This descriptive study looks into the levels of BMI, dietary habits, body image, and eating attitudes which have a major impact on the obesity management of female college students. A total of 173 female college students from the same school participated in this study by filling out a self-administered questionnaire investigating actual conditions. The average age of the participants was 19.5 years old and the average BMI was $21.8kg/m^2$. There were statistically significant differences in dietary habit at home (t=2.957, p=.004), eating attitudes BMI (F=5.324, p=.006), actual body image within perceived body esteem and BMI (F=36.979, p=.000), level of state body esteem BMI (F=11.539, p=.000), level of eating attitudes BMI(F=5.324, p=.006). Among the relationships between variables, the higher the BMI, the higher the score for perceived body esteem and problems concerning eating attitudes became prevalent. The higher the actual body image score, the lower the state body esteem and problems concerning eating attitudes became prevalent. Therefore, there is a need for education that enhances positive body image and eating attitudes in order for female college students to manage obesity due to dietary habits.

This study was attempted in order to examine about influence of knowledge and attitude toward CPR(Cardiopulmonary Resuscitation) in elementary school students of some regions upon self-confidence. The aim is to be conducive to effective performance and self-confidence in CPR for cardiac arrest patients. We carried out targeting 381 elementary school students who attend 4 schools in J city and K city of J province from June 25 to July 15, 2009. The statistical processing was done by SPSS WIN 12.0 Version. The statistical significance was set to p<.05. As for correlation between variables of cardiopulmonary resuscitation characteristics with knowledge, attitude, and self-confidence, the appearance of acquiring information(r=.174, p<.01), the appearance of experiencing cardiopulmonary resuscitation(r=.143, p<.01), the appearance of educating cardiopulmonary resuscitation(r=.164, p<.01), necessity for education(r=.184, p<.01), knowledge(r=.342, p<.01), and attitude(r=.736, p<.01) showed correlation with self-confidence. As for influence of knowledge and attitude toward cardiopulmonary resuscitation upon self-confidence, the attitude($\beta=.703$, t=17.884, p<.01) had significant influence upon self-confidence. It is necessary to arrange educational program of cardiopulmonary resuscitation, to distribute effective manpower, and to provide elementary school students to cope with emergent situation.

Rainfall-induced landslides are caused by reduction of effective stress and shear strength due to rainfall infiltration. In order to analyze the susceptibility of landslides, the statistical analysis approach has been used widely but this approach has the limitation which cannot take into account of landslide triggering mechanism. Therefore, the physically based model which can consider the process of landslide occurrence was proposed and commonly used. However, the most previous physically based model analyses evaluate and consider the strength characteristics for saturated soil only in the susceptibility analysis. But the strength parameters for unsaturated soil such as matric suction should be considered with the strength parameters for saturated soil since the shear strength in unsaturated soil also plays important role in the stability of slope. Consequently this study suggested the modified physically based slope model which can evaluate strength characteristics for both of saturated and unsaturated soils. In addition, this study evaluated the thickness of saturated part in slope with rainfall intensity and hydraulic characteristics of slope on the basis of physically based model. In order to evaluate the feasibility, the proposed model was applied to practical example in Jinbu area, Gangwon-do, which was experienced large amount of landslides in July 2006. The ROC graph analysis was used to evaluate the validation of the model, and the analysis results were compared with the results of the previous analysis approach.

Teachers' perceptions about curricular objectives are very important to achieve given educational objectives. This study examined teachers' perceptions about priority and hinderance of science objectives. The national science curriculum stated four areas of objectives: inquiry, knowledge, attitude, and STS. A total of 76 elementary and 217 secondary teachers were responded to questionnaire developed for this study. Non-parametric statistics, such as Friedman test, Kruskal-Wallis test, and chi-square test were used by using SPSS/PC program. Teachers in general ranked the inquiry first among the four areas at their perception on the national curriculum, on themselves, and on their instructions. Elementary teachers ranked inquiry higher than secondary science teachers, while secondary science teachers ranked knowledge higher than elementary teachers. As factors hindering teachers from achiving the objectives, elementary teachers pointed out overcrowded classroom and secondary science teachers pointed out college and university entrance examination respectively.

Purpose: This study was conducted to understand the public awareness of landslide and check dams in 2015-2020 using the big data platform 'Hyean' and to confirm the utilization of this platform in disaster prevention areas. Method: The total amount, number of detection by period by media, and affirmative and negative trends of a search for 'landslide' and 'check dam' in 2015-2020 were analyzed using a keyword search of 'Hyean.' Result: There is significant lack of public awareness of check dam compared to landslide, and the trend is more noticeable in the conspicuous gap of data amount between the news and SNS media. The number and the timing of the search for 'landslide' coincided with the actual occurrence of landslide, while the detection of 'check dam' was less related to it. Relatively affirmative preception for the check dam is inferred, but it was difficult to confirm accurate statistical affirmative and negative trends in the disaster prevention field using 'Hyean.' Conclusion: Unlike the experts who expect positive public awareness of check dam, the statistic results show that the public awareness of the check dam as an effective countermeasure against landslide was extremely low. Active promotion of erosion control projects should be carried out first, and a balanced sample survey should accompany online and periodic field surveys. Since there is a limit to grasping the effective perception in the field of disaster prevention area using 'Hyean', it should be very cautious to establish local/governmental policies using it.

Foreign word transliterations are not consistently used in documents, which hinders retrieving some important relevant documents in exact term matching information retrieval systems. In this paper, a meta search method is proposed, which expands and refines relevant variant queries from an original input foreign word transliteration query to retrieve the more relevant documents. The method firstly expands a transliteration query to the variants using a statistical method. Secondly the method selects the valid variants: it queries each variant to the retrieval systems beforehand and checks the validity of each variant by counting the number of appearance of the variant in the retrieved document and calculating the similarity of the context of the variant. Experiment result showed that querying with the variants produced at the first step, which is a base method of the test, performed 38% in average F measure, and querying with the refined variants at the second step, which is a proposed method, significantly improved the performance to 81% in average F measure.

The purpose of this study is to make an empirical analysis of the influencing factors of consumer purchase intention of ginseng products, one of the specialties of jilin province in china, on the basis of expanding the theoretical model of planned action at the level of perceived value, so as to better grasp consumer purchase behavior of ginseng products. In this study, a questionnaire survey was conducted among ginseng product consumers living in jilin, and 360 valid samples were statistically analyzed using SPSS 23.0.The analysis results show that behavioral attitude, subjective norms, cognitive behavior control, price value, emotional value and social value have considerable influence on consumers' intention to buy ginseng products, and the influence of perceived value is significantly greater than the three factors of planned action theory. Moreover, the functional value has little influence on consumers' intention to buy ginseng products.

This study observed how school resilience of adolescents from multi-cultural families was influenced by risk factors and protective factors. Furthermore, this study verified which protective factor moderated factor to exert positive influence on school resilience. The results showed that risk factors negatively influenced school resilience and protective factors positively influenced school resilience with statistical significance. The results showed that 'high self-esteem' moderated 'negative rearing attitude', 'positive attitude' moderated 'negative rearing attitude' and 'parent conflict', whereas 'teacher support' moderated 'negative rearing attitude' to significantly increase school resilience. The study suggested a measure that can reduce risk factors to increase school resilience of children from multi-cultural families according to the moderation relationship between protective factors and risk factors.
