An Analysis of the Hoarse Speech Signals by the Three Mass Model of Vocal Cords *

A three mass model of vocal cords as well as mathematical expression of the model are discussed. Different kinds of typical hoarse speech due to laryngeal diseases are simulated on microcomputer and the effects of different pathological factors of vocal cords on model parameters are studied. Some typical spectrum distribution of the simulated speech signals are given. Moreover, hoarse speech signals of some typical cases are analyzed by the methods of digital signal processing, including FFT, LPC, Cepstrum technique, Pseudocolor encoding, etc. The experiment results show that the three mass model analysis of vocal cords is an efficient method for analysis of hoarse speech signals.

Quality prediction of batch process using the global-local discriminant analysis based Gaussian process regression model

The conventional single model strategy may be ill- suited due to the multiplicity of operation phases and system uncertainty. A novel global-local discriminant analysis （GLDA） based Gaussian process regression （GPR） approach is developed for the quality prediction of nonlinear and multiphase batch processes. After the collected data is preprocessed through batchwise unfolding, the hidden Markov model （HMM） is applied to identify different operation phases. A GLDA algorithm is also presented to extract the appropriate process variables highly correlated with the quality variables, decreasing the complexity of modeling. Besides, the multiple local GPR models are built in the reduced- dimensional space for all the identified operation phases. Furthermore, the HMM-based state estimation is used to classify each measurement sample of a test batch into a corresponding phase with the maximal likelihood estimation. Therefore, the local GPR model with respect to specific phase is selected for online prediction. The effectiveness of the proposed prediction approach is demonstrated through the multiphase penicillin fermentation process. The comparison results show that the proposed GLDA-GPR approach is superior to the regular GPR model and the GPR based on HMM （HMM-GPR） model.

A quasi-synoptic interpretation of water mass distribution and circulation in the western North Pacific:I.Water mass distribution

With high-resolution conductivity-temperature-depth （CTD） observations conducted in Oct.-Nov. 2005, this study provides a detailed quasi-synoptic description of the North Pacific Tropic Water （NPTW）, North Pacific Intermediate Water （NPIW） and Antarctic Intermediate Water （AAIW） in the western North Pacific. Some novel features are found. NPTW enters the western ocean with highest-salinity core off shore at 15°-18°N, and then splits to flow northward and southward along the western boundary. Its salinity decreases and density increases outside the core region. NPIW spreads westward north of 15°N with lowest salinity off shore at 21°N, but mainly hugs the Mindanao coast south of 12°N. It shoals and thins toward the south, with salinity increasing and density decreasing. AAIW extends to higher latitude off shore than that in shore, and it is traced as a salinity minimum to only 10°N at 130°E. Most of the South Pacific waters turn northeastward rather than directly flow northward upon reaching to the Mindanao coast, indicating the eastward shift of the Mindanao Undercurrent （MUC）.

Effects of Different Flue-curing Barns on Aroma Quality of Upper Flue-cured Tobacco Leaves of K326

[Objective] This study was conducted to compare the aroma quality of up-per leaves of K326 flue-cured in different barns, and provide theoretical references for the development and optimization of bulk curing barn and the supporting tech-niques. [Method] The upper leaves of K326 were flue-cured in a commonness barn, a four-shelf bulk curing barn and a three-shelf bulk curing barn separately, and then the contents of aroma components and taste quality indices of the finished leaves were measured and compared. [Result] The contents of total aroma components, chromoplast pigment degradation products, phenylalanine aroma components and neophytadiene showed no significant differences in the leaves flue-cured in four-shelf bulk curing barn and commonness barn, but were significantly or very significantly higher than those in the leaves flue-cured in three-shelf bulk curing barn. The con-tents of carotenoid degradation products, Mail ard reaction products, cembranes aro-ma components and total aroma components （except neophytadiene） showed no significant difference among the three treatments. The results of sensory evaluation revealed that the sensory taste of the leaves flue-cured in four-shelf bulk curing barn was the best, as the finished leaves had rich, delicate aroma, comfortable and clean aftertaste. The leaves flue-cured in commonness barn was better than those flue-cured in three-shelf bulk curing barn in aroma quality, amount and aftertaste. [Conclusion] The four-shelf bulk curing barn had a large volume for tobacco leaf processing, but a similar baking environment to the commonness barn, which is conducive to the formation and accumulation of aroma components, so the finished leaves had similar appearance and quality with those flue-cured in commonness barn. The upper flue-cured leaves in three-shelf bulk curing bran had poorer quality than those flue-cured in the other two barns.

Quality of Accounting Information and Internal Audit Characteristics in Nigeria

The basic goal of accounting is to provide quality accounting information that will aid reliable decision-making. The quality level of this accounting information comes from the company＇s governance practices, thereby emphasizing the importance of corporate governance in companies. Recently, following the financial crises resulting in accounting scandals, attention has been moving towards internal audit function as an important factor in the structure of corporate governance. This paper therefore examined the extent of the relationship between internal audit function and the quality of accounting information of companies. The study adopted the survey research design. The research instrument employed was questionnaire which was administered to internal auditors of the ＂Big Four＂. Linear regression analysis was employed in the analysis of the data collected with the use of Statistical Packages for Social Sciences （SPSS）. The results revealed that there is a significant relationship between the internal audit characteristics and the quality of accounting information. It was recommended that in order to provide credibility to the financial statement, there should be a law in place mandating attachment of internal auditors report to the financial statement.

Topographic Indices and Yield Variability in a Rolling Landscape of Western Canada

Understanding the relationships between topographic indices and crop yield variability is important for soil manage- ment and crop production in rolling landscape. Two agricultural fields at Alvena and Hepburn, Saskatchewan, Canada were selected to examine how topographic indices were related to wheat yield under two topographic and weather conditions in the Canadian prairies. The landscapes of the two sites are classified as hummocky and the dominant soil type is an Aridic Ustoll. The relationships among yield, topography, soil, and weather were analyzed using wheat (Triticum aestivum L.) grain yield from Alvena in 2001 (dry year) and 2004 (wet year) and from Hepburn in 1998 (dry year). Topographic/soil indices included relative elevation, wetness index, upslope length, curvature, soil organic matter, and soil moisture storage before seeding. The results indicated that, in the dry years, the correlation coefficients between upslope length and grain yield were 0.79 for the typical rolling landscape (Alvena) in 2001 and 0.73 for shallow gentle rolling landscape (Hepburn) in 1998. In the wet year (2004), the relationships between yield and topographic/soil attributes were not as strong as in dry years. Therefore, upslope length was the best yield indicator for the two landscapes in dry years, whereas no topographic indices were highly correlated to crop yield in wet years. Those topographic indices seemed useful in identifying the yield variability and delineating the proper management zone.

Research on psychological factors which influence Doctor-Patient communications among outpatients

This article, from the perspective of psychology, investigates into the common psychological factors which affect the Doctor-Patient communication, the appearance of the communication problem, and make suggestions on possible solutions accordingly.

Effect of Biofertilizer on Growth, Productivity, Quality and Economics of Rainfed Organic Ginger （Zingiber officinale Rosc.） Bhaisey cv. in North-Eastern Region of India

Ginger yields in the NorthEastern region of India are low because the extremely poor farmers of the region can not afford to apply any chemical fertilizers and hence apply only the locally-available farmyard manures to ginger fields. Biofertilizers may be a cheap source of fertilizers for ginger cultivation as they can increase nutrient availability and improve rhizome quality and are required in small quantity. An investigation was thus undertaken to study the effect of different biofenilizers on growth, productivity, quality and economics of organic ginger grown under rainfed condition in NorthEastern region of India. Seed treatment with biofertilizers enhanced growth, increased rhizome yield by 19.0% and resulted in 32.4% higher net profit over control. Among the seed treatments, Azotobacter 5.0 kg ha＂l, Azospirillum 3.75 kg hal and Phosphotica 3.75 kg ha-1 were found optimum in improving most of the growth attributes, increasing yield components and yield of rhizome by 5.6%-13.5%. They also improved rhizome quality by increasing specific gravity, oleoresin and dry matter content and by decreasing crude fibre in rhizome. They resulted in higher net return by 4.0%-12.0% as compared to their other levels. Combined use of Azotobacter 5.0 kg hal along with Phosphotica 3.75 kg ha＂l was found to be the best treatment combination which greatly improved growth and yield attributes of ginger and ultimately recorded markedly higher productivity （2.0%-23.5%） over other combinations. This treatment combination improved the quality of the produce and resulted in the highest gross return （$4,905 hal）, net return （$3,525 hal） and return per dollar （3.55） invested in ginger cultivation. It appears that growing organic ginger by treating the seed rhizome with Azotobacter 5.0 kg ha-~ along with Phosphotica 3.75 kg ha-1 can result in good growth and high productivity of improved quality rhizome and ultimately result in maximum net profit and thus can be recommended for the NorthEastern region of India.

Ecosystem service delivery in Karst landscapes： anthropogenic perturbation and recovery

Covering extensive parts of China, Karst landscapes are exceptional because rapid and intensive land use change has caused severe ecosystem degradation within only the last 50 years. The twentieth century intensification in food production through agriculture has led to a rapid deterioration of soil quality, evidenced in reduced crop production and rapid loss of soil. In many areas, a tipping point appears to have been passed as basement rock is exposed and 'rocky desertification' dominates. Through the establishment of the "Soil processes and ecological services in the karst critical zone of SW China"(SPECTRA)Critical Zone Observatory(CZO) we will endevaour to understand the fundmental processes involved in soil production and erosion, and investigate the integrated geophysical-geochemical-ecological responses of the CZ to perturbations. The CZ spans a gradient from undisturbed natural vegetation through human perturbed landscapes.We seek to understand the importance of heterogeneity insurface and below-ground morphology and flow pathways in determining the spatial distribution of key stocks(soil,C, vegetation, etc.) and their control on ecosystem service delivery. We will assess the extent to which the highly heterogeneous critical zone resources can be restored to enable sustainable delivery of ecosystem services. This paper presents the CZO design and initial assessment of soil and soil organic carbon stocks and evidence for their stability based on caesium-137(^(137) Cs) data.

Some important scientific problems in current lithospheric physics research in China

China has achieved much during recent years in the area of lithospheric physics research and promoted the development of the geosciences （Teng, 2004）. However, in the 21^st century, national needs and policy challenges the science of lithospheric physics. I suggest a general analysis, research, and development direction for lithospheric physics and point out clearly the content, core problems, and key scientific problems in this field. The realization of the earth and the discovery of the basic mechanisms of mountains, basins, minerals, and natural disasters depend basically on high-resolution observations of geophysics, the delineation of the fine structure of crust and mantle （2D and 3D） inside the lithosphere, substance and energy exchanges in the deep earth, the process of deep physical, mechanical, and chemical actions, and deep dynamical response. Therefore, geophysics should be the pioneer in the geosciences field in the first half of the 21^st century. I end with an analysis and discussion of some problems and difficulties in the research of lithospheric physics.

Judgment of Aroma Types of Middle and Upper Flue-cured Tobacco Leaves Based on Stepwise Discriminant Analysis

[Objective] The aim of this study was to establish mathematical models for judging the aroma types of middle and upper flue-cured tobacco leaves according to the contents and proportions of aroma compositions. [Method] The aroma types of tobacco leaves were judged based on stepwise discriminant analysis, using 63 C3F and 65 B2F tobacco leaf samples from 13 tobacco producing regions in 11 provinces of China （Huili in Sichuan, Baokang in Hubei, Wulong in Chongqing, Lu- oyang in Henan, Zhucheng in Shandong, Wuyi Mountain in Fujian, Malong in Yun- nan, Chuxiong in Yunnan, Bijie in Guizhou, Liuyang in Hunan, Suiyang in Guizhou, Kaiyuan in Liaoning, Nanxiong in Guangdong） as calibration samples, and 67 aroma components as indices. And the Fisher discriminant functions were verified using 21 C3F and 19 B2F tobacco leaf samples. [Result] Variation coefficients of the propor- tions were lower than that of contents of most aroma components in middle and upper leaves of the samples, indicating that the proportions were more stable than contents of aroma components. The proportions of benzyl alcohol, solanone, β-dam- ascone, neophytadiene, farnesylacetone A, palmitic acid, thunbergol, methyl linole- nate and cembratriene-diol were all over 1% in both middle and upper leaves, al- though the dominant aroma components of the same aroma type varied between middle and upper leaves. Moreover, 11, 18, 7 and 11 aroma components were re- spectively introduced into the Fisher discriminant functions established based on the contents and proportions of middle and upper flue-cured tobacco leaves, which ex- hibited accuracy rates of 91.7%, 100%, 91.7% and 91.7% in the judgments of other tobacco leaf samples. The results revealed that the components those determined aroma types in middle leaves were obviously more than in upper leaves. In middle leaves, the accuracy rates of aroma type judgment could be improved by using the proportions rather than the contents of aroma components as indices. However, the functions based on the proportions and the contents of aroma components in upper leaves gave close accuracy rates. [Conclusion] The results of the study will provide references for identifying aroma types of flue-cured tobacco leaves in future work.

Elevation, Slope Aspect and Integrated Nutrient Management Effects on Crop Productivity and Soil Quality in North-west Himalayas, India

On farm bio-resource recycling has been given greater emphasis with the introduction of conservation agriculture specifically withclimate change scenarios in the mid-hills of the north-west Himalaya region（NWHR）. Under this changing scenario, elevation, slope aspect and integrated nutrient management（INM） may affect significantly soil quality and crop productivity. A study was conducted during 2009-2010 to 2010-2011 at the Ashti watershed of NWHR in a rainfed condition to examine the influence of elevation, slope aspect and integrated nutrient management（INM） on soil resource and crop productivity. Two years of farm demonstration trials indicated that crop productivity and soil quality is significantly affected by elevation, slope aspect and INM. Results showed that wheat equivalent yield（WEY） of improved technology increased crop productivity by -20%-37% compared to the conventional system. Intercropping of maize with cowpea and soybean enhanced yield by another 8%-17%. North aspect and higher elevation increased crop productivity by 15%-25% compared to south aspect and low elevation（except paddy）. Intercropping of maize with cowpea and soybean enhanced yield by another 8%-15%. Irrespective of slope, elevation and cropping system, the WEY increased by -30% in this region due to INMtechnology. The influence of elevation, slope aspect and INM significantly affected soil resources（SQI） and soil carbon change（SCC）. SCC is significantly correlated with SQI for conventional（R2 = 0.65＊）, INM technology（R2 = 0.81＊） and for both technologies（R2 = 0.73＊）. It is recommended that at higher elevation.（except for paddy soils） with a north facing slope, INM is recommended for higher crop productivity; conservation of soil resources is recommended for the mid hills of NWHR; and single values of SCC are appropriate as a SQI for this region.

Evaluation of the Nutritional Supplement VIUSID Vet Powder on the Productive Behaviour of Sows and Boars

The objective of this research was to evaluate the effect of administering VIUSID vet powder on the productive behaviour of sows and the quality of semen of boars. Two experiments were conducted on farms in the province of Sancti Spiritus, in the central region of Cuba. One was with sows, starting 21 days before parturition until weaning, and another was with boars in directed mounting. Each sow received 10 grams of VIUSID vet powder everyday, mixed with food, from 21 days before the probable date of farrowing and until weaning （33-day lactation period）. In the boars, the treatment consisted of administering 10 grams of VIUSID vet powder with feed, once a day for 6 weeks （week 1 to 6）; from week 7 onwards, the supplement was suspended. Results showed that, supplying VIUSID vet powder significantly improved the principal post-partum productivity indicators and significantly reduced diarrhoea and administration to boars in production for 6 weeks, which has improved spermatic motility and does not affect the other variables representative of the quality of the semen.

Labor Quality, Labor Utilization Efficiency and Economic Development： Regional Discrepancies and Solutions＊

This paper presents the results of our experiments to assess average labor quality and labor force utilization in different regions of China using slack-based inefficiency measurement （SBI）. We found that there is a discrepancy between different regions＇ labor resources and their stages＇ of economic development. In central and western regions, the average quality of labor is significantly higher than in eastern regions, but labor force utilization is less efficient. Slow in economic growth and laggard in industrial upgrading, central and western regions have failed to provide their high-quality labor forces with adequate and suitable job opportunities, leading to the discrepancy between labor resource quality and economic development. Resolving this discrepancy might help coordinate economic development across different regions in China.

A New Method for Measurement of Local Solid Flux in Gas-Solid Two-phase Flow

Previous works have shown that the suction probe cannot be used to accurately measure the upward and downward particle fluxes independently. A new method using a single optical probe to measure the local solid flux is presented. The measurement of upward, downward and net solid fluxes was carried out in a cold model circulating fluidized bed (CFB) unit. The result shows that the profile of the net solid flux is in good agreement with the previous experimental data measured with a suction probe. The comparison between the average solid flux determined with the optical measuring system and the external solid flux was made, and the maximum deviationturned out to be 22%, with the average error being about 6.9%. These confirm that the optical fiber system can be successfully used to measure the upward, downward and net solid fluxes simultaneously by correctly processing the sampling signals obtained from the optical measuring system.

Quality of life in head and neck cancer survivors： A concept analysis

Objective： To identify and clarify the existing definitions of quality of life in head and neck cancer survivors. Thisconcept analysis will inform healthcare professionals of promoting nursing care for head and neck cancer survivors andeventually improve their quality of life. Method： Concept analysis based on Walker and Avant’s framework. Results：Quality of life is a subjective and personally derived cognitive evaluation of global well-being by perceiving a feeling ofoverall life satisfaction in his/her own value, happiness, and the independence to manage daily activities and lifeexperience. Three defining attributes for quality of life were identified： a feeling of overall life satisfaction in his/hervalue, global personal well-being, and independence. An improvement of quality of life means an improvement ofclinical outcome. However, the variety of instruments for measuring life quality makes it difficult for healthcareprofessionals to select a standard one for head and neck cancer survivors. Conclusion： By proposing a comprehensivedefinition of the concept, this analysis contributes to the advancement of knowledge about quality of life in the context ofhead and neck cancer survivorship. Through a sound understanding of the phenomenon, healthcare professions willrecognize or measure head and neck cancer survivors’ life conditions in a more accurate way and to implementintervention where necessary, eventually, improve patients’ life quality in survivorship.
