The purpose of the study is to clarify orange image in the modern fashion. So kinds of costume sample being visual power in orange have been selected from photographs in fashion magazines and divided into the tones : mist(Vp, Lgr, L), bright(P, B), vivid(S, V, Dp). The study was measured by using 27 semantic differential hi-polar scales. The subjects were 50 female students majoring in clothing and textiles, The data was analyzed using the statistical SPSS package. The data were collected using self-administred questionnaires and analyzed by Cronbach $\alpha$, Factor analysis, MDS, ANOVA Sheff test and Regression analysis. The major findings of this research were as follows. 1. Factor analysis has extracted 4 factors of orange image in the fashion. These factor are Attractiveness, Audacity, Hardness and Softness, Cuteness. 2. There were significant difference in visual evaluation of tones. 3. The discrimination among tones was related to cuteness and weight of orange. 4. The image effect on Preference, Buying needs, Pleasant and Riches was consist of complicated sensibility.

Background/Aims: This study evaluated the role of hypomethylating agents (HMA) compared to best supportive care (BSC) for patients with high or very-high (H/VH) risk myelodysplastic syndrome (MDS) according to the Revised International Prognostic Scoring System. Methods: A total of 279 H/VH risk MDS patients registered in the Korean MDS Working Party database were retrospectively analyzed. Results: HMA therapy was administered to 205 patients (73.5%), including 31 patients (11.1%) who then received allogeneic hematopoietic cell transplantation (allo-HCT), while 74 patients (26.5%) received BSC or allo-HCT without HMA. The 3-year overall survival (OS) rates were $53.1%{\pm}10.7%$ for allo-HCT with HMA, $75%{\pm}21.7%$ for allo-HCT without HMA, $17.3%{\pm}3.6%$ for HMA, and $20.8%{\pm}6.9%$ for BSC groups (p < 0.001). In the multivariate analysis, only allo-HCT was related with favorable OS (hazard ratio [HR], 0.356; p = 0.002), while very poor cytogenetic risk (HR, 5.696; p = 0.042), age ${\geq}65years$ (HR, 1.578; p = 0.022), Eastern Cooperative Oncology Group performance status (ECOG PS) 2 to 4 (HR, 2.837; p < 0.001), and transformation to acute myeloid leukemia (AML) (HR, 1.901; p = 0.001) all had an adverse effect on OS. Conclusions: For the H/VH risk group, very poor cytogenetic risk, age ${\geq}65years$, ECOG PS 2 to 4, and AML transformation were poor prognostic factors. HMA showed no benefit in terms of OS when compared to BSC. Allo-HCT was the only factor predicting a favorable long-term outcome. The use of HMA therapy did not seem to have an adverse effect on the transplantation outcomes. However, the conclusion of this study should be carefully interpreted and proven by large scale research in the future.

The purpose of this study was to clarify spatial composition of the staffs at nursing homes for the elderly with dementia. For this, the data was taken from the staffs in 2 nursing homes in Tokyo by the questionnaire from December4 to 28 in 2004. Replicated MDS (Multi-dimensional Scaling) was employed for data analysis. The results of the study were following. Staffs perceived nursing home by four spatial compositions; facility spaces as like sanitation room, laundry, bathroom, washroom, washbowl, social interaction spaces as like training room, inner court/balcony, living room, staff related spaces as like room for staff, treatment room, fundamental living spaces as like bedroom, dining room. According to two-dimensional perceptual map, sanitation room was wanted near by laundry, treatment room was wanted near by room for staff, bedroom was wanted near by dining room, and training room, living room were wanted near by inner court/balcony. On the other hand, washbowl and washroom were desired somewhere near by every spaces. Therefore, simple shaped washbowls are desired to install in dining room, living room, hallways. And sanitation room and laundry were desired somewhere remote by dining room, bedroom, and living room. Responding upper results, it is recommended planning for visual and sense of smell isolation in case of having difficulty in floor structure and circulation.

본 연구는 항만과 도시기능이 충돌하는 현상을 보이는 인천의 사례를 통하여 항만과 도시기능의 연계 방안을 도출하는 것을 연구의 목적으로 하였다. 연구의 분석방법으로 다차원 척도분석을 사용하였으며, 유사성을 갖는 항만도시로 그룹핑 하기 위하여 총 5개 지표(컨테이너 물동량, 인구수, 도시면적, 정기취항 선사 수, RCI[Relative Concentration Index])를 사용하였다. 연구대상은 Containerisation International Yearbook (2010)을 통하여 제시된 18개 아시아 항만도시를 연구대상으로 선정하였다. 분석 결과, 동종 항만도시 군내에 연계지수인 RCI가 인천보다 상회하는 요코하마를 벤치마킹 대상으로 선정하였다. 요코하마는 인천에 비해 항만배후단지의 활용 측면에서 다양하며 '미나토미라이 21'과 같은 항만과 도시의 일관된 정책 사례를 펼쳐 항만과 도시기능의 연계성을 높인 것으로 파악되었다.

본 연구는 동해 남부 연안에서 출현하는 도화망둑 (Amblychaeturichthys hexanema)과 수염문절 (A. sciistius)의 위 내용물을 분석하여 두 어종의 위 내용물 조성을 조사하고, 종 간 그리고 성장에 따른 먹이자원의 분할이 있는지 연구하였다. 도화망둑과 수염문절은 저서성 갑각류를 주로 섭식하는 저서 섭식 육식성어류였다. 저서성 무척추동물과 부유성 먹이 또한 각각 도화망둑과 수염문절의 먹이로써 중요도가 다소 높았다. 중량비 자료를 이용한 non-metric multidimensional scaling (nMDS)와 다변량 분석 (multivariate analyses)에서 두 어종의 위 내용물 조성은 그 차이가 유의하였다. 그러나 두 어종 모두 성장에 따른 위 내용물 조성 변화에서 차이가 유의하지 않았다. 두 어종이 섭식한 먹이생물의 차이는 섭식 행동의 차이와 관련있다. 결론적으로, 본 연구해역에서 두 어종의 위 내용물 분석 결과는 도화망둑과 수염문절 사이에 생태지위 분리의 증거와 먹이 자원에 대한 종 간 경쟁 감소의 가능성을 보여주었다.

본 연구의 목적은 5개의 커피 전문점(스타벅스, 커피빈, 할리스, 엔제리너스, 탐앤탐스)의 경쟁적인 위치를 파악하는 것이다. 서울, 부산, 대구 지역의 거주자를 대상으로 2009년 9월 22일부터 10월 11일까지 20일간 실시하였다. 연구의 목적을 수행하기 위하여 고객이 인지하고 있는 5개 커피브랜드의 유사성을 알아보기 위하여 다차원척도법을 사용하였다. 연구 결과를 살펴보면 할리스와 엔제리너스가 경쟁관계를 유지하고 있음을 알 수 있으며 또한, 탐앤탐스는 할리스와 엔제리너스와 가까이 나타났다. 그러나 업계에서 리더(market leader)인 스타벅스와 스타벅스의 뒤를 따르고 있는(market follower) 커피빈은 개별적으로 독특한 정체성을 가진 브랜드로 인식되고 있음을 알 수 있다. 이 연구 결과에 따라서 마케팅 전략 수립을 필요로 하는 마케터에게 도움이 될 것이다. 향후 연구에서는 다양한 변수를 포함한 철저한 조사가 필요하다.

We investigated seasonal changes in the mesozooplankton community structure in November 2006 and February, May, and August 2007 at 12 stations in the semi-enclosed Muan Bay, Korea. Forty taxa were sampled, with an average abundance ranging from 1,459 to 20,078 indiv. $m^{-3}$; the highest abundance was detected in August 2007, and the lowest in February 2007. Acartia omorii, A. hudsonica, A. ohtsukai, Bestiolina coreana, Calanopia sp., Paracalanus parvus s. l., Cirripedia larvae, Decapoda larvae, and Gastropoda larvae were the most abundant taxa detected. The species diversity of the mesozooplankton was high around the inner regions in August 2007 but it was relatively low in November 2006. Non-metric multidimensional scaling (nMDS) revealed significant differences in the structure of mesozooplankton community among the seasons. Canonical correspondence analysis (CCA), performed to examine the relationships among dominant taxa, stations, and environmental variables, showed that most species of copepods were positively correlated with temperature, salinity, chlorophyll a, and COD concentration. Our results suggested that the mesozooplankton community structure observed in this study might be affected partly by the seasonal changes in environmental variables, such as the status of the sluice gates (i.e., open or closed) and the in situ production of resting eggs by major copepods.

본 논문에서는 라운드 함수의 업데이트 함수로 SP 구조를 사용하고 비밀 S-box가 적용된 GFN(Generalized Feistel Networks) Type I, Type II, Type III에 대한 안전성을 분석한다. 이 환경에서 공격자는 S-box에 대한 정보를 갖지 못한다. 인테그랄 공격 기법(Integral attack) 기반의 선택 평문 공격으로 9 라운드(Type I), 6 라운드(Type II), 6라운드(Type III)에 대한 비밀 S-box 정보를 복구할 수 있다. 선택 암호문 공격으로 전환할 경우 GFN Type I의 16 라운드까지 비밀 S-box의 정보가 복구된다. 결론적으로 m비트 비밀 S-box와 $k{\times}k$ MDS 행렬이 라운드 함수로 사용된 GFN Type I, Type II, Type III에 대하여 비밀 S-box를 복구하는데 ${\frac{2^{3m}}{32k}},{\frac{2^{3m}}{24k}},{\frac{2^{3m}}{36k}}$만큼의 시간복잡도가 필요하다.

Using Multi-Dimentional Scaling(MDS) method, this paper analyzes the differences of acoustic properties of Korean phonemes projected as distances on a plan space. The phonemes were extracted from mono-syllables frequently occurring in daily conversation. From the distances between vowels we found that the distances between vowels /∂/ and /w/, /o/ and /u/, and vowels /$\varepsilon$/ and /e/ were relatively too short separate automatically. From the analysis of consonants. we found short distances between 1) phonemes in each phoneme group, 2) nasals and liquid /r/ of work initial, 3) nasal /n,m/ and liquid /l/ of word finals. But nasals, liquids and plosives of word initials had enough distances to be separated from those of word finals in automatic recogniation.
