  • In an oil hydraulic vane pump for an automobile, it is very important that the vane doesn't separate from the camring inner race during the operation of the vane pump. The vane generally has not only the oil hydraulic force acting on the bottom face to contact to camring inner race but there is also an inertial force and viscous force. Because the oil hydraulic force is much larger than the other forces, the contact state between the vane tip and the camring inner race is sufficient. However, the contact state between the vane tip and the camring inner race is only affected by the inertial and viscous forces during the delivery of the vane pump, because the oil hydraulic force acting on the vane is in equilibrium. If the inertial force is larger than the viscous force, which happens when the vane is separated from the camring inner race, the delivery of the vane pump can become unstable or the volume efficiency can become decrease rapidly. Therefore, in this paper, the state of the contact between the vane and the camring is considered. The results show that the rotating speed of the shaft, the operating temperature of the oil, the clearance between the vane and the rotor, and the mass of the vane exert a great influence on the state of the contact between the vane and the camring.

  • In a very competitive construction business environment there is a need to measure and manage business performance across a wider spectrum of business success criteria. The Balanced Scorecard (BSC) and Triple Bottom Line (TBL) reporting concepts are emerging as champions in the race for sustainable business success. The construction business organisations are often judged based on their financial performance as well as wider performance. This paper aims at developing a universally accepted tool for assessing contractors' wider business performance in the construction industry. A prototype of web-based business performance measurement system has been developed to help contractors assess their own performance aimed at uplifting their performance. The consultants/clients can also use the tool to measure contractors' performance in a value-based contractor selection. The system was developed based on the research conducted among 63 senior construction professionals and therefore further research with the participation of a large number of managers across different countries and also an upgrade of the system will be required.

  • 유럽연합에서 회사법 통일의 노력은 리스본조약 이전부터 회사법과 관련한 규칙과 지침을 설정했다는 점에서 중요한 의미를 지닌다. 유럽연합 회사법의 법규범은 자체의 규칙을 통해 유럽주식회사라는 개념을 설정하였으며, 공개유한책임회사인 유럽주식회사와 더불어, 2008년 이후에는 중소기업을 위한 폐쇄유한책임회사에 대한 입법도 추진하고 있다. 최근 유럽주식회사법을 근거로 설립된 회사의 수가 증가되면서 발전된 형태의 회사법에 대한 논의가 활발히 진행되고 있으며, 이는 우리나라 회사법 분야에서도 흥미로운 주제가 된다. 기존의 유럽회사법에 관한 국내연구는 전반적인 유럽회사규칙 및 지침에 대한 내용을 소개하고 있으나, 근래에 이루어지고 있는 회원국 법률간 하향경쟁과 이를 통한 회원국의 입법에서의 변화, 그리고 유럽에서의 회사법연구에 대한 최근 논의에 대해서 다시 다루어 볼 필요가 있다. 따라서 이글에서는 유럽연합조약을 통한 설립의 자유와 이를 통한 각 회원국의 법률 간 경쟁과 유럽주식회사규칙의 제정 배경에 대해서 살펴보고 현재 유럽주식회사규칙의 내용을 평가한다.

  • This paper attempts to assess the impact and implication of globalization on social welfare in Korea. It is no easy task to give an exact definition of globalization and the concept has been used in many different senses, that is, economic, social, cultural, political globalization. In particular, the meaning of globalization is connected to the rise and expansion of neo-liberalism. Globalization tends to undermine national welfare systems by the social dumping, race to the bottom, privatization of social services, labor market flexibility. On the other hand, in many studies the negative impact of globalization on social welfare has been questioned. Instead of end or erosion of the welfare systems, it is emphasized that competitiveness and welfare may go hand in hand. We investigate the question what and how the social welfare system in Korea has been changed in globalization process. In order to answer, this paper examines the changes in welfare ideology, welfare programs, social stratification level after economic crisis. The result of analysis is that in contrast to globalist expectations which is to retrench social welfare, paradoxically, the welfare system in Korea has been reinforced in globalization process. Therefore, the alleged impact of globalization on social welfare will be independent on the structure of domestic institution, political legacies, and on the socialization of global politics such as IMF, World Bank, ILO, UNDP, etc., on the welfare politics of stakeholders in national state.

  • This study aims at providing useful fundamental information to re-establish the theories of modern fashion by examining the origination and genealogy of street style. The street styles focusing on caucasoid have a variety of genealogies such as western type, beat, teddy boy, hippie, skinhead, punk, neuron-mantic, indie kid, riot grrrl, grunge and techno cyber punk. In the same period, on the contrary, the streets styles focusing on negroid are zootie, hipster, modernist, rude boy, two-tone, rastafarian, funky, B-boy, fly girl, raggamuffine, bhangra, and acid jazz, which are seen as the culture of the large cities formed along Atlantic Ocean and Caribbean sea like England, America and Jamaica. These have root as the main fashion in western society. Ironically, most of the subculture concentrated on the whites were racists. Because of such a reason, the street styles have been formed as resistance culture that was unable to sympathize with their society and characteristics by distinguishing the whites and the colored people. Zootie or hipster that is one of the street fashion styles was formed in the 1940-50s, while the colored people who lived in the west Indies migrated to England or America. As a minimal modernist style called Ivy look in US, in that time, anti-culture formed by teenagers in whitey, teddy boy and mods fashion can be strictly different from the zootie and hipster. The colored people's street styles of the 1960s developed into aggressive and hard forms from the rude boy and two-tone while their resistance toward the whites was stronger. The rastafarian style researched the peak as the colored people's traditional ethnic characteristics or resistance intention for their freedom in the 1970s. In that time, The colored people's street styles of the 1960s developed into aggressive and hard forms from the rude boy and two-tone while their resistance toward the whites was stronger. The rastafarian style researched the peak as the colored people's traditional ethnic characteristics or resistance intention for their freedom in the 1970s. In that time, the street styles of the whites were mostly the skinhead or hippie. Most of them were racists toward the colored people. The punk type on shown on the whites focused on luxury and exaggerative costume. On the contrary, the funky style of the colored people focused on aggressive nihilism and form. With B-boy, fly girl, reggae, rap music, and break dancing in the 1980s, the subculture gradually told on the high fashion as well as the culture between the whites and the colored people. From such aspects, the colored people tried to maintain their unique traditional characteristics. However, their individual values surged by the coming young generation excluded the colored people's characteristic street styles. Focusing on gender, violence and private success among their major concerns, the raga muffin style that represents multi-races and multi-cultures was formed. The jazz style in the 1990s showed cold post-modernistic eclecticism different from that of the 1940s-50s. Simultaneously, the various classes appeared their street styles by emphasizing on each personality. Now that we are living in multi-cultural society, a human race or nationalism concept is getting obscurer. There is no obvious boundary line in the differences between human race and its fashion.

  • Globalization has fuelled the desire for simplicity and flexibility in rules and processes within nations. de Soto (2000) calls for the simplification of rules to enable people to join the formal economy. Friedman (2005) echoes the need for simpler rules, to attract business and capital. Market-based approaches to governing have been adopted in many nations due to globalization. Recent developments demonstrate that such approaches fail. Globalization may lead to impoverishment in the absence of proper forms of governance (Cooney 2000). That is why it has the tendency to become a "race to the bottom." Regulatory measures can be costly, and the costs of doing business are uneven across nations. This unevenness is being used as a comparative advantage. Others call this regulatory competition (Smith-Bozek 2007) or competitive governance (Schachtel and Sahmel 2000), which is similar to the model of Charles Tiebout. Collaborative governance is an approach that governments could use in lieu of the competitive method. Mechanisms that enable stakeholders to exchange information, harmonize activities, share resources, and enhance capacities (Himmelman 2002) are needed. Philippine public policy encourages a shift in modes of realizing labor market governance outcomes from command to collaboration (Sale and Bool 2010B; Sale 2011). Is labor market governance and regional development in the Philippines collaborative? Or is the opposite - competitive governance (Tiebout model) - more evident? What is the dominant approach? This preliminary research tackles these questions by looking at recent data on average and minimum wages, wage differentials, trade union density, collective bargaining coverage, small and bigger enterprises, employment, unemployment and underemployment, inflation, poverty incidence, labor productivity, family income, among others, across regions of the country. The issue is studied in the context of legal origins. Cultural explanations are broached.

  • Rat-race 구조의 변형인 Gysel 전력분배기는 분배기내 저항을 쉽게 설정할 수 있는 장점을 가지고 있다. Gysel 전력분배기 내에서 선로 임피던스를 다르게 설정하면 두 개의 출력단자에서의 출력 전력 비율을 다양하게 분배할 수 있다. 본 논문에서는 Gysel 전력분배기에서 선로 임피던스를 변화하여 두 개의 출력 단자의 출력 비율을 1:3 또는 3:1로 선택할 수 있는 회로를 제안하였다. 선로의 임피던스 변화는 마이크로스트립 선로 형태의 전송선로 밑면에 비접지 동판을 위치시켜 구현할 수 있다. 비접지 동판과 접지면이 단락 연결하면 전송 선로는 마이크로스트립 선로로 동작하고, 비접지 동판과 접지면을 연결하지 않으면 전송 선로는 코플라나 선로로 동작하게 된다. 제안된 Gysel 가변전력분배기는 중심주파수 1.5GHz에서 제작하였다. 제작된 Gysel 가변 전력분배기는 1.3~1.7 GHz에서 입력 반사계수(S11) -17dB 이하, 두개의 출력 단자의 전력차는 4.8±0.2dB, 높은 출력 전력을 가지는 단자로의 신호 전달계수(S21)는 -1.39±0.12dB, 낮은 출력 전력을 가지는 단자로의 신호 전달계수(S31)는 -6.15±0.08dB의 안정된 값을 가졌다.
