Because of ambiguous and abundance of the Web log file, the least decision making model based on rough set theory was presented for Web mining. And an example was given to explain the model. The model can predigest the decision making table, so that the least solution of the table can be acquired. According to the least solution, the corresponding decision for individual service can be made in sequence. Web mining based on rough set theory is also currently the original and particular method.展开更多

This study utilized the Sensewear (SWA) armband and a diet journal to promote adolescents' EB knowledge and motivation. Methods: Ninety sixth graders were randomly assigned into the experimental group (n = 46) who utilized SWA and diet journal for 7 consecutive days or the control group (n = 44) who did not. Both groups were pre- and post-measured on EB knowledge, situational interest, and weight. The experimental group was tracked on motivation effort, energy expenditure (EE), and energy intake (EI). Results: EB knowledge significantly increased and situational interest remained stable (except for total interest and enjoyment) over time, but these changes did not favor the experimental group. Situational interest and motivation effort were correlated with EE, EI, and/or EB. Conclusion: Tracking EB using the SWA and diet journal is motivating but has limited efficacy in promoting adolescents' EB knowledge. Using these two tools as educational technology in conjunction with a focused, systematic, and educational approach has the potential to leverage adolescents' EB knowledge, motivation, as well as behaviors for living an energy-balanced lifestyle.展开更多

This philosophy is clad in different ways by the people as they are continuously at work to give meanings to their creative activities. Proverbs are one of the most relevant expressions of human wisdom and knowledge of nature, psychology, and reality for the Hausa people of Northern Nigeria; however, the images that are presented in the proverbs are culturally defined and they may differ from place to place, as well as from generation to generation. Proverbs are capable of a variety of meanings, according to how and when they are used. These findings have revealed that many popular and interesting Hausa proverbs tell a condensed story; these stories give vivid illustrations which help the hearer understand the proverbs. In this paper, the author attempts a deep intellectual analysis into the story-lines behind the emergence of some selected Hausa proverbs, with a view to comprehending and propagating embedded ideas and cultural principles or philosophies that may be relevant for contemporary social usage.展开更多

Unlike other researches, this paper analyzes the conversion process of carbon element in the ocean from the qualitative viewpoint. There are many complex roles in the ocean carbon cycle, and it is hard to represent the case that an entity plays different role in different environment. An ontology technology Hozo role theory developed by Osaka University Mizoguchi Laboratory is proposed as a solution. The basic concepts and representation mode of Hozo role theory is introduced. The conversion process of ocean carbon cycle is abstracted and an ontology model using Hozo role theory is proposed. Instead of comprehensive common ontology construction method, we propose our own ontology development steps. Then an ontology about ocean carbon cycle is built in order to describe and share the basic knowledge of ocean carbon cycle. A knowledge base of material circulation is proposed based on the ontology. Its construction framework is described and some knowledge base query examples are also illustrated. Conclusions show that the role theory can effectively solve the problem of multirole description in ocean carbon cycle, and knowledge reasoning based on ontology is also effective.展开更多

Administrative records of some institutions and information obtained from published articles in journals and text books were used for the study. Records indicate that GIS is relatively young in Nigeria and in terms of development, it is at its youthful stage. The adoption and use of GIS is low at both Federal and State Government levels. However, factors such as, lack of political will, shortage of experts to train the professionals, lack of standardization of digital data, database development and management problems, institutional constraints, security implications of digital maps and poor funding have been inhibiting full adoption, implementation and use of GIS in Nigeria. There is the need to develop a GIS vision in the country and government should formulate policy and create enabling environment for the adoption and implementation of the new technology.展开更多

The study utilizes methodological triangulation inclusive of textual, document, and value chain analysis. The Japanese government has progressively appreciated the intrinsic value of the media content from both a commercial and cultural context and the loss of value in unregulated segments of the regional market. In 2003, they established an Intellectual Property Strategy Group to support and promote the Japanese media content business. There has been a continuum of policy development since then to protect and amplify the financial value of Japanese media products. All of the developments in media industry are fuelled not only by government regulations, the imagination of talented artists and writers, and the growing regionalization and internationalization of the industry but also the "bottom line" emerging from the value chain. The recognition of the need for sustaining profit growth to continue the viability of original and remade content in Japan is paramount for Japan.展开更多

Purposive, multistage and random sampling techniques were employed in selecting a sample size of two hundred and forty (240) respondents. Structured interview schedule was used for data collection, while percentages, mean ratings and factor analysis techniques were employed for analysis. The findings show that majority (64.6%) of farmers were within the ages of 40-59, while majority (67.9%) had either FSLC or WASCE/SSCE/GCE/OL qualifications. The farmers reported that the major soil erosion control measures used were strip cropping (M = 4.8) and making of ridges against slopes (M = 4.7). The study reported that poor group affinity, inadequate institutional support and inadequate technical knowhow were constraints to soil erosion control in southeast, Nigeria. The study highlighted implications for sustainable development in agriculture and environment on organizational overhaul in extension, participatory extension policy on farmers groups and institutional re-orientation and synergy between Universities, Agricultural Development Programme (ADP), Ministry of Agriculture (MOA) and Local Government Councils. In conclusion, success in soil erosion control and sustainable development in agriculture and environment in southeast, Nigeria depends on the extent issues raised and implications highlighted can be addressed. The study recommends improved funding support to extension, participatory extension training and contacts with farmers' groups and groups' resources management.展开更多

Methods:A total of 30 eligible cases were treated by needling Shenting (GV 24), Baihui (GV 20), Dazhui (GV 14), Fengfu (GV 16), Mingmen (GV 1) and Yongquan (KI 1). Upon arrival of qi, the G6805-II electric stimulator was connected to Shenting (GV 24) and Baihui (GV 20) (one pair), to Dazhui (GV 14) and Fengfu (GV 16) (one pair) and to bilateral Yongquan (KI 1) (one pair) for 25 min, using continuous wave at the frequency of 2-100 Hz and voltage of 2-4 V. With a tolerable intensity, the EA was conducted once a day for 10 d (one treatment course). There was a 3-day interval between two courses. After three courses, the therapeutic efficacies were evaluated using the mini-mental state examination (MMSE), revised Hasegawa dementia scale (HDS-R), activities of daily living (ADL) and neurological function defect scale (NFDS). Results:After EA treatment, the MMSE and HDS-R scores were significantly increased (P〈0.01) and the ADL and NFDS scores were significantly decreased (P〈0.01). Conclusion:EA is effective for AD and can improve the overall intelligence and repair neurologic deficits in AD patients.展开更多
