The purpose of this article was to examine the influence of physical environment on customer's buying-risk perception at franchise Korean restaurants. In this research factor analysis and multi regression analysis were used. Physical environment were divided to 3 factors and risk perception to 5 factors. Internal environment affected negatively financial risk (p<0.001), time risk (p<0.001) and psychological risk (p<0.001). External environment had negative influence on time risk (p<0.05) and psychological risk (p<0.05). And the other environment negatively affected financial risk (p<0.001), time risk (p<0.001) and psychological risk (p<0.05). According to these results, we confirmed that various physical environments influenced on the risk perception of customers. As a result, food service corporations need to deal with physical environment efficiently. And the findings of this research would help their business management to build effective service marketing strategies and to satisfy the needs of customers at franchise Korean restaurants.

Understanding the crosstalk mechanisms between perivascular cells (PVCs) and cancer cells might be beneficial in preventing cancer development and metastasis. In this study, we investigated the paracrine influence of PVCs derived from human umbilical cords on the proliferation of lung adenocarcinoma epithelial cells (A549) and erythroleukemia cells (TF-$1{\alpha}$ and K562) in vitro using $Transwell^{(R)}$ co-culture systems. PVCs promoted the proliferation of A549 cells without inducing morphological changes, but had no effect on the proliferation of TF-$1{\alpha}$ and K562 cells. To identify the factors secreted from PVCs, conditioned media harvested from PVC cultures were analyzed by antibody arrays. We identified a set of cytokines, including persephin (PSPN), a neurotrophic factor, and a key regulator of oral squamous cell carcinoma progression. Supplementation with PSPN significantly increased the proliferation of A549 cells. These results suggested that PVCs produced a differential effect on the proliferation of cancer cells in a cell-type dependent manner. Further, secretome analyses of PVCs and the elucidation of the molecular mechanisms could facilitate the discovery of therapeutic target(s) for lung cancer.
Purpose : Impaired glucose tolerance (IGT) was standardized in 1979 by the National Diabetes Data Group and the World Health Organization as a risk factor for type 2 diabetes, replacing groups such as 'borderline' and 'chemical' diabetes. The main clinical significance of IGT is as a risk factor for type 2 diabetes and as a risk factor for cardiovascular disease and as a component of the metabolic syndrome. In 1997 the American Diabetes Association(ADA) was proposed the new classification and diagnostic criteria for diabetes, which is strict with the diagnostic baseline of Diabetes from 140mg/dl to 126mg/dl. And it's main purpose is to prevent chronic complications by early diagnosis and treatments. In the oriental medicine, Supungsunkihwan has been used in treatments of Diabetes including IGT & NIDDM, however there is not enough studies about the its objective hypoglycemic effect. so in order to investigate whether there is hypoglycemic effect of Supungsunkihwan, clinical studies were performed with IGT and mild NIDDM patients. Methods : Prior to the study, fasting blood sugar(FBS) and postprandial 2hrs(PP2hrs) glucose were checked. In addition, ECG, cholesterol, TG, HbA1c levels were measured, and the dinical characteristics of patients that can be influence to the blood sugar level such as age, gender, rest type, diet type were surveyed. Supungsukihwan was administered for 7 days, and FBS & PP2hrs were measured again after the therapy. Result : PP2hrs glucose levels were decreased by the administration of Supungsunkihwan. And It's hypoglycemic effects has the correlation with age. That is, the more age increase, the more hypoglycemic effect decrease. Conclusion : Supungsukihwan has hypoglycmic effects on IGT & mild NIDDM patients and it is more effective when administrated to young patients relatively.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation and results from environmental factors and genetic factors. Although cigarette smoking is a major risk factor, other environmental exposures can influence COPD. The purpose of this study is to investigate the clinical characteristics of COPD according to the history of environmental exposure. Methods: The study population comprised of 347 subjects with COPD who were recruited from the pulmonary clinics of 14 hospitals within the Korean Obstructive Lung Disease Study Group. We classified environmental exposures according to history of living near factory, and direct exposure history to firewood or briquette. According to living environmental exposures, we compared the frequency of respiratory symptoms, pulmonary function, quality of life, exercise capacity, and computed tomography phenotypes. Results: Thirty-one subjects (8.9%) had history of living near factory, 271 (78.3%) had exposure history to briquette, and 184 (53.3%) had exposure history to firewood. Patients with history of living near a factory had a significantly longer duration of sputum, while patients with exposure to firewood tended to have lower forced expiratory volume in one second, and patients with exposure to briquette tended to have lower six minute walk distance. Conclusion: COPD subjects with the history of living near factory had more frequent respiratory symptoms such as sputum. Our data suggest that environmental exposure may influence clinical phenotype of COPD.

The higher the firm performance, the more chances enterprises can expand and develop their production, create jobs, and improve the workers' living quality. The main objective of this study was to measure the internal factors influencing the firm's performance of food and beverage (F&B) firms listed on the Hanoi Stock Exchange (HNX). Data was collected on 15 F&B firms listed on the HNX from 2015 to 2019 We use mixed research method, both qualitative and quantitative. For the quantitative research method, the supporting tool is Stata13 software. The results via Ordinary Least Squares (OLS) regression method show the impacts of internal factors with the following observed variables: the ratio of short-term debt to total liabilities (CS1) and total assets (S2) have an opposite impact (-) on ROA and ROE; debt-to-total assets ratio (CS2) has an opposite effect (-) on ROA; growth of total assets (G2) of the growth factor positively affects (+) ROA and ROE, the remaining factors do not affect ROA and ROE; and internal factors do not influence ROS. Based on the findings, some recommendations have been proposed to help the F&B firms listed on the Hanoi Stock Exchange improving their firm performance in the future.
This study conducted to find influences of selection attributes on consumer satisfaction as perceived by low-cost restaurant visiter by considering personal value. Developed survey was distributed and 428 sample who visited the low-cost franchise restaurant were employed the statistical analyze. The internal value and the external value included individual value in order to estimate the influence of the choice factor of the low-cost franchise restaurant on the quality of the product, and the choice factors were consisted of 3 variables that are quality, accessibility and service. Regression analysis was conducted to verify the relationships among the variables. As a result, the internal value (${\beta}=.236$, p<.0.01), and external value (${\beta}=.352$, p<.001) have the significant positive relationships with respect to quality. Second, the external value (${\beta}=.305$, p<.001) has the positive relationship with regard to accessibility, but the internal value has no significant relationships with level of accessibility. Third, the internal value (${\beta}=.828$, p<.001) has the significant positive relationship with regard to service, but there was no significant influences between external value and service in this study. Fourth, the internal value (${\beta}=.472$, p<.001), the external value (${\beta}=.479$, p<.001) were critical antecedents of the quality. Last, while quality (${\beta}=.858$, p<.001) has significant positive relationship with satisfaction, but it didn't show any relationships with accessibility and service.

The article is devoted to analyzing the police influence on road safety formation. The globalization processes confirm the study's relevance, provoking population mobility and the need to increase freight traffic. The study aims to identify the factors that affect road safety and the activities of the police and the EU transport safety units. An empirical analysis using factor analysis, correlation analysis, and general scientific methods of cognition were carried out to achieve the goal. The analysis results found that the number of police officers affects road safety, but not in all countries, which confirms the importance of other factors. Based on the analysis results of the scientific literature, the factors affecting transport safety are legislative regulation, the use of innovative technologies, transport infrastructure, geography, and psycho-physical and emotional drivers factors. It has been proved that the police authorities and units cannot fully ensure transport safety in the European Union because the safety is formed by a complex of actions by the state and road users.

Background: The pathophysiologic mechanisms of early acute lung injury (ALI) differ according to the type of primary insult. It is important to differentiate between direct and indirect pathophysiologic pathways, and this may influence the approach to treatment strategies. NF-$\kappa$B decoy oligodeoxynucleotide (ODN) is a useful tool for the blockade of the expression of NF-$\kappa$B-dependent proinflammatory mediators and has been reported to be effective in indirect ALI. The purpose of this study was to investigate the effect of NF-$\kappa$B decoy ODN in the lipopolysaccharide (LPS)-induced direct ALI model. Methods: Five-week-old specific pathogen-free male BALB/c mice were used for the experiment. In the preliminary studies, tumor necrosis factor (TNF)-$\alpha$, interleukine (IL)-6 and NF-$\kappa$B activity peaked at 6 hours after LPS administration. Myeloperoxidase (MPO) activity and ALI score were highest at 36 and 48 hours, respectively. Therefore, it was decided to measure each parameter at the time of its highest level. The study mice were randomly divided into three experimental groups: (1) control group which was administered 50 ${\mu}L$ of saline and treated with intratracheal administration of 200 ${\mu}L$ DW containing only hemagglutinating virus of Japan (HVJ) vector (n=24); (2) LPS group in which LPS-induced ALI mice were treated with intratracheal administration of 200 ${\mu}L$ DW containing only HVJ vector (n=24); (3) LPS+ODN group in which LPS-induced ALI mice were treated with intratracheal administration of 200 ${\mu}L$ DW containing 160 ${\mu}g$ of NF-$\kappa$B decoy ODN and HVJ vector (n=24). Each group was subdivided into four experimental subgroups: (1) tissue subgroup for histopathological examination for ALI at 48 hours (n=6); (2) 6-hour bronchoalveolar lavage (BAL) subgroup for measurement of TNF-$\alpha$ and IL-6 in BAL fluid (BALF) (n=6); (3) 36-hour BAL subgroup for MPO activity assays in BALF (n=6); and (4) tissue homogenate subgroup for measurement of NF-$\kappa$B activity in lung tissue homogenates at 6 hours (n=6). Results: NF-$\kappa$B decoy ODN treatment significantly decreased NF-$\kappa$B activity in lung tissues. However, it failed to improve the parameters of LPS-induced direct ALI, including the concentrations of tumor necrosis factor-$\alpha$ and interleukin-6 in BALF, myeloperoxidase activity in BALF and histopathologic changes measured by the ALI score. Conclusion: NF-$\kappa$B decoy ODN, which has been proven to be effective in indirect models, had no effect in the direct ALI model.
This study explores the ideal corporate social responsibility(CSR) that fashion consumers expect from a fashion firm in the identification of dimensions and levels of consumer expectations as well as examines the impact of CSR expectations on customer-base brand equity. The data of 315 adults were collected through a nationwide online survey. In order to analyze the data, this study employed Confirmatory factor analysis (CFA), paired t-test, structural equation modeling(SEM), and descriptive analysis. This study first identified seven fashion CSR expectations (environmental, ethical, social, internal management, philanthropic, economic, and legal expectations). Internal management and environmental activities were highly expected from fashion firms; however, economic activity was low in expectations. Five models separately tested the relationship between CSR expectations and brand equity (trustworthiness, attachment, performance, social image, and value). Economic, environmental, internal management, social and ethical CSR expectations influenced customer-based brand equity; however, philanthropic and legal expectations did not influence any dimension of customer-based brand equity. This study provides a framework of ideal CSR from a consumer perspective and suggests that fashion marketers should focus on economic, environmental, internal management, social and ethical CSR activities to meet the expect Haitians of fashion consumers and build stronger brand equity.
The purpose of this empirical study is an index to usage of export assistance programs for korean small-medium exporters. Build around the index make an analysis of SMEs internal or exterior factors have an effect on export at present or in future export performance and the relative importance. Based on 128 surveys form korean SMEs experienced export assistance programs, 8 hypotheses, which are set up each factor, were verified through the practical analysis. The main result of hypothesis drawn by empirical study are as follows : The more SMEs use the programs, the more high export performance at present and in future. Export competitive factor reject at present export performance, but it will affect future export performance. A size of the firm in the characteristics of SEMs will affect export performance. Export rate of own brand will not affect performance. Another factors show adoption partly concerned hypothesis. Classified exterior factors of SMEs, a intensity of market competition shows adoption partly concerned hypothesis. Market growth rate will affect export performance at present and future strongly. Finally the usage of assistance programs will affect between a consumption goods and an industrial goods differently. From this study we found if we want to develop the export assistance programs that can actually in phases help the SEMs.
