Parkinson’s disease (PD) is a progressive neurodegenerative disorder of the basal ganglia. Most PD patients suffer from somatomotor and oculomotor disorders. The oculomotor system facilitates obtaining accurate information from the visual world. If a target moves slowly in the fronto-parallel plane, tracking eye movements occur that consist primarily of smooth-pursuit interspersed with corrective saccades. Efficient smooth-pursuit requires appropriate target selection and predictive compensation for inherent processing delays. Although pursuit impairment, e.g. as latency prolongation or low gain (eye velocity/target velocity), is well known in PD, normal aging alone results in such changes. In this article, we first briefly review some basic features of smooth-pursuit, then review recent results showing the specific nature of impaired pursuit in PD using a cue-dependent memory-based smooth-pursuit task. This task was initially used for monkeys to separate two major components of prediction (image-motion direction memory and movement preparation), and neural correlates were examined in major pursuit pathways. Most PD patients possessed normal cue-information memory but extra-retinal mechanisms for pursuit preparation and execution were dysfunctional. A minority of PD patients had abnormal cue-information memory or difficulty in understanding the task. Some PD patients with normal cue-information memory changed strategy to initiate smooth tracking. Strategy changes were also observed to compensate for impaired pursuit during whole body rotation while the target moved with the head. We discuss PD pathophysiology by comparing eye movement task results with neuropsychological and motor symptom evaluations of individual patients and further with monkey results, and suggest possible neural circuits for these functions/dysfunctions. © 2017, Springer-Verlag Berlin Heidelberg.

We design a collaborative e-learning system for stable operation in an unstable environment of developing countries. The proposed system is used for providing a collaborative learning among local schools of rural area in Nepal. The stable operation of the system is realized by the redundant robustness in three different levels: network arrangement, energy management, replicative database. In this paper, we present an overall design of the system, its use case. Then, methods adopted for achieving the redundancy in each level are described. © 2016 IEEE.

Accurate knowledge of the extent of biogenic opal preservation in marine sediment cores is important for paleoceanographic reconstructions. The alkaline leaching method is widely employed for %biogenic opal analysis due to its ease and speed. In this study, a revised method for measuring %biogenic opal in sediment from arctic coring expedition samples was suggested. The studied middle Eocene sediments from the central Arctic Ocean presented a problem in insufficiently leaching biogenic opal with a Na2CO3 solution. Based on XRD analysis, it was suggested that such an alkaline resistance results from slight diagenesis of biogenic opal. In order to solve this problem, an alkaline leaching method utilizing a 2 M NaOH solution was suggested for the accurate measurement of %biogenic opal in the Eocene sediments from the central Arctic. Furthermore, dissolution rates from lithogenic matter by NaOH solution were measured in order to correct the %biogenic opal values. © 2014 The Oceanographic Society of Japan and Springer Japan.

High resolution paleoceanography of the Pliocene-Pleistocene is important in understanding climate forcing mechanisms and associated environmental changes during this major transition from global warmth to the Ice Ages. This is particularly true in high latitude marginal seas such as the Bering Sea. The Bering Sea has been very sensitive to changes in global climate during interglacial and glacial, or Milankovitch, time scales. This is due to significant changes in water circulation, land-ocean interaction, and sea-ice formation. With the aim to reveal the climate and oceanographic history of the Bering Sea over the past 5. My, IODP Expedition 323 cored a total of 5741. m of sediment (97.4% recovery) at seven sites in 2009 on D/V JOIDES Resolution covering three regions: the Umnak Plateau, the Bowers Ridge, and the Bering Slope. The water depths of the drill sites range from 818. m to 3174. m, allowing for the characterization of past vertical water mass distribution including changes in the oxygen minimum zone. The four deepest holes range from 600. m to 745. m below the seafloor, and resulted in the recovery of long sediment sequences ranging from 1.9. My to 5. My in age. Following the expedition, two sampling parties at Kochi Core Center (for acquisition of ca. 58,000 subsamples) and two scientific meetings were conducted in order to proceed with the analyses of sediment core samples and discussions. Here, pertinent results, primarily from IODP Expedition 323, are consolidated as a single special volume of Deep-Sea Research Part II Topical Studies in Oceanography. © 2016.

Introduction: Post-traumatic stress disorder (PTSD) is a common condition among Japanese firefighters. The purpose of this study was to clarify the relationship of PTSD scores to job stress, social support, and depressive stress among Japanese firefighters. Methods: A total of 1,667 Japanese firefighters working for the local government completed a questionnaire that was used to gather information pertaining to age, gender, job type, job class, marital status, and smoking and drinking habits. Questionnaires from the Center for Epidemiologic Studies Depression Scale (CES-D), the Japanese version of the U.S. National Institute for Occupational Safety and Health (NIOSH) Generic Job Stress Questionnaire, and the IES-R were also used. Results: After adjustment for age and gender, subjects in the PTSD-positive group had significantly higher scores for inter-group conflict, role ambiguity, and CES-D, as well as significantly lower scores for social support from their supervisors compared to those in the PTSD-negative group. Conclusions: High inter-group conflict and role ambiguity, as well as low social support from supervisors and the presence of depressive symptoms, may influence the development of PTSD among Japanese firefighters. © Saijo 2012 World Association for Disaster and Emergency Medicine.

This study aimed to explore attitudes towards cervical cancer screening among Japanese university students who had never had a Pap smear. Four focus-group discussions, each with 15 female university students, took place in November and December 2009. Discussions were recorded and transcripts were analyzed to extract attitudes of young women towards cervical cancer screening. The four themes that emerged were: i) a low sense of reality about cervical cancer; ii) a lack of knowledge about both cervical cancer and Pap smears; iii) a lack of motivation to get screened, and iv) a reluctance to visit the gynecologist. Participants who were interested in undergoing screening for cervical cancer cited the influence of conversations with friends and family, a diagnosis of cancer within their family, and relevant information from the media. The results indicate the importance of getting young women more interested in cervical cancer screening and overcoming their tendency to avoid visiting a gynecologist.

Late Pliocene to early Pleistocene paleoproductivity changes in the Bering Sea were reconstructed using geochemical concentrations and mass accumulation rates (MARs) of CaCO3, biogenic opal, and total organic carbon (TOC), and sedimentary nitrogen isotope ratios (δ15N) at IODP Expedition 323 Hole U1343E, drilled in the northern slope area (1956m deep) of the Bering Sea. CaCO3 concentration is generally low, but prominent CaCO3 peaks occur intermittently due to subseafloor authigenic carbonate formation rather than biogenic accumulation, regardless of glacial-interglacial variations. Biogenic opal concentrations reflect orbital-scale glacial-interglacial variations. However, TOC concentration did not show clear glacial-interglacial variation, probably due to poor preservation. The sedimentary δ15N values vary synchronously with biogenic opal concentration on orbital timescales. The co-varying pattern of opal productivity and δ15N values at Hole U1343E is a result of nutrient utilization controlled by diatom productivity in the Bering slope area where Fe is not a limiting factor. Biogenic opal and TOC MARs showed a temporal shift at around 1.9Ma from a high productivity period under nutrient-enriched conditions to a low productivity period under relatively nutrient-depleted conditions. High diatom productivity with low δ15N values before 1.9Ma is associated with abundant nutrient supply by upwelling in relation to strong surface current system. This productivity decrease at about 1.9Ma was also found in the southern Bering Sea (Site U1341) and may be related to global opal reorganization. © 2015 Elsevier Ltd.

Two experiments were performed in order to examine an interaction of room acoustics and the interior design of the room. The room used in these experiments was "interior-designed room." In Experiment 1 two types of BGM were prepared and a change of room evaluation was investigated in terms of types of BGM: Used BGM as a room acoustics were "relaxation music" and "no-relaxation music." Participants were asked to rate the degree of harmony between music and room interior design. Result were that 1) a relaxation music was judged more appropriate for room interior design than no-relaxation music; 2) the room interior design was estimated more calm when BGM was relaxation music. In Experiment 2 the change in the impression and the likes and dislikes concerning this room were examined by using two types of lightening: relaxation lighting and ordinary lighting. 60 participants were asked to rate the impression and the likes and dislikes concerning this room. The results were that 1) the change in the impression from the lighting didn't change the atmosphere formed by the interior design, and 2) the good impression of the room improved when the calm lighting was used. This study showed that both BGM and lighting had an influence on the atmosphere of the indoor room. It can be said that BGM as a room acoustics and lighting can play an additional role in a highly-designed indoor room.

This paper addresses some of the issues of definition among monolithic management, web enabled campus administration and report management systems. It is difficult to depict the comparative analysis of web enabled management because of the evolutions of diverse models of implementation, especially new commercial tools that are available in the academic communities and Information Technology (IT) industries. We will not analyze the prevailing commercial tools. The paper highlighted the importance of usage of web enabled management system that enhanced the entire performance of the administration on the basis of Campus-SIA (Campus Student Information Application) that we implemented during our research. Furthermore, the purpose of this paper is to discuss the potential of web enabled management system that we hope to enable the entire campus management beyond its monolithic management system. This approach of using web enabled management system in support of all-in-one portal approach is presented, and it is argued that monolithic with modular management systems via single access of point supports a constructivist approach of campus management and further encourage the collaborative management style, thus we introduce Campus-SIA that emphasizes all-in-one management activities of campus staff. This paper further demonstrated that campus staff administrative processes are supported by providing configuration tools for each successive year in order to automate and minimize daily administrative tasks. Performance of administration has been achieved through the introduction of layered architecture of reporting systems.

Security is a major issue in cloud computing technology. In order to increase the service level of trust among the cloud service providers and its users, understanding of Cloud Computing Architecture requires an understanding of Cloud's principal characteristics such as how the services are delivered and deployed, how they are consumed and ultimately how they need to be partitioned, managed and safeguarded. Due to the uncertain and undefined security definitions in Cloud Computing Technology, business communities often raise concerns in this domain. Until date, most of the big giants of Cloud Computing Technology such as Google, Amazon, IBM and Yahoo have not proposed a trustable and reliable solution for storage of client's confidential data. In this proposal, we propose a different solution and security policy in order to promote a common level of understanding between the users, business communities and necessary security requirements. We are confident in achieving a high level of trust from the user of our proposed security model in which we facilitate the users to retain their data in their own environment so that they will have full control of their data while using the services from the service provider. Furthermore, we have developed an interface in which all kinds of applications can be executed and which is termed as the Universal Browser.
