    Thesis(Master) --KDI School:Master of Public Management,2020.Korea is a country that emits large amounts of greenhouse gases, so Korea plans to drastically expand the supply of renewable energy to supply and demand eco-friendly energy while keeping pace with the changes in global energy policy stances caused by climate change. Especially, it plans to supply most of renewable energy with solar and wind power. In order to meet the government''s recent renewable energy policy, Korea Water Resources Corporation (K-water) and Korea Rural Community Corporation are expanding large-scale floating solar power projects using water surface. In promoting floating solar power projects, issues of ''environmental'' related to water pollution, water ecological disturbance, heavy metal extraction, electromagnetic wave-related environmental hazards, and damage to the landscape are raised. And there are problems with delayed or terminated projects due to public opposition to development caused by damage to residents in the development area. Experts think that ''environmental'' and ''resident acceptance'' are the biggest problems in large-scale floating solar power development. In order to solve the environmental problem, it is necessary to comprehensively study the impact on water quality and aquatic ecosystems and environmental risks from a mid- to long-term perspective through continuous monitoring. And by sharing objective facts with the residents, we will be able to resolve doubts about the environmental problem. And resident acceptance can be enhanced when it is shared with the residents as a real benefit by forming a trust relationship through continuous communication with local residents, and by sharing the profits generated through the project with the business operator and local residents. From the initial planning stage to the construction and operation of the project, the business can be smoothly promoted only by considering the major issues, response plans, decisions, and expected effects response plans. In this study, an in-depth interview was conducted on the floating solar power development of Chungju Dam and Hapcheon Dam to experts participating in the development of floating solar power projects. Opinions were collected and analyzed to improve the social acceptability of floating solar power generation. It is meaningful that it presents effective strategic implications.1. Introduction 2.

    E. L. Doctorow's Idea of Justice

    Get PDF
    To the question "Although outwardly all of your novels seem different, do you see any connecting themes running through them," E.L. Doctorow answered, "One of my working principles is not to know too clearly or too objectively what I'm doing. The actual moment of composition is anything but cerebral or planned. I do have certain preoccupations, but I wouldn't call them anything more than preoccupations. For instance, I find myself extremely sensitive to the idea of injustice. The idea that something is not fair really gives me energy in writing. The idea of the imposition of people on each other-whether in their personal relationships or in large historical terms-seems to intrigue me." John Gardner also said, "E.L. Doctorow, m Ragtime, urges social justice in a more or less moving and persuasive way, but he IS not concerned with true morality." These two statements suggest that Doctorow's deep interest in novel writing is in the problem of justice in society

    A Talk with Bernard Malamud

    I was fortunate to meet Mr. Malamud and have this interview after he read my article, "Bernard Malamud's Renewal of the Human Spirit," which deals with three of his seven novels, The Assistant and A New Life and Dubin's Lives. AU of these novels are written with his own definition of art, on the basic theme of self-transcendence, exploring the idea of suffering, and with deft use of irony. The article, which will be published in the annual journal of American Studies Association of Korea, examines the fact that the heroes in his navels have the belief that their life can renew itself and yearn for a better life, even though they get extremely caught up in isolation and suffer deep frustration. I sent the article to Mr. Malamud who was a 1981""'1982 fellow of Center for Advanced Studies in the Behavioral Sciences, Palo Alto, California. On February 2, 1982, I interviewed him at his office which overlooks Stanford University. He had many enlightening comments about art, suffering, self-transcendence, morality, democracy, freedom, love, Zen Buddhism, the image of a bird in his novels, the technique of foreshadowing, and translations. He is the author of seven novels and three collections of short stories: The Natural(l952), The Assistant (1957), A New Live(l961), The Fixer (l966), Pictures of Fidelman: An Exhibition (I969), The Tenants(I971), Dubin's Lives (l979), The Magic Barrel (l958), Idiots First (l963), and Rembrandt's Haf(I973)

    Direct observation of a hypersonic band gap in two-dimensional single crystalline phononic structures

    Get PDF
    Brillouin light scattering is employed to record the phonon dispersion relation of two-dimensional (2D) hypersonic phononic crystals with square lattice plane group p4mm symmetry. The samples are single crystalline arrays of cylindrical holes with a lattice constant of 750 nm and 35% porosity patterned in epoxy using interference lithography. The dispersion relation reveals the presence of a phononic band gap between 1.21 and 1.57 GHz at the edge of the first Brillouin zone for elastic waves propagating along the [10] direction and conclusively demonstrates a band gap in a single crystalline 2D polymer based phononic structure at hypersonic frequencies.open312

Copyright @ 2011 Elsevier B.V.The fate and behaviour of two groups of endocrine disrupting chemicals, steroid estrogens and nonylphenol ethoxylates, have been evaluated during the anaerobic digestion of primary and mixed sewage sludge under mesophilic and thermophilic conditions. Digestion occurred over six retention times, in laboratory scale reactors, treating sludges collected from a sewage treatment works in the United Kingdom. It has been established that sludge concentrations of both groups of compounds demonstrated temporal variations and that concentrations in mixed sludge were influenced by the presence of waste activated sludge as a result of transformations during aerobic treatment. The biodegradation of total steroid estrogens was >50% during primary sludge digestion with lower removals observed for mixed sludge, which reflected bulk organic solids removal efficiencies. The removal of nonylphenol ethoxylates was greater in mixed sludge digestion (>58%) compared with primary sludge digestion and did not reflect bulk organic removal efficiencies. It is apparent that anaerobic digestion reduces the concentrations of these compounds, and would therefore be expected to confer a degree of protection against exposure and transfer of both groups of compounds to the receiving/re-use environment.Thames Water, Yorkshire Water, and EPSRC

    Ectopic adrenal gland tissue in the left ovary of an elderly woman: a case report

    Ectopic adrenal gland in the ovary is very rare case, and even more rarer in older women. We reported a case of ectopic adrenal tissue as an incidental finding in left ovary from a 68-year-old woman. She presented with bearing down sensation due to uterine prolapse for 5 years. Upon physical examination, uterine prolapse grade III, cystocele, and rectocele were observed. Ultrasonography findings showed 0.69 cm intramural myoma, and no specific findings were found in the bilateral adnexae. She underwent a total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and anterior-posterior repair. The final pathologic diagnosis of the case was ectopic adrenal gland tissue in the left ovary and uterine leiomyoma. No eventful reactions were observed during hospitalization and after discharge. Although ectopic adrenal gland rarely occurs in elderly women and in the pelvic ovaries, it has a risk of neoplastic transformation and accompanying germ cell tumor and sex cord tumor. Hence, if the ectopic adrenal gland tissue is suspected during surgery, the tissue should be removed. Additionally, by closely examining the contralateral ovary, determining whether other lesions are suspected is necessary. If the other lesions including germ cell tumor or sex cord tumor are suspected, a biopsy of the contralateral ovarian tissue should be performed. Thus, gynecologists must have knowledge about ectopic adrenal gland tissues
