This prompted NANNNA leadership to initiate and conduct support programs for nurses especially those on the frontline of care. This project evaluates the effectiveness of the support programs conducted by NANNNA during the early surge of COVID-19. The Centers for Disease Control’s (CDC’s) Framework for Evaluation in Public Health guided this evaluation. Focus group discussion and online survey was utilized to gather data. While 19% of respondents reported being diagnosed with COVID-19, the majority (81%) were not. About 44% of respondents had family members who were diagnosed with COVID-19, while 18% reported loss of a close family member due to COVID-19 complications. Most respondents reported that the program was impactful in information sharing as well as significant in helping them feel connected with other nurses. Hence, this subsequently enhanced their support networks, provided emotional and spiritual support. Survey results revealed that NANNNA support programs had positive effects in helping members mitigate the fear, anxiety and uncertainty experienced during the surge of the COVID-19.展开更多

Recent efforts have been dealing with the problem of learning from very large datasets. This paper reviews the most commonly used formulations of support vector machines for regression (SVRs) aiming to emphasize its usability on large-scale applications. We review the general concept of support vector machines (SVMs), address the state-of-the-art on training methods SVMs, and explain the fundamental principle of SVRs. The most common learning methods for SVRs are introduced and linear programming-based SVR formulations are explained emphasizing its suitability for large-scale learning. Finally, this paper also discusses some open problems and current trends.展开更多

The program incorporates “Simple exercises to replace lymphatic drainage” based on lymphatic flow. The purpose of this study was to consider the feasibility of continuing this program. Methods: The participants were patients in the early stages of secondary lower-limb lymphedema after gynecological cancer surgery and lymphedema therapists with more than five years of experience. Patients continued self-care at home after being briefed on the program, and they were analyzed on their self-care continuity status one month later based on a self-administered questionnaire survey and self-care notes. We interviewed the lymphedema therapists about this program to discuss the feasibility of continuing it and obtain feedback. Results: The patients who participated in the study were six women who underwent surgery with lymph node dissection for gynecological cancer. The therapists were five nurses and one occupational therapist. The patient understood the importance of all items in the self-care. “Observation,” “Touching,” and “Skin care” were relatively easy to continue. “Lymph drainage” and “Exercise” were continued with “Simple exercises to replace lymphatic drainage”. “Other exercises” were able to continue by adding distance and time to daily activities. Furthermore, “Measurement” and “Recording” became a burden and were difficult to continue. Nonetheless, this program was generally approved by the lymphedema therapists. They also pointed out the content and format of the self-care notes as improvements. Conclusions: We found that the self-care supporting program that incorporated “Simple exercises to replace lymphatic drainage” might be feasible to continue self-care for patients with early stages of secondary lower-limb lymphedema. Furthermore, we found that we needed to improve the “Measurement” and “Recording” sections of this program.展开更多

In the proposed algorithm, linear programming is employed to solve the optimization problem of classification to decrease the computation time and to reduce its complexity when compared with the original model. The adjusted punishment parameter greatly reduced the classification error resulting from asymmetric distributed samples and the detailed procedure of the proposed algorithm is given. An experiment is conducted to verify whether the proposed algorithm is suitable for asymmetric distributed samples.展开更多

The rigours of manual design of the conventional water treatment plants are easily eliminated with the use of softwares as in the case of DSS. Therefore, this paper focuses on the development of a Water-DSS for design of treatment plant in Karkala Town, Udupi District of India. A four-decade population projection was made using the baseline data of 1971 till date. The manual computation for water demand, unit operations and adjoining facilities was carried out and later coded in C-programming language for development of a DSS for easier design and process selection. Data validation was done and results from the two approaches were compared. With the C-programming technique, a decision support tool for design and process selection of drinking water treatment plant using conventional method has been developed and named Water-DSS1. The designed tool is simple, accurate, flexible, efficient and universal, easily adaptable to any similar conventional treatment plant. Water-DSS1 is thus recommended for general use in ultimately alleviating water supply challenges.展开更多

It takes the innovative service program based on an IC2 conceptualized program at Shanghai Jiao Tong University Library(thereafter abbreviated as SJTUL) as a concrete example to elucidate the merit of such an endeavor. Specifically, this paper discusses the particular development background, overall objectives and service contents of the IC2 motivated program at SJTUL. By presenting a detailed account of some of the key measures, major achievements and also possible future directions of library service development under the guiding principles of SJTUL's IC2 program, these authors hope that its innovative library practice may serve as a reference for other academic librarians to gain some inspirations for their own parallel service innovations or refinement focused on subject-oriented library liaison service to their constituents and parent institution's curricula and research projects.展开更多

Methods: A retrospective analysis of the complete clinical data of 340 patients undergoing in vitro fertilization embryo transfer in the Department of Reproductive Medicine, Jingzhou Central Hospital from September 2016 to July 2018. These patients were divided into group A and B according to the luteal support program. We compared the clinical outcomes of the two corpus luteum preparations by comparing the laboratory parameters of the two groups of patients with clinical pregnancy indicators. Results: We found there was no significant difference in the results of general conditions in the two groups of patients, such as infertility age and duration, body mass index (BMI), basal follicle stimulating hormone (FSH), basal luteinizing hormone (LH), basal estrogen (E2) levels, the endometrial thickness, the number of transplanted high-quality embryos on the day of transplantation and so on (P > 0.05). We found that the implantation rate (32.55%), biochemical pregnancy rate (53.57%), and clinical pregnancy rate (51.78%) in group B were significantly higher than those in group A (25.26%, 35.11%, and 34.66%, respectively) (P 0.05). Conclusion: We conclude that patients who are scheduled for frozen embryo transfer use progesterone vaginal sustained release capsules combined with luteal progesterone luteal support, have improved clinical pregnancy rates.展开更多

Therefore, family peer education program has been developed in Japan following the U.S. and Hong Kong. We aimed to identify program components that families recognize which would provide suggestions in modifying the program. We used qualitative and inductive study design. Data were collected through group interviews for six family research participants. We coded the data to focus on relationships between program components, program processes, and impacts. Data Analysis resulted in seven assumptions based on causal relationships and three types of program components: program form, learning style and facilitation skills. The program form is family-led peer group, closed-membership, 5 times per course, and small group. The learning style is combination of textbook and experiential knowledge, family peer learning, and sharing experiences. The facilitation skills are group work focusing on strengths of family members, the acceptance of emotional disclosure, omotenashi, and teamwork skills.展开更多
