Humanities-collaborated practices in various fields have been supported by several governmental policies as a way to overcome recent social problems. Museum, due to its roles in preserving and sharing cultural and historical heritage for the development of society and communities, has emerged as a key base for the humanities-collaborated practices. This study, in this context, aimed to analyze how the humanities-based museum education programs have been practiced in the museums, which, in turn, might provide a basic data for the future direction and development of the programs and the related governmental policy as well. For this purpose, this study first examined theoretical framework for the link between humanities and museum education, from which a survey was developed. The survey was conducted to 75 museum educators who have been in charge of humanities-based educational programs. The result showed that most programs seemed to reflect the basic direction and purpose of the humanities-linked with museum education. Yet, more needs were found in terms of the educational themes and methods which can facilitate multicultural literacy and reflective thinking and activities within experiential learning environments.

In Wireless Sensor Network, transmission errors are frequently occurred due to the node failure, battery discharge, and interference by objects. Although Directed Diffusion has been considered as a prominent Data-centric routing algorithm, it revealed some weaknesses at this kind of unexpected network errors. In order to address the problem, we proposed a radio-aware routing algorithm for improving reliability of Directed Diffusion in Wireless Sensor Networks. The proposed algorithm is aware of the network status based on the radio information of MAC and PHY layers using a cross-layer approach. The link quality and the node failure information from the acquired network status were used to decide an alternative path to provide a reliable data transmission in error-prone sensor networks. The proposed algorithm showed its effectiveness of the data delivery rate and data ratio with several simulations consisting of various error rates and the number of nodes.

This paper aims to propose a policy for linking and utilizing spatial data for resilient spatial planning against disaster due to climate change by analyzing the current status of spatial data in the fields of urban planning, environmental planning and disaster prevention. To do so, spatial planning guidelines and the current status of utilizing spatial data in each field were identified by conducting a literature review and phone/face-to-face interviews with professionals and representatives of relevant institutions. As a result, the lists of spatial data were drawn up which can be utilized or linked with each other for developing an official spatial plan at a local government level. On the basis of these results, policy plans were proposed to link and utilize spatial data among urban planning, environmental planning and disaster prevention fields for climate change adaptation spatial planning.

Purpose: This report compared the diagnostic effectiveness between ultrasmall superparamagnetic iron oxide (USPIO) and gadolinium (Gd) based magnetic resonance imaging (MRI) for differentiation of axillary status in breast cancer patients. Materials and Methods: The present authors performed a meta-analysis of previous studies that compared USPIO or Gd based MRI with histological diagnosis after surgery or biopsy. We searched PubMed, EMBASE, Cochrane Library, ScienceDirect, SpringerLink, Ovid databases and references of articles to identify studies reporting data until December 2013. Pooled sensitivity and specificity were calculated for every study; summary receiver operating characteristic and subgroup analysis was done. Analyses of study quality and heterogeneity were also assessed. Results: There were 14 publications that met the criteria for inclusion in our meta-analysis. USPIO based MRI showed 0.83 (95% CI: 0.75-0.89) and 0.97 (95% CI: 0.94-0.98) for pooled sensitivity and specificity, respectively. Gd based MRI represented pooled sensitivity and specificity of 0.61 (95% CI: 0.55-0.67) and 0.90 (95% CI: 0.87-0.92) for each. Overall weighted area under the curve for USPIO and Gd based MRI were 0.9563 and 0.9051, respectively. Conclusion: USPIO based MRI had a tendency toward high pooled sensitivity and specificity in detection of axillary metastases for breast cancer. This result may mean that USPIO based MRI could be used as complementary modality to differentiate axillary status more precisely, and assist in the decision-making process regarding possible invasive procedures, such as sentinel node biopsy.

In high speed communication networks, the determination of a transmission rate is critical for the stability of a closed-loop network system with the congestion control scheme. In ATM networks, the available bit rate (ABR) service is based on a feedback mechanism, i.e., the network status is transferred to the ABR source by a resource management (RM) cell. RM cells contain the traffic information of the downstream nodes for the traffic rate control. However, the traffic status of the downstream nodes can not be directly transferred to the source node in the IP based networks. In this paper, a new rate-based congestion control scheme using an exponential weighted moving average algorithm is proposed to build an efficient feedback control law for congestion avoidance in high speed communication networks. The proposed congestion control scheme assures the stability of switch buffers and higher link utilization of the network. Moreover, we note that the proposed congestion scheme can flexibly work along with the increasing number of input sources in the network, which results in an improved scalability.

The Public Data Portal(data.go.kr) is a gateway for searching and using public data in South Korea. In 2021, the Ministry of Public Administration and Security established individual portal maintenance plans. Individual portals refer to portals built by public institutions in Korea other than the public data portal. According to the maintenance plan, the Korea Intelligence Information Society, the operator of the public data portal, needs to establish operating and data integration plans to link the public data portal and individual portals. In this study, we investigated the current operating status and data integration methods of the public data portal in South Korea, the United States, the United Kingdom, and France, and proposed that the adoption of a top-down approach is efficient when integrating data. In addition, we divided the specific procedures that should be pursued when integrating data into five stages: determination of data integration standard methods, analysis of metadata status, expansion of operating infrastructure, confirmation of data import, and launch of services.

Even in 2022, when medical science is highly developed, pandemic infectious diseases continue to occur. COVID-19, which occurred in 2019, is highly contagious and has caused many infections. In Korea, temporary screening clinics, such as screening clinics and respiratory clinics, have been added to prevent the spread of COVID-19, but there are problems such as a bottleneck due to the large number of people who want to take the test, and this creates a bottleneck. In order to solve the problem, this study aims to identify people who want to be tested for COVID-19 in a screening clinic in real time. It uses a real-time database to link with screening clinics and provides users with the real-time status of each screening clinic. Using the app, users can check the status of screening clinics in real time and can select a clinic smoothly.

Ethiopia is branded as the Water Tower of Africa because of its abundant inland water bodies that may be used sustainably to boost the economy. This review article's goal is to examine the current status and future potential of Ethiopia's fisheries, with a special focus on reservoirs. There are 200 known fish species (194 native, 40 endemic, and 11 exotic) in in Ethiopia's inland water. Ethiopia's fish production has increased by a factor of more than five in the past three decades (3,500 tons in 1983 to 15,681 tons in 2000 and 18,058 tons in 2010). However, fish produced in reservoirs is too low (8,059 t/year). The current fish harvests from reservoirs are significantly below the predicted potential yield, accounting for only 35% of the calculated fish production capacity. In this review, 14 potential reserves were revealed. A total of 48 fish species have been reported in these, of which 26 species (or around 54%) are present in Alwero reservoir. 19 of the 48 species that have been officially recognized belong to the Cyprinidae family and made up nearly 40% of the fish population in Ethiopian reservoirs. There has been, however, a decline in the productivity of Ethiopia's reservoir fish. Hence, actively start fishing in the numerous reservoirs that have been neglected yet, link the potential of fisheries and the benefits of the fish farming supply chain, let's begin building several other reservoirs similar to the Grand Ethiopian Renaissance Dam and beginning mechanized-based fish harvesting.

Background: It is known that obesity is one of the risk factors for breast cancer although the association may differ between ethnic groups and with the menopausal status. Recently obesity-related risk factors including serum adiponectin and insulin levels have been analyzed together with BMI in association with breast cancer risk. Materials and Methods: We measured serum high molecular weight (HMW) adiponectin and insulin levels in a hospital based case-control study, including 66 sets of Japanese female breast cancer cases and age and menopausal status matched controls. Serum levels of HMW adiponectin, insulin levels and body mass index (BMI) were examined in association with breast cancer risk with adjustment for the various known risk factors by menopausal status. Results: Women in the highest HMW adiponectin levels showed significant reduced risk of breast cancer in both pre and postmenopausal women (odds ratio (OR), 0.01; 95% confidence interval (CI), 0.00-0.26 and 0.13; 0.03-0.57, respectively). Lower BMI showed decreased breast cancer risk in both pre and postmenopausal women (OR, 0.04; 95% CI, 0.00-0.69, OR, 0.28; 95% CI, 0.07-1.11, respectively). Conclusions: These results indicated that higher serum HMW adiponectin levels and lower BMI are associated with a decreased breast cancer risk in both pre and postmenopausal women in Japan, adding evidence for the obesity link.

Objectives: The concept of the WHO's 'Health Promoting School (HPS)' has been advocated as an approach enhancing national health promotion through school. Health-promoting schools have existed internationally about 20 years. Yet there are few comprehensive evaluation results. Methods: This study is a cross-sectional survey, aiming to explore the HPS status. A total of 31 elementary, middle and high schools were included, and 260 teachers participated in the study. The schools were assessed based on tools of HPS. Results: 'School health promotion and protection services' and 'school's physical environment' had the highest scores, 80.7 score and 77.4 score, respectively. Community links and action competencies for healthy living were two areas with the lowest scores. Conclusions: These results are a good source of reference for assessment and evaluation of Health Promoting Schools programs. For the improvement of efficiency of Health Promoting Schools programs, cooperation with family and community link and support system would be necessary.
