Land cover types of Hustai National Park (HNP) in Mongolia, a hotspot area with rare species, were classified and their temporal changes were evaluated using Landsat MSS TM/ETM data between 1994 and 2000. Maximum likelihood classification analysis showed an overall accuracy of 88.0% and 85.0% for the 1994 and 2000 images, respectively. Kappa coefficients associated with the classification were resulted to 0.85 for 1994 and 0.82 for 2000 image. Land cover types revealed significant temporal changes in the classification maps between 1994 and 2000. The area has increased considerably by $166.5km^2$ for mountain steppe. By contrast, agricultural areas and degraded areas affected by human being activity were decreased by $46.1km^2$ and $194.8km^2$ over the six year span, respectively. These areas were replaced by mountain steppe area. Specifically, forest area was noticeably fragmented, accompanied by the decrease of $\sim400$ ha. The forest area revealed a pattern with systematic gain and loss associated with the specific phenomenon called as forest free-south slope. We discussed the potential environmental conditions responsible for the systematic pattern and addressed other biological impacts by outbreaks of forest pests and ungulates.

The effect of pH on degradation of paper by some fungi, which able to degrade cellulose, was investigated. Trichoderma koningii, Aspergillus nigerand Penicillium nigulosum were cultured at $28^{\circ}C$ for 16 days in the selective medium (PH3, PH4, PH5, PH6, PH7, PH8, PH9, PH10, PHC) containing paper as substrate. Each paper was pretreated with each pH buffer (pH 3∼pH 10, D.W.)prior to addition to the selective medium. Enzyme activities in the each culture medium were measured spectroph to metrically using C.M.C., Avicel, PNPG as the substrates for endoglucanase, exoglucanase and $\beta$-glucosidase, respectively. In all experimental fungi, the enzyme activities of PH3 and PH9 medium were usually much higher than those of other experimental groups. However in the PH6medium, enzyme activity was lower than other groups. To analyze the concentration and pattern of protein in the each culture medium, the medium was concentrated by lyophilization. The protein concentration of PH3 and PH9 medium were relatively high (T.koningii; 6.31mg, 6,19mg, A.niger; 1.62mg, 1.96mg, P.nigulosum;2.50mg, 2.73mg, respectively), but that of PH6 was relatively low. The protein pattern of each medium was analyzed by using SDS-PAGE and VDS Image Master Analysis Program. The concentrations of bands in the each lane were usually high at lane2 (PH3) and lane8 (PH9) and low at lane5 (PH6). Therefore, the incresed cellulolytic activity of fungus against acidified paper could be result of structural change and deterioration of paper caused by being acidified.

The purpose of this study is to present basic data that can express beautiful silhouette by studying visual effect that depend on waist position of basic pants and the change of round belt width and analyzing the study of visual effect of the pattern design as well as the effect of design component. The stimuli are 21 samples: 7 variations of the location of the waistline and 3 variations of the width of the belt. The data has been obtained from 35 fashion design majors. The data has analyzed by frequency, factor analysis, anova, scheffe's test and the MCA method. The visual effects by the location of waistline and the width of belt are composed of 3 factors : horizontal direction factor, vertical direction factor and flexuosity factor. In these factors, horizontal factor is estimated by most important factor. Visual effect is positive when belt width widens as the location of waist line goes down to position of low belt. And in case the location of waist line is in the position of natural waist belt and low rise belt, belt of 3.2cm width is effective visually. The interaction effects between the location of the waistline and the width of the belt have significant differences in all factors. Factor that appears in visual effect of basic pants can be evaluated differently according to pattern of pants and characteristic of body shape. So we may receive better visual assessment if we consider the location of waist belt and width of belt in side of visual effect and image, when we produce pants giving variety to crotch depth.

This study tried to examine the fashion design and style of representative K-Pop boy groups BTS and SEVENTEEN appearing on music shows. The data collection was conducted on 4 music programs(Inkigayo, Music Bank, Show! Music Core, M COUNTDOWN) and YouTube(www.youtube.com) for each boy who worked for 5 years from January 2016 to December 2020. Result analysis utilized the stage scenes and music videos of the title songs of BTS and Seventeen. As for the fashion design and style characteristics of BTS, it was found that overall, the color, pattern, and decoration of the bottom were minimized, and the style was changed mainly by the top of the denim pants. As for Seventeen's fashion design and style characteristics, it was analyzed that plain simple slacks, bright and modest chromatic colors, and geometric and stylistic patterns with street retro sensibility were relatively emphasized, and natural and romantic images appeared a lot. As a result of examining the differences in fashion design and style characteristics between BTS and Seventeen, significant differences were found in color, tone, color scheme, material type, material combination, detail, trimming, pattern, accessories, and fashion image. Overall, it was found that both groups minimized the use of decorative elements such as patterns, details, and trimmings.

디지털시대에 다양한 분야에서 공간정보를 공유하기 위해 여러 국가들은 NSDI를 구축하고 있다. NSDI의 중요한 요소 중 하나는 기본공간정보로 다양한 분야에서 공통으로 공유되는 공간정보(콘텐트)를 의미한다. 여러 연구들이 공간정보 분야 전문가, 사용자 등을 대상으로 한 선호빈도 조사, 외국 사례조사 등으로 기본공간정보 구성항목을 제안하고 있다. 그러나 이와 같은 방법은 기본공간정보 항목 선정결과에 대한 객관적인 검증이 미흡하다. 본 연구는 요인분석을 이용한 통계적 검증을 통해 다양한 분야에서 공통으로 공유되는 실체로 공간정보(콘텐트)가 무엇인지를 분석한다. 이를 위해 우리나라에서 가장 많이 사용되는 국가기본도의 중분류 레이어 104개와 그 외에 다양한 분야에서 많이 사용하는 지적, 영상 등을 포함해 총 109개 레이어의 활용행태를 조사한다. 조사내용은 기본공간정보 활용행태의 특성인 배경자료, 기준자료, 기초자료로서 각 레이어가 사용되는 정도이다. 그리고 이외 다른 목적으로 사용빈도가 높은 기타의 경우를 조사한다. 요인분석 결과 각 활용행태에 따라 5-7개 요인집단들이 도출되었다. 각 활용행태의 요인집단에 대한 분산분석 결과 집단의 평균값 사이에 통계적으로 유의한 차이가 있는 것으로 나타났다. 그리고 각 활용행태에서 평균값이 높은 요인집단의 레이어 항목들은 거의 동일하다고 할 만큼 유사하다. 이와 같은 결과를 바탕으로 본 연구는 교통(도로, 철도), 건물, 수계, 고도, 행정구역, 영상, 측량기준, 지적 등 8개의 주제를 중심으로 기본공간정보 구성체계를 제안한다. 본 연구에서 제안한 기본공간정보를 구성하는 주제정의는 공간정보 공유체계를 구축하는 시작의 단추로 의미가 있다. 제안된 기본공간정보가 다양한 분야에서 공유되기 위해서 실제 표준 형태로 구축되고 유통되는 체계를 갖추어야 하며, 이와 관련된 연구들이 이루어져야 한다.

주성분 분석은 자료압축, 특징추출, 통신이론, 패턴인식 그리고 화상처리등의 컴퓨터 공학분야에서 중요하게 사용되고 있다. Oja(1982,1989,1992)는 확률적 경사 강하법(SGA:Stochastic Gradient Ascent)을 이용한 제한된 헵규칙을 제안하여 주성분 분석에 사용하였다. 그러나, 이 규칙은 이상치에 민감하므로 이상치의 영향을 줄이기 위해, Xu & Yuille(1995)는 통계물리 방법을 이용한 로버스트 에너지함수를 생성하여 로버스트 주성분 분석방법을 제안하였다. 또한 Devlin et.al(1981)은 M-추정량을 이용하여 주성분 분석을 하였다. 본 논문에서는 Oja(1992)의 규칙과 Xu & Yuille(1995)의 로버스트 에너지함수를 이용하여 신경망을 구성하였다. 그리고, Devlin et.al(1981)이 제안한 시뮬레이션조건하에서 실험을 하였다. 실험한 결과와 Devlin et.al(1981)의 결과를 비교, 분석함으로써, 신경망의 성능을 확인하고자 한다.

제주는 농업과 관광이 절대적 비중이므로 강수에 대한 예측/분석은 다른 지역보다 더 중요한 요소로 작용한다. 현재 제주도의 강수 예측은 기상위성을 통해 얻어지는 관측데이터에 수치모델을 이용하나, 다른 지역보다 강수 현상에 대한 변화가 다양하므로 기존의 일반적인 수치모델을 그대로 적용하여 강수 예측/분석을 하기는 쉽지 않고 만족할만한 결과를 얻기가 어렵다. 따라서 제주지역에 맞는 새로운 제주 예측/분석 방법이 연구돼야 할 것이다. 본 논문에서는 합성곱신경망 (Convolution Neural Network, CNN) 기반의 텍스처(Texture) 분석기법을 이용한 제주 강수패턴 분석 방법을 제안한다. 제안하는 방법은 기상위성에서 획득한 제주도 영역에 대한 수증기영상과 지역의 온도정보를 텍스처 영상으로 변환한 후, 변환된 영상들을 합성곱신경망을 이용하여 강수 여부를 분석하는 방법이다. 제안한 방법을 구현하고 실험을 통하여 제안된 방법의 유효성을 보인다.

Recently as large sized urban development and the city ward drifting of population are caused, the urban surface temperature is raised very seriously and rapidly. These artificial developments have destroyed the inner and outer landscapes such as topography and have changed complex local climate such as a sudden rise in temperature, the change of wind field and air pollution. In order to clarify this problem visually, the studies on extracting the thermal infrared and the characteristic analysis of local climate in urban area had been performed by using the sixth band of Landsat TM and ETM+. However, there is a need to alternate Landsat TM and ETM+ because these satellite images are not applied any more. Therefore, in this paper it is proposed to use 2 Aster image (2004.4.17 daily 2b03, 2004.10.10 night 2b03) of EOS AM and to extract the surface temperature. Also, the pattern of surface temperature in urban area and the application possibility in local climate study are proposed by verifying the correlation with A WS data. Also, IKONOS image was used to figure out the artificial development area in visual.

The purpose of this study is to find the differences among the clothing brands through examination of present situation about uniform design in domestic coffee houses and provide the basic materials in developing uniform designs to reflect the brand identity. For research contents and method, the overall circumstances were examined about the domestic coffee houses and their uniforms at large via literature review. Then, characteristics on their 10 uniform designs were reviewed according to item, color, pattern and accessary. The following are results. First, cardigan, cap, and necktie according to the individual brand are added with basis of shirt and apron in composition of coffeehouse's uniform. Second, in cardigan, those colors including black, navy and brown are used, reminding of the coffee. Brand logo or symbol is also presented on it, which addresses the brand image. Third, the kind of shirt consists mainly with long or short shirt blouse and long sleeve or short sleeve pique shirt. Job title or gender differentiates the shape and color. Fourth, one-piece type is commonly applied for the apron. At the same time, a short skirt is put on as well. An image expression is often found by the unique brand color also, but mostly, some dark tones like brown or black are largely used. Fifth, in cap, various kinds are worn including the cap as in the case of baseball, fedora, beret, and hunting cap. In color, black or brown color same to that of apron is common, which fails to show differentiation. Thus, consideration of color remix with application of brand symbol is thought to be an alternative to this.
