A Study on the Influence on Mental Health of Participants of the Job Creation Project for the Japanese Elderly

This research aims to analyze the effects on the Subject’s mental health of the Job Creation Project for the elderly in Japan. The subjects of this survey in 2007 were about 1500 participants in the Job Creation Project of Silver Manpower Center in Japan, 970 cases of whom were dataanalyzed.The results of this research are as follows:First, as a result of descriptive statistics of mental health, it was unders food that the average of total mental health is 2.91. As a result of verification of mental health difference, the score of mental health showed significant difference statistically according to job type or motivation of participation, and no significant difference statistically according to satisfaction with job project or duration of participation. With respect to job types, mental health is higher in desk job ormanagement/inspection or technical work than in simple work. Also among the motivations of participation mental health is highest for participation in society than for income.Second, a hierarchical multiple regression analysis was performed by including populationsociological properties variables and four subordinate variables of actual conditions of participation in the Job Creation Project for the Elderly in order to analyze the variables which influence the participant mental health. According to the result of analyzing the effects on total mental health, male gender and better physical health condition were seen to have positive effects on total mental health.It is noted that among the motivations of participation, participation in society, and satisfaction with the Job Project, had positive influence

A Study on the Korean Senior Employment Promotion Project that Influence on the Quality of Participants --Focused on gender difference--

This study analyzes the Korean senior employment promotion projects influence on the quality of elderly peoples lives. This study is focused on the gender differences, and based on their identification it provides policy implications to use for senior job creation initiatives as a way to promote improved quality of their lives.For this study, university students who were trained about interview techniques from October, 2007 to January, 2008 visited 33 organizations in each of Seoul’s administrative districts including social welfare centers, senior centers, senior employment support centers and community senior clubs. Ten to thirty older people of each organization had face-to-face interviews with the interviewers, resulting in 595 questionnaires collected. After data cleaning, a total of 574 questionnaires were used for this study.SPSS 14.0 was used to conduct data analysis, and many analysis techniques were employed for the analysis: frequency analysis, independent samples t-test, one-way ANOVA, correlation analysis, hierarchical multiple regression analysis.The study uses regression analysis to find out the influence of variables on quality of life, and found that older men felt happier when they were early on in their retirement years, healthier and they participated in the project for an extended time. On the other hand, older women said they were happier when they were healthier and their job gave them more satisfaction when their job was not for public service or human resource dispatch

A Synergistic Anti-Diabetic Effect by Ginsenosides Rb1 and Rg3 through Adipogenic and Insulin Signaling Pathways in 3T3-L1 Cells

Although ginsenosides Rb1 and Rg3 have been identified as the significant ginsenosides found in red ginseng that confer anti-diabetic actions, it is unclear whether insulin-sensitizing effects are mediated by the individual compounds or by their combination. To determine the effect of ginsenosides Rb1 and Rg3 on adipocyte differentiation, 3T3-L1 preadipocytes were induced to differentiate the standard hormonal inducers in the absence or presence of ginsenosides Rb1 or Rg3. Additionally, we determined the effects of Rb1, Rg3, or their combination on the expression of genes related to adipocyte differentiation, adipogenic transcription factors, and the insulin signaling pathway in 3T3-L1 cells using semi-quantitative RT-PCR. Rb1 significantly increased the expression of CEBP alpha, PPAR gamma, and aP2 mRNAs. However, Rg3 exerted its maximal stimulatory effect on these genes at 1 mu M concentration, while a high concentration (50 mu M) showed inhibitory effects. Similarly, treatment with Rb1 and Rg3 (1 mu M) increased the expression of IRS-1, Akt, PI3K, GLUT4, and adiponectin. Importantly, co-treatment of Rb1 and Rg3 (9:1) induced the maximal expression levels of these mRNAs. Our data indicate that the anti-diabetic activity of red ginseng is, in part, mediated by synergistic actions of Rb1 and Rg3, further supporting the significance of minor Rg3

Ameliorating effects of Mango (Mangifera indica L.) fruit on plasma ethanol level in a mouse model assessed with 1H-NMR based metabolic profiling

The ameliorating effects of Mango (Mangifera indica L.) flesh and peel samples on plasma ethanol level were investigated using a mouse model. Mango fruit samples remarkably decreased mouse plasma ethanol levels and increased the activities of alcohol dehydrogenase and acetaldehyde dehydrogenase. The 1H-NMR-based metabolomic technique was employed to investigate the differences in metabolic profiles of mango fruits, and mouse plasma samples fed with mango fruit samples. The partial least squares-discriminate analysis of 1H-NMR spectral data of mouse plasma demonstrated that there were clear separations among plasma samples from mice fed with buffer, mango flesh and peel. A loading plot demonstrated that metabolites from mango fruit, such as fructose and aspartate, might stimulate alcohol degradation enzymes. This study suggests that mango flesh and peel could be used as resources for functional foods intended to decrease plasma ethanol level after ethanol uptake

Under-reporting of Energy Intake from 24-hour Dietary Recalls in the Korean National Health and Nutrition Examination Survey

AbstractObjectivesChronic degenerative diseases are closely related to daily eating habits, nutritional status, and, in particular, energy intake. In clarifying these relationships it is very important for dietary surveys to report accurate information about energy intake. This study attempted to identify the prevalence of the under-reporting of energy intake and its related characteristics based on the Korean National Health and Nutrition Examination Survey conducted in the years 2007–2009.MethodsThe present study analyzed dietary intake data from 15,133 adults aged ≥19 years using 24-hour dietary recalls. Basal metabolic rates were calculated from the age- and gender-specific equations of Schofield and under-reporting was defined as an energy intake <0.9, represented by the ratio of energy intake to estimated basal metabolic rate.ResultsUnder-reporters (URs) accounted for 14.4% of men and 23.0% of women and the under-reporting rate was higher in the age group 30–49 years for both men and women. The results from an analysis of the age-specific socioeconomic characteristics of participants classified as URs showed that under-reporting was high in women living alone and in women with only elementary school education or no education. The results from an analysis of the health-specific characteristics of URs showed that a large proportion of URs had poor self-rated health or were obese, or both, compared with non-URs. The proportion of participants who consumed less than the estimated average requirements for nutrients was significantly higher in URs compared with non-URs.ConclusionThe under-reporting of energy intake was associated with age, gender, education level, income level, household status (single-person or multi-person), self-rated health, physical activity, and obesity

The Acute and Chronic Effect of Korea Ginseng Supplement on Exercise Performance, Cognitive Function, and Fatigue Recovery

The purpose of this study was to determine the acute and chronic effects of Korean ginseng supplements on exercise performance, cognitive function, and fatigue recovery. The study used double-blind, placebo-controlled, crossover design. Twelve healthy adult males (age = 31 ± 6.86 yrs) were randomly assigned to either KGD or placebo trials. All subjects conducted the exercise consisted with 30 minutes cycling at 70-75% of VO2 max followed by 16 km time trial with 30 minutes resting periods. All subjects were tested for muscular power, strength, endurance, cognitive function, and fatigue. The subjects took KGD (280 ml containing 5.88 mg of ginsenosides) or placebo 90 mins before exercise trials and following 7 days. The blood sample was drawn for IL-6, myoglobin, and total antioxidant capacity immediately after time trial, as well as 2, 24, 48, and 72 hours. After 2 weeks of wash-out period, the subjects were crossed over into the opposite trial and performed the same test. Repeated measures ANOVAs were used to examine the effect of acute and chronic intake of ginseng on exercise performance and blood variables. An alpha of .05 was used, and the Greenhouse-Geisser (G-G) adjusted F and degrees of freedom were reported. In a placebo trial, peak power and mean power levels were significantly decreased across time, F (1.47, 13.24) = 4.63, G-G p = .039, h2p = .340 and F (1.46, 13.13) = 5.31, G-G p = .028, h2p = .371 while no differences were found in a ginseng trial. In a placebo trial, average reaction time (ART) was significantly increased across time, F (1.29, 11.63) = 10.81, G-G p = .005, h2p = .546, but in a ginseng trial, no difference in ART was found across time, F (1.54, 13.86) = 4.02, G-G p = .051, h2p = .309. There was a significant increase in TAC across time in a ginseng trial, F (1.42, 11.37) = 5.07, G-G p = .035, h2p = .388 while no difference was found in a placebo trial. No significant differences were found in other variables from placebo and ginseng trails. The 7 days of KRG supplementation significantly reduced the serum myoglobin concentration across time in the KGD trial, F (1.88, 13.17) = 5.18, G-G p = .023, while no difference was found in the placebo trial, F (2.21, 17.66) = .88, G-G p = .443. No significant differences were observed in serum total antioxidant activity and IL-6 between KGD and placebo trials. The study shows that Korean ginseng supplement before stating the exercise improve anaerobic capacity, cognitive function in particular psychomotor vigilance task, and fatigue recovery during cycling exercise. And 7 days of Korean ginseng supplement reduces muscle damage and fatigue after cycling exercise
