  • Purpose: The purpose of this study was to develop an effective obesity management program for elementary school children, based on the motivation theory. Method: This study was a methodological study. A child obesity management program, based on the motivation theory was developed, a web site was made and children with obesity participated in the internet program. After the children finished the program, they evaluated the clinical validity of the program. The clinical validity was tested from Jun 12 to 16, 2006. The participants were 6 students. The evaluation tool was Keller's IMMS(Instructional Material Motivation Survey). Data were evaluated using $means{\pm}SD$ for four major components A,R,C,S (Attention, Relevance, Confidence, Satisfaction), based on ARCS in the motivation theory. Results: The program developed in this study was named 'ARCS children obesity escape', and the URL is 'http://www.119kid.co.kr'. Regarding the four components of ARCS, the overall reaction of participants showed that they were very highly motivated by this program. Conclusion: Utilizing the ARCS motivation strategies for solving obesity problems for children is an effective method to motivate the management of obesity, and can increase achievement motivation, attention, relevance, confidence, and satisfaction with the management of obesity. Thus, the program developed in this study is expected to reduce obesity in children, and become an important guide for obesity management and health improvement for children.

  • The web search engines are exposed to the issue of uncertainty because of ambiguous queries, being input for retrieving the accurate results. Ambiguous queries constitute a significant fraction of such instances and pose real challenges to web search engines. Moreover, web search has created an interest for the researchers to deal with search by considering context in terms of location perspective. Our proposed disambiguation approach is designed to improve user experience by using context in terms of location relevance with the document relevance. The aim is that providing the user a comprehensive location perspective of a topic is informative than retrieving a result that only contains temporal or context information. The capacity to use this information in a location manner can be, from a user perspective, potentially useful for several tasks, including user query understanding or clustering based on location. In order to carry out the approach, we developed a Java based prototype to derive the contextual information from the web results based on the queries from the well-known datasets. Among those results, queries are further classified in order to perform search in a broad way. After the result provision to users and the selection made by them, feedback is recorded implicitly to improve the web search based on contextual information. The experiment results demonstrate the outstanding performance of our approach in terms of precision 75%, accuracy 73%; recall 81% and f-measure 78% when compared with generic temporal evaluation approach and furthermore achieved precision 86%, accuracy 71%; recall 67% and f-measure 75% when compared with web document clustering approach.

  • This study aims to compare and analyze the types of teaching-learning activities, themes and percentage of STS contents in the area of "The Earth and the Universe" in elementary science subject following the 7th Curriculum and 2007 Revised Curriculum, identifying how STS education has changed and their features. First, the number of pages where STS appears in the 2007 revised science textbook has increased over 10% compared to the that of the 7th curriculum. In particular, the number of pages in the 5th and 6th graders increased substantially to 15% and 34%, respectively. Second, as a result of analysis on components of STS, 'applications of science', 'local and community relevance', 'social problem and issues', 'evaluation concerned fir getting and using information' were obtained in the order named for the 7th curriculum; while 'applications of science', 'local and community relevance', 'career awareness' and 'social problem and issues' were obtained in the order named for 2007 revised curriculum. Third, with regard to the analysis on theme areas, the 7th curriculum was found to cover the theme on use of natural resources most frequently, followed by environmental problem, while 2007 revised curriculum to cover environmental problem and effects of technical development most frequently, followed by space development and use of natural resources. Fourth, in the area of STS teaching activities, 'investigation activity' showed highest percentage in 7th curriculum, followed by 'analysis of data', and 'research design', while 'analysis of data' showed highest frequency of appearance, followed by "investigation activity' and 'actual activities' and 'research design' in the order named in 2007 revised curriculum, showing that the area of 'analysis of data' and 'actual activities' increased substantially compared to the 7th curriculum.

  • The author reviewed the effect of psychological factors on the development and course of cancer. Cancer is a bilogical disease, but it also has a large number of psychological aspects. There have been no reports that specific personality types had tendency to cause cancer. In some studies, however, type A personality was reported to have relevance to a higher incidence of cancer and a better prognosis. And in other studies, type C personality was reported to have relevance to a higher incidence of cancer. It was reported that people who had strong tendency to control their anger and regarded the rationality and antiemotionality in their behavior as important things were susceptable to cancer. In the course of cancer, the patients who had more positive and aggressive attitude and 'fighting spirit' to their disease tended to have a better prognosis than those who accepted their disease as fate. Some studies showed that feeling of helplessness and loss of control had a negative offset on cancer. It was reported that, in the early stage of cancer, the psychological factors had great influence on the prognosis, but in the middle and late stage, the influence decreased. For the future studies, cancer should not be regarded as a single disease and a single condition. The kinds and stages of cancer should be difined for studies. The scales for psychological evaluation for cancer patients should be sensitive and selected carefully, considering the complexity of the cancer patients mind. The need for prospective studies is emphasized. Finally, as the cured cancer patients have great difficulties in returning to their work and daily life, rehabilitation of cancer patients is also emphasized.

  • Proper and precise embedding of commercial ads within Webpages requires Ad-hoc analysis and understanding of their content. By the successful implementation of this step, both publishers and advertisers gain mutual benefits through increasing their revenues on the one hand, and improving user experience on the other. In this research work, we propose a novel multi-level context-based ads serving approach through which ads will be served at generic publisher websites based on their contextual relevance. In the proposed approach, knowledge encoded in domain-specific and generic semantic repositories is exploited in order to analyze and segment Webpages into sets of contextually-relevant segments. Semantically-enhanced indexes are also constructed to index ads based on their textual descriptions provided by advertisers. A modified cosine similarity matching algorithm is employed to embed each ad from the Ads repository into one or more contextually-relevant segments. In order to validate our proposal, we have implemented a prototype of an ad serving system with two datasets that consist of (11429 ads and 93 documents) and (11000 documents and 15 ads), respectively. To demonstrate the effectiveness of the proposed techniques, we experimentally tested the proposed method and compared the produced results against five baseline metrics that can be used in the context of ad serving systems. In addition, we compared the results produced by our system with other state-of-the-art models. Findings demonstrate that the accuracy of conventional ad matching techniques has improved by exploiting the proposed semantically-enhanced context-based ad serving model.

  • This study is to evaluate the 'Private antidesertification afforestation support project' in the Kubuqi Desert through a survey of local residents and interviews with relevant personnel. Based on this survey, gender, age, and occupational differences in perception of the project were analyzed. In addition, the project was evaluated based on the OECD/DAC criteria using survey results and in-depth interviews with the relevant personnel. The survey analysis results show that the participants answered most of the questions positively, claiming that they were receiving social, economic, and environmental benefits through the project. However, most of the participants answered negatively to questions regarding the understanding of the project and relevant information. Gender differences in perception of the project were not found, whereas, age and occupational differences in perception were found. Older age groups showed higher levels of perception. Participants in the agro-livestock industry and office workers showed higher levels of perception compared to middle/high school students, the unemployed and college students. Teenagers, in particular, showed the lowest level of perception of the project, and thus, promotional activities targeting teenagers should be conducted in the future. Results of this evaluation of the project based on the OECD/DAC's five criteria (relevance, effectiveness, efficiency, impact, and sustainability) showed that the project operated effectively for the most part.

  • Background: Self-reported low back pain (LBP) has been evaluated in relation to material handling lifting tasks, but little research has focused on relating quantifiable stressors to LBP at the individual level. The National Institute for Occupational Safety and Health (NIOSH) Composite Lifting Index (CLI) has been used to quantify stressors for lifting tasks. A chemical exposure can be readily used as an exposure metric or stressor for chemical risk assessment (RA). Defining and quantifying lifting nonchemical stressors and related adverse responses is more difficult. Stressor-response models appropriate for CLI and LBP associations do not easily fit in common chemical RA modeling techniques (e.g., Benchmark Dose methods), so different approaches were tried. Methods: This work used prospective data from 138 manufacturing workers to consider the linkage of the occupational stressor of material lifting to LBP. The final model used a Bayesian random threshold approach to estimate the probability of an increase in LBP as a threshold step function. Results: Using maximal and mean CLI values, a significant increase in the probability of LBP for values above 1.5 was found. Conclusion: A risk of LBP associated with CLI values > 1.5 existed in this worker population. The relevance for other populations requires further study.
