A zoom lens and a photographing device including the zoom lens, the zoom lens including a first lens group having a negative refractive power, a second lens group having a positive refractive power, and a third lens group having a positive refractive power, which are sequentially arranged in the direction from an object side to an image side. During zooming from a wide angle position to a telephoto position, an interval between the first lens group and the second lens group decreases, and an interval between the second lens group and the third lens group increases. The first lens group comprises a first lens, a second lens being a negative lens formed of plastic, and a third lens being a positive lens formed of plastic. Therefore, the zoom lens is compact and low-priced and has a high magnification.

Disclosed is a method of preparing high crystalline nanoporous titanium dioxide, in which the high crystalline nanoporous titanium dioxide, which is harmless to the human body and self-purified through the decomposition of organic matters, is prepared in mass production at the room temperature through a simply synthesis method. The method includes the steps of (a) mixing a titanium precursor and a surfactant in a solvent and performing a sol-gel reaction at a room temperature; (b) maturing a reactant obtained through the sol-gel reaction at the room temperature; (c) filtering the matured reactant and washing the matured reactant; and (d) drying the washed reactant to obtain titanium dioxide having nanopores.

The present invention provides electric pruning shears which can improve operation convenience by increasing the operating speed and eliminating hand fatigue during pruning of fruit trees.For this purpose, the present invention provides electric pruning shears which can improve safety during handling by implementing a new type of switching means having a separate safety switch capable of being separated from a main body and put on a user's finger and reduce the volume and weight by reducing the number of parts associated with the safety switch. Moreover, the present invention provides electric pruning shears which control a motor to be reversely rotated when there is an abnormality in blades of the electric pruning shears during a pruning operation, thus escaping from the overall abnormality including motor damage.
