The purpose of this study is to observe the effect of Cordyceps Militaris(CM) complex extract treatment on patients diagnosed with rheumatoid arthritis(RA). We reviewed medical records of 9 rheumatoid arthritis patients who visited the pain & rehabilitation center, Daejeon Korean Medicine Hospital of Daejeon University and were treated with CM complex extract from October 14, 2019 to October 14, 2020. We analyzed the records of DAS 28(Disease Activity Score 28), CDAI(Clinical Disease Activity Index), SDAI(Simplified Disease Activity Index), VAS(Visual analogue Scale), and KHAQ-D(Korean Health Assesment Questionnaire-Disability Index) before and after treatment to evaluate the effects of CM complex extract on RA. As a result, the scores of DAS 28(p<0.05), CDAI(p<0.01), SDAI(p<0.01) and VAS(p<0.01) were statistically significantly decreased, after 8 weeks of taking CM complex extract in RA patients. In conclusion, CM complex extract treatment may have potential effects of reducing disease activity and pain and improving quality of life in patients diagnosed with RA.

Purpose: This study aimed to identify the activities of daily living of the elderly in day and night care facilities and the nursing needs of the elderly and caregivers. Methods: The subjects of this study were 90 elderly people and their caregivers, who lived in B and G cities used day and night care facilities. The collected data were analyzed using frequency analysis, descriptive statistics, independent t-test, and Pearson's correlation coefficient using the SPSS 25.0 program. Results: Caregivers have a higher awareness of nursing needs than the elderly. Both the elderly and their caregivers had the highest informational nursing requirements. There was a positive correlation between the activities of daily living of the elderly and physical nursing needs of caregivers, and there was also a positive correlation among the nursing needs in each area. Conclusion: These results suggest that day and night care facilities should provide customized nursing services by assessing the activities of daily living of the elderly and the nursing needs of the elderly and caregivers by area before establishing a nursing plan. This will enable them to provide effective nursing services for elderly people. In addition, we propose research to develop a nursing information program for the elderly and caregivers.

This study was implemented to verify the validity and effectiveness of the current evaluation indicators by analyzing the content and result of the current survey for evaluating a small library, based on the achievement rate of each index. To this end, questions, included in evaluation indices for the small library were reviewed, and survey data from a total of 19,476 libraries during the past 3 years from 2018 to 2020 were investigated to analyze the evaluation scores, differences and achievement rates of each item. It was proposed to delete or add some indicators of the current evaluation category, and to raise supplementally the need for qualitative assesment. Based on the research results, the following implications are suggested. First of all, the evaluation of small libraries should focus on the quality of the services they provide rather than the library environment. Second, demonstrable systematic indicators should be designed and then clearly explained to resolve the ambiguity of the terms used. Third, for better analysis, it is necessary to distinguish evaluation items between public and private small libraries and the assessment process should be done by the local government. Lastly, qualitative evaluation items that can measure users' satisfaction should be added.

Information and Information processing systems must maintain a certain level of security during the total life cycle of Information. To maintain a certain level of security, security management processes are applied to software, automobile development, and the U.S. federal government information system over a life cycle, but theme of no similar security management process in Korea. This paper proposes a Korean-style security risk management framework to maintain a certain level of security in the total life cycle of information and information processing system in the defense sector. By applied to the defense field, we intend to present the direction of defense security work in the future and induce an shift in security paradigm.

Recently, as digital transformation due to the COVID-19 pandemic accelerates, data to improve individual quality of life is being used in large quantities, and more reinforced non-identification processing procedures are required to utilize the most valuable personal information among data. In Korea, procedures for de-identification measures are presented through amendments to laws and guidelines, but there is no methodology to measure the level of de-identification in the field due to ambiguous processing standards and subjective risk measurement methods. This paper compares and analyzes the current status of policy and guidelines related to de-identification measures proposed at home and abroad to derive complementary points, suggests a data context-based risk measurement method centered on pseudonymized information processing, and verifies its validity. As a result of verification through Delphi survey and focus group interview (FGI), it was confirmed that the need for the proposed methodology and the validity of the indicators were high.

Recently, constructing the database of road network is a main key in various social operation as like the transportation, management, security, disaster assesment, and the city plan in our life. However it need high expenses for constructing the data, and relies on many people for finishing the tasks. This study proposed the classification method for discriminating between the road and building points using the entropy theory, then detects the classes as a expecting road from the classified point group using the standard reflectance intensity of road and the characteristics restricted by raw. Hence the main object of this study is to develop a method which can detect the road in urban area using only the LiDAR data.

As we learned in Daegu subway fire accident, fire in the railway tunnel is prone to develop to large disaster due to the limitation of smoke control and smoke exhaust. In railway tunnel, in order to ensure fire safety, fire prevention and fighting systems are installed by quantitative risk assessment results. Therefore, in this research, developed the program to establish quantitative risk assessment and suggested quantitative safety assessment method including fire scenarios in railway tunnel, fire and evacuation analysis model, fatality estimate model and societal risk criteria. Moreover, this method applys to plan preventing disaster for Honam high speed railway tunnel. As results, we presented the proper distance of escape route and societal risk criteria.

It is so sensitive that the wetland ecosystem very weak in artificial interference and environment change. wetlands are a transitional zone between aquatic and terrestrial ecosystems. This natural property is important to people and life. It is necessary to preservation and protection of the wetland with a countermeasure. we really need to Environment-GIS (E-GIS) and digital map which is included correct position, attribute data and range of the wetland. In this study, we take priority of making a database of wetland management. Moreover, we standardize a digital map production of wetland in our research and we improve accuracy of control survey using GPS surveying. The main purpose of this study is to suggest a pre-estimated wetland that have not yet been discovered. by analysing terrain, geological feature, a geographical distribution of plants and animals using GIS.

This study presents the seismic risk assesment for an extradosed bridge with seismic isolators of lead rubber bearings(LRB). First, the seismic vulnerability of a structure and then the seismic hazard of the site are evaluated using earthquake data set and seismic hazard map in Korea, and then the seismic risk of the structure is assessed. The nonlinear seismic analyses are carried out to consider plastic hinges of bridge columns and nonlinear characteristics of soil foundation. The ductility demand is adopted to describe the nonlinear behavior of a column, and the moment-curvature curve of a column is assumed to be bilinear hysterestic. The fragility curves are represented as a log-normal distribution function for column damage, movement of superstructure, and cable yielding. And seismic hazard is estimated using the available seismic hazard maps. The results show that the effectiveness of the seismic isolators for the columns is more noticeable than those for cables and girders, in seismic isolated extradosed bridges under earthquakes.

Objectives: This study aimed to compare the nutritional risk, health status and depression levels of young-old (65-74 years) and old-old (75-84 years) women on low-income. Methods: A total of 624 elderly women, each over 65 years of age, participated in this study under the auspices of a community social center. Data were collected from June to August 2011 by means of personal interviews which employed questionnaires. The research tools used in this study were the nutritional risk measuring Mini Nutritional Assesment (MNA) by Kim (2000), perceived health status developed by Lawton et al. (1982), Elderly Depression Criterion developed by Sheikh & Yesavage (1985). The collected data were analyzed using the SPSS WIN 12.0 Program. Results: Nutritional risk, perceived health status and depression levels showed a significant difference between young-old and old-old. There was a positive correlation between nutritional risk and depression and a negative correlation between nutritional risk and perceived health status. A 38.2% variance in depression levels of young-old and a 29.7% variance in depression levels of old-old were explained by perceived health status, nutritional risk and the number of people living together. Conclusion: The findings demonstrate variances in depression levels among low - income women differing in age. As a result, the outcomes of this study ought to be employed in the development of future programs aimed at promoting the health of elderly women.
