This study was carried out to obtain the basic information for breeding of aromatic burley tobacco, and to select the breeding lines with higher DVT (diterpenes $\alpha$-and $\beta$-4, 8, 13-duvatriene-1, 3-diols) and cis-abienol (Z-labda-12, 14-diene-8$\alpha$-ol) concentrations. The parental genotypes used to develop the Fl and Fl generations were Burley 21, Ky 17, male-sterile(MS) NC 107, TC 612, TC 613, Va 509 and Tl 1068. To estimated the modes of inheritances of DVT and cis-abienol known as the flavor and aroma compounds, the method of thin - layer chromatography (TLC) was used. It was considered that TLC procedure being relatively simple and reproducible in the selection of the breeding lines with higher DVT and cis-abienol. DVT was present in all of parents except MS NC 107, but cia-abienol presented only in Tl 1068. It was estimated from the TLC analysis of parents and Fl's that DVT and cis-abienol were each inherited by dominant gene or genes. But it was less clear to determine the presence or not of sucrose ester(SE) on the TLC plate. The eleven plants which had burley leaf color and also estimated to have DVT and cis-abienol were selected in the F2 population of three combinations.

Since public rental housings (social housings) in Korea are extremely standardized and uniformed, a variety of needs of residents for their housing are hardly satisfied. Public rental housing conditions, its low quality and size limitations regardless of residents type and needs resulted into negative images of social housing and social discriminations. Therefore there is a growing demand for alternative housing options in terms of diversification of social housing design with consideration for changing households and housing requirements. The purpose of this study to investigate some housing design guidelines, to analyze layout of building complex, community designs, household units and characteristics, overall design characteristics (sustainable design features, facade design, window and balcony composition, color and materials) and to provide some design suggestions for social housing. Design guidelines are classified into site planning and building layouts, residential building and household units, and performance of housing. Community facilities and their design features provide uniqueness of the public residence. Overall housing size of foreign cases is bigger than the domestic cases. Narrow shape of household units are more dominant in Korean public rental housing. More various shape and forms are found in facade and window design in foreign cases. Some design suggestion are provided for more diverse housing units and design for public rental housing in Korea.

The purpose of this study is to examine various Oriental Medical approaches to uterine myoma treatments which have been previously proposed, and find out an appropriate method with the verification of its clinical acceptance. The treatment with GGT(Gami-gwichulikyeong-tang) and JGD (Jagungdan) has been applied to uterine myoma patients visiting Sangdang Oriental medical clinic. After the treatment, 81 cases showing significant results are selected and analyzed in terms of patients' age, social environment, previous history of treatment, condition of uterine myoma, chief complaint, and the comparison between menstrual phases before the treatment and those after it. As for the size change, no-change is dominant. For the change chief complaint take a favorable turn is better after the treatment. Color of menstruation, pathologic blood drainage, hypermenorrhea or menorrhagia. dysmentorrhea show high percentage of improvement. The results above show GGT and JGD are effective treatments for uterine myoma patients. These two are also similar to the typical prescription of Jingga, which is Gwichulpajing-tang. Thus GGT and JGD are effective to the treatment for Jingga and Jingga is one of the most valid Oriental Medical approaches to uterine myoma.

Existing image search systems allow users to search images by keywords, or by example images through content-based image retrieval (CBIR). On the other hand, users might learn more relevant textual information about an image from its text captions or surrounding contexts within documents or Web pages. Without such contexts, it's difficult to extract semantic description directly from the image content. In this paper, we propose an annotation watermarking system for users to embed text descriptions, and retrieve more relevant textual information from similar images. First, tags associated with an image are converted by two-dimensional code and embedded into the image by discrete wavelet transform (DWT). Next, for images without annotations, similar images can be obtained by CBIR techniques and embedded annotations can be extracted. Specifically, we use global features such as color ratios and dominant sub-image colors for preliminary filtering. Then, local features such as Scale-Invariant Feature Transform (SIFT) descriptors are extracted for similarity matching. This design can achieve good effectiveness with reasonable processing time in practical systems. Our experimental results showed good accuracy in retrieving similar images and extracting relevant tags from similar images.

최근 디지털카메라와 스마트 폰 등의 모바일 기기가 급속도로 발전 하면서 언제, 어디서나 손쉽게 사진을 찍을 수 있게 되었다. 이런 환경의 변화는 수없이 많은 사진을 양산하게 되었고, 손쉽게 많이 찍은 사진에 대한 분류에 불필요한 시간을 많이 보내게 되었다. 따라서 보다 편리하게 촬영된 사진들을 분류 관리하기에 적합한 자동화된 프로그램이 필요하게 되었다. 이 논문에서는 GPS나 시간 등의 메타 정보에 의존하지 않고 오직 사진의 주 색상을 이용한 히스토그램 특징과 Mean Shift 분류기를 사용하여 대략적인 분류를 시도하려했다. 실험결과를 토대로 살펴보면, 제안된 방법은 사진의 주 색상이 확실한 경우는 잘 분류할 수 있지만 여러 가지 색상이 복잡하게 혼합된 경우와 주 색상을 찾기 어려운 경우에는 분류에 한계가 있음을 알 수 있었다. 따라서 제안된 알고리즘은 사진과 영상들을 개략적인 분류를 실시할 때 주 색상 히스토그램특징이 의미 있는 전역적 특징(Global Feature)중의 하나로 생각된다.

Galaxy clusters contain a diffuse component of stars outside galaxies, that is observed as intracluster light (ICL). Since the ICL abundance increases during various dynamical exchanges of galaxies, the amount of ICL can act as a measurement tool for the dynamical stage of galaxy clusters. There are two prominent ICL formation scenarios; one is related to the brightest cluster galaxy (BCG) major mergers, and the other to the tidal stripping of galaxies. However, it is still under debate as to which is the main ICL formation mechanism. In this study we improve on earlier observational constraints of the ICL origin, by investigating it in a massive fossil cluster at z~0.47. Fossil clusters are believed to be dynamically matured galaxy clusters which have dominant BCGs. Recent simulation studies imply that, BCGs have assembled 85~90% of their mass by z~0.4 (e.g., Contini et al. 2014). Thus our target is an optimal test bed to examine the BCG-related scenario. Our deep images and Multi-Object Spectroscopic observations of the target fossil cluster (Gemini North 2018A) allow us to extract the ICL distribution, ICL color map and ICL fraction to cluster light. We will present a possible constraint of the ICL origin and discuss its connection to the BCG and the host galaxy cluster.

Granitic regolith profile in Goseong, southern Korea, reveals various types of corestones from unweathered round fresh rocks to decomposed rock cores with unweathered spheroidal rock-layers on outer surface, deep weathering profile with 10m in depth, and red saprolite usually cited as related to high temperature climatic environment. In respect of this optical features such as the depth and the color of the profile, Goseong granitic profile may be regarded as products of paleoclimate with more high temperature and humidity than the present. But it is revealed that halloysite is a predominant clay mineral in upper part as well as lower part by XRD analysis. Halloysite is dominant mineral in hydrothermal alteration milieu. The leaching rate of chemical components is up to 97%, very high compared to common granite profiles with 60~70% in Korean peninsula. So, it is assumed that granitic red regolith in Goseong is a product of hydrothermal alteration, not meteoric weathering.

Kuflu cheese, a popular variety of traditional Turkish mold-ripened cheeses, is characterized by its semi-hard texture and blue-green color. It is important to elucidate the microbiota of Kuflu cheese produced from raw milk to standardize and sustain its sensory properties. This study aimed to examine the bacteria, yeasts, and filamentous mold communities in Kuflu cheese using high-throughput amplicon sequencing based on 16S and ITS2 regions. Lactococcus, Streptococcus, and Staphylococcus were the most dominant bacterial genera while Bifidobacterium genus was found to be remarkably high in some Kuflu cheese samples. Penicillium genus dominated the filamentous mold biota while the yeasts with the highest relative abundances were detected as Debaryomyces, Pichia, and Candida. The genera Virgibacillus and Paraliobacillus, which were not previously reported for mold-ripened cheeses, were detected at high relative abundances in some Kuflu cheese samples. None of the genera that include important food pathogens like Salmonella, Campylobacter, Listeria were detected in the samples. This is the first experiment in which the microbiota of Kuflu cheeses were evaluated with a metagenomic approach. This study provided an opportunity to evaluate Kuflu cheese, which was previously examined for fungal composition, in terms of both pathogenic and beneficial bacteria.

62 specimens of deteriorated rice which were collected all over Korea, were classified according to their color outlooks, and the causitive microorganisms were isolated and identified. The following results were observed; 1. 62 specimens of deteriorated rice were classified according to color outlooks into 7 types; reddish yellow, light reddish yellow, light gray yellow, light reddish yellow, light gray yellow, light red, ligt gray, dark gray and rice weevil type. 2. The isolated microorganisms from 62 specimens of deteriorated rice were 44 species, 5 genera of molds, 1 species of yeast, and 14 species, 4 genera of bacteria. 3. The frequently observed microorganisms which caused the deterioration were Asp. glaucus group, Asp. oryzae, Asp. candidus, and Asp. versicolor. Among bacteria, Bacillus was dominant. 4. The relationship between color outlook types and the deterioration causing microrrganisms was not definite, but Pen. islandicum from reddish yellow, Asp. candidus and Asp. clavatus from light reddish yellow, Asp. glaucus group, Asp. candidus, Asp. versicolor and Asp. fumigatus from light red, Asp. oryzae from light gray yellow, and Asp. glaucus group and Pencillium species from light gray and dark gray were chiefly isolated. 5. As mycotoxin producing fungi, Asp. fumigatus, Pen. citrinum, Pen. islandicum, Asp. flavus, and Asp. ochraceus were detected, but their growth frequencies were not very high to be problems except Pen, islandicum which infected an imported rice sample heavily.

The MC1R (Melanocortin 1 receptor) gene has been known as a causative gene of the coat colors in mammals and responsible for the E (Extension) locus which has three alleles ($E^D$, $E^+$, e) that determines coat colors. The dominant allele $E^D$ produces black or brown colors due to the missense mutation and the recessive e allele has frameshift mutation which shows red or yellow coat colors. Whereas the wild type $E^+$ produces variety of colors due to the interaction with A (Agouti) locus. In this study, PCR-RFLP was performed using two restriction enzymes (BsrF I and MspA1 I) in order to obtain MC1R genotypes in Korean brindle cattle and black cattle. The results showed that all of the animals have the $E^+$ alleles, indicating the $E^+$ allele might related with black coat colors. Later on, the experiments expanded to the 260 Korean candidate bulls whether these animals have the same $E^+$ allele. Among 260 samples investigated, 5% (13/260) of the animals had $E^+$e genotypes, indicating the $E^+$ allele is also present in the candidate bulls in a low frequency. Even though we expected that A locus also affect the black coat color in cattle, all the black coat color animals (brindle and black) have $E^+$ alleles in this study. Therefore, the genotyping of the MC1R gene in candidate bulls will recommended be applied for eliminating of black coat colors in Hanwoo population, if the farmers need to have the brown coat colors only.
