Fast Constructions of Quantum Codes Based on Residues Pauli Block Matrices

We demonstrate how to fast construct quantum error-correction codes based on quadratic residues Pauli block transforms. The present quantum codes have an advantage of being fast designed from Abelian groups on the basis of Pauli block matrices that can be yielded from quadratic residues with much efficiency

An Estimation of Production Coupling Effects of Direct Payments for Rice Farms

This study provides empirical estimation results concerning the degree of production coupling for the fixed and variable direct payment program designed for stabilizing rice farmers’ income. Based on a set of producer’s expectation formulations, we analyzed the impacts of direct payments on the rice cultivation area, using a panel data estimation technique. To consider the risk preference of farmers, we used an expected utility maximization model under the expected utility hypothesis. Also, we explicitly included a variable capturing truncated variance of rice price related to variable direct payments. Our estimation results indicate that both fixed and variable direct payments tend to have production coupling effects. Specifically, we found that the production coupling effect of variable direct payments was higher than that of fixed direct payments. We also discovered that the rice cultivation area has been affected by these direct payments via the insurance effects (variable direct payments) and wealth effects (fixed direct payments)

Characteristics of Thin-Film NTC Infrared Sensors

Characteristics of thin-film NTC infrared sensors fabricated by micromachining technology were studied as a function of the thickness of membrane. The overall-structure of thermal sensor has a form of Au/Ti/NTC/SiO x /(100)Si. NTC film of Mn 1.5 CoNi 0.5 O 4 with 0.5 µm in thickness was deposited on SiO x layer (1.2 µm) by PLD (pulsed laser deposition) and annealed at 600-800 • C in air for 1 h. Au (200 nm)/Ti (100 nm) electrode was coated on NTC film by dc sputtering. By the results of microstructure, X-ray and NTC analysis, post-annealed NTC films at 700 • C for 1 h showed the best characteristics as NTC thermal sensing film. In order to reduce the thermal mass and thermal time constant of sensor, the sensing element was built-up on a thin membrane with the thickness of 20-65 µm. Sensors with thin sensing membrane showed the good detecting characteristics

Cancer-Oriented Comprehensive Nursing Services in Republic of Korea: Lessons from an Oncologist’s Perspective

Background and objectives: As is well known, cancer patients require extensive medical attention as they undergo surgery, chemotherapy, radiotherapy, and supportive care. The importance of high-quality cancer-directed nursing, combined with precision medicine, to maximize their survival outcomes and help them achieve a better quality of life cannot be overemphasized. In this context, we offered a new cancer-oriented comprehensive nursing system to our inpatients and reviewed its clinical outcomes in comparison with those from the preexisting general cancer ward. Materials and Methods: From March 2019 to February 2020, a total of 102 cancer patients and 42 nurses were enrolled in this pilot study. We aimed to analyze their performance in three main categories: structure, process, and patient/nurse outcomes. Results: First, structural (nurse staffing and environment) upgrades were installed in the cancer-oriented comprehensive nursing ward, including an improved nurse-patient ratio (1:8 in the comprehensive ward as compared with 1:14 in the general ward), wider space between beds (1.5 m versus 1.0 m), fully automatic beds with fall prevention sensors, etc. Second, the nursing process was improved (missed care 0.1 event/month vs. 1.3 event/month). Third, both patient and nurse outcomes showed preferable results in the comprehensive ward. The patient satisfaction level was higher in the comprehensive nursing ward than in the general ward (willing to revisit: 91.7% and 78.4%, respectively; willing to recommend to others: 95.0% and 76.8%, respectively). Pressure ulcers, as a patient safety indicator, were also decreased (0.3 events/month vs. 0.8 events/month). However, the fall incidence was similar in both groups (1.6 events/month vs. 1.5 events/month). In terms of nurse outcomes, turnover intention was stabilized and nurses’ job satisfaction in the comprehensive ward was superior to that of their counterparts. Conclusions: Our study was a pilot study to demonstrate that cancer patient-oriented comprehensive nursing services can be helpful in improving the quality of cancer treatment and nurses’ job satisfaction. Continued interest in and efforts to improve nursing care delivery are also crucial in achieving and maintaining the best possible cancer patient care
