Fashions are constantly subject to change, so that forecasting trends in fashion is very difficult and the forecasting is very important. The reason is that forecasting is identifying a hot trend for the next days' business and projecting the future. The purpose of this study is to suggest the realistic forecasting theory identify fashion trends at present, further forecast fashion trends to 1995. For this study, historical models (th historical resurrection model, the historical continuity model) and the art movement model among the behavioral science models which was suggested in 1986 by Geoge B.Sproles were selected. According to this study, was exhibited. This curve was resulted from relation between 1980s fashion trends and the behavioral science models of fashion. Fashion trends to 1995 through will be followings; 1. Body Conscious look as one of the characteristics of modern fashion will bi continued throughout 1990s' fashion trends. 2. The attraction of Mini style was started from the middle of 1980s, recently gets near micro mini and super shouts, These are representative of the historical continuity model. 3. Mini look as revivals of '60s in early 1990s fashion trends. This phenomenon identifies that "Fashion is repetition" 4. When Mini look and super shorts reach, will not progress any more. In this time, will bi seen transfer of style be using classic style. Tat is modern classic will be appeared. also this condition is same from late 1960s to early 1970s. In view of the historical base, the action of the varieted pants will be prominent. 5. Fashion trends which passed through this process will transfer from young look to elegant look. In this time, designers will retrospect '30s and '50s fashion trends, and then will design modern feminine look. 6. Ethnic look, the fashion trend after that condition will be accelated feminine look. This look with the feminine look will reveal rich, colorful, elegance feminine image. 7. In 1980s, activity and function in clothes were demanded. The clothes which are considered these condition will be demanded continuously. 8. The variety of fashion will appear as mixmode and new coordinate look in a clothes simultaneously in fashion of '90s. And these looks will creat mixed beauty. 9. Pop art, op art, graphic art will be not only development of textile but also movement of fashion soul in 1990s. The fashion behavior will be continuously scientificated.

This study was carried out to evaluate the effects of dietary supplementation of different sources of chromium on growth performance, blood profile and carcass trait in growing-finishing pigs. A total of 200 growing pigs (Landrace${\times}$Yorkshire)${\times}$Duroc, average initial weight 8.5 kg) were allotted to 5 treatments with 4 replicates per treatment and 10 pigs per replicate. Five treatments were designated as follows according to the source of chromium. i) Control (No chromium): corn-soybean meal based basal diet, ii) $CrCl_{3}$: control diet+200 ppb Cr as $CrCl_{3}$, iii) CrPic: control diet+200 ppb Cr as Cr picolinate, iv) CrMet-1: control diet+100 ppb Cr as Cr methionine, and v) CrMet-2: control diet+200 ppb Cr as Cr methionine. After the feeding trial, three pigs per replicate (12 pigs per treatment) were slaughtered for the evaluation of carcass traits. Average daily gain (ADG), average daily feed intake (ADFI), and feed: gain ratio (F/G) were not different (p>0.05) among dietary Cr sources. However, whole-period ADG of pigs fed CrPic, CrMet-1 and CrMet-2 diets was higher (p<0.05) than for the control diet. Nutrient digestibility was not different (p>0.05) among dietary Cr sources, but the nutrient digestibility of pigs fed CrPic, CrMet-1 and CrMet-2 diets was higher (p<0.05) than for the control diet. BUN level decreased with more magnitude (p<0.05) in pigs fed Cr during the 20 to 50 kg period. Although both serum cholesterol and triglyceride were different (p<0.05) among treatments, there was no consistent response that could be related to the dietary Cr sources regardless of growth phase. However, the overall data suggested that serum cholesterol level increased as BW of pigs increased. Blood total protein (TP) increased (p<0.05) in pigs fed Cr only during the 90-110 kg phase, and blood creatinine (Creat) level was higher in $CrCl_{3}$ and CrPic treatments than in the control only during the 90-110 kg phase. Backfat thickness was thinner (p<0.05) in pigs fed CrMet-2 than in the control treatment. Therefore, lean percentage was higher (p<0.05) in CrMet-2 than in control pigs. However, dressing percentage and Longissimus muscle area (LMA) were not different (p>0.05) among treatments. In conclusion, dietary supplementation of 200 ppb Cr, via either CrPic or CrMet, improved pig growth performance and nutrient digestibility. Moreover, dietary CrMet supplementation for the growing-finishing pig is evidently remarkable for improving both lean percentage of the carcass and backfat thickness.

현재 우리나라 농업은 농식품 산업과 ICT 융합화로 새로운 가치를 창출하고, 농촌 지역 정보화 확충, 농정 시스템 효율성 제고 등을 통해 성장동력을 확충함으로써 지속가능한 성장을 도모하고 있다. 한편 국내 농업 ICT 융합 기술은 생산 분야 위주로 초기단계 수준에 머물러 있어, 생산 유통 소비단계를 아우르는 체계적인 기술개발과 표준화를 통한 성공 모델의 확산이 필요하다. 또한, 대형 유리 온실의 관제 및 제어 시스템은 외산 제품이 대부분이고, 농식품 ICT 융복합 기술에 관한 표준화 미흡 및 관련 기업의 영세성 등으로 민간 주도의 농식품 ICT 융복합 활성화에 한계가 있다. 그리고 기존의 농업기술에 정보화기술, 자동제어 기술 등 ICT 고유의 기술을 융합시켜 농업의 생산 유통 소비 전 과정에 걸쳐 생산성향상, 효율성 증대, 품질향상 등과 같은 고부가가치를 창출 방안 모색이 필요하다. 따라서 본 논문에서는 국내 농업-ICT 융합 기술 개발 현황, 표준화 동향 및 정책 동향 등을 분석하여 우리나라가 선도할 농업 ICT-융합 기술 분야를 도출하고 향후 표준화 방안을 제시하고자 한다.

Crib wall system은 일반적으로 segmental crib type의 옹벽형식으로 stretcher라는 전 후면 가로보와 세로 방향으로 header라는 버팀보를 연속적으로 쌓아 올리는 공법이다. 이때, stretcher와 header로 구성된 골격 내부에는 흙으로 속채움을 하여 다져, 본 구조체가 일체거동이 가능한 강성체(rigid body)를 형성시킴으로써 배면의 토압에 대하여 저항하는 구조물이다. 따라서, 안정성 해석은 일반적으로 기존의 철근콘크리트 옹벽과 같이 전체 옹벽이 하나의 강성체로 작용한다고 가정하여 토압이론에 의하여 평가하고 있다. 그러나, 변형문제에 있어서 본 구조물은 단순히 하나의 구조체로 가정하여 해석하기가 곤란하다. 왜냐하면, stretcher와 header는 일반 보강토옹벽의 전면 벽체 부재와는 달리 뒷채움재 내에 어떠한 인장 보강재도 삽입되지 않기 때문에 독립된 변위거동을 나타낸다. 또한, 각각의 독립부재로 구성된 재료와 내부채움재의 힘과 변형은 3차원적으로 거동하며 수평토압에 의하여 복합적인 상호거동을 일으키기 때문이다. 따라서, 본 연구는 Crib wall system의 변위경향을 보다 엄밀하게 해석하기 위하여 Brandl(1985)의 full scale 시험 결과를 바탕으로 수치해석 모델을 제시하였다.

Objectives: Blood mercury levels among adults living in certain areas of the Gyeongsang Provinces have been shown to be very high (Kunwee County $29.6{\mu}g/L$, Yeongcheon-city $26.7{\mu}g/L$). The purpose of this project was to determine mercury exposure levels in schoolchildren and factors related with their mercury levels in high mercury exposure areas identifyed by the 2007 Korea National Environmental Health Survey. Methods: From June to September 2010, 1,097 students from grades 3 to 6 at 19 elementary schools participated in this study, including 294 students from 10 elementary schools in Kunwee County, 529 students from Yeongcheon City, 122 students from two elementary schools in Pohang City, North Gyeongsang Province, and 152 students from two elementary schools in Ulsan Metropolitan City. Biological samples from schoolchildren, including whole blood, urine and hair, were collected to measure total mercury at the time of a health check up. Information about children was collected by questionnaire. Total mercury concentrations in blood were measured using the Direct Mercury Analyzer 80 with the gold-amalgam collection method. Results: The mean mercury levels were $2.70{\mu}g/L$ in 1,091 blood samples, $2.25{\mu}g/g-creat.$ in 820 urine samples and $1.03{\mu}g/g$ in 1,064 hair samples. Blood mercury levels in the schoolchildren was slightly higher than the result of $2.4{\mu}g/L$ from a 2006 survey of elementary school children on exposure and health effects of mercury by the National Institute of Environmental Research. However, 0.3% and 4.5% of participants exceeded the reference level of blood mercury by CHBMII ($15{\mu}g/L$) and the US EPA ($5.8{\mu}g/L$), respectively. The reference level of urine by CHBMII ($20{\mu}g/L$) was exceeded by 0.4% of participants. As factors, residence period in the study areas, residence type, father's education level and income all showed significant associations with mercury level in the biological samples. The number of dental amalgam sides showed an association with urine mercury. Fish intake preference and fish intake frequency were important factors in mercury levels. In particular, intake of shark meat and recent intake of shark meat were associated with higher mercury levels. In this regard, participation in the performance of an ancestral rite showed a relation with higher mercury levels. Conclusion: The intake of shark meat was very important factor to high mercury exposure level. It is recommended to monitor and manage students with high mercury exposures who exceeded CHBM II and EPA guidelines, and include blood mercury testing in the Children's Health check up for this province.
