The purpose of this study was to examine the perception of students about pseudo-science in consideration to their personality traits, cognitive style, and awareness of the nature of science, which might all have a great impact on their behavior and thinking. The subjects of this study were 129 sixth-grade school children in a small urban community in Gyeonggi province. The way they looked at pseudo-science was investigated after three kinds of traits were selected as variables, including personality traits, cognitive style, and awareness of the nature of science. Four different instruments were utilized, which respectively covered personality traits, cognitive style, awareness of the nature of science and perception of pseudo-science. The results of the study were as follows: First, the children with higher emotional stability and liveliness showed higher permeability towards pseudo-science, while made no significant difference on their view of pseudo-science. Second, their cognitive style made no significant difference to their outlook on pseudo-science. Third, as for link between awareness of the nature of science and pseudo-science, the students with a poor understanding of the nature of science were significantly different from those who had a better understanding of it in perception of pseudo-science(p<.05).

The purposes of this study were to investigate the influence of local residents' nature environment attitudes for National Park development impact perceptions and to examine application possibility of nature environment attitude for resolution information of National Park management conflicts. Thirty items of residents' perceptions and opinions were designed from previous tourism impact studies. The new environmental paradigm(NEP) was used to measure local residents' nature environment attitudes. In April, 2003, 239 questionnaires were obtained from interview survey in local residents' villages near Gyearyongsan National Park. Generally, most of the local residents perceived low economic effects and negative environment impacts for National Park development. Nature environment attitudes levels were significant differences with socioeconomic variables of local residents, specially high in age, education level and influenced their perceptions toward National Park development impacts. The results were suggested that the nature environment attitudes could be provided a useful reverential framework in resolution of National Park management conflicts.

Recently, there are getting popular form generation-related design methodologies and scientific discourses about the nature of nature in the environmental design. The necessity of visual perception and cognitive research is growing in this respect. Accordingly, this study was designed to discuss environmental design and cognition in the ecological perspective. This study was intended to study the structural factors of cognitive ecological space. This study focused on the systematic principle of new environmental design based on cognitive ecological approaches and what kinds of design effects this design principle has on the human being in the long nm. The results are as follows. First, the results suggests that fractal pattern should be an alternative to design cognitive ecological space and new paradigm of architecture is based on the nature of nature and human sensibility. Accordingly, they have proposed that fractal design is more empirical and environment-friendly than rational linear design. Second, this study classified the variables of cognitive ecological space into nature, tradition, preference judgement, aesthetic value, and schema. Accordingly, such features as symbol, tradition, and nature restricted by modernistic ideology should be added to new paradigm-based environmental design. Third, accordingly, this study stresses that cognitive ecological environmental design doesn't include buildings of modernism and deconstruction and is based on new science of complexity.

Due to the nature of the construction industry, massive and diverse data is generated and collected from each project. It can be classified into a number of variables that specify the distinct characteristics of construction projects. However, a variable is used in different terms depending on the users. This situation plays as a great barrier to effective construction information management and also has limitations to collective research and practice. As a solution, it is essential for developing common and shared variables. In this context, the aim of this study is to define systematically organized standard variables for globally collaborative construction management. The standard variables are identified by bibliometrics analysis with VOSviewer, and the bibliographic data is collected from the Scopus with 13,533 documents about construction management.

Simplified techniques based on in situ testing methods are commonly used to assess seismic liquefaction potential. Many of these simplified methods were developed by analyzing liquefaction case histories from which the liquefaction boundary (limit state) separating two categories (the occurrence or non-occurrence of liquefaction) is determined. As the liquefaction classification problem is highly nonlinear in nature, it is difficult to develop a comprehensive model using conventional modeling techniques that take into consideration all the independent variables, such as the seismic and soil properties. In this study, a modification of the Multivariate Adaptive Regression Splines (MARS) approach based on Logistic Regression (LR) LR_MARS is used to evaluate seismic liquefaction potential based on actual field records. Three different LR_MARS models were used to analyze three different field liquefaction databases and the results are compared with the neural network approaches. The developed spline functions and the limit state functions obtained reveal that the LR_MARS models can capture and describe the intrinsic, complex relationship between seismic parameters, soil parameters, and the liquefaction potential without having to make any assumptions about the underlying relationship between the various variables. Considering its computational efficiency, simplicity of interpretation, predictive accuracy, its data-driven and adaptive nature and its ability to map the interaction between variables, the use of LR_MARS model in assessing seismic liquefaction potential is promising.

One of the components that constitute the simulation models is the state variables whose values are determined by the time related simulation process. Embedding rule-based expert systems into the simulation models should provide a systematic way of handling these time-dependent variables without distracting the essential problem solving capabilities of the expert systems which are well suited for expressing the decision making function of complex cases. The expert system, however, is inefficient in dealing with the time elapsing characteristics of target system compare to the simulation models. To solve the problem, this paper provides an interruptible inference engine whose inferencing process can be interrupted when the variables' value, which are used as the parameters of the rules, are not yet determined due to the time dependent nature of the state variables. The process is resumed when the variables are ready. The elapse of time is calculated by time-advance function of the simulation model to which the expert system has been embedded. The example modeling shown exploits the embedded interruptible inferencing capability for the controlling and monitoring of metal grating process.

This study investigates how motivations, preferences, and past experiences vary by each hikers trail choice at the Mt.Keyryong National Park. The purpose of this study is to find out the factors influencing behavioral choice in the recreation areas, and establish the fundamental theory for the efficient management of the resource and visitors. For this study, we have collected 472 respondents by on-site self-administrated questionnaire from the hikers in the park. The collected data were analyzed by the descriptive statistics and the discriminant analysis. The motivations variable of hiking participation on mountain trail were categorized three types; close-nature, escapism, and physical improvement. The preferences for trail environment were classified as four categories by factor analysis; preference for nature, safety, use density, and facilities. In descriptive statistics, the study showed that the experienced hikers prefer natural trials and hikers who have preference for close-nature select longer and deeper forest trails. The results of discriminant analysis indicate that the level of past experience is the most affectable in classification of trail choice. Such variables as motivation for close-nature and preference for nature were also appeared as affecting factors on classification of trail choice. Two discriminant functions were available, and 90.5 percent of analysis sample were correctly classified. In the validity analysis, 89 percent of holdout sample were correctly classified. These hit ratios ensures an accuracy by Press Q test. The result of this study is to be useful knowledge of the choice of detailed use environments in the same recreation areas.

With the widespread use of smartphones and the development of information technology, an online service called SNS(social network service) has emerged, and as an increasing number of people began to use SNS, extensive research has been conducted on SNS. SNS is an important factor for adolescents who are developing social skills that help them to adapt to the society, and for adults who are stepping into the society. The present study investigates the effects of information search, self-disclosure, interaction, and playfulness, all of which are motivational factors for SNS use, on flow in SNS, and empirically analyzes the degree of these variables influence according to flow in SNS and individual's personal nature(extrovert, introvert). The analysis results showed that information search, self-disclosure, interaction, and playfulness were positively correlated with flow in SNS, and flow in SNS was positively correlated with social skills. The degree of influence varied depending on the individual's personal nature(extrovert, introvert). These findings may provide important insights for researchers studying SNS, SNS managers, and company officials using SNS.

Most of the theories of collective bargaining outcomes start with a set of economic variables. The economic constraints, pressures, and incentives influence the bargaining power relationship between labor union and employer. In this paper, the critical macro and micro economic variables that need to be considered in analyzing the economic context of collective bargaining power relationship is outlined. The focus is on the role that economic forces play in shaping the results of bargaining, that is the outcome of negotiations. In this study, the elasticity of the demand for labor is introduced as one of the most important economic aspects that influence bargaining power. Unions will be most successful in increasing wages when they enjoy an inelastic demand for labor. If the demand for labor is not naturally inelastic, some institutional arrangement for "taking wages out of competition" must be sought. Inflation, business cycle, and income policy are influential in shaping both parties' goals and expectations as well. In addition to the analysis of the economic variables, the nature of power is diagonized with some introductory notions about its care and feeding before proceeding to the details of the above issues.
