Job Position

Employees are valuable asset in an organization. The organization can be defined as two types namely a profit or nonprofit company, and government institution. Employees as a capital human for these organization have big roles for performance measurement. Performance measurement of employee is used to determine whether the worker has been working efficient or not. Workload analysis is defined as analysis of a set or number of activities that must be completed by an organizational unit or position holder within a certain period of time. In this research, it will show employee workload analysis using two approaches in order to complete each other. Firstly, work sampling method was used to determine workload in physically. Secondly, NASA-TLX was utilized to analyze workload in mentally. Pareto method will also take a part for analysis the research result to be more comprehensive. This research has conducted in an East Java’s University-Indonesia. The respondents are employees who have each job description to do their work in each position. The employee’s workload will be calculated both physical and mental. From 25 position observed, show the job position who has strategic characteristic mostly have very high mental workload whereas the job position who has operational characteristic mostly have high physical workload

Tingginya produktivitas sebuah perusahaan ditentukan oleh kualitas output yangdihasilkan dari tenaga kerja yang berada di dalam perusahaan. Produktivitaskaryawan dipengaruhi oleh beberapa faktor, diantaranya beban mental dan bebanfisik. Dalam kegiatan operasional di bagian jetty, perusahaan masih belum bisamenentukan produktivitas operator karena tidak tetapnya jumlah kapal yang masukdalam sehari, sehingga produktivitas operator belum dapat diukur. Penelitian inibertujuan untuk mengukur produktivitas operator berdasarkan beban fisik danbeban mental. Metode yang digunakan dalam penelitian ini adalah work sampling,NASA-TLX, dan denyut jantung. Nilai rata-rata beban mental operator jetty sebesar75,50, sehingga beban mental operator jetty dikategorikan dalam keadaan sedang.Beban kerja fisik yang dikeluarkan oleh operator jetty sebesar 30,09 kj/menit,sehingga beban fisik operator jetty dikategorikan berat. Hal ini disebabkan karena,dalam bekerja operator jetty lebih banyak mengeluarkan energi fisik dibandingkandengan beban mental. Sedangkan, nilai rata-rata produktivitas operator jetty adalah sebesar 77%, sehingga perlu diadakan peningkatan produktivitas untuk membuat kegiatan operasional lebih efektif. Berdasarkan penelitian, maka dapat disimpulkan bahwa beban kerja yang sangat dirasakan dan berpengaruh bagi operator jetty adalah beban kerja fisik dan operator jetty belum dikatakan produktif karena nilai produktifivitas masih kurang dari 80% dikarenakan tingginya beban fisik sehingga operator lebih banyak menggunakan waktu menganggur untuk beristirahat.

Computer Interactions

The role of affect has been long studied in human–computer interactions. Unlike previous studies that focused on seven basic emotions, an avatar named Diana was introduced who expresses a higher level of emotional intelligence. To adapt to the users various affects during interaction, Diana simulates emotions with dynamic facial expressions. When two people collaborated to build blocks, their affects were recognized and labeled using the Affdex SDK and a descriptive analysis was provided. When participants turned to collaborate with Diana, their subjective responses were collected and the length of completion was recorded. Three modes of Diana were involved: a flat-faced Diana, a Diana that used mimicry facial expressions, and a Diana that used emotionally responsive facial expressions. Twenty-one responses were collected through a five-point Likert scale questionnaire and the NASA TLX. Results from questionnaires were not statistically different. However, the emotionally responsive Diana obtained more positive responses, and people spent the longest time with the mimicry Diana. In post-study comments, most participants perceived facial expressions on Diana’s face as natural, four mentioned uncomfortable feelings caused by the Uncanny Valley effect.

Abstract Background Within surgery, assistive robotic devices (ARD) have reported improved patient outcomes. ARD can offer the surgical team a “third hand” to perform wider tasks and more degrees of motion in comparison with conventional laparoscopy. We test an eye-tracking based robotic scrub nurse (RSN) in a simulated operating room based on a novel real-time framework for theatre-wide 3D gaze localization in a mobile fashion. Methods Surgeons performed segmental resection of pig colon and handsewn end-to-end anastomosis while wearing eye-tracking glasses (ETG) assisted by distributed RGB-D motion sensors. To select instruments, surgeons (ST) fixed their gaze on a screen, initiating the RSN to pick up and transfer the item. Comparison was made between the task with the assistance of a human scrub nurse (HSNt) versus the task with the assistance of robotic and human scrub nurse (R&HSNt). Task load (NASA-TLX), technology acceptance (Van der Laan’s), metric data on performance and team communication were measured. Results Overall, 10 ST participated. NASA-TLX feedback for ST on HSNt vs R&HSNt usage revealed no significant difference in mental, physical or temporal demands and no change in task performance. ST reported significantly higher frustration score with R&HSNt. Van der Laan’s scores showed positive usefulness and satisfaction scores in using the RSN. No significant difference in operating time was observed. Conclusions We report initial findings of our eye-tracking based RSN. This enables mobile, unrestricted hands-free human–robot interaction intra-operatively. Importantly, this platform is deemed non-inferior to HSNt and accepted by ST and HSN test users.

Background. Postpartum hemorrhage (PPH) is the leading cause of maternal death in the world. Non-technical skills (e.g. communication) are now recognized as a contributing factor to medical safety. In the field of simulation, screen-based simulations are currently very popular with computer/technological development. This study evaluates a screen-based simulation device, PerinatSims, developed to improve technical and non-technical skills in PPH situation. This experiment hypothesized that exposure and repetition of training with PerinatSims would improve the self-assessment of non-technical skills, and therefore increase the ability to manage PPH. Methods. The primary endpoint was a self-assessment of non-technical skills during simulation session of PPH on a digital simulator. Twenty French midwives performed three of nine 25 minutes sessions of PPH screen-based simulation. Four self-assessment questionnaires were administered at the end of each simulation session: a leadership/team working questionnaire (BAT), a negative feelings/emotional questionnaire (DASS-21), a Flow questionnaire and a mental load questionnaire (NASA-TLX). Results between sessions were compared using a repeated measures ANOVA followed by a Bonferroni post hoc test. Results. The study showed a positive evolution during the three screen-based simulation sessions: an increase of leadership and team working self-assessment, an increase of Flow sense, and a decrease of negative emotions (anxiety and depression in the DASS-21 score). Significant decrease of stress was found only between the second and the third sessions, and significant differences in the NASA-TLX were observed only in two dimensions, Performance and Frustration. Conclusion. A repeated exposure to PPH situations with a screen-based simulation tool improved the midwives’ self-assessment, especially for leadership, team working, emotion management and Flow sense. Furthermore, midwives had a very positive feedback on the device. They highlighted the desire to use PerinatSims more often to be trained to PPH management, for technical as well as non-technical skills.
