Studies on automatic dialogue systems, which allow people and computers to communicate with each other using natural language, have been attracting attention. In particular, the main objective of a non-task-oriented dialogue system is not to achieve a specific task but to amuse users through chat and free dialogue. For this type of dialogue system, continuity of the dialogue is important because users can easily get tired if the dialogue is monotonous. On the other hand, preceding studies have shown that speech with humorous expressions is effective in improving the continuity of a dialogue. In this study, we developed a computer-based humor discriminator to perform user- or situation-independent objective discrimination of humor. Using the humor discriminator, we also developed an automatic humor generation system and conducted an evaluation experiment with human subjects to test the generated jokes. A t-test on the evaluation scores revealed a significant difference (P value: 3.5×10-5) between the proposed and existing methods of joke generation.

Introduction: Non-stress test (NST) is the most common antenatal test performed to assess the foetus at risk of intrauterine hypoxia. On the other hand non-reactivity detected by NST increases the interferences of pregnancy by Caesarean section.Methodology: A cross sectional descriptive study was carried out in the department of Obstetrics and Gynaecology at Dhaka National Medical College between July2007 and June 2008.Objectives: The objectives of the study were (1) To observe the mode of delivery in cases of non-reactive non stress test (NST) and (2) To evaluate perinatal outcome of non-reactive NST.Results: A total 137 high risk pregnant women were included in the study. Age of the women ranges from 16 to 32 years. The mean age of the women was 23.74 ± 3.71 year. Among them 44.53% were primaegravida and 55.47% were multigravida. Gestational age was between 35 and 42 weeks and mean gestational age was 38.34±1.42 weeks. Regarding foetal reactivity 61.3% (n=84) were reactive and 38.7 % (n=53) were non-reactive. Among the babies of non reactive NST 98.11% and 1.89% were delivered by caesarean section and vaginal delivery respectively. Whereas, 48.81% and 51.19% babies of reactive NST were delivered by caesarean section and vaginal delivery respectively. The percentage of caesarean section was much higher in non-reactive NST cases in comparison to that of reactive NST which was statistically highly significant (p value 0.0000). One minute after birth APGAR scoring revealed that 56.6% and 43.4% newborn of non-reactive NST had no depression( APGAR score 7-10) and mild depression ( APGAR score 4-6) respectively. On the other hand 65.47% and 34.5% newborn of reactive NST had no depression and mild depression respectively at one minute after birth. Therefore, small difference was noticed in the neonatal status between the reactive and non-reactive NST which had no statistical significance (p value 0.507). Evaluation of the neonates with APGAR scoring done 5 minutes after birth revealed mild depression (APGAR score 4-6) in 24.53% and 20.24% of non-reactive and reactive NST cases respectively and no depression (APGAR score 7- 10) was found in 75.47% and 70.76% in reactive and nonreactive NST respectively. So, 5 minutes after birth the neonatal status among reactive and non-reactive NST made no significant difference (p value 0.9266).Conclusion: Neonatal evaluation revealed that all foetuses were not compromised as detected by NST. Relying on NST the rate of Caesarean section has been increased. Reassessment of the foetal conditions was needed with the help of other techniques. Therefore NST alone is insufficiently predictive of neonatal outcome.J Bangladesh Coll Phys Surg 2015; 33(2): 65-69

Background: CT-scan findings give a well delineated impression on hepatic mass. Objective: The purpose of the present study was to observe the CT-scan findings of hepatic mass. Methodology: This cross sectional study was carried out in the department of Radiology and Imaging MMC in collaboration with the same department of BSMMU, DMC, Dhaka during the period of 1st January 2006 to 31st December 2007 to establish the usefulness of CT scan in the diagnosis of hepatic mass and its validity by determining sensitivity, specificity, PV, NPV, and accuracy. A total of 50 patients were admitted in the Department of Medicine and Department of Hepatobiliary of MMCH, BSMMU, and DMCH with the clinical diagnosis of fever, abdominal pain, anorexia, nausea/vomiting, loss of appetite, jaundice, weight loss and ascites. They were sent to the department of Radiology and Imaging and of respected hospitals for CT evaluation, confirmation and to see the extension for planning of proper management. Result: A total number of 50 hepatic mass patients were recruited in this study. CT findings of all patients showed 29 had lesions on right lobe, six patients had on left lobe and 15 patients had lesion on both lobe (p value <0.05). Among all patients 28 had multiple lesion, of them 71.4% was malignant and 28.6% was benign. On the other side 22 patients had solitary lesion, of them 36.4% was malignant and 63.6% was benign (p value <0.05). Among all malignant lesions 17 (60.7%) were hypodense, followed by 6 (21.4%) were isodense and 5 (17.9%) had mixed pattern of density. 12 (42.9%) patients of malignant diseases had ill-defined margin and 16 (57.1%) had well defined margin. 6 (27.3%) patients of benign lesions had ill-defined and 16 (72.7%) had well defined margin. No significant difference was observed. All malignant lesions (100%) and 77.3% benign lesions were enhanced after giving contrast. 16 (57.1%) malignant lesions were mildly enhanced, 10 (35.7%) were moderate and 2 (7.1%) were intensely enhanced. On the other side 8 (47.1%) benign lesions were mild, 35.5% were moderate and 3 (17.6%) were intensely enhanced. Conclusion: In conclusion hepatic mass is more common in right lobe of the liver of which multiple lesion is commonly found.Journal of Current and Advance Medical Research 2015;2(1):7-11DOI:  http://dx.doi.org/10.3329/jcamr.v2i1.22580

Background: Dysfunctional Uterine Bleeding (DUB) is a condition that affects nearly every woman at some point in her life. This study aims to compare the efficacy of Ormeloxifene and Norethisterone in reducing menorrhagia in such patients.Methods: This prospective study was done on 100 women presenting with dysfunctional uterine bleeding, of 20-50 years of age, who were ready for follow-up and were allocated into two equal groups, one was given Ormeloxifene and the other was given Norethisterone for a period of 3 months. Haemoglobin levels, endometrial thickness on ultrasound and Pictorial Blood loss Assessment Chart (PBAC) scores were assessed before and after the treatment.Results: It was found that both Ormeloxifene and Norethisterone reduced menorrhagia, with a significant difference in PBAC scores (p value <0.05). There was a notable reduction in PBAC scores in Ormeloxifene group (66.53% change from pretreatment mean value) as compared to Norethisterone group (31.38% change from pretreatment mean value); and same holds true for the change in haemoglobin levels as well as endometrial thickness. Ormeloxifene was found to have a greater effect on heavy menstrual bleeding in comparison to Norethisterone.Conclusions: Ormeloxifene is a new modality and is found to be a better option in reducing menorrhagia in DUB in respect to a greater success rate, better compliance and cost effectiveness.

Multimodality in dialogue systems has opened up new frontiers for the creation of robust conversational agents. Any multimodal system aims at bridging the gap between language and vision by leveraging diverse and often complementary information from image, audio, and video, as well as text. For every task-oriented dialog system, different aspects of the product or service are crucial for satisfying the user’s demands. Based upon the aspect, the user decides upon selecting the product or service. The ability to generate responses with the specified aspects in a goal-oriented dialogue setup facilitates user satisfaction by fulfilling the user’s goals. Therefore, in our current work, we propose the task of aspect controlled response generation in a multimodal task-oriented dialog system. We employ a multimodal hierarchical memory network for generating responses that utilize information from both text and images. As there was no readily available data for building such multimodal systems, we create a Multi-Domain Multi-Modal Dialog (MDMMD++) dataset. The dataset comprises the conversations having both text and images belonging to the four different domains, such as hotels, restaurants, electronics, and furniture. Quantitative and qualitative analysis on the newly created MDMMD++ dataset shows that the proposed methodology outperforms the baseline models for the proposed task of aspect controlled response generation.

Ceramic Restorations

Typically, prosthodontists adjust ceramic restorations glazed surface by grinding prior to insertion. Such alterations of surfaces are necessary for the correction of occlusal interferences. We aimed to evaluate and compare the change in flexural strength of ceramic surfaces after re-glazing and polishing. This study included 40 samples of ceramic blocks that were fabricated and glazed, and then fired in accordance with the manufacturer’s recommendations. The sample was randomly divided into four groups of 10 samples each. The first group was the control group with unaltered glazed samples. The second group was abraded with an extra-fine diamond bur followed by re-glazing, and the other two groups were polished with two commercially available polishing kits after abrading them with an extra-fine diamond bur. The samples were tested for their flexural strength using a universal testing machine. On the application of the F test on the means of all the groups, a value greater than 0.05 was found, which meant that there is no statistically significant difference in flexural strength values between the groups (P-value>0.05). Since the flexural strength values of the polished group were comparable to the other groups, polishing can be used instead of re-glazing for ceramic restorations. This reduces an additional clinical appointment for the patient and saves working time.

Gastrointestinal microbiome dysbiosis may result in harmful effects on the host, including those caused by inflammatory bowel diseases (IBD). The novel probiotic BIOHM, consisting of Bifidobacterium breve, Saccharomyces boulardii, Lactobacillus acidophilus, L. rhamnosus, and amylase, was developed to rebalance the bacterial–fungal gut microbiome, with the goal of reducing inflammation and maintaining a healthy gut population. To test the effect of BIOHM on human subjects, we enrolled a cohort of 49 volunteers in collaboration with the Fermentation Festival group (Santa Barbara, CA, USA). The profiles of gut bacterial and fungal communities were assessed via stool samples collected at baseline and following 4 weeks of once-a-day BIOHM consumption. Mycobiome analysis following probiotic consumption revealed an increase in Ascomycota levels in enrolled individuals and a reduction in Zygomycota levels (p value < 0.01). No statistically significant difference in Basidiomycota was detected between pre- and post-BIOHM samples and control abundance profiles (p > 0.05). BIOHM consumption led to a significant reduction in the abundance of Candida genus in tested subjects (p value < 0.013), while the abundance of C. albicans also trended lower than before BIOHM use, albeit not reaching statistical significance. A reduction in the abundance of Firmicutes at the phylum level was observed following BIOHM use, which approached levels reported for control individuals reported in the Human Microbiome Project data. The preliminary results from this clinical study suggest that BIOHM is capable of significantly rebalancing the bacteriome and mycobiome in the gut of healthy individuals, suggesting that further trials examining the utility of the BIOHM probiotic in individuals with gastrointestinal symptoms, where dysbiosis is considered a source driving pathogenesis, are warranted.

The dialogue system has always been one of the important topics in the domain of artificial intelligence. So far, most of the mature dialogue systems are task-oriented based, while non-task-oriented dialogue systems still have a lot of room for improvement. We propose a data-driven non-task-oriented dialogue generator “CERG” based on neural networks. This model has the emotion recognition capability and can generate corresponding responses. The data set we adopt comes from the NTCIR-14 STC-3 CECG subtask, which contains more than 1.7 million Chinese Weibo post-response pairs and 6 emotion categories. We try to concatenate the post and the response with the emotion, then mask the response part of the input text character by character to emulate the encoder-decoder framework. We use the improved transformer blocks as the core to build the model and add regularization methods to alleviate the problems of overcorrection and exposure bias. We introduce the retrieval method to the inference process to improve the semantic relevance of generated responses. The results of the manual evaluation show that our proposed model can make different responses to different emotions to improve the human-computer interaction experience. This model can be applied to lots of domains, such as automatic reply robots of social application.

Weaver ants Oecophylla smaragdina are social insects that recognize nestmates using pheromone. This study analyzes the feeding behavior and nestmate recognition of weaver ants in the urban area of three different islands (Sumatra: Baturaja; Java: Banyuwangi; Papua: Sorong). The free ants were placed in the arena composed of chicken meat, sugar, bananas as the baits. Ten trapped ants were also located in the arena to explore the nestmate recognition between the free and the trapped ants. Five types of behaviors, i.e., approach, stalking, communication, competition, and agonistic, were recorded in 6 days. Food preferences were indicated by the number of conduct towards the feeding sites, and nestmate recognition was indicated by approaching the trapped nestmate. The results showed that the percentage of the approach behavior of free ants was the highest in the three islands but had no significant difference between Sumatra and Java and between Java and Sorong (p-value >0.05). However, the study showed significant differences for the other four behaviors observed. As predicted, the percentage of chicken meat foraged by the ants was the highest due to the carnivorous behavior. The free ants showed the nestmate recognition to the trapped ants in all behavior, except competition.

Abstract Background Vitamin D deficiency and insufficiency have become a common problem worldwide. Vitamin D has been associated with all causes of mortality in chronic diseases and associated with a longer hospital stay and poor outcome. Aim of the Study to evaluate the role of vitamin D supplementation on the outcome of hospitalization for patients with CLD or CHF admitted to Ain Shams University Hospitals (ASUH) with acute deterioration of their illness. Subjects and methods We conducted prospective case control on 80 patients collected from inpatient ward of endocrinology, divided into 2 groups; 40 patients with chronic liver diseases and 40 patients with heart failure. Serum 25OH-vitamin D and calcium, phosphate and PTH were measured to all participants before intervention. 20 patients of each group (Intervention group) received single dose of vitamin D within 3 days of admission and the other 20 patients of each group (control group) did not receive vitamin D vitamin D. Results no significant difference between patients who received vitamin D supplementation and who did not receive vitamin D supplementation as regards outcome and survival with P value 1.000 in patients with CLD and 0.823 in patients with CHF. On the other hand, we found baseline vitamin D level was an independent predictor of mortality (P value .018). Conclusion We found that a beneficial effect of vitamin D supplementation can't be achieved with single dose vitamin D (200,000 IU) on CHF or CLD hospitalized patients’ mortality. We recommend that vitamin D supplementation should be considered in CLD and CHF outpatients, with exception of hypercalcemic and hyperphosphatemic patients, as baseline vitamin D status affects the disease course and mortality prior to disease deterioration and hospitalization.

<div><p>Dialog state tracking (DST) plays a critical role in cycle life of a task-oriented dialogue system. DST represents the goals of the consumer at each step by dialogue and describes such objectives as a conceptual structure comprising slot-value pairs and dialogue actions that specifically improve the performance and effectiveness of dialogue systems. DST faces several challenges: diversity of linguistics, dynamic social context and the dissemination of the state of dialogue over candidate values both in slot values and in dialogue acts determined in ontology. In many turns during the dialogue, users indirectly refer to the previous utterances, and that produce a challenge to distinguishing and use of related dialogue history, Recent methods used and popular for that are ineffective. In this paper, we propose a dialogue historical context self-Attention framework for DST that recognizes relevant historical context by including previous user utterance beside current user utterances and previous system actions where specific slot-value piers variations and uses that together with weighted system utterance to outperform existing models by recognizing the related context and the relevance of a system utterance. For the evaluation of the proposed model the WoZ dataset was used. The implementation was attempted with the prior user utterance as a dialogue encoder and second by the additional score combined with all the candidate slot-value pairs in the context of previous user utterances and current utterances. The proposed model obtained 0.8 per cent better results than all state-of-the-art methods in the combined precision of the target, but this is not the turnaround challenge for the submission.</p></div>
