Effect of Light Level on Stress, Anxiety, Psychological Well-being in Pregnant Women: Randomized Placebo-controlled Study

To determine the effect of light level on stress, anxiety and psychological well-being in pregnant women. This research was planned as a single-blind, randomized controlled experimental type study by comparing separate groups as experiment-placebo control. Data will be collected using the Introductory Information Form, Psychological Well-Being Scale, Perceived Stress Scale (ASÖ/PSÖ-14), and State-Trait Anxiety Inventory (STAI). The effect of two different amounts of light on pregnant women will be evaluated.

The Effect of Automatic Massage Applied to Healthcare Workers on Pain, Fatigue and Psychological Well-being

To determine the effect of automatic massage applied to healthcare workers on pain, fatigue and psychological well-being. This research is planned as a pretest-posttest type study. It will be held in the Osmaniye State Hospital maternity ward. The application will be applied by one person in the rest room. Data will be collected using the Introductory Information Form, Psychological Well-Being Scale, Perceived Stress Scale (ASÖ/PSÖ-14), State-Trait Anxiety Inventory (STAI), and Piper Fatigue Scale.

The Effect of Pregnant-controlled Sacral Massage on Mothers' Labor Pain, Perception, Process and Midwives' Satisfaction

Our study aims to determine the effect of pregnant-controlled automatic sacral massage on mothers' labor pain, perception, process and midwives' satisfaction. The research was planned as a randomized controlled experimental study. A total of 112 women, 56 pregnant women in the experimental and control groups, will be included in the study. In this project, an automatic massage device will be used during the active phase (when the cervical opening is between 5-6 cm and 10 cm) and a massage device in line with the pregnancy-controlled sacral massage application protocol. Pregnant women are followed throughout the active phase of labor and indicators reflecting labor pain, progress of labor, and the health status of the mother and the baby are used with the "Individual Identification Form", "Visual Comparison Scale", "Labor Monitoring Form", "Mother's Birth Perception Scale (ADAS)". The satisfaction of midwives will be evaluated with the "Evaluation of Satisfaction Status of Midwives Form".

AbstractIn this study, an optimization methodology is followed in order to explore better form of heat sinks which improve thermal performances. Optimum designs of plate fin heat sinks (PFHSs) and modified shaped plate fin heat sinks (MS-PFHSs) are numerically investigated. The objective functions are minimizations of base plate temperature, entropy generation and mass. For both PFHSs and MS-PFHSs, optimization variables include inlet velocity (Vin), fin height (Hfin), and number of fins (NL). Plate fin form is adjusted for MS-PFHSs by adding two optimization variables: the rib height (Hrib) and the number of patterns in the flow direction (Wp). For the multi-objective optimization problems, the maximum base plate temperature limit (Tbase<70 °C) is used. The multi-objective genetic algorithm (MOGA) is used to solve optimization problems, and three-dimensional parametric models for numerical optimization work are examined using the finite volume approach. The flow is steady, incompressible, and turbulent, and heat transfer in the heat sink is represented by conjugate heat transfer (CHT). It is shown that MS-PFHSs outperform in terms of the analyzed objective functions. For the optimum designs, Tbase values of MS-PFHS and PFHS are 60.23 °C and 65.25 °C, respectively, while the mass values are same. The results also indicate that Tbase obtained in the optimum design of MS-PFHS is 7.69% lower than that obtained in the optimum design of PFHS.

Optimization of cutting parameters in manufacturing of polymeric materials for flexible two-phase thermal management systems

作者: Ordu, Muhammed ; Basar, Gokhan ; Der, Oguzhan

AbstractThis research study with an extensive literature review represents a comprehensive multi-criteria analysis for optimizing the cutting parameters in the manufacturing of flexible two-phase passive thermal management systems (FTP-TMS) using thermoplastic materials. Recognizing the critical role of thermoplastics in FTP-TMS due to their inherent flexibility and lightweight properties, this research focuses on the precision cutting of polypropylene, polyethylene, and polyvinyl chloride using CO2 laser technology. The study is structured into three distinct phases. Initially, an experimental setup was conducted to cut 2 mm thick thermoplastic materials with varying power and cutting speed parameters. Subsequently, the SWARA method was employed to weight the criteria, followed by the application of seven different multi-criteria decision-making (MCDM) methods for optimization. The final phase involved a detailed analysis of the outputs, including ranking, correlation, and sensitivity analyses. The findings indicate that cutting polypropylene with a 90 W power setting and a speed of 15 mm s−1 yields the most optimal results. This study fills a significant gap in the existing literature by providing a dedicated analysis for thermoplastics in FTP-TMS manufacturing. The insights gained are pivotal for standardizing manufacturing practices and enhancing the design and fabrication of flexible thermal management solutions, offering substantial benefits to sectors like electronics, aerospace, and automotive industries.
