The Effect of Class and Employment Type on the Awareness of Irregular Work Issues in Korea and ｜apan

Recently, there is greater recognition and increased attempts to protect the rights of irregular workers within Korea and Japan, especially in Korea. This is because of more and more public awareness of the polarization in material conditions between regular workers and irregular workers. So, this study focuses on the main factors explaining awareness of irregular worker issues of each of the classes, and relationship between class consciousness in both countries. The result shows that among factors affecting awareness of irregular work issues, negative effect of subjective employment stability was significant in both countries. In regard of anti-flexibility, while strong class effect was observed in Korea, negative effect of anti-neoliberalism was observed in Japan. This is seemingly contradictory that who opposes neoliberal economic policies agrees with labor market flexibilisation. This phenomenon could be explained by labor market characteristics in Korea and Japan. Japanese labor market is characterized by low flexibility and strong segmentation, while Korean labor market is characterized by high flexibility and strong segmentation. Interaction of these two characteristics increases the labor market inequality in Korea.

Development of the Urban Periphery and Issues Related to Urban Landscape Due to Gated Communities

Due to the industrialisation and rapid urbanisation after 1950＇s, housing demand has increased together with an insufficient housing production to meet the need in Turkey. As a consequence of the large deficit between the annual housing demand and supply, squatter housing construction was the major means for shelter of low income families who can not have their place in the housing market as buyers. Squatter houses are located either on the peripheries of the cities or mostly outside of the urban boundaries on public land or illegally subdivided land by creating many physical, social and environmental problems. After 1990＇s, depending on the globalisation wind and neo-liberal policies that enriched the new elites who have new life styles, the housing capital focused on these group. After 1999 earthquake in Turkey, the fear of possible earthquake has also changed the housing preference as from the high-rise apartment buildings to the lower detached houses. As a consequence of this supply-demand chain, the private housing investment was directed to the gated communities which are isolated settlements with restricted access, so that public spaces are privatised or their use is prohibited or controlled on the edge of the metropoliten cities. These settlements also have physical and social problems. This paper will analyze the change of urban periphery, location and relation with the natural thresholds and the main transportation system of these settlements of Turkey in the light of literature review and some development plans and interview with real estate developers and users.

The United States： Economic Crisis, Productive Restructuring and the New Precarious Labor Conditions

The contemporary economic crisis should be considered within the framework of the contradictions created by the neoliberal model that was adopted in the mid-1970s, in the United States and throughout much of the world. The changes in the labor market and new forms of workforce exploitation based on deregulation, the increase of off-shoring, and flexible hiring practices have led to ＂new＂ precarious labor conditions. Due to the crisis, the United States labor market has been characterized by four factors： the increase of the unemployment, the unedited growth of the informal sector, a dramatic increase in precarious labor conditions for all workers, especially young people, minorities, and immigrants, and the increasing wage polarization. However, capitalist profit rates have actually substantially increased due to neoliberal policies and the resulting economic crisis. This situation led to a rise in the overexploitation of labor. It has had subsequent effects on unemployment, informal work, precarious labor conditions, and unequal salary distribution, especially in recently created positions. Increased labor flexibility has changed the typical forms of wage employment, and stable employment has been replaced by temporary and part-time employment usually with low wages and without social security and benefits.

A Controversial Political View： Rorty＇s Moral Finitism and Religion in the Public Square

Richard Rorty＇s moral finitism is based on some ideas from John Stuart Mill＇s work On Liberty. For Rorty, religious truths would be the main obstacles for the development of freedom and, at the same time, for human happiness. Rorty introduces the concepts of contingency and literary culture to express the situation of personal moral development, stressing that our life must be seen as an endless narration. So, there is no fixed development given once and for all. Rorty＇s anticlericalism is also based on the idea that the creation of clerical institutions and hierarchies is dangerous in the sense that they pose demands which go beyond individual perspectives and make religious obligations be prior to moral ones. Nevertheless, there are some misconceptions in Rorty＇s position when he discusses the idea of moral obligation and the relationship between religion and religious institutions.

Resisting the Violences of ＂Market Normalisation＂： The Importance of Critical Pedagogies for Critical Criminology

The neo-liberal re-positioning of the educational-explorative realm to a vocational market-confinement has already impacted quite heavily on the educational sector in England and Wales and is now being imposed on a European wide scale. However, global as well as European students＇ protests illustrate that resistance to this ideology is gathering pace, and not only involves students and academics but also reaches wider parts of societies. This paper seeks to demonstrate the need for critical pedagogical practices that seek to sensitise students to the modes of current ＂conditions of domination＂. It further suggests critical criminologists to foster and engage in a process of public, intellectual, and intercultural exchange of ideas about education and educational institutions away from merely rationalistic, one-dimensional and profit-orientated ambitions toward a multitude of exchanges about meanings and purposes of such important socio-cultural and political institutions and processes that shape ＂subjectivities＂, inter-subjectivities and thus entire socio-cultural and political spheres. Such processes and active engagements are crucial to the agenda of critical criminologists, and perhaps most importantly, vital to the continued existence of a critical criminology that understands itself as proper ideology critique.

Development and study on automatic balancer based on counter weight by magnetic force

Rotating machines are very sensitive to mass unbalance which has a harmful effect on its running accuracy and service life. Therefore,a variety of dynamic balancing methods and devices are studied to reduce the vibration caused by mass unbalance. On-line active balancing is a new balancing procedure which is more convenient and precise than the previous methods. In this paper,an electromagnetic balancer based on ring coils and permanent magnets is presented. The balancer has a simple structure and the self-locking function without clutch,and transfers power by the non-contact electromagnetic field. In order to justify the rationality of its design,a two-dimension(2D) electromagnetic finite element model is conducted to verify that this magnetic circuit has no flux leakage and saturation. A three-dimension (3D) 1/10 model of the balancer is built to obtain the self-locking torque and driving torque. Based on the research work above,an electromagnetic balancer is developed. By testing the balancer using COCO80,it is verified effective to reduce the rotor unbalance at the speed of 1300 r/min.

Hybrid-augmented intelligence： collaboration and cognition

The long-term goal of artificial intelligence （AI） is to make machines learn and think like human beings. Due to the high levels of uncertainty and vulnerability in human life and the open-ended nature of problems that humans are facing, no matter how intelligent machines are, they are unable to completely replace humans. Therefore, it is necessary to introduce human cognitive capabilities or human-like cognitive models into AI systems to develop a new form of AI, that is, hybrid-augmented intelligence. This form of AI or machine intelligence is a feasible and important developing model. Hybrid-augmented intelligence can be divided into two basic models： one is human-in-the-loop augmented intelligence with human-computer collaboration, and the other is cognitive computing based augmented intelligence, in which a cognitive model is embedded in the machine learning system. This survey describes a basic framework for human-computer collaborative hybrid-augmented intelligence, and the basic elements of hybrid-augmented intelligence based on cognitive computing. These elements include intuitive reasoning, causal models, evolution of memory and knowledge, especially the role and basic principles of intuitive reasoning for complex problem solving, and the cognitive learning framework for visual scene understanding based on memory and reasoning. Several typical applications of hybrid-augmented intelligence in related fields are given.

Quantum Gravitational Contributions to Gauge Field Theories

We revisit quantum gravitational contributions to quantum gauge field theories in the gauge condition independent Vilkovisky-DeWitt formalism based on the background field method.With the advantage of Landau-DeWitt gauge,we explicitly obtain the gauge condition independent result for the quadratically divergent gravitational corrections to gauge couplings.By employing,in a general way,a scheme-independent regularization method that can preserve both gauge invariance and original divergent behavior of integrals,we show that the resulting gauge coupling is power-law running and asymptotically free.The regularization scheme dependence is clarified by comparing with results obtained by other methods.The loop regularization scheme is found to be applicable for a consistent calculation.
