School is an excellent place for children to loam environment-conscious behavior and for teachers to bring up environmental education. School has a plenty of teaching materials such as school building, pond, school forest, waste and school supplies. Especially, the environmental education for and with school supplies can be very effective, as it is mostly the first products for children to learn the buying and consumption in their daily life. In this study we conducted a survey on the environmental attitude of two groups of 5th graders towards environmentally friendly school supplies. The experimental group received environmental education on school supplies and the control group did not. The survey results showed that almost 50% of the children did not consider the environmental impact, but rather the price, design and function when buying the school supplies. However, more than 70% of children were willing to use the recycled school products, implying that they are aware of environmental Issues and want to contribute to the preservation and improvement of the environment. The children recognized paper/notebooks and paints/crayons as the major environmental problems. Writing appliances such as pens, pencils, highlighters and markers were also considered as environmental concerns, since most of them are made of plastics and they are not easily biodegradable nor refillable. We also exemplify a lesson-plan for environmental education program on school supplies and make suggestions to encourage the use of those eco-friendly school materials.

One of the most important environmental problems is global warming. Global warming is caused by increase in the amounts of water vapor, methane, carbon dioxide and other gases being released into the atmosphere as a result of the burning of fossil fuels. It has thus become important to reduce fossil fuel use. Environmentally friendly preparation of functional materials has, therefore, attracted much interest for environmental problems. Furthermore, nature mimetic processes are recently been of great interest as environmentally friendly one. There have been many studies on fabrication of various functional nanocrystals. Among various nanocrystal fabrication techniques, flux growth is an environmentally friendly, very convenient process and can produce functional nanocrystals at temperatures below the melting points of the solutes. Furthermore, this technique is suitable for the synthesis of crystals having an enhedral habit. In flux growth, the constituents of the materials to be crystallized are dissolved in a suitable flux (solvent) and crystal growth occurs as the solution becomes critically supersaturated. The supersaturation is attained by cooling the solution, by evaporation of the solvent or by a transport process in which the solute is made to flow from a hotter to a cooler region. Many kinds of oxide nanocrystals have been grown in our laboratory. For example, zero- (e.g., particle), one- (e.g., whisker and tube) and two-dimensional (e.g., sheet) nanocrystals were successfully grown by flux method. Our flux-growth technique has some industrial and ecological merits because the nanocrystal fabrication temperatures are far below their melting points and because the used reagents are less harmless to human being and the environment.

The purpose of this study is to examine residents' perceptions of the outdoor spaces of environmentally-friendly apartment complexes focused on quality of life. On-site intercept surveys were performed to collect data and samples were selected from the residents who are currently living in two different environmentally-friendly certified apartment complexes. This study has examined importance and satisfaction of outdoor spaces of the study sites as they relate to quality of life, as well as they correlation between the New Environmental Paradigm(NEP), and satisfaction and loyalty, respectively. Data were analyzed using several statistical methods including descriptive statistics, Importance-Satisfaction Analysis(ISA), t-test, and correlation. The results suggest that outdoor spaces of the apartment complexes are perceived as an important place to improve residents' quality of life. Residents showed a high satisfaction rate to the natural environmental features(e.g. natural areas present, amenity of space) while they showed a lower satisfaction rate to the social environmental features(e.g. access to public transportation). Although most residents tend to have the New Environmental Paradigm based on the study results, NEP did not influence the level of satisfaction in environmentally-friendly apartment complexes. In contrast, there was a significant relationship between NEP and loyalty. In addition, a strong correlation emerged between satisfaction of outdoor spaces and loyalty to the housing estates. Given these results, various recommendations were given to promote better use of outdoor spaces of dwellings to improve residents' quality of life.

The principal objective of this study was to evaluate the consumption behavior of housewives in the Jeonju area with respect to their use of environmentally-friendly agricultural products(EAPs) and to assess the need for EAPs in childcare centers also in the Jeonju area. Self-administered questionnaires were given to and collected from 278 housewives 42.4% of whom employed and 57.6% were unemployed. Statistical data analysis was performed on the data collected using SPSS v. 12.0. The average score of awareness about EAPs was $3.57{\pm}0.56$. The percentage of subjects who purchased EAPS was 76.3% regularly. On this group, 40.3% purchased EAPs 1~2 times in week. Unemployed housewives purchased more than employed housewives by a statistically significant margin(p<0.05). The most-purchased EAPs were vegetables. The average satisfaction score that housewives reported in relation to foodservice provided in childcare centers was $3.66{\pm}0.58$. About 65% of the respondents felt that the EAPs-foodservice in childcare centers was an important factor for them in choosing of a childcare centers. Approximately 42% of the housewives responded that EAPs-foodservice in childcare centers was needed to improve the safety of foodservice provided in chidcare centers. The percentage of subjects who wanted to expand EAPs-foodservice in childcare centers even though the parents would have to bear some of the financial burden was 42.5%. A higher proportion of employed housewives wanted to expand EAPs-foodservice in childcare centers more than unemployed housewives, and this finding was statistically significant(p<0.05).

BACKGROUND: The conazoles, difenoconazole, diniconazole, hexaconazole, penconazole and tetraconazole are a large class of synthetic fungicides used extensively for foliage and seed treatments in agricultural crops. The extensive use of conazoles has brought concerns on the potentiality of environmental contamination and toxicity. Thus studies on the development of methods for monitoring the conazoles are required. METHODS AND RESULTS: A modified quick, easy, effective, rugged and safe (QuEChERS) method was involved in sample preparation. Quadrapole time of flight mass spectrometer (Q-TOF MS) in electron spray ionization (ESI) mode was employed to determine conazoles in garlic samples. The limit of detection (LOD) and limit of quantification (LOQ) of conazoles by Q-TOF-MS ranged from 0.001 to 0.002 mg/L and 0.002 to 0.005 mg/L, respectively. Q-TOF-MS analysis exhibited less than 2.6 ppm error of accurate mass measurements for the detection of conazoles spiked at 0.05 mg/L in garlic matrix. Recovery values of conazoles fortified in garlic samples at 0.02, 0.05 and 0.1 mg/L were between 79.2 and 106.2% with a maximum 11.8% of standard deviation. No detectable conazoles were found in the domestic market samples by using the Q-TOF-MS method. CONCLUSION(s): High degree of confirmation for conazoles by accurate mass measurements demonstrated that Q-TOF-MS analysis combined with a QuEChERS method may be applicable to simultaneous determination of conazoles in garlic samples.

As environmentally friendly life styles become more popular these days, the landscape elements like plants, water, stone etc. which used be considered as just simple interior props, now become the main design concept that decides the whole image of space. The purpose of this thesis is to study the various understandings and approaches on the applications of the landscape elements which are known as the most friendly and positive ways to approach the senses of users, among any other methods and techniques for environmentally friendly elements. The application types of landscape elements in interior space design are as follows; (1) incorporate the surrounding landscape elements. Keeping existing landscape elements, incorporate them into interior elements of beauty; (2) install a transition space with landscape elements; (3) green interior planes ;(4) use landscape as the main design concept; (5) use landscape as decoration elements. Many of landscape spaces incorporated into the interior are often built in a hurry and in low qualities without much consideration of the users and the space. This study intends to set a standard for the application of landscape elements in space design, after collecting various cases that applied the landscape elements in interior space, by categorizing the successful and effective applications into applicable patterns.

This study analyzed satisfaction with and washing of newborn clothing (especially the innerwear washing behaviors) which are considered to be the most basic items among newborn clothing.The survey was conducted on mothers with children under 24 months old. Using an average of 6.7 innerwear items that were changed average 2.3 times a day with baby formula and breast milk representing the main contaminants. When washing clothes for a newborn, respondents were mainly concerned with: rinsing residual detergent, removing stains and contaminants, and sterilization and disinfection. Items were washed by a laundry label to prevent clothes damage. A baby-friendly or environmentally-friendly detergent was used to wash before being worn after purchase was separated and washed in various washing courses of the washing machine every day, boiled, rinsed an average 3.6 times, and dried mainly in the sun. Environmentally friendly cotton (59.5%) and organic cotton (41.6%) products were mainly used; however, items were washed separately from regular laundry. Respondents were satisfied with methods of washing. Consumers are concerned about washing because they think that washing affects a newborn's health. Therefore, it is necessary to provide consumers with appropriate information on washing and establish regulations for the use of harmful substances in newborn clothing and detergents.

This study explored how the elementary schools provided proper interior environments to the students in terms of ecological aspects. 14 cases-7 in Busan and 7 in Osaka which were newly built or remodelled since 2000 were selected. These schools were analyzed based on the eco-school guideline suggested In the former study. The guideline categorizes into three parts: 1) energy efficiency related with lighting, ventilation, heating and insulation, 2) greening, 3) sustainability including recycling water system and use of environmentally friendly materials. The results showed that Korean schools require more systematic planning for natural lighting, ventilation, Insulation, greening and new water system while Japanese schools need use of environmentally friendly materials and consideration for natural lighting, insulation and interior greening. Especially, natural lighting and natural ventilation through roof window, atrium, wind tower and use of natural insulation and blind window system should be basically considered at the Initial planning. Also, this study reveals that ecological approach including greening and natural lighting with various architectural form should be applied in future elementary school design to make the school environment more agreeable and economical.

This Study aims to demonstrate how much flood vulnerability in urban area changed for the past 32 years by using the panel model. At the same time, this study strives to determine the primary factors and to construct an effective counter-plan by means of empirical research. After selecting research hypotheses based on considerations of issues concerning causes for urban flooding, their relevance is put to the test by conducting empirical research in individual case locations. This research verifies the four research hypotheses by using one-way error component regression model. In conclusion, this research has shown that urban land use and local characteristics act as significant flood determinants, with forests acting to reduce flood dangers. Moreover, constructing embankments can no longer represent a reliable flood control policy. The changes in future flood control policies need to incorporate local characteristics and to minimize natural destruction, so that humans and nature can coexist through environmentally friendly flood management policies.
