Purpose: This study was performed to investigate the effects of Tai Chi exercise on physical fitness and quality of life (QOL) in elderly women. Methods: This study was designed as a quasi-experimental, nonequivalent control group pre-post test design. The subjects were elderly women over 60 years old who enrolled senior citizen centers and elderly welfare center. Thirty-three people were conveniently assigned to an experimental group (n=15) or a control group (n=18). The data were collected from September 2009 to May 2010. The experimental group was trained Tai Chi exercise for 8 weeks (one hour Tai Chi classes twice a week and once a week by themselves at home). Data were analyzed by Fisher's exact test, ${\chi}^2$-test and independent t-test. Results: The experimental group experienced significant improvements in flexibility. The experimental group experienced significant improvements in physical component summary (p=.017) and mental component summary (p=.027) of QOL. Conclusion: Tai Chi exercise can be used as a nursing intervention for improvement of physical fitness and QOL in elderly women.

The present study investigated how one's cognitive resources are related to speech perception by examining Korean speakers' executive function (EF) capacity and its association with voice onset time (VOT) and f0 sensitivity in identifying Korean stop laryngeal categories (/t'/ vs. /t/ vs. /t^h/). Previously, Kong et al. (under revision) reported that Korean listeners (N = 154) in Seoul and Changwon (Gyeongsang) showed differential group patterns in dialect-specific cue weightings across educational institutions (college, high school, and elementary school). We follow up this study by further relating their EF control (working memory, mental flexibility, and inhibition) to their speech perception patterns to examine whether better cognitive ability would control attention to multiple acoustic dimensions. Partial correlation analyses revealed that better EFs in Korean listeners were associated with greater sensitivity to available acoustic details and with greater suppression of irrelevant acoustic information across subgroups, although only a small set of EF components turned out to be relevant. Unlike Seoul participants, Gyeongsang listeners' f0 use was not correlated with any EF task scores, reflecting dialect-specific cue primacy using f0 as a secondary cue. The findings confirm the link between speech perception and general cognitive ability, providing experimental evidence from Korean listeners.

Some patients with type 1 and type 2 diabetes mellitus (DM) present with cognitive dysfunctions. The pathophysiology underlying this complication is not well understood. Type 1 DM has been associated with a decrease in the speed of information processing, psychomotor efficiency, attention, mental flexibility, and visual perception. Longitudinal epidemiological studies of type 1 DM have indicated that chronic hyperglycemia and microvascular disease, rather than repeated severe hypoglycemia, are associated with the pathogenesis of DM-related cognitive dysfunction. However, severe hypoglycemic episodes may contribute to cognitive dysfunction in high-risk patients with DM. Type 2 DM has been associated with memory deficits, decreased psychomotor speed, and reduced frontal lobe/executive function. In type 2 DM, chronic hyperglycemia, long duration of DM, presence of vascular risk factors (e.g., hypertension and obesity), and microvascular and macrovascular complications are associated with the increased risk of developing cognitive dysfunction. The pathophysiology of cognitive dysfunction in individuals with DM include the following: (1) role of hyperglycemia, (2) role of vascular disease, (3) role of hypoglycemia, and (4) role of insulin resistance and amyloid. Recently, some investigators have proposed that type 3 DM is correlated to sporadic Alzheimer's disease. The molecular and biochemical consequences of insulin and insulin-like growth factor resistance in the brain compromise neuronal survival, energy production, gene expression, plasticity, and white matter integrity. If patients claim that their performance is worsening or if they ask about the effects of DM on functioning, screening and assessment are recommended.

Purpose: In this study a pilates exercise program using self-efficacy sources was provided for women 65 years of age or older and the effects on physical fitness, body composition, depression, self-efficacy, and health-related quality of life were tested. Methods: A quasi-experimental study employing a nonequivalent control group, pre-post design was conducted. The subjects consisted of 30 older women in the experiment group and 30 in the comparison group. The intervention was conducted twice a week for a period of 12 weeks. During this period, the pilates exercise program using self-efficacy sources (health education, phone coaching, mentoring, checking homework, recreation) were provided in the experiment group and pilates exercise program were offered in the comparison group. Chi-square test, independent t-test, ANCOVA were used for data analysis. Results: Following completion of the program, upper muscle strength (F=4.131, p=.047), low muscle strength (F=5.558, p=.022), upper flexibility (F=5.252, p=.026), static balance (F=5.957, p=.018), dynamic body balance & agility(F=18.971, p<.001), endurance(F=10.058, p=.002), muscle mass (F=5.748, p=.020), depression (F=4.493, p=.038), Self-efficacy (F=33.853, p<.001), and Health-related quality of life(F=5.586, p=.022) were significantly better in the experimental group. Conclusion: Findings from this study indicate that the pilates exercise program using self-efficacy sources are effective in enhancing physical fitness, body composition, self-efficacy and health-related quality of life and in decreasing depression for female elders and could therefore be regarded as positive program for promotion of physical and mental health for older women.

The lastest art is being characterised by an ever active exchange between different genre. This is a study on the installation aspect in deconstruction architectured and interior design. The progressive and aggressive nature of installatation art embodies uncatagorized genre, the freedom of material application, introduction of the notion of time in space, the reversion of subject and object, the union of art and every experience, understanding of object through deconstruction, enlargement of concept of space, collage-style composition and layer technique. I can conclude that the installation aspect in Tshumi's Parc de la Villette is its call upon the audience to actively participate, the introduction of a coincidental conjunction, its challenge on the conventional idea of park and its flexibility caused by human activity and time. In Hadid's Hong Kong Peak Club the installation aspect is the application of layer technique using four enormous beams horizontally laid out on a man-made moutain. Furthermore, Libeskind's pursuit of the mental in Berlin Museum Extension through the penetration of an invisible line into a void creates a new interpretation of the role of a museum and thus relates itself to installation art. The installation aspect in Himmelblau's Vienna Roof Renovation is the literal deconstruction of the roof of an old building in the old section of Wien and the expression of time and space through the interrelationship between interior and exterior environment by the use of juxtaposition technique. Finally, I note that the installation aspect in Gehry's Santa Monica Residence is the reorganization of cheap material as a form of 'object', that creates spon-taneity, movement as well as flow of time in space and ex-hibit the double-sidedness of the visible world.

Recently (2010), South Korea's aging rate is 11%. and expected to be 32.3% in 2040, and Japan's aging rate in 2010 is 23%, and in 2040 is expected to be 34.5%. As aging progresses, it is increasing with the elderly person with dementia. However, elderly welfare facilities are insufficient. To take care stability of elderly people with mental and physical disabilities, we need to prepare a lot of welfare facilities for the elderly. Whenever physical conditions and service needs change of the disability elderly, Elderly are forced to move to the other facility. They move from familiar places, beloved local base to unfamiliar places. They are under a lot of stress in order to adapt to new environment. This research is to check out the possibility of the systems and the effectiveness of various services and the flexibility of management in Japan. Takurosyo is responsible for a variety function of elderly medical welfare facilities. Within a short time, our country, has entered into a super-aged society, elderly health and welfare facilities are needed. However, because it requires enormous financial, it is difficult to build a new building in reality, However, if remodeling existing buildings, We can build many low-cost small-scale multi-functional welfare facilities such as the takurosyo. Such that facility would be available to us.

This study was designed to investigate the effect of a combined stimulus which was composed of chiropractic massage and thermotherapy on the relief of mental and physical stress. Fifteen healthy male subjects were treated with three type of stimuli; control (without any stimulus), a single stimulus (only chiropractic) and a combined stimulus. To evaluate the effects of stimuli, visual analogue scale (VAS), trunk extension, electromyogram (EMG) on erector spinae muscle and electrocardiogram (ECG) were measured and analyzed before and after stimuli. In the control group, there were no significant changes in EMG root mean square (RMS) value and low Frequency/high Frequency (LF/HF) ratio (p > 0.05, p > 0.05). However, both stimulus groups showed significant increases in trunk extension and EMG RMS values (p < 0.05, p < 0.05), but significant decreases in LF/HF ratios (p < 0.05). Particularly the decrement rate in LF/HF ratio was significantly higher in the combined stimulus group than that in the single stimulus group (p < 0.05). Also, a significantly lower VAS was recorded after combined stimulus. Our findings indicate that the combined stimulus might not only improve flexibility and strength of muscle, but also active parasympathetic nerve activity. The combined stimulus may thus contribute to relieve the stress and to enhance the muscle function.
