We develop a new auto-guiding system for the Camera for QUasars in the EArly uNiverse (CQUEAN). CQUEAN is an optical CCD camera system attached to the 2.1-m Otto-Struve Telescope (OST) at McDonald Observatory, USA. The new auto-guiding system differs from the original one in the following: instead of the cassegrain focus of the OST, it is attached to the finder scope; it has its own filter system for observation of bright targets; and it is controlled with the CQUEAN Auto-guiding Package, a newly developed auto-guiding program. Finder scope commands a very wide field of view at the expense of poorer light gathering power than that of the OST. Based on the star count data and the limiting magnitude of the system, we estimate there are more than 5.9 observable stars with a single FOV using the new auto-guiding CCD camera. An adapter is made to attach the system to the finder scope. The new auto-guiding system successfully guided the OST to obtain science data with CQUEAN during the test run in 2014 February. The FWHM and ellipticity distributions of stellar profiles on CQUEAN, images guided with the new auto-guiding system, indicate similar guiding capabilities with the original auto-guiding system but with slightly poorer guiding performance at longer exposures, as indicated by the position angle distribution. We conclude that the new auto-guiding system has overall similar guiding performance to the original system. The new auto-guiding system will be used for the second generation CQUEAN, but it can be used for other cassegrain instruments of the OST.

With a rapidly aging population, the proportion of elderly households with low income has been increasing. Despite the poor housing environment, it is not easy to improve their housing environment due to the high cost of modification. However, as many elderly want to keep living in their current houses, it is urgent to improve their housing environment. The purpose of this study was to develop the guidelines on home modification for low-income elderly. This study set the scope of home modification categories through literature analysis in advance to develop the guidelines. Based on the literature analysis and small group workshops, the primary and secondary guidelines were derived and a total of 169 final guidelines were produced based on the scope of home modification categories. Those guidelines were composed of the categories by space, divided into mandatory and recommended by details. Those guidelines proposed in this study were classified and composed under the objective standards, so that they were systemic and objective based on the verification of experts. They are considered to get closer to the user's demand on the basis of the demand of low income elderly for home modification and the improvement categories under the system to support home modification for low income elderly at home and abroad. In addition, as the standards to apply each guideline, separated into mandatory and recommended, was suggested, those guidelines may help expand the scope of improvement under the economic conditions for home modification.

This paper presents an efficient multicast method based on a locality in mobile IPv6 networks. We exploit the repetitive movement pattern of mobile node to reduce the total number of experience of graft and join procedure. We defined the locality scope by a movement pattern. While the network is included in the locality scope, the network should maintain a multicast tree even when the mobile node moves to the other network. In this way, the mobile host can receive a multicast service without a delay when it moves to the network in the locality scope later. We compare our scheme with existing schemes under the total signaling cost and the service delay time by using a discrete analytical model for cost analysis. Analytical results demonstrated that the total signaling cost and service delay time was significantly reduced through our proposed scheme.

This study aimed to compare and analyze the content structures of the information literacy curriculum 'Library and Information Life' and domestic and international digital literacy curricula to discuss the scope of digital literacy integration based on information literacy. Common areas and learning elements were extracted from domestic and international digital literacy curricula and mapped against the 'Library and Information Life' curriculum. Results showed that while the middle school curriculum aligned in information literacy, creation and sharing, and digital ethics, 'Library and Information Life' did not mention ICT utilization, communication, and collaboration competencies. The high school 'Media and Information Life' curriculum also addressed ICT utilization, communication, and collaboration competencies in a limited manner. This study is significant in proposing a concrete discussion on the scope of digital literacy integration based on information literacy. The findings can serve as foundational data for determining the scope of digital literacy application when revising the 'Library and Information Life' curriculum in the future.

The purpose of this study is to confirm whether the fit between the task and the information characteristics makes any effects on the user satisfaction. The task is defined as two sub-constructs representing the degree of exception and analyzability. The information characteristics is divided into the degree of aggregation, scope and timeliness of information. User satisfaction was used as a surrogate measure of the performance of information systems. The computer self-efficacy was used to control any confounding effects. Field research method using questionnaires was employed to empirically investigate the relationship among the variables. Findings of the study are summarized as follows: the fit between the task and the aggregation of information and between the task and the scope of information turned out to have significant effects on information system performance. The implication of such results is that under highly exceptional or less analyzable task environment, less-aggregated or broad information is more appropriate.

As competition in manufacturing enterprise is contested, the scope of safely production planning, manufacturing enterprise should ensure, has been reduced. The more upstream of SCM, the more reduction of scope of production planning. As a result, order fluctuation is more sharply contested. Through improving the logistics network, it is best way that the end user's demand information is conveyed to upstream of SCM, but it is difficult in fact. In this paper, it mention the way of robustic adjustment, in the suppliers' point of view, the end user's demand information is dammed up, as they postpone responding the customer's order as a possible. And it will show the result of appling the way, as a case study.

This study was conducted to develop standards for evaluating what extent the physical environments of housing which can cope with the needs of the aging society. To set up the evaluation items of housing for the elderly, the evaluation items were formulated after analyzing the items or indices presented by the previous studies. This study was proceeded with in such an order as setting up the scope of evaluation, setting up the areas of evaluation, and setting up the items of evaluation. The scope of evaluation was limited to the indoor spaces of housing as it was thought that the elderly spend much more time at indoors, considering their physical characteristics. The areas of evaluation were composed of seven areas; general matters of housing(14 items), bedroom(35 items), living room(24 items), kitchen(29 items), bathroom(45 items), toilet(40 items), and staircase(15 items). The items of each area included those relevant to general matters, heating and ventilation, light source, openings, and related equipment. Therefore, the items of the evaluation areas were 202 in total.

This study was predicted the diffusion of the conservative contaminant using a two-dimensional hydraulic model. The research area is upper basin of Jakwang river where the possibility where the pollutant of vast quantity will flow is high. Using SMS model, we calculated two-dimensional stream flow. And using this result, predicted the conduct of the conservative contaminant by pollutant transfer diffusion calculation. And also we predicted flow and contaminant diffusion in the near estuary by constructed guide bank. As a result of study, pollutant effect scope of the conservative contaminant was predicted with the fact that will broaden because of interception by guide bank. As discharge was increased from the Jakwang river, The diffusion of the pollutant is accelerated, also the effect scope increases.
