Purpose: A descriptive correlational study was designed to examine the relationship of trait anger and anger expression to blood pressure, cholesterol, and depression in middle-aged Korean men. In addition, this study investigated the mediating effect of social support in relation to anger and other variables. Methods: Two hundred and ninety nine men aged 40 to 64 years were recruited from a health center at K University Hospital located in Ansan City, Kyungki province, Korea. The instruments used were Spielberger's state trait anger expression inventory-the Korean version for trait anger and anger expression, Beck's depression inventory for depression, and a Personal resource questionnaire for perceived social support. Results: Men with high trait anger showed significantly higher systolic blood pressure(BP) and diastolic BP The level of cholesterol did not have a significant relationship with trait anger and anger expression. The severity of depression was significantly higher in men with high trait anger or more frequent uses of anger-in or anger-out. The perceived social support had a significant mediating effect in relation to trait anger and depression. Conclusions: Various nursing interventions for managing anger or improving social support need to be developed in a future study.

Objectives: The purpose of this study is to find out differences in oral health status, defined as their oral health and oral health quality of life among the elderly depending on their income and education levels. Methods: This study used 922 senior citizens over 65 from the data (2015) of the 6th National Health and Nutrition Survey (NHNS). The regression analysis was adopted to identify factors affecting their oral health status which has effect on their oral health quality of life. The statistical package SPSS 21.0 was employed. Frequency analysis, chi-squared analysis and regression analysis were used, and the significance level or Cronbach's alpha value was 0.05. Results: Depending on income levels, there were differences in their oral health status as to whether they use oral hygiene products, take dental examinations, join private health-insurances, and delay dental treatments or not. And educational levels also made significant differences in their oral health status as to whether they smoke, drink alcohol, how many times they brush teeth a day, whether they use oral hygiene products, take dental treatments, and join private health-insurances. Regression analysis on the relationship between their oral health status and the oral health quality of life showed that there were significant differences depending on whether they take dental treatments, delay dental medical treatments, smoke, take oral examinations, how many times they brush teeth a day, and whether they use oral hygiene products, or join private health-insurances. Conclusions: The study shows that a comprehensive plan is needed to raise attention on proper oral health-care and ultimately to improve the quality of life by considering the daily number of tooth brushing, oral hygiene product use, regular dental treatments, and other medical uses.

This paper deals with the various conceptual metaphors of 'mind' in Korean and English within the Cognitive Semantics. The purpose of this paper is to investigate the metaphorical expressions of the concept 'mind' represented andunderstood in various ways in Korean and English, to find out the linguistically-universal conceptual metaphors underlying the uses of the metaphoric expressions. In addition, this paper discusses the differences in linguistic realization of the concept 'mind' between Korean and English from the socio-cultural background. In the traditional view, metaphor was thought only as the linguistic matters and a deviance from literal or normal use. However, within the Cognitive Linguistic view such as Lakoff and Johnson(1980), metaphor has been considered as a means of understanding and conceptualizing world. According to them, metaphor is found in everyday life because it is not only as a matter of language but also as a nature of human conceptual system controlling cognition, thought and behavior. Conceptual metaphor is suggested as a device to understood abstract and less familiar things through concrete and more familiar things. Conceptual metaphors may be realized linguistically as well as non-linguistically, in the form of movies, arts or behavior. To define the concept 'mind' shared among the Koreans, conceptual metaphors used to represent 'maum(mind)'in Korean are examined. Then they are compared with the ones used to represent 'mind' in English. This is based on the idea that conceptual metaphors represented in linguistic expressions naturally reflect the speakers' concept and conceptualization is a universal irrespective of language. This paper exemplifies the Korean sentences as well as English sentences to utilize some conceptual metaphor such as Johnson(1987)'s THE MIND IS THE BODY and shows many other conceptual metaphors used in Korean and English to represent the same concept 'mind'. What are some metaphors shared by two languages and what is specific to one of them will be shown, too. This paper also suggests that the different conceptualization or lexicalization is partly due to the effect of the oriental cultural background that is more interested in the mental world than the physical world.

The high-density polyurethane method uses the instantaneous expansion pressure of injected material to stabilize soft ground, allowing reinforcement, restoration, and construction to be carried out in suboptimal ground conditions. Under normal and, even poor conditions, the method is easily applied because the working time is very short. The method is environmentally friendly and results have excellent durability. The purpose of this study was to verify the physical and mechanical properties of high-density polyurethane in the ground. Initial testing of strength, direct shear, and soil environment stability was followed by testing for permeability in order to address environmental concerns. The results of the experiments showed that the internal friction angle was about twice as high and the adhesion was about 2.5 to 3.5 times higher than for dense and hard clay, and that the permeability factor was significantly lower compared with the existing grouting method, within the range of 1.0 × 10-5.
