  • (PbS)$_{1-x}$ -(CuS)$_{x}$ thin films(x=0, 0.5, 1) were grown on glass substrates by using a chemical bath deposition method. The molecular ratio of Pb to Cu for the PbS-CuS thin films(x=0.5) was measured about 7:3 by using EDX and XRF. The resistivity of non-annealed (PbS)$_{1-x}$ -(CuS)$_{x}$ thin films was about 10 $\Omega$ . cm. However, after annealing, the resistivity of PbS showed a little change, while PbS-CuS and CuS significantly decreased in the range of 0.002 to 0.005$\Omega$.cm. PbS was p-type and CuS was n-type.-type.

  • This study investigated the relations among a child's emotionality, mother's depression and parenting behaviors in predicting a child's happiness. Participants were 384 children(175 boys, 209 girls) and their mothers. The teachers completed the rating scale to measure a child's happiness. A child's emotionality, mother's depression and parenting behaviors were assessed by a mother-reported questionnaire. The collected data was analyzed using descriptive statistics, correlations, and hierarchical multiple regressions. Results showed that child's emotionality was negatively related to their happiness. Mother's depression had a negative relation to child's happiness. Mother's warmth-encouragement, overprotection-permission, and reject-nonintervention was significantly related to a child's happiness. Hierarchical regression analysis indicated that the interaction of child's emotionality and mother's reject-nonintervention predicted child's happiness. Child's emotionality, whose mother demonstrated a higher level of reject-nonintervention, was associated significantly with happiness. In addition, the association between mother's depression and child's happiness was mediated by mother's warmth-encouragement and reject-nonintervention. Results suggest the importance of mother's role in the context of intervention planning for child's happiness.

  • The purpose of this study was to examine the relationships between child’s temperament and behavior problem according to child’s sex. The subjects for this study were children’s mothers of 2nd grade selected from elementary schools in Busan. Han, Sae-Young’s questionnaires(1996) on child’s temperament and Kim, Min-Kyung’s questionnaires(1998) on child’s behavior problem were used. Statistical techniques such as t-test, Pearson’s correlation, multiple regression, canonical were used. The results were as follows : (1) According to sex, there were no significant differences in child’s temperament. But there were significant differences in child’s behavior problem. The boys got higher scores than girls in hyperactive/distractive behavior and in hostile/aggressive behavior. (2) There were significant correlations between child’s emotionality and hyperactive/distractive behavior, between child’s emotionality and anxious/fearful behavior, between child’s emotionality and hostile/ aggressive behavior, and between child’s activity and hyperactive/distractive behavior. (3) The predicted variables for child’s hyperactive/distractive behavior were emotionality and activity. The predicted variable for chid’s anxious/fearful behavior and hostile/aggressive behavior was emotionality. (4) Among three dimensions of boy’s temperament, the effective variable was emotionality. And among three dimensions of boy’s behavior problem were anxious/fearful behavior and hostile/aggressive behavior. Among three dimensions of girl’s temperament, the effective variable was emotionality. And among three dimensions of girl’s problem behavior was anxious/fearful behavior. Implications of this study were discussed in terms of child’s temperament and behavior problem.

  • The ZnS/CdS thin films were made using 99.99% ZnS and CdS(Aldrich) powders in $7{\times}10^{-6}torr$. The ZnS layer was coated over the CdS layer on an AlOx membrane within a vacuum, at the average speed of $1{\AA}/sec$. After studying the ZnS/CdS and CdS thin films(both with the dimensions of 2.52nm), using fluorescence spectroscopy and comparing the respective results together, we found that although both of the resulting spectra peaked at 390nm, the ZnS/CdS thin films showed a narrower peak, and a higher intensity of photoluminescence than the CdS thin films. The particles of ZnS/CdS thin films also proved to be more homogeneous in size. In addition, the ZnS layer acted as a protective layer. Also, after studying the spectra of ZnS/CdS thin films taken 30 days after their preparation, we found no signs of aging. These results were verified through the scanning electron microscopy(SEM), EDX analysis, thin film X-ray diffraction, and luminescence spectroscopy.

  • Objective: The purpose of this study is to explain in detail the factors of the father's play interaction that predict children's adaptive emotional regulation. This study examined the moderated mediation effect of a father's rough-and-tough play toward a child's emotional expressiveness and the father's play participation attitude on the child's adaptive emotional regulation. Methods: The study participants included 309 fathers of children aged from 3 to 5 years. Data were analyzed using models of the PROCESS Macro. Results: As a result of this research, the relationship of the father's rough-and-tough play with the child's adaptive emotional regulation was that this was indeed mediated by the child's negative emotional expressiveness. Additionally, the father's responsive and fun play attitude moderated the relationship between the father's rough-and-tough play and the child's adaptive emotional regulation. Further, the father's responsive and fun play attitude according to level had a moderated mediation effect. Conclusion/Implications: These results are meaningful in that they derives a mechanism for why and how a father's rough-and-tough play affects children's adaptive emotional regulation.

  • The purpose of this research is to analyze the relationship between the inspirations and designs of Dries Van Noten's Men's collections from 1992 S/S to 2014 F/W. The specific questions of this research are as follows: what are the important design features of the Dries Van Noten's Mixed collections from 1985 S/S to 1991 F/W? What are 'the roots of inspiration' of Dries Van Noten's Men's collections from 1992 S/S to 2014 F/W, and what are the aesthetic criterions of Noten's works? How can the roots of inspiration be categorized and what are its features? How did these roots of inspiration influence the Noten's designs? The paper is a reference of how ideas turn to practical works, and what the relationship between inspiration and design. Researchers utilized a qualitative research method providing a systematic review of the previous studies by analyzing the content. To conclude, roots of inspiration of Dries Van Noten's Men's collections can be classified into nine categories: 'Interpretation', 'Ethnic', 'Multiple Contents', 'Subculture', 'Region', 'Artist', 'Fashion Item', 'Sports', and 'New Trend'. Through the roots of inspiration, sensibility of Belgium, England, Italy, French chic, inquiry of ethnic, artist, sports, the neuter gender image, 1950's, 1960's & 1970's trend & style of street fashion, elegance for men, romanticism, zoot, rock 'n' roll, teddy boy, mods, punk, new romantic and 19th century's Anglo-Saxon style are extracted and applied to the designs through cross impact. The identity of Dries Van Noten's Men's collections are cross culture contents and harmony of the old generation and new generation.
