As a considerable, experimental approach, an Auto-carriage type of $CO_2$ welding machine and a MIG(Metal Inert Gas) welding robot under inert gas atmosphere were utilized in order to realize Al 5083 welding applied to hull and relevant components of green Al leisure ships. This study aims at investigating the effect of welding conditions(current, voltage, welding speed, etc) on thermal deformation that occurs as welding operation and tensile characteristics after welding, by using Al 5083, non-ferrous material, applied to manufacturing of co-environmental Al leisure ships. With respect to welding condition to minimize the thermal deformation, 150A and 16V at the wire-feed rate of 6mm/sec were acquired in the process of welding Al 5083 through an auto carriage type of $CO_2$ welding feeder. As to tensile characteristics of Al 5083 welding through a MIG welding robot, most of tensile specimens showed the fracture behavior on HAZ(Heat Affected Zone) located at the area joined with weld metal, except for some cases. Especially, for the case of the Al specimen with 5mm thickness, 284.62MPa of tensile strength and 11.41% of elongation were obtained as an actual allowable tensile stress-strain value. Mostly, after acquiring the optimum welding condition, the relevant welding data and technical requirements might be provided for actual welding operation site and welding procedure specification(WPS).

Purpose: This study was performed in order to identify the relationships among self-care behavior, health conservation, and cardiovascular risk factors and to examine the influence of self-care behavior and health conservation on cardiovascular risk factors among Korean elders with diabetes mellitus. Methods: The participants were 105 elders with diabetes mellitus using senior welfare centers and elderly leisure houses in Daegu. Data were collected through interviews during the period from April to May in 2014. Self-care behavior was measured with Kim's (1997) Self-care Behavior Scale, health conservation with Sung's (2005) Health Conservation Scale, and cardiovascular risk factors with the Arizona Heart Institute Cardiovascular Risk Factor Questionnaire. Collected data were analyzed through one-way ANOVA, independent t-test, Pearson's correlation, and stepwise multiple regression using the SPSS/WIN 19.0 program. Results: A negative correlation was found between self-care behavior and cardiovascular risk factors, and between health conservation and cardiovascular risk factors. Self-care behavior explained 6% and health conservation did 49% of variance in elderly diabetes mellitus patients' cardiovascular risk. Conclusion: The results indicate that, in order to reduce cardiovascular risk factors among Korean elders with diabetes mellitus, we need nursing interventions for increasing health conservation and self-care behavior.

This study was designed to investigate body image, objective and subjective measurements of body size and shape, eating behavior, and weight control practices in 650 Korean adolescent girls; 500 of the subjects were 14 years old and enrolled in middle schools, while the remaining 150 were 17 years old and enrolled in high schools. Subjects responded anonymously to a self-administered questionnaire. The results showed that average height and weight of the subjects were 157cm and 49.5kg, respectively, while subjects ideal heights and weights averaged 164cm and 48kg, respectively. The ideal adult body heights and weights proposed by the subjects averaged 172cm and 55kg respectively. Over 50% of the subjects were dissatisfied with their body image; the degree of dissatisfaction with body image was higher in those who believed themselves to be fat. Most of the subjects wanted to lose weight and had tried to lose weight. Self-reported weight control practice methods included reducing food intake (31.9%), skipping meals (29.6%), exercise (25.8%), using slimming machines (6.9%), and using diet pills (5.1%). The heavier the subjects weight was, the greater the difference between the subjective and objective evaluations of body size. The body image scores of subjects who perceived themselves as fat were significantly lower than those of subjects who perceived themselves as normal or underweight. The difference between subjective and objective evaluations of body size, and the degree of obesity, were significantly higher in those subjects who had experience of weight control than those who had no experience of weight control. These results suggest that nutrition and health education programs for adolescent girls should be researched and implemented in order to establish a more realistic body image, positive habits in weight control, and healthful eating habits.

Objectives: This study aimed to understand the effect of factors, possibilities, and desires on oral examination experience behavior of the elderly using raw data from the 2017 Community Health Survey. Methods: Hierarchical logistic regression analysis, an analysis method that controls the input order of a series of independent variables, was performed for 67,835 senior citizens aged 65 and older. Results: In terms of predisposing factors-in women, the higher the level of education, the higher the oral examination practice rate, and the lower the oral examination practice rate in divorce and bereavement among those aged 75 years or older. Regarding enabling factors, the lower the income rating, the higher the oral examination experience rate in religious and social participants as well as, leisure and charity participants, and the lower the oral examination experience rate in the natural environment. Regarding the need factors, the oral examination practice rate was high when the subjective oral health level was recognized as good. Conclusions: As a result, Anderson's model confirmed that various factors affect oral examination experience behavior, and institutional support for policy consensus is needed to promote oral examination experience behavior in older people in various directions.
