  • Objective:Under the hypothesis that 5-HTTLPR polymorphism plays some role in the susceptibility or vulnerability of some subgroup of alcohol dependence, associations of 5-HTTLPR polymorphism with alcohol dependence were examined. Method:This association analysis included 109 Korean alcohol dependent and 113 Korean control subjects. DNA of all subjects were genotyped for the biallelic functional polymorphism in the 5-HTTLPR. Considering the likelihood of heterogeneity in the alcohol dependence phenotype, alcohol dependent subjects were subgrouped by onset age, family history of alcohol dependence and severity of withdrawal symptoms. Results:There were no significant differences in the frequencies of either the 5-HTTLPR genotype or the short vs. long allele in alcohol dependent and control subjects. The frequency of the S allele and S-carrier (LS or SS genotype) was significantly increased in the early onset alcohol dependent subjects and the familial alcohol dependent subjects compared with that in the control subjects. Conclusion:The results suggest that the 5-HTT 'S' promoter polymorphism is associated with an increased susceptibility or vulnerability to develop early onset alcohol dependence and familial alcohol dependence, which characterize Cloninger's type 2 alcohol dependence.

  • Tea leaves are major source of catechins—antioxidant flavonoids. Dihydroflavonol 4-reductase (DFR, EC 1.1.1.219) is one of the important enzymes that catalyzes the reduction of dihydroflavonols to leucoanthocyanins, a key ''late'' step in the biosynthesis of catechins. This manuscript reports characterization of DFR from tea (CsDFR) that comprised 1,413 bp full-length cDNA with ORF of 1,044 bp (115-1,158) and encoding a protein of 347 amino acids. Sequence comparison of CsDFR with earlier reported DFR sequences in a database indicated conservation of 69-87% among amino acid residues. In silico analysis revealed CsDFR to be a membrane-localized protein with a domain (between 16 and 218 amino acids) resembling the NAD-dependent epimerase/dehydratase family. The theoretical molecular weight and isoelectric point of the deduced amino sequence of CsDFR were 38.67 kDa and 6.22, respectively. Upon expression of CsDFR in E. coli, recombinant protein was found to be functional and showed specific activity of 42.85 nmol $min^{-1}$ mg $protein^{-1}$. Expression of CsDFR was maximum in younger rather than older leaves. Expression was down-regulated in response to drought stress and abscisic acid, unaffected by gibberellic acid treatment, but up-regulated in response to wounding, with concomitant modulation of catechins content. This is the first report of functionality of recombinant CsDFR and its expression in tea.

  • As the obesity has been known to be related with the hyperlipidemia, cardiovascular disease, cerebral apoplexy, fatty liver, and other chronic diseases, recent researches have focused on the functional food materials and their anti-obesity activities. This study was performed to study the effects of vanilloid family capsaicin, major pungent ingredient of hot chillies and peppers, on anti-obesity activities. ICR male mice were fed one of the pellet diet, basal diet, and high fat diet with capsaicin (45 $\mu\textrm{g}$/day) solution for 5 days. Mice in the corresponding control groups were given water for 5 days. In results, capsaicin reduced body weights in any diet groups. Percent weight and cell size of the abdominal white adipose tissue in mice on the high fat diet with capcaicin were significantly lower compared with those in mice on the high fat diet with water. However, percent brown adipose tissue weight per body weight in mice on the high fat diet was not affected by capsaicin. Capsaicin reduced the levels of s-triglyceride and s-total cholesterol in the pellet diet or high fat diet groups. There was no difference in the s-protein levels between the capsaicin group and the control water group. These data indicate that 1) orally administered capsaicin has a reducing effect on the blood triglyceride and total cholesterol levels, and 2) capsaicin has lowering effects on the body weight, percent weight and cell size of the abdominal white adipose tissue.

  • The phytopathogenic fungus Magnaporthe oryzae is a major limiting factor in rice production. To understand the genetic basis of M. oryzae pathogenic development, we previously analyzed a library of T-DNA insertional mutants of M. oryzae, and identified ATMT0879A1 as one of the pathogenicity-defective mutants. Molecular analyses and database searches revealed that a single TDNA insertion in ATMT0879A1 resulted in functional interference with an annotated gene, MGG00056, which encodes a short-chain dehydrogenase/reductase (SDR). The mutant and annotated gene were designated as $MoSDR1^{T-DNA}$ and MoSDR1, respectively. Like other SDR family members, MoSDR1 possesses both a cofactor-binding motif and a catalytic site. The expression pattern of MoSDR1 suggests that the gene is associated with pathogenicity and plays an important role in M. oryzae development. To understand the roles of MoSDR1, the deletion mutant ${\Delta}Mosdr1$ for the gene was obtained via homology-dependent gene replacement. As expected, ${\Delta}Mosdr1$ was nonpathogenic; moreover, the mutant displayed pleiotropic defects in conidiation, conidial germination, appressorium formation, penetration, and growth inside host tissues. These results suggest that MoSDR1 functions as a key metabolic enzyme in the regulation of development and pathogenicity in M. oryzae.

  • Masstige goods aimed consumers who want the fame and the emotional contents with reasonable price are presented overall and around the life style, from all the fashion items like bag and apparel to car, electric household, food, sports goods, furniture, toys, pets and performance of art, etc. Masstige casual, essentially different from the passed casuals which emphasized only price strategy, appeals to teenagers and young of twenties with a definite brand concept. Therefore masstige casual might be separated from business casual of a target aged thirties. Established celebrity brands have launched masstige brands matching the popularization of prestige goods. Armani Exchange from Armani, Marc by Marc Jacobs from Louis Vuitton are representative ones. DKNY from Donna Karen, MiuMiu from Prada, Paul smith Pink from Paul Smith can be added. These are relatively inexpensive, however the quality, design and shop's atmosphere are more exclusive than general brands. Consumers are over middle class and have a pride and fidelity to those brands. Leading Masstige trend, new luxury brands put the importance to the quality and aims middle class. To succeed in this field, companies should know exactly what consumers want, considering not only functional aspect but also emotional pleasure. Even though masstige has a weakness in pricing, it has to keep brand's proper benefit. Its price range could be wide to be in great demand but has to have elasticity and not to be expanded too much. Masstige industry should do its best not to damage original brand's identity. Forming family brand, like Armani made Georgic Armani, Emporio Armani and Armani exchange, system of parent brand and sub brands would be recommendable. From the launching time, masstige needs the effects to create a sensation and bring it into vogue and offer emotional value to the consumers.

  • BACKGROUND/OBJECTIVES: Hypertriglyceridemia may be a more important predictor of cardiovascular disease in Asian population consuming carbohydrate-rich foods than in Western populations. Dairy products are known to play a beneficial role in obesity, dyslipidemia, and metabolic syndrome, but the results vary depending on gender and obesity. In this study, we investigated the associations between dairy product intake and hypertriglyceridemia in Korean adults. SUBJECTS/METHODS: The participants were selected from the Korea National Health and Nutrition Examination Survey 2007-2012 (KNHANES IV and V). A total of 22,836 participants aged 19-64 years were included in the analysis. A food frequency questionnaire used to determine the frequency of consumption of products (milk and yogurt). Multivariable logistic regression was used to assess the associations between dairy product intake and hypertriglyceridemia. RESULTS: A significantly decreased risk of hypertriglyceridemia was detected in the highest dairy product intake frequency group (≥ 1 time/day) (odd ratio [OR] = 0.79; 95% confidence interval [CI] 0.64-0.97, P for trend = 0.022) compared to that for the lowest dairy product intake frequency group. Among obese participants, the group with the highest intakes of milk (in men, OR = 0.64; 95% CI: 0.46-0.91, P for trend = 0.036) and yogurt (in women; OR = 0.53; 95% CI: 0.29-0.94, P for trend = 0.019) showed inverse associations with hypertriglyceridemia. No associations were detected in normal weight participants. CONCLUSION: The association between dairy product intake and hypertriglyceridemia differed by gender and obesity status. Further prospective studies are needed to confirm these associations.

  • A novel protease gene from Bacillus gibsonii, aprBG, was cloned, expressed in B. subtilis, and characterized. High-level expression of aprBG was achieved in the recombinant strain when a junction was present between the promoter and the target gene. The purified recombinant enzyme exhibited similar N-terminal sequences and catalytic properties to the native enzyme, including high affinity and hydrolytic efficiency toward various substrates and a superior performance when exposed to various metal ions, surfactants, oxidants, and commercial detergents. AprBG was remarkably stable in 50% organic solvents and retained 100% activity and stability in 0-4 M NaCl, which is better than the characteristics of previously reported proteases. AprBG was most closely related to the high-alkaline proteases of the subtilisin family with a 57-68% identity. The secretion and maturation mechanism of AprBG was dependent on the enzyme activity, as analyzed by site-directed mutagenesis. Thus, when taken together, the results revealed that the halo-solvent-tolerant protease AprBG displays significant activity and stability under various extreme conditions, indicating its potential for use in many biotechnology applications.

  • Exposure to some synthetic environmental chemicals and their metabolites cause reproductive problems in a variety of vertebrate via endocrine mechanisms. However, in most cases, the link between these compounds and adverse effects on humans, fish, and wildlife has not been established, which necessitates a closer look at the molecular, functional, and clinical implications of these chemicals in the environment. Calbindin-D9k (CaBP-9k) is a member of a largo family of intracellular calcium binding proteins that have high affinities for calcium. It was reported that the estrogen level of uterus affected the expression of the CaBP-9k gene in rat uterus. We examined the dose-dependent CaBP-9K gene expression in the uterus for three-days injection of methoxychlor (HC) in the overectomized immature rats and the relation with uterotrophic response of the compoundsand compared the responses induced by MC according to the route of administration.

  • This study is purposed to understand the spacial usage of the furniture in detail for interior architecture. Many documents have prescribed the spacial furniture at random. While modernist have been interested in the spacial usage of the furniture, the importance of the spacial furniture stands out in architectural space. Since long ago, a great deal of effort has been put into creating a relational harmony between the space and furniture. The villa, the weekend home of the Savoye family, was built between 1928 and 1931. Particularly, the villa Savoye was focused for this study. Le Corbusier viewed desks and case pieces for storage as architecture, and the unite furniture and architecture by developing cabinets in standard modules that could be painted either the wall color to become part of the wall or in contrasting colors to stand out as furniture. Spacial furniture was used architecturally in the interior as well, it gives the space an unexpected playfulness with the color of the finishing materials. The various usage of the Spacial furniture constitute an element of great architectural richness. They have a unique principle based on emotional order and make the man move to another space and experience the spacial connection. In particular, the furniture that was considered by Corbuisier have rational function, division of the space, leaning the structure, and so on. The furniture as the element of the space composition can change the architectural space and view as well as connecting each other. Spacial furniture appear as physical ones called wall, floor, column, and existential value as a living space.

  • Mankind has been attempting to live a happy and safe family life in a residential space. Due to the advent of the mobile phone in the 1990s and the smart phone in the 2000s, when the information and communication age came, human life has been innovatively changed. The revolution of human civilization led to the Neolithic Revolution and the Iron Age, followed by a smart phone revolutionizing human life, and the revolution faces with the era of info-communication, smart phones became a daily life and the fourth industrial revolution. The fourth industrial revolution is an era of info-communication technology (ICT), creating a new paradigm across human life through technological developments such as artificial intelligence (AI), IoT, big data, mobile, and cloud. The smart home is actively researched in a direction to support the overall human life as a representative future residential culture paradigm. However, the study considering the needs according to the lifestyle, functional characteristics of each living space and human lifestyle of the Phono Sapiens era where smart phones live like daily life was relatively insufficient. In addition, research on smart home service design should be considered from the apartment residential space planning stage. Therefore, this study has significance in suggesting the direction of research on human-centered smart home service design considering the characteristics of each living space and resident's life-style in the smart phone era.
