본 연구는 빈곤가구의 소비패턴이 단일 유형이 아니라 여러 유형으로 나타나고 있으며, 그러한 차이에 어떤 요인들이 관련되어 있는지 분석하였다. 연구결과 빈곤계층을 하나의 소비유형으로 단순화 할 수 없으며, 사회 환경의 변화에 따라 필수품의 목록이 변화하였고, 변화의 양상은 라이프사이클이 상이한 가구원의 구조에 영향을 받는 것으로 파악되었다. 소비패턴의 유형은 여섯가지로 분류되었는데, 각각은 교육비지출형, 식료품지출형, 사회적관계지출형, 교통통신비지출형, 의료비지출형, 주거비지출형으로 명명할 수 있었다. 각 소비패턴유형에 영향을 미치는 요인을 분석하기 위하여 다항로짓분석을 실시한 결과 빈곤가구의 경제적 특성보다는 가구특성, 가구주특성, 사회적 특성이 유의미한 영향을 미치는 것으로 확인되었다. 연구결과 빈곤가구의 다양한 욕구를 확인했고, 소비패턴의 영향 요인이 경제적인 요인보다는 가구의 인구사회학적 요인이 더 큰 영향을 미치고 있음을 감안할 때, 한시적인 소득지원에 무게를 두고 있는 한국의 빈곤정책은 가구의 욕구에 기초하여 다양하게 접근해야 할 필요성이 있다.

The most prevailing consumption pattern of chicken was "Buy fresh and cook at home (79.8%)". The frequency of eating chicken dish was about "Twice a month". Total average of degree of Preference is "2.30". It is very much close to "Like (2.0)" rather than "Average (3.0)". The degree of preference of chicken decrease as the age increase. About 30% of the housewives have the experience of buying chicken "Cut-up". But "Whole chicken (79.7%)" was still used mostly for chicken dish at home. As the education background improves or living expense increases, housewives purchase chicken "Cup-up" more frequently. The major criteria in purchasing chicken was "Hygiene (67.4%)""Quality (55.2%), "Expiration date (36.7%)" follows next. The groups of ′Above 50 years′, ′Graduate school′ and ′More than 3 million won′show greater interest about "Health" than any other groups. Major chicken dish at home in Korea was "Chopped hot chicken (70.7%)". "Boiled chicken soup (43.2%) \" and "Ginseng chicken soup (39.3%)" follows next. "Order for delivery (57.4%)" increased rapidly for chicken consumption. Croup of ′20~30 years′ order chickens for delivery more frequently than other groups. But as the age of housewives increases, they cook at home more frequently. The most preferred chicken dish for dining-out were "Fried chicken (69.4%)" and "Spicy chicken (57.4%)". The preference of Korean traditional dish for dining out was decreasing except "Chuncheon chicken rib (14.2%)".2%)".

These days, mobile embedded systems adopt flash memory capable of XIP feature since they can reduce memory usage, power consumption, and software load time. XIP provides direct access to ROM and flash memory for processors. However, using XIP incurs unnecessary degradation of applications' performance because direct access to ROM and flash memory shows more delay than that to main memory. In this paper, we propose a memory management framework, dynamic XIP, which can resolve the performance degradation of using XIP. Using a constrained RAM cache, dynamic XIP can dynamically change XIP region according to page access pattern to reduce performance degradation in execution time or energy consumption resulting from native XIP problem. The proposed framework consists of a page profiler gathering applications' memory access pattern using PMU and an XIP manager deciding that a page is accessed whether in main memory or in flash memory. The proposed framework is implemented and evaluated in Linux kernel. Our evaluation shows that our framework can reduce execution time at most 25% and energy consumption at most 22% compared with using XIP-only case adopted in general mobile embedded systems. Moreover, the evaluation shows that in execution time and energy consumption, our modified LRU algorithm with code page filters can reduce more than at most 90% and 80% respectively compared with applying just existing LRU algorithm to dynamic XIP.

To investigate the consumption pattern of traditional fermented soybean products a survey was con-ducted to the subjects composed of 308 housewives in busan yangsan and ulsan. Doenjang was rated among one of the often-used traditional foods in Korean meal preparation. 67.2% fo the respondents used Doenjang once or twice a week and 22.7% every day and by the educational level the lower in education level used more. Doenjang has been prepared by housewives themselves(46.9%) or by their relatives(30.7%) for the most important reason of good taste and by purchasing of commercial products(22.4%) for convenience. By regional groups the frequency to use commercial products of Doenjang was higher in Ulsan and the younger or the higher in education level showed the higher frequency. The consump-tion pattern of Gochujang was very similar to that of Doenjang. Chunggukjang which has peculiar flav-our showed very low consumption with being rarely used or having not eaten by 60.3% of subjects. Gan-jang was consumed mainly once or twice a week and jin-ganjang was preferred than Guk-ganjang. In the preparing methods Guk-ganjang have been made by housewives themselves(31.0%) by their relativ-es(29.5%) or by purchasing of commercial products(31.0%) and Jin-ganjang mainly by purchasing of commercial products(65.0%) which showed higher consumption frequency of commercial products com-pared with Doenjang and Gochujang.

This study is aiming to suggest baseline date for the establishment of policy alternative to make healthy consumption life of the elderly through investigating and analyzing actual condition of consumption related with the awareness of health functional food such as purchase behavior and consumer's problems about health functional food. Under the assumption that the vitalization of health functional food market will become an important market in the present and in the future, the fundamental marketing information about elder consumers is more important than any other information that is essential for successful marketing to domestic corporations and senior policy experts. In addition, there was a fundamental significance to provide necessary basic data for health promotion of the elderly by offering information about rights and interests of elder consumers who are members of vulnerable social group or right choice of purchasing or intake. The limitations of this study are as follows. First, the subjects were selected who live in Gangwon-do with the age of 60 and over due to the limitation of sampling, and that might be shown local characteristics. Therefore, the study result could not be generalized on behalf of all elderly in Korea and it is difficult to apply the result to more segmented market. To solve this problem, studies containing sampling by regional groups might be needed.

본 연구에서는 소득과 소비의 불평등을 비교하고, 소득과 소비의 상호 연계에 있어서 항상소득가설의 역할을 분석하였다. 1990년 이후 소득 불평등도는 계속 심화되는 추세를 보였으나, 소비의 불평등도는 2000년대 초반까지 오히려 완화되다가 이후 소득의 불평등도와 동행하는 양상을 보이고 있다. 이는 2000년대 초반 이후 소비에 대한 제약이 충분히 완화되어 우리나라 가구의 소비가 항상소득에 의해 결정되는 양상이 정착되고 있음을 반영하는 것으로 판단된다. 결과적으로 2003년 이후 소비와 소득의 불평등도가 동행하는 양상은 소득의 불평등도 변화에 있어서 항상적 요인의 불평등도가 변동하고 있음을 의미하는 것으로 평가된다.

Energy consumption of sensor nodes is minimized because it has limited energy generator in wireless sensor network. Electronic shelf label system is one of application fields using wireless sensor networks. Battery size of small apparatus for displaying price is restricted. Therefore its current consumption have to be minimized. Furthermore the method for minimization of peak current would be considered because life cycle of coin battery used to display or RF is vulnerable to intensity of drain current. In this paper, we analyze current consumption pattern of low-power electronic shelf label system. Then we propose the method for minimization of current consumption by modification of software and hardware. Current consumption of the system using proposed method are approximately 15 to 20 percent lower than existing system and the life cycle of the system is approximately 10 percent higher than existing system.
