Hubungan Interaksi Sosial Dengan Kualitas Hidup Lansia Di Bplu Senja Cerah Provinsi Sulawesi Utara

: Globally, the population of the elderly continue to rise. The increase of the number of elderly people is accompanied with a rise in health problems that are associated with the elderly. The degenerative process on the elderly causes the degeneration of the physical, psychological, and social conditions. One of the impacts of social change that is experienced by the elderly is the self-withdrawal of the elderly from their living environment. The purpose of the research is to analyze the association between social interaction and the quality of life of the elderly at BPLU Senja Cerah in North Sulawesi Province. The method of research is analytical descriptive with a cross-sectional design. The sample-taking technique in the research is purposive sampling with 32 samples. The collecting of data is done using a questionnaire. The processing of data uses the software computer with chi-square with the level of confidence interval of 95% (α=0,05). The results of the research shows the number of respondents with a good level of social interaction is 21 respondents, with 4 (12,5%) respondents having a sufficient quality of life, and 16 (50,0%) respondents with a high quality of life, while there are 12 respondents with a sufficient level of social interaction, where 9 (28,1%) respondents show a sufficient quality of life and 3 (9,4%) of respondents with a high quality of life and there is a p value of 0,004 < 0,05. This conclusion shows that there is a relationship between social interaction and the quality of life in the elderly

Continuity and variability in prehistoric fishing practices by Homo sapiens in Island Southeast Asia: new ichthyofaunal data from Asitau Kuru, Timor-Leste

Human adaptations to marine resources were critical in the successful colonization of Island Southeast Asia (ISEA) and the Pacific since the Late Pleistocene. Fishing the dense biomass of ichthyofauna present in this maritime region required the cognitive capability to conceptualize fish ecology and develop methods and technologies to exploit these challenging underwater environments. This likely gave our species an edge over other hominin species in depauperate island landscapes. This paper reviews the limited number of archaeological sites in ISEA where fish bone assemblages and fishing gears have been recovered, incorporating new archaeological data from the site of Asitau Kuru (Jerimalai), Timor-Leste. Our findings indicate continuity in fishing behavior over several millennia with a near-shore exploitation of local marine habitats including trolling, line fishing and spearing. These data indicate the ecological plasticity of our species and the enduring fishing traditions passed on to generations through learned behavior

Very Low Temperature Tunnelling Spectroscopy in the heavy fermion superconductor PrOs4_4Sb12_{12}

We present scanning tunnelling spectroscopy measurements on the heavy fermion superconductor PrOs$_4$Sb$_{12}$. Our results show that the superconducting gap opens over a large part of the Fermi surface. The deviations from isotropic BCS s-wave behavior are discussed in terms of a finite distribution of values of the superconducting gap.Comment: 4 pages, 4 figure

Revisiting the link between business strategy and performance: Evidence from hotels

This paper aims to investigate the competitive success factors for hotel companies and examine the link between business strategy and performance. Using a structured questionnaire, the researchers collected data from hotel managers in Spain. Study results suggest that a firm’s assets and strategies have a greater influence on performance than industry forces do. This lack of direct influence by industry forces is due to the sector’s specific characteristics, which cannot be overlooked during analysis. Based on these research findings, theoretical and managerial implications and future research are presented

Independent determination of the two gaps by directional point-contact spectroscopy in MgB_2 single crystals

Directional point-contact spectroscopy measurements were performed for the first time in state-of-the-art MgB_2 single crystals. The selective suppression of the superconductivity in the "pi" band by means of a suitable magnetic field allowed separating the partial contribution of each band to the total point-contact conductance. By fitting the partial conductance curves sigma_sigma(V) and sigma_pi(V), we got an independent determination of the two gaps, Delta_sigma and Delta_pi, with a strong reduction of the experimental uncertainty. Their temperature dependence was found to agree well with the predictions of the two-band models for MgB_2.Comment: 6 pages, 4 eps figures.

Victimization and peer and parents attachment: The mediating effect of regulatory emotional self-efficacy

Studies of the Spanish adolescent population has concluded that victimization is related to lack of emotional regulation and impulse control. Therefore, if a victim is unable to recognize, understand and regulate their emotions, this can result in rejection by their peers. A cross-sectional study was conducted to examine regulatory emotional self-efficacy as a possible mediator in the association between peer and parents attachment and victimization. Adolescents (n = 563) completed Regulatory Emotional Self-Efficacy, Inventory of Parents and Peer Attachment and Kid at School questionnaires. Structural equation models (SEMs) were used to predict a latent variable of victimization with parents and peer attachment, emphasizing the mediating role of regulatory emotional self-efficacy, as comprised by a positive and a negative aspect. Results showed that peer attachment had an indirect negative effect, through perceived self-efficacy, in managing a positive effect in victimization, while father attachment had an indirect negative affect, through perceived self-efficacy, in managing a negative affect in victimization, and Mother attachment had no statistically significant indirect effect in victimization. This study suggests that the roles of parents and peers, and also between mothers and fathers, are different in relation to the perception of victimization of adolescents. Findings provide relevant information regarding implications for prevention and intervention in victimization

Semantic Modelling Approach for Safety-Related Traffic Information Using DATEX II

The significance of Linked Open Data datasets for traffic information extends beyond just including open traffic data. It incorporates links to other relevant thematic datasets available on the web. This enables federated queries across different data platforms from various countries and sectors, such as transport, geospatial, environmental, weather, and more. Businesses, researchers, national operators, administrators, and citizens at large can benefit from having dynamic traffic open data connected to heterogeneous datasets across Member States. This paper focuses on the development of a semantic model that enhances the basic service to access open traffic data through a LOD-enhanced Traffic Information System in alignment with the ITS Directive (2010/40/EU). The objective is not limited to just viewing or downloading data but also to improve the extraction of meaningful information and enable other types of services that are only achievable through LOD. By structuring the information using the RDF format meant for machines and employing SPARQL for querying, LOD allows for comprehensive and unified access to all datasets. Considering that the European standard DATEX II is widely used in many priority areas and services mentioned in the ITS Directive, LOD DATEX II was developed as a complementary approach to DATEX II XML. This facilitates the accessibility and comprehensibility of European traffic data and services. As part of this development, an ontological model called dtx_srti, based on the DATEX II Ontology, was created to support these efforts

Properties of composite laminates based on basalt fibers with epoxidized vegetable oils

This paper deals with the development of polymeric materials derived from epoxidized vegetable oils which have been used in the manufacture of laminated composite materials with basalt fabrics. Epoxidized linseed oil (ELO) and epoxidized soybean oil (ESBO) were used as biobased matrices. The basalt fabrics were modified with amino-silane and glycidyl-silane to increase fiber-matrix interactions. The curing behaviour of both resins was evaluated by differential scanning calorimetry (DSC) and oscillatory rheometry (OR). The evaluation of mechanical properties was made by tensile, flexural and Charpy tests. The extent of the fiber-matrix interactions among interface was evaluated by scanning electron microscopy (SEM). The obtained results revealed that surface modification of basalt fibers with glycidyl-silane clearly improves the mechanical properties of the composites. The use of the ELO resin as matrix for composite laminates improved substantially the mechanical performance compared to composites made with ESBO. (C) 2015 Elsevier Ltd.

New environmentally friendly composite laminates with epoxidized linseed oil (ELO) and slate fiber fabrics

This work focuses on the development of new composite laminates based on the use of epoxidized linseed oil (ELO) as matrix and reinforcement fabrics from slate fibers with different silane treatments. The curing behavior of the ELO resin is followed by differential scanning calorimetry (DSC) and the gelation is studied by oscillatory rheometry and gel-time. Composite laminates of ELO matrix and slate fabrics are manufactured by Rein Transfer Molding (RTM) and the mechanical properties of the composite laminates are tested in tensile, flexural and impact conditions. The effects of different silane coupling agents on fiber-matrix interface phenomena are studied by scanning electron microscopy (SEM). As in other siliceous fibers, silane treatment leads to improved mechanical performance but glycidyl silane treatment produces the optimum results as the interactions between silanized slate fiber and epoxidized linseed oil are remarkably improved as observed by scanning electron microscopy (SEM).
