This study was carried out to examine on developmental competence of Hanwoo embryos cultured in vitro according to culture conditions and freezing methods. The in vitro developmental competence to blastocyst stage at Day 8 of culture in SOF was significantly (p<0.05) higher than that in CR1aa (30.3% vs. 18.4%). The in vitro developmental rate of morula and blastocysts cultured in group culture was significantly (p<0.05) higher than that in individual culture (41.4% and 36.0% vs. 21.1% and 10.5%, respectively). The cell number of Day 8 blastocysts in group culture was significantly (p<0.05) higher than that in the individual culture ($120.1{\pm}12.8\;vs.\;94.1{\pm}12.1$, respectively). The survival rates of frozen-thawed balstocysts that were exposed in 1.5 M ethylene glycol or 1.5 M ethylene glycol containing 0.1 M sucrose were 77.5% and 78.7%, respectively. The survival rates of blastocysts cultured for 48 h in slow freezing and vitrification was not significantly different (73.3 and 74.0%). In conclusion, in vitro developmental competence of bovine embryos was influenced on the culture medium (SOF) and culture method (Group culture). Survival rate of frozen-thawed of bovine embryos was not influenced on freezing solutions and freezing methods.

Flowering date of peanut variety, Daekwangtangkong and Daepungtangkong in non-mulching culture was delayed each 9 and 6 days. Seedling ratio was decreased each 3.7%, 16% and branch length was decreased each 24%, 17% more than polyethylene film mulching culture. But the number of branch in non-mulching culture was not reduced. No. of mature pods, kernel/pod ratio, 100-seed weight and kernel weight per plant was reduced extremely in non-mulching culture, nevertheless the kernel yield per 1 ha of Daekwangtangkong in non-mulching culture was similar to that of polyethylene film mulching culture but yield of Daepungtangkong was 26% higher than that of polyethylene film mulching culture owing to planting density. Protein content of Daekwangtangkong in non-mulching culture was increased 4% but that of Daepungtangkong was decreased 3% and oil content of both variety was decreased 7%, 9% respectively comparing to polyethylene film mulching culture. Oleic acid was increased but linoleic acid was decreased and O/L ratio was decreased in non-mulching culture.

Objectives : This study was to investigate the level of organizational culture and self-leadership on organizational effectiveness and the significant factors influencing organizational effectiveness in oral health professional. Methods : Data were obtained from a cross-sectional survey of 297 oral health professional(mean age=$29.95{\pm}8.10$). Participants in the study were recruited when they attended the dental health form in Gwangju. Organizational culture was classified into four factors: relation-oriented, innovation-oriented, hierarchy-oriented, task-oriented culture. Self-readership consisted of five factors: rehearsal/self-observation, self-goal establishment, self-esteem, self-criticism, self-reward. Organizational effectiveness included organizational commitment and job satisfaction. The data was analysed using t-test, one-way ANOVA, Pearson correlation and multiple regression. Results : The dominant organizational culture was rank-oriented culture. The mean score of self-readership score was 3.51 out of a maximum 5 points. Organizational commitment was positively correlated with age, relation-oriented culture, self-goal establishment, self-reward explained 41.9% and job satisfaction was positively correlated with relation-oriented culture and self-esteem explained 48.6%. Conclusions : Based on the findings, the organizational culture and self-readership was correlated with organizational effectiveness.

In this study, we investigated the effect of solid culture medium on the production of cordycepin in Cordyceps militaris. The regression equation was expressed as follows: Y₁ = 755.3-58.6625X₁+4.79432E-14X₂-46.6625X₃-5.66269E-14X₁X₂-0.025X₁X₃+1.62475E-14X₂X₃-160.6625X₁²+0.0125X₂²-206.9625X₃², where, Y represents the value of cordycepin content (㎍/g), X₁ corresponds to the weight of M. alternatus in solid culture medium (g/bottle), X₂ to the water content of the solid culture medium (%), and X₃ to the culture period (day). The solid culture medium was optimized using the response surface methodology, and the optimal medium composition was as follows: the weight of M. alternatus in solid culture medium and water content were 16.2% and 100.7% (20.14 mL water/20 g solid culture medium), respectively, with a culture period of 39 days. Under these conditions, the cordycepin content of the fruiting bodies reached 150.0 ㎍/g (actual value). The supplementation of M. alternatus in solid culture for improved cordycepin content of C. militaris seems to be a promising alternative to wild and solid cultivation.

Hallyu pop-culture contents which has influenced the world has sufficient preservation value as a cultural asset. However, there is still a lack of awareness of long-term preservation of Hallyu pop-culture contents and digital archiving is not in full swing, too. We requires accurate understanding of the concept, characteristics, format, media, and relationship of contents for digital archiving of Hallyu pop-culture content. Thus, this study analyzed and organized the concept, characteristics, and preservation subject of Hallyu pop-culture contents, as basic study for digital archiving of Hallyu pop-culture contents. In addition, we investigated the current status of digital archives (systems/institutions) of Hallyu pop-culture contents and Hallyu pop-culture contents, and presented basic proposal based on the problem factors.

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.

The present study was done to investigate the effect of co-culturing muscle satellite cells (MSCs) and intramuscular preadipocytes (IPs) on the differentiation of adipocytes and muscle cells isolated from Korean native cattle. MSCs and IPs were single-cultured in 10% fetal bovine serum/Dulbecco's modified Eagles medium (FBS/DMEM) for 48 h followed by culturing in 5% FBS/DMEM as the growth media. Then, the growth media was replaced by differentiation media composed of 2% FBS/DMEM without any additives for the single- or co-culture of muscle cells and intramuscular adipocytes to induce the differentiation of both cell types. Cell differentiation was measured by morphological investigation and cytosolic enzyme analysis of glycerol-3-phosphate dehydrogenase (GPDH) for the adipocytes and creatine kinase (CK) for the muscle cells. In the morphological test, the presence of muscle cells did not stimulate adipocyte differentiation showing more differentiation of the adipocytes in the single-culture compared to the co-culture condition. However, the differentiation of muscle cells was promoted by adipocytes in the co-culture. The results of the enzymatic analysis were highly associated with the morphological results with a statistically higher GPDH activity (p < 0.05) appearing in the single-culture than in the co-culture, whereas the opposite was true for the CK activity of the muscle cells (p < 0.05). By manipulating in vivo the milieu using a co-culture, we could detect the difference in the rate of cell differentiation and suggest that a co-culture system is a more reliable and precise technique compared to a single-culture. Further studies on various co-culture trials including supplementation of differentiating substances, gene expression analysis, etc. should be done to obtain practical and fundamental data.

Purposes: In this study, we examined the factors which silenced the organizing members and how the factors affects deprivation of employment about the organization culture, the organizational silence, and the turnover intention. Methodology: In order to research, we carry out a survey on 400 employees of small and medium hospitals. Among them, 321 questionnaires were used for actual analysis, excluding insincere respondents, non-responders or duplicate respondents. In order to verify the hypotheses in this study, we conduct the covariance Structural Equation Model(SEM). Finding: We obtained results using following hypotheses. First, ''The organization culture has an effect on the turnover intention.'' Second, ''The organization culture has an effect on the organizational silence'' Third, ''The organizational silence has a influence on the turnover intention.'' Finally, ''When the organization culture mediates the organizational silence, the adaptation relationship of the ornization effectiveness is different.'', as the key hypothesis, showed that the agreement culture, rational culture, and hierarchical culture of the organization culture type were statistically significant. The organizational silence as a parameter has the partial mediating effects(-) because it has direct and indirect effects. Practical Implications: The results of this study showed that the reason for the organizational silence of the organizing members is that the organization culture by a grade of rank is the largest and these the organizational silence affects the turnover intention.

The purpose of this research is to examine the relationships among data literacy, organizational culture, and data analytics maturity and the moderating effects of organizational culture. Analysis of the relationship between data literacy and data analytics maturity shows that the higher the data literacy competency of employees, the higher the organization's data analytics maturity. In examining the relationship between organizational culture and data analytics maturity, it is found that relationship culture and innovation culture are positively related to data analytics maturity. In addition, relationship culture and hierarchy culture show significant moderating effects. Relationship culture shows a synergistic effect, whereas hierarchy culture has a buffer effect between data literacy and data analytics maturity.
