The content that is actively consumed in popular culture today is definitely the 'Zombie Narrative'. 'Zombie' is soon positioned as a unique character that reveals the times in which we live in conjunction with the uniqueness of Korean society. Zombies, however, are rarely narrated in traditional Korean modern novels though science-fiction novels constructively deal with them. This paper focuses on the existence of 'zombie', which seldom appears in modern novels. The paper also aims to illuminate the literary value of the 'zombie narrative' that is explosively consumed in modern society. In the main part, I talk about the horrors of 'ignorance' appearing in the existence of zombies in relation to those of the problem concerning "unknown". As one of the crucial characteristics of the zombies, moreover, the "absence" of the "thinking" was considered in terms of "ignorance" in relation to the concept of "Banality of evil" raised by Hannah Arendt. This paper also pays attention to the possibility of a new solidarity between zombies and humans depicted in novels. This possibility can be seen as a search for solidarity between humans and zombies, beyond the solidarity between humans who survived from zombies. The paper enlightens a new relationship between a captor and a captive that dichotomous scale impossibly explains and presents a possible new story. As discussed above, as this study searches for the existence of 'zombies' that seldom appear in contemporary Korean novels, it clearly signifies the literary value of 'zombies' and further possible narratives concerning 'zombies'. Furthermore, this study appreciates the extension of the existing 'zombie narrative' researches, which has been mainly focused on films.

An experiment was conducted to investigate the effects of varying levels of hydrolyzed yeast on egg production and egg quality in aged laying randomly allotted to three dietary treatments such that egg production was similar in each treatment (6 replicates of 10 birds each). The layers were fed diets containing 0, 0.1, or 0.2% hydrolyzed yeast for eight weeks. No significant difference was observed in egg production during the first half of the experiment. Egg production and daily egg mass in groups fed diets containing hydrolyzed yeast were significantly higher (P<0.05) than those of the control groups during the second half of the experiment. Egg weight was not affected by the dietary treatment. Eggshell strength and thickness in groups fed diets containing hydrolyzed yeast were significantly higher than those of the control groups during the overall experimental period (P<0.05). Although no significant differences were observed in the Haugh units, yolk color in the group fed diets containing 0.1% hydrolyzed yeast was significantly higher than that in the control group (P<0.05). The mammillary layer thickness increased in a linear manner and significantly following treatment with dietary hydrolyzed yeast (P<0.05). Antibody titer against avian influenza virus in the group fed diets containing 0.2% hydrolyzed yeast was significantly higher (P<0.05) than that in the control group. In conclusion, dietary hydrolyzed yeast improved egg production and eggshell quality of laying hens in the late stages of production.

Arsenic (As) contamination in groundwater is one of the main problems in Bangladesh. As toxicity causes serious human health problems such as edema, skin cancer, bladder cancer, lung cancer, hyperkeratosis, premature birth, and black foot disease. As contamination in groundwater mainly originates from the geological characteristics of the area due to the influence of anthropogenic activities. Since most of the people in Bangladesh rely on tube well for drinking water, it is necessary to investigate the current status of As pollution and identify the treatment technologies that can be used to provide arsenic-free drinking water in water-scarce areas. A total of 92 papers were reviewed in this study to present a complete overview of the recent status of groundwater As contamination in Bangladesh and different low-cost remediation technologies. A method for evaluating the relative feasibility of different treatment technologies was also utilized to determine the most appropriate technologies for groundwater As treatment in Bangladesh. The districts with the highest groundwater As contamination include Brahamanbariya, Tangail, Barisal, Pabna, Patuakhali, Kurigram, Magura, and Faridpur, with concentrations exceeding 0.05 mg/L. Only six districts had relatively low groundwater arsenic concentrations (0.01 mg/L), including Kushtia, Khagrachari, Jessore, Dinajpur, Meherpur, and Munshiganj. There were a number of technologies used for treating As in water, but aerated electrocoagulation, Mg-Fe-based hydrotalcite-like compound, and electro-chemical As remediation (ECAR) reactor were found to be the most feasible treatment methods for As. Overall, the investment, operational, and maintenance costs, availability of materials, and expertise requirements should be considered when selecting the most appropriate treatment method for As in water.

Objectives : Gambigyeongsinhwan 16 (GGEx16), gambigyeongsinhwan 18 (GGEx18) and gambitongseong capsule are shown to be involved in the regulation of obesity. Therefore, the aim of this study was to compare the reporter activity of anti-obesity genes such as peroxisome proliferator-activated receptor ${\alpha}$ ($PPAR{\alpha}$) and $PPAR{\delta}$ by GGEx16, GGEx18 and gambitongseong capsule. Methods : After NMu2Li liver cells, C2C12 skeletal muscle cells and 3T3-L1 preadipocytes were treated with GGEx16 (1 ${\mu}g/ml$), GGEx18 (1 ${\mu}g/ml$) and different concentrations of gambitongseong capsule, the transactivation of $PPAR{\alpha}$ and $PPAR{\delta}$ was measured by a luciferase reporter gene assay. Results : $PPAR{\alpha}$ reporter gene activity in NMu2Li liver cells and 3T3-L1 preadipocytes was significantly increased by GGEx16, GGEx18 and gambitongseong capsule compared with control, whereas $PPAR{\alpha}$ reporter gene activity in C2C12 skeletal muscle cells was significantly increased by GGEx18 only compared with control. Similarly, $PPAR{\delta}$ reporter gene activity in 3T3-L1 preadipocytes was also significantly increased by GGEx18 compared with control. $PPAR{\delta}$ reporter gene activity in C2C12 skeletal muscle cells was significantly increased by GGEx16 and GGEx18 compared with control although $PPAR{\delta}$ reporter gene activity in NMu2Li liver cells was not changed by these three formulas. Conclusions : These results suggest that all three formulas have the ability to stimulate $PPAR{\alpha}$ and $PPAR{\delta}$ transactivation in animal cell lines with high metabolic rates. In particular, this effects were most prominent in GGEx18-treated cells. In addition, it is likely that GGEx18 may be used as an effective anti-obesity composition.

The purpose of the research was to examine the effect of field of view on egocentric distance perception in the real and virtual environment. The replica that mimicked the real environment condition was used to create the virtual environment condition. We manipulated field of view levels equally in both viewing conditions using glasses that limit the field of view in real-world conditions and limiting the field of view in virtual-world conditions in a manner equivalent to real-world conditions via HMD. Eighteen participants observed the target with a limited field of view in a real and virtual environment without head movement. Then, we measured perceived distance using the timed imagined walking method, which measures the time taken by each participant to mentally walk to the target. The target was shown three times at three different distances from the participants: 3, 4, and 5 m. For the analysis, we converted time estimates into distance estimates. Consequently, the estimated distance in the virtual environment condition was less than the estimated distance in the real environment condition. And as the field of view shrank, the estimated distance also decreased. The estimated distance did not vary with field of view levels in real-world conditions. In the virtual environment, the estimated distance decreased as the field of view decreased, whereas in the real environment, the estimated distance increased. The implications of the results and some future research directions are discussed below.

Background: New beauty soaps are always subject to evaluation. Purposes: This study performed a human application test and safety evaluation on the cleaning effect of the fine dust mimic of the test product, Daziwar soap bar, on 52 women. Methods: The quantitative change measured the cleaning effect of fine dust before and after washing immediately after spraying the fine mimetic dust on the forearm of 22 women. In addition, the safety was evaluated at 30 minutes, 24 hours, and 48 hours after 24 hours after applying the patch to the woman's back. Results: After one time washing with the soap immediately after spraying dust on the inside of the arm, the amount of the remaining mimetic was statistically significantly decreased in both the test group and the control group (p < .001). However, the washing rate was 99.96% in the experimental group and 75.58% in the control group. The questionnaire was evaluated as 'Good' or higher in terms of efficacy. In the evaluating of adverse reactions after washing fine dust by a dermatologist, there were no reports or observations of specific skin adverse reactions or abnormal findings in the subjects. The safety evaluation was judged as non-irritating in the skin reaction evaluation at 30 minutes, 24 hours, and 48 hours after instillation on the back for 24 hours. Conclusions: The test product, Daziwar soap, was found to be very helpful in cleaning fine dust on the human body and was found to be safe for the human body.

In general, the performance of ML(Machine Learning) application is determined by various factors such as the type of ML model, the size of model (number of parameters), hyperparameters setting during the training, and training data. In particular, the recognition accuracy of ML may be deteriorated or experienced overfitting problem if the amount of dada used for training is insufficient. Existing studies focusing on image recognition have widely used open datasets for training and evaluating the proposed ML models. However, for specific applications where the sensor used, the target of recognition, and the recognition situation are different, it is necessary to build the dataset manually. In this case, the performance of ML largely depends on the quantity and quality of the data. In this paper, training data used for motion recognition application is augmented using the kernel density estimation algorithm which is a type of non-parametric estimation method. We then compare and analyze the recognition accuracy of a ML application by varying the number of original data, kernel types and augmentation rate used for data augmentation. Finally experimental results show that the recognition accuracy is improved by up to 14.31% when using the narrow bandwidth Tophat kernel.

Power and status are core elements that distinguish social classes and strongly influence social interaction. Although they are the foundation of social influence, they have different origins (Fragale et al., 2011). While power usually is based on personal ability or legal, institutional legitimacy, status is rooted in voluntary support from other people. Hence, whereas people with power often demonstrate egoistic behavior, those with high status show relationship-based altruism (Hasty & Maner, 2020). People recognize the difference between the two and have stereotypical beliefs or expectations about the people's behavior with high power or status (Magee, 2009). The current research tested how the judgment on social exclusion, the unique social influence of power and status, changes depending on the actor's power and status. We constructed social exclusion scenarios in which we manipulated actors' power and status and asked participants to rate an actor's pain and behavioral fairness. Participants' ratings showed that the actor's fairness and pain would differ depending on the actor's power and status (Expt. 1), which is consistent with the stereotypes above. In particular, the significant effects of the actor's anonymity in the cases of low power and high status (Expts. 2A, 2B) provide further evidence for the proposal that status but not power originates from voluntary support from others.

Animal companionship is gaining popularity in Korea, and interest in dog walking is also increasing as a strategy to maintain the physical and mental health of dogs and dog owners. The purpose of this study was to investigate the perception and satisfaction of dog owners with the neighborhood environments for dog walking and to examine the willingness to pay (WTP) for an off-leash dog park. Of a total of 249 online survey respondents, 47.8% said they take a walk at least once a day and mainly walk around nearby neighborhoods or parks. Respondents showed a high attachment to their dogs and recognized that dog walks help increase physical activity and maintain the health of owners and their dogs. The satisfaction with neighborhood environments, such as attractive views and the connection of walking trails, was low, and there was a high demand for off-leash dog parks. The truncated mean WTP was estimated to be 85,618 Korean Won, and the result of regression analysis and t-test revealed that walking frequency and the satisfaction with dog walking facilities were statistically significant in the WTP. In order to encourage dog walking to promote physical activity and health, more attention needs to be devoted to improving neighborhood environments for dog walking.
