Coarse resolution (9 - 50 km pixels) Sea Surface Temperature satellite data are frequently considered adequate for open ocean research. However, coastal regions, including coral reef, estuarine and mesoscale upwelling regions require high-resolution (1-km pixel) SST data. The AVHRR SST data often suffer from navigation errors of several kilometres and still require manual navigation adjustments. The second serious problem is faulty and ineffective cloud-detection algorithms used operationally; many of these are based on radiance thresholds and moving window tests. With these methods, increasing sensitivity leads to masking of valid pixels. These errors lead to significant cold pixel biases and hamper image compositing, anomaly detection, and time-series analysis. Here, after manual navigation of over 40,000 AVHRR images, we implemented a new cloud filter that differs from other published methods. The filter first compares a pixel value with a climatological value built from the historical database, and then tests it against a time-based median value derived for that pixel from all satellite passes collected within ${\pm}3$ days. If the difference is larger than a predefined threshold, the pixel is flagged as cloud. We tested the method and compared to in situ SST from several shallow water buoys in the Florida Keys. Cloud statistics from all satellite sensors (AVHRR, MODIS) shows that a climatology filter with a $4^{\circ}C$ threshold and a median filter threshold of $2^{\circ}C$ are effective and accurate to filter clouds without masking good data. RMS difference between concurrent in situ and satellite SST data for the shallow waters (< 10 m bottom depth) is < $1^{\circ}C$, with only a small bias. The filter has been applied to the entire series of high-resolution SST data since1993 (including MODIS SST data since 2003), and a climatology is constructed to serve as the baseline to detect anomaly events.

The main focus of this paper is to provide clear understanding about the concept of make-up as total fashion by defining the essential meaning of it. First, we would like to go over the concept of make-up and total fashion, then analyze the make-up image, the changes of colors and images of make-up overtime and fashion that have influenced over those changes. In this paper, we analyze the trend of fashion and make-up in 1990s and their relevancy. Through this paper we hope that make-up can be accepted as a part of total fashion in its relationship with other elements such as shoes, clothes and accessory and that it can be considered as a independent art that has direct influence on people. The trend of Spring/Summer between 1990 and 92is the image of natural beauty and comfortable and modernistic image that can be experienced through nature. In 1992, there was a revival look of 1960s and 1970s. Make-up also followed this trend. The overall color tone was to give natural and stable images with pastel tone to soften the images. This tone brought back the ecology of 1960s. The theme of restoration in humanity and nostalgia was reflected in clothing, and these trend changed the ecology of make-up to peace, love and romantic ecology which was expressed in coral, blue, and green tone to create intelligent image of woman. Year 1996 could be called as color revolution period that emphasized the unique and individual expression of each person. In 1997, black, pastel and brown colors were the result of reinterpreting the classic and sexy images of 1960s to natural and modernistic image of 1997. Purple color started to be introduced to us. The beginning of 1990s Fall/Winter season was based on ecology concept that emphasized the natural image. Until 1995 it appeared that spring/summer and fall/winter trend had no big differences. But from 1995 seasonal differences in trend are appeared and there were various make-up designs. In 1995, 1996, brown color lines make-up comes to mix with romantic image and developed into wine, orange, neon colors. These color were the symbol of property and sentiment and gold make-up emphasizing the eye area was the tendency of that period. In 1997, the fear of coming end of century was expressed as decadent image and at that time ethnic image, romantic image appeared with vivid color lines, gold, red and violet.

The purpose of this study was to compare effects of various bone grafts on periodontal regeneration of alveolar bone defects in dogs. Seven adult dogs aged 12 to 18 months were used in this study. Experimental alveolar bone defects were created surgically with a #1/2 round bur at the furcation area of the buccal surface of the mandibular 3rd, 4th premolars and 1st molar. Each experimental alveolar bone defects were grafted with dense hydroxyapatite, natural coral, and decalcified freeze-dried bone, and respectively divided into DHA, NC, DFDB group. An area without bone graft was divided into control group. At 1,2,4,6, and 12 weeks, dogs were serially sacrificed and specimens were prepared with Hematoxylin-Eosin stain and Mallory stain for light microscopic evaluation. The results of this study were as follows : 1. In control group, the matrix change of granulation tissue was observed at 1 week. And in experimental groups, the appearance of connective tissue around graft materials was loosely formed at 1 week, but densely formed at 2 weeks. 2. In every group, the slight formation of new trabecular bone was seen from remaining bone at 1 week. 3. The DHA and NC particles were gradually encapsulated by new trabecular bone from remaining bone, and the osteoid tissue was directly induced from DFDB particles. 4. The presence of osteoblasts was first observed at 1 week in control group and at 2 weeks in NC group, but at 6 weeks in DHA group. 5. In DHA group, the resorption of particles was not observed until 12 weeks. But in NC and DFDB group, the particles were resorbed at 6 weeks and replaced by new bone. And the amount and size of particles were reduced, and their border represented irregular form. In summary, in three experimental groups the inflammatory or foreign body reaction were slight, but the regeneration of new osteoid tissue and the matrix change of dense connective tissue fiber were observed. Especially, NC and DFDB materials were considered as the biocompatible graft materials which were effective in the regenertion of new bone.

Synthetic bone graft materials have been used for the regeneration of periodontal tissue lost due to periodontal disease, but the limitations of these materials had prompted the use of composite grafts. Among those, a composite graft of calcium carbonate(CC) and calcium sulfate(CS) is one of those materials that has not been studied extensively. CC, which is extracted from a natural coral, is known to possess osteoconductive property. SC can play an adjunctive role in the regeneration of bone tissue, and has shown good resorbability and biocompatibility. This study was conducted in order to investigate the effects of CC and CS composite graft to the regeneration of bone in the intrabony defects of dogs. 3-wall intrabony defects ub size of $4mm{\times}4mm{\times}4mm$ were created in the alveolar bone in the premolar areas. Then those defects that were treated with root planning only were designated as control, while the experimental group 1 and 2 each received the CC and CS composite grafts in the ratio of 8 : 2 and 5 : 5 the animals were sacrificed after 8weeks and the specimens were histologically analyzed. The results were as follows ; 1. No inflammation or foreign body reaction were observed in all subjects. CS has not been seen due to complete resorption, and resorption pattern of CC was observed. 2. Significant differences(p<0.05) in new cementum formation were observed between control($1.42{\pm}0.64mm$) and experimental groups(group 1 ; $2.53{\pm}0.94mm$, group 2 ; $2.23{\pm}0.96mm$) but the difference between the two experimental groups was not significant. 3. Significant differences(p<0.01) in new bone formation were observed between control($0.59{\pm}0.55mm$) and experimental groups(group 1 ; $2.27{\pm}0.61mm$, group 2 ; $2.05{\pm}0.56mm$) but the difference between the two experimental groups was not significant. 4. The extent of apical epithelial migration has shown no significant difference between control($1.18{\pm}1.24mm$) and experimental groups(group 1 ; $0.51{\pm}0.54mm$, group 2 ; $0.73{\pm}0.70mm$). 5. The extent of bone formation was generally limited to the extent of cementum formation for all groups, and significant correlation was found in the amount of bone formation and cementum formation in experimental group 1.(Co.=0.86, p<0.01) These results suggest that the composite graft of CC and CS is biocomplatible and effective in the new bone and new cementum formations. In the case of 3-wall intrabony defects of dogs, the composite ratio of 8 : 2 and 5 : 5 had shown no significant differences in the healing.

동물플랑크톤 군집생산에 주요요인인 생물량의 시간적인 양적 및 질적 차이를 찾기 위해, 1996년 9월부터 1997년 8월까지 특별히 고안된 표층 채집장치에 의해 시간별로 채집된 동물플랑크톤를 대상으로 계절별 출현개체수, 현존량의 일변동, 젤라틴성 동물플랑크톤의 습중량과 건중량의 관계 및 동물플랑크톤의 체장과 체중에 의한 크기분포 등을 조사하였다. 젤라틴성 동물플랑크톤의 건중량에 대한 습중량비(W/D)는 평균 66.46(47.05${\sim}$84.64)를 나타내고, 갑각류를 중심으로 한 일반 동물플랑크톤에서는 10.89(9.21${\sim}$14.85)로 6배 이상의 차이를 보였다. 한편 습중량에서 일반 동물플랑크톤에 대한 젤라틴성 동물플랑크톤의 평균비(G/NG)는 0.99(0.28${\sim}$2.30)로 젤라틴성 동물플랑크톤이 차지하는 비율은 매우 높았다. 이러한 값들은 계절별 일 변동폭도 매우 컸으며, 이는 구성 종의 상대 출현율의 차에 따른 것이었고, 각 그룹의 동물플랑크톤 주야수직이동의 특성과 일치하였다. 또한 체장에 의한 크기분포(250${\sim}$500 ${\mu}m$: 35.5%)와 습중량(0.I${\sim}$0.2 mg: 34.4%)과 건중량(0.025${\sim}$0.05mg: 44.8%)에 의한 크기분포 양상은 구성생물에 따라 큰 차이를 보이고 있어서, 습중량에 국한되어 조사된 대규모의 정량자료는 해역의 정확한 생물생산 추정을 통한 연안자원의 재평가를 위하여 다시 보정 ${\cdot}$ 해석되어야 할 필요성을 시사하였다.

Ornaments are accessories for the decoration of the body or dress. They aren't unavoidably required one, but serve to make one's dress perfect as decorative industrial art objects. In Morocco, ornaments were initially used as a sign of social position or the class or an incantatory symbol. In effect, they were originally employed to adjust one's dress, not just for decoration, and they were of use for household economy. Gold, silver and handcraft available for exchange were a means of increasing one's property and an indication of social standing and wealth. In particular, the dress and jewelry of a bride was a measure of her family's wealth, regarded as a symbol of her chastity and value. The ornaments symbolically back up people's faith in supernatural power, and their real value is based on implicit form or way of decoration, not the external shape. Specifically, there is a tendency to use the form of animal as a protector, not one to frighten people. In the artistic tradition of Morocco, fish pattern stands for water and rain, and eagle and bird are considered to be related to fate. Scorpion and lizard are depicted as an inquirer of sun, and snake is a symbol of abundance and sexual instinct, being viewed to have an ability to cure disease. Turtle pattern is a symbol of saint because it protects one from the evil. The ornaments are made of gold, silver, amber, clam, garnet, glass, nielle, enamel, glaze, coral or tree, and symbolic patterns are used, including hand(a symbol of five numerals), turtle, lizard, scorpion, eye, triangle, bird and eggs. They are very big and diverse, being categorized into ornaments for the head or the chest, neckless, fibula, earring, bracelet and ring. For Moroccans, make-up is a sort of instinctive behavior to meet aesthetic and sexual desire. They also wear make-up for practical purpose of protection, intentionally inflict a wound on the skin for ceremonial or religious purpose, paint the skin with pigment, or have the part of the body tattooed for incantatory purpose. All this actions are regarded as make-up. The raw material of cosmetics is aker, a vegetable dye. They get the lips or cheeks turn red and paint eyebrows with yellow saffran powder to have a bad devil lose its strength. Tattooing is mainly done by women and viewed as a sign of their value or social organization they belong to. Sometimes that is used to represent a woman's being old enough to marry or getting married already or the frequency of marriage. Besides, tattoo is believed to prevent or remedy loose bowels or cough, depending on its location or pattern, and they often change tattoo according to the change of beauty art.
