The education based on the web (WBI) has need of the formation of a new educational paradigm which is different from the method of an existent traditional class as a model of a new teaching-learning. Also, a credit is recognized in case that the person concerned obtains a national certificate of qualification through establishment and promulgation by 【the law of the recognized credit etc.】 in the national educational reform. In such realities on-line learning-site of theory on the qualification of an information processing to use the web. However it is nearly difficult to find out the learning sites related to a subject for the information processing exercise revised in Aug, the year 2001. Thus, this thesis designed and embodied the educational system of the information processing exercise to reconstruct a Supervision Program for a scholastic examination test, a learning content of Visual Basic, a mock entrance examination, and a previous questions of practical in order to obtain the certificate of information processing qualification through a self-directed learning to use the web without limitation of time and space by the students-selves to apply 10 steps of a general design process with WBI to the method of development.

Background: This study was designed to assess the effects of pneumoperitoneum and positional changes on the autonomic nervous system (ANS) in laparoscopy-assisted vaginal hysterectomy (LAVH) patients. Methods: Systolic blood pressures and R-R interval were recorded for 5 minutes in 22 patients, and then power spectral analyses were conducted to evaluate the ANS. The following variables were measured at various positions: preinduction (BASE), prepneumoperitoneum (PREPP), pneumoperitoneum at head-down (PP), normoperitoneum at supine (POSTPP). Results: High frequency of heart rate variability (HRVHF), Low frequency of heart rate variability (HRVLF), Low frequency of blood pressure variability (BPVLF), LF/HF ratios of HRV (LFHFr) were significantly lower than that of BASE at PREPP. HRVHF, HRVLF, BPVLF were significantly lower than that of BASE at PP. At PP, normalized HF of HRV (nuHF) is significantly lower than that of BASE and normalized LF of HRV (nuLF) is significantly higher than that of BASE and PREPP (P<0.05). LFHFr was significantly lower than that of BASE and significantly higher than that of PREPP at PP. At POSTPP, HRVHF, HRVLF, BPVLF were significantly lower than that of BASE. But, BPVLF at POSTPP was higher than that of PP. Conclusions: We conclude that the pneumoperitoneum and trendelenburg positions caused sympathetic activation in LAVH patients.
