Al2TiO5 has a high refractive index and good solubility of the chromophore in the Al2TiO5 lattice, which allowsthis structure to be a good candidate for the development of new ceramic pigments. However, pure Al2TiO5 is well knownto decompose on firing at 900~1100oC. However, this process can be inhibited by the incorporation of certain metal cationsinto its crystalline lattice. In this study, the synthesis of gray ceramic pigment was performed by doping cobalt on the Al2TiO5crystal structure. The Al2TiO5 was synthesized using Al2O3 and TiO2, and doped with Co3O4 as a chromophore material. Inorder to prevent the thermal decomposition during the cooling procedure, MgO was added to samples by 0.05mole, 0.1mole,and 0.15mole as a stabilizer. The samples were fired at 1500oC for 2 hours and cooled naturally. The crystal structure, solubilitylimit, and color of the synthesized pigment were analyzed using XRD, Raman spectroscopy, UV, and UV-vis. Al2O3 wasavailable for the formation of CoAl2O4, which should also be considered in order to explain the small amount of this phasedetected in the sample with the higher Co2+ content (≥0.03mole). It was found that the solubility limit of Co2+ in the Al2TiO5crystal was 0.02mole% through an analysis of Raman spectroscopy. Through the addition of a pigment with 0.02mole% ofCo2+ to lime-barium glaze, stabilized gray color pigments with 66.54, −2.35, and 4.68 as CIE-L*a*b* were synthesized.

This study was carried out to investigate antibiotic resistances of 181 isolates in Staphylococcus aureus isolated from 450 specimens which were a General Hospital personnel in Cheonan province. Of the 181 isolates, 89 isolates (49.2%) were methicillin resistant and 92 isolates were susceptible. They were resistant to penicillin (80.1%), clindamycin (18.8%), oxacillin (49.2%), cefepime (28.2%), cefotetan (34.3%), ampicillin (66.3%), gentamicin (27.6%), tetracycline (17.7%) and erythromycine (43.1%), also. In resistant rates of the 89 MRSA, 5 antibiotics were more than 50%, but in those of the 92 MSSA, only 1 antibiotics was. Also they showed very highly multi-drug resistance patterns to 15 antibiotics as follow : One hundred and forty five isolates(82.3%) showed antibiotic resistance to more than one kind of the 15 kinds antibiotics. In the multiple resistant patterns, one drug resistant isolates were 18 isolates (9.9%), 2 drugs 29 (16.0%), 3 drugs 21 (11.6%), 4 drugs 29 (16.0%), and more than 5 drugs were 52 isolates (28.7%). The number of more than 5 drugs resistant strains in MSSA were only 1 strain, but those in MRSA were 51 isolates (57.3%). Forty five isolates (24.9%) produced enterotoxin serotype C and all MRSA.

Glutamate-induced oxidative injury contributes to neuronal degeneration in many central nervous system (CNS) diseases, such as Parkinson’s disease, Alzheimer’s disease, epilepsy and ischemia. Inducible heme oxygenase (HO)-1 acts against oxidants that are thought to play a role in the pathogenesis of these diseases. The EtOH extracts of Viola mandshurica (NNMBS274), Viola patrinii (NNMBS275) and Viola papilionacea Pursh (NNMBS276), origin plants of Violae Herba, showed the potent neuroprotective effects on glutamate-induced neurotoxicity. Among them, NNMBS275, the extract of V. patrinii possessed the protective effects against glutamate toxicity by inducing the expression of heme oxygenase (HO)-1 in the mouse hippocampal HT22 cells. These results suggest that extracts of V. patrinii could be the effective candidates for the treatment of ROS-related neurological diseases. Furthermore, it is suggested that the protective effects of V. patrinii extract due to inducing the expression of HO-1 asAs the exfoliated keratinocytes (EKs) in oral mucosa are aging and degenerating cells, of which cytoplasms are almost replaced by cross-linked keratin materials. Consequently, the EKs become apoptotic with nuclear lysis. A question is arisen what is the biological role of these EKs in oral cavity? Are they simply degrading as aging keratinocytes or do they have some essential function still remained in the exfoliated status? The buccal smear samples from ten healthy adult subjects were observed under scanning electron microscope. On the outer surface of the EKs the features of bacterial adhesion were explored. The microorganisms attached on the surface of EKs were much deformed, shrunken and teared. Only a few microorganisms were found on the EK surface, aggregated focally. The attached microorganisms were gradually fused on the cell membrane of EKs, and subsequently endocytosed. Resultantly, many round endocytotic concave cavities similar size to the cocci were remained on the surface of EKs similar to the sequels of caveolae endocytosis. These data indicate that the degenerating EKs can actively engulf microorganisms attached on their cell surface via the processes of caveolae endocytosis. Therefore, it is presumed that the oral EKs still play a role for endocytotic scavenging of oral microorganisms using the denatured cell bodies themselves, which become highly adherent to oral microorganisms and still function for caveolae endocytosis in mixed saliva environment. an antioxidant/cytoprotective target

The composition of fatty acids in bakery products from 35 bakeries in Seoul was analyzed by GCFID. The contents of crude fat in bakery products were represented 9.54-44.30% in pastries, 14.67-41.22% in cookies and 7.63-28.15% in whipped cream cakes.

The objective of this study was to investigate the extent of total sugar and sodium in 129 different kinds of bakery products, breads and cookies, sold at bakeshops in Seoul metropolitan area. The bakery products produced by bakeshops on a small scale were not applied by clauses of mandatory nutrition label for children's taste food. All types of free sugars -fructose, glucose, sucrose, lactose and maltose- were detected in breads, but only fructose and sucrose were detected in cookies. The average amount of sucrose per 100 g of breads was 6.24 g, of cookies was 30.03 g. Breads and cookies amounting to 100 g of sample contained total sugar of 11.19 g and 30.38 g, respectively. The average amounts of sodium in breads and cookies were 120.71 mg/100 g, 70.76 mg/100 g, respectively. When the contents of total sugar in breads and cookies per one serving size were compared to WHO guidelines, the percentages were 15.7% and 18.2% about recommended daily intake of total sugar of 50 g. When it come to sodium, the bakery products had range of 1.1~6.5% to 2000 mg of daily intake of sodium recommended by WHO.

The objective of this study was to examine the effect of various discontinuous Percoll washing conditions on motile sperm recovery rate and motion kinematics. Frozen semen samples from 3 bulls (0.5 ml plastic straws, 6% glycerol in egg yolk-Tris-glycerol extender) were thawed in 37℃ water bath for 1 min. After thawing, the mixed semen samples were randomly allocated to 12 treatment groups. Briefly, the spermatozoa were centrifuged for three different time lengths (10, 20, and 30 min) at two gravities (300×g and 700×g) through two concentrations of discontinuous Percoll density gradient of 1 ml 90%: 1 ml 45% Percoll and 2 ml 90%: 2 ml 45% Percoll to remove extender, debris, and dead spermatozoa. Motile sperm recovery rate and motion kinematics were evaluated by computer assisted sperm analyzer using Makler counting chamber. Sperm motility (%) and motile sperm recovery rate showed similar pattern in all treatment groups. However, sperm motility (%) and motile sperm recovery rate were highest at 700×g for 30 min through a discontionous Percoll density gradient of 1 ml 90%: 1 ml 45% Percoll. There were no significant differences in motion kinematics after various Percoll washings. These results suggest that force of centrifugation, centrifugation time, and Percoll volume significantly affect motile sperm recovery rate.

KASI and Seoul National University developed the Fast Imaging Solar Spectrograph (FISS) as one of major scientific instruments for the 1.6 m New Solar Telescope (NST) and installed it in the Coude room of the NST at Big Bear Solar Observatory (BBSO) in May, 2010. The major objective of the FISS is to study the fine-scale structures and dynamics of plasma in the photosphere and chromosphere. To achieve it, the FISS is required to take data with a spectral resolution higher than 105 at the spectrograph mode and a temporal resolution less than 10 seconds at the imaging mode. The FISS is a spectrograph using Echelle grating and has characteristics that can observe dual bands (Hα and CaII 8542) simultaneously and perform fast imaging using fast raster scan and two fast CCD cameras. In this paper, we introduce briefly the whole process of FISS development from the requirement analysis to the first observations.

The incidence of multidrug-resistant strains of Staphylococcus aureus continues to increase in hospitals and the community all over the world. As the importance of miner surgery in dentistry gets greater recently, the frequency in use of antibiotics has been increasing. Although several cases of acquired infection in oral cavity in dental hospital has been reported, the research on isolation of S. aureus and evaluation of its antibiotic resistance from outpatients in the dental clinic has not been found yet. The aim of this study was to evaluate the antimicrobial resistance of S. aureus isolates. The isolation rate of S. aureus were 41.7% in dental hospital personnel, 60.4% in outpatients and 62% in dental hygiene students. S. aureus which showed resistance to penicillin were 88.6%, ampicillin 88.6%, erythromycin 8.6%, tetracycline 4.3%, oxacillin 4.3%, cefoteten 4.3%. Six strains of S. aureus showed the susceptible to all antibiotics tested. Sixty-four(91.4%) strains were multiple antibiotic resistance. Fifty-two strains(72.8%) resisted to AM-P. and Seven strains(10.0%) resisted to AM-P-E, AM-P-GM, AM-P-TE.

In the previous molecular cloning study from human salivary gland cDNA library novel clones (C75‐014, C76‐022) were known as candidate genes for proline rich proteins by GenBank data base search and RNA in situ hybridization. C75‐014 and C76‐022 genes were characterized as those expressing excretory basic proteins primarily composed of alanine, proline, and leucine residues, mimicking basic proline‐rich proteins (bPRPs) with helical structures and multiple consensus sequences of phosphorylation sites. In the immunohistochemical stainings using polyclonal antisera against each C75‐014 and C76‐022 peptide showed strong reaction in the secretory granules of striated and excretory ducts. And in Western blot for the different salivary specimens relatively distinctive bands appeared at lower molecular weight, ranging about 15‐50 kDa. This study was aimed to identify the molecular characteristics of C75‐014 and C76‐022 proteins, which showed properties of basic proline rich protein. These data suggest that C75‐014 and C76‐022 are candidate genes for proline rich proteins in human salivary gland, which may play a role for protecting and stabilizing the mucosal epithelium against numerous proteolytic damages and stresses.

A 37 years old male patient had suffered from fibrous nasal polyp for more than 10 years even though careful medical treatment, and recently aggravated with severe nasal stiffness and pain. In the radiological observation the lesion was continuously extended into the ipsilateral maxillary sinus by poly cystic radiopacities gradually destroying the anterior wall of antrum. During the Caldwell-Luc operation a cystic fibrous granulomatous tissue was removed, and its microsections showed multicystic and tunnel-like spaces, of which lumens were usually round and filled with parts of parasitic worm e xhibiting parasitic t eguments and eggs. The granulomatous l esion showed relatively mild inflammatory reaction with the infiltration of eosinophilic PMNs. The histological features of tunnel-like penetration of parasitic worms, and their teguments and eggs were competent with the diagnosis of sparganosis. Especially, although the patient had no experience of raw foods such as frog or snake, he used to drink the untreated natural stream water obtained in the mountain area of Gangwon prefecture in Korea. Therefore, the present study demonstrated a rare lesion of antral spanganosis, and we suppose that the frequent incident of oral sparganosis in Gangwon prefecture is possibly related to the usage of untreated stream water in the mountain area of Gangwon prefecture in Korea

In the previous molecular cloning study from human salivary gland cDNA l ibrary a novel clone (C77-091) was known as a candidate gene for antimicrobial protein by GenBank database search and RNA in situ hybridization. This study is aimed to identify the molecular characteristics of C77-091 protein, which showed an antimicrobial activity on E.coli, thereby named as salivary antimicrobial protein (SAMP). SAMP consisted of a typical hydrophobic amino acid rich domain in the N-terminus, a cluster of basic amino acids, carbohydrate attachment site, a possible transglutaminase catalyzed cross-linking site, and multiple consensus sequences of phosphorylation site in the C-terminus. Western blot analysis of human organs and tissue with the monospecific antibody to the synthetic SAMP peptide showed strong interacting protein from the extracts from submandibular gland and parotid saliva but absent in the mixed saliva, and the immunohistochemical staining detected a strong positive regions in the secretory granules in the luminal cytoplasm of interlobular ductal cells of salivary gland. The SAMP was also distributed in the human sebaceous gland and prostate. These data suggest that C77-091 named SAMP gene is a novel antimicrobial protein in human salivary gland, which may play a role for the innate immunity by protecting and stabilizing the mucosal epithelium to maintain homeostasis of oral mucosa.

Nowadays, personal media is a new tool for communication as digital cameras and mobile phones are developing rapidly. We are concerned over Cyworld users who could have different personal characteristics which will influence on buying patterns in on line shopping behaviors. The purpose of this research was to observe fashion attitudes and purchase behavior of Cyworld mini homepage users, for establishing marketing strategies by understanding consumers. For this study, one line survey was used for 500 male and female subjects who are 20 to 40 years old. Only reliable 441 questionnaires were used for analysis. The SPSS program was used for frequency, K-means cluster, t test, and chi-square test. A total of 441 respondents were clustered on the basis of 8 item self-disclosure scale, using the K-means procedures. The results indicated that respondents were clustered into two segments; 267 respondents(active attitude towards self-disclosure) and 164 ones(not active). We examined fashion attitudes in mini home page and buying behavior by self-disclosed variable. Those who are involved actively in self expression and self-disclosure considered more fashion style and trend. The major motivates of web surfing was finding a good design, and good price. High self-disclosure group tends to search many shopping mall for right design and low self disclosure group tends to search them for the right price. High self-disclosure group tend to shop the fashion products more, while low self disclosure group tend to purchase books more through the internet. We realized that active group in self-disclosure purchased their clothing accidently when they visit Cyworld.

The objective of this study was to investigate the effect of storage time on fresh boar semen in Androhep and Beltsville Thawing Solution (BTS). Boar semen samples extended in each extender were stored at 17℃ up to 4 days. Sperm motility kinematics was evaluated by computer assisted sperm analyzer (CASA) and capacitation status by chlortetracycline (CTC)/Hoechst 33258 staining. Sperm motility (%) was not decreased during storage in BTS and Androhep. No significant difference between extenders was observed. Only significant differences in kinematic parameters on linearity during storage were found. The percentage of dead sperm significantly decreased during storage (p<0.05). Also the percentage of noncapacitated, capacitated, and acrosome-reacted sperm significantly modified during storage (p<0.05). However, there was no significant difference between extenders except proportion of capacitated sperm. This finding supported that modification in these parameters was not significantly different between extenders during this short-term storage. Our finding strongly indicated that both Androhep and BTS maintained favorable conditions for motility, motility kinematics, and capacitation status during short-term storage. Despite modifications in some parameters were apparent during sperm storage in extenders, these may not affect the fertilizing capacity of boar semen.
