The purpose of this study is to examine the medicalizing process of menopanse with literature review, and then is to explore the knowledge of 'menopausal syndrome' critically, focused on four critics on the biomedical model which were suggested by Mishler. Although menopause is a natural biological phenomenon, the view of many medical researchers and practitioners is that menopause is a disease. After synthetic estrogen was developel in 1938, physicians did agree on two basic assumptions : menopausal women should be managed by physicians, and medical intervention should be given. Menopouse was defined as a deficiency disease (estrogen difficiency) by Wilson in 60's and is redefined as a cause of disease(for example, osteoporosis, heart disease) at the present. But the other view of non-medical researcher is that 'menopausal syndrome' as a disease is constructed medically. It was reported that Only hot flush and sweating of physical symptoms experienced by menopausal women, were associated with menopause. Symptoms of menopausal syndrome are also related with symptons of aging. So, it cann't conclude that menopausal syndrome is resulted from menopause, and it cann't be only explained that menopausal syndrome is related causally to estrogen deficiency, and only treatment by ERT or HRT is best relevant. It cann't assume that menopausal syndrome is a common phenomenon to all menopause women, because culture affected on women's experience of menopause.

This study examines the space composition and character of German Modern Theater barre on the theory of typology and interpreter in the european traditional classic theater. Contemporary multi purpose theater and public space is considered as a symbolic representation of the classic theater's organization. In the historical theory, modern theater was a common tool and best systeme in reflecting people's lives. This role of greece-roman theater as life cycle and new style of theater permanent design has get its value with the population increase and the urban centralization of the city and urban common sense. This study attempts to reevaluate the need of space typology in modern society through a critical review of theater and its use as a open space design. Content analysis was used to discuss the topics of this study including the historical background of the theater, the relationship between amphitheater and modern theater design, and the role of scenery, auditorium and its impact on urban environment. The scope of the study is limited to the comparison of classic theater and german modern theater space use program from the space critic and sociologist. Today the concept of theatrical space is altered with the typology of classic and interpreter space. This study provides insights for the future implications of theatrical space in developing public space for its a new definition as cultural representation.

One of the most notable architectural aphorisms in modern period must be undeniably Louis Sullivan's, 'Form Follows Function.' The aphorism has been not only an important source of new aesthetic but also an formal principle of machine age. Other most famous source in order to justify modern aesthetic was the short essay by an cynical critic, Adolf Loos(1870-1933), 'Ornament and Crime' of 1908. Apart from what the essay asserted it is also famous for the influence of Sullivan's architectural notion during Loos' States staying. For Architectural historians of the early 20th century this connection is so useful to create a legacy of modern architecture. The historians seemed to believe that Loos understanded Sullivan's aphorism on which the historians wanted to focused. When we however look into two buildings designed and built in the period of publishing both aphorism and essay there must be a big fissure between the buildings and the historians interpretations. With this view point this study aims at showing the true meanings of Sullivan's aphorism and Loos' essay and also the big difference between the machine age's aesthetic and theirs.

This study examines the space composition and character of 16th Renaissance Theater base on the theory of typology and interpreter in the european traditional classic theater. Baroque theater and early modern theater is considered as a symbolic representation of the renaissance theater's organization. In the historical theory, theater Teatro Olimpico and Teatro Farnese was a common tool and best systeme in reflecting renaissance type and perspective system. This role of type as life cycle and new style of theater permanent design has get its value with the population increase. This study attempts to revaluate the need of space typology in modern society through a critical review of theater and its use as a visual space. Content analysis was used to discuss the topics of this study including the historical background of the theater, the relationship between amphitheater and modern theater design, and the role of scenery, auditorium and its impact on Proscenium scenery. The scope of the study is limited to the comparison of 16th european theater and contemporary theater space use program from the space critic and sociologist. Today the concept of theatrical space is altered with the typology of classic and interpreter space. This study provides insights for the future implications of theatrical space in developing space for its a new definition as cultural representation.

This paper proposes a novel fault tolerant tracking control (FTTC) scheme for a class of nonlinear systems with actuator failures based on the policy iteration (PI) algorithm and the adaptive fault observer. The estimated actuator failure from an adaptive fault observer is utilized to construct an improved performance index function that reflects the failure, regulation and control simultaneously. With the help of the proper performance index function, the FTTC problem can be transformed into an optimal control problem. The fault tolerant tracking controller is composed of the desired controller and the approximated optimal feedback one. The desired controller is developed to maintain the desired tracking performance at the steady-state, and the approximated optimal feedback controller is designed to stabilize the tracking error dynamics in an optimal manner. By establishing a critic neural network, the PI algorithm is utilized to solve the Hamilton-Jacobi-Bellman equation, and then the approximated optimal feedback controller can be derived. Based on Lyapunov technique, the uniform ultimate boundedness of the closed-loop system is proven. The proposed FTTC scheme is applied to reconfigurable manipulators with two degree of freedoms in order to test the effectiveness via numerical simulation.

In this paper, we propose a time-varying proportional navigation guidance law that determines the proportional navigation gain in real-time according to the operating situation. When intercepting a target, an unidentified evasion strategy causes a loss of optimality. To compensate for this problem, proper proportional navigation gain is derived at every time step by solving an optimal control problem with the inferred evader's strategy. Recently, deep reinforcement learning algorithms are introduced to deal with complex optimal control problem efficiently. We adapt the actor-critic method to build a proportional navigation gain network and the network is trained by the Proximal Policy Optimization(PPO) algorithm to learn an evasion strategy of the target. Numerical experiments show the effectiveness and optimality of the proposed method.

The existing underwater vehicle controller design is applied by linearizing the nonlinear dynamics model to a specific motion section. Since the linear controller has unstable control performance in a transient state, various studies have been conducted to overcome this problem. Recently, there have been studies to improve the control performance in the transient state by using reinforcement learning. Reinforcement learning can be largely divided into value-based reinforcement learning and policy-based reinforcement learning. In this paper, we propose the roll controller of underwater vehicle based on Deep Deterministic Policy Gradient(DDPG) that learns the control policy and can show stable control performance in various situations and environments. The performance of the proposed DDPG based roll controller was verified through simulation and compared with the existing PID and DQN with Normalized Advantage Functions based roll controllers.

This article studies that Korean literature has been renewed to World literature-oriented in the history of Modern Korean literary criticism from early modern period to present for reflecting the slogan, "globalization of Korean Literature" as well as contextualizing the necessity, "new relationship between Korean literature and World literature". Some writers, such as Lee Gwangsoo a pioneer of Modern Korean literature and the group for foreign literature[haioei-munhak-pa] introducing World literature to Korea and Lim hwa a prominent critic of proletarian literary theory under Japanese Colonial period, have understood European literature as World literature Korean literature had to reach. Inevitably the hierarchical relation between Korean literature and European literature as World literature had been interiorized to them. Meanwhile Jo Dong-il and Paik Nak-chung who have been representative researchers of Korean literature had tried to broken down the hierarchical relation between Korean literature and European literature interiorized to Korean writers until the 1980s, with Korean literature could be accomplished to World literature meaning. Since the late 1990s Park Sung-chang and Park Sang-jin who are leading researchers of comparative literature in Korea these days, have emphasized the methodology of new comparative literature for 'universality of literature' between Korean literature and World literature, which have been the renewal way of Korean literature in today's age of globalization.

The Queen of the Air, John Ruskin-s highly elliptical publication of 1869, elaborates a complex mythology as a way of responding to the prevalence of scientific thinking, widespread environmental degradation, the pernicious effects of political economy, and mechanistic labor. Benjamin-s desire to rescue human experience from prevailing scientific conceptions is reminiscent of Ruskin-s fear that the peculiar power that shapes the unities of the natural world is simultaneously being "beaten down by the philosophers into a metal or evolved by them into a gas" and obscured by the dreams and theories of philosophers and theologians. As a critic remarks, in Benjamin-s-and, we would add, Ruskin-s-view, "what the modern era lacked was a basis for continuity which would prevent experience from disintegrating into a desultory and meaningless series of events." Despite its frenetic hyper-associativity, then, The Queen of the Air contains a key element that Benjamin believes is necessary for "redemption": the desire for a new form of consciousness that recognizes links to the past and thus to the longings and dreams of our forebears. Thus, although Ruskin most immediately influences Proust, who in turn influences Benjamin, Benjamin-s thought is far more Ruskinian than critics have heretofore observed. Just as Benjamin helps us make sense of the ways in which The Queen of the Air is caught in the grip of the shocking associativity of modern life, so Ruskin assists us in discerning similar impulses in Benjamin-s attraction to a form of archaic consciousness that can, by altering the modern form of perception, reenchant the present.

This paper explores how gender, sexuality, momism and national security are intertwined in the POW fictions of the Korean War, revealing the blurred demarcation line of the private and the public during the Cold War era. Works such as Night and Valley of Fire reveal the weakened manhood of the soldiers who were brainwashed or easily succumbed to the enemy during their imprisonment. The novels commonly attribute their weakness to materialism and spiritual corruption prevalent in the society, in addition to mass media including TV. Moreover, a social critic like Phillip Wily provokes the polemical idea of "Momism" which was ardently circulated among some male circles. In Manchurian Candidate, momism is integrated into incest and homosexuality, epitomized by Raymond and his mother. The novel illustrates how momism can be dangerous to national security and devastate the growth of manhood. Mrs. Iselin, a masculinized middle-aged woman, becomes a 'monster' whose overweening desire for power overrides any maternal concern for her son. Such 'monstrosity' exposes the danger of a woman who can castrate a man and manipulate a society. To a certain extent, the same tendency can be found in Turncoat and Night. Both novels reveal how the love of mother brings detrimental impact on boys who become prey to the communist's brainwashing in the POW camps. In short, the POW novels betray society's patriarchal concerns with women's emerging power threatening its ideology.
