Author(s): Aung Kyaw Oo, Aye Zarchi Minn
Data mining is a procedure of extraction of information and knowledge that are hided in data, unknown by people and potentially useful from a large quantity of data with multiple characteristics. The data-mining model based on genetic neural network has been widely applied to the procedure of data mining. This paper presents a method that combines the learning algorithm of Back Propagation (BP) neural network with genetic algorithm to train BP network and optimize the weight values of the network. The system uses a single hidden layer. Input for the system is training data set of police office data. Each attribute values are all numeric-valued. At the beginning, each training data set is trained using Neural Network architecture with sigmoid function. Then, by using GA, neural network weights are chosen as parents for selection, crossover and mutation. The weights are optimized, using genetic algorithm. The fitness is calculated and the selection is performed with method of roulette wheel selection. This system can be solved cases of police office rapidly and make decisions efficiently using the historical data.

Author(s): Haytham Jaradat, Abdullah Sani Kamaluddin, Marzuki Ibrahim
Globally, daylight is an important issue in the modern architecture. Since, it affects the functional arrangement of spaces, occupant comfort, structure, and energy use in the buildings. Locally, in Jordan,there is a lack of studies that deal with architectural and interior design efforts to address the indoor daylight quality in houses. Also, Atrium houses are not widely spread in Jordan. The study aimed to; measure the satisfaction levels of atrium roof residents with daylight at Jordan in terms of interior design suitability, thermal comfort, and interior visual comfort. Methodologies: The research methodologies are quantitative and cross-sectional ones. The study conducted in Amman, Jordan. A sample of (355) respondents filled the self-administration questionnaire properly. The questionnaire had been developed based on previous studies, and its validity and reliability were done. Results: The study concluded that, Jordanians were satisfied regarding the daylight in their atrium roofs in terms of interior design suitability,thermal comfort, and interior visual comfort. The research findings suggest that Atrium Day Lighting in Jordanian residential building is crucial to be analysed and it is also significantly dependent on the identified factors; the interior design, thermal comfort as well as the vision comfort. All of these factors help the related residential sites constructors to have an insight about the factors that need to be focused upon while designing.

Using Adsorption Method by Tea Leaves to Minimize Sulfate Ion Concentration in Polluted Water
Author(s): Hyman Jafar Meerza Al-Jaaf
The research aims to study minimizing ordecreasing sulfate ion concentration inpolluted water using adsorption method bytealeaves. The samples were collected from four areas on the Tigris River side in Baghdad city that are, Bab Al-Muddam, Al-Doora, Al-Kademiyah and Al-Adamiyah. At these areas and on the river sides, there are hospitals, Electric power plants, factories, restaurants and residential houses. The result showed that before adsorption method at standard temperature, sulfate ion concentration was high. This referred that these institutes might be pour theirswastewater directly to the river, which leads to pollute the water of the river. Therefore, the wastewaterneeded to be treated before pouring to the river.After adsorption, sulfate ion concentration is decreased gradually depending on twofactors, which are temperature and contact time.The results presented that adsorption process by using tealeaves as an adsorption material hadsignificant impact in decreasing sulfate ion concentration in polluted water. On the other hand, the temperature as a factor was more effective than contact time in minimizing sulfate ion concentration inpolluted water until reach the desired value (200-400mg/l) as standard Iraqi’s requirements..

Silenced Violence Versus Instagram Likes: Are They The Same?
Author(s): Arlo Parker
It is not often that a simple caption change under a photo on Instagram leads to death threats. And yet, it is exactly what happened when an Instagrammer Essena O’Neill changed the captions on her photos. O’Neill, 18, is an Australian Instagram model, who leveraged a “contrived” sense of beauty and her great genes, to create an image of a perfect carefree coquettish blonde with an illuminating smile, graceful posture, tiny waist, – seemingly enjoying life – all while making profits from the advertisement endorsements. It is interesting that whenO’Neill changed alluring captions on her photos to more accurate descriptions of what was actually happening at the time the photo was taken, her followers had an extremely negative reaction to the point of sending her death threats. One week later, she deleted most of her photos,accounts, and decided to quit social media altogether..

Effect of Crosslinker Addition on the Composite Characteristics of Bacterial Cellulose-Aloe vera Extract
Author(s): Nanda Cimpia, Ananda Putra
Bacterial cellulose can be applied in various fields such as the biomedical field, separation membranes, artificial blood vessels, and substrates for tissue engineered cartilage. Bacterial cellulose still has low mechanical properties, so that a composite of bacterial cellulose with aloe vera extract (BC-AvE) is formed to get a new better material. The purpose of this study was to determine the effect of crosslinkers (wheat flour, tapioca flour, and glutinous rice flour) on the mechanical, physical, and structural properties of BC-AvE composites. Bacterial cellulose is produced from a mixture of coconut water, sugar and urea. Then it ferments with acetobacter xylinum for 14 days. The bacterial cellulose formed in the composite with an aloe vera extract and its called bacterial cellulose-aloe vera extract (BC-AvE). BC-AvE composites will be characterized by testing tensile strenght, water content, and structural analysis with FTIR. Addition of crosslinkers can reduce the percentage of water content of BC-AvE. The best tensile strength test results were BC-AvE which added tapioca flour solution with a value of 68,13 MPa. Futhermore, the FTIR spectrum shows that the clusters of functions in cellulose are just shifting.
