Body language is a form of communication between human beings. Facial expressions are a form of nonverbal communication. Facial expressions can often communicate a person\'s mood than a word. Here, the authors extract the facial features from facial points. Extracted feature points are tracked using a cross-correlation based optical flow to extract feature vectors. These vectors are used to categorize expressions, using RBF neural networks and Fuzzy Inference System. Recognition results from two classifiers are compared with each other.

Objectives: Marital satisfaction is one of the main determinants of a family\'s correct function thus, the present study aims to investigate the veterans\' compatibility with their wives and dependence on others and some factors affecting marriage compatibility. Materials: The present cross-sectional, analytical study was conducted on 200 veterans exposed to chemicals who were covered by the Foundation of Martyrs and Veterans Affairs, Gilangharb, Kermanshah, Iran. The study sample size was determined according to Krejcie and Morgan formula and the subjects were selected through simple random sampling. The study data were collected using marriage compatibility questionnaire, illogical thoughts questionnaire, and dependence on others questionnaire. The study data were analyzed using the SPSS statistical software (version18). Pearson correlation coefficient, multiple regression, and t-test were used in order to determine the relationships among the variables and compare the means. Results: The findings of the current study revealed no significant relationship between dependence on others, anxious attention, helplessness, avoiding problems, perfectionism, and autonomy and marriage compatibility. However, a significant relationship was found between failure and marriage compatibility. Discussion: Overall, the findings of the present study showed that the veterans of Gilangharb did not have disorders, but depended on others, particularly their spouses, due to their abnormal physical status. Sometimes, they cannot even do their personal tasks which results in their dependence on others eventually putting the veterans under pressure and stress.

The present study examined the relationships between, multi- dimensional constructs of organizational justice and organizational commitment with organizational citizenship behavior and employees’ performance in the NIORDC Company. The data were collected by self-administered questionnaires delivered to 200 employees who are working in divided work groups. Statistical methods and Structural equation modeling showed that distributive justice, procedural justice and interactional justice had the strongest positive effects on organizational commitment and organizational citizenship behavior and job performance. Also it is showed that all dimensions of organizational commitment had the strongest positive effects on organizational citizenship behavior and normative commitment and affective commitment were associated positively with job performance, but continuance commitment was non-significant to job performance.

This paper deals with a Short Combo option strategy and its application in hedging against an underlying price increase assuming that the given underlying asset will be bought in the future. The key difference between this paper and the previous studies is that we concentrated on single barrier options. Barrier options were formed to provide risk managers with cheaper means to hedge their exposures without paying for the price changes they believed unlikely to occur. The methodology is based on the profit functions in analytical form. We propose various hedging possibilities and show their practical application. In our analysis we used vanilla and barrier European options on SPDR Gold Shares. The results show that the Short Combo strategy formation using barrier options gives the end-users greater flexibility to express a precise view in the specific future price situations.

ABSTRACT Otolaryngology disorders are important aspect of medicine and affect the quality of life of patients and resulted in impairments of daily activity. Traditional and complementary medicine is considered as adjuvant therapy as well as modern methods of treatments in control of diseases. Therefore in this review article we examined some of traditional and alternative therapies in different part of the world particularly Iranian traditional medicine. Discussion about alternative medicine includes nutrients, botanicals and procedures. These sources of agents provided a wide range of agents for patients to achieve their goals in management of their problems.

Background Dermatophagoides farinae and Dermatophagoides pteronyssinus are House dust mites (HDM) that they cause severe asthma and allergic symptoms. Tropomyosin (TPM) protein and plays an important role in immune and allergic reactions to HDMs. Here, TPM protein from Dermatophagoides spp.was comprehensively screened in silico for its allergenicity, antigenicity and similarity/conservation.\nMaterials and Methods: The amino acid sequences of D. farinae TPM, D. pteronyssinus and other mites were retrieved. We included alignments and evaluated conserved/ variable regions along sequences, constructed their phylogenetic tree and estimated overall mean distances. Then, followed by with prediction of linear B-cell epitope based on different approaches, and besides in-silico evaluation of IgE epitopes allergenicity (by SVMc, IgE epitope, ARPs BLAST, MAST and hybrid method). Finally, comparative analysis of results by different approaches was made.\nResults: Alignment results revealed near complete identity between D. farina and D. pteronyssinus members, and also close similarity among Dermatophagoides spp. Most of the variations among mites\' TPM were approximately located at amino acids 23 to 80, 108 to 120, 142 to 153 and 220 to 230. Topology of tree showed close relationships among mites in TPM protein sequence, although the TPM sequences in D. farina, D. pteronyssinus and Psoroptes ovis are more similar to each other and clustered. Dermanyssus gallinae (AC: Q2WBI0) has less relationship to other mites, being located in a separate branch. Hydrophilicity and flexibility plots revealed that many parts of this protein have potential to be hydrophilic and flexible. Surface accessibility represented 7 different epitopes. Beta-turns in this protein are with high probability in the middle part and its two terminals. Kolaskar & Tongaonkar method analysis represented 11 immunogenic epitopes between amino acids 7-16. From comparative analysis of predicted probable consensus epitope regions by machine learning approaches these epitopes were gained: AA23-48, AA59-80, AA91-110, AA114-143, AA154-168, AA182-200, AA208-225, and AA254-272. Prediction of allergenic proteins by AlgPred server showed 10 matches for IgE epitope, and prediction by hybrid approach showed that IgE epitope is undoubtedly the major allergen.\nConclusion: Immunoinformatic approaches in allergenic protein analysis are now reliable tools for explanation/interpretation of clinically observed complexities. Results of present study, would help in HDM immunotherapy against several species of parasites as a wide range epitopic desensitization or prevention (vaccine) regime.
