An Adaptive Learning Mode of "Public Psychology" Based on Creative Thinking with Virtual Simulation Technology

Due to the outbreak of COVID-19, the teaching of psychology in college has become especially important, posting higher requirements on the teaching content and purpose of the course of psychology. Nowadays, the traditional course of public psychology in college only focuses on the prevention and correction of psychological problems among college students, but educators ignore the importance of teaching students to understand psychological problems through relevant courses, making it impossible to achieve the expected effect of mental health education for students. Colleges should apply the notion of positive mental health education in the course of public psychology designed for college students. Students can better adapt to the society only when they have sound mental quality. According to requirement of “the zone of proximal development” a conceptual framework of the course was established in this study based on adaptation theory in which students are encouraged to think independently, as required by and an autonomous learning situation was created for students with psychological problems. At the same time, the education and teaching programming software named Scratch was adopted and integrated in the virtual simulated experimental teaching system of psychology. The integrated teaching system included the management of psychological teaching software, the monitoring of psychological experimental process, the query and analysis of psychological experimental data and the management of academic experimental resources, forming an integrated teaching environment with adaptive learning functions. In the end, the ant colony algorithm was used to mine a learning mode that is commensurate with the learner’s knowledge level, meets the learner’s resource preferences and satisfies the learner’s needs for learning activities, and this learning mode was identified as the best application mode for the learning of public psychology. It was revealed in practice that the adaptive learning mode of psychology based on virtual simulation technology can improve students’ learning initiative for the course of public psychology and increase their independent innovation ability.
Correlation of Sperm DNA Fragmentation Index With Seminal Plasma Biochemical Index and Semen Parameters in Infertile Men

In general, routine semen analysis makes only limited predictions about a man's reproductive potential and is not always able to explain why he is infertile. In fact, many male infertility cases are caused by sperm DNA defects ,which routine semen quality analyses fail to detect. The relationship between sperm DFI, sperm parameters and their diagnostic value were analyzed and evaluated by observing the seminal parameters of infertile patients without accessory gonadal infection. Specimens of 151 cases were collected from infertile patients who visited the male department of STD and reproductive specialty clinic of our hospital from August 2018 to September 2019. SCD test was performed to measure the DNA fragmentation in native. The routine semen analysis was performed with a semen quality detection system (CFT-920, Jiangsu Ruiqi Life Science & Tech Dev .Co.Ltd) and supporting reagents. Seminal plasma malondialdehyde (MDA), and total antioxidant capacity (TAC) were assessed. Fructose(Fru) 、a-glucosidase (a-glu), and zinc (Zn) levels are quantitatively detected by kehua-310, a fully automated biochemical tester provided by Nanjing Xindibio. According to DFI level, there were 31 cases in group I (DFI ≤ 15%), 81 cases in group II (15% < DFI < 30%), and 39 cases in group III (DFI ≥ 30%). Compared with group II, there were significant differences in sperm survival rate, PR% and Fru by non-parametric test (Z = -2.16 -2. 43. − 2. 20,respectively,P < 0. 05). There were significant differences in sperm survival rate and PR% between group I and group III (t = 4. 32, 4.25, respectively, P < 0.01). Compared with group III, there were significant differences in sperm survival rate and PR% by non-parametric test (Z= -3. 26, -3. 50, respectively). Sperm DFI was negatively correlated with sperm survival rate and PR%(R=-0.56,-0.46,P < 0.01). DFI was positively correlated with MDA content (R = 0.42, P < 0.01) and negatively correlated with TAC (r=-0.40, P < 0.01). There was no correlation with age ,abstinence days, semen volume, sperm concentration, percentage of normal form sperm, Fru, a-Glu, Zn (R = 0. 15, 0. 05,0.03,-0.03, -0.2, -0.16,- 0.20, 0.03, 0.15, p > 0.05). The survival rate and PR% of sperm decreased significantly with the increase of DFI level, antioxidant can decrease the rate of DNA fragmentation, antioxidant can decrease the rate of DNA fragmentation. Semen volume and sperm concentration were mainly related to the secretion volume of accessory gonads and total sperm count, but no correlation was found between them and DFI.
Proposed ITU-R Compatible Inter-Site and Inter-Sector Interference Models for LTE-Advanced Networks

Cellular network deployment with three sectors per site and a frequency reuse factor of one is key to supporting high data rate applications in LTE Advanced Networks. However, such configurations result in increased inter-cell interference. In this paper we model the effects of inter-cell interference on an LTE-Advanced network at two carrier frequencies. We consider two urban environments and four cell ranges. The effects of inter-cell interference are separated into inter-site interference and inter-sector interference. A site-specific 3D ray-tracing tool is used to model the communication channel between the base stations (serving and interfering links) and the user equipment terminals. The inter-site interference is first modelled in terms of its dominant interference proportion and then validated using previously reported field measurements recorded in London (U.K.). Secondly, the inter-site and inter-sector interference components are modelled as a function of user equipment relative position from the serving base stations. Our approach is compatible with the standardized ITU-R model and our proposal can easily be added to these international models. Our model requires no system layout for the interferers and reduces the required channel generation time by a factor of 12 compared with the system layout method.
Automatic analysis of passive constructions in Korean

The present study aims to explore the applicability of automatic analysis to L2-Korean learner corpora, with a special focus on learners’ use of a clause-level construction. For this purpose, we investigate L1-Mandarin L2-Korean learners’ written production of two passive construction types in Korean – suffixal and periphrastic – by devising a pattern-extraction process through NLP techniques. We focus on reporting how the passive constructions are identified and extracted from learner writing automatically, given language-specific features involving the passive. A total of 72 essays were analysed by adapting an existing pipeline (developed by Shin, forthcoming), with enhanced tokenisation and annotation through manual revision of the data. Results showed that our automatic pattern-finder identified more instances than manual extraction for the suffixal passive and yielded a perfect match with manual extraction for the periphrastic passive. Implications of the findings are discussed in regard to strengths and drawbacks of the automatic analysis of learner writing, with suggestions for improving currently available tools for learner corpus research in Korean.
Spatial Planning of Green Infrastructure for Mitigation and Adaptation to Climate Change at a Regional Scale

Green infrastructure has acquired greater importance in recent years in relation to climate change adaptation. Green infrastructure planning has been identified as a new and innovative means of land planning that can contribute to preventing the impacts of climate change. However, this has been explored more thoroughly in urban areas than at the regional scale. The present study proposes a methodology including multi-criteria evaluation techniques for assessing the ESS involved in the fight against climate change and for the spatial planning of multifunctional green infrastructure areas based on the results of this assessment. Application of the methodology for green infrastructure planning aimed at confronting climate change at landscape level in the region of Galicia (NW Spain) successfully delimited multifunctional green infrastructure zones. Results show that delimited zones have a higher provision potential for more ESS than protected natural areas and areas that are not part of the green infrastructure.
Exploring Axisymmetric Shape-Change’s Purposes and Allure for Ambient Display: 16 Potential Use Cases and a Two-Month Preliminary Study on Daily Notifications

In the last decade, HCI research has proposed promising technologies for shape-changing interfaces. The usefulness and the user experience of shape-change are, however, still to be explored and understood. This paper extends the understanding of the potential utility and usability of axisymmetric shape-change. First, we present 16 potential use cases for a cylindrical shape-changing display. Second, we present a two-month comparative field study in the workplace. Six participants had to shift energy consumption by using energy storage. To do so, they were notified about local energy forecasts. Compared with flat-screen animations, early results show that cylindrical shape-change animations keep a better attractiveness over time.
Los proyectos a favor de las provincias del Reino de Guatemala en las Cortes de Cádiz

This paper aims to analyze the projects sent to the Courts of Cádiz by the provinces of the Kingdom of Guatemala. It intends to discern the nuances of the theory about the search for autonomy from Spain used to interpret the actions regarding the projects carried out by representatives from the American colonies at those Courts. Since this is a theme that has hardly been researched, most data comes from archival sources treated thematically by means of a database. The findings have enabled a clearer understanding that the driving force behind these projects was not the search for autonomy from Spain, but rather an economically-driven struggle to gain power internally. The findings have also helped to answer why despite the fact that emancipation took place without bloodshed, the provinces split apart leading to the failure of the federal system.
Synthesis of ABC and CABAC Triphilic Block Copolymers by ATRP Combined with ‘Click’ Chemistry

ATRP using poly(propylene oxide) monofunctional macroinitiator was carried out with solketal methacrylate (SMA) and the non-reactive PPO having two N 3 terminal groups was removed by dissolution in an excess of n-hexane. The resulting azido terminated AB diblock copolymer was 'clicked' with an α-alkyne fluorinated compound, followed by acid hydrolysis of the SMA units, a triphilic ABC triblock copolymer was prepared. ATRP of SMA with a difunctional PPO macroinitiator to give ABA triblock copolymer was also carried out. The terminal Br was again exchanged with N 3 , 'clicked' with the α-alkyne fluorinated compound and likewise hydrolyzed to give a triphilic CABAC pentablock copolymer, i.e., hydrophilic, oleophilic, and fluorophilic blocks were combined.
Fuzzy-based reliable and secure cooperative spectrum sensing for the smart grid

Cognitive radio is a promising technology to solve the spectrum scarcity problem caused by inefficient utilization of radio spectrum bands. It allows secondary users to opportunistically access the underutilized spectrum bands assigned to licensed primary users. The local individual spectrum detection is inefficient, and cooperative spectrum sensing is employed to enhance spectrum detection accuracy. However, cooperative spectrum sensing opens up opportunities for new types of security attacks related to the cognitive cycle. One of these attacks is the spectrum sensing data falsification attack, where malicious secondary users send falsified sensing reports about spectrum availability to mislead the fusion center. This internal attack cannot be prevented using traditional cryptography mechanisms. To the best of our knowledge, none of the previous work has considered both unreliable communication environments and the spectrum sensing data falsification attack for cognitive radio based smart grid applications. This paper proposes a fuzzy inference system based on four conflicting descriptors. An attack model is formulated to determine the probability of detection for both honest and malicious secondary users. It considers four independent malicious secondary users’ attacking strategies of always yes, always no, random, and opposite attacks. The performance of the proposed fuzzy fusion system is simulated and compared with the conventional fusion rules of AND, OR, Majority, and the reliable fuzzy fusion that does not consider the secondary user’s sensing reputation. The results indicate that incorporating sensing reputation in the fusion center has enhanced the accuracy of spectrum detection and have prevented malicious secondary users from participating in the spectrum detection fusion
Immuno affinity purification combined with mass spectrometry detection for the monitoring of VEGF isoforms in patient tumor tissue

Vascular endothelial growth factor (VEGF) is a key mediator of tumor growth and metastasis. At least 7 isoforms of the protein exist due to differential splicing, but little is known about the biological activities of these different isoforms. We purified VEGF from resected human bronchial carcinoma tissue and normal bronchus by immuno affinity chromatography (IAC) and immuno capture (IC) on a ProteinChip® Array, identifying the isoforms by MS. Both methods proved to be useful for the analysis of protein isoforms, which are present in situ in tumor tissue. Different expression patterns of VEGF were demonstrated in tumor tissue compared to healthy tissue. The possibility to analyse VEGF protein isoforms in situ creates new opportunities to study the regulation of angiogenesis in healthy and malignant tissues.
Three combination value of extraction features on GLCM for detecting pothole and asphalt road

The rate of vehicle accidents in various regions is still high—accidents caused by many factors, such as driver negligence, vehicle damage, road damage, etc. However, transportation technology developed very rapidly, for example, a smart car. The smart car is land transportation that does not use humans as drivers but uses machines automatically. However, vehicle accidents are still possible because automatic machines do not have intelligence like humans to see all the obstacles in front of the vehicle. Obstacles can take many forms, one of them is road potholes. We propose a method for detecting road potholes using the Gray-Level Cooccurrence Matrix with three features and using the Support Vector Machine as a classification method. We analyze the combination of GLCM Contrast, Correlation, and Dissimilarity features. The results showed that the combination of Contrast and Dissimilarity features had the best accuracy of 92.033% with a computing time of 0.0704 seconds per frame.
3D Printing Technologies in Metallic Implants: A Thematic Review on the Techniques and Procedures

Additive manufacturing (AM) is among the most attractive methods to produce implants, the processes are very swift and it can be precisely controlled to meet patient’s requirement since they can be produced in exact shape, dimension, and even texture of different living tissues. Until now, lots of methods have emerged and used in this field with diverse characteristics. This review aims to comprehensively discuss 3D printing (3DP) technologies to manufacture metallic implants, especially on techniques and procedures. Various technologies based on their main properties are categorized, the effecting parameters are introduced, and the history of AM technology is briefly analyzed. Subsequently, the utilization of these AM-manufactured components in medicine along with their effectual variables is discussed, and special attention is paid on to the production of porous scaffolds, taking pore size, density, etc., into consideration. Finally, 3DP of the popular metallic systems in medical applications such as titanium, Ti6Al4V, cobalt-chromium alloys, and shape memory alloys are studied. In general, AM manufactured implants need to comply with important requirements such as biocompatibility, suitable mechanical properties (strength and elastic modulus), surface conditions, custom-built designs, fast production, etc. This review aims to introduce the AM technologies in implant applications and find new ways to design more sophisticated methods and compatible implants that mimic the desired tissue functions.
Clinical Efficacy and Rehabilitation of Microscopic “Over the Top” for Bilateral Decompression in Degenerative Lumbar Stenosis: A Retrospective Study

Background Recently, “over the top” (also called ULBD; microscopic unilateral laminotomy for bilateral decompression) is a less invasive technique for symptomatic degenerative lumbar spinal stenosis (LSS), and this minimally invasive surgical technique has demonstrated favorable therapeutic outcomes. However, the risk of postoperative complications remains controversial. Objective This study is aimed at determining the clinical efficacy and complication and rehabilitation of the microscopic “over the top” for degenerative LSS in geriatric patients. Study Design. This was a retrospective study. Setting. All data were obtained from the People's Hospital of a University. Methods A retrospective analysis of 39 consecutive elderly patients treated for LSS by microscopic “over the top” between January 2016 and January 2018 was performed. A postoperative rehabilitation program for geriatric patients with restricted weight-bearing was instituted after the microscopic “over the top” treatment. Estimated blood loss, duration of operation, length of hospitalization, and total complications were also evaluated. The CT and MRI examinations of the lumbar spine were collected to evaluate the completeness of the nerve decompression. Clinical data were assessed at 6 months and 12 months after operation utilizing the visual analog scale (VAS), Oswestry Disability Index (ODI), and 36-Item Short-Form Health Survey (SF-36). Preoperative comorbidities, complications, and revision surgery were also recorded. Results We enrolled a total of 39 degenerative LSS patients (27 male and 12 female patients, mean age of 75.8 ± 9.2 years). Twenty patients had one-level of degenerative LSS; thirteen patients had two-level of LSS; six patients had three-level of LSS. The average follow-up time in our study was 14.6 ± 7.8 months (range, 6-24 months). The overall complication rate was 10.2% (4/39), and the reoperation rates at one year were 2.5% (1/39). VAS back and leg pain score at 6 months were decreased to 1.8 ± 0.7 and 1.4 ± 0.6, respectively, and remained at 1.9 ± 0.3 and 1.2 ± 0.2 at 12 months, respectively. ODI scores improved significantly from 32.26 ± 6.82 to 11.44 ± 2.50 at 6 months and 10.56 ± 2.29 at 12 months. 36-Item Short-Form Health Survey scores revealed a significant improvement throughout follow-up. Postoperative complications included dural tear (n = 2), neurologic deficit (n = 1), and reoperation (n = 1). No infections or hematomas were reported. Limitation. Multicenter research is recommended to confirm our results and investigate the factors related to clinical and radiographic results. Conclusions Microscopic “over the top” technique is a safe, effective option in the therapy of degenerative LSS and obtained satisfactory functional outcomes when coupled with aggressive rehabilitation, with a long recurrence-free recovery.
Pelvic local recurrence as first relapse predicts prognosis for clinical stage II/III lower rectal cancer: A clinicopathological investigation

The present study investigated the association between the mode of tumor recurrence and prognosis in 123 patients with clinical stage II/III rectal cancer. In the past 10 years, patients received systemic chemotherapy following radical (R0, with no macroscopic residual tumor lesions) resection using total or tumor-specific mesorectal excision. Patients with rectosigmoid cancer and T4 + chemoradiation therapy were excluded from the present study. The 5-year relapse-free survival rate (5Y-RFS), 5-year overall survival rate (5Y-OS), and associations between early post-operative complications, recurrence mode and prognosis, as well as the 5Y-OS of patients with relapsed cancer, were calculated. The overall 5Y-RFS and 5Y-OS were 71.4 and 83.5%, respectively, and the overall recurrence rate was 22.8% (28/123 patients). Among relapses, remote metastases were observed in 17/123 patients (13.8%): The lung in 8 patients (6.5%), the liver in 5 patients (4.1%) and elsewhere in 4 patients (3.3%). A total of 11 patients (8.9%) had pelvic local recurrence as the first relapse, which was located anterior to the sacrum in 7 patients (5.7%), at the anastomosis site in 2 patients (1.6%), and in the inner pelvis in 2 patients (1.6%). Among relapsed patients, the 5Y-OS was 69.3% in those with distant metastases and 27.3% in those with local relapse (P=0.02; no significant differences in patient demographics). The results indicated that advanced rectal cancer and control of pelvic local recurrence are manageable by R0 resection and postoperative chemotherapy. However, for patients whose initial relapse was pelvic local recurrence, the relapsed tumor initiated a new metastatic cascade to organs, such as the lung and liver, and affected prognosis.
Horizontal Internal Gravity Waves in the Mars Upper Atmosphere From MAVEN ACC and NGIMS Measurements

Internal gravity waves (IGWs) play an important role in the planetary atmospheres, which transfer energy and momentum from the lower layers to the upper atmosphere. However, the IGW perturbations and behaviors are not clear in the Mars upper atmosphere, particularly for the horizontal internal gravity waves (hIGWs). In this study, the hIGWs in the upper atmosphere of Mars are estimated and investigated for the first time using both accelerometer (ACC)‐derived mass density and Neutral Gas and Ion Mass Spectrometer‐measured neutral density from Mars Atmosphere and Volatile EvolutioN (MAVEN) mission. The results show that the amplitudes of hIGWs variations are significantly affected by the dust storms and increase with the altitudes. The larger amplitudes are triggered in Martian Year (MY) 34 during a global dust event. The characteristics of Ar and CO2 hIGWs variations are similar. Furthermore, the trend of the CO perturbations seems to follow the CO2. However, the dust storms play little role in shaping hIGWs of atomic O. The hIGWs show the stable waveform with the increasing altitudes.
Optically induced and erased birefringence and dichroism in azoaromatic polymers

Dichroism and birefringence are shown to be optically induced and erased in high‐glass‐transition azoaromatic polymers. The resulting polarization information is easily detected and exhibits long‐term stability. This optically induced reorientation of the azoaromatic molecules will have wide applications in image recording and in electro‐optical devices.
