This study identifies the moderating effects of cognition on the relationship between self-care confidence and self-care behavior in the diabetic elderly. The participants were 205 elderly subjects with diabetes, who visited a citizen health center located in D city, Korea. Data were collected from 20th April to 31st August 2015, and were analyzed by t-test and multiple regression. Our results reveal no significant differences between the depressive and non-depressive groups, when considering diabetes self-management confidence, knowledge, behavior and cognitive function. Cognitive function had a moderating effect in the relationship between self-care confidence and self-care behavior only in the depressed group. Our results indicate that it is therefore necessary to apply individual nursing intervention based on cognitive function and depression level, and to develop various programs for improving the cognitive function and depression amongst the diabetic elderly.

The purpose of this study was to investigate the relationship between appearance satisfaction and school adjustment of nursing students. The role of self-esteem and gender in the relationship between appearance satisfaction and school adjustment were also examined. A descriptive correlational design was adopted and the convenience sample consisted of 188 undergraduate nursing students in D city. It was found that appearance satisfaction affected directly and indirectly through self-esteem on school adjustment. The results indicated that self-esteem had partial mediation effects in the relationship between appearance satisfaction and school adjustment. Moderation effect of gender was found only in the relationship between appearance satisfaction and self-esteem. This meant that women were affected more than men according to the level of appearance satisfaction. The results suggested that the intervention program to support nursing students to accept themselves more positively and to enhance their self-esteem will be effective to help nursing students adjust themselves more to school life. It was also indicated in this study that specialized intervention programs are needed for women.

Repeated administration of psychostimulants such as cocaine leads to the development of behavioral sensitization. Extracellular signal-Regulated Kinase (ERK), an enzyme important for long-term neuronal plasticity, has been implicated in such effects of these drugs. Although the nucleus accumbens (NAcc) is the site mediating the expression of behavioral sensitization by drugs of abuse, the precise role of ERK activation in this site has not been determined. In this study we demonstrate that blockade of ERK phosphorylation in the NAcc by a single bilateral microinjections of PD98059 (0.5 or $2.0{\mu}g/side$), or U0126 (0.1 or $1.0{\mu}g/side$), into this site dose-dependently inhibited the expression of cocaine-induced behavioral sensitization when measured at day 7 following 6 consecutive daily cocaine injections (15 mg/kg, i.p.). Acute microinjection of either vehicle or PD98059 alone produced no different locomotor activity compared to saline control. Further, microinjection of PD98059 ($2.0{\mu}g/side$) in the NAcc specifically lowered cocaine-induced increase of ERK phosphorylation levels in this site, while unaffecting p-38 protein levels. These results indicate that ERK activation in the NAcc is necessary for the expression of cocaine-induced behavioral sensitization, and further suggest that repeated cocaine evokes neuronal plasticity involving ERK pathway in this site leading to long-lasting behavioral changes.

Recently a B cell surface molecule, CD40, has emerged as a receptor mediating a co-stimulatory signal for B cell proliferation and differentiation. To investigate the mechanism of synergy between interleukin-4 (IL-4) and CD40 ligation in B cell activation, we have examined the effect of CE40 cross-linking on the IL-4 receptor expression in human B cells using anti-CE40 antibody. We observed that IL-4 and anti-CD40 both induce IL-4 receptor gene expression with a rapid kinetics resulting in a noticeable accumulation of IL-4 receptor mRNA within 4 h. While IL-4 caused a dose-dependent induction of surface IL-4 receptor expression, the inclusion of anti-CD40 in the IL-4-treated culture, further up-regulated the IL-4-induced IL-4 receptor expression as analyzed by flow cytometry. Pretreatment of B cells with inhibitors of protein tyrosine kinase (PTK) resulted in a significant inhibition of both the IL-4- and anti-CD40-induced IL-4 receptor mRNA levels, while protein kinase C (PKC) inhibitors had no effects. These results suggest that IL-4 and CD40 ligation generate B cell signals, which via PTK-dependent pathways, lead to the synergistic induction of IL-4 receptor gene expression. The rapid induction of IL-4 receptor gene expression through the tyrosine kinase-mediated signal transduction by B cell activating stimuli, would provide cells capacity for an efficient response to IL-4 in the early phase of IL-4 action, and may in part constitute the molecular basis of the reported anti-CD40 co-stimulatory effect on the IL-4-induced response.

The present study conducted in two parts toward employees in government office and state-owned companies, and financial companies. First, main impacts were demonstrated in the links between superior communication ability (SCA) and outcome variables (self-efficacy, and learning goal orientation). Second, mediating effects of self-efficacy and LGO were investigated in the relation SCA-Innovative behavior. The data which applied in analysis was collected from 318 employees who work at government office and state-owned companies, and financial companies in Jeju island. The results were as follows. First, SCA were positively associated with self-efficacy and LGO. Second, self-efficacy and LGO were fully mediated both relationships between SCA and innovative behavior. Findings were as follows. SCA is an important factor on self-efficacy and LGO. Such the results have meaningful implications in the research area of communication. The importance of self-efficacy and LGO were demonstrated when considering the both variable in the relations SCA-innovative behavior.

This study begins with the importance of customer satisfaction in public sector, social welfare and job enthusiasm and how authentic leadership impacts the job engagement and customer orientation. To analyze and to verify the hypothesis, a Structural Equation Model was constructed, with the genuine leadership as an independent variable, the job engagement as a parameter, customer orientation as a dependent variable. Sample data was collected from 230 employees of social welfare organizations located in Yong-in city. Strong association between authentic leadership perception and costomer oreintation was identified from structural equation model, where job engagement plays significant intermediating role. In conclusion, positive perception toward leadership characteristic influence the job performance through desirable attitude formulation. Job engagement as a mediating variable strengthens the influence of autheneic leadership on the improvement in customer orientation which overcame the opposition, the exhaustion due to emotional labor and job burnout from those who are engaged in welfare facilities.

PURPOSE: This study aimed to propose an exercise technique that helps improve the skeletal muscle function while suppressing the symptoms of respiratory distress, by mediating squat exercises in whole-body vibration for patients with severe COPD, and comparing the post intervention pulmonary function and activity of quadriceps. METHODS: Totally, 21 patients with severe COPD were randomly assigned to two groups through clinical sampling: experimental group I included 11 patients (Squat exercise combined with whole-body vibration exercise), and experimental group II included 10 patients (Only squat exercise). Before intervention, we measured pulmonary function using a pulmonary function tester, muscle activity of quadriceps using surface EMG, and gait ability using the 6MWT. RESULTS: Comparison of intra-group changes in both experimental groups showed a significant increase in the activity of rectus femoris, vastus medialis, and vastus lateralis, and also in the 6MWT. Intra-group comparisons also revealed significant difference in the activity of rectus femoris, vastus medialis, and vastus lateralis (p < .05). CONCLUSION: Squat exercise combined with whole-body vibration significantly increased the activity of the quadriceps muscle, suggesting that this intervention helps maintain the function of skeletal muscles and prevent muscle atrophy. Therefore, studies to develop protocols using whole body vibration in clinical practice as an exercise method can safely be performed in severe COPD patients, as considered necessary.

Social enterprises are companies that provide jobs to the vulnerable and provide social services. However, sustainable management of social enterprises is very difficult in a rapidly changing market environment. Therefore, for the sustainable management of social enterprise, it is assumed that the duty efficiency of the members of the social enterprise is most important in the limited resource environment, and that the social entrepreneur can increase the efficiency of the work by giving delegation to the members. Therefore, this study investigates how social entrepreneurs influence on the job efficiency of members when giving psychological empowerment to members of social enterprise based on social entrepreneurship. When giving empowerment leadership to members, And it has a significant effect on job efficiency.
