Polarimetric study of light scattering from cometary dust particles can provide us opportunity to decipher their characteristics, such as sizes, structures, compositions of dust grains, etc. Herein, we present the results of our polarimetric study of long-period comet, C/2013 US10 (Catalina), in optical and near-infrared wavelengths which appeared at large phase angle (52.7 degrees) around the mid-December, 2015. We performed polarimetric and spectroscopic observations with HONIR, attached to the 1.5-m telescope at Higashi-Hiroshima Observatory, on UT 2015 December 17-18 and also obtained optical imaging data sets by the Ishigakijima Astronomical Observatory (IAO) and Okayama Astrophysical Observatory (OAO) taken between 2014-2015. By measuring the intensities of gas emission lines with respect to dust continuum and considering transmittance of each filter, we estimated that the percentages of gas contamination are approximately 10 percents in $R_C$-band and 3 percents in $I_C$-band. With these results, we derive the degree of linear polarization scattered solely from dust components in the coma. At this presentation, we will compare the phase-angle dependence of the degree of linear polarization with those of previous archive data in a wide coverage of wavelengths from $R_C$-band to $K_S$-band. Finally, we are supposed to discuss the spatial variations in polarization within the coma.

Family environment plays a significant role in adolescent development. Multicultural adolescents in Korea are brought up in a distinctive family environment, where they get to experience two different cultures within their families. Thus, it is important to examine how internal characteristics of the family environment in multicultural families and interactions between family members influence adolescents. The aim of the current study was to examine structural relationships among Southeast Asian mothers' and Korean fathers' bilingual socialization, adolescents' attitude toward mothers' native culture, and mother-adolescent relationship satisfaction. Specifically, the following two questions were addressed in this study: 1) Does bilingual socialization of each parent affect adolescents' attitude toward mothers' native culture? 2) Does children's attitude toward mothers' native culture affect mother-adolescent relationship satisfaction? To answer these questions, the survey data from the '2012 Nationwide Survey of Multicultural Families' was analysed, using SEM. The sample consisted of 318 multicultural adolescents (aged 9-17) living with Korean fathers and immigrant mothers from Southeast Asia. The main findings were as follows. First, Korean fathers' bilingual socialization had a positive effect on immigrant mothers' bilingual socialization. The path from Korean fathers' bilingual socialization to adolescents' attitude toward mothers' native culture was significantly mediated by immigrant mothers' bilingual socialization. Second, adolescents' attitude toward mothers' native culture had a positive effect on mother-adolescent relationship satisfaction. Results suggest that Korean fathers' bilingual socialization is an important factor for bilingual socialization of multicultural adolescents. It is also worth noting that each parent's bilingual socialization helps multicultural adolescents to form a positive identity as a member of multicultural families.

In recent years, leisure time has received increasing attention in Korean society. Despite the growing interest, however, there are very few studies that explored shared leisure time, especially among married couples. In this light, the present study examined variations in shared leisure time by demographic characteristics and associations between shared leisure time and quality of marital relationship. We used the third wave of the national data KLoWF (Korean Longitudinal Survey of Women and Families, 9,997 19-64 years old women). The study sample included 5,965 married women with no prior history of divorce. Results showed that Korean wives reported very little shared leisure time with their husbands. Given that the mean of the shared leisure time reported by employed women was significantly lower than that of the un-employed, we speculated that the time constraint may be one of the major barriers to having leisure time with one's spouse among Korean married couples. Married women in their 30's had the most frequent couple leisure time. The younger wives in their 20s had more cultural leisure time with their husbands, but sharing outdoor leisure time was not related to their age. The higher level of education for women was associated with greater shared active leisure time. However, visiting a husband's family often took place regardless of the wives' education level. After controlling for age, years of education, job status and annual family income, shared active leisure time (i.e., cultural activity and exercise) was positively related to marital satisfaction. Visiting one's own family, however, was not considered a leisure activity for Korean wives. Rather, frequent family visits were related to lower marital satisfaction. Findings shed light on how leisure life of married women with spouses are intertwined with not only their socioeconomic status and but also marital relationship in culturally unique ways.

The purpose of this study was to investigate the difference in self competence between children from multicultural families and children from Korean families, and to study how interparental conflict and peer relationship influence the self competence of children. The subjects of the present study were 138 children of multicultural families and 254 children of Korean families in the 3rd or 4th grade in Seoul, Daegu, Gyeong-gi province, and Gyeong-buk province. The instruments of measurement were the Children's Perception of Interparental Conflict, Friendship and the Perceived Competence Scale for Children. Date were analyzed by independent samples T-test, MANCOVA, ANCOVA and multiple regression using the SPSS program. The results showed there was significant difference in the self competence of children between those from multicultural families and those from Korean families, but there was no significant difference when income was controlled. Second, for children of multicultural families, gender, income, and the intensity of interparental conflict had significant influence on self competence while gender, aid, conflict, and disclosure of negative affect in friendship, and being a peacemaker in interparental conflict influenced self competence significantly in the case of children of Korean families.

Fashion luxury products, which used to mean high-quality, handcrafted not-so-trendy items, are nowadays regarded as expensive fashion merchandise produced under the name of imported well-known brands. People cunsuming fashion luxury products distinguish themselves from other people according to the luxury fashion brands they are using, and as a result, advertisements of fashion luxury products are taken as a kind of international language. The purpose of this study is to point out the socio-cultural meanings of consuming fashion luxury products, by analyzing images shown in advertisements of fashion luxury products focusing on women's images. To do so, this study is based on general theoretical background on fashion, consumer culture advertising and analysis advertisements of fashion luxury products shown in fashion magazines in recent three years. The result of this study is as follows; The images of the advertisements of fashion luxury products could be categorized as (1) elegance, (2) kitsch and (3) fetish. Elegance is a taste of high society, aesthetically chic and feminine. Fashion luxury products, which are merchandise of extravagance, dignity, refinement, feminity and harmony, exhibit high-quality grace through their advertisements. Kitsch represents the vulgar and popular images of trivial commodities of industrial society. In the advertisement of fashion luxury product, it is shown as inappropriateness, excessiveness, stereotyped pleasantness, exaggeration an playful satisfaction. Finally, fetish images represent erotic or perverted sexuality, based on psychoanalytic fetishism which objects are regarded s substitute of sexual orgasm. The advertisements of fashion luxury product are characterized as (1) popularization of luxury, (2) objectification of sex and body, and (3) re-aestetification of anti-aesthetics. The asvertisements of fashion luxury products are actually targeted to the middle class with successful career women's images. They objectify female bodies through fetishistic images. Also, the deviant subcultural style, represented a new kind of cultural capital, is now reproduced as a new commodity aesthetics.

Charlotte $Bront{\ddot{e}}^{\prime}s$ novel Jane Eyre has long been doted on as one of the canonized texts of British literature since its publication. Seemingly, this romantic novel has nothing to do with plantation based on slave trade. However, paying a keen attention to the fact that Jane's enormous inheritance results from wine plantation at a colony, this essay re-interprets Bertha's drinking and madness as evidence of imperialism. For the porter/jin Bertha and Grace Poole enjoy might have some suspicious connection with wine, the very root of Jane's great expectations. Jean Ryes' Wide Sargasso Sea, writing Jane Eyre back, records Bertha as "a white resident of the West Indies, a colonizer of European descent" (326). However, Jane Eyre, in my interpretation, describes Bertha pretty much as a black Creole. At any rate, the view that the white West Indians are tainted by miscegenation proves contemporary racism and is reflected in the text through Bertha and her mother's intemperate drinking and madness. Drinking and madness are stigmatized as the evidence of the so-called "bad blood"; embodying the stereotypes of drinking, madness, and sexual corruption, Creoles, the very inescapable product of imperialism, provide a convenient excuse for justifying imperialism for purity, civilization, and moral cleanness. In this way, Jane Eyre needs to be re-interpreted politically and historically in the context of colonialism. British imperialism pursues a tremendous amount of profits through grape plantation and wine trades; however, it cleverly leaves in the colony the associated images such as intemperate drinking and madness. Bertha, transferred from Jamaica to Britain, takes in these negative images of "savageness." Transcending the narrow confines of feminist criticism obsessed with doubling between Bertha and Jane, this essay, accordingly, reads Bertha the prisoner in the attic as the captive for perpetuating imperialism. This reading hinges upon interpreting Rochester and St John as colonizers bearing the so-called "white men's burden" to cultivate and civilize savages much like crops such as grapes and sugarcane in the colonial plantation.

Objectives: The aim of the present study was to assess the frequency of use, and preferences regarding information and communication technologies (ICTs) among Ecuadorian patients with chronic kidney disease (CKD) undergoing hemodialysis. Methods: We conducted an anonymous cross-sectional survey-based study from January 2016 to April 2017, involving 393 patients with end-stage renal disease from 9 hemodialysis centers, in which they rated their use and preferences of various ICTs through a modified version of the Michigan Questionnaire. The questionnaire collected information regarding demographics, patients' interest in obtaining health-related information through ICTs, and interest in using ICTs as a potential way to communicate with their healthcare providers. A chi-square test for association and adjusted regression analyses were performed. Results: Among all patients who participated, 64.3% reported owning a cellphone, with less than a third reporting active Internet connection. The most used ICT for obtaining information about CKD and/or hemodialysis was web-based Internet, followed by YouTube. SMS was rated the highest to receive and seek health-related information, followed by Facebook. Younger age and higher levels of education were associated with a higher overall usage of ICTs. Finally, more than half of the patients reported interest in using WhatsApp for communicating with their healthcare providers. Conclusions: Understanding the preferences of ICTs among patients with CKD undergoing hemodialysis could help to improve their outcomes through the potential uses and benefits of ICTs. Further research is needed to assess their role in improving the care of patients with chronic diseases.

PURPOSE. The aim of this study was to evaluate the effect of occlusal adjustments on the surface roughness of yttria-tetragonal zirconia polycrystal (Y-TZP) and wear of opposing artificial enamel. MATERIALS AND METHODS. Twenty-five Y-TZP slabs from each brand (Lava, 3M and Bruxzir, Glidewell Laboratories) with different surface conditions (Control polished - CPZ; Polished/ground - GRZ; Polished/ground/repolished - RPZ; Glazed - GZ; Porcelain-veneered - PVZ; n=5) were abraded (500,000 cycles, 80 N) against artificial enamel (6 mm diameter steatite). Y-TZP roughness (in ${\mu}m$) before and after chewing simulation (CS) and antagonist steatite volume loss (in $mm^3$) were evaluated using a contact surface profilometer. Y-TZP roughness was analyzed by three-way analysis of variance (ANOVA) and steatite wear by two-way ANOVA and Tukey Honest Difference (HSD) (P=.05). RESULTS. There was no effect of Y-TZP brand on surface roughness (P=.216) and steatite loss (P=.064). A significant interaction effect (P<.001) between surface condition and CS on Y-TZP roughness was observed. GZ specimens showed higher roughness after CS (before CS - $3.7{\pm}1.8{\mu}m$; after CS - $13.54{\pm}3.11{\mu}m$), with partial removal of the glaze layer. Indenters abraded against CPZ ($0.09{\pm}0.03mm^3$) were worn more than those abraded against PVZ ($0.02{\pm}0.01mm^3$) and GZ ($0.02{\pm}0.01mm^3$). Higher wear caused by direct abrasion against zirconia was confirmed by SEM. CONCLUSION. Polishing with an intraoral polishing system did not reduce the roughness of zirconia. Wear of the opposing artificial enamel was affected by the material on the surface rather than the finishing technique applied, indicating that polished zirconia is more deleterious to artificial enamel than are glazed and porcelain-veneered restorations.

This study explores experiences of college nursing students during the COVID-19 pandemic. The participants were 10 college nursing students (junior and senior years) enrolled in a university in K city. Data were collected through in-depth interviews from May 1 to June 30, 2020. The phenomenological methodology proposed by Colaizzi was applied for data analysis. We identified a total of 6 theme clusters: increased fear of an infection, feeling isolated due to the changed way of life, feeling perplexed about unexpected circumstances, inability to adapt to the sudden change in classroom instruction, feeling burdened about clinical practice, and confronting the reality as a preliminary nurse. The analyzed data revealed that subjects had numerous experiences about COVID-19. We believe there were necessity and significance to conduct this study during the ongoing COVID-19 pandemic. This analysis can serve as a useful resource for discussing issues related to nursing education in the post COVID-19 era.
