This study investigated the environmental awareness synthetically with the drawing activity for making up for the weak points in the writing test that cannot measure emotional aspects. This study found that students have negative viewpoints on reasonable judgement for the present and future environment of the earth, while they show hope to live in better environment in their mind. Furthermore, it found that the drawing activity can be adopted as a complement for the traditional measuring method of the environmental awareness, through which this middle school students' sensibility to the environment can be shown. It also inferred that the drawing activity can be used as a way of education during school classes for environment and it can increase the sensibility to the environment in mind.

This article extracted feasible elements for an environmental education program from the 'Intelligent Life', an integrated subject of the 7th elementary school curriculum, and designed a program for second graders in the elementary school and applied it to them in order to examine how the students' environmental altitudes changed. In the controlled class, the instruction followed the lessons specified in the 7th national curriculum faithfully while for the experimental class 1, only the inquiry activity-based environmental education program was applied. Moreover, in experimental class 2, the inquiry activity-based environmental education program was implemented and wrap-up activity was performed as well with the products. To verify the program, questionnaires on the change of environmental altitudes were distributed and analyzed total three times in the pretest, posttest 1(right after the program), and posttest 2(30 days after the program). T-test was carried out with the SPSS 12 program to verify the effect of the applied program. To make up for the quantitative analysis, qualitative analysis was also conducted. The followings show the results gained after the program was implemented. First, This program showed a significant difference(p<.05) in the students' formation of environmental altitudes. Second, it was verified that the inquiry activity-based environmental education class that reorganized the second grade elementary students' 'Intelligent Life' subject had a more positive effect in the cultivation of environmental altitude than the class that followed the present curriculum as it was. It will be necessary to perform follow-up researches on the relativity between curricula for kindergarteners and lower grade elementary school students.

The purpose of this study is to find out the tendency of the new generation’s consumer roles and green consumption behavior for the environmental conservation. This study is also to reveal some fundamental information for an environmental education program which si able to support the new generation consumers to participate voluntarily in an environmental activity. The 500 subjects of this study were selected from the new generation consumers who wre residing in Seoul, 1998. The 414 data wre finally analyzed by Mean, t-Test, ANOVA, and Multiple Regression Analysis. The major findings were as follows: 1) the purchasing roles of the new generation consumer tended to be higher than the citizen participation’s roles. The variables with the higher score for the new generation’s green consumption behavior were in the rank of the isolation of environmental waste, the purchasing behavior of green product, the recycling environmental resource, and citizen’s participating roles in environmental activity. 2) the new generation’s consumer roles showed a significant differences, according to variables for the environmental value, environmental education, and participation of the environmental and societal activity 3) the green consumption behavior for the new generation consumers showed a significant differences, according to sex, environmental value, participation of the environmental and societal activity. 4) the most influential variables for the green consumption behavior of the new generation consumers were in the rank of consumer roles, educational values, and the participation of the environmental activity. As we see above, the consumer education for the new generations needs to focus on consumer’s roles that let them participate voluntarily in environmental and societal activity, as well as practice positively to use green environmental products whenever they select some items in the markets.

This study was aimed at evaluating the antioxidant activities of methanol extract of Thamnolia vermicularis. The antioxidant activity, reducing power, superoxide anion radical scavenging and free radical scavenging activities were studied. The antioxidant activity of the extract correlated with its concentration ($0.2{\sim}2\;mg/ml$) in the reaction mixtures containing linoleic acid. Upto 67% of lipid peroxidation was inhibited by 2 mg/ml of the lichen extract. The extract showed strong free radical scavenging activity similar to that of BRA (positive control) in a manlier of concentration dependent. The lichen extract also showed moderate effects on superoxide anoin scavenging activity and reducing power, which was not so effective as that of Quercetin and BHA used as positive controls. This study suggests that T. vermicularis lichen can be used as a novel source of natural antioxidant.

Personal exposure relies on characteristics of time activity patterns of the population of concern as human activities impact the timing, location, and level of personal exposure. The information about time spent in microenvironments plays a critical role for personal exposure to air pollutants. It is useful to determine the precise times of the day that the subjects are in certain locations or engaging in specific activities because exposure to some air pollutants can depend on temporal trends. This study investigated time activity pattern for workers of Korean population over 19 years old with 8,778 workers in weekday. The residential indoor times were 12 hours. Time activity was different by gender and the mean times stayed at home in weekday were 12.9 hours in female and 11.42 hours in male, respectively. The major factors on residential indoor time and workplace time were age, monthly income, occupation and industry type, work position, education, and gender. Considering shorter than those in other countries, Korean workers spent less time at home after the working hours. Determinants of time activity pattern need to be taken into account in exposure assessment, epidemiological analyses, exposure simulations, as well as in the development of preventive strategies. Since there are substantial difference of Korean worker activity pattern, this information can be critical for exposure assessment in Korea.

In this study, degradation of estrone (E1) and $17{\alpha}$-ethynylestradiol (EE2) by gamma-irradiation and subsequent reduction of estrogenic activity as a function of absorbed dose were conducted using the yeast two-hybrid assay. Relative potency of E1 and EE2 compared to estrogenic activity of $17{\beta}$-estradiol (E2) was found to be 0.0144 and 0.1605, respectively. More than 90% of E1 and EE2 (both $5.0{\times}10^{-6}M$) was removed at an absorbed dose of 5 kGy, but more than 40% of estrogenic activity still remained. The addition of $TiO_2$ catalyst appeared to improve the removal efficiency of E1 and decrease estrogenic activity while there was no significant effect for EE2. Additionally, the calculated estrogenic activity of E1 and EE2 based on a regression model was well correlated with the observed activity.

Lactic Acid Bacteria (LAB) are among the representative probiotics that have been used for a long time in fermented food. Although there are many studies on detecting the radical scavenging activity of LAB, few studies have been conducted on the environmental factors that improve scavenging activity. This study investigated the environmental factors affecting the DPPH radical scavenging and various antioxidant activities of Kimchi-derived Lactobacillus plantarum K-21 with antihypertensive and radical scavenging activities. The optimal conditions for scavenging DPPH radicals were glucose 2%, bactopeptone 0.5%, Tween 80 0.05%, L-cysteine 0.05%, and an initial pH 6.5 at 35℃. Under optimal conditions, the DPPH radical scavenging activity was 94.8±2.2%, which was 1.5 times higher than that of the basic medium. In addition, L. plantarum K-21 had other antioxidant activities; ABTS radical scavenging (93.6±1.5%), hydroxyl radical scavenging (8.5±0.9%), metal chelating (65.9±0.5%), NO scavenging (53.1±19%), SOD-like (25.1±1.5%), and reducing power (11.7±1.4%) activities were detected. Therefore, L. plantarum K-21 may act not only as a starter for lactic acid-fermented foods with improved functionality but also as a drug for various diseases caused by oxidative stress.

Purpose: This study was conducted to examine the personal and social environmental factors affecting leisure time physical activity (LTPA) among adults living in rural communities. Methods: A cross-sectional study was conducted with a convenience sample of 282 adults living in three rural towns of Chungcheongbuk province. Leisure time physical activity was assessed through the Korean version of the Global Physical Activity Questionnaire (GPAQ), and social influence and social cohesion of social environment were assessed using reliable and validated measures. Multiple logistic regression analysis was conducted to explore personal and social environmental factors associated with LTPA. Results: The overall prevalence of leisure-time physical activity (LTPA) was 40.0%. Multiple logistic regression analysis showed that LTPA participation was associated with gender (OR=2.60, 95% CI=1.47-4.58), healthy eating (OR=1.15, 95% CI=1.01-1.31), unhealthy eating (OR=0.70, 95% CI=0.53-0.93) and social influence for physical activity (OR=1.11, 95% CI=1.03-1.20). However, social cohesion was not correlated with engaging in LTPA. Conclusion: Both personal and social environmental factors are associated with LPTA among rural adults living in Eup-Myen regions. Interventions to promote LTPA would likely benefit from considering healthy dietary intake and social influence for physical activity.

The objectives of this study were: a) to measure the satisfaction of who volunteered in the activity, and b) to identify factors related to their satisfaction from the activities, and c) to provide policy implications to improve their satisfaction. This study was based on a literature review and empirical analyses. The empirical analyses have been completed through individual interviews with community residents who volunteer the NGO activities in the Korean Federation for Environmental Movement. The major findings from empirical analysis were as follows: As a result of correlation analysis, nine variables affecting the degree of their satisfaction were "activity time", "sex", "support of family and friends", "understanding of environmental NGO activities and fields of environmental NGO activities", "contact points for the activities", "income and vocation". As a result of multiple regression analysis, the five variables affecting the degree of their satisfaction were "understanding of the NGO activities", "income", "support of family", "marital status", "activity period" and these five variables explained 49.1% of the degree of their satisfaction. Based on the empirical findings, the following suggestions could be offered for the environmental NGO activities. 1) Environmental NGOs should offer resident-friendly programs which may help the residents participate in the NGO activities, so the volunteers can participate in the activities with their family, friends, and neighbors. 2) Environmental NGOs should provide appropriate information and educational supports to community residents, which might facilitate them to have a sound understanding of the NGO activities. And the environmental NGOs should provide diverse activity programs to facilitate participation and to formulate eligible management system for the activities. 3) To enhance the satisfaction of participation, environmental action programs should be organized and conducted through a careful consideration of the status of the community, the characteristics of residents, and so on. To provide better contact points, environmental NGOs should cooperate with religious organizations in communities, social groups, media and so on.
