The applicability of main scarp upper edge (MSUE) as dependent variable representation was performed in a translational slide susceptibility zonation of the Milia and Roglio basins, Italy. Two landslide inventories were built thanks to detailed geomorphological mapping and aerial photograph analysis. The landslides were used to create the models before 1975, while those after 1975 were employed to validate the predictive power of the model. Possible landslide-related factors were chosen from a geomorphological survey. The inventory landslide maps and the landslide-related factor maps were processed by conditional analysis, producing landslide susceptibility maps with five susceptibility classes. A comparison between the distribution of landslides after 1975 and those derived from models provided the predictive power of each model, which in turn was used to define the best predictive model. Reduced chi-square analysis allowed to define the efficiency of MSUE as dependent variable representation. MSUE can be applied as dependent variable representation to landslide susceptibility zonation with appreciable results. In the Roglio basin, slope angle, distance from streams, and from tectonic lineaments proved to be the main controlling factors of translational slides, whereas in the Milia basin, lithology and slope angle gave more satisfactory results as landslide-predisposing factors.

e16211 Background: Nuclear factor E2-related factor-2 (NFE2L2) gene encodes a transcription factor which is a member of basic leucine zipper (bZIP) proteins family. Overexpression of NFE2L2 lead to cell proliferation and promoted tumor metastasis. Previous report indicated that NFE2L2 mutation (NFE2L2-MT) was an independent poor prognostic factor in esophageal squamous cell carcinoma (ESCC). However, the correlation between NFE2L2 mutation and pan-cancer types of TMB, MSI, and PD-L1 expression is unclear. Methods: TMB analysis was performed in 3,716 Chinese pan-cancer patients who underwent NGS sequencing using a 539 gene panel. The TMB calculation included synonymous and nonsynonymous mutations and InDels. MSI analysis was performed in 3,110 patients. MSI-H was defined as above 10% positive of the 195 tested microsatellites sites. The PD-L1 expression analysis was performed in 3,415 patients with immunohistochemistry staining (IHC) by antibody SP263. PD-L1 positive was defined as greater than or equal to 1%. The statistical correlation was investigated using Chi-square analysis. TMB value was compared using Wilcoxon Rank Sum test. We used TCGA public database to verify the result. Results: The mutation frequency of NFE2L2 mutation was 2.66% (99/3716). The TOP 5 cancer types were liver cancer 3.53% (14/397), lung cancer 2.97% (42/1416), colorectal cancer 2.02% (7/347), gastric cancer 1.36% (3/221), soft tissue sarcoma 0.53% (1/189). NFE2L2-MT had a significant correlation with higher TMB (p = 2.2e-16), compared with NFE2L2 wild-type (NFE2L2-WT). Among 3110 samples with MSI status, the MSI-H percentage of NFE2L2-MT and NFE2L2-WT were 8.60% (8/93) and 1.33% (40/3017), respectively (p = 1.29e-7). In 3,415 patients with PD-L1 protein expression information, the PD-L1 positive percentage of NFE2L2-MT and NFE2L2-WT were 51.52% (51/99) and 61.9% (1,268/2,048), respectively. NFE2L2-WT has higher PD-L1 positive percentage than NFE2L2-MT (p = 0.01). NFE2L2-MT was significantly correlated with higher TMB and MSI when we used TCGA data to verify, p<0.0001. However, the survival analysis of 1661 MSKCC immunotherapy cohort showed that the median OS of NFE2L2-MT vs NFE2L2-WT was 21 months vs 18 months (p=0.858), but the difference was not significant. Conclusions: NFE2L2 mutation has a very significant correlation with higher TMB and MSI, but not related to PD-L1 expression. However, whether NFE2L2-MT is related to the efficacy of immunotherapy was still unclear and more clinical data were needed.

We previously demonstrated the success of in vitro embryo production (IVP) in Lidia breed cattle (Gamarra Lazo et al. 2017 Reprod. Fertil. Dev. 30, 187). As in other species, the success of IVP is linked to the birth of calves from this technique. In the Lidia breed, an important factor to consider is the use of Lidia recipients in order to keep the temperament characteristic of this breed to next generations. The aim of the study was to produce ovum pickup (OPU)-IVP calves in the Lidia breed and to assess the effects of recipient and embryo related factors (status of the recipients; development stage of IVF embryos) on pregnancy rate following embryo transfer. Ovum pickup-IVP embryos from Lidia breeds were produced by a standard protocol (Gamarra Lazo et al. 2017 Reprod. Fertil. Dev. 30, 187). Numbers of blastocysts and expanded blastocysts were recorded on Day 7. A total of 27 blastocysts (B) and 34 expanded blastocysts (EB) of excellent quality (grade 1 according to IETS classification) were selected for fresh transfer. All embryos were transferred to Lidia breed recipients (heifers or cows) by a single operator under similar environmental and field conditions. Recipients were synchronized by subcutaneous insertion of an ear implant of 3.3mg of Norgestomet (Crestar®, MSD, Courbevoie, France) for 9 days. Two days before implant withdrawal, 0.5mg of Cloprostenol (Estrumate®, MSD) was injected. No oestrous detection was performed and synchronized females were selected as recipients when they presented a well developed corpus luteum at Day 9 after implant withdrawal (Day 6 to 7 after the expected oestrus). Blood samples were collected from recipients to determine pregnancy status using the bovine pregnancy associated glycoprotein (Idexx, Westbrook, ME, USA) 50-60 days after transfer. Pregnancy rates were analysed by chi-square analysis to compare results between heifers and cows and between B and EB embryo stages. The overall pregnancy rate after transfer of IVP fresh embryos from Lidia breed averaged 41.0% (n=25). A higher pregnancy rate was achieved in cows compared to heifers [51.2% (21/41) v. 20.0% (4/20) respectively, P&lt;0.05]. There was no difference in pregnancy rate between grade 1B [37% (10/27)] and EB [44.1% (15/34)] embryos (P&gt;0.05). Surprisingly, these results suggest that Lidia breed cows are the best recipients for OPU-IVP embryos. This may be related to the limited feasibility of manipulating the uterine horn during the embryo transfer in Lidia breed heifers, which have a low weight (less than 280kg) and present a narrow rectum diameter. It has been also observed that the cervix is very thin and difficult to cross, thus increasing the stress and potentially inflammatory and immune products secretion. Development stage of embryos did not affect pregnancy rate. To our knowledge, no OPU-IVP Lidia breed calves have been reported previously following transfer into Lidia breed recipients. In the current work, 13 OPU-IVP Lidia breed calves were born. Therefore, we confirmed the possibility of applying OPU-IVP and embryo transfer techniques in this breed within a genetic program.

Background:  In order to build a culture of well-being among students in post-secondary academic communities, an assessment of current well-being and related factors is necessary. Common barriers to optimal well-being may include stress, anxiety, and depression in college students. Low levels of well-being have been associated with higher levels of impaired academic performance. Aim: Explore the relationship between academic success and time spent performing well-being activities. Methods:  Seligman’s Well-Being Theory was used to guide this study. The relationship between well-being and academic success of undergraduate students at a large Midwestern university (N = 5008) was evaluated using data from a 278 item 2018 Student Experience at a Research University (SERU) survey. Measures of academic success included late assignments, going to class unprepared, and skipping class. Measures of well-being included time spent in: physical exercise, spiritual practice, community service, and club participation; time with family and friends were also included. Results: Pearson Chi-Square analysis revealed a total of five significant relationships between well-being activities and late assignments, being unprepared for class, and skipping class at α=.05. Conclusions:  Further research is needed to understand the relationship between well-being and academic success to guide development of strategies to support well-being in university students.

The objective of this study was to identify the interactions between impairment-related and work-related factors associated with recommendations for specific assistive technology devices (ATDs) for persons with mobility limitations who used workplace accommodation (WA) services. A retrospective and secondary data analysis was conducted on 132 WA service users with mobility limitations in Taipei City from 2008 to 2012 using chi-square automatic interaction detector (CHAID). The CHAID analyses revealed interactions between impairment-related factors (difficulty walking and upper extremity pain) and work-related factors (frequent moving around outdoors), which were significantly associated with the recommendation of powered wheelchairs ( p < .05). Interactions between the impairment-related factor (difficulty walking) and the work-related factor (frequent sitting for long periods of time) were associated with the recommendation of ergonomic chairs ( p < .001) for persons with mobility limitations. By identifying the interactions between impairment-related and work-related factors in recommending workplace ATDs for persons with mobility limitations, this study provides evidence-based ATDs recommendations for persons with mobility limitations.

Objective: This study was conducted in order to evaluate healthy eating obsession-orthorexia nervosa and related factors in women. Method: The study was carried out 132 volunteer women aged between 20-54 years. Demographic characteristics, health information were taken and orthorexia nervosa-15 (ORTO-15) was applied by researcher with face to face method. Antropometric measurements were taken according to the rules. It was determinated that ORTO-15 score ≤40 is orthorexic and >40 is normal. Data was evaluated using chi-square, analysis of t-test and correlation analysis methods with SPSS16.0 program. Result: It was found that 75.8% of women has less than 40 points from ORTO-15 test. There is a negative correlation between ORTO-15 score with age (r =-0.183), body weight (r=-0.206) and BMI (r=-0.199) (p<0.05). It was seen that obsessional concerns such as choosing healthy food and this dietary pattern to be associated with physical appearance are common in orthorexic individuals. Conclusion: It was found that orthorexia tendency of women has higher. It has been observed that orthorexic tendencies are increased in individuals with high body weight and BMI values. Determination of obsessional concerns of orthorexic individuals will be useful in the classification of the disease and development of diagnostic criteria.

Abstract. The aim of this study is to identify the landslide predisposing factors' combination using a bivariate statistical model that best predicts landslide susceptibility. The best model is one that has simultaneously good performance in terms of suitability and predictive power and has been developed using variables that are conditionally independent. The study area is the Santa Marta de Penaguião council (70 km2) located in the Northern Portugal. In order to identify the best combination of landslide predisposing factors, all possible combinations using up to seven predisposing factors were performed, which resulted in 120 predictions that were assessed with a landside inventory containing 767 shallow translational slides. The best landslide susceptibility model was selected according to the model degree of fitness and on the basis of a conditional independence criterion. The best model was developed with only three landslide predisposing factors (slope angle, inverse wetness index, and land use) and was compared with a model developed using all seven landslide predisposing factors. Results showed that it is possible to produce a reliable landslide susceptibility model using fewer landslide predisposing factors, which contributes towards higher conditional independence.

The Relationship

Objective of this research; 1) determine the perception of ranchers against the properties and behavior of the leadership of the companion in the Society of Al-Awwaliyah 2) analyze the relationship between productivity breeder with productivity of livestock in the Society of Al-Awwaliyah 3) identify the relationship perceptions of ranchers against the leadership companion with productivity of livestock in the Society of Al-Awwaliyah , The data used in this study are primary and secondary data. Primary data were obtained from questionnaires which stem from ranchers while secondary data sourced from literature in the form of books and articles. Data processing was performed using Chi-square analysis using SPSS software version 21. One of the factors relating to the productivity of ranchers is the perception of ranchers against the leadership of their companion. Leadership companion views of the nature and behavior of which is owned by a companion. Productivity ranchers indirectly related to the productivity of the cattle business. Characteristics breeder visits of age, years of education, experience ranchers, and businesses in addition to ranchers. The results of data analysis showed that there is a significant relationship between business other than ranchers with ranchers productivity. The relationship between the perception of the nature of the companion breeder with productivity ranchers produce Pearson Chi-Square value is 9.751 and Asymp. Sig. (2-sided) of 0.002. This is due to interest ranchers against leadership qualities possessed by a companion who produce prolific ranchers. Ranchers consider that a companion of his leadership qualities are ideal as a companion.

This study aims to describe the effect of sanctions (individual sanctions, collective sanctions, and absence of sanctions) on cooperative behavior of individuals with medium trust in the context of corruption. Both collective sanctions and individual sanctions, are systemic, which means sanctioning behavior is exercised not by each individual but by the system. Cooperative behavior in this context means choosing to obey rules, to reject acts of corruption and to prioritize public interests rather than the personal interests. Conversely, corruption is an uncooperative behavior to the rules, and ignores the public interest and prioritizes personal interests. Research subjects were 62 students. The Chi-Square Analysis was used to see the association between the variables and the logistic regression model was applied to describe the structure of this association. Individual sanction is recommended as punishment to medium trust individuals to promote cooperative behavior in the context of corruption. The results showed that individuals with medium trust had more cooperative behavior.

Background Suppression is associated with binocular vision conditions such as amblyopia and strabismus. Commercial methods of testing fusion often only measure central fusion or suppression at near. The purpose of this pilot study was to assess a new iPad picture fusion test that assesses foveal and central fusion at near. Methods Participants aged 5 years and older presenting for eye examination at The Ohio State University College of Optometry were enrolled. Results from visual acuity, dry and wet refraction/retinoscopy, stereopsis and cover testing were recorded from the patient chart. The iPad picture fusion test, Worth four-dot, Worth type test with foveal letter targets, and Polarized four-dot were performed by one examiner in a randomized order at 40 cm. Testing was repeated with the anaglyphic filters reversed. Crosstabulation and McNemar chi-square analysis were used to compare the results between fusion testing devices. Results Of the fifty participants (mean age = 17.5), twelve reported suppression and one reported diplopia. Testability was excellent for all tests (98% to 100%). There were no significant differences between tests in reported results (P ≥ 0.22 for all comparisons). No difference in reported fusion or suppression status was observed with change in orientation of the anaglyphic filters. Six participants reported foveal suppression alone at near which was not identified with Worth four-dot at near. Conclusion The iPad picture fusion test provided excellent testability and agreement with commonly used tests of fusion and allowed testing of both central and foveal fusion at near. Nearly half (46%) of participants with suppression reported foveal suppression, supporting the importance of testing for foveal suppression.
