A concept of a modular networked robot is introduced. A simple prototype of this kind of robot is developed to be accessible over web through wireless internet. The modularity is realized by dividing the robot into three modules: main, data acquisition and data processing modules. The main module consists of robot?s body and main processor not only to handle the data processing, but also to store the whole software-based solutions. The data acquisition module is attached with the remaining hardwares like sensors, microcontrollers and signal conditioner circuits. The data processing module represents the software-based system to filter, store, analyze and display the data or its final results. Finally, all modules are integrated through a web-based interface to realize a mobile control and monitoring system. In this thesis, the detail discussion is given only for the microcontroller-based solutions required in the system.

Background: The aim of I he study was to determine the prevalence of prolonged QTc-interval and it's relationship with the severity of liver dysfunction in liver cirrhotic patient in the outpatient clinic of Hepatology, Dr. Cipto Mangunkusumo General National Hospital Materials and Methods: cross sectional study. Eighty one subjects was recruited and being followed as a consecutive non random sampling. The patient was divided according to the modified Child-Pugh classification and undergo to the ECG examination (with minimal 2 leads have measured QT-interval; one of these is II, aVL, V, or V"; lead). Result: The prolonged QTc-interval prevalence in liver cirrhotic patient was found in 55 subjects (67,9%) with the mean 448.6 msec (SD = 28,9; 95% CI = 442.2 - 454.8). Using the Forward Stepwise method in multivariate analysis to the independent variables (p < 0.05) was found only the modified Child-Pugh classification had strongly correlation with the prolonged QTc-interval (OR = 11.2; 95% CI = 3.57-35.47; p = 0.000) Conclusion: The prolonged QTc-interval prevalence in liver cirrhotic patient is 67.9%. The prolonged QTc-interval were strongly associated with the seventy of liver dysfunction.
