The study investigated the continuing education program desirable for the academic librarian under digital circumstances. For this purpose the study investigated the education programs provided by the National Library of Korea, the American Library Association, and the Association of Research Libraries, and also undertook a questionnaire survey of academic librarians in Korea. As a result the study suggested user instruction, information retrieval, electronic licensing etc. as programs needed most by the academic librarians. And also suggested intellectual freedom, disaster planning, cooperation with faculty, presentation and teaching skill as desirable to be included in the continuing education program.

This paper developed an analytical software, called Simulation of Concrete Structures (SCS), which is used for numerical analysis of shear-critical prestressed steel fiber concrete structures. Based on the previous research at the University of Houston (UH), SCS has been derived from an object-oriented software framework called Open System for Earthquake Engineering Simulation (OpenSees). OpenSees was originally developed at the University of California, Berkeley. New module has been created for steel fiber concrete under prestress based on the constitutive relationships of this material developed at UH. This new material module has been integrated with the existing material modules in OpenSees. SCS thus developed has been used for predicting the behavior of the prestressed steel fiber concrete I-beams and Box-beams tested earlier in this research. The analysis could well predict the entire behavior of the beams including the elastic stiffness, yield point, post-yield stiffness, and maximum load for both web shear and flexure shear failure modes.

This paper presents experimental and numerical investigations of aluminum tubular members subjected to combined bending and web crippling. A series of tests was performed on square hollow sections (SHS) fabricated by extrusion using 6061-T6 heat-treated aluminum alloy. Different specimen lengths were tested to obtain the interaction relationship between moment and concentrated load. The non-linear finite element models were developed and verified against the experimental results obtained in this study and test data from existing literature for aluminum tubular sections subjected to pure bending, pure web crippling, and combined bending and web crippling. Geometric and material non-linearities were included in the finite element models. The finite element models closely predicted the strengths and failure modes of the tested specimens. Hence, the models were used for an extensive parametric study of cross-section geometries, and the web slenderness values ranged from 6.0 to 86.2. The combined bending and web crippling test results and strengths predicted from the finite element analysis were compared with the design strengths obtained using the current American Specification, Australian/New Zealand Standard and European Code for aluminum structures. The findings suggest that the current specifications are either quite conservative or unconservative for aluminum square hollow sections subjected to combined bending and web crippling. Hence, a bending and web crippling interaction equation for aluminum square hollow section specimens is proposed in this paper.

This study aims to examine Mark Twain's criticism of American capitalistic ideals in the late nineteenth century. During this second industrial revolution, industry showed rapid growth and capitalism established an order, while America suffered under the monopolization of capitalistic conglomerates. This resulted in the widening gap between the rich and the poor and the dehumanization caused by rapid industrialization. In A Connecticut Yankee in King Arthur's Court, Hank Morgan, the protagonist--who represents nineteenth-century America's industrialism, individualism, and capitalism--is sent back in time to the sixth century of Arthurian England. Hank attempts to introduce nineteenth-century technologies and machines to build a capitalistic system in the middle ages. However, Hank's efforts lead to disaster in which the country and civilization he worked to build is completely destroyed. Although Twain does not deny capitalistic ideals, he criticizes the "governmentality" that operates Hank's reform system to the extreme. Hank values efficiency and utilizes human beings as capital. Hank's economic reason not only transforms the Round-Table knights into speculators but also transforms their religious acts and abstract ideals into moneymaking businesses. The destructive ending anticipates the World Wars and the Great Depression in the first half of twentieth century and even serves to predict the dangers that follow.

As Oedipa Mass, the heroine of Thomas Pynchon's The Crying of Lot 49, is apparently associated with Oedipus, the hero in Sophocles' tragedy, this paper aims to show some of their similarities in quest theme and plot development as well as in the use of dramatic irony. Oedipus the King opens with a priest's pleas to relieve the Theban people from a plague and the king's promise to rid its cause by avenging the murder of the former king, as told by the oracle. Lot 49 begins as a Los Angeles law firm informs Oedipa that she is named as the executrix in her former lover Inverarity's will to sort out the mogul's estate. Ironically, however, Oedipus' investigation reveals himself to be the very cause of the national disaster, the murderer for whom he searched. Likewise, Oedipa starts her inquiry dedicating herself to make sense out of what Inverarity had left behind, only to find that the legacy was America. Sophocles and Pynchon both employ dramatic irony to provide a controlling principle for plot development in their works. In Oedipus the King, Sophocles creates mounting tension as well as distance between the reader's knowledge and the protagonist's ignorance, compressing the play's action into the moment that Oedipus discovers his real identity. For dramatic irony, however, Pynchon tends to work through authorial comments and utilize allegorical meanings of the characters' names, directing his novel at illuminating Oedipa's discovery of Inverarity's legacy as well as the meaning of Tristero, an underground postal service system. Unlike Oedipus the King that proceeds on a single line of action, Lot 49 develops in esoteric, multi-layered allusions and intricately-interrelated double strains involving Oedipa's roles as executrix and quester. At the end of Sophocles' tragedy, Oedipus stabs his eyes and decides to live in exile, realizing that, blinded, he begot his children through his mother; Oedipa comes to a painful realization that she allowed her former lover to create death-orienting America without her diversity and moral system in old times. As Oedipa now discovers herself through her search for Tristero, her tragic spirit lies in her determination to confront her binary choices between two Americas: transcendence or entropy, the Tristero possibility or Inverarity's America. Ultimately, Oedipa tries to find who will be the bidder for the Tristero forged stamps designated as lot 49, awaiting the auctioneer's cry and the "crying" of a new-born America.

Dose creep is one of clinical errors that arises from the tester's inexperience or carelessness, and according to Task Group #116 of American Association of Physicists in Medicine, its continued occurrence is being reported in the digital method. At this point, the demand for an automatic exposure control device that minimizes the dose creep phenomenon and can improve reproducibility is increasing. In this study is to consider the automatic exposure control device sensor that can is not only easy to produce, but also reduce the dose creep phenomenon by conducting a research on high-efficient semiconductor sensor. As a result, the Intrinsic-type and PIN-type sensors have excellent optical property compared to Ref sensor, would have less shading effect, and have relatively low sensitivity, but would provide accurate feedback signals to automatic exposure control device with its consistent tendency according to exposure condition changes.

The purpose of this study is to suggest ways to improve medical librarians' educational programs to improve domestic medical library user services. To this end, the role of medical librarians was investigated, and the education areas were itemized, and then the MLA in the US and the KMLA in Korea were compared and analyzed. As a result, the improvement points for medical librarian education programs in Korea are: First, expansion of certification programs that select various types of education programs, education areas, education contents, and specialized fields, collaboration programs with related institutions, and education programs that advocate the value of KMLA are required. Second, there is a need for various educational programs in the current educational areas, such as 'research support service' and 'education/education design/consultation'. In particular, it is necessary to provide 'consumer health information service' and 'disaster information service' for which there is no education at all. In addition, it is necessary to precede the establishment of regulations on the domestic medical librarian education curriculum for the education of various 'information services in the field related to medicine'. Third, it is necessary to provide online education contents for librarians who have difficulty participating in face-to-face education.
