Korea has started to pay attention to civic journalism in recent years while it initially emerged in the United State since late 1980s. Furthermore, albeit some discernable limitations, the Internet has played an important role in fertilizing civic journalism as indicated by the emergence of online news media and the increasing number of civic journalists engaged in the online activities. Whereas there are some patterns of civic journalism practice and the civic influence commonly observed in both countries, there are significant factors that distinguish th1e case of Korea from that of the U.S. The purpose of this study is to compare the two countries in terms of the patterns of civic journalism practice and civic influence. This goal has been achieved by analyzing ‘CNN iReport’ in the U.S. and ‘Ohmynews’ in Korea, both of which are prime civic journalism websites. Those websites have been compared in light of four standards of civic journalism: first, the degree of post-objectivism; second, the search for effective resolutions of social problems; third, civic engagement in the news making process to enhance bottom-up agenda setting; and finally, citizens’ interaction with the news. The results reveal that the American civic journalism website is more likely to shed light on deviating from the principle of objectivity and seeking alternatives and resolutions of social problems. Moreover, it effectively utilizes civic engagement in the news Abstracts 551 making process as indicated by the higher numbers of civic journalists and civic news resources. Also, readers’ interaction with the news was found to be more active in the iReport website than in the Ohmynews.

According to Chomskyan grammar, humans can generate and understand an unbounded number of grammatical sentences. Against the background of pure and idealized linguistic competence, this linguistic productivity is argued and understood. In actual utterances, however, there are many limitations of productivity but they are said to come from the general constraints on performances such as capacity of short term memory or attention. In this paper I discuss a problem raised against idealized productivity. I argue that linguistic productivity idealizes our linguistic competence too much. By separating idealized competence from the various constraints of performance, Chomskyan theorists can argue for unlimited productivity. However, the absolute distinction between grammar (pure competence) and parser (actual psychological processes) makes little sense when we explain the low acceptability(intelligibility) of center embedded sentences. Usually, the problem of center embedded sentence is explained in terms of memory shortage or other performance constraints. To explain the low acceptability, however, we need to assume specialized memory structure because the low acceptability occurs only with a specific type of syntactic pattern. 1 argue that this special memory structure should not be considered as a general performance constraint. It is a domain specific (specifically linguistic) constraints and an intrinsic part of human language processing. Recent development of Chomskyan grammar, i.e., minimalist approach seems to close the gap between pure competence and this type of specialized constraints. Chomsky's earlier approach of generative grammar focuses on end result of the generative derivation. However, economy principle (of minimalist approach) focuses on actual derivational processes. By having less mathematical or less idealized grammar, we can come closer to the actual computational processes that build syntactic structure of a sentence. In this way, we can have a more concrete picture of our linguistic competence, competence that is not detached from actual computational processes.

In 2008, the Korean Supreme Court came across a plaintiff's claim to return his deceased father who had left family more than four decades ago and lived with another spouse(de facto) in the meantime to be buried after death in a cemetery of his own choice. The major opinion decided to approve the claim, on the ground that the first legitimate son should be the "head worshiper" prescribed in the article 1008-3 of the Korean Civil Code and that the corpse belong to the head woshiper, i. e. the head woshiper has a special "limited ownership" over the corpse for the purpose of its burial and worship, adding that a deceased's disposition inter vivos, if any, be only ethically but by no means legally binding others, including the head worshiper of course. Here scrutinized are the historical developments starting from the Roman criminal law of sepulchri violatio(trespass to grave) through the Canon law of the Middle Age and the doctrinal reactions to the challenges of anatomy and surgery to the formation of the "supporting the deceased" theory in Germany as well as the similarities in other european continental countries(Switzerland, Austria and France). The comparative review shows that the right of remaining family could neither be identified as limited "ownership" nor that the controversy over a corpse be solved by exclusively attributing/distributing it to one/some of the descendants. In principle, the question should be approached in the extension of family support.

This study aims at investigating the size-dependent free vibration of porous nanoplates when exposed to hygrothermal environment and rested on Kerr foundation. Based on the modified power-law model, material properties of porous functionally graded (FG) nanoplates are supposed to change continuously along the thickness direction. The generalized nonlocal strain gradient elasticity theory incorporating three scale factors (i.e. lower- and higher-order nonlocal parameters, strain gradient length scale parameter), is employed to expand the assumption of second shear deformation theory (SSDT) for considering the small size effect on plates. The governing equations are obtained based on Hamilton's principle and then the equations are solved using an analytical method. The elastic Kerr foundation, as a highly effected foundation type, is adopted to capture the foundation effects. Three different patterns of porosity (namely, even, uneven and logarithmic-uneven porosities) are also considered to fill some gaps of porosity impact. A comparative study is given by using various structural models to show the effect of material composition, porosity distribution, temperature and moisture differences, size dependency and elastic Kerr foundation on the size-dependent free vibration of porous nanoplates. Results show a significant change in higher-order frequencies due to small scale parameters, which could be due to the size effect mechanisms. Furthermore, Porosities inside of the material properties often present a stiffness softening effect on the vibration frequency of FG nanoplates.

We consider a general class of real-valued Levy processes {X(t), $t\geq0$}, and obtain suitable large deviation results for the empiricals L(t, A) defined by $t^{-1}{\int^t}_01_A$(X(s)ds for t > 0 and a Borel subset A of R. These results are used to obtain the asymptotic behavior of P{Z(t) < a}, where Z(t) = $sup_{u\leqt}\midx(u)\mid$ as $t\longrightarrow\infty$, in terms of the rate function in the large deviation principle. A subclass of these processes is the Feller class: there exist nonrandom functions b(t) and a(t) > 0 such that {(X(t) - b(t))/a(t) : t > 0} is stochastically compact, i.e., each sequence has a weakly convergent subsequence with a nondegenerate limit. The stable processes are in this class, but it is much larger. We consider processes in this class for which b(t) may be taken to be zero. For any t > 0, we consider the renormalized process ${X(u\psi(t))/a(\psi(t)),u\geq0}$, where $\psi$(t) = $t(log log t)^{-1}$, and obtain large deviation probability estimates for $L_{t}(A)$ := $(log log t)^{-1}$${\int_{0}}^{loglogt}1_A$$(X(u\psi(t))/a(\psi(t)))dv$. It turns out that the upper and lower bounds are sharp and depend on the entire compact set of limit laws of {X(t)/a(t)}. The results extend to random walks in the Feller class as well. Earlier results of this nature were obtained by Donsker and Varadhan for symmetric stable processes and by Jain for random walks in the domain of attraction of a stable law.

Tuberculous cervical lymphadenitis is one of common cause of neck mass in young adult in Korea. Tuberculous cervical lymphadenitis known as scrofula was being treated by the 'Royal Touch' in the 5th century and by surgery in the 17th century, yet the principle of the treatment is still controversal. We report the clinical evaluation and therapeutic result about 121 tuberculous cervical lymphadenitis. The result were as follows: 1) The annual incidence(1985-1994) was 30.5 % (37 cases: 1985-1986), 17.7 % (21 cases: 1990-1992). 19.8%(24 cases: 1994). 2) The age of highest incidence was 20-29 year old age group in 41.3% (50 cases) and female predominated over male by 1.8 : 1. 3) The duration of disease was less than 6 months, in 85.9% (104 cases). 4) The most commonly involved LN group was superficial cervical group in 69.4% (84 cases), and difference between Rt & Lt, was not significant. 5) The most common symptom and local finding(P/E) were, painless swelling of LN in 74.3 % (90 cases) and single mass in 59.5 % (72 cases). 6) In seasonal variation, 85.9% (104 cases) was spring and summer. 7) Procedures except biopsy for evaluation were chest PA, AFB smear & culture(sputum), Mantoux test, USG, CT and, Associated extracervical tuberculous lesions were lung, axilla, breast. 8) In operation method (involving biopsy), Excision was 68.5 % (83 cases), neck dissection was 6.6% (8 cases). 9) The Modality, Duration and side effect of antituberculous medication: INH-Rifampin­Ethambutol was 66.1 % (88 cases), duration was 1 year in 84.3% (102 cases), side effects were severe GI trouble (24.8%), liver function damage (3.3%). 10) 3 cases recurred on the same site after 2 yrs(2 cases) and 4 months(1 case) and its treatment was curretage or I & D, with antituberculous medication.

Knowing the mean free paths (MFPs) of thermal phonons is an essential step in performing heat transfer analysis for nanomaterials, and in determining the optimum design for tailoring the heat transfer characteristics of nanomaterials. In this study, we present a method that can be used to calculate accurately the phonon MFP spectra of nanostructures based on simple phonon kinetic theory. Here, the kinetic theory may be employed by extracting only the diffusive-transport part of the phonon spectrum (i.e., the MFPs are less than a thermal length). By considering phonon dispersion and polarization effects, the phonon MFP distributions of silicon at room temperature are calculated from phonon transport properties and the spectral MFP. Our results are validated by comparison with those of the first principle and MFP spectroscopy data.

The tendency of the Minimalism in the contemporary a architecture is based on Mies van der Rohe s saying ‘나SS IS m more" as the principle of the Minimal art and its formative c composition. It can be divided into technical Minimalism p prevailed in Northern Europe and the zone of German l language, and the regional one in Southern Europe and S Southern America. The former is interested in the experiences of the techniques and materials, and the latter in that of the s space and the place through the simple forms. The minialistic approach to the architecture is nat only m methodological one. It accepts the concept and the construction of architecture as 2 axes for making it keeps the tradition and c communication with the master builder, the materials, and i염 m means to compound. The expressive characteristics of works in M Minimalism are 1) as the formal issue, it is simple, self-referring. without any symbol or any allusion, and compounds the r repetitive forms as the comceptual aspec않 of architecture, 2) it h has the characteristies such as the approach directly to the m means by which architecture made, the critical interests to the m material attributes, and the capacity to the contemporary t technology as the issue of technique and materials, 3) regarding t the space and the place, it shows the good sense to the site in t the sphere intervention of architecture 1e Maininlalism architecture has i않 impotance in the point t that it seeks to the qualities immanent in architecture by s showing the marvelous status through discovering the i immanent properties of the site, program materials, and the s structure, and also it begins new way of interpreting a architecture with new viewpoint to the its essence as well as a architecture itself.self.

The politics penetrating through the contemporary art since modernism to postmodernism is to accomplish the 'Non-representation' in the artworks. This study argues that postmodernism did not put an end to the formalistic feature of modernism but intended to accomplish it. Modernist art aimed at purity, i.e. self-referential and self-definition art advocated by Clement Greenberg, and it carne to the end by accomplishing flatness and materiality. It was an 'evasion to the matter' which allocated the object from visuality of outer object to the psychic image of the subject. It failed being 'non-representational' as what it really achieved was transition of object. Jean Baudrillard's theory tried to overcome the representational quality by 'being simulacre'. In the representative artworks of the past, the meaning of artworks was reverted under the outer context or object. The meaning again failed being 'Non-representational' as it was restored to the psychic image of the subject in modernist artworks where the definite illusion was demolished Meanwhile, artwork advocating simulacre acquired Non-representational quality by liberating from both models. It did not deconstruct the self-referential tendency of modernism but maximized the Non-representational modernistic principle. After creating 'Non-representation' through simulacre, the existential status and function of an artwork is the inclination and moral of contemporary art as 'Non-representation'. The image theory of Henri Bergson sets the existential status of 'image' as it does not belong to either subject nor object. It provides significant foundation for arguing the existential status of simulacre. Moreover, though an artwork as a fragment forming a movement image in the world cannot represent the object, it can however sustain certain kind of fractal resemblance with the world by letting the two parties communicate. The theory of sense by Gilles Deleuze is of profound significance as it specifically indicated way how the stage of absorption through the unity of subject and object is realized in forms of artworks, and configured the latent and invisible energy.

Parametric studies were performed to assess the sensitivity in determining the maximum in-vessel heat removal capability from the core material relocated into the lower plenum of the reactor pressure vessel (RPV）during a core melt accident. A fraction of the sensible heat can be removed during the molten jet delivery from the core to the lower plenum, while the remaining sensible heat and the decay heat can be transported by rather complex mechanisms of the counter-current flow limitation (CCFL) and the critical heat flux (CHF）through the irregular, hemispherical gap that may be formed between the freezing oxidic debris and the overheated metallic RPV wall. It is shown that under the pressurized condition of 10MPa with the sensible heat loss being 50% for the reactors considered in this study, i.e. TMI-2, KORI-2 like, YGN-3&4 like and KNGR like reactors, the heat removal through the gap cooling mechanism was capable of ensuring the RPV integrity as much as 30% to 40% of the total core mass was relocated to the lower plenum. The sensitivity analysis indicated that the cooling rate of debris coupled with the sensible heat loss was a significant factor The newly proposed heat removal capability map (HRCM) clearly displays the critical factors in estimating the maximum heat removal from the debris in the lower plenum. This map can be used as a first-principle engineering tool to assess the RPV thermal integrity during a core melt accident. The predictive model also provided ith a reasonable explanation for the non-failure of the test vessel in the LAVA experiments performed at the Korea Atomic Energy Research Institute (KAERI), which apparently indicated a cooling effect of water ingression through the debris-to-vessel gap and the intra-debris pores and crevices.
