Recently, many advanced countries have used original ICT tools in their educational courses. But Korea didn't have any effective origin ICT tools in our mathematical education, compared with other countries which have developed various tools, for examples, Web-Mathematica and HP Calculator. Although we have the advanced IT environment, the educational environments in mathematics using ICT seems to be not promising. In this paper, we suggest a new mathematics education tools in ICT and the internet environments in Korea, and a teaching and studyingmodel for the teachers, students and classrooms. It is based on the Sage-Math and RPG. Sage-Math which is the software based on the web and RPG(Random Problem Generator) will give a good answer for the future of Korean mathematics ICT education.

Scrub typhus is a fever-related disease that is commonly diagnosed during the autumn season. The number of patients affected by this disease continues to increase every year. However, the cause of the disease and the regional differences of its incidence are poorly understood. This study examined the epidemiological features and regional differences in the incidence of scrub typhus. The monthly incidence of cases from all reports rose to more than 90% during the fall season (October~December). Based on the analysis of the 18,851 cases in the epidemiological investigation, 14,777 (78.4%) and 4,074 (21.6%) cases occurred in high and low occurrence areas, respectively. Moreover, there were more female cases than male cases (males: 7,233 [38.4%]; females: 11,618 [61.6%]; P< 0.001). The clinical symptoms, including fever, chills, myalgia, and eschar of the body, were noted in 16,688 (89.1%), 11,533 (61.2%),11,439 (60.7%), and 6,005 (45.4%) cases, respectively. The incidence rates were higher for Gyeongnam, Jeonam, Jeonbuk, and Chungnam provinces. The areas with a high occurrence of scrub typhus were consistent with the areas experiencing a high distribution of Leptotrombidium scutellare. The incidence of scrub typhus has been rising owing to the increasing population of ticks due to global warming and increased agricultural and outdoor activities. Thus, continuous management of patients and preventive environmental measures are needed to control this disease.

Since 1988, the librarian standards prescribed in the "Enforcement Decree of the Library Act" have not been revised at all and they have many weaknesses and limitations. This study proposed revision of librarian standard and legislation based on legal and application issues. It is desirable to revise the structure of 1988 prospectively and to establish new standards for local representative library. In the case of basic personnel, it is desirable to have three librarians in all public libraries or considering the fact that the library's non-professional work is about 30-40%, it is also necessary to consider a plan consisting of two librarians (professional + para-professional) and one non-professional. The local representative library should apply the librarian standard of the public library serving a community of 300,000 people and establish a standard to add non-librarian equivalent to one-third of librarians. In the case of additional personnel, it is desirable for public libraries to increase one librarian whenever the service target population exceeds 10,000, and the local representative library to increase one librarian whenever the service target population exceeds 100,000. And each library needs to add a other full-time staff equivalent to one-third of the librarian.

The purpose of this study is to investigate the moderating effect of home-based welfare facilities for older adults on the associations between the activities of daily living (ADL) / instrumental activities of daily living (IADL) and the depressive symptoms among Koreans in later life. Multilevel analysis was conducted with Korean Longitudinal Study of Aging 5th data and the public report about welfare facilities from Ministry of Health and Welfare in Korea. Samples were 4,139 older adults over 65 years old. The dependent variable was depressive symptoms, and individual level independent variables were ADL and IADL. The ratio of home-based welfare facilities out of 10,000 older adults in each city and province was the moderator. As a result, the effects of ADL on depressive symptoms vary according to the proportion of elderly welfare facilities out of the old population in the community. In specific, the older adults who live in the place where the elderly welfare facility rate was higher were less affected by ADL. Also, the more IADL people had, the more depressive symptoms they had. However, the interaction effect between IADL and the proportion of home-based welfare facilities was not significant. It suggests that delivering welfare services helping ADL through the home-based welfare facilities may be useful for decreasing depressive symptoms. Moreover, considering the proportion of facilities and older population will be helpful to make the welfare facilities efficiently work.

The aim of this study was to determine the prevalence and incidence and evaluate the current status of dental treatment of Amelogenesis imperfecta (AI) and Dentinogenesis imperfecta (DI) in South Korea. The data was based on National Health Insurance Service (NHIS)-National Sample Cohort Database (2002 - 2015) and Jeonbuk National University (JBNU) Dental Hospital (2011 - 2020). The NHIS data analysis showed prevalence of AI and DI were 11.6 and 2.4 per 100,000 people, respectively. The annual incidence of AI and DI for 2013 - 2015 were 2.2 and 0.5 per 100,000. There were no statistically significant differences regarding the number of visits, the reimbursable cost among AI, DI patients and others. In the patient analysis of the JBNU dental hospital, proportion of the reimbursable and non-reimbursable cost for AI patients were 12.1% and 87.9%, while DI patients accounted for 18.6% and 81.4%.

There has been a lot of research on the real estate market, but a lack of research on the supply and demand of housing supply in each region, reflecting the changes in population growth and supply. It is calculated as the transition probability of the Markov chain model by reflecting the data on the number of houses per 1,000 people in the past 35 years and the forecast data for population change by region, in terms of supply (housing) to demand (population) for factors on the real estate market. According to the calculation results of the real estate market by region, the housing supply to the metropolitan area such as Gyeong-gi, Incheon, and Seoul is expected to be insufficient for a considerable period of time, considering the population changes by region. To stabilize the real estate market, it was confirmed that it was necessary to actively apply the differentiation of housing supply by region. It is meaningful in terms of verifying long term trends in the real estate market by region that reflect the prediction of population change, and it is expected that the methods used in this study will be practical through the analysis results using the historical data.

Objectives : The acupoint-meridian relationship of an acupoint is one of important features of the acupoint. It has also shown evolutionary development over the history of medicine. This study analyzed the prototype kind of information on acupoint-meridian relationships in the A-B Classic of Acupuncture and Moxibustion(the Classic) of 2c BCE. Methods : The acupoint-meridian relationship of all the acupoints listed in the Classic was counted and reviewed in comparison with the information in the contemporary standard texts. Results : In comparison with the contemporary standard of 361 meridian points, the Classic listed 349(97%) acupoints. Of contemporary standard 361 points, 287(81%) acupoints still maintain the same acupoint-meridian relationship as in the Classic. Conclusions : Acupoint-meridian relationship in the Classic has largely been maintained throughout the history and still comprises a major proportion of the contemporary body of knowledge on acupoint-meridian relationship.
