The need for environmental education, which incorporates the life cycle concept into the learning program, will become increasingly greater all over the world. In the present study, an e-learning system, which is made up of 3 parts including text-based learning materials, quizzes to review the content of the learning materials and CO<sub>2</sub> emission simulation, was designed and developed with the purpose of supporting environmental learning. Targeting a wide range of people, the operation period of this system was 1 month. Based on the results of questionnaire survey for users, it was evident that the quiz function and the simulation function of CO<sub>2</sub> emission contributed to the efficiency in environmental learning, and the format of the e-learning system was effective and helpful for environmental learning. Additionally, with the users’ awareness related to environmental conservation before and after using the system, significant changes in awareness were seen in areas such as behavioral intention, sense of urgency and sense of connection. Furthermore, as it was revealed that 62% of the total access numbers were from mobile devices, it was effective to prepare an interface optimized for mobile devices enabling users to use the system from their smartphones and tablet PCs. 展开更多

LIC cycle life degradation can be described by an Arrhenius equation. This study performed cycle life testing at a constant temperature but varied cycle current. The results were described by an Arrhenius equation relying upon the number of cycles and a constant, which was determined by cycle current. Using mathematical derivations and experimental results, the researchers quantified the effects of activation energy and temperature upon this constant. Because cell temperature is nearly constant during cycles, it was deduced that elevated cycle current decreases activation energy. This lower activation energy then accelerates degradation. Thus this research demonstrates that cycle current ages LICs through its effects on their activation energies. 展开更多

Despite the global impact of TB and treatment received, a gap persists between treatment and quality of life of the patients especially in resource limited countries. This study therefore evaluated the health related quality of life of TB patients and the different factors influencing their quality of life at the post intensive phase of their treatment in the Fako division of the South-West Region of Cameroon. <b>Methods: </b>A hospital based cross sectional study was carried out in 4 tuberculosis treatment centers, namely two regional (Buea and Limbe) and two district (Tiko and Muyuka) hospitals in Fako Division between June and July 2017. One hundred and sixty-seven TB patients were enrolled in the study and relevant information from them was gathered using the SF-36 questionnaire. Various aspects such as their perception of the disease, their socio-demographics and socio-economics conditions were evaluated. <b>Results: </b>Of the 167 participants enrolled in the study, 95 (56.9%) were male and 72 (43.1%) were female. One hundred and thirty-three (79.6%) of the 167 participants were affected by pulmonary tuberculosis and 34 (20.4%) by extra-pulmonary tuberculosis. Fifty-five (32.9%) were HIV positive and 90 (53.9%) had been receiving treatment for 4 - 6 months, 73 (43.7%) for 1 - 3 months and 4 (2.4%) for 7 - 9 months. The lowest and highest scores were recorded on the role limitation due to emotional problems scale (30.54 ± 35.36), and on the social functioning scale (47.68 ± 16.33) respectively. There was a significant difference (p = 0.021), between pulmonary and extra pulmonary tuberculosis (49.15 ± 16.08 vs. 41.91 ± 16.25) on the social functioning. Financial difficulty restraining drug collection affected the general health perception (p = 0.003), vitality (p = 0.007), emotional well-being (p < 0.001) and social functioning (p = 0.05) of the patients.

The review was conducted according to PICo (Participant, area of Interest, and Context). Keywords identified were: “nurse” AND “end-of-life care” (“dyingcare” OR “‘deathcare”, OR “near end stage of life care” OR “palliative care” OR “hospice care” OR “comfortable care in near death” OR “quality of dying patients care”), AND “nurses”. The database searched through PubMed, ProQuest, Google Scholar, Web of Science and SCOPUS. The searching inclusion criteria were limited to English and Chinese language studies about nurses’ end-of-life care from 2010 to 2019, yielding 258 English language articles and 2Chinese language articles. Results: A total of fifteen articles were selected based on inclusion criteria. Two subjects were obtained from the results that related to nurses’ care during the process of end of life: 1) Nurses’ demographic factors;and 2) Modifiable factors. Nurses’ demographic factors were age, years of work experience, level of education and experience of the death of a family member/friend. Modifiable factors included knowledge, attitude, confidence, relationship, environment and resources, communication, nursing activities, philosophy and culture of care, skills and training. These factors were explored in various areas and majority of the studies had been conducted in public government hospitals. Conclusion: The major power ability of care was observed in nurses who acted the significant part in caring for the terminally ill during the dying process. Caring for dying patients was related to many factors which could affect the fabric of nursing care at the end stage of life. The elements found in this review could lead to recommendations with implications for nursing practice so as to improve and enhance end-of-life care. Some factors could be considered like predictors affecting nursing practice for chronical ill patients in 展开更多

Background: Early life stress is a significant public health problem associated with increased rates of psychiatric disorders, especially those related to drug abuse. Objective: To identify the prevalence of early life stress in drug users, to compare the intensity of trauma in alcohol and crack users, and to relate the power of injury to the severity of drug dependence. Method: Cross-sectional analytical study with a sample of 105 alcohol and crack users treated by an outpatient service. The instruments for data collection were sociodemographic data questionnaire, the Mini-International Neuropsychiatric Interview, and the Severity of Dependence Scale. The categorical variables association was analyzed using the Chi-squared test, considering p Results: High prevalence of early stress and severity of dependence were identified, with higher rates among crack users. The early stress revealed in the Alcohol group high rates of emotional (88.7%) and physical (94.3%) neglect and in the Crack group significant frequency of physical (61.5%) emotional abuse (51.9%), sexual (46.2%), and emotional (78.8%) and physical (90.4%) neglect. Crack users are 2.6 times more likely to have been emotionally abused, and 2.1 times more likely to have been sexually abused during childhood when compared to the alcohol group. Conclusion: Early stress was prevalent with significant intensity in drug users, and evaluation of this problem is essential for a better understanding of these disorders. 展开更多

Present article sketches out major climate induced changes in marine, aquatic and terrestrial life. Few important biomarkers such as ecological, meteorological, socioeconomic, thermal, biophysical and biological, behavioral markers of climate change and global environmental stress have been highlighted to predict the future challenges and finding appropriate solutions. Though, so many climate change induced effects are visible but few unpredictable effects may be seen in future. Therefore, all such effects have been acknowledged, and tried to find appropriate solutions. Most visible effect is collection of high amounts of carbon dioxide in the atmosphere which is responsible for green house effect and causing natural calamities round the globe. It is not only jeopardized the survival of terrestrial, fresh water animals mainly planktons, bottom dwellers;coral reefs, algae, fish fauna in marine environment belong to different taxon but also responsible for disruption of ocean’s food web due to non-assimilation of extra carbon dioxide by the ocean water. There is a sharp decline in fresh water and sea shore micro-flora and micro-fauna. Other major visible effects are loss of biodiversity, depletion of forests, land degradation, severe floods and draughts. On other hand sudden changes in weather conditions causing irreparable devastations due to hurricanes and typhoons, storms, lightening, earthquakes and tsunamis are normally on rise. Both economic and ecological breakdowns are occurring more frequently which are more impactful and persistent. Climate change is major human health stressor;it is making fragmentation of socio-cultural bonds and reducing fertility of soil finally crop production. Climate change is imposing non-adaptive forced human migration, territorial conflicts, decreasing ecosystem productivity, disease out breaks, and impelling unequal resource utilization. 展开更多

In the previous paper <a href="#ref.1" target="_blank">[1]</a>, the application of the general thermodynamic theory was considered to biological systems. The nature of living matter has been presented from the mesoscopic to the macroscopic point of view, for different time scales (ontogenetic and phylogenetics). Herein, we continue with this application, and present three characteristics of life in the form of statements or postulates. The first characteristic describes the probability of survival against aging. In particular, the behaviour of life is shown as an independent mode of aging. The second characteristic refers to the adaptation of the species according to the environment. The relationship between the phenomenon of organic homeostasis and the origin of the clinical parameters that define health is highlighted. And finally, the third characteristic applies the principle of negentropy to describe evolution. A representative model is given as an example of each postulate. 展开更多

Background: Nowadays, a substantial number of women spend more than one-third of their lives in the postmenopausal period. It is characterized by a marked decrease in the production of estrogen, which leads to urogenital atrophy. The symptoms stemming from vulvovaginal atrophy and the lower urinary tract are currently referred to as the Genitourinary Syndrome of Menopause (GSM), which can have a negative impact on the quality of life (QoL). Estrogen replacement is the ideal treatment for GSM, and vaginal administration is the most recommended. Objective: To assess the impact of the use of topical vaginal estriol on the quality of life (QoL) of postmenopausal women with lower urinary tract symptoms (LUTS). Methods: This is an interventional, prospective study, performed in 49 women at the Antonio Pedro Hospital, at the Universidade Federal Fluminense, in Niterói, Brazil, from August 2014 to April 2015. It included postmenopausal women with lower urinary tract symptoms who were not using any estrogen hormone therapy, and it excluded those with contraindications for the use of estriol. A specific questionnaire on QoL and urinary tract symptoms, the King’s Health Questionnaire (KHQ), which identifies LUTS and assesses to what extent those symptoms interfere with QoL, has been used as a research tool. Results: The average age was 62.24 years. Urinary urgency and urge incontinence were reported by 91.8% of women. The average scores of the domains of the KHQ decreased in the domains General Health Perception (before: 46.42 ± 21.65;after: 40.81 ± 22.64), Incontinence Impact (before: 74.82 ± 27.66;after: 41.49 ± 30.83), Role Limitations (before: 43.20 ± 32.80;after: 21.09 ± 24.71), Physical Limitations (before: 38.09 ± 32.09;after: 14.62 ± 24.20), Social Limitations (before: 30.38 ± 28.75;after: 12.62 ± 19.85), Emotions (before: 43.31 ± 32.96;after: 20.18 ± 26.41), Sleep/Energy (before: 41.48 ± 37.74;after: 15.98 ± 23.31) and Severity Measures (before: 48.02 ± 24.68;after: 22.31 ± 20.25).

Almost one-third of young people consider acne to be a major problem/burden. Less than half of acne diagnoses are made by a physician, and acne is often self-managed. Objective: We aim to find the prevalence of acne among different age groups, treatment seeking behaviors and sources of knowledge about acne treatment. We also aim to determine impact of acne vulgaris on quality of life and psychology of patients. Design: A cross-sectional study. Setting: Jordan university hospital, Amman, Jordan. Subjects: Patients aged 15 - 35 years old who attended the family medicine clinic in Jordan University Hospital. Intervention: A self-administered questionnaire, consisted of three major parts, distributed during the period between August 2019 and October 2019. Results: Upon analyzing the data, 153 out of the 300 participants were found to have suffered or were still suffering from acne with a prevalence of 45%. The mean age at which the acne started was 16.20. There was a significant correlation between severity of acne and impact on life. More than half of the affected participants sought doctor help to treat their acne;patients depended on many sources of information to manage their acne. The majority of them reported the dermatologist as their source of information. Patients tended to use different methods of treatment to manage their acne. The cleanser was the most commonly used methods of treatment. Conclusion: Our article demonstrates that acne is a prevalent distressing problem among adolescents;it affects patients’ quality of life. Different modalities of treatment and sources of information were sought by patients. As family doctors, we emphasize the need for accessible, accurate, community-based education on the modalities of treatment of acne, and the importance of prompt medical attention toward its effect on quality of life. 展开更多

Much research has highlighted the aging process as a global, multi-faceted issue, focusing on modifiable factors that can improve physical health and psychosocial well-being in late life. This is particularly true for both developed and developing countries, which are likely to face long-term issues in health and psychosocial care as the aging of their population increases. Within the theoretical framework of successful aging and developmental psychology, this paper aims to review recent advances in our knowledge of middle and late-life well-being in order to better understand the role of well-being and spirituality/religiosity across adulthood. The results of the selected studies allow us to conclude that subjective, hedonic, and eudemonic well-being and religious practices are significant determinants shaping the overall psychological well-being, life satisfaction, and social functioning of the older population. Limitations and implications of the study will also be discussed. 展开更多

In this current paper, the exposure time effects on four endocrine disruptors and teleost fishes were evaluated using the reduced life expectancy (RLE) model based on the effect concentration (EC<sub>50</sub>) of available literature published. The result on the regression analysis over different exposure times has demonstrated that the EC<sub>50</sub> of hepatic biomarkers falls with increasing exposure times in a predictable manner. The slopes of the regression equations reflect the strength of the toxic effects on the various teleost fish. The EC<sub>50</sub> reduction over time can be interpreted based on the bioconcentration process, which can be used to understand transfer routes of the compounds from water to fish body. RLE model also provides useful information in assessing the toxic effects on fish life expectancy as a result of the occurrence of compounds. 展开更多

It endeavors to address social and/or emotional concerns as well as any symptoms or functional problems related to the teeth and jaws from the patients view point. The difficulty of utilizing any one standard evaluation tool to determine how the patient feels about problems with malocclusions or arising from them, led to the development of this construct/theory. <strong>Aim:</strong> To evaluate the impact of malocclusion on the socio-functional and psychological wellbeing of persons 7 - 25 years old. <strong>Method: </strong>100 patients within the ages of 7 - 25 years who visited the Orthodontics Unit of the Oral Health Directorate of Komfo Anokye Teaching Hospital (KATH), Kumasi, were conveniently sampled and surveyed. Participants were given questionnaires to assess the effects of malocclusion on their Oral Health Related Quality of Life and also to determine if their educational status had any influence on the impact of malocclusion on their oral health related quality of life. <strong>Results:</strong> The modal age of the participants was 10 - 15 years with 40% as it frequency followed by 7 - 9 years while the age with least frequency was 16 - 25 years which stood at 22.0%. 28 respondents reported negative effects on their functional domain. 71 of the participants reported negative effects on psychological well-being and 49 of them reported negative effects on social well-being. <strong>Conclusion:</strong> Malocclusion has an overall negative impact on Oral Health Related Quality of Life and its related purviews. It was observed to be highest for the psychological discomfort domain and the lowest in the functional well-being domain. 展开更多

Therefore, upper blepharoplasty is one of the most common procedures performed in plastic surgery. Standardized tools allow for measurement of outcomes through patient satisfaction and surgeon experience. <strong>Objectives: </strong>Our objective was to measure the satisfaction index and scar quality of patients who underwent upper blepharoplasty using the Patient-reported Outcome Measure Questionnaire (PROM-Q) and Patient and Observer Scar Assessment Scale (POSAS). <strong>Methods: </strong>A retrospective review of patients that underwent upper blepharoplasty in our institution was performed. We included those with a preoperative anthropometric analysis, standardized incision markings (developed in our center), same operative technique and a 3-month postoperative evaluation with PROM-Q and POSAS. The sample for this study consists of 67 patients, all of them operated between January 1 2019 and June 30 2019 at the Department of Plastic Surgery, South Central High Specialty Hospital, Pemex, Mexico City, Mexico. <strong>Results: </strong>A total of 67 patients were included, 73% female and 27% male. The most frequent indication for surgery was functional visual symptoms. The index of PROM-Q at 3 months demonstrated an increased satisfaction above 90%, and the evaluation with POSAS reported an almost imperceptible scar. <strong>Conclusion:</strong> Evaluating outcomes with objective tools provides data useful to improve the surgical protocols of patients subjecting to aesthetic procedures. 展开更多
