Trade Opening and the Behavior of Emerging Stock Market Prices
( Parantap Basu ),( Matthew R. Morey ) 세종대학교 경제통합연구소 (구 세종대학교 국제경제연구소) 2005 Journal of Economic Integration Vol.20 No.1
In this paper we develop a model that explores the effect of trade openness on stock price behavior. The model predicts that stock returns show non-zero serial correlation in a closed economy. However, once the country opens on the trade front, the stock returns show zero serial correlation. The reason for the difference is that once the country opens itself to trade, the growth process becomes selfsustained due to optimal use of imported intermediate inputs. Stock prices reflect this gain in productive efficiency by displaying a random walk behavior. The model also establishes that financial opening alone without trade opening will not lead to gain in efficiency in the stock prices.

This research examines cultural influence on the preference of promotive (i.e., trying to eat more healthy foods) and preventive (i.e., trying to avoid unhealthy foods) dietary practices. Survey data were collected from students and older adults in Korea (N = 287) and the U.S. (N = 245). Only students participated in the survey in Japan (N = 145). Consistent with the prediction, Study 1 shows Korean mature adults are more willing to adopt preventive dietary practices, while American counterparts favor promotive eating habits. The pattern of the data was inconsistent with the prediction among student participants across the three nations. Individual-level data from Study 2 (N = 284) confirm that independent self-construal affects promotive dietary practice via increasing promotive regulatory self-focus. The indirect impact of interdependent self-construal on preventive dietary practice was less apparent. Practical implications for doctor-patient communication are discussed.

Objectives: Literature has shown that micro-organisms contaminate gutta percha (GP) during storage and manipulation. Till date herbal extracts are not explored as an alternative medicament for pre-operative chairside disinfection of GP cones. The purpose of our study was to evaluate the antimicrobial activity and efficacy of lemon grass oil (LG), basil oil (BO), and obicure tea extract (OT) in disinfecting GP cones before obturation. Materials and Methods: Agar diffusion method was used to evaluate the antimicrobial efficacy of LG, BO, OT, and sodium hypochlorite (control) against common contaminants, namely, Enterococcus faecalis, Staphylococcus aureus, and Candida albicans. One hundred and twenty GP cones were contaminated and cut into 2. First half was placed in the broth and incubated; whereas the second was treated with herbal extracts for 1 minute and then incubated for 24 hours in the broth. Any inhibition in bacterial growth was noted with presence/absence of turbidity. Two-way analysis of variance and ${\chi}^2$ test were used to assess the effectiveness of herbal extracts to decontaminate GP. Results: LG showed the highest inhibition zones ($29.9{\pm}6.9mm$) for all tested organisms, followed by OT extract ($16.3{\pm}1.8mm$), sodium hypochlorite ($16.0{\pm}1.6mm$), and BO ($14.5{\pm}5.3mm$). Statistically significant difference was observed between LG and other herbal extracts (p < 0.05). Conclusions: All extracts proved to be potential rapid chairside disinfectants of GP cones with LG showing the highest antimicrobial activity.

Torrefaction technologies convert assorted biomass feedstocks into energy-concentrated, carbon neutral fuel that is economically transported and easily ground for blending with fossil coals at numerous power plants around the world without needs to retrofit. Utilization of torrefied biomass in conventional electric generating units may be an increasingly attractive alternative for electricity generation as aging power plants in the world need to be upgraded or improved. This paper examines the economic feasibility of torrefaction in different scenarios by modeling torrefaction plants producing 136,078 t/year (150,000 ton/year) biocoal from wood and corn stover. The utilization of biocoal blends in existing coal-fired power plants is modeled to determine the demand for this fuel in the context of emerging policies regulating emissions from coal in the U.S. setting. Opportunities to co-locate torrefaction facilities adjacent to corn ethanol plants and coal-fired power plants are explored as means to improve economics for collaborating businesses. Life cycle analysis was conducted in parallel to this economic study and was used to determine environmental impacts of converting biomass to biocoal for blending in coal-fired power plants as well as the use of substantial flows of off-gasses produced in the torrefaction process. Sensitivity analysis of the financial rates of return of the different businesses has been performed to measure impacts of different factors, whether input prices, output prices, or policy measures that render costs or rewards for the businesses.

Purpose: We sought to determine whether early clinical performance of new posterior stabilized (PS) knee system, the Vega-PS (Aesculap), is better than that of two established total knee arthroplasty (TKA) prostheses, the E.motion-PS (Aesculap) and the Genesis II (Smith & Nephew) in terms of functional outcomes, patient satisfaction, and incidence of adverse events. Materials and Methods: We compared the clinical outcomes of 206 consecutive TKAs using Vega-PS with those of 205 TKAs using E.motion-PS and 216 TKAs using Genesis II at 2 years of follow-up. Results: Overall, the knees with the Vega-PS had better functional outcome scores than the knees with the E.motion-PS, but had similar outcome scores to the knees with the Genesis II, as evident from the American Knee Society knee score (94.2 vs. 92.5 vs. 93.2), Western Ontario McMaster Universities Osteoarthritis (WOMAC) stiffness index (1.8 vs. 2.3 vs. 2.0), WOMAC function index (11.8 vs. 16.8 vs. 18.5), Short Form 36 (SF-36) physical component summary score (41.9 vs. 39.3 vs. 41.6), and SF-36 mental component summary score (50.0 vs. 45.8 vs. 46.9). Patient satisfaction was higher in the Vega-PS and Genesis II groups than the E.motion-PS group. No notable group differences were found in terms of the incidence of adverse events. Conclusions: The Vega-PS, a newly developed PS fixed bearing prosthesis, had comparable or superior clinical performance in comparison with the two established fixed or mobile bearing PS prostheses.

<P><B>Summary</B></P><P>Genomic stability is critical for the clinical use of human embryonic and induced pluripotent stem cells. We performed high-resolution SNP (single-nucleotide polymorphism) analysis on 186 pluripotent and 119 nonpluripotent samples. We report a higher frequency of subchromosomal copy number variations in pluripotent samples compared to nonpluripotent samples, with variations enriched in specific genomic regions. The distribution of these variations differed between hESCs and hiPSCs, characterized by large numbers of duplications found in a few hESC samples and moderate numbers of deletions distributed across many hiPSC samples. For hiPSCs, the reprogramming process was associated with deletions of tumor-suppressor genes, whereas time in culture was associated with duplications of oncogenic genes. We also observed duplications that arose during a differentiation protocol. Our results illustrate the dynamic nature of genomic abnormalities in pluripotent stem cells and the need for frequent genomic monitoring to assure phenotypic stability and clinical safety.</P> <P><B>Highlights</B></P><P>► hESCs and hiPSCs show more gene copy number variation than somatic cells ► Degree of abnormality differs more between hESC lines than hiPSC lines ► Deletions common in hiPSCs after reprogramming, duplications appear over time ► Recurrent duplications occur at specific genomic loci in pluripotent cells</P>
