  • TEN-STORIED STONE PAGODA ON THE SITE OFWON-GAKSA(Temple) which is one of three marble pagodas in South Korea, were dated from the thirteenth year of the reign of King Sejo(1467). On the roof and surface of each the stories, there were large amount of the contaminants such as pigeon′s excretions, dust and environmental elements for a long time. The pH of contaminants is not acid, but is 7.2, neutral. To find the species of organic acidscontained in the contaminants and the degree of damaging for a marble pagoda, we analyzed the contaminants using GC-MSD method by the following procedures. Organic acids were extracted by saponifying whole contaminants. After Saponification, the organic acids were mathylated to increase their volatility upon subsequent GC-MSD analysis. The mathyl esters of the organic acids are extracted from the acidified aqueous solution. And the organic extracts were washed with adilute base solution. The washed extract were analyzed by GC(Hewlett Packard 5890)with a nonpolar capillary column(Crosslinked 5% Ph Me Silicone, $50×0.2㎜×0.33\mum$film thickness, USA) and Mass Spectrometric Detector(Hewlett Packard 5970B).As the result, it was found that 12 organic acids were the main compound in pagoda′contaminants, and the amount of organic acid were negligible.

  • Xuan Thuy and Con Dao are natural Ramsar sites in Vietnam with different ecosystems, geography and topography. Avian fauna in these two Ramsar sites were recorded over a 2-year period from 2018 to 2019. A total of 234 bird species belonging to 57 families and 16 orders were confirmed in Xuan Thuy, while only 71 species involving 32 families and 12 orders were found in Con Dao. In total, 25 endangered species have been found in these two national parks based on the IUCN Red List. The Spoon-billed Sandpiper and Baer's Pochard are the most endangered species ranked as Critically Endangered, whereas Nicobar pigeon, which is endemic to Con Dao, is the only endangered bird species here. This study provides the list of bird species of international importance identified in these two wetlands.

  • Over 40 per cent Indian population needs to be attended for nutritional improvement. Traditional nutritious food resources though abundantly available but presently less used, if incorporated in the diets, can yield low-cost nutritionally balanced diets. The linear programming (LP)model was used for optimization of food resources to satisfy protein -energy requirements of hard working rural poor. Soybean-a highly nutritious food legume-available at reasonably low price was included along with chick -pea and pigeon -pea for comparison .The three cereals predominantly used in Indian diets -rice, wheat and sorghum -and three typical leafy vegetables namely, spinach , drumstick leaves and rajagira (Amaranths paniculantus) leaves were used for optimization . The contribution of food legume was restricted to supply only 50 per cent of daily protein requirement for maximum protein value. The quantities of other food stuffs namely , milk , sugar , tubers etc. were restricted to nati nal per capita availability. the nutrition satisfaction levels in per cent RDA by the model are 149-250 for protein , 51-106 for fat, 134-362 for iron an d143-1158 for Vitamin-A. Quantities of food legumes, cereals and leafy vegetables ranged from 289-601, 3000-3700 and 360-1200 g/day respectively for a reference family of five hard working rural poor. Daily food resources cost ranged from US$ 0.6 to 1.0 for the family. Amongst food legumes, soybean based diet combinations provide maximum nutritional benefits at minimum cost indicating its suitability for wider adoption by hard working poor.

  • This article examined the different types of Jeonuhwa as recorded in 16 royal palace studies from the Joseon dynasty (1392-1909). The ingredients used in Jeonuhwa during the Joseon dynasty were categorized as follows: 16.0% for gray mullet(秀魚) and fish(生鮮), 14.2% each for liver and cow stomach, 12.3% for sea cucumber(海蔘), 4.7% each for crab(蟹), clam(生蛤), and chunyup(千葉), 3.9% each for pork meat(豬肉), octopus, 2.8% each for oyster(石花), pheasant(生雉), and chicken(鷄), 2.0% each for croaker(民魚), and brain (骨), 0.9% each for duck(鴨子), pigeon(山鳩), dobi(都飛), snapper, white fish(白魚), mussel(紅蛤), haeran(蟹卵), quail(鶉鳥), egg(鷄卵), and sesame(實荏子). This observation may be associated with commercial industrial development that prevailed during the late Joseon dynasty. Further studies will be conducted on recipes and ingredients recorded in Euigwe in order to develop a standardized recipe for Jeonuhwa.

  • Patterns in clothing symbolize some specific meaning that differs across cultures and religions, although patterns have been mostly used to realize human desires to overcome natural hazards in every culture or religion. This research aims to compare animal patterns of Korea (Confucian/Buddhism culture) with those of Byzantine (Christian culture), based upon a research method of literature survey. It is found through the research that both cultures used common patterns, such as dragon, butterfly, bat, honeybee, peacock, fish, and chicken. In the case of dragon patterns, Korea used it to symbolize emperor, dignity, or authority, while Byzantine used it for devil. Bat patterns had different symbolic meanings in both cultures: they mean happiness, longevity, prosperity or many off-springs in Korea while they mean misfortune or unhappiness in Byzantine. On the other hand, the rest of animal patterns, including butterfly, honeybee, peacock, chicken, had quite a similar symbolic meaning. Butterfly means change of life or beginning of new life in Korea, whereas it means resurrection in Byzantine. Honeybee symbolizes diligence, order, and cooperation. Many animal patterns were used in both cultures at the same time. Another difference can be found in terms of the kind of animals; for example, Korea used wild goose, pheasant, giraffe, deer, mandarin duck & turtle, while Byzantine used eagle, snake, pigeon. Of course, each and every animal has its own meaning, mostly positive. Except dragons and bats, both cultures have a similar meaning in most of animal patterns. Generally speaking, Korea used imaginary animals to pray for human happiness, but Byzantine used real animals to pray for resurrections.

  • The LDH isozymes are key catalysts in the glycolytic pathway of energy metabolism. It is well known that the distribution of the LDH isozymes vary in accordance with the metabolic requirements of different tissues. The substrates required for energy production change noticeably at successive stages of testes development suggesting a significant flexibility in the expression of glycolytic enzymes. Therefore, expression of LHDA and LDHB mRNAs was examined in adult and prepubertal quail testis. The mRNA of both LDHA and LDHB were expressed and no significant difference was observed in prepubertal testes. The mRNA levels of LDHB significantly increased during testicular development. In the adult testis, LDHA mRNA was not expressed. Expression studies revealed the presence of different LDH isozymes during testicular development. In contrast, electrophoresis of both testicular samples revealed only single band at a position indicative of an extreme type of LDH isozyme in quail testes. Furthermore, nucleotide and amino acid sequence analysis revealed significant similarity to chicken, duck and rock pigeon. These sequence results confirmed the similarity of LDHA and LDHB subunit protein in different avian species.

  • Environmental specimen banks provide the baselines for the scientists and decision makers to do research using the past and present specimens to expect the possible contaminant implications of the future. Many chemicals that are considered harmless now but not found may be found and pose threats in the future. Collected specimens of animals and plants should be conserved without contamination for future analysis. To ensure the availability of samples for the retrospective analysis, the establishment and maintenance of specimen banks in the developing and developed nations has become absolutely necessary. National Environmental Specimen Bank (NESB) established at National Institute of Environmental Research (NIER) in 2009. For the application of NESB, several activities such as standard operating procedures (SOPs) development have been prepared. This study applied the guidelines for sampling and sample treatment of five environmental specimens which had been prepared from 2007 to 2009. The target species were shoots of red pine and Korean pine, leaves of Mongolian oak, eggs of domestic pigeon and muscles and livers of common carp. The NESB will enhance the quality of environmental assessment and environmental monitoring based on real time and retrospective analysis.

  • A total of 166 strains of Salmonella (S) typhimurium var copenhagen isolated from pigeons (164 strains) and aquatic birds (2 strains) were examined for the biochemical characteristics and plasmid profiles. All the strains were sensitive to ampicillin, chloramphenicol, gentamicin, kanamycin and sulfadimethoxine. But 13 strains(7.8%) were resistant to streptomycin (Sm), 2 (1.2%) to tetracycline, 2 (1.2%) to rifampicin, and 1 (0.6%) to nalidixic acid. Among drug resistant strains, only one strain resistant to Sm contained conjugative R plasmid which was fertility inhibition and incompatibility group $I_{\alpha}$. All the strains were sensitive to cobalt chloride, cupric sulfate, lead nitrate, mercuric chloride and silver nitrate. Of 166 isolates, 6 (3.6%) were resistant to sodium arsenate and 1 (0.6%) to potassium tellurite. Among 166 isolates, 1 (0.6%) was colicinogenic, 12 (7.2%) sucrose fermenters, and 166 (100%) maltose fermenters. Plasmid profiles were confirmed as being 4 or 5 plasmids, and their molecular weight ranged 3.2 to 60 megadalton (MD). All the strains harbored 60 Md plasmid. There are three patterns by the plasmid profile, 150 isolates (90.4%) were pattern I (3.2, 3.5, 33, 60Md), 14 (8.4%) pattern II (3.2, 3.5, 29, 60Md), and 2 (1.2%) pattern III (4.2, 7.8, 8.5, 15, 60Md). S typhimurium var copenhagen strains containing 60Md plasmid were resistant to killing by 90% normal guinea pig serum.

  • In the ENT fields, epidermoid cysts occur infrequently in the oral region and often situated on the floor of the mouth or the submental region. Moreover, epidermoid cyst on the laryngeal surface of the epiglottis occurs rarely. Authors experienced a case of epiglottic epidermoid cyst and treated successfully by transhyoid pharyngotomy approach and marsupialization. It was 46 years old male patient who has been suffered from intermittent sorethroat for 2 years prior to admission, hoarseness for 2 months and dyspnea for 1 month. Indirect laryngoscopy revealed a pigeon egg-sized, round, smooth tumor mass on the laryngeal surface of the epiglottis which had soft consistency on digital examination. Biopsy proved epidermoid cyst. Marsupialization of the cyst by transhyoid pharyngotomy approach was performed and the postoperative course was uneventful.

  • To monitor the heavy metal exposure conditions of Feral Pigeons Columba livia, we collected them at commercial area, industrial area, park area and resident area in Seoul. In feathers, iron concentrations were significantly different among habitats(ANOVA, p<0.05), and were the highest at park area. Manganese concentrations were relatively higher at industrial and park area than other areas(ANOVA, p<0.05). In case of copper levels were the significantly highest at park area(ANOVA, p<0.05). Zinc, lead and cadmium had no difference among habitats. Correlation between livers and feathers concentrations were highly significant to copper(r²=0.983, p<0.01) and cadmium(r²=0.632, p<0.01), but iron, zinc, manganese and lead were not significantly different.
