21st century has begun as an age of green growth. Development paradigms disregarding environmental sustainability are being changed and henceforth, stronger efforts should be made to discover and utilize green values. With the importance of green values, rural amenity which is in the spotlight as a new channel to change the way people think about depressed agriculture and rural community could be the key to discover green values of rural area. This study is to emphasize rural amenity and to rectify prejudiced and distorted contents of agriculture and rural community in agricultural highschool textbooks. By doing this, students of agricultural highschool who will lead agriculture in the future will come to recognize the importance of agriculture and rural area and discovering it's values. This study was done through analysis and development of contents in 39 kinds of textbooks of Agricultural highschool. A content analysis was employed to examine to what extent the contents on agriculture and rural community were reflected in the textbooks of agriculture highschool. And 262 new education contents formulating positive and exact rural amenity concept were developed and 62 of them were included in textbooks.

This study was conducted to collect basic data for establishing a revitalization plan for agricultural machinery departments in technical high schools. A status survey on satisfaction and career plan of students majoring in agricultural machinery in technical highschool was measured. The survey results showed that the selection motivation for technical high school was mainly due to the academic score obtained during middle school, and an academic major for agricultural machinery was mainly based on personal interest and aptitude. About 90% of the students answered as "normal" or "satisfied" to the questions asking satisfaction level for agricultural machinery major and education. For career plan, 68.5% of the students answered as "entrance into academic schools for higher level education" and 31.5% answered as "employment". Most preferred higher level education area was "engineering" (30.8%) and "agricultural machinery" was only 12.6%. Expecting employment area was also automobile or other industrial machinery rather than agricultural machinery.

As an effort to realize the results of last two years of study, this study had three distinguished purposes: 1) confirming whether some requests for corrections had been accepted or not 2) making a list of possible errors found in newly written textbooks and asking to fix them, and 3) classifying forest related contents identified in the textbooks according to the 150 topics included in information material, so called Forest IQ 200. Among 94 errors associated trees, forest or forest education, only thirteen of them were found to be fixed according to the request made in previous study of 2008. Especially, most of the fixed errors were identified to be in natural and social science subject textbooks and nothing was found in art and language areas. Total of 1,320 forest related items were found in the textbooks at the level of kindergarten to 10th grade(freshman in highschool). Korean student was expect to have a chance to learn forest related items 1.64 times a week for 10 years(First to 10th grade). Analyzing 1,109 contents in terms of four topic areas of forest education, the forest culture area was found to have most content of 348 including painting and recreation. Some suggestions were made to make school forest education better, and publishing the forest textbook for elementary schools was one of them.

This study was motivated to understand ways in which actors (students) perceived internal and external conditions of actions in determining responsibility of so-called environment friendly actions. To understand hidden reasons by which students conduct specific environmental actions more or less frequently may be more important and meaningful for environment teachers than to measure and know the frequency that their students do such actions. This study has been implemented by applying questionnaire survey to 752 ruddle school and high school students and 211 environment teachers. To test the hypothesis of this study that there would be significant differences in awareness of environment friendly actions and barriers to implementing those actions between students and environment teachers, frequency analysis and f-test have been conducted. Primary results of this study can be summarized as follows; It has been found that there were a number of evidences showing significant differences in awareness of environment friendly behavior between students and teachers. In term of action frequency, significant differences have been observed in 11 of the listed 20 actions. Similar resulted have been found in terms of perceived difficult, perceived effectiveness, and perceived guilty. These results seem to support an argument that the current list-making and checklist style of connecting students to so-called environment friendly actions need to be reviewed in a critical manner.

Nonwovens have been widely used in various regions from the households to the industrial, agricultural and medical goods. Synthetic fibers have been used for source of nonwovens commonly because of their useful and economic properties. They are not only main factor causing environmental problems but also spend huge cost to renew the environmental disruption by them. Nonwovens must have both cost-competitiveness and environment-friendly property to be the desirable sources in 21th centuries. For meet these needs, it is suitable for the times that economical and environmentally-safe kenaf fibers would be used as raw materials of nonwovens. Kenaf and polyester fibers were blended in 4 types of ratio : 0/100, 20/80, 40/60, 60/40 were needle-punched. The nonwovens properties such as color values, surface appearance, strength, elongations, stiffness, moisture regain, water and oil absorbency, and electrification were tested. As the results, tensile and tear strengths, water and oil absorbency were maximum at 20/80 kenaf/polyester blend nonwoven, because of effecting by nonwoven structure and fiber properties. The moisture regain were increased according to kenaf were blended and the eletrification reduced in proportion to the kenaf fibers by chemical property of fiber composed nonwovens.

Almost 10~30% of vegetables were discarded by the spoilage from farms to tables. After harvest, vegetables are often spoiled by a wide variety of microorganisms including many bacterial and fungal species. This investigation was conducted to extent the knowledge of relationship the spoilage of vegetables and the diversity of microbes. The total aerobic bacterial numbers in fresh lettuce, perilla leaf, and chicory were $2.6{\sim}2.7{\times}10^6$, $4.6{\times}10^5$, $1.2{\times}10^6\;CFU/g$ of fresh weight, respectively. The most common bacterial species were Pseudomonas spp., Alysiella spp., and Burkholderia spp., and other 18 more genera were involved in. After one week of incubation of those vegetables at $28^{\circ}C$, the microbial diversity had been changed. The total aerobic bacterial numbers increased to $1.1{\sim}4.6{\times}10^8$, $4.9{\times}10^7$, and $7.6{\times}10^8\;CFU/g$ of fresh weight for lettuce, perilla leaf, and chicory that is about $10^2$ times increased bacterial numbers than that before spoilage. However, the diversity of microbes isolated had been simplified and fewer bacterial species had been isolated. The most bacterial population (~48%) was taken up by Pseudomonas spp., and followed by Arthrobacter spp. and Bacillus spp. The spoilage activity of individual bacterial isolates had been tested using axenic lettuce plants. Among tested isolates, Pseudomonas fluorescence and Pantoea agglomerans caused severe spoilage on lettuce.
