Purpose: This study aims to test if the age of pregnant women affects the perception, experience, and attitude towards complementary alternative therapy (CAT), by investigating the perception, experience, and attitude of pregnant women under the age of 35, and above 35 (Advanced Maternal Age). The study will 1) find the general characteristics of pregnant women under and over the age of 35 2) compare the perception, behavior, and experience of pregnant women under and over the age of 35, and 3) find the comparison of the perception, behavior, and experience according to the general characteristics of pregnant women under and over the age of 35. Method: The subjects of this study are composed of 44 women under the age of 35 and 44 women above the age of 35, totaling 88 pregnant women visiting midwiferies, obstetrics and gynecology, and baby fairs in Seoul and Gyeong-Gi area. Data for this study was collected from November 28, 2015 to January 6, 2016 for 40 days. The collected data analyzed mean, standard deviation, t test, ANOVA, and chi-square by using SPSS 23.0. Result Results show that there is a significant difference in the perception, attitude, and experience of the two-sample groups in the use of CAT. The question of “what is most necessary when applying CAT in a hospital clinical environment” for the perception criteria came out with the results of t=9.980, p<.05. For the attitude, results showed that the answers of pregnant women under the age of 35 displayed a more positive attitude towards CAT. (t=2.421, p<.05) Lastly, in the experience section, pregnant women under the age of 35 showed more CAT use than the other sample group. Conclusion Results have shown that there is a difference in the perception, behavior, and experience between the two sample groups. Therefore further research on the efficacy and the adverse effects of CAT needs to be done.

Purpose: Physical activity and satisfaction of school life at an adolescent period are important both for student athletes and ordinary students. Also gap of the amount of the physical activities between them is clear. This study has the objective in looking at difference of satisfaction at school life among general high school students and student athletes according to the amount of physical activities. Method: This study selects sport high schools and general high schools at Seoul and Incheon area as population for analyzing school life satisfaction according to appropriate amount of physical activities at adolescent period. The method of sampling is simple random sampling of probability sampling and by using this method, this study collected 400 general students and 350 student athletes: total 750 students. The study constitutes a survey focused on social background, physical activities and the factors for school life satisfaction. And the method for survey is self-administration method. The study conducted descriptive analysis and exploratory factor analysis for 594 surveys (excluding unreliable data with insincere answers, double answers and without response) for validity and reliability. For the last, the research was analyzed by MNOVA and SPSS23.Over Program. Result: First, the average amount of physical activities of high school students is 8,712METs based on GPAQ and it is quite high amount since it includes student athletes. Second, there is a statically clear gap of daily physical activities among general students and student athletes as a result of physical activity analysis based on student type. Also male students show higher average at leisure, work and total amount of physical activities than female students. Third, the amount of physical activities according to sports type shows high amount at Taekwondo, Swimming, Judo order and Shooting, Archery show the lowest. Fourth, there is no clear difference of school satisfaction according to gender and physical activities, and also student types and physical activities. However, student athletes and general students show higher satisfaction when they do physical activities. Conclusion: The amount of physical activities of object high school students for this study shows seven times higher than recommended amount of WHO for adolescent and two times higher for average amount. WHO recommend 75 minutes of extensive workout including daily workout and movement: walking, cycling and sports activities, to adolescent. However, general students do not satisfy this with lack of amount of physical activities and student athletes are practicing extreme level of workout. It is natural for student athletes but extreme and continuous physical activities can result negative effect for the adolescent. Keer (1988) and Jeong (2006) said that extreme training at adolescent period results critical and various injuries that student athletes may not maintain life as athletes. Therefore, it is necessary to reduce unnecessary physical activities and to establish effective workout method. On the other hand, for the general students, they tend to have lower amount of physical activities by the study-focused atmosphere and it is problematic. Kim (2013) said that it is important to make a joy and value for getting together by school physical education for students to participate actively. The efforts for increasing the physical activities at school are required. According to the gender, male students show higher amount of physical activities than female students. It corresponds to a result of the research that analyzed amount of physical activities according to the area by Kim (2007) and the research that analyzed male and female adolescents by Lim (2014). Male students have high interest in physical and workout capability development at growing period, while female students tend to avoid physical activities and show passive attitude toward physical activities Kim (2012). Also the education to utilize leisure time as meaningful workout time and instruction of teachers to encourage the interest for various sports is necessary for students.

Procoagulant and prothrombotic activation of human erythrocytes by phosphatidic acid

Noh, Ji-Yoon,Lim, Kyung-Min,Bae, Ok-Nam,Chung, Seung-Min,Lee, Sang-Wook,Joo, Kyung-Mi,Lee, Sin-Doo,Chung, Jin-Ho American Physiological Society 2010 American journal of physiology, Heart and circulat Vol.299 No.2

<P> Increased phosphatidic acid (PA) and phospholipase D (PLD) activity are frequently observed in various disease states including cancers, diabetes, sepsis, and thrombosis. Previously, PA has been regarded as just a precursor for lysophosphatidic acid (LPA) and diacylglycerol (DAG). However, increasing evidence has suggested independent biological activities of PA itself. In the present study, we demonstrated that PA can enhance thrombogenic activities in human erythrocytes through phosphatidylserine (PS) exposure in a Ca<SUP>2+</SUP>-dependent manner. In freshly isolated human erythrocytes, treatment of PA or PLD induced PS exposure. PA-induced PS exposure was not attenuated by inhibitors of phospholipase A2 or phosphatidate phosphatase, which converts PA to LPA or DAG. An intracellular Ca<SUP>2+</SUP> increase and the resultant activation of Ca<SUP>2+</SUP>-dependent PKC-α appeared to underlie the PA-induced PS exposure through the activation of scramblase. A marginal decrease in flippase activity was also noted, contributing further to the maintenance of exposed PS on the outer membrane. PA-treated erythrocytes showed strong thrombogenic activities, as demonstrated by increased thrombin generation, endothelial cell adhesion, and erythrocyte aggregation. Importantly, these procoagulant activations by PA were confirmed in a rat in vivo venous thrombosis model, where PA significantly enhanced thrombus formation. In conclusion, these results suggest that PA can induce thrombogenic activities in erythrocytes through PS exposure, which can increase thrombus formation and ultimately contribute to the development of cardiovascular diseases. </P>

Layer-by-layer assembled multilayers of charged polyurethane and graphene oxide platelets for flexible and stretchable gas barrier films

Noh, Min Ji,Oh, Min Jun,Choi, Jae Ho,Yu, Jae Chul,Kim, Woo-Jae,Park, Juhyun,Chang, Young-Wook,Yoo, Pil J. The Royal Society of Chemistry 2018 Soft matter Vol.14 No.32

<P>With the advent of the era of consumer-oriented displays and mobile devices, the importance of barrier film coatings for securing devices from oxygen or moisture penetration has become more salient. Recently developed approaches to generate gas barrier films in a combination of polyelectrolyte multilayer matrices and incorporated inorganic nanosheets have shown great potential in outperforming conventional gas barrier films. However, these films have the intrinsic drawback of vulnerability to brittleness and inability to stretch for flexible device applications. To overcome this issue, we present a method in which we prepare multilayered films of complementarily charged polyurethane and graphene oxide platelets using spin-assisted, layer-by-layer self-assembly to obtain well-stacked film structures. As a result, the multilayered, thin films deposited on a poly(ethylene terephthalate) (PET) substrate can exhibit significantly reduced oxygen penetration properties (∼30 cc m<SUP>−2</SUP> day<SUP>−1</SUP> for the oxygen transmission rate) while still demonstrating large bending or stretching deformations. Therefore, the proposed approach in this study is anticipated to be extensively utilized for surface coating and protection of flexible and stretchable devices under various operating conditions.</P>

( Ji Na Park ),( Ji Sun Lee ),( Min Young Noh ),( Mi Kyung Sung ) 한국임상영양학회 2015 Clinical Nutrition Research Vol.4 No.4

This study aimed to explore the correlation between usual vitamin K intake and response to anticoagulant therapy among pa-tients under warfarin therapy. We conducted a retrospective survey of patients (n = 50) on continuous warfarin therapy. Clini-cal information and laboratory parameters were sourced from medical records. Anticoagulant effect was evaluated by using the percent time in therapeutic range (TTR) and the coefficient of variation (CV) of International normalized ratio (INR). Dietary vitamin K intake was assessed using a semi-quantitative food frequency questionnaire that has been developed for the purpose of assessing dietary intake of vitamin K. A total of 50 patients aged between 21 and 87 years were included in the study. The mean vitamin K intake was 262.8 ± 165.2 μg/day. Study subjects were divided into tertiles according to their usual vitamin K intake. The proportion of men was significantly higher in second and third tertile than first tertile (p = 0.028). The mean percent TTR was 38.4 ± 28.4% and CV of INR was 31.8 ± 11.8%. Long-term warfarin therapy group (≥ 3 years) had a higher percent-age of TTR as compared to the control group (< 3 years) (p = 0.046). No statistically significant correlation was found between usual vitamin K intake and percent TTR (p > 0.05). In conclusion, no significant association was observed between usual vita-min K intake and anticoagulant effects. Further studies are required to consider inter-individual variability of vitamin K intake. Development of assessment tools to measure inter-individual variability of vitamin K intake might be helpful.

Ji Yeon Yu,Yong-Ri Jin,이정진,정진호,Ji-Yoon Noh,Soon-Hyang You,김기남,Ji-Hyun Im,Ju-Hyun Lee,Ji-Min Seo,Hyeong-Jun Han,임용,Eun-Seok Park,김택중,신경섭,Jae-Joon Wee,Jong-Dae Park,윤여표 대한약학회 2006 Archives of Pharmacal Research Vol.29 No.10

The antiplatelet and antithrombotic activities of Korean Red Ginseng (KRG) were examined on rat carotid artery thrombosis in vivo, and platelet aggregation in vitro and ex vivo. Administration of KRG to rats not only prevented carotid artery thrombosis in vivo in a dose-dependent manner, but also significantly inhibited ADP- and collagen-induced platelet aggregation ex vivo, while failed to prolong coagulation times such as activated partial thromboplastin time (APTT) and prothrombin time (PT), indicating the antithrombotic effect of KRG might be due to its antiplatelet aggregation rather than anticoagulation effect. In line with the above observations, KRG inhibited U46619-, arachidonic acid-, collagen- and thrombin-induced rabbit platelet aggregation in vitro in a concentration-dependent manner, with IC50 values of 620 ± 12, 823 ± 22, 722 ± 21 and 650 ± 14 μg/mL, respectively. Accordingly, KRG also inhibited various agonists- induced platelet serotonin secretions as it suppressed platelet aggregation. These results suggest that KRG has a potent antithrombotic effect in vivo, which may be due to antiplatelet rather than anticoagulation activity, and KRG intake may be beneficial to the individuals with high risks of thrombotic and cardiovascular diseases.
