Objective: The aim of this study was to explore the effect of physical activity and metabolic parameters on irisin levels in patients with schizophrenia and healthy controls. Methods: Ninety-six patients with schizophrenia and 63 healthy controls comprised the study population. The participants were separated into three groups: inactive, low activity, and sufficiently active according to International Physical Activity Questionnaire short form (IPAQ-SF). We measured irisin levels using Enzyme linked immunosorbent assay. We also calculated exercise levels by using the IPAQ-SF for each individual. The independent samples t test was used in the data analysis to compare irisin levels according to the activity levels of the patients with schizophrenia and controls. Results: The levels of irisin were higher in the healthy controls (p < 0.001) compared to schizophrenia groups. When the activity levels of the schizophrenia and healthy control groups were compared, the irisin levels of the low activity and sufficiently active groups with schizophrenia were found to be lower than those of the low activity and sufficiently active groups in the healthy controls (respectively p = 0.014; p < 0.001). Conclusion: Irisin levels could be affected by physical activity and these results must be supported with new studies.

An Experimental Study of Reinforced Concrete Beams with Closely-Spaced Headed Bars

Kah Mun Lam,Woosuk Kim,Michael Van Zandt,Thomas H.-K. Kang 한국콘크리트학회 2011 International Journal of Concrete Structures and M Vol.5 No.2

The use of headed bars as opposed to standard 90- or 180-degree hooked bars in beam ends, beam-column joints or other steel congested areas for anchorage and bond has become more favorable due to the fact that steel congestion is often created by large bend diameters or crossties. This research mainly focuses on evaluating the code provisions regarding the use of headed bars. Nine simply supported rectangular concrete beams with headed longitudinal reinforcement were tested under a four-point monotonic loading system. The design clear spacing, which varies from 1.5 to 4.25 times the bar diameter, was the only parameter for the experimental investigation. The test results showed that the closely-spaced headed bars were capable of developing to full yield strength without any severe brittle concrete breakout cone or pullout failure. Bond along the bar was not sufficient due to the early loss of concrete integrity. However, the headed bars were effective for anchorage with no excessive moment capacity reduction. This implies that the clear spacing of about 2 times the bar diameter for headed bars may be reasonable to ensure the development of specified yield strength of headed bars and corresponding member design strength.

第二蓮花鑛山의 地質鑛床에 對하여

Kah Soo Han(韓甲洙) 대한자원환경지질학회 1972 자원환경지질 Vol.5 No.4

The Second Yeon Hwa Mine which belongs to a so called Lead-Zines Belt Area in the central east Korea is located at about 10 km northeast of the Seogpo railway station on Yeongdong Line. The exploitation of the mine started in June, 1969 and furnished the machinary ore dressing plant in November, 1971. The current monthly production of rude ore is 15,000 meteric tons. The results of the study on the lead-zinc-copper deposits of the Second Yeonhwa mine are summerized as follows: (1) main ore deposits of the mine are localized in the Pungchon Limestion formation of Cambrian age, (2) related ingneous rock with ore deposits is granite porphyry, which distributed in NS and N50˚ W trend, (3) ore solution ascended along the N50˚ W trend which represents folding axis and fault plane and mineralized selectively in the limestone formation. (4) high grade ore deposits are localized in concave and convex boundaries of granite porphyry, and hanging walls of shale bed (P₂S shale bed) in Pungchon Limestone formation and (5) skarn minerals are consisted of garnet, hedenbergite, diopside, and sulfide minerals are composed of zincblenede, galena, phyrhotite, pyrite and some amount of chalcopyrite and arsenopyrite.

The objective of this work was to study the effect of storage temperatures and duration on the stability of fermented red dragon fruit drink (FRDFD) on its betacyanins content, physicochemical and microbiological qualities (BPM) and determining sensory acceptability. Results showed that both storage temperatures and duration have a significant effect on betacyanins content and physicochemical properties of FRDFD. Aerobic mesophilic and yeast and mold counts were lower than 1 9 103 CFU/ mL for FRDFD stored at both temperatures. The loss of betanin (16.53–13.93 g/L) at 4 C was 15.73% with no significant changes in physicochemical properties from week two onwards compared to 56.32% (16.53–7.22 g/L) of betanin loss at 25 C. At week eight, FRDFD stored at 4 C still contained 13.93 g/L betanin with a pH value of 3.46, suggested its potential as a functional drink which is sensory acceptable (mean score[80% using hedonic test) among consumers.

Outcomes of a Multi-Modal Hospital-Associated Home-Based Cancer Prehabilitation Program

Kah Meng Kwok,San San Tay 대한재활의학회 2023 Annals of Rehabilitation Medicine Vol.47 No.1

Objective To assess the impact of a “one-stop”, multi-modal, hospital-associated-home-based prehabilitation model, helmed by a small core team, on newly diagnosed gastrointestinal and urological cancer patients planned for surgery. Methods This is a retrospective study in a tertiary public hospital, involving all newly diagnosed gastrointestinal and urological cancer patients planned for surgery. The primary outcome measure was the 6-minute walk test (6MWT). Other outcomes included physical, psychological and quality-of-life measures, and patient satisfaction surveys, taken at baseline, pre-operatively (post-prehabilitation), and at 3 months post-operatively. Results When comparing the baseline to pre-operatively (post-prehabilitation), there was a statistically significant improvement in the 6MWT (21.52 m, p<0.001), 30-Second Sit to Stand test (STS) (1.08 repetitions, p<0.001), Timed Up and Go test (TUG) (0.83 seconds, p=0.014) and Hospital Anxiety and Depression Scale (HADS) (total score 1.77, p<0.001). These were sustained (6MWT: 0.22, p=0.964; STS: 0.08 repetitions, p=0.863; TUG: 0.04 seconds, p=0.939) or further improved (HADS total score 2.06, p=0.003) at 3 months post-operatively. There was also a statistically significant improvement in the EuroQol-5 dimension health score (health-related quality-of-life measure) from baseline to 3 months post-operatively (7.04 points, p=0.001), with more than 90% overall patient satisfaction reported. Conclusion Prehabilitation applied via our model resulted in significant improvements in functional capacity, psychological and quality-of-life outcomes, sustained at 3 months post-operatively, and is a feasible and effective approach that is well-received by our patients.

Betacyanins are bioactive dietary phytochemicalswhich can be found in red dragon fruit (RDF). Therefore, the bioaccessibility of betacyanins that presentin fermented red dragon fruit drink (RDFD) and pressedred dragon fruit juice (RDFJ) was accessed in simulatedgastric and intestinal digestion. Results disclosed thatbetacyanins from RDFD and RDFJ suffered minor loss(\25%) at gastric-like environment but greater loss wasobserved during the intestinal phase digestion. After subjectedto intestinal digestion, RDFD retained 46.42% ofbetanin while RDFJ retained 43.76%, with betanin concentrationof 17.12 mM and 12.37 mM, respectively. Findings also revealed that RDFD exhibited higherantioxidant capacity compared to RDFJ after subjected tointestinal digestion, with values of 0.88 mM Troloxequivalent antioxidant capacity (TEAC) and 0.85 mMTEAC, respectively. The data suggests that betacyaninsthat present in RDF are bioaccessible while fermentationable to enhance the bioavailability with more betacyaninsretained after intestinal digestion.

Is All Politics Local?

This paper analyzes the extent to which performances of the national and local governments could shape local election outcomes. Specifically, we use two waves of the survey data of Taiwan’s Elections and Democratization Studies (TEDS) to explore whether one’s assessments of the local and central governments’ performances affect his/her choice between county magistrate/city mayor candidates. Our findings verifies three hypotheses suggested by the previous literature: first, voters with positive assessment of the local government’s performance are more likely to vote for incumbent; second, local elections can be regarded as referenda on the central government; and third, in local elections, the impacts of local/central government approval ratings on vote choice depend on whether the elections are open seat contests or incumbent races.
