We analyzed learning materials from web sites of the Ministry of Environments, the Ministry of Land, Transport and Maritime Affairs and Korea Energy Management Corporation to help people to develop and utilize web-based multimedia teaching materials. The contents of web-based multimedia teaching materials for environmental educations were generally concentrated in 304 cases of natural environments (22.1%), 250 cases of environmental contaminations (16.5%) and 187 cases of environmental preservation plans (12.4%). It did not significantly deviate from traditional teaching-learning contents being conducted focusing on environmental pollutions of the past. The types of web-based multimedia teaching materials for environmental educations were 934 cases of teaching plans (61.8%), 156 cases of documentaries (10.3%) and 128 cases of e-text information (8.5%). The web-based multimedia teaching materials by school-levels showed that there were 796 for primary schools (35.3%), 588 for middle schools (26.1%) and 320 for high schools (14.2%). It also showed that environmental education with similar contents were provided even in advanced schools. Therefore, it is believed that there needs development of various types of teaching materials while the fields of environmental education contents are covered with connectivity according to school-levels.

The purpose of this study is to explore the multi-faceted understanding and issues of science subject matter competencies from the trends of competency-based curriculum discourse, and to examine the relationship between general core competencies and science subject matter competencies. First, we examined the theoretical background of competency-based curriculum focusing on behaviorism, humanism, and its comprehensive synthesis. After that, we reviewed OECD's competency-related projects (DeSeCo; OECD Education 2030), US Next-Generation Science Standards (NGSS) and Korea's 2015 Revised National Curriculum from the viewpoint of competency-based curriculum. After that, we summarized and systematically analyzed a list of competencies, 105 general core competencies and 45 science subject matter competencies proposed by 15 important documents from home and abroad. The results of this study are as follows: First, the issues of the proper number, appropriate dimension, and how individual competencies should be unique and independent were pointed, in terms of defining and categorizing competencies. Second, it was suggested that the competency items are presented in various dimensions such as personal-micro dimension, community meso-dimension, and social-macro dimension. Meso-dimension was placed on both general core competencies and subject matter competencies. Third, in the relationship between general core competencies and subject matter competencies, the former emphasizes macro-dimension, and the latter emphasizes micro-dimension, revealing an existing gap, and where the two can meet each other is the meso-dimension. These discussions are thought to provide insight into the understanding of competencies in the national curriculum, including the 2015 Revised National Curriculum.

This study investigated the news report tendency and frame by three major Korean television networks(KBS, MBC, and SBS) in their news reports on issues involving their own interests and considering in social level. The three issues chosen for this study are 'advertising regulations for total amount', 'the reallocation of 700MHz spectrum' and 'raising TV license fee'(this issue applicable only to KBS). By using content analysis method, this study identified extremely weighted tendency toward themselves by the network television channels. They have used highly biased tone and sources to reinforce their private interests in news reports about the three controversial issues. In terms of story content, the news reports have used attribution of responsibility frame dominantly in 'advertising regulations for total amount' issue, whereas the moral frame was dominant in the other two issues.

The objectives of this study were to investigate the microbial contamination level of domestic kitchen environments and to provide information to improve food safety in 50 domestic house kitchens located in Seoul, Incheon, and Gyeonggi-do. Dishcloth, chopping board, and refrigerator swabs were examined for the presence of coliforms, Salmonella spp., Campylobacter jejuni/coli, Escherichia coli, Listeria monocytogenes, and Staphylococcus aureus. The means and standard deviations of coliform counts for dishcloths was $4.8{\pm}1.84log\;CFU/100g$, chopping boards, and refrigerator drawers were $4.04{\pm}1.53$, $4.11{\pm}1.65log\;CFU/100cm^2$, respectively. Salmonella spp. and Campylobacter jejuni/coli were not detected in all samples. E. coli were detected in 3 on the dishcloths and 1 of 50 samples in the refrigerator drawer. Listeria monocytogenes was detected in the drawer of the refrigerator in 2 of 50 samples. In the case of Staphylococcus aureus, the detection on dishcloths, chopping boards, and drawers in refrigerators was 21, 12, and 14 of 50 samples, respectively. The results of microbiological tests of domestic kitchen utensils can be used to emphasize the importance of the sanitary conditions in domestic kitchen environments.

The purpose of this study was to examine the nature of inquiry activities proposed in high school physics textbooks that were developed based on the 2009 science curriculum in Korea. The inquiry activities were analyzed using the notion of scientific practices introduced in the Science Education Framework (NRC, 2012). The results showed that the inquiry activities in the textbooks emphasized two of eight types of scientific practices including "Analyzing and interpreting data" and "Constructing explanations". In contrast, the activities required students to "ask questions" only once in a total of 291 science inquiry activities. The other types of scientific practices appeared less than 10%. Also found was that the types of scientific practices were not relevant to the way inquiry activities were used for textbook content. Implications for the curriculum and science teacher education were discussed.

Our country, which relies on maritime transport a majority of import and export trade volume and faced with unexpected accidents, it is difficult to operate the normal function of container terminal. It also caused by reliability issue raised is likely to be given a blow to the new volumes to attract and maintain existing volumes. Under this views, the container terminal is a situation that highlights the role of the harbor workers and cope with aggressive work to provide the best quality services to customers 365 days. On these grounds, the heavy work burden is passed on to the harbor workers and caused accidents every year. The study was analyzed the safety status of the container terminal under the real following the conditions as disaster status analysis, insufficient safety training circumstances and safety training from 2012 year to 2015 in the target current K.Y terminal. As a result of equipments safety training analysis, it shows that 2012 year happened 45 cases and 31 cases in 2013 year until not practicing the training over the Gantry Crane equipment. One hand 23 cases took place in 2014 while preparation training and the other intensive training period of 2015, 8 cases occurred. it shows that 2012 year happened 13 cases and 19 cases in 2013 year until not practicing the training over the Transfer Crane equipment. One hand 12 cases took place in 2014 while preparation training and the other intensive training period of 2015, 8 cases occurred. it shows that 2012 year happened 9 cases and 9 cases in 2013 year until not practicing the training over the Yard Tractor equipment. One hand 9 cases took place in 2014 while preparation training and the other intensive training period of 2015, 4 cases occurred. Because safety training of the container terminal was given to greatly impact on the mandatory safety training, self-educational enforcement and specified equipments safety training, hence the container terminal is to strengthen the safety education to prevent accidents in advance.

Prominence of speech, which is often called 'accent,' affects the fluency of speaking American English greatly. In this paper, we present an accurate prominence detection method that can be utilized in computer-aided language learning (CALL) systems. We employed pitch movement, overall syllable energy, 300-2200 Hz band energy, syllable duration, and spectral and temporal correlation as features to model the prominence of speech. After the features for vowel syllables of speech were extracted, prominent syllables were classified by SVM (Support Vector Machine). To further improve accuracy, the differences in characteristics of neighboring syllables were added as additional features. We also applied a speech recognizer to extract more precise syllable boundaries. The performance of our prominence detector was measured based on the Intonational Variation in English (IViE) speech corpus. We obtained 84.9% accuracy which is about 10% higher than previous research.
