In Cukhe, a village located in the outskirts of Hanoi, Vietnam, people suffer from a shortage of high-quality water due to an arsenic contaminated supply water resource. We installed catchments, filters and settled tanks in the existing rainwater harvesting facility to improve water quality, and ten portable rainwater tanks to provide good-quality drinking water to the poor households and kindergartens in the dry season. The triple bottom line considerations, as well as the environmental, economic, and social impacts of the rainwater harvesting (RWH) systems are examined. RWH is a sustainable method to obtain good-quality drinking water at low cost and with little energy expenditure. Education of the system also encourages that continuation of the system and expansion can lead into economic prosperity, as the safe drinking water can be sold to the community. Hence, RWH is a unique proposal as sustainable drinking supply water for improving the lives and health of residents in Cukhe and other sites where water supply sources are contaminated.

For the past 20 years, the medical education accreditation program of Korean Institute of Medical Education and Evaluation (KIMEE) has contributed greatly to the standardization and improvement of the quality of basic medical education in Korea. Now, it contributes to establishing and promoting the future of medical education. Since its inception in 2019, Accreditation Standard of KIMEE 2019 (ASK2019) aims to achieve world-class medical education through the application of learner-centered curriculum using a continuum framework for the three phases of formal medical education: basic medical education, post-graduate medical education, and continuing professional development. ASK2019 also promotes medical education which meets community needs and employs systematic assessments throughout the education process. These are important changes that can be used to gauge the future of the medical education accreditation system. Furthermore, internationalization, interprofessional education, health systems science, and on-going, permanent self-assessment systems in every medical school are emerging as important topics for the future of medical education. It's time for the medical education accreditation system in Korea to observe and adopt new trends in global medical education.

Automated damage detection through Structural Health Monitoring (SHM) techniques has become an active area of research in the bridge engineering community but widespread implementation on in-service infrastructure still presents some challenges. In the meantime, visual inspection remains as the most common method for condition assessment even though collected information is highly subjective and certain types of damage can be overlooked by the inspector. In this article, a Frequency Response Functions-based model updating algorithm is evaluated using experimentally collected data from the University of Central Florida (UCF)-Benchmark Structure. A protocol for measurement selection and a regularization technique are presented in this work in order to provide the most well-conditioned model updating scenario for the target structure. The proposed technique is composed of two main stages. First, the initial finite element model (FEM) is calibrated through model updating so that it captures the dynamic signature of the UCF Benchmark Structure in its healthy condition. Second, based upon collected data from the damaged condition, the updating process is repeated on the baseline (healthy) FEM. The difference between the updated parameters from subsequent stages revealed both location and extent of damage in a "blind" scenario, without any previous information about type and location of damage.

Purpose : This study examined the effect of a home visit cognitive training program that uses a tablet-based digital recognition rehabilitation application, Brain Doctor, on local elderly people's cognitive function and depression. Methods : This study featured 20 elderly people living in Busan Metropolitan City, South Korea, who received a voucher for a home visit service to prevent dementia. The subjects were evenly divided into an intervention group provided with Brain Doctor and a control group provided with a conventional cognitive training program. Korean version of Mini Mental State Examination (MMSE-K) and Korean version of Montreal Cognitive Assessment (K-MoCA) were used to assess cognitive function in each group. Patient Health Questionnaire-9 (PHQ-9) was used to evaluate the depression levels. Results : The intervention group showed a significant change in cognitive function and depression after the intervention (p<.05). There was a statistically significant change in cognitive function and depression between the intervention and control groups (p<.05). Conclusion : This study confirmed that Brain Doctor had a positive effect on the cognitive function and depression of elderly people in the local community. It is expected to become a useful home visit program for dementia prevention in the future.

Background: Pollinators are important ecological elements due to their role in the maintenance of ecosystem health, wild plant reproduction, crop production and food security. The pollinator-plant interaction supports the preservation of plant and animal populations and it also improves the yield in pollination dependent crops. Having knowledge about the plant-pollinator interaction is necessary for development of pesticide risk assessment of pollinators and conservation of endangering species. Results: Traditional methods to discover the relatedness of insects and plants are based on tracing the visiting pollinators by field observations as well as palynology. These methods are time-consuming and needs expert taxonomists to identify different groups of pollinators such as insects or identify flowering plants through palynology. With pace of technology, using molecular methods become popular in identification and classification of organisms. DNA metabarcoding, which is the combination of DNA barcoding and high throughput sequencing, can be applied as an alternative method in identification of mixed origin environmental samples such as pollen loads attached to the body of insects and has been used in DNA-based discovery of plant-pollinator relationship. Conclusions: DNA metabarcoding is practical for plant-pollinator studies, however, lack of reference sequence in online databases, taxonomic resolution, universality of primers are the most crucial limitations. Using multiple molecular markers is preferable due to the limitations of developed universal primers, which improves taxa richness and taxonomic resolution of the studied community.

The successful treatment of community-acquired pneumonia requires appropriate, empirical antimicrobial therapy. The etiology and antimicrobial susceptibility of major pneumonia pathogens can differ by country. Therefore, the ideal treatment guidelines for community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia for immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.

The cultivation of genetically modified (GM) crops has increased due to their economic and agronomic advantages. Before commercialization of GM crops, however, we must assess the potential risks of GM crops on human health and environment. The aim of this study was to investigate the possible impact of Bt rice on the soil microbial community. Microbial communities were isolated from the rhizosphere soil cultivated with Bt rice and Nakdong, parental cultivar and were subjected to be analyzed using both culture-dependent and molecular methods. The total counts of bacteria, fungi, and actinomycetes in the rhizosphere of transgenic and conventional rice were not significantly different. Denaturing gradient gel electrophoresis (DGGE) analysis of PCR-amplified 16S rRNA genes revealed that the bacterial community structures during cultural periods were very similar each other. Analysis of dominant isolates in the rhizosphere cultivated with Bt and Nakdong rice showed that the dominant isolates from the soil of Bt rice and Nakdong belonged to the Proteobacteria, Cloroflexi, Actinobacteria, Firmicutes, and Acidobacteria. These results indicate that the Bt rice has no significant impact on the soil microbial communities during cultivation period. Further study remains to be investigated whether the residue of Bt rice effect on the soil environment.

Sustainable development in society has become the center of focus in many fields such as industry, environment, health, culture, etc. Considering that the concept of heritage involves understanding it as a 'resource' to improve the quality of people's lives, sustainability is an important goal that heritage policy has to achieve. Adopting the definition of sustainability in the 1987 Brundtland Report, this paper defines the concept of sustainability with respect to heritage, as well as their respective roles. Following that, three action principles are presented: value-based conservation, rational decision-making, and community involvement. Two cases demonstrating how the three principles should be practiced in managing change are then illustrated. Considering that heritage can play its role as a resource once its significance is protected, this paper argues that value-based rational decision-making is of paramount importance and the first principle. Conservation aims to manage change by practicing a cyclic process of value identification, value sustaining, and value dissemination. Therefore, this paper argues that all processes should be connected in the context of heritage values. A rational decision-making process practicing value-based conservation is then suggested. This paper argues that rational decision-making can only be practiced once values are identified by objective criteria and managed by rational judgment upon impact assessment. Community involvement, the third principle, is necessary to realize value-based conservation and rational decision-making. Recognizing that a community is a beneficiary of heritage and a creator of a beneficial process at the same time, it discusses the role of community and the importance of this role in policies for the sustainability of heritage. This paper concludes with a set of recommendations to improve policies after examining the two decision-making cases.

The purpose of this study was to identify the factors impacting fear of dementia, targeting the aged in the community. The study targeted 258 seniors aged 65 or older attending the senior college or using the senior citizen community center in areas of Jeollannam-do. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and a stepwise multiple linear regression. Fear of dementia of the aged showed significant positive correlations with dementia anxiety, and aged anxiety. dementia anxiety, aged anxiety, dementia experience, use of a hearing aid, religion, level of dementia interest were significant predictors influencing fear of dementia of aged in the community, and these variables accounted for 37.2% of the variance. Therefore, this study suggests that in order to p revent fear of dementia of aged people in the primary health care setting, it is necessary to have a nurse's assessment on the factors affecting dementia as well as a multi-faceted education strategy for proper recognition of dementia.
