Effect Of Polyetheretherketone (PEEK) As Denture Base Material On Peri-Implant Bone Level Changes In Implant Bar Retained Overdenture Using CAD/CAM Technology

Objectives: This research was carried out to evaluate the effect of Polyetheretherketone (PEEK) as denture base material on peri-implant crestal bone level changes in edentulous patients rehabilitated with implant-supported primary-secondary bar overdenture and retained attachments attached the body of the bar constructed by CAD / CAM technology. Materials and Methods: Twenty completely edentulous patients complaining from insufficient retention of their mandibular denture were selected to participate in this study. All the patients were rehabilitated with an implant-supported bar overdenture. For All patients three implants (3.7mm) in diameter (11mm) in length were inserted in the interforamenal region using computer guided surgical template. Four months later, Cast bar with two semi precession attachment at the distal ends of the bar was constructed, The cast bar was scanned using bench laser scanner to obtain virtual model with the bar, the housing on the top of the bar and the female part of the attachment was designed using computer aided designing (CAD) the meld into wax by computer aided manufacturing (CAM). The CAD/ CAM wax pattern of housing and the female part of the attachments were transferred into acetal resin using the injection molded technique. Overdentures were constructed for all patients following the conventional technique. According to the denture base material, a toss coin was made to randomly divided the patients into two equal groups; group I received mandibular implant-retained overdenture were processed using heat cured acrylic resin, following the long curing cycle (heated at 78C° for eight hours), while for group II Polyetheretherketone (PEEK) lower overdenture was constructed, using the injection-molding technique. Radiographic evaluation of peri-implant bony changes was made using standardized long cone paralleling technique with custom made acrylic template and the Rinn-xcp at insertion, six, twelve and twenty four months were measured and statistically analyzed. The significant level was set at P ≤ 0.05P . ANOVA for repeated measures test was used to compare between follow up periods within groups and when statistically significant it was followed by simple main effect analysis with Bonferioni correction. One way ANOVA test was used to compare between groups at different follow up periods. Results. Both groups showed a statistically insignificant increase loss in crestal bone height around the implants. Although the data obtained from table1 revealed increase in the amount of bone changes for group I and Group II compared to group I during the follow up period statistical analysis of the data using ANOVA test for repeated measures revealed no significance difference(P ≥ 0.05) .Conclusion: CAD/ CAM technology and use of Polyetheretherketone (PEEK) as denture base material should be considered whenever possible to preserve the implant supporting structures in implant bar retained overdenture.

Age-related changes in proprioception of the ankle complex across the lifespan

BackgroundAnkle complex proprioceptive ability, needed in active human movement, may change from childhood to elderly adulthood; however, its development across all life stages has remained unexamined. The aim of the present study was to investigate the across-the-lifespan trend for proprioceptive ability of the ankle complex during active ankle inversion movement. MethodsThe right ankles of 118 healthy right-handed participants in 6 groups were assessed: children (6–8 years old), adolescents (13–15 years old), young adults (18–25 years old), middle-aged adults (35–50 years old), old adults (60–74 years old), and very old adults (75–90 years old). While the participants were standing, their ankle complex proprioception was measured using the Active Movement Extent Discrimination Apparatus. ResultsThere was no significant interaction between the effects of age group and gender on ankle proprioceptive acuity (F (5, 106) = 0.593, p = 0.705, η2p = 0.027). Simple main effects analysis showed that there was a significant main effect for age group (F (5, 106) = 22.521, p < 0.001, η2p = 0.515) but no significant main effect for gender (F (1,106) = 2.283, p = 0.134, η2p = 0.021) between the female (0.723 ± 0.092, mean ± SD) and the male (0.712 ± 0.083) participants. The age-group factor was associated with a significant linear downward trend in scores (F (1, 106) = 10.584, p = 0.002, η2p = 0.091) and a strong quadratic trend component (F (1,106) = 100.701, p < 0.001, η2p = 0.480), producing an asymmetric inverted-U function. ConclusionThe test method of the Active Movement Extent Discrimination Apparatus is sensitive to age differences in ankle complex proprioception. For proprioception of the ankle complex, young adults had significantly better scores than children, adolescents, old adults, and very old adults. The middle-aged group had levels of ankle proprioceptive acuity similar to those of the young adults. The scores for males and females were not significantly different. Examination of the range of the scores in each age group highlights the possible level that ankle complex movement proprioceptive rehabilitation can reach, especially for those 75–90 years of age.

Post-Concussion Symptom Factors in Male and Female High School and Collegiate Athletes

Previous research suggests concussed female athletes report higher severity of total symptoms; however, sex differences for symptom factors across recovery are understudied. PURPOSE: To examine sex differences in post-concussion symptom factors across concussion recovery (i.e., ≤72 hours, return-to-play, >one-month). METHODS: Symptoms were rated from 0 (none) to 6 (severe) on the Post-Concussion Symptom Scale (PCSS), which consists of 22 total symptoms and a total symptom severity score ranging from 0-132. The PCSS was broken into two symptom factors: cognitive-migraine-fatigue (headache, dizziness, fatigue, drowsiness, sensitivity to light/noise, feeling slowed down, fogginess, difficulty concentrating/remembering) and affective (sadness, nervousness, feeling more emotional). A 2 sex (male, female)*2 group (concussed, healthy)*3 time (≤72 hours, return-to-play, >one-month) repeated measures ANOVA was used to analyze sex differences in symptom factors throughout recovery between concussed and healthy athletes. RESULTS: There were 167 (M=17.46 years, SD=2.2; male=97, female=70; concussed=78, healthy=89) total athletes. There were no significant sex differences between testing sessions at ≤72 hours (M=2.03 days, SD=0.8, p=.42), return-to-play (M=16.09 days, SD=11.7, p=.95), and >one-month (M=59.72 days, SD=21.4, p=.65). There was no significant within-subject interaction for sex*group*time for the cognitive-migraine-fatigue or affective symptom factors. There was a significant between-subjects sex*group interaction for the cognitive-migraine-fatigue symptom factor (F(1,163)=5.52, p=.02, η2=.03). Simple main effects analysis revealed concussed females (M=7.39, SE=0.57) reported significantly higher severity for the cognitive-migraine-fatigue symptom factor than concussed males (M=4.83, SE=0.48; p≤.001), yet no sex differences were observed between healthy athletes (p=.82). There was no significant between-subjects sex*group interaction for the affective post-concussion symptom factor. CONCLUSIONS: Concussed females reported greater symptom severity for the cognitive-migraine-fatigue symptom factor compared to concussed males, which may direct targeted concussion management approaches between female and male athletes.

3207 Relation between Dopamine Transporter (DAT1) polymorphism and subjective effects of alcohol among non-dependent drinkers

OBJECTIVES/SPECIFIC AIMS: Dopamine transporter (DAT1) gene variation is associated with reward-related phenotypes including alcohol response. There is also evidence for a potential moderating role for mu-opioid receptor (OPRM1) gene variation on the relationship between DAT1 variation and alcohol response measures. We aimed at studying the interaction between the DAT1 VNTR and OPRM1 A118G polymorphisms on alcohol consumption and subjective responses among non-dependent drinkers. METHODS/STUDY POPULATION: We employed a progressive ratio (PR) paradigm of intravenous alcohol self-administration (IV-ASA) using the Computer-Assisted Infusion System (CAIS) to assess the motivation for alcohol seeking and consumption in a sample of nondependent drinkers. We used the Drug Effects Questionnaire (DEQ) and Biphasic Alcohol Effects Questionnaire (BAES) to assess subjective response. IV-ASA measures included average breath alcohol concentration (BrAC) and total ethanol infused. Peripheral blood samples were collected for genotyping. Ethics approval was obtained from the NIH Addictions Institutional Review Board. RESULTS/ANTICIPATED RESULTS: Fifty participants completed the PR IV-ASA session after informed consent. There were significant interactions between the DAT1 and OPRM1 genotypes in subjective effects of alcohol. Simple main effects analysis showed that DAT1 10a allele carriers that were also OPRM1 G allele carriers had significantly higher scores for several measures: “feel the drug effects” (F (1,46)=6.573, P = 0.014), “feel intoxicated”(F(1,46)=8.613, P = 0.005) and “feeling high” (F(1,46)=10.889, P = 0.002) in DEQ and higher sedation (F(1,46)=4.575, P = 0.038) in BAES. The genotypes statistically significantly predicted average breath alcohol (F (1,61) =3.295, p=0.044) and total ethanol infused(F(1,61)=3.632, p=0.032. DAT1 VNTR and OPRM1 A118G polymorphisms taken together accounted for 6.9 and 7.8% of variations in average breath alcohol and total ethanol infused respectively. DISCUSSION/SIGNIFICANCE OF IMPACT: Polymorphic variations in DAT1 and OPRM1 interact with each other in determining subjective effects of alcohol in intravenous alcohol infusion assessing motivation for alcohol seeking and consumption in nondependent drinkers. These epistatic interactions in subjective effects of alcohol are salient in the context of predicting and understanding neurobiological effects of alcohol and thereby the therapeutic responses in treating alcohol use disorders.

A functional promoter variant of the human formimidoyltransferase cyclodeaminase (FTCD) gene is associated with working memory performance in young but not older adults.

The central role of working memory in IQ and the high heritability of working memory performance motivated interest in identifying the specific genes underlying this heritability. The FTCD (formimidoyltransferase cyclodeaminase) gene was identified as a candidate gene for allelic association with working memory in part from genetic mapping studies of mouse Morris water maze performance. The present study tested variants of this gene for effects on a delayed match-to-sample task of a large sample of younger and older participants. The rs914246 variant, but not the rs914245 variant, of the FTCD gene modulated accuracy in the task for younger, but not older, people under high working memory load. The interaction of haplotype × distance × load had a partial eta squared effect size of 0.015. Analysis of simple main effects had partial eta squared effect sizes ranging from 0.012 to 0.040. A reporter gene assay revealed that the C allele of the rs914246 genotype is functional and a main factor regulating FTCD gene expression. This study extends previous work on the genetics of working memory by revealing that a gene in the glutamatergic pathway modulates working memory in young people but not in older people.

Cardiorespiratory fitness attenuates age-associated aggregation of white matter hyperintensities in an at-risk cohort

BackgroundAge is the cardinal risk factor for Alzheimer’s disease (AD), and white matter hyperintensities (WMH), which are more prevalent with increasing age, may contribute to AD. Higher cardiorespiratory fitness (CRF) has been shown to be associated with cognitive health and decreased burden of AD-related brain alterations in older adults. Accordingly, the aim of this study was to determine whether CRF attenuates age-related accumulation of WMH in middle-aged adults at risk for AD.MethodsOne hundred and seven cognitively unimpaired, late-middle-aged adults from the Wisconsin Registry for Alzheimer’s Prevention underwent 3 T magnetic resonance imaging and performed graded maximal treadmill exercise testing from which we calculated the oxygen uptake efficiency slope (OUES) as our measure of CRF. Total WMH were quantified using the Lesion Segmentation Tool and scaled to intracranial volume. Linear regression adjusted for APOE4 carriage, family history, body mass index, systolic blood pressure, and sex was used to examine relationships between age, WMH, and CRF.ResultsAs expected, there was a significant association between age and WMH (p < .001). Importantly, there was a significant interaction between age and OUES on WMH (p = .015). Simple main effects analyses revealed that the effect of age on WMH remained significant in the Low OUES group (p < .001) but not in the High OUES group (p = .540), indicating that higher CRF attenuates the deleterious age association with WMH.ConclusionsHigher CRF tempers the adverse effect of age on WMH. This suggests a potential pathway through which increased aerobic fitness facilitates healthy brain aging, especially among individuals at risk for AD.

Association between N-methyl-d-aspartate Receptor Subunit 2B Gene Polymorphisms and Personality Traits in a Young Japanese Population

The N-methyl-D-aspartate receptor subunit 2B (GluN2B) is involved in regulation of anxiety and depression and nervous activity in the brain. Single nucleotide polymorphisms of the GluN2B gene (GRIN2B) are associated with human mental function and behaviour. We investigated whether four GRIN2B polymorphisms (rs7301328, rs1806201, rs1805247, and rs1805502) affect characterisation of personality traits. In 248 young people, GRIN2B polymorphisms were analysed, and personality traits were assessed using the Neuroticism Extraversion Openness-Five Factor Inventory (NEO-FFI) and State-Trait Anxiety Inventory (STAI). There was no main effect of the GRIN2B polymorphisms on the NEO-FFI and STAI dimension scores. Interaction between polymorphism and sex was found in rs1805247 (p = 0.034) and rs1805502 (p = 0.040) in terms of the conscientiousness score of the NEO-FFI. However, post hoc simple main effect analysis showed no significant effect. The preliminary haplotype analysis indicated that haplotype CTT (rs1806201-rs1805247-rs1805502) in the haplotype block was associated with the extraversion score of the NEO-FFI in female participants (p = 0.044), but the significance was lost on correction for multiple testing. There was no significant association between selected GRIN2B polymorphisms and personality traits, but this may be due to low statistical power. Further studies involving a larger study population are needed to clarify this.

A STUDY ON THE EFFECT OF NOISE AND VIBRATION ON OPERATORS’ READABILITY TASK PERFORMANCE IN A MOBILE DRIVING ENVIRONMENT

This paper presents a study in which the effect of noise and vibration on the task performance in a mobile driving environment is experimentally investigated. A readability kind of task, where a reading material was presented to the operators on a laptop screen was considered and the operators performed the task in a sitting posture without their back supported with the backrest of the seat. The task performance was measured in terms of mean number of characters read per minute by the operators, which served as data for statistical analysis. Results of the study showed that noise and vibration were statistically significant. The interaction between gender and vibration was also found to be significant. The presence of noise and vibration in a mobile environment decreased the operators’ task performance. The results of the simple main effect analysis indicated that the gender was statistically significant for the last two levels of vibration. However the equivalent acceleration of vibration was found statistically significant for males and females. The findings are in line with previous researches that showed negative significant effect of noise and vibration on operators’ task performance.

Treatment resistant schizophrenia and neurological soft signs may converge on the same pathology: Evidence from explanatory analysis on clinical, psychopathological, and cognitive variables

Here, we investigated neurological soft signs (NSSs) in treatment resistant schizophrenia (TRS) vs treatment responder schizophrenia (SZ) patients. TRS is a severe condition, affecting approximately one-third of schizophrenia patients and representing a relevant clinical challenge. NSSs are neurological abnormalities reportedly described in schizophrenia patients and linked to dysregulated network connections. We explored the possibility that NSSs may be: i) more severe in TRS patients; ii) differentially associated to clinical/cognitive variables in TRS vs SZ; iii) predictive of having TRS. In addition, we evaluated whether diagnosis may mediate NSSs associations with the above-mentioned variables. Consecutive patients with schizophrenia diagnosis underwent stringent assessment for TRS diagnosis. Demographics and clinical variables were recorded. Psychopathology (by Positive and Negative Syndrome Scale, PANSS), cognitive performances, and NSSs (by Neurological Evaluation Scale, NES) were tested.TRS had higher scores than SZ patients in total NES score and in almost all NES subscales, even after correction for duration of illness and antipsychotic dose (ANCOVA, p<0.05). NSSs significantly correlated with multiple clinical, psychopathological, and cognitive variables (above all: duration of disease and negative symptoms) in TRS but not in SZ patients. Two-way ANOVA showed NSS-x-diagnosis interaction in determining outcomes on multiple cognitive performances, but not in other clinical variables. However, simple main effect analysis detected a significant relationship between high severity NSSs and TRS diagnosis on multiple clinical and cognitive outcomes. Hierarchical regression analysis showed that diagnosis was among a discrete number of predictors yielding significant increases in variance explained on NES total, Sensory Integration and Other Signs subscales' scores. NSSs, together with antipsychotic dose and disease severity, were found to be significantly predictive of TRS diagnosis in a binary logistic regression model. These results suggest a stringent association between NSSs and TRS diagnosis, and may imply that NSSs association with clinical, psychopathological, and cognitive variables may be in part mediated by TRS diagnosis.

A Study on the Effect of Social Commerce Beauty Product Type, Discount Rate and Regulatory Focus on Purchase Intention

This study intended to verify the interaction of social commerce beauty product types, discount rates, and regulatory focuses on purchasing intention. The design consisted of three-way mixed design of 2 (social commerce beauty product type: general product, service product) x 2 (discount rate: high, low) x 2 (regulatory focus: improvement focus, prevention focus). This study was conducted with 280 women over 20 years old who have used social commerce in Seoul and the Gyeonggi region, and a total of 259 copies were used for the final analysis excluding the data with incomplete responses. Frequency analysis, credibility analysis, three-way ANOVA, simple interaction effect analysis, and simple main effect analysis were conducted using the SPSS 18.0 Statistical Package for data analysis. The results of this study were as follows. First, it was identified that the social commerce beauty product type and discount rate have a significant effect on purchase intention. Consumers of beauty products through social commerce prefer intangible beauty service products than general products that they can also purchase in other sites and prefer products with a higher discount rate. Secondly, it was identified that the social commerce beauty products type, discount rate, and regulatory focus make significant interaction effect on purchase intention. The preventive focus group that tried to manage risk and use several alternatives or previous alternatives repeatedly showed higher purchase intention when the discount rate of beauty service products was higher. The result implies that consumers who have used social commerce feel less risk regarding quality because they have direct and indirect experience with social commerce products. Therefore, companies who wish to sell beauty products in social commerce should establish different marketing strategies depending on consumer experiences with social commerce.

Influence of abutment tooth geometry on the accuracy of conventional and digital methods of obtaining dental impressions

Statement of problemDirect (intraoral) and indirect (desktop) digital scanning can record abutment tooth preparations despite their geometry. However, little peer-reviewed information is available regarding the influence of abutment tooth geometry on the accuracy of digital methods of obtaining dental impressions. PurposeThe purpose of this in vitro study was to evaluate the influence of abutment tooth geometry on the accuracy of conventional and digital methods of obtaining dental impressions in terms of trueness and precision. Material and methodsCrown preparations with known total occlusal convergence (TOC) angles (−8, −6, −4, 0, 4, 8, 12, 16, and 22 degrees) were digitally created from a maxillary left central incisor and printed in acrylic resin. Each of these 9 reference models was scanned with a highly accurate reference scanner and saved in standard tessellation language (STL) format. Then, 5 conventional polyvinyl siloxane (PVS) impressions were made from each reference model, which was poured with Type IV dental stone scanned using both the reference scanner (group PVS) and the desktop scanner and exported as STL files. Additionally, direct digital impressions (intraoral group) of the reference models were made, and the STL files were exported. The STL files from the impressions obtained were compared with the original geometry of the reference model (trueness) and within each test group (precision). Data were analyzed using 2-way ANOVA with the post hoc least significant difference test (α=.05). ResultsOverall trueness values were 19.1 μm (intraoral scanner group), 23.5 μm (desktop group), and 26.2 μm (PVS group), whereas overall precision values were 11.9 μm (intraoral), 18.0 μm (PVS), and 20.7 μm (desktop). Simple main effects analysis showed that impressions made with the intraoral scanner were significantly more accurate than those of the PVS and desktop groups when the TOC angle was less than 8 degrees (P<.05). Also, a statistically significant interaction was found between the effects of the type of impression and the TOC angle on the precision of single-tooth dental impressions (F=2.43, P=.002). Visual analysis revealed that the intraoral scanner group showed a homogeneous deviation pattern across all TOC angles tested, whereas scans from the PVS and desktop scanner groups showed marked local deviations when undercuts (negative angles) were present. ConclusionsConventional dental impressions alone or those further digitized with an extraoral digital scanner cannot reliably reproduce abutment tooth preparations when the TOC angle is close to 0 degrees. In contrast, digital impressions made with intraoral scanning can accurately record abutment tooth preparations independently of their geometry.

할인점 PB패션제품의 제품유형, POP 메시지 프레이밍, 인지종결욕구가 소비자의 호의도에 미치는 영향

This study intended to empirically verify the effect of message framing, cognitive need for closure, and type of fashion products on purchasing attitude of PB fashion products in discount stores. The design consisted of three-mixed design of 2(POP(Point of Purchase)message framing: benefit message vs. loss message) <TEX>${\times}2$</TEX>(cognitive need for closure: high vs. low) <TEX>${\times}2$</TEX>(PB fashion product type: utilitarian vs. hedonic). Survey of this study was conducted on 330 men and women in 20~50's in Seoul and Gyeong-gi, and a total of 287 data were analyzed. Data were analyzed with SPSS 18.0 program, and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First, it was identified that the framing type of POP message of discount store, cognitive need for closure, and PB fashion product type had significant effect on preference and purchase intention. Secondly, it was identified that consumers with both high and low cognitive need for closure had high preference level and purchase intention when they encountered the benefit message framing than the loss message framing. Thirdly, the benefit message framing was more effective than the loss message framing for hedonic PB fashion products in discount stores, but utilitarian PB fashion products did not get affected by the message framing. Fourthly, it was identified that groups with both high and low cognitive need for closure preferred hedonic PB fashion products. Lastly, it was verified that benefit message framing POP advertisement on a group with high cognitive need for closure was effective for Hedonic PB fashion products in discount stores, and utilitarian PB fashion products showed no difference in purchase intention according to the POP message framing type and cognitive need for closure.

A 9-year follow-up of a self-management group intervention for persistent neck pain in primary health care: a randomized controlled trial.

Background and objectiveIn previous short-term and 2-year follow-ups, a pain and stress self-management group intervention (PASS) had better effect on pain-related disability, self-efficacy, catastrophizing, and perceived pain control than individually administered physiotherapy (IAPT) for patients with persistent tension-type neck pain. Studies that have evaluated long-term effects of self-management approaches toward persistent neck pain are sparse. The objective of this study was to compare pain-related disability, self-efficacy for activities of daily living (ADL), catastrophizing, pain, pain control, use of analgesics, and health care utilization in people with persistent tension-type neck pain 9 years after they received the PASS or IAPT.Materials and methodsOf 156 people (PASS, n = 77; IAPT, n = 79) originally included in a randomized controlled trial, 129 people (PASS, n = 63; IAPT, n = 66) were eligible and were approached for the 9-year follow-up. They were sent a self-assessment questionnaire, comprising the Neck Disability Index, the Self-Efficacy Scale, the Coping Strategies Questionnaire, and questions regarding pain, analgesics, and health care utilization. Mixed linear models for repeated measures analysis or generalized estimating equations were used to evaluate the differences between groups and within groups over time (baseline, previous follow-ups, and 9-year follow-up) and the interaction effect of “time by group”.ResultsNinety-four participants (73%) responded (PASS, n = 48; IAPT, n = 46). At 9 years, PASS participants reported less pain-related disability, pain at worst, and analgesics usage, and a trend toward better self-efficacy compared to IAPT participants. There was a difference between groups in terms of change over time for disability, self-efficacy for ADL, catastrophizing, perceived pain control, and health care visits in favor of PASS. Analyses of simple main effects at 9 years showed that the PASS group had less disability (p = 0.006) and a trend toward better self-efficacy (p = 0.059) than the IAPT group.ConclusionThe favorable effects on pain-related disability of PASS were sustained 9 years after the intervention.

Is Alcohol Consumption Associated with Job Strain Among Professional Musicians?

To assess the strength of the relationship between alcohol consumption and job strain experienced by professional musicians. Cross-sectional survey among professional orchestra musicians (n=1,550, response rate 41%, data available for 590 respondents). The difference between groups with and without job strain was assessed by two-way analysis of variance. The median alcohol consumption was 48 g/wk (range 1-648, IQR 12-96). There were only 25 (4%) heavy drinkers, defined as people who consume >210 g of pure alcohol a week. The average frequency of drinking was 2.1 times/wk (SD 2.0, range 0-7). Of the respondents, 125 (21%) reported an elevated level of job strain as defined by the responses to Job Content Questionnaire. There was no significant interaction between the effects of gender and job strain on alcohol consumption: F(1, 586) = 0.82, p=0.365. Simple main effects analysis showed that males were consuming alcohol significantly more than females were (p=0.0005), but there were no differences between participants with elevated level of job strain compared with the rest of the sample (p=0.546). The amount of alcohol consumed was not associated with the presence or absence of perceived occupational strain among professional orchestra musicians.

Effect of elbow flection on grip strength in vertical and horizontal directions.

In this study the effect of elbow flexion with forward flexion of the upper arm and shoulder rotation on the maximum voluntary contraction (MVC) of grip strength was investigated. Two directions (vertical and horizontal), three positions (left side, central and right) and five elbow flexion angles were taken as independent variables. The analysis of variances (ANOVA) was performed on the data collected. The results of the analysis showed that there was highly significant effect of the direction, front position of the wrist (the line in front of the right shoulder, centre of the chest and left shoulder using the right hand in the sagittal plane), and the elbow flexion angle on MVC grip strength. The left position has significantly low grip strength compared to the right position for right-hand participants. The two-way interactions of all the three main factors were found significant. The three-way interaction was not found significant. Further one-way ANOVAs showed that the effect of the direction (vertical/horizontal) was not found significant on any of the levels of the position and elbow flexion in the simple main effects analysis (p > 0.05).

Art Infusion Effect on Fashion Products according to Self-monitoring and the Luxury Level of Fashion Brands

This study empirically confirmed how an art infusion into fashion products affect consumer`s preference through Study 1 and Study 2. Study 1 examined the effect of an art infusion and the difference of an art infusion effect according to self-monitoring scale by designing groups composed of 2 (art infusion: infusion versus non-infusion) (self-monitoring: high versus low). Study 2 examined the difference of an art infusion effect according to the luxury level of fashion brands by designing groups composed of 2 (art infusion: infused versus non-infused) (fashion brand luxury levels: high versus mid versus low). This study was conducted using a convenience sample of women in their 20s and 30s residing in the Seoul and Daegu region. In Study 1, 162 participants were randomly assigned to two experiment situations of art infusion. In Study 2, 192 participants were randomly assigned to six experiment situations of art infusion and luxury level of fashion brands. For the data analysis, we conducted reliability analysis, two-way ANOVA and simple main effect analysis using SPSS 18.0 statistics package. The results of Study 1 and 2 are as follows. First, consumer`s preference was shown to be higher for fashion products with art infusion rather than fashion products without art infusion. Second, the positive effect of art infusion on consumer`s preference was significant in the group of high selfmonitors. But there was a non-significant effect of art infusion in the group of low self-monitors. Lastly, the positive effect of art infusion on consumer`s preference is higher in the case of a mid-level luxury brand rather than in the case of a high-level luxury brand and low-level luxury brand.

Engineering-Driven Statistical Adjustment and Calibration

Engineering model development involves several simplifying assumptions for the purpose of mathematical tractability, which are often not realistic in practice. This leads to discrepancies in the model predictions. A commonly used statistical approach to overcome this problem is to build a statistical model for the discrepancies between the engineering model and observed data. In contrast, an engineering approach would be to find the causes of discrepancy and fix the engineering model using first principles. However, the engineering approach is time consuming, whereas the statistical approach is fast. The drawback of the statistical approach is that it treats the engineering model as a black box and therefore, the statistically adjusted models lack physical interpretability. This article proposes a new framework for model calibration and statistical adjustment. It tries to open up the black box using simple main effects analysis and graphical plots and introduces statistical models inside the engineering model. This approach leads to simpler adjustment models that are physically more interpretable. The approach is illustrated using a model for predicting the cutting forces in a laser-assisted mechanical micro-machining process. This article has supplementary material online.

패션브랜드 확장 유형, 프리어나운싱, 조절초점이 확장제품의 호의도에 미치는 영향

This study aimed to identify the effects of fashion brand extensions types, preannouncing and consumers`` regulatory focus on preference towards extension products. To that end, the study used a 2 (fashion brand extension types: similar vs. non-similar) × 2 (preannouncing: near preannouncing vs. far preannouncing) × 2 (regulatory focus: promotion focus vs. prevention focus) three mixed elements. The subjects of the study were 280 men and women in their 20~40s living in Seoul and Chungnam province and total of 229 data were analyzed. Data were analysed with SPSS 19.0 program and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First there were significant differences in preference based on fashion brand extension types and preannouncing. Second, there were significant interaction effects in preference between extension types of fashion brand and regulatory focus. But there was no difference in preference toward extension products according to types of preannouncing and regulatory focus. Lastly, fashion brand extension types, preannouncing and regulatory focus showed significant interaction effects on preference. Thus even in cases of non-similar brand extensions which carry more risk of failing, the appropriate marketing communication strategies such as preannouncing will result in brand preference. Also marketing activities should be comprehensive and strategical based on consumers’ tendencies in order to derive positive evaluations.

Effectiveness of Autogenic Training in improving motor performances in Parkinson's disease

Relaxation training can be an important adjunct in reducing symptoms associated with Parkinson's disease (PD). Autogenic Training (AT) is a simple, easily administered and inexpensive technique for retraining the mind and the body to be able to relax. AT uses visual imagery and body awareness to promote a state of deep relaxation. To investigate whether AT when used as an adjunct to Physiotherapy (PT) improves motor performances in PD in comparison with a control group receiving PT alone. Randomized, controlled, single blinded trial. Movement Disorder Clinic and Department of Physiotherapy, Sree Chithira Thirunal Institute of Medical Sciences and Technology in Trivandrum, Kerala, India. Patients with PD of grade 2 or 3 of Hoehn & Yahr (H&Y) scale (N = 66). AT group or control group. The techniques were administered by Physiotherapists trained in AT and consisted of 40 sessions per patient over 8 weeks. Motor score subscale of Unified Parkinson's Disease Rating Scale (UPDRS) was used to measure the motor performances. The primary outcome measure was the difference in Motor score subscale of UPDRS scores between Week 1 (pretest score), Week 8 (posttest score), and follow-up at Week 12 after randomization. The simple main effects analysis showed that the AT group performed better than the control group in weeks 8 and 12 (P < .005). Patients in the AT and control groups reported a 51.78% and 35.24% improvement, respectively, in their motor performances in Week 8 compared with that in Week 1, which persisted, in the follow-up (Week 12) as 30.82% in the AT group and 21.42% in the control group. This study provides evidence that AT when used as an adjunct to PT is more effective than PT alone in improving motor performances in PD patients.

Effectiveness of myofascial release in the management of plantar heel pain: A randomized controlled trial

BackgroundPrevious studies have reported that stretching of the calf musculature and the plantar fascia are effective management strategies for plantar heel pain (PHP). However, it is unclear whether myofascial release (MFR) can improve the outcomes in this population. ObjectiveTo investigate whether myofascial release (MFR) reduces the pain and functional disability associated with plantar heel pain (PHP) in comparison with a control group receiving sham ultrasound therapy (SUST). DesignRandomized, controlled, double blinded trial. SettingNonprofit research foundation clinic in India. MethodSixty-six patients, 17 men and 49 women with a clinical diagnosis of PHP were randomly assigned into MFR or a control group and given 12 sessions of treatment per client over 4 weeks. The Foot Function Index (FFI) scale was used to assess pain severity and functional disability. The primary outcome measure was the difference in FFI scale scores between week 1 (pretest score), week 4 (posttest score), and follow-up at week 12 after randomization. Additionally, pressure pain thresholds (PPT) were assessed over the affected gastrocnemii and soleus muscles, and over the calcaneus, by an assessor blinded to the treatment allocation. ResultsThe simple main effects analysis showed that the MFR group performed better than the control group in weeks 4 and 12 (P<0.001). Patients in the MFR and control groups reported a 72.4% and 7.4% reduction, respectively, in their pain and functional disability in week 4 compared with that in week 1, which persisted as 60.6% in the follow-up at week 12 in the MFR group compared to the baseline. The mixed ANOVA also revealed significant group-by-time interactions for changes in PPT over the gastrocnemii and soleus muscles, and the calcaneus (P<0.05). ConclusionsThis study provides evidence that MFR is more effective than a control intervention for PHP.
