However, the latest study indicates the viability of utilizing virtual reality technology to build up social skills in autism sufferers. The result of the study manifests that there is a remarkable increase in various social cognitive measures. This discovery implies that virtual reality might be a promising social learning instrument to help improve social cognition and skills for autistic individuals. Forty ASD participants ranging from the age of 7 to 26 will be divided into two groups of age, which are children and young adults. In total there will be 10 sessions of virtual-based intervention in which the ASD participants will be guided by a coach and a researcher. Each of session has its own social objectives that need to be accomplished by the participants. There will be a pre-test and post-test to measure the progress of each of the participants' social skills and cognition. This research will be conducted for approximately three months in the hope that virtual reality can be deemed a useful therapy for ASD individuals.

A lot of hospitals have digital radio diagnostic modality that supports the DICOM protocol. However, the implementation of integrated radiology information system with medical imaging equipment is still very limited until now, especially in developing countries like Indonesia. One of the obstacles is high prices for radiology information system. Whereas the radiology information systems can be widely used by radiologists to provide many benefit for patient, hospitals, and the doctors themselves. This study aims to develop a system that integrates the radiology administration information system with radio diagnostic imaging modalities. Such a system would give some benefits that the information obtained is more accurate, timely, relevant, and accelerate the workflow of healthcare workers. This research used direct observation method to some hospital radiology unit. Data was collected through interviews, questionnaires, and surveys directly to some of the hospital's radiology department in Jakarta, and supported by the literature study. Based on the observations, the prototype of integrated patient registration systems in radiology unit is developed and interfaced to imaging equipment radio diagnostic using standard DICOM communications. The prototype of radiology patient registration system is tested with the modality MRI and CT scan.

Despite its importance, many healthcare challenges exist, as a result of increased costs that are not associated with the quality of healthcare. Consequently, the primary purpose of this investigation is to examine the role of information technology (IT) in mediating the effect of medical resources on clinical performance. Medical resources were measured using human resource and medical technology dimensions. The research capability is referred to as IT and knowledge management capabilities. An empirical survey was conducted at 34 accredited hospitals located in the Special Capital Region of Jakarta. A multivariate statistical analysis, applying structural equation modeling-partial least squares, revealed that the role of IT capabilities were statistically significant in mediating the effect of medical human resources on clinical performance. No significant direct effect of medical resources on clinical performance was observed. The results imply the significant role of IT capabilities in healthcare industries, particularly in hospitals in Jakarta, Indonesia.

Some of the reasons are because of these areas have special characteristics which are: 1) the data and information in the medical information systems consist of many data types, such as alphanumeric, graphics, images, and sounds; 2) health workers are always mobile in performing their duties; 3) the source data is not only coming from the physician or health worker but also could be obtained from high-tech medical equipment; 4) when an error occurs in any health care data processing could caused death to the patient. The main function of the medical information system is not only used for management purposes but it also used for managing clinical data that will be useful for the development of medical science. Radiology department is one of the hospital departments that use many computerized systems. Therefore, the implementation of information systems in ra...
