The acid response of Bifidobacterium longum subsp. longum BBMN68 has been studied in our previous study. The fab gene, which is supposed to be involved in membrane fatty acid biosynthesis, was demonstrated to be induced in acid response. In order to investigate the relationship between acid response and cell membrane fatty acid composition, the acid adaptation of BBMN68 was assessed and the membrane fatty acid composition at different adaptation conditions was identified. Indeed, the fatty acid composition was influenced by acid adaptation. Our results showed that the effective acid adaptations were accompanied with decrease in the unsaturated to saturated fatty acids ratio (UFA/SFA) and increase in cyclopropane fatty acid (CFA) content, which corresponded to previous studies. Moreover, both effective and non-effective acid adaptation conditions resulted in decrease in the C_18:1 cis-9/C_18:1 trans-9 ratio, indicating that the C_18:1 cis-9/C_18:1 trans-9 ratio is associated with acid tolerance response but not with acid adaptation response. Taken together, this study indicated that the UFA/SFA and CFA content of BBMN68 were involved in acid adaptation and the C_18:1 cis-9/C_18:1 trans-9 ratio was involved in acid tolerance response.

The aim of this study was to investigate on characteristics of sociological and demographic population, marital conflicts and expectations to family counselors' cultural competence surrounding factors of cultural adaptation among immigrated women. This study conducted a survey of 236 immigrated women in Kyonggi province, Seoul metropolitan cities, Cholla and Chunchung provinces and Incheon. The results of this study are as follows: First, a relatively few marital conflicts were found, as a whole, while they had the high levels of expectation to family counselors' cultural competence. Second, immigrated women can be clustered as three different types: 'multiplicity type', 'undifferentiated type' and 'adaptation type'. Third, sociological and demographic population characteristics which were subdivided and clustered according to cultural adaptation made the significant difference between each population. Population with multiplicity type out of the above-stated three types accounted for the highest conflict rates, while population with 'adaptation' type accounted for the lowest conflict rates. Lastly, expectations to family counselors' cultural competence made the significant difference among each population. Population with multiplicity type showed the highest expectation levels on expectations to family counselors' cultural competence, while population with undifferentiated type showed the lowest levels.

The purpose of this study is to analyze the structural relationship and direct and indirect effects among high school students' self-esteem, democratic parenting attitude, school adaptation, and human rights awareness. The subject of this study is panel data of a total of 3,456 high school students who responded to a study on the implementation of the Convention on the Rights of Children and Youth of the Korea Youth Policy Institute. Data analysis was statistically processed using SPSS 21 and AMOS 21.0 programs. The results of this study showed that high school students' self-esteem had a direct effect on democratic parenting attitudes, school adaptation, and human rights awareness. It was confirmed that the self-esteem of high school students had an indirect effect on human rights awareness through democratic parenting attitudes and school adaptation as a medium. In conclusion, in order to improve high school students' human rights awareness, school of social work is needed considering the causal relationship of all variables.

Mammalian cell cultures have been used extensively to produce proteins for therapeutic agent because of their ability to perform post-translational modification including glycosylation. To produce recombinant protein, many factors and parameter are considered such as media composition, host cell type, and culture process. In this study, recombinant human erythropoietin (rhEPO) producing cell line was established by using glutamine synthetase system. To reduce serum concentration in media, we compared direct adaptation with step adaptation. Cell growth was faster in step adaptation. In low-level serum media, there were insufficient glucose for cell growth. Thus, we added glucose in low-level serum media from 2 g/L to 4.5 g/L. Titer of rhEPO was higher than other conditions at 4.5 g/L of glucose. Additionally, N-methyl-D-aspartate (NMDA), 13-cis-retinal, and pluronic F-68 (PF-68) were added to enhance productivity in CHO cell cultures. In conclusion, we applied CHO cell producing rhEPO to low-level of serum in media using step-adaptation. Also, we confirmed positive effect of NMDA, 13-cis-retinal, and PF-68.

Recently, several studies have been conducted to lower the cost of transport of human by adding external joint stiffness elements. However, it has not been clearly elucidated whether adaptation time is required for human subjects to adapt to the added external joint stiffness. In this study, carbon plates in the form of shoe midsoles were added to the metatarsophalangeal joint, and the lower limb joint torque and mechanical energy consumption were compared before and after a total of 5 sessions (2.5 weeks) of running. A total of 11 young healthy participants exhibited higher elastic energy storage in carbon plates in the fifth session compared to the first session, and lower power in the ankle joint. This suggests that a single training session may be insufficient to validate the efficiency effect of added joint stiffness, and the human body seems to increase the elastic energy stored in the assistive joint stiffness and its reutilization.

This study aims to compare the husband's stress, communication, family cohesion and adaptation which contribute to the internal structure of conjugal understanding between families living apart from one another and those living together. The data for analysis was derived from questionnaires. 172 husbands from families living apart and 185 husbands who live with their families. The data was treated by spss pc+ program and the methods of analysis were frequency, t-test and one-way ANOVA. The results of this study were as follows : 1. Husband's stress in conjugal understanding in families living apart was higher than those who live with their families. 2. Between the husbands whose families are living apart and those who are living together, there were no significant differences in effort levels to overcome stress, family cohesion, family adaptation and communication needs for conjugal understanding. 3. Husbands who live with their families communicate differently according to the degree of their stress levels. 4. Low stress levels led to high family cohesion and family adaptation in both cases. 5. High communication levels led to high family cohesion and family adaptation in both cases.
