The purpose of this study was to examine and compare the perceptions of mothers about the Nuri curriculum for 5-year olds. The subjects were 382 mothers whose 3-5-year old children went to kindergartens (192 mothers) and daycare centers (190 mothers). The findings were as follows: First, the majority of the mothers knew that the Nuri curriculum for 5-year olds started to be carried out in 2012, but many of them weren't told about the details at all. Second, the mothers considered the Nuri curriculum necessary, and were roughly satisfied with the ongoing Nuri curriculum for 5-year olds. Third, there was no difference in the mothers' perceptions of environmental factors required for the Nuri curriculum. Fourth, the mothers whose children went to kindergartens chose warm and enthusiastic character as important quality of teachers. The mothers whose children went to daycare centers chose friendly and caring character as important qualities of teachers. Fifth, the mothers perceived that the Nuri curriculum was relatively useful for the qualitative improvement of early childhood education and childcare. Sixth, the majority of the mothers didn't have their children transfer to another early childhood education institution after the Nuri curriculum for 5-year olds was carried out.

Leaf morphology was examined for Prunus species from Jeju Island. Analyzed were the leaf blade length, petiole length, width of blade, number of veins and angle of the base to the mid-vein as quantitative characters and the distribution of trichome, position of glandsand leaf features qualitative characters. A total of 25 OTU were phenetically analyzed by UPGMA. The resuling phenograms slightly differ from the currently recognized taxonomic system in two points. Prunus mume was clustered with P. padus and P. buergeriana. Prunu spendula and P. yedoensis were separated from the cluster of P. jaamasakura, P. speciosa, P. sargentii and P. jamasakura var. quelpaertensis. Except for the members of subgenus Cerasus, subgenera Padus (P. buergeriana and P. padus), Microcerasus (P. japonica) and Amygdalus were well defined. Some morphological characters of leaves such as the ratio of blade length to width, the length of blade to petiole, number of veins, the distance between the gland and base, the angle of base to mid-vein, and the distribution of trichome were useful as diagnostic features for Prunus from Jeju Island.

There have been reports that the "jeongcho (定礎)" letters of the foundation stone at the historical site No. 280 of the "Main Building of the Bank of Korea in Seoul" were written by Prince Ito Hirobumi (伊藤博文), the first Resident-General of Japan in Korea. An on-site investigation by an advisory group consisting of three experts in calligraphy; revealed that the two characters of '定礎' inscribed on the foundation stone are the characteristics of Ito Hirobumi's handwriting, judging from the writing style and habits observed in the collections of the Central Library of Hamamatsu City, Japan. It was reported that his writing was confirmed by the experts, but no basis was provided. To provide more objective and quantitative supporting data, rather than qualitative judgment based on feeling, it is necessary to present the basis for judgment through quantitative image comparison results through image analysis. In this paper, using image analysis software, Ito Hirobumi's calligraphy writing and the inscribed characters of the foundation stone were compared and analyzed to confirm the contents of the press release. The character comparison process and character area measurement results are a good example showing that if objective judgment basis data are needed in a similar situation, an objective judgment basis can be prepared through quantification using image analysis.

Lettuce is an important annual leafy vegetable and bitterness is its potent flavor character. Lettuce germplasm differ their phenotypic characters and sesquiterpene lactones (SLs) contents which are important for consumer's acceptance. This study was carried out to evaluate the phenotypic characters and SLs contents in one hundred lettuce germplasm in Jeonju, Korea. Twenty-three agro-morphological (16 qualitative and 7 quantitative) traits and two SLs (lactucin and lactucopicrin) contents were studied in these germplasm. Germplasm exhibited the variation in qualitative and quantitative characters. Average plant weight was 423.9 g with a range from 116.0 to 905.0 g. Lactucin content was varied from 19.7 (IT 294226) to $194.4{\mu}g/g$ (IT 294298) with an average concentration of $84.7{\mu}g/g$. Lactucopicrin ranged from 82.5 (IT 300134) to $2228.6{\mu}g/g$ (IT 294210) with an average concentration of $586.3{\mu}g/g$. Total SLs content was ranged from 120.1 (IT 300134) to 2286.6 (IT 294210)${\mu}g/g$ with the average concentration of $671.0{\mu}g/g$. Significant ($p{\leq}0.05$) differences were found between crisp head and butter head germplasm for lactucin, lactucopicrin and total SLs content. Crisp head germplasm revealed the highest average lactucin ($112.9{\mu}g/g$), lactucopicrin ($734.8{\mu}g/g$) and total SLs content ($847.7{\mu}g/g$). Crisp head and leafy type germplasm exhibited more total SLs content (847.7 and $744.7{\mu}g/g$, respectively) than cos ($524.9{\mu}g/g$) and butter head type ($519.4{\mu}g/g$). Principal component analyses of the quantitative traits indicated that the first principal component axis accounted more than 91% of the total variation. This study revealed the ample genetic variation in the agro-morphological traits and SLs contents to support the selection for improved lettuce varieties.

The paper holds its purpose to analyze the descriptive function and meaning of first person animation which the focalizer, character, and all narrators are indicated as 'I', For the purpose, the following was reviewed; the relation between 'I' as child memorizing the days of childhood as adult and the current 'I' as adult, and the aesthetic effect of experience and sense of the child on the audience reading the narration. The retrospective narrating situation of the adult narrator brings descriptive effect which comes from 'the tension between the experiencing self (self as child) and the narrative self (self as adult). The works focus on the content of child experience through the confession of the adult narrator, but the view of the adult always heading towards 'the present'. That is, the aesthetics contained by the first person narrator is related to endless arousal of the values of hidden and forgotten things. In addition, the descriptive method of child focalizer as 'the subject of experience' brings qualitative change which enables reasoning of the subject as itself, which is free from the view tamed by rational system. Becoming an adult, the lost ability of mimesis brings qualitative change by meeting with the generality of childhood sense. Therefore, it can be known that the meaning the narrator contains in the first person narrator condition of animation links with the degree of aesthetic completion of the work, but also, it is a highly strategic descriptive device which determinately affects even the acceptance of audiences regarding the work.

In seven species of Korean Asarum, 44 qualitative and 28 quantitative characters were reviewed taxonomically. Among 44 qualitative characters observed in vegetative and reproductive organs, the states of 27 characters were common in all the seven species. Among 28 quantitative characters, five characters have the same values in all the seven species; the number of cataphyll (2-4), leaf (2), calyx lobe (5), stamen (12) and pistil (6). White spots on adaxial surface of leaf (effectively) distinguished A. maculatum and A. versicolor from the other species. Many long soft hairs on abaxial surface of leaf distinguished A. mandshuricum from other species with short hairs. The glandular hairs on inner surface of calyx tube were divided into 2 types, reflecting the taxonomic relationships between the species: Type 1 has non-stalked glandular hairs (A. maculatum, A. sieboldii and A. sp.), and Type 2 has stalked glandular hairs (A. patens, A. versicolor, A. mandshuricum and A. misandrum). The length, shape, colour of calyx lobe and the extent to which the calyx lobe recurves, as well as the diameter and colour of calyx tube throat, were confirmed to be taxonomically valuable. In the case of glandular hair density on the surface of calyx lobe, A. patens with low density and A. sp. with high density were clearly distinct from all the other species with intermediate hair density. Meanwhile, the stylar protuberance length of A. patens (2.9-3.3 mm) was strikingly different from other species (1.4-2.5 mm). Additionally, further examination of the identities of A. yeonbyeonense and A. yeonbyeonense var. viridiluteolum is required.
