Previous studies have suggested that rice bran oil (RBO), an edible oil from the byproducts of rice milling, has anti-inflammatory effects in inflammation inducing macrophages, known as M1 subsets. Yet the effects of RBO on the counterpart M2 subsets, the "healing" macrophages, were poorly investigated to date. In this regard, recent studies on the molecular/cellular anti-inflammatory mechanisms of dietary components have demonstrated that mitochondrial respiration contributes to macrophage functioning. Therefore, the current study examined whether RBO regulates cytokine secretion by modulating mitochondrial metabolism in wound healing M2 subsets. Palm oil (PO), enriched with medium-chain fatty acids, served as a positive control. C57BL/6 mice were fed a diet containing either corn oil (CO), PO or RBO for 4 weeks, followed by purification of bone marrow-derived macrophages (BMDM) from their tibias and femurs. Cells were further polarized to M2-BMDM, and the expression of M2 marker (CD206) on cellular surfaces were not affected by dietary intervention. In addition, the secretion of anti-inflammatory cytokine (IL-10) in the culture supernatant was not affected by dietary lipids. Oxygen consumption rate, the indicator of mitochondrial respiration in M2-BMDM was not regulated by RBO intervention and PO treatment. Taken together, this study imply that RBO did not intervene both the regulation of inflammatory responses and mitochondrial respiration in M2 macrophages.

This essay aims to examine chick lit written within the Asian American context. For the most part, the chick lit genre has been typically regarded as a site to study contemporary white women's experiences and to debate the genres' credentials as feminist literature. Though some may disagree, there is general consensus that chick lit has fallen out of vogue after reaching its peak in the first decade of the new millenium.; nevertheless, it is being revisited by readers and critics alike as it has recently re-emerged as a location upon which to examine how race and gender inform notions of national belonging and female subject formation in the twenty-first century. To this end, this essay reads Kim Wong Keltner's The Dim Sum of All Things (2004). Keltner's protagonist Lindsey Owyang is yet another twentysomething "chick" looking for love, self, independence, and success in the huge megalopolis of San Francisco. What sets Lindsey apart from the chick prototype is that she is a third-generation ABC (American-born Chinese) and issues relevant to Asian America frequently make their way into Lindsey's narrative. Though it is generally considered as standing a "few notches above the standard chick-lit fare" (Stover n. pag), I would argue that meaningful reflections on many of the major pillars of Asian American literature, history, and cultural politics are glossed over in favor of cursory musings about the daily vicissitudes of Lindsey's life. This essay thus takes to task Ferriss's claim that a "serious" consideration of chick lit "brings into focus many of the issues facing contemporary women and contemporary culture - issues of identity, of race and class, of femininity and feminism, of consumerism and self-image" (2). I contend that a close examination of Keltner's The Dim Sum of All Things discloses that the chick lit format undermines a "serious consideration" of Asian American issues by presenting in particular a highly problematic representation of race and of Asian American femininity.

As the un-tact and on-tact consumption culture has proliferated due to the impact of COVID-19, 'live commerce', a form of shopping while communicating with customers through real-time streaming broadcasting, is emerging in the commerce and distribution industry. Live commerce provides an environment where customers can get the convenience of online shopping and enjoy un-tact shopping more realistically while communicating with the broadcaster in real time, as if purchasing directly from an offline store. Therefore, purchases using live commerce are expected to increase further. In this study, based on the characteristics of live commerce, the main factors influencing the increase in purchase intention through live commerce were derived and their influences were verified. In particular, this study examined these factors in multiple dimensions with focusing on strong interactivity, realistic presence, and providing detailed reviews with high credibility for products as the features of live commerce. This research collected sample data from actual users of live commerce and empirically analyzed the significance of the factors influencing the purchase increase of live commerce, thereby providing implications for knowledge management in a newly changed commerce environment in the un-tact era.

Background: We conducted a cross-sectional study of residents within and outside Fukushima Prefecture to clarify their perceptions of the need for smartphone applications (apps) for explaining exposure doses. The results will lead to more effective methods for identifying target groups for future app development by researchers and municipalities, which will promote residents' understanding of radiological situations. Materials and Methods: In November 2019, 400 people in Fukushima Prefecture and 400 people outside were surveyed via a web-based questionnaire. In addition to basic characteristics, survey items included concerns about radiation levels and intention to use a smartphone app to keep track of exposure. The analysis was conducted by stratifying responses in each region and then cross-tabulating responses to concerns about radiation levels and intention to use an app by demographic variables. The intention to use an app was analyzed by binomial logistic regression analysis. Text-mining analyses were conducted in KH Coder software. Results and Discussion: Outside Fukushima Prefecture, concerns about the medical exposure of women to radiation exceeded 30%. Within the prefecture, the medical exposure of women, purchasing food products, and consumption of own-grown food were the main concerns. Within the prefecture, having children under the age of 18, the experience of measurement, and having experience of evacuation were significantly related to the intention to use an app. Conclusion: Regional and individual differences were evident. Since respondents differ, it is necessary to develop and promote app use in accordance with their needs and with phases of reconstruction. We expect that a suitable app will not only collect data but also connect local service providers and residents, while protecting personal information.

Global warming has accelerated in recent decades due to the continuous consumption of petroleum-based fuels. Cyanobacteria-derived biofuels are a promising carbon-neutral alternative to fossil fuels that may help achieve a cleaner environment. Here, we propose an effective strategy based on the large-scale cultivation of a newly isolated cyanobacterial strain to produce phycobiliprotein and biodiesel, thus demonstrating the potential commercial applicability of the isolated microalgal strain. A native cyanobacterium was isolated from Goryeong, Korea, and identified as Pseudanabaena mucicola GO0704 through 16s RNA analysis. The potential exploitation of P. mucicola GO0704 was explored by analyzing several parameters for mixotrophic culture, and optimal growth was achieved through the addition of sodium acetate (1 g/l) to the BG-11 medium. Next, the cultures were scaled up to a stirred-tank bioreactor in mixotrophic conditions to maximize the productivity of biomass and metabolites. The biomass, phycobiliprotein, and fatty acids concentrations in sodium acetate-treated cells were enhanced, and the highest biodiesel productivity (8.1 mg/l/d) was achieved at 96 h. Finally, the properties of the fuel derived from P. mucicola GO0704 were estimated with converted biodiesels according to the composition of fatty acids. Most of the characteristics of the final product, except for the cloud point, were compliant with international biodiesel standards [ASTM 6761 (US) and EN 14214 (Europe)].

The purpose of this study was to analyze the different consumption patterns of fashion products according to the demographic characteristics and religious variables of Muslim women in Indonesia. The research method consisted of a questionnaire, which surveyed Muslim women in Indonesia, whose ages ranged from teens to 40s. The final questionnaire made use of 301 responses, and the analysis methods included 𝛘²-testing, factor analysis, and ANOVA. The results of this survey are as follows: For differences in average monthly clothing purchase costs, there were significant differences according to age, monthly income, final education, and whether or not the respondent wore a hijab, but there was also significant difference according to marital status and religious faithfulness. Muslim women's clothing purchasing factors were practicality, visibility, fit-to-wear, and design. In terms of the differences in factors which were considered when purchasing clothing, they depended on whether or not the respondent was married, practicality and visibility according to age, visibility according to final education, and religious faithfulness. There were significant differences in practicality and visibility, but not according to monthly income. When accounting for the differences in the places where Muslim women bought fashion products, there were significant differences according to marital status and age. In terms of the differences in reasons for choosing a place of purchase, there were significant differences according to age, monthly income, final education, and the degree of hijab wearing.

This study analyzes the use and meaning of consumer personality implication words in the review text of the Used Transaction Application . From of May 2021, the data were collected for the past six months by our Web crawler in Seoul and Gyeonggi Province, and a total of 1368 cases were collected first by random sampling, and finally 570 cases were preprocessed. The results are as follows. First, 48.2% of review texts were related to the personality of consumers even though it was a commercial platform of products. Second, the review text is mainly positive, which formed a text network structure based on the keyword 'gratitude'. Third, the review text, which implies consumer character, was divided into two groups: 'extrovert personality' and 'introvert personality' of consumers. And the individuality of the two groups worked together on the platform. In conclusion, we would like to suggest that consumer personality plays an important role in the platform transaction process, that consumer personality will play a role in the services of the platform in the future, and that consumer personality should be studied from various perspectives.

Purpose : Although quantitative research on alcohol consumption among nursing students is important, qualitative research is needed to determine the subjective views of individual students, such as their feelings and thoughts, and ensure the implementation of a targeted alcohol intervention program. Q-methodology is a systematic approach that examines the subjective perspectives of individuals, including their views, beliefs, and attitudes, enabling understanding of the types and characteristics according to the individual's subjectivity structure. This study examined the subjective perceptions of drinking among freshmen in nursing college using Q methodology. Methods : Q-sorting was conducted, collecting 38 P samples and 40 statements. The data were analyzed using the PC QUANL program. The principal component factor analysis method was used for Q-factor analysis. Results : The results identified four types of drinking perceptions among freshmen in nursing college. Type 1 was "safety and health pursuit," type 2 was "friendship pursuit," type 3 was "'norm-oriented," and type 4 was "sound manners." When looking at the subjective perceptions of drinking among freshmen in nursing college, there was a common opinion that drinking should not be forced and that it is an individual choice. However, the difference in views (positive and negative) of drinking shows the need for customized educational programs and interventions suitable for each type. Conclusion : Nursing freshmen should be prepared to play an important role in health care as an educational role and model in preventing damage from drinking and maintaining health promotion throughout their life by habituating proper drinking behavior during college life. In addition, it is necessary to develop a plan to increase positive awareness of drinking among nursing students through various strategic programs that can participate in sobriety prevention programs within the university.

This study analyzed the flow inside floating seedling equipment for Scapharca subcrenata. Due to the aging society of fishing villages, it is impossible to continuously input the labor force. Therefore, it is necessary to improve efficiency. Scapharca subcrenata has high per capita consumption. It serves as an important aquatic food resource. Scapharca subcrenata culture tends to be highly dependent on the natural environment. Production of Scapharca subcrenata is difficult to predict with low stability. In the past, manpower directly installed bamboo nets in mudflats. The seedling equipment devised in this study is a floating type and can be freely moved on the sea according to the prediction of Scapharca subcrenata generation. The flow around the floating seedling equipment was analyzed by numerical analysis. The physical phenomena of the flow around the net inside the floating seedling equipment were visualized. As a result, the space between the floating seedling equipment and the bottom net and the space between the net groups showed a lower flow rate than the inlet flow rate. It is expected that the low flow rate of the floating seedling equipment will have a positive effect on the attachment of Scapharca subcrenata.

This study aims to focus on the text analysis, production methods of text, and reproduction of production methods, based on a film (2010) taken by mobile devices. As a digital film in which the objects and images have no characteristics of index, this work has the post-cinematic attributes in the aspect of consumers' recipience. This thesis paid attention to the interactions between essential change and production/consumption throughout the whole film culture in the receptive aspect. Just as the main character is a mediator-shaman in the film, this film works as a mediating position of cinematic possibility. In this film, there are different kinds of mediation such as mediation of shaman inside the text, mediation of film in the relationship between text and consumers, and consumers' instrumental desire for others'tool outside the text. Outside the text, this relevant film stimulates the imitation desire of consumer subjects as others. In other words, this is connected to the desire of consumers who aim to create a digital film through mobile devices as an author. This is connected to Simondon's thinking in which such technical objects not only generate new relationships, but also become a revolutionary seed that newly collectivizes human society.
