The purpose of this paper is to argue that the parataxis vs. hypotaxis distinction in English clauses complex is not available for the explanation of the corresponding expressions in Korean target translated texts. This argument comes from the following claims. First, most hypotactic clauses complex in English are translated into the corresponding constructions in Korean with hypotactic connectives in form and meaning. Some of the clauses are translated with paratactic connectives in Korean, but most of them involve the hypotactic meanings. Second, the hypotactic clauses complex in English allow either main + subordinate clause order or subordinate + main clause order, while those in Korean target texts do not permit such alternate orderings. Third, the paratactic constructions involving -ko ‘and’ connectives in Korean target texts are mostly translated with the hypotactic meanings, which shows that those constructions with ‘-ko’ connectives could be classified into hypotactic clauses complex. In conclusion, it is argued from the translational data that the parataxis vs. hypotaxis distinction in English is not important for Korean clauses complex, which shows the neutrality of the distinction in Korean.

Nereistoxin is a natural toxin found in lugworms. Bensultap, cartap, thiocyclam and thiosultap, which are insecticides derived from the molecular structure of nereistoxin, are rapidly converted into nereistoxin in vivo and in the environment after spraying the drug, which binds to nicotinic acetycholine receptor of insects. It shows an insecticidal activity by inhibition of the Na+ and K+ conduction at the end plate membrane, which causes paralysis of central nervous system of insects. In Korea, the definition of residues of bensultap, cartap and thiocyclam is managed as nereistoxin. Currently, the analytical method of nereistoxin residue has a complicated and time-consuming process. Therefore, we tried to improve the usability and efficiency with the QuEChERS (quick, easy, cheap, effective, rugged, and safe) method so that it can be safely converted to nereistoxin. In this study, the validation for the quantitative analysis of nereistoxin was performed, which was verified by the Ministry of Food and Drug Safety. Five agricultural products (mandarin, potato, soybean, hulled rice, and chili pepper) showing group representatives were chosen for experiments. In order to extract, L-cysteine was added into the samples and mixed thoroughly. The samples were heated at 70℃ with 3% nickel chloride and 28% ammonium hydroxide to convert into the nereistoxin rapidly. After addition of sodium chloride and acetonitrile, centrifugation was performed followed by purification using dispersive solid-phase extraction (d-SPE) with anhydrous magnesium sulfate and primary and secondary amine (PSA) to remove the interferences in samples. The results of LC-MS/MS analysis using amide column show the linear standard calibration curves with r-square values higher than 0.99 (coefficient of determination with calibration range) and mean recovery rates of nereistoxin ranged at 84.4~106.2%, the precision less than 12.6% in all five samples. These results are suitable for CODEX guideline for residue analysis (CAC/GL 40). In summary, the proposed method for determination of nereistoxin residue in foods could be included in the Korean Food Code for enabling the safety management of pesticides.

<P>A Disintegrin And Metalloprotease (ADAM) family members expressed in male reproductive tissues are divided phylogenetically into three major groups. In the present study, we analyzed six ADAMs in one of the groups (ADAMs 4, 6, 24, 26, 29, and 30) of which function is largely unknown. Our results showed that most of the ADAMs undergo unique processing during sperm maturation and are located at the surface of sperm head. We found that the levels of ADAM4 and ADAM6 are dramatically reduced in Adam2 and Adam3 knockout sperm defective in various fertilization processes. We observed premature processing of ADAM4 in the Adam3-null mice. Furthermore, we obtained a result showing complex formation of ADAM6 with ADAM2 and ADAM3 in testis. Taken together, these results disclose involvement of ADAM4 and ADAM6 in a reproductive ADAM system that functions in fertilization.</P>

In this study, a real-scale fuel-cell room of volume 1.36 m<sup>3</sup> is constructed to confirm the explosion characteristics of hydrogen-air mixture gas in a hydrogen-powered house. A volume concentration of 40% is applied in the fuel-cell room as the worst-case scenario to examine the most severe accident possible, and two types of doors (made of plastic sheet and wood) are fabricated to observe their effects on the overpressure and impulse. The peak overpressure and impulse based on distance from the ignition source are experimentally observed and assessed. The maximum and minimum overpressures with a plastic-sheet door are about 20 and 6.7 kPa and those with a wooden door are about 46 and 13 kPa at distances of 1 and 5 m from the ignition source, respectively. The ranges of impulses for distances of 1-5 m from the ignition source are about 82-28 Pa·s with a plastic-sheet door and 101-28 Pa·s with a wooden door. The amount of damage to people, buildings, and property due to the peak overpressure and impulse is presented to determine the safe distance; accordingly, the safe distance to prevent harm to humans is about 5 m based on the 'injuries' class, but the structural damage was not serious.

<P>To determine the mechanisms of spermatogenesis, it is essential to identify and characterize germ cell-specific genes. Here we describe a protein encoded by a novel germ cell-specific gene, Mm.290718/ZFP541, identified from the mouse spermatocyte UniGene library. The protein contains specific motifs and domains potentially involved in DNA binding and chromatin reorganization. An antibody against Mm.290718/ZFP541 revealed the existence of the protein in testicular spermatogenic cells (159 kDa) but not testicular and mature sperm. Immunostaining analysis of cells at various stages of spermatogenesis consistently showed that the protein is present in spermatocytes and round spermatids only. Transfection assays and immunofluorescence studies indicate that the protein is localized specifically in the nucleus. Proteomic analyses performed to explore the functional characteristics of Mm.290718/ZFP541 showed that the protein forms a unique complex. Other major components of the complex included histone deacetylase 1 (HDAC1) and heat-shock protein A2. Disappearance of Mm.290718/ZFP541 was highly correlated with hyperacetylation in spermatids during spermatogenesis, and specific domains of the protein were involved in the regulation of interactions and nuclear localization of HDAC1. Furthermore, we found that premature hyperacetylation, induced by an HDAC inhibitor, is associated with an alteration in the integrity of Mm.290718/ZFP541 in spermatogenic cells. Our results collectively suggest that the Mm.290718/ZFP541 complex is implicated in chromatin remodeling during spermatogenesis, and we provide further information on the previously unknown molecular mechanism. Consequently, we re-designate Mm.290718/ZFP541 as 'SHIP1' representing spermatogenic cell HDAC-interacting protein 1.</P>
