Control chart is representative tools of statistical process control (SPC). It is a graph that plotting the characteristic values from the process. It has two steps (or Phase). First step is a procedure for finding a process parameters. It is called Phase I. This step is to find the process parameters by using data obtained from in-controlled process. It is a step that the standard value was not determined. Another step is monitoring process by already known process parameters from Phase I. It is called Phase II. These control chart is the process quality characteristic value for management, which is plotted dot whether the existence within the control limit or not. But, this is not given information about the economic loss that occurs when a product characteristic value does not match the target value. In order to meet the customer needs, company not only consider stability of the process variation but also produce the product that is meet the target value. Taguchi's quadratic loss function is include information about economic loss that occurred by the mismatch the target value. However, Taguchi's quadratic loss function is very simple quadratic curve. It is difficult to realistically reflect the increased amount of loss that due to a deviation from the target value. Also, it can be well explained by only on condition that the normal process. Spiring proposed an alternative loss function that called reflected normal loss function (RNLF). In this paper, we design a new control chart for overcome these disadvantage by using the Spiring's RNLF. And we demonstrate effectiveness of new control chart by comparing its average run length (ARL) with ${\bar{x}}-R$ control chart and expected loss control chart (ELCC).

Lubricanting characteristics in the warm forging have influence on forgeability of products. but Research on deformation characteristic of warm forging on the lubricant and lubricating method lack. This paper deform a bevel gear by warm forging and evaluate deformation loads and quality of products by each lubricants and lubricating method using oil-based lubricants(Soy, Oildag) and water-based lubricants(Deltaforge $\#31$, Renite S-26-X, Deltaglaze $\#151$). In conclusion, the less a deformation load by lubricants the more improvement a quality of product in manufacture of a bevel gear and water-based lubricants in the warm forging reduce a deformation load and improve a quality of products. Especially, Deltaforge $\31$ have excellent characteristic in the warm forging.

This study explores the attributes of the on-line shopping products and prices, and their effects on the customer satisfaction. In doing so, the sample population has been segmented according to their shopping propensity of consumption on clothing to understand the group differences. Based on the previous researches, the researcher have chosen four important characteristics of the customer's shopping propensity. The number of iteration on factor analysis revealed that the sample population can be classified into three different groups; the convenience/pleasure-seeking group, the fashion/utility-seeking group, and the unconcerned group. The significant group differences resulted on the following study variables; the product assortment, the price rationality, and the value of the price. Also, from the product aspect, the characteristic, the assortment, and the expression in order, explained the significant portion of the Y variance. While, on the aspect of price, the rationality, and information in order, significantly contributed on the customer satisfaction.

오늘날 소비자들은 생활수준의 향상과 더불어 제품 구매시, 그 제품이 가지는 가치 중에서 제품이 '사용자의 이미지를 얼마나 잘 대변해 주고 있는지' 하는 상징적인 이미지가 중요한 구매결정 요소가 되고 있다. 이러한 맥락에서 제품 디자인 개발에 있어서 사용자의 상징적 이미지에 관한 정보가 절대적으로 중요하나, 그 구체적인 사용자의 정성적(Qualitative) 정보를 조사하고 분석하는 방법의 개발은 무척 미약한 편이다. 이러한 점에서 사용자의 자아개념 추출 틀(framework)의 개발을 통한 사용자 이미지 정보의 제공은 디자이너에게 유용한 사용자를 이해 할 수 있는 가이드라인(Guideline)정보로써의 궁극적으로 디자인 방향설정에 도움을 줄 수 있을 것이다. 이러한 목적을 위하여 본 연구에서는 사용자군의 자아개념 추출을 위한 21개 언어적 항목을 개발하여 제시했으며, 본 연구에서 사례조사를 통해 개발된 21개 언어적 사용자 자아개념 이미지 평가척도와 사회과학분석 툴(인구통계학적 data분석과 인자분석, 군집분석)의 보완적 활용방안을 모색해 보았다.

본 연구는 한국인의 우쭐과 체면성향이 명품 제품태도에 미치는 영향에 대해 알아보고자 하였다. 선행연구 결과를 토대로 한국인의 우쭐과 체면성향이 명품소비행동과 관련성이 있을 것으로 추론되었으며, 따라서 이러한 한국인의 심리적 특성이 명품 제품태도와 어떤 관계성이 있는 가를 확인하였다. 연구결과 첫째, 한국인의 우쭐성향은 요인분석 결과 6개의 하위요인으로 나타났다. 둘째, 한국인의 체면성향은 요인분석결과 3개의 요인으로 나타났다, 셋째, 한국인의 우쭐과 체면성향 중 명품 제품태도에 미치는 상대적 영향력을 확인한 결과 우쭐성향이 명품 제품태도에 유의미한 영향을 미치는 것으로 나타났다. 또한, 우쭐성향 중 자기중심, 열등감, 자존감, 과시성향 요인이 명품 제품태도에 영향을 미치는 것으로 나타났다. 본 연구결과는 한국인의 우쭐성향에 대한 요인구조를 확인했다는 점에 가치가 있으며, 향후 명품광고를 제작하는 실무자에게 우쭐 심리적 특성의 하위속성을 고려해야만 하는 시사점을 제공해 주었다.

In this study, it is explored how fashion brand slogans are categorized by linguistic characteristics and which linguistic characteristic is effective to improve consumer responses. Only 28% out of 1,346 fashion brands that are investigated are using slogans. Sportswear and men's wear are two product categories more often adopting slogans. A total of 11,113 consumers participated in the experimental study to evaluate slogan characteristics (familiarity, understandability, newness, pleasure), slogan attitude, and brand recall of 30 slogan-brand sets that were categorized by Park's 10 linguistic characteristics. In findings, slogans generating positive attitudes toward slogans and a good rate of brand recall tend to have no brand name in slogan, be written in the second-person view, include a futuristic message, and have information weighted on specialties. Slogan typology suggested based on results may be used for the future research as a basic guideline for the research on fashion brand slogans.

이 연구는 다차원적 관점에 따라 개발된 관여척도를 적용하여 제품관여가 소비자 구매과정에 미치는 영향을 분석하였다. 실증자료 분석결과, 제품별 분석에서 보다 소비자별 분석에서 '구매전 정보탐색'을 비롯한 구매과정의 행동성향이 관여수준에 더 강하게 의존되는 것으로 나타났다. 이는 관여수준이 소비자선택행동의 변화를 설명해주는 구조물이며, 제품관여는 소비자가 제품에 관련되는 정도를 반영하는 변수로 인식되어야 함을 시사한다. 동시에, 관여가 소비자행동에 미치는 영향의 이해와 예언에는 관여수준과 함께 관여의 관저에 대한 이해가 필요하다는 시사를 얻었다.

The reliability of the product can be improved by making the product less sensitive to noises. Especially, it Is important to make products robust against various noise factors encountered in production and field environments. In this paper, the phenomenon of degradation assumes a simple random coefficient degradation model to present analysis procedures of degradation data for robust experimental design. To alleviate weak points of previous studies, such as Taguchi's, Wasserman's, and pseudo failure time methods, novel techniques for analysis of degradation data using the cross array that regards amount of degradation as a dynamic characteristic for time are proposed. Analysis approach for degradation data using robust experimental design are classified by assumptions on parametric or nonparametric degradation rate(or slope). Also, a simulation study demonstrates the superiority of proposed methods over some previous works.

This paper presents the design of DC protection Relay for Light Rail Transit system, which is very beginning product in domestic. Protection Function characteristic, principle and I/O interface including interlock signal has been introduced. The protection algorithm and EMC characteristics have been certified by official organization and Type test report has been introduced. Up to date in domestic, the test procedure for DC Protection relay hasn't been established so the new method and test equipment based on IEC regulations are proposed. Finally the product will be proved based on field test.

In this study, 70 national brands among men's wear brands were selected to examine linguistic characteristics of domestic national men's wear brand names. Linguistic factors which were used in national men's wear brand names were analyzed to understand their characteristics. Formative and semantic characteristics of each brand name were analyzed on the basis of the results from previous studies. It was found that long words with over four syllables are preferred than short words and single words in the form of noun are frequently used for domestic national men's wear brand names in terms of linguistic formality. English is most widely used in brand names, and European languages such as French, Spanish, and Italian are also used frequently under the influence of the country of origin. Next, the analysis result on the semantic characteristics of domestic national men's wear brand names showed that descriptive brand names are used to convey brand information directly and easily, or freestanding brand names which are absolutely irrelevant and newly coined words are chosen to create a characteristic image. In other words, brand names represent detailed business and product category of men's wear by forming a brand image of men's wear (ex. Man, Homme, Zio), and provide the information about properties and benefits related to the product such as dignity, masterpiece, and luxurious lifestyle to consumers by presenting the concept of the brand.
