Purpose: The exercise status in patients with rheumatoid arthritis, associations between exercise behavior and personal factors, and associations between exercise behavior and exercise-specific cognitions and their effects were assessed. Method: Four hundred thirty nine outpatients with rheumatoid arthritis were studied. The exercise status was measured by a single item. The intensity was multiplied by the frequency and duration of each exercise. The product of these intensity values for all exercises was defined as exercise behavior. Based on the Pender's revised health promotion model, exercise benefit, barrier, self-efficacy, enjoyment and social support were chosen as exercise specific cognitions and affect variables. Path analysis was used to identify the predictors of exercise behavior. Results: Compared to the duration before being diagnosed, the number of subjects who exercised regularly increased after being diagnosed. However over half of the subjects refrain from any sort of exercise and the type of exercise is very limited. Among the variables, exercise barrier, self-efficacy, and social support were found to be significant predictors of exercise behavior, and only previous exercise experience was found to be significant predictors of all behavior specific cognitions and affect variables. Conclusion: These findings suggest that studies should explore exercise behaviors and strategies to emphasize the cognitive-motivational messages to promote exercise behaviors.

Increasing the old and the senile disability, it is increased that the demand of barrier-free house for the disabled, the senior, the pregnant and the young is strongly increasing recently. In this reason, this study focuses the problems of the house which is used by the Blind through the investigation of current status and tries to find out the differences between disability's demand and current design of their house. As well, through the research and analysis some cases of the residential alterations this study verifies what the demand is on each room and their need is committed correctly during the residential alterations. It is the purposes of this study finding the problems through these research and analysis. Thus this study investigates houses of the Blind and finds out their house type, scale and daily life through the statistical data and documentary survey and also, investigates current status of their house. The basic standard for the current status and the demand analysis is researched by the barrier factors which are deducted from the former study.

In the developing brain, capillaries are differentiated and matured into the blood-brain barrier (BBB), which is composed of cerebral endothelial cells, astrocyte end-feet, and pericytes. Since the BBB regulates the homeostasis of central nervous system (CNS), the maintenance of the BBB is important for CNS function. The disruption of the BBB may result in many brain disorders including brain tumors. However, the molecular mechanism of BBB formation and maintenance is poorly understood. Here, we summarize recent advances in the role of oxygen tension and growth factors on BBB development and maintenance, and in BBB dysfunction related with brain tumors.

Purpose: Perceived barriers to exercise were investigated for adults. Method: A total 1266 subjects were selected by a quota sampling method with age, gender, and residence. Perceived barriers were categorized under 4 groups: knowledge, psychological, physical, and external factors. All 23 items of perceived barriers were responded on a dichotomous (yes/no) scale. Result: Mean number of perceived barriers was 4.61 and 87.9% subjects perceived at least one barrier which prevented involvement in exercise. External barriers ranked highest, followed in order by psychological, knowledge, and physical barriers. Most factors of perceived barriers were found to be different by age, gender, and residence, in that, the younger, female, living in Daejeon subjects were found to respond with more barriers than the older, male, living in Chungju or Seoul. Conclusion: Perceived barriers to exercise are differenct by age, gender, and residence. Therefore, it is recommended that age, gender, and residence of subjects must be considered in order to develop exercise programs and public campaigns.

Purpose: The purpose of this study was to investigate factors that have influence on a health examination among the middle aged living in Busan. Method: The survey was conducted with 235 participants who were the parents of students of five nursing schools in Busan, living in Busan, and subjects to a health examination under the National Health Insurance Corporation. The data was collected from September to November 2004 using a structured self-administered questionnaire that contained general characteristics, characteristics related to a health examination, and health belief variables. Collected data were analyzed using SPSS/WIN 10.0. Results: Among the subjects, 122(51.9%) had performed a health examination in the past, and 113(48.1%) had not. Variables that have a significant influence on getting a health examination were: previous disease experience, perceived barrier and perceived seriousness. Those who did not have previous disease experience(2.6 times) and whose perceived seriousness was high(1.1 times) were more likely to have a health examination, and those with perceived barrier high(0.9 times) were less likely. Conclusion: Therefore, to increase the rate of health examinations, it is necessary to advertise the importance of health examinations particularly for the people who had disease experience and the seriousness of target diseases; and furthermore, to remove barriers of a health examination.

Purpose: The purpose of this study was to identify community health practitioners' (CHP) perception of barriers to research utilization, current status and competence in evidence-based practice (EBP). Methods: From all over the country, 126 CHP completed an e-mail survey. Results: The items with the highest barrier scores were that it is difficult to understand articles written in English and physicians will not cooperate with implementation. There were statistically significant differences in the scores for attitude toward EBP and knowledge in EBP by education level and nursing academic society membership status. When faced with a problem, the nurses usually use related regulations or asked a colleague for advice. Conclusion: Results indicate an awareness of the necessity of applying EBP, need to improve readiness to use EBP voluntarily and actively, and need to search for various factors that are barriers to research utilization. There is a need to develop and apply EBP training/education programs to find new evidence that might actually support previous practice for which nurses lack confidence. Guidelines that consider CHP task characteristics and barrier factors to research utilization should be developed.

Smart phones become essential goods for our life. As the technology are developing, and the market becomes saturated, it is important to understand the determinants affecting purchase of smart phones. In this paper, to understand these determinants factor analysis and binary logistics regression is used. Toward this, we first define the determinants into 3 categories: customer satisfaction, switching barrier, and switching attractiveness based on literature review. Furthermore, we develop 9 hypotheses to test with survey data using factor analysis and binary logistics regression. The results show that the six factors (data quality, price satisfaction, corporate image, the burden of new contract, attraction of devices and attraction of other competitors) are significant when customers buy smart phones.

Physicochemical factors affecting cooking and eating quality of rice and their mechanisms were investigated. The stickiness of cooked rice was negatively correlated with amylose content(r=0.58, p<0.05) and protein content(r=-0.72, p<0.01), but not affected by crude fat content of rice. The ultrastructure of cooked rice grain showed the progressive gelatinization of starch from the periphery toward the center of the endosperm as water and heat energy diffused into. The rate of water diffusion appears to be dependent on the cell arrangement in the endosperm and the protein content of milled rice. Once water and heat reach the starch granules, the rate of in situ gelatinization of starches appears to be dependent on their own gelatinization temperature range and amylose content. Protein acts as a barrier for the swelling of starch and water diffusion in two ways : 1) by encasing starch granules in the starchy endosperm, and 2) by forming a barrier between the subaleurone layer and the starchy endosperm. Therefore, the separation and fragmentation of the outermost layers of the endosperm occurred more easily in the low-protein content rices, and was associated with increases of solids lost in cooking-water at 95$^{\circ}C$ and stickiness of cooked rice.

Atopic dermatitis (AD) is a common and multifactorial inflammatory skin disease that is characterized by skin barrier dysfunction, inflammation, and chronic pruritus. AD has a complex etiology that includes genetic, immunological, and environmental factors that cause skin barrier abnormalities and immune dysfunctions. Sophora flavescens (SF) has been used in traditional Chinese medicine, but little research has been conducted on its anti-AD efficacy. In this study, we evaluated the effect of SF extract (SFE) on improving skin barrier function and immune abnormalities, which are the main symptoms of AD. SFE has the capacity to enhance the formation of cornified envelope (CE) that plays an important role in the skin barrier function. In addition, it was confirmed that SFE increased the expression of hyaluronic acid related to skin moisture. The effect of SFE against Staphylococcus aureus (S. aureus), which increases specifically in AD lesions, confirmed that SFE inhibited the production of pro-inflammatory cytokines induced by S. aureus. Furthermore, SFE was shown to inhibit the expression of pro-inflammatory cytokines induced by substance P (SP), the cause of skin neurogenic inflammation. These results demonstrate that SFE could be one of potential candidate agent for the treatment of AD by improving the skin barrier function and immune responses.

The purpose of this study is to examine the degree of health promotion behavior among stomach cancer patients and its relevant factors, such as belief, family support, and self-esteem etc. To investigate factors affecting health promotion behavior among stomach cancer patients, a survey was conducted through personal interviews with 153 stomach cancer patients who came to two hospitals in Daejeon from June to July, 2008. Questions were about respondents' general characteristics, properties related to stomach cancer, health belief & family support for the disease, and self-esteem. According to the results of multi-variate regression analysis, factors affecting health promotion behavior included age, treatment type, benefit, barrier, family support, and self-esteem which explained 66.6%. Public health and medical interventions are necessary to improve health promotion behavior among stomach cancer patients by improving benefit, family support, and self-esteem and reducing barrier.
