  • 최근들어 화석 연료의 고갈, 지구 온난화등의 문제들로 인해, 녹색성장 기술이 중요시 되고 있다. 에너지 문제와 녹색성장 기술이 융합된 신성장동력 확보를 위해 풍력, 태양광, 연료전지, 바이오 연료등에 많이 투자가 확대되고 있다. 그 중 풍력발전은 다른 에너지에 비해 경제성이 높고, 유해물질의 배출이 거의 없다. 따라서 최근 정부나 기업들에서도 많은 비용을 투자하여 풍력 기술 개발에 적극적인 지원을 하고 있지만, 풍력 기술을 선도하는 해외 선진국들에 비해서 국내에서의 관련 교육과 장비는 연구소 수준에 머물고 있다. 그러므로 관련 산업에서 요구하는 기본 기술의 저변화와 기술적 향상을 위해 실제 산업에서 적용하고 있는 시스템과 유사한 자비와 교육과정의 개발이 필요한 실정이다. 본 논문에서는 실험을 통하여 풍력터빈제어의 이론적인 내용을 수강생들이 보다 쉽게 이해할 수 있도록 교육용 풍력터빈제어 실습장치를 개발하고 교육효과를 알아보았다. 개발된 실습장치를 소개하고, 각각의 실습장치를 소개한다. 마지막으로 설문조사를 통하여 반응도 평가를 통한 교육효과를 검증하였다.

  • Contemporary society is lately going through various changes in social, economic, and cultural aspects due to rapid growth of information and computer technology. The digital revolution generated from the development of network reflects the decentralizing characteristic that connects local and personal interconnections. The following paper is designed to develop a basic understanding of digital architecture and show that digital virtual reality is not accidental phenomenon but it is actually evolved from nature and recreated in cyber space. The relationship between nature and digital architecture will be explained through the background research of how digital architecture was born and how it has been transformed. Also, it is designed to find out modern trends of digital architecture through diagrams and virtual space of hyper architecture and follow up the new phenomena appearing in the field of architecture. It is said that digital architecture is a new trend of architecture created from computer bit but all architecture that has form and shape cannot be independent of nature. Nature is the root of everything and even mechanical abstraction such as 'digital' can find its form in the immanence melted in the pure essence of nature. The research found that the nature approach of digital architecture also needs no more than 5 sequential references to find its genuine sketch as the hypertext theory shows we need only 5 sequential references to prove we are all related. Additionally, the cyber space that is become a general living space and a indispensable factor of digital architecture is a space that has obscurity and more open culture. It represents the characteristics of contemporaries in various aspects of society.

  • 우리나라는 경제 사회적 구조 변화로 인해 재난에 취약한 계층이 증가하고 있다. 특히, 고령화, 양극화, 국제화 추세가 심화됨에 따라 노인, 장애인, 기초생활수급자, 외국인, 다문화 가정 등 사회적 취약계층으로 불리는 이들이 재난에도 취약한데 흔히, '재난약자'라고 불린다. 재난약자들은 재난 발생시에 일반인과 달리 재난정보 획득에 어려움을 겪는 등, 자력으로 신속한 대응이 어렵기 때문에 특별한 관심과 관련된 정책이 필요하다. 물론, 최근에 재난약자에 대한 연구가 꾸준히 증가하고 있지만 외국인에 대한 논의는 상대적으로 부족하고, 이는 그들에 대한 재난에 대한 이해나 대처방법에 대한 실태를 정확하게 파악하지 못하게 되어 한국인의 시각과 관점에서 관련 정책을 마련하게 되고, 결국 국내 체류 외국인들은 관련 정보를 얻는데 어려움을 겪을 수 밖에 없는 악순환이 반복되고 있다. 이에 본 연구에서는 국내에 거주하고 있는 외국인 근로자를 대상으로 재난정보에 대한 인식과 획득경로 등에 대한 심층인터뷰를 실시하였다. 인터뷰를 통해 도출된 결과를 바탕으로 국내 체류 외국인 근로자들이 빈번하게 접하는 정보매체를 이해하고, 적극적으로 활용하는 방안 등 실질적인 정보제공을 위한 함의를 도출하였다.

  • This essay examines Edward Said's Culture and Imperialism focusing on the concepts of 'culture,' 'empire,' and 'nation'. The approach is critical, theoretical, and historical rather than explicatory. Consequently, the range of the essay is not limited to Said's own explanation and argument about Western imperialism and its culture presented in the book. In doing this, this essay finally purposes to be a discursive resistance to the current global empire, the United States, via a critical reading of Said's work. Said's notion of culture is set upon to disclose the function of culture as an apparatus of ideological consent of the dominated to the dominant. When applied to imperial practice, Western culture functions to subject the colonized to the colonizer. Said's geographical approach to imperialism complements the historical understanding of imperialism. Imperialism is not only the practice of Western-centered historicism but also the spatially mutual interaction between the West and the rest of the world. Along with European imperialism, Said poses the current global empire of the United States as his main target of criticism. Said's problem is that he takes the United States as a nation-state. When examined, the United States is not a nation-state, but today's empire. The empire in the appearance of the nation-state United States does not work for the interest of the American nation, that is, the American people. The empire is the transnational and postnational political and economic institution that works for the interest of global capital. In order to resist the current global empire, this essay suggests that the building or restoration of nation-states with its basic principle of people's sovereignty is in need.

  • Purpose: The aim of this study was to identify core keywords and topic groups in the "adolescent pregnancy" field of research for a better understanding of research trends in the past 10 years. Methods: Topics related to adolescent pregnancy were extracted from 3,819 articles that were published in journals between January 2013 and July 2023. Abstracts were retrieved from five databases (MEDLINE, CINAHL, Embase, RISS, and KISS). Keywords were extracted from the abstracts and cleaned using semantic morphemes. Text network analysis and topic modeling were performed using NetMiner 4.3.3. Results: The most important keywords were "health," "woman," "risk," "group," "girl," "school," "service," "family," "program," and "contraception." Five topic groups were identified through topic modeling. Through the topic modeling analysis, five themes were derived: "health service," "community program for school girls," "risks for adult women," "relationship risks," and "sexual contraceptive knowledge." Conclusion: This study utilized text network analysis and topic modeling to analyze keywords from abstracts of research conducted over the past decade on adolescent pregnancy. Given that adolescent pregnancy leads to physical, mental, social, and economic issues, it is imperative to provide integrated intervention programs, including prenatal/postnatal care, psychological services, proper contraception methods, and sex education, through school and community partnerships, as well as related research studies. Nurses can play a vital role by actively engaging in prevention efforts and directly supporting and educating socially disadvantaged adolescent mothers, which could significantly contribute to improving their quality of life.

  • Recently, intensive research has been conducted to develop innovative methods for diagnosing plant diseases based on hyperspectral technologies. Hyperspectral analysis is a new subject that combines optical spectroscopy and image analysis methods, which makes it possible to simultaneously evaluate both physiological and morphological parameters. Among the physiological and morphological parameters are classifying healthy and diseased plants, assessing the severity of the disease, differentiating the types of pathogens, and identifying the symptoms of biotic stresses at early stages, including during the incubation period, when the symptoms are not visible to the human eye. Plant diseases cause significant economic losses in agriculture around the world as the symptoms of diseases usually appear when the plants are infected severely. Early detection, quantification, and identification of plant diseases are crucial for the targeted application of plant protection measures in crop production. Hence, this can be done by possible applications of hyperspectral sensors and platforms on different scales for disease diagnosis. Further, the main areas of application of hyperspectral sensors in the diagnosis of plant diseases are considered, such as detection, differentiation, and identification of diseases, estimation of disease severity, and phenotyping of disease resistance of genotypes. This review provides a deeper understanding, of basic principles and implementation of hyperspectral sensors that can measure pathogen-induced changes in plant physiology. Hence, it brings together critically assessed reports and evaluations of researchers who have adopted the use of this application. This review concluded with an overview that hyperspectral sensors, as a non-invasive system of measurement can be adopted in early detection, identification, and possible solutions to farmers as it would empower prior intervention to help moderate against decrease in yield and/or total crop loss.

  • The purpose of this study was to present basic data in the nursing practice for the management of living kidney donor by understanding the nature and meaning of kidney donors, experiences. The research subjects were 11 living kidney donors who had donated from Mar 1991 to Feb. 1994 and discharged from the 3 hospitals in Pusan. Data has been collected by Intensive interview with donors. The data analysis has made by phenomenological method of Van Kaam for understanding the phenomenon and meaning of their experiences. The experiences of kidney donors were analyzed into the 4 situations, that is,'motivation of kidney donor', 'decision time to make kidney donation', 'pre-opperation','after donation'. The descriptive expression and common elements were drawn from original data of each situation on the basis of subjects' own words. From each situation, the com-mon elements of kidney donors' experiences were integrated, summarized and described as follows 1. Motivation of kidney donation They wanted to donate their kidney because of empathy of pain on the groung of love to the recipient and with exppectation of successful kidney transplant or as a solution of economic difficulty. 2. Experiences in deciding to make kidney do-nation In deciding to make kidney donation, donors had love toward the recipients. But they experienced conflict too. 3. Experiences before being operated on donated kidney In experiences from deciding to make kidney do nation to preoperation, donors had love toward the recipients. But they also felt anxiety or dissatisfaction. Therefore, they controlled their mind by their faith, support of medical staff or support of society. And they experienced regret for the sociological cognition or financial apprehension. 4. Experiences after kidney donation After kidney donation, donors experienced satis-faction and accompplishment in spite of mental and physical discomfortness, while they felt sense of loss / disappointment, repentance, regret, and apprehension of progress toward their condition. Thus, kidney donors donated their kidney on the ground of empathy and love to the recipient and with expectation of successful kidney transplant. But during the process of kidney donation, they ex perienced conflict, love, anxiety, regret, apprehension of economy. And after donation, they felt sense of satisfaction and accomplishment, while they felt sense of discomfortness, loss / disappointment, re-gret, repentance, or apprehension of progress toward their condition. This result contribute to nurses' role not only for the management of living kidney donors but also for the management of cadaver donors' family.
