  • Recently, the knowledge and use of information production and service in integrated information has been changing from intra-organizational to inter-organizational and even international. In particular, since natural disasters are complexly related, it is increasingly important to use integrated information from related areas in the reduction and prevention of such events. In this study, we suggest strategies for the use of integrated information from natural disasters based on that expanding need. This study analyzes information user surveys, the interrelated information technologies, trends, and case studies to determine user access to the information, the status of the information used, and the supply and distribution of that information. From the survey results, we can draw conclusions about the effectiveness of the strategies of integrated information used in domestic natural disaster information.

  • Purpose: The purpose of this study was to identify the impact of practical communication strategies (PCS) on the reduction of AEs (Adverse Events) in pediatric cardiac ICU (PCICU). Methods: Intra-operative findings and care plans were documented and shared between staff members on a daily basis from the day of operation to the day of general ward transfer. Incidence of AEs was investigated in all patients who were admitted to the PCICU and was compared with incidence of AEs one year after establishment of PCS. Results: The study population consisted of 216 patients in pre-PCS group and 156 patients in post-PCS group. Incidence of readmission decreased from 6.0% (13/216) in pre-PCS group to 0.6% (1/156) in post-PCS group (${\chi}^2=7.23$, p=.010). Incidence of other major complications decreased from 4.2% (9/216) to 0.6% (${\chi}^2=6.66$, p=.012). Minor AEs such as intervention omission, order error, and protocol misunderstanding were reduced from 23.3 cases per 100 patient-days to 7.5 cases per 100 patient-days (${\chi}^2=20.31$, p<.001). Conclusion: Handover protocol is an effective strategy to reduce AEs for critically ill patients after pediatric cardiac surgery. Efforts to develop effective communication strategies should be continued and outcome research about communication strategies for patient safety should be further studied.

  • For high-dimensional classification tasks, such as face recognition, the number of samples is smaller than the dimensionality of the samples. In such cases, a problem encountered in linear discriminant analysis-based methods for dimension reduction is what is known as the small sample size (SSS) problem. Recently, to solve the SSS problem, a way of employing a dissimilarity-based classification(DBC) has been investigated. In DBC, an object is represented based on the dissimilarity measures among representatives extracted from training samples instead of the feature vector itself. In this paper, we propose a new method of optimizing DBCs using multi-level fusion strategies(MFS), in which fusion strategies are employed to represent features as well as to design classifiers. Our experimental results for benchmark face databases demonstrate that the proposed scheme achieves further improved classification accuracies.

  • Iron and nitrogen codoped carbon (Fe-N/C) catalysts have emerged as one of the most promising replacements for state-of-the-art platinum-based electrocatalysts for oxygen reduction reaction (ORR) in polymer electrolyte fuel cells. During the last decade, significant progress has been achieved in Fe-N/C catalysts in terms of ORR activity improvement and active site identification. In this review, we focus on recent efforts towards advancing our understanding of the structure of active sites in Fe-N/C catalysts. We summarize the spectroscopic and electrochemical methods that are used to analyze active site structure in Fe-N/C catalysts, and the relationship between active site structure and ORR activity in these catalysts. We provide an overview of recently reported synthetic strategies that can generate active sites in Fe-N/C catalysts preferentially. We then discuss newly suggested active sites in Fe-N/C catalysts. Finally, we conclude this review with a brief future outlook.

  • The objective of this study is to examine and provide guidelines for regional governments, communities, and the private sector in planning and implementing poverty-reduction activities that are more effective, efficient, and targeted. Besides, this research's specific aims are: 1) increasing the rate of regional economic growth through optimization of potential sources of local income, 2) increasing per-capita income, and 3) reducing poverty, unemployment, and social-economic inequality of the community. The study was conducted in North Morowali District, Central Sulawesi Province, Indonesia, in 2018-2019. The research approach used quantitative and qualitative descriptive analysis. Data sources include sources from the Focus Group Discussion (FGD) and Regional Statistics. The results of this study are based on the Millennium Development Goals (MDG's) indicators that there are four priority scales in poverty reduction, namely, Health and Infrastructure (Priority I), Education (Priority II), Food stability (Priority III), and Population and Employment (Priority IV). Therefore, as a solution to poverty alleviation strategies, the cost approach through regional economic optimization and local income sources and community empowerment factors are essential. Apart from that, the involvement between elements (government, organizations, society, universities, and institutions) is expected to continue as an effort to realize poverty reduction can be optimally overcome.

  • In order for effective heat island reduction policies to be proposed, this research made use of the land usage and land coverage and Temperature of cities, Coordinate axis data within 500 meters of nationwide automatic weather stations (478 points) in order to analyze the correlation of summertime temperatures through multiple regression analysis. This research also developed a model and empirically analyzed the urban heat island reduction effect of factors that affect regional temperatures. Heat islands cause environment deterioration and therefore can harm citizens' health, and also affects the city's metabolism process. Thus in order to restrain regional temperature rises the conclusion was drawn that consideration to increase forest areas on part of land usage planning is needed. Appropriate policy measures to regulate traffic related factors are also needed to restrain regional temperature rises. In order for future heat island reduction this research proposes a way to set up more effective policies and urban sustainability improvement strategies, and is significant in that it makes use of detailed data such as land usage and land coverage, Temperature of cities, Coordinate axis in analyses.

  • In the present study, we aimed to elucidate how muscle strength and activity are affected by movement pattern(bilateral [BLM] & unilateral movement [ULM]) and movement velocity($0^{\circ}$/s, $60^{\circ}$/s, $120^{\circ}$/s) at maximum effort, and to elucidate the relationship between a left/right asymmetry and bilateral deficit. A total of 18 healthy males participated in the study. Each participant performed maximum knee extension bilaterally and unilaterally while the EMG and moment were recorded, and then the relationships between the asymmetry and bilateral deficit were analyzed. The peak moments for the isokinetic motion at $60^{\circ}$/s and $120^{\circ}$/s and overall muscle activities of lower extremity were significantly reduced for the BLM in comparison to the ULM. And though the asymmetry in ULM were maintained during BLM at all velocities, the bilateral deficits at the velocity of $0^{\circ}\acute{y}$/s and $120^{\circ}\acute{y}$/s were significantly correlated with increased asymmetries of muscle strength in ULM. In conclusion, the reduction in the muscle strength exhibited in bilateral knee extension was shown to arise partially from a reduction in muscle activity, and left/right asymmetry was found to be associated with mechanical reduction in bilateral movement. These findings suggest that training aimed at increasing muscle strength must involve methods and strategies intended to reduce left/right asymmetry.

  • Objectives: The rate of metabolic syndrome (MetS) in women diagnosed as they age is one of the main concerns of health cares. Recently new strategies used to prevent progressions of MetS toward the diagnosis of diabetes have focused on plant flavonoids. This study was aimed to investigate the beneficial effects of flavonoids fraction of Mespilus germanica leaves (MGL) on MetS in ovariectomized (OVX) rats. Methods: Twenty-four adult female Wistar rats, weighing 200 to 250 g, were divided into 3 groups: Sham surgery, OVX + Salin, or OVX + Flavonoid. Three weeks after ovariectomy, animals displayed MetS criteria received flavonoid injection (10 mg/kg, intraperitoneally) for 21 days. Then the body weight, body mass index, waist circumference, visceral fat, fasting blood glucose, serum insulin, lipid profiles and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) were measured. Results: Treatment with flavonoids fraction of MGL significantly decreased serum level of insulin (P = 0.011), glucose (P = 0.024), $TNF-{\alpha}$ (P = 0.010), also MetS Z score (P = 0.020) and homeostasis model assessment of insulin resistance (P = 0.007). Lipid profiles and visceral fat showed insignificant reduction. Conclusions: Flavonoids of MGL attenuates some of the MetS components possibly via reduction in $TNF-{\alpha}$ inflammatory cytokine.

  • The purpose of this study is to investigate the effect of retail therapy (RT) values and the role of body consciousness on therapeutic shopping motivations and outcomes. In order to accomplish our research aim, we investigated therapeutic shopping values (i.e., positive mood reinforcement and negative mood reduction) and the moderating effects of body surveillance, body shame, and weight preoccupation. A total of 247 female college students in the United States participated in an online Qualtrics survey, and structural equation modeling (SEM) and multigroup analysis were performed to analyze the data. The findings reveal that therapeutic shopping values (positive mood reinforcement and negative mood reduction) significantly influence therapeutic shopping motivation. Therapeutic shopping motivation, in turn, positively influences therapeutic shopping outcomes. Moreover, weight preoccupation moderates the relationship between negative mood reduction and therapeutic shopping motivation, suggesting that RT should especially be utilized for weight-conscious individuals. The results can be utilized for retailers to develop marketing strategies for consumers who are conscious about their appearance. Academic and managerial implications, along with future research, are suggested.

  • This study aims to investigate effects of scaffolding on writing apprehension and media literacy in engineering freshmen's synchronous online writing course, and the relationships between the two variables. 'Scaffolding' is in-time support provided by a teacher/tutor or competent peer that enables students to meaningfully gain skills at problem solving process. Also, it is one of the most frequently mentioned concepts in education as well as one of the more necessary teaching strategies in an online writing course. In this study, provided treatments for the experiment were supportive scaffolding for domain-specific knowledge and reflective scaffolding for meta-cognitive knowledge. Participants were 102 engineering undergraduate students, who were assigned to two experimental groups by scaffolding types. A process-based writing course in online learning environment was conducted for 8 weeks. The writing tasks were given according to writing process. The findings were that, firstly, there were statistically significant writing apprehension's reduction and self-expression's improvement through the scaffolding provided in writing class. Secondly, writing apprehension's reduction and self-expression's improvement were significant in supportive scaffolding group. Thirdly, media literacy predicted writing apprehension. The practical implications of these findings are discussed herein, with particular attention on ways for writing apprehension's reduction as well as media literacy's enhancement.
