    전상미 | Park,Jae-Hyeon | Park, Chang-kun | 2012, 8(6) | pp.51~65 | number of Cited : 1
    Abstract
    Small & medium-sized urban streams, in line with the changes to the characteristics of hydraulic factors such as increasing use of stream water and groundwater near the river or stream and variation in land use, has been suffering streamflow depletion, making it worse the healthy environment of the river. This study is intended to evaluate the hydraulic factors influencing on streamflow depletion so as to propose the quantified evaluation indicators which will enable to easily evaluate the degree of streanflow depletion. To that end, Namcheon where the streamflow depletion has been accelerated due to increase in impervious area ratio and groundwater use in line with urbanization. Analysis of discharge duration curve by subwater shed which was developed using SWMM_GE program which is the long-term flow program using hydraulic data for the regions and integrating the groundwater level and stream river level based on rainfall data for past 10 years. To evaluate the effect on streamflow depletion by cause, flow variation characteristics by hydraulic factor was analyzed and for evaluating the degree of ongoing streamflow depletion, a quantified standard flow based on mean drought flow before urbanization was proposed. In the wake of applying such indicators to the regions, Namcheon basin area was at category 3 under natural condition which is considered to be average or good, but at current condition, it belongs to category 5 which falls into very unfavorable condition. Evaluation approach and indicators proposed in this study are expected to make commitment to analyzing the instreamflow of urban river and water improvement policy.

    Application of Technique for Evaluating Streamflow Depletion in the Urbanized Small and Midium Watershed: Gyeongancheon, Wangsukcheon

    전상미 | Park,Jae-Hyeon | Park, Chang-kun | 2012, 8(6) | pp.67~81 | number of Cited : 4
    Abstract
    Runoff characteristics of the urbanized watershed was affected by some urbanized factors including the increasement of unpermeable area, groundwater use, and the deceasement of groundwater level, so as the results, the stream depletion was increasing. In this study the stream depletion assessment method, which is to evaluate the depletion of the urbanized small & midium watershed stream, was suggested. To apply the streamflow depletion evaluation approach proposed in this study, Gyeongancheon and Wangsukchon were designated for investigation and using SWMM_GE program, long-term runoff characteristic was evaluated, and depth of streamflow depletion was evaluated using standard flow and evaluation indicators. In most of cases, the higher the impervious area ratio the more the flow during wet season and the less the flow during dry season. When it comes to the change by groundwater use, the flow tended to decrease regularly both during wet season and dry season. When it comes to the direct cause of streamflow depletion such as stream water intake, reservoir operation and sewage treatment plant, variation of flow and effect on depletion may be significantly different by scale of each factor. Based on flow characteristics in the region, standard flow was estimated and the depth of streamflow depletion was evaluated using evaluation indicators. As a result of evaluating of the depth at natural condition, category was distributed from 1 to 5 and mostly within 3 which resulted from changes to natural environment and the degree of streamflow depletion would not be significant if no artificial environment change occurred. The depth was various from category 1 to 5 indicating very low condition when considering impervious area ratio and groundwater use. However when considering the direct causes, the effect was various depending on location and scale of reservoir and sewage treatment plant.

    A Development of Korean and US University Consumers’ Food Safety Attitude-Behavior Model

    Hyun-jung Yoo | 2012, 8(6) | pp.149~169 | number of Cited : 14
    Abstract
    For safer society of food, it needs two food distinct components: safety system and consumers' food safety oriented behavior. In addition, it is essential to comprehend a global standards of food safety and global consumers’ behavioral characteristics because we need to lean to other countries for food as our lack of foods. We surveyed a consumers’ food safety awareness, attitude, and behaviors of food safety in the South Korea and US. We developed a food safety attitude-behavior scales and measured them. Finally, we made a food safety attitude-behavior model by using a structural equation model. The research results are below. First, Korean consumers have high awareness and attitude of food safety, but they have relatively low food safety behaviors. However, US consumers have high food safety behavior as compared with food safety awareness and attitude. It let us know that US consumers practice a food safety behavior more habitually as compared with Korean consumers. Second, US consumers are concerned about hazard factors like as food poisoning bacteria or cancer-causing agent but Korean consumers are concerned about unsafe factors of foods which could be caused from production, manufacturing, retailing them. Confidence for food safety is higher in US as Korea. Third, from the structural equation model findings it was shown that food safety awareness influences attitude and attitude influences behavior. However, the effect from attitude to behavior was not significant directly.

    이영철 | 송윤석 | 2012, 8(6) | pp.171~182 | number of Cited : 0
    Abstract
    When researches the number of fires that occurs annually, most fires are broke out small buildings such as townhouses, multi-family houses, model houses, and small private houses that are not fully reached fire protection and relevant regulations. And the numbers comprise majority of fires per year. In many cases, these small buildings are exempt from a series of fire protection systems or acquired very limited properties only. One of the examples of limited fire protection (alarm) system is installation of electrically operated single detector. Identifying problems in installation, we proposed the wireless combinational single detector by the alarm method which informs whole floors. It contributes to protect a loss of lives and heavy economical loss by a fire.

    The Effect of Police Activity on Fear of Crime: Hierarchical Model Approach

    Ryu Junhyuk | 2012, 8(6) | pp.211~234 | number of Cited : 16
    Abstract
    In general, the study of fear of crime was commonly analyzed in three influential models that include crime victimization model, disorder model, social integration model. With several hypotheses about police activity model, this study examined the effect of four models on fear of crime. On the basis of survey data on 1,230 randomly selected at Daegu, Hierarchical Linear model analysis found that the effects of gender and victimization experience are positively related with fear of crime. This study also found that police patrol presence originated from classic deterrence theory can decrease fear of crime among police activity variables. In addition, community policing strategies appear to demonstrate the impact of fear reduction. At macro level, while community disorder does not have any influence on fear of crime, social integration is negatively related with fear of crime. In conclusion, this study suggests several policy implications.
