The purpose of the present study was to examine the severity of suicidal ideation of the older adults according to the amount of involvement in grandchild care. Data for this research were drawn from a cross-sectional study conducted on community-dwelling adults aged 65 years or older. The 922 participants were divided into three groups according to their involvement in grandchild care: 18.5% had provided daily care, 12.4% had provided occasional care, and 69.1% had never cared for their grandchildren. ANCOVA analysis showed that the scores for depression was significantly lower in the group which took care of their grandchildren occasionally compared to the other two groups. The scores for suicidal ideation was significantly higher in the group which had never taken care of their grandchildren compared to the other two groups. Current study suggests that grandparenting may have a positive effect on suicidal ideation of the older adults.

Objectives The aim of this study was to investigate the variables influencing acceptability and perception towards suicide among the elderly in Bucheon city, South Korea. Methods A total of 1099 elderly over 65 years old participated in this study. The subjects completed a self-questionnaire including their demographic characteristics, psychiatric characteristics, factor 1 and 4 of the Attitudes Towards Suicide-20, and Geriatric Depression Scale Short Form Korea Version. One-way analysis of variance was performed to identify the variables associated with the acceptability and perception towards suicide. Results As result of this study, the demographic characteristics (older age, lower education level, lower economic state, bereavement, divorce or separated marital status, and life without spouse) and psychiatric characteristics (psychiatric past history, treatment history, and suicidal attempt history) were found to be associated with a more acceptable attitude toward suicide. In addition, a lower education level, no psychiatric history, and no psychiatric treatment history influenced the lack of perception to suicide. Conclusion For public services to prevent suicide of the elderly population who lack spontaneity and accessibility to suicidal evaluations, it would be important to focus on the variables identified in this study for enhancing the effectiveness of the services.
Review of Genocidal Elements on the Human Rights Abuses in North Korea
Doeun Lee 이화여자대학교 통일학연구원 2016 Journal of peace and unification Vol.6 No.1
This article started from the question of whether the violations of human rights being carried out in North Korea so far are applicable to genocide. The paper examines the configurable requirements of genocide by four large elements: the objective groups, the extent of destruction, the specific types, and intent to destroy. As a result, the paper has found that the North Korean leadership commits genocide with the intent to destroy religious groups, mainly consisting of Christians and national groups including half-breed children. Considering the tendency of imposing the highest sentence in international courts when the case is determined as genocide, it seems to require active research on the possibilities of ruling the North Korean human rights situation as genocide.

In the human body, proteins secreted into peripheral blood vessels are known as the secretome, and they represent the physiological or pathological status of cells. The unique response of cells to toxin exposure can be confirmed via secretome analysis, which can be used to discover toxic mechanisms or exposure markers. Alpha-amanitin (α-AMA) is the most widely studied amatoxin and inhibits transcription and protein synthesis by directly interacting with RNA polymerase II. However, secretory proteins released during hepatic failure caused by α-AMA have not been fully characterized. In this study, we analyzed the secretome of α-AMA-treated Huh-7 cells and mice using a comparative proteomics technique. Overall, 1440 and 208 proteins were quantified in cell media and mouse serum, respectively. Based on the bioinformatics results for the commonly downregulated proteins in cell media and mouse serum, we identified complement component 3 (C3) as a marker for α-AMA-induced hepatotoxicity. Through western blot in cell secretome and C3 ELISA assays in mouse serum, we validated α-AMA-induced downregulation of C3. In conclusion, using comparative proteomics and molecular biology techniques, we found that α-AMA-induced hepatotoxicity reduced C3 levels in the secretome. We expect that this study will aid in identifying new toxic mechanisms, therapeutic targets, and exposure markers of α-AMA-induced hepatotoxicity.
전장연 지하철 투쟁 관련 담론의 의미와 주체구성 방식 연구 : 조선일보와 한겨레신문 기사를 중심으로
이도은(DoEun Lee) 한국장애인재단 2023 장애의 재해석 Vol.2023 No.-
본 연구는 미셀 페쇠(Michel Pêcheux)의 담론분석 틀을 이용하여 전장연의 〈지하철 출근길 탑니다〉 지하철 투쟁과 관련하여 조선일보와 한겨레신문이 생산하는 담론의 의미구성 방식과 주체구성 방식을 분석하고자 하였다. 분석 결과, 조선일보와 한겨레신문 모두 담론의 의미를 구성하기 위해 이데올로기적 기제들을 사용하고 있음을 확인하였다. 담론의 외적 개입인 선구성 기제를 통해 현실을 선구성하고 당연한 것으로 전제하였으며, 담론의 내적 개입인 절합 기제를 통해 선구성된 주절의 의미를 뒷받침하는 효과를 주었다. 또한 이데올로기의 주체구성 방식인 호명 테제를 ‘우리(us)-그들(them)’ 구조를 적용해 분석한 결과, 조선일보와 한겨레신문은 착한 주체와 나쁜 주체로 구성 및 호명함으로써 이데올로기적 주체를 구성하였다. 한편 한겨레신문은 전장연을 나쁜 주체로 호명하는 이데올로기에 대항하고 새로운 실천유형을 생성하는 역동일시된 주체들을 구성하고 있음을 발견하였다. The purpose of this study is to analyze the meaning and subject composition of discourse by the Chosun and Hankyoreh newspapers in relation to the subway ride action conducted by Solidarity Against Disability Discrimination(SADD) based on Michel Pêcheuxs discourse analysis framework. As a result of the analysis, it was confirmed that both the Chosun and Hankyoreh newspapers used two mechanisms which are the pre-constructive and articulation for discoursive constitution of meaning and subject. In addition, as a result of analyzing the interpellation by applying the us-them structure, the Chosun and Hankyoreh newspapers formed ideological subjects by composing and calling a good and bad subject. It was found that Hankyoreh newspaper constructed the power-resistance dynamic against the ideology calling SADD as a bad subject and created a new type of practice.
Electroforming-less and multi-level resistive switching characteristics in tungsten oxide thin film
Lee, Seunghyup,Yun, Ki Hoon,Kim, Doeun Elsevier 2019 THIN SOLID FILMS - Vol.674 No.-
<P><B>Abstract</B></P> <P>Thermally grown tungsten oxide (WOx) thin film on a tungsten electrode is studied as a potential memristor material. Due to the dislocation formation inside the film, the device could present stable memristive characteristics without electroforming process. In this research, the opportunity of applying the WOx memristor to the multi-level resistive switching behavior based multi-level memory or artificial synaptic device was presented. In particular, the flexibility of the device shows the possibility of a future flexible memory device. Interpreting the memristive characteristics, the resistance switching mechanism was discussed based on the valance change at the device structure interface. Based on the simple fabrication process and electroforming-less operation, the results present the possibility of applying WOx based memristors in current electronic devices at an early stage. This work reveals a useful proposal of WOx based memristors for emerging device applications.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Memristive characteristics studies of thermally grown tungsten oxide thin film. </LI> <LI> Investigation of electroforming-less, multi-level resistive switching. </LI> <LI> Flexible memristive characteristics of tungsten oxide thin film device. </LI> <LI> Interpretation of interfacial valance change based resistive switching behavior. </LI> </UL> </P>
