In the area of aircraft maintenance, we commonly meet with the problem of corrosion, detection of which is one of the primary obstacles. Implementation of modern sensing techniques has a potential to bring many benefits. The objective of this work is to analyze technologies, their potential applications, and viability of switching to autonomous detection using computer aided sensing. Primary source of information were research articles from science databases such as ResearchGate and ScienceDirect. Available documents were analyzed and subsequently, useful information was extracted. First part deals with theretical knowledge about corrosion, based on which potential technologies were chosen. Those were then described, and their viability was analyzed, based on how well they could achieve our goals. Selected technologies have shown potential, however necessary solutions could not be found to enable fully switching tou autonomous computer detection. Although data acquired show many potential benefits that could arise from partial implementation of these technologies combined fith old fashioned visual inspection.

Abstract Objective: To clarify nutrient supplementation usage and primary source of information among pregnant women in China. Design: This cross-sectional study used information on nutrient supplementation and primary source of information collected via face-to-face interviews. Data on the usage of folic acid, calcium/vitamin D, iron, vitamins, docosahexaenoic acid, and other dietary supplements were collected. Primary source of information were categorized as family/relatives, friends/co-workers, the Internet, books/magazines, television/radio, doctors, other people, and oneself. Setting: Maternal and Child Health Hospital in Chengdu, China. Participants: 1081 Chinese pregnant women aged ≥ 20 years with singleton pregnancies. Results: In all three trimesters of pregnancy, usage was highest and most stable for folic acid (81.7%), followed by vitamins (vitamin A, B-group vitamins, vitamin C, and multivitamins; 75.0%), whereas calcium/vitamin D (51.4%) and iron (18.1%) usage was low, potentially indicating a deficiency risk. All supplementation usage percentages increased with pregnancy duration (p < 0.05). Notably, approximately 10% of the pregnant women in our study did not use any nutrient supplementation, and this was especially common in early pregnancy. More than 50% of the women reported getting information on nutrient supplementation from family members, and about 30% reported getting this information from doctors. Conclusions: Among pregnant women in China, awareness about nutrient supplementation increases as the pregnancy progresses, but some types of nutrient supplementation (such as calcium/vitamin D and iron) remain at low levels. It is necessary to pay more attention to the health education of pregnant women in China, and the influence of family members should be emphasized.

Previous work has shown that wallboard can be successfully manufactured to contain up to 30 percent phase-change material (PCM), or wax, thus enabling this common building material to serve as a thermal energy storage device. The PCM wallboard was analyzed for passive solar applications and found to save energy with a reasonable payback time period of five years. Further evaluations of the wallboard are reported in this paper. This analysis looks at potential applications of PCM wallboard as a load management device and as a comfort enhancer. Results show that the wallboard is ineffective in modifying the comfort level but can provide significant load management relief. In some applications the load management strategy also serves to save a small amount of energy, in others there is a small energy penalty.

Beloved Disciple

Discussions of the authorship of the Gospel of John must answer two questions: who is the Beloved Disciple who is portrayed as the book’s primary source of information, and how is this individual related to the author, John the evangelist? On the first question, scholars are divided on whether the Beloved Disciple is a real historical individual or an ideal symbolic figure. Data from the text itself and from social-science perspectives on the reputations of key figures from the past suggest that both are correct: the Beloved Disciple was a legendary associate of Jesus whose presentation reflects his reputation as a source of information that was critical to the Johannine theological outlook. On the second question, data suggests that the evangelist was not the Beloved Disciple but rather a disciple of that individual, perhaps basing his own book on an earlier document produced by the Beloved Disciple.

Special Case

Recent experiences with interpretation of orthonormal coordinates in compositionaldata show clearly a necessity of their better understanding in terms of logratios that formthe primary source of information within the logratio methodology. This is even morecrucial in the special case of compositional tables, where both balances and coordinateswith odds ratio interpretation are involved. The aim of the paper is to provide a decompo-sition of covariance structure of orthonormal coordinates in compositional tables in termsof logratio variances that could serve for this purpose. For their better interpretability,the formulas are also accompanied with appropriate comments and graphical illustrations,and implications for the prominent case of 2 2 compositional tables are discussed.

Purpose The purpose of this paper is to understand the behavior diversities that exist among young millennials’ subgroups in ways they seek health-related information. Design/methodology/approach The authors ran several sets of analyses on the 2012–2014 US Program for the International Assessment of Adult Competencies (PIAAC) Data using Stata. The population was stratified into four specific subgroups based on their gender, ethnicity—blacks, Hispanics and whites—immigration status, college status—whether they were enrolled in a program of study at the time of the survey. The outcome variables were sources of health information including print (books/magazines/brochures), traditional media (Radio/TV), internet, family/friends/co-workers and health professionals. The independent variables were gender, ethnicity, educational status and immigration status. The authors utilized the appropriate sample weight derived by Organization for Economic Cooperation and Development so the findings can be generalized to the populations. The analysis included several descriptive statistics and χ2 test of independence. Findings Despite similarities, young adults’ health seeking behavior is complex influenced by gender, ethnicity, immigration status and education. The results indicated that while the internet is the primary source of health-related information for all young adults, there are subtle differences in utilizing other available resources. For example while more educated young adults seek help from their family members, the less educated peers use the media to obtain health-related information. Ethnicity has also an effect on young adults’ information seeking behavior. The number of Hispanics and blacks that obtain their information from traditional media is significantly higher than their white counterparts. Research limitations/implications This study has several limitations. First, the authors did not consider the effect of young adults’ digital literacy skills, problem solving skills and numeracy skills on their health seeking approach. Including these cognitive skills could reveal key information about young adults approach to information seeking that is not apparent by race, ethnicity and gender only. Another limitation of this study is the lack of the ability to claim causation, PIAAC data are designed strictly for cross-sectional analysis. Practical implications Although, behaviors often do not change simply by presenting information, trying to change behavior without improving individuals’ understanding of the issue by providing accurate information is likely to fail. Providing standardized health-related information sources that are accessible to all is vitally important. The results indicate that while the majority of young adults use the internet as their primary source of information only a few percentage of young adults seek information from health professional. Consequently, there is a need for an easily accessible and standardized online health-related source of information. Social implications Healthcare facilities and health related industries have the resources and the ability to develop a reliable infrastructure that could potentially provide reliable information that is easy to understand and navigate for adults with a variety of literacy and skills to use. Perhaps adopting the Universal Design for Learning approach and providing information that is accessible to a variety of individuals regardless of their education, learning skills and language skills. Flexible learning resources provided within a standard infrastructure accessible to all can help individuals find trustworthy and consistent information that they can trust. Originality/value Despite the unique characteristics of the millennials and the profound change in the way young adults seek information, there is a paucity of research on the ways young adults seek health-related information. Most existing literature is based on locally developed surveys and convenient sampling with limited reliability and validity information. Consequently making a sweeping statement based on their findings is considered as hasty generalization. The PIAAC, on the other hand, is a nationally representative data, extensively examined for its validity and reliability.

This chapter discusses six trends in congregational life: looser connections between congregations and denominations, more computer technology, more informal worship, older congregants, more high-income and college-educated congregants, and, what is perhaps most important, more people concentrated in very large churches. Taken together, these trends show that congregations are shaped by the same cultural, social, and economic pressures affecting American life and institutions more generally. The National Congregations Study (NCS), which began in 1998, is the primary source of information for several of the trends described in this chapter. As with change in American religion as a whole, trends in congregational life should be seen against the backdrop of substantial continuity, especially for the relatively brief period covered by the NCS.

The purpose of this study is to examine whether Multimedia learning theory (Mayer, 1997; Schnotz & Kürschner, 2007) holds true when images are the primary source of information and text information is secondary. I will test how temporal arrangement of audio and image presentations affects quality of learning in this situation. I hypothesize that when audio is played before or after the image participants will require increased cognitive processing to mentally integrate the two sources of information resulting in deeper learning and transfer of learning. On the other hand when audio is played while the image is shown, I hypothesize that participants with high prior knowledge of the subject will score lower than participants with low prior knowledge, because prior knowledge will interfere with knowledge from the two sources causing a redundancy effect. This experiment will lead to greater understanding of multimedia teaching and learning in classrooms as well as how it affects deeper learning.

Traditional government structures are sometimes regarded as overly bulky. However, with the rapid expansion of interconnected computer networks and the progressive development of information technology (IT), it is now possible to exchange massive amounts of data at light speed over great distances. These infrastructures and technologies provide the opportunity for governments to transform themselves from huge monsters to compact and efficient organizations. Realizing the potential benefits of IT, as of summer 2004, 198 governments had started their e-government plans to construct digital government based on the Internet (West, 2004). One of the essential features of e-government is the transmission of confidential information via computer networks. Depending on the sensitivity of the information, the security of some information should be treated at the same level as national security. Although each e-government has its own networks, no government can say no to the Internet, because it would be a waste of resource. However, the Internet is an open environment; therefore, protecting data flowing on the Internet from attacks is a pressing e-government issue. All governments with such strategies have sought help from cryptographers and devoted huge amounts of both money and time to the development of specially designed information systems and advanced cryptosystems to strengthen information security. Unfortunately, cryptography is not adequate in some applications. As computing power keeps increasing and the techniques of cryptanalysis keep advancing, contemporary cryptosystems cannot and will not work forever. At the 24th Annual International Cryptology Conference (CRYPTO’04), MD5 and a series of related cryptosystems, which are currently in widespread use, were proved unreliable (Wang, Feng, Lai, & Yu, 2004). From the last decade, steganology—the technique for digitally hiding and detecting information – is attracting more attention. It is already regarded as a powerful complement to cryptology and a promising technique for ensuring e-national security. Unlike cryptology, which renders the encrypted information completely meaningless, steganology keeps the host media perceptually unchanged after hiding the secret information. This article will provide an in-depth explanation of the two components of steganology, namely steganography and steganalysis, and discuss their potential applications in the realm of e-national security.
