Electronic health records (EHRs) enable us to use and re-use electronic data for various multiple purposes, such as public reporting, quality improvement, and patient outcomes research. Current hospital-acquired pressure injury (HAPI) risk assessment instruments have not been specifically developed for intensive care unit (ICU) patients and showed false positive rates in this specific populations. Previous research studies report a number of risk factors; however, it is still not clear what factors influence ICU HAPI in this population. As part of a larger research study, we performed an exploratory analysis by using a large electronic health record data. The aims of this study were to compare characteristics of patients who developed HAPIs during their ICU stay with those who did not, and to determine whether the two groups were different in the aspects of length of ICU stay, discharge disposition, and discharge destinations. We conducted chi-square test and t-test for group comparison. Association was examined by using bivariate analyses. Pearson correlation coefficients were used to examine correlation between LOS and number of medications. Our findings suggest a number of consistent and potentially modifiable risk factors, such as sedation, feeding tubes, and the number of medications administered. The mortality of the HAPI group was significantly higher than the non-HAPI group in our data. Discharge disposition was significantly different between the groups. 67% of the HAPI group transferred to intermediate or long-term care hospitals whereas 57.7% of the non-HAPI group went home after discharge. Awareness of these risk factors can lead to clinical interventions that can be preventative in the ICU setting.

The purpose of this study was to define the purchase behavior of online luxury fashion brand consumers that soon became new luxury consumption trends. To investigate online luxury fashion brand consumer's purchase behavior, three variables were suggested based on advanced researches. These variables include economic value, item variety and pleasure. Purchasing luxury online was not common but as cross-border online shopping market became popular, consumers began to purchase luxury items through online shopping platforms. Preliminary surveys was conducted on 20~40-year-old consumers who have experience in online shopping for luxurious items. Total 238 questionnaires were used for analysis. By using SPSS, frequency analysis, factor analysis, reliability analysis, correlation analysis, regression analysis, t-test and ANOVA were conducted. The results of the study were as follow; first, consumer's purchase behavior appeared to be influenced by the order of pleasure of shopping, economic value and item variety. Repurchase intention appeared to be affected by the order of economic value, item variety, and pleasure of shopping. Second, online luxury fashion consumers perceived that risk does not affect purchase intention and repurchase intention. Third, as purchase intention increases, repurchase intention also increases. Fourth, shopping value, age and channel risk also indicated meaningful differences. As an early study of luxury fashion brand products purchased directly online, the academic significance can facilitate an overall understanding of consumer behavior such as usage motive, risk perception, behavioral intention.

Objectives: The purpose of this study was to identify the effectiveness of Korean medicine treatment in mild cognitive impairment (MCI) among a group of community dwelling elderly. Methods: Two-hundred and twenty-nine elderly living in a community and diagnosed with MCI were recruited. Participants were evaluated with various instruments such as the Korean version of Mini-Mental State Examination for Dementia Screening (MMSE-DS) and the Korean version of Montreal Cognitive Assessment (MoCA-K). Korean medicine treatment consisted of herbal medicine, acupuncture, and pharmacoacupuncture. The change in cognitive ability was assessed by using the MMSE-DS and the MoCA-K. Data were analyzed by SPSS/WIN 22.0 using the paired t-test, and the ANOVA. Results: The MMSE-DS and the MoCA-K score generally increased after six months of Korean medicine treatment and the differences in both instruments were statistically significant. Additionally, some consecutive participants maintained long-term cognitive improvement. When analyzed specifically by herbal medicine group based on syndrome differentiation and pharmacoacupuncture group, most showed improvement in the MMSE-DS and the MoCA-K but not all data were statistically significant. The satisfaction score was mostly high and most participants were willing to re-participate in the program. Conclusions: Korean medicine treatment may contribute to the improvement and prevention of cognitive decline in the elderly. However, further systematic research based on large scale sample data and standardized protocols is needed to uplift the welfare and mental health of the elderly.

Purpose: This study was done to investigate the degree of self-efficacy, transplant-related knowledge, and other factors affecting compliance with a therapeutic regimen for liver transplant recipients. Methods: Participants were 140 patients who had received a liver transplant at a tertiary hospital in Y City, Gyeongnam Province and made regular hospital visits as outpatients. A self-report questionnaire was used to collect the data and collection was done from December 4, 2017 to January 26, 2018. Data were analyzed using frequencies, percentages, means, and standard deviations, and t-test, ANOVA, Pearson's correlation coefficients. Multiple linear regression was performed using SPSS/WIN 21.0 program. Results: Participants scored $113.29{\pm}20.95$ (out of 150) on self-efficacy, $16.38{\pm}3.62$ (out of 18) on transplant-related knowledge, and $148.30{\pm}31.06$ (out of 200) on compliance with the therapeutic regimen. Analyzed of correlations among participant's self-efficacy, transplant-related knowledge, and compliance with the therapeutic regimen showed a significant positive correlation between self-efficacy and compliance with the therapeutic regimen (r=.64, p=.001), but no significant correlations were found between self-efficacy and transplant-related knowledge (r=-.01, p=.912) or between transplant-related knowledge and compliance with the therapeutic regimen (r=.06, p=.458). Multiple regression analysis showed that factors affecting compliance with the therapeutic regimen were state of re-transplantation (${\beta}=.17$, p=.016) and self-efficacy (${\beta}=.53$, p=.001). Conclusion: There is a need to apply a differentiated nursing intervention program considering the differences in patients' self-efficacy, transplant-related knowledge, and compliance with the therapeutic regimen.

The aim of this study was to determine the therapeutic effects of beauty care on negative mental health, including stress and depression. Nail care, massage care, and makeup were used as programs for beauty therapy. Qualitative research was conducted with six female participants over five-month period. After interviewing the subjects in advance, beauty care treatments were performed every week 4 weeks in the following order: nail care, massage, and makeup. The results are as follows, First, the participants perceived beauty care in the form of 4 concepts: "courtesy in social life," "investment in oneself," "self-satisfaction," and "self-care." Second, the effects of beauty therapy were categorized as "psychological effects," "confidence," "behavioral changes," "evaluation of others," and "positive social effects." Third, each subject showed different psychological effects during the process when the function of the therapy took effect through the beauty care treatment. It was confirmed that confidence levels increased as a result of treatment through the process of becoming re-aware of oneself. Positive statements from the participants included: "I want to go out," "I have become kind and positive to others," "I have become more active in a given task," and "It seems that my work ability is improving." Finally, t-test results for self-esteem, depression, and stress showed there were significant differences in self-esteem and depression. This confirmed that self-esteem increased, and depression decreased after the beauty care treatment.

My essay aims at reading Ginsberg's "Howl" and "Kaddish" with the concept of 'shaman-prophet-poet' to illustrate the dynamic relationship between his poetics and radical politics. Throughout his widely-ranging career, Ginsberg represents himself as a poet-prophet and commands a typical rhetoric of revelation as a way of decentering Cold War orthodoxies. While well aware of the oppressive and pervasive power of the dominant post-war ideologies, he adopts 'madness' to oppose conventional political, social, and religious institutions; by way of entering into the madness of this world and actively engaging himself as a victim, he can finally heal both himself and the world. This dual function of poet characterizes his rhetoric of revelation, but it doesn't appeal to the mainstream of American critical ideology where the post-structural approach to language and subject gives a skeptical look at any account of active human agency and humanistic belief in the possibility of language. In "Howl" and "Kaddish," Ginsburg persuades the reader of the truth of his own vision through the convincing and realistic portraits of his contemporaries as well as his own mother and family. Different from his visionary predecessors such as Emerson and Whitman, Ginsberg knew the difficulty of a negotiation between history and divine vision, and attempted to imbricate his family, friends, and even the larger social and political units within his visionary experience in order to avoid naive idealism, escapism, or solipsism. Furthermore, he deconstructs the Logos of Western prophecy and replaces it with the groundless identity and the nontheistic epistemology of Buddhism, which, in turn, leads to emptying his powerful language of absolutist meaning and prevents his prophecy from becoming re-reified as divine essentialism. Ginsberg's idea of poet and poem revitalizes the skeptical view on language and literary representation of our contemporary critical community which is unwilling to engage the experimental scope of his radical prophecy.

Since the multicast group which is composed of various members is dynamic, members of the group frequently join or leave. So, for a new session, group keys are efficiently updated and distributed. In this paper, we describe very simple and new efficient logical key hierarchy(ELKH) protocol which is based on an one-way function. In the previous schemes, when the group controller distributes new created keys or updated keys to the members the information is usally encryted and then transmited over a multicast channel. But ELKH secretes the multicast message by using the one-way function and XOR operator instead of encrypting it. Hence our main construction improves the computational efficiency required from the group controller and group memebers while doesn't increase size of re-keying message when compared to $EHBT^{[12]}$. Assuming the security of an underlying one-way function, we prove that our scheme satisfies forward secrecy and backward secrecy.

This study analyzed the pressure patterns and local pressure of tall buildings with corner modifications (recessed and chamfered corner) using wind tunnel tests and proper orthogonal decomposition (POD). POD can distinguish pressure patterns by POD mode and more dominant pressure patterns can be found according to the order of POD modes. Results show that both recessed and chamfered corners effectively reduced wind-induced responses. Additionally, unique effects were observed depending on the ratio of corner modification. Tall building models with recessed corners showed fluctuations in the approaching wind flow in the first POD mode and vortex shedding effects in the second POD mode. With large corner modification, energy distribution became small in the first POD mode, which shows that the effect of the first POD mode reduced. Among building models with chamfered corners, vortex shedding effects appeared in the first POD mode, except for the model with the highest ratio of corner modifications. The POD confirmed that both recessed and chamfered corners play a role in reducing vortex shedding effects, and the normalized power spectral density peak value of modes showing vortex shedding was smaller than that of the building model with a square section. Vortex shedding effects were observed on the front corner surfaces resulting from corner modification, as with the side surface. For buildings with recessed corners, the local pressure on corner surfaces was larger than that of side surfaces. Moreover, the average wind pressure was effectively reduced to 88.42% and 92.40% in RE1 on the windward surface and CH1 on the side surface, respectively.

Background: Zinc homeostasis is essential for human health and is regulated by several zinc transporters including ZIP and ZnT. ZIP4 is expressed in the small intestine and is important for zinc absorption from the diet. We investigated in the present study the effects of Panax ginseng (P. ginseng) extract on modulating Zip4 expression and cellular zinc levels in mouse Hepa cells. Methods: Hepa cells were transfected with a luciferase reporter plasmid that contains metal-responsive elements, incubated with P. ginseng extract, and luciferase activity was measured. Using ⁶⁵ZnCl₂, zinc uptake in P. ginseng-treated cells was measured. The expression of Zip4 mRNA and protein in Hepa cells was also investigated. Finally, using a luciferase reporter assay system, the effects of several ginsenosides were monitored. Results: The luciferase activity in cells incubated with P. ginseng extract was significantly higher than that of control cells cultured in normal medium. Hepa cells treated with P. ginseng extract exhibited higher zinc uptake. P. ginseng extract induced Zip4 mRNA expression, which resulted in an enhancement of Zip4 protein expression. Furthermore, some ginsenosides, such as ginsenoside Rc and Re, enhanced luciferase activity driven by intracellular zinc levels. Conclusion: P. ginseng extract induced Zip4 expression at the mRNA and protein level and resulted in higher zinc uptake in Hepa cells. Some ginsenosides facilitated zinc influx. On the basis of these results, we suggest a novel effect of P. ginseng on Zip4-mediated zinc influx, which may provide a new strategy for preventing zinc deficiency.
