This paper presents a feasibility study of a fresh air load reduction system by using an underground double floor space. The system was introduced into a real building and was examined by the field measurement. Judging from the measurements during three years(1999~2001), the state of the system operation was very stable through this period and it was clear that the system contributes to reduction of energy consumption for air-conditioning. Futhermore, a simulation model used the simple heat diffusion equation was developed to simulate its thermal characteristics and performances. The simulations resulted in air temperature in good agreement with the measurements. Also, from the result of numerical analysis, it is clear that the amount of heat supply by using this system is more than the amount of energy loss to the room above it. Therefore, it is concluded that this systems is very useful and the proposed numerical model can be used for the prediction of system thermal performance.

This study selected fashion brands claiming to advocate feminism to analyze their characteristics and female images. For the study's data, online foreign feminist fashion brands were sifted from March 2017 to January 2018 and 28 clothing brands were selected. The study's results show that feminist fashion brands aim at the demassification and individualization of fashion products to be more inclusive of individuals' physical characteristics and diversity. Additionally, feminist brands entice consumption through communication and participation in online communities and through the value of social coexistence. The essential female image produced by feminist fashion brands deconstructs a socially idealized female image and expresses a sense of self-body positivity. In turn, the concept of self-body positivity is communicated through natural images of independent women with distinct identities based on differences in race, culture, and sexual orientation. Moreover, feminist fashion brands produce social images featuring independent women using active wear to engage in social activities. Casual wear is also used to reflect active women, while mannish looks and power suits express women's social status and professional abilities. Ultimately, these offer functionally active and rational images, combined with female images featuring long hair and makeup. Yet another type of female image seeks to create a new vision of women as diverse due to their various cultures, countries of origin, races, and individual tastes. These new images express women's physical differences, distinct identities, and diversity while simultaneously deconstructing pre-existing forms of clothing.

The world views the sea newly for the supplementation of the limited land resources and extension of the national territory especially the sea is changing from the period of the free availability to that of the sea control y the coastal nations in step with the announcement of the marine laws in November 16.1994. Therefore Korea is changing strang fisheries nation the fact is that korea cannot effectively cope with changing fisheries situation and various fisheries difficulties because the fisheries policy system is dispersed to each parts of the government. Therefore I tried to present a theoretical basis by studying in the fisheries administration organization. The vision of Ministry of Maritime Affairs and Fisheries is as follow: a coastal fishery must be able to reproduction change of fishery structure must be able to raising fishery consumption of fishery must be able to improvement live of fishing village must be able to betterment overseas fishing grounds must have to security. The results of this study is as follow: fisheries administration organization must be reform of organization for changing under the all situation fisheries administration organization must be reform of entrepreneurial organization fisheries administration organization must be reform of customer driven organization fisheries administration organization must be reform of competitive organization.

The smart city is one of the most promising, prominent, and challenging applications of the Internet of Things (IoT). Smart cities rely on everything connected to each other. This in turn depends heavily on technology. Technology literacy is essential to transform a city into a smart, connected, sustainable, and resilient city where information is not only available but can also be found. The smart city vision combines emerging technologies such as edge computing, blockchain, artificial intelligence, etc. to create a sustainable ecosystem by dramatically reducing latency, bandwidth usage, and power consumption of smart devices running various applications. In this research, we present a comprehensive survey of emerging technologies for a sustainable smart city network. We discuss the requirements and challenges for a sustainable network and the role of heterogeneous integrated technologies in providing smart city solutions. We also discuss different network architectures from a security perspective to create an ecosystem. Finally, we discuss the open issues and challenges of the smart city network and provide suitable recommendations to resolve them.

In recent years, with the rapid growth of China's animation industry, the two-dimensional culture and consumption have been immersed in the daily lives of young people. The two-dimensional culture that mainly exists on young people is gradually entering the public's field of vision, making the two-dimensional culture not It is only restricted to the fixed fan circle, but is known to more people outside the circle. At the same time, the "barrage" (screen text) cultures in video websites has become popular with some film and television works, Internet terms, etc., and has attracted the attention on mainstream culture. On the one hand, its cultural products have appeared on traditional mainstream video websites and advertisements on provincial satellite TV. And in the program, on the other hand, a small part of the screen text and cultural terms are also used by some celebrities and other ordinary people who don't understand the meaning of the terms at all, and have caused widespread dissemination. Sometimes the video website itself is also mentioned, which obviously shows a difference. The tendency towards a kind of screen texts subculture to penetrate the mainstream culture.

This paper deals with research on innovative systems using Python-based artificial intelligence technology in the field of plant growth monitoring. The importance of monitoring and analyzing the health status and growth environment of plants in real time contributes to improving the efficiency and quality of crop production. This paper proposes a method of processing and analyzing plant image data using computer vision and deep learning technologies. The system was implemented using Python language and the main deep learning framework, TensorFlow, PyTorch. A camera system that monitors plants in real time acquires image data and provides it as input to a deep neural network model. This model was used to determine the growth state of plants, the presence of pests, and nutritional status. The proposed system provides users with information on plant state changes in real time by providing monitoring results in the form of visual or notification. In addition, it is also used to predict future growth conditions or anomalies by building data analysis and prediction models based on the collected data. This paper is about the design and implementation of Python-based plant growth monitoring systems, data processing and analysis methods, and is expected to contribute to important research areas for improving plant production efficiency and reducing resource consumption.

The decades after the French Revolution witnessed the prolific production and consumption of apocalyptic literature, tinged with the optimistic vision of political progress and human perfectibility. However, the Romantic writers were cautious to embrace the idea of the end of history, even though it promised an aesthetic space relieved of historical determinants. Mary Shelley's The Last Man joined this line of Romantic literature which skeptically questions the millenarian desires of political apocalypse by representing apocalypse without millenium. Using the theme of apocalypse as a tool to investigate the place of human beings in the universe and to test diverse political reform ideas to their fullest potential, the novel diagnoses the ideas of representative political subject as the most problematic aspect of political structure. The notion of subjecthood presupposes a political decision as to who can be counted as subject and this decision, according to the novel, assumed a subject that is "active, free, conscious and willful sovereign," which Raymond embodies in his exemplary body. Against the sovereignty of Raymond is juxtaposed the subaltern subject such as Sybil. The resistance of Sybil to Apollo, another exemplary subject, is the subtext of the novel, which guides the way out of the grim future of humanity. While the plague exemplifies the universalizing ideal with its principle of sovereignty, Sybil and her descendent Lionel practice the unconditional hospitality so that they can renew the community in a way to embrace singularities of individuals.

Beckett's life-long struggling with death may be illuminated in terms of the Western tradition of thanatology as well as Philippe Ariès's anthropological classification of death. Among the Western tradition, Beckett's oeuvre incarnates memento mori, timor mori, nihilism, theatrum mundi, life as afterlife, and the transsubstantiation of the self. Among the five views of death Ariès suggests, Beckett appears to foreground the death of the self and the invisible dirty death. In a world devoid of transcendental Signified, Beckett's resident is "a poor player/That struts and frets his hour upon the stage." Our contemporary vision of death is dominated by the dirty death and timor mori resurrected from the cultural icon of danse macabre in the late Mediaeval age as vividly dramatized in W;t by Margaret Edson. Beckett stands in no man's land: Lucky complains of divine aphathia as well as scopes at the possibility of God's existence like Hamm. Beckett's way of getting out of the dilemma is laughing a mirthless and dianoetic laugher. To bourgeois class who shudder at the sight of Grim Death after forgettable years of indulgence and addiction to capitalist consumption, Beckett seems to preach, your life is a death-in-life, you are not born yet until you are baptized with existential awakening as Gregor Samsa in Kafka's Verwandlung, or Tolstoy in Confession.
