'Sentence posing' is newly given in the third through sixth grade mathematics textbooks of the revised 2007 curriculum to confirm students' understanding on mathematical concepts of definitions. In this paper, we discuss the role of the sentence posing in the third grade mathematics textbooks on the basis of the problems occurred in third graders' sentence posing activities. Overall, it turned out that the role of the sentence posing was somewhat restrictive. Hence the sentence posing needs to be applied to check whether students can properly use the definitions in real life situations. In addition, it is necessary to employ the present role of the sentence posing to confirm students' understanding on mathematical concepts of definitions selectively according to the concepts of definitions.

The purpose of this study is to examine the perception of librarians on the role of public libraries related to disasters. For this purpose, the study conducted an online survey for librarian. The survey is composed of 34 questions, including the questions asking librarians' perceptions about the roles of public libraries related to the disasters derived from literature review. The research results are as follows; First, although librarians were not well aware of the roles of public libraries related to disasters, they generally supported the necessity of the role and evaluated the benefits of the role highly. Second, librarians recognized the necessity of the role of the library in the following order of importance; psycho-emotional support for citizens who have experienced disasters; cooperation with disaster support agencies; disaster shelter; disaster information service; archiving disaster experiences of residents; outreach services; community support. Third, librarians recognized that psycho-emotional support services for residents suffering from disasters were the most necessary and beneficial to residents. Fourth, librarians' perceptions of disaster-related library roles changed based on their position and the type of library they belong to. On the basis of these results, the research discussed and suggested what roles each public library should play and what services it should plan, and how it should be implemented during the disaster.

The purposes of this study were: (a) to examine the relationship between parental/occupational role reconstruction and psychological well-being in middle and old age, (b) to investigate the psychological factors to affect parental/occupational roles reconstruction. The role reconstruction was measured as the extent to obsess with parental and occupational role in transition. Mail survey was conducted on 378 Japanese married men and women in ages between 50 and 69. As results, the hypothetical pathway was identified in women as follows. The obsession with parental and occupational roles raised parental and occupational role loss anxiety. And both of role loss anxiety lower psychological well-being. For men, obsessed with the occupational role was significantly influenced by autonomy, gender role attitude, social support network. For women, gender role attitude significantly influenced on occupational and parental role obsession, and social support networks had significant impact on parental role obsession. Results of this study were discussed in terms of the importance of role reconstruction in middle and old age, gender difference in role reconstruction according to gender role socialization.

This study aimed at analyzing visual materials included in school science textbooks, specifically the textbooks for first semester courses of 3rd to 6th graders. The purpose was to provide directions for future textbooks by understanding the functions of the images in both pedagogical and social perspectives as well. The study was conducted by investigating the types, roles and socio-semiotic features of the images in science textbooks. The results were as follows. Firstly, the most used types of images in 2007 curriculum textbooks were photographs and drawn pictures. Uses of other visual aids than above were extremely rare. It was also found that as the educational level rises, the use of images for decorative functions drastically declined. The majority of the images were used in providing supplementary explanations or examples. This implies that the images effectively play the role of helping science education. In addition, more use of worksheets images was found, indicating that as educational level increases, students participate more actively in research sessions or data analysis. In socio-semiotic perspective, visual images showed high accessibility to students in 'Type of visual image', 'Function of visual image', 'Distance of shot', 'Horizontal angle of shot', 'Color moduation'. It was implied that there will a close correlation between the type, role and the socio-semiotic characteristics of visual images in textbooks. For example, photograph-type visuals were mostly used as supplementary references. And when applying the socio-semiotic analysis to photograph-type visuals, they showed 'real type', 'narrative-metaphor type', and 'shadow effect' among socio-semiotic features. Such correlations implied that knowing the type of the visual image may help determining the role of the image in the textbook to some extent, and also corresponding socio-semiotic characteristics. As a result, it was possible to infer how accessible certain visual images are to students. The above results have implications for the effective use of visual images in future textbooks.

This study was carried out to confirm a convergent research pattern and researchers' role in stem cell sector by social network analysis. Articles were extracted from 1996 to 2012 in PubMed, 515 authors of 270 embryonic stem cell and induced pluripotent stem cell articles and 1,515 authors of 580 adult stem cell and mesenchymal stem cell articles. Degree(D) and betweenness(B) centrality was measured and co-author network was generated for researcher's role. As a result, Core researcher and Intermediary researcher was identified in co-author network. Core researcher had high D. centrality, otherwise high B. centrality or not. Intermediary researcher for convergent research had high B. centrality and low D. centrality. Conclusively, co-author network will be used as objective data not only to find core researchers in subject area for improving achievement but also to select experts for research project evaluation.

This research attempts to carry an empirical study on women leaders' gender-related leadership styles and relationship between job satisfaction and organizational commitment. For these purpose, this study built two hypotheses based on literature review and tested them using the survey method of 1,172 female workers in sales departments of the K company. The results of this study show that both the androgynous gender role and the masculine gender role are superior to the feminine gender role in employees' job satisfaction and organizational commitment level. But there isn't significant level difference in job satisfaction and organizational commitment between androgynous gender role and the masculine gender role.

Recently collaboration network is generated to find out experts in their field as potential collaborators in health care sector. In this paper, the co-author network of a National Cancer Center researcher was generated for identifying each researcher's role and collaborative research pattern. The co-author network of 2,437 authors was extracted from 1,194 SCI(E) publications from 2000 to 2010 and author's role was analyzed by author's centrality value. Centrality reflecting only the number of papers and centrality weighted by the paper number, impact factor, and authorship contribution was evaluated. On the comparison with simple degree centrality value and the weighted degree centrality, difference of value was statistically significant(t=11.66, p=0.00). Co-author network considering various variables of the paper provides more objective figure of researcher's role. This suggests that co-author network could be more effective in identifying potential collaborators.

한국어 자음에 대한 생리적인 분류는 조음점 및 조음발법에 따라 다시 세분화할 수 있는데 그중에서 조음발법에 따라 파열음, 마찰음, 파찰음 및 비음들 여러가지로 분류할 수 있다. 그중 특히 파열음은 그 개방하는 방법에 따라 연음(lenis), 경음(glottalized) 및 기식음(aspirated)등으로 구분하는데 이러한 각음을 육안으로 확인하면 모음이 발성되기 위한 성대진동이 있기전의 자음을 위한 성대의 운동의 현상을 보면 기식음에서는 성대열림이 가장 크고 연음에서도 열림이 크지만 기식음보다는 적고 경음에서는 성대의 열림이 가장 작았다. 이러한 현상은 후두내시경에 의해 쉽게 확인할 수 있었는데 이것을 과학적으로 규명하기 위해서는 여러연구에 의해 가능하나 흔히 후두근전도 검사에 의한 성대내전근과 외전근의 역할의 차이를 비교함으로서 가능해지리라 예상되어 본 연구를 시행하였다. 사용된 문형 또는 단어는 한가지를 제외하고는 모두 의미있는 단어를 사용하였으며 EMG recording을 위해 사용된 근육은 후두내전근인 Vocalis muscle과 후두외전근인 Posterior cricoarytenoid muscle이 사용되었고 전기신호는 computer data processing system에 의해 분석되어졌다. 결과는 내시경에 의한 성대열림의 거리측정 결과를 분석함과 동시에 후두내근에 대한 근전도검사에 의한 분석을 토대로 하였으며 이를 간단히 설명하면 이제까지 많은 사람들은 한국어 자음에 대한 각각의 특징적인 현상들을 주로 성대내전근의 역할에 의해 규명하였으나 본 결과로는 성대내전근의 역할도 중요하지만 성대외전근의 역할 또한 상호 연관성을 가지면서 매우 중요한 역할을 한다는 점이다.for the Isotropic plates can be used.
