In this study a new design concept of the Fabry-Perot filter, constructed with an anisotropic space layer and a couple of isotropic mirrors, was proposed based on the Maxwell equations and the characteristic matrix method. The single- and double-cavity Fabry-Perot filters were designed, and their optical properties were investigated with a developed software package. In addition, the dependence of the transmittance and phase shift for two orthogonal polarization states on the column angle of the anisotropic space layer and the incidence angle were discussed. We demonstrated that the polarization state of electromagnetic waves and phase shifts can be modulated by exploiting an anisotropic space layer in a polarization F-P filter. Birefringence of the anisotropic space layer provided a sophisticated phase modulation with varied incidence angles over a broad range, resulting in a wide-angle phase shift. This new concept would be useful for designing optical components with isotropic and anisotropic materials.

Purpose: This study aimed to examine the influence of family support and death preparation on the quality of life in home care hospice patients. Methods: The study recruited 117 patients in home care hospice in four general tertiary hospitals and three general hospitals in three cities. Data were collected using self-reported questionnaires from September 1, 2019 to March 31, 2020 and analyzed using the statistical package IBM SPSS software version 22.0. Results: The quality of life according to the participants' general characteristics of the subjects shows a statistically significant difference between patients who live with supporters and those who do not(Z=2.96, p=.003). A statistically significant correlation was found between predictors such as family support, death preparation, and quality of life. Family support and death preparation affect the quality of life in home care hospice patients and these variables could explain 33.7% of it. Conclusion: To improve the quality of life in home care hospice patients, we should develop an intervention to enhance family support and death preparation.

The main objective of the study is to find out the level of information-seeking behaviour of auto mechanics working at Siwdu and its impact on the work they do. Two methods of data collection instruments were used; these included a questionnaire and interview schedule. The researchers personally administered fifty-three questionnaires of which forty-eight completed ones were received. Twelve (12) people were interviewed at their respective workshops. The respondents were registered members of Siwdu Auto Mechanic Association and the total number of sixty respondents used represented 20% of total number of members. Quantitative data obtained mainly from the questionnaire were analysed using Statistical Package for Social Sciences (SPSS) software version 20. Responses for the interview were analysed thematically. Some of the major findings are as follows: The majority of the respondents did not know how to get information from the library; some of the respondents preferred consulting their "Masters" for help; majority of the respondents had Android phones but did not know how to access relevant information; respondents were aware of the benefits of authentic information; and respondents recommended that Management of libraries should organise seminars and workshops for auto mechanics to enable them know how and where to access information. Information is needed by everybody to enhance efficiency therefore creating the awareness of the sources of information is a way of increasing productivity. Knowing the level of information-seeking behaviour of people in every manner of job is essential in the nation's human resource development.

To provide a simplified method for the base isolation design of LNG tanks, such as $16{\times}104m^3$ LNG tanks, we conducted a derivation and calculation example analysis of the dynamic response of the base isolation of LNG storage tanks, using dynamic response analysis theory with consideration of pile-soil interaction. The ADINA finite element software package was used to conduct the numerical simulation analysis, and compare it with the theoretical solution. The ground-shaking table experiment of LNG tank base isolation was carried out simultaneously. The results show that the pile-soil interaction is not obvious under the condition of base isolation. Comparing base isolation to no isolation, the seismic response clearly decreases, but there is less of an effect on the shaking wave height after adopting pile top isolation support. This indicates that the basic isolation measures cannot control the wave height. A comparison of the shaking table experiment with the finite element solution and the theoretical solution shows that the finite element solution and theoretical solution are feasible. The three experiments are mutually verified.

This study reports on the dissolution behavior of SrO in LiCl at varying SrO concentrations from low concentrations to excess. The amount of SrO dissolved in the molten salt and the species present upon cooling were determined. The thermal behavior of LiCl containing various concentrations of SrO was investigated. The experimental results were compared with results from the simulated results using the HSC Chemistry software package. Although the reaction of SrO with LiCl in the standard state at 650 ℃ has a slightly positive Gibbs free energy, SrO was found to be highly soluble in LiCl. Experimentally determined SrO concentrations were found to be considerably higher than those present in used nuclear fuel (<2 g/kg). As Sr-90 is one of the most important heat-generating nuclides in used nuclear fuel, this finding will be impactful in the development of fast, simple, and proliferation-resistant heat reduction processes for used nuclear fuel without the need for separating nuclear materials. Heat reduction is important as it decreases both the volume necessary for final disposal and the worker handling risk.

This study is to analyze the structure of the networks of tourism marketing on Twitter, identifying the most prominent users, the flow of information about tourism marketing, and the interaction between the users posting tweets. This study employs NodeXL pro as a visualization software package for social network analysis. The number of vertices or nodes is 171, and the number of the unique edges or links is 128, but there are 101 edges with duplicates, so the total links are 229, which means that there are fewer Twitter accounts in the social network on tourism marketing, but they have a few close relationships by sharing information. The research can map the social network of communicators of tourism marketing using Twitter data. The network has a complicated pattern, including one independent network and some connected networks. Some mediators connect each network and can control the information flow of tourism marketing. More communicators are getting the information than the ones providing it, which means that there is likely to be the dependence of information among communicators that can cause an obstacle and distortion of the information flow system, especially in the independent network.

Purpose: A network meta-analysis was conducted to assess the comparative effects and ranks of repositioning for pressure ulcer prevention in adults. Methods: A network meta-analysis was performed in a frequency method, using the "netmeta" package of R software version 4.1. The effects of repositioning intervention were confirmed by the odds ratio. The comparative ranking of the repositioning effects was confirmed using the cumulative probability (P-score). Results: Seven intervention studies were included in this study. Based on the P-score, the use of the repositioning system was ranked as the most effective among all interventions (P-score 78.7%). Next was 3~4-hour repositioning combined with memory foam mattress use (P-score 77.2%), use of wearable sensor (P-Score 61.4%), 2-hour repositioning combined with memory foam mattress use (P-score 59.1%), 2-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%), and 4-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%). Conclusion: This study provides information on the relative comparative value of various repositioning interventions to prevent pressure ulcers using network meta-analysis. This is expected to be useful for nurses' decision-making when applying repositioning interventions in clinical practice
