As rapid aging society comes and people have growing interest in health, health issue has become an important value in modern society. The demand for healthy and comfortable residential environment has also increased and people themselves have made effort to build healthy residential environments. Therefore, the purpose of this study is to identify the characteristics of health housings planned and built by ordinary people. The study analyzed the contents of healthy houses that were broadcasted on TV with the title of healthy houses. Analyzed items were the planning elements and motives of building such healthy houses reflected in the samples of respective healthy houses. The result of the study revealed there were many examples of housings for healing purpose and the planning elements were in the order of architecture elements, natural elements, decoration elements, other elements and technical elements. While the experts usually put priority on technical elements for developing of healthy houses, ordinary people put priority on natural elements. This study comprehensively presents the overall characteristics of healthy houses which ordinary people pursue, on empirical basis. It is expected that this study will inspire to think about the desirable direction of healthy houses for the residents by comparing with or along with the concepts of housings that experts pursue.

The purpose of this study was to measure the indoor air quality of small-scale apartments and then proposed a method to improve the indoor air quality of the small-scale apartments by comparing with the result of indoor air quality in the Clean-Healthy House. In case of formaldehyde, a highly volatile organic compound, the concentrations of indoor measured both in small-scale apartments and the Clean Healthy houses did not exceed- the guideline of Korea. The guideline of Korea for acetaldehyde was not available, so the guidelines of Japan and the World Health Organization were used to measure the concentration of acetaldehyde. The study results demonstrated that three out of seven small-scale apartments investigated exceeded the guideline of Japan; and the preliminary research on the Clean-Health Houses was low at about 30-60% of the guideline of Japan. The result of the VOCs measurement showed that toluene, ethylbenzene, and styrene in some small-scale apartments exceeded the guideline of Korea. However, the Clean-Healthy Houses in the previous studies did not exceed the guideline of Korea with regard to all the pollutants. Therefore, this study suggests the application of the construction standards of the Clean-Healthy house in order to improve the indoor air quality of small-scale apartments. In addition, the current study anticipates that improvement of the indoor air quality in the residential environments should be universally applied, not limited to the type and size of the residence.

There is something valuable in Korean traditional architecture that does not change even after more than a number of years. Each design element of traditional houses has its own role to embody natural, healthy, and environment-friendly architectural planning. With traditional already-built examples located in the northern area of Gyeongbuk province, this study attempts to untangle some of the daylighting control issues in opening design. By looking at more than just photometric materials, at some threshold level, the whole of daylighting control characteristics of their openings is being surveyed from the viewpoint of geometric relationship between their roof structures and windows. As a glazing material, in addition, Korean traditional window covering paper, Changhoji, is evaluated for its transmittal performance under artificial and real skies as well.

The concepts of interior design work have set forward an aesthetic and functional proposition to be answered by those who design spaces. The available range of suitable materials for interior use appears to be almost inexhaustible in this day and age. Now a day, relatively new fields of study on environmental-friendly interior examine humans'innate affinity for health and explore its implications for architecture and the built environment. A growing field of research suggests that spaces' relationship to aesthetics and environment can either help or hinder their occupants' health and wellness, productivity, and even their creativity. This paper presents several examples of already built apartment houses in practice, and discusses the demand of users of the spaces for health and sustainable environment, deepening the relationship between newly-constructed spaces and the remodeled ones. The considerations to some new and contemporary materials from the aspect of healthy indoor architecture design are presented in this paper. Designers need to rethink the conventional and high-tech interior environment in apartment houses with respect to perceived air quality, material emissions, and odors. The future of interior design is oriented on light shapeable materials which are able to create a unique memorable atmosphere. The primary assignment in accepting recent materials and proceedings is our responsibility to creating proposals, that are mainly safe, hygienic and environmentally proper.

There are many research Papers and experiments indicating that the geomagnetic field affects the people and living organism. People grow up and build up most of their character through living in dwelling space and have relax and refresh at home. Creating healthy dwelling space is being considered very important in architectural planning and design for providing comfortable living environment and improving quality of life. Therefore. it is necessary to investigate the geomagnetic field and people's response in living space. In this study the vertical component(Z value) of geomagnetic field in detached houses was measured, evaluated by related evaluation criteria, compared with interview survey.

This study aims to present the fundamental strategies to improve the Indoor Air Quality (IAQ) in apartment buildings. To investigate the concentration of indoor air pollutants such as radon, formaldehyde, and VOCs, both the document survey and the field measurement were conducted. In addition, to identify the source of the air pollutants, the laboratory experiment was carried out for various building materials. Finally, the minimum period to be reserved befor3e building occupation to ensure healthy IAQ, which largely depends on the ventilation rates, was simulated using a simple compuer program. The results of this study can be summarized as follows: 1. In case of newly-constructed apartment houses, concentrations of formaldehyde, VOCs and radon were found to exceed the standard. Meanwhile, at existing apartment houses, concentrations of VOCs, particularly toluene and xylene, highly exceeded the standasrd level. Concentrations of formaldehyde and radon, however, had been lowered according to the duration of occupation. 2. The laboratory experiment of concentration of pollutants per square meter of building material surface area showed that radon gas was much emitted from the gypsumboard; formaldehyde from flooring and wallpaper; and VOCs from paints and kitchen furnishings. The emission rates of formaldehyde and VOCs were proportional to air temperature. 3. According to the simulation of the minimum period to be reserved before occupation, newly-constructed airtight houses required about 190-200 days, and naturally ventialted houses with fully-open-windows required about 20-45days, in order to keep the level of radon gas lower than standard. Therefore, with the current practice, the date of occupation should be delayed for about 15 days.

The purpose of this study was to investigate actual sleeping environments in Ondol rooms depending on the season. The experiment was performed on five healthy women. The bedroom environments using Ondol were measured in five cases (three apartments and two houses). The environments in bedroom, bedding temperature, skin temperature and thermal sensation were measured continuously through the seven days for each season in real life. This data of sleeping environments were analyzed in the view of seasonal variations and housing types. Annual average bedroom temperatures: $26.2{\sim}31.0^{\circ}C$ in apartments, $15.7{\sim}33.6^{\circ}C$ in houses. Annual average bedroom humidity: 48.3~82.1% RH in apartments, 64.9~87.0% RH in houses. During sleeping, temperatures of contact surfaces like sheets and under quilts ranged between $30.5^{\circ}C$ and $34.1^{\circ}C$ regardless of season or housing type. Annual average rectal temperature was $36.8^{\circ}C$ with no significant difference in season or housing type. In the point of thermal sensation, neutral temperature of the bedroom was $25.9^{\circ}C$ in apartments and $20.3^{\circ}C$ in houses. It was concluded that in spite of thermal environmental variations according to the seasons, skin, bedding and bedroom temperatures in apartments were better and more stable than those of houses. It is regarded that while houses are brick structured, apartments are steel-frame structured. Due to better insulation and air tightness, apartments were affected less from outdoor temperature and maintained higher room temperature than houses.

In Japan, a lot of elderly housing types have been developed in order to meet various needs of the older person and the change of social situations. Elderly housings can be divided into three categories elderly housings for healthy older persons, elderly care homes for the healthy and elderly care facilities for the unhealthy. Elderly housings include public and private rental housings. Sometimes they can be designated only for the elderly. Elderly care homes for the healthy elderly include full fee charging elderly housing, elderly homes, low fee charging elderly homes and care houses. Elderly care facilities for the unhealthy elderly consist of full fee charging elderly care homes, group homes for the dementia, elderly health facilities, nursing homes, elderly hospitals, and so on. However "elderly care facilities" have been proved not to be efficient for the delivery of elderly welfare services nor satisfactory to the frail older person. Therefore, based on the concept of the "Normalization", daily services have been provided for the elderly in order that they can live at their own home in the community for themselves. As a result, Japan aims not only to reduce elderly welfare expenses but also to increase elderly users' satisfaction. Emphasis on non-institutionalization and in-home services, regional characterization, harmony between Hard and Soft, user oriented services, substantiality, universal design and so on are sought for the sake of those goals.

To assess exposure of allergy patients to a biological environment, measurements were made of levels of airborne bacteria and fungi, house dust endotoxin and mite allergens in homes of 7 allergy patients and 12 healthy families. Concentrations of airborne total bacteria and the ratio of indoor and outdoor concentrations(I/O) in allergy patient's homes were high compared to non-allergy houses. But no significant differences could be shown for the concentration of spores of viable fungi and staphylococcus in indoor air between the homes of allergic patients and healthy families. The results of investigation on house dust mites, Dermatophagoids farinae were detected in all mattress samples and the levels in the allergy patient's homes were generally high, with individual measurements exceeding $2{\mu}g/g$ dust found in $30\%$ samples. In contrast with, Dermatophagoids pteronyssinus were detected in only $60\%$ samples and the concentrations were very low. The levels of endotoxin in dust samples collected from the allergy patient's home mattresses were higher than those of control houses. There was a positive correlation between the endotoxin levels and the house dust mite allergens.

This study was designed to provide the basic data of an effective nutrition education for desirable lifestyle and dietary habits to improve the nutritional status for the elderly by investigating health-related lifestyle, dietary habits, nutritional knowledge, and food intake of the elderly. The subjects included 58 elderly men and 146 elderly women. 35.8% had no more than an elementary school education. Most subjects (54.4%) were widows/widowers. Most subjects (71.0%) made over 150,000 won. 52.5% of subjects lived in houses. Smoking, drinking, exercise, the average sleeping time were significantly difference between the gender (p<0.05). In terms of dietary habits, our results showed that 80.9% of respondent eat regularly meals, including breakfast (83.5%). Both sexes prefer soft and salty food. Women enjoys more spicy and salty food compared with men and then shows meaningful difference (p<0.05). Their favorite meals are soup, stew, salad and boiled vegetables. Compared to women, men have a higher rate of correct answers about questions related to nutrition knowledge as showing significantly difference (p<0.05). In a study of dietary habits, they take in carbohydrates with the highest percentage and following by vegetables and fruits. The amount of meat, first and egg they eat is more than the previously. Eating meat is higher men as showing significant difference (p<0.05). In summary, nutritional status for the elderly shows healthy lifestyle and diet about half of those and most them try to live healthy life in future. It is hope that the elderly may need to learn proper nutrition knowledge for healthy lifestyle and nutrition education and counseling for building up healthy lifestyle and desirable dietary habits. Furthermore, it is necessary to start work to establish a baseline nutritious evaluation for the elderly and at a time to study the development of standard eating tool proven reliability and validity, consequently to provide a basic framework for the evaluation of nutritional status.
