As the influence of Landscape Urbanism has grown, various criticisms on the discourse also have increased. A study on critical opinions of Landscape Urbanism is necessary to fully comprehend the theoretical structure of the discourse and its limitations. This study introduced the concept of Intension and Extension, which is used in the field of Logics and Semiotic, as an analytical tool to interpret various criticisms based on different views in a more objective and synthetic way. After examining the development of criticisms of Landscape Urbanism, 30 texts with important critiques on the theory were selected and analyzed. Criticisms can be classified as internal criticism and external criticism according to specific topics they are engaged with. The study only covers internal criticism as a research scope. The internal criticisms on Landscape Urbanism are re-categorized into topics of theory, practice and the relation between theory and practice. Vagueness of concepts and error in concepts are two types criticism related to the issue of theory. Lexical Ambiguity and Intensional Vagueness are the main causes of conceptual vagueness in Landscape Urbanism. Conceptual vagueness related with the problem of redefining an existing concept through expanding its meaning reveals a structural dilemma. There are three types of criticism included in the topic of practice: absence of practical results, form-oriented practice, and ambiguous identity in practical results. Ambiguous identity is caused by Extensional Vagueness allowing borderline cases. Because these borderline cases overlap with extensions of landscape architecture, it is hard to differentiate projects of Landscape Urbanism and those of conventional landscape architecture. Most criticisms on the relation between theory and practice raise the question on the practical method. Two types of criticism are engaged with the topic of the practical method: errors in practical methods and absence of practical methods. The absence of practical methods is a fundamental problem of Landscape Urbanism which is hard to solve by the proposed solutions. However, these structural problems are not only the weak point but also the factor that is able to prove the potentials expand the scope of Landscape Urbanism. In addition to the results of the study, internal criticisms on Landscape Urbanism should be examined in the following studies in order to predict the next direction of Landscape Urbanism.

The purpose of this study is to investigate the method on improving the frequency of use and satisfaction rate of the community facilities and to evaluate relation between improving the frequency of use and satisfaction rate of the community facilities and improving the sense of community in apartments. The research subjects of this study is the four public lease apartments which is built around same period with same design guide. The survey method is a questionnaire survey, a experimental study, focus group interview, an analysing drawing. The result of study is as follows. The first, the frequency of use and satisfaction rate have been effected by the operation management system as well as the physical circumstance. The second, The frequency of use and satisfaction rate of the community facilities have had positive correlation with sense of community. The third, multimedia room and conference room with low usability need to change a multipurpose space such as cafe, classroom for learning on artistic topic with high demand from occupant. Finally, a mindset shift is required for architects to inspire community facilities as an important mediated space improving the sense of community by suggesting spaces for leisure and hobby activities.
This literature review explores relevant research and evaluation on pedagogy and physical learning spaces. This study also is intended to encourage discussion among stakeholders on the best medical school developments, in light of emerging learning trends relevant to their institutions. The study has revealed that new environments for learning are being designed or reshaped in response to changing pedagogical approaches, to incorporate new information technology, and to accommodate the changing abilities of new generations of learners. Formal teaching spaces for large groups with a 'sage on a stage' are becoming less common than smaller lecture rooms, although classrooms form a large component of universities and will continue to dominate in the future. However, the traditional layout of these spaces is being transformed to incorporate multiple learning modes. Classrooms should be profound places of revelation and discovery. A well-designed space has the ability to elevate discourse, encourage creativity, and promote collaboration. Within the classroom walls, a learning space should be as flexible as possible, not only because different teachers and classes require different configurations, but because in order to fully engage in learning, students need to transition between lectures, group study, presentations, discussions, and individual work time.

The most important technology in the electronic commerce based on Internet is to guarantee the security of trading information exchange. Many technologies are proposed as a standard to support this security problem. One of them is an XML (eXtensible Markup Language). This is used in various applications as the document standard for electronic commerce system. The XML security has become very important topic. In this paper an XML security model for web services based electronic commerce system to guarantee the secure exchange of trading information. To accomplish the security of XML, the differences of XML signature, XML encryption and XML key management scheme respect to the conventional system should be provided. The new architecture is proposed based on unique characteristics of XML. Especially the method to integrate the process management system need to the electronic commerce is proposed.

The ingenuity of structural engineers in the field of tall and super-tall buildings has led to some of the most remarkable inventions. During this evolution of structural engineering concepts in the last 100 years, the technical challenges that engineers encountered were extraordinary and the advances were unprecedented. However, as the accomplishments of structural engineers are progressing, the desire for taller and safer structures is also increasing. The diagrid structural system is part of this evolving process as it develops a new paradigm for tall building design combining engineering efficiency and new architectural expression. The first appearances of this type of tall buildings have already been constructed and the interest of both engineering and architectural communities is growing mainly due to the many advantages compared to other structural systems. This paper presents a simple approach on optimizing member sizes for the diagonals of steel diagrid tall buildings. The optimizing method is based on minimizing the volume of the diagonal elements of a diagrid structure. The constraints are coming from the stiffness-based design, limiting the tip deflection of the building to widely accepted regulative limits. In addition, the current paper attempts to open the discussion on the important topic of optimization and robustness for tall buildings and also studies the future of the diagrid structural system.
This study presents the design and implementation of a web-based remote laboratory for a multi-mode single-leg power converter, which is a topic in advanced power electronics course. The proposed laboratory includes an experimental test rig with a multi-mode single-leg power converter and its driver circuits, a measurement board, a control platform, and a LabVIEW-based user interface program that is operated in the server computer. Given that the proposed web-based remote laboratory is based on client/server architecture, the experimental test rig can be controlled by a client computer with Internet connection and a standard web browser. Although the multi-mode single-leg power converter can work at four different modes (main boost, buck-boost, boost-boost, and battery boost modes), only the buck-boost mode is used in the experiment because of page limit. Users can choose the control structure, control parameters, and reference values, as well as obtain graphical results from the user interface software. Consequently, the feedbacks received from students who conducted remote laboratory studies indicate that the proposed laboratory is a useful tool for both remote and traditional education.

Recently, there are several problems in space, contiguity and facility of the existing harbors issued due to the trend of enlarging the container capacity of the large container vessel, the Mobile Harbor has been proposed conceptually as an effective solution for those problems. This concept is a kind of transfer loader of the containers from the large container ship, which is a floating barge with a catamaran type in the underwater part, and so prompt maneuverability and work effectiveness. For the safe mooring of two floating bodies, a container and the mobile harbor, in the near sea apart from the quay, a robot arm mooring facility specially devised would be designed and verified through comparison study under various environmental sea condition in the inner and outer harbor. DP system (Dynamic Positioning System) using the azimuth thruster and a pneumatic fender, etc, will be considered as a next research topic for the mooring security of multi-body floaters.

The purpose of this study is to explore the issues and implications for landscape design education in Korean landscape architecture by analyzing the National Exhibition of Korean Landscape Architecture(NEKLA). This study analyzed the suggested topics and selected site as well as the commentary that appeared in the NEKLA's award-winning book published from 2004 to 2014. Results of the study are as follows: First, topics of NEKLA are not only competition guidelines but related to exploring new area and role of Korean landscape architecture. Second, most dealing with site is 'industrial heritage and regeneration space' and 'green infrastructure'. In more recent years, a larger variety of sites were addressed. Third, site locations are concentrated in metropolitan areas, and awards and participation of the non-metropolitan universities was very low. Fourth, seven criteria can be applied in a general landscape design competition such as 'newness of the concept(idea)', 'logicality of the design process', 'selection of site fidelity of analysis(interpretation)', 'presentation and completion of the master plan', 'consistency with the theme', 'linkage of concepts and results' and 'feasibility'. The evaluation criteria are increasing the sophistication of the design language to provide useful suggestions on how to find design education methods. Its implications are as follows: First, training is essential to derive innovative ideas, but it should avoid excessive concept-oriented education. Second, design education may include instruction on how to define the problems related with the site. Third, more emphasis on design logic is essential to transform the innovative concept to actual results. Fourth, 'slick images' unrelated to design should be suppressed. Fifth, practice is needed to solve the topics addressed in the design process of education. Sixth, 'feasibility' and 'creative thinking' are necessary to recognize a reciprocal relationship that is helpful to one another. This study uses direct quote commentary to minimize the subjectivity of the researcher and to trace issues of the contemporary landscape architecture more directly and vividly. This study is a record waiting for another review as meta-criticism. In this regard this study, the landscape architect of the next times will have a mean that historical records to review the current thinking of the landscape theory and design.

This research aimed to propose an organizational system that implements a planning agreement in local small and medium sized city, Korea. To conduct this research, three successful cases were deduced using integration systems to investigate purpose and background of the planning agreement. Articles, reports, media, and participation in meetings and workshops related on this topic are used for collecting data and interview of regional activists and experts, and public officials were carried out. Among them, the case of Yeongju city that used the new integration system instead of pre-adminstration system was examined in detail. There are three local governments; Yeongwol-gun, Jeungpyeong-gun, and Yeongju city which have successfully fulfilled projects from various departments of central adminstration not projects of planning agreement. The similarity noticed between those three cases is to continue various projects from several departments of central adminstration for numerous years and contribute to regional revitalization. A successful factor was to establish organizational system and manage it for the integration plan and performance for appropriate regional and administrative characteristics. In particular, in the case of Yeongju city, organization for urban architectural management composed of civilian experts were formed, authorized status on administrative organization was established, and the function and role were identified. It is helpful to other local governments to carry out the projects of planning agreement as the case of Yeongju city is now a new method.
