Using the network analysis method, this study investigates the communication structure of Open Data on the Twitter sphere. It addresses the communication path by mapping influential activities and comparing the contents of tweets about Open Data. In the years 2015 and 2016, the NodeXL software was applied to collect tweets from the Twitter network, containing the term "opendata". The structural patterns of social media communication were analyzed through several network characteristics. The results indicate that the most common activities on the Twitter network are related to the subjects such as new applications and new technologies in Open Data. The study is the first to focus on the structural and informational pattern of Open Data based on social network analysis and content analysis. It will help researchers, activists, and policy-makers to come up with a major realization of the pattern of Open Data through Twitter.

Given the growing attention to nature and health in modern society, this study considered the role of a waterscape facility as a key element in a landscape's influence on users' physiological and psychological responses. The subjects were 28 university students, and the collected data included systolic and diastolic blood pressure, salivary amylase concentration, semantic differential (SD) scales, and profile of mood states (POMS). As compared to a space without any waterscape element (Type G), relaxation in a space with a waterscape element (Type W) was found to significantly reduce of systolic and diastolic blood pressure and salivary amylase concentration. The SD scale and POMS findings showed that Type W evoked active, bright, dynamic, free, vital, interesting, and cheerful images and improved mood states by enhancing vigor while inhibiting depressive feelings. These findings indicate waterscape facilities can improves users' mood states and may enhance their health.

Age-related WMCs frequently appear in older subjects and are known to be associated with cognitive impairment and brain pathologies such as Alzheimer's disease and stroke. However, it is difficult to detect WMC correctly by using only intensity-based clustering scheme because the intensity levels of WC are similar to those of gray matter(GM). In this paper, we aimed to develop a fast and accurate scheme to detect and segment periventricular WMCs by using both k-means clustering method and morphological features.

The study aims to distinguish hemiplegic gait and normal gait using simple wearable device and classification algorithm. Thus, we developed a wearable system equipped three axis accelerometer and three axis gyroscope. The developed wearable system was verified by clinical experiment. In experiment, twenty one normal subjects and twenty one patients undergoing stroke treatment were participated. Based on the measured inertial signal, a random forest algorithm was used to classify hemiplegic gait. Four-fold cross validation was applied to ensure the reliability of the results. To select optimal attributes, we applied the forward search algorithm with 10 times of repetition, then selected five most frequently attributes were chosen as a final attribute. The results of this study showed that 95.2% of accuracy in hemiplegic gait and normal gait classification and 77.4% of accuracy in hemiplegic-side and normal gait classification.

The purpose of this study was to examine the path model of child's sex, temperament, maternal parenting behavior, and child's emotion regulation on child social behaviors. The subjects were 286 elementary school children. Data were gathered through questionnaires reported by mothers and teachers. Path analysis revealed that (1) mother's overprotective or coercive parenting behaviors effected neither child's emotion regulation nor social behaviors (2) child's sex and activity level effected child's aggression both directly and indirectly through child's emotion regulation (3) child's 'activity level' and 'avoidance' temperament effected child's social withdrawal both directly and indirectly through child' emotion regulation. Findings underscore the role of emotion regulation as a mediator in predicting child aggression and social withdrawal.

The objective of this study was to identify how child's gender, temperament, mother's stress and their interactions predict parenting behavior. The subjects were 97 2-year-olds(47boys; 50girls) and their mothers. Data were gathered by questionnaires. Results of a series of hierarchical regression analyses showed combinations of variables that predicted parenting behaviors : (1) mothers reported higher over-protectiveness toward girls and when they were under higher stress. (2) An interaction effect showed that mothers with sons who had higher 'difficult' temperaments reported greater over-protective parenting under greater stress. (3) There were no significant differences in over-protective parenting under low stress, regardless of the level of difficult temperament. (4) Mother's stress was a strong predictor of supportive parenting behaviors.

Purpose: This study was conducted to explore the telemedicine cooperation experience of nurses working in remote areas. Methods: A focus group interviews were used to collect data. All interviews were recorded and transcribed. Content analysis was used to analyze the data. Results: The three main categories and seven sub-categories of telemedicine cooperation experience that emerged are 1) requirement of education on remote support service, 2) consideration of the recipients of medical support services and the characteristics of the area, and 3) difficulties in conducting telemedicine cooperation. Conclusion: As a result of the study, legal protection should be given priority, and it is necessary to select an area where remote cooperation is essential, to discover subjects, and to reduce the burden of work and division of manpower and duties.

Norwegian technology related to preinvestigations, planning, design and construction of large underground caverns is wellknown worldwide. However, so far this technology is only slightly verified through scientiffic reports and documentation. The "Rock cavern stadium" research program is an interdisciplinary program related to the ongoing building and future use of Gjovik Olympic Subsite which is the largest cavern in the world for public purposes with a span of 61 meters and a height of 25 meters. The estimated budget for this program is about USD 4 million which is made possible through grants from The Royal Norwegian Council for Scientific and Industrial Research as well as through contributions from Norwegian and Swedish companies that are participating. The program is carried out in collaboration with The Foundation for Scientific and Industrial Research at the Norwegian Institute of Technology. The Norwegian Geotechnical Institute and The Eastern Norway Research Center. The research program will continue until the end of 1994 to ensure that input comes from a full period of use in this stadium with different activities like exhibitions, conferences, concerts etc being included as verification through full-scale measurements and observations. The research program has five subtasks. Three of these are related to subjects like Energy consumption. HVAC installations. Fire safety design, Engineering geology and Rock mechanics, Environmental aspects. The fourth subtask is concerned with the collection of basic data, results and experience from these three subtasks to provide a basis for national Norwegian guidelines related to this interdisciplinary subject area. The guidelines will first be presented as a manual for planning and engineering purposes. The realization of this research program is a unique opportunity to enhance the expertise that has been acquired from this cavern stadium. By involving research in this extraordinary project from the excavation and building phase to its subsequent use. this will give the participants know-how and expertise which is very much in demand internationally. The coordination of the international activities between the participants as well as preparation of participations and presentations in international conferences and symposium are included in the fifth task of this national research program.
