The purpose of this study was to identify convergence factors related to DSMK, social support, and educational needs on the diabetes in rural elderly. The subjects were 115 elderly patients who were registered in diabetes control center, taking medication more than 6 months in U city. The survey period was from August 24 to October 31, 2016. The results showed that DSMK showed significant differences in gender, education level, duration of diabetes, experience of diabetes education, experience of family participation in diabetes education, and perceived health status(p<.05). The degree of social support was found to be significant differences in marital status, diabetes education experience, diabetes education needs, gender, duration of diabetes, and perception of diabetes self-management difficulty(p<.05). There were significant positive correlations between DSMK and social support, social support and educational needs(p<.05). Based on these results, we hope to develop a convergent self - management program based on the needs of the elderly patients.

In this study, the characteristics of support behavior according to the change of ground condition of the cast-in-place pile and the large Caisson foundation, which are increasingly used as foundations of large structures and bridges. the allowable bearing capacity calculated using the yield load analysis method was analyzed to calculate similar allowable bearing capacity for each method. In addition, the allowable bearing capacity calculated by the ultimate load analysis method was found to have a large difference in bearing capacity for each method. Through this point, it can be usefully used as an empirical formula for evaluating the settlement characteristics of piles in future design and construction. In addition, as a result of examining the ground force distribution during sedimentation of large caissons, the section of the weathered rock layer showed almost constant ground force distribution as ground forces decreased after yield occurred at the base corner. And in the bed rock layer section, the foundation's center was transformed into a ground force in the form of a convex downward due to an increase in the ground resistance of the central part. Using these results, the theory previously presented by Fang (1991) and Kőgler (1936) was proved.

In this paper, the empirical relations of skin friction and end bearing resistance with the results of site investigation in soft rock are proposed through the analysis of bi-directional pile load tests of rock socketed drilled shafts performed at large offshore bridge foundations and high-rise building projects (13 test piles in 4 projects). The site investigation and drilling for bi-directional pile load tests were performed at the centers of test piles, and f-w curves for skin friction and q-w curves for end bearing were plotted based on load-transfer measurements. From the above curves, the empirical relations of skin friction and end bearing resistance with the results of site investigation depending on the mobilized displacement are determined by multiple regression analysis and compared with previous studies. Since the f-w and q-w curves of rock-socketed piles in Korea show hardening behavior according to mobilized displacement, the developed empirical relations by the mobilized displacement are more reasonable than those of previous studies which could not consider the mobilized displacement and suggested the ultimate capacity with unconfined compressive strength only. Particularly, the developed equations correlated with unconfined compressive strength show the best correlations among the equations correlated with other parameters.

The purpose of this study was to explore the causal relationships between turnover intention and its influencing factors among married female nurses. The participants included 148 married nurses at 5 general hospitals in J city. Data were collected by using self-reported questionnaires and were analyzed by using SPSS and AMOS software. The overall fitness of the modified path model to the data was good ($x^2/df=0.002$, GFI = 1.00, AGFI = 1.00, RMSEA = 0.00, NFI = 1.00, CFI = 1.00, TLI = 1.09). Job stress, social support, work-family conflict, and burnout explained 32.0% of the variance in turnover intention of the participants. In particular, work-family conflict had a complete mediating effect between job stress and burnout. In addition, work-family conflict had partial mediating effects between social support and burnout as well as between social support and turnover intention. Social support had direct and indirect effects on work-family conflict, burnout, and turnover intention. In conclusion, strategies for decreasing married nurses' burnout and turnover intention should focus on reducing work-family conflict and increasing social support.

This study is based on the theory of salutogenesis, and investigates factors affecting the health status of radiologists who experience high stress and health problems in the rapidly changing medical environment. The study enrolled 379 radiologists working at hospitals in Daegu. A health structure model was established by applying the theory of salutogenesis. Sense of coherence had a direct effect on the health status of radiologists. Psychological stress, social support, and drinking were also influential factors, due to their mediating effect on the sense of coherence. Moreover, social support was also found to be lower when job stresses were higher. Hence, increased psychological stress resulted in lower levels of sense of coherence, social support and exercise. Taken together, results of this study indicate that effects on the sense of coherence have maximum influence on the health status of radiologists, and social support among general resistance resources is an important factor for enhancing sense of coherence. In addition to social support and health behaviors, researches involving various resources and the development of organizational strategies and health promotion intervention programs are required in future, to enable radiologists to cope with their stresses and improve health.

As the level of job-seeking stress increases among college students, increasing attention is being paid to the variables that would decrease its negative effects through brief intervention programs or counseling. As such, in the present study, we examined the effects of job-seeking stress on depression and psychological well-being, and whether resilience (internal variable) and social support (external variable) would moderate such effects. In other words, we tested whether the negative effects of job-seeking stress on depression and psychological well-being would be decreased by resilience and social support. A total of 264 fourth-year college students and unemployed 4-year college graduates, who were looking for jobs in private and public enterprises participated in this study. The results indicated that resilience moderated the relation between job-seeking stress and depression, while social support did not. In contrast, resilience did not moderate the relation between job-seeking stress and psychological well-being, whereas social support did. These results suggest that as resilience increases, the effect of job-seeking stress on depression decreases, whereas as social support increases, the effect of job-seeking stress on psychological well-being decreases.

The purpose of this study was to determine the self efficacy, body image and family support affect on postpartum depression in early postpartum mothers. The data was collected 306 mothers on the first week after delivery from one hospital located in B city. The instruments were a survey of general characteristics, obstetrical characteristics, the Edinburgh Postnatal Depression Scale(EPDS), self-efficacy, body image and family support. Data was analysed using descriptive statistics, Pearson correlation coefficients, and stepwise multiple regression. The results revealed that the average item score of the EPDS was 6.09. The significant predictors of postpartum depression were body image, emotional state in pregnancy, and family support. These variables had a 38.4% explainability. The results indicate that the postpartum mothers should be screened for postpartum depression early in the postpartum period and it's necessary to implement nursing intervention focused on to enhance the body image and family support, especially the weak emotional state mothers in pregnancy.

The helical pile has become popular with some constructional advantages because relatively compact equipment is needed for installing helical piles. However, field loading tests for estimating the bearing capacity of helical piles have drawbacks that the required dead load should be as much as the operation load, and reaction piles or anchors are required. In this paper, the bi-directional load test without necessity of reaction piles and loading frames was applied to the helical pile, and the load-settlement curves of the helical piles were measured. The bi-directional load test was performed in two separate stages with the aid of a special hydraulic cylinder whose diameter is equal to that of the pile shaft. In the first stage, the hydraulic cylinder is assembled immediately above the bottom helix plate, and the end bearing capacity of the helical pile is measured. In the second stage, the hydraulic cylinder is assembled above the top helix plate, and the skin friction of the helical pile is measured. The pile loading-test program was carried out for the two different helical piles with the shaft diameter of 89 mm and 114 mm, respectively. However, the configuration of helix plates is identical with three helix plates of 450-, 350-, 200- mm diameter. Results of the bi-directional load test were verified by the conventional static pile loading test. As a result, the bearing capacity estimated by the bi-directional load test is in good agreement with the result of the conventional pile loading test.

This paper aims to compare the effectiveness of the chest compression when a person pushes on the infant's chest by using two fingers with the support during infant cardiopulmonary resuscitation, with the effectiveness of it without the support, and to find which one is better. For the study, 50 college woman students were tested during the simulation and the result of the test has been analyzed by chi-square test, Fisher's exact test. In case of the chest compression by using the support, the depth of the chest compression comes to $3.73{\pm}0.33cm$. On the other hand, in case of the chest compression without the support, $2.50{\pm}0.59cm$. It is founded that the method of pushing on the chest by using the support is more effective than that without the support (p < 0.001). It is concluded that the way that a person pushes on the infant's chest by using two fingers with the support during infant cardiopulmonary resuscitation has turned out to be more effective and useful. It is thought that in the future, the further study for it should be conducted.
