Purpose: This study tries to comprehend older adults' perspectives of community supports and health services in a South Korean city and identify important sociodemographic and health characteristics that affect their perspectives. Methods: 166 older adults were involved in this cross-sectional study. Questions on background characteristics and community supports and health services criteria (categorized as service accessibility, offer of services, voluntary support, or emergency care planning) based upon the WHO's Age-Friendly Cities Guide were used. The data were analyzed using paired and independent t-tests, one-way ANOVA, and hierarchical multiple regression analyses. Results: emergency care planning was rated as the most important by the participants (mean age=76.24 years, 22.9% male), while its current level of performance was lowly appraised (p<.001). The rated importance for each category differed based on individual characteristics. Depression (p=.016), older age (p=.012), and restricted network type (p=.039) were significantly related to ascribing a higher degree of importance to community services. Conclusion: Community initiatives are warranted to optimize emergency care for older adults. This planning must be based on the unique characteristics of older adults in coordination with supportive resources. In addition, comprehensive assessments are warranted before implementing action plans to ensure that the multi-dimensional problems of older adults are incorporated.

Sep gene, which is one of the cell division genes coding for penicillin binding protein 3 was subcloned from ${\lambda}607sep^{+2}$ to plasmid pBR322. which has a strong promotor such as lac UV5(lacP). It was confirmed that the sep gene cloned to pLJ3 was in the proper orientation for expressionfrom lactose promotor. To analyze the expression efficiency of sep gene within the plasmids newly constructed, sep mRNA was assated by using ${\lambda$\mid$\;607sep^{+2}$ DNA as a probe. Sep mRNA level was increased 25 times in the cells carrying sep gene cloned to pBR322 compared to E. coli C600 which has wild type sep gene within the chromosome instead of plasmed. Furthermore, the cells carrying sep gene cloned to pLJ3 derected the synthesis of about 50 times as much sep mRNA as did cells carrying sep gene cloned to pBR 322, representing that the sep gene was successfully cloned to pLJ3.

This study is a descriptive paper addressing the relationship between test anxiety, self-esteem and the mental health levels of freshmen and third year students of Dental Hygienics. In late 2011, we received a total of 298 questionnaires from freshmen and third year Dental Hygienics students of three South Korean universities, located specifically in Seoul and Gyeonggi-do. The timing of this questionnaire was significant because it was one week prior to midterm examinations. The results were as follows:1. There was a statistically significant relationship between age (t=3.017, p<.001) and grade(t=2.665, p<0.05), subjective health status(t=27.513, p<.001). 2. The lower the participants' reported mental health in general, the higher their level of test anxiety (r=.565, p<.001), broken down into two subdivisions: cognitive text anxiety (r=526, p<.001) and emotional test anxiety (r=.534, p<.001). 3. When considering the factors that influence the general mental health of participants, there were age differences. For first year students, their subjeetive health status (${\ss}$=-.300, p<.001) and test anxiety (${\ss}$=.530, p<.001) were significant. For third year students, this was also true (subjective mental condition: ${\ss}$=-.242, p<.001 and test anxiety: ${\ss}$=.350, p<.001) but self-worth was also significant (${\ss}$=.377, p<.001). The results of this study suggest that the key factors that influence the mental health level of students Dental Hygienics are test anxiety, subjective appraisal of health level, and general self-worth. A systematic approach is therefore needed to improve students' mental health and reduce test anxiety. Health management programs which address and test students' physical health will also be important in improving student performance and welfare.

To study the working mechanisms for non-starch polysaccharidases to improve the growth performance of broiler chickens, a 21-day feeding trial was conducted. Two dietary treatments were included: 1) wheat diet (the control); 2) wheat+xylanase diet (xylanase, Allzyme PT, Alltech, Kentucky, USA). There were 8 replicates with 8 birds each for each treatment and the experimental diets were given to birds from hatch. Feed intake and body weight were measured on days 7 and 21. At the same ages, samples were taken for the determination of selected groups of luminal and mucosa-associated bacteria, mucosal morphology, brush-border membrane (BBM) bound enzyme activity and ileal nutrient digestibility. The xylanase supplement increased (p<0.05) body weight gain (BWG) and improved feed conversion ratio (FCR) at the end of the experiment but protein and starch digestibilities were not affected (p>0.05) by xylanase. Up to day 7, xylanase increased the counts of C. perfringens in the ileum and total anaerobic bacteria (TAB) in the caeca (p<0.05, p=0.07, respectively). By day 21, the counts of ileal lactobacilli (p<0.05) and TAB (p=0.07) were lower in birds given the xylanase-supplemented diet than in those on the control diet. No significant differences were observed in the counts of mucosa-associated lactobacilli and coliforms between xylanase treatment and the control at both ages. Villus height at the jejunum was not affected (p>0.05) by the supplement but crypt depth at the same site was reduced at day 7. Also, xylanase tended to increase the concentration of BBM protein (p = 0.09) and the specific activity of sucrase (p = 0.07) at day 21.

The purposes of this study were to classify university students by their lifestyle and to investigate the relationships between lifestyle and coffee satisfaction. The survey had been undertaken for 360 Korean and Chinese university students in Daejeon from November to December 2009. A total of 242 usable questionnaires were received with 67.2% response rate. The statistical analysis was performed by the SPSS 18.0 package program. Lifestyles of subjects, based on AIO (Activities, Interests, Opinions) method and factor analysis, were segmented into 2 groups of "outgoing activity" (n = 137) and "introverted devotion" (n = 105). "Outgoing activity" group exhibited highly health-oriented (p < 0.001) and convenience-oriented (p < 0.001) characteristics, but "introverted devotion" group showed highly goal-oriented (p < 0.01) and safety-oriented (p < 0.01) features. Comparing to "introverted devotion" group, "outgoing activity" group showed higher intake of coffee (p < 0.01) and more expense for beverage (p < 0.01). Three factors were extracted from 15 coffee quality attributes by factor analysis; "fundamentals", "supplement" and "inducement". These factors were positively correlated with coffee satisfaction according to lifestyle groups (p < 0.01). For "outgoing activity" group, 'fundamentals' was independent factor for satisfaction on coffee in coffee house (${\beta}$ = 0.268, p < 0.05) and canned or bottled coffee (${\beta}$ = 0.314, p < 0.01), and "supplement" was independent factor for satisfaction on coffee in vending machine (${\beta}$ = 0.235, p < 0.05). For "introverted devotion" group, "inducement" was independent factor for satisfaction on coffee in vending machine (${\beta}$ = 0.238, p < 0.001). These results provide an understanding for lifestyles of coffee consumers and give an insight into differentiated marketing plans for coffee industry.

This study was to investigate the anti-inflammatory effects of Prunellae Herba(PH). The generation of superoxide anion radical (․O₂-), nitric oxide (NO), peroxynitrite (ONOO-) and Prostaglandin E₂(PGE₂) were measured in the H₂O₂-Treated renal epithelial cells(LLC-PK1 cell) of mouse. And the effects of Prunellae Spica on the expression of NF-κB (p50, p65), IKK-α, phospho-IκB-α and inflammation-related proteins, COX-2, iNOS, IL-1β and VCAM-1, were examined by western blot. The fluorescent probes, 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) and dihyldrorhodamine 123 (DHR 123) were used to estimate the scavenging effect of Prunellae Spica on ․O₂-, NO, ONOO-. Western blot was conducted to assess the protein expression levels of NF-κB (p50, p65), IKK-α, phospho-IκB-α, inflammation-related proteins, COX-2, iNOS, IL-1β, VCAM-1. PH inhibited H₂O₂-treated cell death dose-dependently. It reduced the generation of ·O₂-, NO, ONOO- and PGE₂ in the H₂O₂-treated renal epitheial cells(LLC-PK₁ cell) of mouse in vitro. PH reduced the expression of NF-κB, IKK-α, phospho-IκB-α, COX-2, iNOS, IL-1β and VCAM-1 genes through means of decreasing activation of NF-κB signaling as well. According to these results, PH has an antioxidative activity and anti-inflammatory effect by regulating the NF-κB pathway. This suggest that PH is expected to be used to regulating inflammatory process and treating inflammation-related disease.

Froth flotation of complex copper ore from Indonesia Jambi mine has been carried out to produce high-grade Cu concentrate. Since the ore contained minor Cu sulfides in addition to major Cu carbonate (malachite), copper concentrate was recovered by two-stage process of flotation, which consisted of copper sulfide flotation using xanthate followed by copper oxide flotation using oleic acid. The copper sulfide concentrate of 57.5% Cu grade with 9.5% recovery was obtained by copper sulfide flotation under conditions of 300 g/t collector (1 : 1 mixture of xanthate series Aero Promoter 211 and Aero Promoter 242) and pH 6.0 pulp. In subsequent copper oxide flotation on sink products, the concentrate of 30.8% Cu grade with 92.1% recovery was obtained under the conditions of oleic acid 300 g/t, AF65 50 g/t, pH 8.0 and 2 times cleaning. The flotation techniques which can achieve a Cu grade of 36.1% and a recovery of 92.1% have been developed from the two-stage process of flotation.
