  • What is the foundation of mathematical thinking? Is it logic based symbolic language system? or does it rely more on mental imagery and visuo-spatial abilities? What kind of neural changes happen if someone's mathematical abilities improve through practice? To answer these questions, basic cognitive processes including long term memory, working memory, visuo-spatial perception, number processes are considered through neuropsychological outcomes. Neuronal changes following development and practices are inspected and we can show there are neural networks critical for the mathematical thinking and development: prefrontal-anterior cingulate-parietal network. Through these inquiry, we can infer the answer to our question.

  • Soon after joining the Canadian Confederation in 1867, the province of Quebec adopted the phrase Je me souviens ("As I recall") as its 'national' motto, although many Qu?b?cois do not remember today what they were supposed to memorize, as collective subject, when their government voted this motion. My thesis is that contrary to other countries which have a strong sense of history based on a secular tradition, this process was more complicated in Quebec - as if a collective memory loss lied at the heart of it's history. Through a rereading of Hubert Aquin's cult novel, Trou de m?moire (in its English translation Blackout), first published in 1968, I try to illustrate this paradox and to emphasize the heuristic functions of memory blanks, gaps and lapses in certain postmodern narratives, after the historical breakdown of "the great narratives" (Lyotard). In this perspective, the example of Quebec, through the voice of one of its more gifted yet controversial novelist, can be seen as emblematic of what happens when the mnemonic impossibility of rewriting history opens up new possibilities for writing fiction.

  • Rupture of the pectoralis major muscle typically occurs in the young, active male. Acute management of these injuries is recommended; however, what if the patient presents with a chronic tear of the pectoralis major? Physical exams and magnetic resonance imaging can help identify the injury and guide the physician with a plan for management. Nonoperative management is feasible, but is recommended for elderly, low-demand patients whose functional goals are minimal. Repair of chronic tears should be reserved for younger, healthier patients with high functional demands. Although operative management provides better functional outcomes, operative treatment of chronic pectoralis tears can be challenging. Tendon retraction, poor tendinous substance and quality of tissue, muscle atrophy, scar formation, and altered anatomy make direct repairs complicated, often necessitating auto- or allograft use. We review the various graft options and fixation methods that can be used when treating patients with chronic pectoralis major tears.

  • Let M be a minimally immersed closed hypersurface in $S^{n+1}$, II the second fundamental form and $S = \Vert II \Vert^2$. It is well known that if $0 \leq S \leq n$, then $S \equiv 0$ or $S \equiv n$ and totally geodesic hypersheres and Clifford tori are the only possible minimal hypersurfaces with $S \equiv 0$ or $S \equiv n$ ([6], [2]). From these results, Chern suggested some questions on the study of compact minimal hypersurfaces on the sphere with S =constant: what are the next possible values of S to n, and does in the ambient sphere\ulcorner By the way, S is defined extrinsically but, in fact, it is an intrinsic invariant for the minimal hypersurface, i.e., S = n(n-1) - R, where R is the scalar, curvature of M. Some partial answers have been obtained for dim M = 3: Assuming $M^3 \subset S^4$ is closed and minimal with S =constant, de Almeida and Brito [1] proved that if $R \geq 0$ (or equivalently $S \leq 6$), then S = 0, 3 or 6, Peng and Terng ([5]) proved that if M has 3 distint principal curvatures, then S = 6, and in [3] Chang showed that if there exists a point which has two distinct principal curvatures, then S = 3. Hence the problem for dim M = 3 is completely done. For higher dimensional cases, not much has been known and these problems seem to be very hard without imposing some more conditions on M.

  • PoongLyuYak exists everywhere. If you read the poem and get inspired, it becomes poem Yak (詩藥, poem medicine). If you look at the picture and fall it, it becomes picture Yak. When you feel refreshed by travelling, it becomes travel Yak. Music, dance, movie, nature, etc. are very nice examples. Even a leisurely life of driving, eating out, and drinking coffee is good PoongLyuYak for the body. Whether you're alone or in a group, if you can enjoy it, it's good medicine. According to the logic of the windy and flowing world, anything that can transform one's emotions, whether happy, sad, or trivial, can be a PoongLyuYak. This PoongLyuYak may be more effective than oral medications, inhalants, ointments, or injections. Rather than simply watching, listening, or imitating others, the effect is enormous when participating directly and performing and creative activities. The pleasure of seeing Heung-min Son playing soccer is also a PoongLyuYak, but it can be more enjoyable and the medicinal effect is much greater if you enjoy soccer yourself. Here are some examples of PoongLyu medicines the authors took with the joy of creation.

  • What if the memory is not erased but continues to exist in the head as it was before? The typical answer to this question would be summarized as the "love for memory". It is almost unbearable that the memory is erased, forgotten or replaced with others. Even though three episodes may be understood as separate things, they have a different image when they are seen under one subject . he three episodes impresses the people with their unique fantastic images and artistic air. In the episode of , we can see a woman who is so much concerned with her past memory so that she does not love the present. In this episode, we can realize how much destructive the bad past memory gives effect on a woman and how memory can give bad effect on a person if that does not connect the past and the present. The work criticizes the society whichdoes not understand the current problems by depicting a person who is so preoccupied with the thing near that person only. shows that the dream is meaningless if people have the future dream without understanding what they really want. Theaudience is absorbed to each hero or heroin who is so obsessed with the past, present and future. What we can feel from these three works is the doubt about the human society which is so much preoccupied with the pessimism and the individuals who do not recognize the importance of the present because they are so much obsessed with their superficial past, present and future as well as the society where they live.

  • The purpose of this study is to present the study method in order to analysis the fashion phenomena in ppular culture by popular culture theory. The method of this study is showed the method fo fashion culture, after it was examined that the trends of popular cultural method, the type of Korean popular culture discussion, and the relationship of fashion and popular culture. The results of this study are following as ; 1. Analysis of this study are structuralism stand and culturalism stand, and the application of criticism about the cultural technology in a new stand by means of the composition of Gramscic, A and Foucault. 2. Application of the ethnographic access method as anthroppological approach method about C. Geertz'culture. This si to describe and interpret the practice of subject through directive observation and conduct on a spot, thus is likely to be useful in the fashion study. 3. It needs a historical access method for that purpose, If it applicate Weber's methodology, it will have the use of both meaning interpretation and explanation of cause and effect on the use of both meaning interpretation and explanation of cause and effect on the basis of realistic conditions (historical data), and would appear that the peculiar apportunity of mental (cultural) progressional process became definitive explanation. 4. It must be mad up of the discussion (which is) based on the durability of tradition and culture. It is undeniable that the discussion, which related to popular culture up to the present, showed the disconnectedness of the past tradition and culture, and naturally accepts it's connection to epistemology. The cultural study is a theory interested in what it brings about, what way it's organized and what way it's used. The research of the fashion's connection to popular culture is composed of such topic ; how fashion is produces, how it is consumed, and then, the proposition which is concerned in what meaning it produce is made up of. The regulation of the realm of this research will be to help a researcher explain where to begin and how to do it. Although this cultural study method is more or less quantitative, or despite the expense of the accuracy of statistical analysis, this means that such method of cultural research needs to give attention to both aspects of phenomena and basic problems.

When considering the actuality of the domestic foodservice industry that time it is appropriate, it sees. The foreign-brand goods which is introduced in the country are being executing in the 1ink of part management strategy. One of the most influential factor of domestic foodservice industry's management pressure is overspent management expenses, Does the namely expenses preparation effect reach which degree\ulcorner what kind of method can most decrease these expenses\ulcorner Doing grows the success and failure of the Korean foodservice industry controls result with the fact that it will operate with a big variable sees. The background which the domestic foodservice industry should introduce inevitably the outsiurcing system is to develop continuously nation foodservice industry in the way of cost curtailment of food-material, a labor cost curtailment with efficient application and synergic effect like specialty manpower utilization. The kindred competitive enterprises gradually concentrate management resource to the point ability from the present point of view which is increasing and a strategy position they secure, to prepare a competitive power, what sees it is important national industry must prepare a new paradigm. It is important to measure the result based on sales accomplishment in operation system dimension, and it is more important to appropriately apply regard of the evaluation measurement

  • The purpose of this literature review is to investigate what kinds of research have been done about scientific inquiry in terms of scientific argumentation in the classroom context from the upper elementary to the high school levels. First, science educators argued that there had not been differentiation between authentic scientific inquiry by scientists and school scientific inquiry by students in the classroom. This uncertainty of goals or definition of scientific inquiry has led to the problem or limitation of implementing scientific inquiry in the classroom. It was also pointed out that students' learning science as inquiry has been done without opportunities of argumentation to understand how scientific knowledge is constructed. Second, what is scientific argumentation, then? Researchers stated that scientific inquiry in the classroom cannot be guaranteed only through hands-on experimentation. Students can understand how scientific knowledge is constructed through their reasoning skills using opportunities of argumentation based on their procedural skills using opportunities of experimentation. Third, many researchers emphasized the social practices of small or whole group work for enhancing students' scientific reasoning skills through argumentations. Different role of leadership in groups and existence of teachers' roles are found to have potential in enhancing students' scientific reasoning skills to understand science as inquiry. Fourth, what is scientific reasoning? Scientific reasoning is defined as an ability to differentiate evidence or data from theory and coordinate them to construct their scientific knowledge based on their collection of data (Kuhn, 1989, 1992; Dunbar & Klahr, 1988, 1989; Reif & Larkin, 1991). Those researchers found that students skills in scientific reasoning are different from scientists. Fifth, for the purpose of enhancing students' scientific reasoning skills to understand how scientific knowledge is constructed, other researchers suggested that teachers' roles in scaffolding could help students develop those skills. Based on this literature review, it is important to find what kinds of generalizable teaching strategies teachers use for students scientific reasoning skills through scientific argumentation and investigate teachers' knowledge of scientific argumentation in the context of scientific inquiry. The relationship between teachers' knowledge and their teaching strategies and between teachers teaching strategies and students scientific reasoning skills can be found out if there is any.
