Authors: Do Kha Duc , Nguyen Trang Thi Huyen , Nguyen Tuan Anh
Published: October 2018

This paper aims to answer whether there is a difference in the choice and consumption of domestic and imported fruits at supermarkets in Ho Chi Minh city and if yes, whether it can be measured. To answer these questions, we employ the structural equation model (SEM) with four variables, including product quality and feature, brand, price, and personal behavior of consumers. The model is subsequently checked using the confirmatory factor analysis (CFA). Data is obtained from surveys on the fruit consumers in HCMC’s supermarkets conducted from October to December, 2013. Conclusions and suggestions are also offered in the paper.

Published: October 2018

The paper attempts to measure the impact of service quality on customers’ return intention and compare service quality and customers’ return between franchised and self-managed restaurants. Factors and variables of this study are adjusted from DINESERV model. The study is conducted on a sample of 363 customers of franchised and self-managed restaurants in Ho Chi Minh City. The results show that two factors of service quality such as reliability and responsiveness affect customers’ return intention. We also find that there are significantly differences in service quality and customers’ return intention between the franchised and self-managed restaurants. We suggest managerial implications to improve service quality of restaurants accordingly.
Perception and attitude of Vietnamese shoppers towards private labels
Authors: Nguyen Trang Thi Mai
Published: October 2018

Private labels have attracted practioners as well as academics around the world in the past several years. In Vietnam, supermarkets have considered private labels as a key branding strategy. However, they are still under-investigated in the market. For that reason, this study attempts to examine the influence of some key factors such as price consciousness, smart shopper self-perception, supermarket image, and consumer innovativeness on attitude towards private labels. A convenience sample of 196 interviewed shoppers in Ho Chi Minh City was used to test the model. The findings indicate that four hypotheses were supported, in which price consciousness has the strongest impact on attitude towards private labels whereas smart shopper self-perception has a least impact.

SOCIAL SECURITY RIGHTS AND GUARANTEES OF SOUTHERN COMMOM MARKET MIGRANT WORKERS
Authors: Delgado Joedson De Souza , Halik Aline Roberta
Published: October 2018

This article revises literature regarding the portability of resources, which constitute social security savings of the migrant workers who live regular and permanently or temporarily in Southern Common Market region. Based on an intuitive approach, resulting from a reality critical theory, the study starts debating migratory process and human development, which demands mobilizing internal and external savings, in order to finance their insured benefits. For this reason, Social Security International Conventions and Treaties – to be ratified by two or more signatory countries – should to guarantee the portability of social security benefits through simplifying the transference of resources and protecting the rights of MERCOSUR’s migrants. Social security is not only important to build a more equal and fair society, but is also a social right protected by public authorities/law that enhance the economic, financial and social development of a country.
Influence of HammecoTox and Zeolitis on morphological and biochemical indicators of rat's blood under conditions of experimental fumonisin toxicosis
Authors: Brezvyn O.M. , Rudyk G.V. , Guta Z.A.
Published: October 2018

In the article the peculiarities of the influence of fodder additives HammecoTox and Zeolit on the organism of rats under conditions of experimental chronic fumonisin toxicosis are given. The research was carried out under vivarium of State Scientific-Research Control Institute of Veterinary Medicinal Products and Feed Additives. In the experiment, 40 rats of body weight 165–170 g. were used. 4 groups were formed. First group of animals was control, in experimental II, III, and IV groups of animals chronic fumonisin toxicosis was reproduced. Rats were injected intragastrically daily of 90 mg of fumonisin per animal. After the manifestation of clinical signs of fumonisin toxicosis on the 21st day, animals of groups ІІІ-ІV began to feed fodder additives, respectively, rats from group III – HammecoTox, IV – Zeolit. After injection of fumonisin to experimental rats, the morpho-functional state of animals has been gradually changing since the first days. Clinical picture of fumonisin toxicosis in experimental rats at day 14 was manifested by dermo-necrotic effect, it was observed redness and formation of crust on visible mucous membranes, nose, showed swelling and redness of the forelocks. After the analysis of the obtained results of hematological researches on the 14th day in rats of group II under the conditions of experimental fumonisin toxicosis, was revealed a probable increase in the number of leukocytes, was established a tendency for growth, the number of eosinophils, segmental neutrophils, as well as a decrease in the number of lymphocytes, monocytes, compared with the control group. In the analysis of leukograms was noted a tendency to shift the nucleus to the left. These results indicated the presence of inflammatory processes and reduced immune protection of the organism of animals in general. After using of feed additives of HammecoTox and Zeolit under conditions of fumonisin toxicosis, of particular note is the stabilization of hematological parameters, the content of hematocrit, the number of leukocytes, the increase in the content of eosinophils and lymphocytes, which reflects the activation of hematopoiesis in the organism of experimental animals and its protective factors. An increase in the urea content in these groups indicates the recovery of urea-synthesis and urea-excretory liver function. In general, for the period of the conducted searches, the effectiveness of both feed additives in the experimental fumonisin toxicosis has been established. However, it should be noted that more active processes of normalizing the clinical condition of experimental rats when using HammecoTox, which is due to the complex influence of the means on the organism of animals.

Authors: Tjahjanto Hary , Rizal Rahmad
Published: October 2018

Objective: To compare IUD-endometrium (ED) distance and the incident

of malposition postplacental CuT-380A IUD insertion in vaginal

delivery between ring forceps technique and push and push

technique.

Method: This study was a double-blind randomized control trial,

performed in September 2014 until March 2015 at Dr. Kariadi Hospital.

Ring forceps and push and push insertion technique groups

consisted of 25 subjects in each group. Follow-up was performed at

1-2 weeks, 6-8 weeks and >12 weeks after insertion.

Result: The mean of IUD-ED distance in push and push group was

shorter (but not statistically significant) than ring forceps group. The

IUD-ED distance was at 1-2-week follow-up 4.1 (2.2) vs. 4.9 (3.4)

mm; p=0.208, at 6-8-week follow-up: 2.6 (1.8) vs. 3.2 (3.7) mm;

p=0.452, and at > 12-week follow-up: 0.9 (0.8) vs. 1.0 (0.9) mm;

p=0.427, respectively. Malposition was found in 1-2-week follow-up,

but the IUD was changed to the normal position (sagital position in

uterine fundus) at 6-8-week and >12-week follow-up. Up to 3

months of follow-up, there was no occurrence of perforation, expulsion

or pregnancy in both groups. Most of subjects (56% in the

ring forceps, 68% in push and push groups) did not feel painful during

IUD insertion.

Conclusion: Push and push insertion technique clinically tends to

produce IUD-ED distance shorter than ring forceps technique. Both

techniques are comfortable, safe and effective.

Methods: A retrospective cohort study followed for 2 years from

2010 to 2012 of women with adenomyosis were diagnosed by

transvaginal sonography and confirmed histologically. Subjects divided

into women who were treated by adenomyosis resection

(with/without Osada’s technique) and who were underwent hysterectomy.

Results: After the surgery, as many as 40 patients (81.63%) did not

feel any pain (VAS 0), and 9 patients (18.37%) still felt pain. For the

fertility outcome, we had 8 patients (20.51%) getting pregnant naturally

without any fertility intervention. Two patients (5.13%) had

successfully conceived by IVF. According to the type of surgery, from

8 natural pregnancy, 7 patients (87.50%) was underwent conventional

resection of adenomyosis and 1 patients (12.50%) underwent

Osada’s procedures. Two patients who were conceived by IVF, both

of them were underwent Osada’s resection.

Conclusion: Adenomyosis resection both conservative or Osada’s

procedures actually has a better outcome for relieving pain; therefore,

some patients can still have a child.

An Image-Based Fall Detection System for the Elderly
Authors: Lu Kun-Lin , Chu Edward T.-H.
Published: October 2018

Due to advances in medical technology, the elderly population has continued to grow. Elderly healthcare issues have been widely discussed—especially fall accidents—because a fall can lead to a fracture and have serious consequences. Therefore, the effective detection of fall accidents is important for both elderly people and their caregivers. In this work, we designed an Image-based FAll Detection System (IFADS) for nursing homes, where public areas are usually equipped with surveillance cameras. Unlike existing fall detection algorithms, we mainly focused on falls that occur while sitting down and standing up from a chair, because the two activities together account for a higher proportion of falls than forward walking. IFADS first applies an object detection algorithm to identify people in a video frame. Then, a posture recognition method is used to keep tracking the status of the people by checking the relative positions of the chair and the people. An alarm is triggered when a fall is detected. In order to evaluate the effectiveness of IFADS, we not only simulated different fall scenarios, but also adopted YouTube and Giphy videos that captured real falls. Our experimental results showed that IFADS achieved an average accuracy of 95.96%. Therefore, IFADS can be used by nursing homes to improve the quality of residential care facilities.

Authors: Bian Pengyang , Zhang Jingjing , Zhang Chaolan , Huang He , Rong Qun , Wu Haixia , Li Xue , Xu Mengmeng , Liu Yu , Ren Siwei
Published: October 2018

A 56d incubation experiment was conducted to explore the effects of the silk-worm excrement biochar (500 °C, BC) combined with different iron-based materials (FeCl3, FeSO4, and reduced iron powder) on the speciation of cadmium (Cd) and lead (Pb) in a contaminated soil. Application rate of BC and iron-based materials is 1% (W/W) and 0.2% (W/W) of the soil, respectively. At the same time, the soil physicochemical properties, such as pH, cation exchange capacity (CEC), and the structure of soil, were determined in order to explore the influence mechanism of amendments to forms of Cd and Pb in soil. The results show that the stabilization effects on Cd is (BC + FeSO4) > (BC + FeCl3) > (BC + Fe) > (BC) and Pb is (BC + Fe) > (BC + FeSO4) > (BC + FeCl3) > (BC) at the end of incubation, compared with the effect of the control group. The treatment of (BC + FeSO4) is the most effective in terms of the stabilization of Cd and Pb, which makes the percentages of organic-bound and residual Cd and Pb increase by 40.90% and 23.51% respectively. In addition, with different ways of treatment, the pH value and CEC of soil see a remarkable increase by 1.65–2.01 units and 2.01–2.58 cmol·kg−1 respectively. X-ray diffraction (XRD) patterns show that the soil imprisons Cd and Pb in different mineral phases. As such the treatment of (BC + FeSO4) can significantly improve soil environment, increase soil pH value & CEC and exert a relatively good stabilization effect on both Cd and Pb.
Side-Channel Vulnerabilities of Unified Point Addition on Binary Huff Curve and Its Countermeasure
Authors: Cho Sung Min , Jin Sunghyun , Kim HeeSeok
Published: October 2018

Unified point addition for computing elliptic curve point addition and doubling is considered to be resistant to simple power analysis. Recently, new side-channel attacks, such as recovery of secret exponent by triangular trace analysis and horizontal collision correlation analysis, have been successfully applied to elliptic curve methods to investigate their resistance to side-channel attacks. These attacks turn out to be very powerful since they only require leakage of a single power consumption trace. In this paper, using these side-channel attack analyses, we introduce two vulnerabilities of unified point addition on the binary Huff curve. Also, we propose a new unified point addition method for the binary Huff curve. Furthermore, to secure against these vulnerabilities, we apply an equivalence class to the side-channel atomic algorithm using the proposed unified point addition method.
Condition Monitoring of Wind Turbine Blades Using Active and Passive Thermography
Authors: Sanati Hadi , Wood David , Sun Qiao
Published: October 2018

The failure of wind turbine blades is a major concern in the wind power industry due to the resulting high cost. It is, therefore, crucial to develop methods to monitor the integrity of wind turbine blades. Different methods are available to detect subsurface damage but most require close proximity between the sensor and the blade. Thermography, as a non-contact method, may avoid this problem. Both passive and active pulsed and step heating and cooling thermography techniques were investigated for different purposes. A section of a severely damaged blade and a small “plate” cut from the undamaged laminate section of the blade with holes of varying diameter and depth drilled from the rear to provide “known” defects were monitored. The raw thermal images captured by both active and passive thermography demonstrated that image processing was required to improve the quality of the thermal data. Different image processing algorithms were used to increase the thermal contrasts of subsurface defects in thermal images obtained by active thermography. A method called “Step Phase and Amplitude Thermography”, which applies a transform-based algorithm to step heating and cooling data was used. This method was also applied, for the first time, to the passive thermography results. The outcomes of the image processing on both active and passive thermography indicated that the techniques employed could considerably increase the quality of the images and the visibility of internal defects. The signal-to-noise ratio of raw and processed images was calculated to quantitatively show that image processing methods considerably improve the ratios.

Sometimes these models depend on the data dependencies, being easier to describe what has to be done instead of how. Configuration models enable to use a declarative representation of business processes, deciding the most appropriate work-flow in each case. Unfortunately, data dependencies among the activities and how they can affect the correct execution of the process, has been overlooked in the declarative specifications and configurable systems found in the literature. In order to find the best process configuration for optimizing the execution time of processes according to data dependencies, we propose the use of Constraint Programming paradigm with the aim of obtaining an adaptable imperative model in function of the data dependencies of the activities described declarative.

Providing efficient ventilation in road tunnels is essential to prevent severe air pollution exposure for both drivers and pedestrians in such enclosed spaces with heavy vehicle emissions. Longitudinal ventilation methods like commercial jet fans have been widely applied and confirmed to be effective for introducing external fresh air into road tunnels that are shorter than 3 km. However, operating tunnel jet fans is energy consuming. Therefore, for small-scale (~100 m–1 km) road tunnels, mechanical ventilation methods might be highly energetically expensive and unaffordable. Many studies have found that the use of wind catchers could improve buildings’ natural ventilation, but their effect on improving natural ventilation in small-scale road tunnels has, hitherto, rarely been studied. This paper, therefore, aims to quantify the influence of style and arrangement of one-sided flat-roof wind catchers on ventilation performance in a road tunnel. The concept of intake fraction (IF) is applied for ventilation and pollutant exposure assessment in the overall tunnel and for pedestrian regions. Computational fluid dynamics (CFD) methodology with a standard k-epsilon turbulence model is used to perform a three-dimensional (3D) turbulent flow simulation, and CFD results have been validated by wind-tunnel experiments for building cross ventilation. Results show that the introduction of wind catchers would significantly enhance wind speed at pedestrian level, but a negative velocity reduction effect and a near-catcher recirculation zone can also be found. A special downstream vortex extending along the downstream tunnel is found, helping remove the accumulated pollutants away from the low-level pedestrian sides. Both wind catcher style and arrangement would significantly influence the ventilation performance in the tunnel. Compared to long-catcher designs, short-catchers would be more effective for providing fresh air to pedestrian sides due to a weaker upstream velocity reduction effect and smaller near-catcher recirculation zone. In long-catcher cases, IF increases to 1.13 ppm when the wind catcher is positioned 240 m away from the tunnel entrance, which is almost twice that in short-catcher cases. For the effects of catcher arrangements, single, short-catcher, span-wise, shifting would not help dilute pollutants effectively. Generally, a design involving a double short-catcher in a parallel arrangement is the most recommended, with the smallest IF, i.e., 61% of that in the tunnel without wind catchers (0.36 ppm).

Vanadium redox flow batteries (VRFBs) offer great promise as a safe, cost effective means of storing electrical energy on a large scale and will certainly have a part to play in the global transition to renewable energy. To unlock the full potential of VRFB systems, however, it is necessary to improve their power density. Unconventional stack design shows encouraging possibilities as a means to that end. Presented here is the novel concept of variable porous electrode compression, which simulations have shown to deliver a one third increase in minimum limiting current density together with a lower pressure drop when compared to standard uniform compression cell designs.

The aim of this study was to evaluate the effects of high fat diet with or without grape juice during the pregnancy on gestational weight gain, biochemical parameters, and oxidative stress in plasma and liver from Wistar rats. Forty-nine rats were divided into four groups: control diet group (CD), high fat diet (HFD), grape juice and control diet (PGJCD), and grape juice and high fat diet (PGJHFD). During the treatment the weight gain of the rats was tracked. They had free access to their respective diets during 42 days of treatment. After offspring weaning, the mother rats were euthanized and blood and liver were collected. The high fat diet increased the total cholesterol and triglycerides serum levels as well as carbonyl levels in the liver, however this diet reduced the high-density lipoprotein (HDL) and urea levels in serum. Grape juice consumption reduced gestational body weight gain. In liver, the juice consumption increased sulfhydryl levels and reduced the superoxide dismutase (SOD) activity and TBARS level, in serum the consumption reduced aspartate aminotransferase (AST) and TBARS. We can conclude that the consumption of a diet rich in fat can promotes harmful effects on health during pregnancy, however the consumption of grape juice seems to be an important alternative to prevent oxidative damages and to promote the improvement of health.
Ginger and Testosterone
Authors: Banihani Saleem Ali
Published: October 2018

Enhancing and protecting testosterone production is one target for many scientists because of its crucial role as a primary sex hormone in males. Several in vivo trials have utilized different dietary supplements and medicinal plants to enhance testosterone production in males. Since 1991, various in-vivo, as well as basic research studies, have discovered a link between ginger (Zingiber officinale) and testosterone. However, such a link has not yet been collectively reviewed. This review systematically discusses and summarizes the effect of ginger and ginger extracts on testosterone. To achieve this contribution, we searched the PubMed, Scopus, and Web of Science databases for English language articles (full texts or abstracts) from November 1991 through August 2018 using the keywords “ginger” and “Zingiber officinale” versus “testosterone”. Additionally, the references from related published articles were also reviewed, only if relevant. In conclusion, the mainstream of research that links ginger to testosterone demonstrated that ginger supplementation, particularly in oxidative stress conditions, enhances testosterone production in males. The mechanisms by which this occurs mainly by enhancing luteinizing hormone (LH) production, increasing the level of cholesterol in the testes, reducing oxidative stress and lipid peroxidation in the testes, enhancing the activity of the antioxidant enzymes, normalizing blood glucose, increasing blood flow in the testes, increasing testicular weight, and recycling testosterone receptors. However, the effect of ginger on testosterone is not yet confirmed in humans. Therefore, clinical studies in this context of research are imperative.

To address Americans’ general attitudes and behavioral intentions toward adult children who are estranged from their parents, the current study employed online survey data from 151 Americans recruited through Amazon MTurk. Their responses revealed negative stereotypes (e.g., childish, ungrateful) and positive stereotypes (e.g., independent, strong) of the adult child who is estranged, as well as negative assessments of the parent who is estranged. Generally, participants perceived the adult children as more competent than warm. Compared to other participants in this sample, those participants who were estrangers or estrangees themselves held more positive attitudes overall, including more positive perceptions of estranged children’s warmth and competence. In response to open-ended survey questions asking participants how they would communicate with someone they knew to be estranged, common responses were avoidance of family-related topics, (heightened) physical distance, and accommodation to the needs of the person who is estranged. Implications are discussed surrounding the lack of warmth associated with those experiencing estrangement.

Accurate repeatability of experimental data is the basis of professional scientific research. In this study we analyzed three consecutive experiments: The subjects had to complete a questionnaire three times under similar conditions within a 2–3 week interval to ensure reproducibility of the original data from experiment to experiment, using the method of test–retest reliability. Absolute reliability was assessed by the standard error of measurement (SEM) and smallest real difference (SRD). The relative reliability was estimated by calculating the intraclass correlation coefficients (ICC3,1) (average measures) and the results demonstrate almost perfect agreement. The social interaction model was applied for organization of the experimental study. In this virtual model, the participants had to choose one of three types of reactions (i.e., attacking, avoiding, or friendly) to stimuli-facial expressions (i.e., angry, fearful, sad, neutral, and happy). The results show significant correlation between personal characteristics and social interactions. The results of the influence of such personal characteristics as agreeableness, collectivism, extraversion, neuroticism, and those shown on the Relational-interdependent Self-Construal Scale and State-Trait Anxiety Inventory are highly consistent with other researchers’ data and common sense.

Purpose: To propose a risk classification scheme for locoregionally advanced (Stages III and IV) head and neck squamous cell carcinoma (LA-HNSCC) by using the Wu comorbidity score (WCS) to quantify the risk of curative surgeries, including tumor resection and radical neck dissection. Methods: This study included 55,080 patients with LA-HNSCC receiving curative surgery between 2006 and 2015 who were identified from the Taiwan Cancer Registry database; the patients were classified into two groups, mortality (n = 1287, mortality rate = 2.34%) and survival (n = 53,793, survival rate = 97.66%), according to the event of mortality within 90 days of surgery. Significant risk factors for mortality were identified using a stepwise multivariate Cox proportional hazards model. The WCS was calculated using the relative risk of each risk factor. The accuracy of the WCS was assessed using mortality rates in different risk strata. Results: Fifteen comorbidities significantly increased mortality risk after curative surgery. The patients were divided into low-risk (WCS, 0–6; 90-day mortality rate, 0–1.57%), intermediate-risk (7–11; 2.71–9.99%), high-risk (12–16; 17.30–20.00%), and very-high-risk (17–18 and >18; 46.15–50.00%) strata. The 90-day survival rates were 98.97, 95.85, 81.20, and 53.13% in the low-, intermediate-, high-, and very-high-risk patients, respectively (log-rank p < 0.0001). The five-year overall survival rates after surgery were 70.86, 48.62, 22.99, and 18.75% in the low-, intermediate-, high-, and very-high-risk patients, respectively (log-rank p < 0.0001). Conclusion: The WCS is an accurate tool for assessing curative-surgery-related 90-day mortality risk and overall survival in patients with LA-HNSCC.

Aberrant DNA methylation is a potential mechanism underlying the development of colorectal cancer (CRC). Thus, identification of prognostic DNA methylation markers and understanding the related molecular functions may offer a new perspective on CRC pathogenesis. To that end, we explored DNA methylation profile changes in CRC subtypes based on the microsatellite instability (MSI) status through genome-wide DNA methylation profiling analysis. Of 34 altered genes, three hypermethylated (epidermal growth factor, EGF; carbohydrate sulfotransferase 10, CHST10; ependymin related 1, EPDR1) and two hypomethylated (bone marrow stromal antigen 2, BST2; Rac family small GTPase 3, RAC3) candidates were further validated in CRC patients. Based on quantitative methylation-specific polymerase chain reaction (Q-MSP), EGF, CHST10 and EPDR1 showed higher hypermethylated levels in CRC tissues than those in adjacent normal tissues, whereas BST2 showed hypomethylation in CRC tissues relative to adjacent normal tissues. Additionally, among 75 CRC patients, hypermethylation of CHST10 and EPDR1 was significantly correlated with the MSI status and a better prognosis. Moreover, EPDR1 hypermethylation was significantly correlated with node negativity and a lower tumor stage as well as with mutations in B-Raf proto-oncogene serine/threonine kinase (BRAF) and human transforming growth factor beta receptor 2 (TGFβR2). Conversely, a negative correlation between the mRNA expression and methylation levels of EPDR1 in CRC tissues and cell lines was observed, revealing that DNA methylation has a crucial function in modulating EPDR1 expression in CRC cells. EPDR1 knockdown by a transient small interfering RNA significantly suppressed invasion by CRC cells, suggesting that decreased EPDR1 levels may attenuate CRC cell invasion. These results suggest that DNA methylation-mediated EPDR1 epigenetic silencing may play an important role in preventing CRC progression.
A Buoyant, Microstructured Polymer Substrate for Photocatalytic Degradation Applications
Authors: Bertram John R. , Nee Matthew J.
Published: October 2018

Microbubble fabrication of poly(dimethylsiloxane) (PDMS) beads with incorporated TiO2 provides a low-density, microstructured photocatalyst that is buoyant in water. This approach surmounts many of the challenges traditionally encountered in the generation of buoyant photocatalysts, an area which is critical for the implementation of widespread environmental cleaning of organic pollutants in water resources. Because the incorporation into the polymer bead surface is done at low temperatures, the crystal structure of TiO2 is unaltered, ensuring high-quality photocatalytic activity, while PDMS is well-established as biocompatible, temperature stable, and simple to produce. The photocatalyst is shown to degrade methylene blue faster than other buoyant, TiO2-based photocatalysts, and only an order of magnitude less than direct suspension of an equivalent amount of photocatalyst in solution, even though the photocatalyst is only present at the surface of the solution. The reusability of the TiO2/PDMS beads is also strong, showing no depreciation in photocatalytic activity after five consecutive degradation trials.
