The purpose of this study is to analyze the spatial structure of director Im Kwon-taek's film , which was released in 1997. The space of the film contains the character and characteristics of the characters, and allows us to understand the contemporary reality and external circumstances surrounding the characters. For this purpose, this study used Michel Foucault's concept of heterotopia. The concept of heterotopia defines the character of the era and provides implications for how capital, power, institutions and norms surrounding our lives are being visualized through space. Based on this understanding, this study first dealt with the theoretical considerations of Michel Foucault's concept of heterotopia and its meaning. And through this, we investigated the possibility that the space of the film can be defined as a heterotopia. Through the analysis of the film's dialogue, scenes, and editing, the space of the film was divided into a heterotopia of deviation, a heterotopia of resistance impossibility, and a heterotopia of boundaries. The meaning of the film obtained through this analysis is as follows. The woman in the film is passively represented and floating on the border of heterotopia. And the film represent history and memory at the same time, and presents a heterotopia as the arena of competition.

In the 1970s, the full-scale development of the area now known as Gangnam began, ushering in the era of real estate investment on apartments which transformed housing styles in Korea. Apartments were pitched as the most ideal type of housing, creating a competitive market of high demand and skyrocketing prices. The apartments were also viewed as a means of quick asset investment among middle-class Koreans. Within this apartment frenzy stood the female real estate speculator, the bokbuin. This study seeks to locate the bokbuin in the real estate development market after the late 1970s. The apartment speculation boom cannot be attributed to the bokbuin alone, yet she became the target of public anger and criticism, singled-out as being responsible for fueling illegal and unethical investments. The apartment boom of the 1970s was in fact generated in large part by the government, developers, construction companies and realtors. While their pursuit of profit was deemed as legitimate, the bokbuin's conduct was mostly tainted by presumed illegitimate and greedy motivations. This study problematizes this gendering of real estate investment and treat the bokbuin as a byproduct of the family-centered culture in East Asia. Analyzing Im Kwon Taek's film "Mrs. Speculator", Park Ki Won's conte, "Bokbuin", Park Wan Seo's short story, "Children of Paradise", "The People of Seoul", this study shows that bokbuin's pursuit was not hers alone; it was the collective pursuit with her husband for the enhancement of family finances. This stud y argue that the bokbuin embodied the thickly misogynistic climate of the 1970s that projected the chaotic rise of greed onto the woman.

Aiming the development of novel acid amplifiers, 2-hydroxyphenyl-4-methylbenzenesulfonate (1), 3-hydroxyphenyl-4-methylbenzene sulfonate (2), 4-hydroxyphenyl-4-methylbenzenesulfonate (3) were synthesized as the aromatic acid amplifiers with good thermal stability. They were autocatalytically generated p-toluenesulfonic acid in the presence of small amount of acid evolved from a photoacid generator. These aromatic sulfonates showed excellent thermal stability in PtBMA film and were proven to be the first aromatic acid amplifier to act as a photosensitivity enhancer. When these compounds were coupled with a chemically amplified photoresist system, photosensitivity was enhanced up to 3~6 folds.

Poly($\small{L}$-Lactide)(PLLA) was prepared by a ring-opening polymerization of $\small{L}$-Lactide with various polydimethylsiloxane(PDMS) based copolymers as a stabilizer in supercritical carbon dioxide($scCO_2$). The block copolymeric stabilizers were synthesized by group transfer polymerization (GTP) by using PDMS macroinitiator. PLLA was found to be produced with fairly low molecular weight distribution as confirmed by gel permeation chromatography(GPC) analysis. Scanning electron microscopy (SEM) results showed that sub-micron size Poly($\small{L}$-lactide)(PLLA) particles were formed by suspension polymerization.

The objectives of color reproduction in printing, photography, and digital hard-copy is an important problem. The Color is obsorved differently from illumination an obsorvation condition, and varied according to individual taste. Generally, the color reproduction system is designed with colorimetric color reproduction method. But the color gamut of the color reproduction system is different each other and the one device has nonlinear relationalship between the other. By these reason, to predict the reproduced color based on linear color transform method is difficult. Some methods of non-linear color transform by neural network was proposed. These method was theoretical useful and valid to transform from CIE color to device color. But more studies were needed to realize the non-linear color transform system. In this paper, we described a method to realize the non-linear color transform system by neural network. The optimum structure of the non-linear color transform system was found out. The structure of descrived system has four layer( input, output and two hidden layers.) Input and output layer have 3 units, and a hidden layer has 27 units. We trained 216 color-samples, and estimated the realized color transform system by 1115 color-samples. The average color difference between original color samples and transformed color samples was 2.54.

Chemically amplified deep UV(CA-DUV) resists are typically based on a combination of an acid labile polymer and a photoacid generator(PAG) but acid amplification type photoresist is formulated by addition of the acid amplifiers to chemically amplified resist system(CAPs). We developed acid amplifiers base on cyclohexanediol such as 1-methacryloyloxy-4-tosyloxy cyclohexane(MTC) and poly(MTC$_{10}$-co-tBMA$_{90}$)(P-1) to enhance photosensitivity. P-1 is a copolymer of tert-butyl methacrylate and MTC as a positive working photoresist based on polymeric acid amplifier in order to enhance photosensitivity and simplify the process of fomulating a photoresist. P-1 exhibited 2X higher photosensitivity compared with PtBMA. The acid amplifiers showed reasonable thermal stability for resist processing temperature and higher photosensitivity compared with chemically amplified resist.

Acid amplifying copolymers are synthesized by the copolymerization of tert-butyl methacrylate(tBMA) with acid-sensitive functional group and 4-hydroxy-4'p-styrenesufonyloxyisopropylidene dicyclohexane(HSI) or 4-p-styrenesulfonyloxy-4'-tosyloxyisopropylidenedicyclohexane(STI) with acid-amplifying group as novel polymeric acid amplifying photoresists. Poly(HSI-co-tBMA) film and Poly(STI-co-tBMA) film as acid amplifying photoresists show reasonable thermal stability in the absence of an acid species. Poly(STI-co-tBMA) film exhibits 2X higher photosensitivity, whereas Poly(HSI-co-tBMA) film show 2X lower photosensitivity compared with ptBMA homopolymer. The attachment of acid-amplifying units to polymer backbones could provide a novel way to enhance the photosensitivity of acid-sensitive polymers depending on the structure of acid-amplifying units.
