  • 성공적인 종이수술을 위하여 안전하고 효과적인 접착제가 필요하며, 합성 접착제의 독성작용 때문에 인체에서 추출한 접착제를 사용하게 되었다. Fibrin 접착제가 저장 혈액에서 체취되면 감염성 질환의 전염 위험성이 있지만 자가 fibrin 접착제를 사용하면 전염위험성이 없다. 저자들은 ammonium sulfate fibrin 접착제와 상품화된 fibrin 접착제의 접착력을 비교한 결과 ammonium sulfate fibrin 접착제의 접착력이 상품화된 fibrin 접착제의 반 정도의 접착력을 가지지만 그 정도의 접착력이면 고막재생술, 안면신경 봉합술, 이소골 재건술, 외이도 후벽재건술, 뼈가루를 이용한 전두동 및 유양동폐쇄술 등 이비인후과 수술에 사용하기엔 충분한 접착력이다.

  • This study was conducted to investigate the effects of slow-releasing fertilizer and sowing date on waxy corn propagated through double cropping without tillage. "Mibaek 2" was sown for first cropping on March 25th, April 5th, and April 15th, and for second cropping on July 5th, July 15th, and July 25th in 2018-2019. In order to save labor, slow-releasing fertilizer was utilized only one time before sowing. The accumulated temperature from sowing to silking was about 590-700℃. It took 65-77 days when "Mibaek 2" was sown in early April, but the one sown in early July took 42-52 days. In the first cropping, the culm length and ear length caused by the sowing date had no statistical significance, but the kernel set length was the highest at 123 cm in the sowing district on April 5th. The weight of marketable ears was the highest at 100%, in addition to soil testing-based recommended fertilization. Meanwhile, in the second cropping, culm length, ear length, and yield were less compared to the first cropping. The culm length, kernel set length, ear length, and seed set length decreased as sowing date was delayed. The number and yield of marketable ears were the highest at 100%, in addition to soil testing-based recommended fertilization like in the first cropping. It has been found that securing yield by July 15th to finish the second seeding of the crop in the central part of Korea is advantageous. These results of this study will be helpful to farmers for the double cropping of waxy corn cultivation and management.

  • The growth, yield and chemical properties of waxy corn $Sonjajang{\times}KNU-7$ and $Asan{\times}KNU-7$ planted in different dates and mulch types in a converted paddy field was investigated. Experiment was carried out in a randomized complete block design in a split split-plot arrangement with four replications. Planting dates (D) [May 16 (D1, early), June 1 (D2, middle), June 6 (D3, late)] represented main plots, plastic mulch (M) [(BM, black mulch; TM, transparent mulch)] for subplots while waxy corn crosses [$Sonjajang{\times}KNU-7$ (‘Sonja’) and $Asan{\times}KNU-7$ (‘Asan’)] for sub-subplots. Results showed that D had a significant effect on growth characters except emergence, ear quality except ear diameter, and yield whereas M showed significant effect on growth characters only. Superior growth and ear quality performance were recorded in D1 and BM. In terms of crosses, ‘Sonja’ had better growth performance than ‘Asan’ regardless of D and M, but performed better at D1 and BM. Highest yield was obtained in D1 for BM (2,131 kg $10a^{-1}$) and TM (1,655 kg $10a^{-1}$) but no significant difference in the yield across V was recorded. In terms of starch and sugar contents, a decreasing trend was observed from D1 to D3 regardless of M and V.

  • 단옥수수와 초당옥수수의 출사후 이삭의 성숙정도와 당함량, 이삭부위별 당도, 저장기간에 따른 당류의 변화등을 구명하기 위하여 작물시험장 전작시험포장에서 GCB 70과 NES를 1991년 3월 5일에 비닐하우스에서 파종육묘하여 4월 1일에 본포에 이식후 소형 비닐턴넬로 재배하였다. 출사후 15일부터 30일까지 5일 간격으로 4회 수확하여 생육특성 및 당함량을 조사하였으며 이삭의 부위별 당함양은 출사후 25일에 1회 조사하였다. 저장중의 당류조사 는 냉장고(4$^{\circ}C$)에 9일간 저장하였다가 2일간격으로 5회에 걸쳐 HPLC를 이용하여 총당함량중의 당류 변화를 분석한 결과를 요약하면 다음과 같다. 1. GCB 70과 NES 두 품종 모두 간장, 이삭무게, 100입중 등은 출사후 30일 까지 증가경향이었으나 출사후 25일과 30일 사이에는 증가폭이 좁았다. 2. 두품종 모두 출사후 15일에 당함량이 가장 높았으며 이삭의 발육정도는 출사후 30일가지 증가 경향이나 25일부터 당함량이 급격히 저하되므로 단 옥수수는 출사후 15~20일경, 초당옥수수는 출사후 20~25일경이 수확적기로 보였다. 3. 이삭부위별 당함량은 두 품종 모두 이삭하단>이삭중간>이삭상단 순위로 높았다. 4. 초당옥수수는 수확당시의 저장후 9일까지의 당도변화가 거의 없었으나 단옥수수는 저장 3일후 부터는 당도가 급격히 저하되었다. 5. 총당중에서 Sucrose, Glucose, Fructose 등은 단옥수수보다 초당옥수수보다 단옥수수가 높았다.

  • Clothing fitness is strongly required in the apparel industry, and draping is an effective tool to increase fitness to the wearers. A more sophisticated and systematic information of the somatotype, accordingly, is necessary for better cress form design. This study was performed to provide fundamental data on middle aged women's upper torso for dress form designers and pattern makers by classifying the somatotype based on each individual's lateral view, and analyzing the characteristics of their somatotype. Data were analyzed by factor analysis, cluster analysis, analysis of variance. Factor analysis was used to 23 items from photometric measurment and cluster analysis was applied for classification of upper torso forms. Through cluster analysis using 5 factor scores, 3 somatotypes were categorized from th lateral view 1) Type I was straight somatotype in which the plumb line passes throught the lobe of the ear, the shoulder joing and the mid abdominal region laterally. This type of woman was slender and shorter than average. 2) Type II was bending somatotype in which the upper portion of upper torso is bent forward. This type of woman was taller and fatter than average. 3) Type III was swayback somatotype in which the upper portion of protruding point on the back is bent forward but the lower portion of protruding point had characteristic of turning over somatotype. This type of woman had storter length on the front and longer lenght on the back, slender type and flat chest.

  • Traumatic arteriovenous fistulas (AVFs) involving the external carotid artery are exceedingly rare in young adults. Since an AVF is the most common life-threatening cause for pulsatile tinnitus (PT), meticulous evaluation and treatment of patients with PT is crucial. Here, we present two traumatic AVF cases treated with coil embolization leading to no residual fistulous connections followed by an immediate and complete resolution of PT. A 20-year-old man developed left ear tinnitus three months after a traumatic brain injury involving the right temporal bone fracture. Cerebral angiography demonstrated an enlarged left middle meningeal artery (MMA) and a fistular point at the posterior branch of the MMA draining to the middle meningeal vein (MMV) and the left pterygoid plexus, suggesting an AVF. Another 18-year-old girl developed left tinnitus, left exophthalmos, and conjunctival injection 6 months after a traffic accident involving no demonstrable abnormal findings in the radiologic exam. Magnetic resonance angiography demonstrated a markedly dilated left MMA draining to the MMV, left cavernous sinus, and left superior ophthalmic vein. In both cases, coil embolization was performed with total obliteration of the fistular point.

  • Dokdo, which is located in the middle of the East Sea, is a small island tilth a total area of 0.186 $\textrm{km}^2$. However, this small island, with its mild oceanic climate, has rich bio-resources and picturesque natural surroundings. Dokdo in the crystaline waters and In the central area of the deep sea is a treasury of algaes (sea oak, sea mustard, gulf weed, laver, agar-agar, etc.), molluscs (squid, ear shell, conch, etc.) and fishes (Alaska pollack, anchovy, saucy, herring, etc.). On the other hand, there are a lot of grasses and various kinds of grasses on the land of Dokdo. And a lot of back-tailed gulls (about 20,000 Individuals) live on this island. There have been disputes on the sovereignty over Dokdo between Korea and Japan. Japan has claimed sovereignty over Dokdo since Japan incorporated the island into Japanese territory in 1905 when it occupied the Korean Peninsula by force. Korea governed Dokdo not only before 1905 but also after its liberation in 1945. The Korean government, while heavily financing building facilities like pleas and quays, is endeavoring to preserve the natural surroundings of this island.
