  • We examine the effect of environment on star formation activity of a sample of galaxy group catalogue given in Tempel et al.(2012) constructed from the Sloan Digital Sky Survey Data Release 8. In order to compare galaxies in different environment, we classify galaxies into two groups: galaxies in low density environment and galaxies in high density environment. After matching colors and apparent magnitudes of the galaxies, we are left with 5912 galaxies in each of the environment category. The fraction of star-forming galaxies in low-density environment is ~34%, higher than ~15% in high-density environment. Star-forming galaxies in low density environment have a higher average SFR value than those in high density environment. The bulge-to-disk ratio for galaxies in two different environment shows bimodal distribution. Regardless of the environment, we find galaxies with high star formation rate despite their red (g-r) color, for which the origin enhancing their star formation rate is investigated.

  • The purpose of this study is to tender as the basic data for practice of environment on the consciousness and practice of life environment on technical teacher in middle school and colleage students. For this purpose, the data were collected by using questionnaire distributed to 102 technical teacher in middle school and 103 male colleage students in Jan. and Aug., 2000. The major findings of this research are as follows; 1. It was found that the teachers had consciousness in industrial environment pollution but the students has the causes of house or car. All of the subjects set to the environment information through T.V. programs and the efficacy is highest. Also the teachers set to the environment information through environmental organization and books. The teachers had concern of high level and higher than the students on the life environment. Specially the awareness of life environment was upper to the average and higher than students. 2. The assessments of the earth life environment was 69.17(M), the oceanic environment was highest and water environment was lower. The assessments of the Korea life environment was 60.67(M) were lower than the assessments of the earth life environment, all items were lower than earth lie environment. Generally leachers has positive assessments to earth and Korea life environment than male students. 3. The teachers have high practice apparence on the life environment than the students. Also the teachers had upper to the average on the practice degree, and the practice degree lower than practice awarences. But all items on practices degree was higher than student's.

  • The purpose of this study is to clarify the actual condition of real certification schools of environment-friendly architecture per ecological environment elements through extracting ecological environment elements which is possible to analyze in quantity certification standards of environment friendly architecture. As the method of this study, firstly, certification as an examination on certification system of environment-friendly architecture, summary of certification system of environment-friendly architecture and eco-school pilot model project, ecological environment elements which is possible for quantitative analysis of ecological environment certification standards were extracted. Secondly, actual condition of ecological environment elements per school grade by collecting actual data of certification schools environment-friendly architecture were analyzed. The average of ecological area ratio was 24.5 percent in case of this certification regardless of school grade and region and it was analyzed that the natural based green area ratio was 22.9 percent, bio-tope area ratio was 0.60 percent and ecological learning places area ratio was 0.39 percent.

  • Purpose: The present study purposed to investigate the current state of harmful business places around schools and to survey and analyze how much middle school students know about school environment hygiene purification zones, which have not been much effective. Methods: In addition, this study clarified the problem of harmful environment around schools by inquiring into students' value and perception on worsening harmful environment around schools and provided basic materials necessary for making policies on school education and the protection of educational environment. For these purposes, we conducted a questionnaire survey of 1,000 middle school students in Gyeonggi-do on their perception on harmful environment around their schools, and drew conclusions as follows. Result: Students' knowledge about the School Health Act was low, and they generally thought that the law does not play its role substantially and efficiently in purifying and regulating harmful environment and regulations are superficial and temporary. To the question of whether harmful businesses observe laws for purifying environment around schools, most of the students replied negatively. In actuality, as most of harmful businesses running at school environment hygiene purification zones are stationeries with game rooms, comic book stores, PC rooms, etc., which are highly accessible to students, they become serious problems in school environment. Conclusion: As it is required to make continuous and systematic surveys and researches on the school environment hygiene purification zones, we need to manage school environment efficiently through cooperation among the government, education offices and individual schools.

  • The environment-friendly agricultural product market receives consumers' great interests despite relatively few studies focused on consumers' decision making process of the environment-friendly agricultural products. This paper examines what factors influence on consumers' attitude and buying behavior on the environment-friendly agricultural product. In order to find the relative importance of each factor's influence, this study adopts multiple regression method based on the survey results of 500 people with the systematic random sampling. The results showed that consumers' favorable attitude towards the environment-friendly agricultural product were influenced by taste, freshness, food safety, and positive attitudes toward the environment-friendly agricultural product promotion. In addition, consumers' purchase intention was influenced by taste, food safety, environmental concern, and the promotion. Respondents recommend the environment-friendly agricultural product when they believe that the environment-friendly agricultural product had the values of taste, environmental concern, and promotion. Women are more active in buying and recommending the environment-friendly agricultural product; however, the price was not the statistically meaning factor. This study provides empirical data that was used for marketing and increasing the sales of the environment-friendly agricultural product. Future research was advised to examine more thoroughly on the relationships between the promotion efforts and purchase intention and the occasions when the price becomes the issue in the buying decision of the environment-friendly agricultural product.

  • In this paper, the factors influencing the differentiation of environment-friendly agricultural products from the intention of environment-friendly farming experience were analyzed through logit analysis. The main analysis results are summarized as follows. First, the contents to experience in environment-friendly agricultural innovation in Jeonnam province are environment-friendly agricultural product harvesting (33.8%), making food using environment-friendly agricultural products (24.1%) and environment-friendly ecological experience (20.1%). Second, significant variables affecting the intention to experience environment-friendly agriculture were analyzed as whether they were members of the consumer cooperative, whether they were children under the age of two, and whether they were children under the age of high school. In other words, it was analyzed that the more members of the consumer cooperative, the more families with children under the age of two, and the more families with student children, the more likely they are to participate in environment-friendly farming experiences. Third, significant variables that affect the recognition of the differentiation of environment-friendly agricultural products in Jeonnam province were found to be environment education and dual income. In other words, it is analyzed that consumers who receive environment education and dual-income families are more likely to recognize environment-friendly agricultural products in Jeonnam province differently than in other regions.
