The purpose of this research is to analyze content elements of Housing area in 2013 middle school Technology Home Economics textbooks 1 and 2, total of 22 according to 2009 revised curriculum. The analysis method was content analysis, focusing on contents of main text, tables & figures, reading material, and activity materials by their content elements. This research will contribute in obtaining suggestion for the post curriculum/textbook development and helping teachers to perform a lesson. The results are as follows. First, Housing area included 1 to 4 content elements per each units, from 2 chapters and 6 units. The content elements stated in Home economics curriculum were total of 16 which consists of 'the meaning of housing,' 'housing types,' 'family forms,' 'family life style cycle,' 'life style,' 'neighboring environment,' 'co-living values,' 'air environment,' 'heat environment,' 'light environment,' 'acoustic environment,' 'space division,' 'circulation', 'effective use of space,' and 'sustainable dwelling practice.' All of these components are dealt with in every textbooks. Second, the numbers of content elements provided in each textbooks were the same, however they showed difference in their contextual aspect. Some contents need supplemental material for their lacking content element. Others need proper understanding of the concept because some showed different contents from the appropriate content elements. Third, repetitions in content elements were observed, the contents of 'co-living values' in textbook 1 and 'sustainable dwelling practice' in textbook 2 were similar in terms of eco-friendly housing, co-housing and universal housing. These two content elements should be merged as one next curriculum, or should be stated together in one subunit.

The free learning semester system focuses on the activation of career education of middle school students as an educational policy that links career recognition in elementary school, career search in middle school, and career planning in high school. This system was fully implemented in 2016 and public libraries also provided various programs. This study analyzed the free learning semester system programs of public libraries in Busan city and demonstrated the contribution of local development. As a result, career and job search, career exploration and experience, and information literacy enhancement programs contributed to local knowledge culture, reading culture, learning culture, living culture and leisure culture. However, contribution of reading exhibitions, job experience, information literacy enhancement to the leisure culture and local economy were limited. Therefore, it is desirable that all libraries should add programs related to knowledge ecosystem structure, digital information gap, human healing, social environment issues, future job prospects, and provide information literacy programs.

The goal of this study is to compare the evaluation results of indoor daylight environment for each certification and propose improvement points. As the importance of indoor daylight environment has increased, foreign countries have been aware of this and have changed the light environmental certification items. On the other hand, Korea environmental certification systems have not been able to follow the current situation. In order to improve this, this study intended to find evaluation criteria for each category by comparing and analyzing indoor daylight environment certification items in Korea's G-SEED, LEED in the United States, BREEAM in the UK, and CASBEE in Japan. After that, this study simulated 3D models of three spaces about classroom, reading room and club room of Yanghyun elementary School which is scheduled to be constructed for the evaluation of indoor daylight environment, and the results were analyzed to suggest for improvement.
The international environmental activity and environmental education began in 1970's. Environmental education in Korea was emphasized since the Forth National Curriculum. The Environmental Curriculum was regarded as one of the most important part in the Sixth National Curriculum in Korea. Environment-related reference texts of Elementary school were already developed. Soon, 'Environment' of middle school and 'Environmental Science' of high school will be developed. The purpose of this study were to analyse environment-related texts in the Fifth National Curriculum and to measure how much environmental education has achieved. As a environmental text for regular class, selected the environmental part in 'Science Part 1' and as environment-related reference text, 'Survival and Environment'. The environmental part of 'Science Part 1' was unit [Life and Environment]. According to the analysis of objectives, most of unit objectives were not stated in a detailed and precise manner. When the goals of environmental education were divided into four fields as follows, knowledge and information, skill, thinking and attitude, behavior and participation, unit objectives were mostly emphasized on knowledge and information of environment, exactly 44.5% of unit objectives and 89.6% of subunit objectives. The degree of relationship between unit objectives and contents was low. All the Check up-problems were about knowledge and information of environment. Environment-related reference text, 'Survival and Environment' was the only reference text for high school students in Korea and was organized in the form of the regular curriculum text. It was developed in Korean Education Development, Center with support of Korean Environmental Ministry in 1990. According to the analysis of 'Survival and Environment', the objectives of units and subunits were less stressed on knowledge and information than those of unit [Life and Environment] in the environmental part of 'Science Part 1' On the other hand, they were a little more stressed on skill, thinking and attitude, behavior and participation. And fifteen of all the seventy subunit objectives were not related with contents. In organization, this text included Thinking problems, Experiments and Inquiries, Reading, Developed studies and Check up-problem etc. It was remarkable that Inquiries leaded to individual activities and Developed studies to group discussions or individual inquiries. And as Check-up problems were presented as a form of activities, students could achieve many various objectives at the same time by solving one problem. To measure the achievement of environmental education by questionnaire, 497 high school students in total were selected from five different schools. Scores in subtest 'behavior and participation' and subtest 'thinking and attitudes' were 13.19 and 18.18, respectively. Actually, most students had a positive thinkings and attitudes in their hearts about environmental problems, but many of them actually did not take actions to solve environmental problems and to protect environment. Scores in subtest 'knowledge and information' and subtest 'skill' were 10.76 and 10.81, respectively. The higher the score students got in 'knowledge and information', the higher the score in 'skill'. It implies that learning of skills is based on learning of knowledges and informations about environment has not always ensured positive thinkings and attitudes or active behaviors and participations to solve environmental problem.

The standards for instructional media and equipments imply an essential element for curriculum. In knowledge-based society, school libraries are an educational environment to assist curriculum, offer information literacy and reading services. Therefore the standards for school libraries instructional media and equipments are able to suggest the mission of school library media center, and it should contain suitable elements for educational roles. But the current standards are insufficient from quantitatively as well as qualitatively. So the standards, if standards for instructional media and equipments are revised, should be contain following contents. 1. facilities guidelines: 2. basic equipment plan; 3. instructional media for educational roles; 4. equipments for each essential. area space: 5. more detailed information appliances; 6. improvement of standard for special school library

This study aims to examine the current status of managing elementary school libraries in Busan and suggest the ways to improve it with the viewpoint of 'the five laws of library science'. The scope of study was set as the elementary school libraries in Busan, and the operation status of 304 elementary school libraries was analyzed. And for in-depth investigation, D elementary school library was examined as a case. The operation status of elementary school libraries in Busan was analyzed with the analysis elements; existence of school library, placement of teacher librarian, library collection, annual use, budget, and library seats for 6 years from 2016 to 2021. As a result, especially the placement rate of full-time teacher librarians was only 10.5%, indicating that the problem of manpower shortage was serious. As case study, the current state of managing D elementary school library was deeply investigated with perspectives of the first law and the third law of library science among Ranganathan's five laws of library science. With the first law, the investigation was divided into the aspects of open-shelf system, library location, library hours, furniture, and staff. With the third law, the investigation was done as the aspects of shelf arrangement, catalog, extended service, book selection. Especially, books with more than 50 copies for the program of reading one book each semester accounted for 4.8% of the total collection, showing the problem of unbalanced collection. As the result of this study, 'expanding the placement of teacher librarians', 'making better reading environment through remodeling', and 'balanced collection development' were suggested as the ways of developing school libraries.
Aspergillus fumigatus is one of the most common fungi in the human environment, both in-doors and out-doors. It is the main causative agent of invasive aspergillosis, a life-threatening mycosis among immunocompromised patients. The genome has been sequenced by an international consortium, including the Wellcome Trust Sanger Institute (U.K.) and The Institute for Genomic Research (TIGR, U.S.A.), and a ten times whole genome shotgun sequence assembly has been made publicly available. In this study, we identified tricarboxylic acid (TCA) cycle enzymes of A. fumigatus by comparative analysis with four other fungal species. The open reading frames showed high amino acid sequence similarity with the other fungal citric acid enzymes and well-conserved functional domains. All genes present in Saccharomyces cerevisiae, Schizosaccharomyces pombe, Candida albicans, and Neurospora crassa were also found in A. fumigatus. In addition, we identified four A. fumigatus genes coding for enzymes in the glyoxylate shunt, which may be required for fungal virulence. The architecture of multi-gene encoded enzymes, such as isocitrate dehydrogenase, 2-ketoglutarate, succinyl-CoA synthetase, and succinate dehydrogenase was well conserved in A. fumigatus. Furthermore, our results show that genes of A. fumigatus can be detected reliably using GlimmerM.

Objectives: There are many hazardous agents at livestock farms. In particular, gases can be detrimental to both workers and animals. This study evaluated ammonia and hydrogen sulfide concentrations in broiler hen barns and beef cattle barns according to sampling location and height. Methods: Three broiler hen barns and three beef cattle barns were selected for gas monitoring in this study. Ammonia and hydrogen sulfide concentrations were measured using a direct-reading instrument which could measure the target gases simultaneously. Gas monitoring was conducted at human breathing height and animal breathing height at three points in each livestock farm. Results: Ammonia concentrations at the broiler hen barns ranged from 3.3 to 12.5 ppm by sampling location and height, but hydrogen sulfide was not detected. In the beef cattle barns, ammonia ranged from 3.1 to 16.3 ppm and low concentrations of hydrogen sulfide were detected at some animal breathing heights. The gas concentrations detected at each livestock farm were significantly higher in the animal breathing zones than in human breathing zones (p<0.0001). Conclusions: We found a difference in gas concentrations between human breathing zones and animal breathing zones. Gas monitoring should be conducted to improve the related environment considering both workers' and animals' health and safety.
Ambient particulate matter (PM) and particle-bound polycyclic aromatic hydrocarbon (PAH) concentrations were measured continuously for 70 days at a Korean elementary school located near a highway. The $PM_{10}$, $PM_{2.5}$, and $PM_1$ values were measured with a light-scattering, multi-channel, aerosol spectrometer (Grimm, Model 1.107). The number concentrations of the particles were measured using a scanning mobility particle sizer and counter (SMPS+C) which counted particles from 11.1 to 1083.3 nm classified in 44 channels. Particle-bound PAHs were measured with a direct reading, photoelectric aerosol sensor. The daily $NO_2$, $SO_2$, and CO concentrations were obtained from a national air-monitoring station located near the school. The average concentrations of $PM_{10}$, $PM_{2.5}$, and $PM_1$ were 75.3, 59.3, and $52.1{\mu}g/m^3$, respectively. The average number concentration of the ultrafine particles (UFPs) was $46,307/cm^3$, and the averaged particle-bound PAHs concentration was $17.9ng/cm^3$ during the study period. The ambient UFP variation was strongly associated with traffic intensity, particularly peak concentrations during the traffic rush hours. Particles <100 nm corresponded to traffic-related pollutants, including PAHs. Additional longterm monitoring of ambient UFPs and high-resolution traffic measurements should be carried out in future studies. In addition, transient variations in the ambient particle concentration should be taken into consideration in epidemiology studies in order to examine the short-term health effects of urban UFPs.

Pseudomonas fluorescens MC07 is a growth-promoting rhizobacterium that suppresses mycelial growth in fungi such as Rhizoctonia solani, Pythium ultimum, Fusarium oxysporum, and Phytophthora capsici. To determine the role of the bacterium's antifungal activity in disease suppression, we screened 2,500 colonies generated by Tn5lacZ insertions, and isolated a mutant 157 that had lost antifungal activity. The EcoRI fragment carrying Tn5lacZ was cloned into pBluescript II SK(+) and used as a probe to isolate wild-type clones from a genomic library of the parent strain, MC07. Two overlapping cosmid clones, pEH4 and pEH5, that had hybridized with the mutant clone were isolated. pEH4 conferred antifungal activity to the heterologous host P.fluorescens strain 1855.344, whereas pEH5 did not. Through transposon mutagenesis of pEH4 and complementation analyses, we delineated the 14.7-kb DNA region that is responsible for the biosynthesis of an antifungal compound. DNA sequence analysis of the region identified 11 possible open reading frames (ORF), ORF1 through ORF11. A BLAST search of each putative protein implied that the proteins may be involved in an antifungal activity similar to polyketides.
