Becoming an insider : The internationalization of firms in the health care sector

During the past decades, a number of countries have reformed their health care systems, allowing private actors to become health care providers. Accordingly, health care markets are rapidly emerging all over the world, constituting important opportunities for SMEs to expand their operations internationally. Since the health care sector is characterized by high complexity being highly regulated, highly professionalized and to a high extent localized entering such markets are greatly influenced by the institutional context and the SME’s relationships to political, legal, professional and business actors. The business network in which the SME is embedded is of significant importance in gaining access to new markets and to local market knowledge. The purpose of this paper is to enhance our knowledge of health care SMEs’ means to build and use network relationships in order to contribute to both the IMP research tradition as well as the internationalization process literature.
Determinants of Adoption and Use of E-Learning for Teaching Techno-Vocational Skills in Tertiary Institutions in Rivers State during COVID-19 Pandemic in Nigeria

The study investigated the determinants of adoption and use of e-learning for teaching techno-vocational skills in tertiary institutions during covid-19 pandemic in Nigeria. It sought to find out the relationships that exist between the factors related to instructors and the adoption and implementation of e-learning. Five research questions were posed and five null hypotheses formulated which guided the study. The correlation survey design was adopted for the study. The study population was 205, which comprised all academic staff in Faculties/Schools of technical and vocational education in three tertiary institutions in Rivers State. The entire population was used without sampling because it is of manageable size. Two sets of instruments were used for data collection, namely: Determinants Factors of Instructors’ Scale and Adoption of E-learning Inventory Scale. The instruments were structured on 5-point rating scale. The instruments were face validated by three experts in the Faculty of Education in Rivers State University. The instrument was pilot-tested on a representative sample of 30 respondents from faculty of engineering in Rivers State University, which are not part of the study population. The response of thirty (30) representatives were
Active Aging: Roles of Physical Activity and Immunity

We introduced the physiological responses of aging, active aging and also suggest the impact of physical exercise on body health status and elderly immunity. In this purpose, we searched the Pub Med data base for the articles (include our experimental papers) and review papers having the terms 'Aging', 'Active aging' and 'Physical activity and elderly' in the title, published from 1999 until 2018. The results were as follows: Exercise training has been extensively studied about the reduction of inflammation, oxidative stress, disease, and aging in syndrome X patients and elderly. Combined and aerobic or resistance exercise training could reduce obesity, insulin resistance, type 2 diabetes and hypertension. Exercise training has been extensively studied in cancer settings as part of prevention or treatment strategies. From this research, regular exercise has the potential to target tumor growth through regulation of inflammation and immune responses such as lactate clearance, NK cell activation (innate immunity), activation of cytotoxic immune cells, T cell activation (adaptive immunity), and immune surveillance. However, Endurance physical activity not only induces thermogenesis and diverse sports injuries but also elicits mobilization and functional enhancement of monocytes, neutrophils (which is caused by the cytokine changes such as TNF-alpha, IL-1) whereas it suppresses cell mediated immunity causing to increased susceptibility to inflammation and infections like cough and URTIs (upper respiratory track infections) in young and especially in elderly people. Therefore, Strategies to prevent physical fatigue, sports injuries include avoid overtraining, Adequate recovery and various type of rest during and after physical activity and assuring adequate nutrition supplementation such as glutamine, vitamin B, vitamin C, carbohydrate, ion or berry-contain sports beverages is helpful in physically active elderly.
Effectiveness of Tongue Cleaning Plus Chemical Mouthwash Agents into the Number of Oral Microorganisms Caused Aspiration Pneumonia in Bedridden Elderly Patients: A Crossover Study

To evaluate the effectiveness of tongue cleaning plus mouthwash on the number of microorganisms caused pneumonia in bedridden elderly patients. Twelve bedridden elderly participated in this crossover design. The participants were randomly divided into three groups of tongue cleaning methods as follows: group 1, chlorhexidine gluconate (CHX); group 2, water (W); group 3, povidone iodine (PVP-I). The number of microorganisms caused aspiration pneumonia (total anaerobic bacteria, total aerobic bacteria, Streptococci, Staphylococcus aureus, Pseudomonas aeruginosa) and Candida spp. were measured on the dorsal of tongue surface at baseline, rapidly and at 3 hours after tongue cleaning. The percentage of the number of microorganisms reduction for tongue cleaned with CHX (> 60 % for all) were higher than PVP-I and W group, and trended to continue effect for 3 hours. The percentage of reduction for tongue cleaned plus CHX was significant differences in the number of total anaerobic bacteria, total aerobic bacteria, Streptococci, Staphylococcus aureus and Pseudomonas aeruginosa after cleaning and 3 hours after cleaning compared to W group. The effectiveness of tongue cleaning plus CHX to reduce the number of bacteria was no difference the tongue cleaning plus PVP-I. For the number of Candida spp. , the CHX was significant differences in rapidly after cleaning but only the CHX group was significantly in 3 hours after cleaning compared to PVP-I and W. CHX might be recommended for clinical practice guideline of tongue cleaning in the bedridden elderly patients. Clinical article (J Int Dent Med Res 2020; 13(4): 1341-1348)
Comparative Evaluation of the Push-Out Bond Strength of Three Root Canal Sealers

In this study, the bond strength of three root canal sealers, i.e., AH Plus, GuttaFlow 2 and BioRoot RCS to the intra-radicular dentin, was evaluated by the push-out test design. Thirty extracted teeth with single roots without fractures or defects, presenting with closed apices, were randomly divided into three groups, with each group containing ten samples. The samples were decoronated, standardizing the length of the samples to 15 mm uniformly. Canal instrumentation was done using ProTaper Universal rotary files upto size #F3 and lateral compaction technique was used for obturation with 2% taper standardized gutta-percha along with each of the three different sealers. After obturation and final setting of the sealers, the specimens were sectioned and observed under the stereomicroscope to check the integrity of the obturation and were then subjected to push-out bond strength test. The results of the test revealed that the push-out bond strength of BioRoot RCS was greater compared to AH Plus and GuttaFlow2, which was statistically significant with p<0.05. Push-out bond strength in the decreasing order was as follows: BioRoot RCS > GuttaFlow2 > AH Plus. Experimental article (J Int Dent Med Res 2020; 13(4): 1304-1308)
Level of Tumor Necrosis Factor Alpha in Elderly Patients with Periodontitis and Diabetes Mellitus

Periodontal diseases, such as periodontitis, have risk factors in common with other systemic and chronic inflammatory disorders. One inflammatory mediator that plays a role in the proinflammatory process is tumor necrosis factor α (TNF-α). With age, the body's inflammatory responses change, and this is one reason why periodontitis is common among elderly patients. We compared TNF-α levels of 33 elderly patients with periodontitis who did not have diabetes with those of 18 elderly patients with both periodontitis and diabetes mellitus. Patients’ gingival crevicular fluid (GCF) was taken from sites with pocket depths of 5 to 6 mm, and their TNF-α levels were measured. Clinical data (pocket depth, bleeding index, and clinical attachment loss) and GCF samples were collected. Patients with diabetes had significantly higher Oral Health Information Suite indexes (3.1 ± 1.25) than did those without diabetes (2.17 ± 1.29; p < 0.05). Patients with diabetes had significantly higher TNF-α levels (5.04 ± 0.48) than did those without diabetes (4.67 ± 0.76; p < 0.05). Thus, the level of TNF-α is significantly higher in patients with diabetes than in those without. Clinical article (J Int Dent Med Res 2020; 13(4): 1461-1466)
PERSONALITY PROCESSES AND INDIVIDUAL DIFFERENCES Developmental Structure of Personality and Interests: A Four-Wave, 8- Year Longitudinal Study

Personality traits and vocational interests capture different aspects of human individuality that intersect in certain ways. In this longitudinal study, we examined developmental relations between the Big 5 traits and RIASEC vocational interests over 4 timepoints from late adolescence to young adulthood (age 16–24) in a sample of Icelandic youth (N 485) well-representative of the total student population. Results showed that interests and personality traits were similarly stable over time, but showed different patterns of mean-level change. There was evidence of personality maturation but a lack of cumulative changes in interest levels. For the most part, gender differences in developmental trends were minimal. In addition, latent growth curve analyses revealed broad and specific correlated changes between personality and interests. Changes in general factors of personality and interests were moderately related (r .32), but stronger correlated changes were found among specific personality–interest pairs that share situational content. Overall, results reveal how interests and personality are related across different types of continuity and change. While there was little correspondence between group-level changes, substantial correlated change occurred at the individual level. This means that when a person’s personality changes, their interests tend to change in predictable ways (and vice versa). Integrative theories that link different aspects of psychological functioning can benefit by incorporating these findings.
Perceived Parent-Adolescent Conflict and Social Competence: Moderating Role of Gender

The study examined association between perceived parent adolescent conflict and social competence and whether gender of the adolescents moderated impact of parent-adolescent conflicts on their social competence. The sample of 120 college students (60 boys and 60 girls) who were living with both biological parents was recruited from the public colleges of Lahore. The Conflict Behavior Questionnaire and Social Competence Scale for Adolescents were administered to the participants. Results revealed that there was statistically significant difference between the mean scores of adolescent boys and girls on their perceived adolescent conflict with father (t = 9.41, p <.001) and with mother (t = 2.66, p <.012) however boys’ conflict with their parents was stronger than that of girls. Interestingly, both boys and girls perceived their relationship with the parent of the opposite sex as more conflicting. Parent-adolescent conflicts negatively predicted social competence and gender moderated the relationship between motheradolescent conflict and social competence of adolescents after statistically controlling for demographic variables i.e., age of adolescents, class and family system, unlike the case of father-adolescents conflict. Furthermore, adolescent girls scored significantly higher on social competence than boys (t =2.45, p < .016). The findings have been discussed in regard to gender roles in the cultural environment /settings of Pakistan where a huge gender disparity exists between the sexes. As a developing country, changing family life-style due to urbanization and spread of education in Pakistan appears to bode well in negotiating gender discrepancies and viewpoints for adaptive parent-adolescent relationship. It can, in turn, boost social competence as well, among adolescents.
Masticatory Ability and Nutritional Status in Elderly Population

Age-related changes in oral health may lead to impaired masticatory function. This phenomenon may affect food selection and nutrient intake and lead to malnutrition. Previous studies showed different relationships between masticatory performance and nutritional status. However, similar studies are still limited in Indonesia, especially among the elderly population. To analyze the relationship between masticatory ability and nutritional status using the Mini Nutritional Assessment-Short Form (MNA-SF) among the elderly and the relationship between masticatory ability and nutritional status among the elderly based on the loss of teeth (Eichner Index), denture wearing, and other sociodemographic factors (gender, educational level, and economic status). A cross-sectional study was conducted from 100 patients (age ≥ 60 years) at the Kramat Jati Sub-district Health Center. Subject data was obtained, oral examinations were performed, subject heights and weights were measured, and subjects were interviewed regarding their masticatory abilities and nutritional statuses. There was a significant relationship between masticatory ability and nutritional status (p = 0.009). Significant relationships were also found between two variables: female gender (p = 0.040) and not wearing dentures (p = 0.014). This study shows a relationship between masticatory ability and nutritional status among the elderly population. Clinical article (J Int Dent Med Res 2020; 13(4): 1397-1404)
A greenhouse type solar dryer for small-scale dried food industries: Development and dissemination

In this study, a greenhouse type solar dryer for small-scale dried food industries was developed and disseminated. The dryer consists of a parabolic roof structure covered with polycarbonate sheets on a concrete floor. The system is 8.0m in width, 20.0m in length and 3.5m in height, with a loading capacity about 1,000kg of fruits or vegetables. To ensure continuous drying operation, a 100kW-LPG gas burner was incorporated to supply hot air to the dryer during cloudy or rainy days. Nine 15-W DC fans powered by three 50-W PV modules were used to ventilate the dryer. This dryer was installed for a small-scale food industry at Nakhon Pathom in Thailand to produce osmotically dehydrated tomato. To investigate its performance, the dryer was used to dry 3 batches of osmotically dehydrated tomato. Results obtained from these experiments showed that drying air temperatures in the dryer varied from 35°C to 65°C. In addition, the drying time for these products was 2-3 days shorter than that of the natural sun drying and good quality dried products were obtained. A system of differential equations describing heat and moisture transfers during drying of osmotically dehydrated tomato was also developed. The simulated results agreed well with the experimental data. For dissemination purpose, other two units of this type of dryer were constructed and tested at two locations in Thailand and satisfactory results were obtained.

REMOVAL OF COPPER IN CACHAÇAS USING CLAYS

Increased production and cachaca consumption has stimulated research regarding its quality. It is known that copper can be harmful to human health when it is in concentrated form in the beverage and is ingested in large amounts. Thus, there is a great concern among researchers and producers about the use of adsorbent substances for the removal of excess copper. The kinetic parameters and the adsorption isotherms for copper on kaolinite were studied to evaluate the physical-chemical quality of the cachaca before and after adsorption. K01, K03 and K04 kaolinites presented a maximum adsorption capacity of 97, 95 and 90%, respectively. The kinetic rates followed the pseudo-first-order model, and the adsorption isotherm was best adjusted to the Freundlich model. All the parameters of the control samples were within the limits required by law, except for the aldehydes and copper. After adsorption with clay, the values for some of the parameters were lower and those of others were not significantly different. It was possible to describe 87% of the data with the first and second principal components of the multivariate analysis, and all the samples were different from the control for the parameters analyzed. Thus, these clays can be used for the removal of copper from cachaca, but further studies are necessary.
Inequalities and Changes in Under-Nutrition of Under-Five Children in Bangladesh

Results: Although the prevalence of stunting and underweight has declined and that of wasting has increased, inequalities in under-nutrition have increased between 2004 and 2014. Household wealth and maternal education are the most important determinants of inequalities in childhood malnutrition. Child’s age, birth interval, diarrhea, maternal age and education, working status, household wealth and place of residence are important contributing factors of change in inequalities of malnutrition.
H. Zhuge, Cyber-Physical-Social Intelligence on Human-Machine-Nature Symbiosis, Springer, 2020

Humans evolve with understanding reality and discovering, applying and developing knowledge. An approach to understanding reality is to observe and deal with unknown phenomena and then discover, interpret and verify the underlying principles and rules. Link and dimension are basic means for understanding and representing reality. The natural ecosystem is a subsystem of the nature, which evolves symbiotic networks of various species and natural resources. Changing a symbiotic relation could influence the stability of the network, which provides a condition for one species to influence another species. The outbreaks of many pandemics in history are originated from interactions between humans and other species hosting various viruses. Understanding and maintaining various symbiotic relations between species is an important way to prevent and manage a pandemic. A pandemic caused by a previously unknown virus reflects the unknown fields of reality to a certain extent. A pandemic evolving in a cyber-physicalsocial space can be modelled by a cyber-physical-social relational system consisting of a base network of various relations, various flows, and a superstructure that influences the evolution of the base network. Through modeling and analyzing a pandemic, the application of the model is demonstrated and particular rules and methods are unveiled.
Integral Spectral Analysis (ISA) Applied to AVIRIS Data for Manganese Mineralized Laterites in São João da Aliança /GO, Brazil

In Brazil, the lateritic mantle covers nearly 65% of its territory (Melphi et al., 1988). There lateritic process is responsible for metal accumulation in several areas. The products of the weathering of different rocks constituted important ore deposits. The most important deposits are iron-manganese, from Archean to Neoproterozoic age (Carajás/PA, Quadrilátero Ferrífero/MG, Urucum/MT, Serra do Navio/AP); aluminum, from Cretaceous Alkaline massifs (Southeast), Tertiary continental sediments (Trombetas-Paragominas and Jari/PA), Precambrian metamorphic or volcanic rocks (Central East) and nickel, by the weathering of ultramafic rocks (Barro Alto and Niquelândia/GO) (Melphi et al., 1988). The objective aim of this paper is to show the results about the application of the hyperspectral analysis over mineral-target composed by supergenic manganese mineralization in a tropical country, utilizing espectroradiometry analysis and X-Ray Diffraction. The study area, characterized by middle deposits with high concentration of manganese, is located in S. João D’Aliança District of Goiás State (Baeta et al, 1977 and Guimarães, 1978). Hyperspectral remote sensing data were acquired in some areas in 1995 using NASA’s Advanced Visible and Near-Infrared Imaging Spectrometer (AVIRIS). This survey was part of SCAR-B (Smoke, cloud and radiation-Brazil), a scientific mission among NASA, the Brazilian Space Agency (AEB) and the Brazilian National Space Research Institute (INPE).
GC-MS analysis of essential oil from Anethum graveolens L (dill) seeds extracted by supercritical carbon dioxide

Purpose: To conduct gas chromatography-mass spectrometric (GC-MS) analysis of the chemical compositions of dill seed essential oil (DSEO) obtained by supercritical CO2. Methods: The impact on extraction yield were examined by single factor test, the particle size of dill seed, extraction temperature, time, pressure, as well as CO2 flux. The best extraction conditions were obtained by an orthogonal test. The chemical configurations of essential oil were examined by GC-MS analysis. Results: The optimal extraction conditions included an extraction time of 120 min, particle size of 60 mesh, CO2 flow of 25 L/h, temperature of 40oC, and pressure of 20 MPa. Under these conditions, the yield of essential oil was 6.7 %. Out of 38 recognized compounds, the main ones were D-carvone (40.36 %), D-limonene (19.31 %), apiol (17.50 %), α-pinene (6.43 %), 9-octadecenoic acid (9.00 %) as well as 9,12-octadecadienoic acid (2.44 %). Conclusion: A total of 38 constituents of the essential oil obtained by supercritical CO2 were identified. The findings may provide a theoretical basis for comprehensive utilization of dill seed essential oil (DSEO) from China.
\huntop.ps STATISTICAL VALIDATION OF SIMULATION MODELS: A CASE STUDY

Rigorous statistical validation requires that the responses of the model and the real system have the same expected values. However, the modeled and actual responses are not comparable if they are obtained under different scenarios (environmental conditions). Moreover, data on the real system may be unavailable; sensitivity analysis can then be applied to find out whether the model inputs have effects on the model outputs that agree with the experts’ intuition. Not only the total model, but also its modules may be submitted to such sensitivity analyses. This article illustrates these issues through a case study, namely a simulation model for the use of sonar to search for mines on the sea bottom. The methodology, however, applies to models in general.
The Social Side of Early Human Capital Formation: Using a Field Experiment to Estimate the Causal Impact of Neighborhoods

The behavioral revolution within economics has been largely driven by psychological insights, with the sister sciences playing a lesser role. This study leverages insights from sociology to explore the role of neighborhoods on human capital formation at an early age. We do so by estimating the spillover effects from a large-scale early childhood intervention on the educational attainment of over 2,000 disadvantaged children in the United States. We document large spillover effects on both treatment and control children who live near treated children. Interestingly, the spillover effects are localized, decreasing with the spatial distance to treated neighbors. Perhaps our most novel insight is the underlying mechanisms at work: the spillover effect on non-cognitive scores operate through the child's social network while parental investment is an important channel through which cognitive spillover effects operate. Overall, our results reveal the importance of public programs and neighborhoods on human capital formation at an early age, highlighting that human capital accumulation is fundamentally a social activity.
