editorial staffs and their role in the Independent. In spite of the historical significance of the Independent, this topic was not treated properly by related studies. Moreover many studies mainly based on the Philip Jaisohn's autobiography showed the tendency to overemphasize his role. This study tried to overcome the limitations of the existing studies by critical reinterpretation of the historical materials and some new documents. The result of this study shows that 9 persons participated in the Independent. They are Philip Jaisohn, Joo Si-kyung, Yoon Chi-ho, Homer B. Hulbert, Son Seung-yong, Lee Jun-il, Henry Gerhart Appenzeller, H. Emberley and George Cobb. Five person including Jaisohn were Koreans and the rest were foreigners. Hulbert took part in editing English edition confidentially during some month from the beginning. Son Seung-yong seems to be the only one man to participate from beginning to end. Lee Jun-il was not a editorial staff but a treasurer, and Cobb participated temporarily in proofreading. Hulbert and Cobb were not official staff.

Background: Arirang is a UNESCO Intangible Cultural Heritage and intangible cultural property No. 129. However, research on the origin of Arirang in Seoul is still narrowly conducted, and it is necessary to investigate it academically. Purpose: This study is to clarify the research on the origin of traditional Arirang in Seoul area on a theoretical basis. Methods: I searched various documents to find the source of Arirang in Seoul. Results: The record of 'Arirang' was first confirmed as 'Arirang Taryeong(song)' in 'Hanyang-ga' in Maecheonyarok (Maecheon's history) by Hwang (1894). After that, Hulbert (1896) published the first modern sheet music and lyrics of <A-ra-rung> on music paper. In addition, Lee Sang Jun (1914) edited <Old Korean Folk Songbook, First volume> and recorded the lyrics and score titled 'Arirang Taryeong' on page 25 and the long Arirang Taryeong. Conclusions: Literally, the origin of 'Arirang in Seoul' is 'Arirang Taryeong' first recorded in 'Hanyang-ga' of Maecheonyarok. Arirang song, which originated in Hanyang, can be called Seoul Arirang. It is suggested that Seoul Arirang has a very high value as a protected cultural heritage of Seoul because of its historical and cultural characteristics.

A new predictor-corrector explicit time integration algorithm is presented for solving structural dynamics problems. The basis of the algorithm is the implicit generalized-.alpha. method recently developed by the authors. Like its implicit parent, the explicit generalized-$\alpha$ method is a one- parameter family of algorithms in which the parameter defines the high-frequency numerical dissipation. The algorithm can be utilized effectively for linear and nonlinear structural dynamics calculations is which numerical dissipation is needed to reduce spurious oscillations inherent in non-dissipative time integration methods used to solve wave propagation problems.

Since western mathematics and astronomy had been introduced in Chosun dynasty in the 17th century, most of Chosun mathematicians studied Shu li jing yun(數理精蘊) for the western mathematics. In the last two decades of the 19th century, Chosun scholars have studied them which were introduced by Japanese text books and western missionaries. The former dealt mostly with elementary arithmetic and the latter established schools and taught mathematics. Lee Sang Seol(1870~1917) is well known in Korea as a Confucian scholar, government official, educator and foremost Korean independence movement activist in the 20th century. He was very eager to acquire western civilizations and studied them with the minister H. B. Hulbert(1863~1949). He wrote a mathematics book Su Ri(數理, 1898-1899) which has two parts. The first one deals with the linear part(線部) and geometry in Shu li jing yun and the second part with algebra. Using Su Ri, we investigate the process of transmission of western mathematics into Chosun in the century and show that Lee Sang Seol built a firm foundation for the study of algebra in Chosun.

Humic substances include several biological active and inactive compounds that are commonly used for improving soil fertility. Use of humic substances in swine diets is a novel concept. Humic substances contain 8,700 mg/kg of iron but its bioavailability is unknown. This study was conducted to test the bioavailability of iron in humic substances for nursery pigs. One hundred twenty five pigs (Newsham, Colorado Springs, CO) were not given supplemental iron while nursing for 21 d. Pigs were weaned on d 21 and allotted to one of five treatments (four control treatments with different levels of supplemented iron; 0, 30, 70 and 88 mg/kg from ${FeSO}_4$ and one treatment with 70 mg/kg iron from humic substances). Pigs were fed diets for 5 wk ad libitum and water was accessible freely. Body weight and feed intake were measured weekly. Blood samples were taken from pigs on d 28 to measure the number of red blood cells and hemoglobin concentration. Pigs fed a diet with the humic substances grew faster (p<0.05) during the first week postweaning, but performance was not different during the entire 5 wk period. Feed intake and gain/feed were the same among treatments. The slope ratio technique was used to estimate relative iron bioavailability. The concentration of blood hemoglobin did not respond to dietary iron levels using this model. However, the number of red blood cells (106/$\mu$l) was modeled by 4.438+0.017${\times}$ 'ron (mg/kg) from ${FeSO}_4$'0.012${\times}$'ron (mg/kg) from the humic substances' Based on the comparison between the slopes (0.012 from humic substances and 0.017 from ${FeSO}_4$), iron in humic substances was 71% as available as the iron in ${FeSO}_4$. The slopes for dietary feed intake of ${FeSO}_4$ and the iron in humic substances did not differ (p>0.05). Humic substances can replace ${FeSO}_4$ as an alternative iron source for pigs at 71% relative bioavailability.
