Popliteal artery injury in blunt trauma of knee joint is not common but poses high rate of amputation due to anatomical characteristics or delayed diagnosis and treatment. The aim of the present study is to review the authors' experiences with this condition and identify factors contributing to disability. We reviewed 7 cases of popliteal artery injury in trauma around knee. Injury mechanism, type of vessel damage, associated injuries, mangled extremity severity scores (MESS), ischemic time and additional treatments were analyzed. Tibial fracture, distal femoral fracture and serious soft tissue defect were combined. Mean MESS was 9.9 point and mean time of revascularization was 7.1 hours. Transfemoral amputation was performed in 2 cases due to vascular insufficiency and devastating infection, and 4 patients were able to walk without any support at the last follow up. Age, the severity of soft tissue injury, ischemic time and MESS are thought to be related to prognosis, and young patients with short ischemic time show best results, but authors experienced one exceptional case. We have to consider multiple factors related to the prognosis in popliteal artery injury with fractures around knee, and careful decision is needed regarding to early amputation.

This paper interrogates what a new point Schmitt shows concerning the problem of sovereignty in Hamlet or Hecuba in comparison with his Political Theology. Schmitt reveals his political stand on sovereignty through ‘political representation’ that connects the politics to the aesthetics in Hamlet or Hecuba since Hamlet is above all aesthetic work as play. He stresses the determining effect of political reality over the play as he links the story of Hamlet to the tragic family of James I and the religious conflicts of the Stuart dynasty. This leads to, on the one hand, supporting the myth of absolute sovereignty by elevating Hamlet to the transcendental and the exceptional status of sovereign. However, Schmitt’s intent over the absolute sovereignty is, on the other hand, demolished with the two shadows that he scrutinized through the couple of Hamlet and James I: first, the suspect that Gertrude(Mary Stuart) was involved in the murder of Hamlet(James I)’s father, and second, the century’s conflicts with religious reformation and civil war. The perils of sovereignty are manifested not only in these two, “the taboo of the Queen,” and “the Hamletization of the avenger.” It is most of all evidenced in Hamlet itself that subverts the unconditional sovereignty consistently. Hamlet’s selfreflective remarks likening the king to the beggar and the reality of Denmark succession prove that Hamlet’s political discourse is totally different from the politics that accentuates the divine sovereignty.

Under the existing law, an act included in medical practice by medical personnel seems to be irrelevant to whether the act concerned in the "Life World" is in the category of medical practice. In spite of the act having been done according to the custom for a long time, and generally done by individuals in the "Life World", these kinds of acts have been banned by law, because if these acts were done by the general individuals, it would be considered as harmful behavior to human life and body. And it is not sure that individuals know such a ban or notification. This cause a "Mistake of Law". Also it is happened if someone knows the existence of law but believes that his/her act is not included. For treating the problem of "Mistake of Law" of unlicensed medical act, in this study I inquired thoroughly into the category and regulation of unlicensed medical act, uncertainty of the Medical Services Law the first Section of Article 27, the prohibition of unlicensed medical act. The "Composition Condition" of the first Section of Article 27 of the Medical Services Law is not certain, it doesn't meet the "Doctrine of Clearance", and it cause the "Mistake of Law". Also it doesn't meet standardization of constitutional state. An exceptional decision of Pusan District Court, the debate about unlicensed medical practice, constitutional decision on unlicensed medical practice of the Constitutional Court of Republic of Korea and point of view of support of regulation. Also I examined the problem of "Mistake of Law" that the regulation of unlicensed medical practice has. I tried to solve uncertainty of "Composition Condition" and proposed a direction of regulation for solving the "Mistake of Law" and the use of existing law.

A point of view has been diversified where it has been put. We are living in the era that requests many standpoints to us to understand relations involved with me and my surrounding and it will speed up as the aspect has been changed so far. This phase is not exceptional to the design. Various spaces engaged in us have an immaterial phenomenon as composed by, so it is conceptualized to try the other way differentiated before. On the other hand, we can often meet examples of a literature scenario through conceptualizing an immaterial phenomenon as organized. Because of the difference between an individual's value and environment, it is criticized because of limitation to probe right and wrong of the objective feasibility. However, it is requested that this method needs to have an organized grammar in the interconnection broken of the standard of right and wrong in the science as well as goodness, evil and beauty in the morality. Nowadays a montage, which means the way to create objective by combining different points, is more multifariously applied in the generation of mixture asking various meanings and signifier and it's been widely extended. This study intends to pursue a new methodical approach focused on a characteristic of the montage and puts the goal on deduction for an expressive way of a montage specificity practically indicated at the shopping space through the space translation of the montage conception as well as plot of a movie. In conclusion, this study is how to be expressed of the montage expression method to understand.

To adapt to environmental changes and to maintain cellular homeostasis, microorganisms adjust the intracellular concentrations of biochemical compounds, including metal ions; these are essential for the catalytic function of many enzymes in cells, but excessive amounts of essential metals and heavy metals cause cellular damage. Metal-responsive transcriptional regulators play pivotal roles in metal uptake, pumping out, sequestration, and oxidation or reduction to a less toxic status via regulating the expression of the detoxification-related genes. The sensory and regulatory functions of the metalloregulators have made them as attractive biological parts for synthetic biology, and the exceptional sensitivity and selectivity of metalloregulators toward metal ions have been used in heavy metal biosensors to cope with prevalent heavy metal contamination. Due to their importance, substantial efforts have been made to characterize heavy metal-responsive transcriptional regulators and to develop heavy metal-sensing biosensors. In this review, we summarize the biochemical data for the two major metalloregulator families, SmtB/ArsR and MerR, to describe their metal-binding sites, specific chelating chemistry, and conformational changes. Based on our understanding of the regulatory mechanisms, previously developed metal biosensors are examined to point out their limitations, such as high background noise and a lack of well-characterized biological parts. We discuss several strategies to improve the functionality of the metal biosensors, such as reducing the background noise and amplifying the output signal. From the perspective of making heavy metal biosensors, we suggest that the characterization of novel metalloregulators and the fabrication of exquisitely designed genetic circuits will be required.

Purpose - This study examines the determinants of offer price and short-term and long-term performance of small and medium-sized enterprise(SME) IPO stocks listed on the KOSDAQ during the period from July 2007 to December 2016. Design/methodology/approach - The SME IPO samples are classified into three categories of regular listing, technology-based special listing, and listing by merger with special purpose acquisition company(SPAC), whose results are compared each other and compared to the result for the KOSDAQ listing of large firms. Findings - From the point of SME management which attempts to list its company on the KOSDAQ, the listing by merger with SPAC is the most unfavorable, and the underpricing phenomenon of the technology-based special listing is severe in the second place. By contrast, IPO stock investors can earn the largest abnormal return by purchasing the SPAC which succeeds the merger with unlisted firm, and the next abnormal returns are obtained in the order of the IPO stocks of technology-based special listing, regular listing of SMEs, and regular listing of large firms. However, it is interesting to observe that the net buying ratio of individual investors is relatively large for the IPO stocks of regular listing of SMEs and large firms, which exhibit the long-term under-performance. Research implications or Originality - This result implies that the exceptional listing system such as the technology-based special listing or the listing by merger with SPAC cost the SMEs which bypass the complicated procedure of the regular listing.

The practice of identifying the potential zones for mineral exploration in a speedy and low-cost method includes the use of satellite imagery analysis as a part of remote sensing techniques. It is challenging to explore the iron mineralization of a region through conventional methods which are a time-consuming process. The current study utilizes the Hyperion satellite imagery for mapping the iron mineralization and associated geological features in the Irikkur region, Kannur, Kerala. Along with the remote sensing results, the field study and laboratory-based analysis were conducted to retrieve the ground truth point and geochemical proportion to verify the iron ore mineralization. The MC simulation showed for shielding properties indicate an increase in the linear attenuation coefficient with raising the Fe₂O₃+SiO₂ concentrations in the investigated rocks where it is varied at 0.662 MeV in the range 0.190 cm^-1 - 0.222 cm^-1 with rising the Fe₂O₃+SiO₂ content from 57.86 wt% to 71.15 wt%. The analysis also revealed that when the γ-ray energy increased from 0.221 MeV to 2.506 MeV, sample 1 had the largest linear attenuation coefficient, ranging from 9.33 cm1 to 0.12 cm^-1. Charnockite rocks were found to have exceptional shielding qualities, making them an excellent natural choice for radiation shielding applications.

Purpose: The objective of this study was to determine the minimum number of teeth in the anterior dental arch that would yield accurate results for individual identification in forensic contexts. Materials and Methods: The study involved the analysis of 28 sets of 3-dimensional (3D) point cloud data, focused on the labial surface of the anterior teeth. These datasets were superimposed within each group in both genuine and imposter pairs. Group A incorporated data from the right to the left central incisor, group B from the right to the left lateral incisor, and group C from the right to the left canine. A comprehensive analysis was conducted, including the evaluation of root mean square error (RMSE) values and the distances resulting from the superimposition of dental arch segments. All analyses were conducted using CloudCompare version 2.12.4 (Telecom ParisTech and R&D, Kyiv, Ukraine). Results: The distances between genuine pairs in groups A, B, and C displayed an average range of 0.153 to 0.184mm. In contrast, distances for imposter pairs ranged from 0.338 to 0.522 mm. RMSE values for genuine pairs showed an average range of 0.166 to 0.177, whereas those for imposter pairs ranged from 0.424 to 0.638. A statistically significant difference was observed between the distances of genuine and imposter pairs(P<0.05). Conclusion: The exceptional performance observed for the labial surfaces of anterior teeth underscores their potential as a dependable criterion for accurate 3D dental identification. This was achieved by assessing a minimum of 4 teeth.

Robust magneto-telluric (MT) response function estimators are now in standard use in electromagnetic induction research. Properly devised and applied, these methods can reduce the influence of unusual data (outlier) in the response (electric field) variable, but often not sensitive to exceptional predictor (magnetic field) data, which are termed leverage points. A bounded influence estimator is described which simultaneously limits the influence of both outlier and leverage point, and has proven to consistently yield more reliable MT response function estimates than conventional robust approach. The bounded influence estimator combines a standard robust M-estimator with leverage weighting based on the statistics of the hat matrix diagonal, which is a standard statistical measure of unusual predictors. Further extensions to MT data analysis are proposed, including a establishment of data rejection criterion which minimize the influence of both electric and magnetic outlier in frequency domain based on statistical distribution of electromagnetic field. The rejection scheme made in this study seems to have an effective performance on eliminating extreme data, which is even not removed by BI estimator, in frequency domain. The effectiveness and advantage of these developments are illustrated using real MT data.
