Purpose: The purpose of the study was to develop and evaluate the effect of a metabolic syndrome prevention program using mobile application for university students. Methods: A pretest-posttest design with content analysis as a triangulation method was used. The participants were 49 university students. Data were analyzed using descriptive statistics, $x^2$-test, t-test and Fisher's exact test with the SPSS WIN 18.0 program. Results: The application consisted of six main menus as follows: 'basic education', 'nutrition education', 'exercise education', 'meal diary', 'exercise checkup', and 'tips'. The experimental group had higher recognition about metabolic syndrome prevention than the control group (F=7.919, p=.007). Understanding of metabolic syndrome among participants was mostly related to chronic diseases such as obesity, hypertension and diabetes in relation to the importance of eating habits and exercising. Conclusion: The results indicate that metabolic syndrome prevention education using mobile application is necessary and would be useful for university students.

Objectives The ratio of second to fourth digit length (2D : 4D) could be a potential epigenetic marker of sexual dimorphism reflecting prenatal testosterone exposure. Testosterone is known to affect the development of the brain through an epigenetic mechanism. The purpose of this study was to investigate the effects of exposure to fetal testosterone on the metabolic syndrome based on 2D : 4D of schizophrenia patients and the relationship with the age of onset of schizophrenia. Methods A total of 214 schizophrenia patients participated in this study. The participant's physical and blood tests were performed according to the American National Cholesterol Education Program's Third Amendment of the Metabolic Syndrome Diagnostic Criteria, and the 2D : 4D was measured by the method designed by McFadden. Data were statistically analyzed by t-test, Pearson's correlation analysis and multiple regression model analysis. Results 2D : 4D was significantly higher in female than male in both hands, and there was a statistically significant negative correlation between 2D : 4D and the age of onset of schizophrenia in male. However, 2D : 4D did not show statistically significant correlation with metabolic factors. Conclusions Fetal testosterone suggests the possibility of affecting the age of onset of schizophrenia through the epigenetic mechanism, but there is no clear relationship with metabolic factors.

Purpose: The purpose of this study was to develop a feeding protocol for premature infants and to evaluate the effects of protocol. Methods: The feeding protocol was developed through a literature review and discussions of an expert group. The developed feeding protocol was tested with 85 preterm infants in one neonatal intensive care unit in B city. A non-equivalent control group non-synchronized design was used. Data were collected from January 1 to April 30, 2013 for the control group and from June 1 to September 30, 2013 for the experimental group. The experimental group (n=38) received the feeding protocol, whereas the control group (n=47) had routine feeding care. Collected data were analyzed by t-test and -test using SPSS/WIN version 18.0. Results: First feeding time (t=2.22, p=.029) and full enteral feeding time (t=2.28, p=.026) were significantly decreased in the experimental group compared to the control group. There was no difference in incidence of complications (p>.05). Also no significant differences in weight reduction rate between the two groups were observed at the 7th postnatal day (t=-1.23, p=.222). Conclusion: The results indicate that the feeding protocol for preterm infants is effective in decreasing first feeding time and full enteral feeding time.

With environmental pollution becoming a serious problem, recently there has been increased interest in the environment and health. In addition, the development of materials for environmentally friendly and functional clothing has increased. Environmentally friendly products that use bark fibers of the mulberry(dak) tree are expressed in terms of dak fiber and Hanji yarn. This research analyzed consumer's perceived images of Hanji and Hanji yarn infant clothing. The research results are as follows. Based on analyzing images of Hanji and Hanji yarn, Hanji was categorized into four images that can be described as natural, pure, decorative, and functional, and Hanji yarn infant clothing was categorized into three images that can be described as natural, decorative, and functional. Based on the analysis of well-being elements in subjects' lifestyles, the following four inclinations were found: environmental friendliness, pursuit of novelty, life care, and environmental protection. On this basis, the subjects were categorized into three groups: the trend-pursuing group, the life-care group, and the social responsibility group. Subjects' perceived images of Hanji and Hanji yarn infant clothing were investigated, and these products were found to have a strong image of being Korean, traditional, and natural, while being weakly perceived as comfortable, functional, and practical. Analyzing the correlation between images of Hanji and Hanji yarn infant clothing and lifestyle groups revealed that these products were not perceived differently according to group. This study showed that Hanji and Hanji yarn are terms that are commonly associated with positive clothing material. However, both Hanji and Hanji yarn are perceived negatively in terms of functional image, which is an important factor in clothing material. In addition, even among consumers who pursue a lifestyle based on well-being, the functional image of Hanji yarn was not perceived highly. Hence, it is necessary to further examine the effect of terms such as Hanji and Hanji yarn on consumer choices. Therefore, caution is considered needed when using such terms in the marketing of related products.

Although the human body is a biological subject with definite and distinctive physical features, its actualization and perception differs among societies. The aesthetics of the human body are based on diverse cultural perceptions that must be considered prior to design development. This study establishes the foundations of newly adopted concepts of beauty that are presumed to have been established in the first half of the twentieth century that continue to affect our mindset even now. The research includes human figures in the articles of women's magazines and cosmetic advertisements in the early $20^{th}$ century. The results are as follows: First, the change of perception in the human body: Instead of being a subject of preservation, the body has become a subject of sculpture with emphasis on health in the 1920's and on beauty in the 1930's. The recognition of the importance of the body has created intensive attention on physical training and an increased sense of hygiene. The body exposed to the public perceives itself through the eyes of others that alter one's own perception of oneself as well as become a target of evaluation. There is an additional emphasis on the exotic eroticism of a passive subordinate. Western culture became the standard for modernization along with the dissociation of traditional standards and values. Through the effect of education and western thinking, the awareness of women's rights and self-appreciation was developed. Second, ideal beauty can be summarized as follows: Unprocessed natural beauty was extolled as ideal in the 1920's, but the 1930's, it highlighted big eyes and an aquiline nose that are the characteristics of western women. Taking care of one's appearance was recognized as an important value for every social class. Cosmetics and skin care treatments promised soft and white skin. In contrast to western cosmetics, dark and shiny hair was highly favored. Exercising and traveling, differing seasonal and regional skin treatments were also widely accepted. In its initial stages, the research had originally assumed that the beginning of the twentieth century would be a time in which traditional concepts of beauty and new, westernized aesthetics coexisted. However, as the research progressed, it was clear that the idea of beauty had already adopted occidental ideals by that time. Thus, it seems necessary to continue the study on the shifting paradigms of beauty that must have occurred in the nineteenth and late twentieth century.

Design is a knowledge service industry that is undervalued in Korea despite its large impact on the development of high - tech industries such as national industrial policy and the fourth industrial revolution. In the design industry, the strategic outsourcing system collapses. This phenomenon is not confined to the domestic market, and the design service companies of design-developed countries such as Europe and the US are also struggling with the classic. Accordingly, some implications were found through the case study of domestic design projects, including overseas, that private companies are more concerned with design cost reduction and cost structure to secure liquidity rather than improving design quality level and pursuing innovation through design outsourcing. It is big. As design is a core competency of a company, internalizing core design tasks, and as products and services become platforms, regional design countermeasures have been reduced, which has led to a decline in the cost standard for large companies' design service outsourcing. In design service industry, design outsourcing is performed at the request of the client, and the service value of the outsourcing is received. In the early 2000s, the importance of design management led global consulting companies to pursue M & A rather than cooperate with design service companies, and Samsung Electronics and other large corporations acquired a large number of excellent design personnel and developed their own design management research institute. This study investigated the design service outsourcing cases of public and private companies (large corporations, midsize companies) widely in relation to the design service price criterion, and grasped the indicators of the actual size and level of the design industry. I will make suggestions about the value and direction of the global design industry through interviews with experts and literature on the changes and influences of these cost criteria.

With the development of Internet and mobile technology and the spread of social media, a large amount of information is being generated and distributed online. Some of them are useful information for the public, but others are misleading information. The misleading information, so-called 'fake news', has been causing great harm to our society in recent years. Since the global spread of COVID-19 in 2020, much of fake news has been distributed online. Unlike other fake news, fake news related to COVID-19 can threaten people's health and even their lives. Therefore, intelligent technology that automatically detects and prevents fake news related to COVID-19 is a meaningful research topic to improve social health. Fake news related to COVID-19 has spread rapidly through social media, however, there have been few studies in Korea that proposed intelligent fake news detection using the information about how the fake news spreads through social media. Under this background, we propose a novel model that uses Graph2vec, one of the graph embedding methods, to effectively detect fake news related to COVID-19. The mainstream approaches of fake news detection have focused on news content, i.e., characteristics of the text, but the proposed model in this study can exploit information transmission relationships in social engagement networks when detecting fake news related to COVID-19. Experiments using a real-world data set have shown that our proposed model outperforms traditional models from the perspectives of prediction accuracy.

Insecticidal and antifeeding activities of 29 commercialized eco-friendly organic products for managing plant diseases and insect pests against Plutella xylostella larvae, Spodoptera exigua larvae, Frankliniella occidentalis adults, and Myzus persicae adults were tested using spraying and leaf dipping bioassays under laboratory conditions. Products containing 60% Sophora extract (EOIS) and mixtures (EOISm) with Sophora extract, Stemona japonica extract, Melia azedarach extract, and Nepeta cataria extract as well as mixtures (EOISc) with Sophora extract, Chenopodium ambrosioides extract, and Melia azedarach extract as active ingredients showed strong insecticidal activity at recommended concentration against P. xylostella larvae. At half concentration, their insecticidal activities were decreased under 50%. The EOIS gave good insecticidal activity against S. exigua larvae and also showed 85% and 95% insecticidal activity at 24 and 48 hours after treatment to F. occidentalis adults, respectively. For M. persicae adults, EOISm and mixtures (EOIR) containing rape seed extract, neem extract, and castar oil produced 93% and 68% insecticidal activity, but their activities did not be increased at double concentration. EOISm only showed 100% contact toxicity against M. persicae adults exposed to dipping leaves. Interestingly, the insecticidal activity of EOIR and EOICi (citronella oil and derris extract) against M. persicae adults was increased with exposed time and concentration. In addition, EOICe (cedar oil), EOIS, EOISm, EOISc, EOIM (microorganism), EOIR, EOIPe (plant extract), and EOIT (tea tree extract) gave strong antifeeding activity against S. exigua and P. xylostella larvae. EOIB, EOIBs, EOIM, EOICi, and EOIMc showed above 70% antifeeding activity to the lepidopteran larvae. These results indicate that mixtures containing 2 to 3 plant extracts with Sophora extract show good activities against insect pests, although the difference of insecticidal and antifeeding activities was produced depending on both a tested insect species and an active ingredient or concentration.
