Outward Foreign Investment Policy in Korea: A Review on Policy Issues and Performance
Pattnaik Chinmay,Ki-Hwan Kwo 한국무역학회 2006 Journal of Korea trade Vol.10 No.3
Korea made substantial efforts to integrate its economy with more globalized economies during the 1990s. For its future competitiveness, every sphere of the Korean national economy has witnessed major policy changes to integrate the domestic economy with the cross-bordering economy. The outward foreign investment policy, among all of the domestic economic policy changes, has undergone a key transformation to enable Korean firms to go abroad. This paper traces the origin and evolution of Korean outward foreign investment policies over the last four decades in response to the changes in the global economy. Moreover, this paper describes the transformation of the role of the Korean government in three different phases and identifies the recent issues in outward foreign investment in Korea.
A Semi-supervised Learning of HMM to Build a POS Tagger for a Low Resourced Language
Pattnaik, Sagarika,Nayak, Ajit Kumar,Patnaik, Srikanta The Korea Institute of Information and Commucation 2020 Journal of information and communication convergen Vol.18 No.4
Part of speech (POS) tagging is an indispensable part of major NLP models. Its progress can be perceived on number of languages around the globe especially with respect to European languages. But considering Indian Languages, it has not got a major breakthrough due lack of supporting tools and resources. Particularly for Odia language it has not marked its dominancy yet. With a motive to make the language Odia fit into different NLP operations, this paper makes an attempt to develop a POS tagger for the said language on a HMM (Hidden Markov Model) platform. The tagger judiciously considers bigram HMM with dynamic Viterbi algorithm to give an output annotated text with maximum accuracy. The model is experimented on a corpus belonging to tourism domain accounting to a size of approximately 0.2 million tokens. With the proportion of training and testing as 3:1, the proposed model exhibits satisfactory result irrespective of limited training size.

The study evaluated different synthetic and semisynthetic media for maximal recovery of rumen bacteria and expression of their antibacterial activity. Rumen Glucose Cellobiose Agar (RGCA) medium was found to be the best for recovery of rumen bacteria. However, L-10 medium was the best for expression of antibacterial activity of ruminal isolates followed by Easy, M-10, RGCA and M-98-5 medium. The present study recommends the use of L-10 medium as the medium of choice for screening of antibacterial activity of ruminal isolates. Comparative evaluation of bacterial counts on different dietary regimes indicated significant difference between different growth media on a specific diet and between diets on specific growth media within a species. However, there is no overall significant difference between total bacterial counts obtained from rumen liquor of cattle and buffalo with respect to either the feeding regime or growth media. Feeding straw based diet to the animal is the best for high recovery of rumen bacteria.

This study examines the differences in information asymmetry of firms affiliated with business groups and unaffiliated firms in India using analysts’ forecast error and dispersion data covered by the I/B/E/S database. Empirical results show that firms affiliated with business groups have higher information asymmetry, leading to higher analyst forecast error and dispersion, than unaffiliated firms. This study also finds that group-affiliated firms with more intra-group capital transactions have higher forecast error and dispersion. The above evidence suggests that while business groups can create value by efficiently substituting internal markets for the imperfect external markets prevalent in emerging markets, their dominance curtails the development of efficient external markets. Due to their reliance on internal markets, group-affiliated firms have little motivation or incentive to disclose information. As a result, the need for market intermediaries, like stock analysts, is minimal, or their operation is negatively affected, limiting the development of vibrant capital markets in emerging markets.

Objectives: The purpose of this study was to evaluate the influence of eye dominance on color perception, and shade matching. Materials and Methods: A total of 104 participants were selected for the study. There were 3 groups: Group I: 3rd and 4th year dental students and interns (n = 40); Group II: postgraduates (n = 34); Group III: senior residents and faculty members (≥ 6 years of clinical experience) (n = 30). All participants were evaluated for congenital color blindness with Ishihara plates, their dominant eye with Mile's test, and their color perception with the Farnsworth-Munsell 100 hue test. The shade guide test was used for shade matching with a second corresponding set of Vitapan classical shade guides. Results: The results of Mile’s test revealed that 60.6% were right-eye dominant and 39.4% were left-eye dominant. There was a statistically significant difference among all participants between the dominant eye and the non-dominant eye in shade matching. Conclusions: The dominant eye has a positive effect on shade matching and the ability to match shades becomes better with an increase in clinical experience.

Combating pollution caused by nondegradable thermoplastics is a significant challenge keeping in view of their marginalcost, mechanical strength and ease of use for the production of esthetic products. Only low-cost/waste natural fiber-reinforcedcomposites provide a ray of hope for replacing the aforementioned composites, but these composites have significant limitations,including low mechanical strength and excessive water penetration. Varying the weight percentages of waste vetiverfiber, soy-based composites are fabricated and characterized in this study. The highest tensile and flexural strengths of thevetiver–soy composite are found as 49.78 MPa and 51.4 MPa, respectively. The fabricated composite is moderately hydrophobicin nature, as per the contact angle and water absorption studies. Post-soil burial degradation studies like weight loss,Fourier transform infra-red spectroscopy, and optical micrography revealed that produced composite is totally biodegradablein nature. As a result, vetiver–soy composite will be a viable replacement for plastic and plastic-based items majorly insectors like auto mobile industry and packaging sector.
A Single-Phase Cell-Based Asymmetrical Cascaded Multilevel Inverter
Singh, Varsha,Pattnaik, Swapnajit,Gupta, Shubhrata,Santosh, Bokam The Korean Institute of Power Electronics 2016 JOURNAL OF POWER ELECTRONICS Vol.16 No.2
A single-phase asymmetrical cascaded multilevel inverter is introduced with the goal of increasing power quality with the reduction of power in insulated-gate bipolar transistor (IGBT) switches. In the present work, the proposed inverter topology is analyzed and generalized with respect to different proposed algorithms for choosing different voltage source values. To prove the advantages of the proposed inverter, a case study involving a 17-level inverter is conducted. The simulation and experimental results with reduced THD are also presented and compared with the MATLAB/SIMULINK simulation results. Finally, the proposed topology is compared with different multilevel inverter topologies available in the literature in terms of the number of IGBT switches required with respect to the number of levels generated in the output of inverter topologies.
Sensitivity of Tropical Cyclone Intensity and Structure to Planetary Boundary Layer Parameterization
Deepika Rai,Sandeep Pattnaik 한국기상학회 2018 Asia-Pacific Journal of Atmospheric Sciences Vol.54 No.3
The advanced weather research and forecasting model is used to investigate the influence of planetary boundary layer (PBL) processes on intensity and structure of the storm Phailin (2013). Five simulations are conducted with five PBL schemes; Yonsei University (YSU), Mellor−Yamada−Nakanishi−Niino order2.5 (MYNN2), Assymetric Convective Model2 (ACM2), Medium Range Forecast (MRF), and Bougeault and Lacarrere (BouLac). The simulation duration includes the pre − intensification and rapid intensification phase of Phailin before landfall. Results indicate that during the pre − intensification phase, storm’s track and intensity are not much sensitivity to PBL but structural changes are noted. A significant sensitivity of track and intensity to PBL parameterizations are found during rapid intensification phase. BouLac andMRF produced two extremes with 39 hPa intense and 16 km compact stormfor BouLac thanMRF. Further analysis reveals an outward movement of air parcel just above the boundary layer which causes spin-down for YSU and MYNN2. BouLac is associated with stronger eddy diffusivity and moisture fluxes within the boundary layer and stronger cyclonic vorticity just above the boundary layer than other experiments. Stronger cyclonic vorticity above the boundary layer in BouLac favors intense updraft, facilitatingmoremoisture transport from the boundary layer to upper layers aiding stronger secondary circulation and robustly intensifying the storm. A relatively deeper and drier inflow layer associated with weaker cyclonic vorticity just above the boundary layer reduces the moisture transport and weaken the secondary circulation for MRF than others.
