  • Our human society is rapidly changing into the world of advanced visual information with the development of image industry, the advent of satellite and terrestrial DMB, and the opening of Ubiquitous era. Like this, we are living in the space of overflowing media contents. Jean Baudrillad anticipated that the influential power of image would dominate our reality in 'Simulation'. Noticing the indication of our time, which is organized by various information media including the mass media, Baudrillad predicted that the 21st century would be an era of symbol and image due to the development of television, computer, and internet. This paper attempts to find the physical and conceptual peculiarities of the space change according to the use of display, by analyzing SF films, where future daily life is a major setting, under the judgement that the exploration of space change is significant. Through findings, it tries to lead the visual expansion, which recognizes display as space itself rather than object of space and changes unmoving space into moving space, and suggest the future space design by using digital space. It suggests case studies, which use digital display in the real space, as a study method and it examines the features, influences, and roles of digital display through investigating literatures and cases. In addition, it attempts to find a correlation of digital display and space by selecting films, which can give the affluent resources of analysis on the digital display among SF films. Therefore, it will come to a conclusion that space change should be dealt with in the space design.

  • This study describes the modeling of climate change impact on runoff across southeast Korea using a conceptual rainfall-runoff model TANK and assesses the results using the concept of environmental flows developed by International Water Management Institute. The future climate time series is obtained by scaling the historical series, informed by 4 global climate models and 3 greenhouse gas emission scenarios, to reflect a $4.0^{\circ}C$ increase at most in average surface air temperature and 31.7% increase at most in annual precipitation, using the spatio-temporal changing factor method that considers changes in the future mean seasonal rainfall and potential evapotranspiration as well as in the daily rainfall distribution. Although the simulation results from different global circulation models and greenhouse emission scenarios indicate different responses in flows to the climate change, the majority of the modeling results show that there will be more runoff in southeast Korea in the future. However, there is substantial uncertainty, with the results ranging from a 5.82% decrease to a 48.15% increase in the mean annual runoff averaged across the study area according to the corresponding climate change scenarios. We then assess the hydrologic perturbations based on the comparison between present and future flow duration curves suggested by IMWI. As a result, the effect of hydrologic perturbation on aquatic ecosystems may be significant at several locations of the Nakdong river main stream in dry season.

  • Climate change vulnerability assessment based on local conditions is a prerequisite for establishment of climate change adaptation policies. While some studies have developed a methodology for vulnerability assessment at the national level using statistical data, few attempts, whether domestic or overseas, have been made to develop methods for local vulnerability assessments that are easily applicable to a single city. Accordingly, the objective of this study was to develop a conceptual framework for climate change vulnerability, and then develop a general methodology for assessment at the regional level applied to a single coastal city, Mokpo, in Jeolla province, Korea. We followed the conceptual framework of climate change vulnerability proposed by the IPCC (1996) which consists of "climate exposure," "systemic sensitivity," and "systemic adaptive capacity." "Climate exposure" was designated as sea level rises of 1, 2, 3, 4, and 5 meter(s), allowing for a simple scenario for sea level rises. Should more complex forecasts of sea level rises be required later, the methodology developed herein can be easily scaled and transferred to other projects. Mokpo was chosen as a seaside city on the southwest coast of Korea, where all cities have experienced rising sea levels. Mokpo has experienced the largest sea level increases of all, and is a region where abnormal high tide events have become a significant threat; especially subsequent to the construction of an estuary dam and breakwaters. Sensitivity to sea level rises was measured by the percentage of flooded area for each administrative region within Mokpo evaluated via simulations using GIS techniques. Population density, particularly that of senior citizens, was also factored in. Adaptive capacity was considered from both the "hardware" and "software" aspects. "Hardware" adaptive capacity was incorporated by considering the presence (or lack thereof) of breakwaters and seawalls, as well as their height. "Software" adaptive capacity was measured using a survey method. The survey questionnaire included economic status, awareness of climate change impact and adaptation, governance, and policy, and was distributed to 75 governmental officials working for Mokpo. Vulnerability to sea level rises was assessed by subtracting adaptive capacity from the sensitivity index. Application of the methodology to Mokpo indicated vulnerability was high for seven out of 20 administrative districts. The results of our methodology provides significant policy implications for the development of climate change adaptation policy as follows: 1) regions with high priority for climate change adaptation measures can be selected through a correlation diagram between vulnerabilities and records of previous flood damage, and 2) after review of existing short, mid, and long-term plans or projects in high priority areas, appropriate adaptation measures can be taken as per this study. Future studies should focus on expanding analysis of climate change exposure from sea level rises to other adverse climate related events, including heat waves, torrential rain, and drought etc.

  • We study on the concept and reason of seasonal change that 164 university students have. Subsequently the concept types on the seasonal change are classified according to the characteristics and conceptual change after teaching on astronomy. All of the students were simply checked by the questionnaire of multiple choice and essay method before learning on the subjects. And then they answered to questionnaires of similar type after one semester. By the analyzed results, we classify it to three steps of hierarchical concept structure. The first step is the cosmic perspective that is related to the Earth's condition and motion. The second step is the influence of the Earth that is directly affected by the first step. The third step is observer's perspective on the Earth depending on the second step. Among the answers, the first step is prominent and second step is rare. The answers on the reason of seasonal change show some kinds of type which are 1st, 1-2nd, 1-3rd, and 1-2-3rd step. By the result, it is arranged in sequence like as 1-3rd>1st>1-2nd>1-2-3rd type. The lowest number of students was 2nd step of the Sun's altitude and duration of daytime in pre-test. However the students of 2nd step obtained more correct scientific concept on the seasonal change after learning on the subjects, and got the higher score in the post-test than in the pre-test. We found how much important the hierarchical structure on the reason of seasonal change is. As the results, second step on the learning of the Sun's altitude and duration of daytime essentially have to teach after first step. And then third step have to teach. At last, it is sure that the students can obtain the concept of seasonal change.

  • The purpose of this study is to investigate middle school student's conceptual change about Force and Motion by the courseware based on constructivism. It is well known to science educators that misconcrptions about physics concepts are hardly changed into scientific ones. So as to change student's misconceptions about force and motion, the courseware was developed through the analysis of students' conceptions. 20 students were tested before and after learning through the courseware. One of the questions was about the direction of force acting on the ball thrown in the air when it is rising, at the top, and falling. The other was about the magnitudes and directions of forces acting on a car when it is accelerating, in uniform velocity, and decelerating. The results are as follows: In case of vertical motion, all students had misconceptions before learning, but after learning 5 students(25%) have changed their ideas into scientific ones. In case of horizontal motion, 9(45%) out of 20 students who had misconceptions about force and motion have changed their ideas into scientific ones.

  • In physics education, the research on students' conceptions has developed in the discussion on the nature and the difficulty of conceptual change. Recently, mental models have been a theoretical background in concrete arguments on "how students' conceptions are constructed or created." Mental models that integrate information in the presented problem and individual knowledge in their long-term memory have important information about not only expressed ideas but also in the thinking process behind the expressed ideas. The purpose of this study is to investigate the forming process and the characteristics of high school student's mental models about circular motion, and how they were changed by instruction. We used the think-aloud method based on the instrument for identifying student's mental models about circular motion, pretest of physics concept, mind map and interview for investigating student's characteristics. The results of the study showed that instructions based on the mental model theory facilitated scientific expressed model, but several factors that affected forming mental models like epistemological belief didn't change scientifically after 3 lessons.

  • As the amount of informatization investment is rapidly increasing in many organizations, it becomes more inevitable to manage computing resources (information systems, computing facilities and manpower etc.) effectively. Specially, in public sector It is thought to be very important to achieve the economy of scale by integrating computing resources which are managed individually in many agencies. Also, our government have been recently making much efforts to raise the effectiveness of operating the information systems by promoting joint information use among many public agencies, enhancing the operating systems and the expertise of IS staff and applying the optimal information security systems. This study focuses on presenting the framework to effectively integrate omputing resources and proposing the ways of constructing and operating the integrated computing environment for the institutions and the affiliated groups under the Ministry of Culture & Tourism which are in charge of implementing cultural informatization. The main implications of this study are 1) building the ideal model of the integrated computing environment architecture suitable to cultural informatization area, 2) showing the criteria of deciding whether the organizations use the Integrated computing environment or not and how extensively they commit their computing resources to it, and 3) suggesting the ways of the phased integration and the change management to minimize confusion in the process of adopting the integrated computing environment and behavioral problems such as conflict and resistance of IS-related Personnel Influenced by Implementing the integrated computing environment.

  • The society, nowadays, is in a state of transition, and the family, which must always accomodate to society, is change with it. And because of transitional difficulties , the family's major psycosocial task has become more important than ever. That is , the family sill change. but it will aso reamin because it is the best human unit for rapidly changing societies. Under the circumstances, a healthy marital interaction is still the key to optimal family process, and the marital relationship is also the basis of the parental one. This paper aims to study an conceptual schema of family functioning chiefly concerned with marital relationship base d ton the family therapeutic psychology the systematic approaches of which have been recently developed. Subsequent to the importance of spouse functions and the characteristic of a functioning family the marital tension as a cause of marital problems and the theoretical approaches that will allow to deal with these problem , are also explained in this paper. On the otherhand, the sexual dysfunction, one aspect of a wider set of marital problems, and problems of dysfunctional children are not discussed in detail , because these problems shall become specialized fields. By this paper , it is expected to find a clue to the emotional and psycosocial aspects of marital problems, which will help us have a broader viewpoint in the study of family relationship.

  • The nature of work which is changing has increased the importance of HRD within organization. Also, these changes are making HRD shift its paradigm : from the segregated, closed, operational & administrative, dependent, utilitarian view to the integrative, open, strategic & facilitative, interdependent, generative view. The shifts of the perspective on HRD cause HRD professionals rethink the purpose and definition of HRD, and the role & competency needed to HRD in 21st century. The findings which are drawn through literature review and researcher’s intuition based on a long field experience are as follows. First, The function of HRD has recently been much more important then that of the past. Second, There is no consensus over the conceptual identity of HRD. Nonetheless, it is apparent that the preferred activities of the HRD function is performance improvement. Third, It is too difficult that we should define clearly the role & competency of HRD because of diverse perspectives on them. But we find much evidence converging to support the fact that the role & competency of HRD should be extended from the sole focus on training & development to adding the additional role & competency of change agent, who includes planning, implementing, and managing change.

  • Conception in learner's cognitive structure has a niche as species in ecosystems. The purpose of this study is to analyze the change of niche overlap of photosynthesis concept through instruction. The photosynthesis concepts were selected from literature review. Selected concepts were in 4 areas: Location of photosynthesis, reactants, products, and environmental factors. The subjects consisted 304 elementary students. The respondent marked the relevance between the presented concepts and each area on a scale of 1~30 points. The analysis of niche overlap in concepts was performed by changing in niche overlap graph, niche space size, and overlap index before and after instruction. The results are as follows. First, on the whole understanding level and relevance of the scientific concepts was increased through instruction as a result of learning. Second, elementary school students cognitive concepts in the form of chunking concepts through classification process. Based on the results, this study has the following suggestion. Students' conceptual ecologies and niche analyzed by this study will be used as material for development of instruction strategy.
