The purpose of this research is to analyze the influence of job enrichment and empowerment on organizational commitment. In addition, the role of work motivation and job satisfaction in mediating the influence of job enrichment and employee empowerment on organizational commitment has also been examined in this study. The sample population consists of all the employees in the regional office of DJKN Bali and Nusa Tenggara, who hold executive positions and have served the office for ≥ 4 years. This study adopts the second-order Partial Least Square (PLS) model and the Smart PLS Version 3.0 program which is used as the analysis tool. The results revealed that: job enrichment has a significant influence on organizational commitment; employee empowerment has an insignificant influence on organizational commitment; work motivation and job satisfaction partially mediate the influence of job enrichment on organizational commitment; work motivation and job satisfaction fully mediate the influence of employee empowerment on organizational commitment. The findings can be used as organizational considerations in developing policies related to job enrichment and employee empowerment, which is expected to motivate and provide satisfaction for employees and improve their organizational commitment.

Purpose: This study is to identify the relationship among married nurses' social support, work-family conflict and work-family enrichment and to examine the influence of social support on work-family conflict and work-family enrichment. Methods: Data were collected from married nurses working at three hospitals with more than 100 beds in J Province and analyzed by descriptive statistics, t-test, ANOVA, Mann-Whitney U test, Kruskal-Wallis H test, Pearson's correlation analysis and hierarchical regression analysis using SPSS 21 program. Findings: In the correlation analysis only social support and work-family enrichment showed positive correlation. As a result of hierarchical multiple regression analysis, social support still acted as a significant influence factor on work-family conflict and work-family enrichment even in the state of considering the effect of control variables. Conclusion: In order to lower work-family conflict and to enhance work-family enrichment of married nurses, it is necessary to introduce and implement welfare policies for work-family reconciliation at the workplace level and at home level it is necessary to provide concrete measures so that married nurses can find the value of life as workers while house working and nurturing.

Identifying carbapenem-resistant Enterobacteriaceae (CRE) is necessary to prevent nosocomial CRE infection outbreaks. Here, a rapid identification method with reduced enrichment time was developed without compromising accuracy. A total of 49 rectal swabs requested for CRE screening at the Department of Diagnostic Medicine at Hospital B in Busan, Korea, were included in this study. Specimens were inoculated on MacConkey and CHROMID Carba media either directly or following enrichment for 3, 6, and 24 h in 100 μl trypticase soy broth containing an ertapenem disk. The enriched cultures were further inoculated on CHROMID Carba or MacConkey media containing an ertapenem disk. In total, 19 CRE and 5 carbapenem-intermediate Enterobacteriaceae isolates were obtained from the 49 swabs. Among the 19 CRE isolates, carbapenemase-producing Enterobacteriaceae constituted 13 strains. Moreover, of the 19 CRE isolates, 16 (81.25%) and 17 (88.24%) were identified from the direct cultures on MacConkey and CHROMID Carba media, respectively. After 3 h of enrichment, the proportions of the CRE identified in the media were: MacConkey medium, 16/19 (81.25%); CHROMID Carba medium, 17/19 (88.24%); and MacConkey medium containing an ertapenem disk, 17/19 (88.24%). The detection rates after 6 h of enrichment were the same for all three media (19/19 strains, 100%), whereas those after 24 h of enrichment were 21, 22, and 24 strains, respectively, but included false positives. These findings suggest that a 6-h enrichment before inoculation on the CHROMID Carba medium is optimal for the rapid and accurate detection of CRE in clinical samples.

The objective of this study was to examine the effect of phosphorus deficiency on nitrogen fixation and photosynthesis of nitrogen fixing soybean plant under $CO_2$ enrichment condition. The soybean plants(Glycine max [L.] Merr.) inoculated with Bradyrhizobium japonicum MN 110 were grown with P-stressed(0.05 mM-P) and control(1 mM-P) treatment under control$(400\;{\mu}l/L\;CO_2)$ and enrichment$(800\;{\mu}l/L\;CO_2)$ enviromental condition in the phytotron equipped with high density lamp$(1000\;{\mu}Em^{-2}S^{-1})$ and $28/22^{\circ}C$ temperature cycle for 35 days after transplanting(DAT). At 35 DAT, phosphorus deficiency decreased total dry mass by 64% in $CO_2$ enrichment condition, and 51% in control $CO_2$ condition. Total leaf area was reduced significantly by phosphorus deficiency in control and enriched $CO_2$ condition but specific leaf weight was increased by P deficiency. Phosphorus deficiency significantly reduced photosynthetic rate(carbon exchange rate) and internal $CO_2$ concentration in leaf in both $CO_2$ treatments, but the degree of stress was more severe under $CO_2$ enrichment condition than under control $CO_2$ environmental condition. In phosphorus sufficient plants, $CO_2$ enrichment increased nodule fresh weight and total nitrogenase activity(acetylene reduction) of nodule by 30% and 41% respectively, but specific nitrogenase activity of nodule and nodule fresh weight was not affected by $CO_2$ enrichment in phosphorus deficient plant at 35 DAT. Total nitrogen concentrations in stem, root and nodule tissue were significantly higher in phosphorus sufficient plant grown under $CO_2$ enrichment, but nitrogen concentration in leaf was reduced by 30% under $CO_2$ enrichment. These results indicate that increasing $CO_2$ concentration does not affect plant growth under phosphorus deficient condition and phosphorus stress might inhibit carbohydrate utilization in whole plant and that $CO_2$ enrichment could not increase nodule formation and functioning under phosphorus deficient conditions and phosphorus has more important roles in nodule growth and functioning under $CO_2$ enrichment environments than under ambient condition.

This study was conducted to investigate the effect of early $CO_2$ enrichment during seedling stage on long-term $CO_2$ enrichment after transplanting in the culture of pat-choi (Brassica campesris L), spinach (Spinacia oeracea L.), and leaf lettuce (Lactuca saliva L). During seedling stage, $CO_2$enrichment had significantly higher fresh and dry weight and leaf area of the top parts (above ground) of all three plant species than the control (no $CO_2$ enrichment). About 53%, 70% , and 40% increase in fresh weight of the top parts of pak-choi, spinach, and leaf lettuce were observed, respectively. Also, in seedling stage, dry weights of roots of spinach and leaf lettuce were significantly increased by early $CO_2$ enrichment. Relative fresh weight increment, compared with fresh weight of the control, in the top parts of roll three plants showed the highest values in 10 days after $CO_2$ enrichment treatment. In the long-term $CO_2$ enrichment experiment, early $CO_2$ enrichmented plants had 20% greater leaf area than the control in all three leafy vegetables. Fresh and dry weights of top parts of early $CO_2$-treated plants were also increased from 10 to 20%, as compared with the control plants. However, these increasement rates in the long-term $CO_2$ enrichment were lower than those seedling stage, which had 30-60% increment-rates. After transplanting, photosynthetic rate of each leafy vegetable in the control treatment slowly decreased, but those rates of early $CO_2$ enriched plants rapidly decreased.

The object of this study was to compare the performance of commercial enrichment media used for Shigella spp. A total of four enrichment media, Gram negative (GN) broth, Shigella broth (SB), selenite-F (SF) broth, and selenite cystine (SC) broth, were tested. When S. sonnei was inoculated into each enrichment broth at 10 cfu/mL of concentration, the highest growth was observed in Shigella broth. Morganella spp., which was not differentiated in selective agar of Shigella spp. thus can be counted as false positive, did not grow in Shigella broth in enrichment step. When S. sonnei was artificially inoculated into pork, it was mostly recovered through an enrichment process with GN broth and SF broth. However, in the case of beef, S. sonnei was mostly recovered with GN broth but largely failed with Shigella broth. Therefore, enrichment media for Shigella spp. should be selected by considering the food matrix in order to increase the chance of isolating it from foods.

The present investigation was undertaken to determine if CO2 enrichment promoted rooting and subsequent growth of Lagerstroemia indica L. cuttings. Cutting were taken from the one-year-old semihardwood twigs, and rooted in enclosed propagation frame with enriched CO2 levels (500-2000ppm) regulated by a gas monitor. The base of each cutting was dippid from 500 to 4000ppm naphthalenacetic acid. Roothing was determined after 3 months. CO2 enrichment during roothing increased the rooting percentage and number of roots per cutting, but nontreated cuttings rooted in low percentages producing one or two roots. The length of new shoots and dry weight of whole cuttings in CO2 enrichment were significantly greater than those of the atmospheric controls. The organic and inorganic compounds concentraion were measured as an indication of nutritional state in whole cuttings. As a result of CO2 enrichment, carbohydrate, protein and inorganic compounds(total nitrogen, P2O5, K2O, CaO, MgO) concentration were higher than controls.
