Objectives: The purpose of the study was to investigate the relation between learning strategy and academic achievement in the dental hygiene students. Methods: A self-reported questionnaire was completed by 207 dental hygiene students in Gyeongnam from April 1 to 30, 2014. The questionnaire consisted fo 51 questions of learning strategy and 1 question of academic achievement. The data were analyzed using SPSS 17.0 program for descriptive analyses, t-test, Pearson correlation and multiple regressing analysis. Results: The organized strategy and learning time management had a significantly positive influence on high scores in the junior and senior students. Learning strategie(r=0.419) and cognitive strategies(r=0.343), metacognitive strategies(r=0.239), resource management strategies(r=0.415) had significantly positive correlation to academic achievement. Cognitive strategy of learning strategies(p<0.05) and resource management strategies(p<0.001) had a positive effect on higher academic achievement. Conclusions: The learning strategies will provide the dental hygiene students with active participations.

In korea, since November 1982 these two small group actvity convension (QC circle convension and Factory Saemaul activity small group convension) has been united, many problem have been disclosed that are against the basic principle more or less. Worker's small group activity is essentially, a trouble shooting oriented voluntary small group within their working place to improve the surroundings creatively. In practice. however, many group are so typical and so impetuous of the material effect that it is worried to be inclined to outform rather than contents. Effective small group activities are presumed to be successful only with labor management cooperation on the basis of human-orient management philosophy. The small group activities are also prevalent in service sector. More derivative methods have been developed and more members are willingly participating in training programs. The small group which is basically a horizontal organization unit, promptes communication within the whole organization. In consideration of the social circumstances and traditions, the flexible model of the small group activities suitable to the corporate environment, will contribute industrial development.

Sustainable meal management at home will be affected by the lifestyle of the housewife. This study examined the lifestyle of middle aged women and identified their practice levels of sustainable meal management at home. A total of 438 women, aged 35 to 59, managing the family's dietary life at home and living in Seoul, Gyeonggi Province, Daejeon, and Chonnan area participated in the survey. The middle aged women showed a higher performance level of hygiene-oriented (4.15) and health-oriented dietary life (3.59), but a less convenience-oriented dietary life (2.57). Based on their lifestyle, 3 clusters were extracted: Low-interest dietary life meal manager, health and quality pursuit meal manager, and convenience and eating-out pursuit active meal manager. Among them, the cluster of health and quality pursuit meal manager showed the highest sustainable practices in 7 dimensions of sustainable practices in the home except for the saving practices (p<0.001). The criteria suggested from the study can be applicable to the guidelines of sustainable meal management at home. The study can also be helpful for educators to identify the education themes for improving housewife's sustainable meal practices, having different lifestyle and sustainable meal practices.

The present study aims at identifying the nature of the organizational patterns for serial management and thus providing an assitance for decision-making in regards to how the serials in an individual library be processed. The premise of the paper is that effective management is ensued from adopting proper organizational arrangement. In the first part. attempts are made to bring to the fore the problems inherent in serial management and the efforts made for possible solutions. The main portion of the paper eximines the two outstanding patterns; namely, the decentralized arrangement patterned after the traditional functions of a library and the centralized one integrating such functions as acquisition, cataloging and information service. Both are examined in light of nature, development, applicability, strengths and weeknesses. Automation is viewed as a strong force for a change in organizing serial work as it has already brought about organizational change in some large libraries. The general conclusion is that a large collection(5,000 active titles or more) has much to benefit from a separate, specialized department. which integrates the related functions; and the smaller collection can be effectively treated like the rest of the library materials, assigning a specific unit responsible for serial work and promoting an informal communication activities which would bring about coordination and coorperation for the free flow of serial work.

The article describes the results of experiments conducted on pigs to determine the effect of plutonium, which is the most radiotoxic and highly active element in the range of mixed fuel $(U_{0.8}Pu_{0.2})O_2$ fission products, on living organisms. The results will allow empirical prediction of the emergency plutonium radiation dose for various organs and tissues of humans in case of an accident in a reactor running on mixed fuel $(U_{0.8}Pu_{0.2})O_2$.

The web 2.0 is leading a rapid change of internet services. The UCC(User Created Contents) service is one of the representative internet services with web 2.0 paradigm. In this paper, we design and implement the UCC services prototype system for image and video. The proposed system does not need to install ActiveX and client programs on devices of users to edit their contents. All processes for editing UCC are conducted on the server. Our proposed system consists of the two components such as the multimedia editing subsystem and the metadata management system. They provide the API to UCC service developers or vendors. The multimedia editing subsystem supports editing for image and video, and the streaming services of video. The metadata management subsystem supports the metadata management and retrieval of image and video.

As data exchange between business partners in e-business becomes more active, obtaining and managing reliable data is emerging as a pressing issue for corporations and organizations. For the resolution of data quality, this paper proposes a framework for data quality management with its scenario. The data quality management framework consists of three phases: data quality monitoring, data quality improvement and data application, each of which has three processes. In each process, necessity, functions, roles, and relationships among processes are specified. In order for users to directly apply the framework to the business field, a business scenario is given with examples of product identification and classification code systems widely used in e-business.

The OS has the manager of the overall system operation, and has the exact information of the running system. Power management by the OS may have great impact for the optimization of the power consumption. We implement E-ACPI, an extended ACPI which is designed for an advanced power management of embedded systems. In this paper, we address (i) how we extend the exiting ACPI to E-ACPI, (ii) technical challenges to overcome in implementation, and (iii) flow we port our E-ACPI to an embedded linux system in this paper. Experimental results show that our E-ACPI is very useful and effective in practice.

The airline industry has been growing steadily since 2016 with more than 100 million air passengers, renewing the largest number of air passengers every year. Increasing air demand leads to an increase in air traffic in limited airspace, increasing the likelihood of accidents between aircraft. Due to the massive human and material damage caused by a single mistake, aviation safety is being heavily focused around the world to efficiently use limited airspace. Studies related to various human factors are underway as most of the aviation accidents are found to be caused by human factors, but research on human factors by controllers is insufficient while they are active in terms of control and operation. Given that 82% of air accidents caused by controllers are caused by human error, the importance of management of human error and changes in perception are urgently needed. This study aims to understand the seriousness of the controller's human error by analyzing the accident cases caused by the controller's human error using TEM to identify threats and errors and derive common human factors.
