This study examines the effectiveness of the study through a case of PBL(problem-based-learning) class conducted in a balanced culture course called at 00- University in the second semester of 2020. The effects of learning are as follows: First, PBL(problem-based-learning) has sufficient active interaction between the teacher and the learner. In the face of prolonged non-face-to-face learning, the PBL teaching method has sufficient interaction between the professors-learner and the learner. Second, PBL learning can actively utilize various problems that fit the characteristics of the subject and actively utilize the process of role sharing and collaboration. By presenting various problem situations suitable for the subject, students will be able to share roles individually or as a team, and fully experience the process of collaboration and discussion in the process of investigating the data. Third, critical perceptions of problem situations can be extended. In modern times, a variety of problem situations arise and critical perceptions of them must be fully learned. In a mass production and mass consumption society, students should develop the ability to blindly recognize and distinguish between real and fake information in a flood of information. The limitations identified in this class case are, first, the nature of the subject, "Understanding Culture and Philosophy," which makes it possible to discuss the global cultural phenomenon, but it should be discussed in terms of philosophy. Second, it is not easy to work as a team on non-face-to-face online. Nevertheless, PBL is a very effective method of learning in which active interactions and learning activities take place between professors and students, whether face-to-face or face-to-face online learning.

Clostridium butyricum, Lactobacillus amylophillus, Lactobacillus amylovorus, Lactobacillus acidophillus, AI-9 produced hydrogen and /or organic acids using glucose, lactose and starch at the anaerobic culture conditions. Cl. butyricum NCIB 9576 evolved 1,700 ml H2/L-culture broth and accumulated butyric acid, acetic acid, propionic acid and ethanol in its culture broth when lactose was used as a carbon source during 24 hrs of fermentation. L. amylovorus ATCC 33620 accumulated lactic and acetic acids and some reducing sugars when starch was used as a carbon source without hydrogen production. Instead of starch as a carbon source, L. amylovorus ATCC 33620 produced lactic acid from algal biomass during fermentation and the acid-heat or freeze-thaw pretreatment of algal biomass accelerate the lactic acid fermentation.

In the present study, the biomass productivity of two green microalgae (Chlorella sp. and Dunaliella salina DCCBC2) were assessed in a 12 L tubular photobioreactor under optimum culture conditions. In the batch culture optimization process, the Chlorella sp. biomass was obtained as 1.2 g/L under atmospheric air as a sole $CO_2$ source and other culture conditions as follows: light intensity, temperature, pH, $NH_4Cl$ and $K_2HPO_4$ were 100 ${\mu}E/m^2/s$, $27^{\circ}C$, 7.0, 20.0 mM and 2.0 mM, respectively. On the other hand, 2.9 g/L of D. salina DCCBC2 biomass production was observed under the following conditions: light intensity, temperature, pH, $KNO_3$ and $K_2HPO_4$were 80 ${\mu}E/m^2/s$, $27^{\circ}C$, 8.0, 3.0 mM and 0.025 mM, respectively. At 1% $CO_2$ supply to the reactor, the Chlorella sp. production was reached 1.53 g/L with 25% increment under the same operating conditions. In addition, the maximum D. salina DCCBC2 biomass was observed as 3.40 g/L at 3% $CO_2$ concentration. Based on the aforementioned optimized conditions, the dilution rate and maximal biomass productivity of Chlorella sp. and D. salina DCCBC2 in the continuous cultivation were 0.4/d and 0.6 g/L/d and 0.6/d and 1.5 g/L/d, respectively.

Fed-batch fermentations with different feeding media were carried out in order to increase the productivity of invertase expression using a recombinant Saccharomyces cerevisiae containing plasmid pRB58. Two batch cultures showed the expression of the SUC2 gene at a low concentration of glucose, suggesting that glucose concentration could be used as a control variable in a fed-batch operation mode. In the fed-batch culture by feeding the basal medium, cell mass and specific invertase activity did not increase much as compared with the simple batch culture. A series of fed-batch cultures revealed that the sucrose-supplemented medium increased cell mass whereas the enriched medium did specific invertase activity. To capitalize on the synergism of the sucrose-supplemented medium and the enriched medium, the sucrose-supplemented enriched medium was used as a feeding medium. The fed-batch culture using this medium resulted in a 2.4-fold increase in cell mass and a 1.9-fold enhancement in specific invertase activity compared with those of the batch culture. The increase in cell mass and specific invertase activity led to a marked increase in total invertase activity, 250U/ml, which was 6.3 times higher than that of the batch culture.

Mental health is attributed to person's well-being, abilities and productivity. The purpose of this study is to suggest the effects of K-culture to people in adversity. It is PungmulPanGut, represented by traditional Korean play culture. Pungmul is a performance with four percussion instruments, Janggu (Korean hourglass drum), Buk (barrel shaped drum), Jing (large gong), Kkwaenggwari (small gong), and play. In Korean, "pan" means that it's a place to do something. Gut means to make a wish. The ensemble Better Than Medicine (eBTM) is a team that has trained and worked with Gamuak (歌,舞,樂; singing, dancing, playing) for a long time, but is not perfect (we refer this as 2% lacking in music). The characteristic of our team is that we share joy while voluntarily participating and doing what we like. It is a combination of singing, dancing, playing musical instruments, and exciting people. There is wind-like energy and there is mutual cooperation, not competition. As we concentrate, we become immersed in each other's breathing and movement. So it makes us forget the hard situation, the hardships, the pain, and so on. In the meantime, our pleasures peak and share happy energy with each other. Even though we are two percent less skilled, our sense of happiness doubles. Music together is not competition but cooperative work and healing. Therefore, we suggest that PungmulPanGut can be better K-culture than medicine in promoting mental health.

As movies and dramas which show traditional clothes and fusion clothes are getting popular these days, lot of people are paying attention to these dress and ornaments. And as for the domestic collections which seem to reflect this trend, various fusion style clothes are getting widely adopted by people. Therefore, this study analyzed and considered the clothes designs when the country started to open itself to other countries, by selecting a movie titled "YMCA baseball team", a movie to ascertain vigorous historical verification, and by conducting the prior study and using the DVD capture program. This study is meaningful in that based on the comparison study on the costumes, it clarifies the degree of costumes(clothes) acceptance at the point of nation's opening to other countries, which is the source of fusion style, and further shed light on the role that the movie costumes will play. From this study, we can get the following conclusions. First, through the theoretical background it can be known that when the country opened itself to outside world the dress and ornaments of the time was adopted in a top-down way, namely, first adopted by the royal family and the upper class, which could have easy access to the western civilization and institutions, and then the low class later. Second, in the movie titled 'YMCA baseball team' the costumes were designed through the strict and thorough historic verification, and it can be confirmed that various dress and ornaments adopted at the time of nation's opening to the outside world centered around the clothes design for new women. Third, 'YMCA baseball team is evaluated as a movie that reproduces that time well and as a media that provides an effective clue to the dress and ornaments adopted by the public when the country opened itself to the outside world.
