Bipolar disorder in old age is a growing public health problem. We reviewed the epidemiology, clinical characteristics, course, cormobidity, and treatment of bipolar disorder in old age with special focus on comparing with younger patients. Most available date is gleaned from retrospective chart reviews and cohort studies. Many of these reviews have been targeted toward the clinician, and they have relied heavily on extrapolating data from other psychiatric disorders in late life or younger people with bipolar disorder. But, at present, there are more gaps in empirical knowledge than there answer, and greater research on bipolar disorder in older people will assist in enhancing services to this group as well as inform research on bipolar disorder across the life span.

The frequent comorbidity of anxiety and depression, particularly among elderly, is widely recognized by clinicians, but the debate continues as to whether the combined diagnostic designation is merited. There remains a group of patients with depression and anxiety symptoms who are not well classifyed. This article reviews the debate over anxious depression, generalized anxiety disroder in patients with major depressive disorder, mixed anxiety-depressive disorder, and reviews anxiety symptoms in elderly patients with depression. Comorbid anxiety symptoms are associated with a more severe presentation of depressive illness, including greater suicidality. Most antidepressant treatment studies in the elderly have found poorer treatment outcomes in those with comorbid anxiety (including delayed or diminished response and increased likelihood of dropout from treatment). Since comorbid anxiety affect clincal course and prognosis, and may worsen long-term disability in late life depression, considerably more research in this field is needed.

A number of studies have looked at depression and associated cognitive impairment. The term depressive pseudodementia has proved to be a popular clinical concept. Despite the improvement following treatment of depression, the baseline level of cognitive impairment in older depressive patients remained impaired, mostly. These patients would be likely at high risk of developing progressive dementia. Depressive symptoms and cognitive decline would be different phenotypes result from neurodegeneration of pathophysiology for dementia. Depression in elderly patients, especially late-onset appears to be a strong predictor of dementia. No more concept of pseudodementia, older patients with depressive symptoms combined cognitive impairment should probably have full dementia screenings, comprehensive cognitive testing and ongoing monitoring of their cognitive function.

Objective: This study aimed to assess the effectiveness of a balance training program in improving balance and functional independence to reduce fall risks among community-dwelling elders. Design: A multi-center randomized controlled trialMethods: A total of 66participants were randomly assigned to a balance training group or a control group. The balance training program, conducted three times a week for 32 weeks, included warm-up exercises, main balance training exercises, and cooldown stretch exercises. Outcome measures included the Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), and Modified Barthel Index (MBI). Results: The balance training group demonstrated significant improvements in all outcome measures, indicating enhanced balance, improved functional mobility, and increased independence in activities of daily living. In contrast, the control group showed only slight improvements in BBS, TUGT and MBI scores. Conclusions: These findings provide evidence supporting the effectiveness of balance training programs in reducing fall risk and promoting health and wellbeing among community-dwelling elders. Future research should aim to refine the design of these programs and assess the sustainability of the observed improvements.

마이크로스케일에 머무는 기존 전기화학 측정법의 분해능 한계를 극복하기 위해 최근 여러 새로운 전기화학 기술이 시도되고 있다. 특히 단일 나노입자의 impact 연구 및 전기화학 이미징 기술의 개발이 활발히 이루어지고 있다. X-ray, 형광, 분광학 등 다른 방식의 도구를 이용하여 전기화학 이미징을 수행하는 간접적인 방식과 패러데이전류 및 전도도 전류를 직접적으로 측정하는 이미징 방식이 모두 연구되고 있다. 특히 이 중에서 나노피펫 기반의 주사 전기화학 프로브 현미경은 상대적으로 높은 분해능 및 다른 도구와의 용이한 결합으로 최근 주목받고 있으며, 이를 이용하여 다양한 전극 물질에 대해 단일 나노구조체 수준에서 전기화학 거동을 관찰할 수 있게 되었다. 본 기고 문에서는 여러 전기화학 이미징 기술의 원리, 현황, 미래에 대해서 소개하고자 한다.

To improve the high frequency noise from Power Steering, we analyzed it by Taguchi method. We could get the optimized solutions by finding the level which was influenced by each parameter of noise. Concretely we confirmed if it was improved or not through the vehicle test.

Avariety of symptoms can occur following traumatic brain injury(TBI) or other types of acquired brain injury. These symptoms can include problems with short-term memory, attention, planning, problem solving, impulsivity, disinhibition, poor motivation, and other behavioral and cognitive deficit. These symptoms may respond to certain drugs, such as dopaminergic agents. Amantadine may protect patients from secondary neuronal damage after brain injury as a effect of NMDA receptor antagonists and may improve functioning of brain-injured patients as a dopaminergic agonist. Clinically, based on current evidence, amantadine may provide a potentially effective, safe, and inexpensive option for treating the cognitive, mood, and behavioral disorders of individuals with brain injury. The rationales for using amantadine are discussed, and pertinent literatures are reviewed.

본 연구는 한반도 연안 해역에서 발생할 수 있는 다양한 작전유형을 바탕으로 소형 고속 함정의 적정 소요를 산출하기 위한 방법론적 접근이다. 이 연구방법은 운용 해역을 단위 경비구역으로 구분하고 구역할당 모형과 군집화 모형 등을 활용하였다. 이는 지금까지 작전 운용 장비의 적정 소요 산정시 선형기법등을 여러 가지 다양한 방법을 통해 검증해온 방법과는 달리, 최적화 기법을 활용한 작전 함정의 소요를 모델링하는 방법을 채택하였다. 이러한 경비구역에서 임무수행이 가능한 소형 고속 함정의 적정 소요는 "소요 최적화 프로세스"를 거쳐 소위 "하이브리드 적정 소요 모형"에 의하여 적정성을 산출, 검증하는 모델링 방법으로 제시하고자 한다. This paper deals with achieving the optimal quantity of required PKMs to cover the coastal areas divided into the proper size of sectors, and then using Set Cover Model, Clustered Model, etc. It is optimized via "Requirement Optimization Process" to allocate PKMs reasonably which is considered as conducting mission deployment sectors. This "Hybrid Proper Requirement Model" accommodating the optimization process is introduced and testified by examining a requirement problem.
