Monitoring systems currently applied to concrete bridges include strain gauges, inclinometers, accelerometers and displacement transducers. In general, vertical displacements are one of the parameters that more often need to be assessed because their information reflects the overall response of the bridge span. However, the implementation of systems to continuously and directly observe vertical displacements is known to be difficult. On the other hand, strain gauges and inclinometers are easier to install, but their measurements provide no more than indirect information regarding the bridge deflection. In this context, taking advantage of the information collected through strain gauges and inclinometers, and the processing capabilities of current computers, a procedure to evaluate bridge girder deflections based on polynomial functions is presented. The procedure has been implemented in an existing software system - MENSUSMONITOR -, improving the flexibility in the data handling and enabling faster data processing by means of real time visualization capabilities. Benefiting from these features, a comprehensive analysis aiming at assessing the suitability of polynomial functions as an approximate solution for deflection curves, is presented. The effect of boundary conditions and the influence of the order of the polynomial functions on the accuracy of results are discussed. Some recommendations for further instrumentation plans are provided based on the results of the present analysis. This work is supported throughout by monitoring data collected from a laboratory beam model and two full-scale bridges.

The strategic plan of nutrition education intervention was established to improve nutritional status and reduce nutrition-related diseases for Korean adults. Nutritional problems and risk factors of the nutrition-related diseases were identified to set the long-term goal and objectives for the intervention. The social learning theory and theory of diffusion of innovation served as theoretical basis for this plan. Mass media and interpersonal channels were used to educate the whole adult population and specific target groups. The outline of the educational contents was developed for the whole adult population and slightly modified according to characteristics of the target groups. This plan can serve as a guideline for the operational plans for the future nutrition education intervention.

In order to prevent global warming according to fossil fuel use, countries around the world are making efforts through the Kyoto Protocol and the Paris Climate Change Convention. In addition, in order to prepare for high oil prices, researches such as the development of various renewable energy are being conducted. At present, the domestic production rate of energy sources in Korea is low at 18.1%, and power plants using forest biomass are being constructed to meet the domestic situation where 63% of the land is a forest. In 2015, the global production of wood pellets, a raw material for wood-based biomass power generation, was 28 million tons, up 7.7% from 2014, and has increased tenfold over the last decade. This is a result of increased demand for biomass. Korea is also increasing every year. However, biomass fly ash, an industrial by-product generated by biomass energy generation, is now being disposed of entirely, and there is little research to utilize it. Therefore, this paper will use biomass fly ash, an industrial by-product, which is currently being discarded due to a lack of separate treatment methods, as an admixture concept to contribute to solving environmental problems, developing new admixtures, improving quality, and seeking recycling plans.

Purpose: This study aimed to determine the effect of knowledge and attitudes of preventive behavior plans (PBPs) on Zika virus infection among university students. Methods: Participants included 130 students from H University in Korea. Electronic self-reported questionnaires were used to collect data. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and regression analysis with SPSS/WIN 23.0. Results: The mean percentile score for knowledge was 35.52±20.63. The mean scores for attitudes and PBPs were 3.31±0.47 and 3.07±0.72, respectively, out of 5 points. Knowledge (t=-5.79, p<.001), attitudes (t=-3.17, p=.002), and PBPs (t=-2.67, p=.009) differed significantly with respect to awareness concerning Zika virus infection. The factor 'attitudes' significantly affected PBPs, with an R² value of 12.0% (β=.27, p<.001). Conclusion: Developing a correct attitude toward Zika virus infection may be key to improving preventive behaviors. Health education messages should be tailored to increase preventive behaviors against Zika virus infection. Nursing educators will benefit from partnerships with health educators and by using internet media to speed up the dissemination of Zika virus information.

Upcycling generally refers to the conversion of waste materials to something useful or valuable and is a useful concept that can be applied not only to the waste design industry but also to waste recycling and resource circulation. Our study highlights upcycling as the key concept for improving the value of waste by redefining the concept as "the recycling of waste materials and discarded products in ways that enhance their value." Four upcycling strategies are linked to material flow analyses conducted on waste electronic and electrical equipment, specifically waste refrigerators and waste computers, to examine the technologies available for implementation and suggest guidelines for the promotion of upcycling. The amount of waste refrigerators collected by the formal sector was 121,642 tons/y and the informal sector, 63,823 tons/y. The current recycling ratio of waste refrigerators was estimated as 88.53%. A total of 7,585 tons/y of waste computers were collected by the formal sector and 3,807 tons/y by the informal sector after discharge. Meanwhile, the current recycling ratio of waste computers was estimated as 77.43%. We found that it is possible to introduce 28 upcycling technologies in the case of refrigerators, and 15 technologies are available to promote upcycling in the case of computers. By refining the broad concept of upcycling and looking at the stages of material flow, our approach presents universally applicable directions for incorporating upcycling in resource recovery and recirculation plans.

Dramatic increase of population migrating from suburban area to metropolitan area which started in 1990s resulted in the increase of aging population among this area. Centralized population also causes decreased number of students in suburban areas which in turn affects environmental facilities such as school and brings social issue. Additionally, compared to the alternative analysis and data regarding internal spatial arrangement of high school, there are not enough data or information on external spatial arrangement and how to construct such space. Therefore, the main purpose of this thesis is to provide fundamental data which can be used as a reference in improving educational environment of suburban high school by analyzing and investigating various factors including location, accessibility, facility status, and external spatial arrangement based on arrangement type of 8 normal high schools located across Jeju Island where the trend of decreasing number of students is prominent. Following is the result of such investigation. Despite the fact that high schools from suburban areas in Jeju Island possess diversity based on local characteristic, construction of external space is rather inconsistent as the plans regarding external space is not organized. Therefore, there is a need for preparing external spaces appropriate for each school based on the number of students and the characteristic of gymnasium.

Purpose: This study aimed to understand and describe the diabetes self-management experience of visually impaired people with diabetes. Methods: Ten participants were recruited through a website used by the visually impaired from February to March 2020. Data were collected through two focus group interviews conducted in June 2020; each group consisted of five participants. All interviews were recorded with the consent of the participants and transcribed verbatim. The transcribed data were analyzed using qualitative content analysis. Results: Seven categories were as follows; a two-faced, lifelong companion, an unprepared encounter, struggle to live, love-hate relationship with family, strategies to adapt, lessening attention to self-management, the desire to learn properly. Conclusion: It can be concluded that the visually impaired have fewer opportunities for receiving diabetes self-management education than general diabetic patients. Consequently, plans to improve the education available to such patients are required. Additionally, psychological counseling and diabetes education for patients' families are necessary, and improving the perception of medical workers regarding the visually impaired will be prove useful.
