Leveraging Pre-trained Language Models for Time Interval Prediction in Text-Enhanced Temporal Knowledge Graphs
Most knowledge graph completion (KGC) methods learn latent representations of
entities and relations of a given graph by mapping them into a vector space.
Although the majority of these methods focus on static knowledge graphs, a
large number of publicly available KGs contain temporal information stating the
time instant/period over which a certain fact has been true. Such graphs are
often known as temporal knowledge graphs. Furthermore, knowledge graphs may
also contain textual descriptions of entities and relations. Both temporal
information and textual descriptions are not taken into account during
representation learning by static KGC methods, and only structural information
of the graph is leveraged. Recently, some studies have used temporal
information to improve link prediction, yet they do not exploit textual
descriptions and do not support inductive inference (prediction on entities
that have not been seen in training).
We propose a novel framework called TEMT that exploits the power of
pre-trained language models (PLMs) for text-enhanced temporal knowledge graph
completion. The knowledge stored in the parameters of a PLM allows TEMT to
produce rich semantic representations of facts and to generalize on previously
unseen entities. TEMT leverages textual and temporal information available in a
KG, treats them separately, and fuses them to get plausibility scores of facts.
Unlike previous approaches, TEMT effectively captures dependencies across
different time points and enables predictions on unseen entities. To assess the
performance of TEMT, we carried out several experiments including time interval
prediction, both in transductive and inductive settings, and triple
classification. The experimental results show that TEMT is competitive with the
state-of-the-art.Comment: 10 pages, 3 figure

Twenty-five gifted students from Turkey-İstanbul participated in this study. “Environmental Affect Scale” and “Environmental Behavior Scale” were used, and semi-structured interviews were conducted. Results showed that out-of-school activities positively affected the students’ affective and behavioral tendencies toward the environment. It was also found that the awareness of students on environmental problems increased, and they began to produce their solutions to these problems
Increased Levels of Anxiety, Depression, and Secondary Trauma in Radiation Oncologists during COVID-19 Pandemic: A Preliminary Report from Turkey
OBJECTIVE We surveyed the anxiety, depression, and secondary trauma levels of Turkish Radiation Oncologists related with COVID pandemics. METHODS An anonymous online questionnaire survey was created to evaluate levels of depression, anxiety, and secondary trauma among Turkish Radiation Oncologists. The survey included demographics and occupational status, Secondary Traumatic Stress Scale (STSSS), The Beck Depression Inventory (BDI), The Beck Anxiety Inventory (BAI), and State-Trait Anxiety Inventory (STAI). RESULTS Seventy-two respondents provided the power of about 91.4% for the significance level of 0.05. The variance homogeneity was checked by the Levene test, the effect of COVID-19 on psychology is higher in the group of >19 (9.02 +/- 0.820), as well as the effect of social isolation (8.02 +/- 1.622), the STSS scores (34.28 +/- 9.062), the STAIS scores (60.46 +/- 5.296), the STAIT scores (82.21 +/- 9.298), the BDI scores (22.68 +/- 2.788), and the BAI scores (21.04 +/- 9.321). The multiple regressions to estimate BDI revealed statistically significant effects in STAIS, BAI, and STAIT. There is a significant correlation between STSS, STAIS, STAIT, BDI, BAI, the effect of COVID-19 on psychology, and the effect of social isolation. CONCLUSION We have established one of the first studies demonstrating the effects of COVID-19 pandemic on depression, anxiety levels, and secondary trauma on a special physician population, the Radiation Oncologists, who specifically do not directly take part in COVID19 management
Symbiotic Child Emotional Support with Social Robots and Temporal Knowledge Graphs
In current youth-care programs, children with needs (mental health, family issues, learning disabilities, and autism) receive support from youth and family experts as one-to-one assistance at schools or hospitals. Occasionally, social robots have featured in such settings as support roles in a one-to-one interaction with the child. In this paper, we suggest the development of a symbiotic framework for real-time Emotional Support (ES) with social robots Knowledge Graphs (KG). By augmenting a domain-specific corpus from the literature on ES for children (between the age of 8 and 12) and providing scenario-driven context including the history of events, we suggest developing an experimental knowledge-aware ES framework. The framework both guides the social robot in providing ES statements to the child and assists the expert in tracking and interpreting the child's emotional state and related events over time
Prominent response with helical tomotherapy in recurrent ameloblastic carcinoma of maxillary sinus: a case report
INTRODUCTION: Ameloblastoma is a benign but locally aggressive tumor of odontogenic epithelial tissue. Reports of radiotherapy treatment modalities are limited in the literature. CASE PRESENTATION: A thirty-five year old male presented with complaints of headache radiating to his face for about six months and impaired vision. The patient’s Positron Emission Tomography (PET) showed a mass in the left maxillary sinus extending to the nasal cavity and invading the adjacent tissues. An R2 (macroscopic residual tumor) surgical resection performed to debulk the tumor. Due to the recurrence and residual mass, the patient was treated with helical tomotherapy. At 2 months post-radiotherapy, patient’s vision returned to normal. PET scan showed a significant reduction in lesion size 12 months post-radiation. CONCLUSION: In cases of ameloblastic carcinoma with, post-surgical recurrence or patients not suitable for surgical treatment, helical tomotherapy can be an effective treatment option

Assessment of the Quality and Reliability of Information on Nutrition After Bariatric Surgery on YouTube
Background YouTube (TM) is a platform that many people, including patients, use to access health information. Recent studies have revealed that videos on YouTube (TM) are misleading or that medical videos may not contain appropriate information. This study aimed to assess the quality and reliability of videos on nutrition after bariatric surgery. Materials and Methods The keywords "after bariatric surgery diet" and "weight loss surgery postop diet" were used, and the first 100 videos for each keyword on YouTube (TM) were analyzed by considering the source, duration, content, and the number of likes of the video. The popularity of the video was calculated using the video power index (VPI) and view rate. The educational quality of the videos was evaluated using the DISCERN score, the Journal of the American Medical Association (JAMA) score, the Global Quality Score (GQS), the usefulness score, and a novel postoperation nutrition score (PONS). Results One hundred fourteen patients were included in the study. The mean duration and number of views were 12.51 min and 87,558.46, respectively. The DISCERN score, JAMA score, GQS, and usefulness score of the physicians or dietician-based videos were significantly higher than those of the patient-based videos (p < 0.001). Positive correlations were found between the VPI and view ratio, as well as between the duration and number of likes. Additionally, the DISCERN score was significant correlated with the duration and number of likes. Significantly positive correlations were found between the usefulness score and duration, usefulness score and number of likes, and PONS and duration (p < 0.01). Conclusions Informational videos on nutrition after bariatric surgery on YouTube (TM) are of low quality. Although the videos uploaded by physicians and dieticians have higher quality, only a few are available. Additionally, patients prefer to watch low-quality videos
Effect of Pilates Exercises on the Body Composition of Fasting Females
Objective: This study aimed to evaluate the changes in the body composition of individuals who fasted and did Pilates at least twice a week during Ramadan versus those who fasted but did no Pilates. Methods: This was an experimental study conducted on 60 healthy women who were admitted to the Noi Pilates in Istanbul Turkey, which was a private Pilates studio. The study was carried out on 60 grown-up, healthy women between 18 and 65 years of age who fasted in Ramadan 2019, some of whom did Pilates and some who did not. The women involved in the study had been doing Pilates for 6 months prior to Ramadan and did Pilates at least 3 times a week during Ramadan. Results: Significant increases were observed in body mass index (BMI), triceps skin-fold thickness (SFT), muscle mass and fat percentage in the fasting and non-pilates group (p<0.05). Our study found the change in the percentage of triceps SFT and fat in women who did Pilates to be more than those who did not. BMI, muscle mass, waist circumference and hip circumference of women who did Pilates and who did not do Pilates during Ramadan did not differ compared to the first measurements, and neither of the two methods dominated in terms of these variables. Conclusion: While a long period of fasting in Ramadan leads people to inactivity, personalized exercise and nutrition programs planned by experts may result in weight loss, especially for obese and slightly overweight people
