The Chemist Antoine-Laurent Lavoisier and mathematician Pierre Simon Laplace, who conducted a collaborative research on heat phenomena, are two of the key figures that represent French scientific community in the late 18th century. They joined hands together to understand heat phenomena that had not been fully explained until that time. They studied heat phenomena based on a heat particle model called 'caloric' and this study further expanded into light, magnetism and electricity, laying groundwork for many other research achievements afterwards. This article goes through their individual researches and looks into the process of their joint research based on the analysis of their publications. Further to these, it emphasizes its continuity with the Laplacian Program, a large-scale research project conducted in the early 19th century. Lastly, this article presents how science can merge with history, and at the same time, introduces the prerequisites for successful convergence research through existing research cases.

China has a very large area, but the total and average amount of forest resources are always relative scarcity, retrospect the forest history, when the activities of human beings existed on the earth, the forest resources began to reduce gradually, it indicates that the amount of the forest resources have grate connection with the activities of human beings, especially from the foundation of New China, long term out-of- order logging and unsustainable development make the forest resources and ecological environment be destructed seriously. However, although Chinese forest resources still face a large number of complicated problems, it has already begun to recover and been into the right orbit through listing and analysis a series dates. Additionally, six key forest resources program's launching and the strategy shifting will take china enter a bright future.

Submillimeter galaxies (SMGs) have played an important role in the understanding of galaxy evolution and cosmic star formation history at high redshift because they are known as being located at z ~ 2 and harbor a vigorous star formation. Therefore studying properties of SMGs can lead us to understand evolution of massive and actively star forming galaxies and distribution of cosmic star formation density. Recently we detected 548 SMGs near North Ecliptic Pole with JCMT/SCUBA-2 from the JCMT large program covering about 2 deg2 so far. To derive their physical parameters, we compiled a multi-wavelength photometry ranging from optical (0.3 ㎛) to submillimeter (850 ㎛) by cross-identifying counterparts at different wavelengths. In order to find counterparts, we used either VLA-1.4 GHz image and/or Spitzer/IRAC 3.6 ㎛, 4.5 ㎛ image. The number of SMGs with relatively robust counterparts is 349. In this talk, we present photometric redshifts, stellar mass, star formation rates, total infrared luminosity, and AGN fraction of these 349 SMGs derived through SED fitting analysis.

Objectives: The current study reviews the implementation and evaluation of the Chronic Disease Self-Management Program (CDSMP) in the United States (U.S.) to illustrate the program's potential contribution to improving health among Korean adults with chronic conditions while saving healthcare costs. Methods: This study examines existing literature on the history, theoretical background, essential elements, and delivery outcomes of CDSMP with special focus on the successes and challenges to be faced in the implementation of CDSMP to Koreans with chronic conditions. Results: CDSMP is designed to empower people with chronic conditions to develop skills necessary for medical, social role, and emotional management of chronic conditions. Recent studies show the utility of CDSMP in achieving the Triple Aim health reform goals (i.e., better care, better health, better value). Lessons learned from the U.S. experience emphasize the importance of establishing evidence-based studies, collaborating with community partners, and diversifying funding sources to make CDSMP more sustainable. Conclusion: The current study demonstrates the replicability of CDSMP and potential for expansion in Korea. More concerted efforts among academia, government, and communities are needed to deliver CDSMP to Korean adults and identify its effectiveness within the Korean context in terms of meeting the Triple Aim goals of better care, better health, and better value.

A 14 kg, 9-year-old, spayed female, Cocker Spaniel was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of head tilt and circling. Otitis externa and media were diagnosed by computerized tomography, and total ear canal ablation was performed. In preanesthetic evaluation, systemic hypertension and second-degree atrioventricular block were observed, but there was no regurgitation through the heart valves. Systemic hypertension was managed with amlodipine (0.1 mg/kg, PO, BID) for the anesthesia. The dog was premedicated with cefazolin (22 mg/kg, IV) and midazolam (0.2 mg/kg, IV). Anesthesia was induced with alfaxalone (2 mg/kg, IV) and maintained with isoflurane and 100% oxygen following intubation. During surgery, vital signs (heart rate, respiratory rate, blood pressure, end tidal carbon dioxide partial pressure and body temperature) were maintained within normal ranges, but bradycardia was observed and corrected with glycopyrrolate (5 ug/kg IV, twice). During subcuticular suture, electrohemostasis was applied at the incision line, which was close to the trigeminal nerve. In no time at all, heart rate dramatically decreased from 110 to 60 beats per minute. No additional treatment was done because mean blood pressure was maintained above 70 mmHg. The heart rate recovered according to the decrease of end tidal isoflurane concentration and there were no complications associated with the anesthesia and surgery. Sudden bradycardia after electrical stimulation around the trigeminal nerve was considered as trigeminocardiac reflex (TCR). It is recommended to be careful of bradycardia from TCR when electrocautery is used in the craniofacial area during surgery.

The secondary science teachers' professional needs and their preference for training method between off-line and on-line education were investigated. A nation-wide survey was administered to 145 science teachers from 106 secondary schools. The respondents showed high demands on all items. The prominent need was to motivate students learning science. To the contrary. their need for learning more about history and philosophy of science was the lowest. Veteran teachers and high school teachers had higher demands on designing evaluation items, but nonveteran teachers on evaluating the effectiveness of their instruction and updating their scientific knowledge. Teachers preferred the online education as a training method for most items except laboratory activities.

Despite the importance of mathematics education, many students in high school have lost their interests and felt difficulties and they don't have 'mathematical' experience with meanings attached because of the entrance examination. This paper attempted to resolve these problems and find the teaching-method with which students can study by themselves with more confidence. Nowadays students' use of Internet is very popular. After develop 'the development of mathematical power' program based on mathematics history, history, science, the application of problems in real world, and self-evaluation, I made students repeat them after making teaching lessons in classroom as moving pictures. Through this processes, I attempted to develop the Self-Directed Learning' ability by making public education substantial. First of all I analyzed the actual conditions on 'Self-Directed Learning' ability in mathematics subject, the conditions of seeing and hearing in Internet learning program, and students' and their parents' interests in Internet education. By analyzing the records, I observed the significance of the introducing mathematics history in mathematics subject in early stager, cooperative-learning, leveled-learning, self-directed learning, and Internet learning. Actually in aspect of applying 'the development of mathematical power' program, at first I made up the educational conditions to fix the program, collected the teaching materials, established the system of teaching-learning model, developed materials for the learning applying Internet mail and instruments of classroom, and carried out instruction to establish and practice mathematics learning plan. Then I applied the teaching-learning model of leveled cooperation and presentation loaming and at the same time constructed and used the leveled learning materials of complementary, average, and advanced process and instructed to watch teaching moving pictures through Internet mail and in the classroom. After that I observed how effective this program was through the interest arid attitude toward mathematics subject, learning accomplishment, and the change of self-directed learning. Finally, I wrote the conclusion and suggestion on the preparation of conditions fur the students' voluntary participation in mathematics learning and the project and application on 'the development of mathematical power' program and repeated learning with the materials of moving pictures in classroom.

Augustus De Morgan became to be deeply interested in the education of pure mathematics since he came to teach in UCL because of the specific nature of natural philosophy lectures, the academical knowledge and reasoning powers of the students, and the negative attitudes of London society on mathematics. During his long tenure, he really tried his best to make his students understand the important concepts and the principles of pure mathematics, and logically explain the processes of inducing and proving the laws of pure mathematics. When he could not stay as a mere researcher, he had to concern himself with and pay attention to the problems of educating students. And then his teaching style was constructed in a specific way by the various attitudes about mathematics, the boundary relationship between the adjacent academical branches, and the social and systematic nature of UCL.

In order to shed some light on the historical change of biodiversity concepts, this paper reviews the science and technology studies (STS) literature on the history of biological research on human genetic diversity. By doing that, I show how the notion of genetic diversity in the human population - from "race" to "population" to "biogeographical ancestry" - has changed with methodologies and techniques over the last hundred years. In the meantime, I point out contexts and situations, despite conceptual and methodological developments, that show that current human genetic diversity research is slipping into the past mistakes of scientific racism. This article offers biodiversity researchers an opportunity to consider their own scientific practices on classifying species more reflectively.

The purpose of this study is to develop the education programs for the archival librarian in Korea. The importance of archival work requires that archivists should receive an archival education at university. But there is no professional education programs in Korea. The interdisciplinary character of archival studies programs make it possible to place them in a variety of setting, such as a department of library and information science, department of history. Currently, archival education must assume a much more prominent role within the library and information science. Library and information science educators, increasingly concerned with their own survival, seek rational ways to diversify their area. They are looking at mergers with allied fields. Archival education programs will find a welcome home in a number of existing department of library and information science. Archival education programs could be provided according to three categories undergraduate coursework, master of archival studies, and continuing education programs. The body of knowledge that a student should master as part of an archival education program is classified here as basic knowledge of archival studies, specified knowledge of archives and records, practical knowledge of archives and records management, and complementary and contextual knowledge of archival studies.
