This study was carried out to examine the tendency about the relative importance of STS education of the 6th and 7th primary science curriculum. The results of the research are as follows. Primary science textbooks in the 6th curriculum, average 13.3% of the total pages was assigned to STS contents but it is increased to 24.2% in the science textbooks of the 7th curriculum. STS constituents of the 6th primary science textbooks come out orderly applications of scientific knowledge(47.1%), relevance of a community(40%), social problems and issues(11.8%). Of the 7th science textbooks, the contents about applications of scientific knowledge amount to 67.1% of the total STS constituent and relevance of a community(32.2%) rank behind it. The contents of other components are not enough. The 6th science textbooks contents about the effect of technological development amount to 35.3% of the total STS subject area, and environmental quality(20.0%), natural resource(15.2%), energy(11.8%), sociology of science(11.8%) ranks behind it. In the 7th science textbooks ranking is the effect of technological development(42.3%), natural resource(17.3%), energy(12.5%), sociology of science(12.5%), environmental quality(20.0%). There are few contents about population, human engineering and space research and national defense in the science textbooks.

Mobile phone carriers face challenges from three synergistic dimensions: Wireless, social, and mobile. Despite significant advances that have been made about social networks and human mobility, respectively, our knowledge about the interplay between two layers remains largely limited, partly due to the difficulty in obtaining large-scale datasets that could offer at the same time social and mobile information across a substantial population over an extended period of time. In this paper, we take advantage of a massive, longitudinal mobile phone dataset that consists of human mobility and social network information simultaneously, allowing us to explore the impact of human mobility patterns on the underlying social network. We find that human mobility plays an important role in shaping both local and global structural properties of social network. In contrast to the lack of scale in social networks and human movements, we discovered a characteristic distance in physical space between 10 and 20 km that impacts both local clustering and modular structure in social network. We also find a surprising distinction in trajectory overlap that segments social ties into two categories. Our results are of fundamental relevance to quantitative studies of human behavior, and could serve as the basis of anchoring potential theoretical models of human behavior and building and developing new applications using social and mobile technologies.

Purpose: The purpose of this study was to develop an instrument to measure nursing professional values. Method: Forty preliminary items were selected by classifying 223 basic items extracted via a literature study and in-depth interviews of subjects and testing the relevance of their contents. In order to verify the reliability and relevance of the preliminary instrument, data was collected from 504 nurses in 3 general hospitals. Result: As a result of the item analysis, 29 items were selected from a total of 40 items. Five factors were extracted by factor analysis, and the total variance was $51.5\%$. For the explanation of variances by factors, the 1 st factor, 'self-concept of the profession' accounted for $14.8\%$, the 2nd factor, 'social awareness' $12.1\%$, the 3rd factor, 'professionalism of nursing' $9.8\%$, the 4th factor, 'the roles of nursing service' $9.1\%$, and the 5th factor, 'originality of nursing', $5.6\%$. Cronbach's Alpha of those 29 items was .9168, which was high. Conclusion: This paper is meaningful in a way that it developed a tool capable of measuring nursing professional values, which reflects the characteristics of our country. In order to re-verify the relevance and stability of this tool, it is necessary that comparative studies should be conducted.

To delve into the semantic gap problem of the automatic video summarization, we focused on an endogenous ERP responses at around 400ms and 600ms after the on-set of audio-visual stimulus. Our experiment included two factors: the topic exploration of experimental conditions (Topic Given vs. Topic Exploring) as a between-subject factor and the topic relevance of the shots (Topic-Relevant vs. Topic-Irrelevant) as a within-subject factor. For the Topic Given condition of 22 subjects, 6 short historical documentaries were shown with their video titles and written summaries, while in the Topic Exploring condition of 25 subjects, they were asked instead to explore topics of the same videos with no given information. EEG data were gathered while they were watching videos in real time. It was hypothesized that the cognitive activities to explore topics of videos while watching individual shots increase the amplitude of endogenous ERP at around 600 ms after the onset of topic relevant shots. The amplitude of endogenous ERP at around 400ms after the onset of topic-irrelevant shots was hypothesized to be lower in the Topic Given condition than that in the Topic Exploring condition. The repeated measure MANOVA test revealed that two hypotheses were acceptable.

We examine the effects of the sustainability report (SURE) and investment decision on share price (SPRC). Explore whether the sustainability report changes the value-relevance of financial accounting variables indirectly. It is evident that the number of banks is only 12, which are all banks in Saudi Arabia, and we have included all of them in the final sample. Moreover, the same number of banks applied for the analysis concerning the accounting variables. This article utilizes a panel dataset from a sample of Saudis registered banks from the first quarter of 2014 to the last quarter of 2018. We utilize a balanced sample that contains all banks listed in Tadawul, 240 observations. Run GLM regression to tests the relationships. Findings exhibit that investors value the complementary disclosure of accounting information provided in SURE, and this disclosure produces a positive effect on SPRC. The SURE figure is robustly significant, suggesting that the market assigns a positive-significant correlation to the further information in the SURE. The indirect effects show that BPS×SURE is a positive-significant effect on SPRC, whereas EPS×SURE is positively-insignificant. The analysis shows that SURE's value relevance conforms through Saudis Banks, consistent with the hypothesis that diverse institutional perspectives probably influence the value-relevance of SURE.

The purpose of this paper was to compare and analyze the elementary curriculum and textbook integration of social studies in Korea, USA, and England in terms of content integration and to make suggestions for the improvement of Korean social studies curriculum and textbooks. For this study, social studies curriculum and textbooks of three different countries were analyzed according to the three criteria: sequence, types and focus of integration. In this comparative study, five suggestions were made for the improvement of the Korean elementary social studies curriculum and textbooks. First, Korean social studies curriculum should have a subject focus at each grade level. Second, it is recommended that Korean social studies curriculum should present clear interrelations among geography, history, and civics at each grade level. Third, Korean social studies curriculum needs to have diverse criteria on which to select and organize themes. Fourth, Korean social studies textbooks need to have increased number of interdisciplinary large units. Fifth, it is necessary that the authors of Korean social studies textbooks integrate contents in consideration of students' life context in order to raise the relevance of the contents of history and geography.

A growing number of studies have examined the relevance and impact of social media in building organizational resilience, which the ability to recover from a crisis, in the field of emergency management. However, few studies have assessed how these emergency response organizations perceive their own use of social media in crisis situations. In attempting to fill this gap, this study conducted a structured survey with emergency-response organization representatives in Seoul, South Korea, to examine how such organizations evaluate their utilization of social media in an urban emergency situation and how their social media uses are related to promoting organizational resilience during adverse events such as a flood. Overall, the findings imply that organizations are not yet taking full advantage of social media. Respondent evaluations of their own social media use in all three assessment areas-information provision, information dissemination, and emotional messages-were not satisfactory. However, their perceptions of how well they utilize social media were positively related to how they view their organizational resilience. Therefore, it may be that these organizations realize the powerful role of social media in building organizational resilience but lack the knowledge and experience to make the best use of social media services.

Background: Safety management is required to ensure health and safety of personnel in Norwegian fish farming. However, few studies have addressed the status and practical relevance of this risk-reducing measure. Methods: This article provides new knowledge through interviews with 35 employees at different company levels, addressing perceptions of various safety management activities according to managers and operational personnel. Results: The interviews show that managers and operational personnel at fish farms agree that the quantity of measures aimed to improve safety has increased in recent years. However, some activities are perceived to have higher practical relevance than others. In general, measures that fit well with the practical reality are well received by the employees at the fish farms. Conclusion: Suggested improvements include involving operational personnel in the design of procedures, considering all risk dimensions that may affect occupational health and safety, and challenging the value of specific safety activities based on a detailed knowledge of the distinctive characteristics of work practice in fish farming.

Over the last decade, the field of Southeast Asian Studies has been inundated with issues of its "territory" (or the definition of what comprises Southeast Asia), relevance and future. The methodology of approaching Southeast Asian Studies has also come under constant scrutiny providing much fodder for debate. One significant suggestion was that the field of Southeast Asian Studies should "break out of the comfort zone" (Van Schendel, Bijdragen, 2012:168(4)). This paper will explore some of the ways of approaching Southeast Asian Studies beyond that comfort zone by examining other/alternative units of studying Southeast Asia in place of the traditional (or statist) perspectives that tend to confine the field within the scope of the national/nation-state boundaries. The paper will also provide some personal observations of the author on the current state and limitations to teaching and researching Southeast Asian Studies in the region.
