Background: Aggressive behavior of patients in psychiatric wards is one of the main challenges faced by healthcare workers. Despite the abundance of research on the frequency of aggressive behavior, not enough attention has been paid to its severity. Furthermore, limited studies have evaluated the restraint methods used to manage aggressive behaviors. Objectives: The current descriptive study aimed to compare the relationship between demographic characteristics, diagnosis of psychiatric illness, medical illness, and hospitalization characteristics with features of aggressive behavior in patients experiencing different types of restraint during hospitalization. Methods: We evaluated subjects admitted to the adult psychiatric wards of Imam Hossein and Taleghani hospitals in Tehran, Iran, in 2018. The patients were controlled by various restraint methods during hospitalization. All the patients were evaluated for the severity of aggression, which was determined utilizing the Persian version of the Modified Overt Aggression Scale (MOAS). All the data along with demographic and clinical characteristics obtained from medical records were analyzed using the Mann-Whitney and Kruskal-Wallis nonparametric test (P-value = 0.05) and Spearman correlation coefficient to describe the factors affecting the aggressive behavior of patients. Results: In this study, the prevalence of aggressive behavior was 11.7%. Among the demographic variables, gender (P-value = 0.003), education level (P-value = 0.05), and the history of aggressive behavior (P-value = 0.001) were significantly associated with the MOAS. Furthermore, as the hospitalization duration increased, the frequency of aggressive behavior decreased, and its severity intensified. Moreover, there was a significant relationship between aggression severity with admission type (P-value = 0.00), concurrent medical illness (P-value = 0.026), and substance abuse (P-value = 0.025). Conclusions: According to the obtained results, the factors affecting the aggression and early identification of patients with the potential of aggressive behavior is an effective management strategy for controlling these patients.

Background: Aggressive behavior (AB) represents an important social problem, which results in significant costs for the society. A significant role in developing aggression is suggested to be mediated by molecular mechanisms related to the functioning of oxytocin (OXTR) and arginine vasopressin receptor (AVPR1B) genes involved in the regulation of social behavior. On the other hand, a specificity of environmental factors affecting an individual at various stages of development may modulate the molecular processes, especially at gene expression level, thus affecting human’s ability to self-control and resulting in AB manifestation. The aim of the study: Considering a multifactorial nature of developing aggression, the present study is aimed to estimate both the genetic- and haplotype-based effects of the OXTR and AVPR1B genes and gene-by-environment interactions in developing AB. Materials and methods: The genotyping of the OXTR (rs2228485, rs53576) and AVPR1B (rs33911258) gene variants was conducted via PCR with fluorescent detection in 189 criminal offenders (7% women) from the Republic of Bashkortostan, who committed murders, and the control group (N=254, 12% women) corresponding to the group of criminal offenders by ethnicity and age. Statistical analysis was performed via logistic regression with correction for multiple comparisons (PLINK v.1.09). Results: As a result of statistical analysis the association of rs2228485 A-allele and AG haplotype (rs2228485 and rs53576) in the OXTR gene with an enhanced risk for developing AB was observed. In addition, we demonstrated a modulating effect of such environmental factors as the presence of severe somatic diseases, alcohol addiction, fa milial history of psychopathologies, income and education level. Moreover, the effect of rs33911258 G-allele in the AVPR1B gene on AB was observed. Conclusion: The data obtained evidence that the examined variants in the AVPR1B and OXTR genes in combination with specific environmental factors may affect neuronal systems functioning, thus resulting in the manifestation of antisocial behavior.

The purpose of this research is to explore the most common factors affecting aggressive behavior among vocational students in Malaysia. The samples were composed of 400 vocational college students based on the proportional stratified random sampling method. The research design used is the quantitative method of survey. The modified Buss-Perry Aggression Questionnaire was used to identify the level of aggressive behavior among vocational students. A pilot study was conducted to 35 vocational college students in Batu Pahat. Based on the findings of the pilot study, the Cronbach’s Alpha value item overall was 0.853. This indicates that the questionnaire items were valid and reliable to obtain data on the actual survey. A total of 400 students from vocational colleges were selected for this study by the proportional stratified random sampling. The data were analyzed using the Statistical Package for Social Science (SPSS) program version 25. Statistical techniques employed in the analysis of data collection were mean and standard deviation. The results showed that the majority of aggressive behavior of vocational students in Malaysia was at a moderate level. The findings of this study found that bad attitude, parents and electronic media were the factors of a moderate level aggressive behavior. Meanwhile, peer factor was at a high level in affecting aggressive behavior among vocational students in Malaysia. Furthermore, the study is expected to provide valuable information to teachers at vocational colleges to address social problems among the students for developing their character and moral toward excellence.

In our initial publication on this subject1) we reported results demonstrating that contrast is the most important factor in producing the high image quality required for reliable image analysis. We also listed the factors which enhance contrast in order of the experimentally determined magnitude of their effect. The two most powerful factors affecting image contrast attainable with sheet film are beam intensity and KV. At that time we had only qualitative evidence for the ranking of enhancing factors. Later we carried out the densitometric measurements which led to the results outlined below.Meaningful evaluations of the cause-effect relationships among the considerable number of variables in preparing EM negatives depend on doing things in a systematic way, varying only one parameter at a time. Unless otherwise noted, we adhered to the following procedure evolved during our comprehensive study:Philips EM-300; 30μ objective aperature; magnification 7000- 12000X, exposure time 1 second, anti-contamination device operating.

Strength And Stiffness

Processing polymers from the liquid crystalline state offers several advantages compared to processing from conventional fluids. These include: better axial strength and stiffness in fibers, better planar orientation in films, lower viscosity during processing, low solidification shrinkage of injection moldings (thermotropic processing), and low thermal expansion coefficients. However, the compressive strength of the solid is disappointing. Previous efforts to improve this property have focussed on synthesizing stiffer molecules. The effect of microstructural scale has been overlooked, even though its relevance to the mechanical and physical properties of more traditional materials is well established. By analogy with the behavior of metals and ceramics, one would expect a fine microstructure (i..e. a high density of orientational defects) to be desirable.Also, because much microstructural detail in liquid crystalline polymers occurs on a scale close to the wavelength of light, light is scattered on passing through these materials.

A statistical review provides analysis of four years of speech therapy services of a suburban school system which can be used for comparison with other school system programs. Included are data on the percentages of the school population enrolled in therapy, the categories of disabilities and the number of children in each category, the sex and grade-level distribution of those in therapy, and shifts in case-load selection. Factors affecting changes in case-load profiles are identified and discussed.
