  • SiCl$_4$/CH$_4$/H$_2$계를 사용한 플라즈마 화학증착법(PECVD)으로 실리콘(100) 기판 위에 3C-SiC막을 117$0^{\circ}C$~1335$^{\circ}C$의 온도범위에서 증착하였다. 증착온도, 유입가스비, R$_{x}$ [=CH$_4$/(CH$_4$+H$_2$)], 그리고 r.f. power를 변화시켜 증착막의 결정성에 대해 검토하였다. Thermal CVD에 비해 PECVD법은 박막의 증착속도를 향상시켰다. 증착된 3C-SiC은 (111) 면으로 최대의 우선배향성을 지님을 알 수 있었다. 실리콘 기판 위의 3C-SiC막의 결정성은 R$_{x}$값에 의존하였으며, R$_{x}$가 감소할수록 결정성이 더욱 향상되었다. Free Si가 3C-SiC막과 함께 증착되었으나, 증착온도와 r.f power가 증가함에 따라 free Si의 함량은 감소하였다. 증착온도 127$0^{\circ}C$, 유입가스비 R$_{x}$=0.04, r.f. power가 60W에서 비교적 결정성을 가진 3C-SiC막을 얻을 수 있었다.

  • Purpose: The objective of this study was to analyse the content of health-textbooks in elementary school in order to offer the basic data required for development or revision of health-textbook for elementary school. Methods: This study was methodological study of the content of health-textbooks. The study sample consisted of 10 health-textbooks of elementary school which were edited in 2009~2010. The components of contents divides into holistic analysis and specific areas. Results: One textbook was no introductory remarks and 2 textbooks were no preface. The health-textbooks consisted of 7 areas and were comprehensive for school education. The proportion of each was different in 10 textbooks. Sexuality and health was accounted for the largest portion of the seven areas in both the fifth and sixth grade. However, given that the mortality rate for the child's safety accidents is higher than in developed countries, the proportion of accident prevention and first aid can be relatively weak area. Conclusion: It is essential that health-textbooks empower schoolers to make healthy decisions through the promotion of useful life skills that provide a more integrated concept of health. Therefore, there is a need for approaches to health textbook to integrate more values of health.

  • To study the characteristics and processing of Kochujang which is rapidly fermented by commercial enzymes, three kinds of Kochujang(KP-FA, KP-FN, and KP-BN) using commercial proteases and one Kochujang(KM) using Meju were prepared and their qualities investigated. There were only small differences in pH and acidity between each Kochujang. The moisture contents were high tendency in the three kinds of Kochujangs using the commercial proteases at 20 days of fermentation. Reducing sugars had a tendency to decrease during the fermentation in the Kochujangs using the proteases. During the first half of fermentation, the Kochujangs made with proteases showed higher amino nitrogen contents than the Kochujang(KM) made using Meju. Acidic protease activity was high in KP-FA at 20 days of fermentation and neutral protease activity was high in KP-FN and KP-BN at the beginning of fermentation. The Kochujangs made using the proteases, through 20 days of fermentation, obtained high preference in the sensory evaluation for color, texture, and overall acceptability. However, the hot taste was stronger in these Kochujangs during the fermentation.

  • This article analyzes the record structure, content designation, and the content of UNIMARC, USMARC, and KORMARC formats for authorities, through the comparative investigation, Structure and content designation are almost same with those of the bibliographic formats, being based on those of ISO 2709. The data fields of USMARC and KORMARC are divided into blocks based on the traditional authority card formats, and those of UNIMARC are divided into functional blocks based on the GARE. Record contents of the formers in the fixed-length fields include more elements on the selectioa status and scope of the heading, and those related to the series. And those of the later include more elements for the international exchange. Based on the analysis of the variable fields, it is recommended that KORMARC should include an additional subfield, say $(\blacktriangledown\;j)$ for the processing of the Hanja(Chinese character) data and add the separate classification fields for series.

  • As affective barriers to library and information use, library anxiety(Mellon, 1986) has been studied in reference/information services and bibliographic instructions. The paper revisits Mellon's theory of library anxiety and Bostick's(1992) Library Anxiety Scale(LAS) in the digital library environment. In particular, this study attempts to address the inadequacy of the continued applications of LAS in the digital library environment, although the scale has been used unquestionably as the instrument measuring library anxiety. This contention was substantiated by three service trends in digital libraries(i.e., digital reference services, remote access, and transition from bibliographic instructions to information literacy) and by re-analyses of published library anxiety research papers in recent years. This study addresses the need for scale development that could measure anxieties of digital library users. It also suggests Information Literacy Anxiety Scale(ILAS) as a direction for the new scale.

  • The KERIS Union Catalog is the largest bibliographic database in Korea. It has over 5.7 million bibliographic records and at present 330 university libraries are participating in shared cataloging services. The database, however, includes various errors and a large number of duplicate data because separate databases from many university libraries were merged without proper quality control in a short period. This study intends to find error data types by analyzing dissertation bibliographic data. The results show that error data are mainly caused by input errors, and the mistakes in using MARC formats and cataloging rules.

  • Social capital theory provides a robust framework for analyzing economic well being. The purpose of this study was to investigate the effects of social capital on the economic satisfaction of retirees in Korea. The data from the first wave of KLoSA(Korean Longitudinal Study of Aging) were used(n=1,628). SPSS 12.0 was used for descriptive statistics and multiple regression analysis. The major findings were as follows: First, after controlling for gender, age, region, housing tenure, and personal income, the social capital of the retirees, including cognitive social capital(trust and reciprocity) and structural social capital(emotional and economic familial support, and a well-developed social network), contributes to increases in their economic well-being. Second, the degree of effect social capital has on well-being varied by gender and age; the effect was also different according to gender, regardless of the person's age. These empirical results provide a basis for the institution of policies that help bolster economic wellbeing for retirees by creating conditions that increase social capital in this group.
