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.

This study is to analyze the effect of neighborhood commercial facilities on the homeproduction activities and the family expenditure(or household work time). For this purpose. data are collected by using questionnaires distributed to 522 housewives in Seoul. The results shows that in the highly goods-intensive environment. the way of homeproduction is goods-intensive. Market dependence of the family is affected by homeproduction predisposition. income. and husband's job. Household work dependence of the .family is affected by neighborhood facility environment. family type. income. and house value. Low home production supportability is apparent in the high family income. full-time housewives and low job status of housewife. On the other hand. high homeproduction supportability is apparent in the moderate income and high job status of housewife. As a result. housewives have much time and money resourses are not well supported by the neighborhood facility environment.

The application of Residents Participation Designing Method is to provide the resident with a chance of either participating in the planning process of the house or selecting other possible options. The multi-household apartments have so far been grown in quantity by means of mass production and hence have contributed in elevating its supply. However, this manner of supplying has a tendency of ignoring much of the individuals concern regarding space planning And has therefore repeatedly standardized and stereotyped ground planning which only concerns its economic profit and effectiveness. As the standard of living and personal wealth have improved over the years, residents have come to demand a more futuristic model designed to satisfy the individuals personal taste and lifestyle. Therefore, the purpose of this study is to suggest the planning method of multi-household apartments to correspond to resident's specific demand.

This case study surveyed management situations of environmentally friendly farming (EFF) and their awareness situations. Farmers are aging as an average age of 62-year old. The EFF did not increase farmer's income, however, farm income of EFF was more than that of conventional farming. Farm household liabilities showed large deviation among farmers. Livestock and greenhouse farm households have more liabilities because of facilities and feed cost. Farmers of EFF have been also cultivating conventional farming, but they don't plan much conversion intention of conventional farming into EFF owing to lack of differentiated and stable market for their environment-friendly agriculture products. And they are guessing that EFF income will usually not increase more. For increasing of EFF income, they think that it is necessary to enlarge production area, change to high-income crop, develop processing foods, change to organic farming and so on.

This study applied the Stochastic Frontier Analysis to estimate which independent variable affects to efficiency of aquaculture household. This study used wage and facility scale as input variables, sales volume as an output variable to estimate efficiency. Also, the study used region, species, water quality to estimate technical inefficiency factors of the model. The data used for this study were obtained by the operating costs survey using 1:1 interview method. The study selected translog production model with technical inefficiency term estimated as half-normal distribution. In addition, the study used pearson and spearman correlation coefficient among efficiency estimating models. Also, the study analysed differences among estimated efficiencies through t-test, and showed us 0.1793 in species, 0.4677 between Geojae and Masan.

In the marginal upland areas of East Java, Indonesia, ruminants provide farming households with tradable assets in addition to manure and draught power. Households are interested in acquiring ruminants at an early stage of household development. This paper discusses farmers' access to cattle via sharing arrangements. In these arrangements owners lend animals to other farmers in retum for a share of the offspring or the profits. Livestock owners only entrust cattle to households with prior experience in livestock keeping and sufficient labour. Details of the sharing contracts differ between villages. Changes in cattle numbers and ownership over time are attributed to patterns of the development of village agriculture and the economic development of farming households. Feed shortages in the dry season bring about short-term changes; cattle numbers decline and the proportion of households rearing shared cattle increases. The institution of sharing plays a major role in replenishing herds after periods of severe drought.

This case study surveyed management situations of environmentally friendly farming(EFF) producers' organization and their main activities. Farmers are aging as an average age of 55-year old and producing fruit-bearing vegetables. The EFF did not increase farmer's income, however, price and income was stabilized more than that of conventional farming because of contract farming. Farm household liabilities are caused by purchasing agricultural machinery, materials and so on. Farmers of EFF have been also cultivating conventional farming, but they don't plan much conversion intention of conventional farming into EFF owing to lack of differentiated and stable market for their EFF products. And they are guessing that EFF income will increase a little. For increasing of EFF income, they think that it is necessary to reduce production cost, produce high quality production, develop processing foods, enlarge contract farming and so on.

One of main findings of the competitiveness relation is rapid increase of Chinese influence on the southeast Asian market. While Japanese market share is decreasing, Chinese market share is continuously increasing in the market. It is the same regardless of types of production phases. Analysis based on gravity model shows that in general Chinese exports is crowding out Korean and Japanese export to the market. The magnitude of the effects on Korean exports is larger than on Japanese exports. Also, It is found that the directions of the effect of Chinese exports on Korean and Japanese exports are different by production phrases. For all processed goods, increase of Chinese exports decreases both Korean and Japanese exports to the market. However, for some final goods such as transport equipment and food & beverages for household, Chinese exports is increasing Korean and Japanese exports to the market.

The purpose of this study was to analyze the production and marketing control effects of aqua-cultured flounder required for stable income growth of aqua-cultured household. We analyzed the supply and demand structure of cultured flounder using the partial equilibrium model approach. And we estimated the optimal yield of cultured flounder and analyzed the effect of marketing control through constructed model. The main results of this study are summarized as follows. First, the fitness and predictive power of the estimated model showed that the RMSPE and MAPE values were less than 5% and Theil's inequality coefficient was very close to 0 rather than 1. It was evaluated that the prediction ability of the aqua-cultured flounder supply and demand model by dynamic simulation was excellent. Second, dynamic simulation based on policy simulation was conducted to analyze the price increase effect of production and shipment control of cultured flounder. As a result, if the annual production volume is reduced by 1%, 5%, and 10% among 32,852~37,520 tons, it is analyzed that the price increase effect is from 1.2% to 12.5%. Finally, this study suggests that the production and marketing control can increase the price of aqua-cultured flounder in the market. In this paper, we propose a policy implementation of the total supply system instead of conclusions.

This study investigated the extent to which rice producers from the Ayeyarwaddy Region of Myanmar could improve their productivity if inputs were used efficiently in rice cultivation. To achieve this objective, simple random sampling was used to collect data from 300 rice growers in the study area. Data were analyzed with the translog stochastic frontier approach to understand the production efficiencies. The study further estimated the influencing factors that affect the efficiency levels of rice farmers. The empirical result reveals that the average technical, allocative, and economic efficiencies were at 76.11, 47.85, and 34.15%, respectively. This suggests that there is considerable room for improving rice production by better utilization of the available resources at the current level of technology. This study suggests that strenthening agricultural training programs and adoption of improved rice varieties may reduce overall inefficiencies among rice farmers in Myanmar. Factors like age, household size, education, farming experience, farm size, rice variety, training, and off-farm income have a significant impact on increasing/decreasing farmer's efficiency. Efficiency can be improved by establishing farmer field school programs to increase the scale of operations. The government should encourage young educated people to participate in paddy production and also intervene to reduce input prices and control the quality of seeds.
