On the Reconstruction of Teachers’Role of Business English Reading Classroom Teaching Based on Literature Circle

Business English reading teaching under the mode of“literature circles”focuses on cultivating students’autonomy in reading,group cooperation,and the exchange of ideas among group members.In this teaching mode,teachers are no longer the masters of the reading classroom,but the helpers,participants,and researchers in the process of students’reading.The reconstruction of teachers’role can promote the benign development of relationship not only between teachers and students,but also between students and students,inject new impetus and vitality into the classroom,and improve students’reading literacy.

Penile reconstruction

During the most recent years, a variety of new techniques of penile reconstruction have been described in the literature.

Conductivity reconstruction algorithms and numerical simulations for magneto–acousto–electrical tomography with piston transducer in scan mode

Conductivities tomography with the interactions of magnetic field, electrical field, and ultrasound field is presented in this paper. We utilize a beam of ultrasound in scanning mode instead of the traditional ultrasound field generated by point source. Many formulae for the reconstruction of conductivities are derived from the voltage signals detected by two electrodes arranged somewhere on tissue＇s surface. In a forward problem, the numerical solutions of ultrasound fields generated by the piston transducer are calculated using the angular spectrum method and its Green＇s function is designed approximately in far fields. In an inverse problems, the magneto-acousto-electrical voltage signals are proved to satisfy the wave equations if the voltage signals are extended to the whole region from the boundary locations of transducers. Thus the time-reversal method is applied to reconstructing the curl of the reciprocal current density. In addition, a least square iteration method of recovering conductivities from reciprocal current densities is discussed.

Asynchronous Secret Reconstruction and Its Application to the Threshold Cryptography

In Shamir’s(t,n) threshold of the secret sharing scheme, a secret is divided into n shares by a dealer and is shared among n shareholders in such a way that (a) the secret can be reconstructed when there are t or more than t shares;and (b) the secret cannot be obtained when there are fewer than t shares. In the secret reconstruction, participating users can be either legitimate shareholders or attackers. Shamir’s scheme only considers the situation when all participating users are legitimate shareholders. In this paper, we show that when there are more than t users participating and shares are released asynchronously in the secret reconstruction, an attacker can always release his share last. In such a way, after knowing t valid shares of legitimate shareholders, the attacker can obtain the secret and therefore, can successfully impersonate to be a legitimate shareholder without being detected. We propose a simple modification of Shamir’s scheme to fix this security problem. Threshold cryptography is a research of group-oriented applications based on the secret sharing scheme. We show that a similar security problem also exists in threshold cryptographic applications. We propose a modified scheme to fix this security problem as well.

Reconstruction of probabilistic S-N curves under fatigue life following lognormal distribution with given confidence

When the historic probabilistic S-N curves are given under special survival probability and confidence levels and there is no possible to re-test, fatigue reliability analysis at other levels can not be done except for the special levels. Therefore, the wide applied curves are expected. Monte Carlo reconstruction methods of the test data and the curves are investigated under fatigue life following lognormal distribution. To overcome the non-conservative assessment of existent man-made enlarging the sample size up to thousands, a simulation policy is employed to address the true production where the sample size is controlled less than 20 for material specimens, 10 for structural component specimens and the errors matching the statistical parameters are less than 5 percent. Availability and feasibility of the present methods have been indicated by the reconstruction practice of the test data and curves for 60Si2Mn high strength spring steel of railway industry.

Patient Satisfaction Index and Quality of Life Measurement with Breast-Q after Breast Reconstruction in a Plastic Surgery Center in Mexico

Introduction: Cancer is one of the most devastating pathologies to affect the breast. Mastectomy stigmas are associated with depression, body image dysmorphia, and decreasing quality of life. BREAST-Q is a PROM (Patient Reported Outcome Measures) that has proven useful in measuring satisfaction with breast reconstruction results from the patient’s point of view. Objectives: To measure the satisfaction index and improvement in quality of life after breast reconstruction for breast cancer sequelae in our hospital in the last 5 years. Materials and Methods: Descriptive Study that includes patients with Breast cancer diagnosis that underwent mastectomy and breast reconstruction (prosthesis or autologous tissue) in “Hospital Central Sur de Petroleos Mexicanos” (January 2015 to January 2020), whose satisfaction index was measured with BREAST-Q one year after reconstruction. Results: 153 patients were included in the analysis. Mean global satisfaction was 74 points. We observed a tendency towards higher psychosocial, sexual and appearance satisfaction in patients who underwent reconstruction with autologous tissue. The mean satisfaction with provided information was 64 points and with the medical team > 90 points. Conclusion: Breast reconstruction is associated to a high satisfaction index and quality of life improvement regardless of the technique. BREAST-Q proved to be useful in evaluating patient experience and it helped us identify areas of opportunity to improve our care.

Breast Reconstruction: Does It Worth to Start If the Patient Is Not Sure to Take All the Process Along?

Introduction: Breast cancer is the most common cancer in women worldwide, representing a major public health problem. There is still little information comparing the satisfaction of the patients who finished their process against the ones who start it but did not finish it. The aim of our retrospective study was to analyze the results in terms of satisfaction after one year of undergoing to complete breast reconstruction (CBR) vs incomplete breast reconstruction (IBR). Materials and Methods: Retrospective study of patients that underwent breast reconstruction (BR) surgery after mastectomy for breast cancer treatment. Performed at Hospital Central Sur de Alta Especialidad PEMEX in Mexico City, including patients from January 1, 2015 to January 01, 2020. Demographic baseline variables were included. BREAST-Q satisfaction questionnaires one year after the last reconstructive procedure were analyzed. Results: A total of 44 patients fulfilled the inclusion criteria. Of these 44 patients, 11 were included in the IBR group, and 33 patients in the CBR group. There were no statistically significant differences between the two groups in terms of age (IBR 56.09 vs CBR 53.06 years, p = 0.321);BMI (IBR 27.94 vs CBR 26.40, p = 0.253), time from mastectomy to first reconstructive procedure (IBR 22.8 vs CBR 31 months, p = 0.957), history of chemotherapy (IBR 27.3% vs CBR 33.3%, p = 0.709) and radiotherapy (IBR 54.5% vs CBR 42.4%, p = 0.484), additionally type of reconstruction, affected side or complication rate were not significantly different. Regarding postoperative satisfaction, only the second module of satisfaction with breasts displayed statistically significant differences, with a higher score in the CBR group (46.27 vs 52.27, p = 0.019). Other items explored didn’t show significant differences. Discussion: The data reported in this study suggest that regardless of whether the last stage of a BR is reached, the results in these settings can be very similar in terms of psychosocial well-being, sexual well-being, physical well-being regarding the chest area, with some degree of better perception of her breasts. Conclusion: This study suggests that the results in terms of satisfaction in BR after mastectomy for breast cancer are quite similar for patients who decide to take only the first reconstructive stage, compared with those that finished all the process along, this may be a valuable tool for decision making.

Evaluation of Drinking Water Pollution and Health Effects in Baghdad, Iraq

Contamination of water reserves by biological, chemical, and radiologic agents may affect the health of millions of residents in the Iraq as well as many others throughout the world. Fatal outbreaks of cholera struck several provinces of the country, including Baghdad. The United Nations Environment Programme (UNEP) also says air pollution, resulting from burning oil and aggravated by war, is cause for concern. The study area Baghdad has been divided into two parts: Central Baghdad and Outskirts of Baghdad (included in Baghdad but near the boundaries of Baghdad). The outskirts of Baghdad comprises of 4 cities: Al-Hussaniya located in northern part of Baghdad, Abu-Gurabe located in the western side of Baghdad, Jissr Diyala located in the eastern side of Baghdad and finally Al-Mahmodiya located in the southern side of Baghdad. These cities are in very poor situation in terms of water supply. The quality of water supplied is bad as no attention is given to WTP's in these places, which is also because of the fact that given the insecure war conditions, these areas are inaccessible. The sewage is thrown directly into the river because these areas do not have sewage treatment plants. In case of central Baghdad the water supply and sewerage network are broken in some places. Due to this there is mixing of water between the two networks. For this study we taking water supply samples and collect all the samples from WTPs and water supply network (houses, shops and different places). We made the analysis to parts first bacteriologies, second chlorine and after analysis these samples in lab we will give in our study numbers of fail samples, type of diseases and how many case during year 2007 in Baghdad City. Also in this study we will give Estimated Deaths from Water-Related Diseases 2010 to 2035.

Reconstructive surgery in Peyronie's disease: What's new?

Surgical treatment of Peyronie's disease(PD) is still a challenge and a gold standard approach does not exist; however the main goal is to straight penile shaft, and to restore penetrative and coital capacity. The less invasive approach aims to correct curvature without intervening directly on the fibrous plaque while the more complex "corporoplasty" applies specific geometric criteria and uses different autologous and heterologous grafts. Each approach has its pros and cons and decisionmaking should be tailored to the individual patient's expectations. Other surgical options include different use of patches to cover the tunica albuginea defect, with the choice depending on the surgeon's personal experience. Despite the wide range of autologous(buccal mucosa, vein, dermis, etc.) and heterologous grafts(bovine pericardium, swine intestinal submucosa, porcine dermis, etc.) none currently represents the real "gold standard" because the data are extremely variable and frequently not representative. Several factors seem to favor buccal mucosa grafts over inert biocompatible materials: as vital tissue, buccal mucosa tends to heal rapidly, immediately integrating with the surrounding albuginea tissue. This translates into a more rapid resumption of spontaneous erections(after 3/4 d) and sexual activity and into a reduced risk of curvature relapse and erectile dysfunction after surgery. Another advantage of the buccal mucosa graft is its low cost. In conclusion, despite the recent development of some exciting new surgical techniques we are still unable to deliver a definitive take-home message about reconstructive surgery in PD because the majority of the studies reported insufficient data. However, since it is clear that major outcomes, besides the cosmetic result, are the patient's and partner's satisfaction and the economic impact of each technique, we recommend they be included among the outcome assessment parameters in further
