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.

대기 $CO_2$ 상승시 인산공급이 대두식물체의 광합성 및 질소고정에 미치는 영향을 살펴보고저 Bradyrhizobium japonicum MN110을 접종한 대두 식물체를 인산결핍구(0.05 m-P) 및 대조구(1.0 mM-P)를 처리하여 정상 $CO_2(400\;{\mu}l/L)$와 상승 $CO_2(800\;{\mu}l/L)$의 조건인 phytotron에서 35일 동안 재배하였다. 인산결핍은 건물량을 정상 $CO_2$ 처리시 51%, 상승 $CO_2$ 처리시 64%를 감소시켰고 총 엽면적도 유의성있게 감소시켰으나 specific leaf weight는 증가시켰다. 광합성 속도 및 잎내부의 $CO_2$농도는 인산결집구에서 감소하였고 그 정도는 $CO_2$ 상승처리시 더욱 컸으며 질소고정능과 근류생체량도 인산결핍시 감소하였으나 잎의 질소농도는 인산대조구가 30% 감소하였다. 이러한 결과는 $CO_2$ 상승조건에서도 인산이 결핍될 경우 식물생육을 촉진시키지 못하며 인산은 정상 $CO_2$ 농도시 보다 $CO_2$ 상승조건에서 근류의 성장과 작용에 더욱 중요한 역할을 하는것으로 유추된다.

본 연구는 엽채류 육묘시 $CO_2$시용이 정식 후 $CO_2$의 장기 시용으로 인한 청경채, 시금치 및 상추의 생육에 미치는 영향을 조사하였다. 육묘시 $CO_2$시용은 청경채, 시금치 및 상추의 지상부 생체중과 건물중 및 엽면적에서 모두 무처리구에 비해 현저히 증가하였는데, 생체중의 경우 처리구에서 각각 50%, 60% 및 30%내외의 증가를 나타내었다 뿌리 건물중은 시금치 및 상추에서 무처리구에 비해 처리구에서 현저히 증가하였다. 무처리구에 대한 지상부 생체중의 상대증가율은 청경채, 시금치 및 상추에서 공히 $CO_2$시용 10일 전후에서 가장 높았다. 정식후 $CO_2$시용 효과를 육묘시 $CO_2$를 시용한 처리구와 시용하지 않은 대조구로 구분하여 비교한 결과, 엽면적은 청경채, 시금치 및 상추에서 모두 처리구가 대조구에 비해 20%내외의 증가를 보였다. 지상부 생체중과 건물중은 처리구에서 3작물 모두 10~20%범위의 증가효과를 보였는데, 이는 육묘기의 30-60%의 증가효과에 비해 크게 둔화된 것으로 나타났다. 잎의 광합성속도는 정식 후 대조구에서 완만하게 감소하는데 비해 CO2를 장기 시용한 처리구에서는 급격히 감소하는 경향을 보였다.

연구는 식품으로부터 Shigella spp.를 분리하기 위해서 현재 사용되고 있는 증균배지를 대상으로 증균성능을 비교하였다. GN broth, Shigella broth, SF broth, SC broth 총 4개의 증균배지를 비교하였다. S. sonnei에 대해 각 접종 수준에 대한 성장은 Shigella broth에서 $10^1$ cfu/mL 낮은 수준의 존재 시에도 성장이 확인되었다. 분리배지에서 거의 구분이 되지 않는 Morganella spp.에 대한 증균은 Shigella broth를 사용할 경우 성장이 저해되었다. 식품을 대상으로 한 S. sonnei의 증균성능은 돼지고기에서 GN broth와 SF broth가 높은 증균능력을 보였으며 소고기에서는 GN broth에서의 증균능력이 높게 나타났으나 Shigella broth에서 증균능력이 높지 않았다. 실험에 사용된 배지는 식품 종류에 따라 증균되는 특성이 상이하므로 식품에서 Shigella spp.를 분리하고자 할 경우 우선적으로 식품 특성을 고려하여 증균배지를 선택하는 것이 바람직할 것으로 생각되었다.

The purpose of this study was to investigate the influences of work-family conciliation strategies on work-family conflict and enrichment in dual-earner couples who live in Daegu with children. The subjects of this study were 176 dual-earner couples, who have under 16 youngest children and work over 15 hours each week. The research tool was questionnaires. For data analysis, factor analysis, Cronbach ${\alpha}$, paired t-test and multiple regression were performed. The main results of this study were as following. First, there were significant differences in management and planning skill strategy, work-family conflict and enrichment according to gender. Second, positive attitudes strategy toward multiple responsibilities, wives use, had an influence on work${\rightarrow}$family conflict in wives. Also, partner coping, management and planning skill, and positive attitudes strategy, wives use, and management and planning skill strategy, husbands use, had an influence on family${\rightarrow}$work conflict in wives. And management and planning skill and professional adjustment strategy, husbands use, had an influence on family${\rightarrow}$work conflict in husbands. work-family conciliation strategies had no influence on work${\rightarrow}$family conflict. Third, positive attitudes strategy toward multiple responsibilities, wives use, had an influence on work${\rightarrow}$family enrichment in wives. Also, partner coping strategy, wives use, and management and planning skill strategy, husbands use, had an influence on family${\rightarrow}$work enrichment in wives. And positive attitudes strategy toward multiple responsibilities, husbands use, had an influence on work${\rightarrow}$family enrichment in husbands. Also management and planning skill strategy, wives use, and partner coping, professional adjustment and management and planning skill strategy had an influence on family${\rightarrow}$work enrichment in husbands.

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.
