<P><B>Abstract</B></P> <P>Investigating how well people adapt to heat waves and cold spells has been an important issue under climate change. Also, most of previous studies focused only on the mortality risks for heat waves or cold spells for certain time period not considering its temporal changes and increasing frequencies. This study investigated the change in risks of mortality from heat waves and cold spells over time, and estimated the temporal changes in mortality burden attributed to heat waves and cold spells in Korea and Japan. We collected time-series data covering mortality and weather variables from 53 communities in the two countries from 1992 to 2015. Two-stage time-series regression with a time-varying distributed lag model and meta-analysis was used to assess the impacts of heat waves and cold spells by period (1990s, 2000s, and 2010s). In total population, the risks of heat waves have decreased over time; however their mortality burden increased in the 2010s compared to the 2000s with increasing frequency. On the other hand, the risk and health burden of cold spells have increased over the decades. Our findings showed that the future mortality burden of heat waves and cold spells might not decrease, when considering their changes in risks and frequencies.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Average frequency of heat waves and cold spells increased in the 2010s in Korea and Japan. </LI> <LI> RRs of heat waves significantly decreased in total population. </LI> <LI> RRs of cold spells have significantly increased in all regions. </LI> <LI> Almost ARFs of heat waves and cold spells increased in the 2010s than 2000s. </LI> <LI> Health burden of heat waves and cold spells may not decrease in the near future. </LI> </UL> </P>

Technology Initiatives Derailed in U.S Early Education Schools : Should Leadership Redesign the Organizational Blueprint?

Michelle Lee Manganaro 육아정책연구소 2013 International Journal of Child Care and Education Vol.7 No.1

Where and when innovation occurs in the United States (U.S.) early education schools depends greatly on the congruency of long-standing workplace norms, access to resources, and the actual oversight of school leadership. Norms include many factors not the least of which is a work groups’ desire to improve. Resource access is controlled in large part by the government, both local and national. And finally, oversight of work methods and organizational communications is difficult for early education school leadership due to the high educator turnover rate, educator qualifications and traits, such as the emotional-intelligence of the work group, and the low rate of pay for the industry. Although government initiatives and individual school initiatives alike frequently focus on ‘quality service’, the workforce is simultaneously challenged with emotional intelligence factors. Leadership education of school leaders must collaborate a wide set of divergent perceptions of what constitutes quality service and which organizational communication will be enhanced by technology. The examination of data in a November 2012 survey focuses on what the educators perceive, what technology educators have access to, how educators are using technologies they have access to, and what educators view as connected among technologies and school quality.

Butyrate is known to play a significant role in energy metabolism and regulating genomic activities that influence rumen nutrition utilization and function. Thus, this study investigated the effects of an isolated butyrate-producing bacteria, Clostridium saccharobutylicum, in rumen butyrate production, fermentation parameters and microbial population in Holstein-Friesian cow. An isolated butyrate-producing bacterium from the ruminal fluid of a Holstein-Friesian cow was identified and characterized as Clostridium saccharobutylicum RNAL841125 using 16S rRNA gene sequencing and phylogenetic analyses. The bacterium was evaluated on its effects as supplement on in vitro rumen fermentation and microbial population. Supplementation with 10⁶ CFU/ml Clostridium saccharobutylicum increased (p < 0.05) microbial crude protein, butyrate and total volatile fatty acids concentration but had no significant effect on NH₃-N at 24 h incubation. Butyrate and total VFA concentrations were higher (p < 0.05) in supplementation with 10⁶ CFU/ml Clostridium saccharobutylicum compared with control, with no differences observed for total gas production, NH₃-N and propionate concentration. However, as the inclusion rate (CFU/ml) of C. saccharobutylicum was increased, reduction of rumen fermentation values was observed. Furthermore, butyrate-producing bacteria and Fibrobacter succinogenes population in the rumen increased in response with supplementation of C. saccharobutylicum, while no differences in the population in total bacteria, protozoa and fungi were observed among treatments. Overall, our study suggests that supplementation with 10⁶ CFU/ml C. saccharobutylicum has the potential to improve ruminal fermentation through increased concentrations of butyrate and total volatile fatty acid, and enhanced population of butyrate-producing bacteria and cellulolytic bacteria F. succinogenes.

Research Note : The Role of Glucosides on the Thermal Stability of Color Produced by Anthocyanins from Red Cabbage

( J. Michelle Lee ),( Moonsoo Jin ) 한국산업식품공학회 2015 산업 식품공학 Vol.19 No.2

Carbohydrate derivatives of cyanidin, a class of anthocyanin pigments, are major component of red cabbage, which is responsible for the characteristic reddish color. The color of cyanidin derivatives is quite stable against heat, and here we aimed to identify the chemical component of glucoside-derivatives of cyanidin which is responsible for the thermal stability. By comparing the thermal stability of color from unmodified cyanidin and cyanidin-3,5 diglucoside with the color of cyanidin derivatives from red cabbage, we found that the glucoside modification confers the thermal stability. We believe that our finding will contribute to the preparation of heat-resistant anthocyanin pigments for food coloring and other applications.

Suh Michelle J.,Lee Jihyun,Cho Wan-Ho,Jin In-Ki,Kong Tae Hoon,Oh Soo Hee,Lee Hyo-Jeong,Choi Seong Jun,Cha Dongchul,Park Kyung-Ho,Seo Young Jun 대한청각학회 2023 Journal of Audiology & Otology Vol.27 No.4

his study explores the internal standards for hearing tests and benefits of implementing international standard protocols, including the International Organization for Standardization (ISTO) and International Electrotechnical Commission (IEC), and discusses how ISO and IEC standards provide a framework for designing, calibrating, assessing hearing test instruments and methods, and exchanging and comparing data globally. ISO and IEC standards for hearing tests improve accuracy, reliability, and consistency of test results by applying standardized methods and environments. Moreover, they promote international harmonization and data interoperability, enabling information exchange and research collaboration. Those standards for hearing tests are beneficial but have challenges and limitations, such as variation in equipment and calibration, lag in updating standards, variation in implementation and compliance, and lack of coverage of clinical aspects, cultural diversity, and linguistic diversity. These affect the quality and interpretation of test results. Adapting ISO or IEC standards locally would improve their applicability and acceptability, while balancing customization and compatibility with global standards.

과학기술 혁신 시대의 신학

이윤경(Kim, Michelle Y. Lee) 수원가톨릭대학교 이성과신앙연구소 2018 이성과 신앙 Vol.65 No.-

오늘날 인류는 과학기술 혁신시대를 살고 있다. 물리학을 비롯하여 생물학에 이르기까지 현대 과학계의 패러다임 전환에 이어, 인공지능을 포함하는 정보기술과 생명기술 등을 이용해 인간의 몸과 뇌조차도 공학적으로 개조할 수 있는 시대가 왔다. 과연 현대인들은 이러한 놀라운 기술들을  올바로 사용할 수 있는가?  이제 우리는 역사상 어느 때 보다도 과학기술의 산물을 파괴적으로 사용할 수 있는 위험성에 광범위하게 노출되어있으나, 이에 대해 아는 것이 매우 제한적이다. 이 논문의 첫 번째 목적은 과학기술의 잠재적 파괴력의 위기와 당면한 생태적 위기를 하나의 복합적인 위기로 다루어 그 해결의 출발점을 제시해 줄 수 있는 통합적 세계관을 “사회적 위기와 생태적 위기는 하나의 복합적인 위기이다. 동전의 양면이다. 그 해결을 위해 반드시 필요한 것은 통합적 시각, 통합적 세계관이다.” 프란치스코 교황, 회칙 『찬미받으소서』, 138-162항. , “생명 지향적” 세계관을 도출하는 것을 목적으로 한다. “생명 지향적” 세계관은 현대의 과학적 이론들을 기반으로 하고 철학과 사회윤리를 포함한 학제간의 통찰을 참고한다. 이 논문의 두 번째 목적은 그리스도교 신앙의 핵심 가치들에 비추어 이러한 “생명 지향적”인 세계관의 신학적 의미를 고찰하는 것이다. We are living in an era of scientific and technological revolutions today. Scientific discoveries of the 20th century have radically transformed our views about nature. The 21st century’s sciences and technologies (e.g. brain science, artificial intelligence, information and life-science technologies) have shown their increasing power that could potentially alter the very fabric of our society, and even suggesting that they can provide tools to reengineer even the basic parameters of the human body and the brain. But how do we ensure that technological advancements benefit all? Do we understand what will happen if the advancements of these innovative technologies are left unchecked? Our insights regarding these questions are rather limited. The primary objective of this study is to develop a world view, which can be used to develop ethical guidelines that anticipate the risks of such powerful technologies. To develop such a world view, a “life-giving world view”, we take an interdisciplinary approach, integrating insights from contemporary sciences, ethics, philosophy and theology, and drawing wisdom from ecological vision. We suggest that this “life-giving world view” is morally and theologically coherent, and reflect on its theological meaning in light of the core values of the Christian faith.

본 연구는 ‘사회복지시설 안전관리 매뉴얼’의 텍스트를 언어네트워크 분석(Semantic Network Analysis) 기법을 통해 방대한 텍스트에 나타난 핵심 개념(키워드)들의 구성 관계에 대한 분석을 실시하였다. 매뉴얼에 나타난 하위 및 상위 SOP(Standard Operating Procedure)의 연결망 관계와 핵심 키워드의 연결망 관계의 중심성 분석을 시도하여 그 특성들과 개선점을 발견하는 것을 목적으로 한다. 연구결과 첫째, 사회복지시설 안전관리 매뉴얼은 SOP700에서 다루고 있는 자연재난 안전관리를 중심으로 하여 기술되어 있었다. 둘째, 사회복지시설 안전관리의 주요 행위자로 소방기관, 이용자, 관리자라는 키워드가 높은 중심성을 보이며 매뉴얼의 주요한 위치에 등장했다. 셋째, 예방과 대비라는 키워드가 중심성이 높아 재난 발생 전 단계와 관련한 절차에 강조점을 두고 있음을 알 수 있었다. 넷째, 사회복지시설 안전관리 매뉴얼은 이용자의 취약한 특성을 포함하여 제작되었음을 알 수 있었다. 이러한 결과를 바탕으로 사회복지시설의 안전관리 강화를 위한 매뉴얼의 개선점을 발견하여 논의하였다. This study has an aim of analyzing Social Welfare Facility Safety Management Manuals published by the Ministry of Health and Social Welfare in Korea using a semantic network analysis in order to identify the attributes of and relationships among keywords in SOP (Standard Operating Procedure) manuals. Firstly, natural disasters and fire had highest centrality in the manuals. Secondly, the main performers described in the manual were found to be fire station, clients and workers of the welfare facilities. Thirdly, regarding their ascribed duties, prevention and preparedness were at the center of the whole network, which means that the manual focuses on preventing remedies. Overall, the manual is believed to take into consideration the traits of clients and be written from their perspectives. A few discussions are presented based on these findings.
