드랙 퀸(Drag Queen)과 드랙 킹(Drag King) 패션에 관한 연구
정세희(Se Hui Chung),양숙희(Sook Hi Yang) 한국복식학회 2004 服飾 Vol.54 No.7
The purpose of this research was intended to investigate drag queens` and drag kings` gender identity not only as a comic and desexualized drag borrowing external characteristics of the opposite sex but also as the subject visualizing and performing `the third sex`. It also aimed to examine formative aesthetic characteristics and aesthetical value of drag queen`s and drag king`s fashion and to confirm the functions of drag queen`s and drag king`s fashion to establish, visualize and perform the discordant sex. For this process, research steps were as follows 1. Understanding drag, drag queen and drag king in social, psychological context as well as in gender context. 2. Finding visualized forms which drag performance interchange with mass media 3. Analyzing similarities and differences between drag queen`s fashion and drag king`s fashion. 4. Examining the aesthetical characteristics and the value of drag queen`s and drag king`s fashion. The results of characteristics of drag queen`s fashion could be categorized into stereotype, mimicry, kitch, inconsistency and commercialism. And the characteristics of drag king`s fashion could be divided into reality. self-consciousness, mimicry, inconsistency, subversion and multiplicity. Drag queens create plausible impressions of feminity through the use of wigs, dresses, jewelry, makeup, hormones and through role playing. Similarly drag kings produce a plausible masculinity taking gay male aesthetic using suits, crotch stuffers, facial hair, and greased hair. Male and female impersonation produce very different notions of gender performance for male and female embodiment. Drag kings` performance of masculinity demands authentic property of bodies so rather nonperformative, while drag queens` performance of femininity depends on more visible and theatrical fashion.

The cryogenic fracture behaviors of austenitic stainless steel HN2 developed for nuclear fusion reactor were evaluated quantitatively by using the small punch(SP) test. The electrochemical polarization test was applied to study thermal aging degradation of HN2 steel. The X-ray diffraction(XRD) analysis was conducted to detect carbides and nitrides precipitated on the grain boundary of the heat treated HN2 steel. The mechanical properties of the HN2 steel significantly decreased with increasing time and temperature of heat treatment or with decreasing testing temperature. The integrated charge(Q) obtained from electrochemical polarization test showed a good correlation with the SP energy(ESP) obtained by means of SP tests. From the results observed in the x-ray diffraction and anodic polarization curve, it was known that the material the grain boundary. Combining SP test and electrochemical polarization test, it could be useful tools to non-destructively evaluate the cryogenic fracture behaviors and the aging degradation for cryogenic structural material.

This paper was undertaken to develop the fracture toughness testing method using small and single specimen compared to the conventional method in evaluating elastic-plastic fracture toughness of the superconducting magnet structural material at cryogenic temperature. The elastic-plastic fracture toughness test was conducted by using the unloading compliance method recommended by ASTM E813-89 to accomplish the above purpose. And, the 20% side-grooved 0.5TCT and 1TCT specimens were used to evaluate the fracture toughness by using as possible as miniaturized CT specimen. The unloading compliance method was a very useful method in evaluating elastic-plastic fracture toughness at cryogenic temperature. It could be taken valid fracture toughness values by using 20% side-grooved 0.5TCT specimen recommended by ASTM E813-89.

A traditional notion of composites has been composed as a uniform dispersoid, but now it is proposed without regard to such rule with process development. Functionally Graded Material(FGM) consists of a new material design that is to make intentionally irregular dispersion state. In this study, thermal stress analysis of plasma spraying PSZ/NiCrAlY gradient material was conducted theoretically using a finite-element program. A formations of the model are direct bonding material(NFGM) and FGM with PSZ and NiCrAlY component element. The temperature conditions were $700^{\circ}C$ to 1100.deg. C assuming a cooling-down precess up to room temperature. Fracture damage mechanism was analyzed by the parameters of residual stress.

The grain boundary etching method as a method for assessing degradation of structural materials has received much attention because it is simple, inexpensive and easy to apply to real components. In this study, the effectiveness of the method is verified by successfully applying the technique to in-service components of aged fossil power plants such as main steam pipes, boiler headers an turbine rotors. A new degradation parameter, intersecting number ratio (N$_{1}$/N$_{0}$), is employed. The intersecting number ratio (N$_{1}$/N$_{0}$) is defined as the ratio of intersection number (N$_{1}$) obtained from 5-minute picric acid etched surface to the number (N$_{0}$) obtained from nital etched surface. Two kinds of test materials, 2.25Cr-1Mo steel and 1Cr-1Mo-0.25V steel, were artificially thermal-aged at 630.deg. C in different levels of degradation., (N$_{1}$/N$_{0}$) were measured. And, correlations between the measured values and LMP values calculated from aging temperature and aging time were sought. To check the validity of the correlations obtained in laboratory, similar data were measured from service components in four old Korean fossil power plants. These on-site measurement data were in good correlation with those obtained in the laboratory.oratory.

The hot press apparatus to obtain the solidified rocks with 60mm of diameter against rock waste was developed, and the optimum conditions for solidification were founded out, of which were 300.deg. C of temperature and 1hr of holding time. The solidified rocks reinforced with the fibers (carbon, steel) were made by means of a hydrothermal hot press method. Fracture toughness of those was obtained using the round compact tension(RCT) specimens. Load and displacement behaviours of the solidified rocks reinforced with the fibers were dependent upon the fiber volume fraction and kind of the fibers. Strength and fracture energy of the solidified rocks with steel were much larger than those of the solidified ones with carbon because of the Bridge's effect, multiple cracking and crack branching phenomena.
