Nurse is a profession that has a quite high workload. It can be seen from how often they should encounter situations which compel them to undergo precisely right decision in saving patients’ lives. Various environmental conditions increase the frustration rate of the nurses, such as noise of the crowds and medical equipment, as well as smell of medicines and wounds at once. Moreover, demands from the patients’ family make it even tougher for them. Therefore, this study aims to measure the mental workload of the nurses at Intensive Care Unit (ICU) and emergency unit (IGD) in the Hospital ZA based on their years of service. The study was conducted using the method of NASA-TLX (National Aeronautics and Space Administration – Task Load Index). It measured the workload in six dimensions: Mental Demand (MD), Physical Demand (PD), Temporal Demand (TD), Own Performance (P), Effort (EF), and Frustration Rate (FR). The results of the study show that the average value of the nurses’ workload at ICU and IGD is in the category very high (respectively 80 and 83) for the nurses with 0-3 years of service, and the most contributing factor for both the primary groups is the effort (EF).
The cockle immerses in the substrate of the intertidal zone. Their conditions and growth factors are highly dependent on nutrients around the waters of Kendari Bay. Therefore, this study aims to determine the relationship between length, weight, and condition factors. The study was conducted in March 2016 to February 2017 at the intertidal zone of Kendari Bay. The samples were collected with a shovel in a 1x1 m square transect monthly. Furthermore, the length and weight of the shells were measured using a calliper and a digital scale with an accuracy of 0.5 cm and 0.001g, respectively. The cockle was oven-dried for 48 hours. Simple linear regression was used to analyze the relationship between length and weight, while the condition factors were examined using the Mann-Whitney test. The results showed that male and female cockle shells had b values in the negative allometric and isometric categories, which spread from the respective ranges of 2.31-3.06 and 2.21-3.23. The b values for males and females increased in March-September and then decreased in October-February. Meanwhile, the condition factors of male and female mussels based on size and time of observation were not significantly different and ranged from 3.24±1.33-7.07±0.43 and 2.94±0.54-6.63±1.09. The highest condition index was discovered in October, March, and August, respectively, while the lowest occurred in June and September.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
