  • Purpose: The purpose of this paper was to investigate community health status and related factors using community health and social indicators. Method: Data sources were reviewed and data for 10 categories, 75 indicators were collected. Community health status and health-related factors were categorized, and the means and standard deviation of individual indicators were obtained and standardized scores were calculated. In addition, through factor analysis of individual indicators by category using the scores and using the resultant factor coefficients as weights, indexes were calculated by area. Correlation and regression were analyzed. Result: Each indicator was highly correlated with each index, and the indexes were highly correlated with one another. Correlation coefficients were above 0.8 between community health index and population, education, housing, and economy, between population and education, housing and economy, between education and housing and economy, and between housing and economy, environment and industry. But multicollinearity was not found in the result. Significant factors on community health index were population, health personnel and facilities, education, housing and economy, and R-square were 92.4%. Conclusion: Health determinants such as population, health personnel and facilities, education, housing and economy could be influencing factors on community health in community level. These results showed the importance of intersectoral collaboration within a local government. Overall community health can be enhanced by intersectoral collaboration.

  • This study proposes a battery state-of-health estimation method by applying a feature extraction technique. The technique that can improve estimation performance is the process of identifying and extracting meaningful data. To apply a data-driven-based aging state estimation method to batteries, health indicators are used as training data. However, limitations occur in extracting health indicators from charge/discharge cycles. This study proposes a deep-learning-based battery state-of-health estimation method that applies feature extraction techniques to compensate for this problem. According to the performance evaluation result of the proposed method, it has a low estimation error of 0.3887% based on an absolute error evaluation method.

  • Nowadays, the environmental conservation has become a hot issue. Also the sustainable city issue is recognized as one of the most important tasks to be solved urgently for urban development. Therefore, the current indicator for sustainable city has been analyzed only as a segment of the environmental indicator which is one kind of branch of social indicator. However, considering the degree of pollution and heightened concern, it is time to develop a new and improved framework for the analysis of the sustainable city indicator. This study aims for the development of sustainable city indicator and the examination of practical method for the use of them. Urban sustainable city indicators are based on the "Pressure-State-Response (PSR) framework" which has been adopted by Organization for Economic Cooperation and Development (OECD). The indicators suggested in this study is composed of the following categories: 1. Indicators of natural environment itself, such as land structure (available land use index etc.), bio-species (bio-diversity index etc.), environment resources (water quantity index etc.) 2. Indicators of relationship between man and environment, such as sustainability of using material (recycle of water index etc.), pressure size (pressure index on air etc.), effort of prevention (environmental basic facility index, etc.) 3. Indicators of environmental state, such as landscape and culture (historical & cultural index etc.), environmental pollution (air pollution index etc.) A sustainable city environment is necessary and obtainable, yet its realization seems to be difficult. The urban pollution problems have become more serious than ever before thus requiring much interest. Therefore, this kind of study is meaningful for the establishment of policy objective, and the development and management environmentally sound and sustainable cities.

  • An h-adaptive scheme of first-order least-squares meshfree method is presented. A posteriori error estimates, which can be readily computed from the residual, are also presented. For elliptic problem the error indicators are further improved by applying the Aubin-Nitsche method. In the proposed refinement scheme, Voronoi cells are utilized to insert nodes at appropriate positions. Through numerical examples, it is demonstrated that the error indicators reveal good correlations with the actual errors and the adaptive first-order least-squares meshfree method is effectively applied to the localized problems such as the shock formation in fluid dynamics.

  • 북한(北韓)의 GNP를 추정(推定)하는 데에 가장 큰 어려움은 첫째, 통계자료(統計資料)의 절대적(絶對的) 부족(不足), 둘째 GNP의 달러환산(換算)에 적합한 환율(換率)의 부재(不在)이다. 실물지표(實物指標)에 의한 GNP추정방법(推定方法)은 요구(要求)되는 통계(統計)의 양(量)이 많지 않으며, 또한 비교국가군(比較國家群)의 달러GNP와 실물지표(實物指標)들과의 관계를 추정(推定)하여 이를 북한의 실물지표(實物指標)에 적용함으로써 바로 달러GNP를 구할 수 있기 때문에 북한(北韓)GNP 추정(推定)에 특히 적합한 방법이라 하겠다. 실물지표접근법(實物指標接近法)으로 추정(推定)한 결과 1990년 북한(北韓)GNP는 273억(億)달러, 1인당GNP는 1,273달러로 나타났다. 기존의 다른 추정결과(推定結果)들과 비교해 보면 방법론상(方法論上)의 차이(差異)에도 불구하고 실물지표접근법(實物指標接近法), 통일원(統一院), 재정비율접근법(財政比率接近法)의 추정규모가 상당히 비슷한 수준이었으며, GNP추정결과가 시사(示唆)하는 무역규모(貿易規模)/GNP, 재정규모(財政規模)/GNP 비율(比率) 등도 타당(妥當)한 수준이었다. 한편 구소련(舊蘇聯)의 국제경제정치연구소(國際經濟政治硏究所)의 추정GNP는 북한발표(北韓發表) 재정규모(財政規模)보다 작은데다가 무역규모(貿易規模)/GNP 비율이 58%나 되어 GNP가 지나치게 과소평가(過小評價)된 것으로 보이며, 영국(英國)의 국제전략문제연구소(國際戰略問題硏究所)는 추정시(推定時) 과대평가(過大評價)된 공정환율(公定換率)을 사용하였고 추정결과(推定結果)가 시사(示唆)하는 무역규모(貿易規模)/GNP 비율이 7~10%에 불과하여 GNP가 과대평가(過大評價)된 것으로 보인다. 실물지표접근법(實物指標接近法)은 단순추정방법(單純推定方法)(Short-cut method)이 가지고 있는 한계에도 불구하고 북한의 통계사정(統計事情)이 크게 개선될 때까지는 북한(北韓)GNP를 추정(推定)하는 데 유용(有用)할 것으로 판단된다.

  • Purpose: The purpose of this study was to explore the use of outcome indicators and perception of outcome evaluation of oncology advanced practice nurses (APNs). Method: A total of 111 oncology APNs from hospitals which have over 400 beds were surveyed. The participants' use of outcome indicators and perception of outcome evaluation were collected using a questionnaire including 84 outcome indicators for APNs developed by Sung et al. and 13 items on APNs' contribution to the hospitals developed by Kleinpell (2005). Data were analyzed using descriptive statistics, t-test, and $x^2$ test. Result: Twelve items out of 84 outcome indicators were used over 50% of the time and 57 items could be used in the future by the participants. Seven of the 10 top-ranking outcome indicators in use were education related and were also expected to be used frequently in the future. The score for participants' perception of outcome evaluation was average-high, 3.82 out of 5. Conclusions: The results of the study show that the main outcome indicator for oncology APNs is education related, and thus the use of education related outcome indicators is recommended to make oncology APNs' activities be more visible.

  • Altmetrics or alternative metrics gauge the digital attention received by scientific outputs from the web, which is treated as a supplement to traditional citation metrics. In this study, we performed a meta-analysis of correlations between classic citation metrics and altmetrics indicators of library and information science (LIS) articles. We followed the systematic review method to select the articles and Erasmus Rotterdam Institute of Management Guidelines for reporting the meta-analysis results. To select the articles, keyword searches were conducted on Google Scholar, Scopus, and ResearchGate during the last week of November 2021. Eleven articles were assessed, and eight were subjected to meta-analysis following the inclusion and exclusion criteria. The findings reported negative and positive associations between citations and altmetric indicators among the selected articles, with varying correlation coefficient values from -.189 to 0.93. The result of the meta-analysis reported a pooled correlation coefficient of 0.47 (95% confidence interval, 0.339 to 0.586) for the articles. Sub-group analysis based on the citation source revealed that articles indexed on the Web of Science showed a higher pooled correlation coefficient (0.41) than articles indexed in Google Scholar (0.30). The study concluded that the pooled correlation between citation metrics with altmetric indicators was positive, ranging from low to moderate. The result of the study gives more insights to the scientometrics community to propose and use altmetric indicators as a proxy for traditional citation indicators for quick research impact evaluation of LIS articles.
