Backgrounds: Computers and gadgets are modern tools for assisting Senior High School students' work. However, using gadgets more than 2 hours a day may cause computer vision syndrome (CVS), which can interfere with academic activities. CVS main symptom is dry eyes. Objectives: CVS could be prevented by applying the 20-20-20 rule and artificial tears. Results: A total of 100 students from two public high schools in Kediri with 50 students from each school were selected for this community service. All students diagnosed with CVS participated in the dissemination of 20-20-20 rule and artificial tear administration. The pre-test and post-test scores, the Tear Break Up Time Test (TBUT) and the Ocular Disease Surface Index (OSDI) were measured within two weeks. TBUT and OSDI are parameters for measuring dry eye. Likewise, interviews were conducted to assess the adherence to the 20-20-20 rule and artificial tea administration. The results showed the knowledge level increased (p <0.0001). Most students understood 20-20-20 rule and how to administer artificial tears correctly. However, the adherence to both methods was approximately 50%. There was an improvement in the TBUT (p <0.0001) for dry eyes but not for OSDI (p> 0.05). Conclusions: Applying the 20-20-20 rule and artificial tears could be used for CVS treatment.

We proposed a mediation model to examine the effects of age, education, computer knowledge, and computer anxiety on computer interest in older adults. We hypothesized that computer knowledge and computer anxiety would fully mediate the effects of age and education on computer interest. A sample of 330 older adults from local senior-citizen apartment buildings completed a survey that included an assessment of the constructs included in the model. Using structural equation modeling, we found that the results supported the hypothesized mediation model. In particular, the effect of computer knowledge operated on computer interest through computer anxiety. The effect of age was not fully mitigated by the other model variables, indicating the need for future research that identifies and models other correlates of age and computer interest. The most immediate application of this research is the finding that a simple 3-item instrument can be used to assess computer interest in older populations. This will help professionals plan and implement computer services in public-access settings for older adults. An additional application of this research is the information it provides for training program designers.

This dissertation addresses user responses to the introduction of Brain-Computer Interface technologies (BCI) for gaming and consumer applications in the early part of the 21st century. BCI technology has emerged from the contexts of interrelated medical, academic, and military research networks including an established computer and gaming industry. First, I show that the emergence and development of BCI technology are based on specific economic, socio-cultural, and material factors, and secondly, by utilizing user surveys and interviews, I argue that the success of BCI are not determined by these contextual factors but are dependent on user acceptance and interpretation. Therefore, this project contributes to user-technology studies by developing a model which illustrates the interrelations between producers, users, values, and technology and how they contribute to the acceptance, resistance, and modification in the technological development of emerging BCI technologies. This project focuses on human computer interaction researchers, independent developers, the companies producing BCI headsets, and neuro-gadget companies who are developing BCI's for users as an alternative interface for the enhancement of human performance and gaming and computer simulated experience. Moreover, BCI production and use as modes of enhancement align significantly with social practices of play which allows an expanded definition of technology to include cultural dimensions of play. ; Ph.
