This paper presents a user study on an implemented Internet-based teleoperation robot named TeleBot. The objectives of the study were to: a) test the usability of TeleBot, b) compare two commonly used devices to control TeleBot, and c) understand further development and requirement of TeleBot by examining how operators use TeleBot to complete a specific task. A task-oriented user study that included navigating TeleBot to a specific location and use TeleBot’s arm to touch a “X” marking placed on the door, was designed. Eight participants performed the same task using two different types of device. Both objective and subjective data were collected during the study. The results indicated that a) TeleBot demonstrated a certain level of usability; b) showed that the gamepad was slightly easier to use for teleoperation and finally c) deduced further developmental area for TeleBot.

Globalization and the Anti-Globalization Lobby: A Deficit of Thoughtfulness and Clairvoyance

Dilip K. Das 연세대학교 동서문제연구원 2005 Global economic review Vol.34 No.1

As the current wave of globalization strengthened, so did the fury of the anti–globalization lobby against it. The author believes that the members of this lobby failed take a thoughtful and balanced perspective of the on-going integration of the global economy. Indubitably globalization has its winners and losers. In this well-conceived article author establishes that if the members of this group take a good look at the two sides of the coin in an objective and unprejudiced manner, they are sure to see the folly of their ways. A great deal of evidence is available to show that on balance, globalization has had enormous beneficial effect and has improved the plight of the poor in the global economy.

Idiosyncratic Features of the Contemporary Regional Economic Architecture in Asia

Dilip K. Das 대외경제정책연구원 2012 East Asian Economic Review Vol.16 No.2

The objective of this article is to examine the characteristic features of contemporary policy-led regionalism in Asia. It identifies the positive and negative features associated with the free trade agreements that have proliferated in Asia during the first decade of the 21st century. There has been a marked transformation in Asia’s regional architecture in a short span of a decade-and-a-half. The mode and conduct of multilateral trade has been significantly transformed during recent years and Asia could not possibly remain immune to this transformation. The importance of regionalism in multilateral trade has increased steadily. In addition, the tradeinvestment-services nexus has developed and grown increasingly important. As business firms now manufacture parts of their products across the border, bilateral trade agreements (BTAs), regional trade agreements (RTAs) and free trade agreements (FTAs) of the contemporary period need to take into account the new kind of trade barriers that have been created due to the changing mode of trade. The contemporary regional agreements need to be designed to facilitate the new modes of conducting business and trade. It was understood rather late in Asia that the ‘WTO-Plus’ FTAs are more functional and result-oriented than their predecessors.

The Effectiveness of Noninvasive Positive Pressure Ventilation in Subarachnoid Pleural Fistula: A Case Report and Literature Review

Dilip Chand Raja Soundararajan,Ajoy Prasad Shetty,Rishi Mugesh Kanna,,S Rajasekaran 대한척추신경외과학회 2018 Neurospine Vol.15 No.4

Subarachnoid pleural fistula (SPF) is an aberrant communication between the pleural cavity and subarachnoid space, resulting in uncontrolled cerebrospinal fluid drainage. The negative pressure of the pleural cavity creates a continuous suctioning effect, thereby impeding the spontaneous closure of these fistulas. Dural tears or punctures in cardiothoracic procedures, spinal operations, and trauma are known to cause such abnormal communications. Failure to recognize this entity may result in sudden neurological or respiratory complications. Hence, a high index of suspicion is required for early diagnosis and prompt management. Noninvasive positive pressure ventilation has been described to be effective in managing such fistulas, thus mitigating the high morbidity associated with exploratory surgery for primary repair. Herein, we describe the typical presentation of SPF and the clinical course, treatment, and follow-up of a patient who sustained SPF following anterior thoracic spinal surgery.

Sequences in Financial Liberalization in the Emerging-Market Economies: Growth, Volatility or Both?

( Dilip K. Das ) 세종대학교 경제통합연구소 (구 세종대학교 국제경제연구소) 2004 Journal of Economic Integration Vol.19 No.4

The objective of this paper is to in-depth study the financial liberalization process in the various segments of the emerging-market economies and observe whether the resulting assertion of fast-clip real GDP growth holds. The author examines financial and macroeconomic turbulence in the emerging market economies during the 1990s and early 2000s, which gave a new perspective to the financial liberalization process. It was believed that capital account liberalization led to volatility in the capital market as well as macroeconomic volatility, which in turn led to a support for the strategy of restrictive global capital flows. The unrestricted trans-border capital flows were blamed for disorderly, if on occasion totally erratic, capital market behavior, both domestically and globally. After taking a long-term perspective on financial repression and financial liberalization, the author focuses on the liberalization-growth nexus. Capital account liberalization and whether it leads to growth and/or volatility or both are the issues are the next point of analyses. Relatively recent phenomenon of liberalization in equity markets, its pace and intensity, has also been delved into. Whether the recent spate of emerging-market crises bore a relationship with the financial liberalization is the other focus of this paper.

Study of Dynamic Mechanical Properties and Morphological Behaviours of Fly AshReinforced Polypropylene Composites

Dilip C. D. Nath,Sri Bandyopadhyay,John Rider,Aibing Yu,Darryl Blackburn,Chris White 한국고분자학회 2011 Macromolecular Research Vol.19 No.4

isotactic-Polypropylene (PP) composites reinforced with 20, 45, and 60 wt% fly ash (FA) were prepared by injection molding at 483 K. The thermo-mechanical and morphological behaviors of PP and composites were examined. The addition of FA led to significant enhancement of both storage (E') and loss modulus (E'') of the composites compared to those of PP at a given temperature, supporting the view of the formation of an interfacial interaction between the surfaces of PP and FA. By increasing the temperature from 303 to 423 K, these properties decreased exponentially, and indicated the temperature-activated mobility of segmental chains of PP. The tangent δcurves of PP and composites showed broader patterns. The glass transition temperature (Tg) was assigned at 343 K for PP and 245-246 K for the composites. In the theoretical calculation of the storage modulus and tangent δ, the modifications were required in the existing equations to fit the experimental data well. Scanning electron microscopy (SEM) revealed a uniform distribution of spherical FA particles in the composites. The calculated interfacial interaction between the FA and PP surfaces was 1.85, which is similar with other composite systems.

What impacts the structural breaks in volatility transmission from crude oil to agricultural commodities?

Dilip Kumar 한양대학교 경제연구소 2019 JOURNAL OF ECONOMIC RESEARCH Vol.24 No.1

The paper examines the evolution of volatility transmission from thecrude oil market to agricultural commodities during the period from1983 to 2015 based on the unbiased version of Rogers and Satchell(1991) volatility estimator, hereafter referred as the AddRS estimator. Our findings indicate that the dynamics of volatility transmission fromcrude oil to the given agricultural commodity is structurally unstableand exhibits structural breaks. We find that the structural breaks involatility series play a tiny role in explaining the structural breaks inthe measured volatility transmission from crude oil to the givenagricultural commodities. However, we find that the conditionalheteroskedasticity plays a significant role in explaining the structuralbreaks in measured volatility transmission from crude oil toagricultural commodity. The economic significance analysis indicatesthat the information from the crude oil market can be used to earnsubstantial economic gain in returns by investing in agriculturalcommodities.

China’s Contribution to Recent Convergence and Integration among the Asian Economies

Dilip K. Das 대외경제정책연구원 2013 East Asian Economic Review Vol.17 No.1

The objective of this article is to explore the economic relationship between China and the surrounding dynamic Asian economies. It delves into China’s influence over the Asian economies and whether this relationship is a market-led or de facto symbiosis. The three principal channels of regional integration analyzed in this article are trade, FDI and vertically integrated production networks. They are essentially based on the activities of the private-sector in these economies. China methodically expanded and deepened its economic ties with the regional neighbors. At the present juncture, China’s integration with the surrounding Asia is deep. Another issue that this article explores is the so-called China “threat” or “fear” in Asia. It implies that China is crowding out exports of the other Asian economies in the world market place. Also, as China has become the most attractive FDI destination among the developing countries, it is apprehended that China is receiving FDI at the expense of the Asian economies. These concerns were examined by several empirical studies, and the inference is that they are exaggerated. This article concludes that the private-sector business activities in China and other rapidly growing Asian economies were (and are) instrumental in bringing together the production structures and real economies. The result is both convergence and integration among the dynamic Asian economies. Over the years China and its Asian neighbors has developed a close and symbiotic economic relationship and a de facto regional integration.
