The purpose of this study is to suggest optimum size of residents' bedrooms in nursing homes. Bedroom is an essential part of nursing homes because nursing home residents spend most of their times in bedrooms and occupy the largest part of facility area. Therefore it is necessary to set an adequate standard related to resident room area in nursing facilities, which have a great effect on planning longterm care facilities for the elderly. The body dimensions of elderly people and care givers have been collected from the previous study. Based on the body dimensions data, the behaviors of elderly as well as care givers have been analysed. The minimum areas-exclusive of toilets, closets, vestibules and so on - have been proposed from the results of the behavior analysis.

Objectives: Exposure to airborne bacteria is associated with adverse health effects such as respiratory and infectious diseases. This study evaluated airborne bacterial concentrations in the living rooms, kitchens, and toilets of 30 homes. Methods: Bacteria were sampled with an MAS100 impactor in three spaces in the subject homes between April 2014 and February 2015. Bacteria were grown on TSA plates for 48 hours at $35^{\circ}C$. The bacterial strains were isolated and amplified by polymerase chain reaction. Results: The most culturable bacteria were found in toilets ($624.0CFU/m^3$, GM: $417.3CFU/m^3$), followed by in the kitchen ($503.8CFU/m^3$, GM: $324.9CFU/m^3$). The dominant genera identified were: Staphylococcus sp.(19%), Micrococcus sp.(16%), and Bacillus sp.(11%) in the indoor air and Bacillus sp. (30%) in the outdoor air. Gram-positive bacteria comprised more than half of all colonies. Conclusion: In this study, culturable bacteria concentrations were higher than those reported in other spaces. Therefore, it is important to control relative humidity and remove moisture to prevent bacteria from multiplying. Additionally, the dominant species in indoor air were Staphylococcus sp. and Micrococcus sp. These are found on the human skin, mucous membranes, and hair, so human activity can affect bacterial distribution. Therefore, cleaning and controlling moisture are important for reducing indoor bacterial concentrations.

Struvite (MgNH₄PO₄ ⋅ 6H₂O) and hydroxyapatite (HAP, Ca₁₀(PO₄)₆(OH)₂) precipitation in urine-separating toilets (NoMix toilets) causes severe maintenance problems and also reduce the phosphate and calcium content. Application of urine separating technique and extraction of by-products from human urine is a cost effective technique in waste water treatment. In this study, we extract urine calcite from human urine by batch scale method, using urease producing microbes to trigger the precipitation and calcite formation process. Extracted urine calcite (calcining at 800℃) is a potential adsorbent for removal of heavy metal(loid)s like (Cd²⁺, Cu²⁺, Ni²⁺, Pb²⁺, Zn²⁺ and As³⁺) along with additional leaching analysis of total nitrogen (T-N), phosphate (T-P) and chemical oxygen demand (COD). The transformations of calcite during synthesis were confirm by characterization using XRD, SEM-EDAX and FT-IR techniques. In additional, the phosphate leaching potential and adsorbate (nitrate) efficiency in aqueous solution was investigated using the calcinedurine calcite. The results indicate that the calcite was effectively remove heavy metal(loid)s lead up to 96.8%. In addition, the adsorption capacity (q_e) of calcite was calculated and it was found to be 203.64 Pb, 110.96 Cd, 96.02 Zn, 104.2 As, 149.54 Cu and 162.68 Ni mg/g, respectively. Hence, we suggest that the calcite obtain from the human urine will be a suitable absorbent for heavy metal(loid)s removal from aqueous solution.

Interest in weekend farming has been increasing recently among city-dwellers although it is still only in the beginning stages. Weekend farming has been increasing recently among city-dwellers although it is still only in the beginning stages. Weekend farms provide people with new activities and also help to preserve green areas within the city. It is necessary to understand what weekend farm users think and what problems they encounter in order to increase the use of these farms. For this reason, we studied 16 weekend farms in Seoul managed by the Rural Guidance Office and the Agricultural Cooperative. We distributed 24 questionnaires by hand and these were later returned by mail. The questionnaire asked weekend farmers about their motivation for using the farms, about their motivation for using the farms, frequency of use, level of satisfaction, current state of housing and the sort of plants they cultivated, among other things. We found that most of them live in apartments and have little access to green areas,. Weekend farm users were generally satisfied. However, they had a lack of gardening knowledge and reported that facilities such as toilets and water service were unsatisfactory. Political support is needed from the government in order to improve weekend farms. There needs to be a wider range of farm sizes and an increase in the uses of the farms. If these improvements occur, investment in and the development of weekend farming will increase and weekend farms will take root in Korea.
