Parental satisfaction is the foundation of a happy family. It is a key factor in overall life satisfaction and also a critical variable in the development of children, and thus an education program aimed at parental satisfaction improvement is needed. This study attempts to determine basic elements of parental satisfaction that could enable better parental education programs. To accomplish this, mother's parental satisfaction and factors related to it were examined. The subjects were 641 mothers of primary school and middle school students aged 10, 12, and 14 residing in Seoul, Pohang and Kwangyang. Structured self-administered questionnaires were used to ascertain mothers' parental role satisfaction, mothers' role values, children related variables, mother related variables, father related variables, and home environment variables. The findings indicate that the variables related to parental satisfaction are multi-dimensional, that mothers' parental satisfaction can be improved by other family member's effort, and that a family's external characteristics are less important than its internal characteristics. These results imply that it is essential to include the characteristics of the family system when designing parental education programs. Furthermore, the role of specific family members, namely the husband, should be expanded in more supportive ways in Korean families to improve mothers parental satisfaction.

The objectives of this study were to classify the contents of clothing image preferences of Korean and American students, and to examine how clothing image preferences vary according to sex role identity, sex, and culture. A woman's clothing image preference inventory and the Bem Sex Role Inventory were administered to 127 Korean students and 116 American students. Sex role idendity was classified into androgynous, masculine, feminine, and undifferentiated type. 1. Four segments of woman's clothing image preference derived by factor analysis : F. 1 'splendid-plain' ; F. 2 'feminine-masculine' ; F. 3 'casual-formal' ; F. 4 'classic-contemporary'. 2. Americans prefered splendid image more than did Koreans. Androgynous-typed males liked splendid image most among American male subjects. 3. There was interaction effect between sex and culture on feminine-masculine image preference. In Korean students, males liked feminine image much more than did females. Masculine-typed females liked masculine image most among American female subjects. 4. Koreans prefered casual image more than did Americans. 5. There was interaction effect between sex role identity, sex, and culture($4{\times}2{\times}2$) on classic-contemporary image preference. Feminine-typed females liked classic image most among Korean female subjects. 6. Korean males especially prefered luxurious image least. Korean females contemporary most, American males sexy most, American females fashionable most among four subject groups. That is, differences on clothing image preferences were found according to sex role identity, sex, and culture.

Stimulatory effects of epidermal growth factor (EGF) and transforming growth $factor-{\alpha}$($TGF-{\alpha}$) on the growth of squamous cancer cell lines established from human oral cancer tissue with moderate differentiation were studied in vitro. After culturing in serum-free media for 24 hours, growth factors-EGF only, $TGF-{\alpha}$ only and EGF, $TGF-{\alpha}$ together-were added to the media and numbers of cells were analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and compared with the control at 96, 144 hours. Each of EGF and $TGF-{\alpha}$ showed statistically significant stimulatory effects on the growth of cells respectively. Dose-dependent relationship of the stimulatory effects were not clearly demonstrated. The effects of EGF were higher than those of $TGF-{\alpha}$ and combinative administration showed higher effects than those of single uses. In conclusion, EGF may play an important and major role in differentiation and growth of human oral squamous cancer cells. $TGF-{\alpha}$, produced from cells activated by EGF, also can stimulate the cell growth and could be an alternative ligand for EGF receptor.

This study examines the impact of corporate tax, a fiscal measure along with trade liberalization and research and development on total factor productivity for a panel of 153 industrial firms listed on the Pakistan Stock Exchange over the period 1997-2017. For empirical analysis, we employ the system generalized method of moment estimator. In the first step, we estimate industrial production function and the results reveal that raw material, industrial labour force and energy play vital role in enhancing industrial production. Whereas, industrial capital exerts negative impact on industrial output. We also measured total factor productivity using the production elasticities. In the second step, we examine the impact of corporate tax, trade liberalization and research and development on total factor productivity. The results indicate that higher level of corporate tax exerts negative impact on total factor productivity. The findings reveal that higher corporate taxation discourages industrial firms to undertake research and development thereby exerting adverse impact on total factor productivity of firms. The impact of trade liberalization proxied by average tariff is positive while customs duty and sales tax negatively impact firm-level total factor productivity. These findings provide useful insights for managers, investors and policy makers in Pakistan.

The purpose of this study was to exam the effects of gender-role identity on adolescents' self esteem, clothing behaviors and favorite clothing image, focusing on analysis by adolescent' sex and age variable. The research method was survey and the subjects were 447 male and female adolescents in Daejeon, Korea. The questionnaire consisted of 4 measurement instruments (gender-role identity, self-esteem, clothing behaviors, and favorite clothing image) and subject' demographic attributions. The data were analyzed by factor analysis, $X^2$ test, t-test, ANOVA(analysis of variance), Duncan's multiple range test, and Pearson's correlation analysis, using SPSS program. The results are as follows. First, adolescents' gender-role identity and self- esteem were different by age rather than sex. Middle school students were represented by undifferentiated type while high school students were represented by androgynous type, and high school students had higher self-esteem than middle school students. Second, four factors emerged on clothing behaviors(clothing interest & psychological dependence, ostentation, conformity, and comfort), and favorite clothing image(characteristic, neat, active, and romantic image). Third, gender-role identity had important effects on self esteem; androgynous type had higher self esteem than other gender-role identity type. Forth, self-esteem had significant relationship with clothing behaviors and favorite clothing image, and these relationships were different by adolescent' sex and age variable. Fifth, gender-role identity had important effects on clothing behaviors; and rogynous type had more clothing interest, ostentation and comfort than any other gender-role identity type. Sixth, gender-role identity had important effects on favorite clothing images; androgynous type pursued more various clothing images than any other gender-role identity type.

Background: Platelet-activating factor (PAF) induces nuclear factor $(NF)-{\kappa}B$ activation and angiogenesis and increases tumor growth and pulmonary tumor metastasis in vivo. The role of $NF-{\kappa}B$ activation in PAF-induced angiogenesis in a mouse model of Matrigel implantation, and in PAF-mediated pulmonary tumor metastasis were investigated. Methods: Angiogenesis using Matrigel and experimental pulmonary tumor metastasis were tested in a mouse model. Electrophoretic mobility shift assay was done for the assessment of $NF-{\kappa}B$ translocation to the nucleus. Expression of angiogenic factors, such as tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\alpha}$, basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF) were tested by RT-PCR and ELISA. Results: PAF induced a dose- and time-dependent angiogenic response. PAF-induced angiogenesis was significantly blocked by PAF antagonist, CV6209, and inhibitors of $NF-{\kappa}B$ expression or action, including antisense oligonucleotides to p65 subunit of $NF-{\kappa}B$ (p65 AS) and antioxidants such as ${\alpha}$-tocopherol and N-acetyl-L-cysteine. In vitro, PAF activated the transcription factor, $NF-{\kappa}B$ and induced mRNA expression of $TNF-{\alpha}$, $IL-1{\alpha}$, bFGF, VEGF, and its receptor, KDR. The PAF-induced expression of the above mentioned factors was inhibited by p65 AS or antioxidants. Also, protein synthesis of VEGF was increased by PAF and inhibited by p65 AS or antioxidants. The angiogenic effect of PAF was blocked when anti-VEGF antibodies was treated or antibodies against $TNF-{\alpha}$, $IL-1{\alpha}$, and bFGF was co-administrated, but not by antibodies against $TNF-{\alpha}$, $IL-1{\alpha}$, and bFGF each alone. PAF-augmented pulmonary tumor metastasis was inhibited by p65 AS or antioxidants. Conclusion: These data indicate that PAF increases angiogenesis and pulmonary tumor metastasis through $NF-{\kappa}B$ activation and expression of $NF-{\kappa}B$-dependent angiogenic factors.
