In mobile communication networks, forced call termination is due to two fundamental features: resource insufficiency and link unreliability [9].
On the other hand, teletraffic analysis of wireless communication systems taking into account both resource insufficiency and link unreliability is addressed in [9, 17 19].
Nevertheless, in [10, 25, 26], particular features of CRNs are not considered and forced call termination is considered to occur due only to resource insufficiency.
Contrary to [17 19], in our early work [9], a teletraffic analysis is performed taking into account both resource insufficiency and channel unreliability through a system-level model by introducing a simple call interruption process to model the effect of wireless channel unreliability.
Although failure to implement a 'learning on the job' model may be widespread its adverse impact is more marked in East Africa and its root causes related to resource insufficiency are more intractable.
Since the introduction of CHCs, these institutions have encountered difficulties due to limited resources, an insufficiency of staff members, and inadequate staff training [ 3].
Demands for health, social and nursing care arise when needs of people with dementia and their caregivers are not fulfilled, usually due to insufficiencies in resources especially related to manage everyday activities and a lack of social network [ 2].
This state of affairs reflects unrealistic expectations when defining the ceiling in the CPR and insufficiencies in the resource mobilisation process.
A demand for care is a result of one or more unmet needs, mainly due to insufficiencies in available resources.
The first dimension of the current problem is the insufficiency of resources while the second dimension stems from the lack of proper evaluation of the material to be used in conservation and restoration.
With all this, one would think that developed countries would have devoted greater resources to tackle water insufficiency and deficient sanitation at their source, rather than executing costly reactive rescue missions to deal with the epidemics, famines, refugee crises, and mass exoduses that are their consequences.
