ABSTRACT
Introduction:
Simulators (Lap trainers) are essential for training surgeons on the basic and advanced laparoscopic skills. However, it is not available in most of our hospitals. The high cost and the difficulty in attending hands on training courses for the majority of surgeons in developing countries is reflected on the level of practice and on the patient's safety.
In this study, there is an introduction and evaluation of a novel and cheap pelvitrainer, which could be an aid for training on laparoscopy in developing countries, as well as a brief account on the importance of having a structured training program. Key words: pelvitrainer, laparoscopic training.
Materials & Methods:
Thirty (n=30) general surgical residents, years 1 & 2 in training, at Ain Shams University hospital, Cairo, Egypt, were enrolled in a prospective, randomized, controlled, double blind study. In the first -study- group (n=15), residents were randomly assigned to have one hour training using the new pelvitrainer for 3 consecutive days. The training exercises were composed of three levels of difficulty, starting with pick & place exercise, then precision cutting and lastly laparoscopic suturing. Following this, their ability to perform efficient laparoscopic dissection of the gall bladder bed during laparoscopic cholecystectomy in the operating theater under supervision, was assessed by an independent observer who was a surgery consultant. Following this, the trainees were given questionnaires to evaluate the process.
On the other hand, concurrently, a comparable number of residents -controls- (n=15), who have not been trained on the pelvitrainer, were also evaluated during performing the same operative procedure, under supervision. The results of the evaluations and questionnaires were subjected to statistical analyses.
Results:
There was a statistically significant difference in the performance of surgical residents who have been trained on the new pelvitrainer in the study group compared to controls, which was reflected by the time spent to perform the procedure and the number of mistakes. This was more apparent with residents who successfully completed the three levels of pelvitrainer exercises than those who didn't. Residents in the study group showed increased interest in pelvitrainer exercises.
Conclusion: The new pelvitrainer might be a useful and cheap adjunct to surgical resident training in our hospitals as well as others in developing countries.

Many new software development methods such as agile and iterative development require closer communication among developers compared to traditional ones. However today, many IT engineers are not good at communicating with others. Therefore, we are developing software engineer education curriculum with enhancement of communication skills (more specifically, consensus-building skills) in mind. We are adopting case-centered methods, in which both software development process and importance of consensus can be understood through actual experiences. For evaluation, we have applied our educational case method to six computer science undergraduates, composed in two groups of three persons each. As the result, consensus-building workshop in our curriculum was effective in achieving closer communication.
近年、アジャイルや反復開発など緊密なコミュニケーションを前提とする開発手法が普及してきている。しかし、他者とのコミュニケーションを拒むソフトウェア技術者の存在をはじめ、現在 のソフトウェア業界ではコミュニケーションスキルの向上は必ずしも実現されていない。そこで筆者らは、新人に対しコミュニケーションスキル、特に合意形成スキルを重視した技術者教育を行うことが重要だと考え、教育手法を設計・試行している。具体的には、開発プロセスをこなす中で合意形成の重要性を体験できるような、ケース中心の教育手法を採用している。その検証のため、大学4年生6名に集まってもらい、それぞれ3名のグループに分かれ、ケースを基に開発を進める実験を行った。その結果、コンセンサスを体感するワークショップを行う事で、コミュニケーションをより密にする開発を行う事が出来ることを確認した。
