Cytochrome P45O (CYP) 2E1 catalyzes the metabolism of a wide variety of therapeutic agents, procarcinogens, and low molecular weight solvents. CYP2E1-catalyzed metabolism may cause toxicity or DNA damage through the production of toxic metabolites, oxygen radicals, and lipid peroxidation. CYP2E1 also plays a role in the metabolism of endogenous compounds including fatty acids and ketone bodies. The regulation of CYP2E1 expression is complex, and involves transcriptional, post-transcriptional, translational, and post-translational mechanisms. CYP2E1 is transcriptionally activated in the first few hours after birth. Xenobiotic inducers elevate CYP2E1 protein levels through both increased translational efficiency and stabilization of the protein from degradation, which appears to occur primarily through ubiquitination and proteasomal degradation. CYP2E1 mRNA and protein levels are altered in response to pathophysiologic conditions by hormones including insulin, glucagon, growth hormone, and leptin, and growth factors including epidermal growth factor and hepatocyte growth factor, providing evidence that CYP2E1 expression is under tight homeostatic control.

The aim of this study was to investigate the growth performance between two different crossbred strains of Korean native chickens denoted as 1E and 2E with a white semibroiler (LL) from hatch to d-84 post-hatch. A total of 450 one-day-old chicks were randomly distributed into cages which included 15 replicate cages each for 1E and 2E with 9 replicate cages for LL. A three phase feeding program was used as a starter (Day 1 - 35; crude protein [CP] 20.3%; metabolizable energy [ME] 3,059 kcal·kg^-1), grower (Day 36 - 56; CP 18.6%; ME 3,123 kcal·kg^-1) and finisher (Day 57 - 84; CP 16.7%; ME 3,187 kcal·kg^-1). The results revealed that LL had a higher (p < 0.05) BW during d-8 to d-84 compared with the other two cross breed groups. A higher (p < 0.05) ADG was observed from the LL during the entire period except from d-1 to d-14 and d-71 to d-84 when compared with 1E and 2E. Shank length did not vary (p > 0.05) between the strains, despite LL having a SL that was 2.86% higher (p < 0.05) when compared with the other strains from d-15 to d-21 post-hatch, and 1E had a SL that was 2.28% (p < 0.05) higher when compared with the other strains during the first week of the experiment.

Recently, ordinary mail is decreasing continuously by the development of ICT (Information and Communications Technology) including E-mail, messenger service, and etc. On the contrary, parcel post is increasing by the increase of online shopping, home shopping, and etc. Aside from these changes, the demand for various mail acceptance and delivery means is increasing with the increase of single households and dual-income couples. To overcome these environmental changes, Korea Post installs unmanned post offices which are composed of various unmanned mail acceptance and delivery postal systems. In this paper, we propose the methodological approach for the site selection of unmanned post office among the existing post offices and the installation standard of unmanned postal system considering the operation cost by the mail volume.

This paper proposes an approach in Southeast Asian studies using a post-colonial framework in the study of post-colonial Southeast Asia. This framework is based on the sociology of knowledge that analyzes the dialectical relationship between science, ideology, and discourse. Post-colonial studies is critical of the concept of universality in science and posits that a scientific statement of a society cannot stand alone, but is made by authors themselves who produce, use, and claim the so-called scientific statement. Several concepts in post-colonial theories can be used to develop area studies, i.e. colonial discourse, subaltern, mimicry, and hybridity. Therefore, this study also explores these concepts to develop a more comprehensive understanding of Southeast Asian culture. The development of post-colonial theories can be used to respond to the hegemony of social theories from Europe and the United States. The main contribution of area studies in the field of the social sciences and humanities is in revealing the hidden interests behind the universal social sciences.

An impeller is difficult to machine because of severe collision due to the complex shape, overlapping and twisted shape that form impeller blades. So, most CAM software companies have developed CAM module for manufacturing impeller in addition to their CAM software. But it is not still easy for inexperienced users to machine impellers. The purpose of this paper is the development of automatic CAM module for manufacturing impeller(E-ICAM) which is based on visual basic language and it is used CATIA graphical environment in order to be easily machining impellers. Automatic CAM module for manufacturing of impellers generates tool path, and proposes recommended cutting condition according to the material of stock and tool. In addition, it has also included a post processor for 5-axis control machining. Therefore the user can easily machine impellers using this automation module.

This study was conducted to compare in vitro rumen fermentation characteristics among corn grains imported from America, Brazil, Argentina and Ukraine A and Ukraine B. Two Holstein steers, each surgically fitted with a ruminal cannula, consuming total mixed ration were used as rumen fluid donors. In vitro rumen fermentation experiments were performed in a completely random design which included a control (no corn) and treatments with 3.0 g of corn from different geographical origins, i.e., America, Brazil, Argentina, and Ukraine A and Ukraine B, respectively. Ruminal pH, ammonia-N, volatile fatty acid (VFA) and total gas production were measured at 0, 1, 3, 6, 12, 24 and 48 h post-incubation, respectively. No differences (p > 0.05) in mean ruminal pH appeared among the treated groups, however, ruminal pH patterns differed; i.e. corn treated groups had dramatically lower pH compared with control during the entire incubation period. Similarly, no different patterns between the groups in ammonia-N (p > 0.05) appeared until 6 h post-incubation. Unexpectedly, higher ammonia-N concentration for control than that for the corn treated groups appeared after 12 h post-incubation despite that for all groups increased. Total VFA was similar between the groups until 6 h post-incubation, but VFA after 12 h post-incubation was different (p < 0.05), i.e. VFA for corn from Argentina, Ukraine A, Ukraine B, and Brazil were comparatively higher than for America. Overall, data in this study showed that the corns of different origins may have different feed values to ruminants despite having similar chemical compositions.

We investigated the effects of antioxidant vitamins supplementation on antioxidative status and plasma lipid profile in female Korean non-insulin diabetes mellitus(NIDDM) patients. Forty-five patients were groups by types of vitamin to take into three groups-Vitam in E group(400IU/day, n=15), Vitamin C group (1,000mg/day, n=15) and Vitamin E plus C group (400 IU plus 1,000mg/day). Supplementation period was 4 weeks. After vitamins supplementation, plasma vitamin E concentration significantly increased in vitamin E and vitamin E + C group, but plasma retinol concentration were not affected by vitamin E or vitamin C supplementation. And plasma levels of lipid peroxide measured as thiobarbituric acid reactive substances(TBARS), indicator of lipid peroxidation and increased susceptibility of LDL towards lipid peroxidation, were significantly decreased in all three groups after vitamins supplementation. Also catalase activities in erythrocytes were significantly decreased after antioxidant vitamin supplementation in all subjects. And after vitamins supplementation, post prandial 2 hour glucose and total cholesterol levels was decreased in all subjects. And after vitamins supplementation, post prandial 2 hour glucose and total cholesterol levels was decreased in all patients, especially there was a significant difference in vitamin C, Vitamin E + C group. In this study, antioxidant vitamins supplementation might have a protective function against the free radical-mediated lipid peroxidation and decrease the plasma total cholesterol levels in Korean female NIDDM patients.
