We compared standard culture methods as well as conventional PCR and real-time PCR for the detection of Listeria monocytogenes (L. monocytogenes) in milk, cheese, fresh-cut vegetables, and raw beef that have different levels of background microflora. No statistical differences were observed in sensitivity between the two selective media in all foods. In total, real-time PCR assay exhibited statistically excellent detection sensitivity (p<0.05) and was less time consuming and laborious as compared with standard culture methods. Conventional culture methods showed poor performance in detecting L. monocytogenes in food with high levels of background microflora, generating numerous false negative results. While the detection of L. monocytogenes in fresh cut vegetable by culture methods was hindered only by L. innocua, various background microflora, such as L. innocua, L. welshimeri, L. grayi, and Enterococcus faecalis appeared on the two selective media as presumptive positive colonies in raw beef indicating the necessity of improvement of current selective media. It appears that real-time PCR is an effective and sensitive presumptive screening tool for L. monocytogenes in various types of foods, especially foods samples with high levels of background microflora, thus complementing standard culture methodologies.

As urbanization has evolved, a number of cities have been engaged in building creative power through branding. Cities contain much creative space and creative space within cities develops them. Cities are connected with space, which have a great influence each other, in particular, in cities of culture and art. Space contents in cities have various forms and types and work as important factors for branding of cities. In this high-touch generation, cities of culture and art have special meaning in that design of emotional generation, and cultural meaning of tangible and intangible assets in cities are their competitive power and sources of high added value. The cities of culture and art are oriented toward creative future globally and nationally. In cities of culture which seek for urban development by excavating artistic meaning and value through artistic and cultural development, their cultural meaning itself can become a brand, which effectively leads to building creative cities and marketing of urban brands. This study aims to analyse cases of cities developed through discovering or reactivating art and cultural meaning and value of urban space based on urban space contents. Then it analyses through what urban image, brands and marketing space contents were developed and suggests necessity of space contents development in small and middle sized cities. Therefore, based on the cases of art and cultural cities developed depending on space contents, it analyses and differentiate their various types and contents, aiming to show that any cities can be based on art and culture and creativity depending on creation, regeneration and development of space contents.

본 실험은 산마늘의 산초 증식과 인경 형성에 적합한 생물반응기 배양방식과 인경 형성시 배양방식에 따른 당 대사를 구명하고자 실시되었다. 다신초 증식에는 생물반응기에 망을 걸고 배지에 절편체를 접하게 배양한 RC와 MRC (13-15개)에서 가장 좋은 결과를 얻었다. 인경형성과 비대에는 간헐적으로 배지를 공급해준 E&FS에서 93.4％의 인경형성이 이루어졌고 크기에 있어서도 균일하였다. RC와 MRC에서 형성된 인경은 뿌리가 무성하였으며 인경의 크기도 균일하지 않았다. 배양방식별로 수확한 인경내 유리당 함량은 전반적으로 E&FS.에서 낮았던데 반해 전분 함량은 높았다. 배지내 sucrose, glucose와 fructose는 인경 비대 시기에 감사되었는데 이는 첨가한 sucrose가 가수분해 되기도 전에 glucose나 fructose와 함께 식물체로 바로 이용됨을 보여주는 것이었다.

Purpose: This study aimed to investigate the relationship between nursing work environment, patient safety culture, and patient safety nursing activities in hemodialysis units at primary care centers. Methods: In this cross-sectional descriptive study, 116 nurses working in hemodialysis units at 22 primary care centers were enrolled as participants. They were selected them by the convenience sampling method. Data were collected using structured questionnaires that included questions on general characteristics, nursing work environment, patient safety culture, and patient safety nursing activities. Results: The nursing work environment was relatively good; however, the patient safety culture and patient safety nursing activities were poor. A positive correlation was found between nursing work environment, patient safety culture, and patient safety nursing activities. Factors that affect patient safety culture were rated high in the order of nursing work environment and patient safety nursing activities, and factors affecting patient safety nursing activities were rated high in the order of patient safety culture and age. Conclusion: This study showed that the development of tailored patient safety training for nurses in hemodialysis units working in primary care and administrative support from those institutions are needed. In particular, strategies accounting for nurses' characteristics such as age are required to strengthen patient safety nursing activities.

Purpose: The purpose of this study examines the mediating effect of clan leadership in the relationship between hierarchy culture and organizational commitment. Most previous research focused on the relationship between organizational culture and organizational performance or organizational culture and job satisfaction. There are few empirical studies that focus on organizational commitment data because it is difficult to collect in many cases of export-driven small and medium sized enterprises. However, this research measures affective commitment, continuance commitment, and normative commitment differently than previous research, which is mostly focused on the hierarchy culture, clan leadership, and organizational commitment measurements. Research design, data, methodology: Conceptual research model is based on the studies of Cameron and Quinn (2011), and Gungor and Sahin (2018). The model is designed with three constructs such as hierarchy culture, organizational commitment, and clan leadership. The monitor culture and coordinator culture are as proxy for the hierarchy culture. The affective commitment, continuance commitment, and normative commitment are as proxy for the organizational commitment. And also the facilitator leadership and mentor leadership are as proxy for the clan leadership. Based on three hundred cases such as export-driven small and medium sized enterprises (SMEs), this study verify the hypothesis. Hypothesis was analyzed with the structural equation modeling. Results: In case of export-driven small and medium sized enterprises (SMEs), clan leadership acts as a mediator in the relationship between hierarchy culture and organizational commitment. In case of export-driven small and medium sized enterprises (SMEs) with high organizational commitment, clan leadership acts as a mediator in the relationship between hierarchy culture and organizational commitment. In case of export-driven small and medium sized enterprises (SMEs) with low organizational commitment, clan leadership did not act as a mediator in the relationship between hierarchy culture and organizational commitment. Conclusions: By controlling for the mediating effect of clan culture, this study have improved the academic contributions as well as policy and practical implications through empirical study of clan leadership that affect organizational commitment in the fields of hierarchy culture. In addition, this study means that the mediating effects on the variables of clan leadership were examined.

Purpose: This study was designed to assess the types of nursing organizational culture, and degree of self-leadership and burnout as perceived by perioperative nurses, and to identify correlations between these variables. Methods: Participants were 155 nurses from 3 tertiary hospitals in Seoul and data were analyzed using descriptive statistics, ANOVA, Scheffe, and Pearson correlation coefficient. Results: In the types of nursing organizational culture, the mean score for hierarchy-oriented culture was 3.57, and for self-leadership, 3.61 and for burnout, 2.87. In the relationship between the types of nursing organizational culture, self-leadership and burnout, relation-oriented culture (r=.24, p<.01), innovation-oriented culture (r=.23, p<.01) and task-oriented culture (r=.22, p<.01) had a slight positive correlation with self-leadership in that order. The innovation-oriented culture (r=-.29, p<.01) and relation-oriented culture (r=-.42, p<.01) among the types of nursing organizational culture showed a negative correlation with burnout while the hierarchy-oriented culture (r=.28, p<.01) showed a positive correlation with burnout. Self-leadership showed a negative correlation with burnout (r=-.42, p<.01). Conclusion: The results show that nurses in operating rooms have a high awareness of hierarchy-oriented culture that affects burnout in a negative way while having a low awareness of relation-oriented culture that has a positive influence on burnout.

Mycopasma contamination of tissue culture cells easily evades detection and, thus, represents a continous therat to cell biologists. In case where infected cell can not simply be replaced, attempts have to be made to eradicate mycoplacma from the tissue culture cells. A variety of anti-microbial agents have been shown to be toxic to mycoplasma strains ; however, cell associated mycoplasma are often protected from antibiotics at concentrations shown to be effective in vitro. Antibiotic concentrations high enough to be lethal to cell as sociated mycoplasmas frequently are also detrimentrations to the host cells, while moderately increased antibiotic levels tolerated by the host cells often lead to only temporary growth suppression and/or to the emergence of mycoplasma strains resistanct even to high concentrations of the antibiotis applied. Hare, a genetic approach for the elimination of mycoplasma from tissue culture cells that overcomes thens limitations is described. By expression of a selection marker conferring resistance to an otherwise toxic agent, Acholeplasma laidlawii infected BHK-21 cells used as the model system were enabled to temporarily tolerate antibiotic concentrations high enough to be lethal to cell associated mycopalsma while leaving the host cells unharmed. Upon successful mycoplasma eradicated, cultvation of the cured host cells in the absence of the selective agent yielded revertant cell clones that had regained susceptibillity to the toxic agent. Cressation of the selection marker expression was shown to result from the loss of the selection marker DNA, which is a consequence of the fact that the stable and permanent integration of foreign DNA in eucaryotic cell chrosomes is highly inefficient. Thus, the cells were cured from mycoplasma yet remained biochemically unaltered.

The utilization methods of algae biomass have been studied constantly in whole world. These are $\circled1$the wastewater treatment if waste stabilization pond and oxidation ditch etc. and $\circled2$the biosorption of heavy metals and recovery of strategic' precious metals and $\circled3$the single-celled protein production and the production of chemicals like coloring agent and $\circled4$the production of electric energy through methane gasification. The culture system also has been developed constantly in relation with such utilization method developments. In the result of experimental operation under continuous and cyclic irradiation of light, using high rate algae biomass culture pond(HRABCP), which had been made so as to be an association system with the various items which had been managed to have high efficiency for algae culture, the algae production of the 12 hours-irradiance pond was 41.48 Chlorophyll-a ${\mu}g/L$ only in spite of having the more chance of $CO_2$ synthesis to algae cell than the 24 hours-irradiance pond. This means that the energy supply required for dark-reaction of photosynthesis is very important like this. The difference of algae production between continuous and cyclc irradiation explains that the dark-reaction of photosynthesis acts on algae production as the biggest primary factor. The continuous irradiance on HRABCP made the good algae-production($1403.97{\;}{\mu}g$ Chlorophyll-a/mg) and the good oxygen-production(5.8 mg $O_2/L$) and the good solid-liquid seperation. especially, DO concentration through the oxygen-production was enough to fishes' survival.

발효된 버섯배지 및 부엽토 등으로부터 80여 종의 균주를 1차 분리하여 CMCase, amylase 및 protease활성이 높고 버섯질병균주에 대한 항균활성이 높으면서 표고버섯 및 팽이버섯의 생육에는 전혀 영향을 미치지 않는 HJ-57 항균미생물을 최종 분리균주로 선정하였다. 최종 선정한 HJ-57 항균미생물을 동정한 결과 Bacillus sp. HJ-57로 밝혀졌으며, 배양을 위한 배지의 초기 pH는 pH 7, 배양온도는 $35^{\circ}C$가 최적인 것으로 나타났다. Bacillus sp. HJ-57균주는 12 hr 배양하였을 때는 약간의 항균활성을 나타내었지만, 배양 36~48 hr 배양하였을 때는 비교적 높은 항균활성을 나타내었다. Bacillus sp. HJ-57 항균미생물은 팽이버섯 재배농가에서 사용하는 콘코프 함유배지상에서도 버섯질병균주인 세균 및 곰팡이에 대하여 매우 높은 항균활성을 나타내었다.
