Published: August 2018

Purpose: As the importance of information quality has become prominent in the internet commerce, curation techniques are also stands out as well. Therefore, many services on e-commerce applied with curation techniques to satisfy their consumers. However, besides the fact that plenty of advantages from curation commerce, the growth of curation commerce websites have been slowdown. Thus, this paper is to investigate factors influencing curatiaxon commerce websites’ consumer loyalty intentions for enhancing the competitiveness of curation commerce websites.Methodology/Approach: This study sets independent variables regarding provider recommendation and consumer review simultaneously and verifies to see how each factors affect to consumer’s loyalty intention through perceived deception and satisfaction in the curation commerce website. We applied structural equation model to verify the hypothesis and conduted a survey on consumer who had buying expriences in Korean curation commerce website.Findings: The results of this study show what fators significantly affect to loyalty intention. Consumers on curation commerce mostly tend to be affected by other consumers’ review and they only affected by presentation of product among provider recommedations. We conducted an important mediating effect of satisfaction between perceived deception and loyalty intention. Furthermore, because curation commerce is a relatively new concept, this attempt could form the basis for research on cuartion commerce.Research Limitation/implication: This research only collected sample data form curation commerce websites users in Korea and because young consumers onsistute the majority of the respondednts, generalizing the findings to individuals of all ages and nations is difficult.Originality/Value of paper: This paper is the first study applying product recommendation and consumer review simultaneouly as an independent variable. These attempts enable to reflect more specific and practical behavior of consumers. Effect of satisfaction on loyalty and relationship between deception and loyalty are well documented in the offline and online retail context. This study expands and verifies estabilshed relationship among the variables on the lastest commerce website.

Published: August 2018

Purpose: The purpose of this paper is to present the results of an analysis and evaluation of data on employee turnover based on deep data mining using association rules and decision trees in a specific organisation.Methodology/Approach: For the analysis, we chose deep data mining methods, primarily a search for association rules using the Apriori algorithm in the R programming language. For the sake of supplementation and comparison of results, data were also analysed using the predictive decision trees method, applying the C5.0, rpart and ctree algorithms in the R program.Findings: The results of the analyses showed that observing the basic principles of correct communication from the beginning of an employment relationship, or during hiring, is justified. Communication and regular conversations between a superior and employees can help identify problems earlier, address them and reduce the number of people leaving the company. The results of the analysis helped the organisation to set measures to reduce the number of an employee leaving.Research Limitation/implication: A limiting factor in performing such analyses is the availability of quality data in the required quantity. Our most significant advantage when performing our analysis was that quality data were available. To create the final structure of the required data set, we used data from the organisation’s internal information systems.Originality/Value of paper: This contribution offers a new approach to analysing data on employee turnover, whose essence is that we need to find the most interesting and frequent correlations in a significant amount of data.
Pyrrhonian Argumentation: Therapy, Dialectic, and Inquiry
Authors: Machuca Diego E. 
Published: August 2018

Abstract
The Pyrrhonist’s argumentative practice is characterized by at least four features. First, he makes a therapeutic use of arguments: he employs arguments that differ in their persuasiveness in order to cure his dogmatic patients of the distinct degrees of conceit and rashness that afflict them. Secondly, his arguments are for the most part dialectical: when offering an argument to oppose it to another argument advanced by a given dogmatist, he accepts in propria persona neither the truth of its premises and conclusion nor the validity of its logical form. Thirdly, he avails himself of arguments in his own open-minded inquiry into the truth about a wide range of topics. Fourthly, Pyrrhonian argumentation is oppositional inasmuch as it typically works by producing oppositions among arguments that appear to the Pyrrhonist to be equipollent. In this article, I focus on the first three features with the aim of both shedding some light on them and determining whether they are in tension or coherently relate to each other.

Abstract
Ischemic-reperfusion injury of the small intestine is an acute clinical condition with high mortality rate. This study describes the changes in levels of phenylalanine and tryptophan metabolites in intestinal homogenates and urine samples of Wistar male rats after 60 minutes of mesenteric ischemia and different reperfusion periods (1, 24, 30 hours) in comparison with a control group without the ischemia. The ischemic-reperfusion injury was quantified by the histopathological injury index. The levels of serotonin, epinephrine, and norepinephrine were determined in the intestinal homogenate and epinephrine, vanillylmandelic acid, and the 5-hydroxyindoleacetic acid was analyzed in urine using the HPLC method. The statistically significant increased level of serotonin, epinephrine and norepinephrine were detected in the intestinal samples after 24 hours of reperfusion (p<0.01); even the most elevated serotonin level was observed after one hour of reperfusion (p<0.001). A statistically significant decreased level of vanillylmandelic acid was observed after one hour of reperfusion, but it significantly increased after 24 hours (p<0.05) in urine. The elevated level of the 5-hydroxyindoleacetic acid after one hour and 24 hours after reperfusion (p<0.05) were determined in the urine. The most significant elevated epinephrine level was observed after 24 hours of reperfusion (p<0.001) in urine. Results showed a potential role of serotonin as an early biomarker (after one hour of reperfusion) of small intestinal damaged homogenate, while the best predictor of intestinal injury in urine was epinephrine, which was elevated after 24 hours.

Authors: Mohammed Ahmed , Mahmood Wael 
Published: August 2018

Abstract
In this study, over 1000 data from the several research studies was used to characterize and compare the density, strengths, modulus, flexural strength, porosity and the ultimate shear strengths of the calcium rocks. The gypsum rock data were statistically analyzed, quantified and compared with the limestone rock data. The ranges of the densities for gypsum rock (CaSO4·2H2O) and limestone rock (CaCO3) were 2.10 to 2.83 gm/cm3 and 1.70 to 2.75 gm/cm3, respectively. The compressive and tensile strengths of the gypsum and limestone rocks varied from 2 MPa to 250 MPa and 1.8 MPa to 25 MPa, respectively. Vipulanandan correlation model was effective in relating the modulus of elasticity, flexural strength, with the relevant strengths of the rocks. A new nonlinear Vipulanandan failure criterion was developed to better quantify the tensile strength, pure shear (cohesion) strength and predict the maximum shear strength limit with applied normal stress on the gypsum and limestone rocks. The prediction of the failure models for the two rock types was also compared to the Mohr-Coulomb failure model. The Vipulanandan failure model predicted the maximum shear strength limit was, as the Mohr-Coulomb failure model does not have a limit on the maximum shear strength. With the Vipulanandan failure model based on the available data, the maximum shear strengths predicted for the gypsum and limestone rocks were 64 MPa and 114 MPa, respectively.

Published: August 2018

Abstract
Slovenia is considered as the cradle of karst geotourism as cave tourism started there as early as the Middle Ages. To date more than 12,000 caves were discovered from which 22 have the status of tourist caves. From these, 10 were assessed using the M-GAM model (Modified Geosite Assessment Model) to gain information for better future management strategies. The results show that visitors of Slovenian tourist caves mostly appreciate their natural values, as they prefer caves without major tourism infrastructure and they pay attention to their protection status. The model also confirmed that the two most important tourist caves (Postojna Cave and Škocjan Caves) have the leading geotourism role and that the management of tourist caves via a regional park as is the case of Škocjan Caves is an example of good practice.
Radical transfer system in the enzymatic dehydrogenative polymerization (DHP formation) of coniferyl alcohol (CA) and three dilignols
Authors: Matsushita Yasuyuki , Okayama Masaya , Aoki Dan , Yagami Sachie , Fukushima Kazuhiko 
Published: August 2018

Abstract
No clear picture has yet been elaborated concerning the mechanism of lignin growth, and thus this topic is the focus of the present paper. Namely, the enzymatic dehydrogenative polymerization (DHP formation) of coniferyl alcohol (CA, as a monolignol) and three dilignols and their reaction kinetics were investigated. The dilignols [guaiacylglycerol-β-coniferyl ether (IβO4
), dehydrodiconiferyl alcohol (IIβ5
), and pinoresinol (IIIββ
)] and CA as a monolignol [(3-OCD3)-coniferyl alcohol (CAOCD3
)] were synthesized and subjected to enzymatic DHP formation. The dilignol derived from CAOCD3
could be identified by its higher molecular weight in comparison with the starting dilignols (IβO4
, IIβ5
, and IIIββ
). Based on the observed consumption rate of the CA and its dilignols, it was proposed that a radical transfer system exists between the dilignols, which is generated from the CA and the starting substrates.
The diagnostic challenge of ovarian carcinoma in normal-sized ovaries: a report of two cases

Published: August 2018

Abstract
Normal-sized ovarian carcinoma syndrome (NOCS) is a rare condition characterised by malignancy identified in ovaries of normal size with abdominal metastasis. We report two cases of advanced ovarian carcinoma with ovaries of normal size. The first case was a 13-year-old adolescent with malignant ascites and bilateral normal sized multicystic ovaries detected on ultrasound. Serum cancer antigen 125 (CA 125) and lactate dehydrogenase were markedly raised. A computed tomography (CT) scan showed the presence of thick omental cake but no ovarian tumour. An ultrasound-guided biopsy of the omental cake was undertaken. A histopathological examination and immunohistochemical studies of omentum caking confirmed a diagnosis of high-grade serous carcinoma of ovarian in origin. Despite neoadjuvant chemotherapy, she deteriorated rapidly with acute renal failure and respiratory distress. She succumbed to her disease 10 weeks after diagnosis. The second case, a 69-year-old postmenopausal female presented with malignant ascites and ultrasound evaluation showed hydrometra and bilateral atrophic ovaries. CA 125 was significantly raised. A laparoscopic biopsy of the left ovary and endometrial sampling were performed. A diagnosis of synchronous primary high grade papillary serous ovarian cystadenocarcinoma and endometrial adenocarcinoma were revealed. Relapse occurred despite ongoing adjuvant chemotherapy. We concluded that a preoperative definitive diagnosis of NOCS is difficult. Strong clinical suspicion is needed when all the important causes of malignant ascites are excluded. Radiological-guided biopsy and laparoscopic biopsy are useful to achieve the diagnosis of NOCS.
Induced-Pitting Behaviors of MnS Inclusions in Steel
Authors: Yang Shufeng , Zhao Mengjing , Feng Jie , Li Jingshe , Liu Chengsong 
Published: August 2018

AbstractThis paper investigated the effects of MnS inclusions on inducing pitting in steel. Three different cooling methods were used to control the morphology, size, and distribution of MnS inclusions. AC (alternating current) impedance spectroscopy experiments and potentiodynamic polarization experiments were carried out for different sizes of MnS inclusions. The corrosion immersion experiment was conducted to study the pitting corrosion process in different morphologies of MnS inclusions. The experiment results showed that pitting corrosion occurred around MnS inclusions and pitting was induced along the junction of MnS inclusions and their surrounding steel matrix. Also, the sensitivity of inducing-pitting of MnS inclusions was changed with the change of the average size of MnS in steel and it had a critical size of MnS. The deeper the MnS inclusions were buried in steel matrix, the more difficult it was for it to dissolve and fall off. Herein, it would cause greater damage.
Local inhibition of carbonic anhydrase does not decrease sweat rate
Authors: Moore Jeff , Northway Sarah , Wells Nicole , Woolf Emily , Buono Michael J. 
Published: August 2018

Abstract

Background:
The purpose of this study was to measure sweat rate during exercise in the heat after directly inhibiting carbonic anhydrase (CA) in eccrine sweat glands via transdermal iontophoresis of acetazolamide. It was hypothesized that if CA was important for sweat production, local administration of acetazolamide, without the confounding systemic effects of dehydration typically associated with past studies, would have a significant effect on sweat rate during exercise.

Methods:
Ten healthy subjects volunteered to exercise in the heat following acetazolamide or distilled water iontophoresis on the forearm.

Results:
The distilled water iontophoresis site had a mean sweat rate during exercise in the heat of 0.59±0.31 μL/cm2/min, while the acetazolamide iontophoresis site had a mean sweat rate of 0.63±0.36 μL/cm2/min (p>0.05).

Conclusions:
The most important finding of the current study was that iontophoresis of acetazolamide did not significantly decrease sweat rate during exercise in the heat. Such results suggest that in past studies it was systemic dehydration, and not CA inhibition at the level of the sweat gland, that caused the reported decreased sweat rate.
Effect of caffeine on alcohol consumption and alcohol-induced conditioned place preference in rodents
Authors: Okhuarobo Agbonlahor , Igbe Ighodaro , Yahaya Abdulmajid , Sule Zakariya 
Published: August 2018

Abstract

Background
The aim of the study was to determine the effect of caffeine on alcohol consumption with or without deprivation and alcohol-induced conditioned place preference.

Methods
In the present study, we examined the effects of caffeine (2.5, 5 and 10 mg/kg) on alcohol consumption in Wistar rats with or without periods of deprivation in an unlimited-access, two-bottle, free choice drinking procedure after a stable baseline alcohol consumption was established. Conditioned place preference (CPP) was established by intraperitoneal injections of alcohol (2 g/kg) in a 12-day conditioning schedule in mice. The effect of caffeine (3 mg/kg) on CPP expression was determined by a final post-conditioning test following 12 conditioning sessions with alcohol. The effect of caffeine (3 mg/kg) on the reinstatement of alcohol-induced CPP was determined in a final post-conditioning test following 12 conditioning sessions with alcohol and the extinction of alcohol-induced CPP.

Results
Alcohol deprivation for 3 days did not result in alcohol deprivation effect (ADE). While caffeine (10 mg/kg) caused a significant (p<0.05) reduction in alcohol consumption compared with the baseline following a period of alcohol deprivation, it did not cause a change in alcohol consumption compared with the baseline in the study without alcohol deprivation phase. Caffeine significantly (p<0.05) reduced the expression of alcohol-induced CPP compared to saline and blocked the reinstatement of alcohol-induced CPP following the injection of a priming dose (0.4 g/kg) of alcohol.

Conclusions
Given that caffeine is an adenosine receptor antagonist, our findings suggest a role for adenosine receptors in the alcohol reward and alcohol-seeking behaviour.

Abstract

Aims
Patients with type 2 diabetes mellitus (T2DM) are prone to cardiovascular disease (CVD) due to inflammation process and oxidative stress. ADMA (Asymmetric dimethylarginine) and ICAM-1 (inter-cellular adhesion molecule-1) play an important role in CVD pathogenesis. Ginger as an anti-oxidant and anti-inflammation can effect on these biomarkers. The aim of present study was to characterize the effect of ginger supplementation on ADMA and ICAM-1 serum levels in patients with T2DM.

Methods
The present study is a randomized double-blind clinical trial which is conducted among 45 diabetic patients (nginger=23, nplacebo=22). The participants were randomly divided into two intervention and placebo groups which were received 2 g ginger powder and 2 g wheat flour for 10 weeks, respectively. ADMA and ICAM-1 concentration were measured by ELISA method.

Results
Ginger supplementation decreased ADMA serum levels significantly (P=0.002) and sICAM-1 serum levels marginally (P=0.097) in supplementation group after intervention. No significant difference was observed between placebo and supplementation groups.

Conclusions
Present study was conducted among patients with type 2 diabetes mellitus to investigate the effect of ginger supplementation on ADMA and sICAM-1 levels. There was a significant decrement in ADMA serum concentration and slight reduction in sICAM-1 levels in intervention group. The amount of reduction in both biomarkers was not statistically significant in between-groups comparison.
Modulatory effect of some citrus (Citrus limon, Citrus reticulata, Citrus maxima) peels on monoamine oxidase, phosphodiesterase-5 and angiotensin-1 converting enzyme activities in rat heart homogenate
Authors: Ademosun Ayokunle O. , Adebayo Adeniyi A. , Oboh Ganiyu 
Published: August 2018

Abstract

Background
Citrus peels have been reported useful in folk medicine for the management of cardiovascular diseases, but there is dearth of information on the possible mechanisms for their therapeutic action. The aim of this study was to investigate the effect of methanolic extracts from some citrus [lime (Citrus limon), tangerine (Citrus reticulata), shaddock (Citrus maxima)] peels on some enzymes relevant to the management of cardiovascular diseases [monoamine oxidase (MAO), phosphodiesterase-5 (PDE-5) and angiotensin-1-converting enzyme (ACE)].

Methods
Effect of methanolic extracts of lime, tangerine and shaddock peels on MAO, PDE-5 and ACE were carried out using standard methods. In addition, the ability of the extracts to prevent oxidative damage in rat heart homogenates was also investigated. Finally, the total polyphenol content of extracts was determined.

Results
The results revealed that methanolic extracts of lime, tangerine and shaddock peels inhibited MAO, PDE-5, ACE and pro-oxidants induced lipid peroxidation in rat heart homogenate in a concentration-dependent manner.

Conclusions
Findings in this study revealed citrus peel methanolic extracts as natural inhibitor of enzymes (MAO, PDE-5 and ACE) implicated in cardiovascular diseases. Therefore, citrus peels could help in the management of cardiovascular diseases possibly through inhibition of these enzymes.
Performance Evaluation of Two Dimensional Photonic Crystal Based All Optical AND/OR Logic Gates
Authors: Jayabarathan Jayson K , Subhalakshmi G , Robinson S 
Published: August 2018

Abstract
In this paper, OR and AND logic gate functions are realized in a triangular lattice using two dimensional photonic crystal (2DPC). The proposed design of logic gates are based on the phenomenon of resonance and interference. The OR and AND logic gates are constructed by varying the rod radius and by creating Y-shaped waveguide in the structure. Initially, the OR gate is designed with reference input and without reference input and it’s extended for AND gate. The functional parameters of the logic gates such as response period, bit rate, contrast ratio and field distribution of different logics are investigated through 2D finite difference time domain (FDTD) method. The contrast ratio, response period, bit rate and size of the three input OR gate are 30 dB, 0.52 ps, 1.92 Tbps and 12.6 μm×11 μm, respectively. Similarly, the aforementioned parameters are estimated for two input OR gate, two input AND gate and three input AND gate. The proposed logic gates are highly desirable for integrated optics.
