  • Panax ginseng root has been widely used as an important drug for thousands years in China, Korea and Japan. The main effective components of ginseng have been believed to be saponins. However, ginseng cultivation is very difficult and needs many years for growth. It has already been shown that Panax ginseng callus produces a considerable amount of the same kinds of saponins as in intact plants. Various culture conditions were examined for increased production of ginseng saponins by cell culture. The saponin contents and the growth rates in two cell lines of ginseng callus were compared in static and suspension cultures, rotary and reciprocal shaking cultures. It was shown that the growth rate in rotary shaking cultures of D5-B2K-B2K callus was the highest and ginseng saponin production was most effective in reciprocal cultures of D5-B2K-B2K callus. The saponin content per fresh weight of the culture was 1.03 times higher than that of the fresh ginseng root.

  • Living culture, which is a pattern of peoples' everyday living, is influenced by the socio-economic conditions as well as ideology of the society. South and North Korean societies have been segregated during the past 50 years with different socio-economic conditions and idelogies, resultsing different living cultures, even though those two societies share the same traditional culture. This project was developed to identify the differences in living cultures between South and North Korean societies, and to make suggestions for their successful integration. The second part of the project was concentrated on finding out the current living culture of North Korean families. Based on indepth interview with ten people who escaped from North Korea after 1990, empirical survey with 158 subjects was conducted. The subjects with various demographic backgrounds were asked about lifestyles concerning family living, child rearing, consumption, time management that they experienced when they were in North Korea. This study revealed differences in many aspects of living cultures of South and North Korea, and relationships were suggested in four lifestyles. This study was intended to provide ground for more information to the following study that will explore the cue of integration between South and North Korean societies in living culture.

  • In the present study, we assayed a number of compounds isolated from Panax ginseng C. A. Meyer (Araliaceae) for an ability to protect rat cortical cell cultures from the deleterious effects of the neurotoxicant, glutamate. We found that ginsenosides Rbl and Rg3 significantly attenuated glutamate-induced neurotoxicity. Brief exposure of cultures to excess glutamate caused extensive neuronal death. Glutamate-induced neuronal cell damage was significantly reduced by pretreatment with Rbl and Rgl. Ginsenosides Rbl and Rg3 inhibited the overproduction of nitric oxide which routinely follows glutamate neurotoxicity and preserved the level of superoxide dismutase in glutamate-treated cells. Furthermore, in cultures treated with glutamate, these ginsenosides inhibited the formation of malondialdehyde, a compound produced during lipid peroxidation, and diminished the influx of calcium. These results show that ginsenosides Rbl and Rg1 exerted significant neuroprotective effects on cultured cortical cells. As such, these compounds may be efficacious in protecting neurons from oxidative damage produced by exposure to excess glutamate.

  • The purpose of this study was to the impact of organizational culture on the organizational effectiveness in hospitals were empirically analysed. Data were collected by 151 social workers including general hospitals with one social worker at least and single-department hospital with two social workers or more, were identified nationwide through the registry of Korean Association of Medical Social Workers and Korean Association of Hospitals. The results of this study were summarized as follows; First, most social workers report that characteristic of culture in their hospitals are group culture the first, hierarchial culture the second, rational culture the third, and developmental culture finally in order of social worker's recognition. Second, according to the types of organizational culture, there were significantly different levels of organizational effectiveness. Social worker's perceived group cultures in hospital showed higher job satisfaction, organizational commitment than other culture patterns. And also, social worker's perceived developmental cultures in hospital showed higher organizational commitment quality of social service than other culture patterns. Third, multiple regression analysis was conducted to find the relationship of organizational culture and organizational effectiveness. As a result, developmental culture showed a strong relationship with job satisfaction, organizational commitment and quality of social services Finally, as for the cultural affects on the organizational effectiveness depended on intensive attention to developmental culture in hospital Consolidating the attribute of developmental culture in hospital is also proposed to improve the organizational cultures.

  • Bioleaching studies of metals from a spent catalyst were conducted using both adapted and unadapted bacterial cultures. The bacterium used in this experiment was Acidithiobacillus ferrooxidans. A comparison of the kinetics of leaching was made between the two cultures by varying the leaching parameters, including the pulp density, particle size and temperature. Both cultures showed similar effects with respect to the above parameters, but the leaching rates of all metals were higher with the adapted compared to the unadapted bacterial cultures. The leaching reactions were continued for 240 h in the case of the unadapted bacterial culture, but only for 40 h in the case of the adapted bacterial culture. The leaching reactions followed first order kinetics. In addition, the kinetics of leaching was concluded to be a diffusion control model; therefore, the product layers were impervious.

  • Medicinal plants are high-value natural resources that have been used as precautionary drugs by many people globally. The increasing global demand for bioactive compounds from medicinal plants has led to the overexploitation of many valuable species. One widely used approach to overcome this problem is the use of adventitious root cultures as a propagation strategy. This review examines the scientific research published globally on the application of adventitious root cultures for many medicinal plants. Adventitious roots generated under aseptic environments in suitable phytohormone-augmented medium exhibit high growth rates and production of important secondary metabolites. Parameters such as medium properties and composition, growth hormone type, and elicitation strategies for in vitro grown adventitious roots of medicinal plants, are the main topics discussed in this review. We also examine current developments in bioreactor system cultivation for plant bioactive compounds using adventitious root cultures, a technology with possible commercial applications, via several studies on adventitious root culture of medicinal plants in which bioreactor systems play a role. In conclusion, the development of adventitious root cultures for medicinal plants is highly useful because of their capability for vegetative propagation and germplasm preservation.

  • Three Diels-Alder type adducts, guangsangon E (1), chalcomoracin (2) and sorocein I (3) were isolated from hairy root cultures of Morus macroura. The structures of the isolated compounds (1-3) were determined by spectroscopic method (NMR and MS), and spectral comparison to literature. Cytotoxic activities of the isolated compounds (1 - 3) were investigated against P-388 murine leukemia cell line. Guangsangon E (1) showed the most potent cytotoxicity against P-388 murine leukemia cell line with $IC_{50}$ value of $2.75{\pm}0.32{\mu}g/mL$. To the best of our knowledge, guangsangon E (1) and sorocein I (3) were reported for the first time from the tissue cultures of M. macroura.

  • The effect of cadmium ions on ligninolytic and decolourizing activities in cultures of two white-rot fungi, Cerrena unicolor and Trametes versicolor, were examined. Cadmium was added to the shallow stationary cultures growing on a liquid mineral medium. Both examined strains sorbed Cd ions in the first 24 hr of incubation. An appreciable stimulation of the activity of extracellular laccase (LAC) and inhibition of the extracellular manganese-dependent peroxidase (MnP) were simultaneously observed when 25 mgL-1 and 50 mgL-1 of cadmium ions were added to the cultures. On the other hand, the addition of cadmium ions also resulted in stimulating the decolorization activity of C. unicolor to decolorize Remazol Brilliant Blue R (RBBR) in the cultures, but decreasing it in the culture of T. versicolor, which is compared to the inhibition of MnP activity in this fungus. Our data indicate that the presence of Cd(II) ions can affect the ligninolytic activity of white-rot fungi. It was found that C. unicolor is a strain resistant to the presence of Cd ions in the liquid culture media, and has a potential to use this strain for bioremediation of sites contaminated with both heavy metals and aromatic pollutants.

  • Knowledge management (KM) is one of the useful management tools in today's project management (PM) practice, such as construction projects. Nobody can deny the importance of "useful knowledge" always helps organizations and project managers shaping a decision. Due to the trend of globalization, it is now very common that an organization may comprise employees from different countries of distinct national-cultures working together. It is also not uncommon that different projects, within an organization, may have their own organizational-cultures which influence its knowledge repository, transfer process and knowledge strategy. Therefore, it is extremely difficult to align all these cultures and consolidate them to benefit the KM process and PM practice. Organizations and project managers understand that different national-cultural and organizational-cultural factors will create impact on the philosophy of KM process which will subsequently affect PM practice. Those factors may affect interpersonal relations and exchange of knowledge between projects and amongst staff. Systematic KM process can utilize the goodness of different employees from distinct cultures which can eventually drive the organization and projects to success. The purpose of this paper, based upon a case study of a Hong Kong construction company, is to discuss how those cultural factors are linked to KM and what organization and project managers can do to improve the KM process and PM practice.
