Recent science technology research network moves to establish logical private network among specific research groups such as high energy physics and climate, requiring to implement private network by group for each purpose. Up to now, national research networks such as KREONET service high capacity logical private networks. Therefore standardized configuration and management scheme is essential for the deployment of logical private network. In this study, we propose the core service element and protocols for the logical networks over Layer 2 networks. We also propose system architecture that make monitoring and management easier. After that we design and implement monitoring map for logical network based on scheme. For this purpose, we also propose the description system for logical research network to provide data such as operation information, formation information, performance information and failure information of network infrastructure resource.

Recommender Systems have gained immense popularity due to their capability of dealing with a massive amount of information in various domains. They are considered information filtering systems that make predictions or recommendations to users based on their interests and preferences. The more recent technology, Linked Open Data (LOD), has been introduced, and a vast amount of Resource Description Framework data have been published in freely accessible datasets. These datasets are connected to form the so-called LOD cloud. The need for semantic data representation has been identified as one of the next challenges in Recommender Systems. In a LOD-enabled recommendation framework where domain awareness plays a key role, the semantic information provided in the LOD can be exploited. However, dealing with a big chunk of the data from the LOD cloud and its integration with any domain datasets remains a challenge due to various issues, such as resource constraints and broken links. This paper presents the challenges of interconnecting and extracting the DBpedia data with the MovieLens 1 Million dataset. This study demonstrates how LOD can be a vital yet rich source of content knowledge that helps recommender systems address the issues of data sparsity and insufficient content analysis. Based on the challenges, we proposed a few alternatives and solutions to some of the challenges.

Objectives: The mandible and other parts of the maxillofacial region suffer significant morbid injuries following road traffic accidents. Our study gives epidemiological description of mandibular fractures in Ghana and also evaluates the relevance of closed reduction and indirect fixation for managing mandibular fractures in low-resource health facilities in low-income countries like Ghana. Patients and Methods: This is a retrospective study involving 268 patients who reported to the Department of Oral and Maxillofacial Surgery of the Sunyani Regional Hospital with mandibular fractures from January 2010 to December 2019. Patient medical records were assessed for information on age, sex, fracture etiology, anatomic location of fracture, time of day of road traffic accident, and other associated injuries. Results: A total of 268 patients were included in this study (males, 216 [80.6%]; females, 52 [19.4%]). Motor vehicular accident (MVA) was the leading cause of mandibular fractures (202 injuries, 75.4%). Other etiologies included assault (39, 14.6%), gunshot (13, 4.9%), falls (12, 4.5%), and industrial accidents (2, 0.7%). Of the 161 male cases caused by MVA, 121 (75.2%) occurred at night and in the evening while the remaining 40 (24.8%) occurred in the morning and afternoon. Among all managed 222 patients, 212 (79.1%) were treated with closed reduction and indirect fixation technique while 10 (3.7%) were treated with open reduction and direct fixation. Conclusion: Closed reduction with indirect fixation could successfully be used to manage mandibular fractures in low resourced health facilities, especially in low-income countries. The poor lightening system on roads in Ghana is a major contributory factor to motor vehicular accidents.

Eleotris oxycephala was described in detail as the first reliable record from Korea based on a single specimen (62.1 mm SL) collected from the lower reach of Jwagwang stream near Busan, Korea. The specimen is easily distinguished from three congeners occurring in the northern West Pacific by having separation between two rows of sensory papillae on opercle and the fourth row of the papillae on cheek not extending beyond the 11th longitudinal sensory-papillae.

In order to overcome the problems of current approaches to metadata interoperability based on element mapping, this research proposed Master Element Framework that is an alternative approach to metadata interoperability. It is an approach to integrate metadata elements that have the same value, instead of direct mapping between similar elements. Master Element Framework is constructed to semantically integrate metadata elements in a hierarchical order and to interconnect between heterogeneous metadata standards. This approach is expected to be an alternative approach to metadata interoperability.

Purpose : This study was conducted to provide for a basic resource, which can be used to set up a efficient management system in Cardiac Surgery Intensive Care Units(CSICU). Method: 1) Questionnaires were administered and observation methods were used, to examine the nursing activities performed in the CSICU after having reviewed related literatures and a review by the experts. Thus, the nursing activities were designating 254 activities and classified into 28 categories. 2)The 22 nurses in the 2 CSICUs filled out questionnaires about nursing activities from 12 April, 2002 to 17 April, 2002. The frequency of the nursing activities in the 28 categories counted and new nursing activities added by directly observing 12 nurses by two trained research staffs for 4 day. 3)In terms of validity, the 264 nursing activities were analysed by the 25 experts. As a result, 231 nursing activities were found valid and remained as appropriate nursing activities to be used for the careful analysis of the nursing activities in CSICUs. Result: The 22 categories are as below: assessment, monitoring, respiration management, nutrition management, elimination/drainage management, mobility management, sanitation management, safety management, temperature management, specimens collection, preparation and assistance of treatment, skin/wound management, infection management, medication management, education/support, dying patient care, recording/keeping, supplies management, environment management, communications, evaluations, professional development Conclusion : The manifest job description of the staff nurse will contribute to improving the efficiency of the nursing activities and to reducing the role conflicts among the medical staffs.

Due to the limitation of the bandwidth resource and capture resolution of depth cameras, low resolution depth maps should be up-sampled to high resolution so that they can correspond to their texture images. In this paper, a novel depth map up-sampling algorithm is proposed by exploiting the fractal internal self-referential feature. Fractal parameters which are extracted from a depth map, describe the internal self-referential feature of the depth map, do not introduce inherent scale and just retain the relational information of the depth map, i.e., fractal transforms provide a resolution-independent description for depth maps and could up-sample depth maps to an arbitrary high resolution. Then, an enhancement method is also proposed to further improve the performance of the up-sampled depth map. The experimental results demonstrate that better quality of synthesized views is achieved both on objective and subjective performance. Most important of all, arbitrary resolution depth maps can be obtained with the aid of the proposed scheme.

Objectives: The nurse visiting health service named Customized Visiting Health Care Program(CVHCP) requires the service innovations incorporating community support into a local service network. The purpose of this study was to assess the community network in CVHCP and inform improvement in this network. Methods: We used Social Network Analysis(SNA) in one CVHCP at H city. Network links were generated by self-administered questionnaires by the 14 community resource centers who quantified their links to all other 25 agents on the list. Links were analyzed by a dichotomous scale for any experience of collaboration and a scored scale of 0 to 3 for level of collaboration using UCINET v6. Results: A list of 14 agents was generated, and local network was dominated by the Public Health Center and a local welfare center named Unlimited Care Center(UCC). According to centrality score, UCC was the most prominent agent, and Public Health Center was the most influential agent, being a link in the pathway flow between other agents for 9.5% of contribution. CVHCP scored lower rank of prominent with 30.8% of other agents reported referring to it. Conclusions: Social network analysis provides a useful network description for informing and evaluation service network improvement in maximizing its service for the CVHCP.

The semantic web was proposed as the next generation web technology. In the environment of the semantic web, resources as well defined and related with each other semantically, the RDF supports this basic mechanism. To establish and develop the semantic web. the basic technologies related to RDF data must be pre-established. In this research, we develop methods for storing and querying RDF data using an XML database system. As using XML database, XML data and RDF data can be integrated and efficiently managed. We construct and evaluate a system applying the proposed method to store and search data, we compared the query processing performance on our system with that of an existing system. The experiment result show that our system processes queries more efficiently.
