This study aims to investigate how pre-service elementary school teachers understand 'something scientific', 'being scientific', 'scientific events' and 'scientific questions' through semantic network analysis. To achieve this purpose, this study carried out a central analysis of the frequency and density of words and the degree of connection between key words, a concentric analysis, a click analysis and a common network analysis through text semantic network analysis by using NetMiner 4.0 Program. Based on the results of these analyses, this study came to the following conclusions. Firstly, in perceiving 'something scientific', pre-service elementary school teachers recognized 'verification', 'objective' and 'experiment' as most important words. In other words, they perceived that main grounds for something scientific should be provided through clear facts, possible to be verified and accompanied by an exact and logical theoretical system. In regard to 'being scientific', they perceived 'explanation', 'objective' and 'verification' as most important words, while having a traditional point of view that science is a set that can be explained objectively. Secondly, in regard that the term, 'observation', is contained in 'scientific events', they showed a high rate of understanding it as a scientific event. In regard to scientifical reasons, they showed the highest frequency of 'observation', and for unscientific reasons, they showed the highest frequency of 'behavior'. In perceiving 'scientific questions', they showed the highest frequency of determining bacteria-related questions as scientific. As a reason why they thought as scientific, they mentioned 'observation' most frequently like 'scientific events', while mentioning 'value judgement' as a reason why they thought as unscientific most frequently. From the results of integrated network analysis, this study found out that words pre-service teachers commonly used in stating scientific events or scientific questions were overlapped with words they mentioned for scientific events or scientific questions. As a result, it was found there were many pre-service teachers having interpreted scientific words without clearly distinguishing scientific events or scientific questions.

Just after decolonization in 1945, there was no basic research in Korea representing only 12 PhD's and about 300 college graduates of science and technology areas. Now, the symbols of basic scientific research have been developed to 66,000 university researchers in science and technology area and 36,000 SCI papers. The government can be credited as playing the most important role in such development, but there are no studies about what are the process and details of the policies. 1his paper examines the flow of major events in the basic scientific research through government policies suggesting a chronological table. The selection and checking of each event were supported by two other experts besides two authors. We divide policies for basic scientific research with policy infrastructure, administration system, and policy subject. Policy subject is further divided into research environment, research infrastructure, and human resources. The results are threefold. We show that basic scientific research has progressed over 5 stages of development, and 15 significant incidents has occurred. Also, major events were done not solely by the government, but also the requests by researchers. Scientific society has continually put the impetus on the government.

In this study, the influences of the context of discrepant events on the conceptual change process using cognitive conflict strategy were investigated in terms of students' cognitive and motivational variables such as cognitive conflict, situational interest, attention, effort, conceptual understanding. A preconception test was administered to 536 seventh graders. A test of response to a discrepant event and a situational interest questionnaire were then administered. The context of discrepant events, either scientific or everyday, was randomly presented to the subjects. After learning the concept of density, the tests of attention, effort, and conceptual understanding were administered. The reponses of 194 students who had been found to possess the target misconception were analyzed. The results revealed that the scientific-context discrepant event induced higher cognitive conflict than everyday-context one. The context of discrepant events, however, did not show significant correlations with situational interest, attention, effort, and/or conceptual understanding. The result of path analysis indicated that the context of discrepant events both directly influenced cognitive conflict and indirectly influenced conceptual understanding via cognitive conflict.

This paper starts with the assumption that in order for the popularization of hanbok leading to greater interest among the public for Hanbok and its uses in everyday life, the period for Hanbok events each year must be solidified, making it a standardized provide opportunities for participation regardless of demographic. Globalization of Hanbok most occur through a combination of related academic fields, division of roles in fields of expertise, and a scientific understanding of Hanbok. Thus various Hanbok-related programs such as contests, fashion shows, experience centers and exhibitions should be provided in one unified setting. Government sponsored Hanbok cultural events have generally been aimed at foreigners or foreign human residency, while events in Korea hae generally been carried out by a more diverse rage of groups, making it difficult for the general population to obtain information or participate actively. In order for hanbok to maintain its tradition as the national costume of Korea, Long-term develop plans must be set. Along with popularization in order to bring hanbok into everyday life, methods for the globalization of hanbok must be explored, providing opportunities to spotlight the diversity and characteristics of Korean costumes, in various events which promote participation, festival-forming and globalization of hanbok culture considering elements such as time (yearly, monthly etc.) and audience (age group, social level etc.).

Chloral hydrate is the oldest and most common sedative drug used in moderate sedation for pediatric dental patients. Hence, the purpose of this article is to review the safety and possible adverse events of this drug when used for pediatric dental treatment. A bibliographic search in PubMed, MEDLINE, Cochrane Library and KMbase, KISS, DBpia, KoreaMed, and RISS databases was performed. Using the keywords "dental sedation," "chloral hydrate," and "children or adolescent," 512 scientific articles were found. Subsequently, 183 studies were individually assessed for their suitability for inclusion in this literature review. Altogether, 24 studies were selected. They included 12 cases of death before, during, or after chloral hydrate sedation for dental treatment, majorly due to dosing error and use of multiple sedatives. Additionally, intraoperative adverse events were mostly respiratory problems such as hypoxia and apnea, but most events were temporary. After treatment, prolonged sedation, including excessive sleep and less activity were the most common postoperative adverse events, and even death cases were reported. Despite the wide acceptance of chloral hydrate as a sedative-hypnotic agent, the risk of adverse events and adequate dose should be of great concern when using it for pediatric dental sedation.

This study aims to predict uncertain future scenarios that may unfold in South Korea in the near future, utilizing the theory of extreme events(X-events). A group of 32 experts, consisting of government emergency planning officers, was selected as the focus group to achieve this objective. Using the Focus Group Interview (FGI) technique, opinions were gathered from this focus group regarding potential X-events that may occur within the advanced science and technology domains over the next 10 years. The analysis of these opinions revealed that government emergency planning officers regarded the "Obsolescence of current technology and systems," particularly in the context of cyber network paralysis as the most plausible X-event within science and technology. They also put forth challenging and intricate opinions, including the emergence of new weapon systems and ethical concerns associated with artificial intelligence (AI). Given that X-events are more likely to emerge in unanticipated areas rather than those that are widely predicted, the results obtained from this study carry significant importance. However, it's important to note that this study is grounded in a limited group of experts, highlighting the necessity for subsequent research involving a more extensive group of experts. This research seeks to stimulate studies on extreme events at a national level and contribute to the preparation for future X-event predictions and strategies for addressing them.

The MERIS MCI (Maximum Chlorophyll Index), measuring the radiance peak at 709 nm in water-leaving radiance, indicates the presence of a high surface concentration of chlorophyll ${\underline{a}}$ against a scattering background. The index is high in 'red tide' conditions (intense, visible, surface, plankton blooms), and is also raised when aquatic vegetation is present. A bloom search based on MCI has resulted in detection of a variety of events in Canadian, Antarctic and other waters round the world, as well as detection of extensive areas of pelagic vegetation (Sargassum spp.), previously unreported in the scientific literature. Since June 1 2006, global MCI composite images, at a spatial resolution of 5 km, are being produced daily from all MERIS (daylight) passes of Reduced Resolution (RR) data. The global composites significantly increase the area now being searched for events, though the reduced spatial resolution may cause smaller events to be missed. This paper describes the composites and gives examples of plankton bloom events that they have detected. It also shows how the composites show the effect of the South Atlantic Anomaly, where cosmic rays affect the MERIS instrument.

Objective: This study is to review three representative psychological perspectives that explain scientific construct of emotion, that are the discrete emotion model, appraisal model, and dimensional model. Background: To develop emotion sensitive interface is the fusion area of emotion and scientific technology, it is necessary to have a balanced mixture of both the scientific theory of emotion and practical engineering technology. Extensional theories of the emotional structure can provide engineers with relevant knowledge in functional application of the systems. Method: To achieve this purpose, firstly, literature review on the basic emotion model and the circuit model of discrete emotion model as well as representative theories was done. Secondly, review on the classical and modern theories of the appraisal model emphasizing cognitive appraisal in emotion provoking events was conducted. Lastly, a review on dimensional theories describing emotion by dimensions and representative theories was conducted. Results: The paper compared the three models based on the prime points of the each model. In addition, this paper also made a comment on a need for a comprehensive model an alternative to each model, which is componential model by Scherer(2001) describing numerous emotional aspects. Conclusion: However, this review suggests a need for an evolved comprehensive model taking consideration of social context effect and discrete neural circuit while pinpointing the limitation of componential model. Application: Insight obtained by extensive scientific research in human emotion can be valuable in development of emotion sensitive interface and emotion recognition technology.

This paper reports on a way of using cognitive conflict in order to bring about conceptual changes. Cognitive conflict occurs when there is a discrepancy in students mind between everyday events and the scientific concepts which are used to explain these events. In order to overcome this conflict auxiliary scientific hypotheses can be introduced, which makes the resolution easier. In this paper, we suggest a new model of conceptual change and a model of instruction named 'structured contrastive activity' which consists of three stages: contrastive discussion by introducing the auxiliary hypotheses for clarifying the cognitive conflicts of students, observing the phenomena in idealised contexts in order to increase the status of the scientific concepts, laboratory experiments which bridge the two contexts.

These days, advanced technologies provide an easy way for the public to obtain information about anything, including astronomy. Most people know astronomy for its sky events and scientific results. In Indonesia, the public has a high interest not only in astronomy information but also in participating in astronomy events, but it is limited to those who has access to a club nearby. Otherwise, for those who live in remote areas or simply don't have any access, they depend on information from newspapers, magazines, books or word of mouth. They usually think that astronomy is a difficult subject to learn, while in fact it is something doable and fun.
