In our previous studies, we demonstrated that Vascular Endothelial Growth Factor (VEGF) enhances bovine oocyte maturation and early embryonic development in serum supplemented media. In this experiment, to determine the synergistic effect of VEGF with serum components on early embryonic development in vitro in cattle, 1 mg/ml polyvinyl-alcohol (PVA) was replaced with foetal bovine serum (FBS) in maturation and culture media. Bovine oocytes were matured in Synthetic Oviduct Fluid (SOF) supplemented with PVA, PVA+5 ng/ml of VEGF, FBS, or FBS+VEGF. Fertilized oocytes were cultured in the same conditions for 8 days. The development of embryos was examined at 48 h post- insemination and on days 6, 7 and 8. The results were analyzed using repeated measures two- factor ANOVA, in which the effects of VEGF and serum were assigned as two factors. The development rate to 4- to 8-cell embryos at 48 h was significantly higher in the PVA+VEGF group than in the PVA group (44.7% and 31.5%, respectively). However, the highest development rate to 4- to 8-cell embryos was obtained from the FBS+VEGF group (58.8%). On day 8, the blastocyst rates were higher in the PVA+VEGF (22.8%), FBS (32.1%, p<0.05) and FBS+VEGF (42.1%, p<0.05) groups than in the PVA group (17.1%). Two- factor ANOVA of the development rates indicates that VEGF had a significant effect, but had no synergistic effect with serum components on early embryonic development. The results of the present study demonstrate that VEGF improves the in vitro developmental competence of bovine oocytes and/or embryos independent of the effect of serum components.

Enforcement Decree of the Framework Act on Low Carbon, Green Growth for achieving the country's GHG emission reduction goal of 30% was in effect. The remarkable content of the Act is the managements of targets for GHG reduction. So, the entities that have reduced voluntarily have much interest in the recognition of 'early action'. The recognition of early action is necessary to induce the fair competence of business entities and promote the voluntary GHG reduction. The definite and concrete guidance should be prepared. The important principles for this are the environmental integrity and the additionality. Based on this, the early action activities must be restricted to the voluntary, real, permanent, quantifiable, verifiable reduction. In the early action recognition, its credit should be allocated additionally set aside from the GHG target allocation in the national total allowance. Through this, the reward for the early reduction should be realized on market mechanism. The effective period to award the early action should be addressed. This can be the period after the enactment of framework on GHG reduction in effect and before the beginning year of GHG target control. It should be set with flexibility through the collection and consultation of the sector's opinions. The appropriate allowance reserve of early action was estimated as approximately 1~1.5% by using the data from the 'Pilot GHG Emission Trading Program' operated by Ministry of Environment. Also, the concrete and detail guidance to construct the necessary infra which is used to register the related information of early action activities should be prepared.

This study was conducted to examine the relationship between pre-service early childhood teacher's motivations of choosing a teaching profession, educational belief, and self-directed learning readiness. The sample included 308 early childhood education major students, and the data were collected using the Modified Orientation to Teach Survey (MOTS), Teaching-belief type scale, and self-directed learning readiness scale. A statistical analysis included correlation analysis and stepwise multiple regression analysis. The results were as follows: 1) analysis of the relationship between pre-service early childhood teacher's motivations of choosing a teaching profession, educational belief, and self-directed learning readiness conveys that intellectual stimulation and self-directed learning had the strongest relationships while nature of work had the weakest. For educational belief and self-directed learning readiness, maturationism and interactionism showed significantly positive correlations while behaviorism displayed a negative correlation. Behaviorism had a significantly negative correlation with openness for challenge, a sub-factor of self-directed learning. 2) Analysis of the effect of pre-service early childhood teacher's motivations of choosing a teaching profession and educational belief on self-directed learning readiness indicates that pre-service early childhood teacher's motivations of choosing a teaching profession had a stronger effect on self-directed learning. These results suggest the following: successful performance as an early childhood teacher not only requires receiving institutionalized education but also self-directed learning while working as an early childhood teacher.

This study is to discuss the effect of the liquid type high early strength agent considering early strength, developing strength, and economics of the concrete using admixtures. The powder type high early strength agent does not helpful because the field application is not available such as the problem of mixing process and rack of economics. To make up these subjects, the plain mixture contains the standard type AE water reducing agent, and the types of the agents are the standard type AE water reducing agent(P),liquid type high early strength agent(AD),poly carboxylate high early strength type AE water reducing agent(E1), and naphthalene + melamine high early strength type AE water reducing agent(E2). As the Contents of the agents, E1 and E2 is two types each cases, and P is one type to satisfy the target fluidity and air content, AD is three types as 0.5, 1.0,and 1.5%. In the case that AD is mixed, the fluidity is decreased, but air content is increased. For increasing strength of the early age, using OPC is more effective than FA and BS for increasing the early strength of the concrete, and if the air content is secure as plain, the effect of the developing strength can be increased because the air content is increased about 2% in the case that AD is used.

The heading date is known to be controlled by two kinds of genetic constituent, photosensitivity and basic vegetable phase. For the latter, the effect of temperature in early growth period is critical to determine the shortness of vegetative growth periods in plant's life. A phytotron experiment on 55 rice cultivars, consisting of two ecotypes of rices, indica and japonica, was conducted at high and low temperature treatments at early growth stage to investigate the possible role of plant growth stimulus by high temperature to associate with shortening of heading date. The high temperature during the early growth stage stimulated the rice growth as measured by plant height with much difference of the growth response between indica and japonica. The conclusive finding that these growth stimulus in early growth stage was highly correlated with the acceleration of heading is, more or less, correlated with the heading of the late growth stage although we could not conclude the genes for early plant growth stimulus by high temperature is the same genes as the genes for accelerating of heading in the late growth stage of plants.
