The purpose of this study was to invesigate the effects of Seo Dong-Il's technique on voice quality in patients with vocal nodules and phonasthenia (vlcal fatigue). The patients (4 nodules and 6 vocal fatigue) participated in teh study. Each subject was assessed acoustically (Fo, Jitter, Shimmer, NNE) in the first and last session. Dr. Speech (version 3.4, Tiger-DRS) was used to compae acoustic parameters of pre- and post-treatment. Seo Dong-Il's technique consisted of breating exercise, relaxation exercise, and phona-tion exercise The results were as follows: First, Seo Dong-Il's technique tended to be effective on improving voice quality in patients with phonasthenia and vocal nodules. Secon, the nature of improvements wee as follows: there was a significant difference between pre- and post-treatment in shimmer (p < .01) and NNE (p < .001), while there was no significant difference between pre- and post-treatment in Fo and Jitter. Finally, given the fact that the number of subjects was only 10, the jitter might have shown a significant difference if more subjects partcipated in teh experiment.

콩나물로부터 고 isoflavone 함량의 콩 식품윈료를 얻고자 콩나물 재배 시 빛을 쪼여주고, 재배한 콩나물의 저장온도를 달리한 조건에서 isoflavone 함량변이 를 조사하였다. 공시 품종들의 7일 재배 후 저장하기 전 isoflavone함량은 아가 3호>아가 1호>아가 2호>아가 4호>장기콩>보석콩>은하콩>풍산나물콩 순이었는데 아가 3호의 isoflavone 함량은 4,619㎍/g이었다. 재배한 콩나물의 isoflavone 함량은 저장온도에 따라 품증별로 상이한 차이를 보였는데, 저장온도 6℃와 20℃에서 isoflavone함량이 높은 반면 저장온도 9℃와 30℃에서는 대부분 콩 품종들의 isoflavone 함량은 낮았다. 저장일수에 따른 isoflavone의 함량은 품종들 간에 일정한 경향이 없었으나 대부분의 품종들은 저장기간 3일 이내에 가장 높은 isoflavone 함량을 보였고, 아가 4호와 장기콩은 저장기간 5일에서도 높은 isoflavone의 함량을 보였다. 저장기간과 온도처리를 하여 재배한 콩나물의 isoflavone 함량을 높이고자 한 결과 아가 3호를 포함하여 공시한 8품종 중 4품종에서 20'C에서 하루 동안 저장했을 때 가장 높은 isoflavone의 함량을 나타내었다. 재배한 콩나물들 중 저장을 통해 가장 높은isoflavone의 함량을 보인 품종은 아가 3호로써 저장후의 isoflavone 함량은 11,705㎍/g이었다. 본 연구에서는 콩나물 저장기간 동안 수분공급이 지속적으로 이루어겼기 때문에 콩나물이 계속 성장한 것으로 생각된다. 따라서 저장기간 동안 온도처리를 달리하여 isoflavone의 함량을 증가시키는 보다 확실한 방법을 확립하기 위해서는 더 많은 연구가 이루어져야 할 것으로 생각되어진다. To obtain food materials of high isoflavone content from soy-sprouts, 8 soy-sprout varieties, Aga 1, Aga 2, Aga 3, Aga 4, Pungsannamulkong, Eunhakong, Jangkikong and Bosugkong, were grown into soy-sprouts for 7 days under light condition and stored for 5 days at 6 different temperatures; 3, 6, 9, 20, 30, and 40℃ in the dark. The isoflavone content of 7 days grown sprout varieties were highest in the order of Aga3>Aga 1>Aga 2>Aga 4>Jangkikong>Bosugkong>Eunhakong>Pungsannamulkong. The highest isoflavone content of Aga 3 was 4,619 ㎍/g. The isoflavone content of soy-sprouts showed much varietal differences depending on the storage temperatures. Comparative high isoflavone content was obtained at storage temperatures of 6℃ and 20℃ while most of varieties showed low isoflavone content at 9℃ and 30℃. No constant trend in isoflavone content for the tested varieties along with the days to storage but most of varieties showed the highest isoflavone content in 3 days of storage. On the contrary, Aga 4 and Jangkikong showed high isoflavone content even at 5 days of storage . The comparatively high isoflavone content for 4 varieties including of Aga 3 out of 8 varieties was obtained from the treatment of one day storage at 20℃. Out of all treatments, the highest isoflavone content was obtained from one day storage at 20℃ for Aga 3 and the content was as high as 11,705 f-㎍/g. In this experiment, soy-sprouts were believed to be made continuous growth during the storage because the sprouts were being dipped in water during the temperature treatment to protect soy-sprouts from drying. Thus, it is inferred that additional researches should be made to establish better method to increase isoflavone content in soy-sprouts during the storage.

숙취해독에 탁월한 효과를 지니는 asparagine 함량의 콩나물 계통간 차이와 뿌리 발생량에 따른 차이 및 콩나물 재배기간에 따른 차이를 구명하여 고 asparagine을 가지는 기능성 콩나물 생산과 품종육성을 위하여 국내재래 콩나물 계통의 asparagine함량을 분석한 결과를 요약하면 다음과 같다. 1. 공시된 나물콩 174품종 및 계통의 콩나물에서의 sparagine 함량의 범위 및 평균은 0.38-1.67%, 0.99%(생체수준)로 각각 나타나 다양한 변이를 보였다. 2. 공시된 장려품종과 재래계통의 asparagine함량은 각각 1.29, 0.96% (생체수준)로 재래계통보다 장려 품종에서 높게 나타났다. 3. 백립중별 asparagine함량은 8.1~10.0g범위에서 1.02%(생체수준)로 가장 높은 경향이었으나 유의적인 차이는 인정되지 않았다. 4. 종피색별 asparagine 함량은 갈색종피종이 1.15%(생제수준)로 가장 높았으며 다른 종피종들은 비슷한 경향으로 나타났다. 5. 공시된 장려품종의 asparagine 함량의 범위는 4.08~6.24%(건물수준)로 나타났고, 다원콩(6.24%), 소백나물콩(6.21%), 소원콩(5.95%), 소명콩(5.85%) 순이 었다. 6. 콩나물의 재배일수를 10일로 한 경우 asparagine함량과 관계가 깊은 뿌리발생량이 크게 증가하였다. 7. 재배일수에 따른 asparagine함량은 5일재배와 10일재배에서 각각 0,68%, 1.21%(생제수준)로 나타나 재배 일수간 asparagine 함량에는 고도의 유의적인 차이가 인정되었다. 8. 콩나물의 하배측 부위에서 재배일수가 증가할수록 asparagine 함량도 증가하여 2일 재배시 2.91%(건물수준)이던 것이 14일 재배시에는 15.68%까지 증가하였다. The varietel difference, effect of root amounts and cultivation duration on the asparagine content of soybean sprouts, which is known to have the excellent detoxifying effect of ethanol, were investigated for developed varieties and indigenous sprout lines to establish cultivation methods of increasing the asparagine content and to develop soybean varieties having high asparagine content. Some of the research results obtained are summarized as follows; 1. Range and mean of asparagine content of 174 germplasm were 0.38~1.67% and 0.99%, respectively, on fresh weight basis. 2. Developed sprout-soybean varieties showed somewhat higher asparagine content of 1.29% than that of indigenous sprout lines of 0.96% on fresh weight basis. 3. No significant difference in asparagine content among the seed size groups was recognized though the highest asparagine content, 1.02% on fresh weight basis was observed in the seed size of 8.1~10.0g/100 seeds. 4. Among the seed coat color groups, soybean of brown seed coat color showed the highest asparagine content (1.15%) on fresh weight basis. No difference was observed among other groups of seed coat color. 5. Range of asparagine content of 174 varieties was 4.08~6.24% on dry weight basis. Soybean varieties that showed high asparagine content were Dawonkong, Sobacknamulkong, Sowonkong, and Somyungkong, with the contents of 6.24%, 6.21%, 5.95%, and 5.85%, respectively. 6. Amount of roots which have the highest asparagine content out of sprout parts was greatly increased up to 10 days of sprout cultivation. 7. Highly significant difference in asparagne content of sprout was recognized between those grown for five and ten days, with the asparagine content of 0.68% and 1.21%, respectively, on fresh weight basis. 8. Asparagine content of hypocotyle part was also highly proportional to days to cultivation; it increased from 2.91% at 2 days of cultivation to 15.68% on fresh weight basis at 14 days of cultivation.

정연신,손태호,Krishna Hari Dhakal,이정동,황영현 경북대학교 농업과학기술연구소 2008 慶北大農學誌 Vol.26 No.-

알코올의 숙취해독에 뛰어난 효과가 있는 것으로 알려진 sparagine은 콩나물의 뿌리에 함량이 가장 많은 것으로 알려져 있다. 본 연구논문에서는 콩나물 뿌리 발생에 미치는 재배실의 온도, 일당 관수횟수, 재배일수 및 동일용기에 사용한 콩 량에 대한 영향을 조사하여 얻어진 연구결과를 요약하면 다음과 같다. 1. 아가통과 풍산나물콩의 수율은 재배일수에 따라 경시적으로 증가하였으며, 재배실 온도가 20℃에서 보다 30℃에서 높았으며, 콩나물의 수율은 5회 관수, 8일 재배시 가장 높았다. 2. 아가콩과 풍산나물콩의 콩나물 부위별 건물중의 비율은 자엽이 가장 많았고 뿌리가 가장 낮았으며, 재배실 온도가 20℃에서 보다 30℃에서 비율이 더 높았다. 3. 아가콩의 sparagine 함량은 재배실 온도 30℃에서 5회 관수 8일 재배한 하배축에서 18.9%로 가장 높게 나타났다. 4. 풍산나물콩의 sparagine 함량은 재배일수가 길수록, 재배온도가 높은 경우 높았으며, 하배축에서 가장 높았고, 30℃에서 2회 관수 8일 재배시 하배축에서 18.8%로 가장 높게 나타났다. 5. 아가콩은 300g, 풍산나물콩은 500g 치상시 수율이 가장 높았으며, 잔뿌리의 수는 아가콩과 풍산나물콩 모두 치상량이 증가함에 따라 증가하는 경향이었다. It is known that the content of asparagine, an excellent detoxifying substance of alcohols in human body, is the highest in the roots of soy-sprout. At the same time, it is inferred that soy-sprouts producing more roots are better for detoxifying. In this experiment, the effects of room temperatures on number of watering per day, and duration of soy-sprout culture were carefully investigated. Some of the results obtained are as follows; 1. The yield rate of soy-sprouts for Agakong and Pungsannamulkong was continuously increased up to 9 days. It was higher in room temperature of 30℃ than in 20℃ and was the highest at 8th day of culture with 5 times of watering per day. 2. The asparagine content in soy-sprouts of Agakong and Pungsannamulkong was the highest in cotyledon and the lowest in roots. This rate was higher in the room temperature of 20℃ than in 30℃. 3. The highest asparagine content of soy-sprout of Agakong was 18.9%, obtained in the room temperature of 30℃, cultivated for 8 days with 5 times of watering per day. 4. The highest asparagine content of Pungsannamulkong was 18.8%, obtained in hypocotyl cultivated in the room temperature of 30℃ for 8 days with the number of 2 times watering per day. 5. When an cultivation apparatus of 5 liters volume was used, the optimum seed amount for the highest yield rate was 300g for Agakong and 500g for Pungsannamulkong. At the same time, the number of lateral roots showed increasing tendency with more amounts of soybean seeds used.

고추 역병 저항성 재료의 특성평가와 종자 증식

김동우,김병수,배수연,한정혜 慶北大學校農業科學技術硏究所 2002 慶北大農學誌 Vol.20 No.-

역병 저항성 재료로 도입하여 유지하고 있는 PI123469, PI201234, PI201232, AC2258 (=Line 29), CM334, KC268, KC358, KC820, KC821, KC822, KC823 (Line 29 = AC2258), KC462, KC463, KC464 혹은 이들 유전자원에서 선발한 계통들의 역병에 대한 저항성 검정, 원예적 특성 조사 및 종자 증식을 실시하였다. PI123469, PI201234, PI201232, AC2258, KC823 에서 선발된 계통들이 가장 저항성이 강한 것으로 나타났다. 동일한 유전자원에서 선발한 계통간에도 저항성 수준에서 현저한 차이가 관찰되는 경우가 있었으며, 이러한 경우는 주로 유지 증식과정에 자연교잡이 일어난 결과로 추정되었다. 따라서 순도 높은 저항성 재료를 얻기 위해서는 봉지를 씌워 자식종자를 채종하는 것이 가장 안전하며, 다음으로는 계통 망실 혹은 망상을 이용하는 것이 바람직한 것으로 판단되었다. Resistance to Phytophthora capsici and horticultural characteristics of selections from the resistance sources such as PI123469, PI201234, PI201232, AC2258 (=Line 29), CM334, KC268, KC358, KC820, KC821, KC822, KC823 (Line 29), KC462, KC463, KC464 were evaluated and recorded in the process of seed increase. Selections of PI123469, PI201234, PI201232, AC2258, KC823 (Line 29 = AC2258) of them showed the highest level of resistance. A considerable difference in the level of resistance was observed between lines selected from the same sources. The variation between selections derived from the same source was thought to ve attributable to natural cross-pollination that may have occurred during the seed increase. Therefore, securing self-pollinated seed by wrapping the flower buds before anthesis would be necessary to obtain genetivally pure resistant lines. The next alternative would be to increase the seed in small net houses for single line or field cage.

2000년도에 검정에서 역병에 살아남은 개체들로부터 채종하여 육성한 Capsicum chinense 31계통에 대하여 역병 저항성을 검정한 결과 고도의 저항성을 나타내는 것은 발견되지 않았다. 2001년도의 검정에서 역병에 살아남은 개체로부터 채종한 재래종 26계통에 대하여 다시 역병 저항성 검정을 실시한 결과 KC180, KC230, KC195, KC194에서 다수의 개체가 살아남아 저항성을 나타내었다. 그러나 KC180과 KC230은 각각 AC2258과 CM334와 혼종된 것으로 관찰되었다. KC195와 KC194는 재래종의 형질을 유지하고 있는 것으로 관찰되었다. CM334의 보존 증식과정에 자연교잡이 일어난 것으로 보여 이의 순도향상을 위하여 채종년도별로 시료를 꺼내어 역병저항성 검정을 실시한 결과 가장 오래된 1992년도 채종종자에서부터 약간의 이형주가 관찰도기 시작하여 1995년부터 2001년도까지 시간이 경과함에 따라 많이 변형되어 있는 것을 알 수 있었다. 1992년도 종자에서 이형주를 제거하고 원형의 개체로부터 자식종자를 대량으로 채종하였다. 함께 공시한 AC2258은 순수한 것으로 확인되었다. 1995년도 채종 CM334 종자에서는 비록 혼종은 되었으나 측지발생이 적은 개체들이 발견되어 이들을 개체 선발하여 역병에 저항성이며 측지발생이 적은 계통으로 육성하고 있다. A total of 31 c. chinense lines selected from 2000 screening were tested again for resistance to P. capsici but resistance was not found in the lines. A total of 26 selections from Korean land races tested 2001 spring were tested again for resistance to P. capsici. KC180, KC230, KC195 and KC194 showed moderate resistance to P. capsici. However, it was apparent on the basis of hortivultural characteristics that KC180 and KC230 had been naturally crossed with AC2258 and CM334, respectively. CM334 and AC2248 seed lots that were increased in different years were taken out and tested for resistance to improve their genetic purity because the resistant genetic resources have been showing some off-types in the population. Off-types began to be found in 1992 seed lots and the proportion and degree of the offs was increasing with time up to 2001. Plants true to the type in 1992 seed lots were selected and their inbred seeds were mass produced in a net cage in the greenhouse. AC2258 included in the experiment number of lateral branching at cotyledonary axil, although they were off from the original in the experiment together was uniform. In 1995 seed lost of CM334, plants with resistance to P. capsici and low or no number of lateral branching at cotyledonary axil, although they were off from the original CM334, were found and selection was applied to breed lines fixed in the characters.

영상 감시 시스템에서의 개선된 Tearing 현상 방지 디스플레이 시스템

이동학,정연권,정선태 崇實大學校 生産技術硏究所 2001 論文集 Vol.31 No.-

In display systems employing an analog monitor, the tearing artifact such that an window screen is divided into two parts showing different scenes can occur when the change of scenes in the moving pictures is very fast, but the frame buffer's refresh rate does not match the monitor's scanning frequency. In the DVR system, a recently popularized visual monitoring system, the tearing artifacts becomes more serious since the frame buffer's refresh rate is vey high due to the requirement of multi-channel display. In this paper, we propose an improved display system for windows-based DVR systems which prevents the tearing artifacts without daterioration of display speed perfromance. The efficiency of the proposed display system is verfied through experiments.
