A Compensation Method for Spiral Error of Pipeline Bending Strain In-Line Inspection
Authors: Liu Shucong , Zheng Dezhi , Dai Mengxi , Chen Pengchao 
Published: October 2018

AbstractThe in-line inspection tool with an inertia measurement unit (IMU tool) is used to measure the centerline coordinate and bending strain for the oil and gas pipeline. In order to prevent the partial wear during inspection, the tool is used to install the supporting wheel at a regular angle to rotate circumferentially. However, the spiral errors are produced during the course of inspection and thus affect the accuracy of centerline and bending strain. To improve the inspection precision and reduce the incidences of spiral error, this article presents a spiral error compensation method not only to improve the inspection precision of centerline mapping, but also to calibrate and compensate for the bending strain of pipeline. The field pull through test was carried out in a section of oil pipeline, and the results showed that the spiral error could practically be eliminated, with the maximum repetition error reducing from 0.17 to 0.06 m, and the precision of pipeline bending strain descending effectively from 0.04 to 0.02 %. The proposed method proved to be effective for improving the inspection accuracy of pipeline displacement and strain inspection.
Modified Prototypes of Rotary Arm–Type Test System Using a Small Ball Probe for Determination of Cooling Characteristics of Quenchants
Authors: Arimoto Kyozo , Shimaoka Mitsuyoshi , Ikuta Fumiaki 
Published: October 2018

Abstract
Performances of quenchants have been enhanced and maintained based on their cooling characteristics as determined by specific test systems. A rotary arm–type test system with a small ball probe has been developed for this purpose by making prototypes. The unique concept, derived mainly from a circular motion of a small ball probe in quenchants, was proposed by Tawara in 1941. The prototypes have been realized by current heating, measuring, and mechatronic techniques. The material used for the probe has changed from nickel alloy to platinum to resolve the discoloration and thermal aging problems on the probe surface. The performance of the prototypes has been verified by systematic tests using specific quenchants under some cooling conditions.

Objective
Increased oxidative stress has been described in patients with Hashimoto’s thyroiditis (HT). The aim of the present study was to investigate whether high oxidative stress is further influenced by obesity and dietary habits in euthyroid women with HT.

Methods
Two hundred eighteen consecutive euthyroid women with HT were studied and separated in two groups; 102 with thyroxine replacement and 114 without. For the evaluation of oxidative stress, total lipid peroxide levels in serum (TOS) were measured and recoded as ‘high TOS’ vs ‘medium/low TOS’. The type of food and consumption frequency were recorded. Two binary variables were considered; normal vs low fruit consumption and daily vs sporadic vegetable consumption.

Results
‘High TOS’ was more frequent in women under thyroxine replacement (31.4% vs 14.7%, OR = 2.7, 95% CI: 1.4–5.2). The prevalence of ‘high TOS’ was higher among overweight/obese women compared to women with normal BMI (30.4% vs 12.5%, OR = 3.1, 95% CI: 1.5–6.4). Low fruit consumption was associated with increased ‘high TOS’ prevalence (30.6% vs 12.9%, OR = 3.0, 95% CI: 1.4–6.2). Sporadic vegetable consumption was associated with increased ‘high TOS’ prevalence compared to daily consumption (29.9% vs 13.5%, OR = 2.7, 95% CI: 1.3–5.7). The examined risk factors were independent and additive in their effect on TOS. At least three risk factors had to be concomitantly present for the likelihood of ‘high TOS’ to be significantly elevated.

Conclusions
Oxidative stress is increased in women with HT under thyroxine replacement. Nevertheless, normal BMI, daily fruit and vegetable consumption, all contribute in maintaining oxidative stress at low levels.

Authors: Wood Charles T. , Linthavong Olivia , Perrin Eliana M. , Leviton Alan , Allred Elizabeth N. , Kuban Karl C.K. , O’Shea T. Michael ,   on behalf of the ELGAN Study Investigators
Published: October 2018

BACKGROUND:
Childhood obesity is a pervasive public health problem with risk factors such as maternal prepregnancy BMI and rapid infant weight gain. Although catch-up weight gain promotes more favorable neurodevelopment among infants born preterm, it is not clear whether faster weight gain early in life, or other correlates of preterm birth, are associated with later obesity in this population.

METHODS:
We used prospective data from the multicenter, observational Extremely Low Gestational Age Newborn Study. Among 1506 eligible individuals in the initial cohort, 1198 were eligible for follow-up at 10 years of age. We examined BMI in 871 children (58% of the cohort; 74% of survivors) and analyzed relationships between antecedents and overweight or obesity at 10 years of age. A time-oriented approach to multinomial multivariable regression enabled us to calculate odds of overweight and obesity associated with pre- and postnatal antecedents.

RESULTS:
Prepregnancy maternal BMI ≥25 and top quartile infant weight gain in the first year were associated with increased risk of both overweight and obesity at 10 years of age. Single marital status was a risk factor for later child obesity and exposure to tobacco smoke was a risk factor for later child overweight.

CONCLUSIONS:
The risk profiles for overweight and obesity at 10 years of age among children born extremely preterm appear to be similar to the risk profiles of overweight and obesity among children born at term.
Egy középület gyors esztétikai és funkcionális avulása
Authors: Kelecsényi Kristóf Zoltán , Gyetvainé Balogh Ágnes 
Published: October 2018

A tanulmány a Budapest, Kossuth Lajos tér 11. szám alatt álló minisztériumi épület építéstörténetének első két évtizedére koncentrálva elemzi azokat az okokat, amelyek oda vezettek, hogy már 1906-ban tervpályázatokat írtak ki az épület teljes külső és belső átalakítására.
Bukovics Gyula (1841–1914) 1884-ben kapta a megbízást, majd elkészítette első tanulmányterveit a korábban nyolc helyen működő Földmívelés-, ipar- és kereskedelemügyi Ministerium egy épületben való elhelyezésére. A szakma már ekkor kifogásolta, hogy tervpályázatot nem írtak ki, de az épület külső megjelenése és funkcionális kialakítása is súlyos kritikákat kapott. Az 1885–1887-ben megvalósult épület fogadtatása során szintén megoszlottak a vélemények. Kifogásolták riasztónak ható méretét és tömbszerűségét, viszonylagos egyszerűségét, ugyanakkor a sötét udvari irodákat is. A telekhatárok mentén két traktus mélységű épületszárnyak udvari oldalán futó – eredetileg nyitott – széles folyosó valóban komoly árnyékoló hatással bírt.
Az átadás éveit követően sok apróbb beruházásra, javításra, átalakításra került sor, melyekkel egyrészt az épület használhatóságát kívánták javítani, másrészt pedig igazodtak a minisztérium személyzetének, ügyosztályainak folyamatos változásaihoz, illetve különféle kapcsolt intézmények ki- és beköltözéséhez. A stílusát tekintve „római olasz renaissance” homlokzatok szerénynek, dísztelennek hatottak az elkészült Országház és Igazságügyi Palota mellett. Ráadásul 1891-ben eltávolításra kerültek a homlokzat egyes málló műkő díszei is. 1906-ra a felújítás már elodázhatatlanná vált, lehetőséget teremtve a homlokzat áttervezésére is, így mind a külső, mind a belső átalakítására külön tervpályázatokat írtak ki.

Published: October 2018

Aim
This study aims to analyze the number Mutans Streptococci (MS) and its protein profile from the saliva of early childhood caries (ECC) and caries-free subjects.

Methods
MS counts were cultured from saliva samples, and the protein profile of MS was determined from ECC and caries-free subjects. The number of colonies were counted, and the protein bands with the molecular weight of 13, 29, 39, 41.3, 74, and 95 kDa were determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis method.

Results
We found that the number of colonies from saliva of ECC patients was higher than those caries-free (22.20 × 106 CFU/ml vs. 19.16 × 106 CFU/ml, p < 0.05). There are higher expression frequencies in protein 29, 39, 41.3, and 74 kDa of MS in ECC than caries-free subjects.

Conclusions
There is the higher number of MS colonies and difference of MS protein profile isolated from saliva among children with ECC and caries-free counterparts.

Authors: Dowling Nicki A. , Ewin Carrie , Youssef George J. , Merkouris Stephanie S. , Suomi Aino , Thomas Shane A. , Jackson Alun C. 
Published: October 2018

Background and aims
Few studies have investigated the association between problem gambling (PG) and violence extending into the family beyond intimate partners. This study aimed to explore the association between PG and family violence (FV) in a population-representative sample. It was hypothesized that: (a) PG would be positively associated with FV, even after adjusting for sociodemographic variables and comorbidities and (b) these relationships would be significantly exacerbated by substance use and psychological distress. A secondary aim was to explore whether gender moderated these relationships.

Methods
Computer-assisted telephone interviews were conducted with a population-representative sample of 4,153 Australian adults.

Results
Moderate-risk (MR)/problem gamblers had a 2.73-fold increase in the odds of experiencing FV victimization (21.3%; 95% CI: 13.1–29.4) relative to non-problem gamblers (9.4%; 95% CI: 8.5–10.4). They also had a 2.56-fold increase in the odds of experiencing FV perpetration (19.7%; 95% CI: 11.8–27.7) relative to non-problem gamblers (9.0%; 95% CI: 8.0–10.0). Low-risk gamblers also had over a twofold increase in the odds of experiencing FV victimization (20.0%; 95% CI: 14.0–26.0) and perpetration (19.3%; 95% CI: 13.5–25.1). These relationships remained robust for low-risk gamblers, but were attenuated for MR/problem gamblers, after adjustment for substance use and psychological distress. MR/problem gamblers had a greater probability of FV victimization, if they reported hazardous alcohol use; and low-risk gamblers had a greater probability of FV perpetration if they were female.

Discussion and conclusion
These findings provide further support for routine screening, highlight the need for prevention and intervention programs, and suggest that reducing alcohol use may be important in these efforts.
Policy, prevention, and regulation for Internet Gaming Disorder
Authors: Kuss Daria J. 
Published: October 2018

In this commentary, I discuss the recent paper by Király et al. (2018), which provides a systematic review of current and potential policies addressing problematic gaming and suggesting current approaches include those (a) limiting video game availability, (b) reducing risk and harm, and (c) supporting gamers. This commentary uses a number of points raised by Király et al. (2018) to address the issue of policy context by discussing (a) the sociocultural environment and (b) the gamer and the game environment to (c) create the case for prevention to reduce risk and harm and to provide support for gamers and their families.
Potential roles of masculine role discrepancy, discrepancy stress, and self-esteem in affecting addictive use of social networking sites among Chinese men: A random population-based study
Authors: Yang Xue , Lau Joseph T. F. , Wang Zixin , Lau Mason C. M. 
Published: October 2018

Background and aims
Masculine role discrepancy (i.e., men perceiving themselves not living up to the ideal manhood and being less masculine than the typical “man”) and related discrepancy stress were associated with some risk behaviors. No study has looked at their relationships with addictive use of social networking sites (SNSs), an emerging potential public health concern. The study constructed a moderated mediation model to test whether masculine role discrepancy would be positively associated with discrepancy stress, which would, in turn, be positively associated with addictive use of SNS, and whether self-esteem would buffer (moderate) the association between masculine role discrepancy and discrepancy stress.

Methods
A random population-based cross-sectional telephone survey interviewed 2,000 Hong Kong male adults in the general population.

Results
Currently unmarried and non-cohabiting, younger, and better educated participants reported higher addictive use of SNS scores than others. Adjusted for these variables, masculine role discrepancy and discrepancy stress were positively associated, and self-esteem was negatively associated with addictive use of SNS scores. Path analysis indicated that masculine role discrepancy was associated with addictive use of SNS through discrepancy stress (mediation); self-esteem buffered (moderated) the association between masculine role discrepancy and discrepancy stress; self-esteem was not significantly associated with addictive use of SNS in this model with good fit.

Discussion
The findings support the general strain theory’s postulation that strain is associated with stress, which is in turn associated with addictive use of SNS sites. Implications, potential interventions, and future studies are discussed in this study.
Spanish validation of the Problem Gambling Severity Index: A confirmatory factor analysis with sports bettors
Authors: Lopez-Gonzalez Hibai , Estévez Ana , Griffiths Mark D. 
Published: October 2018

Background and aims
The Problem Gambling Severity Index (PGSI) is one of the most widely used screening tools for problem gambling (PG). However, to date, no empirically validated adaptation of the instrument to Spanish-speaking countries exists.

Methods
A sample of 659 sports bettors (Mage = 35.1 years, SD = 10.12, 74.2% males) were recruited through an online research panel. A confirmatory factor analysis (CFA) was performed to confirm its construct validity. The participants were administered the Spanish version of the PGSI, along with the adaptation to Spanish of the DSM-IV PG instrument for convergent validity.

Results
The CFA of the Spanish PGSI showed satisfactory construct validity. The internal consistency (αordinal = .97) as well as its convergent validity with the DSM-IV scores (r = .77, p < .001) was good.

Conclusion
The Spanish adaptation of the PGSI offers satisfactory validity and reliability properties, and is a good psychometric instrument for exploring the social consequences of PG in Spanish-speaking contexts.
Psychometric evaluation of the Persian Internet Disorder Scale among adolescents
Authors: Lin Chung-Ying , Ganji Maryam , Pontes Halley M. , Imani Vida , Broström Anders , Griffiths Mark D. , Pakpour Amir H. 
Published: October 2018

Background and aims
Given the growing epidemiological research interest concerning Internet addiction, brief instruments with a robust theoretical basis are warranted. The Internet Disorder Scale (IDS-15) is one such instrument that can be used to quickly assess the Internet addiction in an individual. However, only two language versions of the IDS-15 have been developed. This study translated the IDS-15 into Persian and examined its psychometric properties using comprehensive psychometric testing.

Methods
After ensuring the linguistic validity of the Persian IDS-15, 1,272 adolescents (mean age = 15.53 years; 728 males) completed the IDS-15, Depression Anxiety Stress Scale (DASS), Internet Gaming Disorder Scale – Short Form (IGDS9-SF), and the Bergen Social Media Addiction Scale (BSMAS). Confirmatory factor analysis (CFA), Rasch models, regression analysis, and latent profile analysis (LPA) were carried out to test the psychometric properties of the Persian IDS-15.

Results
Both CFA and Rasch supported the construct validity of the Persian IDS-15. Multigroup analysis in CFA and differential item functioning in Rasch indicated that male and female adolescents interpreted the IDS-15 items similarly. Regression analysis showed that the IDS-15 correlated with IGDS9-SF and BSMAS (ΔR2 = .12 and .36, respectively) is stronger than the DASS (ΔR2 = .03–.05). LPA based on IDS-15 suggests three subgroups for the sample. Significant differences in depression, anxiety, IGDS9-SF, and BSMAS were found among the three LPA subgroups.

Conclusion
The Persian IDS-15 has robust psychometric properties as evidenced by both classical test theory and Rasch analysis.
Maladaptive daydreaming as a new form of behavioral addiction
Authors: Pietkiewicz Igor J. , Nęcki Szymon , Bańbura Anna , Tomalski Radosław 
Published: October 2018

Background and aims
Maladaptive daydreaming (MD) has many features of behavioral addiction, but research exploring this syndrome is limited. This case study provides a qualitative exploration of MD.

Methods
A structured clinical interview and mental state examination of a patient with MD were video-recorded and transcribed verbatim. Transcripts were subjected to the interpretative phenomenological analysis.

Results
MD was developed as a strategy to cope with distress but led to uncontrollable absorption in fantasy, social withdrawal, and neglecting aspects of everyday life. It was coupled with excessive Internet use and viewing porn.

Discussion and conclusions
Patients should be questioned about MD during clinical assessment. Further studies are necessary to determine whether MD constitutes a separate syndrome or is a part of other behavioral addictions.
The modulation of ureteral smooth muscle contractile responses by α1- and α2-adrenoceptor activation
Authors: Monks DR , Bund SJ 
Published: October 2018

Purpose
This study was performed to investigate the influence of α-adrenoceptor subtypes upon ureteral smooth muscle contractile responses.

Methods
Rat ureters were challenged in vitro with noradrenaline (NA), the α1-adrenoceptor agonist phenylephrine (PE), and the α2-adrenoceptor agonist clonidine (CLON). The influences of the agonists on the magnitude and frequency of acetylcholine (ACh)-stimulated phasic contractile responses were recorded.

Results
The magnitude of the phasic contractile responses effected by ACh was not significantly influenced by the adrenoceptor agonists, but the frequency of the response was significantly enhanced by all three agonists (p < 0.05). Idazoxan and prazosin abolished the rise in frequency effected by CLON and PE, respectively, whereas both antagonists in combination were required to abolish the increase in frequency effected by NA.

Conclusions
It has been demonstrated that α1- and α2-adrenoceptors modulate the contractile function of rat ureteral smooth muscle by increasing the frequency, but not the magnitude, of phasic contractile responses. The enhancement of contractile function by NA is mediated by mechanisms dependent upon both α1- and α2-adrenoceptors.
Protective effects of quercetin from oxidative/nitrosative stress under intermittent hypobaric hypoxia exposure in the rat’s heart
Authors: Chiş IC , Baltaru D , Dumitrovici A , Coseriu A , Radu BC , Moldovan R , Mureşan A 
Published: October 2018

Background
Exposure to high altitude in hypobaric hypoxia (HH) is considered to be a physiological oxidative/nitrosative stress. Quercetin (Que) is an effective antioxidant and free radical scavenger against oxidative/nitrosative stress.

Aims
The aim of this study was to investigate the cardioprotective effects of Que in animals exposed to intermittent HH (IHH) and therefore exposed to oxidative/nitrosative stress.

Materials and methods
Wistar albino male rats were exposed to short-term (2 days) or long-term (4 weeks; 5 days/week) IHH in a hypobaric chamber (5,500 m, 8 h/day, 380 mmHg, 12% O2, and 88% N2). Half of the animals received natural antioxidant Que (body weight: 30 mg/kg) daily before each IHH exposure and the remaining rats received vehicle (carboxymethylcellulose solution). Control rats were kept under normobaric normoxia (Nx) and treated in a corresponding manner. One day after the last exposure to IHH, we measured the cardiac hypoxia-induced oxidative/nitrosative stress biomarkers: the malondialdehyde (MDA) level and protein carbonyl (PC) content, the activity of some antioxidant enzymes [superoxide dismutase (SOD) and catalase (CAT)], the nitrite plus nitrate (NOx) production, and the inducible nitric oxide synthase (iNOS) protein expression.

Results
Heart tissue MDA and PC levels, NOx level, and iNOS expression of IHH-exposed rats had increased, and SOD and CAT activities had decreased compared with those of the Nx-exposed rats (control groups). MDA, CP, NOx, and iNOS levels had decreased in Que-treated IHH-exposed rats compared with IHH-exposed rats (control groups). However, Que administration increased SOD and CAT activities of the heart tissue in the IHH-exposed rats.

Conclusion
HH exposure increases oxidative/nitrosative stress in heart tissue and Que is an effective cardioprotective agent, which further supports the oxidative cardiac dysfunction induced by hypoxia.

Published: October 2018

Purpose
The authors intended to develop a novel procedure and research method that follows the effectiveness of the peer-educational approach in handwashing among school children.

Materials and methods
To ask the children about their sociodemographic background, health behaviour, hand hygiene knowledge, and health attitudes, and questionnaires were applied. The education on proper handwashing procedures was followed by a test with a mobile UV-light detection system (Semmelweis Scanner, http://www.handinscan.com/), and the scans were evaluated through an intrinsic computer software.

Results
Our newly developed questionnaire-based research method and the hand-rubbing technique followed by a test with a mobile UV-light detection system may become a reliable and valid scientific measurement of the effectiveness of hand hygiene training programmes.

Conclusions
The Hand-in-Scan technology and questionnaire-based research method provide proper tools for evaluating the successful peer education method. It can significantly elevate the level of children’s compliance, which leads to a better hygienic consciousness.
