Pervasive computing and Internet of Things (IoT) have recently received considerable interest to deploy solutions for the future Internet. Smart environments are integrated with Semantic Web to provide context-awareness to the processed information. Self-learning techniques have been adopted within smart solutions for efficient retrieval of data but do not process data with privacy parameters for in-place authorization. To overcome this issue, we present a novel approach of deploying access control as a service mechanism within Semantic Web based smart environment by using eXtensible Access Control Markup Language (XACML). The proposed XACML as a Service (XACMLaaS) approach offers fine-grained access control for protecting information within smart environment. In this paper, we have defined mathematical rules for each components of proposed access control service layer. These rules are for implementation of access control using XACML. The proposed approach allows the adaptation of authorization of information at component level and provides scalable solution for authorization policies and rule enforcement within smart environment.

This study aims to investigate the process of family distress to family crisis in multi-cultural families based on Hill's ABCX model. For this study, the qualitative study with depth interview was conducted with 8 multi-cultural families(e.g. husband, wife, child and elderly parent). The depth interview contents were marriage process, family relation or family interactions, social adaptation process, and social services needs. Results showed the followings: First, multi-cultural families had multiple distressors so that these distressors made multi-cultural families vulnerable to family crisis. Second, Hill's ABCX model explained the process of family distress to family crisis in the multi-cultural families in that they had few resources(both individual resources and family resources) and even worse they had negative cognitions about their own multi-cultural family systems. This situation made them difficult to solve their problems and to cope with their distressors. Third, major distressors in multi-cultural families were founded in this study. These were different cultural gap, communication difficulties, social discrimination to multi-cultural families, and lack of social support networks. Discussion will address suggestions about effective family policies for multi-cultural families in order to make them resilient to family crisis and help to well-adjusted in the korean society.

Purpose: This study was conducted to explore the current usage of high integration mannequin human patient simulators (hereafter HPS) in nursing education. Methods: Thirty-two faculty members in 11 nursing schools participated in this survey. the questionnaire consisted of some multiple-choice questions and open questions to collect data on the experience of faculty members with using HPS as well as quantitative information. Results: The faculty members who used HPS in their classes recognized the need to use simulation in nursing education. They identified the advantages of simulation education as promoting adaptation to the clinical environment(46.9%), promoting self-confidence(28.1%), promoting critical thinking(28.15), and making direct nursing skill practice available(28.1%). However, they considered the obstacles to the use of simulation in nursing education to be insufficient manpower(62.5%), insufficient time(40.6%), and difficulty in preparing a teaching strategy(34.4%). Conclusion: HPS is useful in nursing education, but systematic plans and policies regarding on its operation are needed to confirm its effectiveness. The results of this study generally provide a basic information for use of HPS in nursing education.

The emission of greenhouse gases mainly carbon dioxide and methane is the result of rapid industrialization to meet the demands of ever-growing population. This has resulted in an increase of global temperature which in turn is responsible for severe environmental, social, ecological and economic losses, commonly known as to as 'climate change'. This study attempts to highlight the impacts of climate change mainly focussing on water contamination, sanitation and open defecation in India. The requirement for the instantaneous employment of environment friendly technologies along with improved sanitary system has been discussed. Various other issues which are also linked to climate change that need further management like managing water resources, deterioration in human health, economic losses, modification and successful implementation of policies have been pointed out. Furthermore, stress has been made for the urgent adaptation and rethinking for making strategies along with the involvement of women in order to cop up challenges offered by climate change.

Climate change is considered to be one of the most serious threats and its impact is felt by the most vulnerable world's poorest countries including Bangladesh. In particular, ethnic communities, whose livelihoods depend on the use of natural resources, are likely to bear the brunt of adverse impacts. A case study was conducted in a fragile ecosystem of Lawachara national park of Bangladesh, to know the indigenous knowledge of the ethnic communities, how they adapt with the climate change impact by using indigenous knowledge. They use various IK to protect their crops from climate change impact. Thus, government should design policies which will be helpful to make them more resilience to face climate change impact.

In spite of the increasing popularity of the Ricardian model for the study of the impact of climate change on agriculture, there has been few attempts to examine the role of interregional spillovers in this framework and all of them rely on geographical proximity-based weighting schemes. We remedy to this gap by focusing on the spatial externalities of surface water flow used for irrigation purposes and demonstrate that farmland value, the usual dependent variable used in the Ricardian framework, is a function of the climate variables experienced locally and in the upstream locations. This novel approach is tested empirically on a spatial panel model estimated across the counties of the Southwest USA over 1997-2012. This region is one of the driest in the country, hence its agriculture relies heavily on irrigated surface water. The results highlight how the weather conditions in upstream counties significantly affect downstream agriculture, thus the actual impact of climate change on agriculture and subsequent adaptation policies cannot overlook the streamflow network anymore.

The purpose of this research was to investigate the factors influencing global expansion/scalability of Kenyan Small and Medium Enterprises (SMEs). Factor analysis and multiple/multivariate regression analysis to determine the functional relationship between independent variables (factors) and the dependent variable was used. The independent variables were: innovation & technology, fitness/appropriateness of management, global marketing strategy; and support environment and the dependent variable, global expansion/scalability. Data was collected from a survey of randomly selected firms of 205, drawn from a population of 440 firms from Kenya Manufacturers Directory, with 175 firms responding. The key findings from the research in relation to Kenyan SMEs were that: there is a functional relationship between global market strategy and global expansion; there is a functional relationship between innovation and technology orientation and global expansion, there is no significant functional relationship between supportive environment of firms and their global expansion; and there is no significant functional relationship between fitness/appropriateness of management and global expansion/scalability. The implications for practice is that the ranking of the factors in order of priority supports focusing concern on the orientation of business strategy toward global market strategy, market research geared at obtaining foreign market intelligence, innovation and technology, product adaptation, service orientation, collaborative ventures, and long-range vision as key factors in making Kenyan firms successful in the international market. The implication for policy and practice is that there is need for collaboration between industry and government in pursuing policies for global expansion/scalability and among SMEs and large enterprises particularly in areas of rapid technological change.

One of the most fundamental challenges when designing controllers for dynamic systems is the adjustment of controller parameters. Usually the system model is used to get the initial controller, but eventually the controller parameters must be manually adjusted in the real system to achieve the best performance. To avoid this manual tuning step, data-driven methods such as machine learning were used. Recently, reinforcement learning became one alternative of this problem to be considered as an agent learns policies in large state space with trial-and-error Markov Decision Process (MDP) which is widely used in the field of robotics. However, on initial training step, as an agent tries to explore to the new state space with random action and acts directly on the controller parameters in real systems, MDP can lead the system safety-critical system failures. Therefore, the issue of 'safe exploration' became important. In this paper we meet 'safe exploration' condition with Control Barrier Function (CBF) which converts direct constraints on the state space to the implicit constraint of the control inputs. Given an initial low-performance controller, it automatically optimizes the parameters of the control law while ensuring safety by the CBF so that the agent can learn how to predict and control unknown and often stochastic environments. Simulation results on a quadrotor UAV indicate that the proposed method can safely optimize controller parameters quickly and automatically.
