Households of today tend to gradually change from a large household to a small one. The tendency starts from urban concentration of population with modern industrial society. Small-sized households have rapidly increased with the following three reasons: (i) one-person households with aging society, (ii) individualistic pursuit of happiness, and (iii) emergence of single households due to high prices and a decline in the quality of life. With these social changes, various products for small-sized households have been created and there have also been changes in dwelling patterns with small-size housing and one rooms increasing. Current small-sized living space has combined space of a living room, a bedroom and a kitchen, which makes a house compositive space. A bathroom, however, requires a differentiated suggestion from existing one since it is special space where water is used. Based on this issue, this study intends to present bathrooms in small-sized living space.

The purpose of this study was to analyze the differences in housing needs between employed and unemployed wives. A questionnaire survey including 25 questions was done in 90 employed wives and 101 unemployed wives living in Seoul. The findings were as follows: 1) The housing needs for children(educational institute, and community facilities) were high both employed and unemployed wives. The needs for the socialization facilities of household work were low both employed and unemployed wives. The employed wives who have only limited time did not want 24 hours market which is not different from unemployed wives. 2) Unemployed wives wanted larger housing spaces than employed wives did. Unemployed wives put much more value on kitchen size and design. Employed wives considered space for family such as living room and dining room more important than private space.

Volatile organic compounds (VOCs) are considered hazardous air pollutants and these are emitted from building materials and household products. VOCs can cause global warming as well as human sickness, and even cancer. Photocatalysis provides a way of converting VOCs into harmless materials. Various researches have shown that $TiO_2$ is the most efficient photocatalysts due to its excellent activity. In this study, metal/non-metal doped $TiO_2$ particles are synthesized for the enhancement of the photocatalytic properties of pure $TiO_2$. By metal/non-metal doping, band gap energies of prepared samples were analyzed by UV/Visible spectrophotometer. The physical and chemical properties of synthesized powder were characterized by field emission scanning electron microscope, by BET for measuring their specific surface area, and by XRD for phase identification and particle size determination. Degradation ability for p-xylene was evaluated through monitoring the concentration in a closed chamber. Relation between their properties and decomposition abilities for VOC were evaluated based on the experimental results.

Domestic city gas is supplying in an about 10 million household on present 34 city gas companies because is begun to supply regularly after two 1980 years middle. But, result that focus on city gas supply spread and stable supply for supply area and neglects about safety problem, hundreds casualties such as Ahyun explosion accident and Deagu city gas explosion accident were reached in situation that occurred large size calamity occurs it is dizzliness. In the case of advanced nation, can see that accomplish system and progress that in technology after experience major accident. Therefore, grasp problem investigating safety actual conditions for city gas institution and study about solvable plan is required this. Also, must guide reform and level elevation of a domestic company safety technology through induction and development of safety technology that is suitable in supply, domestic real condition etc. Must help in power positivity that is full text executing high-quality safety education about step High firing mechanism safety technology than present safety education.

This study was intended to examine the effects of socioeconomic status on housing values, norms, and behaviors of young households. The purpose was accomplished using the Life Style Survey of 2001 in Ulsan, and the data from 370 households were analyzed. The importance of household income and current housing size which are used as a proxy for socioeconomic status in explaining housing values, norms, and behaviors were once again confirmed in this study, even if there were some other significant variables. This implies that housing values, norms, and behaviors tend to change according to the socioeconomic characteristics of the households under the conditions of controlling demographic ones.

This study was performed by measuring the minimum ignition temperature of polyurethane form recovered from the recycling process of the end-of-life home appliances. The critical ignition temperature of polyurethane form was lower as the size of the sample vessel was increased, and that of polyurethane form using cyclopentane as the forming agent was relatively lower than the polyurethane form using CFC and the combustion of cyclopentane-polyurethane form occurred fiercely. It is considered that the recycling process of end-of-life home appliances using cyclopentane-polyurethane form as the insulator would require a special fire and dust explosion prevention measures since there exists a high potential hazard of fire and dust explosion during crushing and storage processes.

Agriculture in Swaziland is the most important sector of the economy from the stand point of export earning, rural employment and dependency for family food. But, inspite of 65.5 percent of the household being busy in food production for family consumption in Swaziland, the import bill of food and live animals is rising from E119.7268 million in 1987/90 (An.St.Bul.1988) . A typical farm size, based on holding's growing crops, is only 1.93 ha which may prohibit owning a four wheel tractor for farm operations. The traditional hand tools are just not efficient and comfortable to operate in order to exploit full potential of the land. There are over 120.000 draught animals which have potential to be utilized in farming. The two wheel-tractor is another energy source which can be used for many farm-operations.

The purpose of this study was to explore the factors related to depression of married baby-boomer female by employment status. Data for this study was based on a convenience sample of 499 married female baby-boomer who have residence in Busan and Gyeongnam province. The prevalence rate of depression symptoms was 21.4%. The employment status made differences on the factors related to depression of married female baby boomers. Depressive symptoms were significantly associated with attitudes toward menopause, menopausal symptoms and marital satisfaction for both baby-boomer female with and without a job. While monthly household income, participation in voluntary associations and satisfaction with children were significantly related to depression symptoms of baby-boomer female without employment, perimenopausal stage, perceived size of social network was important factors for the depression of married female baby boomers with a job.
