This study aims to compare the energy consumption characteristics of high-rise and general apartments and propose policy implications in Incheon City where high-rise apartments are planned. The method of analysis is to select the cases, to conduct field survey, drawing review, analysis of Electric Architectural administration Information System. The study derived the current status of energy consumption in high-rise and general apartment complexes located in the same region, Yeonsu-gu Incheon City, and performed comparative analysis on their characteristics. First, electrical energy in the high-rise apartment complexes was consumed excessively, by 1.63 to 2.5 times more than that of the general apartment complexes. Second, the gas energy usage in the high-rise apartment complexes was higher than that of the general complexes, by 1.09 to 1.2 times. Third, the energy consumption per unit area in the high-rises was also higher, by 1.042 to 1.3 times. As individual elements such as incomes, living standards, and life patterns of the residents affect energy consumption, the high-rise apartment complex consumed more energy per unit area than the general apartment complex did. However, this study did not consider the elements of energy expenditure and satisfaction level, which are the limitations of this research.

As energy conservation can be realized through changes in the composition of goods and services consumed, there is a need to assess indirect and total household energy consumption. The Korean household sector was responsible for more than 55% of Korea's total energy consumption in the 1995 to 2010 period. More than 69% of household energy consumption was indirect. Thus, not only direct but also indirect household energy consumption should be the target of energy conservation. Electricity consumption became in 2009 the main source of household energy consumption in Korea. Households consume more and more electricity intensive goods and services, a sign of increasing living standards. Decrease in energy intensities of products consumed by Korean households contributed greatly to reduce the increase in the total household energy consumption. However, switching took place towards more energy intensive products, thus the structure effect was negative. It is necessary to direct consumption and production towards much less energy intensive goods and services as to reduce energy consumption or its growth rate. The Korean government should readjust low energy and electricity prices to cost-reflective prices levels as these low prices are one of the main reasons for the consumption of more energy intensive products. This study differentiates prices of oil products and electricity between households and industries, as to allow more accurate estimation.

기존의 지능형 홈은 주거환경에서의 사용자의 편의성이 중심이 된 IT기술 기반의 홈 네트워크 중심 기술이었기 때문에 에너지 절감 측면에서의 기술 적용은 거의 이루어지지 않았으며 적용된 기술 또한 기술적 수준이 매우 미흡하였다. 본 논문에서는 이러한 주택 환경에서 에너지 절감 효율을 끌어올리기 위한 요소 인프라 기술을 유도해 내기 위해 실제 사용자의 생활 행위 패턴을 에너지 절감을 위한 구성 요소로 파악하여 실제 이러한 생활 패턴을 정형화 할 수 있는 데이터 베이스를 구축하기 위한 할 수 있는 테스트 모델을 셋업하였다. 이를 위해 복도, 출입구 그리고 현재 근무 중인 테이블에 조도 센서와 인체 감지 센서를 설치하였는데 조도 센서와 인체감지 센서는 하나의 그룹을 이루며 생활패턴을 파악하고 조도 값에 따라 실내등을 소등할 수 있도록 한다. 개개의 센서 노드에서 수집된 센싱 데이터는 브릿지에 있는 베이스 노드로 수집되고 이는 인터넷망을 통해 서버로 전달되어 DB 구축되어 진다. 이러한 시뮬레이션 테스트 모델을 통해 에너지 소비 상태를 파악하고 정형화 함으로써 에너지 절감을 위한 기술 구현이 가능해 진다.

The main purpose of this study was to investigate the relationship between financial management behavior and subjective level of consumption of rural households. In this study, financial management behavior was defined to include 'budgeting' and 'expenditure management'. Data were collected from the 215 rural households in 13 different provinces of Chungnam, and 203 households were used for the analysis. Frequency distribution, means, and path analysis were employed for the statistical analysis. Major findings were as follows. Budgeting behavior had a significant positive effect on rural households' subjective level of consumption, while expenditure management behavior didn't have any significant effect. This implies that active and systematic financial management behavior such as budgeting is more effective than relatively passive financial management behavior like expenditure management on the enhancement of economic well-being of rural households. Age, education, and number of non-farm earners had indirect effects on the subjective level of consumption through budgeting behavior. Income stability had a direct effect and income had both direct and indirect effects on the subjective level of consumption.

우리나라는 1960년대부터 경제성장에 주력한 결과, 국민들의 생활수준은 크게 향상되었으나, 대량생산과 대량소비 생활이 보편화되어, 부수적으로 발생되는 도시쓰레기의 량이 증가하고 있다. 1997년 말 현재 매립장은 전국적으로 537개소, 총 면적은 36,030천$\textrm{m}^2$에 이르고 있으며, 2001년에는 1997년 말의 약 3배가 될 것으로 예측되고 있다. 매립장 인근 지역에 거주하는 주민들에 대한 설문조사 결과를 살펴보면, 환경오염 피해 중 악취에 의한 피해와 침출수로 인한 지하수 오염문제를 가장 심각한 문제로 인식하고 있는 것으로 나타나,이러한 문제에 대한 뚜렷한 해결 방법이 제시되지 않는 한 혐오시설로 인식되어진 매립장에 대한 인근주민의 거부감은 줄어들지 않을 것이다.

Today seafoods, such as fisheries and clams, have become an important part of our diet. But processing and storing these perishable seafoods for a long period of time present a serious problem. Only a few years ago, the seafood consumption was minimal. However, an improvement in our diet has enabled us to enjoy seafoods more often than before. Moreover, the recent trend toward the concentration of the popuration to the metropolitan area and the improvement in the standards of living have accelerated a change in our food consumption pattern-preference for the convenient foods over time consuming cooking. Judging from these changes, we can easily predict that the demand for the covenient, dried seafoods will rise sharply in the coming days. The development for an innovative and attractive way to package and market these products are on the way. Research and development of the distribution channel and package design of the dried seafoods will offer a wide array of opportunities to increase the sales volume of the dried seafoods. In addition, by associating the image of Pusan, as a prime oceanic city, with the dried seafoods on the package will certainly draw the attention of many prospective consumers. Consequently it will make the dried seafoods special products of Pusan, and eventually contribute to the prosperity of the city.

The purpose of this study is to suggest the design parameters, which are applied to the solid waste treatment and management systems in rural area. In order to drive out the parameters, the solid waste production and management systems in rural and urban areas had been surveyed and analyzed, respectively. The comparisons of the analyzed results are also introduced in the paper. The rural areas referred to the survey are grouped in accordance with the industrial activities in those areas. The conclusions of the study are as follows: 1) The solid waste volumes produced per day per capita in rural area are less than those of urban area. For example, the average volume produced in rural area in 1995 is 0.85kg, which is two thirds of those in Seoul area. 2) for the treatment, the country has depended mainly on landfill. On the other hand, the incineration treatment ratio has been in creasing in rural area. 3) The physical and chemical properties of the rural solid waste, according to the analysis, are similar to those of the urban areas, which means the living pattern in those two areas have a little difference.
