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.

During the past two decades or so, science (or scientific or scientific & technological) culture has become one of the main themes not only of policy makers but also of science educators. Although, the idea of science culture has been taken as a desirable goal, there is little agreement about what it means and how to measure it. Particularly in Korea, there has been a rapid growth of science culture projects and programs, either by governmental or non-governmental, but with little systemic monitoring and evaluation for its practice. The purpose of this study is, thus, to explore a model of measuring science culture and develop a comprehensive indicator system for it. We reviewed many literatures on definitions of science culture and the surveys for related terms, particularly, of recent national and international surveys (e.g. US Science and Engineering Indicators, Eurobarometer, Japanese Science and Technology Indicators). Based on this review, a model for science culture is proposed and then used to define the Science Culture Indicators (SCI). This model encompasses two dimensions(i.e. individual and social), which are further divided into two aspects (i.e. potential and practice). Each dimension is expected to represent citizen literacy of and national infrastructure of science culture respectively. Each category in this $2{\times}2$ matrix is further divided into several sub-categories. The discussion concerning how the model and the indicators can be used to check the states of science culture at social as well as individual levels will be given with some concrete examples, such as indicators particularly related to science education.

Three-dimensional (3D) culture system is useful technique for study of in vivo environment and it was used various experiments. This study was investigated to establish of embryo co-culture system and changes of PAs activity in 3D cultured endometrial cells of pigs. In results, growth of stromal cells into gel matrix were detected only with endometrial and myometrial cells. The most rapid growth of stromal cells were confirmed in $2.5{\times}10^5cells/ml$ and gel matrix containing 15% FBS. Expression of urokinase-PA (uPA) after treatment of hCG (0.5, 1.0, 1.5 and 2.0 IU/ml) were higher than without hCG, but, there are not significant difference among the treatment. On the other hand, expression of uPA after treatment of $IL-1{\beta}$ (0.1, 1, 10 and 100 ng/ml) were higher than without $IL-1{\beta}$, but, there are not significant difference. Expression of uPA after treatment of estrogen (0.2, 2, 20 and 200 ng/ml) were not difference, but PA activity was significantly decreased (p<0.05). Blastocyst was producing in PZM-3 medium containing FBS and endometrial cells were grown in PZM-3 medium. When embryos development with cultured endometrial cells, cleavage rates were not significant difference and blastocyst were not produced in co-culture with stromal cells and 3D culture system. 3D culture system had similar activity to in vivo tissue and these features are very useful for study of in vivo physiology. Nevertheless 3D culture system was not proper in embryo co-culture system. Therefore, we suggest that 3D culture system with embryo co-culture need continuous research.

Scopolia parviflora Nakai, a rare and endangered species, is the sole plant producing tropane alkaloids (TA) among the Korean native species. In order to enhance TA productivity the SP72 root line was selected by screening 100 of root line, and the optimal culture media for root growth and TA production were investigated with the SP72 roots. Based on the several media, SH and 2B5 medium were determined as growth medium and White and NN medium as production medium. Among the four combinations of two-stage culture, 2BN (2B5 as growth medium plus NN as production medium) showed more enhanced root growth and TA production as compared with production media of White and NN medium and growth media of SH and 2B5 medium, respectively. However, bubble column bioreactor (BCB) cultures applying two-stage culture did not reveal the effective results despite of the each successful operation of two-stage culture in conical flasks and BCB cultures.

Lichen is a symbiotic mutualism of mycobiont and photobiont that harbors diverse organisms including endolichenic fungi (ELF). Despite the taxonomic and ecological significance of ELF, no comparative investigation of an ELF community involving isolation of a pure culture and high-throughput sequencing has been conducted. Thus, we analyzed the ELF community in Parmotrema tinctorum by culture and metabarcoding. Alpha diversity of the ELF community was notably greater in metabarcoding than in culture-based analysis. Taxonomic proportions of the ELF community estimated by metabarcoding and by culture analyses showed remarkable differences: Sordariomycetes was the most dominant fungal class in culture-based analysis, while Dothideomycetes was the most abundant in metabarcoding analysis. Thirty-seven operational taxonomic units (OTUs) were commonly observed by culture-and metabarcoding-based analyses but relative abundances differed: most of common OTUs were underrepresented in metabarcoding. The ELF community differed in lichen segments and thalli in metabarcoding analysis. Dissimilarity of ELF community intra lichen thallus increased with thallus segment distance; inter-thallus ELF community dissimilarity was significantly greater than intra-thallus ELF community dissimilarity. Finally, we tested how many fungal sequence reads would be needed to ELF diversity with relationship assays between numbers of lichen segments and saturation patterns of OTU richness and sample coverage. At least 6000 sequence reads per lichen thallus were sufficient for prediction of overall ELF community diversity and 50,000 reads per thallus were enough to observe rare taxa of ELF.

The purpose of this study is to analyze the characteristics of hospital organization structure, organization culture, organization conflict and the interrelation of influential factor in organization conflict. The data for this study were collected through a self-administered survey with a structured delivered to 755 subjects including several nursing staff members, administration staff members and medical technicians at six hospitals. The structural equation model was used to examine the relation of organization structure, organization culture and organization conflict. The results of the analysis in this study were as follows. First, organization structure had a positive influence on organization conflict, especially in terms of complexity and centralization. But, formalization had a negative influence on organization conflict. Second, organization culture had a positive influence on organization conflict, especially in terms of group culture, developmental culture, and hierarchical culture. But, group culture had a negative influence on organization conflict. Third, organization structure had positive influences, especially on organization culture complexity, centralization, and formalization. But, centralization had negative influences too.

Purpose : The purpose of this study was to investigate the influence of organizational culture on job satisfaction of fire officials. Method : The subjects of this study were 251 fire officials in Gongju and Choengju province and Daejeon City. Data were collected using self-administering questionnaire from February 20 to March 20 in 2006. Collected data were analyzed using SPSS 14.0 program. Real number, percentage, mean and standard deviation were calculated, and t-test, ANOVA, Pearson correlation coefficient, multiple regression were analyzed. Result : The results of this study were as follows : 1. The job satisfaction was found to be significant positive correlations with full organizational culture(r = .595, p = .000). 2. The job satisfaction was found to be in significant positive with rational goal culture, open system culture and human relation culture. 3. How organizational culture affects the job satisfactions was as follows; 25.2% of core values of manpower, 6.3% of rational goal culture, and 4.9% of job initiative. Conclusion : Enhancing the job satisfaction of fire officials would improve personalized factors and changes rational goal culture.
