Plant tissue culture studies have been done for the preservation of medicinal plant resources and efficient production of pharmaceutically important secondary metabolites. Micropropagation methods for Cephaelis ipecacuanha have been established and these methods enabled much more efficient propagation of the plants than the conventional methods using seedling or layering. The C. ipecacuanha plants derived from tissue culture grew uniformly in the field and they showed higher alkaloid contents compared to the plants grown from seedlings. Hairy root cultures of C. ipecacuanha and Panax ginseng have been established by infection with Agrobacterium rhizogenes, and the production of important pharmaceuticals by these cultures have been successfully demonstrated. In the case of C. ipecacuanha, the highest alkaloid yields from the hairy roots cultured for 8 weeks were 2.75-fold cephaeline (5.5 mg) and one third emetine (0.7 mg) compared with those from the roots of one-year old plant propagated through shoot-tip culture and cultivated in a greenhouse (2.0 mg cephaeline and 2.0 mg emetine). In the case of P. ginseng, ginsenoside contents in the hairy roots optimally cultured for 4 weeks were much higher than those in the roots of 4-year old field-grown plant. Thus our medicinal plant tissue cultures demonstrate desirable properties. However, they are always exposed to danger of microbial contamination or unexpected trouble of culture facilities. Cryopreservation of plant tissue cultures is a reliable method for long-term preservation. Cryopreservation studies on these cultures are also presented.

This study aimed to examine the differences in gender equality consciousness between latent profiles based on corporate workers' organizational culture types. To achieve the study's purpose, descriptive statistics, correlation analysis, and latent profile analysis (LPA) were conducted using 253 Korean corporate workers' data. As a result of the analysis, the latent profiles of organizational culture recognized by corporate workers were classified into 5 profiles. We named each profile as high compete-low create culture, high compete-low collaborate culture, collaborate culture, high create culture, and high control culture based on each profile's organizational culture perception. The ANOVA test found statistically significant differences between the groups in the gender equality consciousness. This study is meaningful in that it reveals the relationship between the organization culture perception and the gender equality consciousness and suggested implications for the organizational-level intervention to improve the gender equality consciousness. It will provide basic data for your research.

This study investigated the effects of the addition levels of white kimchi powder and acerola juice powder, as natural sources of sodium nitrite and sodium ascorbate, on the quality of cooked ground pork products. Freeze-dried white kimchi powder was prepared and used after fermentation for 2 wk. Six treatments were included: control (100 ppm sodium nitrite and 500 ppm sodium ascorbate), treatment 1 (0.2% white kimchi powder, 0.02 % starter culture, and 0.1% acerola juice powder), treatment 2 (0.2% white kimchi powder, 0.02% starter culture, and 0.2% acerola juice powder), treatment 3 (0.4% white kimchi powder, 0.04% starter culture, and 0.1% acerola juice powder), treatment 4 (0.4% white kimchi powder, 0.04% starter culture, and 0.2% acerola juice powder), and treatment 5 (0.4% celery powder, 0.04% starter culture, and 0.2% acerola juice powder). The pH values were decreased (p<0.05) because of lower pH of acerola juice powder, resulting in lower cooking yields (p<0.05) in these treatments. CIE L* and CIE a* values of indirectly cured meat products were not different (p>0.05) from the sodium nitrite-added control. However, indirectly cured meat products showed lower (p<0.05) residual nitrite contents, but higher (p<0.05) nitrosyl hemochrome contents and cure efficiency than the control. Treatments 2 and 4 had higher (p<0.05) total pigment contents and lipid oxidation than the control. This study indicates that white kimchi powder coupled with acerola juice powder has substantial potential to substitute synthetic nitrite to naturally cured meat products, which could be favored by consumers seeking clean label products.

The main purpose of this study is to investigate foreigners' perception regarding Korean business culture and Korean business culture education. People who participated in this study are six foreign workers after studying at the university or graduate school in Korea. A phenomenological qualitative research method was used in this study in order to elicit life experiences from foreign workers who were working in Korea business companies. Therefore, their experience regarding Korean business culture and business culture education were measured by in-depth interviews. This study shows that nun-chi, vertical relationships, and impatience of Koreans are the most difficult culture to foreign workers. They also feel difficulties regarding Koreans' lack of understanding about other cultures. Moreover, these were not difficult components within school life; rather, the most difficult aspects were that they have never learned about the Korean business culture before getting a job. The results show that international students who want to work in Korea companies need to study about the culture of Korean business and revealed the desirability to learn. These results can be used as a foundation for understanding some contents and criterion of Korean business culture and education.

Public policies in regard to developing reading culture programs and the contents, and in running public libraries have been used to overcome existing social issues such as regional self-centeredness and cultural lagging. It means that public libraries are playing an important role to encourage communications within local communities. The purpose of this research is therefore to analyze the concept of local community, and develop reading culture and contents to reinforce the concept. This research also targeted to analyze the required contents in reading culture. Through the case study of "G" city, the research analyzed their citizenship and sense of local community and the requests. As a result, the requited subjects were for economics, unemployment, poverty, aging, and housing order. For the subjects of environment were environment pollution and energy order. For the subjects of human rights, disabilities, and multi-cultural were requested. For the subject of education, school violence, tutoring, and truly teaching were requested. Based on the requirements, 221 items of reading lists, DVD clips, and abstracts are developed as well as 4 programs of reading culture.

This study was conducted to investigate the antioxidant activity of Jeolpyeon containing lotus seed powder. Original Jeolpyeon and Jeolpyeon with BHT (butyl hydroxy toluene) werecompared. Antioxidant activities were measured based ontotal polyphenolic contents, total flavonoid contents, DPPH radicalscavenging activity, reducing power, and SOD-like activity. Total polyphenolic and total flavonoid contents of Jeolpyeon containing lotus seed powder were estimated at $37.81{\pm}0.45$ mg GAE/g and $26.35{\pm}0.13$ mg QE/g respectively. DPPH radical scavenging activity increased upon addition of lotus seed powder. Further, reducing power was higher in Jeolpyeon containing lotus seed powder than original Jeolpyeon or Jeolpyeon with BHT. The antioxidative effect of Jeolpyeon significantly increased uponaddition of lotus seed powder.

Fatty Acid contents of entomopathogenic nematodes(EPNs) were examined by various types of nematodes and culture methods. Seven different types EPNs cultured by in vivo did not contain same fatty acid contents, but similar compositions. It was also found that Steinernema carpocapsae among EPNs cultured by in vivo and in vitro contained not only different fatty acid contents, but also revealed distinctive motilities in a soil. The addition of olive oil in the in vitro culture medium resulted in similar fatty acid contents of S. carpocapsae to in vivo and greatly improved the pathogenicity of nematodes compared to that of soy oil in the medium.

In the midst of the fusion era in digital contents, securing a variety of traditional cultural sources is important. Out of its long history, Korea has extensive spectrum of cultural contents in combination with conventional religions. Buddhist art has been a pillar of the traditional culture for a long time in Korea, by which we could secure new sources for cultural contents and classify them. This is aimed that we could bring the future brands into reality based on the traditional culture through Buddhist cultural contents. This study hired the original cultural forms in the viewpoints of traditional culture. Study on the implication through the symbols of Avalokitesvara (觀音菩薩) and Buddhist child (童子) in Buddhist art might allow to secure a foothold to create own characters. Thus, focusing on Avalokitesvara (觀音菩薩) and Buddhist child (童子) in the Buddhist sacred images as registered in Cultural Heritage Administration for national treasures, those traditional characters were reviewed through their own system of symbol. During the course, Buddhist characters were available to be classified into DB by their roles and materials지물. This study could help to exploit the complicated Buddhist culture of its symbolic meanings and to shape them into original forms of the culture. Also, through the meanings of the Buddhist sacred images, it could provide the digital contents pool with Korean traditional characters.
