A Gram-positive strain designated as MSL-$14^T$ isolated from a soil sample collected from Bigeum Island, Korea, was subjected to polyphasic taxonomy. The isolate was strictly aerobic. Cells were short rods and motile. Optimum growth temperature and pH was 28$^{\circ}C$ and 7.0, respectively. It was characterized chemotaxonomically as having a cell-wall peptidoglycan type based on LL-2,6-diaminopimelic acid and MK-$8(H_4)$ as the predominant menaquinone. The major fatty acids were iso-$C_{16:0}$, $C_{17:1}$ omega8c, and $C_{18:1}$ omega9c. The G+C content was 67.6 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain MSL-$14^T$ is affiliated to the genus Nocardioides and formed a distinct lineage within the genus. MSL-$14^T$ showed highest sequence similarity to Nocardioides aestuarii JCM $12125^T$, having a similarity of 96.5%. Based on the 16S rRNA gene sequence divergence and phenotypic characteristics, it is proposed that strain MSL-$14^T$ should be classified as representing a novel member of the genus Nocardioides, for which we propose the name Nocardioides tritolerans sp. novo The type strain is strain MSL-$14^T$ (=KCTC $19289^T$=DSM $19320^T$).

Current global textiles and fashion industries have gradually shifted focus to high value-added, high sensibility, and multi-functional products based on new human-friendliness and sustainable growth technologies. Textile design CAD systems have been developed in conjunction with computer hardware and software sector advances. This study compares the patterns or images of actual woven fabrics and virtual fabrics prepared with a textile design CAD system. In this study, several weave structures (such as fancy yarn weave and patterns) were prepared with a shuttle loom. The woven textile images were taken using a CCD camera. The same weave structure data and yarn data were fed into a textile design CAD system in order to simulate fabric images as similarly as possible. Similarity Index analysis methods allowed for an analysis of the index between the actual fabric specimen and the simulated image of the corresponding fabric. The results showed that repeated small pattern weaves provide superior similarity index values than those of a fancy yarn weave that indicate some irregularities due to fancy yarn attributes. A Complex Wavelet Structural Similarity(CW-SSIM) index resulted in a better index than other methods such as Multi-Scale(MS) SSIM, and Feature Similarity(FS) SSIM, across fabric specimen images. A correlation analysis of the similarity index based on an image analysis and a similarity evaluation by panel members was also implemented.

This study: 1) identifies differences in consumers' perceived similarity of extended products to their parent product in terms of brand attributes, 2) identifies the influence of the perceived similarity on consumer's attitude toward and purchase intention of extended products (i.e., brand extension effect), and 3) examines the moderating effect of Brand Relationship Quality (BRQ) on brand extension effects. A survey questionnaire was distributed to a convenience sample of individuals aged 20-39. A total of 576 valid responses were used for the final analysis. The results showed that: 1) the consumers perceived more similarity in the extended products when the extended products maintain more consistent attributes with their parent product, 2) the higher the perceived similarity was then the higher the brand extension effect, and 3) brand relationship quality moderated the influence of perceived similarity on attitude and purchase intention. When consumers build a high relationship quality with a brand, then the brand extension effect is likely to be high regardless of the perceived similarity of the extended products. This study consequently has its own contribution in that it empirically examined the brand extension effect in the fashion field and evidenced the role of BRQ in brand extension.

In mass customization, the focus is variety and customization through flexibility and quick responsiveness. Mass customizers seek to provide personalized, custom-designed products at low prices to give customers exactly what they want and to provide sufficient variety in products and services. The idea of the product family is the most adequate approach to realize mass customization. An understanding of customer needs using functional decomposition becomes necessary to enhance the performance of the product family. This paper focuses on functional architecture modeling based on customer need regarding sub-functions for the product family. A quantitative functional model captures product functionality and customer need. Based on customer need ratings and sub-function, a product-function matrix was created. Additionally, a product-product matrix was generated to provide a similarity index among product families. A case study for implementing the functional architecture modeling was performed on the single use cameras.

유사문장의 식별 및 통합을 위하여 문장의 구성성분, 품사, 절유형, 위치 등이 미치는 영향을 조사하고 유사도측정 공식과 통합방안을 모색하였다. 문법적 요인보다는 문장간에 일치하는 단어의 수가 유사성에 영향을 미치며 표제어와 기능절도 관여되었다. 문장간의 유사도 측정 공식은 설튼의 유사도 측정식과 코싸인계수를 혼합하여 사용하였다. 유사문장들의 통합에서 절들의 대체 방법을 사용하였는데 앞으로는 단어들의 대체 방법으로 전환하여야 할 것이다.

Clustering algorithms with different similarity measures are commonly used to find an optimal clustering or close to original clustering. The recovery level of using Euclidean distance and distances transformed from correlation coefficients is evaluated and compared using Rand's (1971) C statistic. The C values present how the resultant clustering is close to the original clustering. In simulation study, the recovery level is improved by applying the correlation coefficients between objects. Using the data set from Spellman et al. (1998), the recovery levels with different similarity measures are also presented. In general, the recovery level of true clusters was increased by using the correlation coefficients.

This paper shows that the solutions to the perturbed dierential system $$y^{\prime}=f(t,y)+{\int}_{t_o}^{t}g(s,y(s))ds+h(t,y(t),Ty(t))$$ have bounded property. To show this property, we impose conditions on the perturbed part ${\int}^{t}_{t_o}g(s,y(s))ds+h(t,y(t),Ty(t))$ and on the fundamental matrix of the unperturbed system y' = f(t, y).

유사한 생물학적 특성을 가진 유전자 산물을 검색하는 것은 생물정보학 연구에 필수적인 기술이다. 현재 대부분의 생물학 데이타베이스에서 Gene Ontology의 용어를 사용하여 유전자 산물의 생물학적 특성을 기술하고 있다. 본 논문에서는 이런 유전자 산물의 주석 정보를 사용해 의미적으로 유사한 유전자 산물을 검색하는 방법을 제안한다. 이를 위해 우선 정보 이론에 기반한 유전자 산물간의 의미적 유사도를 정의하였다. 그리고 이 유사도를 이용한 의미적 유사성 검색 알고리즘을 제안하였다. 의미적 유사성 검색을 처리하기 위해 Fagin의 문턱값 알고리즘(threshold algorithm)을 다음과 같이 변형한 기법을 사용하였다. 우선 사용하는 유사도 함수가 단조 증가 성질을 갖지 않기 때문에 유사도 함수에 맞는 문턱값을 재정의 하였다. 또 역색인 리스트의 구조를 사용하여 중간 검색을 생략할 수 있는 클러스터 스키핑 기법과 역색인 리스트 액세스 순서를 제안하였다. 실제 GO와 주석 정보를 이용하여 성능 평가를 했으며 제안한 알고리즘은 효율적인 알고리즘임을 보였다.

컴퓨터 프로그램의 표절 또는 복제에 대한 유사도 검출은 구현에 사용된 프로그래밍 언어, 분석 대상 코드의 종류에 따라 각기 다른 감정 방법과 도구가 필요하다. 최근 들어 증가하고 있는 내장형 시스템의 목적 코드에 대한 유사도 감정은 원시 코드와 비교해 더욱 복잡한 과정 및 고도의 기술과 함께 상당한 자원을 요구하고 있다. 본 연구에서는 목적 코드를 대상으로 역 어셈블리 기법의 적용과 같은 역공학 방법을 이용하여, 목적 코드의 어셈블리어 변환을 통한 어셈블리어 레벨에서의 함수 단위 유사도 감정 방법에 관하여 연구하였다. 그리고, 어셈블리어 레벨에서의 유사도 비교를 위해 코드의 구문분석을 통한 명령어 및 오퍼랜드 테이블을 생성하고, 이를 대상으로 유사도를 검출할 수 있는 도구의 설계에 관하여 기술하였다.

This study conceptually approaches and clearly compares the similarities and differences of fashion and architecture through a focus on their correlations. This study identifies the conceptual definitions of functional minimalism by an examination of function that represents the largest similarity between architecture and fashion. This study classifies the nature of functional minimalism and studies cases for each architectural classification in the areas of: the simplicity of a structure, unitarity pursuit of economic value, repeatability in an efficiency unit, reducibility stressing property, and multi-functional spatiality. The characteristics of functional minimalism fashion are distinguish as: simplicity in a structure that highlight structural lines in non-decorated design, unitarity pursuit of economic value represented in united process and pattern for its economic effect, repeatability in an efficiency unit represented through the repeated decoration of a functional unit, reducibility stressing a property that emphasizes property with a dominant design element through a highlight of the characteristics of materials and multi-functional spatiality that represents variability in clothes through an expansion of limited spatial function. This study approaches each discipline with a clear understanding of the differences between the two and suggests standards for a comparative study of architecture and fashion.
