  • Purpose: The purpose of this study was to identify the relationship between organizational culture and workplace bullying of intensive care unit (ICU) nurses. Methods: A secondary analysis was conducted using three different data sets on workplace bullying of hospital nurses. This analysis focused on the relationship between organizational culture and workplace bullying of 240 ICU nurses. The original data were collected using self-reporting questionnaires and were analyzed using hierarchical multiple regression. Results: ICU nurses were aware of their organizational culture as being rank-oriented, relationship-oriented, innovation-oriented, and task-oriented in that order. The results showed that 15.0% of the ICU nurses reported being victims of workplace bullying, mostly work-related bullying. The perception of a relationshiporiented culture explained a variance of 29% in the workplace bullying of ICU nurses. Conclusion: The findings suggest that ICU nurses who are strongly aware of a relationship-oriented culture would experience less workplace bullying. Further research is needed to develop interventions that can foster a relationship-oriented culture in ICUs.

  • The potential antiviral effects of the culture filtrates (CF) from Serratia marcescens strain Gsm01 against yellow strain of Cucumber mosaic virus (CMV-Y) were investigated. The culture filtrate of S. marcescens strain Gsm01 applied on Chenopodium amaranticolor showed high inhibitory activity, likewise no necrosis appeared when applied on the tobacco plants 2 days before CMV-Y inoculation. When plants were challenge inoculated with CMV-Y for eighteen days, the disease incidence in plants with culture filtrate of S. marcescens Gsm01 did not exceed 59%, whereas 100% of control plants were severely infected. The results of double antibody sandwich-enzyme linked immunosorbent assay (DAS-ELISA), reverse transcriptase polymerase chain reaction (RT-PCR), dot blotting, and western blotting showed that culture filtrate treatment highly affected the accumulation of CMV-Y or its CP protein gene in the treated plant leaves. It was also observed that the culture filtrate had no RNase activity on genomic RNAs of CMV-Y, suggesting that culture filtrate may not contain ribosome inactivating proteins (RIPs) or proteins with RNase activity. These data shows that culture filtrate of S. marcescens strain Gsm01 seems to be a promising source of antiviral substance for the practical use.

  • Optimization of submerged culture conditions for the production of exo-biopolymer from Paecilomyces japonica ws studied. Maltose, yeast extract, and potassium phosphate were the most suitable sources of carbon, nitrogen, and inorganic salt, respectively, for both production of the exo-biopolymer and mycelial growth. The optimal culture conditions in a flask culture were pH 5.0, $25^{\circ}C$, and 150 rpm in a medium containing (as in g/l) 30 maltose, 6 yeast extruct, 2 polypeptone, $0.5{\;}K_3HPO_4,{\;}0.2{\;}KH_2PO_4,{\;}0.2{\;}MnSO_4{\cdot}5H_2O,{\;}0.2{\;}MgSO_4{\cdot}7H_2O$. Exo-biopolymer production and mycelial growth in the above suggested medium were significantly increased in a 2.5-1 jar fermentor, where the maximum biopolymer concentration was 8 g/l. The morphological changes of the mycelium in the submerged culture were observed within pH ranges from 4.0 to 9.0; i.e., growth of the filamentous form was optimal at culture pHs of 5.0 and 6.0, whereas pellet was formed at other pHs.

  • Cordyceps militaris specimens were continuously collected by Entomopathogenic Fungal Culture Collection (EFCC), Kangwon National University from different mountains, national parks and recreation parks of Korea from 1986 to 2002, mainly from late May to October of each year. Dry specimens of C. militaris along with their isolates have been preserved in EFCC. Fruiting of C. militaris was induced from single ascospore isolates as well as their combinations in brown rice medium. Fruiting experiments showed that combinations of single ascospore isolates produced fertile fruiting bodies, but single isolates could not produce any fruiting bodies. It was shown that two isolates of the opposite mating types were required to produce fertile stromata. However, combinations of the same mating type isolates produced no fruiting body, showing that C. militaris is a bipolar, heterothallic fungus.

  • Liquid nitrogen storage is the most effective way to preserve many fungi including what cannot be lyophilized. The use of polypropylene straws instead of cryotubes has many advantages in economy, safety, convenience, and space-saving. We, Korean Agricultural Culture Collection (KACC), established the fungal preservation methods in liquid nitrogen using polypropylene drinking straws and introduced the methods in detail.

  • In order to establish an axenic (bacteria-free) culture of Microcystis aeruginosa NIER 10039 isolated from a Korean reservoir, the culture was subjected to sequential treatment, including ultrasonication, washing, and addition of antibiotics. Three broad-spectrum antibiotics, namely, kanamycin, ampicillin, and imipenem, were applied separately in that order. Axenicity of the culture was confirmed by cultivation on bacterial media and observation under epifluorescence and scanning electron microscopes. We are the first to establish an axenic culture of a Microcystis strain isolated from Korean reservoirs and can be used in physiological and molecular studies to control toxic Microcystis blooms.

  • The main objective of this study was to examine the effects of national context and family-friendliness of organizational culture in the private sectors on employee self-reported job and family life satisfaction. The data came from 1,613 employees of IT and retail companies in Korea, U. K., and Sweden, whom were married(partnered) with children under 12. The major findings of this study were as follows: The Swedish workers had more family-friendly perceptions about their organizational culture and more satisfaction about their job and family life compared with workers in U. K. and Korea. The hierarchical multiple regression analyses revealed that perceptions of family-friendliness of organizational culture were positively related to employees' job and family life satisfaction. It was also found that perceived family-friendliness of organizational culture and national context significantly predicted employees' job-family life satisfaction. The implications of study results were discussed.

  • The purpose of this study is to investigate the relationship between organizational culture types and organizational effectiveness in the hospitals and to identify the cultural and organizational characteristics of the hospitals with high organizational effectiveness. Data were collected from May 12 to June 14. 1997 through questionnaire taken by 1.118 nurses working in 10 hospitals with more than 800 beds and from annual reports published by the hospitals. The instruments were used for collecting the data: Organizational Culture Questionnatire and Organizational Characteristics Questionnatire developed by the researcher. Mowday's Organizational Commitment Questionnaire. Taylor & Bovver's General Satisfaction Scale. The Results were as follows: 1. The meta culture of the hospital organizations was the conservative culture. 2. There were significant differences of the four organizational cultural types - affiliative culture. innovative culture. conservative culture. task culture among the hospitals(p=.00). 3. The hospital organizations were classified in to three cultural patterns. each of which had similar cultural composition. on the basis of the scores indicating the similarity and difference of the foul' organizational cultural types among the hospitals. The organization of each group represents conservative- dominant culture. innovative-dominant culture and competitive culture. 4. Nurses' organizational commitment and job satisfaction were significantly different among the cultural patterns(p=.00). In other words. the hospitals with innovative-dominant culture showed higher organizational commitment and job satisfaction than ones with conservative-dominant culture and competitive culture. And also. the growth rate of outpatients and inpatients were significantly different among the cultural patterns(p<.05). The hospitals with innovative -dominant culture showed higher growth rate of outpatients and inpatients than ones with conservative-dominant culture and competitive culture. 5. The hospitals with conservative-dominant culture and competitive culture showed higher level of centralization than ones with innovative -dominant culture(p=.00) And the hospitals with competitive and innovative-dominant culture showed higher level of communication than those with conservative-dominant culture(p=.00) Finally. the hospitals with innovative-dominant culture showed higher level of managerial strategy than those with conservative-dominant and competitive culture. among which the latter showed higher level of managerial strategy than the former(p=.00).
