Computers in medicine

A growing group of institutions and individuals use Internet connections to reach information sources. Large health care organizations now see electronic records as essential to providing cost-effective health care. The Visible Human Project represents the entire three-dimensional anatomy of a cadaver.     

Computers in dental education

The advent of electronic support for dental education offers many possible improvements in the manner in which information is conveyed to students. Although dental schools are only beginning to implement these concepts and devices, there is indication that they will become increasingly common. Concepts can be more lucidly conveyed when images and mulitmedia are used effectively. Distances can be transcended, and information gathered from and conveyed to others without regard to physical limitations. The dental school curricula must accommodate the changing milieu in which dentistry is practiced and prepare students for the future, electronically assisted dental practice.     

计算机在煤气柜上的应用

１前言煤气柜是大、中型钢铁企业常用的设施,它在贮存煤气、调节煤气管网压力、合理使用能源、减少环境污染等方面发挥着重要作用。但煤气柜一般采用常规仪表监视,由于常规仪表故障多,响应速度慢,使操作人员调节管网压力的波动相对滞后,阻碍了煤气柜功能的及时有效发挥。韶钢１９９９年５月建成投产的２台POC型干式煤气柜,采用了计算机对整个柜内的所有热工参数进行采集和处理,并在显示器上动态显示,使２台煤气柜的自动控制运行情况处于操作人员的监控之下,并对煤气柜的运行状态进行采集和显示;能对异常情况进行报警,便于操作…     

Computers in the medical practice

This article is part of a series covering the ever-expanding role of computers in the medical office and practice by Glenn L. Gordon, MD, FACIP. Dr. Gordon is Director, Center for Digestive and Liver Diseases, Clinical Instructor of Medicine at St. Louis University School of Medicine, President of Audrain County Medical Society, Immediate Past President of American Cancer Society-Audrain Unit, and State Council MSIM/ASIM Delegate. This is the first of a series of articles covering the expanding role of computers in our medical practice from office management programs to the Internet. This month's article covers the computerized medical record and what it can do for you.     

Application of Small Computers in Construction

The deliberations of the ASCE Task Committee on the Application of Small Computers in Construction are presented. The paper first identifies needs that are stimulating the application of small computers in construction, and then examines their present and potential utilization in several representative application areas. Applications include accounting and payroll, estimating, field office administration, contract language retrieval, electronic communications, scheduling, process simulation, graphical reporting, computer‐aided design, and process control. The role that ASCE might take in supporting the effective application of small computers in construction practice is considered. Possibilities include participation in the development of standards, education of practitioners, stimulation of innovative techniques, liaison with other organizations, input to computer manufacturers and software developers about specific needs and requirements in construction, studying the organizational and behavioral aspects of computers in construction, and input to ASCE awards committees about meritorious work in this area. It is concluded that an ongoing ASCE Construction Division committee is needed to monitor and influence the effective application of this rapidly evolving small computer technology in construction.

Computers: Large-scale usage in the balance.

Discusses the various and most recent uses of large-scale computer systems (i.e., those with high-speed core memories of 1-4 million bytes). Issues related to time-sharing, types of large system configurations (e.g., the Advanced Research Projects Agency network), specific applications to psychology of these computer systems (e.g., for statistical analysis, simulation, and instruction), and possible future uses (e.g., speech-understanding systems and simulation languages and systems) are outlined.

Mathematical Manslaughter by Electronic Computers.

The advent of electronic computers has been a boon far beyond the fondest dreams of the last generation's statisticians and psychometricians. Factorial analyses and other procedures, that would previously have been available only to the most advanced studies with strong financial support for the necessary computational manpower, are now within the reach of most master's theses. With these blessings, however, have come some evils. For one thing, it is no longer necessary to know more than the name of a statistic in order to utilize it. In addition, the electronic specialists themselves often cut corners to make computation feasible. But whether electronic computers become a blessing or a booby trap depends upon the care with which we watch for some of their inherent hazards.

Computers in home care. Application of change theory

BACKGROUND: Genetic testing for susceptibility to cancer often involves complex medical, ethical, legal, and psychological issues that present a challenge for physicians in clinical practice. METHODS: This study is based on survey data from 101 primary care physicians throughout Texas, measuring their interest in and attitudes about cancer genetics. RESULTS: The majority of physicians surveyed reported that they would consider genetic screening for at least one of seven genetic disorders that predispose to cancer, and almost 20% had made one or more referrals for genetic evaluation and DNA testing. Overall, they wanted to see a variety of continuing education programs and educational materials on DNA testing for cancer susceptibility developed. Although most of the physicians accurately perceived a number of major obstacles to referring patients for genetic testing, barriers such as difficulty in interpreting test results, potential for false-positive and false-negative results, and concern about patients'reactions to test results were reported less frequently. CONCLUSIONS: The results support other evidence for a need to provide continuing education to physicians about genetic testing for susceptibility to cancer.     

Advice for the ''90s traveler

There are controversial reports on the potential role of L-thyroxine administration as a risk factor for osteoporosis. We studied bone mass and metabolism in a homogeneous series of 50 Caucasian women, 25 premenopausal and 25 postmenopausal, having nontoxic goitre treated with slightly suppressive L-thyroxine doses (50-200 micrograms/day) with subnormal serum TSH and normal thyroid hormone levels. These patients were matched with 50 controls for age, sex, body mass index, menopausal and thyroid disease. Patients and controls were also investigated for minor determinants of bone loss, such as hereditary and life-style factors. Patients and controls filled in a questionnaire and underwent physical examination, routine laboratory tests and calciotropic and thyroid hormone assay. Bone mineral turnover was evaluated by determining serum osteocalcin, alkaline phosphatase, tartrate-resistant acid phosphatase, calcium, phosphate, urine hydroxyproline/creatinine and calcium/ creatinine ratio. Bone mineral density was measured by dual-energy X-ray absorptiometry at the lumbar spine, femoral neck, trochanter and Ward's triangle. No difference in bone mineral density or biochemical markers was found between patients and controls; bone density and turnover were significantly affected by menopausal status. No relationship between bone density or turnover values and L-thyroxine administration was found. A significant positive correlation was found between osteocalcin and the hydroxyproline/creatinine ratio in premenopausal and postmenopausal patients, but not in controls. Our study suggests that slightly suppressive L-thyroxine administration in nontoxic goitre can activate bone turnover but constitutes neither an actual risk factor for bone loss nor, consequently, for osteoporotic fractures.
