Profit-keeping behaviors naturally occur in the market to satisfy consumers, and the logic behind it lies in the economies of scale. On the flip side, some commodities transacted in the market are not available or can not be easily acquired unless the demand is high enough. Under this proposition, some consumers rise and find their own solution to meet the services at a reasonable cost or at an adequate level. The commonly adopted way is to establish a cooperative, and it stirs purchasing power by pooling resources and further bargains price and service quality. As a consumer cooperative, housing cooperatives notably found in rural towns enable the elderly to continue independent living. This study is to take a closer look at residential life of the rural elderly in housing cooperatives. Utilizing in-depth focus group interviews with 40 residents in four housing cooperatives, this qualitative research draws main factors affecting the decision to move in, residential assessment, and strengths and weakness of living in a housing cooperative. The primary factor influencing the moving decision is to continue to independent living in a familiar community, and the bottom line is planning ahead. Frailty and bereavement are found to be the leading occasions for them to move. The participants are satisfied with the independent living arrangement, and particularly, cited such features as safety and security, elderly-friendly design, common spaces, freedom, social activities and efficient living. Also, it is stated that some cooperative natures such as control over the property and giving a voice on management render positive impacts on the satisfaction with communal living. In spite of all the benefits and strengths, participants face with a public notion that an independent living arrangement like a housing cooperative has never done before in rural towns, so that most people recognize it as part of dependent living arrangements like nursing home.

The purpose of this study was to develop a cognitive rehabilitation program based on the cognitive activities of the elderly with mild dementia using the weekly care facilities in Daegu city memory and to provide useful welfare services for the elderly with mild dementia. In Korea, there is not much development of community-based integrated intervention program for demented patients who are still in the present situation. The results of this study suggest that the cognitive rehabilitation program for the elderly with mild dementia is suitable to be applied as a group in the case of community based protective editorials and may be a basis for management of mild dementia patients. It seems that there may be differences in the appropriate intervention methods and effects. Therefore, it is expected that the individualized customized strategy will maximize the effect. Therefore, more specific and individualized nursing intervention program should be concurrently developed.

The tools that classify the severity of patients based on the prediction of mortality include APACHE, SAPS, and MPM. Theses tools rely crucially on the evaluation of patients' general clinical status on the first date of their admission to ICU. Nursing activities are one of the most crucial factors influencing on the quality of treatment that patients receive and one of the contributing factors for their prognosis and safety. The purpose of this study was to identify the goodness-of-fit of CPSCS of critical patient severity classification system(CPSCS) and Glasgow coma scale(GCS) and the clinical usefulness of its death rate prediction. Data were collected from the medical records of 187 neurological patients who were admitted to the ICU of C University Hospital. The data were analyzed through $x^2$ test, t-test, Mann-Whitney, Kruskal-Wallis, goodness-of-fit test, and ROC curve. In accordance with patients' general and clinical characteristics, patient mortality turned out to be statistically different depending on ICU stay, endotracheal intubation, central venous catheter, and severity by CPSCS. Homer-Lemeshow goodness-of-fit tests were CPSCS and GCS and the results of the discrimination test using the ROC curve were $CPSCS_0$,.734, $GCS_0$,.583, $CPSCS_{24}$,.734, $GCS_{24}$,.612, $CPSCS_{48}$,.591, $GCS_{48}$,.646, $CPSCS_{72}$,.622, and $GCS_{72}$,.623. Logistic regression analysis showed that each point on the CPSCS score signifies1.034 higher likelihood of dying. Applied to neurologically ill patients, early CPSCS scores can be regarded as a useful tool.

Purpose: This study is intended to analyze factors of metabolic syndrome and vitamin D deficiency with resources obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) V conducted in 2010. Methods: The subjects were 870 adolescents aged from 10 to 18 who participated in the first KNHANES V. Secondary data analysis was done by Chi-square, ANOVA, correlation analysis and simple linear regression. Results: The influencing factors of metabolic syndrome were vitamin D, systolic blood pressure and diastolic blood pressure, which were statistically significant. Simple linear regression was conducted to identify the influence of vitamin D on the factors related to metabolic syndrome, which showed that waist size (t=-1.97, p<.05), systolic blood pressure (t=-2.88, p<.01), and diastolic blood pressure (t=-5.72, p<.001) were influenced by vitamin D. In addition, each factor decreased by .131, .209, and .355, respectively, when vitamin D increased by one unit. Conclusion: Metabolic syndrome is a factor to be considered in order to improve adolescent health and form adolescent health behaviors. Schools, families, and local communities should cooperate with each other on the foundation of a regular health screening process and systematic health education programs. In addition, it is expected enhanced physical activities and sports club participation can prevent metabolic syndrome and increase vitamin D among adolescent.

Anthocyanidins, the aglycones of anthocyanins, are natural colorants belonging to the flavonoid family. Cyanidin is one of the anthocyanidins, used for their antioxidant properties. Furthermore, previous studies have shown anthocyanidin-rich material extracts or aglycone form inhibit growth and induce apoptosis of cancer cells. But, Tumor metastasis is the most important cause of cancer death, and various treatment strategies have targeted on preventing the occurrence of metastasis. This study investigated the effects of cyanidin on metastasis processes, including motility, invasion and activity of MMP-2 and MMP-9 in MDA-MB-231 human breast cancer cell lines. We cultured MDA-MB-231 cells in presence of various concentrations 0, 5, 10 and 20 ${\mu}M$ of cyanidin. The cell motility was significantly decreased dosedependently in cells treated with cyanidin (p < 0.05) and cyanidin treatment caused the significant suppression of the invasion (p < 0.05). MMP-2 and MMP-9 activities, and MMP-9 mRNA express were not affected by anthocyanin treatment. In conclusion, cyanidin inhibits cell motility, invasion in MDA-MB-231 human breast cancer cell lines.

Plumbagin, a hydroxy 1,4-naphthoquinone compound from plant metabolites, exhibits anticancer, antibacterial, and antifungal activities via modulating various signaling molecules. However, its effects on vascular functions are rarely studied except in pulmonary and coronary arteries where NADPH oxidase (NOX) inhibition was suggested as a mechanism. Here we investigate the effects of plumbagin on the contractility of skeletal artery (deep femoral artery, DFA), mesenteric artery (MA) and renal artery (RA) in rats. Although plumbagin alone had no effect on the isometric tone of DFA, $1{\mu}M$ phenylephrine (PhE)-induced partial contraction was largely augmented by plumbagin (${\Delta}T_{Plum}$, 125% of 80 mM KCl-induced contraction at $1{\mu}M$). With relatively higher concentrations (>$5{\mu}M$), plumbagin induced a transient contraction followed by tonic relaxation of DFA. Similar biphasic augmentation of the PhE-induced contraction was observed in MA and RA. VAS2870 and GKT137831, specific NOX4 inhibitors, neither mimicked nor inhibited ${\Delta}T_{Plum}$ in DFA. Also, pretreatment with tiron or catalase did not affect ${\Delta}T_{Plum}$ of DFA. Under the inhibition of PhE-contraction with L-type $Ca^{2+}$ channel blocker (nifedipine, $1{\mu}M$), plumbagin still induced tonic contraction, suggesting $Ca^{2+}$-sensitization mechanism of smooth muscle. Although ${\Delta}T_{Plum}$ was consistently observed under pretreatment with Rho A-kinase inhibitor (Y27632, $1{\mu}M$), a PKC inhibitor (GF 109203X, $10{\mu}M$) largely suppressed ${\Delta}T_{Plum}$. Taken together, it is suggested that plumbagin facilitates the PKC activation in the presence of vasoactive agonists in skeletal arteries. The biphasic contractile effects on the systemic arteries should be considered in the pharmacological studies of plumbagin and 1,4-naphthoquinones.

The purpose of this study was to investigate the effects of early cognitive training and tailored telephone coaching program for ischemic stroke. Among 28 participants, assigned into the experimental(n=15) and control group(n=13). Only the experimental group was received a 4-week cognitive training and 11 session of tailored telephone coaching. The effect ot the program was evaluated four times(baseline, 4weeks, 8weeks, 12months) using the tool on Depression, Mini Mental State Examination(MMSE), Neuropsychological battery, Activities of Daily Living(ADL). The repeated measures ANOVA showed that the experimental group showed improvement in MMSE, verbal memory and executive function compared to the control group. Especially, the improvement of executive function which is related to ADL was a remarkable result. This suggests that early intervention is very important for recovery cognitive function and independent daliy life after stroke, and periodic telephone coaching should be done together for mid-to long term effects.
