The Weed system is an orderly identification of patient problems, interventions guided by these problems, an systematic documentation of more or less effective solutions. We outline our attempts to modify this system in a manner to retain these essentials while increasing acceptance by staff in a psychiatric unit of a ...

Numbers play a great role in our practice of laryngology, and when used appropriately can be extremely valuable. However, careless or uncritical use may cause them to be an impediment of detriment to clinical practice and teaching. Examples of problems which arise with numbers are readily found in the areas ...

Concern with the provision of health and welfare services to underserved or inappropriately served groups has led to numerous studies of patterns of service utilization. This article focuses on the help-seeking patterns of heroin-addicted and nonaddicted women of lower socioeconomic status. The results suggest addicts generally experience more problems than ...

The otolaryngologist frequently encounters problems related to the form and function of the stomatognathic system. Much has been published over the past 50 years regarding the "ideal occlusion," but controversy continues to rage over the relevance of various occlusal parameters to the evaluation and management of problems involving occlusal dysfunction. ...

During a disaster drill at Detroit-Wayne County Metropolitan Airport in September 1978, an attempt was made to evaluate the effectiveness of triage by tracing the routes of "victims" using a system of tracking cards. The cards were placed with the victims during make-up and collected at the receiving treatment facility. ...

Patients for whom there is no appointment who ask to be seen on the same day can be a source of irritation. During March 1978, 214 of these patients were compared with 749 who made appointments. No evidence was found that such patients were abusing the system, and almost half ...

Acoustic, somatosensory and visual evoked potentials were mapped in the suprasylvian gyrus of the cat during pentobarbital or chloralose anaesthesia or during subsequent application of both anaesthetics. In chloralose anaesthesia both parietal association areas (AMSA, PMSA) are easily recognized. Under pentobarbital anaesthesia, however, no activity is detectable in PMSA, while ...

The MEDLINE training course organized for users was based on the experience acquired by IMA from problem encountered in the user/system concerning: (a) The understanding of a computerized documentation system and its capabilitiesd. (b) The role of the computer, often over-estimated. (c) The user-search analyst interface, i.e. the role of ...

Most change implementation efforts focus on the initial acquisition-of-skill phase with little attention to maintaining skills in use of a new system. This article looks at the maintenance phases in implementing a new system, using a changeover to problem-oriented recording as an example. Through this illustration, the essential elements for ...

Fast IR wave-front aberration sensors are essential to the improved performance of HEL systems. However, one must not transfer sensor designs which function well (in principle and in practice) for the incoherent blackbody realm over into the coherent environment without first considering possible interference problems. A case history of one ...

The evolution of radiation protection philosophy over the past thirty years calls attention to an urgent need to review and revise current radiation control programs with respect to the ethical problems and priorities they reflect. One problem is the environmental crisis-mentality escalating already rising expectations in our affluent society about ...

The paper contains the main objections of foreign specialists (Llewellyn and others) to Bykhovsky's system of monogeneans. Llwellyn's interpretation of anchors and marginal hooks which is the basis of his phylogenetic scheme is proved to be erroneous by a number of data on morphology of chitinoid formations and on their ...

The Weed problem-oriented medical record has been modified for use in a state psychiatric hospital that has a large proportion of long-term patients and uses an interdisciplinary team approach to treatment. Three new record forms were developed during a pilot study at the hospital: the processed-problem list, the problem card, ...

Work on cochlear prostheses for the auditory rehabilitation of the profoundly deaf represents a challenging problem. Some early, but perhaps premature, surgical attempts have helped to bring the entire issue into focus. Systemic studies are now under way in many different places. Although the purely engineering problems as well as ...

An examination of the work dealing with dichotic listening reveals that technical problems prevent clear interpretation of the data. One of the most crucial problems is that of achieving simultaneity of output so that dichotic (simultaneous but different) material is introduced into the auditory system. A simple method for achieving ...

Over a one-year period, the York Hospital customized and refined an existing software package and developed a computerized hematology system which solved many of the problems encountered while implementing the computer in the routine hematology laboratory. These problems included: developing an efficient system of internal organization and work flow patterns; ...

Problems related to the measurement of spectral sensitivity distribution are discussed. Special systems, an electromechanical one with servo-control and an all-electronic one using an instantaneous value measuring ratiometer, have been built and their performance tested. A number of problems generally encountered in such measurements can be eliminated by using the ...

The empirical study of impossible figures requires that independent variables be well-specified. This paper provides an aid for such a task by developing a classification system which partitions cornered torus figures into meaningful subsets. These can be used to identify both formal and psychological properties of known as well as ...

When lower extremity lymphedema is not amenable to control by medical methods, attempts to ameliorate the problem surgically have generally been unsatisfactory. The intact testis and spermatic cord provide a potential bridge that may permit communication between the unobstructed lymphatics of the gonadal system and the obstructed lymphatics of the ...

The gray scale display used in B scan ultrasonography limits the perceptibility of clinically useful information. Presentation in color can increase perceptibility, but current color displays have no natural scale and may have the fault of a discrete color spectrum. The continuous heated-object color spectrum solves these problems. To produce ...

This study was designed to investigate the acoustic response of ten body-type hearing aids when used with an induction loop amplification (ILA) system in the laboratory and in the actual classroom setting. Undesirable frequency response characteristics were discovered in the classroom ILA system used in this study. These consist of ...

This study was designed to investigate the intelligibility of speech transduced through a classroom-installed FM system and a conventional induction loop amplification (ILA) system and to examine the applicability of an FM adapter when used with commercially available hearing aids. Findings indicate that speech reproduced via the FM system is ...

A review of the problems encountered in serials control systems is followed by a description of some of the present-day attempts to solve these problems. Specific networks are described, notably PHILSOM (developed at Washington University School of Medicine Library), the UCLA Biomedical Library's system, and OCLC in Columbus, Ohio. Finally, ...

It is unlikely that any serious attempt will be made to standardize bacterial nomenclature on a national or international scale until the implementation of the proposed revision of the International Code of Nomenclature of Bacteria on 1 January 1980. In the meantime, the lack of such standardization poses major problems ...

At present the main trends among the most important problems of otorhinolaryngology in space medicine have become defined as vestibulology, audiology and clinical aspects (prophylaxis, diagnosis and treatment of ENT diseases in flight). The principal result of recent vestibular studies has probably been the establishment of an apparent relationship between ...

The Lawrence Livermore Laboratory Octopus network includes a central storage facility of over 10-12 bits. This facility is accessed through a directory mechanism which permits flexible organization and general sharing of files by many time-sharing users. The chief problems of the system are not unusual: the maintenance of high transfer ...

The clinical symptoms of botulinum intoxication suggest that besides the involvement of the peripheral nervous system, the central nervous system is also affected. Studies were undertaken to determine whether pure toxin of Clostridium botulinum type A could be demonstrated in the brains of poisoned mice. With the aid of autoradiography ...

A good record system is fundamental to good care. The problem-oriented approach provides a scientific format for identifying and recording the course of a patient's problems. Starting with a defined data base, the physician formulates a complete problem list and initial plans of management. The progress notes record the feedback ...

This note introduces a new mathematical tool, nonstandard analysis, for the analysis of an important class of problems in mathematical economics-the relation between bargaining and the competitive price system.

Any two-dimensional interpolation scheme which has continuous derivatives may be used to represent an optical surface for ray-tracing purposes. We present bicubic splines in their application to the design of asymmetric surfaces. An as example of a problem requiring an asymmetric system, we analyze the design problems of a color ...

Recent technologic advances demonstrate that the morphologic approach to the nosologic delineation of nervous system disorders is often inadequate. This tenet is exemplified by the hopeless confusion which neuropathology has imparted on the problem of amaurotic familial idiocy. The delineation of nosologic entities involving the nervous system may depart from ...

The cerebellum presents the best site in the central nervous system for defining fundamental problems concerning the origin and differentiation of neurones, and their growth and development. The many recent experimental investigations of these problems are reviewed, and hypotheses based upon them are developed in relation to neurogenesis, morphogenesis, and ...

PURPOSE: In vocational rehabilitation, the selection and tailoring of the work place is tightly bound with the integration or reintegration of people with disabilities into the work environment. Instruments which ease this task are assessment systems as well as information systems of technical aids. To date, these instruments are separated ...

The earliest-known bats are represented by excellent fossil material, including virtually complete skeletons of Icaronycteris index from the early Eocene (50 Myr BP) of western Wyoming and Palaeochiropteryx tupaiodon from the middle Eocene (45 Myr BP) 'Grube Messel' of western Germany. These taxa have been closely allied with Recent Microchiroptera, ...
