The study presents data from ultrasound examination of patients skin in dynamics before and after exposure to the monopolar radio frequency method. There were 41 patients aged 38 to 45 years under observation, who were divided into 2 groups: with deformed and fine-wrinkled skin types. In all groups, a single exposure was performed using the monopolar radio frequency method on the Thermage device according to the approved Protocol of operation in the face area of 1200 pulses. Objective research methods included ultrasound diagnostics before treatment, 1, 3 and 6 months after treatment. It also determined the Dermatological Quality of Life Index. The results were evaluated 1, 3 and 6 months after the treatment. The obtained data of ultrasound examination of the skin showed that the best changes in the dermis high-frequency radio wave method gave a more pronounced initial thickness of the dermis and was more effective in the deformation type of skin aging compared to fine wrinkles.

The study presents data on the impact of the monopolar radiofrequency method on the morphofunctional state of the skin. Patients were observed with various morphotypes of involute skin changes. 49 patients aged 45 to 55 years were observed. All patients were divided into 3 groups depending on the prevailing morphotype of involute skin changes: fine-wrinkled, deformed, and mixed. In all groups, a single exposure was performed using the monopolar radio frequency method according to the approved Protocol of work in the face area. Objective research methods included ultrasound sonography of the epidermis and dermis, adapted dermatological indices of quality of life (DIQ) and SAN (well-being, activity, mood). The results were evaluated 3, 6 and 12 months after the treatment. The obtained data showed that the high-frequency radio-wave method is more effective in deformational and mixed types of aging compared to small-scale wrinkling.

Facial skin aging has been in the sphere of human interest since the earliest times, but relatively recently, along with the new branch of medicine — aesthetics there have appeared opportunities both for its slowing down and the instrumental study of the process. Recently, the emphasis is on the use of autologous preparations, especially on the basis of the own blood, among which the promising procedure seems to be CGF Harmony (stem cells labeled with CD34+ antigen and concentrated growth factors). The aim of this paper was to assess both subjective and objectified matured facial skin before and after CGF Harmony administrations, based on medical photographic documentation (the Fotomedicus system) and instrumental examination of skin parameters (Cutometer Dual MPA 580). The presented results show high variability and dynamics of obtained values. At the same time, they suggest a sustained improvement in the visual correction of the face oval and flattening of wrinkles, perceived positively by both the patient and her surroundings, and amelioration visible in photographic and instrumental studies in terms of skin elasticity (parameters R2 and R7). From the research and the manufacturer's proposal, it appears that one should suggest treatments in a semi‑annual cycle preceded by facial skin examinations.

Some of the brain areas in the ventral temporal lobe, such as the fusiform face area (FFA), are critical for face perception in humans, but what determines this specialization is a matter of debate. The face specificity hypothesis claims that faces are processed in a domain-specific way. Alternatively, the expertise hypothesis states that the FFA is specialized in processing objects of expertise. To disentangle these views, some previous experiments used an artificial class of novel objects called Greebles. These experiments combined a learning and fMRI paradigm. Given the high impact of the results in the literature, we replicated and further investigated this paradigm. In our experiment, eight participants were trained for ten 1-hr sessions at identifying Greebles. We scanned participants before and after training and examined responses in FFA and lateral occipital complex. Most importantly and in contrast to previous reports, we found a neural inversion effect for Greebles before training. This result suggests that people process the “novel” Greebles as faces, even before training. This prediction was confirmed in a postexperimental debriefing. In addition, we did not find an increase of the inversion effect for Greebles in the FFA after training. This indicates that the activity in the FFA for Greebles does not depend on the degree of expertise acquired with the objects but on the interpretation of the stimuli as face-related.

Today is the era of Cloud Computing Technology in IT Industries. Cloud computing which is based on Internet has the most powerful architecture of computation. It reckons in of a compilation of integrated and networked hardware, software and internet infrastructure. It has various avails atop grid computing and other computing. In this paper, I have given a brief of evaluation of cloud computing by reviewing more than 30 articles on cloud computing. The outcome of this review signalizes the face of the IT industries before and after the cloud computing.

The following article analyzes the effectiveness of directional hydraulic fracturing (DHF) as a method of rock burst prevention, used in black coal mining with a longwall system. In order to define changes in seismic activity due to DHF at the “Rydułtowy” Black Coal Mine (Upper Silesia, Poland), observations were made regarding the seismic activity of the rock mass during coal mining with a longwall system using roof layers collapse. The seismic activity was recorded in the area of the longwall itself, where, on a part of the runway, the rock mass was expanded before the face of the wall by interrupting the continuity of the rock layers using DHF. The following article presents measurements in the form of the number and the shock energy in the area of the observed longwall, which took place before and after the use of DHF. The second part of the article unveils the results of numerical modeling using the discrete element method, allowing to track the formation of goafs for the variant that does not take DHF into consideration, as well as with modeled fractures tracing DHF carried out in accordance with the technology used at “Rydułtowy” coal mine.

An increase in labor productivity and a reduction of fuel consumption rates were two notable and closely related achievements of the management of Hopewell Forge, an ironworks in eighteenth-century Pennsylvania. Significantly, these economies were realized in the face of technological stasis through learning by doing. The analysis of this accomplishment is cast in the larger context of the performance of the iron industry before and after 1800.

In this paper, we proposed an efficient method to address the problem of color face image segmentation that is based on color information and saliency map. This method consists of three stages. At first, skin colored regions is detected using a Bayesian model of the human skin color. Then, we get a chroma chart that shows likelihoods of skin colors. This chroma chart is further segmented into skin region that satisfy the homogeneity property of the human skin. The third stage, visual attention model are employed to localize the face region according to the saliency map while the bottom-up approach utilizes both the intensity and color features maps from the test image. Experimental evaluation on test shows that the proposed method is capable of segmenting the face area quite effectively,at the same time, our methods shows good performance for subjects in both simple and complex backgrounds, as well as varying illumination conditions and skin color variances.
