This study reviewed the present state and differences of rehabilitation programs of the gambling addiction by comparing with other psychiatric disorder(including psychotic disability and alcohol addiction). This study also intended to suggest necessities, meanings and inherent fields of the rehabilitation in gambling addiction. First of all, the government and a few gambling industries run clinic centers for gamblers and their families, but have been lacked rehabilitation services for social comeback and adaptation or devaluated rehabilitation services than therapies. Gambling addict didn't have impairments of the cognitive function and their daily abilities was better than any other psychiatric disorders. But Damage of social role or function of gambling addiction was severe. And it is caused by nonadaptive nature of gambling behavior, personality/emotional change through gambling addiction process, and previous personality problem etc. There are many severe failure of social role and its attendant bankrupcy, family's problems and social poverty in gambling addiction, Therefore, important fields in the rehabilitation of gambling addiction should be services for basic social comeback support service, credit recovery support, monetary management, support of rehabilitation of family and vocational rehabilitation. Finally, the significance and critical points of the current study has been discussed as well.

What is the semantic function of visual image in Contemporary art? This article proposes that representation is semantically still important in post-modernism as well as in modernism. The semantic function of representation has been changed by keeping pace with times. In modernism the 'outer representation' changed to 'inner representation', and in postmodernism the 'inner representation' changed to 'metaphorical representation'. The 'outer representation' means that image indicates a certain object or subject as the classical realism. In this case, the meaning of image is subordinate to an object, and a one-to-one correspond existed between the image and the object. Because this 'outer representation' is focused on an object but subject's intention, the indicative function of meaning is definite and singular. The 'inner representation' means that image exposes the fundamentals or process of an object. In this case, the meaning of image resolves itself into an absolute fundamental, and one-to-many correspond existed between the image and the object. Because this 'inner representation' is focused on essence and substance but an external form, the indicative function of meaning is inclusive and general. The 'metaphorical representation' means that image critically relates social constraint and condition as metaphor and allegory. In this case, the meaning of image is not subordinate to an object and a subject, and the image and the object indicate interactively. Because this 'metaphorical representation' is focused on interaction between subject, object, and interpreter, the indicative function of meaning is differant and ecological. This article focused on the representation because I believe that continuous thinking of totality can be opened by cognitive mapping, even though we never understand the world totally in the chaotic post modern age.

Falls are a leading cause of injury, disability and death among people older than 65. Even without injury, falls cause a loss of confidence that results in reduced physical activity, increased dependency and social withdrawal. Fall prevention in the eldery people is a multifaced task that includes both the identification of risk factors and their modification strategies. Fall risk factors have been identified as both intrinsic and extrinsic. Intrinsic factors are those related to the physical and cognitive function of the person. Extrinsic factors are those which are included in the environmental hazards of everyday life. Combinations of interventions aimed at modifying both intrinsic and extrinsic risk factors can result in significant fall prevention in the geriatric population. This article selectively reviews the literature reporting exercise intervention to improve strength, balance and mobility.

Tensor with missing or incomplete values is a ubiquitous problem in various fields such as biomedical signal processing, image processing, and social network analysis. In this paper, we considered how to reconstruct a dataset with missing values by using tensor form which is called tensor completion process. We applied Tucker factorization to solve tensor completion which was built base on optimization problem. We formulated the optimization objective function using components of Tucker model after decomposing. The weighted least square matric contained only known values of the tensor with low rank in its modes. A first order optimization method, namely Nonlinear Conjugated Gradient, was applied to solve the optimization problem. We demonstrated the effectiveness of the proposed method in EEG signals with about 70% missing entries compared to other algorithms. The relative error was proposed to compare the difference between original tensor and the process output.

This paper proposes an improved particle swarm optimization named PSO with Controllable Random Exploration Velocity (PSO-CREV) behaving an additional exploration behavior. Different from other improvements on PSO, the updating principle of PSO-CREV is constructed in terms of stochastic approximation diagram. Hence a stochastic velocity independent on cognitive and social components of PSO can be added to the updating principle, so that particles have strong exploration ability than those of conventional PSO. The conditions and main behaviors of PSO-CREV are described. Two properties in terms of "divergence before convergence" and "controllable exploration behavior" are presented, which promote the performance of PSO-CREV. An experimental method based on a complex test function is proposed by which the proper parameters of PSO-CREV used in practice are figured out, which guarantees the high exploration ability, as well as the convergence rate is concerned. The benchmarks and applications on FCRNN training verify the improvements brought by PSO-CREV.

Sleep disorders are relatively common occurrence after traumatic brain injury. Sleep disturbances often resulted in difficulties in sleep onset and sleep maintenance, nonrestorative after sleep, poor daytime performances and poor individual sense of wellbeing. Unfortunately, there has been minimal attention paid to this common and disabling sequela of brain injury. Better undertanding about problem, pathophysiology and treatment of sleep disorder after traumatic brain injury will improve the cognitive function, social adjustment and rehabilitation for injured patients. Also it may be helpful to reduce traumatic brain injury in patients with sleep apnea.

Purpose: Respite care is not a discrete intervention, but encompasses a range of services. This research was conducted to clarify the phenomenon of respite care for family caregivers of elders with dementia from a nursing perspective. Method: The Hybrid Model of concept development was applied to clarify the concept of respite care for family caregivers of elders with dementia. The study was conducted in the following three steps, theoretical phase, fieldwork phase, and final analytic phase. Results: The definition of respite care for family caregivers of elders with dementia was delineated through integration of data analyses in theoretical and fieldwork phase, and has three dimensions; tailored supports for caregivers, tailored supports based on physical and cognitive function of elders with dementia and community interventions related to family care function. Conclusion: Through this study, the concept of respite care for family caregivers of elders with dementia is clarified and reformulated as nursing practice phenomena in the Korean context, which indicates ways to develop caring practice forms for a family living with an elder with dementia in a community setting.

A changed image that they feel through makeup manipulates impression by linking with cultural standards and will be able to direct a variety of makeup images. Makeup in modern society has been expanding into the area of prevention of diseases and health of skin due to the development of cosmetics and has beautifully changed a face into a someone else's face due to the development of makeup technique. Also, assuming that motivation of makeup act of men and women is related to sexual instincts, I tried to analyze what kind of association the gender roles and the function of makeup required by the society has with age and regional and social background. In particular, I tried to explain that makeup act of men not only represents cognitive change of gender roles that have been perceived differently in modern society but has been adopted by men for the pure purpose in a socially equitable competition.

Purpose: This study was conducted to examine the effect of multidimensional program on cognition, physical function and depression among institutionalized elderly and the relationship between study variables and resident's characteristics and health related variables. Method: This study involved a one group pre and post test, comparison of variables over a 12 month period. To investigate this research question, data of 114 residents of a nursing home were analyzed. Results: There was statistically significant difference in MMSE-K (t=-2.63, p=.010), ADL (t=-2.85, p=.005), and depression (t=4.66, p=.000) before and after program participation. Conclusion: These results indicate that, for a year their regular involvement in a broad spectrum of multidimensional program activities can improve in cognitive, physical and emotional perspectives, but the level of IADL decreased significantly (t=-6.72, p=.000). Further testing is required with the control group, to compare with community resident elders in order to explore the effects on social skill of elderly.

During acute stages of hospitalized stroke patients, family caregivers face many challenges. They often experience emotional distress, social isolation, and financial constraints. However, the burden of caregiving of stroke patients in acute stages has never been studied properly. The purpose of this study was to investigate the factors related to the caregivers' burden with acute stroke. The subjects were 123 acute stroke patients and their caregivers who were admitted to neurology and neurosurgery units at Dan Kook University Hospital in Chung-Nam area. An interview was performed with the use of standardized questionnaire which included data pertaining to the patients/caregivers characteristics, caregiver burden (Modified Zarit's Burden Scale), and social support (Personal Resource Questionnaire). Our results showed that the mean burden score was 3.11, indicating high level of burden. Among the sub-domain scores, financial burden was the highest. In univariate analysis, the factors related to caregiver burdens were: inability to communicate between patients and caregiver(p<.001); low cognitive function of the patients(p<.001); low level of ADL(p<.001); the gender of caregiver(p<.001); the current employment status of caregivers(p<.01); the presence of social support for caregiver(p<.001); and the availability of alternative caregivers(p<.001). In multiple regression analysis, social support for family caregivers (87%), low level of patient's cognition (2%), availability of 2nd caregiver (1%), and gender of caregiver (female, 0.4%) were significant explanatory factors of overall burden. The caregivers' burden in acute stages during hospitalization following stroke was high. Recognition of high levels of caregivers' burden and those relating factors affecting caregiver burden may allow us to develop different nursing strategies to unload the level of burden for caregivers in acute stages of stroke.
