  • We study the effects of phonon interaction on the superconducting pairing in the high $T_c$ superconductors (HTSC). Using coupled BCS gap equations, we found that phonon interaction can induce a s-wave component to the d-wave gap, mediated by Antiferromagnetic (AFM) spin fluctuations, in the (D+iS) form. However, $T_c$ is not enhanced compared to the pure d-wave pairing without phonon interaction. On the other hand, anisotropic phonon interaction can dramatically enhance the d-wave pairing and $T_c$ itself, together with the AFM spin fluctuation interaction. This ($D_{AFM}+D_{ph}$) type pairing exhibits strongly reduced isotope coefficient despite the large enhancement of $T_c$ by phonon interaction.

  • This study explored the trend of postwar period American furniture design and analyzes the contexts of the trend. To be more specific, this study categorized the types of the styles or "looks" of furniture which were dominant in postwar period America: the machine look ; the handicraft look ; the biomorphic look. The background and the context for each look were traced back and analyzed both diachronically and synchronically. Based on the analysis, this study provided two conclusions. First, postwar period American furniture design is in many ways indebted to the World War II, because the war itself and postwar economic revival produced high demands for furniture, which consequently produced a variety of looks of furniture. Second, the furniture design in this period is attributed to commercialism and consumer-oriented design policy formulated in the mid 1920′s when American design established its own identity separating from European avant-gardism.

  • Beginning in the northwestern region of India, and spreading through Central Asia and the rest of Asia along the Silk Road, the making of colossal Buddha statues has been a major theme in Buddhist art. The colossal Buddha statues predominantly feature Śākyamuni (the Historical Buddha), Maitreya (the Future Buddha), and Vairocana (the Transcendant Buddha), and they were fashioned out of religious devotion and frequently in conjunction with notions of Buddhist kingship. This paper examines the religious, social and political circumstances under which these colossal statues were made, focusing on examples from Central and East Asia made during the first millennium CE. Beginning in the 1990s, there was a revival of making colossal Buddha statues across China and elsewhere. The paper also briefly compares the current wave of building colossal Buddha statues with historical examples.

  • This study is designed to analyze the production, employment, value added and income impacts tha, in the event of designation and development of Haeundae as 'Convention, Movie, Marine Leisure Special Zone', its marine sector would have on the local economy. The realization of marine leisure special zone of Haeundae in Busan is expected to lead to a direct and indirect investment of approx. \13.6 billion, resulting in \68.0 billion in production impact, 850 jobs in employment impact, \28.0 billion in value added impact and \14.5 billion in income impact. This is expected to give a boost to a stagnant local economy, offering opportunities for the revival of Busan's tourist industry.

  • This study investigated children's cognitions of physically impossible events by characteristics of the events. The 67 subjects were 3-, 5-, and 7-year old children from one day care center and one elementary school in Seoul. Children's responses to questions regarding the events were taped and transcribed. Cognition of the events was measured by recognition of impossibility, possibility of replication, and reasons for the possibility of replication of the events. Data were analyzed by ANOVA(repeated measures), and Pearson's correlation. Children's recognition of the impossibility of the events varied by type of task : Recognition of gravity tasks was different from irreversibility tasks, but there were no differences between recognition of irreversibility and gravity and between irreversibility and object permanence. The possibility of replication correlated significantly with reasons given by the children.

  • This paper describes a Transient Stability Education & Training Software that can make the students or beginners easily be familiar with power system stability problems. The Major objective of this study is to provide, for educational purpose, an interactive computer graphic tool that can facilitate power system study in highly user-friendly environment. The proposed software is designed to have the particular features such as follow : simulation with animation of the rotor, useful interactive scheme, various graphic illustrations related to critical factors of the stability, trace function including revival simulation with different processing speed. With these features, the software could be suitable for educational and training of students/beginners in power system stability engineering field.

  • In the 1970s, the radial artery was proposed as a coronary artery bypass graft but then was abandoned due to graft occlusion secondary to spasm during harvesting. Development of new pharmacologic antispasmodic agents and minimal traumatic harvesting techniques has led to the revival of the use of the radial artery in coronary artery bypass procedures. Harmonic Scalpel(Ultracision Inc, Smithfield, Rl) offers the surgeon the ability to perform less traumatic, spasm free, and rapid radial artery harvesting.

  • The ultimate purpose of this study is to revitalize the fishing community as the basis for the revival of the fisheries industry. The types of Eochon-Gye acceptance were analyzed as a basic study to achieve this purpose. According to the results of the study, it turned out that the head and the member of the Eochon-Gye had the same three Eochon-Gye acceptance types; that is, democratic, decision-making, and separatist types. However, the Eochon-Gye acceptance types by two groups differed in detail, even though they were named by the same names. Therefore, in order to devise an effective revitalization plan of the fishing community, it is necessary to reflect the detailed characteristics of each Eochon-Gye acceptance type owned by the two groups.

  • The Khitans were a Turco-Mongol clan who dominated China north of the Yangtze River during the early mediaeval period. They adopted and then adapted many of the cultural traditions of their powerful neighbours to the south, the Song Chinese. However, before their absorption into the Mongol Empire in the late 13th century they proved pivotal, firstly in the eastward expansion of the armies of Chinggis Khan, secondly, in the survival of the Persian heartlands after the Mongol invasions of the 1220s and thirdly, in the revival and integration of the polity of Iran into the Chinggisid Empire. Da Liao, the Khitans, the Qara Khitai, names which have served this clan well, strengthened and invigorated the hosts which harboured them. The Liao willingly assimilated into the Chinggisid Empire of whose formation they had been an integral agent and in doing so they also surrendered their identity but not their history. Recent scholarship is now unearthing and recognising their proud legacy and distinct identity. Michal Biran placed the Khitans irrevocably and centrally in mediaeval Asian history and this study emphasises their role in the establishment of the Mongol Empire.

  • The main purpose of the article is to analyze the features of the impact of digital technologies on environmental management in the public administration system of the regions. The revival of the economy and its digitalization, which emerged after the first wave of the economic crisis, is already fraught with an aggravation of the ecological situation in the region. Of course, the conventional model of economic growth has by now exhausted its capabilities and can be characterized as environmentally unsustainable. Digital technologies bring changes that cannot be ignored. Based on the results of the study, key aspects of the impact of digital technologies on environmental management in the public administration system of the regions were identified.
