  • The subject specialization room will be able to support university library users who are inclined to use the general reading room. This study is the research of the area planning for university library's subject specialization room. For the evaluation, 431 users from 15 university libraries in 14 universities located across Seoul were surveyed. Statistical analysis was performed using SPSS. Frequency, percentage, mean, t-test, f-test were used. Results of the study are as follow. Subject specialization rooms in university libraries can be classified via the analysis of spatial characteristics. According to the area ratio of data space and reading space in a subject specialization room, the subject room can be separated into data-loaning and data-reading types. Old libraries are more likely to be data-loaning types, where reading room is small and there are a lot of bookshelves. The annual increase in library collections causes space for bookshelves to decrease. As a result, space for reading has been gradually transformed into space for stacking data. It is necessary to introduce ways to maintain enough space for both reading and stacking data. One way includes movable compact shelving, which can partially replace existing fixed shelves.

  • The purpose of this study was to investigate the relationship between knowledge of breast feeding and practice of feeding pattern. A sample of 117 mothers who have the babies between age from 1 month to 12 months were selected from one university hospital and one public heath care center in J city. The data were collected with the questionnaire during the period from the January. 5, 2002 through January. 30, 2002. Analysis was done by using frequency, percentage, t-test, analysis of variance, and scheffe test. The results of this study can be summarized as follows. Comparision of the method of feeding by general characters. Income state, rearing (p=.019), rearing supporters(p=.026), infant age(p=.03) have shown significant difference as the variables affecting Breast practice rate. Breastfeeding rate were 24.8%, mixedfeeding type, 14.5%, milkfeeding type, 60.7%. The mean of knowledge on breastfeeding by feeding patterns were the highest in the group of breastfeeding. There was statistical significance between the group of breast feeding and milkfeeding(p=.000). In the conclusion, this study revealed that knowledge of breastfeeding promoted practice of breastfeeding. Therefore, to promote practice of breastfeeding, it is necessary that nurses provide adequate information about knowledge of breastfeeding.

  • We have investigated the dynamical stability of the proposed companions orbiting the Algol type short-period eclipsing binary SW Lyncis (Kim et al. 2010). The two candidate companions are of stellar to substellar nature, and were inferred from timing measurements of the system's primary and secondary eclipses. We applied well-tested numerical techniques to accurately integrate the orbits of the two companions and to test for chaotic dynamical behavior. We carried out the stability analysis within a systematic parameter survey varying both the geometries and orientation of the orbits of the companions, as well as their masses. In all our numerical integrations we found that the proposed SW Lyn multi-body system is highly unstable on time-scales on the order of 1000 years. Our results cast doubt on the interpretation that the timing variations are caused by two companions. This work demonstrates that a straightforward dynamical analysis can help to test whether a best-fit companion-based model is a physically viable explanation for measured eclipse timing variations. We conclude that dynamical considerations reveal that the proposed SW Lyncis multi-body system most likely does not exist or the companions have significantly different orbital properties from those conjectured in Kim et al. (2010).

  • The purposes of this study were to test differences in conflict-resolving strategies and emotional intelligence based on children's peer status, and to verify the discriminance of conflict-resolving strategies and emotional intelligence for peer status. 58 popular children and 52 rejected children from 4 elementary school were selected, and the data were analyzed with independent sample t-test and discriminant analysis. The research findings are as follows: First, negotiation- and cooperation-strategies (sub-factors of conflict-resolving strategy) and emotional intelligence showed statistically significant differences between popular children and rejected children, while other sub-factors of conflict-resolving strategy and sub-factors of emotional intelligence showed indifference between them. Second, negotiation- and cooperation-strategies among 4 sub-factors of conflict-resolving strategy and 5 sub-factors of emotional intelligence were the most discriminant predictors for children's peer status. The results suggest systematic teacher training and program for the rejected children's improvement of negotiation- and cooperation-strategies in their peer relations.
