이 연구는 텔레서비스가 개인의 통행행태 및 교통수요에 미치는 영향을 분석하기 위한 것이다. 먼저 개별행태 모형에 기초한 가구원별 통행통신행태조사를 실시하고, 이 분석결과를 바탕으로 서로 상이한 업무행태를 보이고 있는 9개의 군집이 분류되었다. 다음으로 "가설 시나리오"기법을 이용하여 텔레서비스에 의한 교통수단의 대체 가능성을 추정하였다. 개별 군집 중 "가정주부"와 "노년/무직자"의 경우 향후 텔레서비스의 활용에 어려움 등, 정보화사회에서 소외될 가능성이 높을 것으로 예측되었다. 텔레서비스로의 전이확률을 추정한 결과 은행이나 관공서업무와 같이 교류되는 정보종류가 텍스트나 데이터와 같이 단순한 형태일 경우 높게 나타났다. 이러한 연구결과를 근거로 서울시의 경우 텔레서비스에 의하여 향후 일일 약 7.6%의 통행수요가 대체될 수 있을 것으로 예측되었다.

본 논문에서는 MPEG-4 HE-AAC의 SBR 부호기의 효율을 개선하기 위해 예측 SBR(Predictive-SBR)을 제안한다. SBR 부호기는 주부호기(core encoder)와 결합하여 적은 비트량으로 고주파 성분을 복원할 수 있게 한다. 본 논문에서는 SBR 데이터의 약 70%를 차지하는 포락선 정보를 부호화하는 방법을 개선하여 효율성을 높이고자 한다. 기존 SBR은 포락선 정보의 전송을 위해 다음과 같은 방법을 이용한다. 먼저 고주파 대역의 에너지를 스케일팩터 밴드 단위로 계산한다. 다음으로, 전송정보량의 감소를 위해 델타 코딩 방식을 이용하여 에너지 정보를 부호화한다. 본 논문에서는 SBR의 포락선 정보를 효과적으로 감축하기 위하여 고주파 대역의 에너지를 예측하는 방법을 이용한다. SBR 부호기의 입력 데이터가 SBR 복호기의 입력데이터와 동일하다는 가정 하에 선형 회귀(linear-regression) 기법을 이용하여 고주파 대역의 에너지를 추정한다. 그 후에 추정된 에너지와 원래의 고주파 대역 에너지의 오차를 델타 코딩을 이용하여 부호화한다. 정보를 전송할 때는 고주파 대역 에너지의 델타 코드와 예측 SBR에서 계산한 오차의 델타 코드 중 부호화에 필요한 비트량이 적은 방식을 선택하여 부호화하도록 한다. 그 결과 약 10% 정도의 정보량 감축 효과를 얻을 수 있다.

The purpose of this study was to examine the factors affecting financial satisfaction of rural housewives. Data for this study were collected from 202 households living in 8 provinces. The results were as follows; 1) The most frequent financial problems experienced from expenditures on clothes(82.1%), lack of expense for social intercourse (61.47), and difficulty in purchasing durable goods(60.1%) in the order. 2) 44.6% of the respondents said they were satisfied with their net worth, and 21.6% of them confessed they had difficulties in debt redemption while 52.5% of them said they felt pressure about monthly payments of installments, which reveals that farm households find it hard to pay back short-term debt. 3) The path analysis was adopted to see the causal relations among the variables influenced the financial satisfaction. The variables of experiences of economic problems, educational background(graduated from middle school), saving, income, and age appeared to be important in the order of effectiveness. Among them, the variables of saying and experiences of economic problems showed a direct effect, and those of age and saving displayed an indirect effect with the experiences of economic problems as the parameter. From this findings, it is suggested that rural extension workers and educators should emphasize the importance of the financial plan in their educational programs.

The purpose of this study was to investigate the relationship between clothing interests in the status symbol and the exhibition need and status inconsistency. The exhibition need was measured by Murray's statements on need and some items selected from The Need Diagnosis Scale of Jaung-Kyu Whang. Status inconsistency was measured by the same criteria of Lenski. Three aspects of clothing interests-the status symbol, the fashion and the exhibitionism-were assessed. The questionnaires were distributed to the housewives in Seoul. Data from 511 respondents were analyzed by correlations and $x^2$-tests. The results were: 1) The exhibition need was positively related to interests in the status symbol and exhibitionism of clothing. 2) Status inconsistency was positively related to clothing interests in the status symbol and fashion. 3) The degree of clothing interests in the status symbol and fashion were also positively related to the clothing expenditure and the socioeconomic status of the sample.

The purpose of this study was to investigate whether or not the clothing behavior of house-wives in Seoul vary depending on their socioeconomic status. The null hypotheses tested in this study were as follows: 1) There are no differences in housewives' attitudes toward the importance of clothing according to their socioeconomic status. 2) There are no differences in housewives' criteria of clothing choice according to their socioeconomic status. 3) There are no differences in housewives' clothing taste according to their socioeconomic status. 4) There are no differences in the pattern of housewives' clothing purchase according to their socioeconomic status. In order to test these null hypotheses, questionnaires on clothing behavior and socioeconomic status were distributed to a sample of 243 purposively selected housewives in Seoul, Korea. The factor analysis, correlation and analysis of variance techniques were employed for the statistical analysis of data. The results indicated that: 1) The attitudes toward the importance of clothing was related to socioeconomic status. 2) The criteria of clothing choice (aesthetics-practicality), clothing taste (individuality-conformity), and the pattern of clothing purchase (a degree of rationality) were not related to socioeconomic status. 3) The criteria of clothing selection was related to housewives' level of education. 4) Clothing taste was related to housewives' age.

This study was designed to examine the decision-making and family life satisfaction of the urban middle-aged housewives from the ecological perspective. The main purpose of this study was to investigate the effects of ecological enviornment variables(ie, natural physical-biological environment·social-cultural environment·human-built environment) and their dicision-making on their family life satisfaction. Also, it is to provide some fundamental information that helps to elevate the family life satisfaction of the unban middle-aged housewives. The subjects of this study were 305 housewives living in Seoul and Inchon area, whose age was from 40 to 59. The significant results were as follows: 1) Their decision-making was affected by the following variables in the order of health condition, fate-control orientation, husband’s support, monthly family income and the perception of the adequacy of household income. 2) The ecological environment variables which had an influence on family life satisfaction were the perception of the adequacy of household income, husband’s support, fate-control orientation, health condition and educational level. 3) From the regression analysis, the model was found to be highly significant, accounting for 44% of the variance. Thus, husband’s support was the strongest predictor variable.

This qualitative case study examined the experience of middle-aged homemakers with buying and wearing clothes. Clothing benefits and clothing purchase types were observed in the homemakers' daily clothing-related behavior. This study aims to understand clothing consumption values in light of clothing benefits and to determine purchasing methods, purchasing mental states, and personal characteristics according to the clothing purchase types of middle-aged homemakers. The participants of this study were four full-time homemakers and four homemakers with a job outside the home, all in middle age. This study was conducted through in-depth interviews based on an unstructured questionnaire, and the data were collected from January 2010 to October 2010. The results were as follows: first, the clothing benefits were identified as a social stereotype, aesthetic taste, economy, wearing situation, and age perception. The most important clothing consumption values to the middle-aged homemakers based on the observed clothing benefits were, in order: social value, emotional value, epistemic value, functional value, and conditional value. Second, the type of clothing purchase was observed to be planned buying, followed by impulse buying, and compensatory buying. Even when a homemaker planned to shop regularly, when they were exposed to an attractive retailer promotion, they seized on the opportunity on impulse or made a compensatory purchase to divert oneself. Even though homemakers prefer primarily impulse buying, when they went shopping for clothing with their mother-in-law or husband, they made planned purchase also.

The purpose of this study is to offer basic data of education to improve farm lives though investigating rural homemakers' life style. The results of this study are as follows : 1. The life structure of rural homemakers was classified into two structures as a material resources and human resources. The life style of rural homemakers was classified into systematical life style, traditional value style, social active style, and progressive active style. 2. The life styles of rural homemakers according to social population variance were as follows. The lower of age, homemakers whose family incomes more 30 million won or below 10 million won, who has religions, who employed in livestock were showed at very systematical life style. The homemakers who live in mountain village, higher the much age becomes, and the education level become lower, have showed traditional value style. Rural homemakers the lower of age, the higher incomes, composed of single parent ＋ children who remain single were appeared social active style. Rural homemakers the lower of age, the more shortened farm life periods, who employed in livestock were appeared progressive active style. 3. Systematical life style was more affected by material resources structure, traditional value style was affected by material resources. And social active style was more affected by human resources, progressive active style was affected by human resources.
