In this article, we focus on some notions of prime submod- ules over a commutative ring with identity. Suppose R is a commutative ring with identity and M is an R-module. A proper submodule N of M is called prime if rm is element of N implies r element of (N : M) or m element of N. In this article we give a generalized version of prime submodule in its localization which named as S(N)-almost prime submodule. This generalization was obtained by creating generalized version of almost prime submodule such that the submodule is not al- most prime but its localization is almost prime. Furthermore, some characterizations of S(N)-almost prime submodules and its relation to S(I)-almost prime ideals are given in this article.
Change and Continuity in the Political Attitudes of Canadian University Students, 1986-2011
Steven Holloway(Steven Holloway ),Youngwon Cho(Youngwon Cho) 한국캐나다학회 2013 Asia-Pacific Journal of Canadian Studies (APJCS) Vol.19 No.2
While Political Science is taught at nearly every university in Canada, little is known about the political attitudes of the Canadian students actually taking courses in the discipline. Beyond anecdotal evidence based largely on personal impressions, there has been no other indicator to gauge our students’ political dispositions and preferences, especially over an extended period of time. We shed some light on this issue by presenting the findings of a survey of first-year students taking an introductory course in Political Science at [name withheld for blind review]. Spanning over 25 years from 1986 to 2011, the survey and its findings provide a useful window into the evolving pattern of political attitudes among our first-year students, which include, among others: ideological inclinations, both self-identified and more objectively measured; party preferences; views on Quebec separatism; support for Canada’s international activism; attitudes toward the US; and assessment of international economic openness.
Chondroid metaplasia of paraspinal connective tissue in the degenerative spine

A 51-year-old male was routinely biopsied during a paraspinal muscle study. The biopsy sample was taken from the right erector spinae muscle at the fourth lumbar vertebra. The patient had no history of (diagnosed) major back trauma. The obtained sample was histologically analyzed (hematoxylin and eosin, safranin O), and complementary magnetic resonance imaging was performed. The biopsied sample contained chondroid tissue. Based on its location, the biopsy sample was appointed as chondroid metaplasia. Although chondroid metaplasia is not uncommon in humans, this is the first report of chondroid metaplasia within the paraspinal connective tissue. We propose a novel mechanism to explain the paraspinal chrondrogenic changes, related to spinal degeneration.
The Role of Inflammatory Mediators in the Pathogenesis of Otitis Media and Sequelae

This review deals with the characteristics of various inflammatory mediators identified in the middle ear during otitis media and in cholesteatoma. The role of each inflammatory mediator in the pathogenesis of otitis media and cholesteatoma has been discussed. Further, the relation of each inflammatory mediator to the pathophysiology of the middle and inner ear along with its mechanisms of pathological change has been described. The mechanisms of hearing loss including sensorineural hearing loss (SNHL) as a sequela of otitis media are also discussed. The passage of inflammatory mediators through the round window membrane into the scala tympani is indicated. In an experimental animal model, an application of cytokines and lipopolysaccharide (LPS), a bacterial toxin, on the round window membrane induced sensorineural hearing loss as identified through auditory brainstem response threshold shifts. An increase in permeability of the blood-labyrinth barrier (BLB) was observed following application of these inflammatory mediators and LPS. The leakage of the blood components into the lateral wall of the cochlea through an increase in BLB permeability appears to be related to the sensorineural hearing loss by hindering K+ recycling through the lateral wall disrupting the ion homeostasis of the endolymph. Further studies on the roles of various inflammatory mediators and bacterial toxins in inducing the sensorineumral hearing loss in otitis media should be pursued.
Collection, Mission, Action. Bridge the Museum to the World.
Steven Engelsman 한국박물관학회 2005 博物館學報 Vol.- No.8
Dear‘ colleagues, Bridges to the world - the umbrella title of this year's AAM convention has puzzled me quite a bit. If you talk about building blidges, you talk about divides, don’t you? Is there indeed a divide between museums and the world? Are museums ivory towers? I find it hard to believe, celtainly here in the US. You all know your external stakeholders, don’t you, and your trustees, they do represent the outside world, don’t they? %이at has also puzzled me was that notion of bridge to ?1e world. It’s so unidirectional: from the museum to the world rather than between the two of them. Why is that so? Is there a feeling amongst museums that they will have to act now, otherwise become too isolated and obsolete?
