  • Cooperation between school libraries and public libraries is one of strategies to use the libraries'resources effectively and foster an educational role of librarians by providing good services to children and young adults. According to analysis results of the questionnaire on their cooperation, they sympathize necessary of cooperation between school libraries and public libraries and consider programs and materials as the most necessary part of mutual cooperation. They recognize that lack of awareness and attention obstructs their coordination in common. The teacher librarians promote the programs and services for children and young people of the public libraries, the public librarians also introduce their programs to the school libraries and discuss purchasing and providing educational materials with the teacher librarians. Finally, they assist that assignment of professional workforce and network operation are necessary to improve inter library collaboration.

  • This study aims to compare and analyze the environment of natural parks and Ulleung island using the plant taxa classified by five degrees based on their distributional ranges. The scores differentially given based on the importance of each degree; taxa belonging to the fifth degree are given to 20 scores each, fourth 10, third 5, second 3.3, and first 2.5, respectively. The total assessed scores were ranked as Mt. Halla, Seorak, Jiri, Deokyu, Is. Ulleung, Mt. Sobaek, Odae, Palgong, Chink, Taebaek, Songni, Juwang, Gaya, Duryun, Gaeryong, Bukhan, Naebyeon, Worak, Naejang, Cheongryang, Naeyeon, Myeongii, Jokye, Mudeung, Wolchul, Geumo, Juheul, Biseul, Hwangmae, Jangan, Seonun, Moak, Seonam, Chilgap, and Gibaek, in order, respectively. It is suggested that the natural environments assessing more than 1,000 of total scores such as Mt. Halla and Mt. Deokyu are regarded as the most excellent ones, and those between 700 to 1,000 of total scores such as Is. Ulleung and Mt. Odae are regarded as relatively excellent ones. Natural parks scored between 500 to 700 such as Mt. Palgong and Mt. Gaya are regarded as good ones and parks scored between 300 to 500 such as Mt. Duryun and Mt. Mudeung are regarded as normal ones. The area assessed less than 300 of total scores such as Mt. Wolchul and Mt. Gibaek are regarded as the most inferior ones. The total scores of the national parks are generally higher than those of the provincial and county parks. In addition, Ulleung island has a total of 882.9 scores. Therefore, according to the IUCN the Ulleung island should be included in the criterion of the preservative model of natural ecosystem, suggested by Ministry of Environment. At the same time, Ulleung island should be included to the superior model of natural scenery resources by its uniqueness of topography, geography and natural environments. Ulleung island is assessed as having relatively excellent natural environments as compared with other national parks, suggesting that the island should be designated as a new national park.

  • Kale (Brassica oleracea var. acephala) is one of the most frequently consumed leafy vegetables globally, as it contains numerous nutrients; essential amino acids, phenolics, vitamins, and minerals, and is particularly rich in glucosinolates. However, the differences in the biosynthesis of glucosinolates and related gene expression among kale cultivars has been poorly reported. In this study, we investigated glucosinolates profile and content in three different kale cultivars, including green ('Man-Choo' and 'Mat-Jjang') and red kale ('Red-Curled') cultivars grown in a vertical farm, using transcriptomic and metabolomic analyses. The growth and development of the green kale cultivars were higher than those of the red kale cultivar at 6 weeks after cultivation. High-performance liquid chromatography (HPLC) analysis revealed five glucosinolates in the 'Man-Choo' cultivar, and four glucosinolates in the 'Mat-Jjang' and 'Red-Curled' cultivars. Glucobrassicin was the most predominant glucosinolate followed by gluconastrutiin in all the cultivars. In contrast, other glucosinolates were highly dependent to the genotypes. The highest total glucosinolates was found in the 'Red-Curled' cultivar, which followed by 'Man-Choo' and 'Mat-Jjang'. Based on transcriptome analysis, eight genes were involved in glucosinolate biosynthesis. The overall results suggest that the glucosinolate content and accumulation patterns differ according to the kale cultivar and differential expression of glucosinolate biosynthetic genes.

  • This study carried out on the manufacturing of pidan. The production of pidan can be one of solutions for over-produced eggs and stable egg price. For the alkali-pickling solution for manufacturing of Pidan, the tested concentration of NaOH and NaCl were respectively as 3, 5, 7% and 5, 10, 15, 20%, and examined every 2 days for 14days. According to the results, pH value of alkali-pickling solution was increased by the increment of NaOH concentration and the pickling period, and was decreased by the increment of NaCl concentration. The pH value of egg yolk was increased by the increment of NaOH concentration, but it was not significantly different by the NaCl concentration. By the increment of NaOH and NaCl concentrations, the alkali infiltration in egg yolk and egg white was accelerated. Furthermore, the weight change of the eggs in the alkali-solution has no effects on manufacturing of Pidan. Liquefied albumen showed significant differences by NaOH concentration rather than that of NaCl. There was no liquefied albumen for 14days at 3% of NaOH, but it was found between 11-12days at 5% and 8-10days at 7%, respectively. The pH values of egg white when it was liquefied albumen were between 11.8 and 12.0. Pidan was made by heat treatment after 6-7days dipped in the solution at the concentration of 7%, about 10days at 5%, and 12-14days at 3% of NaOH, respectively. Although, the period of manufacturing of Pidan was saved by the increment of NaOH concentration, liquefied albumen was accelerated and the food preference was decreased by ammonia odor. Therefore, the suitable concentration of NaOH is between 3 and 5%, and that of NaCl is between 5 and 10% due to the effect of salinity by the soaking period. Through this study, optimal pickling solution and dipping time for manufacturing of Pidan was figured out, and also find out that it can save a time about 15days for manufacturing of Pidan.

  • The international standard for the school library suggests that school librarians qualified for librarian and teacher should run the school library. And library assistants should support the teacher librarian to carry out a role as a teacher. Despite the difference of requirements, librarians without teachers' license are under the human resources for school library administration. Furthermore, the job description between the school librarian and librarian is not well-defined in Korea. The different requirements in the library standards and the school library related laws have led to weaken professionalism and social status of librarianship. The condition that teacher librarians are not in the school library have brought the pressure to overcome imperfect functions of the school library and unfairness of educational services. In order to solve these problems, it is necessary to strengthen teacher librarians' qualification system to improve their identity as educational subject specialist librarians. We ought to also build proper foundations of social recognition about librarianship through classifying the types of human resources in the school library into the teacher librarian, library paraprofessional and volunteers. Especially we should hold the job analysis based on administrator, teacher, service, leader, collaboration, and partner.

  • The purpose of this study is to design textbook metadata as a basic task for building a textbook database. To this end, reading textbooks were defined as a category of textbooks, and a metadata development methodology was established through previous research. In order to ensure that bibliographically essential elements are not omitted, the catalog description elements of institutions that collect, accumulate, and service textbooks such as the National Library of Korea were investigated. The elements of Dublin Core, MODS, and KEM were mapped to derive elements suitable for describing textbooks. Finally, a set of textbook metadata elements consisting of 14 elements in three categories - bibliography, context, and textbook characteristics were presented by adding publication type, genre, and curriculum period elements. The 14 elements are titles, authors, publications, formats, identification sign, languages, locations, subject names, annotation, genres, table of contents, subjects, curriculum period, and curriculum information. In this study, we contributed to this field by discussing how to organize textbook resources with national knowledge resources, and in future studies, we proposed to evaluate usability by applying metadata elements to actual textbooks and revise and supplement them according to the evaluation results.

  • Cymbidium (C.) spp. 'Wedding Day' was developed by the National Institute of Horticultural and Herbal Science, Rural Development Administration in 2021. This cultivar was derived from the artificial cross between C. 'Boksam Holiday' and C. 'Persicolor' in 2008. After the crossing, 112 seedlings were obtained through in vitro germination and transferred to the green house. Based on their vegetative and flowering characteristics, two lines were selected through the first selection. To confirm the stability and uniformity of the two lines, the first and second trials were conducted from 2017 to 2021. As a result, the final line with the code 'C0844-29' was selected as 'Wongyuo F1-78'. After evaluating consumer preference, the line was named as 'Wedding Day'. This hybrid is medium sized cultivar with long vase life of cut flowers and more than 11 white flowers per stalk. It has 63.2 cm of erect stalks which are suitable for cut flower. The leaves are 65.8 cm long and located lower than the flowers, providing appropriate shape for viewing the flowers. It starts flowering from late January. It has sufficient proliferation ability to enable mass proliferation for commercial use (Registration No. 9523).

  • This study aims for developing an instructional design strategy to improve collaborative teaching between teacher librarians and subject teachers in library-assisted instruction. Collaborative teaching is an important management activity enhancing teaching role of teacher librarians in their school community. But in the actual condition the level of the library-assisted instruction as its practical strategy is cooperation and subject teachers are leading teaching and learning except for selecting resources. Because library-assisted instruction is resource-based learning, the procedural knowledge of information literacy curricula and topics of subject specific curricula should be designed as a whole. Also, there must be possibilities of reducing trial and error and expanding successes. From these sides, the collaborative design strategy for library-assisted instruction can be planned like 'statement of learning situation-co designing-co teaching-co evaluating'.

  • Chestnut processing plants have wasted large amounts of chestnut inner skin waste, which contains chestnut flesh. To review the availability of the chestnut flesh as a food ingredient, We have analyzed the physiochemical characteristics of the chestnut powder extracted from inner skin waste. Then, we have examined on tastes and other sensory tests using breads, noodles and jellies made from various percents of chestnut powder. The results are as follows; The water absorbing capability and amylose degradability of the powder from the inner skin waste are 40% and 8% higher than those of the core chestnut powder, respectively. Also, the power from the inner skin waste shows similar characteristics with one of the core chestnut in iodine reaction. The breads, noodles and jellies from the chestnut powder have similar characteristics in flavor, hardness, elasticity, cohesiveness, adhesiveness, chewing property, and gumminess with the traditional ones.

  • In an attempt to develop natural seasoning materials by use of shellfishes and crustaceans, contents of taste components such as amino acids, nucleotide and its derivatives, the extractability of oyster (Crassostrea gigas), sea mussel(Mytilus coruscus) and crab(Portanus tribuerculata) were investigated. As a result of chemical analysis and sensory evaluation, the optimum condition of extraction could be concluded as extracting fresh or frozen raw materials for about 40 min. at $95^{\circ}C$ with 1.5 to 2 times of water by volume. The contents of free amino acids in the extractions were much in sequence as crab(1,886 mg%), mussel(765 mg%) and oyster(554 mg%), and the dominant amino acids in each extracts were identified as glutamic acid, alanine, glycine, proline and arginine in oyster, threonine, alanine, arginine, glycine and glutamic acid in mussel, arginine, proline, lysine, alanine and threonine in crab respectively. In addition, the major nucleotides affecting as taste enhancer of each extracts were estimated as inosine in oyster and crab, and inosine monophosphate in mussel respectively.
