University environment on campus has been changed faster than before in today. Especially, they have devised middle & long-term development plans such as improving the image of campus and increasing campus competitive power to overcome difficulties in campus management. Therefore, many of those have made every effort to provide convenient university services for campus students and to improve the image of campus through building a Ubiquitous-Campus. But existing systems of a Ubiquitous-Campus have not understood actual conditions of IT (Information Technology) for campus students or not provided basic environment to analyze actual conditions of efficient using the system, expectations of the following people about a Ubiquitous-Campus is getting higher md higher though. Must become technology base ubiquitous campus construction, and is real erudition that ubiquitous campus model who can utilize substantially through service construction that is required newly with student's IT infra practical use analysis hereupon such as is required to solve these problems, But there is a limitation on designing the model in rapidly changed university environment on campus. In this paper, we studied about a Students Centralized Ubiquitous Campus model through U-Learning, U-Recruit, U-Printer, and personal information history service which are based on data warehouse for students analysis which is a key point element of building a Ubiquitous Campus.

Most spatial data acquisition systems employing a set of frame cameras may have suffered from their small fields of view and poor base-distance ratio. These limitations can be significantly reduced by employing an omni-directional camera that is capable of acquiring images in every direction. Bundle Block Adjustment (BBA) is one of the existing georeferencing methods to determine the exterior orientation parameters of two or more images. In this study, by extending the concept of the traditional BBA method, we attempt to develop a mathematical model of BBA for omni-directional images. The proposed mathematical model includes three main parts; observation equations based on the collinearity equations newly derived for omni-directional images, stochastic constraints imposed from GPS/INS data and GCPs. We also report the experimental results from the application of our proposed BBA to the real data obtained mainly in urban areas. With the different combinations of the constraints, we applied four different types of mathematical models. With the type where only GCPs are used as the constraints, the proposed BBA can provide the most accurate results, ${\pm}5cm$ of RMSE in the estimated ground point coordinates. In future, we plan to perform more sophisticated lens calibration for the omni-directional camera to improve the georeferencing accuracy of omni-directional images. These georeferenced omni-directional images can be effectively utilized for city modelling, particularly autonomous texture mapping for realistic street view.

In his Phenomenology of Perception, Merleau-Ponty raises a question of why he has to ask what phenomenology is again. This study assumes that the question can be answered in a new understanding of the "nature" concept and finds its possible grounds in the nature concepts of Schelling and Merleau-Ponty. Schelling and Merleau-Ponty develop philosophical thinking from a critical point of view on the Cartesian and Kantian philosophies "Thing-in-itself" by Kant is, in particular, one of important questions that has to be answered in the philosophy of Schelling since Kant further solidifies a dualistic world by leaving thing-in-itself. Schelling solves the question with the concept of identity and Merleau-Ponty solves the question with body-subject. What we notice in this article is the understanding of Shelling and Merleau-Ponty about nature. Schelling believes there are the creative activities of unconscious intelligence in nature, but spirit or intelligence in his nature concept cannot induce an existential being. Here we see that Schelling is still beyond the traditional epistemological framework. To restore the original nature of nature, we must begin with an understanding of the totality of nature. Nature must also be explained through relationships with humans. Merleau-Ponty shows the entanglement of nature and spirit through the body-subject. In Merleau-Ponty's phenomenology, the body is the equivalent of nature. Understanding the forces of nature that Schelling and Merleau-Ponty are trying to show, and at the same time explaining the problem of how the mind or human beings emerge from nature, we will be able to discover the true nature of nature.

There is the commonness between I-Ching of Asian scriptures and Analytic Psychology of C. G. Jung as the conjunction of opposites of yin and yang. I-Ching has the base of the Great Absolute(太極) as yin and yang. Jung's psychology has the basic structure of opposite contents of psyche. The former wants to find the proper answer for the situation as fortune book, the latter realization of personal psyche. At this basis to approach I-Ching through the Analytic Psychology can be connected with the screening its inner system and structure in the frame of depth psychology. Basically I-Ching is the scripture about the good or ill luck, regret and stinginess. All of them are related with the psychology of human beings practically. I-Ching as the main scripture of Asia has the core theme concept of the mean (中). Previously mentioned the good or ill luck, regret and stinginess are included into this as the large view point. The best decision between the given situation and the fortune teller pursues the mean(中) path of both. Jung's psychology also attaches importance to the proper balance among personal conscious, unconscious and his surrounded situations. Goodness is relied on the mean, healthy psyche the harmony with the psychological and real situations of a person. But this balance and mean cannot be achieved without any reason but by the result of the conjunction of opposites. The opposites are the Ch'ien(乾, the Creative, Heaven) and K'un(坤, the Receptive, Earth) as yin and yang in I-Ching and the conscious and unconscious in Jung's psychology. These can be opened to masculine and feminine, psyche and matter, transcendent and existence and casuality and acausal synchronicity. Conjunction of these opposites can develope and create the new conscious and creative situation. Finally yin and yang from the Great Absolute and conscious and unconscious from Self become the opposites and go through necessary step of separation and sublimation for the creation of new level. In the Great Absolute there are yin and yang and yin the latter contains the cyclic process which can make the former renew. Conjunction of opposite in Jung's psychology also go through the similar process as the Great Absolute of yin and yang.

The Ulsan anchorage has not secured a sufficient area than the anchorage demand, and the criteria for objective evaluation are not clearly defined. In this study, a general formula to solve the problems of the current anchorage density and occupancy concept was derived, and new adequacy evaluation criteria were proposed. The proposed criteria were applied to the Ulsan E anchorage to evaluate the suitability of the anchorage. The anchorage density and occupancy of the E1 anchorage were 129 % and 122 %, respectively, showing that both evaluation techniques exceeded 100 %, requiring anchorage expansion according to the evaluation criteria. A plan to expand the anchorage was reviewed considering the traffic pattern and the distance from the pilot boarding point. Therefore, a plan to open 35˚ on a sector at the end of the Ulsan No. 1 fairway was developed, and its suitability was verified. Base on the verification results, there was a part of the overlap between the extended area and the traffic track on the south of the E3 anchorage, but the possibility of affecting the marine traffic was minimal. In addition, it was confirmed that anchorage adequacy was achieved.

This study has done to search for a solution to remove risk limitedly caused by separating weapon system acquisition from operation and maintenance at the view point of Logistic Commander who's responsible for stable operation and maintenance after acquiring weapon system. At the System development stage, unverified overhaul development plan may cause additional manpower and costs after the development, and furthermore it is likely to have risk to lower reliability of the military. Thus, research and development agency should write overhaul development plan at the System development stage, and it should be verified through evaluation and verification test. Secondly, during research and development, institutional supplementation is needed to calculate human and material resources writing overhaul development plan. Thirdly, it should be able to analyze proper operation & maintenance plan and cost for overhaul plan at the pre-investigation stage. Fourthly, the base which can develop overhaul concept and overhaul factors should be included in the need and need determination document. Lastly, for the weapon system which has small amount of high power figure, project management should be performed to be able to specify at the each acquisition level of weapon system to realize Article 28, clause 3 and 4 of Defense business law.

Cultural Studies built on the critical mind of New Left exposes the relationship between culture and power, and investigates how this relationship develops the cultural convention. It has achieved the new perspective that could make us to think culture and art in terms of political correctness. However, the critical voices against the theoretical premises of Cultural Studies have been increased as its heyday in 1980s was nearly over. For instance, Terry Eagleton, a former Marxist literary critic, declared in 2003 that the golden age of cultural theory is long past. This essay, therefore, intends to show the weak foundations on which the approaches of cultural studies to theatre rest and to clarify the general problem of their introduction to theatre studies. The approach of cultural studies to theatre takes the form of 'top-down inquiry' as it applies a theory to a particular play or historical period. In other word, from the theory the writer moves to the particular case. The result is not an inquiry but rather a demonstration. This circularity can destroy the point of serious intellectual investigation as the theory dictates answers. The goal-oriented narrow viewpoint as a logical consequence of 'top-down inquiry' makes the researcher to favor the plays or the parts of a play that are proper to test a theory. As a result it loses the fair judgment on the artistic value of a play, and brings about the misinterpretation. The interpreter-oriented reading is the other defect of cultural studies as it disregards the inherent meaning of the text, distorting a play. The approach of cultural studies also consists of a conventionality as it arrives at a stereotyped interpretation by using certain conventions of reasoning and rhetoric. The cultural theories are fundamentally the 'outside theories' that seek to explain not theatre but the very broad features of society and politics. Consequently their application to theatre risks the destructive criticism, disregarding the inherent experience of theatre. Most of, if not all, cultural theories, furthermore, are proven to be lack of empirical basis. The alternative method to them is a 'cognitive science' that proves scientifically our mind being influenced by bodily experience. The application of cultural materialism to Shakespeare's is one of the cases that reveal the limits of cultural studies. Jonathan Dollimore and Water Cohen provide a kind of 'canonical study' in this application that is imitated by the succeeding researchers. As a result the interpretation of has been flooded with repetitive critical remarks, revealing the problem of 'top-down inquiry' and conventional reasoning. Cultural Studies is antipodal to theatre in some respect. It is interested chiefly in the social and political reality while theatre aims to create the fiction world. The theatre studies, therefore, may have to risk the danger of destroying its own base when it adopts cultural studies uncritically. The different stance between theatre and cultural theories also occurs from the opposition of humanism vs. antihumanism. We have to introduce cultural theories selectively and properly not to destroy the inherent experience and domain of theatre.

Though the wet bottom ash has been used as a type of lightweight aggregate, dry bottom ash, new type bottom ash from coal combustion power plant, has scarcely researched. It is excellent lightweight aggregate in the view point of construction material. This study is performed to check the applicability of dry bottom ash as a fine aggregate in lightweight aggregate concrete, by analyzing various properties of fresh and hardened concrete. We get results that the slump of concrete is within the target range at less than 75% replacement rate of dry bottom ash, the air content is not affected by the replacement rate of dry bottom ash, the bleeding capacity is less than $0.025cm^3/cm^2$ at 75% under of the replacement rate of dry bottom ash, and the compressive strength of concrete show 90% or more comparing the base mix while initial strength development is a little low. Oven dry unit weight of concrete is reduced by 8.9% when replaced 100% dry bottom ash, and dry shrinkage tends to decrease depending on increase of replacement rate of dry bottom ash. Modulus of elasticity of concrete shows no decease at 50% over of the replacement rate of dry bottom ash, while modulus of elasticity of concrete decreases when the replacement rate increases further. The dry bottom ash, when used as a fine aggregate in lightweight concrete, can be used effectively without any deterioration in quality.

To ensure that Korea continues to grow, past governments have been consistent in following a policy of advancing into Russia, Mongolia, and Eurasia. The northern economy can expect to achieve synergistic growth because its economic structure complements that of Korea, which has high energy demand and industrial development. There is also an opportunity to accelerate the growth of the China-Russia-Mongolia economic corridor, which is based on Russia's Look East Policy, China's One Belt One Road, and the Mongolian Steppe Road initiative. The Korean government is pursuing a New Northern Policy to achieve the goal of economic cooperation and peace building with other nations, including North Korea; this policy succeeds the Northern Policy pursued by the previous government. As international economic cooperation requires transportation infrastructure, the demand for shipping, which offers more advantages than road and rail transportation, will increase; thus, it is necessary to prepare for it. Korea's port cities, which have a port that serves as the nodal point for maritime transportation, need to prepare for the New Northern Policy. In this paper, the long-term development of Seosan-Daesan port in the was planned and the North Korea's opening-op plan was considered in accordance with the New Northern Policy. Because international cooperation between the government and the provincial cities is required, cooperation with the Port Authority is needed, along with the proactive attitude of Seosan City, Chungcheongnam-do. The Seosan-Daesan port, which is the center of the liquid energy cargo center, can become the base of the New Northern Policy Region; further, the port can be an opportunity to establish its position as a peaceful economic hub on the west coast of Korea.

PMO(Project Management Office) has been considered as a general approach for the successful operation of IT project. The previous studies tended to emphasize on the roles and functions of PMO in a normative way. However, in practice, since PMO is operated as a joint structure in which client firms and professional PMOs work together, it seems to be important that the implementation system of PMO should be properly formed. In this paper, it is examined whether the competence of client firms and professional PMO influence on the setup of implementation system of PMO, and also whether implementation system of PMO influence of the performance of IT project. In addition, it is also analyzed if the competence of client firms and professional PMO influence differently on the setup of implementation system of PMO, according to the degree of knowledge complementarity. As a result of this study, it is found that the competence of client firms and professional PMO influence positively on the setup of implementation system of PMO, and governance factors such as clear definition of organizational roles, responsibility, and setup of standardized processes are also important in performance of IT project. It is also shown that, if knowledge complementarity is formed with a common knowledge base between client firms and professional PMOs, Project Management Office functions effectively. In summary, for the successful performance of IT project, it seems that it is required to approach from the view point of governance in forming the implementation system of PMO and it is also important to form knowledge complementarity between client firms and professional PMOs.
