2
Informatics

• Information Science (library science)
• The sciences concerned with gathering and
  manipulating and storing and retrieving and
  classifying recorded information

3
Informatics

• The application of computers and statistics to
  the management of information. For example, in
  the Human Genome Project, informatics has
  permitted the development and use of methods to
  search databases quickly, analyze DNA sequence
  information, and predict protein sequence and
  structure from DNA sequence data.

Informatics, the Bottom Line

• Purpose (output) to predict protein sequence and
  structure
• Requirements analyze for patterns
• Knowledge needed statistics
• Tools needed computer software
• Input DNA sequence data
• What data to collect? Why these attributes?
  Domain Knowledge needed.

6
What is IS?

• Management allocation of resources
• Information data analysis
• Systems (1) Information Technology, (2)
  Organization Restructuring due to IT
  implementation
• IS may help create efficiency, but it is not
  efficient by itself without planning

7
Where can IS help?

• Value Chain
• Input Logistic
• Processing
• Output Logistic
• Marketing and Sales
• Services

8
Value in Informatics

• Important Accuracy and Validity
• Accuracy reduce the cost of measurement and
  verification (including not having to verify)
• Validity reduce the cost of testing so the
  sample size my increase, or the test may be
  refined

9
The Need of Operational Definition

• Without quantifiable attributes, IS can only, at
  best, serve as a storage service
• The determination of attributes and their values
  are assessed require domain knowledge
• Reengineering converting qualitative attributes
  to quantitative ones

10
Quality in Healthcare

• What is quality?
• What is the goal of healthcare?
• A list of measurement immunization ratio, life
  expectancy, days off work, etc.
• Really?

11
Quality in Healthcare Education

• Domain Knowledge what to do and how to do
• Communication sender -gt medium -gt receiver
  coding -gt transmit -gt decoding
• Waithow do you define quality here?

12
Quality in Health Education

• ????
• ?????
• Which part of what to do and how to do will
  generate the highest benefit and avoid disasters?
• After we figure this part out, then what devices
  can we use to implement the system?

13
Quality in Health Education

• Which part of such education should be memorized?
  Kept as Reference?
• Just-in-time Learning in Education
• JIT Learning in Health Education?
• The effect of mobile device (including 3G phones
  and wireless PDAs) to referencing

14
Quality in Informatics

• E(x) S xP(x)
• To be able to predict we need to know what
  attributes to observe and have a way of measuring
  their changes
• We need to know the probability (i.e., the
  distribution) of each potential values for the
  attributes

15
Researches in Informatics

• Are data really normally distributed?
• Bradfords Law, Lotkas Law, Zipfs Law, the
  Pareto Principle (the 80/20 Rule)
• Skew Distribution?
• Junk DNA shows Zipfs Distribution
• What does it mean?

16
Researches in Informatics

• Can we classify items according to their
  distribution?
• Libraries with the same usage pattern could be
  managed by the same methodology regardless of
  contents?
• Illnesses with the same occurring pattern may be
  handled by the same protocol regardless of their
  nature?

17
Questions and no Answer?

• What is Informatics?
• What is the purpose of Informatics?
• How do we know these purposes are correct? Are
  there better ones?
• What is healthcare (assuming that is what
  bio-informatics are for)?
• What is the purpose of healthcare?
