Studies on innovation point towards the need for both in-house research and development (R&D) capabilities along with collaborations with external organisations or linkages with other firms, universities and research institutes. The argument is that innovation is not just a firm specific factor but requires support from several other factors which in turn involves developing linkages with various actors/institutions as sources of resources and/or knowledge for innovation. This paper presents findings from an exploratory study about the Malaysian biofuel sector as an innovation system. Instead of using the neo-classical approach and proposing policy interventions based on traditional market failure rationale (Bergek et al., 2008a), the functional analysis of the technological innovation systems (TIS) approach is used to analyse the biofuel sector in Malaysia to help reveal the strengths and weaknesses in terms of its fulfillment of seven critical functions which are necessary for the generation and commercialization of a product. In addition an attempt is made to reveal the inducement and blocking mechanisms affecting the Malaysian biofuel TIS and the seeking of improved poor functionality. These functional aspects of the Malaysian biofuel sector are analysed in different phases of its development to gain an understanding of the different institutions and their functions at different phases of the development of the innovation system.

This paper examines the trends of recently developed human-care robots and social interaction technologies. As one of the solutions to the problems of an aging society, human-care robots have gained considerable attention from the public and the market. However, commercialized human-care robots do not meet user expectations for the role as companions. Current robot services based on short-term interaction and fragmentary pieces of intelligence have encountered difficulty in eliciting natural communication with humans. This results in the failure of human-robot social bonding. Social interaction is being actively investigated as a technique for improving robots' natural communication skills. Robots can form a natural bond with humans through social interaction, which consequently increases their effectiveness. In this paper, we introduce recent human-care robot-related issues and subsequently describe technical challenges and implications for the success of human-care robots. In addition, we review recent trends on social interaction technologies and the datasets required.

The performance test is conducted for the purpose of determining the accurate thermal performance of the power generation facility or deriving the factors of thermal efficiency degradation. Compared to the acquisition method of power plant thermal performance test data by compensating cable or transmission cable, performance test using wireless instrument can acquire digital data in order to shorten the period due to installation and demolition of instrument and enhance safety of workers and relatively accurate data can be acquired thereby improving work efficiency. Wireless instruments have already been introduced to the market a long time ago, and some of them are used in industry such as petrochemical industry. However, there is no example which has been conducted for performance test of power generation facilities. In order to apply power generation facilities, a reliable system capable of acquiring performance data smoothly without affecting the control system is required. The wireless measurement system can eliminate the measurement defects and errors such as the damage due to the movement of the connecting cable, the extension due to the extension of the shield wire, the contact failure at the contact point between the measuring sensor and the connecting wire, This method has the advantage of collecting relatively accurate performance test data.

The market of performance arts industry such as concert, musical and opera etc is now expanding in Korea. However, the inadequate safety management in theatres often causes some accidents. The guarantee of safety in theatres is very important since the accidents in theaters can lead to many casualties and serious property damages. In particular, the small theatres which have no obligation of safety inspection by law are very vulnerable to safety mattes. This study has done the research into the improvement of safety in small theaters through the inspection and analysis of their safety status. For the purpose, this study has inspected and analyzed the safety status of small theaters over 120 in the field of theater management and operation, fire protection, electrical facilities, ceiling structure and etc. Moreover, this study had investigated the law and technical standards related to theatre safety. This study shows that the essentials to make sure of the safety in small theaters are (1) the education to improve the sense of security of people who work in theaters (2) the training to strengthen the operating skills of the facilities in theaters (3) the cooperation and support of the related organization such as technical research center, central and local government.

Presence of water in the lubricating oils could be one of the first indicators of potentially expensive and possibly catastrophic failure of the machine as it may cause displace the oil films to prevent the lubrication function of the oil or chemically react with many oil additives resulting in the oil degradation. In order to detect water content quantitatively in lubricating oils many methods and sensors has been developed. Among these, capacitive sensors including sensitive layer, whose dielectric factor changes according to the water content absorbed in the layer, are proposed mainly in the market. But these sensors are not sensitive to a high water content. Besides, the absorbing layer soils in time. In this work, an evaporation of water moisture from oil into air volume above lubricant surface and condensation of water vapor at a cooling surface was used to measure water content quantitatively in an lubricating oil. Laboratory test results of a prototype sensor were presented. Test results showed that the proposed method could be avaliable to measure a low levels of oil moisture.

The uncooled microbolometer thermal sensor for low cost and mass volume was designed to target the new infrared market that includes smart device, automotive, energy management, and so on. The microbolometer sensor features 80x60 pixels low-resolution format and enables the use of wafer-level vacuum packaging (WLVP) technology. Read-out IC (ROIC) implements infrared signal detection and offset correction for fixed pattern noise (FPN) using an internal digital to analog convertor (DAC) value control function. A reliable WLVP thermal sensor was obtained with the design of lid wafer, the formation of Au80%wtSn20% eutectic solder, outgassing control and wafer to wafer bonding condition. The measurement of thermal conductance enables us to inspect the internal atmosphere condition of WLVP microbolometer sensor. The difference between the measurement value and design one is $3.6{\times}10-9$ [W/K] which indicates that thermal loss is mainly on account of floating legs. The mean time to failure (MTTF) of a WLVP thermal sensor is estimated to be about 10.2 years with a confidence level of 95 %. Reliability tests such as high temperature/low temperature, bump, vibration, etc. were also conducted. Devices were found to work properly after accelerated stress tests. A thermal camera with visible camera was developed. The thermal camera is available for non-contact temperature measurement providing an image that merged the thermal image and the visible image.

본 연구는 심미적 영향요소 중 전형성과 동시에 중요하게 인지되는 또 다른 속성 즉 비례(proportion)를 중심으로 소비자가 선호할 수 있는 디자인을 창출할 수 있도록 하기 위하여 제품의 범주화와 제품 형태분석을 통해 제품에 대한 이상적 비례를 도출해 냄으로써 비례의 조작만으로도 소비자가 선호할 수 있는 차별화 된 제품디자인을 위한 방법론을 구축하고자 한다. 이에 본 연구의 연구방법으로는 시중에 판매되는 제품들 중 비례가 중요하다고 인식되는 제품을 가지고 전형적 모델을 찾아 치수를 유추시켜 2차 자극물을 만들었다. (즉 전형적 모델에서 일정한 치수 변화를 주어 2차 자극물을 만들었다.) 이후 2차 자극물을 동질성분석을 통해 대표적인 2차 자극물들로 실험을 하여 그 제품에서 가장 이상적인 비례를 찾았다. 이후 황금 비례와 이상적 비례와의 관계를 살펴보고 제품들마다 이상적 비례는 따로 있음을 증명하였다. 즉 결론은 "신제품 개발시 비례는 주어지는 규격이 아니라 찾아내어야 할 선호 요소 중 하나이다"라는 것이다.

Considerable controversy exists about the trend of animal traction effects on crop production in dryland farming systems in sub-Saharan Africa (SSA). This problem arises on account of the failure of the few available empirical studies to recognise the important of technological experience of the individual adopting farmers. This study hence addresses this issue by examining the effects of experience in animal traction technology (ATT) on farm size, cropping emphasis, total crop output and farm productivity. It is based on farm management survey data on 42 small holder farm households fro Ghana. Thirty of these households used animal traction technology (ATT) fro crop cultivation and the rest, mainly hand-hoe. The animal traction sub-sample is classified into three groups according to farmers' years of experience with the technology , thus , those with 1-2, 3-10, and more than 10. Evidence from the study shows that the progression of years of experience with ATT leads to inten ification of labour and land use systems, enhancement of degree of motivation to enter into the market economy, increases in total crop output and farm productivity resulting for decreases in cultivated acreages. The implication of the findings is that institutioal and technical support that do accompany the introduction of such technologies should be structured to last for a relatively longer period to accomodate the learning process.

The urban modernity that became an irresistible model for elites in Asia in the decades before and after 1900 was far from being gender-neutral. It represented an exceptional peak of patriarchy in its exclusion of respectable middle class women from the work force, from ownership and control of property and from politics. Marriage was indissoluble and the wife's role in the male-headed nuclear family was to care for and educate the abundant children she produced. Puritan religious values underlined the perils for women of falling outside this pattern of dependence on the male. Though upheld as modern and civilized, this ideal was in particularly striking contrast with the pre-colonial Southeast Asian pattern of economic autonomy and balance between women and men, and the relative ease of female-initiated divorce. Although attractive to many western-educated Southeast Asian men, including religious reformers determined to 'save' and domesticate women, urban respectability of this type was a poor fit for women accustomed to dominant roles in commerce and marketing, and at least equal ones in production. Southeast Asian relative failure in the high colonial era to adapt to the modern market economy may also have a gendered explanation. We should not be surprised that patriarchy and puritanism became more important in Southeast Asia as it urbanized in the late 20th Century, since this was echoing the European experience a century earlier. The question remains how far Southeast Asia could retain its relatively balanced gender pattern in face of its eventual rapid urbanization and commercial development.

This paper attempts to assess the Basel Committee's bank supervisory standards and capital adequacy rules, and thereby rethink whether global convergence in banking regulation is desirable. To that end, it seeks to address the impetus for the creation of the Basel Committee, and explore driving forces behind the internationalization of bank regulatory and supervisory standards. Following the historical and theoretical analysis of the internationalization of bank regulatory standards, the movement toward global standards in banking is reviewed. More importantly, this paper seeks to explore the origins of the Basel Accord on bank capital adequacy. To do so, it largely relies on current theories on the process of negotiating the capital adequacy standards in the areas of political science and international political economy. At this point, this study takes a position as a break against the force of international market failure logic that has enjoyed an exceptionally positive reception among economists, political scientists, and legal experts. Nonetheless, it does not intend to freeze the international coordination and cooperation of banking regulation. Given the understanding of the politics behind the creation of the Basel Accord, this paper evaluates the Basel Accord of 1988 and the new capital adequacy framework(Basel II), and then moves beyond the assessment of the capital adequacy standards In doing so, this study draws lessons from Basel in search of a just world order in the global finance.
