Purpose: The aim of this study was to investigate the anti-osteoarthritic effect of the ethanol extract of Boswellia serrata gum resin (FJH-UBS) enriched with keto-β-boswellic acid and 3-O-acetyl-11-keto-β-boswellic acid compared to the conventional Boswellia serrata extract by adding the process of removing oil with hexane, in the monosodium iodoacetate (MIA)-induced osteoarthritis rat model. Methods: Sprague-Dawley (SD) rats were orally administered 0, 40, or 80 mg of FJH-UBS/kg body weight (BW)/day for 5 weeks and injected with MIA intra-articularly into right knee joints on day 15 to induce osteoarthritis. Changes in the knee joint microarchitecture, cartilage degradation, the expression of inflammatory mediators, cytokines, and matrix metalloproteinases (MMPs) in serum and synovia were observed. Results: Oral administration of FJH-UBS (80 mg/kg BW/day) reduced MIA-induced knee swelling and cartilage degradation and increased the expression of type II collagen and aggrecan in articular cartilage. Furthermore, FJH-UBS administration reduced MIA-induced increases in the serum levels of prostaglandin E2, leukotriene B4, interleukin (IL)-1β, IL-6, and MMP-13, and MIA-induced increases in the mRNA expressions of inducible nitric oxide synthase, cyclooxygenase-2, 5-lipoxygenase, IL-1β, IL-6, TNF-α, MMP-2, MMP-9, and MMP-13 in the synovia of knee joints. Conclusion: These results indicate that FJH-UBS exerts its anti-osteoarthritic effects by suppressing the expressions of inflammatory cytokines and MMPs and, thus, cartilage degradation. Furthermore, they suggest that FJH-UBS has potential use as a functional food that improves joint and cartilage health.

The purpose of this study was to investigate the ability of visual-motor integration (VMI) in elderly patient with diabetes mellitus(DM). Male elderly (from 65 to 70 years old) with DM and non-DM disease were participated in this study. Participants were divided into three group (n=30 in each group): the control group, non-DM group, and DM group. Data were collected through VMI-3R questionnaires and interviews. Statistical differences among groups were determined by one-way ANOVA followed by Duncan Post-hoc test and results were expressed the mean ± S.D. or percentage (%). The present results showed that the score of both VMI 24 and VMI 50 in DM group were statistically lower than both the control and Non-DM groups. Also, the lower rate of correct and higher rate of error in VMI-3R was observed in DM group compared to both the control and Non-DM groups. The item analysis of VMI-3R revealed that the most higher rate of error was observed in item 24 in all groups. Based on these results, this study suggests that DM might aggravate the function of visual-motor integration in male elderly.

We investigated the influences of positive thought about social capital on social participation of the elderly Koreans. The study design was cross-sectional analysis of the National Statistic Office Study of Korean Society Statistics Survey 2003. Participants were total of 8,586 representative samples. Two types of social participation were investigated: meeting attendance and volunteer obligations. The base model included five thoughts about social capital that must be settled as a priority in Korea, i.e., reducing the differences between the rich and the poor, reducing the crime rate, reducing regulations and corruption, improving the moral level, eliminating environmental pollution. Social participation was influenced by positive thoughts about social capital, and different kinds of thoughts had different influences on different types of social participation. The elderly who responded positively to 'reducing the differences between the rich and the poor' attended all two types of social participation more. Along with education and health status, positive thought about social capital is another important factor that influences increased social participation. It may also compensate for deteriorating health with increasing age by promoting social participation. Encouraging social participation is a good way to improve the health of the elderly, as are efforts to change thought about social capital positively.

What are the implications for us through the discussion on the effect of Germany's dual system of vocational education on the youth unemployment rate? You can find out what kind of evaluation Germany is receiving on the dual system vocational education system implemented based on the 'Vocational Education and Training Act' (Berufsbildungsgesetz), and the specific system establishment form for the industry-academic-government cooperation system. It was possible to present the crises and problems of these systems. Responsibility for the dual system of vocational education in Germany rests with the national and state ministries of education, and private enterprises and chambers of commerce are responsible for business practices. Practical work in a company is conducted through skill-oriented education, and in vocational schools, competency-oriented theoretical education is received. In addition, the necessity and demand for digital vocational and education training in accordance with German Idustrie 4.0 and higher vocational education degree acquisition through dual-degree courses were identified. It can be seen that the youth unemployment rate is the lowest in Europe due to the successful development and utilization of human resources to improve the competitiveness of companies, such as dual vocational education and training (VET) at all levels, higher vocational education at universities, and continuing vocational education programs. Vocational education in Korea will also be able to improve the unemployment rate by establishing a system that allows schools and businesses to conduct vocational education and training simultaneously. In particular, it was possible to judge the necessity of 'close consultation between labor, management, and government', which we consider the most important and should lead to in-depth discussion and cooperation for dual education between vocational schools and companies.

Since the introductionof modern therapies, more children with cancer have survived their illness. As a result, an interest in the degree of adjustment achieved by cancer survivors has increased. In this study, quality of life and behavior problemsof child and adolescent cancer survivors were compared with those of healthy controls. Also, the patternsof the discrepancy between parent-report and self-report were compared. Childhood cancer survivors aged 8-18 and their mothers were participated in the study. Parent and self report versions of PedQL were administered to assess the quality of life. K-CBCL and K-YSR were further completed to assess internalizing and externalizing behavior problem. Results suggested that cancer survivors generally showed lower quality of life in physical and social domains and more internalizing behavior problem than healthy control group. However, the results were affected by the domain, age group, and informant. The pattern of discrepancy between parent and self report was similar. All parents reported higher levelsof quality of life and lower levels of behavior problems compared to the self reports of their siblings. In assessing internalizing problem behaviors, cancer survivor group showed greater discrepancy than the healthy control group.The implications, limitations, and directions for future research were also discussed.
