  • The proliferation of technology has made global conduction of business increasingly dependent upon the availability of reliable power. As a result, alternate power systems are being installed and expanded to protect the broadening scope of critical electrical loads. Bus transfer restores designated critical loads to an alternate source when utility derived service becomes inadequate or goes out of service due to any contingency. This paper describes the practices, requirements and implementation of bus transfer of motor loads to an alternate source of power. A new high-speed automatic bus transfer scheme is proposed which includes the development of a new algorithm for determining the type of bus transfer required and the realization of the scheme by using modem protection devices and intra-substation communication facilities.

  • Governments around the world place great hopes in innovation in their search for new sources of growth and for responses to grand challenges, such as climate change, new or re-emerging infectious diseases, accelerating urbanisation, ageing, food security, and availability of clean water. However they must devise their relevant support policies -- including through sponsored research within public research institutes -- taking into account that innovation processes are currently undergoing a major transformation. New innovation patterns include a broadening scope of relevant activities, a growing importance but changing nature of scientific roots of technological development, a stronger demand-pull, the emergence of new local and national STI powerhouses, and the rise of more open and globalised innovation networks. They translate into new opportunities but also constraints for policies to enhance the contribution of public research institutes to national innovation performance. The article derives the main policy implications regarding the desirable evolution of the mission, research focus, as well as the funding and steering of public research institutes, with a special reference to Korea.

  • Sustainability is an important topic within a variety of design areas, including fashion. The 'fast fashion' behavior of consumers is one of the big challenges that sustainable living faces. For the fashion industry, sustainability can be seen as a regulating ethos for higher quality and longer-lasting products, which I argue as embodying an intersection between sustainability and luxury. This study establishes a conceptual model for 'sustainable luxury' that can be implemented as a guide in the fashion design industry and education field. This paper will focus particularly on craft-based fashion within the industry. Through conceptual analysis and case studies, I analyze sustainable luxury through the scope of Soper's (2007) 'alternative hedonism', linking hedonic and selfidentity values as a foundation for the acceptance of and continued drive toward more sustainable luxury products. Unlike other studies which only emphasize the ecological and environmental aspects of sustainability, viz. green/eco design, this study explores sustainability as balanced with its four dimensions: environmental, economic, social, and cultural. Case studies will exemplify this redefined notion of sustainable luxury.

  • With regard to a marine safety system, large vessels are generally loaded with INS (Integrated Navigation System). But although small and medium-sized ships are exposed to safety accidents in the sea, they are not carrying proper navigation devices and equipment. Accordingly, in order to develop INS for small and medium-sized ships(s-INS), an existing INS has newly been organized and integrated. Recently, more strict enforcement of INS-related regulations is expected at home and abroad, and the scope of their applications is being broadened. To keep up with this global trend that ships are being loaded with digital devices and equipment, this study has tried to develop s-INS, broadening its applications, and suggesting a future research plan.

  • This study investigates the determinants of the likelihood of a tax re-audit in Korea. It adopts a researcher-administered questionnaire survey method for data collection. The survey questionnaire is randomly distributed to 1,120 individuals with tax-related knowledge and experience. Using a final sample of 342 responses, we conduct a cross-sectional regression analysis to test our hypotheses. The results show that the level of tax non-compliance significantly affects the likelihood of a tax re-audit. This finding suggests that the increase in re-audits in Korea is attributable to the tendency of the tax authority to conduct a re-audit to detect taxpayers' non-compliance behavior by excessively broadening the scope of re-audits. This study also finds that the level of tax non-compliance is influenced by the perception of procedural unfairness, measured by operational inconsistency and regulatory lack of clarity. Lastly, the results reveal that the level of tax non-compliance mediates the relationship between the perception of procedural unfairness and likelihood of a tax re-audit. This finding indicates that enhancing procedural fairness could fundamentally reduce unnecessary re-audits that infringe on the rights of taxpayers, as the likelihood of a tax re-audit is not solely determined by the level of tax non-compliance but also by perceived procedural fairness.

  • ACE-Asia (Asian Pacific Regional Aerosol Characterization Experiment) in spring 2001 was a turning point to trigger international research interest on Asian dust (AD). This basically arose from the lack of research on AD, the important natural phenomenon to characterize the Northeast Asia. In contrast, health risk related to AD has been the primary concern in Korea. Although due in part to severe AD events of 2001~2002, research and mitigation measures on AD in Korea are typically based on the assumption that AD events are increasing in frequency and severity. However, contrary to the trend in Korea, the number of AD days and emission amounts of AD in China have decreased since 1980s. This paper reviews the impacts of AD on ambient air quality and variations in toxic substances during the AD event, reflecting the concern in Korea. While a great amount of dust particles flow into Korea during the AD event, a considerable amount of dust particles are locally generated as well. Since dust particles are mixed with toxic substances as they pass over polluted areas, the levels of toxic substances become lower in dust particles that do not pass over polluted areas. Broadening the research scope on AD is warranted to understand the AD as an important natural phenomenon, irrespective of its associated health risk.

  • 디지털 캐릭터 리깅은 애니메이션의 생동감을 높이는 중요한 기술이며, 다양하고 복잡한 방식의 리깅 시스템이 많다. 이에 자연스러운 움직임을 위한 모션 테스트를 물고기로 진행한다. 왜냐하면, 2족, 4족 캐릭터의 자료들은 더러 있으나, 물고기(0족) 움직임에 관한 연구의 자료는 많이 없다. 물고기 움직임 제작의 다양성과 복잡성이 증가하면서 비효율적인 시간과 자본도 요구된다. 물고기 특성에 맞는 골조 시스템을 어떻게 만들 것인지는, 어떻게 효율적이고 민첩한 리깅 프로세스를 만드느냐에 달려있다. 본 연구는 높은 시간비용의 리깅 기술 문제를 해결할 수 있는 어드밴스드 스켈레톤(Advanced Skeleton) 기반의 애니메이션 리깅 제작 프로세스와 Maya Rig를 비교하여, 어드밴스드 스켈레톤(Advanced Skeleton)의 장점을 활용해 최적의 자동 리깅 툴을 모색하고, 물고기 애니메이션 연구 범주를 넓힐 것에 목적을 두고 있다.

  • The scope of this work is to determine and compare the effect of electron temperature ($T_e$) and number density ($N_e$) on the yield rate and concentration of reactive chemical species ($^{\bullet}OH$, $H_2O_2$ and $O_3$) in an argon, air and oxygen injected negative DC (0-4 kV) capillary discharge with water flow(0.1 L/min). The discharge was created between tungsten pin-to pin electrodes (${\Phi}=0.5mm$) separated by a variable distance (1-2 mm) in a quartz capillary tube (2 mm inner diameter, 4 mm outer diameter), with various gas injection rates (100-800 sccm). Optical emission spectroscopy (OES) of the hydrogen Balmer lines was carried out to investigate the line shapes and intensities as functions of the discharge parameters such as the type of gas, gas injection rate and inter electrode gap distances. The intensity ratio method was used to calculate $T_e$ and Stark broadening of Balmer ${\beta}$ lines was adopted to determine $N_e$. The effects of $T_e$ and $N_e$ on the reactive chemical species formation were evaluated and presented. The enhancement in yield rate of reactive chemical species was revealed at the higher electron temperature, higher gas injection rates, higher discharge power and larger inter-electrode gap. The discharge with oxygen injection was the most effective one for increasing the reactive chemical species concentration. The formation of reactive chemical species was shown more directly related to $T_e$ than $N_e$ in a flowing water gas injected negative DC capillary discharge.
