오주은 ( Ju Eun Oh ),여미영 ( Mi Young Yeo ) 한국노인의료복지학회 2010 노인의료복지연구 Vol.1 No.3
This study alms at analyzing the general characteristics of the seniors to figure out the influence of the health related behavior of the seniors, that is, health acknowledgment, health improvement behavior and health interests in the life the seniors and find out the relationships of their general characteristics, health related behavior, self-esteem and satisfaction of life, looking at the differences of satisfaction of life according to the general characteristics and self-esteem and the factors that influence the satisfaction of life. Delving into the relationships between the health related behavior according to the general characteristics(health perception, health improvement behavior, and health interests) and self-esteem and factors of satisfaction in life, among the health related behavior according to the general features, health perception appeared to affect the health perception when they receive lots of monthly allowances and their subjective physical status is good. Among the health related behavior according to the general features, for the health improvement behavior, female seniors between 60~64, with lots of monthly allowance, with their subjective health status good had good dietary habit, were interested much in exercise, were participating directly in exercise, were active in personal sanitation and disease prevention, had good interpersonal relationships, and were good at controlling their stress. Female seniors were showing more interest in health interests among the health related behavior according to the general features, and there was no significant factor between self-esteems according to the general features. In the satisfaction of life according to the general features, female seniors in their 65~69, with lots of monthly allowances and with good subjective health status showed high satisfaction in life. The satisfaction of life for the seniors appeared high when they are women, when they receive high monthly allowances, their subjective physical status is good, their perception of health is good, they have a lot interest in exercise, they participate directly in exercise, and when they control stress well.

포도 4배체 ‘후지미노리’와 3배체 ‘썸머블랙’의 교배로 얻은 미숙배의 기내배양
고재철(Jae Chul Koh),오주은(Ju Eun Oh) 한국원예학회 2013 원예과학기술지 Vol.31 No.3
포도 4배체 ‘Fujiminori’에 3배체 ‘Summer Black’을 인공교배하여 얻은 미숙배의 발아 및 식물체 분화를 목적으로 MS 배지에 GA3와 Coconut water(CW)를 농도별로 첨가하여 배배양을 실시하였다. ‘Fujiminori’에 ‘Summer Black’을 교배하여 64.3%의 미숙배를 얻을 수 있었고, 미숙배를 기내 배양한 결과 GA3 모든 처리구(0.01, 0.05, 0.25, 1.25mg·L<SUP>-1</SUP>)에서는 95% 이상의 발아율을 나타내었으나, 15.8-31.6%만이 정상적인 식물체로 생장하였다. 또한 GA3의 농도가 높아질수록 하배축은 신장되었고, 비대생장은 억제되었다. CW 모든 처리구(5, 10, 15, 20%) 중에 CW 10%와 CW 15% 처리구에서는 각각 68.4%와 66.7%로 많은 식물체를 획득할 수 있었다. 또한 줄기의 길이생장, 마디수, 발근수는 CW 10% 처리구에서, 뿌리길이는 CW 15% 처리구에서 양호한 결과를 나타내었다. 따라서 포도 4배체 ‘Fujiminori’와 3배체 ‘Summer Black’의 인공교배를 통해 얻어진 미숙배의 발아 및 생장을 위해서는 CW 10-15%를 첨가한 MS 배지를 이용한 배배양이 효과적이다. For the germination and differentiation of immature embryos obtained by artificial crossing between tetraploid grape ‘Fujiminori’ (Vitis vinifera × V. labruscana) and triploid ‘Summer Black’ (V. labruscana × V. vinifera), were incubated in vitro using MS medium supplemented with GA3 or coconut water (CW) at various concentrations. The percentage of embryo formation of ‘Fujiminori’ × ‘Summer Black’ was 64.3%. Embryo germination percentage was higher than 95% in all the GA3 treatments at the concentrations of 0.01, 0.05, 0.25, and 1.25 mg·L<SUP>-1</SUP>. However, only 15.8-31.6% of the germinated embryos successfully developed into normal plantlets. At higher concentration of GA3, the plantlets developed infirm hypocotyls with over elongated and less enlarged structure. Among the treatments of CW at the concentrations of 5, 10, 15, and 20% (v/v), 10% and 15% were more effective and plantlet achievement percentage were 68.4 and 66.7%, respectively. The addition of 10% CW was most effective to obtain plantlets with optimal shoot length, node and root numbers. 15% CW was suitable to obtain plantlets with longer roots. Accordingly, the embryo culture using the MS medium supplemented with 10-15% CW was observed to be more efficient for germinating and growing the immature embryos produced from artificial crossing between tetraploid grape ‘Fujiminori’ and triploid ‘Summer Black’.
