Understanding the functional roles of temporal Hebbian plasticity has been of growing interest since several experiments revealed that the change in synaptic efficacy was determined by the precise temporal relation between post- and presynaptic spikes. We here investigate the learning properties of the typical synaptic modification forms. We explain how the peculiar characteristics in synaptic modification, such as asymmetry, decay rate, and oscillatory behavior, exert effects on the direction and the performance of network formation. Also, we argue that the aforementioned characteristics help to achieve proper network adaptation, such as activity-dependent columnar organization, through an efficient competitive learning process. © 2014 The Korean Physical Society.

Background: Estimation of physical activity contributes to early screening and prevention of decrease in body function. This study was conducted to examine the reliability and validity of the International Physical Activity Questionnaire (IPAQ) short form in elderly people. Methods: A total of 55 outpatients of 65 years old or older participated in this study. Physical activity over the last seven days was recorded on the IPAQ short form. Responses were converted to metabolic equivalent task minutes per week. The IPAQ short form was validated against accelerometer measurements as a gold standard. The test-retest method was performed over a two-week interval to examine the reliability of the IPAQ. Results: The more physically active by the IPAQ short form, the higher the measured value of the accelerometer (P < 0.001). Pearson's correlation coefficient was 0.43 for the correlation between the results of two measurements. Spearman Rho coefficients and Kappa values of test-retest reliability in five elements (vigorous days, vigorous minutes, moderate days, moderate minutes, and walk days) were 0.299-0.605 and 0.307-0.418, respectively. Conclusion: The validity of the IPAQ short form was proven, but the reliability was found to be low. Nevertheless, IPAQ short form seems worthwhile tool for the measurement of physical activity levels, concerning daily variation in physical activity of the elderly. © 2012 The Korean Academy of Family Medicine.

The purpose of this study was to investigate how advanced maternal age influences lifestyle, nutrient intake, iron status, and pregnancy outcomes in pregnant women. The subjects of this study were 112 pregnant women who were receiving prenatal care at gynecologists located in Seoul. The subjects were divided into two groups according to their ages: those over age 35 were the advanced age group of pregnant women (AP) and those under age 35 were the young age group of pregnant women (YP). General factors, nutrient intakes, iron status, and pregnancy outcomes of the two groups were then compared. It was found that 72.5% of the YP group and 51.2% of the AP group had pre-pregnancy alcohol drinking experience; indicating that the YP group had more pre-pregnancy alcohol consumption than the AP group (P < 0.05). The only difference found in nutrient intake between the two groups was their niacin intakes which were 16.83 ± 8.20 mg/day and 13.76 ± 5.28 mg/day, respectively. When gestational age was shorter than 38.7 weeks, the average infant birth weight was 2.95 ± 0.08 kg, and when gestational age was longer than 40 weeks, it averaged at about 3.42 ± 0.08 kg. In other words, as gestational age increased, infant birth weight increased (P < 0.0001), and when maternal weight increased more than 15 kg, the infant birth weight increased significantly (P < 0.05). In conclusion, in order to secure healthy human resources, with respect to advanced aged women, it is necessary to intervene by promoting daily habits that consist of strategic increases in folate and calcium intake along with appropriate amounts of exercise. © 2011 The Korean Nutrition Society and the Korean Society of Community Nutrition.

Purpose A better understanding of the factors contributing to smoking cessation would be of substantial benefit to public health. The purpose of this study was to identify significant predictors of successful smoking cessation in the Korean population. Methods We compared 1,181 successful quitters with 940 current smokers who made a recent attempt to quit but failed in the past 12 months using the fourth Korea National Health and Nutrition Examination Survey. We examined the relationship of sociodemographic, behavioral and environmental characteristics, comorbid conditions, and quitting methods to successful smoking cessation. Results Older age, female, being married, having higher education, having a lower level of stress, having smoked 20 or more cigarettes per day, and one's own will for quitting have been identified as significant determinants of successful cessation. Frequency of alcohol consumption and trying numerous quitting methods was inversely related to stopping smoking. Conclusion This study suggests that cessation programs need to take a holistic approach and should consider these factors in setting up. © 2013, Korean Society of Nursing Science.

This paper uses the instrumental variable threshold regressions approach of Caner and Hansen (2004) to investigate whether the trade's contribution to the standard of living and long-run economic growth varies according to the level of economic development. The empirical evidence shows that greater trade openness has strongly beneficial effects on growth and real income for the developed countries but significantly negative effects for the developing countries. The heterogeneity in the relationships suggests that greater international trade and integration may foster uneven development and hence contribute to more diverging economies. In addition, the link of trade to economic performance is found to work through both capital accumulation and productivity growth channels. Finally, the evidence shows that real effects of trade also depend on the level of financial development, inflation and trade openness. © 2011 Taylor & Francis. Source
