  • The purpose of this research was influenced by the historical background of Japanese modern architecture by the circulation of Kuma Kengo's architectural works and he wanted to look at the values and directions he was pursuing and how they were expressed in his works. The results of the review are summarized as follows. First, metabolism was developed as a reaction of modernism in modern architecture, focusing on growth through infinite reproduction by looking at architecture and cities as organisms and by using unit space as cells. Kuma Kengo, on the other hand, argues that focusing on the possibility of decimation of unit members by sequencing the elements that make up the space smaller than the unit space is closer to an ecological architecture. Second, what Kuma Kengo says is "erase the architecture" that is naturally related to the environment and disappears when its use is exhausted. His argument is expressed in individual architectural works through 'visual erase', 'particle painting of materials' and 'independence through dependency.' Through this, Kuma Kengo's ecological architectural languages were influenced by the ecological causes of metabolism, but they differed from the perspective of seeing architectural circulation as an organism. If metabolism was intended to realize circulation with growth potential based on the module of unit space, Kuma Kengo sought to implement circulation with the extinction of the unit members of space.

  • Species are facing strong selection pressures to adapt to inhospitable high-altitude environments. Yaks are a valuable species and an iconic symbol of the Qinghai-Tibet Plateau. Extensive studies of high-altitude adaptation have been conducted, but few have focused on metabolism. In the present study, we determined the differences in the serum metabolomics between yaks and the closely related species of low-altitude yellow cattle and dairy cows. We generated high-quality metabolite profiling data for 36 samples derived from the three species, and a clear separation trend was obtained between yaks and the other animals from principal component analysis. In addition, we identified a total of 63 differentially expressed metabolites among the three species. Functional analysis revealed that differentially expressed metabolites were related to the innate immune activation, oxidative stress-related metabolism, and energy metabolism in yaks, which indicates the important roles of metabolites in high-altitude adaptation in yaks. The results provide new insights into the mechanism of adaptation or acclimatization to high-altitude environments in yaks and hypoxia-related diseases in humans.

  • This study was conducted to identify the effects of a planned exercise program based on Bandura's self efficacy model on metabolism, and the exercise compliance in type 2 diabetes mellitus patients. The study design was a nonequivalent pre-test post-test control design. Thirty four type 2 diabetes mellitus patients, who received follow-up care regularly through the diabetic out-patient clinic, were randomly sampled for this study. Twenty patients were assigned to the experimental group and fourteen patients were assigned to the control group. In the experimental group, a planned exercise program is composed of an individualized exercise prescription for 12 weeks, an individual education, and even a telephone coach program. In the case of the control group, they were instructed to continue with their usual schedules. The data collection period was from March 1999 to February 2000 Data were analyzed using SPSS/WINDOW 10.0 program. The results were as follows. 1. In the experimental group, the level of fasting blood sugar has significantly decreased from 188.20 mg/㎗ to 155.55 mg/㎗ after planned exercise program (F= 16.86, p=.000). For lipid metabolism, body fat per cutaneous decreased from 27.16% to 26.57% after planned exercise program. The score of self efficacy has increased from 64.20 to 66.65 after planned exercise program and it was statistically significant (F=4.850, p=.040) The functional vital capacity has increased from 3.28$\ell$ to 3.37$\ell$and it was statistically significant(F=7.300, p=.020). 2. In an after effect of a planned exercise program, 35 percent of the subjects who participated in a planned exercise program continued to exercise for another six months. In conclusion, the planned exercise program can improve cardiopulmonary function, glucose, and lipid metabolism. This program was show a positive effect on the self efficacy and exercise compliance.

  • The ultimate aim of this study is to find high-fiber sources among Korean common foods and to develop a high-fiber supplement which can be useful in the therapeutic diet for the diabetic patients. For this purpose the effect of four kinds of seaweeds(mixture of purple laver & sea lettuce : MPS, sea tanle : ST, sea mustard : SM, agar agar : AA) on the glucose and lipid mtabolism were examined. Seven groups of normal and streptozotocin-induced diabetic rats were fed dietary fiber-free control diet or one of experimental diets containing 7% of one of four seaweeds for six weeks. The effects of seaweeds were campared with the effects of fiber-free diet or pectin diet. ST, SM, and AA showed a tendency of improving glucose tolerance improvement by those seaweeds, however, was less than that by pectin. MPS was found to possess a serum cholesterol-lowering effect which is comparable to that of pectin. All the supplementations of seaweeds induced significant increase in fecal steroids excretion. The amounts of fecal cholesterol excretion follwing in feeding of MPS and SM were as high as the level cause by pectin. The excretion of bile acids in the MPS group was much higher than that in the pectin group. Based on its effects of alleviating the diabetic symptoms in the previous study and of improving the glucose tolerance, sea mustard seems to have a benefical effect on glucose metabolism. The serum cholesterol-lowering effect of MPS possibly due to the significant increase in fecal steroids excretion suggests that MPS may be effective in improving abnormalities of lipid metabolism. Therefore, sea tangle and mixture of purple laver & sea lettuce seem to be promising as an effective source of high-fiber supplement for the diabetic patients.

  • This study was carried out to investigate the motor activity and glucose transport and metabolism of Gaewool-Whadam-Jian(GWJ) in rat gastro-intestinal tract. The motor activity of the rat gastro-intestinal tract has been investigated by means of measuring barium sulfate passage degrees. Atropine treatment significantly delayed barium sulfate transit, and GWJ pretreatment increased intestinal motor activity, but not significant. GWJ administration showed no toxicity to kidney and liver. Transport and metabolism of glucose were studied in everted sac of rat small intestine with incubation under several conditions. The transport and metabolism of glucose were greater at jejunum than ileum. So, everted jejunum of rat were used to study the effect of GWJ. When GWJ were treated, the concentration of glucose were higher than untreated group. This result was thought to be influenced by the glucose in GWJ. When 2, 4 dinitrophenol and phlorizin were treated, the transport and metabolism of glucose were decreased, but GWJ treated together, the concentration of glucose in serosal solution increased. Gastric juice secretion and total acidity significantly decreased by administration of GWJ through duodenum region. The mechanism of effect of GWJ was still unidentified, Dut through continuous investigation, the effect of GWJ should be investigated.

  • Both hydrolysed guar gum and polydextrose have been used as a major fiber source in preparations of unctional drink products and other food products. In this study we determined the effects of these fibers on lipid metabolism of normal rats with two different dietary fat levels by using cellulose as the control. Serum total lipid triglyceride total cholesterol and HDL-colesterol were determined with proper enzymatic methods. Feed intake weight gain and feed efficiency ratio were also calcula-ted. Polydextrose-fed group showed lower serum triglyceride level than hydrolysed guar gum-fed group regardless of fat level used in this study without changing total lipid level in the serum. We also observed that polydextrose-fed group showed low serum cholesterol level nummerically high serum HDL-cholestrol level and more excretion of fecal neutral sterols when compare with those values of hydrolysed guar gum-fed group. The results indicate that polydextrose might have more beneficial roles in lipid metabolism when compare with hydrolysed guar gum.

  • Objective: As one of the most important metabolic organs, the liver plays vital roles in modulating the lipid metabolism. This study was to compare miRNA expression profiles of the Large White liver between two different developmental periods and to identify candidate miRNAs for lipid metabolism. Methods: Eight liver samples were collected from White Large of 70-day fetus (P70) and of 70-day piglets (D70) (with 4 biological repeats at each development period) to construct sRNA libraries. Then the eight prepared sRNA libraries were sequenced using Illumina next-generation sequencing technology on HiSeq 2500 platform. Results: As a result, we obtained 346 known and 187 novel miRNAs. Compared with the D70, 55 down- and 61 up-regulated miRNAs were shown to be significantly differentially expressed (DE). Gene ontology and Kyoto encyclopedia of genes and genomes enrichment analysis indicated that these DE miRNAs were mainly involved in growth, development and diverse metabolic processes. They were predicted to regulate lipid metabolism through adipocytokine signaling pathway, mitogen-activated protein kinase, AMP-activated protein kinase, cyclic adenosine monophosphate, phosphatidylinositol 3 kinase/protein kinase B, and Notch signaling pathway. The four most abundantly expressed miRNAs were miR-122, miR-26a and miR-30a-5p (miR-122 only in P70), which play important roles in lipid metabolism. Integration analysis (details of mRNAs sequencing data were shown in another unpublished paper) revealed that many target genes of the DE miRNAs (miR-181b, miR-145-5p, miR-199a-5p, and miR-98) might be critical regulators in lipid metabolic process, including acyl-CoA synthetase long chain family member 4, ATP-binding casette A4, and stearyl-CoA desaturase. Thus, these miRNAs were the promising candidates for lipid metabolism. Conclusion: Our study provides the main differences in the Large White at miRNA level between two different developmental stages. It supplies a valuable database for the further function and mechanism elucidation of miRNAs in porcine liver development and lipid metabolism.

  • Recently it is reported that RBC membrane fluidity decreases and RBC calcium levels increase with age. The aim of this study was to analyze changes in lipid and calcium metabolism with age, and to seek relationship of diet and metabolism. With clinically normal Korean adults(male 60, female 63), this study was carried out in three phases : 1) to analyze fatty acid percentage of RBC membrane, 2) to analyze calcium levels of RBC with age, and 3) to compare the effects of dietary fatty acid intake on blood fatty acid profiles. The results are as follows : The P/S ratio of RBC membrane fatty acid decreased with age. The RBC calcium content increased according to age, with women having a higher level than men. The higher intake groups of linolenic acid(C18:3) has statistically higher serum linolenic acid levels. But dietary effects of membrane fatty acid were not found. Therefore, the further research to seek the possible relationship of diet and membrane fatty acid should be continued.

  • It has been reported that sulfur-containing intermediates or products in the transsulfuration pathway including S-adenosylmethionine, 5'-methylthioadenosine, glutathione and taurine can prevent liver injury mediated by inflammation response induced by lipopolysaccharide (LPS) treatment. The present study examines the modulation of hepatic metabolism of sulfur amino acid in a model of acute sepsis induced by LPS treatment (5 mg/kg, iv). Serum TNF-alpha and hepatotoxic parameters were significantly increased in rats treated with LPS, indicating that LPS results in sepsis at the doses used in this study. LPS also induced oxidative stress determined by increases in malondialdehyde levels and decreases in total oxy-radical scavenging capacities. Hepatic methionine and glutathione concentrations were decreased, but S-adenosylho-mocysteine, cystathionine, cysteine, hypotaurine and taurine concentrations were increased. Hepatic protein expression of methionine adenosyltransferase, cystathionine beta-synthase and cysteine dioxygenase were induced, but gamma-glutamylcysteine ligase catalytic subunit levels were decreased. The results show that sepsis activates transsulfuration pathway from methionine to cysteine, suggesting an increased requirement for methionine during sepsis.
