BackgroundThe Life Extension Medical Decision law enacted on February 4, 2018 in South Korea was the first to consider the suspension of futile life-sustaining treatment, and its enactment caused a big controversy in Korean society. However, no study has evaluated whether the actual implementation of life-sustaining treatment has decreased after the enforcement of this law. This study aimed to compare the provision of patient consent before and after the enforcement of this law among cancer patients who visited a tertiary university (...) hospital's emergency room to understand the effects of this law on the clinical care of cancer patients.MethodsThis retrospective single cohort study included advanced cancer patients aged over 19 years who visited the emergency room of a tertiary university hospital. The two study periods were as follows: from February 2017 to January 2018 (before) and from May 2018 to April 2019 (after). The primary outcome was the length of hospital stay. The consent rates to perform cardiopulmonary resuscitation (CPR), intubation, continuous renal replacement therapy (CRRT), and intensive care unit (ICU) admission were the secondary outcomes.ResultsThe length of hospital stay decreased after the law was enforced from 4 to 2 days (p = 0.001). The rates of direct transfers to secondary hospitals and nursing hospitals increased from 8.2 to 21.2% (p = 0.001) and from 1.0 to 9.7%, respectively (p < 0.001). The consent rate for admission to the ICU decreased from 6.7 to 2.3% (p = 0.032). For CPR and CRRT, the consent rates decreased from 1.0 to 0.0% and from 13.9 to 8.8%, respectively, but the differences were not significant (p = 0.226 and p = 0.109, respectively).ConclusionAfter the enforcement of the Life Extension Medical Decision law, the length of stay in the tertiary university hospital decreased in patients who established their life-sustaining treatment plans in the emergency room. Moreover, the rate of consent for ICU admission decreased. (shrink)

Gemass ihrer grundlegenden Bedeutung wurde die Ousia- und Eidoslehre des Aristoteles uber viele Forschergenerationen hinweg intensiv diskutiert und steht immer noch im Mittelpunkt der Aristoteles-Forschung. Die Lehre bleibt jedoch nur einseitig interpretiert und verstanden. Ihre bisherige Interpretation hat sich allzu sehr auf die sogenannten Substanzbucher der Metaphysik beschrankt, ohne dabei den der Lehre wesentlichen biologischen Aspekten gebuhrende Beachtung zu schenken. Der Autor schliesst diese Forschungslucke. So wird im ersten Teil des Werkes Metaphysik Z, der Haupttext der Ousialehre, sorgfaltig kommentiert, und (...) im anschliessenden zweiten Teil werden unter Bezugnahme auf die im vorhergehenden Teil erorterte Problematik drei wichtigste biologische Schriften des Aristoteles besprochen. Dadurch wird ein wesentlicher Zusammenhang zwischen der Ousia- und Eidoslehre in der Metaphysik und der Biologie hergestellt. (shrink)

Facebook research has proliferated during recent years. However, since November 2017, Facebook has introduced a new limitation on the maximum amount of page posts retrievable through their Graph application programming interface, while there is limited documentation on how these posts are selected. This paper compares two datasets of the same Facebook page, a full dataset obtained before the introduction of the limitation and a partial dataset obtained after, and employs bootstrapping technique to assess the bias caused by the new limitation. (...) This paper demonstrates that posts with high user engagement, Photo posts and Video posts, are over-represented, while Link posts are under-represented. Top-term analysis reveals that there are significant differences in the most prominent terms between the full and partial dataset. This paper also reverse engineered the new application programming interface’s ranking algorithm to identify the features of a post that would affect its odds of being selected. Sentiment analysis reveals that there are significant differences in the sentiment word usage between the selected and non-selected posts. This paper has significant implications for the representativeness of research that use Facebook page data collected after the introduction of the limitation. (shrink)

This article investigates the structure of trust in China and compares it with the U.S., using the 2000 and 2005 waves of the World Value Survey (WVS). We analyze two dimensions of trust - trust in people and trust in major companies. It is found that the level of trust has remained stable in China within the 5-year period. On the other hand, trust in major companies has declined dramatically in U.S. while trust in people has increased slightly. The structure (...) of trust in companies is different from trust in people. For both countries, individuals with higher education tend to have a higher level of trust. Individuals who are divorced tend to have lower trust in people. Individuals who think that other people are fair are more likely to trust in people. Preference for competition has a positive effect on trust in major companies. On the other hand, some differences between the two countries are observed. Perception of fairness does not affect trust in major companies in China, while it has a positive effect in U.S. in year 2006. Preference for equality has a negative effect on trust in major companies in U.S. but no significant effect in China. The pattern of trust and its changes over time may reflect differences in market conditions in the two economies. (shrink)
