Risk communication can be defined as the exchange of information about the nature, magnitude, significance, acceptability, and management of risk. The effect of risk communication on the perception and knowledge towards risk of environmental pollutants and it's related factors were investigated in this study. To investigate perception and knowledge of students and teachers towards risk of environmental pollutants, we conducted the survey using self-administrated questionnaire. The subjects were 574 for the first survey and 465 for the seconds survey from May to June, 2000. The main methods of transmission used in this study- through video tape, visual materials, question and answer, and participation in measuring pollutants - were not a one - way street. But an interactive process where information and opinions were exchanged among individuals, groups, and institutions. Environmental pollutants measured with participation of study subjects was Radon in the class room. The concentration of Radon was measured using E -PERM Device by installing it at each site for about 5 days. Subjects showed much interest in environmental pollution. Also, more than 98％ of total subjects were perceived as Korea is seriously contaminated at present. By risk communication activity, risk perception of all subjects about Radon was increased, on the other hand, risk perception of Dioxin was decreased except for elementary student. Moreover, knowledge of all subjects about environmental risk was significantly increased (p =0.0001) and effort of reducing environmental pollution was more increased (p<0.05). There is need to further develop, refine, and integrate these approaches environmental risk communication study, there is an even more pressing need to accelerate the diffusion of environmental risk communication practice into government and organizations.

Effective communication flow is a fundamental for the success of any construction projects. The key role of communications among project parties is even more critical in the case of Design-Build (DB) projects. Previous research has shown that these projects have an environment where integration between different project team members and schedule constraints increase channels of communication, and require faster communication flows. This paper summarizes the findings from research analyzing organizational structures and communication flow of the Texas State Highway 130 (SH130) project. Awarded in 2002, the SH130 project, totaling $1.3 billion USD, constitutes the "pilot" application for the DB approach in the state of Texas. A set of observations pertaining to team organization and communication issues in the design-build environment is included.

With the methodology of AHP, this paper focuses on communication activities and their constituents in city parks, selecting 11 constituents, natural or artificial, and establishes an evaluation model on the basis of the analysis of the characteristics of tourists' communication activities in order to obtain the weight and order of importance of the constituents of communication activities space. First-grade indicators influence weight and the order of the constituents of communication activities space are: artificial constituents (0.6614) > natural constituents (0.3386). The weight and order of five secondary indicators attached to natural constituents: private space (0.1538) > shade tree (0.0955) > gentle slope mound (0.0474) > beautiful waterscape (0.0270) > sunshine lawn (0.0149); the weight and order of six secondary indicators attached to artificial constituents: field boundary (0.2865) > Leisure chairs (0.1843) > resting areas (0.0795) > appropriate square (0.0533) > tree-lined road (0.0352) > landscape sketch (0.0227).Using modern decision analysis methodology to research the relationship of environment constituent elements has great theoretical and practical significance for the scientific design and construction of suitable environment for human needs.

Objectives: The purpose of this study is to obtain basic data on the development of a risk communication model through an investigation of risk perception for radon and identify effective risk communication channels. Methods: A questionnaire was used to evaluate differences in perception level according to respective communication channels. A chi-squared test was used to analyze the difference in pre- and post-risk communication by communication channel. One-way ANOVA was used to analyze the difference in the radon risk perception rate for each communication channel. Results: All of the communication channels resulted in increased radon risk perception, but there was no statistical difference between them in terms of perception (p>0.05). However, based on previous findings that it is effective to use a multi-channel approach, it is considered that communication channels based on duplicate avenues is most appropriate. Conclusions: It is expected that this study will be used as basic data to better understand the formation of public opinion about radon risk and to understand the social reaction to each risk factor.

In this paper, we described a design and implementation of a sensor node for environmental monitoring. The main focus of design for sensor nodes is to isolate MCU for treating sensors from the RF module for considering various communication environment. The second is to make the interface between MCU and varity of sensor. In addition, we choose a narrow band communication module, cc1020, for the admittance of Korea government communication law. We also use a uC/OS-II as an operating system which is famous for 8bit MCUs. We showed that the communication performance is sufficient to use the communication module in a out-door environment through several experiments in that it is possible to transmit between 100m distance through experiments in a mountain.

The goal of this study was to establish the evaluation method, which consist of the principle, factor, procedure and checklist, on environmental camp program and then to support staffs of environmental camp for decision-making to improve pre-program and develop new one. The main principles of the evaluation method established in this study were Hierarchical holism and Open inter-communication. First, hierarchical holism focused at the interaction among six factors, which were divided by 3 steps : 1) goal(and objectives) 2) learners and sites 3) activities, staffs and media. Second, open inter-communication could be defined a feedback process among all program participants : manager, staff, teacher, volunteer, learner and so on. The evaluation checklist had been developed of 10 comprehensive items and 30 factor-items at the preliminary step but some items were assessed some complex or duplicate in the result of 3 case studies. The suggested checklist was diminished to 5 comprehensive items and 25 factor-items. Several alternatives, which included specifing learners and objectives, developing site-oriented program and establishing the evaluation sheet were suggested for improving environmental camp program.

Objectives: The aim of this study was to suggest preliminary data for the establishment of communication methodology of asbestos risk, fit for the features of each audiences, by grasping the features of risk communication by each element for each group survey. Methods: For this study, a questionnaire survey has been conducted from May to August 2012 and responses of 617 people including 214 school asbestos managers, 95 asbestos business managers, and 308 general public have been analyzed. Results: The feature by element of risk communication shows that to give information through non-governmental organizations with reliability such as colleges, research institutes, asbestos-related associations, etc among the entire investigated groups, is most effective. Lastly, for stakeholders related to asbestos, the public feedback for governmental asbestos management policy shows that it was considered that there is lack of reality due to comprehension deficit for situation, lack of a system of asbestos general management in the country and lack of policy connectivity among the branches of the government, and between the central government and the local government. However, the general public selected lack of various information disclosure, education, publicity for asbestos and lack of communication with citizens as the biggest problems.

Honey is one of the most significant ingredients in conventional food production in different regions of the world. Honey is commonly used as an ingredient in ethnic food. Beekeeping is performed in various locations as part of the local food culture and an occupation related to pollinator production. It is important to conduct beekeeping so that it generates food culture and helps regulate the regional environment in an integrated manner in preserving and improving local food culture. This study analyzes different types of environmental factors of a smart bee farm. The major goal of this study is to determine the best prediction model between the linear regression model (LM) and the support vector regression model (SVR) based on the environmental factors of a smart bee farm. The performance of prediction models is measured by R² value, root mean squared error (RMSE), and mean absolute error (MAE). From all analysis reports, the best prediction model is the support vector regression model (SVR) with a low coefficient of variation, and the R² values for Farm inside temperature, bee box inside temperature, and Farm inside humidity are 0.97, 0.96, and 0.44.
