Innovative Behavior in Nursing Context: A Concept Analysis
Thanuja Ariyasinghe Asurakkody,신소영 한국간호과학회 2018 Asian Nursing Research Vol.12 No.4
Purpose: The aim of this study was to understand the concept of innovative behavior and its theoretical and practical implications for nursing. Methods: Eight-step modification of Wilson's classic concept analysis procedure (1963) by Walker and Avant's (2005) was used to explore the antecedents, attributes, and consequences of innovative behavior in the literature. Electronic searches were conducted in PubMed, Google Scholar, OVID Medline, Science Direct, and ERIC databases using “innovative behavior” or “innovative work behavior”, “innovativeness”, “innovation”, “leadership”, “healthcare”, and “nursing” as keywords, with no limitation on publication date. Results: Organizing the framework based on the method of concept analysis by Walker and Avant , defining attributes to innovative behavior were opportunity exploration, idea generation, idea search, idea communication, promotion of idea, idea championing, application, and overcoming obstacles. Antecedents to innovative behavior are categorized into three groups: organizational characteristics, work environmental characteristics, and individual characteristics. Consequences of innovative behavior included job productivity, lower levels of job burnout, job satisfaction, solving the organizational problems, organizational commitment, organizational efficiency, and effectiveness. Conclusion: Eight dimensions including opportunity exploration, idea generation, idea search, idea communication, idea promotion, championing, application, and overcoming obstacles were analyzed. We suggest promoting innovative behavior through leadership and management in nursing. Future research should focus on developing instruments and conducting empirical studies on innovative behavior in nursing research and practice.

Security plays a vital role and is the key challenge in Mobile Ad-hoc Networks (MANET). Infrastructure-less nature of MANET makes it arduous to envisage the genre of topology. Due to its inexhaustible access, information disseminated by roaming nodes to other nodes is susceptible to many hazardous attacks. Intrusion Detection and Prevention System (IDPS) is undoubtedly a defense structure to address threats in MANET. Many IDPS methods have been developed to ascertain the exceptional behavior in these networks. Key issue in such IDPS is lack of fast self-organized learning engine that facilitates comprehensive situation awareness for optimum decision making. Proposed "Intelligent Behavioral Hybridized Intrusion Detection and Prevention System (IBH_IDPS)" is built with computational intelligence to detect complex multistage attacks making the system robust and reliable. The System comprises of an Intelligent Client Agent and a Smart Server empowered with fuzzy inference rule-based service engine to ensure confidentiality and integrity of network. Distributed Intelligent Client Agents incorporated with centralized Smart Server makes it capable of analyzing and categorizing unethical incidents appropriately through unsupervised learning mechanism. Experimental analysis proves the proposed model is highly attack resistant, reliable and secure on devices and shows promising gains with assured delivery ratio, low end-to-end delay compared to existing approach.

Buddhist meditation for vascular function: a narrative review
Anjalee Thanuja Amarasekera,Dennis Chang 한국한의학연구원 2019 Integrative Medicine Research Vol.8 No.4
Background: High blood pressure represents an important risk factor for diseases related to cardiovascular system and is directly associated with high oxidative stress, inflammation and vascular endothelial dysfunction. Recently, there is promising data available to suggest that meditation-based low-cost and low-risk lifestyle modification strategies may provide beneficial effects on chronic inflammation, oxidative stress and maintenance of blood pressure, both in young and older adults. This review aims to summarize the evidence regarding the effectiveness of Buddhist meditation for vascular endothelial function and blood pressure. Method: A search was conducted using Ovid MEDLINE, Scopus, CINAHL and PsycINFO for articles published from 1990 to 2018. Results: Relevant articles (n = 407) were reviewed and 5 met selection criteria. Several lines of studies have provided compelling data showing that Buddhist meditation approach was effective in improving inflammation and vascular function (endothelial vasodilation and arterial stiffness) in both young and elderly cohorts. Particularly, Buddhist meditation approach has shown to be effective in reducing plasma inflammatory markers, increasing nitric oxide concentration and improving vascular endothelial function and glycemic control, which in turn can be favorable factors for demonstrated positive effects of Buddhist meditation on blood pressure and vascular function. Conclusion: This paper presents brief overview of clinical outcomes of complementary therapeutic approach of Buddhist meditation in vascular function. In future, well-structured systematic reviews are essential to report specificity of Buddhist mindfulness-based approach on vascular function, blood pressure and other cardiovascular risk factors.

Background: Skin metastases from either prostate adenocarcinoma or multiple myeloma rarely occur. We report the case of a 73-year-old man with multiple myeloma who presented with multiple subcutaneous nodules 3 years after his initial diagnosis. Methods: Fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) imaging was suggestive of a concomitant second primary from the prostate. Results: This case highlights not only a rare initial manifestation of prostate cancer, but also the role of 18F-FDG-PET/CT in detecting a clinically unsuspected second malignancy. Conclusion: It potentially corroborates the possible association of both diseases, as has been reported before.

Development of melanoma has been linked to excessive childhood exposure to sunlight. As neonates have a relatively underdeveloped immune system, it is likely that the immune system reacts differently to the exposure, leading to alterations in this development. This study was designed to assess changes in development of the skin immune system following neonatal irradiation. Ultraviolet radiation exposure led to relative depletion of Langerhans cells, however this was not due to migration or cell death, but rather restriction of Langerhans cells populating the epidermis. During this time, there was evidence of cellular damage, however there was no induction of an inflammatory response. It therefore appears that neonatal exposure to ultraviolet radiation leads to a skew towards a tolerogenic immune response, which may lead to a reduced ability to respond to ultraviolet radiation-induced tumours.

Breast cancer (BC) is potentially a traumatic stressor which may be associated with negative outcomes, such as post-traumatic stress disorder (PTSD) or positive changes, such as post-traumatic growth (PTG). This study aims to identify the core issues of BC related PTSD, PTG and psychological distress by interrogating the literature in BC survivors. We have also highlighted issues related to the assessment, diagnosis and clinical management of PTSD and PTG. The authors systematically reviewed studies published from 1985 to 2014 pertaining to PTSD, psychological distress and PTG in BC survivors with particular attention paid to incidence rates and causative factors. Multiple studies intimated that women with BC have evidence of PTSD at the initial stages of diagnosis, whereas PTG develops once patients undergo treatment. Early diagnosis and treatment of PTSD/PTG is paramount from literature review but the previously mentioned relationship between PTSD and PTG in BC patients could not be verified. It is evident from the literature that a small percentage of BC patients experience PTSD, while the majority experience PTG after BC diagnosis and treatment. Future research should include prospective studies focusing on high-risk patients, causative factors and the development of psychological interventions.

Purpose: The aim of this review was to provide the preventive strategies for suicide in Asian countries with the understanding the current status of suicide in Asian countries such as China, Japan, Korea, Sri Lanka and Vietnam. Methodology: We searched a systematic review and online literature from journal articles and other documents about suicide. Results: Sri Lanka has one of the highest suicide rates in the world and Vietnam has the lowest estimated prevalence, followed by China, Korea and Japan have low to medium rates. Some suicide-preventive strategies are used in the Asian countries but they are not popular. There are many training programe about mental health problems for community. Conclusion: Suicide intervention programs in Asia are limited because they are depended the sociocultural situations and economic transitions in the region so we need to coordinate with national suicide prevention organization to prevent the most effectivily suicide.
