Objectives: This study compares cases of Dalgubeol Health Care Project, 301 Network Project, and 3 for 1 Project based on program logic models to derive measures for promoting integrated healthcare and welfare services centered around medical institutions. Methods: From January to December 2021, information on the implementation systems and performance of each institution was collected. Data sources included prior academic research, project reports, operational guidelines, official press releases, media articles, and written surveys from project managers. A program logic model analysis framework was applied, structuring the information based on four elements: situation, input, activity, and output. Results: All three projects aimed to address the fragmentation of health and welfare services and medical blind spots. Despite similar multidisciplinary team compositions, differences existed in specific fields, recruitment scale, and employment types. Variations in funding sources led to differences in community collaboration, support methods, and future directions. There were discrepancies in the number of beneficiaries and medical treatments, with different results observed when comparing the actual number of people to input manpower and project cost per beneficiary. Conclusions: To design an integrated health and welfare service provision system centered on medical institutions, securing a stable funding mechanism and establishing an appropriate target population and service delivery system are crucial. Additionally, installing a dedicated department within the medical institution to link activities across various sectors, rather than outsourcing, is necessary. Ensuring appropriate recruitment and stable employment systems is needed. A comprehensive provision system offering services from mild to severe cases through public-private cooperation is suggested.

Group oriented multicast service is a prerequisite for the current application system for remote lecture and customer service. IP multicast is used to be generally accepted as an internet standard. IP multicast which is designed to support network based replication model can efficiently use host and network resource, however it has some weak points that it has to support IP multicast in the internet by adding multicast-capable internet infrastructure such as router and is vulnerable to security by using public IP address for group identifier. Therefore we propose the trigger based application level multicast model that can enhance both scalability and security by separating the functions, which send and receive message to solve these problems. Our suggested model is expected to ensure the promotion of quality of service and reliability.

This study reviews how an aging society can be connected to the urban-built environment, transportation system, infrastructure, and climate change topics from the perspective of policy and innovation in science and technology. Each topic was described with the aging society that we will encounter in the near future. Based on the expected discussions, we suggested how policy and technological innovations may interact with the new emerging society. Especially, digital transformation is expected to hyper-connect the aging society beyond physical barriers where numerous policies and innovations in science and technology shed light on the elderly population. We observe, however, that this cannot be achieved only by the government sector; rather, municipal governments and local communities, as well as private sectors, all together need to prepare for the new society of the aging population. Furthermore, an ideal approach is to accommodate multidisciplinary studies that can address the policy and technological innovations simultaneously and collectively. By doing so, we can minimize the negative impacts when an aging society approaches.

As composite materials are gaining wide acceptance in aircraft structure, repair of damaged composite is becoming an important issue. The issues in composite repair include high cost, material interchangeability, water ingression, and structural integrity. To address these problems, researchers have studied on the composite repair in various aspects. In this paper, an Internet-based advisory service (called Repair Advisory Service, RAS) for composite repair is proposed to increase efficiency for repair process. In the RAS system the web browser is used as its user interface, which provides easy access to the service. The RAS server provides web-based tools for failure prediction, Structural Repair Manual (SRM), automated prepreg cutting process, material properties, inventory and knowledge base. The computer codes implemented for repair design estimate the tensile failure and shear failure of repaired structures. The prediction of failure is based on the maximum strain criterion for tensile failure while elastic-perfect plastic shear failure model is applied for interfacial failure. The OEM's SRM is provided in the PDF format for viewing and searching by web browsers instead of looking up paper version SRM. The knowledge base in this site offers a room to share and distribute ideas, memos, publications, or suggestions from the repair engineers. The fabrication tool of RAS reads repair geometry from engineers then generates a CNC toolpath to cut prepreg patches. The RAS service is open to public and available at http://nano.gsnu.ac.kr/. Broad feedback from field technicians and engineers is welcome to improve the usefulness of RAS.

As the management and preservation of the environment become an important social issue, information required to support environmental task is required. So, there is an increasing demand for environmental information and appropriate systems to manage it. The vast volume of environmental data is distributed in different knowledge domains and systems. Environmental data objects have the complex structure containing environmental quality data and attribute data. Environmental information systems must be able to address these properties. This research has aimed at constructing well-defined schema design of environmental data, and making system architecture that environmental data kept by authorities should be made available to the public user. There are 3 major components in environmental information systems architecture ; User interface, Catalog libraries, Communication Provider. Web browsers provide consistent and intuitive user interfaces on Internet. The communication provider is a collection of diverse CGI functions. The main roles of the CGIs are to build interfaces between the Web, databases. Catalog libraries is libraries of various matadata including administration matadata. Administration matadata support the environmental administration and the managerial aspects of environmental data rather than explain a database itself or its properties.

Considerable effort has been made to address the issue of occupational health and environmental exposure to mercury. This review reports on the current literature of mercury exposure and health impacts on dental personnel. Citations were searched using four comprehensive electronic databases for articles published between 2002 and 2015. All original articles that evaluated an association between the use of dental amalgam and occupational mercury exposure in dental personnel were included. Fifteen publications from nine different countries met the selection criteria. The design and quality of the studies showed significant variation, particularly in the choice of biomarkers as an indicator of mercury exposure. In several countries, dental personnel had higher mercury levels in biological fluids and tissues than in control groups; some work practices increased mercury exposure but the exposure levels remained below recommended guidelines. Dental personnel reported more health conditions, often involving the central nervous system, than the control groups. Clinical symptoms reported by dental professionals may be associated with low-level, long-term exposure to occupational mercury, but may also be due to the effects of aging, occupational overuse, and stress. It is important that dental personnel, researchers, and educators continue to encourage and monitor good work practices by dental professionals.

As information technologies are developing, the improvement of the quality of life becomes worldwide issues. Especially, to improve the quality of life of a patient suffering intermittent diseases, in addition to the some portable equipments for measuring, analyzing, and notifying the status of the patients, methods of communication for seamless transmission of the measured data over to the remote site, such as an emergency center or a hospital, are required. In this paper, we address a seamless transmission of patient monitoring data such as ECG from a moving patient to a remote site, wherever the patient may be. We divide the whole environments into two wireless communication environments: an indoor one based on WLAN and an outdoor one based on CDMA cellular network in which the patient is assumed to move anywhere. We develop algorithms, implement them on a PDA-based hardware platform, and show some of the results for handover between the two environments in addition to the data transmission for each of the two environments.

While the notified crude incidence rates(per 100,000 persons, CIR) of new tuberculosis between 2016 and 2017 decreased in nationwide and 16 provinces, except Jeju Province, Korea. The aim of this study was to compare CIRs of Jeju Province and nationwide by calendar years and age groups in order to interpret the increasing trend of CIR in Jeju Province. The data source was the Integrated Diseases and Health Control System of the Korea Centers for Disease Control and Prevention. The selection criteria were the notified new cases as tuberculosis, who had the address as Jeju Province at diagnosis, between 2011 and 2018. The 95% confidence interval of CIR was estimated based on Poisson distribution. There was not statistically significant difference of CIRs between Nationwide and Jeju Province of 2011 and 2018, except 2016. Especially the CIR of group aged over 65 years in Jeju Province, 2016 was significantly lower compared to Nationwide CIR. But, the CIR of group aged 30~50 between 2017 and 2018 showed significantly higher compared to Nationwide CIR. Based on the results, the fact of increasing CIR from 2016 to 2017 in Jeju Province might be interpreted as an introduction of new tuberculosis screening project rather than real increased CIRs.

In the public healthcare, a computational system that can automatically and efficiently detect and classify falls from a video sequence has significant potential. With the advancement of deep learning, which can extract temporal and spatial information, has become more widespread. However, traditional 3D CNNs that usually adopt shallow networks cannot obtain higher recognition accuracy than deeper networks. Additionally, some experiences of neural network show that the problem of gradient explosions occurs with increasing the network layers. As a result, an enhanced three-dimensional ResNet-based method for fall detection (3D-ERes-FD) is proposed to directly extract spatio-temporal features to address these issues. In our method, a 50-layer 3D residual network is used to deepen the network for improving fall recognition accuracy. Furthermore, enhanced residual units with four convolutional layers are developed to efficiently reduce the number of parameters and increase the depth of the network. According to the experimental results, the proposed method outperformed several state-of-the-art methods.

Purpose: This study aims to describe and understand the meaning and nature of community health practitioners' coping with COVID-19. Methods: In-depth interviews were conducted with 12 community health practitioners from August to October 2021, to describe and understand the nature of their coping with COVID-19. The collected data were examined and described based on Colaizzi's phenomenological method. Results: 16 theme clusters and five categories were derived from the community health practitioners' experience of coping with COVID-19. The categories derived were: a war that began without notice, a variety of correspondence tasks assigned, struggling to fulfill given roles, correspondence tasks becoming more systematic, and a fight that has not yet ended. Conclusion: Community health practitioners handled various response tasks related to COVID-19, and faithfully fulfilled their professional roles while performing the primary task of medical care. Hence, attention is required on issues related to the establishment of the national emergency healthcare system and improvement of professional competence of community health practitioners even after the COVID-19 pandemic is over. Furthermore, it is necessary to make ceaseless efforts to address those issues and, in order to do so, social interest and institutional support are needed.
