  • Pollen and spores as well as their morphological characteristics are biological stability materials in which contains historical information about vegetation and climate changes. As noted researcher Neishtadt in 1971, the lake and swamp deposits were developed only in Holocene period. The geological history of Darkhad depression which is situated in the Northern end of Mongolia from ancient time become under scientific interest of many researchers. Our investigation was focused on pollen analysis of lake sediment of Darkhad depression which caused bottom of paleolake. In Mongolia the palynology science is beginning to develop since 1990 and in 2000 the laboratory of palynology was established at the department of Biology, State Pedagogical University of Mongolia. Researchers from this laboratory working on pollen morphology of present flora in order to classify plants taxonomy. Another part of our investigation is mellitopalynology, which is studying of pollen grains in a honey. Although, this research has been extending by pollen analysis of sediment and lake deposits in past few years on the basis of high sensitive microscope and modem technology.

  • Globalization and the development of technology have turned creativity into a necessity. Numerous countries consider creativity to be the major model of economic development. In this era of the knowledge-based economy, creativity is becoming a catalyst for the development of millions of people around the world. Irina Bokova, the former Director General of UNESCO, has stated that the cultural and creative industries have a capital of 2 250 billion US dollars, almost 30 million jobs worldwide in the economies of advanced countries and developing countries (Cultural Times, 2015). Copyright is a branch of intellectual property with a wider scope, forasmuch as it applies to every product of literary, scientific and artistic works in all forms of expression, relating to certain levels of originality.

  • We examined the inquiry activities in the material domain of the elementary science textbooks and experimental workbooks based on 2009 revised curriculum. The analysis framework was SEP (Science and Engineering Practices) - 'Asking questions and defining problems', 'developing and using models', 'planning and carrying out investigations', 'analyzing and interpreting data', 'using mathematics and computational thinking', 'constructing explanations and designing solutions', 'engaging in argument from evidence', and 'obtaining, evaluating, and communicating information'. Sub-SEP of each grade band were also used. The results showed that the $3^{rd}{\sim}5^{th}$ grade science textbooks and workbooks mainly emphasized 'make observations and/or measurements', 'represent data in tables and/or various graphical displays', or 'use evidence to construct or support an explanation or design a solution to a problem' among around 40 sub-SEP. In the case of the inquiry activities for $6^{th}$ grade, majority of sub-SEP included were also only 'collect data to produce data to serve as the basis for evidence to answer scientific questions or test design solutions', 'analyze and interpret data to provide evidence for phenomena' or 'construct a scientific explanation based on valid and reliable evidence obtained from sources'. The type of 'asking questions and defining problems', 'using mathematics and computational thinking' or 'obtaining, evaluating, and communicating information' were little found out of 8 SEP. Educational implications were discussed.

  • Many countries such as The Republic of Korea have established their own nutritional standards, collectively termed Nutrient Reference Values (NRVs), and they vary due to the science which was reviewed, the purposes for which they are developed, and issues related to nutrition and food policy in the country. The current effort by the Codex Alimentarius Committee on Nutrition and Foods for Special Dietary Uses (CNFSDU) to update the NRVs that were established following the Helsinki Consultation in 1988 represents an opportunity to develop a set of reference values reflecting current scientific information to be used or adapted by many countries. This paper will focus on possible approaches to selecting or developing reference values which would serve the intended purpose for nutrition labeling to the greatest extent possible. Within the United States, the Food and Drug Administration (U.S. FDA) is currently reviewing regulations on nutrition labeling to better address current health issues, and is expected to enter into a process in the next few months to begin to explore how best to update nutrient Daily Values (DVs), most of which are still based on the Recommended Dietary Allowances (RDAs) of the Food and Nutrition Board, U.S. National Academy of Sciences, last reviewed and revised in 1968. In this presentation, I review the current purposes in the U.S. for nutrition labeling as identified in the 1938 Food, Drug, and Cosmetic Act as amended, the scientific basis for current nutrition labeling regulations in the United States, and the recommendations made by the recent Committee on Use of Dietary Reference Intakes in Nutrition Labeling of the Institute of Medicine (2003) regarding how to use the DRIs in developing new DVs to be used on the label in the United States and Canada. Based on these reviews, I then provide examples of the issues that arise in comparing one approach to another. Much of the discussion focuses on the appropriate role of nutrient labeling within the Nutrition Facts panel, one of the three major public nutrition education tools in the United States (along with MyPyramid and Dietary Guidelines for Americans).

  • This research was planned and executed to evaluate how the composition of Yack-sun tea can affect the health conditions of people who are suffering from diet-related such as being overweight, are obese and have hyperlipidemia, by taking Yack-sun tea in a form of a nutritional supplement with our daily meals. We produced Kangjieum with Lycium chinense Mill., Polygonum multflorum Thunb, Cassia tora L., Crataegus pinnatifida Bge and Salvia miltiorrhiza Bge. Thus, we approach of oriental diet therapy area research of Kangjieum and analysis proximate composition, water soluble antioxidant content. The content(%, dry basis) of total carbohydrate was 60.23%, crude protein was 18.18%, crude ash was 11.36% and crude fat was 10.23% in Kangjieum. Total water soluble antioxidant content was 1.027 ${\mu}g/m{\ell}$ of Kangjieum. We think that scientific and objective evaluation was done on the components of the Kangjieum prescription. This basic data could help guide the application of oriental medicinal resources into other foods and serve as a stepping-stone for use of Kangjieum in the burgeoning field of nutraceutical foods. Last, the scientific effects of oriental medicinal foods developed according to oriental medicinal theory. This theory is believed to be essential for government policy development concerning validation of medicinal effects and assessment, with the aim of fostering systematic development and providing guidance to food development in the interest of national health.

  • Objectives We analyzed the trends of government-funded research on Kampo medicine in Japan to provide advanced evidence to R&D support policy for Korean medicine, and to introduce new research fields and trends to the researchers. Methods We reviewed the researches on Kampo medicine through 'research-er.jp' and 'KAKEN' database which contain R&D status in Japan and scientific research funding project issued by the Japan Ministry of Education, Culture, Sports, Science and Technology. Results Since 1976, government-funded research on Kampo medicine has been continuously announced, and now 533 tasks have been completed or are in progress. The average duration of the study is 2.54 years, but it has been prolonged to 3.52 years in recent years. 4~5 million yen was supported per project for laboratory research, and an average of 44,342 thousand yen was supported per project for specialized laboratory research and clinical research. Conclusions Despite the absence of systematically supporting departments, the researches on Kampo medicine in Japan were qualitatively superior since they focused on providing the scientific basis for clinical application. As competition in the world's traditional medicine market becomes more intense, it is necessary to improve the competitiveness of Korean medicine. Therefore, a keen interest in Korean medicine and active support from the government is needed.

  • The education system is the communication field should be based on the characteristics of communication science and the function of manpower. However, the current education system at the level of college is insufficient and irrational to meet the requirements of the telecommunication field in our country. The main reasons are as follows: 1. Misunderstanding the characteristics of communication science. 2. Indiscretion of the categories of communication manpower due to lack of coordination between academic circles and communication industrial field. Telecommunication function could be performed only by combining the engineering and the suitable operational control. The communication engineering is similar to the electronic engineering, but the former should follow the miscellaneous international protocol and the domestic regulations, being only a means for the telecommunication function. In order to improve the education system of communiation, we aim to identify the principle of communication science, orthodoxy of the education, the categories of communication industrial field and manpower. The present system has been formed on the basis of ignoring the attributes of manpower and historical background of communication science. Therefore, this paper proposes to set up new departmental organizations for educating communication manpower as the following: In addition, this paper proposes a new curriculum model of the above twodept, and we believe that it well turn out more scientific, effective and reasonable education for the communication science. 1. Modification of the present formation, designated Electronic Communication Department. 2. New formation model: A. The best future model such as establishing ad independent telecommunication college which is composed of : Dept. of Radiocommunication Dept. of Telecommunication Enginnering Dept. of Communication Industrial management Dept. of Transmission Engineering Dept. of Telecommunication Law B. An immediately practicable proposal model instead of the existin Dept.. which is composed of the first two Dept. of the above five Dept. In addition, this paper proposes a new curriculum model of the above two dept. and we believe that it will turn out the education for the communication science to be more scientific, effective and reasonable.

  • 이 연구는 위봉사보광명전 백의관음벽화의 보존처리에 앞서 진행되어진 과학적 조사에 관한 결과물로써, 벽체의 입도분포 및 미세구조와 화학성분 그리고 광물 결정상을 분석하였으며, 안료 및 접착매질을 분석하였다. 또한 비파괴진단 방법인 초음파 탐사를 통해 벽화내부에 대한 안정성을 파악하였다. 분석 결과 벽체에 사용된 광물입자들은 중립질 이상의 모래와 세립질 이하 풍화토의 혼합물인 것으로 판단되며, 채색에 사용된 안료는 바탕층은 황토, 백색안료는 호분, 적색계열의 안료는 석간주를 사용하였고 녹색계열은 석록이 사용되었던 것으로 추정된다. 향후 벽화 보존처리에 있어 이와 같은 과학적 분석을 통한 보존처리를 실시한다면, 처리 시 안정성을 높이고 벽화의 보존관리를 위한 기초자료로 활용될 수 있을 것이다.
