Backpack bends Doctor says save your back, use both straps
By Candy Niemann Special to the Kansan
Although the backpack seem innocent-looking, the symbol of collegiate life could be a health care provider, or, finally, a Lawrence cranium spacer.
Keith White, doctor of chiropractics at the Lawrence Chiropractic Center, 2711 W. Sixth St., said, "Carrying your pack on one shoulder definitely causes a problem. It is sad that society has inflicted so many students are more worried about them look than how they feel."
The campus fashion dictates that the backpack be carried using only one side of the backpack and severe strain on a student's back, as well as causing several other problems.
White said back problems could develop within a two-week period of carrying a backpack to class on a weekday and weighing more than five pounds.
White said tat several students a year complained about back problems but that the students didn't. Mr. Grabowski backpack was causing the problem.
The muscles on one side of the back stay contracted constantly, causing extra muscle development and buildup of acid in the tissues.
Muscles become knotted, White said, and the pack clamps down on

the lymph nodes, cutting circulation there as well as in blood vessels. A needle added strain on the neck and shoulder, pulling of vertebrae, headaches, numbness in the arm, pain in one in 1,000 cases, eye problem.
Kim Davis, Olathe senior, had noticed in herself some of the same symptoms White had seen in his patients.
"I was carrying more things
than usual in my backpack," she said. "My arm really started hurting, so I had to set my pack down on the sidewalk for a while. About an hour later, my arm became and my hand started shaking."
White said that students should pay attention to those symptoms.
"Normally, our bodies will tell us when there is a problem," he said. "We'll pack the pack is the nerdy way, over the shoulders, and no one wants to do that."
"I had a student who I told to start wearing the pack over both shoulders. I only do it sometimes, though, because when he did, he would get
Switching the pack from shoulder to shoulder can alleviate some of the problems, but White said it might really "the lesser of two evils."
Jim Foster, Mission junior, said that he carried his pack the correct way, crossing fashion lines because it was more convenient.
"When I was a freshman, I worried like everyone else did. The first time I got too much of a hassle. It feels like I have 800 books to carry with me."
Most students, however, continue to carry their loads on one shoulder.
Computer system could help farmers select crops to plant

Farmers may be able to use a computer to decide which crops to plant with a new program being developed by a KU graduate student,
Kyle Juracek, Omaha, Neb., doctoral student in geography, is the computer program to help farmers determine the profitability of crops.
Kyle Juracen, Omana, Neb., doctor student in geography, is developing the system using information about a farmer's land, equipment and economic status to determine the most practical and profitable crops.
"I's timely," urackee sun. "and farmers are in trouble, so it would be meaningful to them to have a sense of help them diversify their crops."
Juracek said the program would help farmers choose alternative crops — those that are outside the normal range of crops cultivated in the region. The central Great Plains and southern corn, sorghum, soybeans and wheat.
Alternative crops such as potatoes and asparagus can profitably grow in poor conditions but return because of low commodity prices, high interest rates and falling prices.
"A human could do the same things, but it takes longer and the chance of error is greater." Juracek
Juracek said he hoped that within 10 years, his system would be used as a tool for county agricultural extension agents.
He said the system would work quickly and accurately.
said.
Jack Lindquist, Douglas County agricultural extension agent, said that in most states, county extension centers tend to assist farmers. However, he said Jurackee would be different in economic and market information.
"It would really help speed up research," Lindquist said. "But it needs to be updated often. If one farm takes up a particular market, it will need to be moved the market left for a second farm, so it needs to be updated each time a farm
grows a crop."
To develop his program, Juracek is using a geographic information system that maps out the physical suitability of an area for a particular crop. Information is assembled about factors such as the length of the tree and the slope of the land and availability of nutrients, moisture and nutrients.
He also uses an "expert system" that analyzes the socio-economic situation. It includes the farmer's equipment needs, storage space, capital and labor availability market potential, and production.
