The purpose of this study was to examine the relations between maternal traditional-modern values, childrearing practices and children's social behaviors. The subjects were 500 fifth grade elementary school children and their mothers, and teachers, and peers in the same classroom. The data were collected through questionnaires on maternal traditional values, perceived maternal childrearing practices, and children's social behaviors. Traditional maternal values focused on familial collectivism and politeness. The major results were as follows: (1) Maternal traditional values were positively related to childrearing practices in both maternal affection rational guidance and authoritarian control. (2) Maternal traditional values did not directly influence children's social behavior but showed an indirect moderating effect through maternal childrearing practices. Implications were discussed in terms of the importance of traditional values on childrearing behavior as well as the development of children.

This study analyzes the values of vintage in Korean fashion prosumer's activities and elevates the values as one characteristic of Korean modern fashion. The methodology included literary and empirical studies as well as prosumer and modern Korean vintage fashion literary studies. In-depth interviews were done to analyze the values of vintage in fashion prosumer's activities. The values of vintage fashion for Millennials are creative activities based on public interest, expanded reproducing through sharing daily looks and self-expression through the scarcity of vintage clothing. Prosumer characteristics are self-satisfaction and sharing. Fashion prosumer's vintage trends are new-tro, communication, cultural complex, and sharing of daily life. The formativeness in fashion prosumer's activities are heritage, text, activity and image. The meanings are creation, communication, experience and sharing. Fashion prosumers are developing the new genre of 'vintage fashion activity'; in addition, values towards vintage fashion activity are also drawing international interest.

The purpose of this study is to examine how the mother's educational aspirations and household's characteristics have an effect on the likelihood of private educational expenditures and the amount of private educational expenditures. Factor analysis, probit and tobit analyses were used. The main findings can be summarized as the following: The mother's educational aspirations for intrinsic values is higher than for extrinsic values. The mother's educational aspirations for extrinsic values, household's assets, and residing in Seoul rather than residing in Incheon had significant positive effects on the likelihood of private educational expenditures. However, the child's birth order had a significant negative effect on the likelihood of private educational expenditures. The mother's educational aspirations for extrinsic values, the mother's education level, household's income, household's assets, and residing in Seoul rather than residing in Incheon had significant positive effects on the amount of private educational expenditures. However, the child's birth order had a significant negative effect on the amount of private educational expenditures. Findings from this study offer several implications. First, the mother's educational aspirations for extrinsic values rather than for intrinsic values has an effect on private educational expenditures. Unless the mother's educational aspirations have been changed to pursuing intrinsic values, the private educational expenditures cannot be reduced. Second, the polarization of the household's income and assets could bring about the polarization of private educational expenditures, which can lead to the intergenerational income polarization.

The use of iodine S values derived using the International Commission Radiological Protection (ICRP) phantoms may introduce significant bias in internal dosimetry for Koreans due to anatomical variability. In the current study, we produced an extensive dataset of Korean S values for selected five iodine radioisotopes (I-125, I-129, I131, I-133, and I-134) for use in radiation protection. To calculate S values, we implemented Monte Carlo simulations using the Mesh-type Reference Korean Phantoms (MRKPs), developed in a high-quality/fidelity mesh format. Noticeable differences were observed in S value comparisons between the Korean and ICRP reference phantoms with ratios (Korean/ICRP) widely ranging from 0.16 to 6.2. The majority of S value ratios were lower than the unity in Korean phantoms (interquartile range = 0.47-1.28; mean = 0.96; median = 0.69). The S values provided in the current study will be extensively utilized in iodine internal dosimetry for Koreans.

This paper focuses on the application of a novel mathematical limit approach derived for K/S values in reactive dyeing of cotton fabrics. The relation obtained from Kubelka-Munk equation is used because the Kubelka-Munk equation is the basic relationship among fabric reflectance, fabric dye content and dyestuff characteristics. The limit approach derived in a former paper is applied to the laboratory dyeings and the dyeing behavior of some reactive dyes on cotton knitted fabric has been obtained. The results of the laboratory experiments are discussed using the new mathematical approach. When the actual K/S values obtained from the dyeings and the calculated K/S values derived by the limit approach are considered independently, it is observed that the limit relation is val id for low dye concentration applications. When the K/S values are calculated taking the K/S value of the initial dyeing concentration $(0.1\;\%\;owf)$ as the starting concentration by applying the result of the derived limit approach, the calculated K/S values fit with the ones obtained in actual dyeings. It is concluded that the novel approach presented in the paper can be used in calculating the K/S values when the initial dyeings at low dye concentrations are carefully carried out.

Objectives This study examined variations in the perceptions of dioxin risk among social groups defined by geographical living location, environmental education, and occupation. Dioxin risk perceptions were analyzed according to values, risk awareness, knowledge, and behavioral preferences. Methods A quasi-experimental survey was designed and conducted on individuals from seven experimental groups in Jeonju city, South Korea, including: people living near incineration facilities; people living far from incineration facilities; governmental experts; non-governmental organization members; office workers in developmental institutes or banks; students who were enrolled in environmental-related classes; and students who were enrolled in business-related classes. Results The results show variations among groups in values, awareness and behavioral preferences. Particular attention should be given to the result that groups with higher connectedness-to-nature values show higher willingness-to-act (WTA) for risk reduction. Result s can be summarized as follows. First, awareness is associated with one's geographical setting. Second, values and WTA behaviors are related to one's environmental-related education and occupation. Third, values are significantly related to WTA behaviors. Conclusions Different cultures, in terms of values or worldview, among groups influence their perceptions of dioxin risk and choices of risk reduction behaviors. It is important to consider values in communicating complicated long-term risk management involving public participation. Further research should be continuously conducted on the effects of multiple dimensions of values on one's WTA for risk reduction behaviors.

The purpose of this study was to investgate the social meaning and consumption values expressed on apparel advertisements In Teena-ger's magazines from 1976 to 1996. The results of this study were as follows. 1. As the number of the model in apparel advertisements was more than two people it was closely related to conformity and peer ac-ceptance of adolecent's developmental task. Also There were increasing number of foreign models and attractive and famous signers and talents. 2. The trend of appeals showed changing time and society. Since 1990 post-modern ap-proach has increased whereas rational and emotional approach were dominated in 1970s and 1980s. 3, The major consumption values in apparel advertisements were social value emotional value. From 1990 there were variety in consumption values related to adolescent's ap-parel advertisements. This results represented the possibility that apparel advertisements in adolescent's maga-zines not only mirror but mold change of con-sumption values and life style in adolescent. Especially to understand and predict the new generation in Korea educators and practi-tioners in Junior Fashion Market must try to study the current adolescent's life style and consumption values systematically.

The purpose of this study was to classify the consumption values of 20's and 30's female consumers, identify the differences among the consumption value groups, and analyze purchase behaviors of imported fashion luxury brands according to the consumption value types. The subjects were 518 women who purchased luxury bags. The results of the study were as follows. First, as a result of cluster analysis to classify the consumption values of 20's and 30's female consumers, 4 groups were identified as "rare and emotional pursuit group", "functional pursuit group", "fashion pursuit group", and "social and conspicuous pursuit group". Second, 4 groups showed different luxury bag purchase behaviors, such as purchase motivation, purchase selection criteria, information source, purchase frequency, purchase cost of one time, purchase cost of year, the number of possession, purchase place, and store selection criteria. Third, rare and emotional pursuit group ranked the first in terms of product, price, and store satisfaction. Therefore, consumption values were identified as the important factor suggesting purchase behaviors of female consumers in 20's and 30's.

PURPOSE. This study inspects the effect of incorporating halloysite nanotubes (HNTs) into polymethyl methacrylate (PMMA) resin on its flexural strength, hardness, and Young's modulus. MATERIALS AND METHODS. Four groups of acrylic resin powder were prepared. One group without HNTs was used as a control group and the other three groups contained 0.3, 0.6 and 0.9 wt% HNTs. For each one, flexural strength, Young's modulus and hardness values were measured. One-way ANOVA and Tukey's test were used for comparison (P<.05). RESULTS. At lower concentration (0.3 wt%) of HNT, there was a significant increase of hardness values but no significant increase in both flexural strength and Young's modulus values of PMMA resin. In contrast, at higher concentration (0.6 and 0.9 wt%), there was a significant decrease in hardness values but no significant decrease in flexural strength and Young's modulus values compared to those of the control group. CONCLUSION. Addition of lower concentration of halloysite nanotubes to denture base materials could improve some of their mechanical properties. Improving the mechanical properties of acrylic resin base material could increase the patient satisfaction.
