  • This presentation explores on the perceptual characteristics of the lateral sound /l/ in CV syllables. At initial position we found that /l/ has well marked formant transitions. Then several questions arise: 1) are these formant structures dependent on the following vowel\ulcorner. 2) Are the formant transitions giving an additional cue for the identification\ulcorner Considering that the French vocalic system presents a greater variety of vowels than Spanish, several experiments were designed to verify to what extent a more extensive range of vocalic timbres contribute to the perception of /l/. Natural emissions of /l/ produced in Argentine Spanish and Canadian French CV syllables were recorded, where V was successively /i, e, a, o, u/ for Spanish and /i, e, $\varepsilon$, a, $\alpha$, o, u, y, \phi$/ for French. For each item, the segment C was maintained and V was replaced by cutting & splicing by each of the remaining vowels without transitions. Results of the identification tests for Spanish show that natural /l/ segments with low Fl and high formants F3, F4 can be clearly identified in the /i, e, u/ vowel contexts without transitions. For French subjects the combination of /l/ with a vowel without transitions reflected correct identifications for its own original vowel context in /e, $\varepsilon$, y, $\phi$/. For both languages, in all these combinations, F1 values remained rather steady along the syllable. In the case of /o, u/ very likely the F2 difference lead to a variety of perceptions of the original /l/. For example in Ilul, French subjects reported some identifications of /l/ as a vowel, mainly /y/. Our observations reinforce the importance of F1 as a relevant cue for /l/, and the incidence of the relative distance between formants frequencies of both components.

  • Constitutional RB1 gene mutations were studied in a series of 21 families with unilateral and bilateral retinoblastoma patients. Peripheral blood lymphocytes were analyzed by "exon by exon" PCR-heteroduplex and sequencing. Mutations were identified in 6 (29%) of the patients. One mutation corresponded to an intronic polymorphism in g.174351T > A. The other five mutations resulted C to T exonic transitions, four were CGA sequences (g.65386, g.150037 in two patients, and g.162237), creating stop codons and presumably truncated proteins. The fifth one was new and resulted in alanine to valine substitution (g.73774). Two patients had the same the germline truncated mutation (g.150037C > T), one with a familial bilateral early onset retinoblastoma and one with a sporadic unilateral late onset retinoblastoma. The later type has not been previously described. This finding is discussed in the genotype/phenotype correlation context. Additionally, a single nucleotide change was found in six studied samples, where a C to T homozygous transversion was identified in intron 26 (IVS26 + 28). It is worthy the non concordance of the nucleotide with the published sequence. This analysis proved to be a useful method for the detection of mutations in the RB1 gene, and contributed to the adequate genetic counseling to patients and relatives.

  • Five barrows (average initial body weight 58.6 kg) were used to determine the apparent ileal digestibilities of amino acids, DM, N and energy in various soybean meal, rapeseed meal and coconut meal in finishing pigs. Dietary treatments included 1) KSBM (Korean soybean meal), 2) CSBM (Chinese soybean meal), 3) ASBM (Argentine soybean meal), 4) RSM (Rapeseed meal), and 5) CNM (Coconut meal). The diets were corn starch-based and formulated so that each protein source provided the same amount of total ME (3,490 kcal/kg), CP (15.70%), lysine (1.00%), Ca (0.80%) and P (0.60%). Protein content of the KSBM was higher than the CSBM and ASBM, with all values similar to those expected, and protein content of the CNM was lower than that of the SBM preparation and RSM. Apparent ileal digestibilities of histidine, lysine, threonine, alanine, asparatic acid, cystine, glutamic acid and serine were greater for the KSBM, CSBM, ASBM and RSM than for the CNM (p<0.05). Also, the apparent ileal digestibilities of methionine, leucine, phenylalanine, valine and tyrosine were greater for the KSBM than for the CSBM, ASBM, RSM and CNM (p<0.05). Overall, the apparent ileal digestibilities of total essential amino acids were greater for the KSBM than for the CSBM, ASBM, RSM and CNM (p<0.05), and the apparent ileal digestibilities of total non essential amino acids were greater for the KSBM, CSBM, ASBM and RSM than for the CNM (p<0.05). No difference (p>0.05) in apparent digestibility of DM at the small intestine was observed among the treatments. However, the apparent digestibility of DM at the total tract was greater for the KSBM than for the CSBM, ASBM, RSM and CNM (p<0.05). Also, apparent digestibilities of N and digestible energy at the small intestine and total tract were greater for the KSBM than for the RSM and CNM (p<0.05). In conclusion, nutrient digestibility values of SBM preparations and RSM were relatively high compared to CNM.

  • This study investigated species identification and labeling compliance of 48 shrimp products sold in the Korean online markets. Species identification was conducted using the standard DNA barcoding method, using the cytochrome c oxidase subunit I gene. The obtained sequences were compared with those deposited in the NCBI GenBank and BOLD Systems databases. Additionally, phylogenetic analysis was performed to further verify the identified shrimp species. Consequently, 16 shrimp species were identified, including Penaeus vannamei, Pandalus borealis, Palaemon gravieri, Leptochela gracilis, Penaeus monodon, Pleoticus muelleri, Metapenaeopsis dalei, Euphausia pacifica, Lebbeus groenlandicus, Trachypenaeus curvirostris, Argis lar, Metanephrops thomsoni, Metapenaeopsis barbata, Alpheus japonicus, Penaeus chinensis, and Mierspenaeopsis hardwickii. The most prevalent species was Penaeus vannamei, found in 45.8% of the analyzed products. A significant mislabeling rate of 72.9% was found; however, upon excluding generic names such as shrimp, the mislabeling rate reduced to 10.4%. The mislabeling rate was higher in highly-processed products (89.3%) compared with that in minimally-processed products (50%). No correlation was found between the country of origin and mislabeling rate. The results of this study provide crucial data for future monitoring of shrimp products and improving the labeling of shrimp species in Korea.

  • One of the controversial issues in investor-state investment arbitration is the interpretation of "umbrella clause" that is found in most BIT and FTAs. This treaty clause requires on Contracting State of treaty to observe all investment obligations entered into with foreign investors from the other Contracting State. This clause did not receive in-depth attention until SGS v. Pakistan and SGS v. Philippines cases produced starkly different conclusions on the relations about treaty-based jurisdiction and contract-based jurisdiction. More recent decisions by other arbitral tribunals continue to show different approaches in their interpretation of umbrella clauses. Following the SGS v. Philippines decision, some recent decisions understand that all contracts are covered by umbrella clause, for example, in Siemens A.G. v. Argentina, LG&E Energy Corp. v. Argentina, Sempra Energy Int'l v. Argentina and Enron Corp. V. Argentina. However, other recent decisions have found a different approach that only certain kinds of public contracts are covered by umbrella clauses, for example, in El Paso Energy Int'l Co. v. Argentina, Pan American Energy LLC v. Argentina and CMS Gas Transmission Co. v. Argentina. With relation to the exhaustion of domestic remedies, most of tribunals have the position that the contractual remedy should not affect the jurisdiction of BIT tribunal. Even some tribunals considered that there is no need to exhaust contract remedies before bringing BIT arbitration, provoking suspicion of the validity of sanctity of contract in front of treaty obligation. The decision of the Annulment Committee In CMS case in 2007 was an extraordinarily surprising one and poured oil on the debate. The Committee composed of the three respected international lawyers, Gilbert Guillaume and Nabil Elaraby, both from the ICJ, and professor James Crawford, the Rapportuer of the International Law Commission on the Draft Articles on the Responsibility of States for Internationally Wrongful Acts, observed that the arbitral tribunal made critical errors of law, however, noting that it has limited power to review and overturn the award. The position of the Committee was a direct attack on ICSID system showing as an internal recognition of ICSID itself that the current system of investor-state arbitration is problematic. States are coming to limit the scope of umbrella clauses. For example, the 2004 U.S. Model BIT detailed definition of the type of contracts for which breach of contract claims may be submitted to arbitration, to increase certainty and predictability. Latin American countries, in particular, Argentina, are feeling collectively victims of these pro-investor interpretations of the ICSID tribunals. In fact, BIT between developed and developing countries are negotiated to protect foreign investment from developing countries. This general characteristic of BIT reflects naturally on the provisions making them extremely protective for foreign investors. Naturally, developing countries seek to interpret restrictively BIT provisions, whereas developed countries try to interpret more expansively. As most of cases arising out of alleged violation of BIT are administered in the ICSID, a forum under the auspices of the World Bank, these Latin American countries have been raising the legitimacy deficit of the ICSID. The Argentine cases have been provoking many legal issues of international law, predicting crisis almost coming in actual investor-state arbitration system. Some Latin American countries, such as Bolivia, Venezuela, Ecuador, Argentina, already showed their dissatisfaction with the ICSID system considering withdrawing from it to minimize the eventual investor-state dispute. Thus the disagreement over umbrella clauses in their interpretation is becoming interpreted as an historical reflection on the continued tension between developing and developed countries on foreign investment. There is an academic and political discussion on the possible return of the Calvo Doctrine in Latin America. The paper will comment on these problems related to the interpretation of umbrella clause. The paper analyses ICSID cases involving principally Latin American countries to identify the critical legal issues arising between developing and developed countries. And the paper discusses alternatives in improving actual investor-State investment arbitration; inter alia, the introduction of an appellate system and treaty interpretation rules.

  • Field studies were conducted from the years 2009 to 2012 in order to determine the cultivation limit as well as to evaluate the characteristics and forage production of warm season grass in Korea. Two bermudagrass [Cynodon dactylon (L.) Pers.] cultivars, two bahiagrass (Paspalum notatum Flugge) cultivars and a Kleingrass [Panicum coloratum L.] cultivar were compared for forage production and quality in the mid-southern regions of Korea. The experimental design was a randomized block design (RBD) with three replications. The number of days to seedling emergence for bremudagrass and bahiagrass was observed as approximately 12 days and 28 days after seeding, respectively. In Kwangju, the heading dates of bahiagrass and kleingrass were 21 August and 10 July, respectively,. Warm season grass did not winter in the mid-regions (Kimjea, Cheonan) of Korea. All of the Bermudagrass cultivars had higher dry matter (DM) than bahiagrass at the first harvest. The dry matter yield of kleingrass was usually greater than the other entries at all study sites. Peak forage DM production of bermudagrass and bahiagrass cultivars occurred in June and July, respectively. The contents of crude protein (CP) and total digestibility nutrient (TDN) for bermudagrass cultivars were usually greater than the other entries at all study sites. Further, acid detergent fiber (ADF) and in vitro DM digestibility (IVDMD) were similar across all cultivars.
