As societies become increasingly diverse, mental health professionals need instruments for assessing emotional, behavioral, and social problems in terms of constructs that are supported within and across societies. Building on decades of research findings, multisample alignment confirmatory factor analyses tested an empirically based 8-syndrome model on parent ratings across 30 societies and youth self-ratings across 19 societies. The Child Behavior Checklist for Ages 6-18 and Youth Self-Report for Ages 11-18 were used to measure syndromes descriptively designated as , and .

Despite the relevant findings on non-average information processing rate (IPR) indicators-intelligence relation, and on age-related changes of some of these indicators during aging, the research on sex-specific age-related changes of these indicators during childhood and adolescence are lacking. In a transversal study, 1197 school children (598 girls) aged 8-18 have been individually measured on 5 IPR indicators--two averages (mean_t, median_t) and three non-averages (min_t, max_t, sd_t). The results corroborated the expected non-linear changes of average IPR indicators in the observed developmental period, whereby the sex difference in related developmental patterns was detected: marked age-related decrement in girls ceased at the age of 12, and in boys around the age of 13-14, after which progress in both sexes gradually ceased by the age of 18 and was less pronounced in girls.

Artificially synthesized probiotic from Lactobacillus strain, contained in the tested toothpaste, led to an innovative approach in preventive dentistry. A new concept resulting from this research can be explained due to possible mechanisms of action of probiotic bacteria, according to which equilibrium of hostile bacterial flora is achieved by mechanical elimination of cariogenic bacteria from the mouth. This research was conducted during a 4-week period on a randomly selected Croatian sample of 50 participants, with the aim to investigate the efficacy of the first probiotic toothpaste ever produced in Croatia.

Objective: To build on Achenbach, Rescorla, and Ivanova (2012) by (a) reporting new international findings for parent, teacher, and self-ratings on the Child Behavior Checklist, Youth Self-Report, and Teacher's Report Form; (b) testing the fit of syndrome models to new data from 17 societies, including previously underrepresented regions; (c) testing effects of society, gender, and age in 44 societies by integrating new and previous data; (d) testing cross-society correlations between mean item ratings; (e) describing the construction of multisociety norms; (f) illustrating clinical applications.

Method: Confirmatory factor analyses (CFAs) of parent, teacher, and self-ratings, performed separately for each society; tests of societal, gender, and age effects on dimensional syndrome scales, DSM-oriented scales, Internalizing, Externalizing, and Total Problems scales; tests of agreement between low, medium, and high ratings of problem items across societies.

Results: CFAs supported the tested syndrome models in all societies according to the primary fit index (Root Mean Square Error of Approximation [RMSEA]), but less consistently according to other indices; effect sizes were small-to-medium for societal differences in scale scores, but very small for gender, age, and interactions with society; items received similarly low, medium, or high ratings in different societies; problem scores from 44 societies fit three sets of multisociety norms.

The paper presents the results of the population structure research on the inhabitants of the Island of Rab by the analysis of anthropometric, continuous characteristics (morphological variables of head and body) on the representative sample of 601 adult persons (aged 18-75 years) from the settlements Banjol, Barbat, Lopar, Rab and Supetarska Draga (Figure 1). The aim was to investigate the possibility to confirm the existence of population groupings or divisions in one geographically limited area based on the analysis of continuous anthropometric variables. In other words, the purpose is to investigate the structure of the inhabitants in order to contribute to the explanation of its microevolution.

Metabolic syndrome (MS), a constellation of metabolic risk factors associated with development of cardiovascular diseases and Type 2 diabetes (T2D), has emerged as a public health problem of enormous proportions in developed and developing countries. We have reported previously its prevalence in several island populations of the Eastern Adriatic coast of Croatia. In spite of leading a relatively traditional life style pattern including adherence to a Mediterranean diet, the prevalence of MS in these populations is high and comparable to that in developed nations.

In a cross-sectional study of growth, 5,260 healthy children of both sexes from Zagreb (Croatia) aged 2 to 18 years were measured. Six transversal body dimensions were studied: biacromial, transverse chest, antero-posterior chest, biiliocristal, bicondylar humerus and bicondylar femur diamters. A significant increase in body diameters has been observed until the age of 14 to 15 in girls and until the age of 16 in boys, showing that girls have a 1 to 2 years shorter period of growth.

Anthropometric examinations have been carried out since 1901 (USA) with the aim of developing and furthering the garment and footwear size system. The contribution to the solution of these problems was noticed in the last decades when a technical board was founded and the propositions in ISO norm series as well as in European norm (EN) series were prescribed. Two methods are employed in anthropometric measurements: the conventional one using anthropometric instruments and the one applying a 3D body scanner.

The aim of the study was to investigate the antiproliferative, antiangiogenic and apoptotic effect of photochemotherapy (PUVA) in psoriatic patients, and to compare it with a control group of psoriatics treated with local corticosteroid therapy. The study included 60 psoriasis patients, 30 of them allocated to PUVA therapy and local corticosteroid each. Immunohistochemical methods of staining with Ki-67, F-8 and bcl-2 antibodies were used to determine proliferative keratinocyte count, to visualize the number of blood vessels in the dermis, and to determine the number of cells exhibiting expression of the antiapoptotic oncoprotein bcl-2, respectively.

This work points to the relevance of regional and state systems of garment sizes. High quality, garment size systems, garment design and economy are currently the focal points, which belie the outdated strategy of competitiveness based on product cost. The average body dimensions have considerably changed in the last decades.

The complexity of interactions between hereditary, environmental and cultural factors in determining human phenotypes is often underestimated in biomedical research. In this paper, we present 33 years of holistic anthropological research that was being conducted since 1971 in the island of Hvar, Croatia. During this period, detailed characterization of migrations, demography, isonymy, linguistic differences, anthropometric traits (head and body dimensions), physiological (cardio-respiratory) properties, quantitative and qualitative dermatoglyphic traits, radiogrammetric metacarpal bone dimensions and genetic traits (classical antigens, HLA diversity, DNA short tandem repeat -STR, mitochondrial DNA and Y-chromosome polymorphisms) was performed.

The determination and promotion of the system of shoe sizing requires accurate knowledge of morphological properties of the foot and lower leg of the tested population. Similarly it is necessary to establish the occurrence and regional distribution of definite sizes in the tested population. Possible regional differences in morphological properties must not be ignored because it has been established by means of anthropological measuring that both foot dimensions and foot shapes differ between populations and within the same population.
