Until the late 19th century, $\ulcorner$Gagogwonryu(歌曲源流)$\lrcorner$ was a collection of songs which had powerful influence on Gagog tradition. However, its role on Gagog(歌曲) tradition since then is less well known. Generally, it is presumed that Gagog tradition might disappeared by giving way to modern song genre. So this article question that $\ulcorner$Gagogwonryu$\lrcorner$ became extinct rapidly between the late 19th century and early 20th century, and follow $\ulcorner$Gagogwonryu$\lrcorner$ tradition of early 20th century. Gagog instruction for beginner had a clue to answer this question. This instruction was written by Ha Son-il(河順一) who was a teacher and singer in a private music institute. named 'ChoyangGurakbu(調陽俱樂部). Accordingly, this article has processed two phases in order to find out this question. First of all, this article analyzed Gagog instruction that Ha soon-il edited. As a result, it found out that Gagog instruction included the whole $\ulcorner$Gagogwonryu$\lrcorner$'s contents in the 19th century and was transmitted actively until the early 20th century. Second, this article found out $\ulcorner$Gagogwonryu$\lrcorner$ tradition of the early 20th century by analyzing character of ChoyangGurakbu. And also this article discovered ChoyangGurakbu had been managed by an vigorous aid association. Gagog instruction for beginner written by Ha Son-il had spreaded from strength to strength in the early 20th century.

1. 고추 무농약재배 비가림 시설재배 효과 무농약 고추 노지 터널재배와 비가림 재배의 수량성을 검토하고, 관행 비가림 시설에 측고와 동고를 높이고 가로대를 보강하여 최소한의 투입으로 작물재배 환경을 개선으로 농작업에 편리성을 도모하고자 시험을 수행한 결과 비가림 시설재배가 노지 터널재배에 비하여 생육이 양호하고. 수량이 2배정도 많았다. 노지재배 고추는 강우로 인하여 탄저병이 40% 정도 발생되었으나, 비가림 시설재배는 탄저병과 역병이 전혀 발생되지 않았다. 2. 고추 비가림 시설 환경 개선 효과 구명 비가림 시설의 측과와 동고를 높이는 간단한 환경개선으로 여름철은 시설내 온도가 관행 비가림 시설보다 낮아지는 효과가 있었다. 또한 비가림 시설환경 개선에 의해서 "녹광" 풋고추의 생육은 증가되었으며, 홍고추 "조양" 품종도 같은 경향이었다. 고추의 수량은 풋고추 "녹광" 품종이 홍고추 "조양" 품종보다 수확량이 현저하게 많았고 처리간에는 비가림 시설의 환경을 개선한 시설이 관행 비가림 시설에 비하여 증수되었다. 그리고 비닐온실의 측고를 높인 결과 비닐 온실 내 측면으로 사람의 통행이 자유로워 작업환경 도도 개선되었다.

A new naked oat cultivar 'Choyang' (Avena sativa L.) was developed by the breeding team at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2007. It was derived from a cross between 'Sikyonggwiri' and 'Gwiri23'. The cultivar, Sikyonggwiri is early heading while the breeding line Gwiri23 has a high yielding potential with large-size grain. Bulk method combined with pedigree selection program was employed in subsequent generations, and the promising line SO96025-B-303-44-2-5 was selected for agronomic performance in 2002. The line showed both high yield and good husking rate of seed in the Yield Trial tested at Suwon in 2003 to 2004, and was subsequently designated as 'Gwiri57'. Gwiri57 was evaluated for winter hardiness, earliness, and yield in four locations, Gimje, Iksan, Jeongeup and Jinju from 2005 to 2007 and was released as Choyang. Choyang headed 11 days earlier and matured 5 days earlier than the check cultivar 'Sunyang' in the paddy field condition. The new cultivar Choyang had 97 cm of culm length and 23.4 cm of spike length, 658 spikes per $m^2$, 75 grains per spike, 28.8 g of 1,000-grain weight, and 636 g of test weight. Choyang showed better winter hardiness than that of the check cultivar Sunyang, and similar seed quality to the check cultivar in respect to crude protein (12.9%) and ${\beta}$-glucan content (4.7%). However, it showed higher husking rate than the check cultivar. The grain yield of Choyang in the regional yield trial for 3 consecutive years was averaged $4.67MT\;ha^{-1}$, which was 38% higher than that of the check cultivar Sunyang. Choyang is recommended for the fall sowing cropping only in the southern area where daily minimum mean temperatures are averaged higher than $-4^{\circ}C$ in January, and is not recommended the in mountain area where frost damage is presumable.

장막내의 고립성 섬유성 종양은 드물며 대부분 장측 또는 벽측 흉막에서 발생하지만 종격동, 심막, 복막, 폐실질 , 안과 그리고 뇌척수막에서도 발생하기도 한다. 이 종양은 다양성으로 인하여 진단하는데 어려움이 있으며, 특히 종격동이나 흉부 외의 장소에서 발생하는 경우에는 더욱 그러하다. 이 종양의 임상적 양상을 예측하기 어려우며 조직학적으로 양성의 소견을 보이면서, 임상적으로는 악성의 양상을 띠기도 한다. 악성의 임상양상을 보이는 경우는 약 13∼23% 정도로 보고되고 있다. 저자는 53세의 여자 환자에서 종격동의 고립성 섬유성 조양을 수술한 후, 4차례 재발한 드문 증례를 수술 치험하였기에, 문헌 고찰과 함께 보고하는 바이다.

New compounds of melaminium 2,6,7-trioxa-1-phosphabicyclo[2.2.2]octane-4-methoxy-sulfate have been synthesized and characterized by means of chemical analysis, 1H, 13C, and 31P NMR, and IR spectroscopies. When the compounds are subjected to an open flame, they foam without melting to produce a light char with about 50 times volume of the initial compounds. The evaluation of these flame-retardants proves to be efficient for polypropylene. Thermogravimetric analysis discloses that the compounds are also thermally stable for compounding into polypropylene without decomposition.
