  • This paper describes to the unit rectangle EB direct writing lithography method using SEM. This method has the constant exposure time to any rectangle pattern. In order to change the EB current according to various rectangle size for the constant exposure time, the supply current of condenser lens in controlled by BITMAP-IV CAD system. By this method, the resizing procedure of density pattern area is not needed to pattern data conversion, and the through-put ofr exposure is increased about 172 times compared with the unit scan exposure method.

  • 355nm UV pulse laser is irradiated on the surface of polyimide (PI) by LDW (Laser Direct Writing) method to produce a high sensitivity flexible humidity sensor using a simple one-step process. The LDW method continuously investigates 2-D CAD data using a galvano scanner and an F-lens. This method is non-contact, so it minimizes physical strain on the PI. Laser-induced graphene (LIG) produced by lasers has a high surface area due to its high flexibility and numerous pores and oxidizers compared to conductors. For this reason, it is highly useful as a flexible humidity sensor. The humidity sensor produced in this study was attached to the inside of a mask filter, which has become a hot topic recently, and its applicability was confirmed.The measurement of humidity measured the sensitivity, reactivity, stability and recovery behavior of the sensor by measuring changes in capacitance and resistance.

  • This paper examines narratives of women's marginal position in Bao Ninh's Short Stories and Svetlana Alexievich's Unwomanly Face of War from a feminist narratological approach. In analyzing voices of marginalized women, direct and indirect descriptions of women's beauty and pain, and private-public narratives of women's love stories, this paper aims to identify presentations of women's real authority in the text written by a male author, Bao Ninh, and in the one by a female author. The paper argues that juxtaposing these texts reveals an overturn of the traditional conception of sexual and gender differences. Specifically, distinguishing between male/female discourse does not show powerful /nonpowerful language, but recognizes the real authority of each type of discourse based on sexual differences. The writing also illustrates that masculine language becomes powerless and deficient in the women's world; meanwhile, in writing about herself, woman establishes a type of a powerful feminine discourse, which blends both emotional, enthusiastic, and gossipy characteristics of female language and direct, rational, and strong ones of male language. Thus, the feminists' radical segregation on male/female discourses to overturn masculine authority and create a language for women at par with men has been clearly shifted when comparing the two writers' texts based on the juxtapositional model of the comparative literature.
