  • The ASRP(Ammunition Stockpile Reliability Program) is a overall evaluation system of ammunitions to improve the combat strength, having a short history. The storage lifetime of ammunitions, more than 20 years since being produced, differs according to storage circumstance and period. And it shows the different reliability for munitions. Because most ammunitions in military have been stored for a long time, these ammunitions need to be evaluated to maintain Serviceability, Reliability, Safety and Performance for the use of military. In this paper, it suggested the need to develop the techniques for ourselves, to make more laboratories for surveillance and testing and to extend research funds & concerns.

  • A 6-year-old spayed female Persian cat presented with a 3-month history of recurrent ulcerative keratitis with noticeable opacification and vascularization of the right cornea. The lesion was nonresponsive to topical antibiotics and to nonsteroidal anti-inflammatory drugs. Ophthalmic examination showed signs of ocular discomfort, such as epiphora and blepharospasm, in the right eye. Biomicroscopic examination revealed an irregular, edematous, vascularized mass with pink to white tissue on the entire cornea and mild conjunctivitis. A tentative diagnosis of feline proliferative eosinophilic keratitis (FPEK) was made on the basis of clinical appearance. Cytologic examination of the cornea showed a mixture of numerous eosinophils and mast cells, which confirmed the original diagnosis of FPEK. The cat was treated with a topical antibiotic-corticosteroid combination, cyclosporine ointment, trifluridine eye drops, and oral Llysine. The clinical signs improved remarkably 18 days after the cat was first examined. The short-term use of corticosteroids and long-term use of cyclosporine and an anti-viral agent resolved the lesion without recurrence of the disease for 1 year.

  • Daniel Coit Gilman, the first president of Johns Hopkins University, aspired to build an ideal university focused on the competent faculty and their research. His plan was carried out through opening the first American graduate program, hiring professors with the highest-level research performances, assigning them less teaching burdens, and encouraging them to actively publish professional journals. He introduced Department of Mathematics as an initial model to put his plan into practice, and James Joseph Sylvester, a British mathematician invited as the first mathematics professor to Johns Hopkins University, made it possible in a short time. Their concerted efforts led to building the Department of Mathematics as a professional research institute for research, higher education, and expert training as well as to publishing American Journal of Mathematics.

  • During the 1960-1970s, a group of ceramic conservation scientists and ceramic historians in South Korea came together and established their own disciplines. While the two disciplines share the same ceramics as the subjects of their research, there has been little interaction between the two as their research outputs are articulated in remarkably different languages. This paper aims to address the following questions by using a case study that focuses on the research on white porcelains centered on the project of Gyeonggi Museum and a series of studies conducted by one of the museum's project research teams. First, what are the characteristics of and differences between the explanation styles of the two disciplines that share the same research subjects of ceramics? Second, why has the communication between the two disciplines become difficult? Third, if there can be a trading zone wherein the two disciplines would be able to communicate again, what would be its epistemic conditions? The focus of this paper is the relationship between scientific data and ordinary language, which the two disciplines have shared from their inception. By analyzing the relationship, I first argue that, as the analytical techniques of conservation science have become more developed, conservation science's data have gradually lost its relevance in ceramic history, in spite of a shared common language between them; Second, I argue that by recovering the import of shared language again, the scientific data can be placed in a different practical context, providing novel interpretations that are relevant and often consequential to ceramic history.

  • The goal of this study is to develop a hands-on type polar field trip program to inform the importance of the recent polar research and to contribute to the spread of polar science culture. For this purpose, the direction of program development and field trip course were established based on the current Korea Polar Research Institute tour program and research exhibition facilities analysis. Based on this, a total of 6 types field trip programs were developed, including one basic tour program and one optional experience program for the overall introduction of polar research institutes and polar science fields, and four optional experience programs for each education participant that enables field trips and professional experiential learning activities by polar science field. The developed program was revised and supplemented through a total of two trials, and a field trip program manual was produced, including guidance scripts, experience kits, activity sites, and instructor guides for each field trip. At the end, a follow-up study was proposed based on the significance and research results of the developed program.

  • The aim of this study was to review the history of dental hygiene education in Korea on its $50^{th}$ anniversary in 2015. Internal resources and documents from the Korean Dental Hygienists' Association and other accessible resources were examined to verify the historical facts of dental hygiene education in Korea. From 1965 to 1967, the first class of four dental hygiene students graduated, and the legal basis for dental hygiene as a profession was established, which led to the start of the profession Registered Dental Hygienist in 1971. From 1977 to 1993, 13 higher educational institutions started dental hygiene programs. The Korean Dental Hygienists' Association (1977) and Korean Association of Dental Hygiene College Professors (1987) were established in this period. From 1994 to 2006, the duration of major-intensive course programs in dental hygiene was extended to three from the two years of 1994, and the first bachelor's degree program in dental hygiene started in 2002. In this period, studies on dental hygiene became significantly active owing to vigorous activities by academic societies. The master's degree program in dental hygiene was established in 2007. Academic dental hygiene journals, the Journal of Dental Hygiene Science, and Journal of Korean Academy of Dental Hygiene Education were promoted as the registered journals of the Korean Research Foundation. From 1965 to 2015, dental hygiene education in South Korea expanded both quantitatively and qualitatively and is now ready for further progress in the future.

  • The Dutch colonial government introduced social forestry at the end of the 19th century with a commitment to controlling forest resources in the Dutch East Indies. This program was a response to the rampant deforestation which had resulted in forest degradation and poverty of the population around the forest. This study examined the practice of social forestry in the late colonial period which had not been done much. From a historical perspective, social forestry practices in Indonesia before independence could be explained more comprehensively. This study uses a historical method which includes four stages: heuristic, source criticism, interpretation, and historiography (composing historical stories). Sources of information were explored through studies of archival documents and contemporary artefacts, especially official colonial government reports and contemporary newspapers/magazines. Data from various sources are then compared and tested for validity to obtain data validity. The next stage is to build facts based on data obtained and then interpreted using the social science theories. Finally, compiling a historical (historiographical) story about social forestry during the late colonial period. The results showed that colonial forestry during the colonial period was still limited in terms of area and method, namely in the area of teak forest and involving villagers through the intercropping system. Farmers involved in these activities are called pesanggem who earn income from forest land being rejuvenated. However, the relationship between pesanggem and the forestry service has not been well institutionalized, consequently the pesanggem is often disadvantaged. Including certainty of ownership and ownership of forest land never gained clarity and even became a source of conflict.

  • Dutch mathematician Simon Stevin published De Thiende(The Tenth) in 1583. In that book Stevin suggested new numerical notation which could express all numbers. That new notation was decimal fraction system. In this article I will argue that Stevin invented new decimal fraction system with two main purposes. The explicit purpose was to invent a new system which could be used easily by practical mathematicians. The implicit purpose which cannot be found in De Thiende alone but in his other writings was to break the Aristotelian tradition which separated geometry and arithmetic which dealt continuous magnitude and discrete numbers respectively.

  • PURPOSE: Application of an oscillating program for the lower extremities is an effective training method for increasing muscle strength. However, no oscillatory program has yet been identified to confirm the effectiveness of oscillation for balance ability and maximum muscle strength. We investigated the effects of an 8-week vibration exercise program on the maximum muscle strength and balance of the lower extremities. METHODS: Research subjects participating in the study were 22 male and female college students with no past history of diseases of the nervous or musculoskeletal systems. All subjects were randomly divided into two groups and performed their assigned experimental treatment 3 times a week over a period of 20 min for 8 weeks. Maximum strength of the quadriceps extension, flexion, and balance ability were measured using Biodex System 4 and Biodex balance systems. RESULTS: The 8-week oscillation program resulted in a significant increase in quadriceps extension and flexion strength in both male and female participants (p<.05). The balance ability also showed a significant improvement after the oscillation program (p<.05). The balance value was higher for male 17% than for female 21% (p<.05) participants. CONCLUSION: An 8-week oscillation program led to an increase in the strength of knee flexion and extension. The balance ability also improved significantly. This positive effect on balance ability was higher in female than in male subjects.
