  • Willingness-to-pay (WTP) for pork produced by quality test was determined using a contingent valuation method. Three model studies including a dichotomous-choice and two double dichotomous-choice types were conducted. The respondents in this study appropriately understood the contingent valuation and the suggested price was significant as a characteristic variable. The results imply that there is lower chance to select pork produced by the quality test, as the price difference is greater between conventional and quality-tested pork. WTPs in double and single contingent valuation models were 735 and 547 won/100 g, respectively. WTP was increased with increasing the educational level of respondents. The average WTPs analyzed by convariate were 1,015 won/100 g for double contingent valuation and 580 won/100 g for single contingent valuation. Considering the minimum price of WTP of pork produced by quality test (547.4 won/100 g), the total economic value was estimated to be 5,173,600 million won and per capita customer value was 106,000 won. Therefore, providing an institutional strategy for pork quality test will be beneficial for the consumers.

  • The purpose of this study was to develop understanding-oriented materials based on backward course design model and analyze their effects on 'biology and environment' unit of elementary school science. Backward Design starts from a specification of learning outcomes and decisions on methodology and syllabus are developed from the learning outcomes. This method has a strength maintaining consistency between educational contents-evaluation-learning activities and also promoting student's authentic understanding. The 78 students 6th graders participated in this experiments. Data was collected using project activities, the science academic emotion scale and academic achievement. The collected data was analyzed by t-test and ANCOVA analysis using the SPSS 23 statistical program. The following major conclusions were drawn on the basis of data analysis. First, the experimental group showed a relatively accurate understanding of the contents of science but they could not produce creative output in two project activities. Second, the interaction effect of the instruction based on backward curriculum design and science academic emotion was not significant statistically. Third, the experimental group showed a significant improvement in the academic achievement of 'biology and environment' unit.

  • This study compares and analyzes the characteristics and effects of various educational contextual variables according to students' achievement level and gender groups based on the results of PISA 2015 science domain. PISA 2015 included additional variables about teaching-learning and affective characteristics in the field of science, because science was the main domain of PISA 2015. The results of the mediation analysis using a multiple group structural equation model showed that the environment and strategy for the teaching and learning had a positive effect on the affective characteristics, and also positively affected science achievement through the mediator of the affective characteristics. Particularly, the environment and strategy for the teaching and learning was the most effective in improving the affective characteristics for the low achievement group. It was found that the difference of the mediated effect between achievement level groups was statistically significant, but that between male and female students was not. Therefore, the appropriate the environment and strategy for the teaching and learning will need to be emphasized consistently to improve students' cognitive and affective achievement. The implications and suggestions of these results were discussed.

  • This research analyzed 168,010 cases of death of the aged over 65 from 244,867cases of death excluding 7 unknown age cases from 244,874 all age cases of death by using the death data of the National Statistical Office for 2007 to figure out factors affecting the quality of causes of death statistics of the aged and to suggest the ways of improving the quality of death statistics of the aged in korea. This research tried to derive factors affecting ill-defined cause of death category in acordance with WHO's guidelines and to find causes of lowering the accuracy of causes of death statistics of the aged. This research identified the problems of causes of death statistics of the aged by using both demographic characteristics such as sex, age, marital status, educational attainment, residential region, region size and factors of death items as independent variable to find causes of ill-defined cause of death of the aged. Logistic regression analysis was executed to calculate the hazard ratio about the ill-defined causes of death of the aged and multiple regression analysis was conducted to derive factors affecting the ill-defined cause of death by regional groups through using these independent variables such as the component ratio of over age 65, female death rates, doctors insitutions rate, medical institutions rate, attaching rates of death certificate by neighborhood. As a results of this research, R-code was the highest of ill-defined causes of death, accounting for 82.1%, and senility death(R54) of R-code was the highest, accounting for 91.2%. through subdivided order distribution of the ill-defined causes of death of the aged. As ill-defined causes of death by regional groups, attaching rates of death certificate by neighborhood was the most important factor(p<0.05) and also showed regression model's description with 83.8% ($R^2$=83.8%). Furthermore, Jeon-nam was the highest in the regional groups and these regions such as Je-ju, Jeon-buk, Chung-nam were not only attaching the death certificate by neighborhood but also were high at the rate of ill-defined causes of death. Therefore, this research found that both reconsideration about death certificate by neighborhood and education for doctors who write death certificate were needed the most.

  • This study is to understand gifted students' suicidal ideation and its related variables among gifted students. For this, this study explores the relationship between maladaptive perfectionism of gifted students and suicidal ideation, confirming mediating effects of depression and academic stress. For the study 320 middle school students who were identified as the gifted at a gifted education center affiliated with the university. The results are summarized as follows. First, the fit of measurement model was found to be ${\chi}^2$=228.571(df=110, p=.000), CFI=.972, TLI=.966, RMSEA=.058, indicating most of fit indexes were acceptable. Second, suicidal ideation was found a significant positive relationship with maladaptive perfectionism, depression, academic stress. Third, as a result of examining path coefficient, it was found to be influenced significantly by all of the path from maladaptive perfectionism to depression and academic stress, the path from depression to suicidal ideation, the path from academic stress to suicidal ideation. However, the path from maladaptive perfectionism to suicidal ideation was found to be statistically insignificant. Fourth, the result showed that depression and academic stress worked as complete mediators between maladaptive perfectionism and suicidal ideation. These findings give useful information about affective aspects of gifted adolescents in hard circumstances. The results of the study will be helpful in devising consultation and educational programs for the gifted who are in danger of suicide.

  • Form the observation that the successful management and operation of university websites brings about university branding effects, this paper attempts to identify the problems in relation to evaluation elements of university homepages and establish a new evaluation model that allows us to grasp the importance and priority of phased evaluation elements. In particular, we tried to secure the objectivity of the importance of department homepage evaluation elements by using AHP(Analytic Hierarchy Process). Our analysis shows that among 29 evaluation elements of department homepage, mobile service, curriculum, description of department's characteristics, guide to homepage usage/accessibility to site map and differentiated educational method were considered to be relatively important whereas the relative importance of department's slogan, differentiated image and identity, linkage to SNS, Q&A bulletin board, operation of department community, and FAQ was low. Based on the findings from our analysis, we present the basic foundation for successful management and operation of university department homepages along with a few suggestions for vitalizing those hompages.

  • This study has shown that geography teachers need the professionalism in a Teaching and learning aspect. Together with the transition of epistemology and the operation of the Subject Matter-based curriculum, etc the demand for professionalism of teachers is much higher than ever. But the less discussion about what the professionalism of geography teachers based on subject traits and its components are has been mentioned. Especially the previous studies related with geography teachers usually distinguished the contents from the methods in the geography teaching in a dichotomy and tried to apply to a class model in the theoretical aspects, so they $didn't^{\circ}{\varnothing}t$ present the enough measures to improve the professionalism of geography teachers in the synthetic aspects. In this study, after I found the components of professionalism required to geography teachers in a teaching and learning, I tried to present measures to improve the professionalism of geography leathers in the macroscopic aspects. The geography teacher should be a teacher to design a region as a process than a result, and a teacher as a reflective practitioner than a technical practitioner. The improvement of professionalism should be achieved through the process of cooperation with an educational reflection in the individual aspects.

  • This research aims to find directions for character education in science education and to analyze Nature-Study theoretically as one of the ways to implement character education in science education. In order to accomplish this, references for character education were collected and analyzed to derive the directions for character education in science education, and then the results were verified by expert workshops composed of 2 science education experts and 4 PhD students. Through the consideration of references for Nature-Study in terms of character education, we supposed to confirm that Nature-Study is an efficient way to implement character education in science education. The research resulted in the following: First, science education should establish it's own role in character education by expanding the domains of value and realizing practice-centered character education. Accordingly, 'Expanded model of character education (The domains of the value)' was developed on the basis of 'formation of relationships' with 'nature & environment, spiritual object' and 'The practice-centered character manifested mechanism' empathized 'formation of relationships' and 'practice' was also diagramed. Second, Nature-Study empathized 'Science Education through Nature' can be one of the efficient ways to implement character education in science education. Nature-Study corresponds with the directions of character education in science education because Nature-Study aims for character education in it's educational purpose and emphasizes 'formation of relationships' with 'nature & environment' and 'practice' in the real world. In conclusion, science education should establish it's own role in character education by expanding the domains of value and realizing the practice-centered character education and Nature-Study is efficient ways to implement character education in science education.
