  • Purpose : The purpose of this study is to determine the effect of the overseas volunteer activities of university students on changes in global citizenship. Methods : This study was conducted as a one-group pre-posttest design. The study's subjects were students who participated in the 37th World Friends Korea Youth Volunteer Corps in 2018. Among them, 158 students who completed the survey were included in the analysis. The tool for measuring global citizenship was comprised of knowledge, skill, attitude, and willingness to practice. The data were analyzed using the SPSS 26.0 program, and the statistical significance was set to p<.05. Results : Among the study's participants, there were 123 females (77.85 %). By grade, there were the most juniors, with 68 (43.04 %). There were 53 (33.55 %) seniors, 28 (18.35 %) sophomores, and eight freshmen (5.06 %). Among all participants, 52.53 % had experience in global citizenship education, and 63.92 % had experience in activities related to global citizenship. Because of analyzing the changes in global citizenship before and after overseas volunteer activities, "skill" increased the most, from 3.51±.65 points to 4.34±.56 points (p< .001). Due to analyzing changes in global citizenship before and after overseas volunteerism, the knowledge and attitude of freshmen were statistically significantly positive, with 1.17± 1.23 (p=.011) and 1.41±1.22 (p=.008), respectively. Participants with global citizenship experience had a significant change in attitude (p=.018). Conclusion : It was confirmed that the overseas volunteer activities of undergraduate students in the university brought a positive change to global citizenship. Providing opportunities for global citizenship education and activities in elementary, middle, and high schools in the future will maximize the effects of overseas volunteer activities to improve global citizenship.

  • Many Korean schools are in danger of closure because of a decreasing school-age population, and cases of consolidation of educational institutions in the local community are on the rise. A number of educational records, particularly educational administrative artifacts (hereafter "Edu Artifacts"), are accordingly in danger of disappearing. Despite their historical, cultural, and educational value, systematic management is far from satisfactory. This study thus examines the characteristics of Edu Artifacts from the archival and cultural heritage perspectives and compares standard records management system, special type records management system, and historical manuscripts management system, which are currently used in public institutions, to see what is required to manage them effectively. By analyzing the Edu Artifacts possession status and management system of J University of Education, This study intends to verify the research outcome's effectiveness by presenting the essential functions of the management system of Edu Artifacts and the corresponding menu structure.

  • This study is a non-equivalent control group quasi-experimental design to test the effectiveness of educational programs on human tissue donation for nursing students to change the perception of human tissue donation. The subjects of the study were 75 nursing students located in U city, 38 in the experimental group and 37 in the control group. The data were analyzed using SPSS/WIN 23.0. The average age was 22.39±0.75 years old, women 84.2% and there was no difference in general characteristics and prior data between the two groups. Knowledge (F=-8.921, p<).001, Attitude (F=-5.414, p<).001, perception of death (F=-3.075, p=).004) showed a significant difference, and the educational intervention of nursing students developed to promote human tissue donation showed a positive effect on human tissue donation. When programs to be applied to educational institutions that train not only medical personnel but also experts in other fields must be developed, the establishment and stability of the human tissue donation culture will be solidified. It is also suggested that health care campaigns and education in public educational institutions should be conducted together.

  • Across the world, 'housing' comprises a significant portion of wealth and assets. For this reason, fluctuations in real estate prices are highly sensitive issues to individual households. In Korea, housing prices have steadily increased over the years, and thus many Koreans view the real estate market as an effective channel for their investments. However, if one purchases a real estate property for the purpose of investing, then there are several risks involved when prices begin to fluctuate. The purpose of this study is to design a real estate price 'return rate' prediction model to help mitigate the risks involved with real estate investments and promote reasonable real estate purchases. Various approaches are explored to develop a model capable of predicting real estate prices based on an understanding of the immovability of the real estate market. This study employs the LSTM method, which is based on artificial intelligence and deep learning, to predict real estate prices and validate the model. LSTM networks are based on recurrent neural networks (RNN) but add cell states (which act as a type of conveyer belt) to the hidden states. LSTM networks are able to obtain cell states and hidden states in a recursive manner. Data on the actual trading prices of apartments in autonomous districts between January 2006 and December 2019 are collected from the Actual Trading Price Disclosure System of the Ministry of Land, Infrastructure and Transport (MOLIT). Additionally, basic data on apartments and commercial buildings are collected from the Public Data Portal and Seoul Metropolitan Government's data portal. The collected actual trading price data are scaled to monthly average trading amounts, and each data entry is pre-processed according to address to produce 168 data entries. An LSTM model for return rate prediction is prepared based on a time series dataset where the training period is set as April 2015~August 2017 (29 months), the validation period is set as September 2017~September 2018 (13 months), and the test period is set as December 2018~December 2019 (13 months). The results of the return rate prediction study are as follows. First, the model achieved a prediction similarity level of almost 76%. After collecting time series data and preparing the final prediction model, it was confirmed that 76% of models could be achieved. All in all, the results demonstrate the reliability of the LSTM-based model for return rate prediction.

  • The purpose of this study is to analyze the success and failure factors of the Seoul Garden show to redefine the purpose and goal of the Seoul Garden show in the future, and to create a foundation for the Seoul Metropolitan Government to contribute to the popularization and spread of garden culture and improvement of emotional life. In order to achieve the above purpose, a survey was conducted on two groups of the general public and exhibition participants. The contents of the survey include identifying satisfaction factors and problems with the Seoul Garden show, and establishing the direction of the Seoul Garden show. As for the factors of success, the number of writers was the highest, and the improvements were overall for each element of the Seoul Garden show, but mainly for industrial exhibitions, rest areas, and publicity. In addition, the Seoul Garden show should be held in the old park with the aim of spreading, popularizing, and living the garden culture, and many gardens should be created around the artist's garden. The Seoul Garden show is contributing to society in many ways, and there are some improvements, but considering the high willingness to revisit the Seoul Garden show, it can be said that the Seoul Garden show so far is valuable enough.

  • Currently, NFTs have no dominant application except for the proof of ownership for digital content, and it also have small liquidity problem, which makes their price difficult to predict. Real estate usually has very high barriers to investment due to its high pricing. Real estate can be converted into NFTs and also divided into small value fungible tokens (FTs), and it can increase the the volume of the investor community due to more liquidity and better accessibility. In this document, we implement and design a system that allows ordinary users can invest on high priced real estate utilizing Black Litterman (BL) model-based Portfolio investment interface. To this end, we target a set of real estates pegged as collateral and issue NFT for the collateral using blockchain. We use oracle to get the current real estate information and to monitor varying real estate prices. After tokenizing real estate into NFTs, we divide the NFTs into easily accessible price FTs, thereby, we can lower prices and provide large liquidity with price volatility limited. In addition, we also implemented BL based asset portfolio interface for effective portfolio composition for investing in multiple of real estates with small investments. Using BL model, investors can fix the asset portfolio. We implemented the whole system using Solidity smart contracts on Flask web framework with public data portals as oracle interfaces.

  • Despite the recent progress in public health measures, malaria remains a troublesome disease that needs to be eradicated. It is essential to develop new antimalarial medications that are reliable and secure. This report evaluated the pharmacokinetics and antimalarial activity of 1,2,6,7-tetraoxaspiro[7.11]nonadecane (N-89) using the rodent malaria parasite Plasmodium berghei in vivo. After a single oral dose (75 mg /kg) of N-89, its pharmacokinetic parameters were measured, and t1/2 was 0.97 h, Tmax was 0.75 h, and bioavailability was 7.01%. A plasma concentration of 8.1 ng/ml of N-89 was maintained for 8 h but could not be detected at 10 h. The dose inhibiting 50% of parasite growth (ED50) and ED90 values of oral N-89 obtained following a 4-day suppressive test were 20 and 40 mg/kg, respectively. Based on the plasma concentration of N-89, we evaluated the antimalarial activity and cure effects of oral N-89 at a dose of 75 mg/kg 3 times daily for 3 consecutive days in mice harboring more than 0.5% parasitemia. In all the N-89-treated groups, the parasites were eliminated on day 5 post-treatment, and all mice recovered without a parasite recurrence for 30 days. Additionally, administering oral N-89 at a low dose of 50 mg/kg was sufficient to cure mice from day 6 without parasite recurrence. This work was the first to investigate the pharmacokinetic characteristics and antimalarial activity of N-89 as an oral drug. In the future, the following steps should be focused on developing N-89 for malaria treatments; its administration schedule and metabolic pathways should be investigated.

  • Child policy has focused on needy children with special emphasis on residual services but youth policy has implemented to promote capabilities of general adolescents by various activities. The fragmented implementation of child-youth policy by several ministries resulted in possible redundancy of target groups and insufficient service delivery system. Thus, the Ministry of Health, Welfare, and Family Affairs has pushed forward to integrate service delivery systems in child-youth policy after the former Ministry of Health and Welfare and the Government Youth Commission were integrated as part of a government reorganization plan. The purpose of this study is to review limitations of Lee Myung-bak government's plan to integrate child-youth policy and to make important suggestions for effective integration. Lee Myung-bak government's plan seeks to help children and adolescents prepare for the future and move forward with dreams and hope. However, this plan has fatal problems of overemphasizing the efficiency of finance without expansion of budget for children and adolescents. To achieve well-being tailored to one's life cycle, the full-scale expansion of budget is indispensible through the induction of the special fund or the special tax for children and adolescents. Fortunately, Lee Myung-bak government recognized child-youth policy as the social investment that would heighten national competitiveness in the long term, but there was insufficient child-youth policy infrastructure for new implementation. Therefore, Lee Myung-bak government needs a new design for integrated and universal child-youth policy that should take into account national human resource development plan and its economic development policy. The public responsibility for children and adolescents should be strengthened and, in addition, the network function in service delivery system should be complemented.

  • As the cloud computing market grows, a variety of cloud services are now reliably delivered. Administrative agencies and public institutions of South Korea are transferring all their information systems to cloud systems. It is essential to develop security solutions in advance in order to safely operate cloud services, as protecting cloud services from misuse and malicious access by insiders and outsiders over the Internet is challenging. In this paper, we propose a zero trust model for cloud storage services that store sensitive data. We then verify the effectiveness of the proposed model by operating a cloud storage service. Memory, web, and network forensics are also performed to track access and usage of cloud users depending on the adoption of the zero trust model. As a cloud storage service, we use Amazon S3(Simple Storage Service) and deploy zero trust techniques such as access control lists and key management systems. In order to consider the different types of access to S3, furthermore, we generate service requests inside and outside AWS(Amazon Web Services) and then analyze the results of the zero trust techniques depending on the location of the service request.

  • It is inevitable for college students to be confused when they first face university education, which requires them to be self-reliant and responsible, after finishing their course of education, which is passive under control of period and environment, in primary, middle, and high schools. Introduction to college courses, which require students to be subjective and responsible, to be taken after chronically and environmentally controlled primary and secondary education, are but confusing. In this stage, college education should provide ground for educational system so that students can escape from repetitively enforced way of studying of fixed curriculums and study creatively and subjectively while befitting each individual's aptitude. For instance, in programming classes in engineering school, students scholastic achievements are closely interrelated with the professor's educational principles. A change in method of education, from one previously focused on theoretical contents to one centered on practices and experiments, can reap good results. Also, as the need arose for introduction of practice-focused evaluation system, from recognition-centered professor evaluating system to enablement of actively developing creative and self-reliant way of learning, we applied the Rublic System. It is a feedback system that all or most students become the evaluators, of which the indicators of evaluation such as category, standard, and score are public. We have looked into whether or not there has been an improvement in GPAs of students, and if there exists an improvement then what efforts should be made to solidify the system.
