There are long land border lines and many developable passes. Under the direction of total national development strategy of coastal and border opening, considering the advanced condition of location,the new spatial frontier trade pattern of 'multilevel and all-round position' has initially been formed.That is,to develop westwards market in Middle Asia,to enlarge southwards market in Pakistan and to open up northwards market in Mongolia.The great progress of border opening has been made in Xinjiang.At present, Xinjiang is catching the opportunity to adjust the industrial structure and regional allocation,enhance horizontal economic combination and cooperation,and strengthen the infrastructures construction.Therefore more solid material foundation ofborder opening will be formed for further enlarging.展开更多

Firstly Mr. Jiang made a briefintroduction on Shaanxi. Shaanxi, located atthe junction of the middle and western areasof China, is one of the origins of China’ssplendid ancient civilization. Its rich mineralresources include 92 varieties of provenreserves, 28 of which, including molybdenum,rhenium, mercury, coal and natural gas havereserves ranking in the first three and 58ranking in the top ten in the country.展开更多

Quantifying prefrontal cortex activity during resting states provides a baseline for interpreting task-induced brain activity. Researchers commonly use resting conditions where participants are prompted to stare at a screen (eyes open) or close their eyes (eyes closed). Are these two conditions equivalent representations of a baseline resting state? Further, does prefrontal cortex activity during these conditions change as a function of development? The aim of this study was to examine differences in prefrontal cortex activity between eyes open and eyes closed conditions during resting states in children and adults to provide a rationale of proper selection of baseline condition in future research. Thirty-six participants in 3 age groups were recruited in this study including twenty-four adults, five 12 - 15 years old children, and seven 8 - 11 years old children. Relative changes in concentrations of oxygenated hemoglobin (Δoxy-Hb) and deoxygenated hemoglobin (Δdeoxy-Hb) were obtained by using functional Near-Infrared Spectroscopy (fNIRS) in eyes closed (EC) and eyes open (EO) conditions, 3 minutes each. Contrasts were tested to compare the differences of Δoxy-Hb and Δdeoxy-Hb between eyes open and eyes closed conditions. The EC condition had significantly higher Δoxy-Hb than EO when all groups were combined (t (17.268) = 3.021, p = .008, Cohen’s d = –0.72). When comparing Δoxy-Hb between eyes conditions within each group, the younger group had significantly higher Δoxy-Hb in EC than EO (t (9.459) = 2.734, p = 0.022, Cohen’s d = –1.46). Based on these results, the EO condition may be a better baseline condition, particularly in studies with younger children, since it has less activity in the PFC that could interfere with interpretations of task-induced activity.展开更多
