Abstract With the continuous development of my country's sports industry, many drawbacks have appeared in traditional basketball teaching. This research mainly discusses the practical application of network multimedia courseware in college basketball teaching. Multimedia courseware teaching plan Multimedia courseware teaching plan consists of at least four parts: teaching content, teacher guidance, student learning and multimedia courseware. In the example of this study, FlashMX2004 is used to complete the multimedia courseware of basketball tactics basic teaching. The whole courseware is easy to embed in the webpage and is suitable for wireless network transmission on the Internet. Use the scanner to scan the text part into the computer, recognize it with Hanwang HWOCR5.0 recognition software, and edit it in Word. Use the video processor and audio processor of Kingsoft Hasee II to convert the VCD to the .avi video file format, use Windowsmoviemaker to edit and integrate the edited film, and finally import the required materials into Flash as needed to make the courseware . In order to ensure the correctness and effectiveness of the basic actions in the courseware, the empirical validity evaluation method is adopted, and the validity of the courseware content is tested. After the teaching experiment, in order to test the basic knowledge of basketball tactics and the theoretical knowledge of the two groups of students, a test of the theoretical knowledge of basketball tactics was carried out. The experimental group had 22 people with a score of 90 or more accounted for 27.5%, and the control group had 13 people with a score of 90 or more accounted for 16.5%. The results show that multimedia computer-assisted teaching has a positive role in cultivating students' interest in learning.

Right from the early days of the process industries, continuous efforts have been made to develop and improve measures for prevention and mitigation of dust explosions in these industries. Nevertheless this hazard continues to threaten industries that manufacture, use and/or handle powders and dusts of a wide range of combustible materials. To improve methods for predicting explosion development in real industrial plant has been one major challenge. Hence, during the last years comprehensive numerical simulation codes, for addressing this problem, have been developed. Progress has also been made in other areas, for example, ignition source prevention. The importance of adopting inherently safer process design, by building on firm knowledge in powder science and technology, and of systematic education/training of personnel, is also emphasized.

Concept Of Information

Based on the principle of fuzzy matter-element analysis, the concept of information entropy is introduced to establish a fuzzy matter-element evaluation method. This method is utilized to comprehensively evaluate the degree of debris flow. The classifications of debris flow are regarded as the objects of matter-element and their indexes for evaluation as well as the corresponding fuzzy values are used to construct the composite fuzzy matter-elements. By calculating the relevancy the comprehensive evaluation of debris flow can be carried out. This model is applied to analyze the degree of debris flow in the practical application. The application shows that the model is effective and practical.

Abstract Background The accuracy of computer-assisted biopsies at the lower jaw was compared to the accuracy of freehand biopsies. Methods Patients with a bony lesion of the lower jaw with an indication for biopsy were prospectively enrolled. Two customized bone models per patient were produced using a 3D printer. The models of the lower jaw were fitted into a phantom head model to simulate operation room conditions. Biopsies for the study group were taken by means of surgical guides and freehand biopsies were performed for the control group. Results The deviation of the biopsy axes from the planning was significantly less when using templates. It turned out to be 1.3 ± 0.6 mm for the biopsies with a surgical guide and 3.9 ± 1.1 mm for the freehand biopsies. Conclusions Surgical guides allow significantly higher accuracy of biopsies. The preliminary results are promising, but clinical evaluation is necessary.

Research Questions

In this article, we describe a practical implementation of a serious game to facilitate knowledge acquisition about renewable energy technologies among youngsters, using the game Serena Supergreen and the Broken Blade. We present the quest design and an evaluation study on the research questions: (a) Did youngsters who played the game have more knowledge about renewable energy technologies compared to those who did not play the game? (b) How did students perceive the game? (c) What did the students recall from the game 11 months after playing it? The study was conducted at a German secondary school ( n = 82). Youngsters who played the game had more knowledge on renewable energy technologies compared to the control group ( n = 31). In a second round of data collection, 11 months after playing, a majority of students still remembered the game quests. Our results indicate that serious games are a promising approach for introducing basic knowledge about renewable energy technologies.

The Impact

Objective This study aimed to evaluate the impact of the dietary supplement of Moringa oleifera leaves (MOL) on semen quality and characteristics in rabbits. Methods Eighteen (n=18) breeding bucks of New Zealand white, of similar age group, were used for the study. Three feeding regimes, (i) 100% commercial rabbit pellets (CRP)-Group I (ii) 90% CRP + 10% fresh MOL on a dry matter (DM) basis – Group II and (iii) 80% CRP + 20% fresh MOL on a DM basis – Group III, were adopted and the trial continued for 21 days. After adaptation to the diet, semen was collected from each buck and subjected to evaluation using a computer-assisted semen analyser. Results In Group III, the sperm count, normal sperm morphology, and sperm motility increased (52.0%) in comparison with the control (Group I; 50.1%). The inclusion of 20% Moringa oliefera in the diet (Group III) caused a significant increase (P<0.05) in semen concentration (Control =136.2 M/mL; Group III=297.2 M/mL). There was no significant difference (P>0.05) in sperm motility and semen volume among the groups. Conclusion The results suggest that supplementing commercial rabbit pellets with 20% fresh Moringa oliefera leaves on a DM basis can improve the quality and characteristics of semen in breeding bucks.

PURPOSE: To compare body weight and length, heart weight and length, heart-to-body weight ratio, glycemia, and morphometric cellular data of offspring of diabetic rats (ODR) and of normal rats (control). METHODS: Diabetes was induced in 3 pregnant Wistar rats, bearing 30 rats, on the 11th day after conception by intraperitoneal injection of 50 mg/kg of streptozotocin. Six normal pregnant Wistar rats, bearing 50 rats, made up the control group. Morphometric data were obtained using a scale for the weight, length, heart and body measurements. Morphometric cellular data were obtained by a computer assisted method applied to the measurements of myocytes. Statistical analysis utilized Student's t-test, ANOVA and Levene test. RESULTS: Control offspring had greater mean body weight and length than offspring of diabetic rats (p < 0.001). Heart weight and length and heart-to-body ratios of newborn rats differed between groups at birth (p < 0.001), but showed no difference at 21 days. Mean nuclei area and perimetric value of the myocytes decrees throughout the first 21 days of life (p < 0.01) in the diabetic group. CONCLUSIONS: Heart hypertrophy on the offspring of diabetic rats at birth was demonstrated by the significant difference between the groups. After the eleventh day, no difference was found, which confirmed regression of cardiomegaly. The significant difference between the first and the 21th day of life, for nuclei area feature, demonstrate regression of cardiac hypertrophy in the offspring of diabetic rats.

Purpose. To evaluate differences of Achilles tendon (AT) hardness and morphology between asymptomatic tendons in patients with acute AT ruptures on the contralateral side and asymptomatic tendons in healthy people by using computer-assisted quantification on axial-strain sonoelastography (ASE). Methods. The study consisted of 33 asymptomatic tendons in 33 patients (study group) and 34 tendons in 19 healthy volunteers (control group). All the tendons were examined by both ASE and conventional ultrasound. Computer-assisted quantification on ASE was applied to extract hardness variables, including the mean (Hmean), 20th percentile (H20), median (H50) and skewness (Hsk) of the hardness within tendon, and the ratio of the mean hardness within tendon to that outside tendon (Hratio) and three morphological variables: the thickness (THK), cross-sectional area, and eccentricity (ECC) of tendons. Results. The Hmean, Hsk, H20, H50, and Hratio in the proximal third of the tendon body in study group were significantly smaller than those in control group (Hmean: 0.43±0.09 vs 0.50±0.07, p=0.001; Hsk: -0.53±0.51 vs -1.09±0.51, p<0.001; H20: 0.31±0.10 vs 0.40±0.10, p=0.001; H50: 0.45±0.10 vs 0.53±0.08, p<0.001; Hratio: 1.01±0.25 vs 1.20±0.23, p=0.003). The THK and cross-sectional area of tendons in the study group were larger than those in the control group (p<0.05). Conclusions. As a quantitative objective method, the computer-assisted ASE reveals that the asymptomatic ATs contralateral to acute rupture are softer than those of healthy control group at the proximal third and the asymptomatic tendons in people with rupture history are thicker, larger, and rounder than those of normal volunteers especially at the middle and distal thirds of AT body.

Introduction. The endonasal mucosal or anatomic pathologies could lead to poor functional results and dissatisfaction after rhinoplasty. Although computed tomography (CT) scan has become an integral part of the diagnostic paradigm for patients with pathologies of the paranasal sinuses, the use of CT scan for preoperative evaluation of patients seeking rhinoplasty is up for debate. Our aim in this study was to compare the efficacy of CT scan in diagnosing nasal pathologies with other evaluating tools in patients undergoing rhinoplasty. Design. In this randomized controlled trial study, 74 consecutive patients seeking cosmetic rhinoplasty referred to otorhinolaryngology clinic were randomly assigned into three groups based on the perioperative evaluation method: the CT group, the nasal endoscopy group, and the control group (anterior rhinoscopy only). Surgical planning was made according to perioperative findings, and the identified endonasal pathologies were corrected during the surgery. The functional and aesthetic outcomes of the rhinoplasty were assessed by Nasal Obstruction Symptom Evaluation (NOSE), Rhinoplasty Outcome Evaluation (ROE), and the Visual Analogue Scale (VAS) tools before surgery and at 12-month follow-up. Results. All outcome measures improved significantly in either group toward one year after rhinoplasty (all with p value <0.05). Subjects in the CT group demonstrated greater improvement in the NOSE, VAS, and ROE compared to other two groups (NOSE: p value = 0.17; VAS: p value = 0.024; ROE: p value = 0.042). Conclusions. According to our study, perioperative CT is associated with greater patients’ satisfaction and quality of life after rhinoplasty compared to either nasal endoscopy or anterior rhinoscopy. A preoperative CT scan may improve the outcomes of rhinoplasty.
