Purpose: Aspiration pneumonia (AP) is the major complication of dysphagia in patients with acute stroke. Nursing management for dysphagia influences on patients' health outcomes. The purpose of this study was to develop and evaluate the effects of Dysphagia Nursing Protocol (DNP) for patients with acute stroke. We aimed to examine the incidence of AP and the dependency rate at the discharge. Methods: We used a non-equivalent control group posttest only design in this study. DNP was developed with content validity index > 0.75 in all items. This protocol was composed of the evaluation, education, complication prevention, and checking phases. After training the staff nurses, we applied DNP protocol to the experimental group. The control group was enrolled from June to August 2013 (n=80), and the experimental group was June to August 2014 (n=64). Results: The incidence of AP was 16.3% in control group while 4.7% in experimental group (p=.028), and the Odds Ratio (OR) was 0.26 (p=.045). The dependency ratio was 66.3% in control group while 43.8% in experimental group (p=.011), and the OR was 0.33 (p=.011). Conclusion: DNP was beneficial for the reducing the risk of AP and the improved the functional status.

We investigated the effects of dietary supplementation of two types (powder or liquid) of propolis on innate immunity and disease resistance of olive flounder Paralichthys olivaceus against Edwerdsiella tarda. A total of 600 fish averaging 30 g were randomly distributed into 24 tanks in groups of 25. Three tanks were assigned to each of eight experimental diets: 0 (Control), 0.25, 0.5, 0.75 and 1 % propolis in powder form and 0.25, 0.5 and 1 % propolis in liquid form (PP0.25, PP0.5, PP0.75, PP1, LP0.25, LP0.5 and LP1, respectively). Fish were fed each experimental diet twice daily for four weeks to apparent satiation. At the end of the feeding trial, lysozyme and myeloperoxidase activities and total immunoglobulin level were significantly higher in fish fed the PP1 and LP0.5 diets compared to those fed the control diet. The PP1 diet was also associated with a significant increase in anti-protease activity compared to the control diet. After challenge with E. tarda, fish fed the LP0.5 diet showed numerically higher survival compared to the other groups. This study indicates that non-specific immune responses of olive flounder can be enhanced by dietary supplementation with powder and liquid forms of propolis, and that the optimal level would be 1% in powder form or 0.5% in liquid form. It seemed that growth performance and feed utilization are not affected by the propolis supplementation in diets for olive flounder.

The activity to share personal daily life through social media is becoming more common. In this case, photographs as well as text are used a lot; it has been as easy as winking to clip others' photographs just as it's very easy to take and post pictures. If the picture is the photographic work protected by the copyright law, however, the clipping should be paid close attention. If you use others' photographic works without authorization, you infringe their copyright; if you post them on your social media such as blog, you infringe the right of reproduction, interactive transmission and exhibition. Even though the clipping is permitted, if you'd like to use the photographic works for a profit-making purpose, you should get additional authorization. Others' photographic works are occasionally altered and used for the purpose of avoiding the argument in relation to the infringement of copyright; this act means that it's the infringement of the right of reproduction, the right to preserve the integrity and the right of the production of derivative works for degrees of alteration. We can download others' photographic works with a few mouse clicks thanks to the technology of capturing the screen; we have to recognize that all the acts technically possible are not always legal.

This study is to provided a basic model to encourage environment and outdoor play programs. The study was based on the analyses of actual activities performed in two child care centers in Daejeon area and the way in which the programs for outdoor play were related to the environment of the centers. Data were collected through 'The Daily Report of the Outdoor Play Programs: Plan and Evaluation' paper conducted at each center performed from 2007 to 2009. Following Mockwha Choi et al., (2007), the play observed and described by teachers was analyzed to classify play areas and play activities within each area. The places, equipment and, playthings using in each play period were also examined as well as the limitation and inspiration caused by the environment. The results of the study are as follows: 1) Empty and unfilled space tended to generate more types of non-structural play and role-pretend play 2)Adventurous play was rarely observed. More thoughtfully designed physical environments need to be provided for children to experience challenge and adventure through physical activities 3) Outdoor play environment should be suitable for the overall developments of infants and toddlers depending on their activities. A child care specialist should support the design such environment 4) Naturally, the programs of outdoor play will not be identical for all child care centers. Rather, they should go along with the programmatic characters and environmental attributes of each center. Therefore the awareness of teachers and parents as to the importance of must realize of outdoor play should be further increased.

The purpose of this study was to determine the extent of oxidative stress in NIDDM patients with diabetic complications and to determine the relationship between oxidative stress and diabetic complications. For this study, 139 NIDDM patients were recruited, 85 with diabetic complications and 54 without complications were recruited. The concentration of malondialdehyde(MDA) and the activities of antioxidant enzymes including catalase, superoxide dismutase(SOD), gluthatione peroxidase(GSH-Px)were determined. The daily intakes and plasma concentrations of beta-carotene, lycopene, lutein nd alpha-tocopherol were determined by food frequency questionnaire and by high performance liquid chromatography(HPLC), respectively. Among the antioxidant enzymes studied, only GSH-Px activity was lower in NIDDM patient, with diabetic complications than in those without complications(2.91$\pm$0.80 vs 3.54$\pm$0.44 U/mgHb, p<0.05). Those NIDDM patients with diabetic complications had higher MDA concentrations than those without diabetic complications(1.40$\pm$0.25 vs 1.25$\pm$0.11 nmol/ml, p<0.05). There were no significant differences in the dietary intakes of total carotenoids(2854 vs 2824ug/day)or vitamin E (9.5$\pm$3.2 vs 9.5$\pm$2.0mg/day)between NIDDA patients with and without complications. However, the plasma concentrations of beta-carotene and lycopene were significantly lower in NIDDM patients with complications than in NIDDM patients without complications (Beta-carotene : 24.2$\pm$12.5 vs 33.1$\pm$16.2(ug/dl), lycopene : 2.8$\pm$2.1 vs 4.3$\pm$2.8(ug/dl)). This study showed that in NIDDM patients with complications, the lipid peroxidation of erythrocytes was higher increased and the antioxidant reserves were significantly dipleted, compared with NIDDM patients without complications. The lower plasma concentrations of beta-carotene and lycopene in NIDDM patients may be due to the presence of diabetic complication, not due to the lower dietary intakes of antioxidant vitamins. To define the role of carotenoids in diabetes, more experimental and clinical studies are needed.

Purpose: The purpose of this study was to compare sociodemographic characteristics of a normal cognitive group and mild cognitive impairment group, and establish prediction models of Mild Cognitive Impairment (MCI). Methods: This study was a secondary data analysis research using data from "the 4th Korea Longitudinal Study of Ageing" of the Korea Employment Information Service. A total of 6,405 individuals, including 1,329 individuals with MCI and 5,076 individuals with normal cognitive abilities, were part of the study. Based on the panel survey items, the research used 28 variables. The methods of analysis included a χ²-test, logistic regression analysis, decision tree analysis, predicted error rate, and an ROC curve calculated using SPSS 23.0 and SAS 13.2. Results: In the MCI group, the mean age was 71.4 and 65.8% of the participants was women. There were statistically significant differences in gender, age, and education in both groups. Predictors of MCI determined by using a logistic regression analysis were gender, age, education, instrumental activity of daily living (IADL), perceived health status, participation group, cultural activities, and life satisfaction. Decision tree analysis of predictors of MCI identified education, age, life satisfaction, and IADL as predictors. Conclusion: The accuracy of logistic regression model for MCI is slightly higher than that of decision tree model. The implementation of the prediction model for MCI established in this study may be utilized to identify middle-aged and elderly people with risks of MCI. Therefore, this study may contribute to the prevention and reduction of dementia.

The concept of biostimulation of wounds by low-level laser therapy(LLLT) is attracting considerable attention. Although its effect on whole tissues has been studied quite extensively, the biological and cellular mechanisms underlying LLLT have not been clarified. In an experimental radius fracture in rabbits, Tang and Chai reported that LLLT enhanced the activity of red blood cells, macrophages, fibroblasts, chondrocytes, and osteoclasts within the fracture area. The purpose of the present study was to evaluate the effect of LLLT with a GaAlAs diode laser device on bone healing in rabbit mandibular fractures. We use 12 rabbits for this study. All rabbits were fractured mandible angle area using saw in anesthetic condition. In control group(n=6), none treatment was performed at fracture site. In experimental group(n=6), LLLT with a GaAlAs diode laser was radiated at fracture site daily for 7 days. All rabbits were sacrificed at 6 weeks later from performed fracture day. We studied the immunohistochemical staining of CD34 and Vimentin and the histochemical analysis for calcium and phosphorus content. The results were as follows. 1. In the histological and immunohistological staining, after 6week, fibroblasts, osteogenic cells and collgen fibers were observed more in experimental group than in control group. 2. In the histochemical analysis, the amount of calcium and phosphorus contents of the experimental group were more than the control group. From the results obtained, we suggest that the bone healing is stimulated by low-level laser irradiation in bone fractures.

Low back pain is often experienced by many people who are in an activity flag. Their work and daily life are affected by low back pain. There are many causes of low back pain. Among those many causes, this study was focused on a relation between low back pain and the tightness of iliopsoas. The study was implemented by measuring the angles of the hip joints in subjects consisting of a 30 patients group, who had been selected from the outpatients at the Median Hospital, and a 30 people control group from the outpatients at the M Hospital and employee of M hospital. The patients group consists of the patients with low back pain who have intermittently or continuously experienced low back pain within the last 6 months. The group also had no symptom of spondylolysis or spondylolithesis and no muscular abnormality in terms of pathology without any experience of disc or spine fusion operation. The control group consisted out of persons who had never experienced lower back pain and had never been subjected to physical therapy due to lower back pain. The hip joint angles of the subjects of this study were measured by means of the modified Thomas test position. Data was analysed by independent sampling t-test using SPSS 11.0. The following results were obtained: 1. The measured angles of patient's both hip joints were significantly smaller than the control group's. 2. In the males group, The angles of patients' both hip joints were smaller than the controls'. In the females group, The angles of patients' both hip joints were smaller than the controls'. In conclusion, this study demonstrates that there is a significant difference in the tightness of the iliopsoas muscles when comparing the patient group with the control group. We should therefore pay more attention in releasing the muscle tightness of iliopsoas muscles when performing physical therapy with patients with lower back pain.

The Internet has brought many changes in our daily lives. Now the recognition on the Internet fashion shopping matt has increased and it requires scientific and systematic research to understand the Internet fashion marketing system more correctly and to strengthen the marketing activity at the virtual space. A big shortcoming of an Internet fashion mall is that the consumers can't wear clothes themselves. Currently there is no system to cover the shortcoming, It would be nice if a 3D avata wears the clothes on behalf of a consumer after inputting the information of physical sizes of a consumer. The consumers can select many clothes, accessories and even the background. After establishing a complete virtual fashion shopping mall, the consumers who sue the Internet fashion shopping mall could wear the clothes at an online shop establishing an online shopping environment. It will be a sole way to ensure the trust of the consumers. This paper studies the read in reflection by PC camera and sample the edge detection. Virtual fitting system that wears virtual fitting model some clothes is establishment.
