When negative electron in x-ray tube is accelerated in to a high speed and then the currency of the electron is blocked by the target, x-ray happens by the conversion of the energy. The real area where the fast accelerated electron collides to a target area is called actual focal spot. When the string focused size is observed at the central ray side, where the direction x-ray comes out, the size seems to be reduced. This focus is called effective focal spot. According to radiation angle of x-rays tube, the degree of the negative pole side presents higher value than inclination, the amount of exposed radiation that patient receives differs by the angle of positive pole, which means effective focal spot is the variable. This paper presents the correlation between size of effective focal spot and amount of exposed radiation to the patient by it, and effective research for homogenized dose dispersion by the size of effective focal spot. In conclusion, following the focal size, effective range which was -8cm ~ 0 cm on average, was found and average dose rate was 0.019 R/min. Through this range, for patients with small radiation exposure, image with good density and resolution in aspect of diagnosing will be able to be obtained.

The purpose of this study is to examine the relationship between job-seeking stress and somatization symptoms and to explore the mediating effects of maladaptive self-focused and emotional dysregulation in college students. The SPSS 21.0 and AMOS 21.0 were performed to analyze the path relationship between variables. First, maladaptive self-focused mediated the relationship between job-seeking stress and somatization symptoms. Emotional dysregulation mediated the relationship between job-seeking stress and somatization symptoms. Second, maladaptive self-focused and emotional dysregulation partial dual mediated the relationship between job-seeking stress and somatization symptoms. It suggests that college students with job-seeking stress tend to be maladaptive self-focused, therefore they have difficulty in emotion regulation and eventually expose somatization symptoms.

In this study, the differential effects of exposure-type digital signage advertisement and interactive digital signage advertisement were examined through the moderating variables of regulatory focus and self-construal. As a result of the study, in the case of individuals with promotion focus and independent self-construal, interactive digital signage advertisements had a more positive effect than exposure-type digital signage advertisements. However, in the case of prevention focus and interdependent self-construal, there was no difference in effect between digital signage advertisement types. Therefore, we can help to establish a customized strategy according to individual characteristics using digital signage.

Modularity has merits in modifiability of product structure management and product arrangement. This feature helps consumer to expand the selection of products and to get customized products. Also consumers are drive satisfaction and reduce a post-purchase dissonance from role in a 'prosumer'. But expanding product's alternative would cause the overload confusion by rising complexity of information handling. Purpose of the study is to verify how interaction about option size and personal disposition are effected consumer's overload confusion. For this purpose we deducted 3 personal dispositions 'Regulatory focus', 'Product familiarity', 'Self-efficacy' that presented lead to potential effect of personal information handling by previous research. By statistical inquiry prevent focus group had perceived more overload confusion than promotion focus group in an expanding option size circumstances. And low Product familiarity and Self-efficacy group had perceived more overload confusion than high Product familiarity and Self-efficacy group in a expanding option size circumstances.

People's interest in how to lead a happy life when they get older is increasing because of the extension of life span due to thedevelopment of medical technology. Factors that can affect happiness or the strength of the influence of those factors may vary according to age. Previous studies, have found that individuals with promotion focus are more likely to experience happiness than those with prevention focus. However, whether this effect of regulatory focus on happiness is consistent regardless of age has not been sufficiently investigated. Therefore, 1,250 Korean adults from each age group and residence were randomly selected as thesample, and the moderating effect of age on the relationship between regulatory focus and subjective well-being was examined. The results indicated that promotion focus and age have a significant interaction effect on subjective well-being, while the interaction effect of prevention focus and age was not significant. More concretely, the positive effects of promotion focus on life satisfaction and affective balance grew stronger with increasing age. This finding implies that it is especially important for old adults to use promotion focus by actively setting challenging goals and motivating themselves to gain a sense of accomplishment to experience subjective well-being. In addition, social support is proposed as being especially important to activate their promotion focus.

This study is a study on the regulatory focus and entrepreneurship that affect entrepreneurial motivation under uncertainty. In the empirical analysis results between the prevention focus, risk taking, and economic entrepreneurial motive, which were not observed in previous studies in Korea, this study tried to supplementally verify the previous studies by focusing on the limitations of the sample suggested as limitations. In particular, under a special external environment where uncertainty is deepening due to COVID-19 and the economic situation is being severely hit, we regressively analyze regulatory focus and risk taking, which are innate personal characteristics that can affect entrepreneurial motives. The mediating effect of risk taking was demonstrated. As a result of the empirical results, it was found that the prevention focus, risk taking, and economic entrepreneurial motivation had a significant effect, and it was shown that risk taking had a mediating effect between the prevention focus and the economic entrepreneurial motivation. This result is meaningful as a result not observed in previous studies, and it is judged that the control focus, which is an individual characteristic with a large innate tendency, interacts with the risk taking of the acquired tendency to influence the motivation to start a business. The results of this study can be of practical help by understanding and concentrating on regulatory focus and risk taking when conducting entrepreneurship or entrepreneurship education programs to entrepreneurs who dream of or want to start a business amid the growing uncertainty of the external environment. On the other hand, it is necessary to confirm whether these results, which are different from previous studies, are the effect of sample diversity or the external environment such as Corona 19, and re-verification through additional research is needed in the future.
