<h2>Data security has become a paramount necessity and more obligation in daily life. Most of our systems can be hacked, and it causes very high risks to our confidential files inside the systems. Therefore, for various security reasons, we use various methods to save as much as possible on this data, regardless of its different forms, texts, pictures, videos, etc. In this paper, we mainly rely on storing the basic image which should be protected in another image after changing its formal to composites using the DWT wavelet transform. The process of zeroing sites and storing their contents technique is used to carry the components of the main image. Then process them mathematically by using the exponential function. The result of this process is to obtain a fully encrypted image. The image required to be protected from detection and discrimination is hidden behind the encrypted image. The proposed system contains two algorithms. the first algorithm is used for encryption and hiding, but the second algorithm is designed for returning and decoding the main image to its original state with very efficiently.</h2>

Masyarakat Orang Asli Temiar merupakan komuniti orang yang telah lama wujud di negara kita.Kepelbagaian nilai budaya kehidupan masyarakat menjadi lambang jati diri dan kebanggaan masyarakatini. Oleh sebab itu, masyarakat Orang Asli Temiar ini sememangnya kaya dengan warisan ceritarakyat yang menjadi kebanggaan kepada masyarakat tersebut. Namun demikian, arus kepesatan,pembangunan dan kemajuan kemodenan menyebabkan khazanah cerita rakyat ini semakin dipinggirkanoleh masyarakat ini. Selain itu, mereka beranggapan bahawa medium lisan sebagai cerita mitos yangbercorak dongeng dan sekadar untuk berhibur semata-mata. Menerusi kajian ini, akan membincangkansatu objektif utama iaitu menganalisis nilai budaya dalam cerita rakyat masyarakat Orang Asli Temiar GuaMusang, Kelantan. Hal ini, dengan sendiri mewujudkan ruang ilmiah yang menuntut kepada pengkajianilmiah yang khusus. Sehubungan itu, pengkaji akan menggunakan kaedah kepustakaan dan kaedahkajian lapangan bagi memastikan kelancaran dalam menjalankan kajian tersebut.

An interesting prospective pseudomorphic overlayer on bcc surface material as implemented in Pd pseudomorphic overlayer on V(110) surface has been introduced in the frame work of first-principles calculation. Adsorption and decomposition of H2S molecule were calculated on this overlayer structure. In comparison, we also calculated them on their bare V(110) and Pd(111) surfaces. It was found that Pseudomorphic overlayer surface structure weakened the adsorption energy of H2S, SH, S and H compared to its bare Pd(111) and V(110) surfaces. Furthermore, Pd/V(110) surface was found to have higher activation energy barrier for H2S and SH dissociation than its bare Pd(111) and V(110) do. Pd/V(110) surface is predicted to be a promising catalyst membrane used in gas-shift reactor technology because besides its advantage to absorb hydrogen with very high permeation coefficient, sulfur atom is predicted to be adsorbed in a limited amount.

Steganography is one of the most important tools in the data security field as there is a huge amount of data transferred each moment over the internet. Hiding secret messages in an image has been widely used because the images are mostly used in social media applications. The proposed algorithm is a simple algorithm for hiding an image in another image. The proposed technique uses QR factorization to conceal the secret image. The technique successfully hid a gray and color image in another one and the performance of the algorithm was measured by PSNR, SSIM and NCC. The PSNR for the cover image was in the range of 41 to 51 dB. DWT was added to increase the security of the method and this enhanced technique increased the cover PSNR to 48 t0 56 dB. The SSIM is 100% and the NCC is 1 for both implementations. Which improves that the imperceptibility of the algorithm is very high. The comparative analysis showed that the performance of the algorithm is better than other state-of-the-art algorithms

The Hill

The development of technology at this time allows everyone to exchange information without any limitation of time and distance. The possibility that data leakage will occur during the process of exchanging information is carried out, therefore in sending data especially images, security aspects, confidentiality and efficiency of data storage is very necessary. If the important information falls into the wrong hands, it will cause unwanted things, for example manipulation of images with negative shapes and can harm the owner of the image. One method used to maintain data security is cryptography using one of the techniques, Elgamal. The strength of this algorithm lies in the difficulty of calculating discrete algorithms on prime integers in which multiplication operations are performed. In this research, the writer combines Hill Cipher to do image encryption and Elgamal Algorithm to decrypt the key of Hill Cipher. The image is first encrypted using the Hill Cipher, then the Hill Cipher key is encrypted using the Elgamal Algorithm. The implementation of the system uses the programming language Visual Basic Net 2010. The results of the implementation with the initial encrypted image has 4282.85 milliseconds with random images, while the encrypted image will be re-described as having 20442.84 milliseconds with the image returned to the beginning.

Objective: Increases in body weight and declining physical activity that may accompany aging are linked to a range of problems affecting daily life (i.e., decreased mobility and overall quality of life). This study investigates the actual and perceived neighborhood environment on overweight and obese urban older adults. Method: We selected 217 individuals aged 65+ who answered questions about their neighborhood on the 2009 Speak to Your Health survey. Using multinomial regression models and geospatial models, we examined relationships between neighborhood environment and BMI. Results: We found that obese older adults were 63% less likely to have a park within their neighborhood ( p = .04). Our results also show that older adults who perceive their neighborhood crime as very high are 12 times more likely to be overweight ( p = .04). Discussion: Findings suggest that parks may affect BMI in older adults; however, neighborhood perceptions play a greater role.

This article considers the function of friendship as a form of urban relation for young people living in working class areas of Australia’s multicultural capital cities. These neighbourhoods are characterised by very high diversity, significant socioeconomic disadvantage and large youth populations, and over the last five years many have received the largest influx of refugees and migrants of any Australian municipality. Against this backdrop, this article investigates the ways that sociality is produced amongst young people of many backgrounds who must constantly negotiate interethnic propinquity in their daily lives. It explores how young people create ways of being together beyond and beneath the imperatives of formal social cohesion initiatives to participate in harmonious community-making. It argues that everyday forms of convivial co-habitation are produced and regulated through friendship relations and networks that embed mix in daily life, and these can serve to recognise and manage, rather than eliminate, intensity, conflict and ambivalence. It suggests that such practices of sociality complicate mainstream policy endeavours, and can offer some important and hopeful ways to expand theorisation of social relations in the multicultural city.
