This study randomly chose 10 humanity high schools, which are located in Busan and KyoungNam province. We then examined the recognition rate of physical therapy among 378 teachers who were and still are working in the schools. 1. The recognition grade of physical therapeutics between men and women was significantly different with results of 80.7% of men and 69.7% of women(p<0.05). In the case of experiencing physical therapy, 83.6% of people said they knew the physical therapeutics and in the case of the opposite side, the result was also significantly different with a result of 67.8%(p<0.05). 2. We ranked the people on how much they knew about the physical therapeutics among men and women. With men, the actual experience of physical therapeutic came before what they heard from other people. In the case of women, what they heard from other people came first and the actual experience of physical therapeutic came after. According to the public information from Inje University, the recognition grade is recorded in the 3rd grade department as 21.5% while in the case of experiencing treatment from a physical therapist, the result was 39.1%. In the other department (the 1st grade department), what men and women heard from mass media was recorded at 17.5% and what they heard from other people, it was recorded at 33.8%(p<0.05). 3. The research about the recognition of academic ability of being a physical therapist was that 55.6% of teachers thought that 3-year-college was the best, which made the results different from the recognition grade of the experience of education(p<0.05). 4. In the recognition grade of physical therapeutics, there were significantly differences from 50.2% of men and 45.2% of women were expecting about 1mil ion won to 1.99million won. In case of 25.2% of people who have experience less than 15years at work, they expected about 2million to 2.99million won. The figures were higher than 10.1% of people who have experiences over 15years. About the recognition grade of physical therapists social level in the future is 48.8% of people who had experienced of physical therapy and 63.8% of people who never had experienced of it said it would be better in the future. From these results, the recognition about physical therapeutics and the view of its social status are optimistic and they know well about the level of academic ability of physical therapists. On the other hand, most teachers don't know exactly about physical therapists work. So we have to inform them aggressively for enhancing the recognition of physical therapy because high school students are well affected by their teachers when they face their future or major in university.

Purpose: Infection remains the main cause of morbidity and mortality in liver transplantation (LT) recipients; however infection is notoriously difficult to diagnose because its usual signs and symptoms of infection may be masked or absent. This study comprises an analysis of bacterial infections in the early period after LT. Methods: This is a study of 129 adults who underwent LT from January 2013 to December 2013, and it includes patients who were followed daily from the day of transplantation to 1-week posttransplantation using bacteriological cultures of blood, urine, sputum, and drained ascites. Results: The following factors were significantly different between the positive and negative culture groups: living donor LT vs. deceased donor LT (odds ratio [OR], 3.269; P = 0.003), model for end-stage liver disease score (OR, 4.364; P < 0.001), and Child-Pugh classification (P = 0.007). Neither positive culture nor negative culture was associated with infection within 4 weeks of surgery (P = 0.03), and most events were due to surgical complications (75%). Conclusion: Since the full effect of immunosuppression is not yet present during the first month after LT, we suggest that the number of bacterial culture test could be reduced such that they are performed every other day depending on patient’s situation

This study was conducted to identify transition characteristics of arsenic (As), cadmium (Cd), and lead (Pb) and to calculate bio-concentration factors (BCF) in the three perennial root medicinal plants, namely Codonopsis lanceolata (Deoduck), Platycodon grandiflorum (Balloon flower) and Panax ginseng (Korean ginseng) grown in major medicinal plant producing districts in Korea. Average BCF values ranged from 0.009~0.029 in As, 0.334~1.453 in Cd, and 0.021~0.023 in Pb in three perennial root medicinal plants. The BCF values increased in the order of ginseng (0.029) > deodeok (0.012) > balloon flower (0.009) for As, balloon flower (1.453) > deodeok (0.685) > ginseng (0.334) for Cd, and ginseng (0.023) > deodeok (0.022) > balloon flower (0.021) for Pb. The BCF values calculated in this study will be useful for predicting the uptake of heavy metal (loid)s. Further study on uptake and accumulation mechanism of toxic metal (loid)s by agricultural products is required to assess the human health risk associated with soil contamination.

Coprinopsis cinerea was employed to investigate the fungal response to gravity. Mycelium growth revealed a consistent growth pattern, irrespective of the direction of gravity (i.e., horizontal vs. perpendicular). However, the fruiting body grew in the direction opposite to that of gravity once the primordia had formed. For the proteomic analysis, only curved-stem samples were used. Fifty-one proteins were identified and classified into 13 groups according to function. The major functional groups were hydrolases and transferases (16%), signal transduction (15%), oxidoreductases and isomerases (11%), carbohydrate metabolism (9%), and transport (5%). To the best of our knowledge, this is the first report on a proteomic approach to evaluate the molecular response of C. cinerea to gravity.

Background: Transdermal drug delivery systems provide more reliable and consistent administration than oral routes because they avoid the effects of digestive degradation and first-pass liver metabolism. However, penetration of any compound through the skin is prevented primarily by the epidermis. Objectives: We assess the efficacy of a novel fabric for drug delivery, with the aim of developing an improved method for transdermal drug delivery. Methods: Guinea pigs were divided into a control group and three test groups; treated with slimming cream and no fabric, 100% cotton fabric, or our novel fabric. The amount of fat loss was evaluated by histological staining. The skin penetrance of rhodamine B base was assessed using a fluorescence penetration test and the transdermal penetration of caffeine was also evaluated in vitro using Franz diffusion cells each. Results: Drug delivery with our novel fabric resulted in reduction in adipocyte size after 28 days. The fabric also enhanced the transdermal delivery of rhodamine B base and caffeine penetration compared with the control groups. Conclusion: Our novel drug delivery fabric is an effective way to enhance the transdermal delivery of slimming cream. This fabric can potentially be used to enhance the transdermal delivery of several agents, including drugs.

Purpose: Long-term results following bariatric surgery compared to conventional treatments has never been reported in morbidly obese Korean patients. This study aimed to evaluate the long-term efficacy of bariatric surgery in morbidly obese Korean patients compared to conventional medical treatments. Methods: In this multicenter retrospective cohort study, we reviewed 137 obese subjects between January 2008 and February 2011 with a body mass index (BMI) > 30 kg/m2 who had more than 5 years of follow-up clinical data after bariatric surgery (surgery group, n = 49) or conventional treatment (conventional treatment group, n = 88). Anthropometric data and the status of comorbidities were compared between the 2 groups. Results: The median follow-up period was 72.1 months (range 19.3–109.7 months). At the last follow-up, the surgery group showed a greater amount of total weight loss than the conventional treatment group (24.9% vs. 2.8%, P < 0.001). The prevalence of diabetes and hypertension significantly decreased in the surgery group, while the conventional treatment group showed a marked increase in these comorbidities. In the surgery group, Roux-en-Y gastric bypass and sleeve gastrectomy achieved comparable long-term weight loss (26.5% vs. 22.4%, respectively; P = 0.087). Conclusion: In the long-term, bariatric surgery achieved and maintained significantly greater weight reduction, as well as a decrease in obesity-related comorbidities, than did conventional medical therapy in morbidly obese Korean patients
