Statistics is the science of data. As the foundation of scientific knowledge, data refers to evidentiary facts from the nature of reality by human action, observation, or experiment. Clinicians should be aware of the conditions of good data to support the validity of clinical modalities in reading scientific articles, one of the resources to revise or update their clinical knowledge and skills. The cause-effect link between clinical modality and outcome is ascertained as pattern statistic. The uniformity of nature guarantees the recurrence of data as the basic scientific evidence. Variation statistics are examined for patterns of recurrence. This provides information on the probability of recurrence of the cause-effect phenomenon. Multiple causal factors of natural phenomenon need a counterproof of absence in terms of the control group. A pattern of relation between a causal factor and an effect becomes recognizable, and thus, should be estimated as relation statistic. The type and meaning of each relation statistic should be well-understood. A study regarding a sample from the population of wide variations require clinicians to be aware of error statistics due to random chance. Incomplete human sense, coarse measurement instrument, and preconceived idea as a hypothesis that tends to bias the research, which gives rise to the necessity of keen critical independent mind with regard to the reported data.

Colin Rowe was an important historian, theorist and critic in Modern architecture. His significance in Modern architectural history lies in not only historiography which has changed our view of Modernism but deep theoretical involvement in practice. This study is a critical review and analysis on his formalist approach in Architecture. With a view that his position of formalist has indispensible relationship with liberalism from K. Popper's critical rationalism, this study try to show how his philosophical background has an influence upon his way of seeing architecture, history, form, urbanism, and meaning, etc. And this study also try to explain why the principle of architecture as an autonomous discipline which is the main point of view in Rowe's criticism has been so successful and influential. This study also explain what is the possibility and limitation of Rowe's formalist approach and way of reading buildings. His intelligent way of formal analysis can give us new understandings of how the form generates and the process of design goes on. Furthermore it guide us a new horizon of architecture as a language game. Since his early writings showed both side of formalist approach in architecture and it didn't changed a lot. We can understand his 'Collage City' was a his final answer to his formalist way of making architecture and urbanism. we can estemate it as a utopia without utopianism and an ideology without ideological color.

Radiologists and trauma surgeons should monitor for early killers among patients with thoracic trauma, such as tension pneumothorax, tracheobronchial injuries, flail chest, aortic injury, mediastinal hematomas, and severe pulmonary parenchymal injury. With the advent of cutting-edge technology, rapid volumetric computed tomography of the chest has become the most definitive diagnostic tool for establishing or excluding thoracic trauma. With the notion of "time is life" at emergency settings, radiologists must find ways to shorten the turnaround time of reports. One way to interpret chest findings is to use a systemic approach, as advocated in this study. Our interpretation of chest findings for thoracic trauma follows the acronym "ABC-Please" in which "A" stands for abnormal air, "B" stands for abnormal bones, "C" stands for abnormal cardiovascular system, and "P" in "Please" stands for abnormal pulmonary parenchyma and vessels. In the future, utilizing an artificial intelligence software can be an alternative, which can highlight significant findings as "warm zones" on the heatmap and can re-prioritize important examinations at the top of the reading list for radiologists to expedite the final reports.

The research objective of this study is to analyze the aspects of small group decision-making process based on reading news reports in the context of the socio-scientific issues (SSI) activity related to climate change. Twenty-two high school students from Gyeonggi Province, South Korea, were asked to read two news reports on the UN climate change conferences and take a stance on joining the Paris Agreement both as an individual and as a small group. The news reports were analyzed in terms of genre, discourse, and style adapting the critical discourse analysis (CDA) and the decision-making processes of the small groups were examined on recognizing a problem and evaluating alternatives and decisions. The results from analyzing the news reports denoted that the Paris agreement is not only related to finding ideal solutions to climate change, but rather, connected to political or economic interests and power relationship. In the stage of recognizing a problem, meanwhile, different frames which students recognize the Paris agreement and discourses in the foreground of the news reports were the critical causes in terms of identifying the problem. In the stage of evaluating alternatives and decisions, the equity and fairness were the criteria for the small group discussions. This study implies the necessity of the scientific literacy instruction to develop the ability to critical reading in the context of the SSI.

Genomic analysis of a hyperthermophilic archaeon, Thermococcus onnurineus NA1 [1], revealed the presence of an open reading frame consisting of 1,377 bp similar to ${\alpha}$-amylases from Thermococcales, encoding a 458-residue polypeptide containing a putative 25-residue signal peptide. The mature form of the ${\alpha}$-amylase was cloned and the recombinant enzyme was characterized. The optimum activity of the enzyme occurred at $80^{\circ}C$ and pH 5.5. The enzyme showed a liquefying activity, hydrolyzing maltooligosaccharides, amylopectin, and starch to produce mainly maltose (G2) to maltoheptaose (G7), but not pullulan and cyclodextrin. Surprisingly, the enzyme was not highly thermostable, with half-life ($t_{1/2}$) values of 10 min at $90^{\circ}C$, despite the high similarity to ${\alpha}$-amylases from Pyrococcus. Factors affecting the thermostability were considered to enhance the thermo stability. The presence of $Ca^{2+}$ seemed to be critical, significantly changing $t_{1/2}$ at $90^{\circ}C$ to 153 min by the addition of 0.5 mM $Ca^{2+}$. On the other hand, the thermostability was not enhanced by the addition of $Zn^{2+}$ or other divalent metals, irrespective of the concentration. The mutagenetic study showed that the recovery of zinc-binding residues (His175 and Cys189) enhanced the thermo stability, indicating that the residues involved in metal binding is very critical for the thermostability.

This essay examines Edward Said's Culture and Imperialism focusing on the concepts of 'culture,' 'empire,' and 'nation'. The approach is critical, theoretical, and historical rather than explicatory. Consequently, the range of the essay is not limited to Said's own explanation and argument about Western imperialism and its culture presented in the book. In doing this, this essay finally purposes to be a discursive resistance to the current global empire, the United States, via a critical reading of Said's work. Said's notion of culture is set upon to disclose the function of culture as an apparatus of ideological consent of the dominated to the dominant. When applied to imperial practice, Western culture functions to subject the colonized to the colonizer. Said's geographical approach to imperialism complements the historical understanding of imperialism. Imperialism is not only the practice of Western-centered historicism but also the spatially mutual interaction between the West and the rest of the world. Along with European imperialism, Said poses the current global empire of the United States as his main target of criticism. Said's problem is that he takes the United States as a nation-state. When examined, the United States is not a nation-state, but today's empire. The empire in the appearance of the nation-state United States does not work for the interest of the American nation, that is, the American people. The empire is the transnational and postnational political and economic institution that works for the interest of global capital. In order to resist the current global empire, this essay suggests that the building or restoration of nation-states with its basic principle of people's sovereignty is in need.

Due to the plethora of political, economic, and social challenges experienced on a global scale in the 21st century, students need to be concerned with more than their immediate surroundings (Johnson, 2005). When implemented in an educational setting, topics encompassing social justice may provide students with the confidence and skills to become "reflective, moral, caring, and active citizens in a troubled world" (Banks and Banks, 2009, p.5). The purpose of this article was to provide examples of undergraduate lessons focused on sweatshop conditions within three time periods of United States history that incorporate social justice into the course curriculum. By implementing social justice lessons into the curriculum, students can engage in critical reading, writing, and thinking about injustices faced by society. Girded with knowledge of past oppression within the apparel industry, students may become actively engaged in challenging social injustices in our world.

There is no single or simple answer for effective communication between laboratory technician and clinical dentist. Love-hate could be used to describe the relationship between dentists and their labs. Great lab work can make a dentists life much easier and can result in getting many referrals. However, if the lab work is not up to par and/or late, it can add stress and agony to a dentists practice. Also the opposition is right. If the preparations are calibrated, the impressions clear, and the bite registrations accurate, most labs can do their work reasonably well. Unfortunately, many cases received by labs are barely adequate, especially when it comes to reading margins, which are frequently created by the imagination of the person trimming the dies. In other words, both dentists and lab technicians need to be able to understand how each party operates so that solutions to problems can be found. Effective communication with the laboratory is critical if any degree of success is desired.

The suspension is a structure that supports reading, writing head in information storage device. In order to develop the information storage device of high track density, it is necessary to study about the suspension. To satisfy operation condition of information storage device, the suspension shape is very important since it correlates to dynamic characteristics. Therefore, it is necessary to analyze the dynamic characteristics by using finite element analysis and to optimize the suspension of information storage device using size optimization and topology optimization. The suspension has various modes according to different kinds of frequency bandwidth. Sway mode and second torsion mode are especially critical among them. In this paper, we investigated method to improve bandwidth of sway and second torsion mode of HDD and ODD suspension by using size optimization and topology optimization.
