      • 2-Aldobenzimidazole 誘導體의 合成과 抗菌性

        金相烈,마은숙 대구효성가톨릭대학교 자연과학연구소 1989 基礎科學硏究論集 Vol.3 No.-

        Four 2-(aldopolyhydroxyalkyl)benzimidazole derivatives were synthesized from o-phony-lenediamine and aldose (D-galactose, D-mannose. L-rhamnose, L-arabinose) , by the use of cupric acetate as oxidizing agent and then investigated their structure and antimicrobial activities. The structure of 2-aldobenzimidazoles are estimated by UV, IR, NMR spectra. In the NMR spectra, the proton of C-1'OH neighbored at benzimidazole ring was downfieldshifted relative to other OH protons and the proton of C-1'OH of manno-, rhamno-benzimidazole, which is neighbored at C-2'OH, were low-shifted than two compounds. In vitro, the result of antimicrobial activity was shown that four compounds have antimic-robial activity against St. aureus, P. vulgalis, E. coli, Sal. typhi at 4-12mg/ml and antifunfal activity against Cryp. neoformans at 8mg/ml.

        단미벼의 발아 특성 및 기계이앙 육묘시 적정 파종량

        김상열,오성환,이종희,정국현,조준현,이지윤,박성태,송유천,여운상,김정일,서우덕,강항원 한국작물학회 2010 Korean journal of crop science Vol.55 No.2

        천립중이 가벼워 수량은 낮으나 sucrose와 glucose함량이 상대적으로 높아 환자의 이유식 등의 사용을 목적으로 개발된 단미 벼 종자의 발아 및 출아특성과 기계이앙 상자육묘시 적정 파종량을 구명하기 위한 시험결과는 다음과 같다. 1. 단미의 비중별 분포비율은 1.0이하로 가벼운 종자가 97.4%로 대부분이었고 1.12이상인 충실한 종자비율은 2.0% 이하로 낮았다. 반면 일미벼는 단미와 달리 1.12이상 충실한 종자의 비율이 82.3%로 가장 높았고 1.0이하의 충실하지 못한 종자의 비율은 6.4%로 낮았다. 2. 비중별 발아율은 단미의 경우 88-91%로 비중에 관계없이 비슷하였으나 일미벼의 발아율은 단미와 달리 1.0이하는 24%, 1.0~1.12는 61~66%, 1.12이상은 93%로 종자 비중이 무거울수록 발아율이 높았다. 3. 발아속도도 단미 및 일미벼 모두 발아율과 비슷한 경향을 나타냈으나 비중이 1.12이상일 경우 일미벼의 발아속도는 단미보다 빨랐다. 4. 육묘를 위한 단미의 침종기간은 침종온도에 관계없이 일미벼보다 2~4일 더 길었다. 5. 단미는 일미벼에 비해 정상모의 비율이 낮고 비정상모의 비율이 높았는데 비정상모중에서 출아불량이 4.9%, 출아후 shoot의 생육정지는 4.7%, 출아후 생육불량모는 5.3%로 높았다. 6. 기계이앙 육묘시 단미의 적정 파종량은 관행 일미벼 어린모 및 중묘의 상자당 성묘개체수를 기준으로 볼때 관행과 같이 어린모는 220g, 중묘는 130g이었고 부피로는 육묘일수에 관계없이 관행 일미벼의 1.5배량이었다. A high sugar rice cultivar 'Danmi' which has been recently developed and released in the Functional Crop Resource Development Division, Department of Functional Crop, National Institute of Crop Science, has high glucose and sucrose contents but has a poor seed development. This defect poses some problem in ensuring stable seedling establishment in the nursery bed. We examined the germination and seedling emergence characteristics of 'Danmi' and determined an optimum seeding rate for seedling establishment. 'Danmi' seeds has a light 1,000-grain weight of 18.2g compared with Ilmibyeo's 26.7g. The 97.4% of 'Danmi' seeds has specific gravity below 1.0 while only 2.0% of seeds was fully developed with specific gravity above 1.12. However, the reverse is true in the Ilmibyeo seed used as a control cultivar. Although the seed germination of Danmi was 89-91% regardless of seed specific gravity but at a slower rate than Ilmibyeo regardless of water soaking temperatures of 20-30~circC because of high seed amount of specific gravity below 1.0 in 'Danmi'. It took 2~4 days longer of seed soaking in the Danmi seeds than Ilmibyeo before germination. 'Danmi' has low normal seedling emergence rate than Ilmibyeo in the seedbed soil due to high percentage of abnormal seedlings like stunting and incomplete growth. Normal seedling emergence rate of 'Danmi' in the seedbed was 62.6~64.9% for 10-day old seedling and 83.5~86.7% for 30-day old seedling which is lower by 29.6~30.0% and 11.3~12%, respectively than Ilmibyeo. Although 'Danmi' has low normal seedling emergence rate, but it has greater seed number per weight basis. Therefore, based on the normal seedling number per unit area of Ilmibyeo(control cultivar) for seedling rate of 10-day and 30-day old seedlings, the recommended seeding rate of 'Danmi' for transplanting rice is 220g seeds for 10-day old seedling and 130g for 30-day old seedling per nursery box, which is equivalent to 1.5 times seed volumes of Ilmibyeo.

        (NH_4)_2 SO_4의 誘電特性과 赤外線 反射 스펙트럼

        金尙烈,曺吉鎬 陸軍士官學校 1979 한국군사학논집 Vol.19 No.-

        The behavaiors of dieletric properties of (NH_4)_2 SO_4(유안) have been studied. The curves of dielectric constant v.s temperature do not obey the Curie-Weiss law except in the close vicinity of transition temperature with very small value of Curie constant. The shift of transition temperature on the d.c. bias field has not been detected. Infrared reflectivity measurement in the spectral region 400~4000cm^-1 at room temperature was carried out. The relectivity spectrum was subject to the Kramsers-Kronig analysis and the mode parameters of the three lattice vibrations were determined. From the comparison of the low frequency dielectric constant, it was confirmed that no dispersion occurs in the region of 1~30cm^-1

        Effect of supportive periodontal therapy on the prevention of tooth loss in Korean adults

        김상열,이재관,장범석,엄흥식 대한치주과학회 2014 Journal of Periodontal & Implant Science Vol.44 No.2

        Purpose: The purpose of this retrospective study was to evaluate the effect of patientcompliance with supportive periodontal therapy (SPT) on tooth loss in Korean adults. Methods: The periodontal records of 134 patients were reviewed for this study. They completedactive periodontal treatment from 1999 to 2001 and were placed on a schedule ofperiodic follow-up visits for SPT. Patient compliance was classified into complete compliance(CC), erratic compliance (EC), and noncompliance (NC) groups. Re-examinations werecarried out 11.0±0.8 years after the active periodontal treatment. The prognosis for eachtooth was determined as good, questionable, or hopeless according to the bone loss observedin pretreatment radiographs. Results: The rate of tooth loss of the CC group was significantly lower than that of the NCgroup. The tooth loss/patient and the tooth loss/patient/year were not significantly differentbetween the three groups. The rates of tooth loss in the good, questionable, and hopelessprognosis groups were 6.7%, 9.5%, and 13.2%, respectively. For the teeth with a goodprognosis, the rate of tooth loss of the CC group was significantly lower than that of theNC group (0.4% vs. 5.1%). For the teeth with a questionable prognosis, the CC groupshowed a significantly lower rate of tooth loss than did the EC group (4.1% vs. 30.7%) orthe NC group (4.1% vs. 25.6%). For the teeth with a hopeless prognosis, the rates of toothloss were not significantly different among the three groups. Conclusions: Within the limits of this study, the patients who showed a poor compliancewith SPT were more likely to lose teeth than were the regularly compliant patients. However,the risk of tooth loss with a hopeless prognosis was high irrespective of the compliance.

        Rice cultivars adaptable for rice based cropping systems in a paddy field in the Yeongnam plain area of Korea

        김상열,서종호,배현경,황정동,고종민 충남대학교 농업과학연구소 2018 Korean Journal of Agricultural Science Vol.45 No.3

        This study was conducted to investigate suitable rice cultivars for various rice based cropping systems in a paddy field in the Yeongnam plain area. Thirteen rice cultivars (5 early, 3 medium and 5 mid-late maturing cultivars) and three transplanting dates (June 5, June 25 and July 5) were evaluated in this study. The mid-late and early maturing cultivars for the July 5 and June 25 transplanting headed before August 30 which is the safe heading date in the Yeongnam plain area, ranging from Aug. 26 - 28 and Aug. 18 - 23, respectively. The safe harvest time of rice for double and triple cropping systems should be before the middle of October for the cultivation of the succeeding winter crops. The rice yield was the highest for the June 5 transplanting regardless of the rice cultivars, and it gradually decreased as the transplanting date was delayed from June 5 to July 5 due to a decrease in the spikelet numbers per panicle number and in the ripened grain rate. In contrast, the other yield parameters that include the panicle number per m2, the 1,000-brown rice weight, and the ripened grain ratio were not significantly affected. The result indicates that based on the milled rice, heading time and harvest time, a medium maturing cultivar (Haiami and Samdeog) would be applicable to a winter barley/wheat, garlic/onion-summer rice double cropping, while a mid-late cultivar (Saeilmi, Saenuri and Hyunpoom) would be suitable for a spring potato/waxy corn-summer rice double cropping in the Yeongnam plain area. On the other hand, an early maturing cultivar (Unkwang, Jokwang and Haedamssal) would be preferable for a triple cropping because of the short growth period of rice.
