이 연구의 목적은 고등학생들의 2015 개정 과학과 교육과정 진로선택 교과목인 '과학사' 과목과 과학과 역사의 관계에 대한 인식을 탐색하는 것이다. 또한 이 연구는 실제 과학사 수업을 경험하기 이전과 이후의 이 인식의 변화를 계열별로 비교하였다. 이를 위하여 고등학생 265명이 그린 과학사와 과학, 역사와의 관계를 표현한 벤다이어그램 도형 자료를 수집하고, 이에 대한 설명 텍스트를 수집하였다. 수집된 자료들은 귀납적으로 범주화하여 최종적으로 범주화하였다. 벤다이어그램 자료를 분석한 결과 '과학과 역사의 만남으로서의 과학사', '독립영역으로서의 과학사', '역사의 일부로서의 과학사', '과학의 일부로서의 과학사', '모두를 아우르는 과학사'의 5가지의 다양한 관계범주 유형을 발견할 수 있었다. 또한 각 유형들마다 다양한 세부유형들이 존재함을 확인할 수 있었다. 또한 과학사 수업 경험 이전에는 많은 학생들이 과학사를 과학 과목과 역사 과목의 교집합으로 여기는 경향을 보였다. 그러나 과목 경험 후에는 인문계 학생들과 자연계 학생들의 관계인식변화는 서로 달라졌다. 인문계 학생들의 경우에는 과학사 과목이 역사과목의 일종이라고 여기는 인식이 더 증가했고, 자연계 학생들의 경우는 과학의 일종이라고 여기는 인식이 더 증가했다. 이와 같은 연구 결과를 토대로 과학사 교육이 기존에 자신이 속한 계열 내에서 익숙하게 배우는 기존의 교과들과는 다른 새로운 관점을 경험할 수 있는 과학사 교수-학습이 실현되어야 할 것임을 제언하였다.

The purpose of this study is to investigate the possibility of introducing the history of science in modern Korea into elementary education. Although there are many studies on applying a history of science to science education, they do not pay attention to the history of science in modern Korea. I survey research papers on the history of science in modern Korea and science education based on a history of science, and elementary science textbooks in Korea, Japan and the US. When we apply the history of science in modern Korea into elementary education, elementary students will recognize science has close relations to Korean culture and history and they will develop the familiarity with science. I show there are 3 ways using the history of science in modern Korea in elementary education: 1) Applying Korean scientists' research contents to science education, 2) Measures to evaluate Korean scientists correctly, 3) Materials for science education programs for gifted elementary students.

Science has developed along with human society and history. In today's society ruled by pluralism, an educational approach using the historical materials which represent their own cultures will make science education more effective. The purpose of this study was to search for the meaning of science education related with a history of science, and to suggest the possibility for science education based on Korean history of science. The conclusions of this study is below: (1) The history of science is useful to teaching science in K-12 setting. That is because it was helpful to make a scientific concept and to invite student's interest about learning science. Moreover, it was most suitable to teach the nature of science as well as the relation between science and society. (2) A model which consists of 15 types of science education materials using Korean history was suggested. This model plays a potential role as a R&D framework of developing teaching & learning materials based on the history of Korean Science.

Hypertension is associated with cardiovascular disease. The environmental and genetic factors can cause the development of hypertension. In this study, the relationship between hypertension and family history of hypertension in Koreans was analyzed in consideration of serum fasting blood glucose levels and age. The study subjects were 2,484 subjects who had a medical examination at a university hospital. The main statistical analysis method was multiple logistic regression analysis. Hypertension prevalence was 16.4% of all subjects, and subjects with a family history of hypertension were 23.5%. The risk of hypertension was 2.36 times higher in subjects with a family history of hypertension than subjects without a family history of hypertension. In addition, in the subjects with fasting blood glucose levels more than 120 mg/dL, the risk of hypertension was 4.44 times higher in subjects with a family history of hypertension compared with subjects without a family history of hypertension. The relationship between family history and hypertension was slightly higher in the older group than in the younger group. To assess the association between hypertension and family history, further cohort study is necessary in the future.

History will be defined as a science on human beings in both space and time(des hommes dans le temps et l'espace). Navigational History is a premise to compose Maritime History. Maritime History is a branch of General History which is classified on the basis of space and will be definded as a branch of history to examine 'inter-realtions between maritime affairs and inland affairs'. Then, what kind of 'go by sea'can be a subject of Navigational History ? A research-subject of Navigational History must be navigation rather than sail or voyage. Because while 'sail' means to 'passive and noncommercial sailing' and voyage means to journeyin a general sense that includes sail and navigation, navigation means to indicate ' to go from one place to another in a ship' adn 'to convoy goods by water'. Then, how can we define Navigation History? Navigational History in a narrow sense is to be a field of studying 'process of development of nautical science and seamanship on the side of History ofScience and Techique, whereas Navigational History in a broad sense is to be a field of analyzing 'effects of historical navigation upon history on the side of General History. On studying Navigational History in a narrow sense, there are signifiacances of disclosing what the development of nautical instruments and arts of navigation have played a role in history. Navigational History in a broad sense is a branch of General History to study effects of historical navigation upon history. In conclusion, the significance of studying Navigation History is to disclose process of developmentof arts of navigation, and on the basis of this study is to reveal how the human elements operate in historical navigation. In short, it should not cease to study Navigational History in a narrow sense, and should enlarge its perspective of research toward Navigational History in a broad sense.

The aim of the research is to focus on the cognitive principles and to achieve human-level intelligence in referring context based browser history and the Windows history. One of the major problems faced by today's computer users is insufficient and single exclusive context based reference of the browser history and the Windows history. Today we search for the browser history and Windows history in different places even though the context is the same. For e.g., When working on a research paper or preparing a business presentation, a user may require to refer many web sites on the internet and various documents on the local computer. The browser can provide only time based history. The windows document history is also time based and limited to list only few documents. Hence, we propose a tool "Cognitive Based Context Aware Reference History Management Tool" which helps to access the exclusive reference of context and time based history in one place. The tool also proposes to store image history with urls and classifies images of a specific topic accessed in different time, bookmarks management and cross browser history management. These features are very useful as we can access all related documents (doc, docx, ppt, pptx, pdf, txt, and html), web pages, images and bookmarks in one place. The tool uses the cognitive principles like classification and association to achieve the purpose.

Background: A comprehensive history taking at the first visit could be an important start of treatment. This study investigated the current status of the initial history taking for dental patients in S area, and the implementation and importance of the initial history taking process. Based on this, we intend to provide basic data for the development of organized and standardized questionnaires in dental clinics. Methods: In April 2019, 303 dental clinics in S area were targeted and special dental clinics (orthodontics, children, and disabled) were excluded. The questionnaire consisted of 29 items, including general characteristics, systemic disease history, dental history, oral health behaviors, and the data were obtained through self-administered questionnaire. Results: Initial history taking was mostly implemented using oral and questionnaire at the time of the first visit. Systemic disease history, dental history, and oral health behaviors differed in the work experience of the dental clinic staff. As a result of analyzing the importance according to implementation, there were significant differences in all questions except drug-related items. The importance of the questionnaire was highly recognized, but the reason it was not actually implemented was because of existing the questionnaire in the clinic and lack of time. Conclusion: Considering that the initial history taking implementation rate showed low, it is necessary to develop standardize a practical questionnaire and interview skills for dental clinics in the future. In addition, training programs should be provided to dental staff that can recognize the importance of initial history taking questionnaires and contribute to active implementation.

The purpose of this study was to investigate the effects of a teaching-learning program using the history of science on elementary school students' academic achievement, science attitude, and science process skill. Subjects were 72 students of two groups in the 5th Grade. A experimental group of 36 was instructed 10 lessons in unit of 'our body' using the history of science. The history of science materials used in this program included 4 explicit method, which are Eii, Eij, Eik and Ea type, and 1 implicit method which is I type. The contents validity of this program was reviewed by the science education specialists. The results of the study were as follows: Students of experimental group showed statistically more significant increase in academic achievement and science attitude than control group students. However, there was no significant difference on science process skill between the instruction by applying a teaching-learning program using the history of science and the traditional instruction. Since this program using the history of science is effective for the attitude improvement of elementary school students as well as academic achievement, it is highly likely to be used as the science education material for students with the low affective area.
