This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. Mandible at different ages
The Mandible at birth:
I. The Mandible at birth is made up of two separate halves, they are united later on
by fibrous tissue at the midline. The two halves of the Mandible joint at an area
called symphysis menti.
II. At birth there are no teeth, the size of the Mandible bone is too small to carry any
teeth but it carries the tooth germ of both the decidious and permanent teeth in
its bony crypts.
III. The mandibular canal runs near the lower border of the mandible while the
mental foramen opens below the crypt of the lower D.
IV. There is no mental protuberance present at that age.
V. The sigmoid notch is very shallow, the ramus bone is small and makes an angle of
170 degrees with the body of the mandible this angle is called the mandibular
angle
VI. The coronoid process is higher than the condyle. The condyle is present at the
same line with the upper border of the mandible.
3.
4. The Mandible at age of 3 years:
I. The two halves of the mandible joint together at the end of the first year
or beginning of the second year of children.
II. The body of the mandible bone starts growing to be able to occupy the
decidious and after that the permanent teeth, also the body increases in
height by the growth of the alveolar bony socket and the growth of the
first decidious teeth
III. The mandibular angle becomes smaller than at birth and closer to the
adult mandibular angle as it changes from 170 degrees to 140 degrees
5.
6. The Mandible at the age of six years:
I. The mixed dentition starts by the eruption of the first permanent molar.
II. The mandibular canal is placed above the mylohyoid line.
III. The opening of the mental foramen lies midway between the upper and
lower border of the body of the mandible.
IV. The mandibular angle more closer to the adult mandibular angle.
V. The growth of the mandibular bone causes bone remodeling, the
remodeling of the bone means resorption in certain regions
accompanied with apossition in other regions.
8. • The Mandible at Adult age:
I. The height and length of the mandible increase by the increase of size of
the alveolar bone and the eruption of the permanent teeth.
II. The mandibular canal is in a parallel position to the mylohyoid line.
III. The mandibular canal and mental foramen are both positioned midway
to the upper and lower borders of the mandible, usually the mental
foramen lies below the sockets lower 5 or lower 4 but in some rare
cases it lies between both sockets.
IV. The appearance of mental protuberance gives the chin appearance in
adults.
V. The coronoid is at a lower level than the condyle.
VI. The sigmoid notch becomes deeper
VII. The mandibular angle becomes from 110-120 degrees.
9.
10. Mandible at old age:
I. There is a decrease in the size of the mandible due to lose of permanent
teeth and the resorption of the alveolar process.
II. The loss of the permanent teeth and decrease in size of the mandible
cause the mental foramen and mandibular canal to become positioned
near the upper border of the mandible.
III. The mandibular angle becomes bigger than at adult age because due to
the loss of teeth the person tries to bring the lower and upper jaws near
each other for mastication, also the ramus becomes oblique for the
same reason.
IV. The mandibular angle becomes 140 degrees.
V. the condyle bends backward and become in lower level than the
coronoid process.
VI. The sigmoid notch is shallower than adult.

14. The Physiologic Tooth Form Protecting
The Peridontium
What is the Peridontium?
The peridontium is the supporting system of the tooth the peridontium is
formed of:
Gigiva
Periodontal ligament
Alveolar bone proper
Cementum
15.
16. The teeth have certain outline and curvatures
that serve in supporting the teeth and that
curvature is so finely drawn that any changes in
these dimensions may seriously injure the tooth
in the future. There are certain factors that may
affect the periodontum:
I. Direct factors
II. Indirect factors
17. 1. The direct factors consist of:
• The proximal contact area
• The interproximal spaces
• Embrasures or spillway
• Facial and lingual contours of the crown
• Curvature of the cervical line mesially and distally
2. The indirect factors consist of:
• Cusp forms
• Root forms
• Root/Crown ratio
• Angle of the tooth axis in the jaw bone
• Self cleansing ability of the tooth which consists of:
1. The smooth rounded surface of tooth and brushing activity of tongue and
cheeks.
2. The flushing activity of saliva.
3. The friction of food material during mastication.
4. The efficient use of tooth brush during home care of teeth.
18. 1.The proximal contact area:
A. What is the proximal contact area?
The proximal contact area is the spot on the proximal tooth surface where the
tooth touches the tooth adjacent to it in the same dental arch
The proper location of the contact areas can be observed from:
• The labial or buccal aspect
• The incisal or occlusal aspect
B. The normal location of the contact areas are:
• Every tooth has distal contact area in a more cervical area the the mesial
contact area
• The contact area is wider in posterior teeth than in anterior teeth and
more cevically in postion
• The contact area is centered labioligually in anterior teeth while in
posterior teeth it is deviated more bucally
19. C. What are the importance's of the proximal
contact area?
• It stabilizes the tooth within the alveolus which thereby stabilizes the
dental arches
• It helps prevent food impaction which can lead to decay and periodontal
problems
• It protects the interdental papillae of the gingival
20.
21. 2. The interproximal spaces:
A. What is the definition of interproximal spaces?
The interproximal space is a triangular space between adjacent teeth cervical
to their contact, the sides of the triangle are the proximal surfaces of the
adjacent teeth and the apex of the triangle is the area of contact of two teeth.
This space is occupied by the interdental papilla
B. What are the importance’s of the interproximal spaces:
• The healthy interdental papilla is smooth and elastic tissue that prevent
food stagnation
• Interproximal space gives sufficient space for the alveolar bone between
the neighboring teeth to support them in their sockets
22.
23. 3. The embrasure or spillway:
A. What are embrasures?
Embrasures are triangle shaped space or area between two adjacent teeth in
the same dental arch, where their proximating surface diverge from the area
of contact facially, lingually, and oclussaly.
Also there is a good relation between the location of contact areas and the
embrasures:
• The lingual embrasures are larger than the facial ones since most teeth are
narrower on the lingual side than the facial side, the lingual embrasures
also are larger than the buccal embrasures in posterior teeth more than in
anterior teeth.
• The incisal embrasure is shallow and narrow faciolingually on the anterior
teeth but broad in posterior teeth this is because the contact area is more
cervical in the posterior teeth than in the anterior teeth.
24. B. The importance of the embrasure’s are as follows:
• They make a spillway for the escape of food during mastication thus
reducing the forces upon the teeth.
• They make the teeth self cleansing because the rounded smooth surface
of the crowns are more exposed to the cleansing action of foods, fluids
and the friction of the tongue, lips, and cheeks. If there was no escape way
for the food the lodgement of food would cause to very poor oral hygiene.
• They allow proper stimulation for the gingival by permitting the proper
degree of frictional massage during mastication.
25.
26. 4. Facial and lingual contours of the crown.
A. The location of the facial and lingual contours:
• The height of contour on both labial and lingual surfaces of all the anterior
teeth is located in the cervical third.
• The height of contour of the buccal surfaces of all posterior teeth is
located in the cervical third.
• The height of contour of the lingual surfaces of all posterior teeth is
located in the middle third except the lower second premolar where it is
located at the oclusal third.
27. B. The physiological importance of these uniform curvature:
• The curvature holds the gingival under definite tension.
• They protect the gingival margin by deflecting food away from it during
mastication.
• The proper curvature will deflect food over the gingival margin preventing
unnecessary frictional irritation, but will allow some massage to soft
tissue.
C. If the proper curvature of teeth was replaced by improper contour by
unsuccessful dental restoration the following will occur:
• If the proper contour are absent or too small the gingival tissue will be
pushed apically and gingival recession will occur.
• If the curvature is too great there will be too much protection of the
gingival from proper massage and also the gingival will lose it’s tone. The
food material will accumulate around the gingival area resulting in chronic
inflammation.
28.
29. 5. Curvature of the cervical line mesially and
distally.
A. The curvature of the cervical line from different aspects:
• The curvature of the cervical line mesially and distally differs in different
teeth generally speaking this curvature is greater in the anterior teeth
than in the posterior teeth .
• In individual tooth it’s greater mesially than distally.
• It tends to be straight buccolingually in the distal surface or even the
mesial surfaces of some molars.
30. B. The importance of the curvature of the cervical line mesially and distally:
• The importance of the curvature of the cervical line is due to the face that
it is the site of attachment of the gingival to the tooth by means of a
structure called the attachment epithelium .
• If the teeth are in normal alignment and contact, the attachment
epithelium follows the curvature of the cervical line but not necessarily at
the same level. Any break in this epithelium will result in major injury to
the periodontium due to the penetration of the bacteria and their toxins
causing damage to the investing tissue of the tooth.
