Purpose: The phenomenon related to management when thee is a change in the condition of residents at risk in nursing homes is of interest to researchers in nursing. This study was conducted to clarify and to conceptualize the factors of management related to emergent circumstances in nursing homes though nurses' perceptions on these phenomena. Methods: A qualitative study method using in-depth interviews with 30 experienced nurses (mean age=46.6 yrs.; mean work experience in hospital=13.3 yrs; mean work experience in nursing home=3.9 yrs.) from three nursing homes in South Korea was used. Results: This study identified categories with sub-categories of each category related to managements of changes in the condition of the residents at risk in nursing homes: nurses' modes of identifying the changes in the condition of the residents, nurses' perceived directions on managing the condition which resulted in the changes in the residents at risk, and nurses' perceived strategies and barriers in managing changes in the condition of the residents at risk. Conclusion: Through this study, characteristics in managing residents’ emergent circumstances in nursing homes, and how nurses made decisions in the management of signs and symptoms indicating emergent situations are identified.

임세현,박기철 한국인더스트리얼디자인학회 2023 산업디자인학연구 Vol.17 No.4

연구배경 본 연구는 전기차 사용자들이 충전 과정에서 느끼는 문제점을 개선하여, 총체적인 사용자 충전 만족도를 향상시키기 위한 EV충전부 디자인 및 서비스 제안을 목적으로 한다. 연구방법 전기차 충전 현황 파악을 위한 문헌 정보 조사와국내외 다양한 사례 조사를 통해 대면 인터뷰와 온라인 설문조사를 진행하여 문제점을 파악하였다. 인터뷰 대상자는 전기자동차 충전소를 방문하여 충전을 진행하고 있는 사용자들과 전기차 보유자들로 구성된 온라인 동호회를 대상으로 시행하였다. 이를 통해 도출된 결과물로 차량 충전부 디자인 및 서비스를 제안하고 사용자 테스트를 진행하여 유용성 및 만족도를 알아보았다. 연구결과 문헌조사 기반의 선행연구를 통해 현재 높은 이용률을 보이는 실외 충전을 중점으로 문제점들을 발견하였고 이러한 배경으로 대면 인터뷰를 진행한 후 기상 환경, 어두운 환경, 충전 실패에 대한 심리적 불안감을 주 문제점으로 도출하였다. 이에 충전부를 외부 환경으로부터 보호해 주는 충전도어와 사용자 중심의 반응형 조명을 포함한 충전부 디자인을 제안하였으며, 충전 실패의 우려를 줄이기 위해 모바일 커넥티드 서비스도 함께 제시하였다. 결론 제안하는 차량의 충전부 디자인과 모니터링 서비스는 사용자의 심리적 불안감 해소와 더불어 충전 도중 발생할 수 있는 안전 문제나 충전 장치의 손상을 예방할 수 있도록 하였다. 현재 활발히 이루어지고 있는 전기차 충전 관련 기술의 발전과 함께 차량의 충전부와 같은 디자인 영역에서 후속 연구가 지속된다면 충전 환경의 문제를 극복하고 전기차 시장의 활성화로 이어질 수 있을 것을 기대한다. Background This study aims to propose EV charging equipment and services to enhance overall user charging satisfaction by addressing the issues experienced by electric vehicle users during the charging processMethods Through a literature review and international case studies, this study assessed electric vehicle charging. Face-to-face interviews and online surveys were conducted with users and online community members to identify issues. Proposals for vehicle charging port and services were made based on insights, followed by usability and satisfaction testing. Results Based on literature research, this study prioritized outdoor charging, identifying key issues through interviews. Major concerns included weather conditions, low lighting, and psychological anxiety from charging failures. Proposals encompass charging port design, including protective charging doors and adaptive lighting for interactions. Additionally, a mobile service was suggested to mitigate charging concerns. Conclusion The proposed vehicle charging port design and monitoring service aim to alleviate user psychological anxiety and prevent safety issues and damage to the charging device during charging. With the ongoing development of EV charging-related technologies, continued research in design areas like charging port is expected to address charging environment challenges and contribute to the activation of the electric vehicle market.

Objectives : Gleditsiae Spina has the effects of expelling toxins, draining pus, invigorating blood and resolving abscesses. Some clinicians apply the herb for patients suffering from cancer. However, its anti-cancer activities are not well understood. In the present study, anti-tumor agents from Gleditsiae Spina were purified. Methods : The viability of the PC-3 cell line was determined using MTT assay, and the induction of apoptosis by Gleditsiae Spina extract in PC-3 cells was measured by Annexin-V/propidium iodide double staining assay detected by flow cytometry. TLC and HPLC analysis were used to separate and identify the anti-cancer agents. Results : Treatment of the extract resulted in significant decreased cell viability of PC-3 cells in a dose- and time-dependent manner. Dose-dependent apoptotic cell death was also measured by flow cytometry analysis. The anti-cancer agents were successfully separated and identified by using TLC and HPLC analysis and the most potential agent among them was separated from EtOAC fraction. Conclusions : These results might be applied in developing new drugs from natural resources like Korean traditional medicine, and also support the clinical usefulness of herbal medicine.

Objectives : The pathophysiology of ICH is not fully understood, therefore, the fundamental therapeutic strategies for ICH also not well inspected either. The genetic profile for the effect of Carthami Flos extract on cerebral hemorrhage in rat brain tissue was measured using microarray technique. Genes displaying expressional change on brain damage were selected and the functional analysis on these genes was conducted. Methods : Rats were placed in a stereotaxic frame after intraperitoneal injection of chloralhydrate, and ICH was induced by injection of collagenase type IV and Carthami Flos extract was administered orally. The molecular profile of cerebral hemorrhage in rat brain tissue was measured using microarray technique to identify up- or down- regulated genes in brain tissue. Results : Upon treatment with Carthami Flos extract on the rat having brain damage, many genes show expressional change. The pattern of gene expressional change can be classified into 8 classes in which two types of classes were composed of recovered genes from up or down-regulation by brain damage, respectively. Conclusions : Further analysis using protein interaction database identified some key molecules that can be used for elucidation of therapeutical mechanism of Carthami Flos extract in future.

임세현 한국융합학회 2021 한국융합학회논문지 Vol.12 No.2

국내 경도인지장애 노인의 약 10%는 매년 알츠하이머병이나 다른 치매로 이환된다. 이를 예방하기 위한 중재는 다양하게 수행되었으나, 이에 대한 근거의 통합은 시도되지 않았다. 이에 본 연구는 체계적인 문헌 고찰을 통해 경도인 지장애 환자를 위한 인지 기반 중재와 그 효과를 알아보고자 수행되었다. 문헌의 검색은 2010년부터 2020년 9월까지 학술연구정보서비스(Riss)와 KoreaMed를 활용하였다. 문헌의 선택 및 배제 과정을 거쳐 최종 12편이 선정되었으며, 비동등성 대조군 전후 유사 실험연구가 7편으로 가장 많았다. 본 연구의 분석 결과, 경도인지장애 노인을 위한 인지 기반 중재는 인지기능과 우울, 신체 건강 상태, 자아존중감, 운동 시·지각 검사, 생활 만족도, 자기효능감, 뇌파, 삶의 질, 의사소통과 상호작용기술평가 등에 긍정적인 영향을 주는 것으로 나타났다. 본 연구 결과를 토대로 경도인지장애 노인을 위한 중재 프로그램의 효과를 검증하기 위한 반복 연구를 제언한다. It is important to prevent progression of mild cognitive impairment (MCI) to Alzheimer's disease or other dementia. This study was conducted to investigate cognitive-based intervention and its effectiveness for the older patients with MCI through systematic review. Data search was conducted in September 2020, using the Korea Research Information Service (Riss) and KoreaMed. After selection of literatures according to the predefined inclusion criteria, a total of 12 articles were included. It is revealed that the cognitive-based intervention for the older adults with MCI was found to have a positive effect on the various factors including cognitive function, depression, physical health status, quality of life, and communication. However, it is difficult to draw a definite conclusion due to the various intervention strategies and instruments used. Thus, based on the results of this study, we suggest more studies to verify the effectiveness of such programs.

Objective : Banhahubak-tang is indicated for globus hystericus, marked by a subjective sensation as if something stuffed in the throat, chest distress, cough or vomiting, greasy whitish, taut and smooth pulse. In this study, the effects of Banhahubak-Tang extract (BHTe) were tested for anti-stress action. Methods : BHTe was extracted by pure water using electronic extractor and then fed to ICR male mice (20±2g) orally with the dose of 100㎎/㎏/day for five days. Mice were exposed to sociopsychological stress by restraining and seeing foot shock stressed mice for one hour for five days. Results : BHTe administered group showed a tendency of decreasing of serum corticosterone secretion when compared with control group, and BHTe administration also significantly up-regulated noradrenaline secretions in the dorsal cortex of brain. Lipid peroxidation of the brain tissues of mice were tested by measuring malondialdehyde, but BHTe showed no significant change. The elevated plus-maze test was designed to detect the effect of anxiolytic drugs, and BHTe administered group showed a significant increase of latency time. Conclusions : These results suggest that BHTe can effectively rid the psychological stress and it`s related diseases.
