In order for a strategy established by a company to be implemented efficiently, it must be supported by an appropriate organizational culture. This means that if a firm has an organizational culture suitable for strategy implementation, performance can be enhanced. This study divides competitive strategy into cost leadership strategy and product differentiation strategy, and organizational culture into hierarchical/rational culture and consensual/development culture. Based on 122 questionnaires collected through KOSPI listed manufacturing companies, the results of the empirical analysis on the effect of suitability between competitive strategy and organizational culture on performance by balanced scorecard perspective are summarized as follows. First, it shows that the cost leadership strategy and the hierarchical/rational culture are more fit. Specifically, The high suitability between the cost leadership strategy and the hierarchical/rational culture has a positive effect on the performance of the balanced scorecard perspective(excluding performance by learning and growth perspective). Second, The high suitability between the product differentiation strategy and the consensual/development culture has a positive effect on the performance of the balanced scorecard perspective. The results of this study suggest that it is important to form a corporate culture that can lead to changes in the beliefs and behaviors of organizational members in accordance with the competitive strategy in order to successfully implement the strategies established by the company.

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.

A suitable bioreactor culture system for shoot proliferation and bulblet formation of Allium victorialis var. platyphyllum Makino was established. Uptake of soluble carbohydrates in different bioreactor culture systems was also analyzed during the entire culture period. Optimal conditions for multiple shoot formation were determined in raft culture (RC) and modified raft culture system (MRC) (13-15 per explant) in which the explants were placed on a net contacting liquid medium. For bulblet formation and enlargement, 93.4％ of shoot clumps formed bulblets at the basal part. Furthermore, they were uniform in size when cultured with ebb & flood system (E&FS). Bulblets harvested from RC and MRC showed vigorous rooting, however, their growth was not uniform. Whereas soluble carbohydrate contents in the bulblets cultured in E&FS were low, starch content was high. Sucrose, glucose and fructose concentrations in the medium of E&FS culture system decreased as bulblet formation and enlargement proceeded, suggesting that external sucrose is taken up to by the cells before it is hydrolyzed.

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.

Approximately 80 species of bacteria were isolated from the fermented mushroom first and the HJ-57 antibacterial micro-organism was selected to the final isolation bacteria. It has a high degree of CMCase, amylase, and protease activity as well as high antibacterial activity against mushroom pathogenic bacteria without affecting the growth and development of Flammulina velutipes and Lentinus edodes mushrooms. The finally selected HJ-57 antibacterial micro-organism was identified as Bacillus sp. HJ-57. The initial pH for culture was pH7 and its optimum culture temperature was $35^{\circ}C$. The antibacterial material produced by Bacillus sp. HJ-57 showed a little antibacterial activity even in the 12 hr of culture, but showed the highest antibacterial activity in the 36~48 hr of culture. The HJ-57 antibacterial micro-organism also showed a high antibacterial activity against mushroom pathogenic bacteria and molds in the corn cob contained culture medium is used in Flammulina velutipes cultivators.
