...Suntans and Sunburns
A CaseStudy in the IntegumentarySystem
By WH Cliff and AW Wright
A Painful Winter Break
On the first day after arriving in Australia for Christmas vacation, a University of Niagara student plays out in the sun for six hours. Later that night he notices that the skin on his trunk, legs and arms becomes red, swollen and extremely painful. By morning all of the afflicted areas have developed numerous blisters. These areas cover about 30% of the trunk (front and back) and 40% of the arms and legs.
1. What organ has been damaged?
2. What general types of tissue have been afflicted?
Stratified Squamous Epithelium in the epidermis, Areolar Connective Tissue, and some Dense Irregular Connective Tissue in the dermis have been afflicted.
3. What type of burn has the student received? Explain.
2nd Degree Burn – Because of the blisters and severe pain.
4. What type of radiation has caused the burn?
5. List ALL the layers of the skin that have been damaged?
Epidermis (stratum corneum, stratum granulosum, stratum spinosum, stratum basale) and the upper region of the Dermis (papillary layer)
6. List ALL layers that have been killed?
No layers have been killed, just damaged.
7. What tissue repair process causes the blistering?...

Part I—"Soaking Up the Sun" Questions
1. What are some differences between Judy and Mariah that might make Judy more "at risk" for skin cancer than Mariah? (2 points)
Judy is described to have pale pasty white skin and red hair. Mariah is described to be a Greek goddess.
Judy’s skin is more prone to burning in the direct sun light due to her body not making as much melanin making her skin more reflective to light as where Mariah’s skin absorbs more light due to her body making more melanin giving her a tanner appearance.
2. What observations did Judy make concerning her mole? How could they have used the ABCDE’s of skin cancer assessment to further assist their observations? (2 points)
Judy states the site is itching- it never was in the past. That the mole appears bigger and raised dot in the middle with jagged edges and color changes.
A- The mole has changed shape
B- Jagged edges
C- Three colors in the mole
D- The mole was larger than before
E- Raised in the middle
F- Just by knowing these simple rules it would have told the girls that there was concern about skin cancer.
3. Should Judy be concerned? Why or why not? (2 points)
Yes, Judy should be concerned. Any skin changes can mean something is going on inside the body. It is the warning sign that your body give you.
Part II—"The Basics of Cancer" Questions
1. Considering the differences between a benign...
...some normal circumstances where our bodies might need to make more cells? Why is the skin continuously replacing its main cell and what specific damages to the skin would there be a need to make more cells? (3 points) Normal circumstances in which we need to make more cells would be body growth, or daily living. Our body is constantly migrating cells from the lowest layer to the superficial layer where our skin is replaced every 4 weeks or so. We need skin cells constantly made to replace our outer layer. A specific damage would be a burn, any burn in which skin cells would have to replace the ones that were burned off or damaged.
6. Every person has these cell cycle proto-oncogenes, but not every person has cancer. Why might this be the case? (3 points) Because the cells are not producing proteins to promote cell division that are active all the time.
7. Now that you know a little more, what are the risk factors that increase a person's chances of having melanoma? Besides the ABCDE’s, what other signs/symptoms can melanoma present with on a patient? (2 points) If you develop new moles, if they bleed, or if they become tender or painful.
8. How does sunlight contribute to the development of melanoma? (2 points) UVA radiation damages the DNA in human melanocyte cells, causing mutations that can lead to melanoma. Melanocytes, which contain a substance called melanin that darkens the skin to protect it from the ultraviolet rays of the sun, are more...

Suntans and Sunburns: A CaseStudy in the IntegumentarySystem
Many people do not realize that UV rays such as the sun can be severely harmful. In this particular case a student on vacation in Australia played Frisbee in the sun for six hours. Later on that night his skin on his trunk, arms, and legs has become red, swollen, and painful. The next day blisters have formed on the burnt skin. In this students case the skin on his trunk, arms, and legs have been damaged severely. This casestudy researches the diagnosis of the burns and the important aspects of the Integumentarysystem relating to burns and the correct treatment the student should be receiving.
The diagnosis of the student is that he has received second degree burns on his trunk, arms and legs. This is evident from the redness of the skin, the blisters that have formed, and the severe pain. The burns are not third degree due to the lack of widespread thickness with white leathery appearance and the skin is not charred black (Mayo clinic staff, Burns: First Aid)*. A second degree burn is an injury that has occurred from excessive heat penetrating the skin. This type of burn involves damage to the epidermis and into the upper region of the dermis. Due to this type of burn the...

Scenario 3 5 Marks
Your furniture company wants to create a data warehouse where management can obtain a single corporate-wide view of critical sales information to identify best-selling products in specific geographic areas, key customers, and sales trends. Your sales and product information are stored in several different systems: a divisional sales system running on a UNIX server and a corporate sales system running on an IBM mainframe. You would like to create a single standard format that consolidates these data from both systems. The following format has been proposed.
PRODUCT_ID PRODUCT_DESCRIPTION COST_PER_UNIT UNITS_SOLD SALES_REGION DIVISION CUSTOMER_ID
The following are sample files from the two systems that would supply the data for the data warehouse:

In this case we get an entire scenario about how the Japan deflation set in, what were the effects of the deflation on the economy as well as on the people of Japan. It also mentions about the various reasons because of which Japan was in such a tight grip of Deflation, Depression, Demographics and Debts Guides us through the steps taken by the government in order to curb this deflation. Imparts a great knowledge to us about the various economic terms like deflation, self-liquidating credit, Non-Self Liquidating Credit and how the people and economy of a country is affected by these.
Free markets economies are subject to cycles. Economic cycles consist of fluctuating periods of economic expansion and contraction as measured by a nation's gross domestic product (GDP). The length of economic cycles (periods of expansion vs. contraction) can vary greatly. The traditional measure of an economic recession is two or more consecutive quarters of falling gross domestic product. There are also economic depressions, which are extended periods of economic contraction such as the Great Depression of the 1930s.
From 1991 through 2001, Japan experienced a period of economic stagnation and price deflation known as "Japan's Lost Decade." While the Japanese economy outgrew this period, it did so at a pace that was much slower than other industrialized nations. During this period, the Japanese economy suffered from both a credit crunch and a liquidity trap....

...February of 1999. In the past four months, the NC design had developed
sustainability. The Bostrom alliance agreement for the truck market had been concluded. The
question about Elio's strategy for the entry into automobile still remained. Should Elio's joint
venture with Bostrom? Should it partner with a tier-one or a tier-two automotive supplier?
Was Elio's technology strategy aligned with the requirements for a successful entry into the
automotive market? Paul and Hari realized that they needed answers to these questions in
the coming days.
This casestudy discusses the start-up, origins and strategic options facing an innovative set up
and start up in automotive market and in the seat design. With the domination of the
incumbent large suppliers serving the top 3 leading tier-one automakers of U.S.,
Engineering faces several challenges as it seeks to introduce its new seating technology to the
market. The case can serve as vehicle to discuss important themes such as technology and
business strategy, invention and innovation, bringing technology to market and profiting from
Elio's should make a joint venture with Bostrom. Elio's has made a seat design naming "No
Compromise" with progress on cost, weight and performance compared to the conventional
design and also the existing all-belt-to-seat (ABTS). After many functional prototypes and
computer aided structural analysis, a perfect design...
