This paper intends to investigate the hierarchical effects of personality variables and values on pro-environmental product purchase and recycling behaviors mediated by 3 factor environmental attitudes. Previous literature review on pro-environmental behaviors has three categories of research trends. The first category generally done during 70's and early 80's is mainly focused on identifying pro-environmental consumer groups. Second stream of studies has focused on the mediating and moderating effects of variables, such as PCE, environmental knowledge, the perceived importance of behavioral consequences etc., on various pro-environmental behaviors. The last and latest trends of literature is focused on hierarchical and interactive effects of variables on behaviors. Following the trends of literature is review of such specific variables as social responsibility, community mindedness, locus of control, values, and environmental attitudes. The result shows that both locus of control and social responsibility have positive effects on two of environmental attitudes, harmony with nature and limits to growth, but community mindedness did not have effects on environmental attitudes. And social belonging value has positive effects on two of environmental attitudes, limits to growth and nature over human, and environmental value has positive effects on the formation of harmony with nature and limits to growth. But self-actualization has negative effects. And it's also suggested the positive effects of environmental attitudes on purchase and recycling behaviors. Specifically, all environmental attitude variables have positive effects on the formation of pro-environmental product purchase and recycling behaviors except in case of the effects of nature over human to recycling. And it's also revealed that pro-environmental product purchase is a preceeding behavior to recycling behavior, which suggest that consumers have to purchase environment friendly and recyclable products in order to engage in effective recycling behavior. Various applications of the results are discussed in the conclusion.

The purpose of this study was to investigate the influence of the energy campaign environmental education of 3rd graders in elementary school in Seoul. The students were divided into an experiment group and a control group. A reconstructed questionnaire through Kim(2005) and Lee(2005)'s test tool was used to survey the effects of applying the energy campaign environmental education program. The i-STATistics program was used to analyze the results. The major results of this study are as follows. First, the researcher was able to develop and apply teaching-learning model for energy campaign environmental education by extracting and recreating the energy education-related contents from the lower grades(1, 2, 3 grade) in 2007 elementary school curriculum. Second, this program had a positive effect on pro-environmental altitudes of elementary school students. Third, this program had a positive correlation among the 3 subdomains of cognitive, affective and behavioral. Fourth, according to qualitative analysis, the students appear to be more concerned in the overall environmental problems containing energy problem and showed a higher will to act while participating in the environmental education through energy campaign program. In conclusion, this program is more directly effective than lectures on energy following the curriculum to improve student's pro-environmental altitudes. Therefore, more intensive research on teaching and learning activities should be highly considered.

Background: A very high incidence of lung cancer is observed in Mizoram and Manipur, North East India. We conducted a population based case control study to establish associations of p53 codon 72 polymorphisms and interactions with environmental factors for this high incidence. Material and Methods: A total of 272 lung cancer cases and 544 controls matched for age (${\pm}5years$), sex and ethnicity were collected and p53 codon 72 polymorphism genotypes were analyzed using a polymerase chain based restriction fragment length polymorphism assay. We used conditional multiple logistic regression analysis to calculate adjusted odds ratios and 95% confidence intervals after adjusting for confounding factors. Results: p53 Pro/Pro genotype was significantly associated with increased risk of lung cancer in the study population (adjusted OR=2.14, CI=1.35-3.38, p=0.001). Interactions of the p53 Pro/Pro genotype with exposure to wood smoke (adjusted OR=3.60, CI=1.85-6.98, p<0.001) and cooking oil fumes (adjusted OR=3.27, CI=1.55-6.87, p=0.002), betel quid chewing (adjusted OR=3.85, CI=1.96-7.55, p<0.001), tobacco smoking (adjusted OR=4.42, CI=2.27-8.63, p<0.001) and alcohol consumption (adjusted OR=3.31, CI=1.10-10.03, p=0.034) were significant regarding the increased risk of lung cancer in the study population. Conclusions: The present study provided preliminary evidence that a p53 codon 72 polymorphism may effect lung cancer risk in the study population, interacting synergistically with environmental factors.

BACKGROUND: The vigorous shoot growth in upper part of apple tree canopy leads to poor fruit quality and flower bud formation in lower part of canopy. So, this study was conducted to develop the proper control method about the shoot growth in upper part of apple tree canopy. METHODS AND RESULTS: Trunks of 'Fuji'/M9 apple trees were cut (back pruned) to 2.5 m in tree height on 11 February (dormant) or 12 April (full bloom). Naphthalene acetic acid (NAA) was applied at 2.0% to cut surface when trunk was pruned. Prohexadione-calcium (Pro-Ca) was sprayed at 250 mg/L above 2.0 m in tree height at 23 April (petal fall). The NAA or Pro-Ca application after trunk was pruned at dormant (TR-2 and TR-3) significantly reduced shoot growth in upper part of canopy compared with the control (tree was only pruned at dormant, TR-1), but the percent of shoots showing the secondary growth of TR-3 was higher over 2 times than that of TR-2. The reduction of shoot growth in upper part of canopy by TR-2 and TR-3 increased the fruit red color from the lower part in the treating year and blooming of the lower part in the following year. CONCLUSION: Applying 2.0% NAA to cut surface of pruned apple trunk at dormant was the most effective way for stabilization of the tree vigor in upper part of the canopy in a high density apple orchard.

최근 지구온난화 심화와 환경재난 등으로 석유유래 플라스틱의 분해에 대한 관심이 높아지고 있다. 플라스틱의 분해를 촉진하는 산화촉진제로 ferric ion(Fe²⁺)을 농도별로 첨가하여 필름을 제조하였다. 대조군으로 LLDPE필름과 산화촉진제를 농도별로 첨가한 필름에 UV를 시간별로 조사하여 인장강도, 신장율과 분자량변화를 조사하였다. 수지에 ferric ion 첨가량이 많아질수록 물성저하가 컸으며, 분자량 변화도 큰 것으로 나타났다. 인장강도는 대조군에 비해 산화촉진제 첨가필름이 조사시간 100시간 후 부터는 현저하게 저하되었으며, 이러한 현상은 신장율에서도 비슷한 것으로 나타났다. 분자량은 산화촉진제 첨가에 따른 결과로 UV 조사 50시간 후 63.6%, 100시간 후에는 73.8% 분자량이 감소한 것으로 나타났다. 이상의 결과에서 플라스틱 필름에 산화촉진제인 ferric ion(Fe²⁺)을 첨가함에 따라서 필름의 강도와 분자량이 저하되는 결과와 김 등 등의 보고를 바탕으로 필름의 분자량이 저하되면 그만큼 필름이 분해되고 있다고 판단할 수 있을 것으로 사료되었다.
