ASSESSMENT OF DIETARY CHALLENGES FACED BY SUB-SAHARAN IMMI- GRANTS RESIDING IN THE GAUTENG PROVINCE: A PILOT STUDY

Migration poses a unique food challenge that has led to immigrant households failing to maintain their traditional food diets. Despite the growing number of Sub-Saharan immigrants living in South Africa, information regarding their dietary challenges and habits upon settlement in South Africa is limited. A descriptive study involving immigrant households (n=34) was primarily used to pre-test a questionnaire that was undertaken by immigrants to assess the challenges they face with regard to their ability to continue with and maintain their traditional diets. Data relating to socio-demographic characteristics, such as continuity with ethnic food culture and the problems faced by SubSaharan immigrants with regard to them retaining their traditional food culture was collected. All the respondents indicated that they treasured and maintained their traditional food culture, albeit to varying degrees. Overall, high prices (64,6%), limited variety (64,5%), the quality of food (71%), the unavailability of traditional foods (58,7%) and a lack of shops selling traditional food (76,5%) were identified as major barriers to them retaining their traditional food culture. This is the first study to assess the challenges faced by immigrants living in South Africa with regard to them accessing their traditional foods and maintaining their traditional diets. The findings of the study suggest that Sub-Saharan immigrants living in South Africa find it difficult to access their traditional foods and that this lack of access could predispose them to adopt poor eating habits, however, there is still a need for a larger study with more respondents to test these findings. The findings of the study also revealed that there were lot of similarities between the eating patterns of South Africans and those of immigrants from Southern African countries. — Mrs TP Mbombo-Dweba* Department of Agriculture and Animal Health University of South Africa South Africa Tel: +27 (0)11 471 2264 Fax: +27(0)11 471 2260 Email: mbombtp@unisa.ac. za *Corresponding author — Dr AO Agyepong Department of Agriculture and Animal Health University of South Africa South Africa Tel: +27 (0)11 471 2264 Fax: +27(0)11 471 2260 Email: agyepao@unisa.ac. za — Dr JW Oguttu Department of Agriculture and Animal Health University of South Africa South Africa Tel: +27 (0)11 471 3353 Fax: +27(0)11 471 2260 Email: JOguttu@unisa.ac. za — Prof CA Mbajiorgu Department of Agriculture and Animal Health University of South Africa South Africa Tel: +27 (0)11 471 3590 Fax: +27(0)11 471 2260 Email: mbajica@unisa.ac. za
Altered cortical gyrification in adults who were born very preterm and its associations with cognition and mental health

Background The last trimester of pregnancy is a critical period for the establishment of cortical gyrification and altered folding patterns have been reported following very preterm birth (< 33 weeks of gestation) in childhood and adolescence. However, research is scant on the persistence of such alterations in adulthood and their associations with cognitive and psychiatric outcomes. Methods We studied 79 very-preterm adults and 81 age-matched full-term controls. T1-weighted images were used to measure local gyrification index (LGI), indicating the degree of folding across multiple vertices of the reconstructed cortical surface. Group and group-sex LGI differences were assessed using per-vertex adjustment for cortical thickness and overall intracranial volume. Within-group correlations were also computed between LGI and functional outcomes, including general intelligence (IQ) and psychopathology. Results Very preterm adults had significantly reduced LGI in extensive cortical regions encompassing the frontal, anterior temporal and occipito-parietal lobes. Alterations in lateral fronto-temporal-parietal and medial occipito-parietal regions were present in both males and females, although males reported more extensive alterations. In both very preterm adults and controls, higher LGI was associated with higher IQ and lower psychopathology scores, with the spatial distribution of these associations substantially differing between the two groups. Conclusions Very preterm adults’ brains are characterized by significant and widespread local hypogyria and these abnormalities might be implicated in cognitive and psychiatric outcomes. Gyrification reflects an early developmental process and provides a fingerprint for very preterm birth.
Temporal fluctuations in context ethnic diversity over three decades predict implicit national inclusion of Asian Americans

The present research examined whether temporal fluctuations in context ethnic diversity account for current levels of implicit ethnic-American associations. Temporal fluctuations in ethnic diversity at the metropolitan level were assessed using data from four decennial U.S. censuses (1980–2010) and distinguishing three dimensions of context ethnic diversity (minority representation, variety, and integration). Project Implicit data (2011–2017) indexed the extent to which American identity was implicitly associated with European Americans over Asian Americans (i.e., American = White associations). Data were analyzed using multilevel modeling (N = 152,011, nested within 226 metropolitan areas). Steeper increases in the proportion of Asian Americans were related to weaker implicit (but stronger explicit) American = White associations. Increases in ethnic integration accounted for stronger implicit American = White associations when integration fluctuations reflected accelerating rather than decelerating trends. These results suggest that current levels of implicit ethnic-national associations are linked to complex patterns of ethnic diversity fluctuations.
Analysis of additive manufactured polymer optical waveguides: measurement and simulation of their waviness

This paper analyzes an approach for additively manufacturing polymer optical waveguides. The production process includes flexographic printing of conditioning lines (5 μm height) on a substrate, which are used as guiding barriers in the subsequent printing of the optical core. The core is additively printed (up to 50 μm in height) with an aerosol jet printer, filling the gap between the conditioning lines. The conditioning lines do not only enhance the contact angle of the polymer, which results in a higher cross section of the waveguides, but also improve the straight edges of the printed waveguides. We show that the quality of the conditioning lines is directly correlated to the waviness of the waveguides. Consequently, the analyses of the waviness of the conditioning lines classifies the quality of the fabricated waveguides. However, the waviness of the waveguides can also be considered in optical simulations. In this paper we show how we derive a waveguide model with waviness by fitting a single sine function onto the topological data of the conditioning lines. With this model a variation of the waviness can easily be simulated and goals for fabrication can be set. With the simulations it is possible to verify that the measured waviness (period of 559.5 μm and an amplitude of 4.99 μm) does not affect the optical quality of the waveguides.
Widening of Reinforced Concrete Bridges – Extension of Pier Cap Beams with CFRP Composites

Increase in traffic load dictates widening highway bridges rather than construction of new bridges, as it offers an economical solution. Highway bridge widening is usually accomplished by the construction of additional new bridge piers, however, large amount of construction work and extensive use of heavy plant and machinery could result in very high cost. For limited widening of bridges, e.g. addition of one driving/emergency lane, extension of the pier cap beam offers an attractive solution. Due to additional load resulting from the widened bridge, strengthening of extended cap beams may be needed. In addition, depending on the strength of the existing pier column, limited strengthening of the column will probably be needed. This research project presents a bridge cap beam extension and reinforcing system, which is considered an alternative of constructing new piers for bridge widening projects. Experimental results and numerical modeling of quarter-scaled reinforced concrete hammerhead non-prismatic pier cap beams, extended on verges and reinforced with different CFRP systems are presented, followed by development of a practical analytical model. In addition, a column strengthening system, which provides a continuous load path to transfer additional moment to the foundation, was presented in this study. The experimental work was to investigate the structural performance of this particular type of beams with different reinforcing systems, such as concrete jacket, CFRP sheets and pre-saturated CFRP laminates with various anchor systems. Thirteen pier cap beam specimens were tested to evaluate the effect of the reinforcing systems on ultimate strength, stiffness and ductility. In addition, five full-scaled rectangular RC columns strengthened with either concrete jacket or vertical CFRP plates were tested under cyclic loading, flexural and cyclic performance of strengthened columns, and strain distribution on CFRP composites were investigated. A numerical study based on finite element modeling was performed to investigate the failure mechanism of tested beams. A 3-D finite element model was developed and verified against experimental results. A good agreement between finite element results and experimental results was achieved in terms of failure mode, ultimate capacity and load-deflection response. The experimental work and finite element results demonstrated the feasibility of proposed cap beam extension system. All of the tested reinforcing systems are effective in improving flexural strength of the extended cap beams. Among the investigated reinforcing systems, the fully wrapped CFRP sheet offers the most efficient solution for proposed system. Based on these observations, an iterative based simple practical analytical model was developed to predict the ultimate capacity of extended cap beams with CFRP reinforcing systems. A few design and construction recommendations are presented at the end of the dissertation. Widening of Reinforced Concrete Bridges – Extension of Pier Cap Beams with CFRP Composites
Association between sources of sexuality education, sexual beliefs and behaviours in Lebanese young adults: a university-based cross-sectional study

ABSTRACT This study assessed the association between sources of sexuality education, sexual beliefs and behaviour among Lebanese youth. 451 unmarried students at a private university, mean age 20.25 (±1.41) years, participated in the study. Main sources of information were teachers, mothers, internet and friends. Respondents wished for increased involvement of fathers and doctors in their sexuality education. There was a positive association between receipt of school classes on reproductive health and adoption of protective behaviour at first sexual experience (OR = 4.09, p < 0.05). A Sexual Belief Index (SBI) was calculated as a mean score on 18 items related to sexual permissiveness (Cronbach’s alpha = 0.83). Sex and classes on reproductive health predicted a rise in SBI. The timing of classes, namely earlier introduction, and communication with family and religious figures predicted a decrease in SBI. The SBI was positively associated with sexual activity (OR = 3.68, p = 4.399e-07), first sex at <17 years (OR = 5.262, p = 0.0099) and engagement in one-night stands (OR = 4.195, p = 0.0001). Students who engaged in same-sex sexual experiences had higher odds of contracting STIs (OR = 12.7, p = 0.0001). Findings reveal the need to include sexual health in school curricula; train parents, physicians and teachers as information providers and moderators of SBI; and improve access to youth-friendly services.
Health, use of health care services and health-related behaviours among international exchange students in Finland

Huuskonen, Elina. Health, use of health care services and health-related behaviours among international exchange students in Finland. 65p. , 3 appendices. Language: English. Helsinki, Spring 2018. Diaconia University of Applied Sciences. Degree program in global health care. Master of health care (Sairaanhoitaja YAMK). Background: As international student exchange grows more popular among University students globally, so does the need for studies regarding their health. More than 10,000 international exchange students come to Finland every year. The health of Finnish students in Universities and Universities of Applied Sciences is being thoroughly studied every four years, while the health of the exchange students remains unknown. Purpose: This study seeks to illustrate the health status, use of health care services, and health-related behaviours that affect the health of the exchange students in Finland. Methods: A self-administered on-line questionnaire was sent to all Finnish Universities and UASs through a mailing list. The survey was open for six weeks during spring term 2017. Out of the total of 346 responses 318 were included in the analysis. Data analyses were carried out by using MS Excel. The data were described with frequency tables, cross-tabulation and descriptive statistics. Results: Approximately two-thirds of the respondents were female. Most were between 20 and 24 years old and of European origin. The exchange students experienced mostly good health and few symptoms, though one-third of female students had problems with sleep. Women more often reported poorer health and more symptoms than men. Anxiety was common in respondents who experienced frequent feelings of loneliness or homesickness. Approximately 20% of the respondents used health care services while in Finland, while another 20% failed to seek health care despite the need for it due to feeling it was too expensive or too complicated. AUDIT survey showed that most exchange students used alcohol moderately. Most respondents brushed their teeth twice a day, but using tooth paste containing fluorine, dental floss or products sweetened with xylitol was rarer. Discussion: The results showed that, for the most part, the health status of exchange students was fairly similar to that of Finnish students. Further studies and possible interventions could be beneficial based on findings regarding problems with sleep among female students, dental care practices, rates of anxiety in certain groups, lacking condom use, rates of free-time physical exercise, and inability to seek health care services while in Finland.

Comparison of dissection-based vs. internet-based pelvic anatomy education for 3rd year medical students

With the inclusion of various technologies, teaching anatomy to medical students is in the midst of a transition in medical schools. The traditional anatomy curriculum based on topographical structural anatomy taught by didactic lectures and complete dissection of the body with personal instruction, has been replaced by a multiple range of special study modules, problem-based workshops, computer based education, plastic models, just to name a few of teaching tools employed. Most new tools in the literature are descriptive and lack efficacy data. In this study we compared an internet-based anatomy module with traditional methods taught to the 3 rd year medical students. During 2008-2014, pelvic anatomy was taught to 3 rd year medical students using dissection-based (DB) and internet-based (IB) methods. This module was composed of 30 minutes of a lecture with PowerPoint, 30 minutes of anatomy videos, 30 minutes of dissection lab, and a post-test at the conclusion. The 30 min of anatomy video course consisted of 30 minutes session designed to address the perineal external and internal anatomy, perineal muscles and neurovasculature, caudad view of levator ani muscle, lateral view of pelvic organs and vasculature, cephalad view of pelvic organs and nerves, and cephalad view of the levator ani muscle. The same course material and the PowerPoint presentations used were converted to digital format and taught as an internet-based (IB) module without inclusion of a dissection lab. We compared the students’ performance at final assessment between DB vs. IB groups. Comparison between DB and IB groups revealed significantly (P<0.0001) higher mean score for the IB group in all learning objectives except perineal Internal Anatomy (P= 0.431). 3 rd year medical students demonstrated higher pelvic floor anatomy scores after completing an internet-based module compared to a traditional dissection based course.
Image Encryption Using Fractional Order Linear-Nonlinear Chaos

A fractional order chaos system is first designed. It is a linear-nonlinear hybrid using fractional order logistic map. The fractional order chaos system is closer to the real nature phenomena and has better cryptography features than the integer order chaotic systems in dynamics, such as larger range of key space and almost no periodic windows in bifurcation diagrams. Then, we propose an image encryption scheme employing the superior chaotic features of the fractional order chaos system. Which chaotic sequences generated are used for permutation and addition/subtraction operation of encryption depends on the plaintext image. Security analysis and test results indicate that our encryption scheme has a high efficiency and superior security.
The Reduction of Anxiety and Blood Sugar Level with Group Cognitive-Behavior Therapy in Men and Women with Type II Diabetes: An Experimental Study

Article type: Original Article Background: Although psychological distress can interfere with diabetes care, the effectiveness of Group Cognitive-Behavior Therapy in improving diabetes outcomes is unknown. Objectives: The purpose of this study was to reduce anxiety symptoms and improve glycemic control in diabetic patients. The samples were 24 diabetic patients (12 in experimental group and 12 in control group) aging from 40 to 60 years. Materials and Methods: The anxiety symptoms and glycemic control were assessed prior to and following Group Cognitive-Behavior Therapy (CBT) using self-report instruments and through measuring glycosylated hemoglobin and fasting blood sugar (FBS). SPSS software version 16 was also used for statistical analysis of the study. Results: The results, analyzed by the analysis of covariance, indicated that after group-therapy, there were no significant differences between the two groups in as far as the means of FBS concentration. Moreover, a significant decrease was seen in hemoglobin A1c (HbA1c) concentration after group-therapy in the experimental group. As far as anxiety, no significant difference was observed between the two groups following the therapy; however, after group therapy, the anxiety of the women in the experimental group underwent a significant decrease. In addition, a reduction in anxiety symptoms was observed post group-therapy, and the reoccurred significant changes in the glycemic control. Conclusion: The findings of this pilot study suggest that group-therapy is a feasible intervention for patients with diabetes and anxiety symptoms. However, further research is needed if a development is to be had regarding the interventions that improve glycemic control.
Risk Factors of Postpartum Depression at Dr. Moewardi Hospital, Surakarta

Background : Postpartum depression is one of the emotional disturbances that results from failure to postpartum psychological adaptation process. The global prevalence of postpartum depression is 10-15%. This study aimed to analyze the risk factors of pregnancy on the incidence of postpartum depression. Subje cts and Met hod: This was an analytic and observational study with a cross-sectional design. The study was conducted at Dr. Moewardi hospital, from December 2017 to January 2018. A total sample of 150 postpartum mothers was selected for this study by exhaustive sampling. The dependent variable was postpartum depression (PPD). The independent variables were maternal age, stress, parity, unwanted pregnancy, type of labor, family income, family support, and domestic violence. The data were collected by questionnaire and analyzed by path analysis model. Results : Postpartum depression was directly and positively affected by psychological stress (b= 2.15; 95% CI= 1.17 to 3.13; p<0.001), delivery type (b= 1.27; 95% CI= 0.32 to 2.21; p= 0.008), and unwanted pregnancy (b= 1.57; 95% CI= 0.57 to 2.58; p= 0.002). Postpartum depression was directly but negatively affected by family income (b= -1.52; 95% CI= -2.51 to -0.54; p= 0.002), parity (b= -1.24; 95% CI= -2.21 to -0.28; p= 0.011), and family support (b= -1.31; 95% CI= -3.28 to -0.24; p= 0.016). Psychological stress increased with domestic violence (b= 2.68; 95% CI= 0.64 to 4.73; p= 0.010) and decreased with maternal age (b= -0.91; 95% CI= -1.68 to -0.13; p= 0.022). Parity increased with maternal age (b= 1.66; 95% CI= 0.79 to 2.53; p<0.001). Domestic violence decreased with maternal age (b= -1.34; 95% CI= -2.85 to 0.16; p= 0.081). Conslusion : Psychological stress, delivery type, unwanted pregnancy, family income, parity, and family support, are direct risk factors for postpartum depression.

GAN for Recommendation System

In our day there are many approaches for recommendation generation, however several unsolved problems still exist. In our work we study the potential of Generative Adversarial Networks to generate relevant recommendations and compare the proposed approach with another recommendations system based on neural networks. We found that recommendation system based on GANs can successively compete with state-of-the-art network in the field of recommendation generation and suggest, that GAN recommendation system have high potential.
Preferences and Predictors of Aging in Place: Longitudinal Evidence from Melbourne, Australia

ABSTRACT This article reports older Australians' preferences for aging in place and predictors of their subsequent experiences drawing on a longitudinal study in Melbourne over 16 years. At baseline, 40% had lived in their homes for 30 or more years and the majority had preference for aging in place. However, the proportion continuing to do so was lower, with reducing independence being a major barrier. Women, renters, those not living with a partner, or those with depressive symptoms were most vulnerable, while home ownership, socioeconomic resources, neighborhood satisfaction, and home modifications were positively associated with aging in place.
