Background: Biomarkers and clinical indices have been investigated for predicting mortality in patients with coronavirus disease (COVID-19). We explored the prognostic utility of procalcitonin (PCT), presepsin, and the Veterans Health Administration COVID-19 (VACO) index for predicting 30-day-mortality in COVID-19 patients. Methods: In total, 54 hospitalized COVID-19 patients were enrolled. PCT and presepsin levels were measured using the Elecsys BRAHMS PCT assay (Roche Diagnostics GmbH, Mannheim, Germany) and HISCL Presepsin assay (Sysmex, Kobe, Japan), respectively. The VACO index was calculated based on age, sex, and comorbidities. PCT and presepsin levels and the VACO index were compared using ROC curve, Kaplan–Meier method, and reclassification analysis for the 30-day mortality. Results: ROC curve analysis was used to measure PCT and presepsin levels and the VACO index to predict 30-day mortality; the optimal cut-off values were 0.138 ng/mL for PCT, 717 pg/mL for presepsin, and 12.1% for the VACO index. On Kaplan–Meier survival analysis, hazard ratios (95% confidence interval) were 15.9 (4.1-61.3) for PCT, 26.3 (6.4-108.0) for presepsin, and 6.0 (1.7-21.1) for the VACO index. On reclassification analysis, PCT and presepsin in addition to the VACO index significantly improved the prognostic value of the index. Conclusions: This study demonstrated the prognostic utility of measuring PCT and presepsin levels and the VACO index in COVID-19 patients. The biomarkers in addition to the clinical index were more useful than the index alone for predicting clinical outcomes in COVID-19 patients.

The objective of this study was to examine the changes of the pulse waves according to three regions of radial artery. In Korean traditional medicine, the pulse shape of three regions of radial artery can give different information about the patient’s health condition. Therefore we examined the characteristics of pulse wave measured on each region. Fifty one subjects participated in this study. One region was designated at radial bone and two regions were designated 1cm apart from it. Applied pressure, energy, period, amplitude of first peak and first valley, amplitude of second peak and second valley, amplitude of third peak, time to first peak and first valley, time to second peak and second valley, time to third peak, systolic duration, diastolic duration and area of pulse waves were analyzed. P-values of applied pressure, energy, amplitude of first peak, amplitude of second peak, amplitude of second valley, time to first peak, time to second peak and area of pulse wave were less then the significance level of 0.05. Therefore we could conclude that the pulse wave obtained from three regions of radial artery had different characteristics. This preliminary study showed that we should designate exact position before pulse wave analysis.

Background: To ensure safe red blood cell (RBC) transfusion practice, it is important to comply with storage and transport requirements of RBC units. We conducted a comprehensive survey on the practice of RBC transport and storage to explore the awareness of and compliance with the 30-minute rule, the current status of RBC unit transport, and possible utility of temperature indicators (TIs) to reduce RBC wastage. Methods: From June to August of 2019, 64 blood bank physicians (14 questions) in 64 secondary- and tertiary-care hospitals and 673 nurses (13 questions) in 42 tertiary-care hospitals replied to a questionnaire survey. The results of the survey were analyzed with descriptive statistics. Results: Among the physicians surveyed, 97.0% (N=62) of hospitals had transfusion guidelines in place. The RBC wastage in 2018 ranged from less than five units to more than 200 units. Among the nurses surveyed, 99.4% (N=669) were aware of and complied with the 30-minute rule; 13.5% (N=91) of the nurses had experience of RBC wastage due to violation of the 30-minute rule. Both physicians (67%, N=43) and nurses (83.1%, N=559) responded that TIs would help reduce RBC wastage. Conclusions: This is the first survey on the practices related to RBC transport and storage in Korea. This study provides fundamental data on current practice for the blood cold chain, insights into RBC wastage, and highlights the utility of TIs.
Investigations on IT/ET and IT/BT Convergence Technology Using Power Line Communications
Mikyoung Park(박미경),Young Huh(허영),Sang Ki Oh(오상기) 대한전기학회 2006 대한전기학회 학술대회 논문집 Vol.2006 No.10
Due to enhanced high IT (information technology) development, IT-based technology convergences such as IT/ET(electric technology), IT/BT(biology technology) and IT/NT(nano technology) are actively merging trend and their applications spread wide. In this paper PLC (power line communication), one of the merging IT, is investigated as one of the potential IT candidates for IT/ET and IT/BT convergence technology for DLC (direct load control) or bio-medical engineering such as ubiquitous health cares or D2H2 (distributed diagnosis and home health care).

This paper shows the results of a survey on the perception and viewpoints of Korean English-learning students on American culture and the result of reference research on the characteristics of American culture. Seventy Korean university students participated in the survey, which asks students their perception and view points on American culture. Editorials from major American press were used for reference research. Findings of this survey are: 1) Korean students widely perceive American culture relatively correctly in the systematic aspects as well as in the way of everyday life. 2) Korean students show comparatively poor recognition of American culture in some aspects: the social distance dramatized by American individualism, the aggressive defense culture, the social insecurity fueled by gun culture, and the non-interfering political culture. 3) Korean students view American culture neutrally or positively though they perceive the negative aspects of American culture. This study proves Korean students have unrealistic viewpoint on American culture with uncertain reasons.
연구논문 02 : 재일한국인 지방참정권 획득 문제의 최근 동향
박미경 ( Mikyoung Park ) 국민대학교 일본학연구소 2013 일본공간 Vol.13 No.-
일본에 체재하는 외국인등록자 수는 2011년 법무성 통계 기준 약 208만 명으로 전 인구의 약 2%에 이르고 있다. 재일한국인과 같이 외국인이더라도 국민과 동일한 생활실태를 가지는 자의 존재가 점점 늘어나게 되면서 일본 내에서도 국민과 외국인의 차이점에 대한 검토가 이루어져 오고 있다. 특히 외국인의 참정권에 대한 주장은 90년대 재일한국인들에 의해 이루어진 것이다. 그들은 국제인권문 서들에서 규정하고 있는 바대로 정주외국인에게 지방 선거에 대한 참정권이 인정되어야 한다고 주장하였다. 이에 일본은 공생하며 살아가는 국제 사회의 일원으로서, 많은 사람들이 공생함으로써 새로운 일본사회가 창출될 수 있다고 하는 미래를 바라보는 관점이 필요하다. 최근의 국가나 민족의 개념에서 볼 때 국가라고 하는 개념을 상대화하는 경향과 일본에 오랫동안 거주한 사람들이 일본사회를 일부 형성해 나가고 있다고 하는 점도 일본은 인정해야 할 것이다. 또한 이미 채택한 국제인권문서들에 대한 국가의 의무, 세계에서의 일본 국가 위치를 상기해야 할 것이다. The Number of foreigners in Japan is rising since the end of thelase century because of the change of the migration policy both for workers and students and 2% percentage of Japanese population was occupied by foreigners in 2011. The movement for foreigner``s suffrage became active in 90``s by Korean residents in Japan (Zainichi) because of our historical legal status including nationality, but local governments which were aware of international human rights devised the system of giving the long-term residents the opportunity to participate in residence autonomy. So, Japan is now changing toward Symbiosis Society and government is becoming aware of fulfilling alien`s rights which is essential for coming society. Under such circumstances, Japanese and government are required to deepen the understating about International Human Rights and make them effectives as international regime as one of the influential members on the globe.
