This study aims to explore patterns and characteristics of coordination between evidence and theories which were found in pre-service elementary teachers' writing for their science inquiry. Five science inquiry activities and a total of 115 writings of the participant teacher at the elementary teacher preparation university in Korea were collected and analyzed for this study. Based on the writing analyses there were found four types of coordination between the evidence and theory. We proposed four types as: Type 1-Consistency of evidence and theory; Type 2-Consistence of evidence and theory including more extension or elaboration of theory; Type 3-Inconsistence of evidence and theory Type 4-Inconsistence of evidence and theory followed by coordination of them. Firstly the findings indicated that the most to least frequent types were Type 1, Type 3, Type 2, and Type 4. The most frequent type was Type 1. It is interpreted that theory in the inquiry questions were frequently figured out by participants and they selected supporting evidence out of data found. There were rarely found relations between activity topics and frequencies of coordination types except in activity 1. The findings in this study will connect to the point of how students collaborate their previously owned knowledge with experiment planning, data analysis and interpretation and making of their own scientific claims.

Recently, it is appearing that new paradigm of urban planning that ubiquitous concept such as the u-City, uECO-City is introduced while is rising necessity about third dimensional geo-spatial information of high quality for urban area. Orthophoto can manufacture by expense and time that is less easily than digital map using personal computer even if is not highly technician and according as position relation between manmade feature and natural feature is equal, can get information of distance, angle, horizontal and vertical position coordinate of topographic, area etc.. directly through orthophoto. Also, visual effect is good that orthophoto is expressed by image and interpretation is easy to detailed part of topographic. Manufacture and practical use are consisting in various field, for it is having advantage that can recognize information effectively than digital map. Therefore, this study presents a way of generating a detailed DSM for producing a true-orthphoto of the urban area, and this study also presents a way to produce an optimum true-orthophoto for an urban area by investigating through experiment the optimum variable for the geometric and radiometric correction of the orthophoto. This study also examined the potentials of the thesis by building a 3-dimensional city model of the model region with the above thesis on optimum generating method.

This research proposes a suitable classification and analysis standard for digital exhibition to analyze digital exhibition. Through the previous studies on digital exhibition classification, the necessity of the new standard is suggested and the analysis standard which can be easily applied to the change of concept and form of the newly emerging digital exhibition is established. Digital exhibition should take into account the elements of audience participation that naturally arise from exhibition planning and interactive storytelling format. Classification and analysis of existing digital exhibition spaces are conceptual classification based on keywords. This is because traditional exhibition methodology has been applied in the process of classifying exhibitions and works. However, in digital exhibitions, the interactive aspect between exhibition space, works, and visitors become so important that it is necessary to perform a performative classification between the works and the audience in the digital exhibition. Accordingly, the way of participating directly or indirectly in the exhibition classification should be considered based on what the audience feel. In this research, the interpretation of the classification and composition of the exhibition is based on Benjamin's argument which the classification of the sensory experience of the audience and 'Aktualisierung' closely related to the interaction with the audience. We also present analysis standard for digital exhibition according to the structure of the art exhibition narrative based on the narrative structure of Chatman. This classification methodology will provide the exhibition information in a way that can be easily understood by the visitors and it will be a precedent research that secures the expansion and accessibility of the digital exhibition.

This study was conducted to suggest alternatives for the effective use of national park visitor centers, by evaluating their functionality. Visitor centers in Naejangsan National Park and Pukhansan National Park, which are deliberately composed and managed, were investigated for this purpose. First, I clarified the concept, function and type of a visitor center through literature review, and then, analyzed visitors' post-visiting evaluation based on McManus's Communication Theory. The results of the analysis shows that visitors have not enough time to understand the contents of visitor centers, and facilities and guide sign system to support visitors are insufficient, which seem to disturb the proper communication between visitors and exhibits. Visitors' short visiting time caused by their little interest in exhibits and their low degree of understanding show the difficulties in the communication between visitors and exhibits. The following alternatives are suggested to improve these problems: first, the improvement of the guide sign system; second, the provision of exhibition rooms specialized for different visitor groups; third, the display of exhibits connected with visitors' experiences; Forth, the utilization of various media proper for each subject.

Cultural remains distribution maps have been published in 172 volumes of books, and the information about the remains in South Korea is also disclosed via the Internet to those who are interested in conducting archeological examinations or to those who are planning the national land use for various purposes. The purpose of this study is to statistically review the locational characteristics of the sites appearing in cultural sites map, and to determine the locational characteristics of these remains or sites. The location of sites was statistically analyzed based on the point density function of geographic information system of 87,859 sites found in cultural site maps. The results of this study show that the sites found in South Korea are mainly distributed around historical cities and the distributions are closely related to their proximity to rivers. Given that the period of time and type is very important to archeological studies, the results of this study indicate that detailed period of time and type may be necessary for further analysis. This study has highlighted that the research into the spatial analysis and interpretation of cultural heritage sites can contribute to the field of archeological studies.

The main reason of marine casualties is the human error in respect of ship's operation. The human error of officers in charge of a navigational watch is related to their abilities to handle of navigational equipment. Navigational devices play a key role to help officers decide what to do for safe navigation. Thus, the abilities to handle of navigational equipment mean not only operation of devices but also entire understanding of the system such as interpretation of information obtained from devices, appropriate use of information considering navigational circumstance. Qualification of seafarers is in accordance with STCW and detailed training courses for their qualification are provided by IMO model course series. Recently, ships engaged on international voyages shall be fitted with an ECDIS not later than the first survey on or after 1 July 2018. As increasing use of ECDIS on ships, marine casualties related to ECDIS are on the rise. The primary causes of the accidents are lacking understanding of ECDIS system, wrong presentation of information on display, wrong safety setting by seafarers who use ECDIS, using small-scale chart and missing charts update. As a result of these primary causes, some problems like wrong route planning and use of limited or omitted information occur. It could be happening by inappropriate seafarers' training which is not sufficient to support improving abilities of officers to handle navigational equipment. For efficient training, it is need to develop training courses. Applying full mission simulation system to seafarers' training courses with case studies and best practices which are well-constructed scenarios based on true marine casualties can increase the effect of training. To use the simulation system, it is possible that seafarers are trained under condition that closely resemble real situation. It should be considered that IMO model course be revised depending on the level of seafarers also. It could be helpful for increasing seafarers' abilities of equipment operation in place of accumulation of experience spending much time. In the short term, effort of training courses improvement for seafarers is needed and long term, it should be tried to provide stable system and services relate to ECDIS.

In order to predict the performance of biological wastewater treatment plant, the kinetic parameters and stoichiometric coefficient must be known. The theories and experimental procedures for determining the biological kinetic parameters were discussed in this study. Respirometric analysis in the batch reactor was carried out for the experimental assessment of kinetic parameters. A simple procedure to estimate kinetic parameters of heterotrophs and autotrophs under aerobic condition was presented. The difficulties in the interpretation of COD and VSS measurements encouraged the conversion of respirometric data to growth data. Maximum specific growth rate, yield coefficient, half saturation constant and decay rate of heterotrophic biomass were obtained from OUR(Oxygen Uptake Rate) data. Maximum specific growth rate of autotrophic biomass was obtained from the increase of nitrate concentration. The aim of this paper is to estimate the kinetic parameters of heterotrophic and autotrophic biomass by means of the respirometric analysis of activated sludge behavior in the batch reactors. These procedures may be used for the activated sludge modeling with complex kinetic parameters.

This study is dealing with Deoksugung around the founding of the Daehan Empire Era. It will looks closely into how locational contexts and sense of place have been changed according to the subject's view point and the interpretation of text community until Deoksugung is changed into citizen-oriented public place vested with the meaning of public park. In conclusion, Deoksugung was a place for suffering and sorrows, but also it was a place for ceaseless attempt to pursue of the recovery of past without loosing hope. As in the case of uprising war like Japanese invasion of Korea (Imjin Yeran) or Cheong Japan War, Deoksugung was an importantly historical place where autocrat temporarily stayed to stand up for the war and moreover, it was an imperial palace where the ambivalent sensibility between suffering and hope are intermingled in the very first Korean Empire in history. Unlike Kyeongbokgung and Changdeokgung, the current Deoksugung has changed its boundary from time to time since Japanese invasion of Korea up to the present. Deoksugung has evolved the present situation as endlessly changing its boundary by interacting with the neighbor of Kyungungung. The more complicated sense of place is coexisted in the features of the Deoksugung. Therefore, current hot topics concerning restoration project of Deoksugung is much more difficult than of other palaces. This issues should be carefully dealt with beyond the political interests.

This paper describes a development of system that enables the user to simulate the rockfall and landslide from slopes using physical engine. Until now, it will not be able to accomplish the virtual experiment of three-dimensional interpretation about slope informations, stability evaluation, the rockfall and landslide simulation, etc., because of absence of three-dimensional simulation systems which relates with slopes. With like that reason, this paper developed a simulator which is identical or similar the rockfall and the landslide where the possibility which will occur or occurred from actuality is high very actual condition from virtual experiment. For a simulator development, this paper uses the physical engine which is mainly used from computer game and animation development etc., And it will be show the process where the rockfall and landslide occurs with simulator. This simulator which sees the process where the rockfall and the landslide occur from three-dimension computer graphics theory and the physical engine, is a system which is the possibility of showing actual feeling. Therefore, the result of this paper is applied in vehicle travelling guidance system and intelligence traffic systematic etc., because of creates visual service and three-dimensional application of the slope information database which is developed in existing, and will be able to forecast the upgrade of user benefit planning and a service.

The purpose of this study is to present types of design concept based on the specificity of landscape design, and to derive a theoretical framework for the landscape design concepts by analyzing the design concepts appearing in urban park design competitions. Through literature review, five types of landscape design concepts were categorized into value and vision, analysis and interpretation, form and structure, program and element, and process and operation. Using this framework, the design concepts shown in 96 works submitted to 18 domestic and overseas urban park design competitions were analyzed. The results of the analysis are summarized as follows. First, due to the complexity of contemporary urban parks, design concepts are presented as mixtures of main concepts and secondary concepts in multiple layers. Second, it was identified that design concepts of 'form and structure' were used the most in urban park designs, followed by the 'program and element' concepts. The 'value and vision' and 'analysis and interpretive' concepts are introduced as third and fourth. Third, the reason that the 'form and structure' concept is widely used as main and secondary concepts is judged to be because the form of a space, which is the key result of the design, has an important influence on the identity of the design. Fourth, the reason that the 'program and element' concept type is widely introduced is that urban park design has a stronger planning aspect to produce programs during the design process, compared with other design fields where programs are usually given in advance. Lastly, it is difficult to see that the properties of the site solely affect the type of design concept, because a design concept is the result of a complex and creative process in which a designer subjectively interprets the objective characteristics of the site and project, and given design guidelines can affect the type of design concept.
