摘要

Insufficient effort has been made to investigate details of the diagnostic process, specifically information seeking and information integration. In this study, participants were asked to accomplish eight diagnostic tasks of locating the leaking position of some working material in a simulated nuclear power plant. The participants' information seeking actions and possibility judgments about all potential leaking positions were recorded and then described using eight dependent variables concerning their gains and expenses. Generalized linear mixed-models were used to evaluate the effects of time pressure and the correlations. The results showed that (1) information seeking and information integration were closely correlated in multifaceted ways; (2) higher diagnostic accuracy was associated with fewer information acquiring actions but with longer average intervals between these actions; and (3) high time-pressure induced speed-and-accuracy trade-offs in the sub-processes, and the overall diagnostic speed and accuracy were negatively related between individuals, but positively related between trials

Nails are the body part which are farthest from the heart and therefore receive oxygen at last. As a result the nails are the first who show the symptoms of a disease in the human body. Fingernails can be easily captured for diagnosis and there are no heavy equipment or no specific conditions required to use nail image for disease diagnosis, like in other tests and scanning processes. Human nails deliver beneficial information about complaints or any nutritive imbalances in the human body depending upon their shape, texture and colour. In human beings, numerous systemic and skin diseases can be easily analyzed through careful examination of nails of both the limbs. A lot of nail illnesses have been found to be primary signs of numerous underlying systemic illnesses. The colour, texture or shape changes in nails are signs of many diseases mainly affecting nails. Considering all these properties of nails a system is proposed that uses digital image processing (DIP) methods for identifying such changes in the human nail to get more precise results and predict numerous diseases effortlessly. With the emerging Internet of Things (IOT) concept the generated report is made available remotely, this will help users to reduce transportation efforts. As the system has to deal with large and private data, the security of data must be ensured. To keep the data confidential, the Blockchain concept which is one of the most emerging concepts in the field of data management is used. The paper contains the implementation of the digital image processing for feature extraction of nail images, usage of IOT (ThingSpeak cloud) for data storage and implementation of Blockchain to keep the system secured and theft free.
