Authors: Li Tao ,   Qingdao Vocational and Technical College of Hotel Management Qingdao, Shandong 266100, China
Published: July 2019

The enrollment work of higher vocational colleges is an important part of a school’s strategic decision-making. Developing a reasonable enrollment plan is highly important for a school’s development. Previous enrollment information contains extensive valuable information, which should be used by adopting effective methods of data processing. This study used an improved Apriori algorithm to mine the association rules of enrollment information to obtain the factors that affect enrollment. A higher vocational college in Qingdao was taken as the object of study. Three attributes were selected for association rule mining: college entrance exam results, applied majors, and student background. It was found that student registration rates were significantly different under different rules. The data mining results can provide policy support for future enrollment plans.

Published: July 2019

Real-time performance assessment is one of the main methods to guarantee the steady operation of production during the combustion process of a coke oven. In this study, a real-time assessment method is proposed for this combustion process based on the analytic hierarchy process (AHP) and intuitionistic multiplicative preference relation. Relevant scholars, senior engineers, and elite workers participated in this project to build the AHP model with three aspects (i.e. safety, stability, and economic benefit) and perform pairwise comparisons of criteria and sub-criteria through group decisions. To support real-time, the pairwise comparisons of alternatives were realized by an automated method using measurement values. This comprehensive assessment method demonstrates ability to provide real-time performance evaluation for the combustion process. An experiment was conducted to evaluate the effectiveness and viability of the proposed method.
Simulations of In-Situ Upgrading Process: Interpretation of Laboratory Experiments and Study of Field-Scale Test
Authors: Perez–Perez A.. , Mujica Chacín M.. , Bogdanov I.. , Brisset A.. , Garnier O..
Published: July 2019

In–situ upgrading (IU) is a promising method of improved viscous– and heavy–oil recovery. The IU process implies a reservoir heating up and exposure to a temperature higher than 300°C for a time period long enough to promote a series of chemical reactions. The pyrolysis reactions produce lighter oleic and gaseous components, while a solid residue remains underground. In this work, we developed a numerical model of IU using laboratory experience (kinetics measurements and core experiments) and validated the results by applying our model to an IU field–scale test published in the literature. Finally, we studied different operational conditions in a search for energy–efficient configurations.

In this work, two types of IU experimental data are used from two vertical–tube experiments with Canadian bitumen cores (0.15 and 0.69 m). A general IU numerical model for the different experimental setups has been developed and compared with experimental data, using a commercial reservoir–simulator framework. This model is capable of representing the phase distribution of pseudocomponents, the thermal decomposition reactions of bitumen fractions, and the generation of gases and residue (solid) under thermal cracking conditions.

Simulation results for the cores exposed to a temperature of 380°C and production pressure of 15 bar have shown that oil production (per pseudocomponent) and oil–sample quality were well–predicted by the model. Some differences in gas production and total solid residue were observed with respect to laboratory measurements. Computer–assisted history matching was performed using an uncertainty–analysis tool with the most–important model parameters. To better understand IU field–scale test results, the Shell Viking pilot (Peace River) was modeled and analyzed with the proposed IU model. The appropriate gridblock size was determined and the calculation time was reduced using the adaptive mesh–refinement (AMR) technique. The quality of products, the recovery efficiency, and the energy expenses obtained with our model were in good agreement with the field test results. In addition, the conversion results (upgraded oil, gas, and solid residue) from the experiments were compared with those obtained in the field test. Additional analysis was performed to identify energy–efficient configurations and to understand the role of some key variables (e.g., heating period and rate and the production pressure) in the global IU upgrading performance. We discuss these results, which illustrate and quantify the interplay between energy efficiency and productivity indicators.

Authors: Hassan Hasneezah , Manaf Rosliza Abdul , S Salmiah Md , Appannah Geeta , Rosli Rozita
Published: July 2019

Background

Anaemia in pregnancy is a problem threatening public health throughout the world especially in the developing countries. Current anaemia prevention programme in Malaysia includes oral iron supplementation and health education. However, the effect of the existing intervention in ensuring compliance to the subscribed regimen and the impact of nutrition education in enhancing dietary modification during pregnancy were minimal. This study aims to develop, implement and evaluate the effects of a theory-based health educational intervention using Health Belief Model (HBM) on haemoglobin level among anaemic pregnant women.

Methods

This is a quasi-experimental research with pre-post test design with control group involving 81 participants per group from two health clinics in Sepang, Malaysia. The primary outcome was haemoglobin level. Secondary outcome include knowledge on anaemia, HBM constructs, dietary iron intake and compliance towards iron supplementation. Both groups received routine antenatal care. Additionally, the intervention group received a theory-based health education intervention programme.

Results

The response rate in the intervention and control group were 83.9% and 82.7% respectively. Generalized estimating equations analysis showed that the intervention was effective in improving the mean haemoglobin level (β=0.75, 95%CI=0.52, 0.99, P<0.001), the knowledge score (β=1.42, 95%CI=0.36, 2.49, P=0.009), perceived severity score (β=2.2, 95%CI= 1.02, 3.39, P<0.001) and increased proportion of high compliance level (AOR=4.59, 95%CI=1.58, 13.35, P=0.005).

Conclusion

Health education intervention based on the HBM is proven to be effective in improving the mean haemoglobin level, knowledge score, perceived severity score and compliance level of participants. The study results emphasized on the effectiveness of such an approach, therefore it is recommended that future educational interventions which aim at increasing preventive healthy behaviours in pregnant women could benefit from applying this model in primary health care settings.

Published: July 2019

Pediatricians face a problem of functional constipation in children and adolescents in one-third of cases of observation. Functional disorders of the gastrointestinal tract are based on disregulatory processes of the cortical-vegetative-endocrine complex. Magnesium deficiency is one of the factors influencing the formation of functional constipation in children, and an important link in the pathogenesis of the disease. Correction of magnesium level by means of magnesium-containing mineral water is one of the safe, effective and complex factors influencing a number of pathogenetic mechanisms of formation of functional constipation in children and teenagers.
Nutrition features of young children with oncological diseases in the process of antitumor treatment
Authors: Vashura A. Yu. , Alymova Ju. A.
Published: July 2019

Carrying out antitumor treatment of children with oncological diseases is often accompanied by many complications, one of the most significant eating disorders. These disorders can aggravate the existing problems, complicate the patient’s treatment and often dictate the need for special nutritional support. First of all, it is based on the limitations associated with the requirements for low microbial density of food (due to sharply reduced immunity), gastrointestinal disorders of varying severity and prevalence, peculiarities of taste and appetite of the child (which are almost always violated in the process of antitumor therapy), as well as psychological problems. In children of early age, this situation is very significant, since complications (especially gastrointestinal complications) can last for a long time, which may limit the development of the child, even if the basic treatment is successfully completed, or even prevent him or her from developing at all. Therefore, such patients need special nutritional support: enteral and often parenteral nutrition, as well as a special approach to diet, which is often based on industrial baby food products.

Published: July 2019

Infant colic is a common cause of parental anxiety and, as a result, help-seeking behaviour. However, the relationship between breastfeeding and colic is currently not fully understood. The article presents data from various studies of the relationship between breastfeeding and colic. On the one hand, the severity of infant colic may lead to the early cessation of exclusive breastfeeding due to the mother’s fear that the baby’s crying is the result of the ineffectiveness of breastfeeding and the unreasonable transition to supplemental feeding. On the other hand, many authors have identified the protective effect of breastfeeding in relation to infant colic a less pronounced degree of infant colic is reported in the group of children, who are breastfed as compared to the children, who are formula-fed. Therefore, the task of the paediatrician is to provide competent counselling for the anxious parents of an infant with colic using evidence-based medicine (EBM) databases, which will help preserve the mother’s breastfeeding. In most cases, due to competent counselling of the parents, the severity of infant colic may be reduced by improving the quality of breastfeeding (ensuring proper breast grabbing to reduce aerophagy, increasing the proportion of consumption of the so-called «back» milk), reducing anxiety of the parents and increasing the perception of breastfeeding self-efficacy levels by mothers. This may increase the duration of breastfeeding of the infants with infant colic.

Published: July 2019

Background:

Obesity is a global epidemic which is associated with several cardiometabolic
comorbidities and is characterized by chronic, low grade systemic inflammation. Numerous biomarkers
have been implicated in the pathophysiology of the disease, including transcription factors and
coregulators. Steroid Receptor Coactivator (SRC)-family represent the master regulators of metabolic
pathways and their dysregulation is strongly associated with numerous metabolic disorders.

Methods:

50 morbidly obese patients participated in the present study. Biopsies were collected from
visceral adipose tissue, subcutaneous adipose tissue, skeletal muscle, extra-myocellular adipose tissue
and liver. We evaluated the differential protein expression of NFATc1, SRC-2/TIF-2, SRC-3/AIB-1
and inflammatory biomarkers CD68 and CD3 by immunohistochemistry. The current study was designed
to determine any correlations between the transcription factor NFATc1 and the SRC coregulators,
as well as any associations with the inflammatory biomarkers.

Results:

We identified SRC-3 as a hepatic NFATc1 coactivator and we demonstrated its possible role
in energy homeostasis and lipid metabolism. Moreover, we revealed a complex and extensive intraand
inter-tissue network among the three main investigated proteins and the inflammatory biomarkers,
suggesting their potential participation in the obesity-induced inflammatory cascade.

Conclusions:

Steroid receptor coactivators are critical regulators of human metabolism with pleiotropic
and tissue-specific actions. We believe that our study will contribute to the better understanding of the
complex multi-tissue interactions that are disrupted in obesity and can therefore lead to numerous cardiometabolic
diseases. Further on, our present findings suggest that SRC-3/AIB-1 could constitute
possible future drug targets.

AbstractTransparent ZnO–MgO–Ag_2O coatings are formed on glasses by the polymer–salt method, and the optical properties of these coatings are studied. The optical properties of the films are studied by optical spectroscopy and photoluminescence. The structure of the oxide coatings is studied by X-ray diffraction analysis and scanning electron microscopy. It is found that an increase in the silver concentration in the coatings leads to a decrease in the band gap width of the material. It is shown that the films are characterized by a high transparency in the visible spectral region and can generate singlet oxygen under action of UV radiation (370 nm) and blue light (405 nm).
A Reinforcement Learning–Based Method for Management of Type 1 Diabetes: Exploratory Study
Authors: Oroojeni Mohammad Javad Mahsa , Agboola Stephen Olusegun , Jethwani Kamal , Zeid Abe , Kamarthi Sagar
Published: July 2019

Background

Type 1 diabetes mellitus (T1DM) is characterized by chronic insulin deficiency and consequent hyperglycemia. Patients with T1DM require long-term exogenous insulin therapy to regulate blood glucose levels and prevent the long-term complications of the disease. Currently, there are no effective algorithms that consider the unique characteristics of T1DM patients to automatically recommend personalized insulin dosage levels.

Objective

The objective of this study was to develop and validate a general reinforcement learning (RL) framework for the personalized treatment of T1DM using clinical data.

Methods

This research presents a model-free data-driven RL algorithm, namely Q-learning, that recommends insulin doses to regulate the blood glucose level of a T1DM patient, considering his or her state defined by glycated hemoglobin (HbA1c) levels, body mass index, engagement in physical activity, and alcohol usage. In this approach, the RL agent identifies the different states of the patient by exploring the patient’s responses when he or she is subjected to varying insulin doses. On the basis of the result of a treatment action at time step t, the RL agent receives a numeric reward, positive or negative. The reward is calculated as a function of the difference between the actual blood glucose level achieved in response to the insulin dose and the targeted HbA1c level. The RL agent was trained on 10 years of clinical data of patients treated at the Mass General Hospital.

Results

A total of 87 patients were included in the training set. The mean age of these patients was 53 years, 59% (51/87) were male, 86% (75/87) were white, and 47% (41/87) were married. The performance of the RL agent was evaluated on 60 test cases. RL agent–recommended insulin dosage interval includes the actual dose prescribed by the physician in 53 out of 60 cases (53/60, 88%).

Conclusions

This exploratory study demonstrates that an RL algorithm can be used to recommend personalized insulin doses to achieve adequate glycemic control in patients with T1DM. However, further investigation in a larger sample of patients is needed to confirm these findings.
Effectiveness of the Volunteer Family Connect Program in Reducing Isolation of Vulnerable Families and Supporting Their Parenting: Randomized Controlled Trial With Intention-To-Treat Analysis of Primary Outcome Variables
Authors: Grace Rebekah , Baird Kelly , Elcombe Emma , Webster Vana , Barnes Jacqueline , Kemp Lynn
Published: July 2019

Background

Volunteer home visiting is a widely adopted community-based approach to support families by linking isolated or vulnerable families with community volunteers who visit their homes weekly over approximately 12 months. This study seeks to robustly evaluate the effectiveness of this model of support for families with young children.

Objective

This paper reports the intention-to-treat analysis of primary and secondary outcomes for a pragmatic randomized controlled trial (RCT) of the Volunteer Family Connect intervention, a volunteer home-visiting program designed to support families with young children who experience social isolation or a lack of parenting confidence and skills.

Methods

The RCT was conducted across seven sites in Australia. Overall, 341 families were recruited: 169 intervention (services as usual+volunteer home visits) and 172 control (services as usual) families. Intervention families received the program for 3-12 months. Participants were invited to complete six data collection points over a 15-month period. Primary outcomes were community connectedness and parenting competence. Secondary outcomes included parent physical and mental health, general parent wellbeing, parent empowerment, the sustainability of family routines, and the parent-child relationship. According to the protocol, the program would be judged to be effective if at least one of the primary outcomes was significantly positive and the other was neutral (ie, intervention families did not demonstrate positive or negative outcomes compared to the control group).

Results

The intervention group demonstrated significant improvement in the primary outcome variable parenting sense of competence as compared to the control group. Overall, there was no significant difference between the intervention and control groups with regard to the primary outcome variable community connectedness, other than on the “Guidance” subscale of the Social Provisions Scale. Because there were statistically significant findings for the total score of one primary outcome variable “parenting sense of competence” and largely neutral findings for the primary outcome variable “community connectedness,” the program met the previously defined criteria for program effectiveness. In relation to secondary outcomes, intervention families reported significantly higher wellbeing and were significantly more likely to feel that life was improving.

Conclusions

The Volunteer Family Connect intervention was considered an effective intervention, with a role to play on the landscape of services available to support vulnerable families with young children.

Developing a Standardization Algorithm for Categorical Laboratory Tests for Clinical Big Data Research: Retrospective Study
Authors: Kim Mina , Shin Soo-Yong , Kang Mira , Yi Byoung-Kee , Chang Dong Kyung
Published: July 2019

Background

Data standardization is essential in electronic health records (EHRs) for both clinical practice and retrospective research. However, it is still not easy to standardize EHR data because of nonidentical duplicates, typographical errors, or inconsistencies. To overcome this drawback, standardization efforts have been undertaken for collecting data in a standardized format as well as for curating the stored data in EHRs. To perform clinical big data research, the stored data in EHR should be standardized, starting from laboratory results, given their importance. However, most of the previous efforts have been based on labor-intensive manual methods.

Objective

We aimed to develop an automatic standardization method for eliminating the noises of categorical laboratory data, grouping, and mapping of cleaned data using standard terminology.

Methods

We developed a method called standardization algorithm for laboratory test–categorical result (SALT-C) that can process categorical laboratory data, such as pos +, 250 4+ (urinalysis results), and reddish (urinalysis color results). SALT-C consists of five steps. First, it applies data cleaning rules to categorical laboratory data. Second, it categorizes the cleaned data into 5 predefined groups (urine color, urine dipstick, blood type, presence-finding, and pathogenesis tests). Third, all data in each group are vectorized. Fourth, similarity is calculated between the vectors of data and those of each value in the predefined value sets. Finally, the value closest to the data is assigned.

Results

The performance of SALT-C was validated using 59,213,696 data points (167,938 unique values) generated over 23 years from a tertiary hospital. Apart from the data whose original meaning could not be interpreted correctly (eg, ** and _^), SALT-C mapped unique raw data to the correct reference value for each group with accuracy of 97.6% (123/126; urine color tests), 97.5% (198/203; (urine dipstick tests), 95% (53/56; blood type tests), 99.68% (162,291/162,805; presence-finding tests), and 99.61% (4643/4661; pathogenesis tests).

Conclusions

The proposed SALT-C successfully standardized the categorical laboratory test results with high reliability. SALT-C can be beneficial for clinical big data research by reducing laborious manual standardization efforts.
MATHEMATICAL MODELING OF NON-STATIONARY ELASTIC WAVES STRESSES UNDER A CONCENTRATED VERTICAL EXPOSURE IN THE FORM OF DELTA FUNCTIONS ON THE SURFACE OF THE HALF-PLANE (LAMB PROBLEM)
Authors: Musayev Vyacheslav
Published: July 2019

The problem of numerical simulation of longitudinal, transverse and surface waves on the free surface of an elastic half-plane is considered. The change of the elastic contour stress on the free surface of the half­plane is given. To solve the two-dimensional unsteady dynamic problem of the mathematical theory of elasticity with initial and boundary conditions, we use the finite element method in displacements. Using the finite element method in displacements, a linear problem with initial and boundary conditions resulted in a linear Cauchy prob­lem. Some information on the numerical simulation of elastic stress waves in an elastic half-plane under concen­trated wave action in the form of a Delta function is given. The amplitude of the surface Rayleigh waves is sig­nificantly greater than the amplitudes of longitudinal, transverse and other waves with concentrated vertical ac­tion in the form of a triangular pulse on the surface of the elastic half-plane. After the surface Rayleigh waves there is a dynamic process in the form of standing waves.

The paper presents the methodic for analytical determining of stress-strain state of a beam partially supported on elastic foundation at sudden damage of foundation structure (partial failure). Bending equation for a beam is written using dimensional parameter and solved with the initial parameters method. Such approach al­lows to obtain dimensional analytical solution to static and dynamic problems for universal boundary conditions of a beam since it always leads to equations’ system of second order. Using numerical analysis for various values of generalized stiffness parameter of a system “beam - foundation”, we established affecting of the length of failure foundation part to stress-strain state of the beam for two supporting variants: partial supporting and sup­porting by two ends with foundation failure in the middle part of the beam.
NON-CONSERVATIVENESS OF FORMULAS AS AN OBSTACLE TO THE MOTION SIMULATION
Authors: Zylev Vladimir , Steyn Alexey , Grigoryev Nikita
Published: July 2019

The paper considers the specifics of connection setting between deformations and stresses as applied to the problem of large non-linear oscillations, when deformations are considered arbitrarily large. It is noted that the introduction of some arbitrary physical relations in the computational model can lead to the establishment of a non­conservative system. It is shown, for example, that distribution of the ordinary Hooke’s law formulas to the area of large deformations leads to the establishment of material with the non-conservative properties. The examples are given for the numerical solution of problems with the nonlinear oscillations, where an increase in the oscillation am­plitudes or occurrence of unauthorized internal friction is shown. The simplest version of the material properties free from the indicated deficiencies is given. One of the paper conclusions is that when specifying the elastic properties of the material, it is necessary to ensure that the resulting system is conservative.

Effects of arbuscular mycorrhiza fungi, organic fertilizer and different moisture regimes on soil properties and yield of Amaranthus cruentus
Authors: Adekanmbi Adebisi , Adewole Moses
Published: July 2019

A pot experiment was conducted to assess the influence of two arbuscular
mycorrhiza (AM) fungi and organic fertilizer (OF) on the growth and yield of
Amaranthus cruentus under varying soil moisture regimes. This was done with
a view to providing information on the crop adaptation to drought conditions
and to also sustaining soil nutrient balance for increased crop yields. The
experiment consisted of 36 treatments (Glomus clarum, Glomus deserticola and
no AM), organic fertilizer made from market wastes at different rates (0, 5
and 10 t ha- 1) and varied water regimes (25, 50, 75 and 100% field capacity
[FC]). Each of the treatments was replicated thrice. The treatment
combination, 10 t ha-1 OF and G. clarum produced the highest fresh
vegetative yield of 48.82 t ha-1 which was not significantly (p > 0.05)
different from only 45.78 t ha-1 fresh yield obtained with 5 t ha-1 OF and
G. clarum when water levels were compared. The repeated experiment with only
water addition gave lower and comparable yields of A. cruentus. We concluded
that the addition of G. clarum in combination with 5 t ha-1 of organic
fertilizer to soil optimally improved the growth and yield of A. cruentus in
water stress conditions.

Published: July 2019

Nigeria is among countries of the world confronted with the food insecurity
problem. The agricultural production systems that produce food for the
teeming population are not sustainable. Consequently, the use of Sustainable
Land Management (SLM) technologies becomes a viable option. This study
assessed the effect of SLM technologies on farming households? food security
in Kwara State, Nigeria. A random sampling technique was used to pick 200
farming households for this study. The analytical tools included descriptive
statistics, Shriar index, Likert scale, food security index and logistic
regression analysis. The results indicated that the average age of the
respondents was 51.8 years. The food security index showed that the
proportions of food secure and insecure households were 35% and 65%
respectively. The binary logistic regression revealed that SLM technologies
were one of the critical determinants of food security. An increase in the
usage of SLM technologies by 0.106% raised food security by 1%. Other
important factors that were estimated included farm income, family size,
gender and age of the household head. To reduce the effects of food
insecurity, the effective coping strategies adopted by the respondents were
reduction in quantity and quality of food consumed, engaging in off-farm
jobs to increase household income and using of money proposed for other
purposes to buy foods. Governments at all levels should encourage the
adoption and use of SLM technologies through both print and electronic
media. Policies and strategies towards reducing the household size should be
vigorously pursued to reduce food insecurity.

Past research indicates a large percent of Indonesian domestic workers being exposed to exploits, verbal and sexual abuse that further exposes them to various problems such as psychological, social, cognitive, behavioural, and physical challenges. Few subjects have thus far have been taken out on the prevalence of and associate factors with depression among Indonesian domestic workers in Malaysia. The objective is to know the prevalence of and the associated elements of depression among Indonesian domestic workers in Malaysia. This study engaged mix method. Quantitative information was accepted from 380 respondents by using Beck depression inventory (BDI-II), while qualitative data was collected from selected 32 respondents who have moderate depression (BDI-II) through interview. The questionnaire of total randomly 380 subjects were retrieved and 228 where participants who have depression symptom according to BDI-II. Three from five Indonesian domestic workers in Malaysia are having a depression symptom (60 percent). This study found that occupation, financial hardship, social support, and level education are the associate factors of depression among Indonesian domestic workers in Malaysia. Meanwhile, most of domestic workers who live with their employer have a moderate to severe depression. The awareness created through this study will enable proper government-to-government policy on domestic migrant workers matters, hence reducing the low rate and policy level intervention. It will as well contribute to the consistency of knowledge on depression of Indonesian domestic workers in a foreign country, especially the advocates and the social workers employed by the Indonesia embassies in all countries.

Rumänische Realität surrealistisch verkörpert: Joachim Wittstocks Erzählung Hades, (m)eine postmoderne Lesart
Authors: Puchianu Carmen Elisabeth
Published: July 2019

Our analysis of Joachim Wittstock’s narrative entitled Hades and published thirteen years after the fall of the communist regime in Romania aims at pointing out the intimate connection between socio-political reality and personal experience reflected by the creative process of turning reality into fiction by writing. We consider the chosen narrative both as a political and literary statement, reflecting much of the way of life in Romania during the late 1980s. The narrative may be considered as some kind of withheld fiction and a pertinent comment of the author as to the role of fiction in a totalitarian regime.

Die Schwarze Kirche als Topos der kollektiven Identitätskonstruktion in der deutschen, rumänischen und ungarischen Lyrik der Zwischenkriegszeit
Authors: Jakabházi Réka
Published: July 2019

The Black Church, the largest sacral building in Transylvania, has been given a central role in the local identity narratives. As a historical place of remembrance, it mediates and mobilizes elements of historical knowledge, and at the same time constructs a myth.The article examines how the Black Church in Brasov, one of the most important symbols of the Transylvanian Saxons, is poetically constructed as a place of cultural memory in the German, Romanian and Hungarian poems of the interwar period, how the concrete place is reinterpreted as a space for creating identity, while the ethnic dimension should not be ignored. It examines the question of what symbolic value it has for the German, Romanian and Hungarian populations and how this can be seen from the lyrical texts of the time.
Auch das Beständigste war nicht mehr von Dauer!1 Die Darstellung des Eigenen und des Gegenübers in Andreas Birkners Roma Die Tatarenpredigt
Authors: Sass Maria
Published: July 2019

The present study focuses on imagology. Starting from the theoretical aspects of the concepts self-image and hetero-image, the analysis ponders upon the imagological constructs of two ethnical groups in the novel of the Romanian German-language author Andreas Birkner. In this analysis, the self image identifies with the one of the Transylvanian, and the image of the other is that of the Roma. The analysis of Birkner's novel leads to the conclusion that there have been certain mental images deeply rooted in historical reality and which can be, partly, explained by means of collective memory parameters. Stereotypes and prejudices should be considered in this context.
Clinical Ankle Involvement and Ultrasound Synovial Hypertrophy are Significant Predictors of DAS28-Defined Rheumatoid Arthritis Disease Activity

Published: July 2019

Objective. The study aimed to investigate the relationship between ankle involvement and disease activity in rheumatoid arthritis (RA), from clinical and ultrasound perspectives.

Methods. RA patients were recruited in 2018 in the random order of presentation from the out-patient clinic. On the same day of inclusion, all patients underwent clinical examination, laboratory tests (inflammatory markers), ankle ultrasound and patient-reported outcomes.

Results. The study included 183 patients with established RA, mostly women (86.3%), with mean age of 57.3 years. Clinical examination revealed 101 (55.2%) patients with at least one tender ankle and 56 (30.6%) patients with at least one swollen ankle. Regression analysis revealed that both clinically tender and swollen ankles were 2.8 and respectively 3.4 times more likely to reveal ultrasound ankle joint synovial hypertrophy (SH). The presence of ankle SH was associated with higher disease activity: for example, compared to patients without ankle SH, patients with ultrasound-detected SH in any ankle joint had significantly higher median DAS28CRP (4.60 compared to 2.73, p<0.001). Power Doppler (PD) activity of ankle SH produced similar results: PD signal presence (p<0.001) and PD grade (p = 0.009) were associated with higher median DAS28CRP. Ankle joint involvement had an independent effect on DAS28CRP-defined disease activity: for example, the absence of ankle SH independently and significantly decreased DAS28CRP with 0.985 points (p<0.001).

Conclusion. Clinical ankle involvement and ultrasound-detected ankle SH have a directly proportional relationship with disease activity in RA.
Ecological analysis of heavy metal and radioactivity potential of Holocene sediments in Iznik Lake
Authors: Yumun Zeki U. , Kam Erol
Published: July 2019

In this study, the heavy metal and radioactive properties of Iznik Lake were investigated. Concentration values of the first (Ag, Bi, Mo, Sn, Se, Zn, As, B, Cd, Co, Cr, Cu, Ni, Pb, Pt and Sb) and second (Na, Mg, K, Ca, P, S, Fe, Al and Mn) group of elements in borehole 1 (BH-1) drilling did not show much variation from the top to the bottom of the drilling. Concentration values of the first group of elements in borehole 2 (BH-2) drill samples decreased at higher levels of drilling. In addition, natural and anthropogenic radionuclides were measured by gamma spectrometry, and the results of environmental natural radioactivity of Iznik Lake and its surroundings were determined. In the measurement results, Ra-226 was found to be below the world average value at all locations. It is assumed that the determination of K-40 values above the average values was due to agricultural activities carried out intensively in the study area. Th-232 values were found to be below the world average value in drilling samples; Cs-137 values were below the background level in all samples. According to these results, the study area does not contain any unnatural radioactivity.
Estágios, formação profissional e trabalho: contratos e retratos
Authors: Zenha Martins João
Published: July 2019

The text concerns the history and importance of the professional training in the socio-political context which enhances the concept of employability. Nevertheless, is possible to see that the global system of the professional learning is fragmented which allows to have space for a low rigorous use of it. Due to the implicit low costs and the susceptibility of satisfaction of the no temporary business needs, the different types of internships’ contracts tend to work as an alternative to the labour contractual system.
A marca olfativa no novo código da propriedade industrial de Moçambique
Authors: Muressama Viagem Salomão António
Published: July 2019

The most recent Industrial Property Code of Mozambique (CPIM), approved by Decree 41/2015 of 31 December, brought, among other innovations in the field of trademarks, the consecration of the olfactory brand, one of the "new complex in terms of distinctive capacity and graphic representation, the latter being a very controversial aspect in the field of registration assumptions of the new brands. Although the problem of graphic representation has been circumvented by the European Union trademark law in accordance with its new Trademark Directive ( (EU) 15/2436 of Parliament and Council of 16 December 2015) which has removed it from the range of requirements of the trademark concept; many legal systems such as Mozambican law still maintain it. In fact, the reason for this theme is: to study the olfactory mark and its tutelage in Mozambique. The graphic representation of the new brands, and especially of the olfactory mark, is generally problematic. It seems that the new Industrial Property Code of Mozambique has been daring to consecrate this type of mark following the brand name (of the same species was provided for in the previous Code without however having known a single application for registration so far among other possible reasons, due to the difficulty of graphical representation. Will not end the olfactory mark by following the same path and be another type of trademark foreseen in CPIM without any registration? Nevertheless, with the consecration of the olfactory mark, the attention of the Mozambican legislator must be recognized and welcomed by the dynamics of the types of brands that currently have as a whole the new brands as an undeniable reality.
