We have made an improved catalog of O-rich AGB stars in our Galaxy from the sources listed in the Infrared Astronomical Satellite (IRAS) point source catalog (PSC). We compile the lists of previous works with various verifying processes. We have removed 115 stars from the previous catalog of Suh & Kwon (2009) and added 958 more stars. The improved catalog contains 3036 O-rich AGB stars. The content of the revised catalog can be divided into 3 groups based on the verifying processes: OH/IR stars, SiO maser stars, and other detecting methods. We compare the new catalog with the previous catalog on the infrared two-color diagrams for the large sample of O-rich AGB stars. And we discuss differences among the 3 groups of the improved catalog and identification processes of some stars in exceptive cases.

The study was carried out to investigate for the property of Bacillus strains, on the native growthed microflora in Korean native soybean paste, and Bacillus strains of the high enzyme producing, were selected and identificated, from the microflora, that is, identificated Bacillus strains beared resemblance to B. subtills, on the colony, appearance was pellicle, surface's spreading, color creamy-thin browned, colony elevation flated, and edge lobated, the identfficated B. subtills strain named for the B. subtilis SCF. For the protease activity of B. subtilis SCF, according to the variation with pH, the pH stability was pH 7~8, and on the its protease activity, optimum temperature was 40$\circ$C, on the other hand, temperature of the highest stability of the protease was 50$\circ$C.

This study was carried to a textile conservation process included washing effect fiber analysis such as fiber identification fabric density and thickness color fading and of extracted soils. the following results were obtained. 1. AS a result of investigating to fabric surfaces by S.E.M all of cleaning methods wet cleaning-solvent cleaning in charge system were effective to remove soils from fabrics. 2. The buried fabrics were made of silk few of them were cotton ramie and hemp. 3. According to fabric density and thickness used fabrics were almost medium weight fabrics. 4. Low values of L, a, b indicated that the colors of these fabrics were faded to yellow and brown. 5. The soil components were hydrocarbon-alkane group alkyl alcohol and ketone group.

Nowadays, eyes detection is required and considered as the most important step in several applications, such as eye tracking, face identification and recognition, facial expression analysis and iris detection. This paper presents the eyes detection in facial images using Harris corner detection. Firstly, Haar-like features for face detection is used to detect a face region in an image. To separate the region of the eyes from a whole face region, the projection function is applied in this paper. At the last step, Harris corner detection is used to detect the eyes location. In experimental results, the eyes location on both grayscale and color facial images were detected accurately and effectively.

The purpose of paper is to examine about Street Furniture in swimming beach. The beach space is the very important place not only to spend in season but also to use 4-seasons in leisure culture. To offer better landscape in spacial beach; Gyeongpo, Naksan, Mangsang, Samcheok and Sokcho, such as regional atmosphere and identification are to analyze with design criteria. For the amenity of users through the improvement of landscape may be possible to work out future of beach surroundings. Accordingly material, form and color can be estimated systematically. This research suggests that design of street furniture is to be environmental and regional control. As a result, some proposal of Street Furniture by analysis, designer and officer have to focus on establishing a comprehensive plan for the attractive beach space.

Previously developed methods for pitch modification have not been based on the voice source model. Therefore, the synthesized speech often sounds unnatural although it may be highly intelligible. The purpose of this paper is to analyze the alteration of a voice source signal with pitch period and to establish the pitch-modification rule based on the result of this analysis. We examine the alteration of the interval of closing phase, closed phase and open phase using the excitation waveform as the pitch increases. In comparison to the previous methods which performed directly on the speech signal, the pitch modification method based on a voice source model shows high intelligibility and naturalness. This study might benefit the application to the speaker identification and the voice color conversion. Therefore the proposed method will provide high quality synthetic speech.

A total of 36 species and 11 genera of the fly family Lauxanidae have been previously recorded in Korean Peninsula. As a result of our ongoing study of this family, we here report the following nine species new to Korea: Homoneura albomarginata Czerny, 1932, Minettia filia (Becker), 1895, Pachycerina alutacea Shatalkin, 1998, Poecilolycia zherichini Shatalkin, 2000, Protrigonometopus sexlituris (Shatalkin), 1992, Salebrifacies czurkini Shatalkin, 1992, Sapromyza albiceps Fallén, 1820, Steganopsis dichroa Shatalkin, 1998, and Trigonometopus eborifacies Shatalkin, 1997. The genera Poecilolycia Shewell, 1986, Salebrifacies Shatalkin, 1992, and Steganopsis de Meijere, 1910 are recognized for the first time in this country. Therefore, 45 species in 14 genera are now officially recognized for the Korean lauxaniid fauna. In addition, we provide diagnoses and color photographs of adult external structures including male genitalia to aid their specific identification.

In Korean Peninsula, a total of 175 syrphid species are currently known. As a result of ongoing systematic study of the family Syrphidae, we have discovered the following five species for the first time in the Korean Peninsula: Mallota rossica Portschinsky, 1877, M. shatalkini Mutin, 1999, Sphiximorpha rachmaninovi (Violovitsh, 1981), Volucella bivitta Huo et al., 2007, and V. inanoides Hervé-Bazin, 1923. Among these taxa, Sphiximorpha Rondani, 1850, is the genus recorded for the first time in Korea. In total, three subfamilies, 16 tribes, 70 genera, and 180 species are now officially recognized for the Korean syrphid fauna. In order to facilitate their identification, we here provide specific diagnoses and color photographs for the species listed.

S-Benzylthiuronium chloride reacts with ethylene glycol, derived from hydrolysis of the fluorides, to produce a crystalline substances. Using this, the fluorides can be indentified by measuring melting point. And when the zirconium-alizarin solution reacts with ethylenefluoro hydrin or ${\beta}-fluoroethyl$ acetate, the red-violet color disappears to produce a yellow dye, which exhibits absorption maximum at about $530\;m{\mu}$ using the 250-microgram standard. Using these properties, the fluorine compounds can be determined conveniently by this method.

Phenotypes of panicle, hull and seed of mutant rice (Oryza sativa L.) were characterized. Panicle mutants were classified in 4 groups with their internode length of main rachis, primary rachis, secondary rachis and pedicel. Hull and seed mutants were grouped into 12 based on their mutant characters in shape, size and color of seeds. These natural and spontaneous mutant collections showed distinct phenotypes to wild type rice. This might be useful for the identification of the functions of genetic factors in the Mendelian inheritance.
