The rapid change in almost every area of science at the turn of the 21st century have also affected libraries and information centers. Whatever the change, from the library users' perspective, the functions provided by the library, is perceived as "service" and the satisfaction of the users can only be measured by the quality of the service. The library and information center acting as a service provider aims to establish a framework for improvements in services by focusing on the user's perspective on service quality and classifying the factors that contribute to service quality. This study adopted the LibQUAL+ model, which is derived from SERVQUAL model for measuring quality of service in the field of Service Marketing.

Background: With the rise in global mobility, aircraft indoor air quality has become a significant public health concern. This study focuses on the health implications of increased travel and bleed air-air drawn from aircraft engines for cabin pressurization and air conditioning. Objectives: This research aims to review the potential health effects related to exposure to aircraft cabin air, particularly the effects of bleed air during fume events. Methods: We conducted a literature review of existing studies on aircraft cabin air quality. We focused on both the immediate and health effects of exposure to cabin air, particularly those related to bleed air contaminants. Results: The review found a possible link between exposure to aircraft cabin air and certain health issues, especially in cabin crew and frequent flyers. There was an increased incidence of respiratory and neurological symptoms related to bleed air exposure. However, the cumulative health effects of frequent air travel remain inconclusive due to limited data. Conclusions: This study highlights the need for improving air quality in aircraft to protect public health. While further research is needed to understand the cumulative effects of frequent air travel, the reduction of exposure to bleed air contaminants should be a priority. These findings underline the need for regulatory changes and technological improvements in aircraft cabin air quality.

Background: Increasing numbers of super-elderly patients (>80 years old) with cancer now require microvascular-free tissue transfer. The objectives of this study were to evaluate potential applications of microvascular tissue transfer in this patient population, and post-surgical changes in quality of life. Methods: The records of cancer patients 80 years or older who had undergone microsurgical tissue transfer were retrospectively reviewed. Structured interviews were conducted with patients and family caregivers after surgery, and the patients' quality of life was qualitatively assessed. Results: The study cohort consisted of seven patients with a mean age 87.6 years (range, 81 to 95). Wound and medically-related complications were minimal. During the patient interviews, eight of the nine respondents reported remarkable improvements in quality of life following surgery and expressed a high level of satisfaction with their surgical results. Conclusions: Our study showed that microsurgical reconstruction performed in super-elderly patient not only appropriately repairs post-oncologic defects but also significantly improves the patients' quality of life.

Purpose: The aim of this study was to evaluate the effects of the group therapy on psychological symptoms and quality of life of patients with early stage breast cancer. Methods: This study was performed on 16 breast cancer patients who completed treatments. The total group therapy program involved a weekly session of 2-3 hours, for 16 weeks. The group therapy sessions were given to women in the oncology department by a clinical psychologist and also given training sections by the different professional teams. All the required assessments for the study were performed after and before 16 week group therapy intervention. Results: Initially we had taken 21 women but 16 participated in all therapy programs and submitted questionnaires. The mean age was 47.8 years. There were significant differences between before and after group therapy program. Anxiety, depression, and distress showed significant improvements. Hopelessness scale was detected at the border of significance. There was no change in sleep problems and quality of life. According to the analysis of correlation, considering the age factor and year of diagnosis, there was found no statistically significant relationship between anxiety, distress, depression, hopelessness, sleeplessness, and quality of life. Conclusions: This pilot study demonstrated that brief, predominantly group therapy is feasible for patients with breast cancer and, also it may be helpful to cope with emotional and physical distress.

Intensive selection for muscle development and against fat deposition in pigs during the last 50 years has contributed to the increased incidence of porcine stress syndrome (PSS) and pale soft exudative pork (PSE). Genetics, nutrition and management, preslaughter animal handling, stunning, dehairing and carcass chilling influence the incidence and magnitude of the PSE condition. The normal incidence of PSE has been reported to range from 10 to 30%, but in some isolated instances is up to 60%. The elimination of halothane-positive pigs in breeding programs has reduced PSS and PSE. Further improvements in meat quality by terminal sire evaluation and selection can be achieved within halothane-negative populations because around 20% of the variation in meat color and water binding capacity seems to be genetically related. Pre-slaughter handling on the farm, during transit to the packing plant and at the packing plant can greatly influence the meat quality, contributing 10 to 25% of the variation. An effective stunning method, skinning instead of scalding/dehairing and rapid post-slaughter chilling further reduce the incidence of PSE pork. In addition to proper care and handling a carcass-merit based marketing system, that reflected the value differential between desirable and undesirable meat quality in the pricing system for pigs, would provide a great incentive to change pork production systems in order to improve meat quality, thus improving the image and usefulness of pork as food.
