The United States (US) National Science Foundation's (NSF's) National Ecological Observatory Network (NEON) is a continental-scale observation facility, constructed and operated by Battelle, that collects long-term ecological data to better understand and forecast how US ecosystems are changing. All data and samples are collected using standardized methods at 81 field sites across the US and are freely and openly available through the NEON data portal, application programming interface (API), and the NEON Biorepository. NSF led a decade-long design process with the research community, including numerous workshops to inform the key features of NEON, culminating in a formal final design review with an expert panel in 2009. The NEON construction phase began in 2012 and was completed in May 2019, when the observatory began the full operations phase. Full operations are defined as all 81 NEON sites completely built and fully operational, with data being collected using instrumented and observational methods. The intent of the NSF is for NEON operations to continue over a 30-year period. Each challenge encountered, problem solved, and risk realized on NEON offers up lessons learned for constructing and operating distributed ecological data collection infrastructure and data networks. NEON's construction phase included offices, labs, towers, aquatic instrumentation, terrestrial sampling plots, permits, development and testing of the instrumentation and associated cyberinfrastructure, and the development of community-supported collection plans. Although colocation of some sites with existing research sites and use of mostly "off the shelf" instrumentation was part of the design, successful completion of the construction phase required the development of new technologies and software for collecting and processing the hundreds of samples and 5.6 billion data records a day produced across NEON. Continued operation of NEON involves reexamining the decisions made in the past and using the input of the scientific community to evolve, upgrade, and improve data collection and resiliency at the field sites. Successes to date include improvements in flexibility and resilience for aquatic infrastructure designs, improved engagement with the scientific community that uses NEON data, and enhanced methods to deal with obsolescence of the instrumentation and infrastructure across the observatory.

The purpose of this study was to examine the relationship between sleep disorders, job satisfaction, health promotion behavior, quality of life, turnover intention. And also to find the predicting factors on turnover intention of shift and non-shift nurses. A descriptive study design was used. Study subjects were 239 nurses worked as a shift (167) and non-shift (72) in two general hospitals in P city. Turnover Intent, Sleep disorders, Job satisfaction, practicing health promotion profile and quality of life scales were used to collect the data. Data were analyzed by descriptive statistics and Pearson's correlation coefficient for find the relationship between study variables. Stepwise multiple regressions used to find predicting factors of turnover intention with other variables. The shift group showed lower Job satisfaction, practice of health promotion behavior and intention of turnover than non-shift nurses. The most important predictive factors of turnover intention in of shift group was job satisfaction (β =-. 477, p <.001) and non-shift group was health promotion behavior (β =-. 295, p = .040) than other factors. Findings showed that turnover intention highly influenced by job satisfaction than health promoting behavior and quality of life. This study suggests organizational efforts to provide sufficient staffing and nurse managersshould make more concentration to allot work schedule in order to avoid over load shift nurses and promote quality of client care.

Although a number of container terminal simulators have been developed for various purposes, none of the existing simulators allow the system structure to reuse the system structure depending on application. Our goal is to develop highly reusable, highly inter-operable and flexible container terminal simulation system. The High Level Architecture(HLA) is an architecture for reuse and inter-operation of simulation. It is based on premise that no simulation can satisfy all use and users. An individual simulation or set of simulations developed for one purpose can be applied to another application under the HLA concept of the federation : a composable set of interacting simulations. The intent of the HLA is a structure which will support reuse of capabilities available in different simulations, ultimately reducing the cost and time required to create a synthetic environment for a new purpose, and the possibility of distributed collaborative development of complex simulation applications. In this paper, we discuss the design of a HLA-based port container terminal simulation system. Furthermore, we describe various technical motivations for HLA, the key elements of the architecture and how they are minimum and essential to the goal of reuse and interoperability.

The use of lightweight aggregate (LWA) instead of ordinary aggregate may make lightweight aggregate concrete, which possesses many advantages such as lightweight, lower thermal conductivity, and better fire and seismic resistance. Recently the developments of LWA have been focused on using industrial wastes as raw materials to reduce the use of limited natural resources. In view of this, the intent of this study was to apply Taguchi optimization technique in determining process condition for producing synthetic LWA by incorporating waste thin film transition liquid crystal displays (TFT-LCD) glass powder with reservoir sediments. In the study the waste TFT-LCD glass cullet was used as an additive. It was incorporated with reservoir sediments to produce LWA. Taguchi method with an orthogonal array L16(45) and five controllable 4-level factors (i.e., cullet content, preheat temperature, preheat time, sintering temperature, and sintering time) was adopted. Then, in order to optimize the selected parameters, the analysis of variance method was used to explore the effects of the experimental factors on the performances (particle density, water absorption, bloating ratio, and loss of ignition) of the produced LWA. The results showed that it is possible to produce high performance LWA by incorporating waste TFT-LCD glass cullet with reservoir sediments. Moreover, Taguchi method is a promising approach for optimizing process condition of synthetic LWA using recycled glass cullet and reservoir sediments and it significantly reduces the number of tests.

Purpose - This paper want to confirm whether the guilty consciousness moderates the relationship between luxury brand awareness and purchase intention. The purpose of this study is to clarify the effect of buying intention of counterfeit luxury brand and to increase intention of purchase of genuine brand. Research design, data, and methodology - This study was analyzed using SPSS 19 and SPSS Macro. An internal consistency analysis was performed to verify the reliability of the measuring instruments and Pearson's miniscule correlation to examine the correlation of variants. In addition, the data were averaged to perform regression analysis and to see the control effects of guilt, and the significance of the control effect was verified using SPSS Macro. Results - The first hypothesis that the perception of luxury brands will have a positive effect on the intent of buying counterfeit luxury brands was found to be significant. Next, a hypothesis was also established that the sense of guilt would have a significant moderating effect on the relationship between the recognition of a luxury brand and the intention of buying a counterfeit brand. Conclusions - The study expanded the study of counterfeit brand names by making an empirical check on the effects of brand awareness and guilt for the first time in the research done so far.

Research design, data and methodology: This study performed a survey that targeted people who have purchased travel products using Online Travel Agencies in the past year at Incheon International Airport. Out of 280 questionnaires, this study selected 249(88.9%) questionnaires for analysis. In analysis, this study used statistical package called 'SPSS 22'. Results: Based on the results, this study identified that company reputation and transactional stability influenced consumers' intent to share anecdotal and practical information. Conclusions: This study discovered several major findings. First, 'convenience' and 'price', two major factors in service quality, imposed positive effects on word-of-mouth intention of consumers. In particular, 'convenience' had the most significant impact. Next, this study verified the moderating effects of 'transaction safety' and 'reputation' on the effect relationships between 'convenience' and 'price', and consumer word-of-mouth intention. The results conclude that, in fact, some statistically significant differences among the effect degrees of the two independent variables on the dependent variable according to the safety level of transaction on Online Travel Agencies website do exist. In short, 'transaction safety' variable does have moderating effects on the above relationships.

This numerical analysis uses the lifting surface method and frequency-domain panel method based on the linear compressible aerodynamic theory. Increased knowledge of flow conditions within mixed-flow fan should indicates means of improving performance of these turbomachines. Thus, only an approximate solution is obtained whose prime intent is to recognize the most significant characteristics of the "ideal" geometry. For a given set of operating condition, the flow conditions within mixed-flow fan depend on the geometry of the machine (three-dimensional flow effects) and on the properties of the fluid. But most treatments of the problem have been concerned with the two-dimensional flow effects for incompressible, non-viscous fluids. Interest in the field of mixed-flow fan resulted in the undertaking of a program to develop reliable design procedures that would avoid the need for lengthy development work.

In the recent trend where crime types are being diversified along with urban expansion, we are facing the reality of a 'taking-it-out-on-somebody' crime, which targets the public rather than a specific person with criminal intent, like a 'random target crime.' A park, which is a public space for urban dwellers' and residents' leisure and rest in the midst of social changes, can be called the spot where various crimes occur. This is because it is a space without boundaries, available for the influx of many and unspecified persons, thus making it difficult to specify users. For the purpose of keeping a park safe from crime and providing users with psychological stability, this study carried out its research to get basic knowledge of the introduction of CPTED (Crime Prevention Through Environmental Design) concept in park development. The park development guideline contents are analyzed based on the six principles of CPTED theory as per the space composition element of a park. As a result, this study found out a problem was that most guidelines applied to the space composition element of a park were fragmentary in applying the six principles of CPTED theory, and were focused on arrangement and installation of facilities.
