There has been demands of context-aware systems in a hospital domain and several types of sensors have been applied as sources of medical activities. Unlike the previous passive RFID use of simply identifying objects, this paper presents a system for motion detection of medical objects in a trauma bay by ranging the received signal strength indication (RSSI), using UHF passive RFID tags as one of those sensors that provide information on medical activities. To use passive RFID RSSI for motion detection, Three different types of RSSI estimators are evaluated to process noisy RSSI and the adaptive threshold is proposed in the system to improve the resolution of detecting motion. Our system has been tested with recorded RSSI values in a laboratory and an actual trauma bay during simulated resuscitations performed by trauma teams. The proposed system has achieved 85.9 - 92.1% accuracies for most passive items that are used in a trauma bay.

With the new developments and challenges within the construction industry, improving the construction supply chain is becoming a major concern to both governments and industries. Improving the construction supply chain helps in improving the quality of construction projects, reducing cost, wastes, delays and other disruptions. This paper discusses the analysis of material flow in the construction supply chain. The methodology consisted of preliminary investigations, survey and simulation development to analyse the extent of impact that material flow has on construction projects in Jordan. Both the main survey and the investigations revealed that material flow delays, are caused mainly by 3 types of delays; late delivery, wrong specification and material damaged on site. The highest impact regarding late deliveries was scaffolding with a 16% probability of occurrence, a 2-day delay on the activity’s duration. Concrete ranked highest regarding wrong specification with a 19% probability of occurrence, an 8-day delay the activity’s duration. Regarding materials damaged on site, bricks ranked highest with a 9% probability of occurrence, a 3-day delay on the duration. The simulation results exhibited a delay of 50% on the projects duration and a probability of a delay occurring is 9.2%.

In nowadays Europe, a wind of terror, of an intensity comparable to that of the belligerent periods, walks freely and occasionally strikes the apparent tranquility of our lives. Islamic fundamentalist attacks, seemingly coming from nowhere, without prior psychological preparation manage to create hardly measurable effects. Media and, consequently, public opinion resonate dramatically to a reality that is destabilizing the social, political, economic, cultural, individual or group balance in many parts of this bewildered and concerned Europe. It is a tense context, in which fear and terror annihilate rationality and freedom of expression being able to maintain a toxic atmosphere of information, and independent media can serve conjecturally, unintentionally even to the harmful interests of those terrorist groups.

Gaultherin is the active form of salicylate from plants Gandapura. Gaultherin has some characterictics which make it potential to become a natural aspirin, anti-cancer, antiinflamatory dan cardiopulmonary. Currently, aspirin (acetylsalicylic acid) is a medicine which is used by most of the people in this world because of its function as antipiretic, antiinflamatory, and analgesic. Approximately the need of pharmacy industry towards gaultherin will be increased in the following year. However, at the time being, there is still no any effective methods to produce gaultherin from gandapura. This difficulty in the process of taking gaultherin is based on the process of its extraction, where the tissue is broken, so, gaultherin will be hydrolyzed change to be its individual components, like methyl salicylate and disaccharides. The hydrolysis process is believed to be catalyzed by the enzyme gaultherase inside. This research is aimed to analyze the production of gaultherin form gandapura using the gaultherase enzyme inactivation process through extraction with alcoholic solvent and determine the correct condition to get the highest production of gaultherin. The result of the calculation shows that the bioextraction process variables of gaultherase enzyme inactivation which is mostly influential are pH and alcohol concentration. The more pH extraction, will increase the outcome of gaultherin active compounds The optimum condition of bioextraction enzyme inactivation is in pH 8 with 14,46% gaultherin active compounds and regression equation in . The bigger solvent concentration, the more gaultherin be extracted. The production of gaultherin will optimally reached in the 90% concentration of ethanol with the result of 13,10% active compounds

This research work investigated the firewall security and performance relationship for distributed systems. Internet connectivity is growing with most enterprises migrating to the use of web based services for services provision. As organization grab the Internet as another business tool whether to sell, to team up or to communicate - web applications have turned into the new weakest connection in the organization's security technique. Firewalls provide a mechanism for protecting these enterprises from the less secure internet over which customers or collaborating partners transfer packets destined for the corporate network. The connection between the security and execution proficiency is exhibited through distinctive scenarios and the relationship between security and performance in firewalls is assessed. We demonstrated distinctive networks (with and without firewalls and diverse firewall functionality and simulated such systems with an eye on their performance). The simulation was done for 300 work stations and simulated in a way that all the 300 work stations access an email and web application under three different scenarios. Attention is on the relationship between system security and performance; the impacts of firewalls on system execution. Different scenarios were assessed through simulations utilizing OPNET IT Guru Academic Edition 9.1 to demonstrate the impacts of firewalls on system performance. The result shows that maintaining security which involves the utilization of numerous applications and the use of firewall has an effect on network performance.

A study conducted in an Small and Medium scale Enterprise (SME) revealed that a Vertical Milling Centre (VMC) frequently faces circularity deviations while machining the Arm of a Self Centering Steady Rest. A cause and effect analysis is carried out to determine the probable causes of deviations. Further more a statistical analysis of the deviations using ANOVA revealed that the circularity deviations are related to the linear worktable movement of the VMC. In order to overcome the deviations VMC was recalibrated. After recalibration of VMC, an analysis on new sample revealed that there was no circularity deviations observed beyond the specified tolerance limits.

This study deals with biodegradation experiment on soil contaminated with crude oil. The soil sample sets A, B,C D, E, F, G were amended with inorganic fertilizer to enhance microbial growth and hydrocarbon degradation, moisture content of some of the sets were as well varied. Biodegradation ratios (nC17/Pr, nC18/Ph and (nC17+nC18)/(Pr+Ph) were used to monitor biodegradation of soil sets A, B,C D, E, F, G for a period of 180. The soil samples were each contaminated with the same amount of crude oil and exposed to specific substrate treatment regarding the amount of nutrients and water content over the same period of time. The trend in biodegradation of the different soil sample sets shows that biodegradation ratio (nC17+nC18)/(Pr+Ph) was more reflective of and explains the biodegradation trend in all the sample sets throughout the period of the experiment, hence, a better parameter ratio for monitoring trend of biostimulated biodegradation. The order of preference of the biodegradation ratios is expressed as nC18/Ph < nC17/Pr < (nC17+nC18)/ (Pr+Ph). This can be a relevant support tool when designing bioremediation plan on field.

Due to the technological advancement, enormous micro data containing detailed individual information is being collected by both public and private organizations. The demand for releasing this data to public for social and economic welfare is growing. Also the organizations holding the data are under pressure to publish the data for proving their transparency. Since this micro data contains sensitive information about individuals, the raw data needs to be sanitized to preserve privacy of the individuals before releasing it to the public. There are different types of data sanitization methods and many techniques are being proposed for Privacy Preserving Data Publishing (PPDP) of micro data. Synthetic Data Generation is an alternative to data masking techniques for preserving privacy. In this paper different fully and partially synthetic data generation techniques are reviewed and key research gaps are identified which needs to be focused in the future research.

Indonesia's economic fundamentals have not prompted the government to build the economic structures to the existence of Micro. Small and Medium Enterprises (SMEs). This sector has been proven to provide jobs and provide opportunities for SMEs to thrive in the community. MSMEs can’t be doubted because it proved able to survive and become the economic driving, especially after the economic crisis. On the other hand SMEs are also facing many problems, the limited working capital, human resources is low, and less clever mastery of science and technology. Another obstacle faced by SMEs is the relationship with the business outlook is less clear and the vision and mission planning is not yet stable. Provision of information and networking markets, ease of access to funding and mentoring and capacity building in information technology are some strategies for improving the competitiveness of SMEs in Indonesia. Therefore, it is necessary synergy between all parties, especially the government and microfinance institutions. This model is based on the consideration of SMEs as the largest group of economic actors in the Indonesian economy. The method used in this study is a survey explanatory, with the technique of data collection through questionnaires, interviews and observation. The population of the Small and Medium Industries (SMI) Shoes Cibaduyut Bandung. Then analyzed with descriptive scoring system and non-parametric statistics through different test average.

The suitability of local quartz sand in the production of bath crucibles is a study that was carried out in order to impart overall strength on bath crucibles, hence reduce breakages during fettling. Therefore, this research constitutes a study to enhance the efficiency of production of bath crucibles by addition of quartz sand in slip preparation. The steps taken in the beneficiation of quartz sand for the production of bath crucibles are comminution which entails crushing and milling, classification, washing, liquid dispersion, sizing and reduction of iron content by magnetic separation. The slip contains materials like plastic clay, feldspar, kaolin, talc, sodium silicate, water, quartz sand, etc. These were all milled in the ball mill for slip production, casting and fettling, glazing and sintering to get final bath crucibles as the end products. Quartz sand is used in a variety of products essentially as raw material for the foundry casting and glass industries and also in chemicals, water filtration and ceramics, the heat resistance nature of quartz sand makes it an excellent refractory substance for these industrial processes. Slip can be prepared for production of bath crucibles without the inclusion of quartz sand; however the addition of quartz sand is needed to improve the mechanical performance of the slip in the production of bath crucibles.

This study focuses on the small-scale artisanal fishery that captures blue marlins (Makaira nigricans) in Cote d'Ivoire. The sizes, weights and quantities landed of this species were approached according to the marine seasons and fishing areas. These fishermen, mostly Ghanaians, use canoes (12 to 17 m) as craft, and drifting gillnets (4800 to 5400 m) to catch fish. The choice of fishing area depends on the direction of the current. When the current flows westward, fishing takes place in the east, and vice versa. These choices have the advantage that, at the return, the driving force is developed in the direction of the current. In either case, the net is arranged perpendicularly to the direction of the current to act as a filtering barrier. In the absence of marine current, the net is arranged perpendicularly to the north-south axis. The Man-Whitney test applied to maturity states following seasons and fishing areas showed a significant difference (P <0.05). Sector A2 (offshore waters in front of Abidjan, Grand Bassam and Jacqueville) would be conducive to the capture of mature individuals during warm seas. On the other hand, during upwelling, fishing should be favorable to sector B (offshore waters in front of Grand-Lahou and Fresco) where adult marlins are accessible. Capturing M. nigricans on the continental shelf should be discouraged, as recruits abound in this area to feed and shelter from large offshore predators.
