Adolescence is vulnerable to various Health Risk Behaviors (HRB). These behaviors can affect his remaining life as well as adolescence, thus prevention of HRB is a critical issue in health education. This study is aimed to provide basic information for prevention of HRB. Thus, this study was conducted to analyze the impact of peer group's health risk behaviors on health risk perception (HRP) and that of health risk perception on health risk behaviors based on 832 respondents. The 852 subjects were selected in six middle and high schools in Seoul through random sampling. Data were collected from September, 18-October, 21, 1998, and the 832 data were analyzed after excluding the 20 incomplete and inaccurate data. Questionnaire items and measures are based on an instrument to measure Perceived Health Risk Perception, which Hodge B.C. developed in 1992. Cronbach alpha is used to test the reliability. The reliability of HRP and HRB is 0.9473, 0.8768 in this study, Statistical analysis divided into four phases. First, the impact of socio-demographic characteristics on HRP is analyzed by oneway ANOV A. Male students have lower HRP than female students. As grade goes up, HRP is getting lower. Perceived higher concern of parents and HRP are correlated. And the experience of school health education and HRP are correlated. Second, the impact of peer group's HRB on the HRP is analyzed by linear regression. Peer group's HRB and HRP are negatively correlated, Third, the impact of HRP on HRB is analyzed by linear regression. There is a correlation between high HRP and low HRB. Fourth, Powerful impact factors on HRB are analyzed by stepwise multiple regression. Grade, gender, peer group's HRB, and related HRP is entered as independent variables. Because of correlation between entered variables, three interaction variables between grade, gender, peer group's HRB and related HRP also entered, In general, peer group's HRB is the most accountable factor to HRB. And Interaction variable between HRP and peer group's HRB and HRB are negatively correlated. These results indicate that HRP may reduce the impact of peer group's HRB on HRB. Some recommendations are as follows: First, health educational programs suitable for gender and grade are required. Second, a systematic cooperation between school and home is necessary for effective prevention of HRB. Third, the educational effect for decreasing HRB by increasing HRP is statistically assisted. However, peer group has much stronger impact on HRB than subjective HRP, thus special consideration and management are necessary for peer group which does HRB more frequently.

Purpose: The mechanism for the pathogenesis of adriamycin (ADR)-induced cardiomyopathy is not yet known. Different hypotheses include the production of free radicals, an interaction between ADR and nuclear components, and a disruption in cardiac-specific gene expression. Apoptosis has also been proposed as being involved in cardiac dysfunction. The purpose of this study was to determine if apoptosis might play a role in ADR-induced cardiomyopathy. Methods: Male Sprague-Dawley rats were separated into 2 groups: the control group (C group) and the experimental group (ADR 5 mg/wk for 3 weeks through intraperitoneal injections; A group). Echocardiographic images were obtained at week 3. Changes in caspase-3, B-cell leukemia/lymphoma (Bcl)-2, Bcl-2-associated X (Bax), interleukin (IL)-6, tumor necrosis $factor-{\alpha}$, brain natriuretic peptide (BNP), troponin I, collagen 1, and collagen 3 protein expression from the left ventricle tissues of C and A group rats were determined by Western blot. Results: Ascites and heart failure as well as left ventricular hypertrophy were noted in the A group. Ejection fraction and shortening fraction were significantly lower in the A group by echocardiography. The expression of caspase-3, Bax, IL-6, BNP, collagen 1, and collagen 3 were significantly higher in the A group as compared with the C group. Protein expression of Bcl-2 decreased significantly in the A group compared with the C group. Conclusion: ADR induced an upregulation of caspase-3, Bax, IL-6, and collagen, as well as a depression in Bcl-2. Thus, apoptosis and fibrosis may play an important role in ADR-induced cardiomyopathy.

The purpose of this study was to investigate the dimensions of fashion lifestyle, to examine the relationship between fashion lifestyle and internet advertising effect, and to identify the moderating effect of fashion lifestyle on the relationship between advertising types and advertising effects. Using dependent variables as internet advertising effects(i.e., attitude to advertising, attitude to product, attitude to brand), advertising types (i.e., banner, website e-mail types) and fashion lifestyle were used as independent variables. For the study, a sample of 152 apparel consumers participated in this survey research. The survey of design with a questionnaire was employed. Three types of fashion advertisement were included as banner type, website type, and e-mail type. For each type, two samples were included for the study. Questionnaire was developed with the html language and data collection was done through the internet on October 2000. For data analysis, descriptive statistics(i. e., frequency, percent), factor analysis, reliability analysis, linear regression and ANOVA were used. First, fashion lifestyle was classified with the seven dimensions: personality seeking group, planning purchase group, fashion leader group, fashion information seeking group, media preference group, commonness/traditional group, fashion follower group. Second, fashion lifestyle had signification effects on advertising effects. In the group of fashion lifestyle, fashion Information seeking group and planning purchase group were found to influence on the attitude toward advertising, and planning purchase type was influenced to attitude toward brand and attitude toward product. Third, main effects of fashion lifestyle were found to be significant. The correlation and interaction effects of fashion lifestyle and internet advertisement types were not significant.

The purpose of this study was to find out differences of visual evaluation according to perceiver's personality(introvert-extrovert) and clothing styles. Subjects were 120 women in age from 18 to 31 years in Seoul. The stimuli of 7 clothing styles were used for visual evaluation. Three dimensions of visual evaluation were derived by falters analysis: elegance, activity individuality, and fashionability. The pants suit was estimated low in activity individuality and fashionability, but the hip-hop style high in activity individuality. The skirt suit was rated high in elegance, but the 8th length pants low in elegance. Personality had significant influences on the evaluation of activity individuality. Extrovert women perceived all stimuli to be more active and individual than introvert. Fashionability factor had an interaction effect by personality and clothing expenses. The introvert women in low clothing expenses group evaluated the stimuli to be more fashionable than the introvert in high clothing expenses group. There were significant differences in preference of all clothing styles according to personality. Extrovert women liked 8th length pants more than introvert. The introvert women in low clothing expenses group liked the skirt suit less than the extrovert.

Alarm system performance is a critical aspect of safety. While existing research has extensively examined the influence of acoustic attributes on alarm performance, consonance's impact remains largely uncharted territory. This study bridges this research gap by investigating the effect of consonance on alarm systems. We extend our investigation to encompass not only the sound characteristics of the alarm but also the acoustic qualities of the surrounding environment, recognizing their potential impact on alarm efficacy. Prior studies consistently link consonance to annoyance levels, resulting in a negative user experience. Thus, we explore the relationship between consonance and alarm system performance, with a particular focus on modulating annoyance as an explanatory factor. Utilizing an oddball paradigm, we categorized standard and oddball sounds into consonant and dissonant types, creating four sound combinations. Participants were asked to respond to the irregularly presented oddball sounds while ignoring the constantly presented standard sounds. Our results reveal significant differences between groups, with the Standard Consonant/Oddball Dissonant (SC/OD) group displaying notably slower response times than the Standard Dissonant/Oddball Consonant (SD/OC) group. This reaction time variation aligns with differences in annoyance levels, as the SC/OD group reports higher annoyance, suggesting that reaction time discrepancies may be linked to increased arousal due to heightened annoyance.

The purpose of this study was to clarify the factors that characterize the fashion brand online communities that have a high participation rate among high school students, and to determine the impact of those factors on the high school students' commitment to the community, especially in relation to their demographics. The study was implemented through a descriptive survey method using an online questionnaire. The sample consisted of 301 members of online fashion brand communities operated on the Daum portal site. The data were analyzed by frequency, factor analysis, and regression analysis. The results are as follows: (1) Factor analysis revealed that the characteristics of a fashion brand online community are associated with three factors ; compensation/interest, interactivity, and information. (2) Regression analysis showed that the more compensation/interest, opportunity for interaction, and information the community provides, the more likely high school student members are to show a higher level of commitment to the community. (3) There was no difference in the effect of community attribute factors on the high school student members' commitment to the community according to gender. The group of students majoring in human and liberal education was the most influenced by the attributes of fashion brand online communities. The interactivity factor had a greater impact on the group of students majoring in art and physical education than on the other groups. The greater the use of the Internet, the greater the impact of community attributes on commitment. (4) In the process of developing an online community, marketers should fully consider the fact that information factors have the biggest impact on high school students' commitment to the community. Therefore, greater effort should be made to differentiate between community attributes based on high school students' majors and their amount of Internet use in order to motivate commitment to the community and brand loyalty as well.

This study aims to identify the sense of community influencing Intent to continue farming for young farmers to sustain their farming. Data were was collected from 124 young farmers during October 2023 among members of the 4-H youth organization in Gyeonggi Province, South Korea. As a result of factor analysis, the sense of community was classified into three dimensions: sense of belonging, social interaction, and community bond. It was found that the intention to continue farming was classified into two dimensions: economic and social factors. Results showed that participants with less than five years of 4-H involvement had higher community awareness than those with more than five years. This study suggests that early-stage participants be more influenced by group belonging and interaction. Additionally, community awareness positively influenced both economic and social aspects of farming sustainability. Thus, higher community awareness among young farmers enhances the sustainability of their practices. This study is significant as it addresses the previously unexplored relationship between young farmers' community awareness and farming sustainability, suggesting that fostering community awareness can improve sustainable agricultural practices.

Considering the online idea generation, or web-storming, system would be used differently by space designers depending on their job characteristics, the present study tested the usability of web-storming using a factor correlation table with a designer group in the field. Then, for analyses, the results were compared with the previous findings on the usability of web-storming in a design administrator group to suggest comprehensive measures applicable to web-storming. The questionnaire results were analysed following a process of observation-interpretation-application, and the space design process and web-storming function factors were also analysed based on a factor correlation table. The analyses found that the most correlated space design process in both administrator and designer groups was the schematic design phase, and that the correlation started to lower upon division of labour. The assessment phase was found significantly different between the designer group and the administrator group. The assessment phase showed the second highest correlation in the designer group. In terms of the aspects related to project operation, the correlation was found higher in the designer group. Based on the findings, new applicable measures to each phase of web-storming were derived and summed up to suggest how to take advantage of web-storming in the field.

Background: Inflammation is known to underlie the pathogenesis in neuropathic pain. This study investigated the anti-inflammatory and neuroprotective mechanisms involved in antinociceptive effects of co-administration of acetaminophen and L-carnosine in chronic constriction injury (CCI)-induced peripheral neuropathy in male Wistar rats. Methods: Fifty-six male Wistar rats were randomly divided into seven experimental groups (n = 8) treated with normal saline/acetaminophen/acetaminophen + L-carnosine. CCI was used to induce neuropathic pain in rats. Hyperalgesia and allodynia were assessed using hotplate and von Frey tests, respectively. Investigation of spinal proinflammatory cytokines and antioxidant system were carried out after twenty-one days of treatment. Results: The results showed that the co-administration of acetaminophen and L-carnosine significantly (P < 0.001) increased the paw withdrawal threshold to thermal and mechanical stimuli in ligated rats compared to the ligated naïve group. There was a significant (P < 0.001) decrease in the levels of nuclear factor kappa light chain enhancer B cell inhibitor, calcium ion, interleukin-1-beta, and tumour necrotic factor-alpha in the spinal cord of the group coadministered with acetaminophen and L-carnosine compared to the ligated control group. Co-administration with acetaminophen and L-carnosine increased the antioxidant enzymatic activities and reduced the lipid peroxidation in the spinal cord. Conclusions: Co-administration of acetaminophen and L-carnosine has anti-inflammatory effects as a mechanism that mediate its antinociceptive effects in CCI-induced peripheral neuropathy in Wistar rat.
