The purpose of the study was to investigate the hedonistic motives experienced by consumers in the apparel buying process. We carried out in-depth interviews by 32 women living in Pusan and to examine the hedonistic motives related to the apparel buying process. It was conducted and analysed by the Spradley's developmental research method.The results showed that the hedonistic motives in apparel buying process, consisted of four components at least, such as Symbolism, Conformity, Distinction, and Impulsiveness. Symbolism represented the social-psychological aspects related to the apparel buying process, such as occupation, role, and self-image etc. Conformity in the apparel buying process was usually influenced by mass-media, and companions. Consumers had strong needs of distintion for self-actualization and self-esteem in apparel buying process. The impulsiveness in apparel buying process were related to the antecedent moods, affection, tastes, price, display, and sales person or accompanied friends. We found that the hedonistic motives in the apparel buying process connected with the emotional responses and were played an important role on the consumer satisfaction in the apparel buying process. They provide informations about hedonistic motives of apparels to consumer behavior researchers and retailers related to apparel products.

In this paper, we proposed the content-based music information retrieval technique using some MPEG-7 low-level descriptors. Especially, pitch information and timbral features can be applied in music genre classification, music retrieval, or QBH(Query By Humming) because these can be modeling the stochasticpattern or timbral information of music signal. In this work, we restricted the music domain as O.S.T of movie or soap opera to apply broadcasting system. That is, the user can retrievalthe information of the unknown music using only an audio clip with a few seconds extracted from video content when background music sound greeted user's ear. We proposed the audio feature set organized by MPEG-7 descriptors and distance function by vector distance or ratio computation. Thus, we observed that the feature set organized by pitch information is superior to timbral spectral feature set and IFCR(Intra-Feature Component Ratio) is better than ED(Euclidean Distance) as a vector distance function. To evaluate music recognition, k-NN is used as a classifier

This study explores the characteristics of calculus students' and instructors' discourses on the derivative using a communicational approach to cognition. The data were collected from surveys, classroom observations, and interviews. The results show that the instructors did not explicitly address some aspects of the derivative such as the relationship between the derivative function (f'(x)) and the derivative at a point (f'(a)), and f'(x) as a function, and that students incorrectly described or used these aspects for problem solving. It is also found that both implicitness in the instructors' discourse, and students' incorrect descriptions were closely related to their use of the word, "derivative" without specifying it as "the derivative function" or "the derivative at a point." Comparison between instructors' and students' discourses suggests that explicit discussion about the derivative including exact use of terms will help students see the relationship that f'(a) is a number, a point-specific value of f'(x) that is a function, and overcome their mixed and incorrect notion "the derivative" such as the tangent line at a point.

EBPP는 소비자, 사업자간에 고지서 발송, 접수 및 지불을 네트워크를 통하여 전자적으로 처리하는데 필요한 환경을 의미하며, 인터넷을 기반으로 하여 전자우편 혹은 웹 페이지를 통하여 고지서를 처리한다 EBPP 시스템은 크게 소비자, 사업자 그리고 은행간의 거래로 이루어 지지만 컴퓨터 및 인터넷의 보급의 한계 등의 문제로 현재로서 모든 고지서를 전자적으로 처리하는 것은 무리가 따른다. 그럼에도 불구하고 EBPP 시스템은 1) 경쟁력 확보를 위해 기업/금융 기관들이 인터넷을 통한 고품질 서비스 개발에 주력하는 추세이고, 2) 고객과의 보다 긴밀한 관계 유지를 위한 수단 제공하며, 3) 인터넷 등 온라인 통신 인구가 급격한 증가(2701년에 전체 인구의 약 50%가 활용할 것으로 전망)하고 있으며,4) 소비자를게 보다 편리한 지불방법 제시해주며, 5) 또 다른 마케팅 매체로 활용 가능하므로 앞으로의 전망이 매우 밝다. EBPP시스템은 크게 금융기관, 기업, 소비자 부분으로 구성되며, 소비자와 접촉 방법으로는 대표적으로 Web과 전자우편을 생각할 수 있으며, EBPP 시스템을 구축하기 위해서는 기본적으로 상접 혹은 기업에서 청구에 필요한 정보를 등록시키는 통합 청구서버(Bill consolidation server), 소비자에게 청구 가능한 정보를 갖고있는 청구 제시서버 (Bill presentment server), 소비자의 지불요청에 따라 은행으로부터 지불을 요구하는 지불서버(Payment gateway) 등이 필요하며, 이들 각각의 서버들의 구성 요소들은 제공하는 서비스에 따라 달라질 수 있다. 통합 청구서버에서 청구 제시서버로 전송되는 청구 건은 통상적으로 실시간 처리되는 것이 아니라 통합 청구서버에 존재하는 Spool DB에 저장되어 그 양이 일정한도를 넘어서면 자동 전송되도록 하여, 망의 할용도를 높이는 역할을 수행한다. 청구 제시서버의 DB에 등록된 청구 건은 인터넷을 통해 소비자에게 청구되며, 소비자에게 전송 되는 청구서는 사용자DB를 참조하여 사용자가 미리 정의한 원하는 형태로 변환되어 전달되며, 필요시 암호화 과정을 거치는 것이 가능해야 한다. 전송된 청구서는 전자우편의 경우, 암호해독이 가능한 전용 브라우저를 통해 열람 되며, 이는 다시 전용 브라우저를 통해 지불인증이 승인되어 청구 제시서버에게 전송된다. EBPP 시스템의 제어 흐름은 크게 기업이 청구 정보를 소비자에게 제시하는 흐름과 소비자의 지불 승인으로 인해 기업이 은행에 지불을 요구하는 흐름으로 구분할 수 있다. 본 논문에서는 통합 청구서버 및 정구 제시서버의 역할 및 구성 요소들에 대해 서술하고, EBPP 시스템과 연동하여야 하는 메일 서버와의 상호 작용에 대해 서술할 것이다. 본 시스템을 아직 구현이 되지 않은 관계로 시스템의 성능 등의 수치적 결과를 제시할 수 없는 상태다.

This study describes injection locking phenomena for multi-frequency generator design. For the design of the multi-frequency generator, we describe the basic theory of injection locking phenomenon and conduct a single injection locking experiment based on it. The experiments was conducted by applying injection signals that vibrates consistently to oscillators which vibrates unstablely compared to injection signals. Injection signal was applied using a Howland current source and circuit was designed using a Colpitts oscillator. The results of the experiment showed that each oscillator oscillates reliable when injection signals(840kHz, 500kHz) are injected. Through the results of a single injection locking experiment, it is confirmed that injection locking phenomena can be applied in the design of the multi-frequency generator.

Beside fire resistance, for Phenolic Composites(here-in-after PCs), in actual, moisture resistance are also needed when they are applied to components in wet uses such as in Naval vessels and in off-shore operations where direct water contact may be expected. PCs have so-called 'Micro-porous' when they are made by normal GRP manufacturing techniques, which causes much larger amounts of water absorption in them to higher level of around $7\%$. So, this figure, which indicate impending disaster in a polyester matrix laminate, has made some specifiers suspicious of the effect of the water on mechanical performance of PC in 'wet' service. To solve this problem, a large amount work has been carried out by workers in UK and US. This paper is an attempt to explain that the effect of the high water absorption of PCs is not the disaster that some 'prophets' may foretell. Let's open our next door fur better society much safetyfied by our own efforts with PCs. like in UK.

This study originates from the following problematic: Can a social history of design provide a useful methodology for the research and education of Korean design? For the understanding of the modes of socio-cultural approach to design, the chapter 2 compares the narrative mode of designer-centered history promulgated under the influence of Nikolaus Pevsner and that of socio-cultural approach advocated by Adrian Forty. The chapter 3 studies the cases of socio-cultural approach to Korean design through the domestic exhibitions like 'Everyday Life, Memory and History,' 'A Glimpse into the Society through Campaigns,' and 'Design Culture in Korea 1910-1960' which attempted the socio-cultural approach to the visual culture of modern/contemporary Korea. In the chapter 4, this study investigates into the meanings and characteristics of socio-cultural approach in the design research and education, End argues for the necessity of the introduction of qualitative research methodology.
