Artemisia princeps Pampanini is an herbal medicine widely used to immune function-related diseases, such as anti-oxidative, anti-inflammatory, and antibacterial agents. In this study, we investigated the anti-inflammatory effects of AP extract and underlying mechanisms were evaluated in RAW 264.7 cells. The effects of AP extract were also studied in a complete Freund's adjuvant (CFA)-induced arthritis and lipopolysaccharide (LPS)-induced inflammation mouse model. In RAW 264.7 cells, AP extracts significantly inhibited the LPS-induced nitric oxide (NO) production and inducible NO synthase and cyclooxygenase-2 protein expression. The LPS-induced phosphorylation of mitogen-activated protein kinases and nuclear factor-κB was also significantly blocked by AP extract in RAW 264.7 cells. Oral administration of AP extract suppressed the increase in mouse paw edema and spleen index compared to CFA-treated mice group. Histologically, the infiltration of inflammatory cells was increased in cartilage and synovium in the CFA-treated mouse group, whereas it was suppressed in the AP extract-administered group. Furthermore, AP extract treatment significantly reduced the inflammatory cytokine, tumor necrosis factor-α, levels in CFA and LPS-treated mouse. In conclusion, the anti-inflammatory and anti-arthritis effect of AP extract was confirmed in both in vitro and in vivo models, suggesting that Artemisia princeps Pampanini may be a candidate material for arthritis treatment.

The critical low temperature and response of the behavioral tolerance of red sea bream Pagrus major fingerlings were determined using the continuous behavior monitoring system (CBMS). The behavior of the experimental organisms was observed by decreasing the water temperature by 2.0℃ and 4.0℃ every 12 hours and 24 hours in the range of 8.0-20.0℃. An unstable behavior pattern was observed in red seabream fingerlings exposed to water temperatures below 12.0℃, in which the swimming activity decreased and repeatedly stopped, regardless of the exposure time and water temperature fluctuation. The swimming ability of the organisms exposed to 8.0-10.0℃ decreased sharply, and the behavior of staying at the bottom of the test tank was observed. Only 50 % of the organisms survived due to the low-temperature stress, and all individuals died within six hours after the cold shock. In addition, the behavior index (BI) decreased rapidly, and the amplitude change of the coefficient of variation (CV) was found to have a greater variation than the other water temperatures (p<0.05). Low-temperature stress of red sea bream is promoted at 12.0℃, and it is interpreted as the tolerance limit, which can induce a sublethal response of the organisms exposed to cold shock of 8.0-10.0℃.

This study investigated the effects of education for the elderly on their psychological well-being. Loneliness(negative state of emotion) and life satisfaction(positive state of emotion) were compared between participants and non-participants of educational programs for the elderly in order to learn whether participating educational programs influences their psychological well-being. The subjects of this research were 288(146 participants and 142 non participants) elderly who are 60 years and older, living in Seoul City and Gyeong Gi Do. They were selected by the judgmental sampling method and surveyed using structured questionnaire. Research instruments were consisted of the UCLA Loneliness Scale, Life Satisfaction Index-Z Scale(LSIZ) and several background questions. The result showed that the participants of the educational programs had a lower level of loneliness and a higher level of life satisfaction. The educational program for the elderly was effective for the psychological well-being of the aged. Multiple regression results showed that subjective health played the most important role in explaining the loneliness, followed by education level, elderly education participation, financial states. The results also showed that subjective health played the most important role in explaining the life satisfaction, followed by elderly education participation, religious activity participation, financial status. Implications for policy, practice, and further research were discussed.

Relationship between bone mineral density (BMD) and type 2 diabetes is still inconsistent. Recently, many epidemiologic data show that fracture risk is increased in type 2 diabetic patients regardless of BMD status. In this study, we used nation-wide data from 2008 to 2011 Korea National Health and Nutrition Examination Survey (KNHANES) to analyze the BMD status in patients with type 2 diabetes compared to non-diabetics. We included subjects aged 50 years or older in men (N=2,959, 2,430 without diabetes, 529 with type 2 diabetes) and postmenopausal women (N=2,902, 2,479 without diabetes, 423 with type 2 diabetes). Subjects with history of medication for osteoporosis or with illness or malignancy affecting bone metabolism were excluded. Data of anthropometric measurements and demographic characteristics were collected by trained examiner. Serum was separated from peripheral venous blood samples obtained after 8 hours of fasting. BMD was measured at lumbar spine and femur using dual-energy X-ray absorptiometry (DXA). There was a significant positive association between lumbar spine BMD and type 2 diabetes after adjusting age, gender, body mass index, monthly house income, education level, physical activity, daily calcium intake and vitamin D concentration by multiple regression analysis in all subjects. In the subgroup analysis by gender, this association was maintained both in male and female after adjusting those confounding factors. However, femur BMD was not different between type 2 diabetic and non-diabetic subjects. In conclusion, lumbar spine BMD was significantly higher in type 2 diabetic patients aged 50 years or more in men and postmenopausal women compared to non-diabetic subjects.

The effect of body composition such as lean mass and fat mass on bone mineral density (BMD) is complex and still controversial. In this study, we investigated the relationship between body composition and bone mineral density using nation-wide data from 2008 to 2011 Korea National Health and Nutrition Examination Survey (KNHANES) in 2,139 men and 2,193 postmenopausal women aged 50 years or older. Subjects with history of medication for osteoporosis or with diseases or malignancy affecting bone metabolism were excluded. Data of anthropometric measurements and demographic characteristics were collected by trained examiner. Fasting blood sample was obtained for blood chemistry analysis. BMD of the lumbar spine, total femur, and femoral neck, and body composition such as total lean mass (TLM), total fat mass (TFM), truncal fat mass (TrFM) were measured using dual-energy X-ray absorptiometry (DXA). There were significant positive correlations between body composition indices such as lean mass and fat mass with BMD. In multiple regression analysis, TLM was positively associated with BMD after adjusting age, body mass index, monthly house income, education level, physical activity, daily calcium intake and vitamin D concentration in both men and postmenopausal women. BMD at lumbar spine and femur in lowest quartile of TLM was significantly lower than other quartiles after adjusting those confounding factors in both gender. TrFM was negatively associated with total femur BMD in male and femur neck BMD in postmenopausal women after adjusting confounding factors. In conclusion, TLM is very important factor in maintaining BMD in subjects aged 50 years or older in men and postmenopausal women.

Ulcerative colitis is a disease that causes inflammation in the mucosal or submucosal layer of the colon. Previous studies have reported that obesity increases the prevalence of ulcerative colitis and aggravates the progression. This study was therefore undertaken to investigate whether curcumin inhibits the progression of ulcerative colitis caused by obesity. Mice were bred on a high-fat diet to induce obesity, and curcumin was administered with the high-fat diet to confirm the anti-inflammatory effect. To induce ulcerative colitis, dextran sulfate sodium (DSS) was administered orally, and clinical symptoms of colitis were subsequently observed. For histological evaluation of curcumin, the colon, liver and abdominal fat tissue samples were prepared and analyzed by hematoxylin and eosin (H&E) and Alcian blue-periodic acid-Schiff (PAS) staining. Our results confirm that consumption of curcumin resulted in decreasing the score of the disease activity index, and inhibited shortening of the colon length. In addition, inflammatory cell infiltration and mucosal damage were inhibited in the colon tissue of ulcerative colitis exacerbated by obesity. We further confirmed that exposure to curcumin significantly reduced the steatosis area of the liver and adipocytes of abdominal fat. In conclusion, we believe that curcumin can be applied as a therapeutic agent to treat ulcerative colitis, by inhibiting the progression of colitis caused by obesity.

The purpose of this study is to analyze regional variation factors of hypertension treatment rate in COVID-19 based on the analysis results based on ecological methodology. To this end, data suitable for ecological analysis were collected from the Korea Centers for Disease Control and Prevention's regional health statistics, local government COVID-19 confirmed cases, National Health Insurance Corporation, Health Insurance Review and Assessment Service's welfare statistics, and Korea Transport Institute's traffic access index. Descriptive statistics and correlation analysis were conducted using SPSS Statistics 23 for regional variation and related factors in hypertension treatment rate, and geographical weighted regression analysis was conducted using Arc GIS for regional variation factors. As a result of the study, the overall explanatory power of the calculated geo-weighted regression model was 27.6%, distributed from 23.1% to 33.4% by region. As factors affecting the treatment rate of hypertension, the higher the rate of basic living security medical benefits, diabetes treatment rate, and health institutions per 100,000 population, the higher the rate of hypertension treatment, the lower the number of COVID-19 confirmed patients, the lower the rate of physical activity, and the alcohol consumption. Percentage of alcohol consumption decreased due to COVID-19 pandemic. It was analyzed that the lower the ratio, the higher the treatment rate for hypertension. Based on these results, the analysis of regional variables in the treatment rate of hypertension in COVID-19 can be expected to be effective in managing the treatment rate of hypertension, and furthermore, it is expected to be used to establish community-centered health promotion policies.

This study developed an MEA program to which the invention technique was applied and analyzed the conceptual change of students. The MEA activity applying the invention technique (TRIZ) was composed of the topic of making a paper electric circuit in the section 'Using electricity' presented in the 6th grade textbook. As a way to materialize ideas for problem solving, among the TRIZ techniques, division, integration, multi-purpose, overlapping, subtraction, and converse techniques were extracted and applied. The devised program consists of examining invention techniques (1st session), problem-solving (2nd and 3rd sessions), and expressing the problem-solving process (4th session). As a result of applying to 6th grade elementary school students, it was confirmed that the scientific concept of the experimental group participating in the MEA class to which the invention technique was applied was improved compared to the control group participating in the general class. As a result of calculating the scientific concept improvement index, the control group showed a low educational effect of 0.15, and the experimental group showed an intermediate educational effect of 0.69. This study is meaningful in that it suggests a specific way to graft invention education into science subjects.
