Culinary herbs and spices have received much attention since they contain high concentrations of bioactive ingredients for antioxidant and anti-inflammatory activities. Protection effect of the herb and spice against acute alcohol consumption has been investigated using zebrafish as a vertebrate model. During 30 days bathed in water containing 1% Et-OH and the designated herb or spice, the survival rate of the Et-OH group was decreased sharply (up to 20% at 10 days). The cinnamon-fed group showed the highest and longer survival rate up to 80% up to for 30 days under the presence of Et-OH, while clove-fed group showed 40% survival rate for 25 days. Et-OH group serum exhibited the weakest antioxidant ability from ferric ion removal ability (FRA) assay; FRA ability was increased in the cinnamon-fed group up to 414%, while the clove and laurel group increased 256% and 309%, respectively. Histologic observation and Oil-red O staining showed hepatic tissue damage was severe in the Et-OH group. The cinnamon- or clove-fed group showed much ameliorated hepatic tissue morphology with minimized steatosis. The cinnamon- or clove-fed group showed lower serum GOT and GPT levels than the Et-OH group. Among hepatic tissue extract, the clove-fed group exhibited the lowest level of GOT and GPT. These results suggest that consumption of cinnamon and clove might be beneficial to attenuate progress of acute fatty liver change by alcohol consumption.

댐붕괴 모델링에 관한 연구가 활성화된 시기는 미국 Baldwin Hills 댐(1964)과 Lower Van Norman(San Fernando) 댐(1971) 붕괴 사고 이후이며 1970년대 발생한 Buffalo Creek 댐(서부 버지니아, 1972), Teton 댐(아이다호, 1976), Laurel Run 댐/Sandy Run 댐(펜실바니아, 1977), Kelly Barnes 댐(조지아, 1977) 붕괴 사고로 인해 미국 댐 안전 관리 프로그램의 포괄적 재검토의 필요성이 제기되었다. 국내에서도 연천댐 붕괴(1996년)와 장현저수지와 동막저수지의 붕괴(2002년)로 하류에 위치한 가옥 및 농경지 침수로 인해 재산피해가 발생한 바 있으며, 2005년 비상대처계획 수립을 의무화하는 제도가 도입되었다. 오늘날 댐 붕괴와 붕괴로 인한 유출 수문곡선을 분석하는데 이용 가능한 수많은 도구들이 존재하고 있다. 가장 잘 알려져 있으며 가장 널리 이용되는 모형은 NWS Dam-Break Flood Forecasting Model(DAMBRK; Fread, 1977)이며 국내 댐 저수지 비상대처계획 수립을 위해 많이 이용되고 있다. DAMBRK 모형의 입력자료는 붕괴지속시간, 결괴부측면경사, 최종결괴부바닥표고, 댐붕괴시작수위 등이 요구되며, 이 중 결괴형성과정에 관련된 매개변수의 선정을 위해서는 댐붕괴 사례연구 자료가 활용되고 있다. 모형으로부터 도출된 붕괴유출수문곡선에 대한 적정성 평가는 과거 경험, 공학적 판단, 첨두유량 예측식에 의해 수행되고 있으며 가장 객관적인 기준이라 판단되는 첨두유출량 예측식은 사례연구 자료의 부족으로 인해 높은 불확실성을 안고 있다. 본 연구는 최근까지 개발된 댐결괴 첨두유출량 예측식을 기반으로 국내 건설된 댐의 대다수를 차지하는 필댐에 대해 댐높이, 댐형식별로 예측식의 적정성을 평가하였다.

Arts is the expression of reasoning and conscious life of human and arouse human the concept of existence, utmost emotion and excellent thoughts. Also it makes humans life very abundant. I make it come first to get rid of the art thirst on the opposite sight of technical one for hair as on part of humans body. Next purpose is that to confirm the esthetic value of 'hair arts' by solidify the academic ground of beauty arts through creating 'hair arts' works and learning and make the direction for the beauty industry and education of the next generation. In this study I investigated the Greek myth and the hair styles of ancient Greek Goddesses. On the basis of that symbols I elaborated hair formative works made of metal and studied, analyzed and displayed that. Work No.1 'aphne' pictures the second of changing into a laurel tree avoiding the love. Secondly 'Muse Erato' was exhibited the peaceful figure that have enough the fine melodies. 'Leda' brings out the feature of Leda resembling a swan and the fourth piece, 'Eos' conveys the brilliant and mystery of dawn. So this study conducted based on the concept of practical hair and have made efforts to be close to theoretical manufacturing research needed at making hair arts works and academic one needed at organic design composition for pioneering new field, 'art hair.' I hope these 'hair arts' works make creativity of the practise hair alive. It will be very thankful to me if this study can help even though slightly for splendid beauty arts to make its status firm as a one part of arts, and there are following studies.

This thesis aims to analyze the costume changes according to the ideological transition through the portraits of Napoleon Bonaparte. This study selected 32 color pictures of Napoleon, which was taken during his time as a general to his ascension as Emperor (1785-1815). The study qualitatively analyzed the traits and costume elements in view of the items, color and ornaments of the costume, while studying the effects of the ideological transition. The costumes of Napoleon were categorized into three parts: general, governor and Emperor. Firstly, Napoleon most frequently wore the navy uniforms when taking the portraits as a general. The uniform gave Napoleon the image of strength, youth and intelligence, which reflected the ideology of enlightenment. Secondly, the red-colored administrator uniform, combined with a military coat with culotte, was worn to make the governor look intelligent, which would ascribe to the ideological demand of the enlightenment. Lastly, his portraits as emperor showed him in long white tunica, combined with red-colored coronation cape ornamented with embroidery, ermine fur, and the crown of laurel. This costume denoted both the enlightenment and also the neoclassical trend aspiring for the return to the Greek and Roman era. In this way, the portrait of Napoleon might be expected to reflect the periodical change of the ideology through describing the transition of the costumes. It might be evident that his image of the strong general changed to that of an intelligent governor, which was in demand when the enlightenment idea became popular. When Napoleon became the emperor, his image changed into that of a Roman emperor, which implies that neoclassical ideas were used as source of influence.

Skin wrinkles typically appear as a result of aging processes. One of causes may be the nonenzymatic glycation followed formation of browning products called advanced glycation endproducts (AGEs), an irreversible cross-linked protein. The accumulation of glycated collagen cross-linked in skin inhibits the formation and function of skin tightening agents such as collagen and elastin. To development for anti-wrinkle ingredients from edible plants, MeOH and hot-water extracts were prepared and evaluated for their inhibitory effects of AGEs formation. The activities of both extracts from bay laurel (Laurus nobilis), cinnamon (Cinnamomum loureirii), clove (Eugenia caryophyllate), oregano (Origanum vulgare), rosemary (Rosemarinus officinalis), savory (Satureja hortensis) and star anis (Illicium verum) of western spices, and blackberry (Rubus coreanus), dayflower (Commelina communis), Epimedium koreamun (whole), termunalia frutus (Terminalia chebula) and turkestan rose (Rosa rugosa) of medicinal plants were higher than the others. Of Korean vegetables, however, MeOH and hot-water extract from only Asters caber and green tea showed higher activities, and no activity in Korean marine plants (seaweeds).

The purpose of this work is the development of a method for an effective, less expensive, rapid, and simultaneous determination of three phenolic compounds (caffeic acid, gallic acid, and quercetin) widely present in food resources and known for their antioxidant powers. The method relies on partial least squares (PLS) calibration of UV-visible spectroscopic data. This model was applied to simultaneously determine, the concentrations of caffeic acid (CA), gallic acid (GA), and quercetin (Q) in six herb infusion extracts: basil, chive, laurel, mint, parsley, and thyme. A wavelength range (250-400) nm, and an experimental calibration matrix with 21 samples of ternary mixtures composed of CA (6.0-21.0 mg/L), GA (10.0-35.2 mg/L), and Q (6.4-17.5 mg/L) were chosen. Spectroscopic data were mean-centered before calibration. Two latent variables were determined using the contiguous block cross-validation procedure after calculating the root mean square error cross-validation RMSECV. Other statistic parameters: RMSEP, R², and Recovery (%) were used to determine the predictive ability of the model. The results obtained demonstrated that UV-visible spectrometry and PLS regression were successfully applied to simultaneously quantify the three phenolic compounds in synthetic ternary mixtures. Moreover, the concentrations of CA, GA and Q in herb infusion extracts were easily predicted and found to be 3.918-18.055, 9.014-23.825, and 9.040-13.350 mg/g of dry sample, respectively.

This study evaluated the effects of gamma ray and electron beam (E-beam) to improve the safety of spices for meat processing. The spices (garlic powder, curry powder, turmeric powder, black pepper, white pepper, oregano, parsley, laurel leaf powder, basil, and rosemary) were irradiated by gamma ray and E-beam at 0, 2, 4, 6, 8, and 10 kGy. Total bacterial populations were then enumerated on total plate count agar, and bacteria isolated from the samples were identified by polymerase chain reaction (PCR). In addition, $D_{10}$ values for Bacillus cereus and Staphylococcus aureus inoculated in spices was determined, and the Ames test was conducted for genotoxicity analysis. The contaminated total bacterial populations in spices ranged from 1.5 to 3.8 Log CFU/g, and most of identified bacteria were Bacillus spp., and Staphylococcus spp. However, the bacterial populations decreased below the detection limit (2 Log CFU/g) after irradiation at 4 kGy except for parsley, which required 6 kGy in gamma ray and 8 kGy in E-beam to decrease total bacterial populations below detection limit. $D_{10}$ values were also higher (p<0.05) in E-beam treated samples than gamma-ray treated samples. No genotoxicity was observed in both conditions with and without metabolic activation. These results indicate that gamma ray (>4 kGy and <6 kGy) could be more useful to improve food safety of meat processing spices compared to E-beam.

The purpose of this study is to suggest vegetation management method as the cultural landscape forest of Dongbaek Island which is the district monument. The study area was $20,000m^2$ around the peak area in management as the nature sabbatical area. Vegetation structure type was classified with the criteria of topography, vegetation, management and the management plan was derived from the vegetation structure analysis according to the types. Vegetation structure types were Management-Camellia japonica, Non-management-Eurya japonica, Non-management-Rugged area-Eurya japonica. As the result of vegetation structure, Pinus thunbergii dominated in canopy layer and Camellia japonica and Eurya japonica dominated in Type I and in Type II and III, respectively. Especially, Machilus thunbergii as the climax species in the warm temperate forest were distributed centering shrubs, and as the result of distribution of diameter of breast height, middle size of Celtis sinensis and Machilus thunbergii were distributed in type I, II. Machilus thunbergii were distributed in range of 4 to 44 individuals through the all types. Mean age of canopy layer was 66 year-old and sub-canopy layer was 22.9 year-old. Shanon's species diversity was analysed from 0.5472 to 0.8646. As the vegetation management direction of Dongbaek island, managed Camellia japonica forest was suggested to maintain the regular management and non-managed Eurya japonica forest was required to remove the Eurya japonica and plant the Camellia japonica. In case of non managed Eurya japonica forest in rugged area, vegetation succession was required to laurel forest.

This study was performed to develop a new natural antimicrobial materials by analyzing the effect of extracts obtained from Ten Lauraceae Species on the inhibitory activity against Propionibacterium acnes. The plant materials were collected from Wando and Jeju islands, and the antimicrobial activity of the crude extracts was examined by the agar diffusion method with different part (i.e., leaf and branch), solvents (i.e., distilled water, 80% ethanol, and 100% methanol) and at different ultrasonic extracting times (i.e., 15, 30, and 45 minutes). The control agents used were synthetic antimicrobials, methylparaben and phenoxyethanol, at concentrations of 0.4, 1, 2, and 4 mg/disc. Altogether, extracts of 10 species used in the study showed inhibitory activity, which confirmed their antimicrobial action against acnes. Among these, leaves of Laurus nobilis L. which was extracted in 80% ethanol for 45 min showed the largest clear zone (19.8 mm). Leaves of L. nobilis L., showing highest antimicrobial activities among 10 species, were successively reextracted with n-hexane, chloroform, ethylacetate and n-butanol. As a results, in all fractions except butanol, clear zone above 10 mm were formed. The ethyl acetate fraction showed the highest inhibitory activity (13.3 mm) and the inhibitory activity was significantly higher than that of crude extract (10.2 mm) and phenoxyethanol as a control (12.5 mm).
