      • 배지의 무기염류와 sucrose 농도가 감자의 기내 shoot 증식과 기내경 삽목묘의 생존율에 미치는 영향

        김희곤,임순희,안장순,송창길,박미경,강봉균 全南大學校 農業科學技術硏究所 1999 農業科學技術硏究 Vol.34 No.-

        감자의 virus-free 기내경 삽목묘의 효율적인 대량 생산 체계의 확립을 위하여 생장점 배양으로 얻어진 감자의 기내경의 증식과 기내경의 순화삽목을 실시한 결과는 다음과 같다. 초대배양에서는 염류농도와 sucrose 농도가 높을수록 양호하였다. 즉, MS나 2MS에 sucrose를 6% 첨가한 배지에서 튼튼한 기내경이 생산되었다. 계대배양에서는 sucrose 농도가 높을수록 줄기의 길이는 단축되고 굵기는 커졌으며 생체중은 염류농도와 관계없이 3%의 sucrose가 첨가된 배지에서 무거웠다. 이들 유식물체의 경절을 삽목한 결과 계대배양 배지의 sucrose농도가 6%인 배지에서 생존율이 높은 경향이었다. In order to establish a mass propagation system of potato planting material, in vitro multiplication of virus-free shoot originated from meristem culture and sucrose concentrations on survival of cutting of the in vitro stem tried with various media containing different levels of MS salts(0.5x, 1x and 2x) and sucrose(1.0, 3.0, 6.0%), and the effects of MS salts elements were evaluated. Higher level of sucrose in the initial culture media favored the shoot growth, that is, both of 1MS and 2MS media containing 6.0% sugar produced stouter shoots. Higher level of sucrose in the subculture media also favored the development of compact stout shoots, but biomass production in terms of fresh weight was high on the media containing 3.0%sucrose, regardless of MS salts concentration. The survival rate of cuttings made of the in vitro stem segments tended to be higher in those obtained from subculture media containg 6.0%sucrose.

        Background: Recently, patients' demands for emergency medicine are increasing, and most of prehospital medical care, including basic life support, cardiopulmonary resuscitation and triage, are provided by paramedics or emergency medical technicians. Evaluation of the adequacy of prehospital management and triage has become important for improving the quality and the effectiveness of the emergency medical system. Methods: The 202 patients who were transferred by ambulance with paramedics, nurses, or emergency medical technicians to the Emergency Department in Gil Medical Center from July 1, 1999, to September 31, 1999, were enrolled. This study was conducted prospectively by using the emergency physician,s log and newly devised protocols recorded by paramedics or nurses. Results: 1) Male to female ratio was 1: 0.8, and the peak age of the patients were the 4th(18.8%) and 6th decade(15.3%). 2) Of the 202 patients, 84 patients were transferred for trauma and 118 for medical problems. The mean transfer time was 6±1.73 minutes. 3) The validities of prehospital triage and decisions using the trauma severity measure and the disease severity measure, were 33.3% in trauma patients and 57.6% in medical patients.4) The results for the adequacy rate in prehospital management analyzed by using the rate of necessity of treatment. performance of treatment, and adequate treatment were as follows: oxygen supply.38.1/41.6/93.8 ; wound dressing. 19.3/71.8/92.9 ; immobilization of the cervical spine, 15.8/56.3/92.9 ; application of a spinal board. 12.9/42.3/72.7 ; application of a splint, 9.9/50.0/60.0 ; manual maintenance of an airway. 9.9/55.0/63.6 ; and CPR, 4.5/66.7/0. 5) Kind of ALS(Advanced Life Support) were not conducted(peripheral IV, EKG. intubation, medical administration. defibrillation, pacing). The rates of necessity of treatment were as follows: peripheral IV, 40.6%; ECG monitoring, 23.3% ; endotracheal intubation, 8.9% ; medical administration, 8.9% ; defibrillation. 3.5%; and pacing. 1.5% Conclusion: The adequacy of prehospital triage and decisions using trauma and disease severity measures was relatively low. To improve the adequacy of BLS(Basic Life Support) and to increase the performance of ALS(Advanced Life Support), we must create challenges to develop new protocols and to supplement new equipment.

        신건순 國立金烏工科大學校附設生産技術硏究所 1995 産業技術開發硏究 Vol.11 No.-

        본 논문에서는 차단주파수가 4MHz인 연속시간의 5차 OTA-C Elliptic filter를 설계하였다. 설계된 필터는 OTA-C구조로서 5개의 OTA, 8개의 커패시터와 1개의 완충기로 구성하였다. OTA의 기생커패시턴스 및 Loading에 의한 특성저하를 방지하기 위해 완충기와 커패시터를 설계하여 연결시켰고, 이로인해 주파수특성은 원래의 설계조건, 즉 통과대역 감쇠 0.5dB이하, 저지대역 감쇠 30dB와 차단주파수 4MHz를 모두 만족시켰으며, Pspice(level=3)로 시뮬레이션 했다. 차단특성은 이론적인 경우보다 약 7.4dB만큼 더욱 특성이 개선되었다. 그리고 L-EDITOR를 이용하여 기본 블럭인 OTA와 buffer를 1.5㎛ design rule로 layout 했으며, 기본 블럭들을 이용하여 5차 OTA-C Elliptic filter를 layout 했다. Design of a continuous-time fifth-order OTA-C Elliptic filter for operation at 4MHz is presented. The filter has been realized by five OTAs, eight capacitors and a buffer as an OTA-C structure. To prevent decreasing of characteristics due to the parastic capacitance of OTA and loading a buffer and a capacitor have been connected to the next of second section. As the result of the simulation using LEVEL 3 with PSPICE the frequency characteristics were found to be essentially within specifications : less than 0.5dB passband attenuation, 30dB stopband attenuation and 4MHz cut-off frequency have been obtained and the characteristic of cut-off region has been improved about 7.4dB compared with it of the theoritical case. OTA and buffer layouted with 1.5㎛ design rule using L-EDITOR. And fifth-order lowpass elliptic filter was composed by them.

        The purpose of this study was to investigate the mutual relationship between food preference and nutrient intake status of high school students, based on the their personal characters which are sex, age, family type, number of family, mother's age, occupation, and school career. 439 students were selected with random stratified cluster sampling method. The study used a self-administrated questionnaire and 24-hour recall method for 5 days as instrument tools. Statistical methods applied to analyze the data were frequency, percent, Willcoxon Rank-sum test, Kruskal-Wallies test, χ²-test by contingence table, and Spearman's correlation coefficient in non parametric statistical methods. Some of interesting results are as follows : 1. The correlation between sex and the set of characters of mother's age, school career and income is highly significant. However there is no any significant difference on the kinds of job and the types of family. 2. The relation between the preference of main dishes and the nutrient intake show a significant difference except to the noodles. This marks that preference of main dishes shows a direct proportion with the nutrient intakes except for the fat, vitamin A, vitamin C. 3. The preference of animal food marks a direct proportion with the nutrients such as energy, protein fat, fiber, phosphorus, iron, vitamin B₁, vitamin B₂, and niacin. 4. The preference of vegetable food gives some influence on the nutrient intake but the preference of soup is insignificant, the preference of Kimchi is in reverse proportion, and the preference of vegetable marks a direct proportion with the nutrient intake. 5. The preference of snacks marks a direct proportion with all kinds of nutrients intake except for the vitamin A, and vitamin C.

        이건순,이승교 동아시아식생활학회 1999 동아시아식생활학회지 Vol.9 No.3

        This study was carried out to evaluate high-school students' nutrient intakes according to the status of body mass index, and to analyze the physical health status. The volunteers were 560 high school students in 8 provinces, but 511 students were analyzed. It was used questionnaire method as an instrument tool. The questions were composed with socio-demographic characteristics, physical health condition by CMI, and the evaluation of food consumption by 24 hours recall method. Anthrophometric measurement of height and weight was used the data of health chart of each school-class. The family situation of the subjects was mostly nuclear family(73%), agricultural work(53%), and normal living situation(75%). The students of the BMI range of 18-23 were 71%, but those of the overweight(over 23) were 15%. The individual characteristics were different in BMI. Female and third grade students were more of BMI scores. The overall nutrient intakes of students were low compared with Korean RDA of adolescent, especially iron, calcium, vitamin A, and riboflavin. The mean adequacy ratio(MAR) of nutrient intakes was 0.45±0.23 only. The energy nutrients, ash, and vitamin A intakes were significantly different according to the different BMI groups, But the other mineral and vitamin intakes were not different according to BMI. By the correlation of individual characters with BMI, height was negatively and weight and school grade were positively correlated, but sleeping time and study accomplishment were not correlated. By the correlation of nutrient intakes with BMI, there were negative correlation with the intakes of energy, carbohydrates, potassium, and thiamin. According to this results, We concluded that Korean high-school students living in rural were lower intake of nutrients(iron, vitamin A, and riboflavin) and unbalanced nutrient intakes(MAR of 0.45±0.23). The state of lower intakes of energy nutrients and vitamin A intakes in higher BMI group mean the students spend their effort to reduce BMI for avoiding obesity. But they need to balanced diet, and good nutrient intakes. These situations would be necessary for students to ameliorate quality of living in rural.
