OBJECTIVE To assess the effect of vision in three dimensions (3D) versus two dimensions (2D) on mental workload and laparoscopic performance during simulation-based training. MATERIALS AND METHODS A prospective, randomized crossover study on inexperienced students in operative laparoscopy was conducted. Forty-six candidates executed five standardized exercises on a pelvitrainer with both visi...

This study aims to verify the clinical treatment effect of Sandplay Therapy (SPT) through MMPI-2 for 22 adolescents who have experienced suicidal events such as suicide attempts, accidents, and self-injury. To this end, 20 weeks from 2019 2021, SPT 15 sessions were conducted teenagers cases at middle high schools in Cheonan Asan. The subjects 6 males (27.3%) 16 females (72.7%) with an average a...

OBJECTIVE To determine the biochemical effects of restricting the use of chloride-rich intravenous fluids in critically ill patients. DESIGN Prospective, open-label, before-and-after study. SETTING University-affiliated intensive care unit. PATIENTS A cohort of 828 consecutive patients admitted over 6 months from February 2008 and cohort of 816 consecutive patients admitted over 6 months ...

The association between acne and food has been evaluated with inconsistent results. We enrolled 783 patients with acne and 502 control subjects. For the patients with acne, blood tests for insulin, insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3), post prandial 2 hours blood glucose (PP2), and dehydroepiandrosterone sulphate (DHEAS) were performed. Th...

The microscopic structure of the GaP(001) surface is not well understood, in marked contrast to other III–V compounds, in particular GaAs(001) (see Ref. [1] for a recent review). It has been suggested that ion bombardment and annealing of GaP(001) results in a (4 2) reconstructed Ga-rich surface [2, 3] in analogy to GaAs. On the other hand, based on ion scattering spectroscopy and low-energy el...

The purpose of the current study was to investigate whether or not the FABP2 gene polymorphism modulated obesity indices, hemodynamic factor, blood lipid factor, and insulin resistance markers through 12-week aerobic exercise training in abdominal obesity group of Korean mid-life women. A total of 243 abdominally obese subjects of Korean mid-life women voluntarily participated in aerobic exerci...

Evidence • A 2007 systematic review (26 studies, 2767 patients) assessed the use of pedometers to increase physical activity levels and improve health1: -Pedometers increased the mean steps per day by 2491 in randomized controlled trials (P < .001) and 2183 in observational studies (P < .0001). -Having a “step goal” (most commonly, working up to 10 000 steps a day) predicted increased activity ...

The purpose of this study was to examine whether physical activity (PA) and sedentary behavior were related to weight status in Korean adolescents. A total of 72,399 students in Grades 7-12 participated in the 5th Korea Youth Risk Behavior Web-Based Survey (KYRBWS-V) project in 2009. Body mass index, PA, and sedentary behavior were assessed by the KYRBWS-V. The study results show that boys had ...

BACKGROUND Chronic opioid therapy for pain management has increased dramatically without adequate study of potential deleterious effects on breathing during sleep. METHODS A retrospective cohort study comparing 60 patients taking chronic opioids matched for age, sex, and body mass index with 60 patients not taking opioids was conducted to determine the effect of morphine dose equivalent on br...

BACKGROUND Regular physical exercise and healthy lifestyle can improve aerobic power of the elderly, although lung capacity gradually deteriorates with age. The aims of the study are: a) to evaluate the therapeutic effect of a treadmill exercise program on arterial blood oxygenation (SaO2), maximum oxygen consumption (VO2max) and maximum walking distance (MWD) in healthy elderly people; b) to e...
