  • The purposes of this study were to classify shopper types based on clothing shopping orientations and to identify the differences in store selection criteria and demographic characteristics by shopper types. The questionnaire was administered to female and male undergraduate and graduate students living in Seoul. Of 330 returned questionnaires, 319 were used in the statistical analysis which were factor analysis, cluster analysis, $\chi$$^2$-test, and One-way ANOVA. The results of this study were as follows: 1) Clothing shopping orientations had six factors: recreational shopping, name conscious shopping, economic shopping, fashion oriented shopping, convenience shopping. and individualistic shopping. Cluster analysis identified that clothing shopping orientations had four groups: recreational cluster, individualistic cluster, demanding shopper cluster, and convenient brand conscious shopper cluster. 2) Clothing shopping orientations were significantly different in relation to the demographic characteristics such as gender, major field of study, expenditure on clothing, pocket money, and family income level. 3) Store selection criteria had five factors: service quality, physical store environment, sales personnel, shopping convenience, and other attractions. 4) There were significant differences in physical store environment, shopping convenience, and other attractions according to the shopper clusters.

  • Immune-inspired intrusion detection is a promising technology for network security, and well known for its diversity, adaptation, self-tolerance, etc. However, scalability and coverage are two major drawbacks of the immune-inspired intrusion detection systems (IIDSes). In this paper, we propose an IIDS framework, named GEP-IIDS, with improved basic system elements to address these two problems. First, an additional bio-inspired technique, gene expression programming (GEP), is introduced in detector (corresponding to detection rules) representation. In addition, inspired by the avidity model of immunology, new avidity/affinity functions taking the priority of attributes into account are given. Based on the above two improved elements, we also propose a novel immune algorithm that is capable of integrating two bio-inspired mechanisms (i.e., negative selection and positive selection) by using a balance factor. Finally, a pruning algorithm is given to reduce redundant detectors that consume footprint and detection time but do not contribute to improving performance. Our experimental results show the feasibility and effectiveness of our solution to handle the scalability and coverage problems of IIDS.

  • We report the development of a new selection system for the transformation of pepper plants by mannose. In order to achieve this, we first tested several factors related to regeneration conditions. Among the 30 inbred lines examined, line P9l5 was able to generate shoots at the highest rate from both cotyledons and hyporotyls in MS media. A dosage curve for optimizing the selection conditions was established by mixing mannose (range 0-50 g/L) and sucrose (range 0-30 g/L). The least selection pressure on shoot formation was created by a mixture of sucrose and mannose at 20 g/L and 15 g/L, respectively, and the threshold for ultimate tissue death was 50 g/L of mannose irrespective of the sucrose concentration. However, we found that mannose itself was not the sole inhibitor of pepper shoot development. High concentrations of sucrose (30 g/L) contributed additively to the inhibition of shoot formation at higher mannose concentrations. Genotype preference is a major factor that enhances regeneration ability in mannose media, as was observed in MS media. P9l5 and P410 line had high regeneration rates under mannose selection conditions in the presence of Agrobacterium infection. Different virulence levels of Agrobacterium strains did change the regeneration rates, probably due to interaction with the specificities of the inbred lines. Taken together, P9l5 offers the best pepper inbred line for transformation and we recommend a selection condition of 20 g/L of sucrose and 15 g/L or more of mannose up to 50 g/L in media.

  • 문화 관광 축제에 대한 많은 선행 연구가 진행되었으나, 축제장에서 판매되고 있는 음식 메뉴에 대한 연구는 많이 진행되고 있지 않은 실정이다. 축제에서 음식의 중요성을 감안해 볼 때 관람객을 만족시키는 주요 선택 속성을 도출하는 것은 매우 중요한 일이라 할 수 있다. 이에 본 연구에서는 FGI를 통해 도출된 선택 속성을 바탕으로 컨조인트 분석방법을 이용하여 그 중요성에 대해서 분석하였다. 먼저 가격은 가장 영향력 있는 변수로 분석되었으며 주문후 음식을 받는데 걸리는 시간, 메뉴, 장소의 순서대로 분석되었다. 또한 군집분석을 통하여 두 개의 군집으로 구분한 후 각각의 군집에 대하여 분석한 결과 두 군집 중 많은 수의 응답자가 포함된 군집 1의 경우에는 가격 요인(31.62%)이 가장 우선시 여기고 있으나, 군집 2에서는 음식 제공 소요 시간(31.07%)이 가장 중요한 요인으로 분석되고 있어 약간의 차이를 나타내고 있다. 이러한 연구 결과를 토대로 축제 음식 메뉴에 대한 다양한 시사점을 제시하고 있다.

  • The peroxisome proliferator-activated receptors (PPARs) are members of a superfamily of nuclear hormone receptors. Lots of studies in rodents and humans have shown that PPARs were involved in lipid metabolism and adipocyte differentiation. The main objective of this work was to detect the single nucleotide polymorphisms (SNPs) in whole coding regions of peroxisome proliferator-activated receptor alpha (PPAR-$\alpha$) and gamma (PPAR-$\gamma$) genes with approach of single strand conformation polymorphism (SSCP) in the chicken population of Arber Acres broiler, Hyline layer and three Chinese native breeds (Shiqiza, Beijing You, Bai'r). Two SNPs of C1029T and C297T were found in chicken PPAR-$\alpha$ and PPAR-$\gamma$ genes respectively and each SNP found three genotypes in the experimental populations. The results showed that the distribution frequency of 3 genotypes in Arber Acres broiler, Hyline layer and Chinese native breeds had significant differences on the PPAR-$\alpha$ and PPAR-$\gamma$ gene respectively (p<0.01). Furthermore, in the PPAR-$\alpha$ gene, the results of least square estimation for genotypes and body composition traits showed the BB genotype birds had higher abdominal fat weight (AFW) and percentage of abdominal fat (AFP) than AA genotype birds (p<0.05). From these we conjecture the PPAR-$\alpha$ and PPAR-$\gamma$ genes were suffered intensive selection during the long term commercial breeding and the PPAR-$\alpha$ gene may be a major gene or linked to the major genes that impact chicken fat metabolism and the SNPs could be used in molecular assistant selection (MAS) as a genetic marker for the chicken fatness traits.

  • Now that 15 years have passed since its introduction to 4 year college in Korea and we have 51 majors in the field of Intoner design established at 47 universities as of 2003, we are in the position to seek the improvement of its educational qualify. With a view to provide data for the setup of proper educational purpose, it has classified their divisions(departments) according to their major names and belonged colleges of the universities and considered their geographical distributions, groupings of curriculum, their framing and features of a standard curriculum. 1)Divisions of the universities where the major of interior design belongs are divided into three categories of design division (design 8t arts, arts), home economics division (home economics, natural science) and architectural division. For the development of the major, universities to which circumstances permit are recommended to establish an independent college of interior design following the . cases in the US. 2) Geographical preponderance of interior design major on Seoul and Gyeongsang Province is desired to be improved. 3) Curriculum of interior design, which is classified into introduction, history of interior design, theory of interior design, design of interior space, digital technology, design elements of inner space, technology of interior design, behavior of environmental psychology, design management and other subjects, was made into a table by divisions. To sum up, curriculum of interior design concentrates on basic design theory throughout all divisions. In connection with the selection of division by high school-graduates or their parents, design division is recommended for those who desire to major in design elements and design management, home economics division for those who desire to major in space design and behavior of environmental psychology and architectural division for those who desire to major in Interior space design, interior design technology and regulations. 4) This research can contribute to the settlement of desirable curriculum for the interior design education, thus upgrading the education level of the major in Korea.
