Objective-We investigated the influence of social support on health, quality of life (QOL), and the risk of depression in elderly Korean people. Methods-This study was conducted as a part of the Korean Longitudinal Study on Health and Aging (KLoSHA). A total of 787 nondemented community-dwelling elderly aged 65 years or older were recruited and underwent clinical evaluations for dementia and psychiatric disorders conformed to Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease Clinical Assessment Battery (CERAD-K) and the Korean version of the Mini-International Neuropsychiatric Interview (MINI), respectively. Social support was assessed using the Medical Outcome Study Social Support Survey (MOS-SSS). Poor social support (PSS) was defined as having a MOS-SSS score below the 25th percentile of the entire sample. General health status was comprehensively evaluated using the modified Cumulative Illness Rating Scale (CIRS), the Korean version of the Geriatric Depression Scale (GDS-K), Mini-Mental Status Examination (MMSE-KC), Korean Activities of Daily Living (KADL), and Korean Instrumental Activities of Daily Living (KIADL). Healthrelated QOL was evaluated using the Short Form 36 (SF-36). Results-Low educational attainment and living alone were associated with PSS. Geriatric depression was more prevalent in the PSS group (OR=3.05, 95% CI=1.77-5.27) than in the normal social support (NSS) group. Among the various forms of social support, positive social interaction was significantly associated with risk of geriatric depression (OR=2.25, 95% CI=1.07-4.73). Although health-related QOL was lower in the PSS group than in the NSS group, the ADL and IADL scores of the subjects in the PSS group were better than those of the subjects in the NSS group. In the subjects with geriatric depression, PSS was associated with more severe depression, higher medical morbidity, and poor QOL. Conclusion-PSS had a negative influence on the general health status and QOL among community-dwelling elderly and was an independent risk factor of geriatric depression.

The Experience of Providing Older Adult Patients with Transitional Care from an Acute Care Hospital to Home in Cooperation with a Public Health Center

Shin Jinyoung,Han Seol-Heui,Choi Jaekyung,Kim Yoon-Sook,이종민 대한의학회 2020 Journal of Korean medical science Vol.35 No.39

Background: This study aimed to describe the experience of providing older adult patients with transitional care from an acute care hospital to home in cooperation with a public health center, in order to present the barriers to that care and suggest better organizational methods. Methods: This was a cross-sectional study to show the results of the Geriatric Screening for Care-10 (GSC-10) and outcomes of transitional care. Among 659 hospitalized patients aged 65 years or above who lived in an administrative district, forty-five subjects were enrolled between June 24, 2019 and January 23, 2020. Within 48 hours of admission, using the 10 areas of GSC-10, they were assessed for cognitive impairment, depression, polypharmacy (5 or more medications), functional mobility, dysphagia, malnutrition, pain, and incontinence, and were reassessed before discharge. The transitional care plan (containing the treatment summary, the results of the GSC-10 assessment, and the post-discharge plan) was forwarded to a representative of the public health center, who provided continued disease management and various health care services, such as chronic disease and frailty care, and physical rehabilitation. Results: Of all the participants, 64.4% had more than 1 GSC-10 concern. The most prevalent concerns were functional immobility (35.6%) and polypharmacy (22.2%). About 15.6% of the participants were readmitted to a nursing home or hospital. A total of 38 participants received the transitional care intervention. They received an average of 2.7 administered interventions. However, the rate of rejection was high (30.1%) and patients were visited an average of 16.5 days after discharge. Conclusion: Through our experience of providing transitional care from an acute care hospital to home in cooperation with a public health center, we expect that the transitional care suitable for the Korean medical situation could be established and successful.

Background/Aims: The clinical benefit of strict blood glucose-lowering therapy for patients with coronary artery disease (CAD) is still debated. We aimed to evaluate the long-term outcomes of patients with diabetes who under-went percutaneous coronary intervention (PCI), according to the mean hemoglobin A1c (HbA1c) level after PCI. Methods: We evaluated 675 diabetes patients with CAD treated with PCI. We categorized the study population into three groups based on the mean observed HbA1c levels during the follow-up duration, as follows: aggressive control (AC) group (HbA1c level < 6.5%, n = 148), moderate control (MC) group (HbA1c level ≥ 6.5% and < 7.0%, n = 138), and uncontrolled (UC) group (HbA1c level ≥ 7.0%, n = 389). The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCEs), defined as cardiac death, myocardial infarction, repeat target vessel revascularization, and stroke. Results: The mean HbA1c level of the AC group was significantly lower than that of the MC and UC groups (6.04% ± 0.36% vs. 6.74% ± 0.14% vs. 8.39% ± 1.20%, p < 0.001). The incidence of MACCEs was significantly lower in the AC group than in the MC and UC groups (16.0% vs. 24.3% vs. 26.3%, p = 0.010), mostly driven by the incidence of stroke (4.4% vs. 14.0% vs. 11.4%, p = 0.013). Multivariate Cox regression analysis showed that only the AC group was associated with a reduced rate of MACCEs (hazard ratio, 0.499; 95% confidence interval, 0.316 to 0.786; p = 0.004) com-pared with the UC group. Conclusions: Our study showed that intensive glycemic control (HbA1c level < 6.5%) is associated with improved clinical outcomes after PCI in patients with diabetes.

Jaekyung Kim,Young Shin Kim,Euy Sik Jeon 한국정밀공학회 2024 International Journal of Precision Engineering and Vol.11 No.2

According to a recent comprehensive study on window systems, windows account for approximately 60% of a building’s total energy loss. In this regard, much research is being conducted to reduce energy loss through windows, among them, vacuum glazing maximizes the insulation performance by sealing between two sheets of glass with a vacuum. In this study, proposes a novel strategy for fabricating vacuum glazing using microwave heating in vacuum pressure and direct glass edge sealing. By applying a process using microwaves, the energy used in the vacuum glazing fabrication process is minimized, and the structural strength of the vacuum glazing is improved by directly sealing the glass. In order to prevent arc discharge that can occur when microwaves are applied in vacuum pressure, microwave power was set as a variable, and heating experiments were conducted accordingly. The experiment enabled the analysis of the relationship between temperature and pressure change according to the power, and accordingly, a vacuum glass sample with direct sealing was fabricated. The fabricated vacuum glazing was tested for thermal transmittance (U-value) in single and double layers and confirmed to be 3.5 W/m2 K and 1.6 W/m2 K, respectively.

이사회의 독립성이 기업가치에 미치는 영향

김재경(Jaekyung Kim),신진영(Jhinyoung Shin) 한국증권학회 2016 한국증권학회지 Vol.45 No.4

본 연구는 사외이사의 사회적 연결(social tie)을 이용하여 이사회의 실질적 독립성을 측정하였고 이것이 기업가치에 미치는 영향을 실증적으로 분석하였다. 사외이사의 사회적 연결을 사외이사와 사내이사, 사외이사와 최대주주와의 관계로 나누어 살펴보았고 사회적 연결의 구체적인 점수 측정은 사회연결망 분석에서 사용되는 개념을 적용하였다. 분석결과에 따르면, 사외이사와 사내이사 간의 사회적 연결이 높아 이사회의 독립성이 저하되는 경우 기업가치에 부정적인 영향을 미치는 것으로 나타났다. 반면 사외이사와 최대주주 간의 사회적 연결이 높은 것과 기업가치와는 통계적으로 뚜렷한 관계가 존재하지 않는 것으로 나타났다. 이러한 본 연구의 결과는 이사회의 독립성 제고를 위해 도입된 우리나라의 사외이사제도의 개선의 필요성을 확인하였다는 점에서 의의를 가진다. 또한 이사회의 독립성을 사회연결망 분석에서 사용되는 기법을 이용해 측정한 점에서도 역시 중요한 의의를 가진다. This study empirically examines the effect of board independence on firm value by measuring social ties of outside directors with executive directors as well as controlling shareholder. The measurement of social ties of outside directors is deduced by adopting the concept in social network analysis. The results show that strong social ties between outside directors and executive directors reduces the level of the independence of board, and thereby results in a significant and negative effect on firm value. However, strong social ties between outside directors and the controlling shareholders have no significant relationship with the firm value. These empirical evidences suggest that outside director system of Korea which was intended to improve board’s independence should be reformed. Additionally, this study contributes to the application of different measures of board independence by adopting the technique of social network analysis.

Importance of Geriatric Syndrome Screening within 48 Hours of Hospitalization for Identifying Readmission Risk: A Retrospective Study in an Acute-Care Hospital

Jinyoung Shin,Seol-Heui Han,Jaekyung Choi,Yoon-Sook Kim,Jongmin Lee 대한노인병학회 2020 Annals of geriatric medicine and research Vol.24 No.2

Background: Given the association between geriatric syndrome and hospital readmission, we evaluated the suitability of geriatric syndrome screening for care (GSC) in identifying readmission risk and suggested the appropriate time for GSC. Methods: GSC considering cognitive impairment, depression, polypharmacy (five or more medications), functional mobility, dysphagia, malnutrition, pain, and incontinence was performed among 2,663 general ward inpatients aged 65 years or older within 48 hours after admission and again before discharge between November 2016 and October 2017. Each patient’s history of falls, pressure ulcers, potentially inappropriate medication use, and delirium was assessed at admission. Patients were divided into two groups on the basis of readmission within 1 year after the first admission. According to the screening period (at admission and before discharge) and in-hospital decline, we applied receiver operating characteristic curve analysis to compare the prevalence of clinical concerns between the readmission and no-readmission groups. We also used multiple logistic regression analysis to evaluate the risk of readmission according to the presence of geriatric syndrome and clinical outcomes. Results: The 782 readmitted patients (29.4%) showed a higher rate of poor GSC than those who were not readmitted. Polypharmacy at admission was significantly correlated with readmission risk (area under the receiver operating characteristic curve=0.602). Fall history (odds ratio [OR]=4.36; 95% confidence interval [CI], 2.36–8.05), urinary incontinence (OR=4.21; 95% CI, 3.28–5.39), and depressive mood (OR=3.88; 95% CI, 2.69–5.59) at admission were risk factors for readmission. Conclusion: GSC at admission was associated with readmission risk compared with GSC before discharge or monitoring for in-hospital decline.

여성의학과 의료 서비스디자인 개선 연구

신지연(Shin, Jiyoun),조재경(Cho, Jaekyung) 인제대학교 디자인연구소 2013 Journal of Integrated Design Research (JIDR) Vol.12 No.3

최근 사회 전반에 걸쳐 서비스 산업의 비중이 높아지면서 의료서비스와 관련해서도 보다 환자를 배려하는 질높은 서비스와 진일보한 의료 환경에 대한 요구가 있었다. 보건 의료 분야에서도 디자인과 의료 서비스의 접점을 찾아 문제를 해결하려는 움직임이 있었고 디자이너의 시각에서 역량을 발휘하여 의료서비스의 여러 문제를 해결하고자 하고자 하는 다양한 시도가 나타나게 되었다. 따라서 여성의학과 병원의 경우에도 미용 관련 산업이나 산후조리원, 레스토랑 또는 카페 등의 외식업과 연계하여 여성의 심리적, 행동적 특성을 고려한 서비스를 제공하는 의료시설이 늘어났으나 이와는 별개로 정작 여성의학과와 관련된 치료나 시술을 자유롭고 떳떳하게 받을 수 없는 환경에 놓인 미혼 여성에 대한 배려는 매우 미약하다. 오늘날 우리 사회 젊은 층의 성의식이나 태도는 급격히 변화하고 있다. 특히 개방된 성 의식과 문화의 유입으로 기성세대와는 달리 성에 대해 자유로운 가치관과 태도를 지닌 사람이 많아졌다. 그러나 피임 교육과 임신, 출산에 대한 사회적 안전장치에 대한 논의와 적절한 대안은 제시되지 않은 채 여전히 과거에 머물러 있다. 본 연구에서는 여성이 여성의학과 병원에 내원하여 진료를 받는 과정에서 발생하는 심리적 장애요인을 구체적으로 확인하기 위하여 관찰 및 심층 인터뷰를 수행한 후 서비스 이용 단계에 따라 환자 여정 맵을 제작하였다. 그 결과 환자가 서비스의 전 과정에 걸쳐 사생활의 침해에 따른 불편함을 느끼는 것을 확인 할 수 있었고 특히 다른 환자의 시선이 불편하게 느껴지거나 의료진이 환자에 대해 공감하고 배려하는 정도가 낮은 데서 오는 불쾌함을 토로한 환자가 많아 심리적인 장애 요인이 분명히 작용하고 있다는 것을 확인 할 수 있었다. 본 연구는 여성의 눈높이에서 진행되는 연구를 통해 임신 및 출산을 목적으로 병원을 방문하는 환자는 물론 전 연령의 여성 환자의 편의 향상에 그 궁극적 목적이 있다. 또한 디자이너의 활동 무대가 단지 제품이나 광고 등 상업적 이익 창출에만 머무르지 않고 보건의료 분야의 문제를 다루고 나아가서는 사회적 차원의 문제를 해결하는데 보다 표준화된 디자인 방법과 도구를 활용하여 기여함으로써 공공의 이익과 사회 전반에 걸친 서비스의 질적인 발전에 일조할 수 있을 것으로 사료된다. A variety of demands of high quality service for patients and advanced medical environments has been raised to medical services in along with the increasing proportion of service industry in the overall aspects of society. In the health and medical area, there was an attempt to solve problems by finding out a contact point between design and medical services, and also various attempts have been made to solve medical service problems from the perspective of designers. Accordingly, in case of obstetrics and gynecology, there are increasing number of medical facilities providing services reflecting women’s psychological and behavioral features in connection with beauty industry, postnatal care center and food service industry like restaurant and cafe. Besides, it is still very insufficient to consider single women who are not properly cared or treated in relation with obstetrics and gynecology. Social awareness on single women who had experiences in sexual discourse is still negative, and women suffering from diseases could not properly express their own disease which tends them to aggravate diseases. This study would like to examine various barriers in the use of actual services together with background in which patients would not use medical services in obstetrics and gynecology, and then attempts to find improvement measures to consider women by means of service designs. Through the study carried out from the perspective of women, this study aimed to improve convenience of all aged women as well as patients for pregnancy and child birth. And the activities of designers do not remain in commercial profits such as product or advertisement but could involve health and medical problems. Furthermore, it is also expected to contribute to quality development of services for public benefits and social benefits by providing standardized design method and tools to solve problems of social level.
