The speech intelligibility at the opera singing.

The authors investigated the speech intelligibility at opera singing. They analysed several arias sung by soprano voices from Czech opera "Rusalka" (The water Nymph), from Puccini's opera "La Boheme" and several parts of arias from "Il barbiere di Siviglia" sung by baritone, tenor, bass and soprano. The sonographic pictures of selected arias were compared with a subjective evaluation. The difference between both authors was about 70%. The opinion is, that the singer's formant is not the only one problem having its role in the speech intelligibility of opera singing. The important role is played by the ability to change the shape of vocal tract and the ability of rapid and exact articulatory movements. This ability influences the shape of transients that are important at the normal speaking and also in the singing.

Contribution of artificial intelligence to the knowledge of prognostic factors in laryngeal carcinoma.

Many studies have investigated prognostic factors in laryngeal carcinoma, with sometimes conflicting results. Apart from the importance of environmental factors, the different statistical methods employed may have influenced such discrepancies. A program based on artificial intelligence techniques is designed to determine the prognostic factors in a series of 122 laryngeal carcinomas. The results obtained are compared with those derived from two classical statistical methods (Cox regression and mortality tables). Tumor location was found to be the most important prognostic factor by all methods. The proposed intelligent system is found to be a sound method capable of detecting exceptional cases.

Intelligence is universal in life.

Behaviorists assume that living things memorize random atoms of information (engrams), "reinforced" by success, just as in the neo-Darwinian mutation-selection process. On the contrary we have to recognize the existence of organized and systematic responses in the learning process (Krechevsky). The animals seek desperately to "understand the meaning" of the world around them, by widening its context. Intelligence is not an exclusive prerogative of human mind. The minds of insects operate in the same way as that of man. Even a cell has a sort of intelligence (Cuenot). Consciousness is a state of awareness associated with enhanced mental activity. It occurs also in other "higher" animals (Thorpe). However human themselves are non conscious of their basic underlying motivations. Unconscious or ineffable knowledge plays a great role in shaping our world-view and in determining our influence on the Gaian hierarchy.

Expertise and age-related changes in components of intelligence.

In a sample of 263 male GO players at 48 levels of expertise and ranging from 18 to 78 years of age, it was found that factors of expertise deductive reasoning (EDR) and expertise working memory (EWM) were independent of factors of fluid reasoning (Gf) and short-term working memory (STWM) that, along with cognitive speed (Gs), have been found to characterize decline of intelligence in adulthood. The main effects of analyses of cross-sectional age differences indicated age-related decline in EDR and EWM as well as in Gf, STWM, and Gs. However, interaction and partialing analyses indicated that decline in EDR and EWM decreased to no decline with increase in level of expertise. The results thus suggest that with increase in factors known to raise the level of expertise--particularly, intensive, well-designed practice--there may be no age-related decline in the intelligence that is measured in the abilities of expertise.

[The theory of multiple intelligences: a suitable neurocognitive context for the neuropsychological hypotheses on the factors and mechanisms of superiority].

OBJECTIVES: The aim of this article is to relate two theories regarding the structure of the human mind. We suggest that the theory of multiple intelligences, a neurocognitive theory of the psychologist Howard Garnerd provides a suitable context for theoretical understanding and validation of the hypothesis of the pathology of superiority, a neuropsychological hypothesis formulated by the neuropsychologists Norman Geschwind and Albert Galaburda. Similarly, we show that, apart from being a context, the first theory enriches the second. DEVELOPMENT: We review the essential elements of both theories together with the arguments for them so that the reader may judge for himself. Similarly we review the factors determining intelligence; the association between neuropathology and intellectual dysfunction, general and specific, and the new directions in the understanding of human cognition. CONCLUSIONS: We propose to consider the first theory as a fertile ambit and broad methodological framework for investigation in neuropsychology. This simultaneously shows the relevance of including neuropsychological investigation in broader cognitive and neuropsychological theories and models.

[Effect of iodine intake on thyroid diseases and intelligence among schoolchildren in rural areas].

OBJECTIVE: To understand the throid function and intelligence among the schoolchildren in three rural areas with different iodine intakes in China to probe the side-effect of excessive iodine intake on intelligence of schoolchildren. METHODS: Chinese version of Raven's test was made among rural schoolchildren, 190 from Panshan County, Liaoning Province, a low iodine intake area with the median urinary iodine (MUI) of 99 microgram/L among its inhabitants, 236 from Zhangwu County, Liaoning Province, a moderate iodine intake area with the MUI of 338 microgram/L, and 313 from Huanghua County, Hebei Province, an excessive iodine intake area with the MUI of 631 microgram/L. Thyroid function, thyroid autoantibody (TAA), and MUI were determined among 116, 110 and 112 from the above-mentioned schoolchildren from these three areas respectively. RESULTS: There was no significant difference among the prevalence rates of overt hyperthyroidism, subclinical hyperthyroidism and overt hypothyroidism in the areas of Panshan, Zhangwu and Huanghua. However, a significant difference was found among the prevalence rates of subclinical hypothyroidism in theses three areas (P = 0.001). The prevalence rates of subclinical hypothyroidism in Huanghua and Zhangwu were 4.76 and 3.37 times higher than that in Panshan (P = 0.001). TAA was negative among all of the schoolchildren with subclinical hypothyroidism except for one. No significant difference was found among the positive rates of thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TGAb) in these three areas. Serum thyroglobulin (TG) values in Huanghua were markedly higher than those in the other two areas (P = 0.015 7). Serum TG value in Zhangwu was higher than that in Panshan but with no significant difference. The IQ value of the schoolchildren in Huanghua was markedly higher than that in Zhangwu (P = 0.001 2). The IQ value of the schoolchildren in Panshan was lower than that in Huanghua and higher than that in Zhangwu but with no significant difference. CONCLUSION: The increase of iodine intake may increase the risk of subclinical hypothyroidism among schoolchildren. In the area with excessive iodine intake, most of the subclicical hypothyroidism cases among schoolchildren are not of autoimmune origin. No obvious effect of excessive iodine intaue is found on mental development of schoolchildren.

[The multiple selection vocabulary test (MSVT-B)--an accelerated intelligence test].

A new accelerated intelligence test is presented which is known as the multiple selection vocabulary test B. This is a very objective and reliable test measuring the general level of intelligence. The time of testing will be about three to five minutes in the case of persons that are free of any psychiatric disorders. Test results will be only negligibly influenced by psychic and mental disorders.

[Changes in test norms of spelling achievement and nonverbal intelligence].

The norms of the spelling test R-T Form C "Moselfahrt" (Althoff et al. 1974) from the year 1968 and of the nonverbal intelligence test CFT 20 (form A/part 1) from the year 1977 (Weiss 1987) are evaluated for their actual validity. In 1995, both original tests were being administered to an epidemiological sample (N = 592) of adolescents and young adults in the age of 16 to 30 years having passed at least their obligatory amount of school years. These results are being compared to those of the original norm samples. Using the norms for the CFT 20 from 1977 adolescents and young adults achieve in the year 1995 a mean IQ of 110.8 points, equaling a yearly IQ-gain of 0.6 IQ-points. This exceeds the expected gain of 0.33 IQ-points annually according to the literature and indicates a distinct change of norms. There were no significant gender differences found. The distribution of mistakes in the spelling test R-T "Moselfahrt" compared to the original norm sample from 1968 changes considerably as well and requires revised test norms. With an increase from 9-11 mistakes (depending on the age norm) to 19.8 mistakes the mean amount of mistakes is almost being doubled. Extremely high numbers of mistakes occurred more frequent and could not be differentiated according to the old norms. Using the original norms from 1968 in the year of 1995 12.4% of the sample achieve with a T-score of 20 the lower limit of the measured value scale and the overall mean has decreased by 1.2 standard deviations to T-score = 38.48% of the sample reach a result that equates percentage 10 or less which is interpreted as insufficient school mark. Women's mean spelling achievement is significantly better than men's. Causes and implications of this scissors-like development of deteriorated spelling achievement and increased nonverbal intelligence are being discussed. Tables containing the new standardization scores are included in the appendix.

Emotional intelligence: its role in training.

The ability to manage your own emotions while interpreting other people's is a useful skill in any caring environment, yet emotional intelligence is often overlooked in training programmes. Incorporating it into the curriculum will give nurses greater understanding of themselves and the way they relate to others, enabling more effective interactions with patients. It will also equip them emotionally to deal with highly charged situations. The authors describe a model for nurse education that teaches and promotes emotional intelligence.

National intelligence estimate: the global infectious disease threat and its implications for the United States.

Infectious diseases are a leading cause of death, accounting for a quarter to a third of all deaths worldwide. The spread of infectious diseases results from both human behavior such as lifestyle choices, land-use patterns, increased trade and travel, and inappropriate use of antibiotic drugs, as well as mutations in pathogens. These excerpts from a January 2000 National Intelligence Estimate highlight the rising global health threat of new and reemerging infectious diseases. The National Intelligence Council argues that the infectious disease threat will complicate US and global security over the next 20 years. These diseases will endanger US citizens at home and abroad, threaten US armed forces deployed overseas, and exacerbate social and political instability in key countries and regions in which the US has significant interests, according to the report.

[The application and development of artificial intelligence in medical diagnosis systems].

This paper has reviewed the development of artificial intelligence in medical practice and medical diagnostic expert systems, and has summarized the application of artificial neural network. It explains that a source of difficulty in medical diagnostic system is the co-existence of multiple diseases--the potentially inter-related diseases. However, the difficulty of image expert systems is inherent in high-level vision. And it increases the complexity of expert system in medical image. At last, the prospect for the development of artificial intelligence in medical image expert systems is made.

Estimation of urban runoff and water quality using remote sensing and artificial intelligence.

Water quality and quantity of runoff are strongly dependent on the landuse and landcover (LULC) criteria. In this study, we developed a more improved parameter estimation procedure for the environmental model using remote sensing (RS) and artificial intelligence (AI) techniques. Landsat TM multi-band (7bands) and Korea Multi-Purpose Satellite (KOMPSAT) panchromatic data were selected for input data processing. We employed two kinds of artificial intelligence techniques, RBF-NN (radial-basis-function neural network) and ANN (artificial neural network), to classify LULC of the study area. A bootstrap resampling method, a statistical technique, was employed to generate the confidence intervals and distribution of the unit load. SWMM was used to simulate the urban runoff and water quality and applied to the study watershed. The condition of urban flow and non-point contaminations was simulated with rainfall-runoff and measured water quality data. The estimated total runoff, peak time, and pollutant generation varied considerably according to the classification accuracy and percentile unit load applied. The proposed procedure would efficiently be applied to water quality and runoff simulation in a rapidly changing urban area.

On the correlation of myopia and intelligence.

A pleiotropic relationship between intelligence and myopia has been shown to exist. Large eyes (as measured by axial length) have been shown to lead to myopia, and large brains have been shown to be more intelligent. I hypothesized that the myopia/intelligence relationship could arise because a single genetically controlled mechanism affects both brain size and eye size. This hypothesis has testable implications.

MIMIC II: a massive temporal ICU patient database to support research in intelligent patient monitoring.

Development and evaluation of Intensive Care Unit (ICU) decision-support systems would be greatly facilitated by the availability of a large-scale ICU patient database. Following our previous efforts with the MIMIC (Multi-parameter Intelligent Monitoring for Intensive Care) Database, we have leveraged advances in networking and storage technologies to develop a far more massive temporal database, MIMIC II. MIMIC II is an ongoing effort: data is continuously and prospectively archived from all ICU patients in our hospital. MIMIC II now consists of over 800 ICU patient records including over 120 gigabytes of data and is growing. A customized archiving system was used to store continuously up to four waveforms and 30 different parameters from ICU patient monitors. An integrated user-friendly relational database was developed for browsing of patients' clinical information (lab results, fluid balance, medications, nurses' progress notes). Based upon its unprecedented size and scope, MIMIC II will prove to be an important resource for intelligent patient monitoring research, and will support efforts in medical data mining and knowledge-discovery.

Effects of orofacial myofunctional therapy on speech intelligibility in individuals with persistent articulatory impairments.

This study examined the effects of orofacial myofunctional therapy (OMT) on speech intelligibility in adults with persistent articulation impairments. Six adults in the age range of 18-23 years were selected to receive orofacial myofunctional therapy for a period of six weeks. The results showed that five out of six clients made significant progress in oral postures and speech sound production across all three speech production tasks: single words, sentences, and spontaneous speech. Speech intelligibility increased significantly in all clients except the one diagnosed with developmental apraxia of speech. Orofacial myofunctional therapists, speech-language pathologists, and other professionals need to rule out underlying orofacial myofunctional variables when targeting speech sounds for intervention. Speech production tasks may be considered as important measures to understand the efficacy of OMT in clinical settings.

Wechsler Adult Intelligence Scale-third edition characteristics of a military traumatic brain injury sample.

This article describes the postinjury cognitive functioning of a sample of active duty, retired, and military beneficiaries who received traumatic brain injuries. Patients were seen in the neuropsychology clinic at Brooke Army Medical Center for a detailed cognitive and personality assessment. The scores on a major component of this evaluation, the Wechsler Adult Intelligence Scale, third edition, are summarized. The results are compared with those reported in the Wechsler Adult Intelligence Scale, third edition technical manual for a smaller, less diverse sample. The findings are consistent with the formulation that stable verbal skills are most resistant to brain injury, followed by nonverbal reasoning and visuospatial ability, and then working memory with speed of information processing being the most vulnerable to the effects of brain injury.

A general architecture for intelligent tutoring of diagnostic classification problem solving.

We report on a general architecture for creating knowledge-based medical training systems to teach diagnostic classification problem solving. The approach is informed by our previous work describing the development of expertise in classification problem solving in Pathology. The architecture envelops the traditional Intelligent Tutoring System design within the Unified Problem-solving Method description Language (UPML) architecture, supporting component modularity and reuse. Based on the domain ontology, domain task ontology and case data, the abstract problem-solving methods of the expert model create a dynamic solution graph. Student interaction with the solution graph is filtered through an instructional layer, which is created by a second set of abstract problem-solving methods and pedagogic ontologies, in response to the current state of the student model. We outline the advantages and limitations of this general approach, and describe it's implementation in SlideTutor - a developing Intelligent Tutoring System in Dermatopathology.
