The crystal shnture of dehydrated fully Cd2+-exchanged zeolite A evacuated at 2 × 10-6 Torr and 650℃ (a:12.189(2) A) and of its iodine sorption corrplex (a:12.168(2)A) have been netsmlmn by single uystal x-ray diffraction techliques in the cubic space group hkTn at 21(1)℃. The strutures were refined to final error indices, Ri:0.057 and R2 =0.063 with 186 reflections and Rl:0.082 and R2:0.085 with 181 reflections, respectively, for which 1>3σ(In both structure, six lie at two distinguished threefold axes of unit cell ten the crystal structure of an iodine sorption complex of Cd6-A four Cd2+ ions are recessed 0.69(1) A into the large cavity to complex each with from the (111) plane of 0(3), whereas two Cd2+ ions recessed 0.68(1) A into the sodalite unit Awximately 4.0 l3ions per nit cell are sorbed. Each bridge between a Cd2+ ion and 8-ring oxygens ((I-I-I)= 117(1) ˚ and 0(1)-I(1)-I(2)=172(1)). The near linear I-I-0 angle and its interatomic distance (I-0=3.57(3) A) are indicative of a weak charge transfer interacticn between the frarrework oxygen and iodine. The existence of In3 inside the large cavity indicates that the If ions and H ions may be produced by reaction of In vapor with water molecules which maybe associated with Cd2+ ions in partially dehydrated Cd6-A In3- ions may be produced by the combination of I- and I2.

This study aimed to confirm the potential as a material for food, medicine, and cosmetics by measuring the physiological activity of the complex extract(Leonurus japonicus Houtt., Houttuynia cordata Thunberg and Citrus unshiu Markovich). The complex extract was with hot water, The evaluation of cytotoxicity, antioxidant, anti-inflammatory, and MAPKs of the extract was performed by using ELISA and western blot. Total polyphenols and flavonoid contents of complex extracts were 126.16 mg/g and 105.84 mg/g, respectively. The scavenging activities of DPPH and ABTS radical significantly increased in a dose-dependent in complex extracts. Compared to the control group, the complex extracts treatments significantly reduced concentrations of nitric oxide and inflammatory cytokine (i.e., IL-1β, TNF-α, and IL-6). Furthermore, the complex extracts treatments significantly reduced protein expression levels of MAPKs (i.e., ERK, JNK, and p38). The results indicate that the complex extract can be used for oxidative damage and inflammation. Thus, the results of this study can be used as basic data for composite materials for food, medicine, and cosmetics.

Pseudomonas fluorescens strain CL0145A was discovered at the New York State Museum Field Research Laboratory as an effective agent against the environmentally destructive zebra mussel, which has contaminated US waters. Dried cells of the microbe are being commercialized as an environmentally friendly solution to the problem. We found that antibiotic activity against the Gram-positive bacterium Bacillus subtilis is produced and excreted by this strain. We have carried out studies to optimize production of the antibiotic. Studies were begun in a complex corn meal medium. Activity was found in both cells and culture supernates and was maximal after one day of fermentation. Static fermentation conditions were found to be superior to shaken culture. Production of extracellular antibiotic in complex medium was found to be dependent on the content of sucrose and enzyme-hydrolyzed casein. Indeed, production was greater in sucrose plus enzyme-hydrolyzed casein than in the complex medium. Of a large number of carbon sources studied as improvements over sucrose, the best was glycerol. An examination of nitrogen sources showed that production was improved by replacement of enzyme-hydrolyzed casein with soy hydrolysates. Production in the simple glycerol-Hy-Soy medium was not improved by addition of an inorganic salt mixture or by complex nitrogen sources, with the exception of malt extract. In an attempt to keep the medium more defined, we studied the effect of amino acids and vitamins as replacements for malt extract. Of 21 amino acids and 7 vitamins, we found tryptophan, glutamine, biotin, and riboflavin to be stimulatory. The final medium contained glycerol, Hy-Soy, tryptophan, glutamine, biotin, and riboflavin.

This study examines multiple functions of the complex cultural center. Recently, the importance of the complex cultural center has been growing, as peoples desire for cultural activities diversified. In order to effectively accommodate the general publics interests in various cultural activities, the complex cultural center tended to be multi-functional. At the same time, I argue that it is necessary to reexamine its functions in terms of how the multi-complex cultural center fits into local environment. Only when both peoples demand and local environment are fully integrated into its design, can the multi-complex cultural center accomplish the goal of multiple functions in a true sense.

Let M be a real hypersurface of a complex space form with constant curvature c. In this paper, we study the hypersurface M admitting Miao-Tam critical metric, i.e., the induced metric g on M satisfies the equation: $-({\Delta}_g{\lambda})g+{\nabla}^2_g{\lambda}-{\lambda}Ric=g$, where ${\lambda}$ is a smooth function on M. At first, for the case where M is Hopf, c = 0 and $c{\neq}0$ are considered respectively. For the non-Hopf case, we prove that the ruled real hypersurfaces of non-flat complex space forms do not admit Miao-Tam critical metrics. Finally, it is proved that a compact hypersurface of a complex Euclidean space admitting Miao-Tam critical metric with ${\lambda}$ > 0 or ${\lambda}$ < 0 is a sphere and a compact hypersurface of a non-flat complex space form does not exist such a critical metric.

Objectives: This report presents the case of a 21-year-old woman with lower extremity paresthesia in both feet due to polyneuropathy. Methods: The patient was treated using a Korean traditional complex treatment approach that included herbal medication, acupuncture, electroacupuncture, and moxibustion. We evaluated the improvements in the pain symptoms in both feet using the numeric rating scale (NRS); we also assessed for gait disturbance and used Digital Infrared Thermographic Imaging (D.I.T.I.) to evaluate minute changes in body temperature in diseased areas. Results: After administering the Korean traditional complex treatment, we observed a decrease in pain levels in both feet based on the NRS scores. We also observed improvements in gait disturbance and D.I.T.I. Conclusions: This case showed that the use of a Korean traditional complex treatment approach, consisting of herbal medication, acupuncture, electroacupuncture, moxibustion, had a positive effect on decreasing polyneuropathy symptoms.

An investigation of the coordination behavior of sulfur-containing mixed-donor tribenzo-macrocycles $L^1-L^3$ ($L^1$: 20-membered $O_3S_2$, $L^2$: 20-membered $O_2S_3$, and $L^3$: 23-membered $O_4S_2$) with $d^{10}$-metal ($Ag^+$, $Hg^{2+}$, and $Pb^{2+}$) salts is reported. The X-ray structures of five complexes (1-5) with different structural types and stoichiometries, including mono- to dinuclear species have been determined. Reactions of $L^2$ and $L^3$ with the silver(I) salts ($PF_6{^-}$ and $SCN^-$) afforded two dinuclear 2:2 (metal-to-ligand) complexes with different arrangements: a sandwich-type cyclic dinuclear complex $[Ag_2(L^2)_2](PF_6)_2{\cdot}3CH_2Cl_2$ (1) and a linear dinuclear complex $[Ag_2(L^3)_2(SCN)_2]$ (2), in which two monosilver(I) complex units are linked by an Ag-Ag contact. Reactions of $L^1$ and $L^2$ with mercury(II) salts ($SCN^-$ and $Cl^-$) gave a mononuclear 1:1 complexes $[Hg(L^1)(SCN)_2]$ (3) and $[Hg(L^2)Cl_2]$ (4) with anion coordination in both cases. $L^2$ reacts with lead(II) perchlorate to yield a mononuclear sandwich-type complex $[Pb(L^2)_2(ClO_4)_2]$ (5), giving an overall metal coordination geometry of eight with a square antiprism arrangement. From these results, the effects of the donor variation and the anioncoordination ability on the resulting topologies of the soft metal complexes are discussed.

Development of index for evaluation of environmental nature and its application for the purpose of construction of industrial complex with environmentally friendly. Industrial complex comes to be recognized as a disgusting zone according to the increasing environment consciousness of residents. And the objection about the exploitation of geographically unwanted land site is increased during development process and it is possible to cause Nimby phenomenon. Therefore, ecology and environment-oriented strategies tends to be adopted for industrial complex development. Furthermore, the maximization of profit mainly directed by enterprises as of today cannot guarantee its future and the efforts of adopting environmental constancy and harmony as a new objective are made progressively. For the development of city and region, in particular such as residence complex, farming and special city, the discussion of environmental consistency, new paradigm with environmentally friendly is briskly under progress, but the relevant discussion for the development of industrial estate is not done so much. Just only few studies are realized from the viewpoint of industrial ecology but its level remains in the understanding of the concepts and presentation of development direction. This study is to prepare for the foundation of the construction of industrial estate with environmentally friendly under the current condition of Korea against coming future environment era and to try to develop of evaluation range and index which are the basis of evaluation of environment. I applied the above evaluation index to the residents of actual industrial estate to understand their consciousness of decreased environment. And I obtained 7 evaluation ranges and 37 evaluation indexes for the relevant residents. Among them, I get the value less than the average in 19 index items. And they represent very sensible reaction about environment pollution including decrease of waste materials. This study has several limits but is meaningful in that the development of evaluation index for environmental nature in industrial complex is done, and that the basic discussion of the plan and design for environmentally friendly industrial estate is made under the above evaluation and that 37 evaluation items are applied to the reality.

The distribution of respiratory chain complexes in beef heart and human muscle mitochondria has been explored by immunoeledron microscopy with antibodies made against beef heart mltochondriai proteins in conjundion with protein A cofloidai gold (l2nm particles). The antibodies used were made against NADH-conezyme Q reductase(complex I), ubiquinol-cytochrome-c-oxldoreductase (complex III) and cytochrome-c-oxidase(complex IV). Labeling of bed heart tissue with any of these antihodies gave gold particles randomly distributed along the mitochondrial inner membrane. The labeling of muscle tIssue mitochondria from a patient with a mitochondrial myopathy localized by biochemical analysis to complex III was quantitated and compared with the labeling of human control muscle tissue mitochondria. Four kinds of morphological changes in the mitochondrial fine strudure in the myopathy patient tissue have been found; paracrystalline inclusions consistIng of densely packed multi- lamellar structures, globular crystalline inclusions with high electron density, multilamellar strudure inclusion body(compadly and irregularly arranged concentric whirl shaped cristae)and golbular cyrstalilne inclusions located in the center of the whirl shaped cristae. Compex I and cytochrome-c-oxldase antihodies reacted to the same level in the mitochondria containing the crystalline inclusions and control mitochondria. Antibodies to complex III reacted very poorly to the mitochondria containing the crystalline Inclusions but strongly to control mitchondria. The globular crystalline inclusions in the mitochondria are not reacted antibodies to respiratory chain complexes.
