  • A mammary epithelial cell line (MAC-T) established as a model for lactation was utilized to identify and characterize effects of various hormones upon insulin-like growth factor binding protein secretion. Ligand and immunoblot analyses of conditioned media indicated that insulin-like growth factor binding protein-2 was secreted by MAC-T cells. Insulin-like growth factor-I stimulated insulin-like growth factor binding protein-2 secretion in a dose-dependent manner, but prolactin and bovine somatotropin did not alter insulin-like growth factor binding protein-2 secretion. Insulin increased and cortisol decreased insulin-like growth factor binding protein-2 secretion. Effects of insulin-like growth factor-I on insulin-like growth factor binding protein-2 secretion support previous studies using primary cultures of bovine mammary cells and bovine fibroblasts. Effects of cortisol and insulin on insulin-like growth factor binding protein-2 secretion may be explained by changes in protein synthesis. In addition, supraphysiological doses of insulin can cross-react with the insulin-like growth factor-I receptor and stimulate insulin-like growth factor binding protein-2 secretion. MAC-T cells provide a model system to study mechanisms that regulate local insulin-like growth factor-I bioactivity.

  • This study aims to analyze the effects of trade on human capital accumulation and economic growth in Korean manufacturing industry. The results of empirical analysis by dynamic panel model are as follows. The increase in exports of skilled labor intensive industries has a positive effect on human capital and economic growth, and the impact of import on human capital accumulation and economic growth has alst a positive impact. The exports of unskilled intensive labor industries have a negative impact on human capital accumulation and economic growth. Imports of unskilled labor intensive industries have negative on human capital accumulation and economic growth. It is difficult to derive statistically significant results for the effects of trade on human capital accumulation and economic growth before and after 2008. However, as a result of the financial crisis in 2008, it seems that the effects have decreased since 2008.

  • Phytobiotics, also known as phytochemicals or phytogenics, have a wide variety of biological activities and have recently emerged as alternatives to synthetic antibiotic growth promoters. Numerous studies have reported the growth-promoting effects of phytobiotics in chickens, but their precise mechanism of action is yet to be elucidated. Phytobiotics are traditionally known for their antioxidant activity. However, extensive investigations have shown that these compounds also have anti-inflammatory, antimicrobial, and transcription-modulating effects. Phytobiotics are non-nutritive constituents, and their bioavailability is low. Nonetheless, their beneficial effects have been observed in several tissues or organs. The health benefits of the ingestion of phytobiotics are attributed to their antioxidant activity. However, several studies have revealed that not all these benefits could be explained by the antioxidant effects alone. In this review, I focused on the bioavailability of phytobiotics and the possible mechanisms underlying their overall effects on intestinal barrier functions, inflammatory status, gut microbiota, systemic inflammation, and metabolism, rather than the specific effects of each compound. I also discuss the possible mechanisms by which phytobiotics contribute to growth promotion in chickens.

  • Objectives : This study was designed to investigate the effects of horse bone powder extract on the growth of longitudinal bone in adolescent male rats. Methods: Longitudinal bone growth was measured by fluorescent microscopy. To examine the effects on the growth plate metabolism, the total height of growth plate, the induction of local insulin-like growth factor-1 (IGF-1), and bone morphogenetic protein-2 (BMP-2) were measured. Results: Horse bone powder extract enhanced longitudinal bone growth and total height of the growth plate. Also, it promoted the induction of local IGF-1 and BMP-2 of the growth plate. Conclusions: This study shows that the horse bone powder extract effects longitudinal bone growth in adolescent rats and might be used for both stunted adolescents and inherent growth failure patients.

  • Plant growth is considered the sum of cell proliferation and subsequent elongation of the cells. The continuous proliferation and elongation of plant cells are vital to the production of new organs, which have a significant impact on overall plant growth. Accordingly, the relationship between environmental stimuli, such as temperature, light, wind, and sound waves to plant growth is of great interest in studies of plant development. Sound waves can have negative or positive effects on plant growth. In this review paper we have summarized the relationship between sound waves and plant growth response. Sound waves with specific frequencies and intensities can have positive effects on various plant biological indices including seed germination, root elongation, plant height, callus growth, cell cycling, signaling transduction systems, enzymatic and hormonal activities, and gene expression.

  • To elucidate the effects of a hydroelectric dam construction on annual ring growth of Pinus densiflora, the annual ring widths of 68 trees collected from 7 sites were closely examined. The result was analyzed to ask three special questions first, whether there are real effects of dam construction on the radial growth second, would the magnitude of the effect be different due to two periods of under-construction and post-construction the last, would it be different among age classes. Annual ring growth has been significantly enhanced by the dam construction. Specially, its effect was marked after the construction was finished and the reservoir was filled up with water. There was, however, no remarkable evidence that pine growth would be reduced while the dam was under construction, even though there was a minor decreasing trend. The magnitude of the effect was different among age groups. That is, the changed condition after the construction enhanced relatively the growth of aged trees monre. According to other meterological research since the dam was constructed, the reasons of enhancing pine growth assumed to be the increase of daily temperature, the decreased of daily temperature difference and the increased of rainy days.

  • Purpose: The objective of this study is to identify the effects of self-esteem and problem focused coping on post-traumatic growth among police officers. Methods: The data were collected from the 137 police officers in ten police offices of G city in July 2014. The collected data were analyzed for descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and hierarchical regression using the SPSS/WIN 18.0 program. Results: Post-traumatic growth was positively correlated with self-esteem and problem focused coping. Self-esteem and problem focused coping had a significant effects on post-traumatic growth. The explained variance for post-traumatic growth was 19.0%. Conclusion: To improve post-traumatic growth of police officers, strategies to increase self-esteem and problem focused coping are needed.

  • This study was aimed to investigate the effect of several stimulatory trements of flower and seed growth on the reproductive and vegetative growth of Tilia amurensis RUBP. The effects of mounded planting, girdling, root-pruning, bending and foliar fertilizer application on the fifteen to forty yead-old tress growing in the experimental plantation at the Konkuk University and the National forest at the Daegwanryung were measured. The following results were obtained: (1) The number and the longitydinal growth of internode were reduced by the treatments. The xylem growth of the longitudited more greatly than the bark growth by all the treatments. (2)The increasong rate of the brand angle as compared to that of the control was 2.11% in the girdling treatment, 31.61% in the mounded planting treatment, and 22.14% in root-pruning treatment. (3) The foliar application of fertilizer(N, P, K, and B) before flowering increased leaf and stem growth, that one after pollen fertilization increased the fruit growth. (4)The foliar application of fertilizer before flowering increased the xylem growth while that after pollen fertilization increased the bark growth. (5)The stimulatory effects of root pruning and branch bending on the flowering and seed growth were shown relatively less than that of mounded planting. The effect of the moinded planting on the yield of the seeds has remained continuously every year since planting the trees.
