Perfil de médicos ginecologistas/obstetras de Londrina com relação à saúde oral da gestante

This research aims at establishing a profile of the gynecologists/obstetricians from Londrina regarding the pregnant women s dental health, in order to obtain support * Autora: Aluna do 5 o ano de Graduação em Odontologia da Universidade Estadual de Londrina. ** Orientador: Mestre em Odontopediatria, Prof Adjunto de Odontopediatria da Universidade Estadual de Londrina/Centro de Ciências da Saúderua Pernambuco, 540 Fone (043) 321-2002 CEP 86020-070 Londrina Paraná. 34 Semina, v. 18, ed. especial, p. 34-42, fev. 1997 to build up an integrated plan of action based on the concept of health promotion as well as on the context of general health Attempts were made to define some personal data and professional background and to identify procedures of dental interest routine applied to the pregnant woman (oral exam, forwardness to the dental surgeon, precautions for the cavity prevention and periodontal disease), as well as to knowledge about dental issues (etiology of the periodontal disease, diet and fluoride supplement). The data collection was done by means of interviews/questionnaires. The conclusion drawn was that most of the physicians who were interviewed evaluate the oral cavity of their pregnant patients, but only half of them adopt this procedure as a routine; that the dietary control is widely used aiming at maintaining the pregnant woman s weight; that prescription of systematic fluoride is usual habit and the most appropriate means for achieving that is the use of polyvitamins; and most physicians state that they never received any kind of orientation about dental health during their undergraduate or graduate program.
An investigation into the inter-rater reliability of ultrasound imaging of abdominal muscles in adults

Background:Ultrasound imaging is a non-invasive tool that could be useful in observation of bodily structures, diagnostic purposes, bio-feedback and as an outcome measure. As core stability has become a focal point in rehabilitation, the ability to observe the muscles involved could prove to be clinically useful.Aim:This study was therefore conducted to determine the inter-rater reliability of the ultrasound imaging machine.Methods:Rectus Abdominus (RA), External Obliquus (EO), Internal Obliquus (IO) and Transversus Abdominus (TrA) were imaged in both a relaxed and a contracted condition. Fifty one participants of thirty years and older were recruited from visitors to a tertiary hospital. Two investigators independently measured the thickness of the abdominal muscles.Results:Generally there was a strong relationship when measuring RA, IO and EO, although strong contractions did not meet the criteria set for reliability. RA relaxed had the strongest correlation between raters (r=0.89, p<0.01) while IO oblique crunch (OC) showed the weakest correlation (r=0.58, p<0.01. A significant difference was found in thickness from the relaxed state to measuring EO hollowing-in-manoeuvre (HI) (p=0.02), Oblique Crunch (p<0.01) and RA chin-to-chest (p<0.01). Generally, males showed a significantly larger muscle thickness compared to females and a high Body Mass Index (BMI) was associated with unclear images (p<0.01). Conclusion:The use of the ultrasound imaging machine results in reliable measurement regarding the more superficial muscles in a state of relaxed or moderate activity, even when used by relatively inexperienced therapists. It is recommended that US can be used as a reliable outcome measure of most abdominal muscle activity.
IMPROVEMENT OF SOME NUTRITIONAL VALUES OF TOMATOES VIA SALINITY

The antioxidant activity status is important to determine the nutritional value of fruits and vegetables. Increased antioxidant levels not only have high benefits in preventing widespread human diseases, including cancer and cardiovascular pathogens but also it enhances shelf life as well. This study was carried out to test the effects of 100 mM NaCl on some antioxidants (vitamins C and E) and some monosaccharides (glucose and fructose) of TYLCV virus-free tomato plants (Solanum lycopersicon) cultivar Castle Rock. The plants were treated at 30 days old with 100 mM NaCl for the next 45 days. At 75 days old, mature leaves were harvested and tested for TYLCV infection, as this virus affects the amount of antioxidants in tomato plants. Plants were kept in cages to avoid infection with TYLCV. The plants gave negative results, confirming that they are virus-free. Levels of vitamin C and vitamin E were determined by a reverse-phase HPLC technique while levels of glucose and fructose were determined using UPLC-MS in 75 days treated tomato leaves. Plants showed an increase in vitamin C, α-tochopherol, glucose and a slight increase in fructose contents versus the control plants. These results are of great importance from the nutritional and health points of view where salt stress improved the plant quality by increasing the concentrations of important antioxidants (vitamin C and vitamin E). In conclusion, the use of controlled salinity level can be an effective method to produce tomatoes of good nutritional quality and with higher market price.
Deformation Forecasting of Surrounding Rock Mass Based on Correlation between Frequency and Fracture Scale of Microseismicity

The macroscopic deformation and failure of engineering rock mass may occur as a result of evolution and breakdown of its internal microfracture. Therefore, the macroscopic state of rock mass can be obtained from fracture scale of microfracture in real time. To assess instability and predict macroscopic deformation and failure of engineering rock mass, a time-frequency analysis technique based on S transform was proposed to investigate microseismic waveform and reveal the correlation between macroscopic deformation failure and microseismic frequency characteristics of engineering rock mass in combination with fracture scale. To minimize the influence of external factors on parameters calculated, a significant amount of microseismic data from three large-scale hydropower projects in southwestern China was collected as the statistical sample. The analysis of correlation between fracture scale and frequency characteristics of microseismic events was carried out based on the statistical sample. Combining with microseismic data and multipoint extensometers in the underground powerhouse of the Houziyan hydropower station, engineering verification was conducted. The result shows that the high-frequency components decrease and microseismic signals display low-frequency characteristic as the fracture scale increases; the microseismic high-frequency components decreased at first and then increased during the deformation process of surrounding rock mass, and the frequency of microseismic events shifts from high band to a lower one before deformation.
Influence of housing system on the growth and histological structure of duck muscles

This study was aimed at determining the effect of housing systems on the growth, feed conversion ratio (FCR), meatiness and size of muscle fibres of Pekin (P44) and Muscovy (MR71) ducks. Each genetic group included 360 birds (180 males and 180 females). The ducks were divided into four experimental groups according to their sex and housing system: intensive system (IS) and outdoor system (OS). A significant effect of housing system on the final body weight and FCR value was noted only in P44 birds of both sexes, with OS birds having higher body weights than the IS birds. As a result, the OS MR71 drakes were characterized by a significantly higher slaughter yield, weight and content of breast muscles in the carcass. The OS MR71 ducks showed a lower slaughter yield and a higher content of leg muscles in the carcass compared to IS MR71 ducks. In contrast, the housing system had no significant effect on the meatiness of P44 ducks. A greater diameter of muscle fibres in both sexes of P44 ducks and in both sexes of MR71 ducks was observed in the OS compared to IS flocks. A greater cross section of muscle fibres was also noted in the ducks from the OS system, however with significant differences confirmed only in pectoralis superficialis and biceps femoris in MR71 drakes as well as in the biceps femoris of P44 drakes. These data show differences between duck genotypes and indicate the efficiency and potential of outdoor poultry systems.
Training autoencoders for state estimation in smart grids

Desde a sua implementacao massiva nos centros de controlo dos sistemas electricos de energia, o estimador de estado apresenta-se como uma ferramenta de capital importância uma vez que permite a obtencao de um ponto de funcionamento do sistema com elevada precisao. Com efeito, uma das etapas essenciais a definicao desse ponto de funcionamento e a determinacao da topologia, isto e, o estado aberto ou fechado dos dispositivos de corte e seccionamento que a rede em questao possui.Assim, uma miriade de metodologias foi proposta com o firme intuito de enderecar o problema da identificacao de topologia. Os primeiros passos foram dados em meados dos anos 80 sendo apresentadas abordagens baseadas em metodos puramente matematicos e na analise dos seus resultados para a deteccao de eventuais erros de topologia. Todavia, atraves da crescente popularidade e avancos nas areas da inteligencia artificial e da ciencia da computacao, foram desenvolvidos modelos baseados em redes neuronais, evidenciando resultados convincentes com pesos computacionais mais reduzidos e sendo, simultaneamente, livre dos problemas de convergencia dos metodos estritamente analiticos.Tendo isto em consideracao, nesta tese e ilustrada uma nova perspectiva da aplicacao de redes neuronais, deep learning e Teoria de Informacao (ITL) ao problema da determinacao de topologia e, em ultima instância, a estimacao de estados. Atraves da conjuncao destes conceitos, pretende-se identificar a topologia de um dado sistema electrico de energia recorrendo ao reconhecimento dos padroes das medidas analogicas providenciadas, apontando, ao mesmo tempo, metodologias alternativas ao nivel do treino e arquitectura de redes neuronais bem como de ferramentas computacionais que conduzam a uma maior eficiencia desse processo. Particularizando, serao exploradas duas filosofias diferentes com elementos de treino supervisionado e nao supervisionado e com arquitecturas tipicas de autoencoders e redes neuronais feedforward aplicadas a descoberta da topologia de um sistema IEEE RTS 24. Para alem do proposito de contrastar a eficacia de cada um dos metodos, serao igualmente demonstradas comparacoes no que concerne o peso e rapidez computacional atraves da utilizacao de CPU e GPU de modo a atestar as potencialidades desta ultima tecnica em aplicacoes concretas nos sistemas electricos de energia.
The Effect of Leadership Style on the Organizational Culture: Evidence from Turkey

The leadership-style of an organization leader plays an important role in forming and maintaining organizational culture. The main objective of this study is to determine the leadership styles of leaders in armed forces and reveal the effects of leadership styles on the typologies of the organizational culture. The study had an explanatory method and the data collection tool was a questionnaire. According to the results, while the transactional leadership style was brought to forefront from the leadership styles of leaders in armed forces, the hierarchy culture was brought to forefront from the typologies of the organizational culture. It was determined that while the transactional leadership style did not affect the clan and adhocracy culture, it positively affected the market and hierarchy culture. Furthermore, the transformational leadership style positively affected the clan and adhocracy culture, whereas it negatively affected the market and hierarchy culture. Besides, some differences were observed on cultural dimensions perceived by commanders performing a duty in provinces in eastern and western regions. Commanders performing a duty in the eastern region perceived greater adhocracy culture compared to commanders performing a duty in the western region. Commanders serving in the western region perceived greater market and hierarchy culture than commanders serving in the eastern region. As a consequence, it could be asserted that the leadership styles of leaders shape the organizational culture. Keywords: Leadership style, Organizational culture, Armed forces JEL: M14, D23
Experimental Economics: Some Methodological Notes

The aim of this work is presenting in a self-contained paper some methodological aspects as they are received in the current experimental literature. The purpose has been to make a critical review of some very influential papers dealing with methodological issues. In other words, the idea is to have a single paper where people first approaching experimental economics can find summarised (some) of the most important methodological issues. In particular, the focus is on some methodological practises still debated in experimental literature, such as attainment of control in experimental settings, subject pool, incentive mechanisms, repeated trials and learning. The hope is that increasing awareness on some sharing methodologies will improve the robustness of results in this research field.
Determinants of Corporate Performance of Listed Companies in Indonesia

This paper is basically concerned with the factors determining corporate performance of listed companies in Indonesia, especially due to the 1997 financial crisis. The main results are fairly interesting in which firm size is positively related to firm profitability, but it is not related to market capitalization. It means that firm size is matter on the fundamental value of the firms, but it should not be important variable for market value of the firms. By employing panel data of 238 listed companies in Jakarta Stock Exchange (JSX) in the period 1994 – 2004 as the sample, we also find that macro factors are more important variables inducing firm performance, rather than firm-specific factors. It could be due to the 1997 great crisis. Our results also show that ownership factor matters on firm performance by the evidence that firms with majority foreign ownership have much higher performance in both measurements namely return on asset (ROA) and market capitalization growth than domestically-owned firms. Ordinary Least Square (OLS) is employed for the estimation procedure in this paper.
Allelic diversity of the population of Phytophthora infestans in China

Introduction of resistance genes from wild Solanum species into potato cultivars is considered the most promising and environmentally safe approach to achieve late blight resistance. An R-gene stacking breeding program using cisgenesis is planning to trial its products in China. To adapt this approach to local conditions, we propose to assess the allelic diversity of known avirulent genes of P. infestans from the intended introduction regions of the GM-potatoes in China. So far, we have a large (~100 isolates) and geographically diverse collection of P. infestans. We measured diversity in the isolates based on sequences and functions of several known Avr genes. The work relied on molecular and modern computer tools to examine the dynamics of the pathogen population structure and evolutionary relationships among different genotypes. We aim to give an ecological assessment of the Chinese population of P. infestans, which would be a guideline for the release of cisgenetic plants with stacked R genes

AN INVESTIGATION ON HETEROSIS AND INBREEDING DEPRESSION IN THE SILKWORM (Bombyx mori L.)

The aim of this study was to define heterosis and inbreeding depression in the four silkworm (Bombyx mori L.) races namely C108, NB4D2, Pure Mysore and Nistari for four important characters including larval weight, cocoon weight, shell weight and shell percentage. The traits of larval weight and cocoon weight showed highly significant heterosis in F1 hybrids ranging from 11 to 23% and 14 to 27 % respectively, while inbreeding depression in the F2 progeny ranged from 0.366 - 10.814% and 2.682 - 12.312% respectively. Shell weight showed low level of heterosis in F1 hybrids (14 to 20 %), whereas the effect of inbreeding depression in F2 progeny was -4.369 to 8.467% for this character. C108 × NB4D2 hybrids proved to be a good specific combiner by making higher contribution towards heterosis both in F1 hybrids and inbreeding at F2 generation.
Influence of Conditions of Service and Principals' Leadership on Job Satisfaction of Secondary School Deputy Principals in Kenya: A Case Study of Hamisi Sub -County

Deputy Principals play a pivotal role in management of schools. The prerequisite of good job performance by a deputy principal is job satisfaction. However, when they are not satisfied they are likely to decline the position of deputy headship. From 2008 to 2012, four deputy Principals resigned, 2 were demoted and 15 refused to take up deputy headship in Hamisi Sub County, citing deputy headship position as not fulfilling. This was contrary to other neighbouring sub counties like Sabatia, Vihiga and Emuhaya which experienced only 3 cases of refusal to take up deputy headship position. The study established that the following factors influenced deputy principals job satisfaction: deputizing principals, acting as a principal in absence of the principal, disciplining students, student adherence to school rules and regulations, salaries, medical allowances, house allowance, celebration of Kenya Certificate of Secondary Education results, delegation of duties to teachers, proximity of the school from the road network and proximity of deputy principal’s office to the principal’s office. The study concluded that the terms and conditions of service and principal’s leadership factors influence job satisfaction of deputy head teachers. The study recommended that Teachers Service Commission should improve on salaries and medical allowances for teachers while the principal should provide for housing. The findings of this study are significant to the Ministry of Education, students and teachers, Teachers Service Commission, County Directors of Education, Deputy Principals and Principals in formulating policies that promote job satisfaction and add to the body of knowledge on job satisfaction.
(Very) Rapid Decision Making: framing or filtering?

This paper addresses two issues that arise from the challenge of studying the rapid decision making that characterises the domains of Naturalistic Decision Making. First, we are interested in how it is possible to make decisions in fractions of seconds. Second, we are interested in how such rapid decision making can be modelled. As a corollary to the first issue, we are also interested in exploring decision making which eschews the need to appeal to a concept of schema. Taking a cybernetic approach to decision making, we describe a model in which expertise is defined by the ability to filter salient features from the environment rather than in terms of the complexity of schema that is applied.
The Rolls on the Ellesmere Ice Shelf

Surface rolls are characteristic features of both the Ellesmere ice shelf and the floating ice islands derived from it. These surface features are described and their origin and evolution discussed. Various theories of origin are considered which involve such forces as pressure from the polar pack, movement of glaciers, temperature variations, tidal movements and wind. Of these, wind action appears the most likely to have caused the rolls, and it is suggested that their development was analogous to the formation of seif dunes in desert. "They should be regarded as fossil snow dunes that have been perpetuated by the annual drainage of melt-water. "
Purification and characterization of cell-envelope proteinase from Lactococcus casei

Using a Ca 2+ -free method, the cell-envelope proteinase (CEP) of Lactobacillus casei DI-1 isolated from duck small intestine was released from cells and purified by ammonium sulfate precipitation, and by diethylaminoethyl (DEAE)-Sephadex A-25 and Sephadex G-100 gel chromatography. The purified CEP had a monomer structure with a molecular mass of about 35 kDa. Optimal activity occurred at pH 7.0 and 37°C. The purified CEP was a metallopeptidase, which was activated by Co 2+ , Ba 2+ , Mg 2+ and Fe 3+ , and inhibited by Ca 2+ , Zn 2+ , K + , Ni 2+ , Mn 2+ , and ethylenediaminetetraacetic acid (EDTA). It was a serine proteinase which was inhibited by phenylmethylsulfonyl fluoride (PMSF). Its kinetic constant (Km) is 0.29 mM and the first 10 amino acids of the CEP’s N-terminal sequences were Asp-Asn-Asp-Phe-Glu-Ile-Phe-Glu-Ser-Ser. The hydrolysates of α-, βand κ-casein produced by CEP showed different angiotensin-I-converting enzyme (ACE) inhibitory activity; the hydrolysates of β-casein displayed the greatest ACE inhibitory activity.
Discussion on ‘Automatic and controlled processes in behavioural control: Implications for personality psychology’ by Corr

This comment critiques Corr’s (2010) characterization of the personality traits associated with the elements of Gray’s conceptual nervous system: The behavioural inhibition system (BIS), the behavioural approach system (BAS) and the fight-flight-freeze system (FFFS). Most attention is paid to the FFFS because least is known about its manifestation in personality. Additionally, I suggest that Corr’s framework for understanding automatic and controlled processing is useful for developing theories of the biological systems underlying traits that are not directly related to BIS, BAS and FFFS.

Dynamic Skill Accumulation, Comparative Advantages, Compulsory Schooling, and Earnings

We show that a calibrated dynamic skill accumulation model allowing for comparative advantages, can explain the weak (or negative) effects of schooling on productivity that have been recently reported (i) in the micro literature on compulsory schooling, ii) in the micro literature on estimating the distribution of ex-post returns to schooling, and (iii) in the macro literature on education and growth. The fraction of the population more efficient at producing skills in the market than in school is a pivotal quantity that determines the sign (and magnitude) of different parameters of interest. Our model reveals an interesting paradox; as low-skill jobs become more skill-enhancing (ceteris paribus), IV estimates of compulsory schooling become increasingly negative, and ex-post returns to schooling (inferred from a Roy model specification of the earnings equation) become negative for an increasing fraction of the population. This arises even if each possible input to skill production has a strictly positive effect. Finally, our model provides a foundation for the weak (or negative) effect education on growth measured in the empirical literature.
