  • The wireless sensor network (WSN) is well known for an enabling technology for the ubiquitous environment such as real-time surveillance system, habitat monitoring, home automation and healthcare applications. However, the WSN featuring wireless communication through air, a resource constraints device and irregular network topology, is threatened by malicious nodes such as eavesdropping, forgery, illegal modification or denial of services. For this reason, security in the WSN is key factor for utilizing the sensor network into the commercial way. There is a series of symmetric cryptography proposed by laboratory or industry for a long time. Among of them, recently proposed HUMMINGBIRD algorithm, motivated by the design of the well-known Enigma machine, is much more suitable to resource constrained devices, including smart card, sensor node and RFID tags in terms of computational complexity and block size. It also provides resistance to the most common attacks such as linear and differential cryptanalysis. In this paper, we implements ultra-lightweight cryptography, HUMMINGBIRD algorithm into the resource constrained device, sensor node as a perfectly customized design of sensor node.

  • Fisheries resources, due to their intrinsic biological -density dependent, and socio- economic -common property nature, might yield the sustained benefits to the society involved, depending on the degree to which the social management scheme, pursuing the optimum yield from each of them, is framed. And besides, the success or failure of the management on them would, with no doubt, lead parallelly to the direction on scientific study of "Natural Resource Economics." Thus the objectives of the management, to ensue the best use of these society's resource, should underlie the technical, economic, ana social efficiency all together to meet the maximization of society's benefits from yields, taking account of managerial efficiency. And those multiple conflicts need communications between biologists, social scientists, and managers given tile mandate, tobe coordinated to arrive at a unique value weighed, through the well-ordered system approach and resulting timely decision-making which accommodates dynamical fisheries aspects and varying social purposes. purposes.

  • The purpose of this study was to examine the resource transfer process from female baby boomers to their children who have gotten married or plan on getting married. The following research questions were explored. (1)To what extent have female baby boomers been transferring their resources to their children supporting marriage or vice versa? (2)What are the opinions of female baby boomers on future resource transfer plans to their children? (3)What are the opinions of female baby boomers on supporting themselves in their old age, and those of their children on supporting their aging parents? In-depth interviews were conducted with 11 female baby boomers who were born between 1955 to 1963. A case study research method was used to analyze the interview results. The findings were as follows. First, economic resource was the most common type of resources that the interviewees transferred to their children. Those who could not transfer their economic resources instead transferred their instrumental resources. Second, it was anticipated that the current trend of interviewees' resource transfers would be similar in the future. In other words, those who used to transfer a large amount of economic resources to their children showed their willingness to do the same in the future. Third, the interviewees did not expect support from their children, but rather were trying to prepare for their old age by themselves. Based on the overall results, the female baby boomers' transferring economic resources to their children implied that they took responsibility for their children. This appears to stem more from to altruistic motivation than reciprocal motivation. Moreover, it can be cautiously concluded that female baby boomers have different perspectives on the transfer of their resources from male's since the interviewees had different opinions on it from their husbands'.

  • Installed capacity markets in the northeast of the United States ensure that adequate generation exists to satisfy regional loss of load probability (LOLP) criterion. LOLP studies are conducted to determine the amount of capacity that is needed, but they do not consider several factors that substantially affect the calculated distribution of available capacity. These studies do not account for the fact that generation availability increases during periods of high demand and therefore prices, common-cause failures that result in multiple generation units being unavailable at the same time, and the negative correlation between load and available capacity due to temperature and humidity. A categorization of incidents in an existing bulk power reliability database is proposed to analyze the existence and frequency of independent failures and those associated with resource dynamics. Findings are augmented with other empirical findings. Monte Carlo methods are proposed to model these resource dynamics. Using the IEEE Reliability Test System as a single-bus case study, the LOLP results change substantially when these factors are considered. Better data collection is necessary to support the more comprehensive modeling of resource adequacy that is proposed. In addition, a parallel processing method is used to offset the increase in computational times required to model these dynamics.

  • Diarrheal disease is the second leading cause of mortality and morbidity in children under 5 years old worldwide, and is the most common cause of malnutrition in sub-Saharan Africa. In Rwanda, diarrhea is the third leading cause of death in children under 5 years old. This study examined the association between sociodemographic factors and diarrhea in children under 5 years using the data of 7,474 households in the 2014-2015 Rwanda Demographic and Health Survey. Overall prevalence of diarrhea in this study was 12.7% in children. An increased risk for diarrhea was found for children aged 12-23 months (odds ratio (OR)=4.514), those with a low economic status (OR=1.64), those from the Western province (OR=1.439), those with poorly-educated mothers (OR=5.163), and those with families engaged in agricultural activities (OR=1.624). In conclusion, sociodemographic factors significantly affect the risk of developing diarrhea in children under 5 years in Rwanda. Designing and implementing health education promoting awareness of early interventions and rotavirus vaccination are essential to reduce diarrheal diseases for the Rwandan community.

  • Motif which is a recurrent feature shared by a significant segments from the proteins belonging to different families can be used to predict functional or structural properties of the protein, or to describe features common to biologically related proteins. Although there are many existed motif databases, they are unstandardized and built up by different methods. so it is difficult to get enough motif information when researches use motif databases for classification, prediction, etc. Using logical integration of biological based on cross-references between these databases is the common solution for information tracking through www. However, the problem such as the motif resource tracking method for making a united motif information page emerges from cross-reference. In this paper we propose the motif resource tracking method based on the existed motif databases for easy and comfortable interface better than in the case of using each motif database. The result which is given by this method is the review of necessary information about any motif in PROSITE database.
