Abstract: A method for fabricating semiconductor device includes forming an alternating stack that includes a lower multi-layered stack and an upper multi-layered stack by alternately stacking a dielectric layer and a sacrificial layer over a substrate, forming a vertical trench that divides the upper multi-layered stack into dummy stacks, and forming an asymmetric stepped trench that is extended downward from the vertical trench to divide the lower multi-layered stack into a pad stack and a dummy pad stack, wherein forming the asymmetric stepped trench includes forming a first stepped sidewall that is defined at an edge of the pad stack, and forming a second stepped sidewall that is defined at an edge of the dummy pad stack and occupies less area than the first stepped sidewall.

Abstract: An artificial skin culture container according to the present invention can solve the problems of the contraction of the dermal layer of artificial skin and the detachment thereof from the culture container, which result from an interaction between collagen and fibroblasts existing in the dermal layer of artificial skin during the production of the artificial skin, by using agar and hydrophobically modifying a portion of the agar. Therefore, the use of the culture container enables to stably culture artificial skin and produce artificial skin similar to the human skin. In addition, the artificial skin culture container of the present invention comprises agar, and thus a culture solution can be supplied through a side portion as well as a lower portion of the culture container, which allows to effectively culture artificial skin.

Abstract: The present disclosure relates to a hydraulic circuit system for forced regeneration of a diesel particulate filter, and more particularly, to a hydraulic circuit system for forced regeneration of a diesel particulate filter (DPF), which prevents a working machine from being operated when the diesel particulate filter is forcedly regenerated by combusting particulate matters (PM) in a case in which the diesel particulate filter is installed in a construction machine with a diesel engine and particulate matters contained in exhaust gas are collected in the diesel particulate filter.

Abstract: The present invention relates to a non-invasive prenatal testing method and, more particularly, to a method for enhancing the sensitivity and accuracy of non-invasive prenatal testing by applying multi-dimensional threshold values based on multiple Z-scores. Designed to reduce false-positive and false-negative possibility by applying two or more Z-score threshold values to aneuploidy detection for one chromosome, the non-invasive prenatal testing method according to the present invention exhibits the effect of obtaining a more sensitive and more accurate test result. Further, the method can minimize test errors in spite of using a small number of nucleotide sequence fragments, with the resultant effect of reducing an experiment cost and thus expensive testing cost and rapidly performing testing with a low expense.

Abstract: The present disclosure discloses a method for improving the skin condition or anti-microorganisms or anti-oxidation using Lactobacillus sakei MD_honeysuckle (accession number: KCTC 12675BP) derived from Lonicera japonica Thunb.

Abstract: A polyurethane filter foam is provided herein. The polyurethane filter foam may have improved permeability by having both a small cell and a large cell in a range for maximizing the opening property of the foam. In some instance, this is achieved by specifically configuring and foaming a composition of polyether polyol and methylene diphenyl diisocyanate (MDI) to manufacture the polyurethane foam. The polyurethane foam of the present invention can be manufactured without performing a reticulation process.

Abstract: A fuel cell separator, a fuel cell stack having the fuel cell separator, and a reactant gas control method of the fuel cell stack are provided. That is, even when the fuel cell stack operates under the low load operation condition, a reactant gas is supplied to the reactant gas passages of the fuel cell separator, and thus, the length of the passage can be shortened by 50% as compared with the prior art having only one reactant gas passage. Therefore, the reactant gas can be effectively supplied without experiencing pressure loss. Further, in the high load operation of the fuel cell stack, the reactant gas is introduced into the first reactant gas passage of the fuel cell separator and utilized in half of the whole electrode area. Subsequently, the reactant gas is introduced into the second reactant gas passage and utilized in the remaining half of the electrode area.
