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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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.

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. Survey is a non-experimental type of
research that attempts to gather information
about the status quo for a large number of
people by describing present conditions
without directly analyzing their causes.
Definition
4. Monitoring trends in oral
health
and disease:
When national
surveys are repeated
periodically under general
similar conditions, broad oral
health trends over time can
be estimated, provided the
sampling design so
permits.The
WHO's pathfinder survey
protocol when repeated
periodically can assess
trends in health and disease
and it is assumed that the
results are valid enough to
support national policy
decisions.
Policy development:
Survey data can be used to
establish oral
health strategies. Scotland
has successfully
used survey data to develop
its oral health
policy. A number of
American States
switched their primary
preventive focus from
fluoride mouth-rinsing to
sealant application
after statewide surveys
showed most carious
lesions to be in pits and
fissur
Program evaluation:
Survey data are
often used to evaluate
programs though the
principle that
association does not
show cause-and-effect
needs to be
remembered.The success
of particular programs
can only be inferred from
survey data, though the
more localized the survey
and the program, then
the more plausible is the
inference.
5. Assessment of dental
needs:
Although surveys
can be used for assessment
of needs, there is a clear gap
between the criteria used in
surveys and those applied
for individual patient care.
e.g. criteria for caries in
surveys usually are based on
cavitation, but dentists
generally intervene at
an earlier stage in the
carious process.
Providing visibility to
dental issues:
The visibility that oral
health acquires through
the mere existence of
data from a national
survey may be the most
important of all uses of
survey data.
6. METHODS OF DATA COLLECTION
Health interview survey: (face-to-face survey)
It is an invaluable method of measuring
subjective phenomena, such as perceived morbidity, disability and impairment;
opinions, beliefs and attitudes and some behavioral characteristics.
Health examination survey: This survey is carried out by teams consisting of
doctors and auxiliaries.
Disadvantages:
1)It is expensive and cannot be carried out on an extensive scale.
2)The method also requires consideration of providing treatment to people found
suffering from certain disease.
7. METHODS OF DATA COLLECTION
Health records survey : It involves the collection of data from health service
records. This is obviously the most economical method of collecting data.
Disadvantages:
a. The data obtained is not population-based.
b. Reliability is open to question.
c. Lack of uniform procedures and standardization in the recording of data.
Questionnaire survey:
The use of questionnaires and interviews is
a standard method of data collection in
clinical,epidemiological, psychosocial
and demographic research. It is used for
measuring subjective phenomena.
8. METHODS OF DATA COLLECTION - QUESTIONARIE SURVEY
Types:
1) Mailed
questionaries
2) Telephone
questionaries
3)Face-to-face
questionaries
ADVANTAGES:
• Simple
• Economical
• Standardization -
Written instructions
reduce biases from
differences in
administration.
• Anonymity -Privacy
encourages candid
and honest
responses to
sensitive questions.
Disadvantages:
A certain level of
education and skill is
expected from the
respondents.
There is usually a high
rate of nonresponse.
9. Open ended
questions-
Free response
Closed ended
questions- fixed
alternative
The subject answers in his own words. This may produce difficulties when
interpreting the responses, e.g. How many cigarettes do you smoke per day?
They are answered by choosing from a number of fixed alternative
response.
Eg: How many cigarettes do you smoke per
day?
a. Upto -10 b. 10-20
c. 20 -30 d. More than 30
The 2 types of scales most commonly used are :
1)Likert Scale: (Summative)
2)Guttman scale: (Cumulative)(Scalogram)
????
10. Likert Scale: (Summative) Commonly used to quantify
attitudes and behavior. Respondents are asked to select a
response that best represents the rank or degree of their
answer.
E.g. The respondent may be asked to indicate whether he
strongly agrees, agrees, neither, disagrees or strongly
disagrees with the statement. Each response is assigned a
number. The points of each item is added.
Guttman scale: (Cumulative) (Scalogram)
These contain a series of statements that
express increasing intensity of a characteristic.
The respondent is asked to agree or disagree
with each statement. The respondents score is
the total number of items with which he agrees
or disagrees.
12. 1) Establishing the objectives:
The objectives can either be stated in the form of a hypothesis which is to be
tested, or, the objective may be stated by describing what is to be measured.
The starting point of a study is frequently an expression of a null hypothesis, which
states that there is no difference between the groups.
Eg: There is no difference in the periodontal
status of males and females aged 35-44 years in
Mangalore. The objective of the
study is then to test this hypothesis
Eg: To determine the prevalence of dental
caries among 12 year old school children
in Mangalore.
13. 2) Designing the investigation:
Survey protocol: It is important to prepare a written protocol
for the survey, which should contain,
Main objective and purpose of the survey,
A description of the type of information to be collected and
of the methods to be used.
A description of the sampling methods to be used.
Personnel and physical arrangements.
Statistical methods to be used in analyzing the data.
A provisional budget.
A provisional time-table of main activities and responsible
staff.
14. 1 ) Obtaining approval from authorities:
Permission to examine population groups must usually be obtained
from a local, regional or national authority.
E.g. If school populations are to be examined, schoolauthorities and
the parents should be approached for obtaining permission.
2) Emergency care and referral:
All survey teams should be equipped for and
ready to provide emergency care if required.
It is also the responsibility of the examiner to
ensure an appropriate care facility is made.
3 ) Budgeting: A budget for the survey should be prepared
which should include all the resources required to carry out the
survey.
15. 3) Selecting the sample:
Sample
Collect information from these
people to find answers to your
Research questions
Study population:
Sampling units
Make an estimate of their
prevalencein the study
population from sample
findings
Select a few
sampling units from
the study
population
Reference or
parent
population
16. METHODS OF SAMPLING :
1) Simple random sampling
It is a technique whereby each
sampling unit has the same probability
of being selected.
Every item in population has an equal
chance of being included.
Basic procedure:
• Prepare a sampling frame
• Decide on the size ofthe sample
• Select the required number of unit
17. 1) Simple random sampling
LOTTERY METHOD TABLE OF RANDOM
NUMBERS
Here the population units are
numbered on separate slips of paper of
identical size and shape
These slips are then shuffled and blind
fold selection of the number of slips is
made to constitute the desired sample
size
Random numbers are haphazard
collection of certain numbers,
arranged in a cunning manner to
eliminate personal selection or the
unconscious bias in taking out the
sample
18. The first unit is chosen at random and
then, other units are chosen in a
systematic way.
E'.g. Every third patient visiting the
dentist.
(2) Systematic sampling
19. (3) Stratified sampling
The population is first divided into
subgroups or strata according to
certain common characteristics. Then
random or systematic sampling is
performed independently in each
stratum:
Stratified random sampling
Stratified systematic sampling
20. (4) Cluster sampling
A simple random sampling is
selected, not of individual subjects,
but of groups or clusters of
individuals.
The sampling units are clusters and
the sampling frame is a list of these
clusters
21. (5) Multiphase sampling
This is used to take basic data from a large sample
and details from a subsample.
It is a sub-sampling within groups chosen as
cluster samples. The first stage is to select the
groups or clusters.
Then sub-samples are taken in as many
subsequent stages as necessary to obtain the
desired sample size
Eg : Nutritional status of the country
(6)Multistage sampling
22. (7) Panels
They are useful for studying trends. A sample is randomly
selected and then data are collected from the sample on
several occasions.
E.g. Every person is interviewed every 6 months.
A small sample is tested in order to answer certain
questions about the population.
If the questions are not answered, the number of
subjects or units in the sample is increased
gradually until the conclusions may be drawn.
(8) Sequential sampling
23. The examination should be as automatic as
possible to obviate excessive intrusion of
subjective thought. Therefore it should be
performed quickly.
The object of epidemiological surveys is to
examine subjects in fairly large numbers.
Excessive time spent on each individual
necessitates a reduction in the number of
individuals seen.
4.Conducting the Examination : BASIC ORAL HEALTH
EXAMINATION
5 - 10 minutes
15 - 20 minutes
24. • Plane mouth mirrors - 30 per examiner
• Periodontal probes - 30 per examiner
• Several pair of tweezers
• Containers and concentrated sterilizing solution.
• A wash basin
• Cloth or paper hand towels
• Gauze.
Instruments & supplies
Infection control :
Current national recommendations and
standards should be followed for
• Infection control
• Waste disposal
• Disposable masks, gloves, protective eyewear
recommended.
25. CHAIR: Preferable with a head rest. Most comfortable
situation is for the subject to be on a table/bench,
and examiner to sit behind the subject’s head.
ILLUMINATION: A separate unit lamp attached to
head of the examiner fibre optic light source.
CLEANING: Method to remove loose debris where
necessary.
ASSESSMENT FORMS: Adequate supply. Avoidance of
crowding and noise around the examiner.
RECORDER: Live or tape for receiving information
called by the examiner.
ORGANIZING CLERK: To maintain constant flow of
subjects and to enter general descriptive info on
forms.
EXAMINATION AREA :
26. It is used to calculate intra and inter examiner
reproducibility.
It is an index which compares the agreement
against that which might be expected by chance.
Kappa can be thought of as the chance-corrected
proportional agreement, and possible values range
from + 1 (perfect agreement) via 0 (no agreement
above that expected by chance) to -1 (complete
disagreement).
KAPPA STATISTIC:
KAPPA VALUE INTERPRETATION
1 Total agreement
> 0.8 Good
agreement
0.6 - 0.8 Substantial
agreement
0.4 - 0.6 Moderate
agreement
27. CLASSIFICATION OF TYPES OF INSPECTION AND
EXAMINATION :
TYPE 1: Complete examination using mouth mirror
,explorer, good illumination, full mouth radiographs, &
additional diagnostic methods (pulp testing, study models,
transillumination etc.)
TYPE 2: Limited examination, using mouth mirror and
explorer, bitewing radiographs. Periapical radiographs if
indicated.
TYPE 3: Inspection using mouth mirror ,explorer & good
illumination.
TYPE 4: Screening procedure - tongue depressor,
available illumination.
28. (5)ANALYZING DATA :
Once the examination procedures of a survey have been completed,
the work of assembling the material and interpreting it begins.
01
02
The analysis of findings has two
components:
Data processing (statistical analysis)
Interpretation of result
29. (6) Drawing the conclusions and publishing the report:
The conclusions are specifically related to
the investigation that has been carried out
and The final step in a survey procedure should be
the construction of a report with or without a set of
recommendations. Clearness and simplicity should
be sought.
30. 1. Statement of the purposes of the survey.
2. Material and methods.
A) Description of area and population served.
B) Types of information collected
C) Methods of collecting data
D) Sampling method
E) Examiner personnel and equipment
F) Statistical analysis and computational procedure
G) Cost analysis
H) Reliability and reproducibility of results.
3. Results: They should be tabulated and illustrated
appropriately.
4. Discussion and conclusions: The investigations, its
findings and its conclusions are discussed.
5. Summary.
31. ORAL HEALTH SURVEYS
PATH FINDER SURVEYS
The special factors associated with the most
common oral diseases which have enabled a
practical economic survey sampling methodology to
be defined, called the
"pathfinder method".
The "pathfinder method" is a stratified cluster
sampling technique, which aims to include the most
important population subgroups likely to have
differing disease levels.
33. PILOT SURVEY NATIONAL PATH FINDER SURVEY
Only the most important
subgroups in the
population.
One or two index ages
12 years and one other
age group.
Provides the maximum
amount of data needed
to commence planning
Incorporates sufficient
examination sites to cover all
important subgroups of the
population
Atleast three of the index age
groups.
Suitable for collection of data for
planning purposes & monitoring
of oral health programmes in all
countries regardless of the level
of disease, availability of
resources/complexity of care.
35. 5 YEARS INDEX AGE GROUP
Children should be examined between 5th - 6th
birthdays.
• Caries levels in Primary dentition
• Exhibit changes over a short span of time than
in permanent dentition at other index ages
• In some countries, 5 years is also the age at
which children begin primary school.
36. 12 YEARS INDEX AGE GROUP
• Children leave primary school.
• Last age at which a reliable sample may be
obtained easily through school system.
• All permanent teeth (except 3rd molars)
are likely to have erupted.
• Chosen as “global indicator age group
for international comparisons and
surveillance of disease trends”
37. 15 YEARS INDEX AGE GROUP
• Permanent teeth - exposed to oral
environment for 3-9 years.
• Assessment of caries prevalence and
periodontal disease in adolescents. (15-19yrs)
• In countries where it is difficult to obtain a
reliable sample of this
age group, it is customary to examine
individuals in two-three areas
38. 35 - 44 YEARS INDEX AGE GROUP
Standard age group for surveillance of oral
health conditions in adults.
• Planners & decision-makers can assess the full
effect of dental caries, level of severe
periodontal involvement, & general effects of
oral health care provided.
• Samples can be derived from organized
groups - office, factory workers etc.
• Care must be taken to avoid obvious selection
bias.
39. 65 - 74 YEARS INDEX AGE GROUP
• Has become important with the changes in
age distribution of populations and the
worldwide increase in lifespan.
• Estimate the manifestation of oral disease
from a life course perspective.
• Data needed : planning appropriate
interventions for older people and
for assessment of the ultimate effect of oral
health programmes
• Sampling - care should be taken to sample
adequately both house bound & active
members of this age group.
40. NUMBER OF SUBJECTS
The number of subjects in each index age group to
be examined ranges from a minimum of 25 to 50
for each cluster or sampling site, depending on the
expected prevalence and severity of oral diseases.
If this cluster distribution is applied to four index ages in the population
under study, the total sample is 4 x 300 = 1200.
Permits the identification of differences
- between urban and rural group.
- between socioeconomic groups.
- areas where prevalence is much higher or lower.
41. THE WHO ORAL HEALTH ASSESSMENT FORM
(1997)
The WH O Oral Health Assessment Form 1997 is a universally accepted and
used recording methodology for oral health surveys.
STANDARD CODES
If some of the oral health assessments are not carried out, or are not
applicable to the age group being examined, the unused sections of the
form should be canceled with a diagonal line, or by using code 9.
The forms are designed to facilitate computer processing of the result.
The two-digit numbers above or below some of the boxes indicate specific
teeth, according to the system used by the International Dental Federation
(FDI).
42. 1. Survey identification information
2. General information
3. Extra-oral examination
4. Temporomandibular joint assessment
5. Oral mucosa
6. Enamel opacities/hypoplasia
7. Dental fluorosis

71. Dentition status and treatment need: (boxes 66-161)
• Examination for dental caries - plane mouth mirror.
• Use of radiography for detection of proximal caries is not
recommended impractical in most filed situations.
• Examiners should adopt a systematic approach.
• Proceed in orderly manner from one tooth to adjacent
tooth or tooth space.
• A tooth should be considered present in the mouth
when any part of it is visible.
• If a permanent & primary tooth occupy the same space,
the status of permanent tooth should be recorded.
72. Dentition status and treatment need: (boxes 66-161)
• An entry must be made in every box pertaining to the coronal & root
status of a tooth.
• In children, root status is not assessed, so the corresponding boxes have
been omitted.
73. Dentition status and treatment need: (boxes 66-161)

exposed and showed no
evidence of treated
clinical caries.
1(B)Decayed crown
Undermind enamel
Detectable softened
floor
If carious lesion on root,
doesn't involve crown,it
should be recorded as
root caries,temporary
filling.
Decayed root: If the root
caries is discrete from the
crown and will require a
separate treatment, it
should be recorded as root'
caries.
2 (C) Filled crown, with
decay:
A crown that has
one/more permanent
restorations & one/more
ares are decayed
Filled root, with decay:
A root is considered
filled, with decay, when it
has one or more
permanent restorations
and
one or more areas that
are decayed.
74. Dentition status and treatment need: (boxes 66-161)
3(D)Filled crown with no
caries:
A crown that has one/more
permanent restorations are
present & there is no caries
anywhere.
Filled root, with no
decay:
A root is considered filled,
without decay,
when one or more
permanent restorations
are present and there is no
caries anywhere
on the root.
4(E)Missing tooth,due to
caries:
Permanent/primary teeth
extracted because of
caries.Recorded under
coronal status
5(-) Permanent tooth
missing due to any other
reason:

largest deviation from the normal relation is recorded. The following codes
are used:
0-Normal.
1 -Half cusp. The lower first molar is half a cusp mesial or distal to its normal
relation.
2 -Full cusp. The lower first molar is one cusp or more mesial or distal to its
normal relation.
78. Need for immediate care and referral: (boxes 177-180)
It is the responsibility of the examiner or team leader to ensure that referral to an
appropriate care facility is made, if needed.
Examples of conditions that require immediate attention include
periapical abscess and acute necrotizing ulcerative gingivitis.
Gross caries and chronic alveolar abscesses may also be recorded in box 178.
Three boxes are provided for the recording of the presence (code 1) of the
following condition:
