This study aimed to examine the association between material hardship and alcohol use among low-income households in Korea, with particular attention to whether the association was mediated by family conflict and self-esteem. Using a nationally representative sample of 960 low-income households, this study conducted a path analysis to test a structural model liking material hardship to alcohol use through family conflict and self-esteem. The significance of indirect paths was tested by a Sobel test. This study found that experiencing material hardship was directly associated with low levels of coping skills for family conflict and low levels of self-esteem, but not with alcohol use. However, material hardship was indirectly associated with alcohol use through low levels of coping skills for family conflict as well as low levels of self-esteem. The findings of this study suggest that experiencing material hardship among low-income households would be a socio-structural stressor for alcohol use, particularly in that it increases secondary role and intra-psychic strains. Implications to address material hardship and alcohol use among low-income households were discussed.

Understanding consumers' preferences and use of media types is imperative for marketing and advertising managers, especially in today's fragmented market. A clear understanding assists managers in making more effective selections of appropriate media outlets, yet individuals' choices of type and use of media are based on a variety of characteristics. This paper examines one personality trait, sensation seeking, which has not appeared in the literature examining "new" media preferences and use. Sensation seeking is a personality trait defined as "the need for varied, novel, and complex sensations and experiences and the willingness to take physical and social risks for the sake of such experiences" (Zuckerman 1979). Six hypotheses were developed from a review of the literature. Particular attention was given to the Uses and Gratification theory (Katz 1959), which explains various reasons why people choose media types and their motivations for using the different types of media. Current theory suggests that High Sensation Seekers (HSS), due to their needs for novelty, arousal and unconventional content and imagery, would exhibit higher frequency of use of new media. Specifically, we hypothesize that HSS will use the internet more than broadcast (H1a) or print media (H1b) and more than low (LSS) (H2a) or medium sensation seekers (MSS) (H2b). In addition, HSS have been found to be more social and have higher numbers of friends therefore are expected to use social networking websites such as Facebook/MySpace (H3) and chat rooms (H4) more than LSS (a) and MSS (b). Sensation seekers can manifest into a range of behaviors including disinhibition,. It is expected that alternative social networks such as Facebook/MySpace (H5) and chat rooms (H6) will be used more often for those who have higher levels of disinhibition than low (a) or medium (b) levels. Data were collected using an online survey of participants in extreme sports. In order to reach this group, an improved version of a snowball sampling technique, chain-referral method, was used to select respondents for this study. This method was chosen as it is regarded as being effective to reach otherwise hidden population groups (Heckathorn, 1997). A final usable sample of 1108 respondents, which was mainly young (56.36% under 34), male (86.1%) and middle class (58.7% with household incomes over USD 50,000) was consistent with previous studies on sensation seeking. Sensation seeking was captured using an existing measure, the Brief Sensation Seeking Scale (Hoyle et al., 2002). Media usage was captured by measuring the self reported usage of various media types. Results did not support H1a and b. HSS did not show higher levels of usage of alternative media such as the internet showing in fact lower mean levels of usage than all the other types of media. The highest media type used by HSS was print media, suggesting that there is a revolt against the mainstream. Results support H2a and b that HSS are more frequent users of the internet than LSS or MSS. Further analysis revealed that there are significant differences in the use of print media between HSS and LSS, suggesting that HSS may seek out more specialized print publications in their respective extreme sport activity. Hypothesis 3a and b showed that HSS use Facebook/MySpace more frequently than either LSS or MSS. There were no significant differences in the use of chat rooms between LSS and HSS, so as a consequence no support for H4a, although significant for MSS H4b. Respondents with varying levels of disinhibition were expected to have different levels of use of Facebook/MySpace and chat-rooms. There was support for the higher levels of use of Facebook/MySpace for those with high levels of disinhibition than low or medium levels, supporting H5a and b. Similarly there was support for H6b, Those with high levels of disinhibition use chat-rooms significantly more than those with medium levels but not for low levels (H6a). The findings are counterintuitive and give some interesting insights for managers. First, although HSS use online media more frequently than LSS or MSS, this groups use of online media is less than either print or broadcast media. The advertising executive should not place too much emphasis on online media for this important market segment. Second, social media, such as facebook/Myspace and chatrooms should be examined by managers as potential ways to reach this group. Finally, there is some implication for public policy by the higher levels of use of social media by those who are disinhibited. These individuals are more inclined to engage in more socially risky behavior which may have some dire implications, e.g. by internet predators or future employers. There is a limitation in the study in that only those who engage in extreme sports are included. This is by nature a HSS activity. A broader population is therefore needed to test if these results hold.

In the intensely competitive global fashion market, the use of cultural elements to enhance design has become increasingly widespread. However, there is a lack of research on challenges and opportunities associated with integrating cultural elements of Minhwa into fashion design. Moreover, diverse approaches to incorporate Korean cultural elements into contemporary fashion designs are still needed. This study aims to reveal the real-world challenges relating to the incorporation of Korean cultural elements, including Minhwa, into fashion design and to clarify the possibility of applying Lin's cultural levels to cultural aspects in accordance with experts' views. To establish a theoretical foundation, the literature review on cultural design and Minhwa studies was conducted. It analyzes Minhwa to gain an understanding of the characteristics associated with different cultural levels. In-depth interviews with fashion industry professionals and Minhwa artists were conducted to ascertain their attitudes toward Minhwa use. The study's major findings were threefold. First, the cultural design facilitates the introduction, promotion, understanding, and maintenance of the culture. Since Minhwa offers rich inspiration linked to Korean culture, Minhwa-related designs can provide new perspectives while still having commercial potential. Second, however, the limitations of existing cultural designs included their being outdated, superficial without interpretation, unsophisticated, or limited. Furthermore, the use of Minhwa is limited since it is difficult to avoid creating superficial and unsophisticated designs in the real world. Third, approaching Minhwa at different cultural levels can promote diverse thinking and reduce the challenges of Minhwa use in design, but the major challenge remains visual expression.

The goal of this study was to investigate how daily experiences of schoolwork and leisure activities explained cultural differences in levels of adolescent depression. A combined sample of 58 high school seniors in Korea and 62 high school seniors in the United States reported time use patterns and affect states in daily activities and levels of depression. The time use pattern in daily independent study during class hours and in active leisure activities significantly explained cultural differences in levels of depression. Affect states in all schoolwork activities and passive leisure activities also significantly explained cultural differences in levels of depression. These findings suggest that Korean adolescents' experience of 'exam hell', particularly the lack of active leisure activities and more negative emotional experiences of daily activities are partly responsible for their higher depression relative to American counterparts.

The use of aromatherapy for the reduction of anxiety levels during dental treatment procedures has been well established in the literature; however, there is limited evidence regarding its efficacy. The present meta-analysis is an attempt to assess the association between the use of aromatherapy and anxiety levels among dental patients. A comprehensive search was conducted across Medline, Scopus, Web of Science, EBSCO host, Cochrane databases, and Google Scholar for studies evaluating aromatherapy and anxiety level among dental patients. PRISMA guidelines were followed for the meta-analysis. Randomized and cluster-randomized trials comparing aromatherapy with controls were included. The random-effects model was used to assess the mean differences in anxiety levels of patients visiting dental OPD. The significance value was set at P < 0.05. Six studies were identified that met the requirements for inclusion. Aromatherapy was significantly associated with reduction in patient anxiety levels during dental treatment (pooled mean difference: -3.36 [95% CI, -3.77 - -2.95, P = 0.00001). Low heterogeneity was noted between studies (I² = 1%, P = 0.41) analyzed in the meta-analysis. High certainty of the evidence was obtained from the association between the use of aromatherapy and dental anxiety. This meta-analysis suggests that aromatherapy is effective in reducing dental anxiety. When used judiciously, the results of this work should encourage the use of aromatherapy to reduce patient anxiety levels during dental procedures

Objective: This study aimed to examine the difference in toddlers' accumulated cortisol levels based on childcare experience in toddlerhood and the relationship between temperament and accumulated cortisol levels. Methods: Hair sample were collected for measure accumulated cortisol level in 87 toddlers. The Early Childhood Behavior Questionnaire (ECBQ) was used to measure temperament. Results: First, toddlers in childcare showed higher accumulated cortisol levels than in-home toddlers. Second, toddlers in childcare, exhibited a significant correlation between accumulated cortisol levels and surgency. Third, the accumulated cortisol levels of in-home toddlers exhibited a significant correlation with negative affect. In this research, there was significant range in the accumulated cortisol level according to childcare use, and the factors related to accumulated cortisol levels were different in each context. Conclusion: The results of this research support the "susceptibility to context of HPA axis" and imply a needed discussion about the effect of childcare experiences in toddlerhood.

This study was trying to find the differences of the levels of e-commerce system satisfaction and a relationship between system satisfactions and behavioral intention to use e-commerce system continuously. Based on the previous studies, we identified the factors of system satisfaction that were consist of system readiness, accuracy, content, ease of use, timeliness and IT Support. The system satisfaction levels of martial status and the training status of hospitals had significant differences. In martial status, un-married managers had higher levels of ease of use and timeliness than the married. In this result, we might consider an age effect for younger persons are more likely to use IT and have more satisfaction perceptions. Rather than training hospitals, non-training hospitals had higher level of ease of use and IT support, which could be interpreted as e-commerce systems of training hospitals might not match their own managerial purposes and need an improvement of their system functionalities. This study also identified that the factors of system satisfaction has a relationship with behavioral intentions. Except accuracy and IT support of all six system satisfaction factors, four factors were significantly correlated with system usage intentions in their e - commerce works.

This study examines the effects of two motivational orientations on the use of language learning strategies at overall, category, and specific-item levels. 184 students (males and females) from a Korean university responded to the following two questionnaires: the Motivational Orientation Questionnaire (MOQ) developed by the author and Oxford's Strategy Inventory for Language Learning (SILL). The results showed that both integratively- and instrumentally-oriented students were moderate strategy users overall. Integratively-oriented learners were found to use learning strategies more often and a broader spectrum of strategies than instrumentally-oriented learners. A noteworthy finding, however, is that strategy use was not motivation orientation-specific. In other words, the two motivational groups were found to share the similar patterns of strategy use. Independent samples t test results revealed that integratively-oriented students exhibited significantly greater use of overall strategy than instrumentally-oriented students. This phenomenon held true for the use of cognitive, metacognitive, and social categories. At the specific item levels, 13 of the total 50 individual strategies were shown to be employed significantly more often by integratively motivated learners than by their instrumentally motivated peers.

As exhaust emission standards for new passenger cars amended in 1987 have become more stringent, vehicle manufacturers have employed three-way catalyst in order to meet these requirements. The purpose of this study was to gather informations on new emission control systems in customer use for in-use vehicles from the 1987 through 1992 model years were capable of achieving low exhaust emission levels although high levels do occur due to defects, deterioration or maladjustments with the emission control equipment. The vehicles with closed loop electronic control fuel injection system emitted low exhaust emission, but the carburetor control system equipped vehicles emitted high exhaust emissions and the high mileage vehicles exhibited higher average emissions than low mileage vehicles. It was also found that the useful life of 80, 000km is very important to maintain the low emission levels within customer service period.

Objective: The aim of the study was to evaluate the effects of different nitrate levels (150, 300, 450, and 600 ppm $KNO_3$) on the volatile compounds and some other properties of pastırma. Methods: Pastırma samples were produced under the controlled condition and analyses of volatile compounds, and thiobarbituric acid reactive substances (TBARS) as an indicator of lipid oxidation, non-protein nitrogenous matter content as an indicator of proteolysis, color and residual nitrite were carried out on the final product. The profile of volatile compounds of pastırma samples was analyzed by gas chromatography/mass spectrometry using a solid phase microextraction. Results: Nitrate level had a significant effect on pH value (p<0.05) and a very significant effect on TBARS value (p<0.01). No significant differences were determined in terms of $a_w$ value, non-protein nitrogenous substance content, color and residual nitrite between pastırma groups produced by using different nitrate levels. Nitrate level had a significant (p<0.05) or a very significant (p<0.01) effect on some volatile compounds. It was determined that the amounts and counts of volatile compounds were lower in the 450 and especially 600 ppm nitrate levels than 150 and 300 ppm nitrate levels (p<0.05). While the use of 600 ppm nitrate did not cause an increase in residual nitrite levels, the use of 150 ppm nitrate did not negatively affect the color of pastırma. However, the levels of volatile compounds decreased with an increasing level of nitrate. Conclusion: The use of 600 ppm nitrate is not a risk in terms of residual nitrite in pastırma produced under controlled condition, however, this level is not suitable due to decrease in the amount of volatile compounds.
