Wichita aircrash investigated
United Press International
WICHITA — A low-flying, singleengine airplane that crashed amid heavy fog and killed four men, including two prominent Republicans, plowed into trees before slamming into the ground, the sheriff said yesterday.
Those killed were George Van Riper of Wichita, 35, a former executive director of the state Republican Party, former state Rep. Donald A. Bell of Wichita, 57 Joseph E. Kreutzer, 33, owner of United Securities Inc. of Wichita, and the pilot, James D. Gass, 48, Wichita. Gass was a captain on the Sedgwick
County Fire Department.
Their Cessna airplane went down in dense fog shortly before 7 p.m. Tuesday as they returned from a business trip in metropolitan Kansas City, officials said.
City, officials said.
A survivor, Stephen Shogren, 35,
Wichita, crawled from the wreckage to the top of a ravine in a heavily wooded area, said Sedgwick County Sheriff Mike Hill. Shogren was in stable condition at Wesley Medical Center, officials said.
CENTER FOR JURISPRUDENCE
Van Riper was executive director of the state Republican Party from 1977 to 1979.
Bell, also a Republican, was a state representative from 1965 to 1970 and
House majority leader in 1969 and 1970. He was a municipal bond attorney and in partnership with former Sen. Norman Gaar of Westwood.
Representatives from the National Transportation Safety Board were investigating the crash, but Hill said preliminary findings made it clear to him the plane was flying close to the ground and struck some trees before slamming into the ravine.
It took searchers about 30 minutes to find part of the plane's wreckage in the wooded ravine. Shogren was found a few minutes later and told searchers there were four other people in the plane.
Patterns reveal disorders
Speech lab studies sounds
By John Williams Of the Kansan staff
Researchers in a small room tucked in the east wing of Haworth Hall aren't bothered by the sounds of children playing next door. Sound is their business.
The researchers work at KU's Applied Communicative Sciences Lab, one of two labs used by the department of speech-language-hearing; sciences and disorders, to find new information about all aspects of speech, Kim Wilcox, assistant professor of speech-language-hearing, said yesterday.
ASCL began last March as an idea, but within the past three months, the speech lab, with its modern equipment, has attracted attention from several programs, such as linguistics, music education and human development and family life. Wilcox said.
"One of the interesting aspects of the lab is the wide range of topics studied here," Wilcox said. "We have developed most of the work in three months time and we expect demand for the lab to grow more as the potential is realized by other departments."
The speech lab is used as a speech and hearing disorder clinic and for research dealing with speech and audiology, the study of sound.
audiology. Projects at ASCL involve voice patterns of stutterers, changes of speech due to normal aging, intonation in deaf speech and sounds made by strumming or picking a guitar.
Linguists also use the lab to analyze voice patterns in foreign languages, particularly Korean.
"We are all over the board here and we are flexible enough to switch it around to different things." Wilcox said.
Talking or sounds are recorded so a signal processing computer can analyze them, said Tony Seikel. Lawrence graduate teaching assistant. The speech laboratory also contains a spectrograph to measure the voice patterns and frequencies of a repeated word or sentence.
With the computer and spectrograph Wilcox, Seikel, and Makoto Kariyasu, Tokyo graduate student, manipulate sounds by chopping words up, adding sounds, switching positions of words or sounds, or eliminating some of the frequencies and making some sounds louder.
"We can see, or hear, when two similar sounds sound like each other and the minimal place where they differ," Seikel said. "With this information we can apply it to disorders in speech to see why some sounds different and how much deterioration can make a difference."
ASCL is studying the speech of people with amyotrophic lateral sclerosis, or Lou Gehrig's disease. Slowed speech is sometimes a sign of the disease.
By studying speech pattern of people with the disease, Seikel said, researchers may be able to offer a way to diagnose it earlier.
defense for possible neurological problems when older people come into the lab and say they have problems with their voice," Seikel said.
Sometimes we are the first line of
Wilcox, who is involved in the research on Lou Gehrig's disease with another group in Kansas City, Mo., said he was "spending time on the time dimensions" of speech because when speech breaks down, timing is usually involved.
Wilcox said ASCL's computer could detect differences in speech if the timing was off by only two or three milliseconds.
"It can't be detected by the human ear, but the computer can distinguish the difference, helping in early diagnosis," he said.
seikel said that the computer could break speech down into time increment of a 20 thousandth of second and that the lab was working toward smaller time increments of one 40 thousandth of a second. The more samples the computer has to work with, the more accurate the analysis can be.
The lab is also working on a project in conjunction with the department of human development and family life. The project will analyze the differences among voices of parents talking to children when they play with dolls and when they play with trucks.
