Previous research has shown that the flow of patients around departments of geriatric medicine and ex-patients in the community may be-modelled by the application of a mixed-exponential distribution. In this proper we considered a ave-compartment model using a continuous-time Markov process to describe the flow of patients. Using a M/ph/c queuing model, we present a way of optimizing the number of beds in order to maintain an acceptable delay probability a sufficiently low level. Finally, we constructed a Java computer simulation, using data from St George's Hospital, London.

Objectives: This study was undertaken by the department of Korean neuropsychiatry, to evaluate the effects of M&L psychotherapy and Korean Medical Treatments on hospitalized North Korean defectors.Methods: We treated two patients with indigenous Korean medical therapies (acupuncture and herb-medicine) and M&L psychotherapy. Beck's Depression Inventory (BDI), Insomnia Severity Index (ISI), Geriatric Depression Scale (GDS), Mini-mental state examination Korean Version (MMSE-K), and Visual Analogue Scale (VAS) were used to evaluate the patients.Results: Following observations were made after treatments. Case 1: the patient had significant improvement in Beck's Depression Inventory (BDI), Insomnia Severity Index (ISI), and Visual Analogue Scale (VAS). Case 2: similar improvements were observed. Here, the patient had undergone Geriatric Depression Scale (GDS), Mini-mental state examination Korean Version (MMSE-K), and Visual Analogue Scale (VAS). In addition, noticeable improvement was observed in other accompanying symptoms.Conclusions: These results suggest that M&L Psychotherapy and Korean medical treatments might be effective for treating the psychiatric and physical symptoms of hospitalized North Korean Defectors.

본 연구는 외국에서 이미 연구들이 진행되고 있는 노인간호 동물로봇과 관련하여 한국 노인을 위한 동물 로봇을 개발하는 경우 어떠한 속성을 포함하여야 할지 그 내용을 확인하고자 수행되었다. 이를 위해 재가노인 간호전문가와 시설노인전문가 13인을 대상으로 Focus group interview를 수행하였다. 자료수집은 2014년 8월 부터 12월 까지 이루어졌으며 2개 그룹으로 나누어 2명의 연구자가 인터뷰를 진행하고 인터뷰 결과에 대한 디브리핑과 필사자료를 바탕으로 내용분석을 통해 결과를 도출하였다. 그 결과 세 가지 주제 (효용성 인정, 모양, 기능)가 확인되었다. 구체적으로는 1인 가구 노인에 대한 효용성이 인정되었고, 모양과 크기는 우리나라 노인들에게 친숙한 강아지 모양, 그리고 다루기 용이한 3kg내외의 무게가 적합한 것으로 나타났다. 기능은 노인 뿐 아니라 가족들의 요구에도 부응할 수 있어야 하며 이를 위해 두 가지 핵심 기능 즉 상호작용 기능과 모니터링 기능이 필요한 것으로 드러났다. 본 연구의 결과 드러난 노인 간호 동물로봇의 요소들은 앞으로 노인을 대상으로 하여 확인할 필요가 있다. 또한 후속 연구들에서는 보다 구체적으로 각 주제별로의 컨텐츠에 대해 탐구할 필요가 있다.

Schizandra chinensis (S. chinensis) exhibits a harmless, 'adaptogen-type' effect leading to improvements in mental performance and learning efficacy in brain. Activated microglia contributes to neuronal injury by releasing neurotoxic products, which make it important to regulate microglial activation to prevent further cytological as well as functional brain damage. However, the effect of S. chinensis on microglial activation has not been examined yet. We have investigated the effects of four compounds (Gomisin A, Gomisin N, Schizandrin and Schizandrol A) from S. chinensis on lipopolysaccharide (LPS)-induced microglial activation. In this study, BV2 microglial cells were activated with LPS and the microglial activation was assessed by up-regulation of activation markers such as nitric oxide (NO), reactive oxygen species (ROS), and matrix metalloproteinase-9 (MMP-9). The results showed that all four compounds significantly reduced the intracellular level of ROS, the release of NO and MMP-9 as well as LPS-induced phosphorylation of ERK1/2. These results strongly suggested that S. chinensis may be useful to modulate inflammation-mediated brain damage by regulating microglial activation.

A research project, the "Construction of Frailty Cohort for Elderly and Intervention Study," funded by the Ministry of Health and Welfare, has been ongoing since December 2015. The Korean Frailty and Aging Cohort Study (KFACS) aims to identify risk factors for adverse outcomes associated with frailty in community-dwelling older adults, as well as means of prevention. KFACS is a multicenter, longitudinal study, with the baseline survey being conducted in 2016-2017. The sample (n=3,000) consists of those aged 70-84 years, stratified by age and gender, recruited from urban and rural regions nationwide. An in-person interview and health examination are performed every 2 years. This project is also conducting many intervention studies. Project interventions focus on nutrition and exercise. The nutritional intervention study compares the effects of 1.2 g/kg versus 1.5 g/kg daily protein intake on sarcopenia and frailty in older Koreans. The exercise trial examines the effectiveness of an information and communication technology-based program in preventing or reducing frailty.

Background: Elderly patients visiting pain clinic may be at greater risk of misunderstanding the explanation because of age-related cognitive decline. Video instruction may provide a consistent from of teaching in a visual and realistic manner. We evaluated the effect of educational video on the patient understanding and satisfaction in a group of geriatric patients visiting pain clinic. Methods: Ninety two patients aged more than 60 years old who were scheduled for transforaminal epidural block were recruited. After exposure to either video or paper instruction process, each patient was asked 5-item comprehension questions, overall satisfaction and preference question. During follow-up period, number of outpatient referral-line call for further explanation was counted. Results: We observed significantly better comprehension in the video education compared with paper instruction (P < 0.001). Patient satisfaction was also higher in the video group (P = 0.015), and patients visiting pain clinic were more preferred video instruction (P < 0.001). Proportion of referral-line call for further explanation were similar (P = 0.302). Conclusions: Video approach to instruction process before consent improves treatment comprehension in geriatric patient visiting pain clinic.

최근 노인인구의 급속한 증가로 인하여 정신과에서 노인에 대한 자문의 중요성이 확대되고 있다. 따라서 임상에서의 노인에 대한 정신과 자문의 특징과 지침에 대한 이해가 필요하다. 타과적 질환을 갖는 노인에 대한 정신과적 자문은 다른 연령층과는 다른 특성을 갖는다. 노화에 따른 장기 기능의 변화와 약동학 및 약력학의 변화에 대한 숙지가 노인에 대한 정신약물학적 접근에 매우 필수적이다. 타 연령층에 비해 노인에 대한 정신과적 자문은 상대적으로 적은 것으로 조사되었으나 실제 정신과적 자문이 노인질환의 재원기간이나 기타 사망률 등을 낮출 수 있음을 고려할 때, 노인에 대한 자문을 저해하는 요인들을 분석하고 교정하는 것이 매우 필요하다.
