Understanding the attitudes toward sunless tanning product use: implication of tanning product consumption

Jeong‑Ju Yoo,Hyeon Jeong Cho 한국의류학회 2018 Fashion and Textiles Vol.5 No.1

The goal of this study is to test the antecedents of overall attitudes toward sunless tanning product use. The data collected from 302 US female college students with an average age of 20.11 were included in the analysis. A structural equation modeling was performed to test the hypothesized relationships. The results revealed that body surveillance and social ostracism influenced the individuals’ cutaneous body image dissatisfaction, which also influenced perceived attractiveness and fitness of tanned appearance. Perceived tanning attractiveness and perceived tanning physical fitness positively influences attitudes toward tanning product use. It is evident that seeing one’s own body through the lens of others is at the root of positive attitudes toward sunless tanning products. Positive attitudinal changes toward sunless tanning products can be successfully established emphasizing sunless tanning products as fashion consumption. The findings in this study have important relevance, in that tanning products can be marketed as cosmetic appearance-enhancement products for people to look attractive, toned, and fit.

In this study, we analyzed the characteristics of atmospheric stability to investigate local environment change at an atomic power plant in Gori region. The used data was obtained from field observation of major meteorological variables such as wind direction and speed, air temperature, relative humidity, and solar radiation using AWS (Automatic Weather System) in Gori region from February to September in 2003. As a result, when strong northerly winds (more than 4~6 m/s) and weak northwesterly winds (2~3m/s) blow, atmospheric stability was neutral and stable from winter to spring, respectively. Atmospheric stability (neutral) in summer was similar to that in two other seasons (winter and spring), but it was stable for weak southwesterly winds (2~3 m/s). Finally, atmospheric stability was neutral for strong winds (over 4~6 m/s) in fall without respect to wind direction, while that was stable for very weak winds (less than 2 m/s).

Purpose: This study was conducted to investigate the extent of diffusion of Intravenous infusion nursing practice guideline among nurses in advanced general hospitals and general hospitals in Korea. Methods: The subjects were 234 nurses who practice the intravenous infusion in 24 advanced general hospitals and general hospitals. Data were collected between October 5 and November 2, 2015 by mail (return rates: 97.5 %). Data were analyzed using descriptive statistics, t-test, and ANOVA with SPSS/ WIN 21. Results: The average guideline diffusion score and levels of diffusion was 3.39±0.58 (level of “use sometimes”). 44 recommendations (46%) were in level of “use always” and 50 recommendations (53%) were in “use sometimes”. Extent of diffusion were significantly different according to present status (F=2.81, p=.040) and education (F=4.35, p=.014). The facilitating factors to use the guideline were education by department of nursing service, convenient composition of guideline and barrier factors were “no time to use the guideline”, “don’t know the guideline” and “there is no guideline at ward”. Conclusion: Extent of diffusion of Intravenous infusion nursing practice guideline among nurses was moderate level. The strategies for promoting the implementation of guideline in clinical practice is needed. Further study of outcome evaluation of guideline implementation will be needed.

Acute kidney injury in patients with acute-on-chronic liver failure: clinical significance and management

( Jeong-ju Yoo ),( Moo Yong Park ),( Sang Gyune Kim ) 대한신장학회 2023 Kidney Research and Clinical Practice Vol.42 No.3

Acute-on-chronic-liver failure (ACLF) refers to a phenomenon in which patients with chronic liver disease develop multiple organ failure due to acute exacerbation of underlying liver disease. More than 10 definitions of ACLF are extant around the world, and there is lack of consensus on whether extrahepatic organ failure is a main component or a consequence of ACLF. Asian and European consortiums have their own definitions of ACLF. The Asian Pacific Association for the Study of the Liver ACLF Research Consortium does not consider kidney failure as a diagnostic criterion for ACLF. Meanwhile, the European Association for the Study of the Liver Chronic Liver Failure and the North American Consortium for the Study of End-stage Liver Disease do consider kidney failure as an important factor in diagnosing and assessing the severity of ACLF. When kidney failure occurs in ACLF patients, treatment varies depending on the presence and stage of acute kidney injury (AKI). In general, the diagnosis of AKI in cirrhotic patients is based on the International Club of Ascites criteria: an increase of 0.3 mg/dL or more within 48 hours or a serum creatinine increase of 50% or more within one week. This study underscores the importance of kidney failure or AKI in patients with ACLF by reviewing its pathophysiology, prevention methods, and treatment approaches.

( Jeong-ju Yoo ),( Young Chang ),( Eun Ju Cho ),( Sang Gyune Kim ),( Young Seok Kim ),( Yun Bin Lee ),( Jeong-hoon Lee ),( Su Jong Yu ),( Yoon Jun Kim ),( Jung-hwan Yoon ) 대한간학회 2018 춘·추계 학술대회 (KASL) Vol.2018 No.1

Aims: The optimal timing of emergency endoscopy in patients with variceal bleeding is remains unclear. Most guidelines recommend performing endoscopic evaluation and treatment within 12 hours after patient’s arrival, but there are few related studies. The aim of this study was to examine the association between timing of endoscopy and mortality of esophageal variceal bleeding in cirrhotic patients. Methods: This retrospective study included 274 of consecutive patients admitted to two tertiary hospitals in Korea due to esophageal variceal bleeding. Using descriptive statistics and Kaplan-Meier survival analyses, we analyzed the association between the timing of endoscopy and patients’ mortality. We adjusted confounding factors and balanced the baseline characteristics of the subjected patients using Cox proportional hazards model and inverse probability weighting (IPW) method. Results: A total of 173 patients received endoscopy within 12 hours after admission and 101 patients, after 12 hours. Endoscopy was performed after a median of 7.6 hours (interquartile range [IQR], 2.9-16.5) after admission. The median overall survival (OS) was 8.2 months (IQR, 1.4-25.9) months, and in-hospital mortality was 8.0%. Performing endoscopy within 12 hours was associated with longer OS than performing after 12 hours (33.2 vs. 23.5 months, log-rank P=0.01). Early endoscopy was independently associated with longer OS after adjusting presence of hepatocellular carcinoma, MELD score, and Glasgow-Blatchford score (adjusted hazard ratio [aHR] 1.61, 95% confidence interval [CI]=1.05-2.46, P=0.03). Also, after balancing baseline characteristics using IPW, endoscopy within 12 hours group consistently showed longer OS than endoscopy after 12 hours group (aHR 2.17, 95% CI=1.56-3.03; P=0.03). However, outcomes were not significantly different between the urgent (within 6 hours) and early endoscopy groups. Conclusions: Timing of endoscopy is associated with mortality in patients with esophageal variceal bleeding. It is important to perform emergency endoscopy within 12 hours, especially for high-risk patients.

Background/Aims: Patients with an intermediate stage of hepatocellular carcinoma (HCC) represent a highly heterogeneous population; therefore, many models have been proposed to predict the survival of these patients. The aim of this study was to evaluate the prognostic performance of a novel subclassification for tumors classified as Barcelona Clinic Liver Cancer (BCLC) stage B using the Model to Estimate Survival in Ambulatory HCC patients (MESIAH). Methods: This analysis was based on 377 patients with HCC treated at Seoul National University Hospital (training cohort) and 189 patients at the Soonchunhyang University Bucheon Hospital (validation cohort). Four subclassification systems were tested: MESIAH; original BCLC B subclassification (B1, B2, B3, and B4); modified model A (B1, B2, and B3+B4); and modified model B (B1, B2+B3, and B4). Results: Median survival progressively decreased from stage B1 through stages B2 to B3 according to the new MESIAH subclassification (p<0.001). Moreover, significantly different survival among contiguous stages was observed. In the multivariable Cox regression, the MESIAH subclassification was an independent predictor of overall survival (p<0.001). In terms of discrimination and calibration, MESIAH performed better than the original BCLC B subclassification, modified model A and modified model B. Conclusions: The MESIAH model would be an effective tool for stratifying heterogeneous BCLC stage B cancer, and the ability of this model to predict survival is better than that of the other previously proposed models.

Use of Beauty Products among U.S. Adolescents

Jeong-Ju Yoo,Hye-Young Kim 한국마케팅과학회 2010 Journal of Global Fashion Marketing Vol.1 No.3

The goal of this study is to 1) identify the types of beauty product used and to compare the frequency with which adolescent boys and girls use them; and 2) determine types of beauty product use are significant in relation to the degree of media influence among them in the United States. While cosmetic use is among the most common ways to enhance the appearance of adolescent girls, teenage boys in the United States have emerged as a sector of consumers in the health and beauty industry as well, which is reflected by their concern with personal hygiene and appearance as well as by increased sales (Shah, 2004). Consumer socialization research of adolescents has identified the media as a major source of influence (Brittain, 1963; Churchill and Moschis, 1979; Mascarenhas and Higby, 1993; Moore and Moschis, 1981; Robertson, 1979). Adolescents’ use of beauty products can be influenced by how much these young people are exposed to media sources, due to the media’s significant and pervasive influence on the lives of adolescents (Taveras, Rifas-Shiman, Field, Frazier, Colditz, and Gillman, 2004). Youth-oriented society has created images of adolescent beauty in magazines, television, the Internet, and on billboards and other types of advertisements (Labre and Walsh-Childers, 2003). Teenagers are believed to be among the heaviest users of many mass media outlets, particularly specialized magazines (Arnett, Larson, and Offer, 1995). The media provide information on fashion and beauty, which have the potential to influence adolescents in the process of their social development and emerging sense of identity. The data were collected from 357 (155 males, 202 females) middle- and high-school students in the United States between the ages of 11 and 18 years, with an average age of 14.3 years. Of those sampled, the majority of them (328; 93.18%) were Caucasian. A pilot study was conducted in order to identify the beauty products used for the development of the survey instrument. Ten product categories were identified for the instrument development as follows: 1) shampoo and/or conditioner; 2) hairstyling gel/hairspray; 3) hair dye; 4) body products (e.g., body wash, lotion); 5) facial products (e.g., facial soap, moisturizer); 6) perfume; 7) acne treatment products; 8) hygiene products (e.g., deodorant, toothpaste); 9) cosmetics; and 10) nail products. The participants were given a cover letter and a questionnaire. The first part of the questionnaire contained media influence items (α=0.79) developed by Bearden et al. (1989). The second part of the questionnaire contained items concerning beauty product use. The third part of the questionnaire contained demographic items, which collected information on the age, gender, and ethnicity of the sample. The data were analyzed using descriptive statistics and MANOVA (Multivariate Analysis of Variance). Results revealed that adolescent boys reported using a variety of products with varying degrees of frequency. On a daily basis, 84.7% of boys (n=127) used shampoo/conditioner, followed by hygiene products (84.5%; n=125), body products (61.5%; n=91), and facial products (37.2%; n=55). Adolescent boys occasionally used hairstyling gel/spray (43.2%; n=64) and acne treatments (49.0%; n=71). Most of them had never used nail products (87%; n=127), hair dye (84.5%; n=125), cosmetics (83.2%; n=124), or perfume (65%; n=97). Adolescent girls reported using a variety of products daily. A total of 93.5% (n=186) used hygiene products, followed by shampoo/conditioner (90.1%; n=181), body products (84.9%; n=169), facial products (74.3%; n=150), perfume (65.8%; n=129), cosmetics (62.2%; n=125), and acne treatments (51.3%; n=101) on a daily basis. Occasionally, 51.2 % (n=103) of adolescent girls used hairstyling gel/spray, hair dye (41.5 %; n=81), as well as nail products (71%; n=142).

( Jeong-ju Yoo ),( Jeong-hoon Lee ),( Young Chang ),( Eunju Cho ),( Su Jong Yu ),( Yoon Jun Kim ),( Jung-hwan Yoon ),( Seoul Liver Group ) 대한간학회 2016 춘·추계 학술대회 (KASL) Vol.2016 No.1

Aims: Advanced Hepatocellular carcinoma (HCC) embraces various clinical conditions: major vessel invasion, extrahepatic metastasis, and poor performance status. The aim of this study was to establish a prognostic scoring system using independent factors and to propose sub-classification of Barcelona-Clinic Liver Cancer (BCLC) stage C. Methods: This retrospective study included consecutive patients who received sorafenib for BCLC stage C HCC at a single tertiary hospital in Korea. Factors affecting overall survival were analyzed. Cox proportional hazard model was used to develop a point score system, and internal validation was performed by 5-fold cross-validation. The performance of model to predict risk was assessed by area under the curve (AUC) and Hosmer-Lemeshow test. Results: Among 756 patients who received sorafenib for HCC between 2008 and 2014, 612 (81.0 %) were classified as BCLC stage C and included in this study. Mean age of the patients were 60.3±10.7 and 84.2% were male. The patients were further classified into strata depending on their performance status (ECOG 0 or 1). Five independent prognostic factors (Child-Pugh score, alpha fetoprotein, tumor type, extrahepatic metastasis, and portal vein invasion) were identified and used in the prognostic scoring system. The scoring system gave from one to ten points for the presence each factor, resulting in a total score ranging from 0 to 24 (Table 1). This scoring system showed good discrimination (area under time-dependent ROC curve [AUC]=0.734-0.818) and calibration functions. (Figure 1) Cases were analyzed in the three risk groups according to the total score. In internal validation, AUC was similarly maintained (0.734 at month 12). Conclusions: The result of heterogeneity of patients with BCLC stage C HCC requires sub-classification of advanced HCC. The prognostic scoring system using five independent factors is useful in predicting the survival of patients with BCLC stage C HCC.
