Opinion Mining is one of the application domains of text mining which extracting opinions from documents, and much researches are currently underway. Most of related researches focused on the sentiment classification which classifies the documents into positive/negative opinions. However, there is a little interest in extracting the features characterizing the individual product. In this paper, we propose the technique classifying the opinion documents according to the product features, and selecting the those features characterizing each product. In the proposed method, we utilize the document clustering technique and develope a new algorithm for evaluating the similarity between documents. In addition, through experiments, we prove the usefulness of proposed method.

The purpose of this study was to examine the relationship between online apparel impulse buying behavior and apparel website characteristics. The data were collected using an online survey with a structured questionnaire. To recruit participants, online surveys were collected and a total of 236 college students were used in the study. The results of factor analysis showed that website characteristics consisted of two factors (i.e., promotion, product/policy information). The results of MANOVA and multiple regression showed that the impulse purchase group evaluated the website where they bought the last apparel item significantly better in promotion and product/policy information than the non-impulse purchase group. Based on the results, H1, H2, and H3 were supported. The evaluations of the characteristics of websites where impulse purchases and non-impulse purchases of apparel products were made were significantly different.

The effect of defatted and dehydrated beef muscle on the physical properties of thermoplastically extruded defatted soybean, cottonseed, peanut and sunflower seed flours were investigated. To minimize the adverse effect of meat fat and to increase the mixing efficiency of the meat with defatted oilseed flours at a given moisture level, beef muscle was extracted with chloroform-ethanol(2 : 1) at 2$0^{\circ}C$ and air dried. The variety of oilseed flours used had greater effects on color, expansion, bulk density, water absorption rate and textural strength of the extrudate than did the added level of defatted, dehydrated beef muscle (0 to 20% on a dry weight basis).

최근 고층건물 화재의 대표적 사례인 부산 해운대 우신골드스위트 주상복합건물 화재 확대의 주요 원인으로 작용했던 석유화학제품 중 배관보온재를 감싸고 있는 보온필름의 화재특성에 대해 연구를 하였다. 본 화재결과 배관보온필름이 화재취약성을 가지고 있는 것으로 확인되었다. 하지만 명확한 법적규제가 없는 것과 시공비 절감을 위해 대부분의 공사업자들은 비난연제품으로 시공을 하고 있는 실정이다. 따라서 본 연구에서는 이러한 잘못된 시공으로 인한 위험성을 알리고자 하는데 목적이 있다. 연구방법은 국내에서 생산된 마감용 배관 보온필름 네 종류를 사용하여 화재특성을 분석하였다. 네 종류 중 두 종류는 난연성능이 있는 제품이고 나머지 두 종류는 난연성능이 없는 제품으로 선정하였다. 실험은 제품의 열방출률을 알기위해 콘칼로리미터를 사용하였고 또한 실제 피트 내에 배관보온필름 화재를 묘사하기 위해 45도연소시험기를 사용하여 연소실험을 하였다.

Pilling 현상은 우리의 일상생활에서 볼 수 있는 흔한 일이다. 직물에 있어서 Pilling 현상은 제품의 외관과 촉감을 나쁘게 하고 제품의 수명을 저하시키는 현상 중의 하나이다. 이러한 Pilling현상의 원인은 크게 2가지 측면에서 구분되어 진다 첫째는 섬유가 정전기를 띄면서 주위의 이물질들을 끌어 들여 그러한 이물질이 pill을 형성하는 경우와 둘째는 섬유자체가 pill을 형성하기 쉬운 특성을 지니는 경우로 구분된다. (중략)

The aim of this study is to grasp the features of the object which reveals its own specific purposes, and to apply them to the product concept and design forms when designers develop products. For this study, the subjects of the experiment were chosen to fill out a basic questionnaire, and an image analysis of them was performed. After the analysis, the functional design elements of the subjects were extracted and coded. They preyed the correlation between the results of the image analysis and the characteristics of the subjects. The questionnaire was carried out to determine the characteristics of the subjects. As the features of specific products were extracted through this experiment, they can be used as basic data to analyze consumer needs and to better understand the products when we design for them. This can be useful fundamental data enabling designers to understand products easily and to establish concepts for their designs. In the case of the MP3 player in this study, the results of the image analysis of it are turned out to be sound quality, compatibility, portability, employment, interface, and personality. Their respective related features were investigated as well. The important features of designing the MP3 player were presented. Through this fundamental study, it will be possible to understand consumer's needs more effectively, which will bring about the development of the fundamental basis of various fields in design.

Once powder base makeup products are applied to the skin, the products are formed a film and attached on the skin for 8 to 12 hours. The makeup film is deformed by secretions such as sweat and sebum secreted from the skin. Thus, durability of the film is an important quality factor in the makeup and its evaluation is also important. In this study, characteristics of the semi-finished powder products such as water absorption, oil absorption, water repellent and oil repellent were evaluated in a number of ways. Also, simple methods, which are not affected by evaluation conditions such as a difference between sweat and sebum secretion, temperature and humidity, were examined to predict the durability of the products. We measured water absorption, oil absorption, water repellent and oil-repellent properties of semifinished product by tablet, capillary and dipping method and then compared with the data of color difference meter and ROBO skin analyzer. Results showed that the durability of powder base makeup products was associated with more oil absorption and water-repellent characteristics than water absorption and oil-repellent. Oil absorption characteristics by tablet and capillary method and water-repellent characteristics by dipping method provides a simple and quick method to precdict the durability of the makeup products.

소프트웨어 제품의 품질을 보증하는 일은 매우 중요하며, 국제표준인 ISO/IEC 9126은 소프트웨어 품질 및 특성 및 측정 메트릭 표준을 제공하고 있다. 이때 ISO/IEC 9126에서는 소프트웨어를 프로그램, 절차, 규칙 및 관련문서로 한정하고 있기 때문에 데이터의 품질에는 적용할 수 없다. 본 논문에서는 데이터 품질 평가 및 제어를 위하여 데이터 오류 형태를 분류하고, 이를 기반으로 데이트 품질 특성 및 부특성을 분류한다. 데이터 품질 특성 분류는 ISO/IEC 9126에 정의한 소프트웨어 품질 특성을 데이터 오류 형태에 대응시켜 추출한다. 본 논문에서 제시하는 데이트 품질특성 분류는 지식 공학(knowledge engineering)시스템이 최종 사용자에게 제공하는 데이터나 지식의 품질 측정 및 제어에 기준이 된다.
