BACKGROUND Persistent cognitive impairment is prevalent in unipolar and bipolar disorders and is associated with decreased quality of life and psychosocial dysfunction. The screen for cognitive impairment in psychiatry (SCIP) test is a validated paper-and-pencil instrument for the assessment of cognition in affective disorders. However, there is no digital cognitive screening tool for the brief and accurate assessment of cognitive impairments in this patient group. OBJECTIVE In this paper, we present the design process and feasibility study of the internet-based cognitive assessment tool (ICAT) that is designed based on the cognitive tasks of the SCIP. The aims of this feasibility study were to perform the following tasks among healthy individuals: (1) evaluate the usability of the ICAT, (2) investigate the feasibility of the ICAT as a patient-administered cognitive assessment tool, and (3) examine the performance of automatic speech recognition (ASR) for the assessment of verbal recall. METHODS The ICAT was developed in a user-centered design process. The cognitive measures of the ICAT were immediate and delayed recall, working memory, and psychomotor speed. Usability and feasibility studies were conducted separately with 2 groups of healthy individuals (N=21 and N=19, respectively). ICAT tests were available in the English and Danish languages. The participants were asked to fill in the post study system usability questionnaire (PSSUQ) upon completing the ICAT test. Verbal recall in the ICAT was assessed using ASR, and the performance evaluation criterion was word error rate (WER). A Pearson 2-tailed correlation analysis significant at the .05 level was applied to investigate the association between the SCIP and ICAT scores. RESULTS The overall psychometric factors of PSSUQ for both studies gave scores above 4 (out of 5). The analysis of the feasibility study revealed a moderate to strong correlation between the total scores of the SCIP and ICAT (r=0.63; P=.009). There were also moderate to strong correlations between the SCIP and ICAT subtests for immediate verbal recall (r=0.67; P=.002) and psychomotor speed (r=0.71; P=.001). The associations between the respective subtests for working memory, executive function, and delayed recall, however, were not statistically significant. The corresponding WER for English and Danish responses were 17.8% and 6.3%, respectively. CONCLUSIONS The ICAT is the first digital screening instrument modified from the SCIP using Web-based technology and ASR. There was good accuracy of the ASR for verbal memory assessment. The moderate correlation between the ICAT and SCIP scores suggests that the ICAT is a valid tool for assessing cognition, although this should be confirmed in a larger study with greater statistical power. Taken together, the ICAT seems to be a valid Web-based cognitive assessment tool that, after some minor modifications and further validation, may be used to screen for cognitive impairment in clinical settings.

Management of academic activities at Mahendradata University is still using manually ways, which means that it has not used an integrated information system yet, for the example the process of registering new students, arranging lecture schedules, filling in student KRS, managing lecture attendance, and managing student grades. Nowadays cultural changes have been marked by the increasingly rapid use of the internet. The internet as an information resources for its existence has now become a necessity. The benefits of the internet are quite large, especially in the world of business, entertainment and education. This system is designed to assist academic processes at the University of Mahendradata. The academic processes that have been analyzed and applied in this developed system are the process of preparing schedules, plotting teaching lecturers, printing KRS, printing lecture attendance, presenting inputs, filling in grades, and printing KHS. And the University can immediately develop a new system in order to work optimally. System design that has been used in developing this system uses the SDLC method, the waterfall method. The implementation of the system uses the PHP programming language Codegniter and MySQL database. The results of this study are in the form of an academic system design at the University of Mahendradata. This developed system is aim to assist the academic processes at the University of Mahendradata

Bus is one of public transportation and as the most preferable by Indonesian to support their mobility. The high number of bus traffics then demands the bus management to provide the maximum service for their passenger, in order to gain public trust. Unfortunately, in the reality passenger list’s fraud is often faced by the bus management, there is a mismatch list between the amount of deposits made by bus driver and the number of passengers carried by the bus, and as the result it caused big loss for the Bus management. Automatic Passenger Counting (APC) then as an artificial intelligence program that is considered to cope with the bus management problems. This research carried out an APC technology based on passenger face detection using the Viola-Jones method, which is integrated with an embedded system based on the Internet of Things in the processing and data transmission. To detect passenger images, a webcam is provided that is connected to the Raspberry pi which is then sent to the server via the Internet to be displayed on the website provided. The system database will be updated within a certain period of time, or according to the stop of the bus (the system can be adjusted according to management needs). The system will calculate the number of passengers automatically; the bus management can export passenger data whenever as they want. There are 3 main points in the architecture of modeling system, they are information system design, device architecture design, and face detection mechanism design to calculate the number of passengers. A system design test is carried out to assess the suitability of the system being built with company needs. Then, based on the questionnaire distributed to the respondent, averagely 85.12 % claim that the Face detection system is suitability. The score attained from 4 main aspects including interactivity, aesthetics, layout and personalization

The development of the times and the development of the Internet have changed people’s consumption concepts. The author has conducted user research on user groups such as college students. After data analysis, the demand for resource sharing and trading of second-hand goods of college students was transformed into the function point of the trading platform. The APP was designed and developed to solve the needs of college students to share and exchange resources on campus. The APP’s main functions are second-hand commodity trading and virtual resource trading.

Senior citizens are comparatively vulnerable in accessing learning opportunities offered on the Internet due to usability problems in current web design. In an effort to build a senior-friendly learning web as a part of the Life-long Learning Network in Shanghai, usability studies of two websites currently available to Shanghai senior citizens were conducted, with the intention of integrating these websites into a senior learning web as well as promoting accessibility for senior users. Through this study usability problems were identified generating suggested changes for designing websites focused on learning by seniors. This study contributes empirical findings to the field of information system design and its accessibility for seniors.
