Design-Oriented Thinking in STEM education: Exploring the Impact on Preschool Children's Twenty-First-Century Skills.

Given early childhood is a critical period for acquiring the twenty-first-century skills, the present study aimed to examine the effect of design-oriented STEM activities on the twenty-first-century skills of preschool children in line with the experimental design. A mixed factorial analysis of variance (ANOVA) of 3 (time: pre-test, post-test and persistence) × 2 (experimental group and control group) was used to test the hypothesis. The Bayesian factor analysis for mixed data was performed to identify the effects of design-oriented STEM education on differences between groups as well as within the group.

Trifecta Outcomes of Laparoscopic Partial Nephrectomy for T1a and T1b Renal Tumors: A Single-Center Experience in a Tertiary Care Institution.

To assess the effectiveness and safety of laparoscopic partial nephrectomy (LPN) in T1a and T1b renal tumors using "Trifecta" in partial nephrectomy and determine the predictive factors in respect to the criteria that constitute Trifecta. We retrospectively analyzed the data harvested from the patients who underwent LPN for T1a or T1b tumors. Preoperative, perioperative, and postoperative outcomes were evaluated and analyzed.

Robotic-assisted partial nephrectomy without using ureteral stent: a single center experience.

Objective: To share our results of robotic assisted partial nephrectomy (RAPN) we performed without using ureteral stent in a single center from Turkey.

Material And Methods: Medical records of consecutive 45 patients (34 men and 11 women) who underwent RAPN for kidney lesions between March 2011 and December 2014 were retrieved, and evaluated. All the procedures were performed by a transperitoneal approach without using ureteral stent prior to surgery.

980-Nm Diode Laser Vaporization versus Transurethral Resection of the Prostate for Benign Prostatic Hyperplasia: Randomized Controlled Study.

Purpose: We compared the effectiveness and complications of 980-nm diode laser vaporization and transurethral resection of the prostate (TURP) in patients with benign prostatic hyperplasia (BPH).

Materials And Methods: In total, 72 consecutive patients with BPH entered the study. All patients underwent general and urological evaluations.

Role of anterior prostatic fat pad dissection for extended lymphadenectomy in prostate cancer: a non-randomized study of 100 patients.

Purpose: To determine the incidence and significance of lymph nodes found in anterior prostatic fat pad (APFP) and to evaluate the risk factors for the lymph node presence at the APFP according to preoperative and postoperative characteristics during the robot-assisted radical prostatectomy (RARP).

Methods: Between January 2011 and December 2014, 100 consecutive patients (47-77) with clinically localized prostate cancer underwent APFP excision during RARP at a single institute. Extended pelvic lymph node dissection was also performed to moderate- and high-risk patients (86 patients).
