The hiddenness of God is a new challenge in the philosophy of religion. In short, the believers of this view say that if there is a god, he should not hide himself from the eyes of humans and should be clear in such a way that humans can communicate with him. If God exists and guides mankind, why hasn't He hidden Himself from the eyes of humans or at least given more signs of His presence to humans? Is it not possible for us to have more proofs of the existence and presence of God as well as the truth of religious propositions so that no one can claim that he has sought to find the truth of religion and has not succeeded? Couldn't it be possible for us to have options such as seeing purgatory, communication with the souls after death, and talking with religious leaders in a wider way than now, so that our religious doubts disappear and our certainty increases? How can "divine CONCEALMENT" be combined with his guidance? Is it possible to combine the two and not fall into the trap of conflict? In this article, the conflict between God's guidance and His disappearance is examined in a descriptive and analytical way, and to solve the problem of His disappearance, His guidance is interpreted as "necessary" and "possible".

Architecture in every society is influenced by the norms and values of that society. Iranian architecture is no exception to this rule and has evolved throughout its several thousand years of history in connection with Iranian culture and ways of life. Introversion and CONCEALMENT in architecture, as well as the separation of interior and exterior in traditional houses, is one of the prominent features of Iranian architecture. In this article, we have discussed the relationship of this architectural manifestation with the social ethics of Iranians in the Qajar period and we are looking for the common roots of the dual inside and outside in Iranian architecture and personality in Iran's social conditions. The research method in this article is a historical interpretation based on the data obtained from the travelogues of European tourists. The findings of the research show that the social insecurity in the society, which itself was the result of factors such as authoritarian and arbitrary government methods, has been an effective factor in the formation of this spirit in people and subsequently in houses and other buildings, and this is due to the background The cultural values of Iranians have emerged in specific ways.

Patients deliberate CONCEALMENT from others of the content and Frequency of their obsessions is a common and important aspect of obsessive compulsive disorder (QCD). It is an overlooked manifestation of the safety behaviour that is believed to sustain QCD (e.g., neutralizing, thought suppression, avoidance behaviour, CONCEALMENT). The phenomenon of CONCEALMENT is understandable in terms of the cognitive theory of obsessions which states that obsessions are caused when the person attaches catastrophic personal significance to their unwanted intrusive thoughts. It is suggested that the selected, planned, suitable disclosure of obsessions can be therapeutic presumably because it exposes the patient to alternative interpretations of the significance of the unwanted thoughts.

The crimes of kidnapping and CONCEALMENT constitute two examples of crimes against persons which in addition to depriving freedom and inflicting physical harm on the victim, violate the victim’s personality. One article of Islamic Penal Law deals specifically with the crimes while several articles have a general relation thereto, and ample regulations can be found in Iranian Criminal Law arsenal which bear on the crime. But the crime has drawn little attention in legal literature. So, the paper attempts to examine general and specific elements of the two crimes, pointing to the present state of Laws and regulations in order to determine the abrogating and the abrogated or general and special among them. This takes a large section of the paper, since there exist many ambiguities in the field which require critical examination. Also dealt with are issues such as jurisprudential viewpoints, the relationship of the crimes with similar crimes like arbitrary detention, factors aggravating penalty, attempt to commit the crimes and suspension of sentence.

Background and Objective: Disclosure of disease is one of the most complex challenges for individuals who live with thalassemia. This issue is associated with being stigmatized. It is usually associated with anxiety, fear, and negative reactions of other people. Exploring the experience of CONCEALMENT resulting from thalassemia-related stigma and designing effective interventions is the key to effective treatment and caring of these patients. The present study was conducted to explain the experiences of thalassemia patients and their caregivers concerning disease CONCEALMENT due to stigmatization.Materials and Method: This qualitative study performed through conventional content analysis approach. The 21 participants with major thalassemia and their caregivers were selected through purposive sampling. The research was performed in the medical facility of Samen Alhojaj, Kerman, Iran, during 2012-2013. Data were gathered through unstructured interviews and field notes. Data analysis was done using conventional content analysis approach.Results: The concept of CONCEALMENT experienced by patients and their caregivers included the reasons for CONCEALMENT (disease as a barrier for goal achievement, patient’s personal traits as a barrier for disease disclosure, parents tendency for disease CONCEALMENT, wrong behaviors and beliefs of the society due to stigmatization of the disease), strategies for CONCEALMENT (secret caring and lying), and CONCEALMENT outcomes (physical exhaustion, mental stress, deprivation of support).Conclusion: Patients’ experiences related to thalassemia stigmatization indicated that these patients not only experience adverse physical and mental outcomes of the disease, but also deal with the disease CONCEALMENT resulting from social stigmatization. The results of the current study can be an introduction to planning interventions to resolve social problems of these patients and help promote their quality of life.

Given the essential role of individual trenches in the survival and mission accomplishment of insider forces, especially in the plains, it is obvious that the enemy uses a variety of aerial and space sensors for their detection and identification. Imaging cameras are one of the main systems for detecting targets, especially at night. The main agent that causes the detection of a trench in thermal images is the thermal anomaly in its opening with respect to the surrounding environment. This study intends to use field observations and visual assessment methods to investigate the possibility of identifying fighters stationed in foxhole trenches and to provide measures and considerations to prevent the detection of foxhole trenches in plain areas. For this purpose, 36 scenarios in different positions namely: person standing next to the trench, person standing in the trench and person sitting in the trench, two different times, bright and dark days at different distances, are considered. Based on the experimental results obtained, it is possible to detect foxhole trenches without camouflage in plain areas at close range. Also, the best type of camouflage is the use of dry and lifeless plants related to the area.

A challenging aspect of video error CONCEALMENT (VEC) is reducing blockiness around the missing region. In this paper, we have devised a novel method for calculating the boundary matching distortion based on the edge direction surrounding the lost area to deal with this problem. After detecting the corresponding slice’s erroneous Macroblock (MB), it is divided into four 8×8 pixels sub-blocks. Then, the gradient of outer boundary pixels is derived and determines each side’s smoothness, which is further used for drawing the hypothetical line. Furthermore, this paper proposes a novel optimization-based model that can accurately measure boundary matching error for loss recovery. We observe better results for our proposed technique than other related VEC algorithms in terms of PSNR and SSIM. The proposed algorithm improves the average PSNR by 1.09 dB and increases the average SSIM by 0.0135 at the packet loss rate of 10%. In addition, for a PLR of 20%, the PSNR is increased by 1.28 dB, and the SSIM enhancement is 0.019. This algorithm is slightly more computationally complex than the compared methods, but it is still acceptable. Thus, by adding a few computations to the video decoder, the proposed method maintains the quality of the video, especially in the rough, damaged regions of a decoded frame.

Motion-JPEG is a common video format for compression of motion images with high quality using JPEG standard for each frame of the video. During transmission through a noisy channel some blocks of data are lost or corrupted, and the quality of decompression frames decreased. In this paper, for reconstruction of these blocks, several temporal-domain, spatial-domain, and frequency-domain error CONCEALMENT methods are investigated. Then a novel method is proposed for recovery of channel errors with a mixture of temporal-domain and frequency-domain error CONCEALMENT methods. To reconstruct the missed blocks in the proposed novel method, when two successive frames are similar, a proposed two phase block matching algorithm is performed in temporal-domain. When two successive frames are different, our proposed method reconstructs the missed block by the estimation of DC and AC coefficient, in frequency-domain. The proposed method and the other similar methods are simulated for different noise and quality factors. The results of quality measurements are indicated that in all tested video sequences, the proposed method shows higher quality in reconstruction of missed blocks.
