Dietary intake in adults on hemodialysis compared with guideline recommendations

BackgroundClinical practice guidelines of dietary management are designed to promote a balanced diet and maintain health in patients undergoing haemodialysis but they may not reflect patients’ preferences. We aimed to investigate the consistency between the dietary intake of patients on maintenance haemodialysis and guideline recommendations.MethodsCross-sectional analysis of the DIET-HD study, which included 6,906 adults undergoing haemodialysis in 10 European countries. Dietary intake was determined using the Global Allergy and Asthma European Network (GA2LEN) Food Frequency Questionnaire (FFQ), and compared with the European Best Practice Guidelines. Consistency with guidelines was defined as achieving the minimum daily recommended intake for energy (≥ 30 kcal/kg) and protein (≥ 1.1 g/kg), and not exceeding the maximum recommended daily intake for phosphate (≤ 1000 mg), potassium (≤ 2730 mg), sodium (≤ 2300 mg) and calcium (≤ 800 mg).ResultsOverall, patients’ dietary intakes of phosphate and potassium were infrequently consistent with guidelines (consistent in 25% and 25% of patients, respectively). Almost half of the patients reported that energy (45%) and calcium intake (53%) was consistent with the guidelines, while the recommended intake of sodium and protein was consistent in 85% and 67% of patients, respectively. Results were similar across all participating countries. Intake was consistent with all six guideline recommendations in only 1% of patients.ConclusionPatients on maintenance haemodialysis usually have a dietary intake which is inconsistent with current recommendations, especially for phosphate and potassium.

Development of green building maintenance information system for electrical components based on ministerial regulation

Green building maintenance is a series of structured, complicated and complex work. Maintenance of building components can support the achievement of building reliability requirements, which are safety, comfort, health and convenience.

The result of this research revealed that green building maintenance guideline in a web-based information system will help to reduce the problems and damages that often occur in electrical components, thereby reducing the harmful impacts that can occur in a green building and its surrounding environment.

Identifying preventive maintenance guideline for a combine harvester with application of failure mode and effect analysis technique

The objective of this research was to study a risk assessment of the rice combine harvester using FMEA technique implementation and suggested the procedures to maintain the parts of the rice combine harvester by analyzing the causes of risk assessment of FMEA. The FMEA was also applied to specify failure causes and effects that occurred in the rice harvester. The obtained data were calculated for a risk priority number (RPN) and then sorted to be a descending order. The high RPN part was analyzed for the causes and effects and then suggested a preventive maintenance in near future. The results revealed that the highest RPN of 576 was found when a chain surface was considered and also showed the maximum risk among the considered parts in the rice combine harvester. While, the lowest RPN of 144 was found when a rice sieve part was considered but this RPN was still higher than that of 100 RPN which was required to specify the preventive maintenance.

Key Criteria for Post-Reconstruction Hospital Building Performance

Quality continues to be such an issue in humanitarian projects and it is because the model of quality control in normal business is driven by its customers however, does not operate in the aid sector. Evaluation and monitoring in every building life cycle in reconstruction process is important to increase the quality of the aid project. Among all types of public buildings and facilities, hospital is considered as one of the most essential assets in disaster management. However, there is no list of criteria available yet to evaluate post-disaster hospital building performance. The objective of this study is to identify the key criteria for hospital building. A total of 116 respondents are collected from experts of built environment field and high level position staff in grade B hospital in the capital city of Aceh province, Banda Aceh. After conducting Cronbach’s alpha coefficient test and factor analysis, total twenty-six criteria were found reliable and valid. Subsequent with the relative importance indices (RII) analysis, this study has come out with the top-fifteen most important criteria for post-disaster reconstruction building performance as in order: safety, health, control of environment impact, easiness, accessibility, engineering, building quality, staff and patient environment, comfort, functionality, building form and material, operational maintenance guideline, local institution capacity, architecture, disaster resilience, and the last criterion is sustainability. It is recommended to use these criteria for hospital building performance evaluation especially in disaster prone area.

Design Support for Maintenance Tasks using TRIZ

Design for Maintenance is a method to optimize maintenance activities during the design process. To help maintenance engineers, the chair Maintenance Engineering at the University of Twente has set up a list of 37 guidelines. However, these guidelines only state the goal that should be achieved, but do not define the actions that should be taken to solve maintenance-related problems during the design phase. TRIZ is a product and process innovation method that uses various tools that propose paths to possible innovations and solutions. As such, TRIZ promises it could be a useful addition to the existing set of 37 maintenance guidelines. In this research the compatibility of TRIZ and maintenance guidelines is explored using a 3 stage research plan. Firstly, applicable guidelines are linked to TRIZ methods. In a second step these links are grouped and generalized so not every maintenance guideline also needs a unique TRIZ strategy. Finally a roadmap is presented that helps during Design for Maintenance activities in solving maintenance problems with the support of TRIZ tools.

정비절차 생성을 위한 자동 분해/조립절차 연구

The purpose of this research is to propose a maintenance support system for deciding assembly sequence of the product and appropriate tools that are used to assembly and disassembly of parts in the product when geometric properties of the product. The digital maintenance system (DMS) is developed to generate the maintenance guideline and the initial experiment is conducted especially for an underwater weapon system with cylindrical structure. DMS considers four factors to find the efficient assembly and disassembly procedure automatically: (1) assembly tree, (2) properties of each part, (3) distance from the center of the product, and (4) volume. Based on the factors, DMS simulate the movement of each tool virtually and the properties of tools are investigated to find an appropriate tool for using assembly and disassembly of each part in the product. The proposed approach integrates modeling, simulation, data configuration, and virtual reality to allow a development of preliminary maintenance guidance.
