The e-character education (e-CE) approach refers to systems of ethics education that pertain specifically to cyberspace. This exploratory study used a survey to collect 2495 teachers\' responses regarding virtues important to e-CE. Furthermore, in order to identify the teaching concerns associated with these most important virtues, this study used two focus groups that involved interviews with 16 teachers and Internet experts, as well as a content analysis of 92 posts from 72 teachers in an online course regarding ethical behavior in the context of Internet activity. The results of this study show that e-CE virtues considered important by teachers include law abidance, respect, self-discipline and sharing. Teaching-related concerns of these virtues have also been discussed. The results serve as a foundation and guide for the promotion of e-CE curriculum development and implementation.

BACKGROUND: Single-incision laparoscopic cholecystectomy (SILC) has been shown to be safe for uncomplicated gallbladder diseases. Routinely applying SILC is debatable. METHODS: Two hundred SILCs were performed with single-incision multiple-port longitudinal-array and self-camera techniques. RESULTS: Eighty-eight (44%) procedures were scheduled for complicated diseases. The routine group had a higher comorbidity rate, a lower preoperative endoscopic retrograde cholangiopancreatography rate, a higher intraoperative cholangiography rate, a higher proportion of complicated gallbladder diseases, shorter operative time, more intraoperative blood loss, and lower postoperative pethidine dose than the selective group (the first 73 patients). The conversion and complication rates showed no statistical difference. It took fewer cases but longer time to pass the learning phase of SILC for complicated gallbladder diseases. The multivariate analysis showed that male sex and complicated gallbladder diseases were associated with a higher procedure conversion rate, and increased patient age was related to a higher complication rate. CONCLUSIONS: Routine SILC for benign gallbladder diseases is feasible in the experienced phase. Practicing SILC for uncomplicated gallbladder diseases helps to achieve competence in this technique for complicated diseases. (C) 2015 Elsevier Inc. All rights reserved.

Single-incision laparoscopic surgery developed rapidly in recent years. We introduce an innovative technique: single-incision laparoscopic common bile duct exploration (SILCBDE) with conventional instruments. A retrospective comparison between SILCBDE and standard laparoscopic common bile duct exploration (LCBDE) was analyzed. Thirty-four patients who underwent LCBDE for choledocholithiasis in a period of 17 months were enrolled. Seventeen standard LCBDEs and 17 SILCBDEs were attempted. Simultaneous cholecystectomies were performed. The stone clearance rate was 94.1 % (16 patients) in the standard LCBDE group and 100 % in the SILCBDE group. There was no statistical difference in demographic distribution, clinical presentations, and operative results between the two groups, except the SILCBDE group had a higher rate of acute cholecystitis than the standard LCBDE group (76.5 vs. 35.3 %; p < 0.05). One procedure (5.9 %) in the SILCBDE group was converted to a four-incision transcystic LCBDE. The complication rate was 11.8 % (two patients) in the standard LCBDE group and 5.9 % (one patient) in the SILCBDE group. The average follow-up period was 4.2 months. SILCBDE is as safe and efficacious as standard LCBDE in experienced hands. Choledochoscope manipulation and bile duct repair are the key skills. Long-term follow-up and further prospective randomized trials are anticipated.

AIM: To compare the clinical outcome of single-incision laparoscopic cholecystectomy (SILC) and three-incision laparoscopic cholecystectomy (3ILC) for acute cholecystitis. METHODS: From July 2009 to September 2012, 136 patients underwent SILC or 3ILC for acute cholecystitis at a tertiary referral hospital. One experienced surgeon performed every procedure using 5 or 10 mm 30-degree laparoscopes, straight instruments, and conventional ports. Five patients with perforated gallbladder and diffuse peritonitis and 23 patients with mild acute cholecystitis were excluded. The remaining 108 patients were divided into complicated and uncomplicated groups according to pathologic findings. Patient demog-raphy, clinical data, operative results and complications were recorded and analyzed. RESULTS: Fifty patients with gangrenous cholecystitis, gallbladder empyema, or hydrops were classified as the complicated group, and 58 patients with acute cholecystitis were classified as the uncomplicated group. Twenty-three (46.0%) of the patients in the complicated group (n = 50) and 39 (67.2%) of the patients in the uncomplicated group (n = 58) underwent SILC; all others underwent 3ILC. The postoperative length of hospital stay (PLOS) was significantly shorter in the SILC subgroups than the 3ILC subgroups (3.5 +/- 1.1 d vs 4.6 +/- 1.3 d, P < 0.01 in the complicated group; 2.9 +/- 1.1 d vs 3.7 +/- 1.4 d, P < 0.05 in the uncomplicated group). The maximum body temperature recorded at day 1 and at day 2 following the procedure was lower in the SILC subgroups, but the difference reached statistical significance only in the uncomplicated group (37.41 +/- 0.56. vs 37.80 +/- 0.72., P < 0.05 on postoperative day 1; 37.10 +/- 0.43. vs 37.57 +/- 0.54., P < 0.01 on postoperative day 2). The operative time, estimated blood loss, postoperative narcotic use, total length of hospital stay, conversion rates, and complication rates were similar in both SILC and 3ILC subgroups. The complicated group had longer operative time (122.2 +/- 35.0 min vs 106.6 +/- 43.6 min, P < 0.05), longer PLOS (4.1 +/- 1.3 d vs 3.2 +/- 1.2 d, P < 0.001), and higher conversion rates (36.0% vs 19.0%, P < 0.05) compared with the uncomplicated group. CONCLUSION: SILC is safe and efficacious for patients with acute cholecystitis. The main benefit is a faster recovery than that achieved with 3ILC. (C) 2013 Baishideng Publishing Group Co., Limited.

Given the importance of cultivating users' positive behaviors in cyberspace, this study presents a comprehensive vision of how to address important virtues that might foster Taiwanese adolescents' positive behaviors in cyberspace. In this study, we constructed an instrument-the Cyber Virtues Scale (CVS)-for measuring the underlying dimensions of Taiwanese adolescents' virtuous behaviors in online settings. Research data were gathered from 607 elementary and junior high school students in different Taiwan's geographic areas. The CVS model has been empirically validated via exploratory factor analysis. The final version of the CVS consists of 5 core virtues in cyberspace: interpersonal interaction, knowledge accumulation, social justice, information sharing and self-discipline. These results will also strengthen the digital generation by cultivating their positive behaviors in cyberspace.

With the expansion of digital content, academic integrity has been facing the growing threat of cyber-plagiarism. In the present research, we address young Taiwanese students\' perceptions of cyber-plagiarism. Our research included two related studies: in study 1, we collected data through a national survey on a probability sample of 41,911 (4th-12th graders) and analyzed the prevalence and alternative thinking about cyber plagiarism among these students; in study 2, we collected 113 young students\' anonymous questionnaires inquiring into the reasoning that the students applied to their own use of online resources for homework. The results of our research show that the prevalence of frequent copy-and-paste students was less than 3% of the surveyed 4th-12th graders in Taiwan. Moreover, we have found that copy-and-paste practices were more prevalent among the 10th and 12th graders than among students in the other grades, and that more male students than female students engaged in copy-and-paste behavior. We have also found that these students\' concept and their ways of using Internet information properly seem incorrect. We suggest that educators implement copy-and-paste prevention curriculum throughout elementary, junior high, and high schools. We offer teaching advice for the prevention of cyber plagiarism, encouraging educators to teach students appropriate ways to resolve copy-and-paste problems. (C) 2015 Elsevier Ltd.
