  • Regulation theories has paid little attention to spatial regulation processes, while it has focused on economic and social regulation processes. More specifically, there have been little researches on regulationist approach to the transformation of the post-socialist system in the context of the space economy. Therefore, the article has attempted to conceptualize the transformation of space economy under the post-socialist system in the light of regulation theories. The space economy could be regarded as the foundation of the reproduction of social relations. Thus, the transformation of post-socialist system has led to the fundamental changes in enterprise and industrial networks as well as social relations in spatial contexts. In this perspective, the research has attempted to identify 'the mode of enterprise regulation' regarded as a codified firm networks by investigating intra-, inter- and extra-firm relations associated with the transformation of post-socialist system. Also, it has intended to suggest three types of the space economy - (1) disembedded economies based on the isolated networks and dissolution of pre-existing networks, (2) embedded economies based on the interaction of institutions and restructuring of networks, and (3) over-embedded economies based on the insulated institutions and endurance of pre-existing networks-in accordance with the governance, institution and networks in the post-socialist system.

  • When an off-road tracked vehicle travels, an engine thrust that is transmitted to the continuous track induces a shearing action on the soil-track interface. Consequently, the relative displacement known as slip displacement takes place on the soil-track interface, which develops an associated soil thrust acting as a traction force. For the loose or soft ground conditions, an excessively large slip displacement can be required for the development of the desired soil thrust which will make the tracked vehicle mobile and therefore the outer surface of the continuous track is generally designed to protrude with grousers. This paper fundamentally studied the effect of grousers on the soil thrust of off-road tracked vehicles. Based on the soil-track interaction theory, a new soil thrust assessment method that properly takes into account the effect of grousers was developed. Also, the soil thrust of off-road tracked vehicles equipped with a number of grousers was evaluated using the developed assessment method. The results showed that grousers increased the soil thrust of the continuous track, enhancing the overall tractive performance of off-road tracked vehicles. These effects were more obvious as the height of grouser increased and the spacing of grouser decreased; thus, it is concluded that the grouser which has smaller shape ratio (span of the grouser to a grouser height) significantly enhances off-road tracked vehicle's performance.

  • This paper provides an overview of political ecology, a body of theory that focuses on the links between political and economic inequality on the one hand, and environmental degradation on the other. Adopting a tripartite classification scheme that identifies three political ecology traditions -'classical', 'democratic' and 'poststructuralist'- the discussion shows the need for a move within the poststructuralist tradition away from a narrow and quasi-idealistic focus on discourse to a more robust philosophical engagement with ontological and epistemological issues grounded in Gilles Deleuze's development of Nietzschean materialism. From there. the author draws on numerous examples from Canada, and surveys the available literature on 'bioregionalism', a relatively new intellectual tradition evolved from the North American environmental social movements of the 1970s and 1980s. The so-called 'bioregional approach' stresses that administrative units need to reflect (rather than transect) eco-geographical and cultural features. Bioregionalism is described and assessed as a potential pragmatic research framework for geographers and other planners wishing to respond proactively to the call for a revamped, poststructuralist political ecology. The paper concludes that a bioregional approach to political ecology avoids the weaknesses identified by certain critics, provides scope for consideration of fundamental philosophical ideas, and as such, represents a practical development of a poststructuralist political ecology.

  • It is generally accepted that there is always a potential for crisis in the capitalist society because of the internal contradiction of capitalism. The contradiction is explicitly and implicitly expressed in space. The fundamental contradiction in capitalism, however, is controlled and mediated by the state (i.e., the capitalist state). We thus could argue that the state plays an important role in the capitalist society and in the capitalist spatial formation. It is necessary to note how and why spatial structure has developed unevenly in capitalist societies, particularly in the U.S., The general concept of uneven geographical development is understood in the context of the capitalist economic system and the role of the state. But the problem is that the capitalist state itself has a contradiction between the productive function (i.e., accumulation function) and the reproductive function (i.e., legitimation function). The compromise of the two functions is always the dilemma of the state and the state becomes the object of class struggle (e.g., political class struggle) . The research questions are as follows. First, what is the role of the state in the economic structure and what is the internal problem of the state\ulcorner Second, what is the role of the state in space economy (or in spatial structure)\ulcorner And last, what is the relation between the federal state and the local state in the U.S. and how does the relation form the urban policies and thus the urban and regional development\ulcorner The paper will be looking at how the political economy in the U.S. explains unevenly developed geographical phenomenon.

  • The purpose of this study is to investigate the effects of team - based simulation training in nursing students on critical thinking and communication clarity. This study was conducted from October 2017 to November 2017 for 69 students (33 experimental group and 36 control group) who took a course of "Basic Nursing Theory and Practice" students in a major nursing student in P city, Gyeongbuk province. Collection and analysis. In this study, we conducted a questionnaire survey using a tool of critical accidents measurement by Yoon Jin(2004) and a communication clarity tool by Hye - jin Jo(2013). Statistical analysis was performed using SPSS 23.0, Chi-square, Fisher's exact test, t-test and ANCOVA. Data analysis showed that the groups participating in the SBAR team based simulation training were significantly more effective than the control group in critical thinking (F = 11.91, p <.001) and communication clarity (F = 4.40, p = .040). Based on these results, it is shown that using SBAR team - based simulation learning for nursing students is effective in teaching 'fundamental nursing and practice' and can be recommended as teaching method for nursing students.

  • Two-phase vapor-liquid flows exist in many shell and tube heat exchangers such as condensers, evaporators, and nuclear steam generators. To understand the fluid dynamic forces acting on a structure subjected to a two-phase flow, it is essential to obtain detailed information about the characteristics of a two-phase flow. The characteristics of a two-phase flow and the flow parameters were introduced, and then, an experiment was performed to evaluate the pressure loss in the tube bundles and the fluid-dynamic force acting on the cylinder owing to the pressure distribution. A two-phase flow was pre-mixed at the entrance of the test section, and the experiments were undertaken using a normal triangular array of cylinders subjected to a two-phase cross-flow. The pressure loss along the flow direction in the tube bundles was measured to calculate the two-phase friction multiplier, and the multiplier was compared with the analytical value. Furthermore, the circular distributions of the pressure on the cylinders were measured. Based on the distribution and the fundamental theory of two-phase flow, the effects of the void fraction and mass flux per unit area on the pressure coefficient and the drag coefficient were evaluated. The drag coefficient was calculated by integrating the measured pressure on the tube by a numerical method. It was found that for low mass fluxes, the measured two-phase friction multipliers agree well with the analytical results, and good agreement for the effect of the void fraction on the drag coefficients, as calculated by the measured pressure distributions, is shown qualitatively, as compared to the existing experimental results.

  • This study is the subsequent full-scale research of a TV drama writer who has been out of scholarly pursuits as it explores Su-Hyeon Kim's underlying consciousness with focusing on her heroines, the and . The author Su-Hyeon Kim clearly distinguishes a TV melodrama from a TV home-drama by her own self-control, which is a rare case in TV drama genres, therefore, her consciousness lights up at her melodrama. This study applies Lacanian theory to the author's melodramas for examining the author's under-lying thought. For Lacan the subject is an 'alienated', 'privative', 'fractured' 'being' as an imperfect language, the symbolic order, forms the subject through its signification. The subject desires the other's desire, and wants to become an object for the other's desire. The desire constantly demands an integral world, a perfect love, the wholly harmonious imaginary order. And it lasts up as it refuses the symbolic order's imperfection while it works its unconscious fantasy. Lacan states that only the 'traversing the fantasy', 'separation' would give birth to the real, liberated subject. Despite a 20-years of rift within two works, the and have an identical conflict core, that is a subject's constitutive, fundamental privation and desire of a human being. Su-Hyeon Kim's underlying consciousness complies with her continued theses of an inquiry into the subject's real liberation and freedom when desire of the rings produces the subject's alienation, privation, and the pursuit of a impossible perfect love.

  • The reason why creativity becomes the important subject in 21th century is that it does an important role which solves many problems surrounding our whole life in this internationalization, globalization, knowledge-information age. But scholars who formerly researched the creativity-field explain the necessity of creativity with the internal and fundamental reasons. That is, scholars say that creative activities produce originative products and originality itself. And it is the root of which will be able to discover meaning of life and it -creativity - is successive activities that is demanded when individual life want to obtain important value by expressing one's inner world to the outside using creative resource. Recently, with the trends of present age and the educational needs, research about creativity is actively carried out and it draws out the results that creativity can be developed and enhanced through education and training. So, now many researches have focused on how to develop the creativity. Investigating those researches, we found that the recent issues of researches on creativity were changing and now they focused on creative instruction methods and behavioral factors. Especially, they were selected as the subject related to the creative education - creative instructional method and program, atmosphere in classroom, and factors of teacher. It means that the past researches which were a little bit conceptive have been changing to material ones which will be able to enhance creativity and its effect. So, in this research, we have developed the program for CPS(Creativity Problem Solving) and verified its effect.

  • The educational purpose of a junior college is believed to be to effectively train and produce professional workers equipped with the knowledge and skills required in various technical fields of modern society. Since dental technology takes its share of an important role through the enhancement of people's health and the construction of a whlfare society, the prosthodontia department is imposed with a great responsibility to train highly skilled, responsible dental technicians who will meet the social demands. To attain this goal, those who are in charge of the training and education should place emphasis on the development of better educational programs. In other words, the present curriculum which is lacking in many comprehensive aspects, is not satisfactory to provide the students with the required know-how and qualities. As is known, a currculum is the detailed guidance to the efficient operation of an educational program, and that of dental technology is not an exception. In addition, dental technology requires very detailed programs in training, because it requires both diversified and comprehensive application of serveral different fields. The following are the main points to be taken into consideration in developing an effective curriculum for this department. 1. The curriculum should be gradually expanded so that the fundamental subjects will contain principal theories which can be directly applied to the specified majoring subjects. 2. An effective arrangement of time tables should be provided so that basic practice and experiments can be conducted in direct connection with the leatures on the basic theories. 3. For a creative and up-to-date curriculum to help cope with the problems in achieving the aims of technological development and scientific education, intensive and extensive studies should be done on the curricula developed in the advanced countries. 4. The specific majoring subjects should be rearranged to contain new theories which are beneficial to dental technology. As an institution which is spearheaded for ondustrial-educational cooperation, the Junior collegeis role demands that the department should make every possible effect to cultivate highly-skilled technicisns. The following suggestions are made to help work out an ideal curriculum. 1. The basic theory subjects should be selected with consideration toward closely related majoring subjects. 2. The curriculum should be efficiently operated to effectively relate theories with experiments. 3. Subject importance must be rearranged ; It has been found that the ideal proportion of cultural, elective and required subjects is 20%, 20% and 60% respectively. 4. The credit allotments should be reconsidered: The total credits required for completion should preferably be 80; 16 for the cultural and the elective subjects respectively and 48 for the required subject. 5. A Commissioned education system should be formalized for strengthening industrial educational cooperation. 6. Experiments and practice should be intensified with the support of improved laboratory facilities. 7. The training period should be expanded form the present two years to three of four years, in order to produce more highly qualified technicians.

  • The 2011 debris flow in Mt. Umyeonsan in Seoul, South Korea caused significant damages to the surrounding urban area, unlike other similar incidents reported to have occurred in the past in the country's mountainous regions. Accordingly, landslides and debris flows cause damage in various surroundings, regardless of mountainous area and urban area, at a great speed and with enormous impact. Hence, many researchers attempted to forecast the extent of impact of debris flows to help minimize the damage. The most fundamental part in forecasting the impact extent of debris flow is to understand the debris flow behavior and sedimentation mechanism in complex three-dimensional topography. To understand sedimentation mechanism, in particular, it is necessary to calculate the amount of energy and erosion according to debris flow behavior. The previously developed debris flow models, however, are limited in their ability to calculate the erosion amount of debris flow. This study calculated the extent of damage caused by a massive debris flow that occurred in 2011 in Seoul's urban area adjacent to Mt. Umyeonsan by using DEM, created from aerial photography and airborne LiDAR data, for both before and after the damage; and developed and compared a debris flow behavioral analysis model that can assess the amount of erosion based on energy theory. In addition, simulations using the existing debris flow model (RWM, Debris 2D) and a comprehensive comparison of debris flow-stricken areas were performed in the same study area.
