Desenvolvimento Territorial e Turismo Rural: As Relações Possíveis
Authors: Kloster Silvana , Cunha Luiz Alexandre Gonçalves
Published: February 2017

O artigo trás reflexões teóricas sobre o desenvolvimento territorial e o turismo rural, fazendo a relação entre as partes e as suas perspectivas analógicas, levando-se em consideração os possíveis riscos e potencialidades da atividade. Está dividido em quatro partes: a primeira apresenta a formação territorial rural no Brasil e a dualidade do sistema agrário, a agricultura empresarial x agricultura familiar, que por muito tempo foi caracterizada como agricultura de subsistência. Na década de 1990, uma nova concepção sobre a agricultura familiar passa a ser concebida revalorizando o seu espaço criando novas formas de produção agrícola e não agrícola. A segunda parte aborda o turismo rural, como uma ação apropriada para os programas de desenvolvimento territorial, elencando as motivações dos turistas, o início da atividade e as principais tipologias A terceira faz a relação entre as duas partes anteriores relacionando o turismo rural com o desenvolvimento territorial rural e as suas possibilidades tendo como referencial teórico, a concepção e antagonismo de autores das áreas de Turismo e Geografia. A quarta parte trata especificamente das políticas públicas para o desenvolvimento da atividade de turismo onde é possível perceber que o turismo rural é tratado, nos planos nacionais e regionais, como mais um segmento da atividade. O capítulo discutirá a atividade turística e o estabelecimento de relações que podem causar diferentes impactos. A minimização dos impactos negativos é o grande desafio estudado por diferentes áreas do conhecimento.
Prediction of long-term creep deflection of seismic isolation bearings
Authors: Oh Ju , Kim Jin Ho
Published: February 2017

Isolation structures use high damping rubber bearings (HDRBs), lead rubber bearings (LRBs), and natural rubber bearings (NRBs) in order to significantly reduce the seismic forces transmitted from a substructure to a superstructure. The laminated rubber bearing is the most important structural member of a seismic isolation system. We present an analysis of a 1000 hr ongoing creep test conducted at 7.5 and 8.37 MPa in our laboratory. The long term behavior of bridge bearings (e.g., laminated rubber bearings) is determined through compression creep tests subjected to actual environmental conditions. These tests indicate that the maximum creep deformation is about 0.3 to 1.92 % of the total rubber thickness.
Wavelet support vector machine and multi-layer perceptron neural network with continues wavelet transform for fault diagnosis of gearboxes
Authors: Heidari Mohammad , Shateyi Stanford
Published: February 2017

In this paper, a method based on wavelet support vector machine (SVM) with OAOT algorithm, multi-layer perceptron (MLP) and Morlet wavelet transform were designed to diagnose different types of fault in a gearbox. A scale selection criterion based on the maximum relative energy to Shannon entropy ratio is proposed to determine optimal decomposition scale for wavelet analysis. Moreover, energy and entropy of the wavelet coefficients are used as two new features along with other statistical parameters as input of the classifier. The results showed that the WSVM identified the fault categories of gearbox more accurately as compared to the MLP network.

Acoustic calculation in low frequency sonopheresis based on bubble dynamics
Authors: Peng Hanmin , Lu Penghui , Zhu Pancheng , Yu Boping
Published: February 2017

As a type of transdermal permeability enhancement, low frequency sonophoresis (LFS) has been studied for more than twenty years. The acoustic pressure in LFS is a crucial ultrasonic parameter to improve the permeability, but it is difficult to measure in the drug donor because of its small size and narrow shape. In this paper, an acoustic-piezoelectric coupling model is established based on bubble dynamics, which can be utilized to calculate the acoustic pressure distributions in LFS using a commercial finite element software called COMSOL multiphysics. The calculated results of acoustic pressure are in accordance with the measured values, so this model has great potential for theoretical analyses in acoustic fields of LFS. Calculated and experimental results show that the maximum acoustic pressure is under the transducer’s head, and the value dropped as away from the head due to the acoustic attenuation caused by cavitation; the transducer head should be closer to the skin to obtain larger acoustic pressure on the skin. Therefore, this model can be used to simulate and analyze the characteristics of acoustic fields, as a theoretical tool for the structural design of the ultrasonic transducer applied in LFS.

Authors: Shen Linbang , Chu Zhigang , Yang Yang , Wang Guangjian
Published: February 2017

To eliminate the influence of the interference acoustic source behind the array on the source identification performance, some modifications on the traditional single-layer beamforming microphone array are made, a new array with acoustic insulation baffle in the microphone plane is given out to suppress the influence of interference acoustic source. Simulation and verification results show that, with the presence of the interference acoustic source in the rear of traditional planar array, the acoustic source position and amplitude deviations are larger and it indicates that the interference acoustic source seriously affects the identification performance of target acoustic source. Compared to the performance of traditional planar array, the new microphone array with acoustic insulation baffle can effectively eliminate the influence of interference acoustic source behind the array and improve the accuracy of the location and amplitude of the target acoustic source. The experiment verifies the correctness of the simulation conclusions and the applicability of the modified microphone array in the cabin of automotive and aircraft and other narrow space.

Authors: Fan Xiaobin , Zang Yong , Jin Ke , Wang Ping’an
Published: February 2017

According to the fluid mechanics and rolling theory, the rolling interface friction dynamic characteristics and their influence on rolling speed, rolling load, roller material, rolling temperature and oil properties were studied respectively with lubrication or without lubrication in hot rolling. The two-dimensional Reynolds equation was established for steady and unsteady rolling friction interface. Through the research of rolling interface friction characteristics influence on the mill vibration, we found that when the lubrication film thickness in the roll gap was thicker, the friction coefficient was lower, its damping effect and system stability was worse. And if the rolling speed is greater than a certain value, the rolling interface friction coefficient will fall sharply with the increase of rolling speed and produces the self-excited vibration caused by negative damping. So the contrast test with different rolling interface has been carried out, such as the emulsion is open or close, high chromium cast iron/high speed steel roller is put to use, high chromium cast iron roller is grinded finely or coarsely, rolling speed is normal/reduced. And the results showed that it had an obvious effect on the mill vibration suppression by the adoption of the emulsion close and high speed steel roller.

Authors: Hoseini Vaez Seyed Rohollah , Arefzade Tahere
Published: February 2017

This study has presented a method to estimate the damage location in the concrete gravity dam monolith. The first four vibration mode of the highest monolith of the Koyna dam was estimated and analyzed by the combined discrete and continuous wavelet transform. The position of the damage scenarios was identified by using bior 3.9 wavelet in the spatial variation of the data response. The sensitivity of wavelet to random signal noise was investigated by using noise to displacement response of cracked monolith. Three noise levels were introduced in the model and the capacity of this method to detect damage from noisy data was discussed.
A CFD study of IGV vane number on hydraulic characteristics and pressure pulsation of an is centrifugal pump
Authors: Hou Hucan , Zhang Yongxue , Li Zhenlin , Zhang Yuan
Published: February 2017

Vane number is an important parameter of IGV device, which indirectly affects hydraulic performance and pressure pulsation characteristics of the attached pump. In this study, based on an IS pump, the influences of vane number on hydraulic performance and pressure pulsation characteristics were considered. Four set of IGV devices were generated to assemble to the pump with 5, 6, 7 and 9 vanes, respectively. Then the three-dimensional unsteady flow fields were simulated using RNG k-ε turbulence model and sliding mesh by Fluent-16.0. The numerical results showed good agreement with the experimental data, which validated the numerical models. The effects of vane number on pump head and efficiency are different. 6 vanes IGV device can produce higher head while 7 or 9 vanes can bring about higher efficiency. Similarly, the influences of vane number on pressure pulsation in time domain and frequency domain are also complex. 6 vanes IGV device can remarkably decrease power spectral density at all flow rate conditions, but 7 vanes IGV device can improve pump pressure pulsation characteristics and realize better hydraulic stability. Therefore, it is hard to determine the best vane number, but 6 vanes IGV device is suggested for engineering application to obtain better hydraulic performance.
A study on Gabor frame for estimating instantaneous dynamic characteristics of structures
Authors: Su Wei-Chih , Huang Chiung-Shiann
Published: February 2017

A structure under damage normally exhibits nonlinear dynamic behaviors and time-dependent stiffness and damping. By estimating instantaneous dynamic characteristics of a structures is generally very useful when assessing structural damage in real application. This study presents a novel and effective approach that accurately estimating instantaneous dynamic characteristic of a structure using time-varying autoregressive exogenous (TVARX) model on Gabor frame. To evaluate the time-varying coefficient matrices of a time-series model, the proposed procedure applies Gaussian-based weighted function and Fourier transform on time series model, then the Gabor-transform-based time series formula could be obtained. The dynamic characteristics of a structure are determined from the coefficient matrices. Numerical analyses demonstrate that the proposed approach is superior to traditional time-frequency analysis in accurately estimating instantaneous dynamic characteristics of a structure. Finally, the proposed approach is applied to process measured data for a steel frame specimen subjected to a series of base excitations in shaking table tests.
Nonlinear dynamic modeling and fuzzy sliding-mode controlling of electromagnetic levitation system of low-speed maglev train
Authors: Sun Yougang , Li Wanli , Xu Junqi , Qiang Haiyan , Chen Chen
Published: February 2017

The electromagnet levitation system (ELS) of low-speed maglev train is taken as the research object. The nonlinear dynamics and control law of ELS are discussed. Specifically, by employing the Euler-Lagrange’s method, a nonlinear dynamic model is constructed for the single-ELS. Then, the linear control law is studied, which has a disadvantage of weak robustness. To improve the performance of the controller, a fuzzy sliding-mode control law is proposed. According to the dynamic nonlinear model, a novel sliding surface which can make the system reach the stable point within the finite time is presented. Moreover, the fuzzy inference method is utilized to slow down the speed of the states crossing the sliding surface. The simulation results demonstrate that the global robustness of external disturbance and parameter perturbation can be achieved through the proposed control law. And the chattering phenomenon can be reduced significantly. Finally, the experiments are also implemented to examine its practical dynamic performance of the proposed control law.
Modeling of chromium (VI) adsorption from aqueous solutions using Jordanian Zeolitic Tuff
Authors: Al Dwairi Reyad
Published: February 2017

The probable use of Jordanian natural zeolitic tuff in wastewater treatment as natural adsorbent for the removal of Cr (VI) ions from aqueous solution in continuous fixed bed columns was tested experimentally and theoretically. The tested zeolitic tuff was obtained from Al Hala volcano (HZ) located in southern part of Jordan and subjected to crushing and sieving only without any further treatment. Experimentally the HZ grains were packed in a fixed bed column. The used grain sizes are HZ1 (1.0–0.60 mm) and HZ2 (0.60–0.30 mm). The adsorption capacity was evaluated using breakthrough curves and by applying the Thomas and Yoon and Nelson models. The Thomas model analysis of the measured breakthrough curves revealed that the adsorbent HZ2 has a higher adsorption capacity to Cr (VI) ions (56.3 mg/g) than HZ1 (35.5 mg/g). The time elapsed to reach 50% breakthrough was determined by the Yoon and Nelson model. The time to reach 50% breakthrough is 318.78 min and 368.18 min for HZ1 and HZ2, respectively. The research results indicate that the small size fraction (HZ2) is more suitable and effective as adsorbent material than the size fraction (HZ1) due to its high surface area.

Published: February 2017

A sustentabilidade deverá ser entendida tomando-se por base os aspectos ecológico, econômico e social. A partir da década de 80, do século XX, os efeitos do neoliberalismo e da revolução informacional provocaram metamorfoses no mundo do trabalho. Inicia-se um processo de precarização envolvendo escassez de postos de trabalho. De lá para cá esse processo devastador parece não ter freios com tendências para que o negociado prevaleça sobre do legislado. O momento requer uma ressignificação da igualdade entre os atores sociais no processo negocial coletivo para todos que desejam viver a partir do trabalho.

Published: February 2017

Background and objectives

Elevated serum triglyceride/HDL cholesterol (TG/HDL-C) ratio has been identified as a risk factor for cardiovascular (CV) disease and mortality in the general population. However, the association of this important clinical index with mortality has not been fully evaluated in patients with ESRD on maintenance hemodialysis (MHD). We hypothesized that the association of serum TG/HDL-C ratio with all-cause and CV mortality in patients with ESRD on MHD is different from the general population.

Design, setting, participants, & measurements

We studied the association of serum TG/HDL-C ratio with all-cause and CV mortality in a nationally representative cohort of 50,673 patients on incident hemodialysis between January 1, 2007 and December 31, 2011. Association of baseline and time-varying TG/HDL-C ratios with mortality was assessed using Cox proportional hazard regression models, with adjustment for multiple variables, including statin therapy.

Results

During the median follow-up of 19 months (interquartile range, 11–32 months), 12,778 all-cause deaths and 4541 CV deaths occurred, respectively. We found that the 10th decile group (reference: sixth deciles of TG/HDL-C ratios) had significantly lower risk of all-cause mortality (hazard ratio, 0.91 [95% confidence interval, 0.83 to 0.99] in baseline and 0.86 [95% confidence interval, 0.79 to 0.94] in time-varying models) and CV mortality (hazard ratio, 0.83 [95% confidence interval, 0.72 to 0.96] in baseline and 0.77 [95% confidence interval, 0.66 to 0.90] in time-varying models). These associations remained consistent and significant across various subgroups.

Conclusions

Contrary to the general population, elevated TG/HDL-C ratio was associated with better CV and overall survival in patients on hemodialysis. Our findings provide further support that the nature of CV disease and mortality in patients with ESRD is unique and distinct from other patient populations. Hence, it is vital that future studies focus on identifying risk factors unique to patients on MHD and decipher the underlying mechanisms responsible for poor outcomes in patients with ESRD.

Let G be a (p, q)-graph in which the edges are labeled 1, 2, . . . , q. The vertex sum for a vertex v is the sum of the labels of the incident edges at v. If the vertex sums are constant, modulo k, where k>= 2, then G is said to be Mod(k)-edge-magic. When k = p, Mod(p)-edge-magic graph is the edge-magic graph which was introduced by the Lee, Seah and Tan in [9]. In this paper we investigate graphs which are Mod(3)-edge-magic.DOI : http://dx.doi.org/10.22342/jims.0.0.81.

The genes on each chromosome are subject to unbiased andreciprocal gene conversion and mutation. Using the coalescent approach we find theprobability distribution of the allelic configurations in the three chromosomes, andthe moments of the allelic numbers that exist in one of the three chromosomes orin a pair of chromosomes. We also consider the identity coefficients of two genesdrawn at random, one from each of two chromosomes, and the probability that allgenes in the three chromosomes are monomorphic.

For the proof of the result we apply the uniform central limittheorem of Alexander and Pyke (1986) and generalize the geometrical approach ofBischo (2002) and Bischo and Somayasa (2009). It is shown that the limit processis a projection of the set-indexed Brownian sheet onto the reproducing kernel Hilbertspace of this process.

Published: February 2017

Weak local residual (WLR) detects the smoothness of numerical solutionsto conservation laws. In this paper we consider balance laws with a sourceterm, the shallow water equations (SWE). WLR is used as the reﬁnement indicatorin an adaptive ﬁnite volume method for solving SWE. This is the ﬁrst studyin implementing WLR into an adaptive ﬁnite volume method used to solve theSWE, where the adaptivity is with respect to its mesh or computational grids. Welimit our presentation to one-dimensional domain. Numerical simulations show theeﬀectiveness of WLR as the reﬁnement indicator in the adaptive method.DOI : http://dx.doi.org/10.22342/jims.20.1.176.11-18
A WHITE NOISE APPROACH TO THE SELF-INTERSECTION LOCAL TIMES OF A GAUSSIAN PROCESS
Authors: Suryawan Herry Pribawanto
Published: February 2017

In this paper we show that for any spatial dimension the renormalized self-intersection local times of a certain Gaussian process defined by indefinite Wiener integral exist as Hida distributions. An explicit expression for the chaos decomposition in terms of Wick tensor powers of white noise is also obtained. We also study a regularization of the self-intersection local times and prove a convergence result in the space of Hida distributions.DOI : http://dx.doi.org/10.22342/jims.20.2.136.111-124

ON FREE IDEALS IN FREE ALGEBRAS OVER A COMMUTATIVE RING
Authors: Wardati Khurul , Wijayanti Indah Emilia , Wahyuni Sri
Published: February 2017

Let A be a free R-algebra where R is a unital commutative ring. An ideal I in A is called a free ideal if it is a free R-submodule with the basis contained in the basis of A. The denition of free ideal and basic ideal in the free R-algebra are equivalent. The free ideal notion plays an important role in the proof of some special properties of a basic ideal that can characterize the free R-algebra. For example, a free R-algebra A is basically semisimple if and only if it is a direct sum of minimal basic ideals in A: In this work, we study the properties of basically semisimple free R-algebras.DOI : http://dx.doi.org/10.22342/jims.21.1.170.59-69
TWO ASPECTS OF A GENERALIZED FIBONACCI SEQUENCE
Authors: Tuwankotta Johan Matheus
Published: February 2017

In this paper we study the so-called generalized Fibonacci sequence: $x_{n+2} = \alpha x_{n+1} + \beta x_n, n\in \mathbb{N}$.  We derive an open domain around the origin of the parameter space where the sequence converges to $0$.  The limiting behavior on the boundary of this domain are: convergence to a nontrivial limit, $k$-periodic ($k\in \mathbb{N}$), or quasi-periodic.  We use the ratio of two consecutive terms of the sequence to construct a rational approximation for algebraic numbers of the form: $\sqrt{r}, r\in \mathbb{Q}$.  Using a similar idea, we extend this to higher dimension to construct a rational approximation for  $\sqrt[3]{ a + b\sqrt{c}} +  \sqrt[3]{ a - b\sqrt{c}} + d$.DOI : http://dx.doi.org/10.22342/jims.21.1.173.1-17
NUMERICAL ENTROPY PRODUCTION OF THE ONE-AND-A-HALF-DIMENSIONAL SHALLOW WATER EQUATIONS WITH TOPOGRAPHY
Authors: Mungkasi Sudi
Published: February 2017

Numerical entropy production can be used as a smoothness indicator of solutions to conservation laws. By definition the entropy production is non-positive. However some authors, using a finite volume method framework, showed that positive overshoots of the numerical entropy production were possible for conservation laws (no source terms involved). Note that the one-and-a-half-dimensional shallow water equations without source terms are conservation laws. A report has been published regarding the behaviour of the numerical entropy production of the one-and-a-half-dimensional shallow water equations without source terms. The main result of that report was that positive overshoots of the numerical entropy production were avoided by use of a modified entropy flux which satisfies a discrete numerical entropy inequality. In the present article we consider an extension problem of the previous report. We take the one-and-a-half-dimensional shallow water equations involving topography. The topography is a source term in the considered system of equations. Our results confirm that a modified entropy flux which satisfies a discrete numerical entropy inequality is indeed required to have no positive overshoots of the entropy production.DOI : http://dx.doi.org/10.22342/jims.21.1.198.35-43

Authors: Yuwaningsih Dian Ariesta , Wijayanti Indah Emilia
Published: February 2017

Let $M$ be an $(R,S)$-module. In this paper a generalization of the m-system set of modules to $(R,S)$-modules is given. Then for an $(R,S)$-submodule $N$ of $M$, we define $\sqrt[(R,S)]{N}$ as the set of $a\in M$ such that every m-system containing $a$ meets $N$. It is shown that $\sqrt[(R,S)]{N}$ is the intersection of all jointly prime $(R,S)$-submodules of $M$ containing $N$. We define jointly prime radicals of an $(R,S)$-module $M$ as $rad_{(R,S)}(M)=\sqrt[(R,S)]{0}$. Then we present some properties of jointly prime radicals of an $(R,S)$-module.DOI : http://dx.doi.org/10.22342/jims.21.1.199.25-34

SIMULATION OF ANALYTICAL TRANSIENT WAVE DUE TO DOWNWARD BOTTOM THRUST
Authors: Tjandra Sugih Sudharma , Pudjaprasetya Sri Redjeki , Wiryanto Leo Hari
Published: February 2017

Generation process is an important part of understanding waves, especially tsunami. Large earthquake under the sea is one major cause of tsunamis. The sea surface deforms as a response from the sea bottom motion caused by the earthquake. Analytical description of surface wave generated by bottom motion can be obtained from the linearized dispersive model. For a bottom motion in the form of a downward motion, the result is expressed in terms of improper integral. Here, we focus on analyzing the convergence of this integral, and then the improper integral is approximated into a finite integral so that the integral can be evaluated numerically. Further, we simulate free surface elevation for three different type of bottom motions, classified as impulsive, intermediate, and slow  movements. We demonstrate that the wave propagating to the right, with a depression as the leading wave, followed with subsequent wave crests. This phenomena is often observed in most tsunami events.DOI : http://dx.doi.org/10.22342/jims.21.2.189.93-104

FOUNDATIONS OF ORDERED (SEMI)HYPERRINGS
Authors: Davvaz Bijan , Omidi S.
Published: February 2017

In this paper, we introduce the notion of general hyperring $(R,+,\cdot)$ besides a binary relation $\le $, where $\le $ is a partial order such that satisfies the conditions: (1) If $a \le b$, then $a+c \le b+c$, meaning that for any $x \in a+c$, there exists $y \in b+c$ such that $x\le y$. The case $c+a\le c+b$ is defined similarly. (2) If $a \le b$ and $c \in R$, then $a\cdot c \le b\cdot c$, meaning that for any $x\in a\cdot c$, there exists $y\in b\cdot c$ such that $x\le y$. The case $c\cdot a \le c\cdot b$ is defined similarly. This structure is called an ordered general hyperring. Also, we present several examples of ordered general hyperrings and prove some results in this respect. By using the notion of pseudoorder on an ordered general hyperring $(R,+,\cdot,\le)$, we obtain an ordered ring. Moreover, we study some properties of pseudoorder on an ordered general hyperring.DOI : http://dx.doi.org/10.22342/jims.22.2.233.131-150

Published: February 2017

Introduction. A single coronary artery (SCA) is defined as a coronary artery that arises from the sinus of Valsalva and supplies the entire heart. This is a rare congenital anomaly occurring in approximately 0.04?0.13% of the population. SCA can be diagnosed during life by coronary angiography and multislice cardiac computed tomography. There are many anatomical variations of single coronary arteries. Case outline. A 50-year-old man presented with acute ST elevation myocardial infarction (STEMI). Coronary angiography revealed the case of an SCA with left anterior descending artery and circumflex artery arising separately from the right coronary artery which was occluded proximally to their taking-off. Successful primary percutaneous coronary intervention was performed and is reported here in details. This is the first described case of an SCA (classified as R-III and R-III-C by Lipton and Yamanaka, respectively) with a clinical presentation as STEMI. A description of the undertaken management is also provided. Conclusion. Coronary artery anomalies require accurate recognition in order to help cardiologists plan appropriate management of these patients.

Published: February 2017

Clostridium difficile (CD) is the most common cause of nosocomial diarrhea in adults with high rates of morbidity and mortality. The epidemiology of CD infection (CDI) has changed in the last few decades associated with increasing severity of the infection rate related to the occurrence of NAP1 hypervirulent strain and the emergence of the disease among ambulatory patients and the wider community. Although little is known about CDI in pediatric patients, CD is surprisingly recognized as an important pathogen in children. In this review article, we direct attention to the recent findings on the incidence and epidemiology of pediatric CDI, including the risk factors for infection, with special emphasis on the importance of CDI in infants and a population of children suffering from chronic gastrointestinal diseases or cancer. Despite recent pharmacotherapeutic protocols successfully used in children with CDI, we would like to draw attention to precautionary and preventive measures in terms of both unnecessary testing and uncritical use of antibiotics as the most important risk factors.

Published: February 2017

Background/Aim. Depersonalization is considered to be the third leading symptom in psychiatric morbidity. The aim of this study was to investigate the correlation of depersonalization and different patterns of suicidal behaviour in patients suffering from depresssive disorder. Methods. The study included 119 depressed patients divided into two groups: the first group consisted of depressed patients with clinically manifested depersonalization according to the Cambridge Depresonalisation Scale presented score ? 70, and the second group consisted of the patients whithout clinically manifested depersonalization symptomatology, or, it was on the subsyndromal level. Subsequently, these two groups were compared regarding the suicidality indicators. Results. According to the Scale for Suicide Ideation of Beck, the depressed patients with depersonalization had statistically significantly higher scores regarding suicidal ideation, both active and passive, more often manifested suicidal desire, suicidal planning and overall suicidality (p < 0.000). Positive ideation, as a protective factor, was reduced in this group (p < 0.000). These patients had more previous suicide attempts (p < 0.001) and family history of suicides (p = 0.004). The depressed patients with depersonalization had 8 times more often active suicidal desire, 11 times more often passive suicidal desire and 5 times more often suicidal planning compared to patients without depersonalization. Conclusion. Suicidal potential, manifested in various patterns of suicidal behaviour among the patients suffering from depressive disorder with clinically manifested depersonalization is prominent. It is necessary to pay particular attention to depersonalization level during diagnostic and treatment procedure of the depressed patients having in mind that it may be associated with high suicidal potential.
