  • This study was designed to verify the influence of mothers on their young adults in pro-environmental consuming consciousness and behavior. The compiled data are based on the responses of questionnaires from 278 young adults who reside in Seoul, Korea. The data were analyzed by frequency, standard deviation, mean, unitary dispersion, rank revolution analysis, analysis of variance (ANOVA), and multiple regression analysis by SPSS 14.0K for Windows. This study has discovered the following: First. A mother's pro-environmental consuming behavior is one of the most important factors significantly influencing a young adult's consciousness and behavior. Second. A friendly and positive consciousness about the environment enhances pro-environmental consuming behavior. A close inter-relationship exists between consciousness and behavior. However, some significant discrepancy was found between pro-environmental consuming consciousness and pro-environmental consuming behavior; that is, the level of pro-environmental consciousness was higher than the level of pro-environmental behavior. Third. Sensitivity to environmental information influenced pro-environmental consumption consciousness and behavior. Female students are more concerned about and sensitive to environmental matters than are male students. Fourth. Among the subordinate dependent variables, recycling behavior is most influenced by independent variables. Among the pro-environmental consuming behavior sector, a mother's disposal behavior exerts the most influence on the young adult's behavior. In the results of this study, it is pointed out that it is absolutely necessary fur young adults to bring up their practice level of pro-environmental purchase and consuming behaviors, and it is advised that appropriate and relevant education programs should be developed.

  • The purpose of this study was to survey primary students' perception of the global and local environmental issues. The subjects were 853 fifth primary students in Seoul, Busan, Daejeon, Anyang, Gimpo and Cheongju. The results were as follows: First, the perception level of the global environmental issues were global warming (M=3.99), drinking-water pollution (M=3.92), acid rain (M=3.77), yellow dust (M=3.66), ozone depletion (M=3.57), deforestation in tropical areas (M=3.52), desertification (M=3.36), biodiversity (M=3.40) and their perception level of local environmental issues were waste disposal (M=3.87), air pollution (M=3.74), bad smell (M=3.70), noise (M=3.61), river pollution (M=3.57), soil pollution (M=3.44). Second, it was shown that the metropolitan students' perception levels of environmental issues were higher than the non-metropolitan students'. There wasn't a significant difference in the perception levels of two scale environmental issues and characteristics for sex (p>.05). Third, the result of analyzing on the effects between characteristics was that the factors like 'environmental interest' and 'impact on personal life' had a strong influence on the 'behavior will' to solve the global environmental issues, and 'environmental interest' and 'personal knowledge' had a strong influence on the 'behavior will' to solve the local environmental issues. Fourth, the result of analyzing on the characteristics according to the types of the environmental issues showed that 'personal knowledge', 'environmental interest' and 'behavior will' were high in the global environmental issues (p<.01) and 'virtual contamination', 'human responsibility' and 'impact on personal life' were high in the local environmental issues (p<.05).

  • The ammonia-oxidizing bacterial (AOB) communities in three membrane bioreactors (MBRs) were monitored for 2 months after an acclimation period in order to investigate the influence of sludge age and medium type on AOB changeability and its connection with nitrification effectiveness. One MBR with a sludge age of 4 days was fed with a synthetic medium, whereas the other two with sludge ages of 8 and 32 days were fed with landfill leachate. The research revealed that landfill leachate can be effectively treated in an MBR with a higher sludge age for longer periods of time and that this improvement in performance was correlated with an increase in AOB biodiversity. Interestingly, the medium type has a stronger influence on AOB biocenosis formation than the sludge age.

  • The feasibility of laccase production by immobilization of Pleurotus ostreatus 1804 on polyurethane foam (PUF) cubes with respect to media composition was studied in both batch and reactor systems. Enhanced laccase yield was evidenced due to immobilization. A relatively high maximum laccase activity of 312.6 U was observed with immobilized mycelia in shake flasks compared to the maximum laccase activity of free mycelia (272.2 U). It is evident from this study that the culture conditions studied, i.e. biomass level, pH, substrate concentration, yeast extract concentration, $Cu^{2+}$ concentration, and alcohol nature, showed significant influence on the laccase yield. Gel electrophoretic analysis showed the molecular weight of the laccase produced by immobilized P. ostreatus to be 66 kDa. The laccase yield was significantly higher and more rapid in the packed bed reactor than in the shake flask experiments. A maximum laccase yield of 392.9 U was observed within 144 h of the fermentation period with complete glucose depletion.

  • Common aquaculture practices include the use of certain pharmaceuticals such as antibiotics in avoiding diseases and promoting a healthier growth of the culture. The aim of this study is to monitor and assess the influence of different low oxytetracycline concentrations on the transformation of nitrogen compounds under aeration condition in a lab-scale recirculating aquaculture system (RAS). Over $1mg\;L^{-1}$ dose of oxytetracycline to aquaculture had induced ammonia($NH_4-N$), nitrate($NO_3-N$), soluble COD accumulation in RAS. In addition, nitrous oxide ($N_2O$) emission from RAS was significantly reduced during the oxytetracycline dose periods. After ceasing the dose of oxytetracycline, ammonia oxidation and nitrous oxide re-emission were observed. This observation indicated that low concentrations of oxytetracycline could affect the nitrogen species in RAS. Also, the emission mechanisms of $N_2O$ may not be only dependent on nitrification process but also dependent on denitrification process in our RAS system.

  • The purpose of this study is to investigate the direct and indirect modes of influences environmental dynamism exerts on opportunism, one of important relationship factors. This study particularly delves into the indirect modes of influence in terms of control strategy (control mechanism) and control structure (bureaucratic structuring). To this end, a survey research has been conducted of 200 suppliers in business relationships with Korean hypermarket retailers. An analysis of the collected data indicates that while environmental dynamism has a positive influence on the control mechanisms such as monitoring and incentives, it does not have a negative influence on the control structure such as participation. And then it has a positive influence on the opportunism of suppliers. In addition, participation has a negative influence on the opportunism, but monitoring and incentives do not have a negative influence on it. This study discusses how both retailers and their suppliers should respond to the domestic retail business environment with highly dynamic characteristics, in order to achieve a long-term win-win partnership with one another. It also presents ideas to retailers with regard to what kinds of management strategies and management efforts required to effectively control the opportunism of suppliers.

  • The purpose of this study was to examine the effects of a lifestyle consisting of a health oriented diet and personal motivation toward health improvement on an individual's desire to participate in condolence or "healing" -workshops and programs. In order to examine the influence of the "health diet" and motivation, the "health diet" lifestyle was classified into nutrition pursuit factors, psychological factors, food safety factors, and health conscious consumption factors. Personal motivation was categorized into perceived benefits, environmental factors and the individual's desire for happiness. Empirical analysis showed that nutrition pursuit factors had an impact on perceived benefits and the desire for happiness. Psychological aspect factors had a significant influence on perceived benefits, environmental factors and the desire for happiness. However, food safety factors and health conscious consumption factors did not have an effect on individual motivation to improve health. Regarding personal motivation toward health improvement on the desire for "healing", perceived benefits and environmental factors had significant influence. However, the individual's desire for happiness did not influence the demand for "healing". Regarding the effect of a "health diet" on the desire for "healing", only the psychological aspects of a "health diet" had any significant effects on the desire for "healing". The results from this study can help local organizations or service companies that provide "healing" programs with developing effective marketing strategies that could lead to greater customer satisfaction. Especially, the significant influence of psychological aspects of a "health diet" on the demand for "healing" is noteworthy in that this could play a key role in establishing a more effective marketing strategy to attract increasing numbers of consumers using health conscious diets.

  • This paper closely examines the relation between ‘how the local residents' involvement in a tourist industry and their perception of tourist development have an influence on tourism' and also 'how the understanding of a tourist effect has an influence on the local residents' participating intention in the tourist policy'. The local residents' involvement in the tourist industry was influenced by economical and socio-cultural factors among the influencing perceptions on local festivals, but, statistically, was not influenced by an environmental factor. The local residents' perception of tourist development has influenced on each local festival, and for the rate of influence, the environmental factor was the highest, and in the next order, the residents' intention to participate in tourist policy, the socio-cultural factor, and the economical factor followed. In the relation between local residents' perception of tourist influence and their participating intention, only the factor of socio-culture had a plus(+) influence on the participating intention in the tourist policy. It is expected that this result will be different from the tourist influence of tourist development. Therefore, a study of the perception on the influence of tourist development will be required in the future.

  • The influence of the point source inflow on the water quality variation in the downstream of Hyeongsan River was investigated. As the results of seasonal variation, the pollutant concentrations of dry season were 1.5-4 times higher than those of wet season. The increase rate of $BOD_5$, $COD_{Mn}$, T-N, T-P due to point source were ranged to $8.1\sim42.6%$, $7.3\sim41.9%$ and $17.1\sim207%$ as the inflow of P1, P2 and P3, respectively. After P1, P2 and P3 inflow, the accumulated increase rate were 64.3%, 32.6%, 93.1% and 258.9% in $BOD_5$, $COD_{Mn}$, T-N, T-P, respectively. It was found that the influence of point source inflow on the water quality in the downstream of Hyeongsan River is severe.
