The purpose of this study is to analyze the perception on science and scientists of the teachers who are engaged in the special education for the scientifically gifted, science-gifted students and their parents. For this study, 34 teachers, 222 students and 107 parents answered the questionnaire of the perception on science and Draw-A-Science-Test (DAST). The result showed that the three groups generally had a sound recognition but the score of recognition about a 'nature of science' was lower than other domains. The science-gifted students had less cognition about 'science and society' than their teachers and parents, but they had more positive perception about 'science learning' than their parents significantly. All of the three groups had the stereotyped image of scientist. About the internal images of scientists, three groups had a similar perception, and they showed higher scores in the cognitive aspect than emotional or ethical aspects. And the science-gifted students showed the significantly higher scores than their teachers and parents in diligence, imaginative power, concern about other people, respect for other's opinion, humor, artistic sense, respect for human, desire for peace. Three groups turned out to be influenced by movie, science journal, and biography as a source of scientist's image, but their contribution was different among groups.

Recently, ICT environments have been increasingly developed and the pattern of the war also has been changed to NCW. The development of communication and network technology, for example, C4I and TDL(Tactical Data Link), has been prosperous and rapid. But the geospatial intelligence field which is the basis of the network frames relatively has not been developed. The purpose of this paper is to foster the geospatial governance in terms of the defense perspective. In order to do that, this paper deals with the U.S. Intelligence Community(IC) and the U.S. Army Global Information Grid(GIG), LandWarNet and those could be good examples of roles and statuses of geospatial intelligence. IC has been produced essential intelligence which is required for policymakers and military leaders. IC has several stove-piped intelligence process systems which have been separately developed and competed. And so as to complete GIG, the U.S. Army adopted LandWarNet. The U.S. Corps of Engineers organized the Army Geospatial Center(AGC) on 1 October 2009 to support LandWarNet. In order to develop NCW, we should recognize geospatial intelligence as the basis of network framework and make a central leading organization of defense geospatial intelligence. The mission of Korea Defense Geospatial-Intelligence Agency should be changed from producing GEOINT to a strategic GEOINT agency. The Army should organize a laboratory of geospatial intelligence field. The mission of producing GEOINT should be transferred to a geospatial intelligence battalion which is newly organized.

The aim of this study was to identify the status of health functional food consumption of working women. The 558 subjects of the study were aged between 10-60 years, and had previous experiences of consuming health functional foods. The majority of the subjects lived in Seoul, and some lived in the Gyeonggi Province. The most prevalent goals that the subjects hoped to achieve by consuming health functional foods were improvement of physical health status and reduction of exhaustion. Other goals included supplement of nutrition, and prevention or treatment of diseases. Those who were older or who possessed a high BMI spent more expenses on health functional foods, and showed a higher intake frequency as well as longer periods of consumption. Subjects placed in the older group showed a lower level of knowledge related to functional foods, which turned out to be statistically significant. Most of the respondents answered that their knowledge related to functional foods was picked up from listening to others. In conclusion, we were able to observe that groups with elder working women and high BMI show higher consumption and expense rates of health functional foods, as well as longer periods of consumption. However, they show a minimum level of knowledge related to functional foods. According to our results, these subjects should seek practical help in order to select functional foods that will aid their health, and learn the proper method of consumption. In order to reduce inaccurate consumption of health functional foods, it is imperative that more in-depth study is carried out in this field.

The purpose of this study is to analyze classroom norms formed in inquiry activities of elementary science classes and to consider about the actual problems in enacting school science inquiry. Focusing on the inquiry activity cases of two classes, the data were collected through classroom observation, student interview, teacher interview and questionnaires. Firstly, classroom norms were categorized into three categories theoretically: norms for behavior guidance; general academic norms; and scientific inquiry academic norms. The subcategory norms of each category were extracted inductively and the features, the causes of formation, and the influences on inquiry of each norm were also analyzed. Based on the analyses on classroom norms, the researchers identified three actual problems in enacting school science inquiry. First, the collective traits of school science inquiry caused structural problems in science classrooms. Second, teachers used their authorities in different ways according to phases of instructions. Third, the conflict cases were reported between general values for education and specific values for science inquiry. Educational implications are discussed in terms of the practices of school science inquiry and of the understanding classroom phenomena.

In this study, we investigated the features of using smart devices in socioscientific issues (SSI) debate classes. Twenty-seven high school students in Gyeonggi-do participated in this study. The processes of the SSI debate classes with smart devices were classified into five stages: data searching, data sharing, summary and organization of data, debate in the classroom, and online debate. Then some features at each stage were identified. It was found that they collected self-directed and in-depth data while reflecting their knowledge and experience, and selected data which were easy to understand at the stage of data searching. The specificity and validity of the evidences gathered and the clarity of the sources were improved at the stage of data sharing, although they shared more data offline than online. They organized their data by using paper rather than smart devices at the stage of summary and organization of data. Most of them failed to use the summary in debate. They argued and refuted based on concrete grounds at the stage of debate in the classroom, which raised students' interest in debate and led students to participate actively. At the stage of online debate, they were able to rearrange and review the arguments of both sides, and the participation of the students who were passive in classroom debate was enhanced. Based on these results, we suggest some effective teaching methods for SSI debate classes using smart devices.

This study concentrated on the dining out consumption behaviors, dining out selection attributes, and changes in eating habits of silver generation. Total 216 residents in metropolitan area were employed for statistical analysing. The results are as follows. First, as the result of t-test and ANOVA showed that female and higher academic background tended to regularly take high level of fruits, vegetables, meat, and fish eating habits. These results identified that dining out culture and dietary lifestyle are closely linked. Second, as the result of difference in dining out consumption attitudes on eating habit of silver generation, consumers who have better eating behaviors tended to consider the physical environment, variety of menu, and service quality when they choose a restaurant. Third, as the result of analysis on changes in dining out consumption behavior based on eating behavior of silver consumers, groups differences were found from only the source for information on dining out business and standard variable in selection of dining out business. Fourth, physical environment, variety of menu, business quality, and service were indicated as significant selection attributes of dining out among silver peoples. Fifth, dining out consumption behaviors of silver consumers were developed through newspapers, magazines, and previous visiting experiences. In conclusion, the results of present study showed that silver consumers tend to select a restaurant based on word-of-mouth and various factors related to experiences. Hence, various promotional activities are necessary for the business succession.

We have examined the perception and the knowledge of science-gifted students and general students in middle school level about high technology related to the science. The subjects of the investigation were 113 gifted students belonging to the universities' science-gifted education center in Busan or Ulsan, and 159 general students belonging to 2 middle schools in Busan. The survey was conducted with questionnaires on the perceptions concerning the high technology related to the science and the knowledge of a cellular phone without an antenna, and an LED(Light Emission Diode). The results of this survey concluded that the gifted students were more interested and aware of the high technology than the general students, these results are statistically significant. It has been found that there are significant differences between the gifted students and the general students in terms of the areas they want to learn, the source of information and the preferred learning method in advanced science and technology. Also, the gifted students were recognized to be better than general students in understanding an electromagnetic wave related to a cellular phone without an antenna, and a semiconductor connection with an LED.

A number of studies have been conducted to prevent obesity due to the worldwide increasing rate of obesity and its adverse effects on our health. Recently, a relationship between obesity and gut microbiome has been reported. Fecal and cecal microbiota are generally targeted for examining the gut microbiome during dietary interventions. There is, however, no common understanding on which microbiota and how results elucidated from the data would differ. In this study, we conducted dietary induced obesity study and compared fecal and cecal microbiota affected by dietary interventions. Normal Diet and high fat diet were fed to 6 weeks old mice for 12 weeks, and 16 S rRNA genes amplified from fecal and cecal DNA were sequenced using MiSeq. Our results show that the 𝛼-diversity showed significant differences between the dietary interventions as well as cecal and fecal microbiota. The difference in the taxonomic compositions between cecal and fecal microbiota had become clearer at the family and genus level. At the genus level, Faecalibaculum and Lactobacillus were more abundant in the cecal and fecal microbiota, respectively. In general dietary intervention studies, dietary effects are more significant than type difference. However, the microbiota analysis results should be interpreted carefully, considering both diet and samples (feces/caecum).

This study aims to implement a model for developing participatory labor archives for shipbuilding labor archives in young-do, Busan, and to find possibilities of building digital labor archives as participatory ones. The methodology of locality documentation has been applied, and locality archives accepting participation of people with experiences from shipbuilding industry have been examined. Omeka was applied because it is an open-source software and provides additional functions which support various user participations and web-publishing. Following the the model, firstly, a preliminary investigation was conducted and research of participatory agents and records was proceeded. Secondly, it collected and described information of the agents and records by institutions with records and provenance. Thirdly, it developed archival contents specific to events, persons and workplaces in association with archival information. For the follow-up study, plugins were installed and tested to apply for further experiment with participation.

Corporations report their economical, environmental, social influences and achievements through sustainability reports. Apart from the financial reports, which are subject to legal restrictions, sustainability reports inform non financial achievements of a corporation, thus the reliability of the information is solely dependent on the corporation itself. The current sustainability reports are of types that cannot include proof or source of the index data, thus they are tended to be regarded as means of publicity. The reliability of the reports is often questioned. This research applied the concept of Evidence-Based Accountability, which will allow the confirmation of accountability through records including contents and context of the tasks. Evidence-Based Accountability means producing and accumulating witness records of actions, then managing the records as usable information and use them as accountability information. Index data from sustainability reports of domestic corporations and web based reports of Vodafone was reviewed. Measures to link task records as proof of index data was studied. To make this possible, record production and acquisition system was redesigned in order to secure required records as evidence. Linked build-up of SR system and RMS was proposed. The proposed system will allow collection and management of records as SR accountability information, and provide the data when necessary. Also, corporate infrastructure was proposed. This infrastructure will build a professional records management system in stages, through organizational system and regulations. Cooperation of staff in this infrastructure will support reliable corporate accountability.
